Resolution.
SECTION 2. Environmental Review.
1. State CEQA Guidelines section 15164 allows lead agencies to
prepare an addendum to a previously adopted negative declaration if minor technical
changes to the project are necessary, but none of the conditions require preparation of

2 . The City Council has reviewed and considered the Addendum
together with the 2014 Housing Element MND, and finds that those documents taken
together contain a complete and accurate reporting of all of the environmental impacts
associated with GPA 15-003 and RZ 15-001. The City Council further finds that the
Addendum and the administrative record have been completed in compliance with
CEQA and the State CEQA Guidelines . The City Council further finds and determines
that the Addendum reflects the City's independent judgment.
3. Based on the substantial evidence set forth in the record, the City
Council finds that an addendum is the appropriate document for disclosing the minor
technical changes and additions that are necessary to account for GOA 15-003 and RZ
15-001 . The City Council finds that based on the whole record before it, none of the
conditions under State CEQA Guidelines section 15162 requiring the need for further
subsequent environmental review have occurred because:
(a) No substantial changes are proposed which will require major revisions to
the previous negative declaration due to the involvement of new significant
Page 2 05-03-2016
environmental effects or a substantial increase in the severity of previously
identified significant effects ;
(b) No substantial changes have occurred with respect to the circumstances
under which the project is undertaken which will require major revisions of
the previous negative declaration due to the involvement of new significant
environmental effects or a substantial increase in the severity of previously
identified significant effects; or
(c) New information of substantial importance, which was not known and
could not have been known with the exercise of reasonable diligence at
the time the previous negative declaration was adopted, has come to light
that shows the project will have one or more significant effects not
discussed in the previous negative declaration.
NOW, THEREFORE, BE IT FURTHER RESOLVED, based on the
substantial evidence set forth in the record, the City Council of the City of San Juan
Capistrano herby adopts the Addendum to the 2014 Housing Element MND,
incorporated herein as Exhibit A.
SECTION 3. General Plan Amendment.
NOW, THEREFORE, BE IT FURTHER RESOLVED, that the City Council
of the City of San Juan Capistrano does hereby make the following findings as
established by, Section 9-2.307, Amendment to the General Plan of Title 9, Land Use
Code of the City of San Juan Capistrano:
The San Juan Capistrano General Plan Land Use Element identifies the
following major policies : (1) balancing land uses within the City to ensure that revenue
generation matches service provision responsibilities; (2) controlling and directing future
growth within the City so that the community character is preserved ; (3) protecting open
space areas to protect the public safety and the visual quality of the community; (4)
promoting economic development within the community; and (5) enhancing and
preserving the character of existing neighborhoods. The proposed General Plan Land
Use Designation is consistent with the intent of these policies.
The City Hall site is isolated from the core downtown area, and the
possible reuse of the site for residential purposes could create an economically viable
option to relocate City Hall to a more accessible location that would better serve the
community and generate revenue from the sale of land for development. The City Hall
site is located in an already urbanized area of San Juan Capistrano . The City Hall site
does not include protected open space areas; however, the site is located adjacent to
Descanso Park, and future residents of the area would benefit from having this
recreation/open space amenity available to them. Additionally, the site provides direct
access to bike and walking paths which allow for access to transit along Camino
Capistrano (0.25 miles away) and a grocery store (0 .3 miles away). Allowing for housing
development on the City Hall would place housing in close proximity to existing
commercial and employment centers, thus allowing residents to shop and work near
where they live. Changing the land use designation to Very High Density Residential
Page 3 05-03-2016
would not affect any existing neighborhoods since all immediately adjacent properties
are not zoned for residential uses.
Moreover, the General Plan Amendment is in the public interest because
Government Code Section 65580 (d) states that California state legislature finds that
"local and state governments have a responsibility to use the powers vested in them to
facilitate the improvement and development of housing to make adequate provision for
the housing needs of all economic segments of the community." Cities demonstrate
their efforts to meet their provisions of housing for all economic segments of the
community through their Housing Elements. In the 2014 adopted Housing Element , the
City identified a site to be rezoned to Very High Density Residential that would meet the
state requirements for facilitating the development of housing. The site was later
determined to be unsuitable, but the need to provide housing for all economic segments
remains intact. Therefore, the General Plan Amendment to change the land use
designation of the 2.5-acre northernmost portion of 32400 Paseo Adelanto, Assessor
Parcel Number: 668-101-23 from 4.1 Quasi-Industrial to 2.6 Very High Density
Residential, and the update to the Housing Element to document the modification will
serve the public interest by facilitating development of housing for all economic
segments of the community .
NOW, THEREFORE, BE IT FURTHER RESOLVED, that the City Council
approve of General Plan Amendment (GPA 15-003) to change the Housing Element
Sites Inventory Table (Table 25) and Corresponding Details, incorporated herein as
Exhibit B, and to amend the General Plan Land Use Policy Map Amendment for the City
Hall site (a portion of APN: 668-101-10), incorporated herein as Exhibit C.
CUSTODIAN OF RECORDS: The documents and materials associated
with this Resolution that constitute the record of proceedings on which these findings
are based are located at San Juan Capistrano City Hall, 32400 Paseo Adelanto, San
Juan Capistrano, California 92675. The City Clerk is the custodian of the record of
proceedings.

1.1 CEQA REQUIREMENTS:
CEQA § 21000 of the California Public Resources Code provides as follows:
The Legislature finds and declares as follows:
a) The maintenance of a quality environment for the people of this state now and in the future is a
matter of statewide concern.
b) It is necessary to provide a high-quality environment that at all times is healthful and pleasing to
the senses and intellect of man .
c) There is a need to understand the relationship between the maintenance of high-quality
ecological systems and the general welfare of the people of the state, including their enjoyment of
the natural resources of the state.
d) The capacity of the environment is limited, and it is the intent of the Legislature that the
government of the state take immediate steps to identify any critical thresholds for the health and
safety of the people of the state and take all coordinated actions necessary to prevent such
thresholds being reached.
e) Every citizen has a responsibility to contribute to the preservation and enhancement of the
environment.
f) The interrelationship of policies and practices in the management of natural resources and waste
disposal requires systematic and concerted efforts by public and private interests to enhance
environmental quality and to control environmental pollution.
g) It is the intent of the Legislature that all agencies of the state government which regulate activities
of private individuals, corporations, and public agencies which are found to affect the quality of
the environment, shall regulate such activities so that major consideration is given to preventing
environmental damage, while providing a decent home and satisfying living environment for every
Californian.
EXHIBIT A
Initial Study/Environmental Checklist -2-City of San Juan Capistrano, California
A concise statement of legislative policy, with respect to public agency consideration of projects for
some form of approval, is found in CEQA § 21002, quoted below:
The Legislature finds and dec.lares that it is the policy of the state that public agencies should not
approve projects as proposed if there are feasible alternatives or feasible mitigation measures
available which would substantially lessen the significant environmental effects of such projects,
and that the procedures required by this division are intended to assist public agencies in
systematically identifying both the significant effects of proposed projects and the feasible
alternatives or feasible mitigation measures which will avoid or substantially lessen such
significant effects . The Legislature further finds and declares that in the event specific economic,
social, or other conditions make infeasible such project alternatives or such mitigation measures,
individual projects may be approved in spite of one or more significant effects thereof.
The City has determined that preparation of an Addendum to the 2014-2021 Housing Element
Mitigated Negative Declaration pursuant to CEQA Guidelines section 15164 (Addendum to an EIR or
Negative Declaration) is the required method for achieving CEQA compliance for the revisions to the
2014-2021 Housing Element.
Pursuant to CEQA Guidelines Section 15164·
a) The lead agency or a responsible agency shall prepare an addendum to a previously certified EIR
if some changes or additions are necessary but none of the conditions described in Section
15162 calling for preparation of a subsequent EIR have occurred .
b) An addendum to an adopted negative declaration may be prepared if only minor technical
changes or additions are necessary or none of the conditions described in Section 15162 calling
for the preparation of a subsequent EIR or negative declaration have occurred .
c) An addendum need not be circulated for public review but can be included in or attached to the
final EIR or adopted negative declaration.
d) The decision-making body shall consider the addendum with the final EIR or adopted negative
declaration prior to making a decision on the project.
e) A brief explanation of the decision not to prepare a subsequent EIR pursuant to Section 15162
should be included in an addendum to an EIR , the lead agency's findings on the project, or
elsewhere in the record. The explanation must be supported by substant ial evidence.
CEQA authorizes a Lead or Responsible Agency to prepare an Addendum to a previously certified
EIR or adopted Mitigated Negative Declaration if some changes or additions are necessary to a
previously analyzed project and none of the conditions described in CEQA Guidelines Section 15162
requiring the preparation of a Subsequent EIR or CEQA Guidelines Section 15163 requiring the
preparation of a Supplement to an EIR are met.
Pursuant to CEQA Guidelines Section 15162:
a) When an EIR has been certified or negative declaration adopted for a project, no subsequent
EIR shall be prepared for that project unless the lead agency determines, on the basis of
substantial evidence in the light of the whole record, one or more of the following:
(1) Substantial changes are proposed in the project which will require major revisions of the
previous EIR or negative declaration due to the involvement of new significant
environmental effects or a substantial increase in the severity of previously identified
significant effects;
(2) Substantial changes occur with respect to the circumstances under which the project is
undertaken which will require major revisions of the previous EIR or negative declaration
due to the involvement of new significant environmental effects or a substantial increase
in the severity of previously identified significant effects; or
(3) New information of substantial importance, which was not known and could not have
been known with the exercise of reasonable diligence at the time the prev ious EIR was
Initial Study/Environmental Checklist -3-City of San Juan Capistrano, California
certified as complete or the negative declaration was adopted, shows any of the
following:
(A) The project will have one or more significant effects not discussed in the
previous EIR or negative declaration;
(B) Significant effects previously examined will be substantially more severe than
shown in the previous EIR;
(C) Mitigation measures or alternatives previously found not to be feasible would in
fact be feasible and would substantially reduce one or more significant effects
of the project, but the project proponents decline to adopt the mitigation
measure or alternative; or
-(D) Mitigation measures or alternatives which are considerably different from those
analyzed in the previous EIR would substantially reduce one or more
significant effects on the environment, but the project proponents decline to
adopt the mitigation measure or alternative .
b) If changes to a project or its circumstances occur or new information becomes available after
adoption of a negative declaration, the lead agency shall prepare a subsequent EIR if
required under subdivision (a). Otherwise, the lead agency shall determine whether to
prepare a subsequent negative declaration, an addendum, or no further documentation.
c) Once a project has been approved, the lead agency's role in project approval is completed,
unless further discretionary approval on that project is required . Information appearing after
an approval does not require reopening of that approval. If after the project is approved, any
of the conditions described in subdivision (a) occurs, a subsequent EIR or negative
declaration shall only be prepared by the public agency which grants the next discretionary
approval for the project, if any. In this situation no other responsible agency shall grant an
approval for the project until the subsequent EIR has been certified or subsequent negative
declaration adopted.
d) A subsequent EIR or subsequent negative declaration shall be given the same notice and
public review as required under Section 15087 or Section 15072. A subsequent EIR or
negative declaration shall state where the previous document is available and can be
reviewed.
Pursuant to CEQA Guidelines Section 15163:
a) The lead or responsible agency may choose to prepare a supplement to an EIR rather than a
subsequent EIR if:
(1) Any of the conditions described in Section 15162 would require the preparation of a
subsequentEIR,and
(2) Only minor additions or changes would be necessary to make the previous EIR
adequately apply to the project in the changed situation .
b) The supplement to the EIR need contain only the information necessary to make the previous
EIR adequate for the project as revised.
c) A supplement to an EIR shall be given the same kind of notice and public review as is given
to a draft EIR under Section 15087.
d) A supplement to an EIR may be circulated by itself without recirculating the previous draft or
final EIR.
e) When the agency decides whether to approve the project, the decision-making body shall
consider the previous EIR as revised by the supplemental EIR. A finding under Section
15091 shall be made for each significant effect shown in the previous EIR as revised.
The Amended 2014-2021 Housing Element project does not involve changes that will result in new or
increased environmental effects, new significant impacts, or the need for additional or increased
mitigation beyond those identified in the previously approved 2014-2021 Housing Element, thus, none
of the conditions identified in CEQA Guidelines Section 15162 or 15163 will be triggered by the
revised project. Therefore, in accordance with CEQA Guidelines Section 15164, the City, as the Lead
Agency, can amend the previously approved Mitigated Negative Declaration as an Addendum.

1.2 PROJECT BACKGROUND
Previously Approved 2014 -2021 Housing Element
The previously approved 2014-2021 Housing Element project included the following tasks:
1) General Plan Amendment: General Plan amendment to a) Adopt and implement the 2014-2021
Updated Housing Element, b) Rename the Affordable Family/Senior Housing residential land use
designation to Very High Density (VHD) residential land use, and c) Increase the maximum
residential density from 25 dwelling units per acre to 30 dwelling units per acre for the Very High
Density residential land use, and d) Amend two Opportunity sites from their existing land use to Very
High Density residential land use.
2) Code Amendment: Code amendment to a) Rename the Affordable Family/Senior Housing zoning
district to Very High Density (VHD) residential zoning district, b) Increase the maximum residential
density from 25 dwelling units per acre to 30 dwelling units per acre for the Very High Density
residential district, c) add additional zoning standards to the Very High Density Residential d) Update
the Density Bonus Program to comply with state law, and e) Rezone three Opportunity sites from
their existing zoning to Very High Density residential zoning district.
As part of the Housing Element adoption pr.ocess in 2014, City staff recommended General Plan
Amendments and rezoning for four potential housing sites to meet the City's Regional Housing Needs
Allocation (RHNA) requirements for the affordable housing allocations. Rezoning was proposed for
The Groves site, the former Ventanas site, the Camino Las Rablas site, and the Rancho San Juan
Apartments site. On January 21, 2014, the City Council adopted the 2014-2021 General Plan
Housing Element and approved a General Plan Amendment and the rezoning of two of the four
housing sites recommended to meet the City's Regional Housing Needs Assessment (RHNA)
allocation of 638 housing units. The Ventanas site and the Groves site were rezoned and provide for
approximately 278 units. The Rancho San Juan Apartments and Camino Las Ramblas were not
rezoned. Housing Element law stipulates that the City must ensure that its Housing Element Sites
Inventory can accommodate its share of the RHNA throughout the planning period (2014-2021 ).
Prop osed Amended 2014-2021 Housi ng Element
The proposed Amended 2014-2021 Housing Element project includes the following tasks:
1) General Plan Amendment: General Plan Amendment to: a) Amend the City Hall Site from its
existing land use (Quasi Industrial) to Very High Density Residential, and b) Amend the Housing
Element Sites Inventory to include the six new sites that will meet the RHNA.
2) Code Amendment: Municipal Code amendment to a) Amend the zoning for the City Hall
Opportunity Site from its existing zoning designation (Commercial Manufacturing) to Very High
Density Residential.
To comply with State Housing Element law and ensure continued certification of the Housing
Element, the Housing Element Sites Inventory will be updated to include six new sites: Oliva, The
Cove Estates, Pacifica San Juan, Don Juan Duplex Property, Hidden Creek Estates, and City Hall.
Five of the new sites (Oliva, The Cove Estates, Pacifica San Juan, Don Juan Duplex Property, and
Hidden Creek Estates) were included in the previous Housing Element (2008-2014); these require no
General Plan Land Use Amendments or rezoning . However, the City Hall site will require a General
Plan Land Use Designation Amendment and a Zoning Code Amendment. The City Hall site currently
has a General Plan Land Use Designation of Quasi-Industrial and is zoned Commercial
Manufacturing. For the City Hall Site to be included in the Sites Inventory for affordable housing, the
site will require a General Plan Amendment and zone change to Very High Density Residential. The
existing uses on this site include City Hall and a Public Works and Utility Department equipment
storage building. The proposed General Plan action does not apply to the portion of the site that
houses the City's Water Plant. In addition, redevelopment of the City Hall site could not occur until the
Initial Study/Environmental Checklist -5-City of San Juan Capistrano , California
City pursues the relocation of City Hall . With the addition of six sites to the Housing Element Sites
Inventory, the City will have adequate housing development capacity to meet the RHNA allocation.
1.3 SUMMARY OF ADDENDUM CONCLUSIONS
Section 8 of this Addendum describes in detail the differences between the previously approved
2014-2021 Housing Element and the proposed amended 2014-2021 Housing Element. Section 13 of
this Addendum describes the differences in environmental impacts and mitigation conclusions
between the previously approved 2014-2021 Housing Element and the amended 2014-2021 Housing
Element. A complete, verbatim listing of the impact and mitigation conclusions of the previously
approved 2014-2021 Housing Element for each environmental topic (such as Land Use and Relevant
Planning, Aesthetics/Light and Glare, Traffic and Circulation, etc.) is available for review at the City of
San Juan Capistrano Development Services Department, San Juan Capistrano City Hall, 32400
Paseo Adelanto, San Juan Capistrano, California 92675 (phone: 949-493-1171 ).
This Addendum concludes that the amended 2014-2021 Housing Element project would not
contribute to impacts to the extent that they would be greater than identified in the previously
approved 2014-2021 Housing Element. Consistent with Section 15162(a) of the CEQA Guidelines,
none of the impacts reiterated in this Addendum involve a new impact or more severe impact than
those identified in the previously approved 2014-2021 Housing Element.

8. PROJECT DESCRIPTION:
The proposed project consists of several tasks:
1) General Plan Amendment: General Plan Amendment to a) Amend the City Hall Site from its
existing land use (Quasi Industrial) to Very High Density Residential, and b) Amend the Housing
Element Opportunity Sites Inventory to include the six new sites that will meet the RHNA.
2) Code Amendment: Municipal Code amendment to a) Amend the zoning for the City Hall
Opportunity Site from its existing zoning designation (Commercial Manufacturing) to Very High
Density Residential.
To ensure continued certification of the Housing Element, the Housing Element Sites Inventory will be
updated to include six new sites: Oliva, The Cove Estates, Pacifica San Juan, Don Juan Duplex
Property, Hidden Creek Estates, and City Hall. Oliva, The Cove Estates, Pacifica San Juan, Don
Juan Duplex Property, and Hidden Creek Estates were included in the previous Housing Element
(2008-2014) and require no General Plan Land Use Amendments or rezoning. However, the City Hall
site will require a General Plan Land Use Designation Amendment and a zone change. The City Hall
site currently has a General Plan Land Use Designation of Quasi-Industrial and is zoned Commercial
Manufacturing. For the City Hall Site to be included in the Sites Inventory for affordable housing, the
site will require a General Plan Amendment and zone change to Very High Density Residential. The
existing uses on this site include City Hall and a Public Works and Utility Department equipment
storage building. The proposed General Plan action does not apply to the portion of the site that
houses the City's Water Plant. In addition, redevelopment of the City Hall site could not occur until the
City pursues the relocation of City Hall. With the addition of six sites to the Housing Element Sites
Inventory, the City will have adequate housing development capacity to meet the RHNA allocation.
1. Housing Element
Initial Study/Environmental Checklist -9-City of San Juan Capistrano, California
The Housing Element is one of the seven General Plan Elements mandated by the state of California
(Sections 65580 to 65589.8 of the California Government Code). California law requires that the
Housing Element consist of "identification and analysis of existing and projected housing needs and a
statement of goals, policies, quantified objectives, and scheduled programs for the preservation,
improvement, and development of housing." As required by state law, the City must plan for its share
of the region's new housing needs in the five state-defined income categories by identifying an
adequate supply of land zoned at appropriate densities to accommodate needs in each income
category. The Housing Element is a tool for decision-makers and the public use to understand and
meet housing needs in San Juan Capistrano. While the law does not require local governments to
actually construct housing to meet identified needs, it does require that the community address
housing needs in its discretionary planning actions such as creating opportunities for housing in the
land use plan and facilitating development through policies. To meet this goal, the Housing Element
identifies vacant or underdeveloped areas with existing or proposed residential General Plan Land
Use designations to accommodate the City's projected housing needs.
Housing Element Statutory Requirements
State law requires the Housing Element be updated at least every eight years, on a timeline
consistent with the Regional Transportation Plan, unless extended by the legislature. Article 1 0.6,
Sections 65580-65589.8, Chapter 3 of Division 1 of Title 7 of the Government Code sets forth the
legal requirements for a housing element and encourages the provision of affordable and decent
housing in suitable living environments for all communities to meet statewide goals. This 2014-2021
Housing Element update is a policy document for the City regarding its current and projected future
housing needs, as identified by the state department of Housing and Community Development
Department (HCD) and the Southern California Association of Governments (SCAG). The element
sets forth City goals, policies, and programs to address those identified needs.
Government Code Section 65583 requires that housing elements include the following main
components:
An assessment of housing needs (including the needs of special needs groups), analysis of
constraints to housing development, and an inventory of resources related to the meeting of
these needs .
A review of the previous Housing Element's goals, policies, programs, and objectives to ascertain
the effectiveness of each of these components,-as well as the overall effectiveness of the
programs in the previous Housing Element.
A statement of community goals, quantified objectives, and policies relative to the maintenance,
preservation, improvement, and development of housing.
Actions that the City is undertaking or intends to undertake, in implementing the policies set forth
in the Housing Element.
Housing Needs
The San Juan Capistrano 2014-2021 Housing Element profiles community demographics and
examines the related housing needs of various groups, including owners versus renters, lower-
income households, overcrowded households, elderly households, special needs groups, and
homeless persons, among others.
California housing element law requires that each city and county develop local housing programs
designed to meet their "fair share" of housing needs for all income groups, based on projected
population growth. The HCD Housing Policy Division develops the RHNA for each region of the state,
represented by councils of governments, which for San Juan Capistrano is SCAG. SCAG determines
the housing allocation for each city and county within its six-county jurisdiction. SCAG has assigned
San Juan Capistrano a housing allocation of 638 units for the 2014-2021 planning period. Table 1
(San Juan Capistrano 2014-2021 RHNA) identifies the total projected housing needs for the 2014-
2021 Housing Element.

State law requires that a community provide an adequate number of sites to allow for and facilitate
production of the city's regional share of housing . To determine whether a city has sufficient land to
accommodate its share of regional housing needs for all income groups, each city must identify
"adequate sites." Under state law (California Government Code Section 65583.c.1 ), adequate sites are
those with appropriate zoning and development standards, with services and facilities, needed to facilitate
and encourage the development of a variety of housing for all income levels. Land considered suitable for
residential development includes the following:
Vacant residentially zoned sites
Vacant non-residentially zoned sites that allow residential uses (such as mixed-use)
Underutilized residentially zoned sites that are capable of being developed at a higher density or
with greater intensity
Non-residential zoned sites that can be redeveloped for, and/or rezoned for, residential use (via
program actions)
Opportunity Sites
An important component of the Amended San Juan Capistrano 2014-2021 Housing Element is the
identification of sites and future housing development opportunities to meet the RHNA. Five sites from the
previously approved 2014-2021 Housing Element will be included in the Amended Opportunity Sites
Inventory including The Oaks, Calle Lorenzo, C. Romer Homestead, The Goves, and Ventanas. In
addition, the Amended Opportunity Sites inventory will include six new sites: Oliva, The Cove Estates,
Pacifica San Juan, Don Juan Duplex Property, Hidden Creek Estates, and City Hall. Five of the new sites
(Oliva, The Cove Estates, Pacifica San Juan, Don Juan Duplex Property, and Hidden Creek Estates)
were included in the previous Housing Element (2008-2014) and require no General Plan Land Use
Amendments or rezoning. However, the City Hall site will require a General Plan Land Use Designation
Amendment and a Zoning Code Amendment. The City Hall site currently has a General Plan Land Use
Designation of Quasi-Industrial and is zoned Commercial Manufacturing. For the City Hall Site to be
included in the Sites Inventory for affordable housing, the site will require a General Plan Amendment and
zone change to Very High Density Residential. As shown in Table 2 (Amended Opportunity Sites
Inventory), these parcels total approximately 311 .36 acres and could accommodate up to 772 units .

Initial Study/Environmental Checklist -13-City of San Juan Capistrano, California
The Opportunity sites (vacant and underutilized) serve as the basis for the environmental impact analysis
in this Initial Study. This is based on the fact that specific policies and direction within the proposed
Housing Element are guiding these parcels to be developed or recycled and therefore could lead to a
future physical change in the environment.
As the City of San Juan Capistrano is almost entirely built out, the majority of land identified in the
proposed Housing Element Sites Inventory focuses on vacant and underutilized land that could support
infill housing development. Approximately 311.36 acres have been identified in the inventory of potential
housing sites. The inventory of vacant land zoned specifically for residential use totals 14.9 acres (Sites
#4: The Groves, #5: Ventanas, #7: The Cove Estates, and #9: Don Juan Duplex Property). Sites #4 and
#5 were included in the previously approved 2014-2021 Housing Element and will require no land use or
zoning amendments. Sites #7 and #9 were included in the 2008-2014 Housing Element and will require
no land use or zoning amendments.
The inventory of underutilized land totals 296.46 acres (Sites #1, #2, #3, #6, #8, #1 0 and #11 ). Sites #1,
#2, and #3 were included in the previously approved 2014-2021 Housing Element and will require no land
use or zoning amendments. Sites #6, #8, and #1 0 were included in the 2008-2014 Housing Element and
will require no land use or zoning amendments. Site #11 (City Hall) will require a General Plan Land Use
Designation Amendment and a Zoning Code Amendment. Site #11 currently has a General Plan Land
Use Designation of Quasi-Industrial and is zoned Commercial Manufacturing. For the City Hall Site to be
included in the Sites Inventory for affordable housing, the site will require a General Plan Amendment and
zone change to Very High Density Residential.
Vacant Sites:
A total of 14.9 acres of vacant property has been identified as suitable for accommodating housing
construction. Using expected densities, an analysis of available vacant properties identifies the potential
for up to 290 new housing units within the incorporated City limits, as shown in Table 3 (Amended Vacant
Sites Land Inventory).

Constraints to Housing Production
The housing constraints section of the Housing Element analyzes barriers that may hinder the City's
ability to achieve its housing objectives or to obtain the necessary resources to assist in the production,
maintenance, and improvement of the overall housing stock. Governmental, market, infrastructure, and
environmental factors may constrain the provision of adequate and affordable housing. The City has
established a goal to minimize governmental constraints on housing production and affordability.
Housing Plan
The Housing Plan guides the development and preservation of a balanced inventory of housing to meet
the needs of present and future residents. To achieve this goal, the Housing Plan identifies long-term
housing goals and shorter-term policies to address the identified housing needs . The goals and policies
are then implemented through a series of housing programs. Programs identify specific actions the City
plans to undertake toward achieving each goal and policy. The following goals, policies, and
implementation programs represent the policy direction of the 2014-2021 Housing Element.
Housing Opportunities
Goal 1: Provide a broad range of housing opportunities with emphasis on providing housing which meets
the special needs of the community.
Policy 1.1: Consistent with the Land Use Element, provide a range of different housing types
and unit sizes for varying income ranges and lifestyles.

Initia l Study/EnvironmE;lntal Checklist ~15~ City of San Juan Capistrano, California
Policy 1.2: Continue the City's program of allowing the placement of mobile homes, factory built
housing on vacant residential parcels in single family zoning districts.
Policy 1.3: Encourage both the private and public sectors to produce or assist in the production
of housing with particular emphasis on housing affordable to persons with disabilities,
elderly, large families, female~headed households with children, and homeless.
Policy 1.4: Facilitate the development of second dwelling units on single~family parcels.
Program 1: Adequate Sites -The City has a Regional Housing Needs Assessment (RHNA) value
of 638 units for the 2014~2021 planning period. The inventory of residential sites yielded over 44
acres of vacant and developable land with the development capacity to yield over 800 new units.
The City will maintain an inventory of available sites for residential development and provide it to
prospective residential developers upon request.
Housing to Meet the Needs of a// Income Levels
Goal 2: To the maximum extent feasible, encourage and provide housing opportunities for persons of
lower and moderate incomes.
Policy 2.1: Encourage the development of affordable housing through the Density Bonus,
lnclusionary Housing, and City financial assistance programs.
Policy 2.2: Facilitate housing development that is affordable to extremely low~, lower-, and
moderate-income households by providing technical assistance, regulatory incentives
and concessions, expedited development review, and financial resources as funding
permits.
Policy 2.3: Continue to utilize federal and state subsidies, as well as City housing in~lieu fees in
a cost-efficient manner, to the fullest extent to meet the needs of lower-income
residents, including extremely low~income residents.
Policy 2.4: Implement -affordability agreements for all housing projects that receive financial
assistance from the City.
Policy 2.5: Encourage mixed use development on a case~by~case basis to allow for increased
housing opportunities.
Policy 2.6: Target City owned sites available for housing production for working families.
Policy 2. 7: Promote the development of affordable and special needs housing near transit
and/or "smart growth areas".
Policy 2.8: Encourage energy efficient design in new and rehabilitated development and in
existing housing units as a means to lowering housing costs.
Program 2: Mixed-Use Zoning -The City Council amended their policies to allow for the inclusion
of mixed-use development with the approval of the Historic Downtown Master Plan. To further
increase residential capacity in a mixed use context, the City will also explore additional locations
to implement mixed-use zoning provisions. Once additional mixed-use areas are identified, the
City will add zoning text designating the specific sites to allow residential uses as secondary
uses.
Program 3: lnclusionary Housing and ln~Lieu Fees-Developers of new residential developments
with two or more units are required to provide 10% of the development as affordable housing or
pay fees in-lieu of reserving affordable housing units for very low, low, and moderate income
Initial Study/Environmental Checklist -16-City of San Juan Capistrano, California
households. The City will continue to implement and evaluate this program and its impacts on
developments.
Program 4: Housing Choice Voucher Program -The City will continue to participate in the County
of Orange Housing Choice Voucher Rental Assistance Program, which provides rental assistance
to eligible very low and low-income households.
Program 5: Affordable Housing Funding -The City will facilitate or support the applications of
experienced housing developers and homeless service providers for financing to develop
affordable housing. The City will meet with potential affordable housing developers, provide site
information, assist in the entitlement process, and consider on a case-by-case basis other
incentives.
Program 6: Affordability Covenant for Accessory Units -The City has developed an approach to
allow for affordability covenants for new secondary dwelling units and will encourage interested
property owners to use this mechanism to expand affordable housing opportunities in the City.
Program 7: Mobile Home Park Rent Control Ordinance -The City's rent control ordinance
governs the maximum annual rent increases in all seven of the City's mobile home parks. The
City will continue to implement the ordinance to ensure that the City 's 1,266 mobile homes
continue to be the most affordable homeownership option within the City.
Program 8: Mortgage Credit Certificate Program (MCC)-The City will continue to participate in
and promote Mortgage Credit Certificates through the County of Orange. This program entitles
qualified first time homebuyers to take a federal income tax credit of 15 percent of the interest
paid on the mortgage. The City will increase awareness of the MCC program by providing
information on the City's website. Flyers and brochures will also be made available to residents at
key public locations.
Removal of Governmental Constraints
Goal 3: Reduce or remove governmental constraints to the development, improvement, and maintenance
of housing where feasible and legally permissible.
Policy 3.1: Periodically review City regulations, ordinances, permitting processes, and residential
fees to ensure that they do not constrain housing development and are consistent
with state law.
Policy 3.2: Continue cooperative agreements, as appropriate, with state, County and other
agencies, so that community housing needs are met to the greatest degree possible .
Policy 3.3: Offer financial and/or regulatory incentives, where feasible, to offset or reduce the
costs of developing quality housing affordable to a wide range of households .
Policy 3.4: Accommodate housing needs for extremely low-income households and special
needs persons in the City's development regulations.
Program 9: Reasonable Accommodation Procedure -The Fair Housing Act, as amended in
1988, requires that cities and counties provide reasonable accommodation to rules, policies,
practices and procedures where such accommodation may be necessary to provide individuals
with disabilities equal housing opportunities . The City will create a process for making requests
for reasonable accommodation to land use and zoning decisions and procedures regulating the
siting, funding, development and use of housing for people with disabilities. Information will be
provided to residents on reasonable accommodation procedures via public counters and the City
website.
Initial Study/Environmental Checklist -17-City of San Juan Capistrano, California
Program 10: Transitional and Supportive Housing-Transitional and supportive housing units are
allowed in the City based on the type and character of development. Transitional housing
provides longer term housing (up to two years), coupled with supportive services such as job
training and counseling to individuals and families who are transitioning from homelessness to
permanent housing. To reflect state law, the zoning code will explicitly address transitional
housing and supportive housing. Consistent with state law, transitional and supportive housing
that is provided in single-, two-, or multi-family dwelling units, group residential, residential care
facilities, or boarding house uses will be permitted, conditionally permitted or prohibited in the
same manner as the other single-, two-or multi-family dwelling units, group residential, residential
care facilities, or boarding house uses.
Conserve, Preserve, and Improve the Housing Stock
Goal 4: Create and maintain decent housing and a suitable living environment for all households in the
community.

2. Code Amendments
The following Code Amendments were included in the previously approved 2014-2021 Housing Element:
• Amendments to Municipal Code Sections 9-3.301 et al. of the Municipal Code regarding a name
change from Affordable Family I Senior Housing to Very High Density Residential, increase in
residential density from 25 dwelling units per acre to 30 dwelling units per acre, and add
additional zoning standards to the Very High Density Residential regarding amenities.
The 2014-2021 Housing Element Addendum includes the following Code Amendment:
• Municipal Code amendment to a) Amend the zoning for the City Hall Opportunity Site from its
existing zoning designation (Commercial Manufacturing) to Very High Density Residential.
9. SURROUNDING LAND USE(S) & PROJECT SETTING:
San Juan Capistrano is located in a coastal valley one mile from the ocean and is divided by Interstate 5
freeway that runs north and south through the City. Located in southern Orange County, San Juan
Capistrano is bounded by the cities of Mission Viejo to the north, San Clemente to the southeast , Dana
Point to the southwest, unincorporated Orange County to the east, and Laguna Niguel to the west. The
City's planning area encompasses approximately 14 square miles. San Juan Capistrano is approximately
90 percent built out , with limited vacant land available for development. With more than 600 feet of
vertical relief, the City's terrain consists primarily of gently to steeply containing deep cut canyons and
gullies rolling hills.
The Opportunity Sites identified in the Housing Element have specific surrounding land uses that must be
noted because these conditions serve as the baseline for environmental analysis in this Initial Study. The
existing surrounding land uses are summarized in Table 5 (Amended Opportunity Sites Surrounding Land
Uses).

13. SUMMARY OF ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The environmental
factors checked below would be potentially affected by this project, involving at least one impact that
is a "Potentially Significant Impact" as indicated by the checklist on the following pages:
Aesthetics D Agricultural Resources D Air Quality
Biological Resources D Cultural Resources D Geology & Soils
Hazards & Hazardous Mats. D Hydrology & Water Quality D Land Use & Planning
Mineral Resources 0 Noise D Population & Housing
Public Services D Recreation D Transportation & Traffic
Utilities & Service Systems D Mandatory Findings of Significance
14. DETERMINATION. (To be completed by lead agency) Based on this initial evaluation:
D I find that the proposed project COULD NOT have a significant effect on the environment,
and a NEGATIVE DECLARATION will be prepared.
D I find that although the proposed project could have a significant effect on the environment,
there will not be a significant effect in this case because revisions in the project have been made
by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be
prepared.
0 I find that the proposed project MAY have a significant effect on the environment, and an
ENVIRONMENTAL IMPACT REPORT is required .
0 I find that the proposed project MAY have a "potentially significant impact" or "potentially
l?ignificant unless mitigated" impact on the environment, but at least one effect 1) has been
adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has
been addressed by mitigation measures based on the earlier analysis as describe d on attached
sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects
that remain to be addressed.
I find that although the proposed project could have a significant effect on the environment,
because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or
NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or
mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or
mitigation measures that are imposed upon the proposed project, nothing further is required.
15. ENVIRONMENTAL ADMINISTRATOR DETERMINATION (Section 9-2.201 of SJC Municipal
Code): The initial study for this project has been reviewed and the environmental determination is
hereby approved:
David Contreras, Acting Assist nt Development Services Director
Environmental Administrator
16. ENVIRONMENTAL CHECKLIST
This section analyzes the potential environmental impacts which may result from the proposed
project. For the evaluation of potential impacts, the quest ions in the Initial Study Checklist (Section 2)
are stated and answers are provided according to the analysis undertaken as part of the Initial Study.
The analysis considers the project's short-term impacts (construction-related), and its operational or
day-to-day impacts. For each question, the following should be provided:
Initial Study/Environmental Checklist -28-City of San Juan Capistrano, California
1) A brief explanation is required for all answers except "No Impact" answers that are adequately
supported by the information sources a lead agency cites in the parentheses following each
question. A "No Impact" answer is adequately supported if the referenced information sources
show that the impact simply does not apply to projects like the one involved (e.g., the project falls
outside a fault rupture zone). A "No Impact" answer should be explained where it is based on
project-specific factors as well as general standards (e.g., the project will not expose sensitive
receptors to pollutants, based on a project-specific screening analysis).
2) All answers must take account of the whole action involved, including off-site as well as on-site,
cumulative as well as project-level, indirect as well as direct, and construction as well as
operational impacts.
3) Once the City has determined that a particular physical impact may occur, then the checklist
answers must indicate whether the impact is potentially significant, less than significant with
mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is
substantial evidence that an effect may be significant. If there are one or more "Potentially
Significant Impact" entries when the determination is made, an EIR is required.
4) "Negative Declaration: Less Than Significant With Mitigation Incorporated" applies where the
incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to
a "Less Than Significant Impact." The lead agency must describe the mitigation measures, and
briefly explain how they reduce the effect to a less than significant level (mitigation measures
from "Earlier Analyses," as described in (5) below, may be cross-referenced).
5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA
process, an effect has been adequately analyzed in an earlier EIR or negative declaration.
Section 15063(c)(3)(D). In this case, a brief discussion should identify the following:
a) Earlier Analysis Used. Identify and state where they are available for review.
b) Impacts Adequately Addressed. Identify which effects from the above checklist were
within the scope of and adequately analyzed in an earlier document pursuant to applicable
legal standards, and state whether such effects were addressed by mitigation measures
based on the earlier analysis.
c) Mitigation Measures. For effects that are "Less than Significant with Mitigation
Measures Incorporated," describe the mitigation measures which were incorporated or
refined from the earlier document and the extent to which they address site-specific
conditions for the project.
6) Incorporate into the checklist references to information sources for potential impacts (e.g.,
general plans, zoning ordinances). Reference to a previously prepared or outside document
should, where appropriate, include a reference to the page or pages where the statement is
substantiated.
7) Include a source list and list of individuals contacted or consulted.
8) This form is consistent with the California Environmental Quality Act (CEQA) Guidelines and
all Initial Studies performed on projects within the city must use this format.
9) The explanation of each issue should identify, a) the significance criteria or threshold, if any,
used to evaluate each question; and b) the mitigation measure identified, if any, to reduce the
impact to less than significance.

16.1 AESTHETICS. Would the project:
a . Have a substantial adverse effect on a scenic vista? 0 D [gJ 0
b. Substantially damage scenic resources, including, but not limited to
trees, rock outcroppings, and historic building along a State-D D 0 ~
designated scenic highway?
c . Substantially degrade the existing visual character or quality of the 0 0 ~ 0 site and its surroundings?
d . Create a new source of substantial light or glare which would D D ~ D adversely affect day or nighttime views in the area?
a) Have a substantial adverse effect on a scenic vista? Less than Significant Impact. Previously
Approved 2014-2021 Housing Element Initial Study Conclusion: Scenic vistas can be impacted by
development in two ways. First, a structure may be constructed that blocks the view of a vista. Second,
the vista itself may be altered (i.e., development on a scenic hillside). Features identified by the
community as having aesthetic value worth protecting and promoting include: the "small-village, rural
atmosphere"; extensive open spaces; the natural environment; the ridgelines ; the historical character of
the co mm unity; and the hi g h qua lity, unobtrusi ve design of the various public and private physical
ele me nts that make up the human environ men t.1 The proposed project would result in the adoption and
implementation of housing policies that could encourage new housing production. However, much of San
Juan Capistrano is developed, and any new development would likely occur on previously developed
sites . Furthermore, the Opportunity Sites are all within a fully urbanized area visually dominated by
residential and commercial land uses. Development projects in the City are subject to review and
approval by the Development Services Director, Planning Commission , and City Council. The Council
holds public hearings and applies conditions to entitlements to ensure that community design elements of
a project implement General Plan policies and are compatible with the character of the immediate
surrounding area . Although new development on the Opportunity Sites may result in higher densities,
implementation of existing General Plan policies, would result in impacts to scenic vistas that will be less
than significant.
General Plan Goals & Policies
Conservation & Open Space Goal 5: Shape and guide development in order to achieve efficient growth
and maintain community scale and identity.
Policy 5.2: Ensure that new development integrates and preserves areas designated for scenic,
historic, conservation, or public safety reasons.
Policy 5.3 : Ensure that no buildings will encroach upon any ridgeline designated for preservation.
Communilv Design Goal 3: Preserve and enhance natural features.
Policy 3.1 : Limit development of important natural characteristics such as ridgelines, unique hillside
features, and creeks.
Policy 3.3: Preserve and enhance scenic transportation corridors, including Interstate 5 and the
railroad.
Policy 3.4 : Preserve important viewsheds .
Initial Study/Environmental Checklist -30-City of San Juan Capistrano, California
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in a substantially more severe impact on a scenic vista than the previously
approved 2014-2021 Housing Element. As with the previously approved 2014-2021 Housing Element, the
Amended 2014-2021 Housing Element would result in the adoption and implementation of housing
policies that encourage new housing production . However, as mentioned in the previously approved
2014-2021 Housing Element Initial Study, much of San Juan Capistrano is developed, and any new
development would likely occur on previously developed sites. Furthermore, the new Opportunity Sites
are all within a fully urbanized area visually dominated by residential and commercial land uses.
Development projects in the City are subject to review and approval by the Development Services
Director, Planning Commission , and/or City Council. The City holds public hearings and applies
conditions to entitlements to ensure that community design elements of a project implement General Plan
policies and are compatible with the massing and height of the immediate surrounding area . Although
development on the new Opportunity Sites may result in higher densities, implementation of existing
General Plan policies would result in impacts to scenic vistas that will be less than significant. No new
impacts will occur.
b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and
historic buildings along a state scenic highway? No Impact. Previously Approved 2014-2021 Housing
Element Initial Study Conclusion: No designated state scenic highways are located within the City;
however, the California Scenic Highway Mapping System identified state Highway 74 as being eligible for
the state scenic hi ghway designation. State Highway 74 is not offici ally desi gnated as a state scenic
highway. Thus , no impact to scenic resources visible from a state scen ic hi ghwa y will occur.2
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in a substantially more severe impact on a state scenic highway than the
previously approved 2014-2021 Housing Element. As mentioned in the previously approved 2014-2021
Housing Element Initial Study, no designated state scenic highways are located within the City.
Furthermore, there are no scenic resources located on any of the Opportunity Sites. Thus, no new
impacts will occur.
c) Substantially degrade the existing visual character or quality of the site and its surroundings? Less
than Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion:
Implementation of the proposed project could result in a significant impact if it resulted in substantial
degradation of the existing visual character or quality of the site and its surround ings. Degradation of
visual character or quality is defined by substantial changes to the existing site appearance through
construction of structures such that they are poorly designed or conflict with the site's existing
surroundings. In order to preserve important community design features, the City has identified design
factors that should be considered when designing new development. Design factors important to
community design include : the building materials used in construction; building placement; height and
mass; the scale and form of already developed areas and their relationship to existing open spaces; the
design an d placement of other st ru ctures (s igns , roads, utility towers, etc .); and the treatment of hi lls ides
to form buil dable sites.3 Future ho usi ng deveiop ment could change th e on-and off-s ite visual chara cter of
the area in which it is constructed. Development of the Opportunity Sites could potentially change vacant
or already developed land to residential development. The proposed General Plan amendments and zone
changes associated with the Opportunity Sites do not propose any specific development proposals or
infrastructure construction . Therefore, these amendments will not result in any impacts that were not
addressed in the General Plan EIR. The General Plan addresses the conservation and enhancement of
the visual quality of San Juan Capistrano's environment via the following General Plan goals, policies and
design criteria.
General Plan Policies
Land Use Goal 2: Control and direct future growth within the City to preserve the rural and village-like
character of the community.
Policy 2.2: Assure that new development is consistent and compatible with the existing character of
Initial Study/Environmental Checklist -31-City of San Juan Capistrano. California
the City.
Land Use Goal 7: Enhance and maintain the character of neighborhoods.
Policy 7.1 : Preserve and enhance the quality of San Juan Capistrano neighborhoods by avoiding or
abating the intrusion of non-conforming buildings and uses.
Policy 7.2: Ensure that new development is compatible with the physical characteristics of its site,
surrounding land uses, and available public infrastructure.
Community Design Goal1 : Encourage and preserve a sense of place.
Policy 1.2: Encourage high-quality and human scale design in development and maintain the
character of the City.
Community Design Goal 2: Preserve the historic character of the community.
Policy 2.1: Encourage development which complements the City's traditional, historic character
through site design, architecture, and landscaping.
General Community Design Criteria 4
• Compatibility of building materials with the natural and existing human environment;
• Use of low building profiles;
• Discourage strip commercial development along arterial streets;
• Use of visually pleasing roof materials, especially for buildings in the valley areas visible from
surrounding hillsides;
• Use of open space to distinguish and separate different types of land use;
• Discouragement of large, sterile expanses of uses such as large parking lots or storage yards;
• Use of landscaping;
• Sensitive treatment of the natural topography, including ridgelines;
• Integration of pedestrian and bicycle trails into the open space network;
• Inclusion of energy conservation me~sures in new project design;
• Use of appropriate spaces or screening buffers between conflicting uses; and,
• Sign controls.
Adherence to the existing General Plan policies and design guidelines would result in a less than
significant impact on the visual character and quality of the City related to future housing constructed
pursuant to the Housing Element.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in a substantially more severe impact on existing visual character than the
previously approved 2014-2021 Housing Element. The proposed General Plan amendment and zone
change associated with new Opportunity Site #11 does not propose any specific development proposals
or infrastructure construction. Therefore, these amendments will not result in any impacts that were not
addressed in the General Plan EIR. The General Plan addresses the conservation and enhancement of
the visual quality of San Juan Capistrano 's environment through the General Plan goals, policies, and
design criteria listed herein. Adheren ce to the existing General Plan policies and design gui deli nes would
result in a less than significant impact on the v isual character and quality of the City rel ate d to future
housing constructed pursuant to the Housing Element. Thus , no new impacts will occur.
d) Create a new source of substantia/light or glare which would adversely affect day or nighttime views in
the area? Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study
Conclusion: Future housing development would result in new sources of lighting. Future housing
development would be required to adhere to the Zoning Code through the development review process.
The Zoning Cod e requires that all li ghtin g use shielded lum inaries with glare control to prevent light
spillover onto adjacent areas. 5 Addition all y, the City has lighting design criteria which limit lighti ng in
Initial Study/Environmental Checklist -32-City of San Juan Capistrano, California
hillside residential areas.6 Compliance with existing City practices, procedures, and policies for lighting
will ensure that lighting and glare impacts associated with potential new development are less than
significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in a substantially more severe Impact to light and glare than the previously
approved 2014-2021 Housing Element. As mentioned in the previously approved 2014-2021 Housing
Element Initial Study, future housing development would result in new sources of lighting. Future housing
development would be required to adhere to the Zoning Code through the development review process.
Compliance with existing City practices, procedures, and policies for lighting as mentioned in the
previously approved 2014-2021 Housing Element Initial Study will ensure that lighting and glare impacts
associated with potential new development are less than significant. No new impacts will occur.

a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as
shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the
California Resources Agency, to non-agricultural use? No Impact. Previously Approved 2014-2021
Housing Element Initial Study Conclusion: The map of Important Farmland in California (201 0) prepared
by the Department of Conservation identifies several areas within San Juan Capistrano that are
designated as Unique Farmland and Farmland of Statewide Importance; however, the majority of the City
is designated as urban and built-up land. San Juan Capistrano has historically been an agricultural
community with its valley producing a wide variety of crops. Therefore, the General Plan identifies land
designated as Agri-Business which provides for the production and sale of agricultural crops. The Zoning
Code also includes a Farm Market (FM) District and a Residential/Agriculture District. The Opportunity
Sites are not located within an area designated as Unique Farmland or Farmland of Statewide
Importance and are not designated as agricultural by the General Plan or Zoning Code. Therefore, there
will be no conversion of Prime Farmland , Unique Farmland, and Farmland of Statewide Importance to a
non-agricultural use as a result of this project. No impact will occur.7 8 9
2014-2021 Housing Element Initial Study Addendum Conclusion : The Amended 2014-2021 Housing
Element will not result in a substantially more severe impact to Prime Farmland, Unique Farmland,
Farmland of Statewide Importance than the previously approved 2014-2021 Housing Element. The new
Opportunity Sites are not located within an area designated as Unique Farmland or Farmland of
Statewide Importance and are not designated as agricultural by the General Plan or Zoning Code.
Therefore, there will be no conversion of Prime Farmland, Unique Farmland, and Farmland of Statewide
Importance to a non-agricultural use as a result of the 2014-2021 Housing Element Initial Study
Addendum. No new impacts will occur.
b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? No Impact. Previously
Approved 2014-2021 Housing Element Initial Study Conclusion : The California Department of
Conservation indicates that two Williamson Act contracts are active in San Juan Capistrano. The Zoning
Code includes a Farm Market (FM) District and a Residential/Agriculture District. The Opportunity Sites
are not located within an area under an active William Act Contract and are not located in an area
designated as agricultural by the Zoning Code. Therefore, there will be no conflict with existing zoning for

General Plan Policies
Consetvation & Open Space Goa/ 3: Preserve existing agricultural activity.
Policy 3.1 : Implement economic programs that promote the long-term viability of designated
agricultural parcels within the City.
Policy 3.2: Reduce the negative impacts resulting from urban uses and neighboring agricultural uses
in close proximity.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in a substantially more severe impact to existing zoning for agricultural use or a
Williamson Act contract than the previously approved 2014-2021 Housing Element. The new Opportunity
Sites are not located within an area under an active William Act Contract and are not located in an area
designated as agricultural by the Zoning Code . Therefore, there will be no conflict with existing zoning for
agricultural use or a Williamson Act contract. Furthermore, adherence to the General Plan policies will

Approved 2014-2021 Housing Element Initial Study Conclusion: Public Resources Code Section
12220(g) identifies forest land as land that can support 1 0-percent native tree cover of any species,
including hardwoods, under natural conditions, and that allows for management of one or more forest
resources, including timber, aesthetics, fish and wildlife, biodiversity, water quality, recreation , and other
public benefits . No properties in San Juan Capistrano are zoned for forest land, timberland, or timberland
production. Furthermore, the California Department of Forestry and Fire Protection describes the land
cover in the City as mostly urban with some rangeland shrubs and herbaceous vegetation.11 No impacts
to forest land or timberland will occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in a substantially more severe impact to property zoned for forest land, timberland,
or timberland production than the previously approved 2014-2021 Housing Element. As mentioned in the
previously approved 2014-2021 Housing Element Initial Study, no properties in San Juan Capistrano are
zoned for forest land, timberland, or timberland production. Furthermore, the California Department of
Forestry and Fire Protection describes the land cover in the City as mostly urban with some rangeland
shrubs and herbaceous vegetation . Thus, no new impacts will occur .
d) Results in the loss of forest land or conversion of forest land to non-forest use? No Impact. Previously
Approved 2014-2021 /-lousing Element In itia l Study Conclusion: Due to the urban ch aracter of San Juan
Capistra no, there is no forest land .12 Therefor e, there will be no loss of forest land or conversion of forest
land as a result of the implementation of the proposed Housing Element. No impact will occur.
2014-2021 Housing Element Initial Study Addendum Conclusion : The Amended 2014-2021 Housing
Element will not result in a substantially more severe impact to forest land than the previously approved
2014-2021 Housing Element. As mentioned in the previously approved 2014-2021 Housing Element
Initial Study, there is no forest land due to the urban character of San Juan Capistrano. Therefore, there
will be no loss of forest land or conversion of forest land as a result of the implementation of the Amended
Housing Element. Thus, no new impacts will occur.
e) Involve other changes in the existing environment which, due to their location or nature, could result in
conversion of Farmland, to non-agricultural use or conversion of forest land to non-forest use? No
Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion: The City does
contain sites zoned for agriculture . However, none of the Opportunity Sites are located on land zoned as

16.3 AIR QUALITY. Would the project:
a. Conflict with or obstruct implementation of the applicable air quality D D D [g) plan?
b. Violate an air quality standard or contribute to an existing or 0 0 [gJ 0 projected air quality violation?
c. Result in a cumulatively considerable net increase of any criteria
pollutant for which the project region is non-attainment under the
applicable federal or state ambient air quality standard (including 0 D 18:1 0
releasing emissions which exceed quantitative thresholds for ozone
precursors)?
d. Expose sensitive receptors to substantial pollutant concentrations? 0 D 18:1 0
e. Create objectionable odors affecting a substantial number of 0 0 [gJ [J people?
a) Conflict with or obstruct implementation of the applicable air quality plan? No Impact. Previously
Approved 2014-2021 Housing Element Initial Study Conclusion: The City is located within the South
Coast Air Basin (Basin) under the jurisdiction of the South Coast Air Quality Management District
(SCAQMD). SCAQMD and SCAG are responsible for formulating and implementing the Air Quality
Management Plan (AQMP) for the Basin. The AQMP is a series of plans adopted for the purpose of
reaching short-and long-term goals for those pollutants for which the Basin is designated as a
"nonattainment" area because it does not meet federal and/or state Ambient Air Quality Standards
(MQS). To determine consistency between the project and the AQMP, the project must comply with all
applicable SCAQMD rules and regulations, comply with all proposed or adopted control measures, and
must be consistent with the growth forecasts utilized in preparation of the Plan.
A significant impact could occur if the proposed project conflicts with or obstructs implementation of the
South Coast Air Basin 2012 AQMP. Conflicts and obstructions that hinder implementation of the AQMP
can delay efforts to meet attainment deadlines for criteria pollutants and maintaining existing compliance
with applicable air quality standards. Pursuant to the methodology provided in Chapter 12 of the 1993
SCAQMD CEQA Air Quality Handbook, consistency with the South Coast Air Basin 2012 AQMP is
affirmed when a project: 1) does not increase the frequency or severity of an air quality standards
violation or cause a new violation; and 2) is consistent with the growth assumptions in the AQMP.
Consistency review is presented below.
1. The project (including potential future housing development facilitated by the Housing Element
policy on proposed Opportunity Sites) proposes changes to Land Use and zoning designations as
well as an increase in density for the new Very High Density designation. The increase in density
allowed is greater than that analyzed in the General Plan EIR; therefore consistency analysis is
required.
2. The CEQA Air Quality Handbook indicates that consistency with AQMP growth assumptions must
be analyzed for new or amended General Plan elements, Specific Plans, and "significant projects."
Significant projects include airports, electrical generating facilities, petroleum and gas refineries,
designation of oil drilling districts, water ports, solid waste disposal sites, and off-shore drilling
facilities. The project consists of a General Plan amendment to update the proposed 2014-2021
Housing Element and amendments to Land Use and zoning designations; therefore consistency
analysis is required.
The Housing Element identifies eight opportunity sites for future residential development. The Opportunity
Initial Study/Environmental Checklist -37-City of San Juan Capistrano, California
Sites could result in approximately 807 new dwelling units and 2,340 new residents (807 dwelling units at
2.9 persons per household). SCAG provides population projection estimates in five-year increments from
2005 to 2035. According to the latest growth forecast (2012), SCAG estimates that the City would have a
population of 37,800 in 2035. SCAG growth projections are utilized as the basis for both the Regional
Transportation Plan (RTP) and the AQMP. Build-out of the General Plan would accommodate a
population of 38,520 persons, which would be higher than projected by SCAG, and thus provides
sufficient residential land uses to accommodate growth projections for the City. In addition, the proposed
Housing Element Opportunity Sites are projected to meet the City's allocated RHNA (638 units).
Therefore, by providing sites for housing sufficient to achieve the RHNA, the Housing Element is
contributing in the short term toward consistency with long-term growth projections and the 2012 AQMP.
The proposed Housing Element does propose densities higher than already permitted in the existing
General Plan and thus a General Plan and Zoning Code amendment will be required and the Density
Bonus Program will be updated to comply with state law. Implementation would not result in an increase
in population and households over that contemplated in the RTP and AQMP. These increases are within
the growth assumptions estimated by SCAG and therefore would not result in a conflict with or
obstruction of the AQMP. The proposed Housing Element and associated General Plan and Zoning Code
amendments do not propose or anticipate any specific development proposals or infrastructure
construction. Therefore, these amendments will not conflict with or obstruct the AQMP.
Based on the consistency analysis presented above, the proposed project will not conflict with the AQMP;
no impact will occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in a substantially more severe impacts regarding implementation of the applicable
air quality plan than the previously approved 2014-2021 Housing Element.
1. The project (including potential future housing development facilitated by the Housing Element
policy on proposed Opportunity Sites) proposes changes to Land Use and zoning designations;
therefore, consistency analysis is required.
2. The CEQA Air Quality Handbook indicates that consistency with AQMP growth assumptions must
be analyzed for new or amended General Plan elements, Specific Plans, and "significant
projects." Significant projects include airports, electrical generating facilities, petroleum and gas
refineries, designation of oil drilling districts, water ports, solid waste disposal sites , and off-shore
drilling facilities. The project consists of an addendum to the previously approved 2014-2021
Housing Element including a General Plan amendment to change Opportunity Site #11 (City Hall)
from Quasi-Industrial to Very High Density; therefore consistency analysis is required.
The 2014-2021 Housing Element Initial Study Addendum identifies eleven opportunity sites for future
residential development. The new Opportunity Sites could result in approximately 772 new dwelling units
and 2,238 new residents (772 dwelling units at 2.9 persons per household). SCAG provides population
projection estimates in five-year increments from 2005 to 2035. According to the latest growth forecast
(2012), SCAG estimates that the City would have a population of 37,800 in 2035. SCAG growth
projections are utilized as the basis for both the Regional Transportation Plan (RTP) and the AQMP.
Build-out of the General Plan would accommodate a population of 38,520 persons, which would be higher
than projected by SCAG, and thus provides sufficient residential land uses to accommodate growth
projections for the City. In addition, the amended Housing Element Opportunity Sites are projected to
meet the City's allocated RHNA (638 units). Therefore, by providing sites for housing sufficient to achieve
the RHNA, the Housing Element is contributing in the short term toward consistency with long-term
growth projections and the 2012 AQMP. The Amended Housing Element does propose densities higher
than already permitted in the existing General Plan and thus a General Plan and Zoning Code
amendment will be required. Implementation would not result in an increase in population and households
over that contemplated in the RTP and AQMP. These increases are within the growth assumptions
estimated by SCAG and therefore would not result in a conflict with or obstruction of the AQMP. The
Amended Housing Element and associated General Plan and Zoning Code amendment do not propose
or anticipate any specific development proposals or infrastructure construction. Therefore, these
Initial Study/Environmental Checklist -38-City of San Juan Capistrano, California
amendments will not conflict with or obstruct the AQMP. Based on the consistency analysis presented
above, the Amended 2014-2021 Housing Element will not conflict with the AQMP. Thus, no new impacts
will occur. ·
b) Violate any air quality standard or contribute substantially to an existing or projected air quality
violation? Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study
Conclusion: The proposed Housing Element and associated General Plan and Zoning Code
Amendments do not authorize any specific development project or land-altering activity that would involve
construction of new housing or any other development project. These amendments will not result in any
direct emissions that could contribute to an existing or potential violation of an air quality standard. The
2014-2021 Housing Element update would have no effect on rules and procedures governing
assessment or control of air pollutant emissions.
The proposed General Plan and Zoning Code Amendments will not directly result in construction of any
development or infrastructure; however, future residential development supported by the policies of the
updated Housing Element will result in short-term criteria pollutant emissions. Short-term criteria pollutant
emissions will occur during site preparation, grading, building construction, paving, and painting activities
associated with new development. Emissions will occur from use of equipment, worker, vendor, and
hauling trips. and disturbance of onsite soils (fugitive dust). Pursuant to CEQA, short-term, project-
specific, construction-related emissions will be analyzed as individual development proposals are
submitted. Mitigation will be applied, on a case-by-case basis where necessary. Such mitigation typically
includes requirements for use of low-VOC paints, installation of diesel particulate filters on older
construction equipment, and limitations on hauling distances and/or daily trips.
To address operational emissions from a typical development project, an air quality modeling analysis is
typically performed to determine if a project could regionally or locally cause a violation of any air quality
standard. Using the California Emissions Estimator Model (CaiEEMod), long-term emissions from the
planning area were modeled. Table 6 (Opportunity Sites Proposed Operational Daily Emissions in
lbs/day) summarizes the operational daily emissions that could occur from new development from the
identified opportunity sites. This reflects a worst-case scenario and does not account for uses currently
existing at the Opportunity Sites. There are no established or daily emissions thresholds for program-level
environmental analysis. Analysis of program-level air quality impacts are assessed through consistency
with the AQMP and identification of policies, regulations, and rules that will reduce pollutant emissions
from future development projects. The following emissions summary is provided solely for disclosure
purposes.

Based on the modeling data, total operational emissions from new development in the planning area
guided by the proposed Housing Element opportunity sites would slightly exceed the threshold for oxides
of nitrogen (NOX) during the winter months. This is a worst-case scenario and does not take into account
Initial Study/Environmental Checklist -39-City of San Juan Capistrano, California
the emissions from current uses on the site that would be removed. It should be noted that the daily
thresholds are not intended to be applied to the program-level; however, they do provide a baseline for
comparing incremental increases in emissions guided by the program.
Any future proposed development project would also be subject to SCAQMD's rules and regulations. The
San Juan Capistrano General Plan includes goals and policies that require coordination with other
agencies and the reduction in automobile emissions. With application of SCAQMD rules and the following
General Plan goals and policies, no new or more significant impacts relative to air quality standards would
result from implementation of General Plan Amendments than those analyzed in the General Plan EIR.
Because the proposed General Plan Amendments are consistent with the. AQMP (see Section 16.3.a)
and future development projects supported by the General Plan Amendments will be subject to
environmental review to ensure that daily criteria pollutant thresholds will not be exceeded, impacts will
be less than significant.

2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element would not violate any air quality standard or contribute substantially to an existing or projected air
quality violation beyond the previously approved 2014-2021 Housing Element. The 2014-2021 Housing
Element Addendum and associated General Plan and Zoning Code Amendments do not authorize any
specific development project or land-altering activity that would involve construction of new housing or
any other development project. These amendments will not result in any direct emissions that could
contribute to an existing or potential violation of an air quality standard. The 2014-2021 Housing Element

Any future proposed development project would also be subject to SCAQMD's rules and regulations . The
San Juan Capistrano General Plan includes goals and policies that require coordination with other
agencies and the reduction in automobile emissions. With application of SCAQMD rules and the following
General Plan goals and policies, no new or more significant impacts relative to air quality standards would
result from implementation of General Plan Amendments than those analyzed in the General Plan EIR.
Because the proposed General Plan Amendments are consistent with the AQMP (see Section 16 .3.a)
and future development projects supported by the General Plan Amendments will be subject to
environmental review to ensure that daily criteria pollutant thresholds will not be exceeded, impacts will
be less than significant. No new impacts will occur.
c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region
is non-attainment under an applicable federal or state ambient air quality standard (including releasing
emissions which exceed quantitative thresholds for ozone precursors)? Less than Significant Impact.
Previously Approved 2014-2021 Housing Element Initial Study Conclusion: The SCAQMD has prepared
an Air Quality Management Plan to set forth a comprehensive and integrated program that will lead the
Basin into compliance with the federal 24-hour PM2.5 air quality standard, and to provide an update to
the SCAQMD's commitments toward meeting the federal 8-hour ozone standards . The Basin is currently
in non-attainment for state and federal criteria pollutants ozone, nitrogen dioxide, and fine particulate
matter (PM2.5 and PM1 0).
New development facilitated by the Housing Element update will be required to comply with SCAQMD
rules and regulations aimed at reducing construction-related pollutant emissions, including fugitive dust
and other particulates, as well as organic compounds and other ozone precursors found in paints and
other coatings. Considering that the proposed General Plan and Zoning Code amendments are
consistent with the development projections of the San Juan Capistrano General Plan and the breadth of
existing standards and regulations, implementation of the proposed housing policies of the Housing
Element update would not change or otherwise interfere with the regional pollutant control strategies of
the AQMP. The project's impact on cumulative levels of regional ozone or particulates is therefore less
than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in cumulatively considerable net increases of any criteria pollutant beyond the
prev iously approved 2014-2021 Housing Element. As mentioned in the previously approved 2014-2021
Housing Element Initial Study, new development facilitated by the Amended Housing Element will be
required to comply with SCAQMD rules and regulations aimed at reducing construction-related pollutant
emissions, including fugitive dust and other particulates, as well as organic compounds and other ozone
precursors found in paints and other coatings. Considering that the proposed General Plan and Zoning
Code amendments are consistent with the development projections of the San Juan Capistrano General
Plan and the breadth of existing standards and regulations, implementation of the proposed housing
Initial Study/Environmental Checklist -42-City of San Juan Capistrano , California
policies of the Amended Housing Element would not change or otherwise interfere with the regional
pollutant control strategies of the AQMP. The Amended Housing Element's impact on cumulative levels of
regional ozone or particulates is therefore less than significant. No new impacts will occur.
d) Expose sensitive receptors to substantial pollutant concentrations? Less than Significant Impact.
Previously Approved 2014-2021 Housing Element Initial Study Conclusion: Common sensitive receptors
include children under age 14, the elderly over age 65, athletes, and people with cardiovascular and
chronic respiratory diseases . The project promotes development of housing that could likely
accommodate children and the elderly; however, adoption of the Housing Element update does not
authorize construction or redevelopment of any specific housing units . The proposed General Plan and
Zoning Code amendments do change residential land use designations by increasing the maximum
residential density to thirty dwelling units per acre . However, the proposed amendments do not propose
or anticipate any specific development proposals or infrastructure construction. Through its standard
development review process that includes review pursuant to CEQA statutes and guidelines, the City will
ensure that any future development projects developed pursuant to proposed General Plan policies and
programs provide adequate protection for residents from any local air pollution sources. Project impacts
on sensitive receptors would be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in the exposure of sensitive receptors to substantial pollutant concentrations
beyond the previously approved 2014-2021 Housing Element. As mentioned in the previously approved
2014-2021 Housing Element Initial Study, the project promotes development of housing that could likely
accommodate children and the elderly; however, adoption of the Amended Housing Element does not
authorize construction or redevelopment of any specific housing units. The proposed General Plan and

pursuant to CEQA statutes and guidelines, the City will ensure that any future development projects
developed pursuant to proposed General Plan policies and programs provide adequate protection for
residents from any local air pollution sources. Project impacts on sensitive receptors will be less than
significant. No new impacts will occur.
e) Create objectionable odors affecting a substantial number of people? Less than Significant Impact.
Previously Approved 2014-2021 Housing Element Initial Study Conclusion: Residential land uses typically
do not create objectionable odors . No new odor sources would result from adoption of the Housing
Element because it does not authorize construction of any specific new housing project or redevelopment
of existing housing . Furthermore, the General Plan Amendment would not authorize any relaxation or
elimination of current requirements for proper waste storage and disposal for new development projects.
Therefore, the potential for the project to create objectionable odors is considered less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not create objectionable odors beyond the previously approved 2014-2021 Housing Element.
As mentioned in the previously approved 2014-2021 Housing Element Initial Study , residential land uses
typically do not create objectionable odors . No new odor sources would result from the Amended Housing
Element because it does not authorize construction of any specific new housing project or redevelopment
of existing housing. Furthermore, the General Plan and zoning code amendments would not authorize
any relaxation or elimination of current requirements for proper waste storage and disposal for new
development projects. Therefore, the potential for the Amended Housing Element to create objectionable
odors is considered less than significant and no new impacts will occur.

with Mitigation Incorporated. Previously Approved 2014-2021 Housing Element Initial Study
Conclusion: When a species is proposed for listing as threatened or endangered under the Endangered
Species Act, areas essential to the species conservation must be considered. These areas are known as
"critical hab ita t". Opportunity Site #7 (Ventanas ) con tai ns areas identified by the U.S . Fish an d Wildlife
Serv ice as C ritical Habitat for the Endangered Ar royo Toad (Anaxyrus cali forn ic uss).13 Predation from
introduced aquatic species and the loss of habitat , coupled with habitat mod ifications due to the
establishment of nonnative plants and the manipulation of water levels in many central and southern
California streams and rivers led to the federal-listing of the Arroyo Toad as an Endangered Species in
1994. San Juan Creek traverses a portion of Opportunity Site #7 and is designated as a wetland by the
USFWS National Wetlands Inventory. Optimal breeding habitat for the toad consists of low-gradient
sections of slow-moving streams with shallow pools, nearby sandbars, and adjacent stream terraces .
Ad ult toads are often fo u nd on sandy alluvial terraces ad jacent to the stream that may be spar sely-to-
heavi ly vegetated with bru sh and trees.14 Alt hough a po rt ion of Site #7 is identified as ha ving critic al
habitat, there is evidence that the sites have been cleared and developed in the past. Little vegetation
exists on the site except for portions of the sites adjacent to the creek bed. The Federal Endangered
Species Act states that a critical habitat designation does not necessarily restrict further development.
Only activities that involve a Federal Permit, license , or funding, and are likely to destroy or adversely
modify the area of critical habitat will be affected. There is the potential for the development on the Site to
receive Federal Housing and Urban Development funds in the future for the construction of affordable
housing . If this funding occurs, the USFWS will coordinate with the Federal funding agency involved and,
where appropriate, require private or other landowners to amend their project or incorporate mitigation so
that the significant impacts to critical habitat. For projects not subject to Federal requirements, alteration

or removal of sensitive on-site habitat could result in significant impacts to the Arroyo toad due to a
reduction in habitat and/or harm due to development of the site. To ensure that future development on
Site # 7 does not substantially affect the Arroyo toad or its habitat, Mitigation Measure 81 has been
incorporated. Mitigation Measure 81 requires a general biological survey to be performed prior to
approval of entitlements to identify any on-site sensitive species and to assess the value of the existing
habitat in supporting sensitive species.
No construction projects are proposed as part of the 2014-2021 Housing Element Update, General Plan
Amendments, and Zoning Code Amendments. Any future development will be subject to individual CEQA
review that will include assessment of any potential impacts to sensitive species and their habitat. The
proposed project would, therefore, not have a substantial adverse effect on any species identified as a
candidate, sensitive, or special-status species in local or regional plans or by the California Department of
Fish and Game or U.S. Fish and Wildlife Service with implementation of existing standards and
incorporation of
Mitigation Measure B-1.
Mitigation Measure B-1
A biological resources assessment shall be prepared for any development proposal prior to approval of
entitlements located on any land within a Critical Habitat designation or identified in the General Plan
Environmental Impact Report as riparian habitat. This assessment shall identify the habitat types and
quality, identify species occurrence and distribution, determine the specific impacts to biological
resources and characterize the biological significance of those impacts, and define measures to avoid,
reduce or compensate for any significant impacts attributable to a proposed project. The reduction in
impacts may include a redesign of the project. The compensation may include creating and/or preserving
in perpetuity equivalent or better quality habitat at a minimum 1 :1 ratio, as will be determined through
project-specific analysis. The biological resources assessment shall be prepared by a qualified biologist
and submitted to the Development Services Director for review/approval in consultation with the biologist
and other as appropriate to the project. The biological resources assessment shall be included in the
CEQA compliance documentation for all such proposals.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not have a substantial adverse effect, either directly or through habitat modifications, on any
species identified as a candidate, sensitive, or special status species beyond the previously approved
2014-2021 Housing Element. As mentioned in the previously approved 2014-2021 Housing Element
Initial Study, Opportunity Site #7 (Ventanas) contains areas identified by the U.S. Fish and Wildlife
Service as Critical Habitat for the Endangered Arroyo Toad (Anaxyrus californicuss). In addition, a portion
of the site is designated as a wetland by the USFWS National Wetlands Inventory. Opportunity Site #7
(Ventanas) from the previously approved 2014-2021 Housing Element remains an Opportunity Site in the
Amended 2014-2021 Housing Element. However, Ventanas is now Opportunity Site #5. Mitigation
Measure B-1 will remain applicable to the Ventanas Opportunity Site.
Amended Opportunity Site #8 (Pacifica San Juan) is partially located within critical habitat for the Coastal
California gnatcatcher (Polioptila California). Thus, Mitigation Measure B-1 will be applicable to
Opportunity Site #8 (Pacifica San Juan). The General Plan Conservation and Open Space Element
includes Policy 2.1 that requires application of land use planning decisions and techniques in order to
reduce the impact of urban development on important ecological and biological resources. With
application of General Plan policies, impacts will be less than significant with mitigation incorporated and
no new impacts will occur.
General Plan Policies:
Conservation and Open Space Policy 2.1 Use proper land use planning to reduce the impact
of urban development on important ecological and
biological resources.
b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community
identified in local or regional plans, policies, regulations or by the California Department of Fish and
Initial Study/Environmental Checklist -45-City of San Juan Capistrano, California
Game (DFG) or U.S. Fish and Wildlife Service? Less than Significant with Mitigation Incorporated.
Previously Approved 2014-2021 Housing Element Initial Study Conclusion: The majority of San Juan
Capistrano is urbanized and previously developed, and has landscaping consisting of non-native,
ornamental plants. However, three creeks are located within San Juan Capistrano. Two of the Opportunity
Sites are adjacent to creeks. Trabuco Creek traverses the northwestern edge of the Site #5 and is
designated as a wetland by the USFWS National Wetlands Inventory. San Juan Creek traverses a portion
of Site #7 and is designated as a wetland by the USFWS National Wetlands Inventory.
According to the General Plan EIR, three plant communities exist within San Juan Capistrano that are
considered to be sensitive and contain sensitive wildlife: scrub, grasslands and riparian. Coastal sage
scrub describes a wide variety of low, scrubby native plant associations that occur on lowland bluffs and
hillsides from southern Oregon to Baja Califor nia , Mexico. Characteristic s~ecies of coastal sage scrub
include California sage brush and several species of sage and buckwheat.1 The coastal sage scrub is a
fragmented and dispersed community embedded within a mosaic of other vegetation communities. Sage
scrub occurs within pockets throughout the City that are sur rounded by grasslands in the southern and
western areas, but are isolated among development in the north-cen tral portion of the City.16 Significant
portions of the coastal sage scrub habitat are located within the Natural Community Conservation
permanent reserve system. Sage scrub is habitat for the U.S. Fish and Wildlife Service Threatened
California gnatcatcher, and thus also receives regulatory protection from the USFWS. Other sensitive
species supported by sage scrub expected to occur within the City include Chalcedon checkerspot,
Mormon metalmark, Acmon blue, southern California rufous-crowned sparrow, coastal cactus wren, Bell's
sage sparrow, San Diego horned lizard, San Diego banded gecko, orange-throated whiptail, coastal
whlptail, northern red diamond rattlesnake, pallid bat, Californ ia mastiff bat, northwestern San Diego
pocket mouse, San Diego desert woodrat , San Diego black-ta iled jackrabbit, and moun tain lion.17
Grasslands are present on a large portion of the remaining vacant land within the City. Local grasslands
are typically dominated by non-native grasses and forbs; however, pockets of grasslands containing
native bunchgrasses and annual wildflowers are considered to be sensitive. Sensitive species likely to
occur in grassland habitat include the California ringlet, rural/farmer skipper, San Diego horned lizard,
northern harrier, white-tailed kite, California horned lark, grasshopper sparrow, San Diego black-tailed
jackrabbit, and American badger.
Riparian habitat exists along the City's three major creeks: San Juan Creek, T-rabuco Creek and Oso
Creek. Species that are likely to be found within the City's riparian habitat include: least Bell's vireo,
yellow warbler, yellow breasted chat, downy woodpecker, coast range newt, western spadefoot toad,
southwestern arroyo toad, southwestern pond turtle, California legless lizard, two-striped garter snake,
San Diego ringneck snake, Cooper's hawk, red-shouldered hawk, tri-colored blackbird, western tiger
swallowtail, mourning cloak, and Lorquin's admiral.
Although portions of Sites #5 and #7 are designated wetlands with associated riparian habitat, there is
evidence that the sites have been cleared and developed in the past. No construction projects are
proposed as part of the 2014-2021 Housing Element Update, General Plan Amendments, and Zoning
Code Amendments. Any future development will be subject to individual CEQA review that will require
assessment of potential impacts to biological resources, including riparian habitat that could support
sensitive species. To ensure that future development on Site# 5 and Site# 7 does not substantially affect
sensitive riparian habitat, Mitigation Measure B-1 has been incorporated. Mitigation Measure B1 requires
a general biological survey to be performed prior to approval of entitlements to identify any on-site
sensitive species and to assess the value of the existing habitat in supporting sensitive species. Impacts
to riparian habitat will be less than significant with mitigation incorporated.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not have a substantial adverse effect on any riparian habitat or other sensitive natural
community beyond the previously approved 2014-2021 Housing Element. Sites #5 (The Groves) and #7
(Ventanas) from the previously approved 2014-2021 Housing Element Initial Study remain Opportunity
Sites in the Amended 2014-2021 Housing Element. However, The Groves is now Opportunity Site #4 and
Ventanas is now Opportunity Site #5. As mentioned in the previously approved 2014-2021 Housing
Element Initial Study, although portions of The Groves and Ventanas Opportunity Sites are designated
Initial Study/Environmental Checklist -46-City of San Juan Capistrano, California
wetlands with associated riparian habitat, there is evidence that the sites have been cleared and
developed in the past. No construction projects are proposed as part of the 2014-2021 Housing Element
Addendum. Any future development will be subject to individual CEQA review that will require
assessment of potential impacts to biological resources, including riparian habitat that could support
sensitive species. As mentioned in the previously approved 2014-2021 Housing Element Initial Study,
The Groves and Ventanas Opportunity Sites will be subject to Mitigation Measure B-1 which requires a
general biological survey to be performed prior to approval of entitlements to identify any on-site sensitive
species and to assess the value of the existing habitat in supporting sensitive species. Impacts to riparian
habitat will be less than significant with mitigation incorporated. No new impacts will occur.
c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the
Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal,
filling, hydrological interruption, or other means? Less than Significant Impact. Previously Approved
2014-2021 Housing Element Initial Study Conclusion: According to the Federal National Wetlands
Inventory, wetlands within San Juan Capistrano exist primarily along San Juan Creek, Trabuco Creek and
Oso Creek. Trabuco Creek traverses the eastern portion of Site #5 (The Groves) and is designated as a
wetland by the USFWS National Wetlands Inventory. San Juan Creek traverses the eastern portion of
Site #7 (Ventanas) and is designated as a wetland by the USFWS National Wetlands Inventory. Impacts
to Section 404 wetlands from potential future housing development constructed pursuant to the policies of
the proposed Housing Element could occur if future housing projects interrupt or otherwise alter on-site
wetlands.
Section 401 of the CWA requires an applicant to obtain certification for any activity that may result in a
discharge of a pollutant into waters of the United States. As a result, proposed fill in waters and wetlands
requires coordination with the appropriate State Regional Water Quality Control Board (RWQCB) that
administers Section 401 and provides certification. The RWQCB also plays a role in review of water
quality and wetland issues, including avoidance and minimization of impacts. Section 401 certification is
required prior to the issuance of a Section 404 permit, as discussed below.
Under Section 404 of the CWA the U.S. Army Corps of Engineers (ACOE) has jurisdiction over Wetlands
and Waters of the United States. Permitting of activities that could discharge fill or dredge materials or
otherwise adversely modify wetlands or other waters of the United States and associated habitat is
required. Permits authorized by ACOE under the Act typically involve mitigation to offset unavoidable
impacts on wetlands and other waters of the United States in a manner that achieves no net loss of
wetland acres or values.
The California Department of Fish and Wildlife (CDFW), through provisions of the Fish and Game Code
Sections 1600-1603, is empowered to issue agreements (Streambed Alteration Agreements) for projects
that would "divert or obstruct the natural flow of, or substantially change or use any material from the bed,
channel, or bank of, any river, stream, or lake, or deposit or dispose of debris, waste, or other material
containing crumbled, flaked, or ground pavement where it ·may pass into any river, stream, or lake" (Fish
and Game Code Section 1602[a]). Streams and rivers are defined by the presence of a channel bed,
banks, and intermittent flow. The limits of CDFW jurisdiction are also based on riparian habitat and may
include wetland areas that do not meet US Army Corps of Engineers (ACOE) criteria for soils and/or
hydrology (e.g., where riparian woodland canopy extends beyond the banks of a stream away from
frequently saturated soils).
Future housing development will be subject to environmental review pursuant to CEQA and the City's
local development review procedures. This includes assessment of biological resources. Any project
impacts streams or wetlands are subject to Federal Section 401 and/or 404 permitting and State Section
1600 stream alteration requirements. These regulations require identification and mapping of any wetland
resources and implementation of appropriate mitigation as discussed above to ensure no net loss of
wetland area or values. Implementation of existing regulations will ensure that impacts to wetlands are
less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not have a substantial adverse effect on any wetlands beyond the previously approved 2014-
Initial Study/Environmental Checklist -47-City of San Juan Capistrano California
2021 Housing Element. Sites #5 (The Groves) 'and #7 (Ventanas) from the previously approved 2014-
2021 Housing Element Initial Study remain Opportunity Sites in the Amended 2014-2021 Housing
Element. However, The Groves is now Opportunity Site #4 and Ventanas is now Opportunity Site #5. As
mentioned in the previously approved 2014-2021 Housing Element Initial Study, future housing
development will be subject to environmental review pursuant to CEQA and the City's local development
review procedures. This includes assessment of biological resources. Any project impacts streams or
wetlands are subject to Federal Section 401 and/or 404 permitting and State Section 1600 stream
alteration requirements. These regulations require identification and mapping of any wetland resources
and implementation of appropriate mitigation as discussed above to ensure no net loss of wetland area or
values. Implementation of existing regulations will ensure that impacts to wetlands are less than
significant. No new impacts will occur.
d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or
with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery
sites? Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study
Conclusion: Based on Natural Community Conservation Planning surveys, biologists believe that a
number of species, including the California gnatchatcher, coyote, fox, and others use the Trabuco and
Oso Creeks and adjacent lands as corridors for movement between the Coastal and Southern
Subregional NCCP open space areas. Despite alterations, San Juan Creek also provides connectivity
from eastern off-s ite habitat areas to the southern San Juan Capistrano grasslands and scrub areas.18
Trabuco Creek traverses the east side of Site #5 (The Groves). Future development would not be
authorized to disrupt the hydrologic function of any waterway pursuant to local, state, and federal laws
prohibiting loss or alteration of these resources; therefore, movement of wildlife and aquatic species
through local riparian corridors would not be substantially impacted by future housing development.
Impacts will be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not interfere substantially with the movement of any native resident or migratory fish or
wildlife species or with established native resident or migratory wildlife corridors, or impede the use of
native wildlife nursery sites beyond the previously approved 2014-2021 Housing Element. As mentioned
in the previously approved 2014-2021 Housing Element Initial Study, future development will not be
authorized to disrupt the hydrologic function of any waterway pursuant to local, state, and federal laws
prohibiting loss or alteration of these resources; therefore, movement of wildlife and aquatic species
through local riparian corridors will not be substantially impacted by future housing development. Impacts
will be less than significant and no new impacts will occur.
e) Conflict with any local policies or ordinances protecting biological resources, such as tree preservation
policy/ordinance? No Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion:
The San Juan Capistrano General Plan Conservation and Open Space Element contains policies
intended to protect biological resources. Implementation of the proposed Housing Element and land uses
changes would not authorize construction. Any future projects will be subject to individual CEQA review.
Adherence to the following General Plan policies will reduce impacts to biological resources.
General Plan Policies
Conservation & Open Space Policy 2.1: Use proper land use planning to reduce the impact of urban
development on important ecological and biological resources.
Conservation & Open Space Policy 2.2: Preserve important ecological and biological resources as open
space.
Conservation & Open Space Policy 2.3: Develop open space uses in an ecologically sensitive manner.
Conservation & Open Space Policy 2.4: Continue to designate the City as a bird sanctuary to preserve
and protect the populations of all migratory birds which serve as
a prime resource to the character and history of the community.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Initial Study/Environmental Checklist -48-City of San Juan Ca pistrano, California
Element will not conflict with any local policies or ordinances protecting biological resources, such as tree
preservation policy/ordinance beyond the previously approved 2014-2021 Housing Element. As
mentioned in the previously approved 2014-2021 Housing Element Initial Study, the San Juan Capistrano
General Plan Conservation and Open Space Element contains policies intended to protect biological
resources. Implementation of the proposed Housing Element and land uses changes would not authorize
construction. Any future projects will be subject to individual CEQA review. Adherence to the following
General Plan policies will reduce impacts to biological resources. No new impacts will occur.
f) Conflict with the provisions of an adopted Habitat Conservation Plan Natural Community Conservation
Plan, or other approved local, regional, or state habitat conservation plan? No Impact. Previously
Approved 2014-2021 Housing Element Initial Study Conclusion: San Juan Capistrano lies on the border
of both the Coastal and Southern Su bregions of the Oran ge Coun ty Natural Community Co nservation
Plan and Habitat Conservation Planni ng Area.19 The planni ng area for the NCCP covers 208,000 ac res
and the Rese rve System Obli gation covers 37,378 acres . The City does not contain Reserve System
acreage, thus, the City is not a signatory to the Implem enta tion Agreement f or the sub-region.20 T herefore
the project would not result in conservation planning impacts.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not cause conflicts with the provisions of an adopted Habitat Conservation Plan, Natural
Community Conservation Plan, or other approved local, regional, or state habitat conservation plan
beyond the previously approved 2014-2021 Housing Element. As mentioned in the previously approved
2014-2021 Housing Element Initial Study, San Juan Capistrano lies on the border of both the Coastal and
Southern Subregions of the Orange County Natural Community Conservation Plan and Habitat
Conservation Planning Area. However, the City does not contain Reserve System acreage, thus, the City
is not a signatory to the Implementation Agreement for the sub-region. Therefore the Amended Housing
Element would not result in conservation planning impacts. No new impacts will occur.

d. Disturb any human remains, including those interred outside of 0 [gl 0 0 formal cemeteries?
a) Cause a substantial adverse change in the significance of a historical resource as defined in ' 15064.5
of CEQA? No Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion : The
General Plan Cultural Resources Element identifies areas where historic buildings and structures occur.
Site #8 (Reg ional Occu pational Program Downtown Parcel) is located within an area that has a high
conc entration of hi sto ri c buildings and stru cture s; however, no his toric structures exist on the sl te.21 None
of the Opportunity Sites are located on a pr operty recognized by the National Register of Historic Places
or the State Office of His toric Preservation .22 T herefore, no impact will occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not cause a substantial adverse change in the significance of a historical resource beyond
the previously approved 2014-2021 Housing Element. Site #8 (Regional Occupational Program
Downtown Parcel) is not included in the Amended Opportunity Sites Inventory. None of the new
Opportunity Sites are located on a property recognized by the National Register of Historic Places or the
State Office of Historic Preservation. Therefore, no new impacts will occur.
b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to
15064 .5 of CEQA? Less than Significant with Mitigation Incorporated. Previously Approved 2014-
2021 Housing Element Initial Study Conclusion: According to the City of San Juan Capistrano General
Plan Cultural Resources Element, much of the City is identified as containing prehistoric and historic
archaeological resources.23 Thus, a majority of the Opportunity Sites are located within areas believed to
contain prehistoric and historic archaeological resources. In the unlikely event that archaeological
materials are uncovered, Mitigation Measure C-1 is incorporated to ensure that uncovered resources are
evaluated, left in place if possible, or curated as recommended by a qualified anthropologist or
paleontologist. In addition, General Plan policies require strict adherence to CEQA guidelines where
archaeological or paleontological resources may be affected. Impacts to buried cultural resources will be
less than significant with mitigation incorporated.
General Plan Policies
Cultural Resources Policy 1.1 : Balance the benefits of development with the project's potential impacts
to existing cultural resources.
Cultural Resources Policy 1.2: Identify, designate, and protect buildings and sites of historic
importance.
Cultural Resources Policy 1.3: Identify funding programs to assist private property owners in the
preservation of buildings and sites of historic importance .
2014-2021 Housing Element Initial Study Addendum Conclusion : The Amended 2014-2021 Housing
Element will not cause a substantial adverse change in an archaeological resource beyond the previously
Initial Study/Environmental Checklist -50-City of San Juan Capistrano, California
approved 2014-2021 Housing Element. As mentioned in the previously approved 2014-2021 Housing
Element Initial Study, according to the City of San Juan Capistrano General Plan Cultural Resources
Element, much of the City is identified as containing prehistoric and historic archaeological resources.
Thus, a majority of the new Opportunity Sites are located within areas believed to contain prehistoric and
historic archaeological resources. In the unlikely event that archaeological materials are uncovered, the
Amended 2014-2021 Housing Element will also adhere to Mitigation Measure C-1 Mitigation Measure C-1
to ensure that uncovered resources are evaluated, left in place if possible, or curated as recommended
by a qualified anthropologist or paleontologist. In addition, General Plan policies require strict adherence
to CEQA guidelines where archaeological or paleontological resources may be affected. Impacts to
buried cultural resources will be less than significant with mitigation incorporated . No new impacts will
occur.
c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Less
than Significant with Mitigation Incorporated. Previously Approved 2014-2021 Housing Element Initial
Study Conclusion: Paleontological resources have been uncovered in various portions of the City. The
valley area, with its alluvial deposits has less potential to produce fossils, while the older foothills have a
higher potential to yield fossils. The Capistrano and Monterey Formations and San Onofre Breccia,
mainly located in the eastern foothills of the City , are cons idered to be of high ~aleontological importance
due to the numerous fossil sites which have been found in these bedrock units. 4 Paleonto logical sites are
abundant in southern Orange County, especially along the coast and in creek areas. In the event that
paleontological materials are uncovered, Mitigation Measure C-1 is incorporated to ensure that uncovered
resources are evaluated, left in place if possible, or curated as recommended by a qualified
anthropologist or paleontologist. Impacts to buried cultural resources will be less than significant with
mitigation incorporated.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not cause a substantial adverse change in an paleontological resource beyond the
previously approved 2014-2021 Housing Element. As mentioned in the previously approved 2014-2021 ·
Housing Element Initial Study, paleontological resources have been uncovered in various portions of the
City. Paleontological sites are abundant in southern Orange County, especially along the coast and in
creek areas. The Amended 2014-2021 Housing Element will also adhere to Mitigation Measure C-1 in the
event that paleontological materials are uncovered to ensure that uncovered resources are evaluated, left
in place if possible, or curated as recommended by a qualified anthropologist or paleontologist. Impacts to
buried cultural resources will be less than significant with mitigation incorporated. No new impacts will
occur.
d) Disturb any human remains, including those interred outside of formal cemeteries? Less than
Significant with Mitigation Incorporated. Previously Approved 2014-2021 Housing Element Initial
Study Conclusion: No known cemeteries or human burials have been identified in the proposed housing
development sites. However, it is possible that unknown human remains could be located in the area, and
if proper care is not taken during future housing project construction completed pursuant to Housing
Element policy, particularly during excavation activities, damage to or destruction of these unknown
remains could occur. To ensure that any such materials or human remains, if found, are properly
identified (and the resource recovered, if necessary), before grading or other earthmoving activities
proceed in that immediate area, Mitigation Measure C-1 is included. Mitigation Measure C-1 requires
compliance with state law for the notification and recovery of buried remains. Impacts to buried remains
will be less than significant with mitigation incorporated.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not disturb any human remains beyond the previously approved 2014-2021 Housing
Element. No known cemeteries or human burials have been identified on the new Opportunity sites. As
mentioned in the previously approved 2014-2021 Housing Element Initial Study, it is possible that
unknown human remains could be located in the area, and if proper care is not taken during future
housing project construction completed pursuant to Housing Element policy, particularly during
excavation activities, damage to or destruction of these unknown remains could occur. The Amended
2014-2021 Housing Element will also adhere to Mitigation Measure C-1 to ensure that any such materials
or human remains, if found, are properly identified (and the resource recovered, if necessary), before
Initial Study/Environmental Checklist -51-City of San Juan Capistrano, California
grading or other earthmoving activities proceed in that immediate area. Mitigation Measure C-1 requires
compliance with state law for the notification and recovery of buried remains. Impacts to buried remains
will be less than significant with mitigation incorporated . No new impacts will occur.
Mitigation Measure C-1 :
In the event that subsurface resources are encountered during the course of grading and/or excavation
for projects completed pursuant to Housing Element policy, all development shall temporarily cease in
these areas until the City of San Juan Capistrano Planning Division is contacted and agrees upon a
qualified archaeologisVpaleontologist to be brought onto the project site to properly assess the resources
and make recommendations for their disposition. In the event that human remains are discovered, there
sh all be no disposition of such human remains , oth er than in acco rd ance with the procedures and
requirements set forth in California Health and Sa fety Code Section 70 50 .5 and Public Resources Code
Section 5097 .98 . These code provisions require notification of the County Coroner and the Native
American Heritage Commission, who in turn must notify those persons believed to be most likely
descended from the deceased Native American for appropriate disposition of the remains. The applicable
project applicant shall bear all costs associated with implementing this mitigation measure.

b. Result in substantial soil erosion or the loss of topsoil? 0 0 ~ 0
c. Be located on a geologic unit or soil that is unstable, or that would
become unstable as a result of the project, and potentially result in n D ~ D on-site or off-site landslide, lateral spreading, subsidence,
liquefaction or collapse?
d. Be located on expansive soil, as defined in Table 18-1-B of the 0 D ~ 0 1994 UBC, creating substantial risks to life or property?
e. Have soils incapable of adequately supporting the use of septic
tanks or alternative waste water disposal systems where sewers 0 0 0 r8J
are not available for the disposal of waste water?
a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or
death involving:
i) Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault
Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known
fault? Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study
Conclusion: The project site is located within the seismically active southern California region and would
likely be subjected to grou nd shaking, thus exposing existing facili ties to seismic hazards . No known
acti ve seis mic faults tr averse the City of San Juan Cap istrano.25 Ho we ver, the City is located within 50
miles of several known potential sources of strong shaking, including the offshore segment of the
Newport-Inglewood fault system located approximately six miles west of the City and the San Andreas
Fault system located approximately 50 miles east of the city. The City is not identified as an Alquist-Priolo
Earthquake Fault Zone. Furthermore the County of Orange General Plan indicates that the project site is
not within an Alquist Priolo Special Study Zone . The General Plan and zoning code amendments do not
increase any risks associated with fault rupture, as no land use policy changes are proposed which would
allow development where it was not previously permitted, however the amendments will increase
development intensities by increasing the maximum residential density. No changes are proposed to
General Plan policies in place to protect against earthquake hazards . Future housing development
constructed pursuant to Housing Element policy would be subject to all applicable City, state, and local
building regulations, including t.he California Building Code (CBC) seismic standards as approved by the
City Building & Safety Division. Impacts would be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not expose people or structures to potential substantial adverse effects, including the risk of
loss, injury, or death involving the rupture of a known earthquake fault beyond the previously approved
2014-2021 Housing Element. The new Opportunity sites are located within the seismically active southern
California region and would likely be subjected to groundshaking, thus exposing existing facilities to
seismic hazards. As mentioned in the previously approved 2014-2021 Housing Element Initial Study, no
known active seismic faults traverse the City of San Juan Capistrano. However, the City is located within

development constructed pursuant to Housing Element policy would be subject to all applicable City ,
state, and local building regulations, including the California Building Code (CBC) seismic standards as
approved by the City Building & Safety Division . Impacts would be less than significant. No new impacts
will occur.
ii) Strong seismic ground shaking? Less than Significant Impact. Previously Approved 2014-2021
Housing Element Initial Study Conclusion: Ground shaking can vary greatly due to the variation in earth
properties. The City is subject to strong ground shaking, as is the entirety of Southern California. As
discussed above, the City is not located within an Alquist-Priolo Earthquake Fault Zone, and no trace of
any known active or potentially active fault passes through the identified Opportunity Sites . However, as
with all properties in the seismically active Southern California region, all future projects would be
susceptible to ground shaking during a seismic event and could expose persons and structure to
potentially medium to strong seismic ground motion . As such, all futu re projects could result in a
potentially significant impact with respect to strong ground shaking. There are several active and
potentially active fault zones in the region that could affect the project site. The faults include the
Cristianitos, Laguna Canyon, Shady Canyon, T empl e Hill, offshore Newport-I ng lewood, offsho re Palos
Verdes, Elsinore, San Jacinto, and San An dreas.26 A future, site-sp ecifi c project invol ving physical
development of the property would be required to be in conformance with the Uniform Building Code
(UBC), the C ity's Seismic Hazard Mitig ation Ordin anc e, an d oth er ap plica bl e standard s. This pr oj ect will
have no impact as' no ph ys ical imp roveme nts are pro pose d that would alter ex isting condi t ion s.
Nonetheless, as discussed above in Section Vl (a)(i), all f uture projec ts would be desi gned a nd
constructed in compliance with all applicable City and state cod es and re quirements, inc luding th ose
established in the California Code of Regulations, Title 24, Part 2, Volume 2 . The CBC regulations are
designed to protect building occupants and limit the damage sustained by buildings during seismic
events. The General Plan Safety Element identifies seismicity as a key safety issue and contains the
following goals and policies to reduce seismic hazards within the City. In addition , a soil investigation
report is required as a condition of approval of the General Plan EIR. Therefore, impacts will be less than
significant.
General Plan Policies
Safety Element Policy1.1: Reduce the risk of impacts from geologic and seismic hazards by applying
proper development engineering, building construction, and retrofitting
requirements.

2021 Housing Element will have no impact as no physical improvements are proposed that would alter
existing conditions. Nonetheless, as discussed in the previously approved 2014-2021 Housing Element
Init ial St ud y Section Vl(a)(i), all future pr ojec ts would be designed and co nstructed in compliance with all
ap pl ic ab le City and state codes and re quirements, including those estab li shed in the California Code of
Regulations, Title 24, Part 2, Volume 2. The CBC regulations are designed to protect building occupants
and limit the damage sustained by buildings during seismic events. The General Plan Safety Element
identifies seismicity as a key safety issue and contains the following goals and policies to reduce seismic
hazards within the City. In addition, a soil investigation report is required as a condition of approval of the
General Plan EIR. Therefore, impacts will be less than significant and no new impacts will occur.
iii) Seismic-related ground failure , including liquefaction? Less than Significant Impact. Previously
Initial Study/Environmental Checklist -54-City of San Juan Capistrano, California
Approved 2014-2021 Housing Element Initia l Study Conclusion: Liquefaction is a phenomenon that
occurs when soil undergoes transformation from a solid state to a liquefied condition due to the effects of
increased pore-water pressure. This typically occurs where susceptible soils (particularly the medium
sand to silt range) are located over a high groundwater table. Affected soils lose all strength during
liquefaction and foundation failure can occur.
A large portion of the City is susceptible possible ground failure due to liquefaction hazards.27 The
potential for liquefaction is particular ly hig h in th e f loo dways located downstream of the confl uence of San
Juan Creek and Trabuco Creek.28 Th e City reco gni ze s the potential impacts to hou sing and has included
Policy 1.1 within the General Plan Safety Element (listed above). These policies require the review of
soils and geologic conditions for liquefaction potential. The City's Seismic Hazard Mitigation Ordinance
contains requirements for structural design of new development and redevelopment to minimize structural
damage from earthquakes and their secondary effects, such as liquefaction .
Areas subject to liquefaction are noted in Figure S-1 (Geologic Hazards Map) in the General Plan Safety
Element. The proposed opportunity sites are located in areas identified by the General Plan as having the
potential for liquefaction. However, appropriate measures that reduce the ground-shaking and liquefaction
effects of earthquakes are identified in the California Building Code, including specific provisions for
seismic design of structures . The project does not itself involve new construction in any area of the City .
All future development projects will be subject to the City's standard environmental review process for
evaluation of liquefaction potential and other geologic hazards. Considering implementation of existing
policies and standards, impacts associated with liquefaction or other ground failure will be less than
significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not expose people or structures to seismic-related ground failure, including liquefaction
beyond the previously approved 2014-2021 Housing Element. As mentioned in the previously approved
2014-2021 Housing Element Initial Study, a large portion of the City is susceptible possible ground failure
due to liquefaction hazards. The City recognizes the potential impacts to housing and has included Policy
1.1 within the General Plan Safety Element. This policy requires the review of soils and geologic
conditions for liquefaction potential. The City's Seismic Hazard Mitigation Ordinance contains
requirements for structural design of new development and redevelopment to minimize structural damage
from earthquakes and their secondary effects, such as liquefaction . The proposed new Opportunity Sites
are located in areas identified by the General Plan as having the potential for liquefaction. However,
appropriate measures that reduce the ground-shaking and liquefaction effects of earthquakes are
identified in the California Building Code, including specific provisions for seismic design of structures.
The 2014-2021 Housing Element Addendum does not itself involve new construction in any area of the
City. All future development projects will be subject to the City's standard environmental review process
for evaluation of liquefaction potential and other geologic hazards. Considering implementation of existing
policies and standards, impacts associated with liquefaction or other ground fa ilure will be less than
significant. No new impacts will occur.
iv) Landslides? Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial
Study Conclusion : Landslides are mass movements of the ground that include rock falls, relatively
shallow slumping and sliding of soil, and deeper rotational or transitional movement of soil or rock . In
general, landslides are abundant in areas underlain by shale and siltstone bedrock materials. The
bedrock units most susceptible to landsliding are the Capistrano (Tc) and Monterey (Tm) formations. The
Capistrano Formation comprises much of the Cit y's hillside slopes. Several of the Opport uni ty Sites are
within a known or highly suspected landslide area. 29 30 Successful develop me nt in po rti on s of the City
subject to landslides requires detailed engineering analysis and continuous inspection during
construction. During review of development and redevelopment proposals, the City requires surveys of
geological conditions by state licensed engineering geologists and civil engineers when appropriate.
Impacts will be less than significant with implementation of existing regulations and City review
processes .
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Initial Study/Environmental Checklist -55-City of San Juan Capistrano, California
Element will not expose people or structures to landslides beyond the previously approved 2014-2021
Housing Element. As mentioned in the previously approved 2014-2021 Housing Element Initial Study, the
City requires surveys of geological conditions by state licensed engineering geologists and civil engineers
when appropriate during review of development and redevelopment proposals . Impacts will be less than
significant with implementation of existing regulations and City review processes. No new impacts will
occur.
b) Result in substantial soil erosion or the loss of topsoil? Less than Significant Impact. Previously
Approved 2014-2021 Housing Element Initial Study Conclusion: Topsoil is used to cover surface areas for
the establishment and maintenance of vegetation due to its high concentrations of organic matter and
microorganisms. Little, if any, native topsoil is likely to occur at any of the Opportunity Sites since the area
has historically been developed. Furthermore, the project does not propose or authorize any particular
housing development, infrastructure project, or other development activity. The project does propose
General Plan and Municipal Code amendments to increase the maximum residential density and to
update the Density Bonus Program. All future development projects are subject to environmental and
engineering review, including assessment and mitigation of soil erosion. During construction activities of
housing proposed pursuant to Housing Element policy, there is the potential to expose surficial soils to
wind and water erosion during construction activities . Wind erosion is required to be minimized through
soil stabilization measures required by South Coast Air Quality Management District (SCAQMD) Rule 403
(Fugitive Dust), such as daily watering. Water erosion will be prevented through the City's standard
erosion control practices required pursuant to the California Building Code and the National Pollution
Discharge Elimination System (NPDES), such as silt fencing or sandbags. Impacts related to soil erosion
would be less than significant with implementation of existing regulations .
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in substantial soil erosion or the loss of topsoil beyond the previously approved
2014-2021 Housing Element. As mentioned in the previously approved 2014-2021 Housing Element
Initial Study, all future development projects are subject to environmental and engineering review,
including assessment and mitigation of soil erosion. During construction activities of housing proposed
pursuant to Housing Element policy, there is the potential to expose surficial soils to wind and water
erosion during construction activities. Wind erosion is required to be minimized through soil stabilization
measures required by South Coast Air Quality Management District (SCAQMD) Rule 403 (Fugitive Dust),
such as daily watering. Water erosion will be prevented through the City's standard erosion . control
practices required pursuant to the California Building Code and the National Pollution Discharge
Elimination System (NPDES), such as silt fencing or sandbags . Impacts related to soil erosion would be
less than significant with implementation of existing regulations. No new impacts will occur.
c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the
project, and potentially result in on-or off-site landslide, lateral spreading, subsidence, liquefaction or
collapse? Less than Significant Impact. Previously Approved 2014 -2021 Housing Element Initial Study
Conclusion: Liquefaction and seismically induced settlement or ground failure are generally associated
with strong seismic shaking in areas where ground water tables are at relatively shallow depths (within 50
feet of the ground surface) and/or when the area is underlain by loose , cohesionless deposits. During a
strong ground shaking event, saturated, cohesionless soils may acquire a degree of mobility to the extent
that the overlying ground surface distorts. In extreme cases, saturated soils become suspended in
groundwater and become fluid-like. Seismic settlement often occurs when loose to medium dense
granular soils settle during ground shaking, and can cause structural damage to buildings when
settlement is non-uniform. Such ground settlement hazards may be identified by on-site geologic
investigations that are required of individual developments. No subsidence has been reported within San
Juan Capistrano.
General Plan Safety Element Policy 1.1 listed above and the CBC requires all new development to have
a site-specific geology report prepared by a registered geologist or soils expert and submitted to the City,
which would ensure impacts related to expansive soils would be evaluated on a project-by-project basis
and mitigated as necessary. Compliance with the goals and policies of the General Plan and the Building
Code would ensure potential impacts would be reduced to a less than significant level.
Initial Study/Environmental Checklist -56-City of San Juan Capistrano, California
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in impacts related to unstable soils beyond the previously approved 2014-2021
Housing Element. As mentioned in the previously approved 2014-2021 Housing Element Initial Study, the
General Plan Safety Element Policy 1.1 listed above and the CBC requires all new development to have
a site-specific geology report prepared by a registered geologist or soils expert and submitted to the City,
which would ensure impacts related to expansive soils would be evaluated on a project-by-project basis
and mitigated as necessary. Compliance with the goals and policies of the General Plan and the Building
Code would ensure potential impacts would be reduced to a less than significant level. No new impacts
will occur.
d) Be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1997), creating
substantial risks to life or property? Less than Significant Impact. Previously Approved 2014-2021
Housing Element Initial Study Conclusion: Expansion and contraction of volume can occur when
expansive soils undergo alternating cycles of wetting (swelling) and drying (shrinking). During these
cycles, the volume of the soil changes markedly, and can cause structural damage to building and
infrastructure if the potentially expansive soils were not considered in project design and construction.
Compaction of loose soils and poorly consolidated alluvium occur as a result of strong seismic shaking.
The amount of compaction may vary from a few inches to several feet and may be significant in areas of
thick soil cover. Topsoil, recent alluvium and weathered bedrock are typically porous and may be subject
to hydro-collapse; therefore, these materials can be considered unsuitable for the support of engineered
fills and structures. The soils of the Monterey and Capistrano formations are considered moderately to
highly expansive, thus expansive soils are considered a hazard in San Juan Capistrano.31 32 The CBC
requires that a soil and geological report be prepared for any development, including future potential
housing. Presence of expansive soils and identification of measures to eliminate this constraint (such as
removal and replacement with suitable engineered materials) will be determined through site-specific
geotechnical evaluations to be conducted as part of the City's routine development review procedures.
Such routine procedures will apply to all future development projects. As such, potential impacts
associated with expansive soils would be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in impacts related to expansive soils beyond the previously approved 2014-2021
Housing Element. As mentioned in the previously approved 2014-2021 Housing Element Initial Study, the
soils of the Monterey and Capistrano formations are considered moderately to highly expansive, thus
expansive soils are considered a hazard in San Juan Capistrano. The CBC requires that a soil and
geological report be prepared for any development, including future potential housing. Presence of
expansive soils and identification of measures to eliminate this constraint (such as removal and

evaluations to be conducted as part of the City's routine development review procedures. Such routine
procedures will apply to all future development projects. As such, potential impacts associated with
expansive soils would be less than significant. No new impacts will occur.
e) Have soils incapable of adequately supporting the use of septic tanks or alternative wastewater
disposal systems where sewers are not available for the disposal of wastewater? No Impact. Previously
Approved 2014-2021 Housing Element Initial Study Conclusion: San Juan Capistrano is served by a fully
functional sewer system. No septic systems will be utilized in future development. No impacts could
occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in impacts related to the use of septic tanks or alternative wastewater disposal
systems beyond the previously approved 2014-2021 Housing Element. As mentioned in the previously
approved 2014-2021 Housing Element Initial Study, San Juan Capistrano is served by a fully functional
sewer system. No septic systems will be utilized in future development. No new impacts will occur.

16.7 GREENHOUSE GAS EMISSIONS. Would the project:

purpose of reducing the emissions of greenhouse gases?

a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on
the environment? Less than Significant Impact. Previously Approved 2014-2021 Housing Element
Initial Study Conclusion: Climate change is the distinct change in measures of climate for a long period of
time. Climate change is the result of numerous, cumulative sources of greenhouse gas emissions all over
the world. Natural changes in climate can be caused by indirect processes such as changes in the Earth's
orbit around the Sun or direct changes within the climate system itself (i.e. changes in ocean circulation).
Human activities can affect the atmosphere through emissions of greenhouse gases (GHG) and changes
to the planet's surface. Human activities that produce GHGs are the burning of fossil fuels (coal, oil and
natural gas for heating and electricity, gasoline and diesel for transportation); methane from landfill
wastes and raising livestock, deforestation activities; and some agricultural practices.
Greenhouse gases differ from other emissions in that they contribute to the "greenhouse effect." The
greenhouse effect is a natural occurrence that helps regulate the temperature of the planet. The majority
of radiation from the Sun hits the Earth's surface and warms it. The surface in turn radiates heat back
towards the atmosphere, known as infrared radiation. Gases and clouds in the atmosphere trap and
prevent some of this heat from escaping back into space and re-radiate it in all directions. This process is
essential to supporting life on Earth because it warms the planet by approximately 60° Fahrenheit.
Emissions from human activities since the beginning of the industrial revolution (approximately 250 years
ago) are adding to the natural greenhouse effect by increasing the gases in the atmosphere that trap
heat, thereby contributing to an average increase in the Earth's temperature. Greenhouse gases occur
naturally and from human activities. Greenhouse gases produced by human activities include carbon
dioxide (C02), methane (CH4), nitrous oxide (N20), hydrofluorocarbons (HFCs), perfluorocarbons
(PFCs), and sulfur hexafluoride (SF6). Since 1750, it is estimated that the concentrations of carbon
dioxide, methane, and nitrous oxide in the atmosphere have increased over 36 percent, 148 percent, and
18 percent, respectively, primarily due to human activity. Emissions of greenhouse gases affect the
atmosphere directly by changing its chemical composition while changes to the land surface indirectly
affect the atmosphere by changing the way the Earth absorbs gases from the atmosphere.
No new development is associated with the General Plan Amendments proposed to address AB 162. As
such, these amendments would not generate greenhouse gas emissions either directly or indirectly.
GHG emissions for the build-out of housing units facilitated by the Housing Element were quantified
utilizing the California Emissions Estimator Model (CaiEEMod) version 2011.1.1 to determine if the project
could have a cumulatively considerable impact related to greenhouse gas emissions. A numerical
threshold for determining the significance of greenhouse gas emissions in the South Coast Air Basin has
not officially been adopted by the SCAQMD. Individual projects may be required to have a greenhouse
gas emissions inventory, prepared to determine if individual projects exceed applicable screening or
impact thresholds and would thus potentially contribute substantially to climate change and associated
impacts. A summary of short-and long-term emissions and the analysis for each are included below.
Short-Term Emissions
Future development projects will result in short-term greenhouse gas emissions from construction.
Greenhouse gas emissions will be released by equipment used for demolition, grading, paving, and other
building construction activities. GHG emissions will also result from worker and vendor trips to and from
Initial Study/Environmental Checklist -59-City of San Juan Capistrano. California
project sites and from demolition and soil hauling trips . Construction activities are short-term and cease to
emit greenhouse gases upon completion, unlike operational emissions that are continuous year after year
until operation of the use ceases. Because of this difference, SCAQMD recommends that construction
emissions be amortized over a 30-year operational lifetime. This normalizes construction emissions so
that they can be grouped with operational emissions in order to generate a precise project GHG
inventory.
Typically, construction-related GHG emissions contribute insubstantially (less than one percent) to a
project's annual greenhouse gas emissions inventory and mitigation is not effective in reducing a project's
overall contribution to climate change . Implementation of AB32 and SB375 through California Air
Resources Board's (ARB) Scoping Plan and SCAG's RTP/SCS are designed to achieve the required
reduction in greenhouse gas emissions, as is further discussed in Section 16.7.b. With the cooperation
and support of these plans, short-term climate change impacts due to future construction activities will be
less than significant.
Long-Term Emissions
Future development projects will result in continuous GHG emissions from mobile, area, and other
operational sources. Mobile sources, including vehicle trips to and from development projects, will result
primarily in emissions of C02, with minor emissions of CH4 and N20. The most significant GHG emission
from natural gas usage will be methane. Electricity usage by future development and indirect usage of
electricity for water and wastewater conveyance will result primarily in emissions of carbon dioxide.
Disposal of solid waste will result in emissions of methane from the decomposition of waste at landfills
coupled with C02 emission from the handling and transport of solid waste . These sources combine to
define the long-term greenhouse gas inventory for typical development projects .
Table 8 (Opportunity Sites Proposed Greenhouse Gas Emissions Inventory for the Previously Approved
Opportunity Sites) summarizes annual operational impacts from maximum allowed development on the
identified Opportunity Sites. This represents a worst-case scenario and does not account for uses
currently in operation at the Opportunity Sites. There is no adopted threshold promulgated by SCAQMD
or CARB for assessment of program-level GHG emissions. Analysis of program-level climate change
impacts are assessed through consistency with state and regional greenhouse gas emissions reduction
plans and identification of policies, regulations, and rules that will reduce pollutant emissions from future
development projects. Consistency analysis with state and regional greenhouse gas emissions reductions
plans is provided in Section 16.7.b.

b) Conflict with an applicable plan, policy or regulation adopted for the purpose of reducing the emissions
of greenhouse gases? No Impact. Previously Approved 2014-2021 Housing Element Initial Study
Conclusion: Significant impacts would occur if the proposed project conflicted with or interfered with
implementation of any existing GHG reduction plan that is projected to achieve greenhouse gas reduction
targets. The two primary reduction plans are California Air Resources Board (CARS) Seeping Plan and
SCAG's Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS), as discussed
below.
California Air Resources Board Scoping Plan (AB32)
The CARB Seeping Plan is the comprehensive plan to reach the GHG reduction targets stipulated in
AB32. The key elements of the plan are to expand and strengthen energy efficiency programs, achieve a
statewide renewable energy mix of 33 percent, develop a cap-and-trade program with other partners in
the Western Climate Initiative (includes seven states in the United States and four territories in Canada),
establish transportation-related targets, and establish fees. CARB estimates that implementation of these
measures will reduce GHG emissions in the state by 136 MMTC02E by 2020; therefore, implementation
of the Scoping Plan will meet the 2020 reduction target of 80 MMTC02E, which is a reduction of 27
percent compared to the projected business as usual 507 MMTC02E.
Many of the strategies identified in the Scoping Plan are not applicable at the General Plan or project
level, such as long-term technological improvements to reduce emissions from vehicles. Some measures
are applicable and supported by the project, such as provision of mixed-use developments . Finally, while
some measures are not directly applicable, the project would not conflict with their implementation.
Reduction measures are grouped into 18 action categories, as follows:
1. California Cap-and-Trade Program Linked to Western Climate Initiative Partner Jurisdictions.
Implement a broad-based California cap-and-trade program to provide a firm limit on emissions. Link the
California cap-and-trade program with other Western Climate Initiative Partner programs to create a
regional market system to achieve greater environmental and economic benefits for California. Ensure
California's program meets all applicable AB 32 requirements for market-based mechanisms. These
programs involve capping emissions from electricity generation, industrial facilities, and broad scoped
fuels. The project does not involve any such uses.
2. California Light-Duty Vehicle Greenhouse Gas Standards. Implement adopted Pavley standards
and planned second phase of the program. Align zero-emission vehicle, alternative and renewable fuel
and vehicle technology programs with long-term climate change goals. This is not applicable as this is a
statewide measure establishing vehicle emissions standards.
3. Energy Efficiency. Maximize energy efficiency building and appliance standards, and pursue
additional efficiency efforts including new technologies, and new policy and implementation mechanisms.
Pursue comparable investment in energy efficiency from all retail providers of electricity in California
(including both investor-owned and publicly owned utilities). The City's General Plan and proposed
Housing Element promotes energy efficient building design , as well as implementation of existing building
and other codes regulating minimum energy, water, and waste efficiency consistent with 2011
CALGREEN requirements and would thus be consistent and not interfere with this program.
4. Renewables Portfolio Standards. Achieve 33 percent renewable energy mix statewide by 2020.
This establishes the minimum statewide renewable energy mix and is not applicable at a City level or
below for implementation. The proposed General Plan Amendments would not interfere with the
implementation of this program.
5. Low Carbon Fuel Standard. Develop and adopt the Low Carbon Fuel Standard. This is not
applicable to a City as this establishes reduced carbon intensity of transportation fuels.
Initial Study/Environmental Checklist -62-City of San Juan Capistrano, California
6. Regional Transportation-Related Greenhouse Gas Targets. Develop regional greenhouse gas
emissions reduction targets for passenger vehicles . As is detailed below, the proposed General Plan
Amendments would not potentially conflict with and would support the implementation of SCAG's
RTP/SCS to achieve the required GHG reduction goals by 2020 and 2035 based on consistency with
growth projections. The existing General Plan includes policies to reduce vehicle miles traveled by
encouraging mixed-use, infill, and improved jobs-housing balance, and alternative modes of
transportation.
7. Vehicle Efficiency Measures. Implement light-duty vehicle efficiency measures. This is not
applicable to a city as this identifies measures such as minimum tire-fuel efficiency, lower friction oil, and
reduction in air conditioning use.
8. Goods Movement. Implement adopted regulations for the use of shore power for ships at berth.
Improve efficiency in goods movement activities. Identifies measures to improve goods movement
efficiencies such as advanced combustion strategies, friction reduction, waste heat recovery, and
electrification of accessories. The proposed General Plan Amendments will not result in the development
of uses that will involve the movement of goods and therefore would not interfere with eventual
implementation.
9. Million Solar Roofs Program. Install 3,000 megawatts of solar-electric capacity under California's
existing solar programs. Sets goal for use of solar systems throughout the state. The proposed General
Plan Amendments would not interfere with but instead would directly support installation of alternative
energy sources through existing General Plan policies and programs.
10. Medium-and Heavy-Duty Vehicles. Adopt medium-duty (MD) and heavy-duty (HD) vehicle
efficiencies. Aerodynamic efficiency measures for HD trucks pulling trailers 53-feet or longer that include
improvements in trailer aerodynamics and use of rolling resistance tires were adopted in 2008 and went
into effect in 2010. Future, yet to be determined improvements, includes hybridization of MD and HD
trucks. The proposed Housing Element would not directly result in development of industrial uses. In
addition, this type of development would be required to have their fleet equipment be consistent with the
current applicable efficiency measures at the time of operation. The proposed General Plan Amendments
would not interfere with implementation of this program .
11. Industrial Emissions. Require assessment of large industrial sources to determine whether
individual sources within a facility can cost-effectively reduce greenhouse gas emissions and provide
other pollution reduction co-benefits. Reduce greenhouse gas emissions from fugitive emissions from oil
and gas extraction and gas transmission. Adopt and implement regulations to control fugitive methane
emissions and reduce flaring at refineries. These measures are applicable to large industrial facilities {>
500,000 MTC02E/YR) and other intensive uses such as refineries. While it is unlikely that a qualifying
heavy industrial facility such as these would be located in the City, if one were, it would be subject to
these state requirements; the proposed General Plan Amendments would not interfere with
implementation.
12. High Speed Rail. Support implementation of a high speed rail system. This is not applicable as the
General Plan Amendments have no bearing on high speed rail facilities.
13. Green Building Strategy. Expand the use of green building practices to reduce the carbon footprint
of California's new and existing inventory of buildings. The existing General Plan and proposed Housing
Element promotes energy efficient building design as well as implementation of existing building and
other codes regulating minimum energy, water, and waste efficiency consistent with 2011 CALGREEN
requirements and would thus be consistent and not interfere with this program. General Plan
Amendments to comply with AB 162 do not pertain to new building projects or building strategies and
would not interfere with any green building programs.
14 . High Global Warming Potential Gases. Adopt measures to reduce high global warming potential
gases. The proposed General Plan Amendments would not directly result in generation of high global
Initial Study/Environmental Checklist -63-City of San Juan Capistrano, California
warming potential gases, and would not interfere with implementation of any future changes in air
conditioning, fire protection suppressant, or other emission requirements.
15. Recycling and Waste. Reduce methane emissions at landfills. Increase waste diversion, composting
and other beneficial uses of organic materials, and mandate commercial recycling to move toward zero-
waste. The proposed Housing Element is consistent since implementing housing development will be
required to recycle a minimum of 50 percent from construction activities per state requirements . General
Plan Amendments to comply with AB 162 do not permit any specific new development to occur and thus
would not interfere with any recycling and waste-reduction programs.
16. Sustainable Forests. Preserve forest sequestration and encourage the use of forest biomass for
sustainable energy generation. The 2020 target for carbon sequestration is 5 million MTC02E/YR. This is
not applicable as the City does not contain any areas defined as forest.
17. Water. Continue efficiency programs and use cleaner energy sources to move and treat water. The
proposed Housing Element is consistent since implementing development will include use of low-flow
fixtures and water efficient landscaping per state requirements. General Plan Amendments to comply with
AB 162 do not pertain to new building projects or building strategies and thus would not interfere with any
water conservation programs.
18. Agriculture. In the near-term, encourage investment in manure digesters and at the five-year
Scoping Plan update determine if the program should be made mandatory by 2020. The City does not
contain any agricultural land use designations, and any policies related to agriculture land uses would not
be applicable.
As summarized above, the proposed General Plan Amendments will not potentially conflict with Regional
Transportation-Related GHG targets and would not conflict with any of the other provisions of the Scoping
Plan. The existing General Plan and proposed General Plan Amendments in fact support four of the
action categories through energy efficiency, green building, recycling/waste, and water conservation
through these proposed and current policies.
Regional Transportation Plan/Sustainable Communities Strategy (58375)
The 2012 Regional Transportation Plan/Sustainable Communities Strategy and the goals, -policies, and
programs included within it are projected to obtain and exceed applicable GHG reduction targets of eight
percent by 2020 and 13 percent by 2035 . Projected reductions by the RTP/SCS are nine percent by 2020
and 16 percent by 2035. Ultimately, the RTP/SCS is keyed to implement the requirements of AB32 at the
regional level. For a program-level analysis, if the proposed General Plan Amendments are consistent
with the assumptions of the RTP/SCS, then long-term development within the planning area will meet
regional reduction targets. Furthermore, long-term development would meet the broader statewide
reduction goals of 1990 levels by 2020 and 80 percent beyond that by 2050. The proposed General Plan
Amendments would, therefore, not contribute substantially to climate change impacts if they are
consistent with the regional and statewide climate change planning efforts.
As assumed in the RTP/SCS, based on current City boundaries, San Juan Capistrano is forecast to grow
to a total population of 38,100 by 2020 and 37,800 by 2035. Build-out of the General Plan would result in
a population of 38,520 persons, slightly higher than that estimated by SCAG. The projected growth is
generally consistent. In addition, the proposed Housing Element and opportunity sites are projected to
meet the City's allocated RHNA. Therefore, by providing sites to accommodate the RHNA, the Housing
Element is contributing short-term towards consistency with long-term growth projections and the
RTP/SCS. Therefore, the existing General Plan and proposed Housing Element is consistent with the
population growth forecasts of the RTP/SCS because it does provide the capacity for residential
development to accommodate the projected population growth and not direct growth elsewhere, which
would interfere with implementation of the RTP/SCS.
The Housing Element includes a section discussing potential ene rg y conservation opportunities, including
the encouragement of "green buildings" that are designed/renovate/re-used /op erated in a manner that
enhances resource efficiency. The Housing Element also encourages the use of energy conservation
Initial Study/Environmental Checklist -64-City of San Juan Capistrano, California
devices and maximum utilization of federal, state and local government programs including the Orange
County Home Weatherization Program. These programs are intended to help homeowners implement
energy conservation measures. Additionally, Southern California Edison offers various rebate programs
for energy efficient appliances and makes available to residents energy efficient kits at no cost. Housing
implementation programs include efforts to promote energy efficiency improvements to households, as
well as energy efficient housing design and practices in City ordinances. No impact will occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not conflict with an applicable plan, policy or regulation adopted for the purpose of reducing
the emissions of greenhouse gases beyond the previously approved 2014-2021 Housing Element.
Significant impacts would occur if the 2014-2021 Housing Element Addendum conflicted with or interfered
with implementation of any existing GHG reduction plan that is projected to achieve greenhouse gas
reduction targets. The two primary reduction plans are California Air Resources Board (GARB) Seeping
Plan and SCAG's Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS).
California Air Resources Board Seeping Plan (AB32)
As mentioned in the previously approved 2014-2021 Housing Element Initial Study, many of the
strategies identified in the Seeping Plan are not applicable at the General Plan or project level, such as
long-term technological improvements to reduce emissions from vehicles. Some measures are applicable
and supported by the project, such as provision of mixed-use developments. Finally, while some
measures are not directly applicable, the project would not conflict with their implementation . Reduction
measures are grouped into 18 action categories, which are listed in the previously approved 2014-2021
Housing Element Initial Study.
The proposed General Plan Amendment will not potentially conflict with Regional Transportation-Related
GHG targets and would not conflict with any of the other provisions of the Seeping Plan. The existing
General Plan and proposed General Plan Amendment would in fact support four of the action categories
through energy efficiency, green building, recycling/waste, and water conservation through these
proposed and current policies.
Regional Transportation Plan/Sustainable Communities Strategy (SB375)
As mentioned in the previously approved 2014-2021 Housing Element Initial Study, the 2012 Regional
Transportation Plan/Sustainable Communities Strategy and the goals, policies, and programs included
within it are projected to obtain and exceed applicable GHG reduction targets of eight percent by 2020
and 13 percent by 2035. Projected reductions by the RTP/SCS are nine percent by 2020 and 16 percent
by 2035. Ultimately, the RTP/SCS is keyed to implement the requirements of AB32 at the regional level.
For a program-level analysis, if the proposed General Plan Amendments are consistent with the
assumptions of the RTP/SCS, then long-term development within the planning area will meet regional
reduction targets. Furthermore, long-term development would meet the broader statewide reduction goals
of 1990 levels by 2020 and 80 percent beyond that by 2050. The proposed General Plan Amendments
would, therefore, not contribute substantially to climate change impacts if they are consistent with the
regional and statewide climate change planning efforts .
As assumed in the RTP/SCS, based on current City boundaries, San Juan Capistrano is forecast to grow
to a total population of 38,100 by 2020 and 37,800 by 2035. Build-out of the General Plan would result in
a population of 38,520 persons, slightly higher than that estimated by SCAG. The projected growth is
generally consistent. In addition, the proposed Housing Element and opportunity sites are projected to

RTP/SCS. Therefore, the existing General Plan and proposed Housing Element is consistent with the
population growth forecasts of the RTP/SCS because it does provide the capacity for residential
development to accommodate the projected population growth and not direct growth elsewhere , which
would interfere with implementation of the RTP/SCS .
The Housing Element includes a section discussing potential energy conservation opportunities, including
the encouragement of "green buildings" that are designed/renovate/re-used/operated in a manner that

energy conservation measures. Additionally, Southern Cal ifornia Edison offers various rebate programs
for energy efficient appliances and makes available to residents energy efficient kits at no cost. Housing
implementation programs include efforts to promote energy efficiency improvements to households , as

a) Create a significant hazard to the public or the environment through the routine transport, use, or
disposal of hazardous materials? No Impact. Previously Approved 2014-2021 Housing Element Initial
Study Conclusion: The San Juan Capistrano 2014-2021 Housing Element is a policy document intended
to facilitate maintenance of the existing housing stock and production of new housing to meet the targeted
housing needs of the community. Residentia l development does not require and is not expected to
require the manufacturing, use , transportation, disposal , or storage of dangerous quantities of hazardous
materials. Residential uses do not generate hazardous wastes or emissions , except for very small
quantities of typical household cleaning agents, automotive maintenance products, paints, pesticides, and
herbicides . The proposed Housing Element, General Plan Amendments , and Zoning Code Amendments
would not conflict with any hazardous materials regulations and would not exempt any future
development from the City's programs to control and safely dispose of hazardous materials and wastes or
to reduce the volume of wastes requiring landfill disposal. Thus, no impact will result.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not create a significant hazard to the public or the environment through the routine transport,
use , or disposal of hazardous materials beyond the previously approved 2014-2021 Housing Element.
Residential uses do not generate hazardous wastes or emissions, except for very small quantities of
typical household cleaning agents , automotive maintenance products , paints, pesticides, and herbicides.
The 2014-2021 Housing Element Addendum and General Plan Amendment will not conflict with any
hazardous materials regulations and would not exempt any future development from the City 's programs
lo control and safely dispose of hazardous materials and wastes or to reduce the volume of wastes
Initial Study/Environmental Checklist -67-Cit y of San Juan Capistrano , California
requiring landfill disposal. Impacts regarding the transport, use, or disposal of hazardous materials will be
consistent with the previously approved 2014-2021 Housing Element In itial Study and no new impacts will
occur.
b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and
accident conditions involving the release of hazardous materials into the environment? Less than
Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion : Upon
completion of construction, future residential development that may be facilitated by this Housing Element
update would not generate hazardous air emissions, and would not involve the handling of any acutely
hazardous substances or wastes . Thus, the updated Housing Element would not result in impacts related
to the presence of any hazardous materials or emissions within a quarter mile of a school. The proposed
General Plan and Zoning Code Amendments do not revise any General Plan policies and are limited to
updating the Housing Element and Density Bonus Program, renaming a zoning district and land use
designation while increasing the maximum density, and rezoning three site . These updates and
amendments do not propose or anticipate any specific development proposals or infrastructure
construction. Therefore, these amendments will not result in any impacts that were not addressed in the
General Plan EIR.
With regard to construction, due to the majority of the City being developed , housing development
pursuant to Housing Element policy will likely involve demolition of existing structures . SCAQMD Rule
1403 (Asbestos Emissions from Demolition/Renovation Activities) requires work practices that limit
asbestos emissions from building demolition and renovation activities, including the removal and
disturbance of asbestos containing materials (ACM). This rule is generally designed to protect uses and
persons adjacent to demolition or renovation activity from exposure to asbestos emissions. Rule 1403
requires surveys of any facility being demolished or renovated for the presence of all friable and Class I
and Class II non-friable ACM. Rule 1403 also establishes notification procedures, removal procedures,
handling operations, and warning label requirements, including HEPA filtration, the glovebag method,
wetting, and some methods of dry removal that must be implemented when disturbing appreciable
amounts of ACM (more than 100 square feet of surface area). All future housing developments will be
subject to the City 's standard environmental review process for evaluation of hazards. Considering
implementation of existing policies and standards, impacts associated with asbestos hazards will be less
than significant.
Exposure of construction workers to lead-based paint during demolition activities is also of concern,
similar to exposure to asbestos . Exposure of surrounding land uses to lead from demolition activities is
generally not a concern because demolition activities do not result in appreciable emissions of lead . If
lead contamination exists on future housing sites, 8 CCR Section 1532 .1 (California Construction Safety
Orders for Lead) is applicable to the demolition of all existing structures requiring exposure assessment
and compliance measures to keep worker exposure below action levels. The project is also subject to
Title 22 requirements for the disposal of solid waste contaminated with excessive levels of lead. Impacts
due to lead exposure and contamination will be less than significant with adherence to existing
regulations.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not create a significant hazard to the public or the environment through reasonably
foreseeable upset and accident conditions involving the release of hazardous materials into the
environment beyond the previously approved 2014-2021 Housing Element. As mentioned in the
previously approved 2014-2021 Housing Element Initial Study, all future housing projects will be subject
to th.e City's standard environmental review process as well as existing regulations regarding asbestos
and lead . Impacts regarding the reasonably foreseeable upset and accident conditions involving the
release of hazardous materials will be consistent with the previously approved 2014 -2021 Housing
Element Initial Study and no new impacts will occur.
c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste
within one-quarter mile of an existing or proposed school? Less than Significant Impact. Previously
Approved 2014-2021 Housing Element Initial Study Conclusion: No specific new development is
associated with the Housing Element Update , Density Bonus Program Update and the associated
Initial Study/Environmental Checklist -68-City of San Juan Capistrano, California
General Plan and Zoning Code Amendments. There are three schools located within ~-mile of the
Opportunity Sites: San Juan Elementary School (31642 El Camino Real), San Juan Hills High School
(29211 Vista Montana) and J. Serra High School (31422 Camino Capistrano). Residential development
does not require and is not expected to require the manufacturing, use, transportation, disposal, or
storage of dangerous quantities of hazardous materials. As discussed in Section 16.8 b), existing
regulations address potential off-site construction-related hazards associated with demolition of the
existing onsite structures. Impacts will be less than significant with implementation of existing regulations
listed in Section 16.8 b).
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not emit hazardous emissions or handle hazardous or acutely hazardous materials,
substances, or waste within one-quarter mile of an existing or proposed school beyond the previously
approved 2014-2021 Housing Element. As mentioned in the previously approved 2014-2021 Housing
Element Initial Study, residential development does not require and is not expected to require the
manufacturing, use, transportation, disposal, or storage of dangerous quantities of hazardous materials.
In addition, existing regulations address potential off-site construction-related hazards associated with
demolition of the existing onsite structures. Impacts regarding emitting hazardous emissions or handling
hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or
proposed school will be consistent with the previously approved 2014-2021 Housing Element Initial Study
and no new impacts will occur.
d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to
Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or
the environment? Less than Significant Impact. Previously Approved 2014-2021 Housing Element
Initial Study Conclusion: According to the databases maintained as the Cortese List, the Opportunity Sites
identified in the Housing Element update are not:
• listed as a hazardous waste and substance site by the Department of Toxic Substances Control
(DTSC),33
• listed as a hazardous solid waste disposal site by the SWRCB and CaiEPA,34
• currently subject to a Cease and Desist Order (COO) or a Cleanup and Abatement Order (CAO)
as issued by the SWRCB,35 or
• developed with a hazardous waste facility subject to corrective action by the DTSC.36
There are three open leaking underground storage tank cleanup sites listed by the State Water
Resources Control Board (SWRCB) in the vicinity of the Opportunity Sites. However, no open LUST sites
exist on any of the Opportunity Sites. Since these are open cases, they are already in the process of
remedlating the existing hazards identified and would diminish any potential impacts to future residential
developmen t in the area.37

Initial Study/Environmental Checklist -73-City of San Juan Capistrano , California
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not violate any water quality standards or waste discharge requirements beyond the
previously approved 2014-2021 Housing Element.
The 2014-2021 Housing Element Addendum does not include any components that would change or
conflict with water quality regulations or any waste discharge standards. As mentioned in the previously
approved 2014-2021 Housing Element Initial Study, all new development projects must comply with the
City's local procedures to control storm water runoff to prevent violations of regional water quality
standards, in accordance with its co-permittee obligations under the countywide municipal storm water
permit program, a component of the NPDES program of the Federal Clean Water Act. New housing
projects will be required to comply with Title 8, Chapter 14 (Water Quality Regulations) of the City's
Municipal Code, which contains regulations to meet federal, state, and County water quality requirements
related to urban runoff. Furthermore, General Plan Conservation & Open Space Element Goal 7 which
encourages the protection of water quality and Policy 7.3 which encourages the conservation and
protection of watershed areas . All future development must connect to sewer; direct discharges of
wastewater to surface or ground waters will not be permitted. Impacts regarding water quality standards
or waste discharge requirements will be consistent with the previously approved 2014-2021 Housing
Element Initial Study and no new impacts will occur.
b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such
that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g.,
the production rate of pre-existing nearby wells would drop to a level which would not support existing
land uses or planned uses for which permits have been granted)? Less than Significant Impact.
Previously Approved 2014-2021 Housing Element Initial Study Conclusion: The City receives its water
from three sources. Water is purchased from Metropolitan Water District of Southern California
(MWDSC). MWDSC's imported water sources are a blend of State Water Project water from Northern
California, and water from the Colorado River Aqueduct. Furthermore, the City is supplied with treated
water from the Ground Water Recovery Plant and two potable production wells located in the Northern
portion of the City. The San Juan Valley groundwater basin underlies the City of San Juan Capistrano.
The basin is comprised of four subbasins: Upper San Juan, Middle San Juan, Lower San Juan, and
Lower Trabuco. The City lies within the boundaries of the Lower Trabuco, Lower San Juan, and Middle
San Juan subbasins. Groundwater levels within the lower San Juan Creek are relatively close to ground
surface. Depth to water levels measured during 2004 and 2005 were typically less than twenty feet in the
Lower and Middle San Juan subbasins. Water levels in the Lower Trabuco subbasin were deeper with an
average depth to water of about fifty feet.46 The primary water-bearing unit within the San Juan Valley
Groundwater Basin is Quaternary alluvium. Recharge of the basin is from flow in San Juan Creek, Oso
Creek, and Arroyo Trabuco and precipitation to the valley floor. Wells in this Basin typically yield from 450
to 1,000 gallons per minute.47
Conservation of water resources became increasingly important throughout Southern California in the
1980s and early 1990s, when the entire region suffered a severe drought. In recognition of California's
limited water supply, the City has adopted a Water Conservation Ordinance (Title 6 Sanitation and
Health, Chapter 12 Water Conservation). The purpose of the ordinance is to establish standards and
procedures for year-round water conservation, to promote the efficient use of water, to reduce or
eliminate the waste of water in the City, to complement the City's water quality regulations and urban
runoff reduction efforts, and enable implementation of the City's water shortage contingency measures.
These water conservation programs already in place would result in further protection of groundwater
resources in the City. In addition, the General Plan Conservation & Open Space Element includes
policies to conserve water resources including the production and use of recycled water. Impacts related
to groundwater recharge and depletion will be less .than significant.
General Plan Policies
Conservation & Open Space Policy 7.1: Coordinate water quality and supply programs with the
· responsible water agencies.
Initial Study/Environmental Checklist -74-City of San Juan Capistrano, California
Conservation & Open Space Policy 7.2: Encourage the production and use of recycled water.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not substantially deplete groundwater supplies or interfere substantially with groundwater
recharge beyond the previously approved 2014-2021 Housing Element. As mentioned in the previously
approved 2014-2021 Housing Element Initial Study, the City has adopted a Water Conservation
Ordinance (Title 6 Sanitation and Health, Chapter 12 Water Conservation). The purpose of the ordinance
is to establish standards and procedures for year-round water conservation, to promote the efficient use
of water, to reduce or eliminate the waste of water in the City, to complement the City's water quality
regulations and urban runoff reduction efforts, and enable implementation of the City's water shortage
contingency measures. These water conservation programs already In place would result in further
protection of groundwater resources In the City. In addition, the General Plan Conservation & Open
Space Element includes policies 7.1 and 7.2 to conserve water resources including the production and
use of recycled water. Impacts regarding the groundwater supplies and recharge will be consistent with
the previously approved 2014-2021 Housing Element Initial Study and no new impacts will occur.
c, m) Substantially alter the existing drainage pattern of the site or area, including through the alteration
of the course of stream or river, in a manner which would result in substantial erosion or siltation on-or
off-site? Could the proposed project result in increased erosion downstream? Less than Significant
Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion: Wind and water both
cause erosion that could be deposited In local or regional washes and other water bodies. Due to the
urbanized nature of the City, future housing development will not substantially alter the drainage pattern
of the area, and will not result in substantial erosion or siltation on or off site or downstream. Future
housing development on the Opportunity Sites and other development constructed pursuant to General
Plan policies will be required to implement standard on-site drainage controls and storm water
conveyance devices to direct any drainage appropriately. Impacts related to erosion and siltation will be
less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not alter the existing drainage pattern of the site or area, including through the alteration of
the course of stream or river, in a manner which would result in substantial erosion or siltation on-or off-
site and will not result In increased erosion downstream beyond the previously approved 2014-2021
Housing Element. As mentioned In the previously approved 2014-2021 Housing Element Initial Study,
due to the urbanized nature of the City, future housing development will not substantially alter the
drainage pattern of the area, and will not result in substantial erosion or siltation on or off site or
downstream. Future housing development on the amended Opportunity Sites and other development
constructed pursuant to General Plan policies will be required to Implement standard on-site drainage
controls and storm water conveyance devices to direct any drainage appropriately. Impacts regarding
alteration of the existing drainage pattern of the site or area, Including through the alteration of the course
of stream or river, in a manner which would result in substantial erosion or siltation on-or off-site and
increased erosion downstream will be consistent with the previously approved 2014-2021 Housing
Element Initial Study and no new impacts will occur.
d-e, k-1, n-o, y) Substantially alter the existing drainage pattern of the site or area, including through the
alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff
in a manner which would result in flooding on-or off-site? Create or contribute runoff water which would
exceed the capacity of existing or planned storm water drainage systems or provide substantial additional
sources of polluted runoff? Result in an increase in pollutant discharges to receiving waters? Consider
water quality parameters such as temperature, dissolved oxygen, turbidity and other typical storm water
pollutants (e.g. heavy metals, pathogens, petroleum derivatives, synthetic organics, sediments, nutrients,
oxygen-demanding substances, and trash) Result in significant alteration of receiving water quality
during or following construction? Result in increased impervious surfaces and associated increased
runoff? Create significant changes in the flow velocity or volume of stormwater runoff to cause
environmental harm? Create a significant adverse environmental impact to drainage patterns due to
changes in runoff flow rates or volumes? Less than Significant Impact. Previously Approved 2014-2021
Housing Element Initial Study Conclusion: The majority of San Juan Capistrano Is occupied by urban
uses, with drainage infrastructure well established. No subdivisions are proposed or facilitated through
Initial Study/Environmental Checklist -75-City of San Juan Capistrano, California
the updated Housing Element policy, General Plan and Zoning Code Amendments, Density Bonus
Program Update, or rezoning of Opportunity Sites (#5, #6, #7) which could affect existing streams or
rivers. Residential development typically does not generate significant water pollutants through point
discharges but does contribute to water quality impacts due to community-wide and regional urban runoff.
However, four of the eight identified Opportunity Sites are currently developed with predominately
impervious materials. As such, surface run-off from new development is not anticipated to substantially
increase. In addition, all new housing or redevelopment projects will be required to construct the
necessary drainage improvements to adequately accommodate any additional runoff, in compliance with
existing City requirements. The proposed General Plan Amendments associated would not permit
specific new development or induce growth. Thus, the Amendments would not create or contribute to
water runoff water. Impacts will be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not substantially increase the rate or amount of surface runoff in a manner which would
result in flooding on-or off-site, create or contribute runoff water which would exceed the capacity of
existing or planned storm water drainage systems or provide substantial additional sources of polluted
runoff, result in an increase in pollutant discharges to receiving waters, result in significant alteration of
receiving water quality during or following construction, result in increased impervious surfaces and
associated increased runoff, create significant changes in the flow velocity or volume of stormwater runoff
to cause environmental harni, or create a significant adverse environmental impact to drainage patterns
due to changes in runoff flow rates or volumes beyot:Jd the previously approved 2014-2021 Housing
Element.
The majority of San Juan Capistrano is occupied by urban uses, with drainage infrastructure well
established. No subdivisions are proposed or facilitated through the updated Housing Element policy,
General Plan Amendment, or rezoning of Opportunity Site #11 (City Hall) which could affect existing
streams or rivers. Residential development typically does not generate significant water pollutants
through point discharges but does contribute to water quality impacts due to community-wide and
regional urban runoff. However, three of the eleven amended Opportunity Sites (City Hall, C. Romer
Homestead, and Calle Lorenzo) are currently developed with predominately impervious materials. As
such, surface run-off from new development is not anticipated to substantially increase on these sites. In
addition, all new housing or redevelopment projects will be required to construct the necessary drainage
improvements to adequately accommodate any additional runoff, in compliance with existing City
requirements. The proposed General Plan Amendment would not permit specific new development.
Impacts will be consistent with the previously approved 2014-2021 Housing Element Initial Study and no
new impacts will occur.

have the potential to otherwise degrade water quality and groundwater quality beyond those issues
discussed in Sect ion 16.9 herein. The proposed project will not contribute to an exceeded applicable
surface or groundwater receiving water quality objective or degradation of beneficial uses. The proposed
General Plan Amendments do not authorize construction or redevelopment of any particular project, and
would not result in any new or more extensive sources of water pollutants. The proposed project will not
result in any violation of applicable water quality standards established by the Clean Water Act and
implemented by the San Diego Regional Water Quality Control Board (RWQCB) through the regional
National Pollution Discharge Elimination System (NPDES) permit. No impact will occur.

Housing Element Initial Study and no new impacts will occur.
i) Expose people or structures to a significant risk of Joss, injury or death involving flooding, including
flooding as a result of the failure of a levee or dam? Less than Significant. Previously Approved 2014-
2021 Housing Element Initial Study Conclusion: Implementation of the proposed Housing Element
Update does not propose the actual development of housing and thus would not expose people or
structures to hazards involving flooding or the failure of a levee or dam . However, the General Plan
Safety Element states that portions of the City are subject to potential risk of hazards associated with
failure of the Trampas Canyon Dam , located two miles east of the City limits within a tributary of San Juan
Creek . In addition, San Juan Capistrano contains three major creeks , San Juan Creek, Trabuco Creek,
and Oso Creek carrying water runoff from the hills northeast of the City to the Pacif ic Ocean in the south.
Trabuco Creek traverses a portion of Op portunity Site #5 and San Juan Creek is adjacent to Opportunity
Site #7.5° Flood hazards are addressed in the General Plan and Municipal Code. The City 's Municipal
Code includes Floodplain Management Regulations (Title 8, Chapter 11) and the Floodplain Management
Initial Study/Environmental Checklist -77-City of San Juan Capistrano, California

2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not expose people or structures to a significant risk of loss, injury or death involving flooding,
including flooding as a result of the failure of a levee or dam beyond the previously approved 2014-2021
Housing Element. Implementation of the Amended 2014-2021 Housing Element does not propose the
actual development of housing and thus would not expose people or structures to hazards involving
flooding or the failure of a levee or dam. However, as mentioned in the previously approved 2014-2021
Housing Element, the General Plan Safety Element states that portions of the City are subject to potential
risk of hazards associated with failure of the Trampas Canyon Dam, located two miles east of the City
limits within a tributary of San Juan Creek. In addition, San Juan Capistrano contains three major creeks,
San Juan Creek, Trabuco Creek, and Oso Creek carrying water runoff from the hills northeast of the City
to the Pacific Ocean in the south . Trabuco Creek traverses a portion of The Groves Opportunity Site (#4)
and San Juan Creek is adjacent to the Ventanas Opportunity Site (#5). Flood hazards are addressed in
the General Plan and Municipal Code. The City's Municipal Code includes Floodplain Management
Regulations (Title 8, Chapter 11) and the Floodplain Management Environmental Overlay District (Title 9,

with the previously approved 2014-2021 Housing Element Initial Study and no new impacts will occur.
j) Inundation by seiche, tsunami, or mudflow? Less than Significant. Previously Approved 2014-2021
Housing Element Initial Study Conclusion: A tsunami is a large wave that generates in the ocean,
generally from an earthquake, and builds intense strength and height before impacting a coast. The City
is protected from tsunamis due to its inland location. A seiche is the process by which water sloshes
outside its containing boundaries, generally due to an earthquake. This generally occurs with uncovered,
above-ground reservoirs. The City's reservoirs and swimming pools are enclosed bodies of water that are
subject to seiches during earthquakes. Mudflows require a slope, water, and unconsolidated soil to occur.
The terrain of San Juan Capistrano consists predominantly of gently to steeply rolling hills containing
deep-cut canyons and gullies. The City contains more than 600 feet of vertical relief. Furthermore, the
abundant shales and siltstones underlying the hills of San Juan Capistrano are highly porous and do not
hold together well when wet, which can lead to slope instability and landslides. The Opportunity Sites and
their surroundings do not contain steep slopes. Impacts will be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not expose people or structures to inundation by seiche, tsunami, or mudflow beyond the
previously approved 2014-2021 Housing Element. According to the previously approved 2014-2021
Housing Element Initial Study, the City is protected from tsunamis due to its inland location. The amended
Opportunity Sites and their surroundings do not contain steep slopes conducive to mudflows. However,
the City's reservoirs and swimming pools are enclosed bodies of water that are subject to seiches during
earthquakes. Impacts related to seiche, tsunami, or mudflow will be consistent with the previously
approved 2014-2021 Housing Element Initial Study and no new impacts will occur.

Fundamentals of Sound and Environmental Noise
The primary sources of noise affecting San Juan Capistrano are the various modes of transportation.
Because the City is bounded by three freeways and divided by various north-south and east-west arterial
streets, most areas of San Juan Capistrano are affected by traffic noise.
Noise is generally defined as unwanted sound. Sound (and therefore noise) consists of energy waves
that people receive and interpret. Sound pressure levels are described in logarithmic units of ratios of
sound pressures to a reference pressure, squared. These units are called bets. In order to provide a finer
description of sound, a bel is subdivided into ten decibels, abbreviated dB. To account for the range of
sound that human hearing perceives, a modified scale is utilized known as the A-weighted decibel (dBA).
Since decibels are logarithmic units, sound pressure levels cannot be added or subtracted by ordinary
arithmetic means. For example, if one automobile produces a sound pressure level of 70 dBA when it
passes an observer, two cars passing simultaneously would not produce 140 dB. In fact, they would
combine to produ ce 73 dBA. This same principle can be applied to other traffic quantities as well. In other
words, doubling the traffic volume on a street or the speed of the traffic will increase the tra ffic noise level
by 3 dBA. Conversely, halving the traffic volume or speed will reduce the traffic no ise level by 3 dBA. A 3
dBA change in sound is the level where humans generally notice a barely perceptible change in sound
and a 5 dBA change is generally readily perceptible. 54
Noise consists of pitch, loudness, and duration; therefore, a variety of methods for measuring noise has
been developed. According to the California General Plan Guidelines for Noise Elements, the following
are common metrics for measuring noise:55
LeQ (Equivalent Energy Noise Level): The sound level corresponding to a steady-state sound level
containing the same total energy as a time-varying signal over given sample periods. LEQ is typically
computed over 1-, 8-, and 24-hour sample periods.
CNEL (Community Noise Equivalent Level): The average eq uival ent A-weighted sound level during a
24-hour day, obtained after addition of five decibels to sound leve ls in the even in g from 7:00 P.M . to
Initial Study/Environmental Checklist -84-City of San Juan Capistrano, California
10:00 P.M. and after addition of ten decibels to sound levels in the night from 10:00 P.M. to 7:00A.M.
LoN (Day-Night Average Level): The average equivalent A-weighted sound level during a 24-hour day,
obtained after the addition of ten decibels to sound levels in the night after 1 O:OOpm and before 7:00am.
,CNEL and LoN are utilized for describing ambient noise levels because they account for all noise sources
over an extended period of time and account for the heightened sensitivity of people to noise during the
night. Leo is better utilized for describing specific and consistent sources because of the shorter reference
period .
Fundamentals of Environmental Groundborne Vibration
Vibration is sound radiated through the ground. The rumbling sound caused by the vibration of room
surfaces is called groundborne noise. The ground motion caused by vibration is measured as particle
velocity in inches per second, and in the U.S . is referenced as vibration decibels (VdB).
The background vibration velocity level in residential and educational areas is usually around 50 VdB.
The vibration velocity level threshold of perception for humans is approximately 65 VdB. A vibration
velocity level of 75 VdB is the approximate dividing line between barely perceptible and distinctly
perceptible levels for many people . Sources within buildings such as operation of mechanical equipment,
movement of people, or the slamming of doors causes most perceptible indoor vibration. Typical outdoor
sources of perceptible groundborne vibration are construction equipment, steel-wheeled trains, and traffic
on rough roads . If a roadway is smooth, the groundborne vibration from traffic is rarely perceptible. The
range of interest is from approximately 50 VdB, which is the typical background vibration velocity level,
and 100 VdB, which is the general threshold where minor damage can occur in fragile buildings. The
general human response to different levels of groundborne vibration velocity levels is described in Table 8
(Human Reaction to Groundborne Vibration).

a) Exposure of persons to or generation of noise levels in excess of standards established in the local
general plan or noise ordinance, or applicable standards of other agencies? Less than Significant
Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion: The primary
contributor to ambient noise in the planning area is traffic, particularly from Interstate 5 and the Ortega
Highway. As detailed in the General Plan, since a minimal amount of development is possible within the
City, a minimal amount of traffic and traffic noise is expected on the major roads that could impact existing
or future residential uses or other noise sensitive uses. The San Juan Capistrano General Plan identifies
standards for land uses and noise compatibility, as summarized in Table 9 (Interior and Exterior Noise
Standards). In addition, Section 9-3 .531 of the Municipal Code establishes additional time of day based
land use noise standards as shown in Table 10 (Municipal Code Exterior Noise Standards). Table 11
shows the Maximum Noise Level Not to be Exceeded During a Period of Time pursuant to Municipal
Code Sec.9-3.531 .

Initial Study/Environmental Checklist -86-City of San Juan Capistrano, California
The proposed General Plan amendments will increase maximum residential densities to 30 dwelling units
per acre in the Very High Density zones, in excess of those analyzed by the General Plan EIR. However,
as discussed in Section 16.3, Air Quality, the proposed General Plan amendments will be consistent with
growth SCAG growth projections and will therefore not result in any substantial traffic or other noise
sources as analyzed in the General Plan EIR. Future housing developments on the proposed Opportunity
Sites and in other areas of the City are subject to the policies of the existing General Plan designed to
minimize noise impacts to residential properties. The following noise policies of the General Plan will be
implemented during the City's standard environmental review process during the entitlement process for
future housing developments. Impacts to residential development related to noise levels in excess of
established standards and permanent increases in ambient noise levels will be less than significant with
implementation of the noise policies of the General Plan.
General Plan Policies
Noise Goal 1: Minimize the effects of noise through proper land use planning .
Policy 1.1: Utilize noise/land use compatibility standards as a guide for future planning and
development decisions.
Policy 1.2: Provide noise control measures and sound attenuating construction in areas of new
construction or rehabilitation.
Noise Goal 2: Minimize transportation-related noise impacts.
Policy 2.1: Reduce transportation-related noise impacts to sensitive land uses through the use of
noise control measures.
Policy 2.2: Control truck traffic routing to reduce transportation-related noise impacts to sensitive land
uses.
Policy 2.3: Incorporate sound-reduction design in development projects impacted by transportation-
related noise.
Policy 2.4: Oppose airport operations that will result in excessive noise from overflights.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in exposure of persons to or generation of noise levels in excess of standards
established in the local general plan or noise ordinance, or applicable standards of other agencies
beyond the previously approved 2014-2021 Housing Element. As discussed in Section 16.3, Air Quality,
the proposed General Plan amendment will be consistent with growth SCAG growth projections and will
therefore not result in any substantial traffic or other noise sources as analyzed in the General Plan EIR.
Future housing developments on the amended Opportunity Sites and in other areas of the City are
subject to the policies of the existing General Plan designed to minimize noise impacts to residential
properties. As mentioned in the previously approved 2014-2021 Housing Element Initial Study, the noise
policies of the General Plan will be implemented during the City's standard environmental review process
during the entitlement process for future housing developments. Impacts related to exposure of persons
to or generation of noise levels in excess of standards established in the local general plan or noise
ordinance will be consistent with the previously approved 2014-2021 Housing Element Initial Study and
no new impacts will occur.
b) Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels?
Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study
Conclusion: Groundborne vibration can result in impacts from minor annoyances to people to major
shaking that damages buildings. There are no railways within the City. The primary source of
groundborne vibration within the City would be heavy construction activities. According to the Caltrans
Initial Study/Environmental Checklist -87-City of San Juan Capistrano, California
Transportation-and Construction-Induced Vibration Guidance Manual, transportation sources are not a
significant source of vibration and therefore are not discussed below.
Groundborne vibration generated by construction projects is usually highest during pile driving, rock
blasting, soil compacting, jack-hammering, and demolition-related activities. Next to pile driving, grading
activity has the greatest potential for vibration impacts if large bulldozers or large trucks are used.
Housing does not utilize machinery that would generate substantial amounts of vibration. The
construction of future potential housing developments could utilize machinery that would generate
substantial amounts of ground vibration because multiple-lot housing developments generally require
mass grading. Construction of future development is not likely to require rock blasting considering the
built-out character of the area or piling driving because the Opportunity Sites are generally not subject to ·
liquefaction hazards; however, jack hammering will also likely be required for demolition activities. Table
12 (Common Construction Vibration) summarizes vibration levels from common construction equipment.
Impacts to structures can occur from 0.08 PPV to 2.00 PPV depending on the duration of the vibration
and the age of the structure. Similarly, human annoyance to vibration can occur from 0 .01 PPV to 2.00
PPV depending on the duration.

Vibration impacts are temporary and rare except in cases where large equipment is used near existing,
occupied development. Construction noise and associated vibration will be controlled through the time
restrictions currently established in the City's Noise Control requirements. Section 9-3.531 of the
Municipal Code exempts noise sources associated with construction, repairs, remodeling, or the grading
of any real property, except that such activities shall not be exempt from the provisions of this section if
conducted from 6:00 p.m . to 7:00 a.m . on Monday through Friday, or from 4:30 p.m. to 8:30 a .m . on
Saturday, or at any time on Sunday or a national holiday. As such construction is exempted from noise
standards, construction is typically required to be performed within these hours to not potentially conflict
with normal noise standards. Therefore, potential construction related vibration impacts would be
minimized to daytime hours. Per standard practice and City policy for noise analysis, future development
projects that utilize vibration inducing equipment, in particular when located near sensitive uses/buildings,
will be analyzed individually for potential vibration impacts . Typical vibration mitigation includes routing
and placement of equipment to maximize distance to receptors and use of alternative equipment, such as
use of drilled, sonic, or vibratory pile drivers as opposed to impact drivers. Subsurface dampeners can
also be utilized to reduce groundborne vibration. With implementation of existing regulations, policies, and
practices, impacts related to exposure to groundborne vibration will be less than significant. No impacts
would be associated with vibration from rail lines or construction as associated with General Plan
amendments to the Land Use and Safety Elements, as no policy changes, developments, or
infrastructure improvements are proposed .
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in the exposure of persons to or generation of excessive groundborne vibration or
groundborne noise levels beyond the previously approved 2014-2021 Housing Element. Housing does
not utilize machinery that would generate substantial amounts of vibration . The construction of future
potential housing developments could utilize machinery that would generate substantial amounts of
ground vibration because multiple-lot housing developments generally require mass grading. As
mentioned in the previously approved 2014-2021 Housing Element Initial Study, construction no ise and

associated vibration will be controlled through the time restrictions currently established in the City's
Noise Control requirements. Section 9-3.531 of the Municipal Code exempts noise sources associated
with construction , repairs, remodeling , or the grading of any real property, except that such activities shall
not be exempt from the provisions of this section if conducted from 6:00 p.m . to 7:00 a.m. on Monday

consistent with the previously approved 2014-2021 Housing Element Initial Study and no new impacts will
occur.
c) A substantial permanent increase in ambient noise levels in the project vicin ity above levels existing
without the project? Less than Significant Impact. Previously Approved 2014-2021 Housing Element
Initial Study Conclusion: Residential land uses do not typically produce excessive noise either
individually or cumulatively that could substantially increase existing, ambient noise levels. The future
development of the Opportunity Sites will increase ambient noise levels due to increased traffic
genera ti on in the project vici ni ty . The identif ie d Opportu nity Sites are ant icipate d to gen erate a total of
approx ima tely 5,440 daily vehicle trips.56 T hus , develo pment of the Opportun ity Sites wo ul d partially
contribute to the noise volumes identified in the General Plan EIR. The Housing Element does not
propose any specific development or any land use changes that would invalidate this prior finding or
further increase traffic levels beyond those analyzed in the General Plan EIR. Project specific increases in
ambient noise levels due to future deve lopment on each Opportunity Site will be evaluated as
development is proposed over the long-term pursuant to existing policies and procedures. With these
existing policies and procedures, impacts related to increases in ambient noise levels will be less than
significant. No new development or changes to policy are proposed through the other General Plan
amendments, and no impacts would occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in a substantial permanent increase in ambient noise levels in the project vicinity
above levels existing without the project beyond the previously approved 2014-2021 Housing Element.
Residential land uses do not typically produce excessive noise either individually or cumulatively that
could substantially increase existing , ambient noise levels . The future development of the Amended
Opportunity Sites will increase ambient noise levels due to increased traffic generation in the project
vicinity. As mentioned in the previously approved 2014-2021 Housing Element Initial Study, the
Opportunity Sites are anticipated to generate daily vehicle trips . Therefore, development of the Amended
Opportunity Sites would partially contribute to the noise volumes identified in the General Plan EIR. The
2014-2021 Housing Element Adendum does not propose any specific development or any land use
changes that would invalidate this prior finding or further increase traffic levels beyond those analyzed in
the General Plan EIR. Project specific increases in ambient noise levels due to future development on
each Amended Opportunity Site will be eva luated as development is proposed over the long-term
pursuant to existing policies and procedures . With these existing policies and procedures , impacts related
to increases in ambient noise levels will be less than significant. Impacts related to permanent increases
in ambient noise levels will be consistent with the previously approved 2014-2021 Housing Element Initial
Study and no new impacts will occur .
d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels
existing without the project? Less than Significant Impact. Previously Approved 2014-2021 Housing
Element Initial Study Conclusion: The updated General Plan Amendments do not authorize the
development or redevelopment of any particular site but do include policies that could facilitate
development of future housing . Temporary increases in local noise levels would be associated with
Initial Study/Environmental Checklist -89-City of San Juan Cap is trano, California
construction activities to develop new housing. Construction noise will be controlled through the time
restrictions currently established in the City's noise control requirements. The updated Housing Element
would not result in any new or more severe temporary noise impacts associated with residential
construction. Continued enforcement of the City's noise restrictions will reduce temporary noise impacts
associated with the General Plan Amendments to a less-than-significant level.

e, f) For a project located within an airport land use plan or, where such a plan has not been adopted,
within two miles of a public airport or public use airport, would the project expose people residing or
working in the project area to excessive noise levels? For a project within the vicinity of a private airstrip,

Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion: Adoption
and implementation of the Housing Element will not directly result in population growth. Population growth
is a complex interaction among immigration, emigration, birth, deaths, and economic factors. The
proposed Housing Element is designed to guide and accommodate the inevitable population growth the
community will face over the short and long term. The Census reported the City had a population of
33,826 in 2000 and 34,593 as of 2010, which would represent an approximately 2.27 percent increase.
SCAG 's Regional Transportation Plan/Sustainable Communities Strategy (RTP/SCS) estimated a 2008
population for San Juan Capistrano of 34,400 and projects an estimated population of 38,100 and 37 ,800
by 2020 and 2035, respectively.
The Opportunity Sites identified in the Housing Element would result in an increase of approximately 807
new dwelling units and approximately 2,413 new residents (807 dwelling units at 2.99 persons per
household). This increase is within the growth assumptions estimated by SCAG and therefore will
adequately accommodate future residential growth. In addition, the proposed Housing Element and
Opportunity Sites are projected to meet the City's RHNA (638 units), which is correlated with the City's
long-term growth projected by SCAG. Impacts will be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Hous ing
Element Opportunity Sites will not induce substantial population growth in an area beyond the previously
approved 2014-2021 Housing Element. According to the previously approved 2014-2021 Housing
Element Initial Study, adoption and implementation of the Housing Element will not directly result in
populat ion growth . The Census reported the City had a population of 33 ,826 in 2000 and 34,593 as of
2010 , which would represent an approx imately 2.27 percent increase . SCAG's Regional Transportation
Plan/Sustainable Communities Strategy (RTP/SCS) estimated a 2008 population for San Juan
Capistrano of 34,400 and projects an estimated population of 38,100 and 37,800 by 2020 and 2035,
respectively.
The 2014-2021 Housing Element Initial Study Addendum identifies eleven opportunity sites for future
residential development. The new Opportunity Sites could result in approximately 772 new dwelling units
and 2,238 new residents (772 dwelling units at 2.9 persons per household). SCAG provides population
projection estimates in five-year increments from 2005 to 2035. According to the latest growth forecast
(2012), SCAG estimates that the City would have a population of 37,800 in 2035. This increase is within
the growth assumptions estimated by SCAG and therefore will adequately accommodate future
residential growth . In addition, the 2014-2021 Housing Element Addendum and Opportunity Sites are
projected to meet the City's RHNA (638 units), which is correlated with the City's long-term growth
projected by SCAG . Impacts related to substantial population growth in an area will be consistent with the
previously approved 2014-2021 Housing Element Initial Study and no new impacts will occur.

b) Displace substantial numbers of existing housing, necessitating the construction of replacement
housing elsewhere? Less than Significant Impact. Previously Approved 2014-2021 Housing Element
Initial Study Conclusion: The proposed Housing Element is designed to encourage and facilitate housing
development and preserve and enhance existing housing stock. San Juan Capistrano is urbanized and is
primarily bu ilt out. There are few vacant parcels and some underutilized properties that may be recycled
for the purpose of new housing and mixed-use development. This natural recycling of land will not result
in the loss of housing units because such redevelopment will result in the development of new housing
units. The Opportunity Sites identified in the proposed Housing Element are either vacant or
underutilized. However, Opportunity Sites 1, 3, 6, and 9 each has either single-family or multi-family
development constituting a total of approximately 46 dwelling units. Goal 1 of the Housing Element
encourages maintenance and preservation of the existing housing stock; therefore, future development
and redevelopment of Opportunity Sites and other housing development constructed pursuant to the
Housing Element update will have less than significant impacts on the City's existing housing stock.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not displace substantial numbers of existing housing beyond the previously approved 2014-
2021 Housing Element. As mentioned in the previously approved 2014-2021 Housing Element, the
proposed Housing Element is designed to encourage and facilitate housing development and preserve
and enhance existing housing stock . San Juan Capistrano is urbanized and is primarily built out. There
are few vacant parcels and some underutilized properties that may be recycled for t he purpose of new
hous ing and mixed-use development. This natural recycling of land will not result in the loss of housing
units beca use such redevelopment will result in the development of new hous ing units . The Amended
Opportunity Sites identified in the proposed Housing Element are either vacant or underutilized. However,
existing housing units are present on several of the Amended Opportunity Sites. Goal 1 of the Housing
Element encourages maintenance and preservation of the existing housing stock; therefore, future
development and redevelopment of Amended Opportunity Sites and other housing deve lopment
constructed pursuant to the Housing Element update will have less than significant impacts on the City 's
existing housing stock. Impacts related to displacement of housing will be consistent with the previously
approved 2014-2021 Housing Element Initial Study and no new impacts will occur.
c) Displace substantial numbers of people, necessitating the construction of replacement housing
elsewhere? Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial
Study Conclusion: The proposed Housing Element will not displace any people because the project does
not authorize the demolition or conversion of any housing unit. Although housing units do currently exist
on several of the Opportunity Sites, the Housing Element does not authorize the acquisition of any
existing residential dwelling unit. New housing, if constructed on these sites, will produce more units than
exist today, providing greater opportunities for people to purchase or rent homes in San Juan Capistrano.
The impact will be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not displace substantia l numbers of people, necessitating the construction of replacement
housing elsewhere beyond the previously approved 2014-2021 Housing Element. The 2014-2021
Housing Element Addendum will not displace any people because the project does not authorize the

Approved 2014-2021 Housing Element Initial Study Conclusion: The updated San Juan Capistrano
Housing Element sets forth policies and programs to encourage housing development consistent with
adopted General Plan land use polices. Residential development constructed pursuant to Housing
Element policy will incrementally increase the need for fire and police protection, schools, and parks.
SCAG estimates that the City 's population will be 37,800 in 2035. The Housing Element's goal to facilitate
807 very low-to above moderate-income units by 2021 would increase the local housing stock from
11,940 units as of 2010 (2010 Census count) to 12,747 units, and would increase the resident population
by approximately 2,413 persons (807 dwelling units at 2.99 persons per household). The other proposed
General Plan and Zoning Code amendments relating to the maximum residential density increase and
update to the Density Bonus Program do not change any applicable land use designations and do not
propose or anticipate any specific development proposals or infrastructure projects . Therefore, these
amendments will not result in any impacts that were not addressed in the General Plan EIR. The General
Plan EIR indicates that build out of the land use plan would result in less than significant impacts to parks,
schools, fire, or police services.
Parks
According to San Juan Capistrano's parkland standard, there is an existing surplus of approximately five
acres in the City. 58 The City requires a parkland dedication of five acres per 1 ,000 residents or an in-lieu
fee payment as a required condition for approval of a residential subdivision Section 9-5.107 (Parkland in-
lieu fee). Site #8 (Regional Occupational Program Downtown Parcel) is currently designated as General
Open Space by the General Plan Land Use Map. The site contains a baseball diamond and is directly
north of the San Juan Elementary School. The potential conversion of this site from General Open Space
to residential use would . comply with the Quimby Act as well as General Plan goals and policies. The
developer of the site would have to pay an in-lieu fee if the minimum five acres of park per 1,000
residents is not provided to offset incremental impacts of development on existing parks. Any future
housing development will be required to pay development impact fees in accordance with this existing
regulation; thus deterioration of existing parks and recreation facilities will be less than significant as a
result of future housing development because parks and recreation facilities will be incrementally
expanded to meet future residential demand. The following General Plan policies and implementation
measures will assist in reducing the impact on parks.
Parks & Recreation Goal 1: Provide, develop, and maintain ample park and recreational facilities that

Policy 1.8: Publicize park and recreation opportunities in San Juan Capistrano to the community.
Policy 1.9: Utilize existing public utility easements for recreation and open space.
Schools
Any impact on the provision of school services is mitigated through the payment of development impact
fees pursuant to the Leroy F. Green School Facilities Act. With payment of required fees, impact will be
less than significant.
Fire and Police
Future potential plans for development and redevelopment will be reviewed by City staff to determine any
impacts of devel opment on emergency servi ces and are al so subj ect to revie w by San Juan Cap istran o's
Pol ice De partme nt and th e Orange Co unty Fire A uth ority for compliance with app lica ble standard s and
po li c ies. Future potent ial plans f or devel op ment are also subject to the poli c ie s of the General Plan Safety
Element. The Safety Element and Public Services & Utilities Element policies are designed to ensure
adequate provision of public services in response to long-term growth. Property taxes and other special
taxes paid by future property owners will also support the incremental expansion of public services as the
population in the City grows. Impacts to public services will be less than significant.
General Plan Policies

to reduce the risk of criminal actfvity.
Policy 3.4: Improve public awareness of both the responsiveness of the Orange County Sheriff's
Department and ways to reduce criminal activity within the City.
Libraries
Prior to future development, consultation with library system officials would be required to ensure that
existing facilities will be sufficient to provide library services to additional residents. Such consultation will
provide for any impacts to be addressed and mitigated at the time a development proposal is put forward.
Public Services & Utilities Goal 5: Work with the Orange County Public Library to provide a sufficient level
of library facilities and services.
Policy 5.1: Work closely with the Orange County Public Library in determining and meeting community
needs for library facilities and services, including hours of operation.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result impacts to public facilities and services such as parks, schools, fire, police, or
libraries beyond the previously approved 2014-2021 Housing Element. According to the previously
approved 2014-2021 Housing Element Initial Study, residential development constructed pursuant to
Housing Element policy will incrementally increase the need for fire and police protection, schools, and
parks . SCAG estimates that the City's population will be 37,800 in 2035. The Amended Housing
Element's goal to facilitate 772 very low-to above moderate-income units by 2021 would increase the
local housing stock from 11 ,940 units as of 2010 (201 0 Census count) to 12,712 units, and would
increase the resident population by approximately 2,238 persons (772 dwelling units at 2.9 persons per
household). The General Plan amendment will not result in any impacts that were not addressed in the
General Plan EIR. The General Plan EIR indicates that build out of the land use plan would result in less
than significant impacts to parks, schools, fire, or police services.
Parks
As mentioned in the previously approved 2014-2021 Housing Element, any future housing development
that converts open space to residential use will be required to pay development impact fees in
accordance with the Quimby Act; thus deterioration of existing parks and recreation facilities will be less
than significant as a result of future housing development because parks and recreation facilities will be
incrementally expanded to meet future residential demand . In addition, as mentioned in the previously
approved 2014-2021 Housing Element, General Plan policies and implementation measures will assist in

Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion : As discussed in
Section 16.14.d, the project has the potential to result in the indirect need for recreational facilities by
promoting housing development. Site #8 (Regional Occupational Program Downtown Parcel) is currently
designated as General Open Space by the General Plan Land Use Map. The site contains a baseball
diamond and is directly north of the San Juan Elementary School. The potential conversion of this site
from General Open Space to residential use would comply with the Quimby Act as well as General Plan

development impact fees in accordance with this existing regulation; thus deterioration of existing parks
and recreation facilities will be less than significant as a result of future housing development because
parks and recreation facilities will be incrementally expanded to meet future residential demand. The
other proposed General Plan Amendments related to the maximum residential density increase pertain to
recreation because increased density could increase the use of existing park facilities. However, no land
use changes or infrastructure projects are proposed and no changes to parkland are proposed .
Therefore , these amendments will not result in any impacts that were not addressed in the General Plan
EIR.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not increase the use of existing neighborhood and regional parks or other recreational
facilities such that substantial physical deterioration of the facility would occur or be accelerated beyond
the previously approved 2014-2021 Housing Element. As mentioned in the previously approved Housing

Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study
Conclusion: Devel opment of housing on the propo sed Op portunity Sites would result in approx ima tely
5,44 0 dail y trips at build -out based on the Institute of T raffic Engineers (ITE) 8th Editi on Trip Generation
manual. (This calculation does not account for any discount on trips associated with existing uses on the
Opportunity Sites .) SCAG estimates that the City's population will be 37,800 in 2035 . The Housing
Element's goal to facilitate 807 very low-to above moderate-income units by 2021 would increase the
local housing stock from 11,940 units as of 2010 (2010 Census count) to 12,747 units, and would
increase the resident population by approximately 2,413 persons (807 dwelling units at 2.99 persons per
household). The increase in population would not exceed 2012-2035 Regional Transportation Plan
population growth projections . The proposed Opportun ity Sites would implement the General Plan Land
Use plan . The proposed General Plan Amendments would increase maximum residential density to 30
dwelling units per acre in the Very High Density zone; however, the proposed General Plan amendments
will be consistent with growth SCAG growth projections and will therefore not result in a substantial
increase in traffic than analyzed in the General Plan EIR. The Housing Element does not propose any
specific development that would invalidate this prior finding or significantly increase traffic levels beyond
those analyzed in the General Plan EIR. On an individual development basis, traffic assessments will be
required for all future residential development during the C ity 's standard environmental review process to
determine project specific traffic generation, traffic distribution, modal splits, impacted intersections and
roadways, project-specific fair-share improvement fees, and applicable regional transportation fees . The
other proposed General Plan Amendments relating to the maximum residential density increase and the
update of the Density Bonus Program do not propose or anticipate any specific development proposals or
Initial Study/Environmental Checklist -99-City of San Juan Capistrano, California
infrastructure projects. Therefore, these amendments will not result in any impacts that were not
addressed in the General Plan EIR. Impacts related to substantial traffic congestion will be less than
significant with implementation of the following General Plan policies.
General Plan Policies
Circulation Goal 1: Provide a system of roadways that meets the needs of the community.
Policy 1.1: Provide and maintain a City circulation system that is in balance with the land uses in San
Juan Capistrano.
Policy 1.2 : Implement the City's Master Plan of Streets and Highways.
Policy 1.3 : Coordinate improvements to the City circulation system with other major transportation
improvement programs.
Policy 1.4: Improve the San Juan Capistrano circulation system roadways in concert with land
development to ensure sufficient levels of service.
Policy 1.5: Improve existing arterial system that serves regional circulation ·patterns in order to reduce
local congestion (Ortega Highway at 1-5).
Policy 1.6: Reduce the congestion along local arterial roadways in commercial areas by driveway
access consolidation, parking area interconnections and similar actions.
2014-2021 Housing Element Initial Study Addendum Conclusion : The Amended 2014-2021 Housing
Element will not conflict with an applicable plan, ordinance or policy establishing measures of
effectiveness for the performance of the circulation system beyond the previously approved 2014-2021
Housing Element.
The 2014-2021 Housing Element Initial Study Addendum identifies eleven opportunity sites for future
residential development. The new Opportunity Sites could result in approximately 772 new dwelling units
and 2,238 new residents (772 dwelling units at 2.9 persons per household). SCAG provides population
projection estimates in five-year increments from 2005 to 2035. According to the latest growth forecast
(2012), SCAG estimates that the City would have a population of 37,800 in 2035.
The 2014-2021 Housing Element Addendum's goal to facilitate 772 very low-to above moderate-income
units by 2021 would increase the local housing stock from 11,940 units as of 2010 (201 0 Census count)
to 12,712 units, and would increase the resident population by approximately 2,238 persons (772 dwelling
units at 2.99 persons per household).The increase in population would not exceed 2012-2035 Regional
Transportation Plan population growth projections.
The Housing Element does not propose any specific development that would invalidate this prior finding
or significantly increase traffic levels beyond those analyzed in the General Plan EIR. On an individual
development basis, traffic assessments will be required for all future residential development during the
City's standard environmental review process to determine project specific traffic generation , traffic
distribution, modal splits , impacted intersections and roadways, project-specific fair-share improvement
fees, and applicable regional transportation fees. Impacts related to an applicable plan, ordinance or
policy establishing measures of effectiveness for the performance of the ci rculation system will be
consistent with the previously approved 2014-2021 Housing Element Initial Study and no new impacts will
occur.
b) Conflict with an applicable congestion management program, including, but not limited to level of
service standards and travel demand measures, or other standards established by the county
congestion/management agency for designated roads or highways? Less than Significant Impact.

Management Program (CMP) is administered by the Orange County Transportation Authority (OCT A).
The CMP establishes a service goal of LOS E or better on all CMP roadway segments. There are two
CMP intersections within the City: I - 5 NB Ramps/Ortega Highway3 and I -
5 SB Ramps/Ortega Highway. Any future housing development would be required to have prepared a
traffic impact analysis (TIA) if such project would generate 2,400 or more daily trips . For developments
that will directly access a CMP Highway System link, a TIA is required if it will result in 1,600 or more daily
trips. As identified in Section 4.15.a above, the proposed Housing Element would result in 5,440 trips.
For individual development projects, the City will determine if a traffic impact analysis is required as part
of the City's standard environmental review process and determine potential future impacts to CMP
facilities. The proposed General Plan Amendments would not alter any land use that could increase
development intensity that could potentially create a greater impact than was already analyzed by the
General Plan EIR No specific development proposals or infrastructure projects are proposed. Therefore,
these amendments will not result in any impacts that were not addressed in the General Plan EIR
Impacts related to level of service standards on CMP facilities will be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not conflict with an conflict with an applicable congestion management program beyond the

consistent with the previously approved 2014-2021 Housing Element Initial Study and no new impacts will
occur.
c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in
location that results in substantial safety risks? No Impact. Previously Approved 2014-2021 Housing
Element Initial Study Conclusion: The updated Housing Element is focused on achieving local housing
objectives and does not authorize any construction that would result in the need to redirect or otherwise
alter air traffic patterns. The proposed General Plan and Zoning Code amendments are intended to
increase the maximum residential density and do not authorize specific construction or infrastructure
projects. Furthermore, the proposed General Plan Amendments will not result in substantial population
growth that could significantly increase air traffic. Therefore, the project will have no air traffic impacts .

No Impact. Previously Approved 2014~2021 Housing Element Initial Study Conclusion: The City of San
Juan Capistrano's Sewer and Wastewater Division is responsible for maintaining the City's sewer
collection system . The City's sewer is collected and treated at the South Orange County Wastewater
Authority's (SOCWA) JB Latham treatment plan and then discharged into the ocean. Wastewater
treatment requirements for the Orange County Sanitation District treatment facilities are established by
the Santa Ana Regional Water Quality Control Board (RWQCB). These treatment requirements establish
pollutant limits for effluent discharges to receiving waters . Future housing development will result in
typical residential wastewater discharges and will not require new methods or equipment for treatment
that are not currently permitted for existing treatment plants. Furthermore, residential development is not
subject to point-source discharge requirements. The project will not impact compliance with RWQCB
treatment requirements. Future housing development will not interfere with compliance with RWQCB
wastewater treatment requirements . The proposed General Plan and Zoning Code amendments will
increase the maximum residential density but do not propose or anticipate any specific development
proposals or infrastructure projects . Thus, no impact will occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not exceed wastewater treatment requirements of the applicable Regional Water Quality
Control Board beyond the previously approved 2014-2021 Housing Element. According to the previously
approved Housing Element In itial Study, future housing development will result in typical residential
wastewater discharges and will not require new methods or equipment for treatment that are not currently
permitted for existing treatment plants. Furthermore, residential development is not subject to point-
source discharge requirements. The project will not .impact compliance with RWQCB treatment
requirements. Future housing development will not interfere with compliance with RWQCB wastewater
treatment requirements . The proposed General Plan and Zoning Code amendments do not propose or

treatment requirements of the applicable Regional Water Quality Control Board will be consistent with the
previously approved 2014-2021 Housing Element Initial Study and no new impacts will occur.
b) Require or result in the construction of new water or wastewater treatment facilities or expansion of
existing facilities, the construction of which could cause significant environmental effects? Less than
Significant Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion: Future
housing development will incrementally increase water demand and wastewater discharges. The City
receives its water from three sources. Water is purchased from Metropolitan Water District of Southern
California (MWDSC). MWDSC's imported water sources are a blend of State Water Project water from
Northern California, and water from the Colorado River Aqueduct. Furthermore, the City is supplied with
treated water f.rom the Ground Water Recovery Plant and two potable production wells located in the
Northern portion of the City. Conservation of water resources became increasingly important throughout
Southern California in the 1980s and early 1990s, when the entire region suffered a severe drought. In
recognition of California's limited water supply, the City adopted a Water Conservation Ordinance
(Section 6-12.01). The ordinance places mandatory restrictions on water was.te at all times.
The proposed updated Housing Element and General Plan Amendments would alter residential land use
by increasing maximum residential density from 25 dwelling units per acre to 30 dwelling units per acre.
However, this increased density will not create a greater impact than was already analyzed by the
General Plan EIR. No additional water or wastewater facilities or expansions are proposed as part of the
General Plan Amendments. The City will identify the need for expansion of water and wastewater
facilities, such as water and sewer mains, as needed, on a project-by-project basis during its standard
environmental review process. Any environmental impacts related to the construction or expansion of
water or wastewater facilities will be analyzed and mitigated for at the time of development. Water
conservation programs already in place as well as General Plan policies would result in further protection
of ground water resources in San Juan Capistrano. Therefore, implementation of the proposed General
Plan and Zoning Code amendments would result in less than significant impacts.
General Plan Policies
Conservation & Open Space Goal 7: Protect water quality.
Policy 7.1: Coordinate water quality and supply programs with the responsible water agencies.
Policy 7.2: Encourage the production and use of recycled water .
Policy 7.3: Conserve and protect watershed areas.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not require or result in the construction of new water or wastewater treatment facilities or
expansion of existing facilities beyond the previously approved 2014-2021 Housing Element. As
mentioned in the previously approved 2014-2021 Housing Element Initial Study, future housing

c) Require or result in the construction of new stormwater drainage facilities or expansion of existing
facilities, the construction of which could cause significant environmental effects? Less than Significant
Impact. Previously Approved 2014-2021 Housing Element Initial Study Conclusion: The updated Housing
Element is focused on achieving local housing objectives and does not authorize any construction that
would result in the construction of new storm water drainage facilities or the expansion of existing
facilities. Drainage improvements are constructed on a project-by-project basis. This typically involves
routing a major drainage course through a project by concentrating the flow into an acceptable drainage
facility. Construction of drainage devices will be entirely on-site and will be subject to standard
construction requirements for erosion control and water quality requirements . Future housing
development will comply with existing standards and regulations for conveyance of storm water. The
proposed General Plan and Zoning Code Amendment will increase the maximum residential density. No
additional storm water drainage facilities or expansions are proposed as part of the General Plan
amendments. A less than significant impact to the environment from construction of storm drain
infrastructure will occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not require or result in the construction of new stormwater drainage facilities or expansion of

d) Have sufficient water supplies available to serve the project from existing entitlements and resources,
or are new or expanded entitlements needed? Less than Significant Impact. Previously Approved
2014-2021 Housing Element Initial Study Conclusion: The City is responsible for water distribution in San
Juan Capistrano and provides services throughout its fourteen square mile service area. The City
receives its water from two main sources, the San Juan Basin, which is managed by the San Juan Basin
Authority (SJBA) and imported water from the Municipal Water District of Orange County (MWDOC).
Groundwater is pumped from two domestic wells located throughout the City, and imported water is
treated at the Diemer Filtration Plant and is delivered to the City through two imported water connections.
Currently, the total water demand for the City is approximately 8,780 acre-feet annually consisting of
6,380 acre-feet of imported water, 1,980 of local groundwater, and 430 acre-feet of combined non-
domestic and recycled water. The City is projecting an increasing water demand trend of 18% in the next
25 years.59
The General Plan EIR determined that with the water conservation programs in place, there will be a less
than significant impact to water resources with General Plan build out. The proposed General Plan
Amendments would not alter any land use that could increase development intensity that could potentially
create a greater impact than was already analyzed by the General Plan EIR. The proposed General Plan
Amendments would not result in any population growth or additional demand on water supplies; rather,
the Amendments will guide development to accommodate anticipated population growth in the community
through the year 2021. Therefore, the proposed project would not result in the need for new or expanded
water supplies, nor revise any policies associated with water supply or demand, and impacts will be less
than significant.
Initial Study/Environmental Checklist -106-City of San Juan Capistrano, California
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing

e) Result in a determination by the wastewater treatment provider which serves or may serve the project
that it has adequate capacity to serve the project's projected demand in addition to the provider's existing
commitments? Less than Significant Impact. Previously Approved 2014-2021 Housing Element Initial
Study Conclusion: Wastewater treatment requirements are established by the Santa Ana RWQCB. The
City will review future development as part of the standard environmental review process to determine
adequate capacity to serve the discharge needs in comparison to treatment plant capacity. Impacts will
be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in inadequate wastewater treatment beyond the previously approved 2014-2021
Housing Element. As mentioned in the previously approved 2014-2021 Housing Element Initial Study,
wastewater treatment requirements are established by the Santa Ana RWQCB . The City will review future
development as part of the standard environmental review process to determine adequate capacity to
serve the discharge needs in comparison to treatment plant capacity. Impacts related to wastewater
treatment will be consistent with the previously approved 2014-2021 Housing Element Initial Study and no
new impacts will occur.
f) Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste
disposal needs? No Impact. Previously Approved 2014-2021 Housing Element Initial Study C.onclusion:
San Juan Capistrano is served by a number of landfills . The Prima Deshecha landfill is located in San
Juan Capistrano and is owned and operated by OC Waste and Recycling. The facility has a permitted
capacity of 4,000 tons/day and has a closure date of December 2067.01inda Alpha Landfill is owned and
operated by OC Waste and Recycling and is permitted to handle 8,000 tons/day of refuse. This landfill is
projected to close in 2021. The Frank R. Bowerman landfill, located in Irvine, is owned and operated by
OC Waste and Recycling and has a permitted maximum of 11,500 tons/day. The Frank R. Bowerman
landfill is currently slated for closure in December 2053. Additionally, other landfills are available to serve
the City. Compliance with City and County waste reduction programs and policies would reduce the
volume of solid waste entering landfills. Individual development projects within the City would be required
to comply with applicable state and local regulations, thus reducing the amount of landfill waste by at
least 50 percent. Future housing would increase the volume of solid waste generated in the City that is
diverted to existing landfills, thus contributing to the acceleration of landfill closures or the use of more
distant sites. However, the closure dates for the various landfills range from 2021 to 2067. Combined
remaining capacities at the landfills would be adequate to accommodate future housing. Furthermore, no
revisions associated with the General Plan Amendments would affect the development assumptions and
related impact conclusions as determined by the General Plan EIR. Impacts related to sufficient landfill
capacity are anticipated to be less than significant.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not result in insufficient landfill capacity beyond the previously approved 2014-2021 Housing
Element. According to the previously approved 2014-2021 Housing Element Initial Study, individual
development projects within the City would be required to comply with applicable state and local
regulations, thus reducing the amount of landfill waste by at least 50 percent. Future housing would
increase the volume of solid waste generated in the City that is diverted to existing landfills, thus
contributing to the acceleration of landfill closures or the use of more distant sites. However, the closure
dates for the various landfills range from 2021 to 2067. Combined remaining capacities at the landfills

would be adequate to accommodate future housing. Furthermore, no revisions associated with the
General Plan Amendment would affect the development assumptions and related impact conclusions as
determined by the General Plan EIR. Impacts related to insufficient landfill capacity will be consistent with
the previously approved 2014-2021 Housing Element Initial Study and no new impacts will occur . .
g) Comply with federal, state, and local statutes and regulations related to solid waste? No Impact.
Previously Approved 2014-2021 Housing Element Initial Study Conclusion: Residential waste collection in
San Juan Capistrano is disposed of in regional landfills, as described above. All new residential
development will be required to comply with state mandates and City regulations regarding
reduction/recycling of household waste. None of the proposed housing strategies inherent in the
proposed Housing Element or information provided in the other General Plan Amendments would have
any effect upon or result in any conflicts with solid waste disposal regulations, as the scope of these
revisions does not increase development capacity over what was previously analyzed in the General Plan
EIR. No impact will occur.
2014-2021 Housing Element Initial Study Addendum Conclusion: The Amended 2014-2021 Housing
Element will not conflict with federal, state, and local statutes and regulations related to solid waste

Conclusion: The General Plan Conservation & Open Space, Land Use, Community Design, and
Floodplain Management Elements includes long-term environmental goals to protect natural resources
with in the City. Goals include the preservation and enhancement of open space and natural features and
protection of water quality in local creeks and floodplains . The proposed Housing Element identifies
opportunities to accommodate anticipated housing needs w ithin the City over the long-term. As discussed
throughout this Initial Study and particularly in Sections 16 .9, 16.1 0 , 16.14, and 16.15, the Housing
Element will not result in significant environmental impacts related to water quality, park or recreational
facilities, or conflicts with the environmental goals and policies of the General Plan. As an element of the
General Plan, the project defines the long-term housing goals of the City and has no immediate , short-
term goals that would compromise the long-term environmental goals of the General Plan . The City
hereby finds that the project will not ach ieve shot-term goals to the disadvantage of long-term
environmental goals.
2014-2021 Housing Element Initial Study Addendum Conclusion: As mentioned in the previously
approved 2014-2021 Housing Element Initial Study, the General Plan Conservation & Open Space, Land
Use , Community Design, and Floodplain Management Elements includes long-term environmental goals
to protect natural resources within the City . Goals include the preservation and enhancement of open
space and natural features and protection of water quality in local creeks and floodpla ins . The2014-2021
Hous ing Element Addendum identifies opportunities to accommodate anticipated housing needs within
the City over the long-term. As discussed throughout this Initial Study and particularly in Sections 16.9,
16.1 0 , 16.14 , and 16.15, the Housing Element will not result in significant environmental impacts related
to water quality, park or recreational fac ilities , or conflicts with the environmental goals and policies of the
General Plan. As an element of the General Plan, the project defines the long-term housing goals of the
City and has no immediate, short-term goals that would compromise the long-term environmental goals of
the General Plan . The City hereby finds that the project will not achieve shot-term goals to the
disadvantage of long-term environmental goals . Impacts w ill be consistent with the previously approved
2014-2021 Housing Element Initial Study and no new impacts will occur
c) Does the project have impacts which are individually limited , but cumulatively considerable
("Cumulatively considerable" means the project's incremental effects are considerable when compared to
the past, present and future effects of other projects)? Less than Significant Impact with Mitigation
Incorporated. Previously Approved 2014-2021 Housing Element Initial Study Conclusion: Cumulative
impacts can result from the interactions of environmental changes resulting from one proposed project
with changes resulting from other past, present, and future projects that affect the same resources,
utilities and infrastructure systems, public services, transportation network elements, air basin, watershed,
or other physical conditions . Such impacts could be short term and temporary, usually consisting of
overlapping construction impacts , as well as long term, due to the permanent land use changes involved
in the project.
As discussed throughout the Initial Study, there are potential project-level impacts that have been
identified. Potential project-level impacts and proposed mitigation measures are presented in the Cultural
Resources (Section 16.5) section of this Initial Study. Refer the identified section for further discussion of
the specific mitigation measures established to address any identified potential project level impacts.
Cumulative impacts on greenhouse gases, an inherently cumulative issue , are discussed in Section 16.7.
Cumulative effects resulting from full implementation of the City's land use policies were evaluated in the
General Plan EIR. The proposed General Plan Amendments would not change any of these policies and
do not propose any specific development or redevelopment project that could contribute to short-term or
long-term cumulative impacts that were not addressed sufficiently in the General Plan EIR. The proposed
project does not include any changes to land use designations and thus is consistent with the project
analyzed in the General Plan EIR. Overall, the long-term development of the Housing Opportunity sites is
consistent with the growth projections identified in the regional population growth forecast completed by
SCAG . As such, the proposed Housing Element update would not result in new or additional cumulative
Initial Study/Environmental Checklist -110-City of San Juan Ca pistrano, California
impacts. With the implementation of the mitigation measure prescribed at the project-level, the cumulative
impacts would be less than significant. ·
2014-2021 Housing Element Initial Study Addendum Conclusion: According to the previously approved
2014-2021 Housing Element Initial Study, there are potential project-level impacts that have been
identified. Potential project-level impacts and proposed mitigation measures are presented in the Cultural
Resources (Section 16.5) section of this Initial Study. Refer the identified section for further discussion of
the specific mitigation measures established to address any identified potential project level impacts.
Cumulative impacts on greenhouse gases, an inherently cumulative issue, are discussed in Section 16 . 7.
Cumulative effects resulting from full implementation of the City's land use policies were evaluated in the
General Plan EIR. The proposed General Plan Amendment would not change any of these policies and
do not propose any specific development or redevelopment project that could contribute to short-term or
long-term cumulative impacts that were not addressed sufficiently in the General Plan EIR. Overall, the
long-term development of the Amended Housing Opportunity sites is consistent with the growth
projections identified in the regional population growth forecast completed by SCAG. As such, the 2014-
2021 Housing Element Addendum will not result in new or additional cumulative impacts. With the
implementation of the mitigation measure prescribed at the project-level, the cumulative impacts would be
less than significant. Impacts will be consistent with the previously approved 2014-2021 Housing Element
Initial Study and no new impacts will occur.
d) Does the project have environmental effects wh ich will have substantial adverse effects on human
beings. directly or indirectly? Less than Significant Impact. Previously Approved 2014-2021 Housing
Element Initial Study Conclusion : Based on the analysis of the project's impacts in the responses to items
16 .1 thru 16.17, there is no indication that this project could result in substantial adverse effects on
human beings. The analysis concludes that direct and indirect environmental effects will at worst require
mitigation to reduce to less than significant levels. Under each environmental consideration addressed in
the preceding analysis , the proposed project is considered to have little or no adverse impacts on people
and the environment.

Housing Element law allows local governments to utilize "default" density standards determined by HCD. Per HCD's
determination, cities in Orange County (including San Juan Capistrano) with sites allowing a density of at least 30 dwelling units
per acre can be used to meet lower-income RHNA requirements.
•calculations of realistic capacity assume that properties will achieve a density that is 80 percent of the maximum allowed density
with the exception of the Ventanas site (Site 5). For Site 5, realistic capacity calculations use a slightly higher percent (85 percent)
of the maximum allowed density based on recent developer interest in the site. Discussions with potential developers indicate that
realistic capacity for the site is closer to 93 percent of maximum allowed density (in excess of 250 units).
••Affordability of units for the Pacific San Juan site is based on the Planned Community zoning 7.4 acres for a multi-family
development proposing 10.5 dulac and able to accommodate Moderate Income housing based on affordability levels presented in
the General Plan Housing Element.
••• Sites #6-10 were previously included in the 2008 Housing Element.
Site Details
Site 1-The Oaks (APN: 664-041-09/-101-12)
This site is a 10.2 acre on the edge of the City's eastern border and south of Ortega Highway. The current
use on the site is an equestrian stable. A residential development would be a more efficient use of the site
and given the potential units that can be built, may be a financial incentive for the current owners to
redevelop. There is a pending development proposal on this site for 32 units with RS-10,000 zoning.
San Juan Capistrano Housing Element

Site 2-Calle Lorenzo (APN: 649-052-08 & 649-053-13)
This site is a 1.89 acre lot east of Camino Capistrano and south of Junipero Serra Road. It contains the
potential for a total of 12 units in RS-4,000 zoning. The current use on the site is one single family unit.
The site is zoned to permit a larger capacity, and over the last year the site been investigated for
development. No applications for development have been received to date . Given the potential units that
can be built, redevelopment to the sites full potential is expected.
Site 3 -C. Romer Homestead ( APN: 666-241-12)
This site is a 0.35 acre lot east of Rancho Viejo Road and south of Ortega Highway. It contains the
potential for a total of 8 units at densities that can accommodate affordable housing. The site is zoned to
permit a larger capacity, and over the last year the site been investigated for development. No
applications for development have been received to date . Given the potential units that can be built,
redevelopment to the sites full potential is expected.
Site 4-The Groves (APN: 121-050-21)
This 2.0 acre vacant site is located on the northwest corner of Camino Capistrano and Junipero Serra
Road. The site has a potential development capacity for 48 units at densities that can accommodate
affordable housing. Environmental constraints that would have limited development have already been
accounted for in the site analysis . With the required 75 foot set back from the creek as part of the
Resource Agency permitting requirements and the full right-of-way for Camino Capistrano, the site
provides two net useable acres. Only 2 acres are used to calculate realistic capacity.
Site 5-Ventanas (APN: 666-131-09/-13/-15)
This 9 acre vacant site located east of Interstate 5 and north of San Juan Creek, has been identified as a
potential site for housing development due to access to transit, schools, etc. The site additionally has a
potential for mixed use. The site has a potential development capacity for 230 units. The realistic capacity
of 230 units is supported by a recent developer analysis which determined that 253 units could be
accommodated on the site with a mixed use element. For the purposes of this site inventory, capacity for
the Ventanas site is based solely on the portion of the site allowing Very High Density residential and
does n9t include portions of the site allowing commercial development.
Sites 6-10
Opportunities for moderate or above moderate income housing are available on sites #6 -#1 0. These five
sites were previously included in the 2008 Housing Element, have appropriate zoning in place and have
not been developed. Site #6, Oliva, has the potential for 40 low-density units on 3.5 acres. Site #7, The
Cove Estates (referred to as Village Alipaz in the 2008 Housing Element), has the capacity for 4 units in
1.8 acres zoned RS-4,000. Affordability of units for the Pacific San Juan site (Site #8) is based on the
Planned Community zoning 7.4 acres for a multi-family development proposing 10 .5 dulac and able to
accommodate moderate income housing based on affordability levels presented in the Housing Element.
Site # 9, the Don Juan Duplexes property, is located at the terminus of Andres Pica west of Interstate 5.
The site has the potential development of 8 units on a total of 2.1 acres in MRD-4000 zoning. Site # 10,
Hidden Creek Estates, is located west of Camino Capistrano and has the potential for the development of
8 units on a total of 3.0 acres in RS-10,000 zoning.
Site 11: City Hall (APN: 668-101-10)
Site 11 is zoned for high density residential development and currently houses City Hall and a Public
Works & Utility Department equipment storage building. The site has a capacity for 61 units at densities
appropriate to accommodate lower-income housing. The site is owned by the City of San Juan

Capistrano and its current uses are not an impediment to development of the site . City Hall offices would
be relocated in the event that a development project was approved on the site.

The City has required, and will continue to require, all new residential developments to provide a
minimum of ten percent of its units as affordable through its implementation ordinances. If a residential
developer does not provide the units within the boundary, they may participate in the construction of
affordable housing in another location in the City or be subject to payment of the Housing In -lieu fee
which is calculated using the housing market variables. The rental developments have a fee that is
calculated annually, and ownership developments have a fee that is calculated monthly. The fee formula
is within the City of San Juan Capistrano Municipal Code Section 9-5.103 . The Housing In-lieu Fee is
used to assist in the creation of affordable housing opportunities.
Housing Choice Voucher
The Orange County Housing Authority administers the Housing Choice Voucher Program (formerly the
Section 8 Rental Assistance Program) that extends rental subsidies to very low-income households . The
subsidy represents the difference between the excess of 30 percent of the recipient's monthly income and
the federally approved fair market rents. As of October 2013 , the Orange County Housing Authority was
assisting 68 households through the Housing Choice Voucher Program.
Department of Housing and Urban Development Grants
The City receives CDBG/HOME funds through the competitive state HUD program as San Juan
Capistrano is not an entitlement jurisdiction. Since 2008 , the City has received $1,379,942 through State
Grants and reimbursements from loans for the Owner Occupied Rehabilitation Program . This averages
$275,988 received annually for the Owner Occupied Rehabilitation Program . This program offers $20,000
to $30,000 loans for Lower income households to correct code violations, Health and Safety concerns,
weatherization improvements and accessibility improvements.
