A MITIGATED NEGATIVE DECLARATION
From: Development Services Department
32400 Paseo Adelanto
San Juan Capistrano, California 92675
Church of Jesus Christ of Latter Day Saints Meetinghouse Project; an application
to develop a 16,558-square-foot meetinghouse/cultural hall building and chapel
located on the north side of Stallion Ridge (formerly Vista Montana), northwest of
the Avenida La Pata and Stallion Ridge intersection in San Juan Capistrano,
California (Assessor's Parcel Number 664-251-31).
NOTICE IS HEREBY GIVEN that the City of San Juan Capistrano has prepared and intends to
adopt a Mitigated Negative Declaration (MND) in connection with the Proposed Project. The
MND identifies potential effects with respect to environmental resources . The MND also
includes proposed mitigation measures that will ensure that the Proposed Project would not
result in any significant, adverse effects on the environment. The City's decision to prepare a
MND should not be construed as a recommendation of either approval or denial of this
Proposed Project.
The Initial Study which serves as the substantial evidence and as a basis for the MND, is
available for public review and can be found on the City's website at:
http://sanjuancaptstrano.org/DepartmentstDevelopmentServices/P ianninqZoning/Environmental
-Documents and is available in the Development Services Department at City Hall located at
32400 Paseo Adelanto, San Juan Capistrano, CA 92675 .
PROJECT DESCRIPTION: The Proposed Project site consists of an approximately 4.54-acre
property that is generally located on the north side of Stallion Ridge (formerly Vista Montana),
northwest of the Avenida La Pata and Stallion Ridge intersection in the City. The Proposed
Project entails development of a 16,558-square-foot Meetinghouse/Cultural Hall building and
chapel with 292 fixed seats and pews on the 4.54-acre site. The maximum occupancy of the
proposed Meetinghouse/Cultural Hall building and chapel is estimated to be 1,151 persons. The
building includes a multi-purpose room which is intended to be used for basketball, volleyball,
and dining purposes. The remainder of the proposed Meetinghouse/Cultural Hall building
consists of offices, classrooms, and support uses. The Project also includes a storage shed, an
outdoor 1 ,990-square-foot pavilion, and a trash enclosure. The proposed parking area would
include 229 parking spaces and access to the Project site would be provided from Stallion
Ridge (formerly Vista Montana) and from the San Juan Hills High School private access road.
Because the Whispering Hills Estates Planned Community Comprehensive Development Plan
(COP 04-01) envisioned single family residential uses on the Project site, an amendment to
CDP 04-01 would be required for the Proposed Project.

Lead Agency: City of San Juan Capistrano
Development Services Department
32400 Paseo Adelanto
San Juan Capistrano, CA 926 75
Project Title: Church of Jesus Christ of Latter Day Saints Meetinghouse
Project Location: The project site is located on the north side of Stallion Ridge (formerly Vista Montana), northwest
of the Avenida La Pata and Stallion Ridge intersection in San Juan Capistrano, California. The project site totals
approximately 4.54 acres and is currently undeveloped. While the project site is undeveloped, the site has been
mass graded in conjunction with the overall grading associated with the adjacent high school and the Whispering
Hills Estate subdivision. The Assessor's Parcel Number (APN) for the project site is 664-251-31.
Project Description: The project includes development of a 16,558-square-foot Meetinghouse/Cultural Hall
building and chapel with 292 fixed seats and pews on the 4.54-acre site. The maximum occupancy of the proposed
Meetinghouse/Cultural Hall building and chapel is estimated to be 1,151 persons. The building includes a multi-
purpose room which is intended to be used for basketball, volleyball, and dining purposes. The remainder of the
proposed Meetinghouse/Cultural Hall building consists of offices, classrooms, and support uses. The project also
includes a storage shed, an outdoor 1,990-square-foot pavilion, and a trash enclosure. The proposed parking area
would include 229 parking spaces. Access to the project site would be provided from Stallion Ridge (formerly Vista
Montana) and from the San Juan Hills High School private access road.
The proposed church building has a "Tuscan Revival" architectural style. This architectural style is one of the
recommended styles in the City of San Juan Capistrano's Architectural Design Guidelines. The church building has a
roof height of 3 7-feet, 8-inches. The church building and the pavilion will include concrete Mission roof tile and will
be painted with earth-tone colors; and include cultured stone. Landscaping is proposed throughout the site and
along the perimeter of the church building and the pavilion.
Because the Whispering Hills Estates Planned Community Comprehensive Development Plan (COP 04-01)
envisioned single family residential uses on the project site, an amendment to COP 04-01 would be required for the
proposed project. This code amendment would allow the proposed church use with a Conditional Use Permit. The
church use would then be reviewed based on the amended COP 04-01.
The proposed project would connect to existing City infrastructure to provide water, sewer, and storm drainage
utilities. A water quality basin would be located in the northern portion of the project site. Police protection service
would be provided by the Orange County Sheriff's Department (OCSD). The Orange County Fire Authority (OCFA)
would provide fire protection service. School services would be provided by the Capistrano Unified School District
(CUSD). Electricity will be provided by San Diego Gas & Electric and natural gas will be provided by The Gas
Company.
Findings:
In accordance with the California Environmental Quality Act, the City of San Juan Capistrano has prepared an Initial
Study to determine whether the proposed project may have a significant adverse effect on the environment. The
Initial Study and Proposed Mitigated Negative Declaration reflect the independent judgment of City of San Juan
Capistrano staff. On the basis of the Initial Study, the City of San Juan Capistrano hereby finds:
Although the proposed project could have a significant adverse effect on the environment, there will not be a
significant adverse effect in this case because the project has incorporated specific provisions to reduce
impacts to a less than significant level and/or the mitigation measures described herein have been added to
the project. A Mitigated Negative Declaration has thus been prepared.
The Initial Study, which provides the basis and reasons for this determination, is attached and/or referenced herein
and is hereby made a part of this document.
Signature Date
Proposed Mitigation Measures:
The following Mitigation Measures are extracted from the Initial Study. These measures are designed to avoid or
minimize potentially significant impacts, and thereby reduce them to an insignificant level. A Mitigation Monitoring
and Reporting Program (MMRP) is an integral part of project implementation to ensure that mitigation is properly
implemented by the City of San Juan Capistrano and the implementing agencies. The MMRP will describe actions
required to implement the appropriate mitigation for each CEQA category including identifying the responsible
agency, program timing, and program monitoring requirements. Based on the analysis and conclusions of the Initial
Study, the impacts of proposed project would be mitigated to less-than-significant levels with the implementation of
the mitigation measures presented below.
BIOLOGICAL RESOURCES
Mitigation Measure Bio-1: Prior to any permit issuance for grubbing, grading, tree trimming/removal or prior to
engaging in such activities that would occur between the breeding season for native birds [February 15 through july
31 ), the project applicant shall retain the services of a qualified ornithologist to conduct an ornithological survey of the
construction zone. The City will require the developer to submit a copy of the executed contract for such services prior
to the issuance of any grading permits. The ornithological survey shall occur not more than seven days prior to the
initiation of those grading/construction activities. If the ornithologist detects any occupied nests of native birds within
the construction zone or in close proximity to, they shall be mapped on construction plans and the project applicant will
fence off the area[s) supporting bird nests with temporary construction fencing, providing a minimum buffer of 200 feet
between the nest and limits of construction. {This buffer zone shall be at least 500 feet for rap tors until the young have
fledged, are no longer being fed by the parents, have left the nest, and will no longer be impacted by the project) The
construction crew will be instructed to avoid any activities in the zone until the bird nest(s) isjare no longer occupied,
per a subsequent survey by the qualified ornithologist Alternatively, the project applicant will consult as appropriate
with the USFWS to discuss the potentia/loss of nests of native birds covered by the MBTA to obtain the appropriate
permit from the USFWS.
CULTURAL RESOURCES
Mitigation Measure Cul-1: A qualified archaeologist [defined as an archaeologist on the List of Certified
Archaeologists for Orange County) shall be retained by the project applicant and shall be present at pre-construction
meetings to advise construction contractors about the sensitive nature of cultural resources located on andjor in the
vicinity of the project site, as well as monitoring requirements. A qualified monitor (defined as an individual with a
bachelors degree in anthropology with archaeological monitoring experience), supervised by the qualified
archaeologist, shall observe on-and off-site construction activities that result in grading, andjor excavating on or
below the original ground surface (including during project-related off-site utility [natural gas, electricity, sewer, water,
drainage, communications, etc.] and roadway improvements). Should nonhuman cultural resources be discovered, the
monitor shall have the power to temporarily halt or divert construction activities until the qualified archaeologist can
determine if the resources are significant and, if significant, until recovered by the archaeologist. In the event that
human remains are discovered, construction activities shall be halted or diverted until the provisions of §7050.5 of the
Health and Safety Code and §5097.98 of the Public Resources Code have been implemented.
Mitigation Measure Cul-2: During construction/grading activities, a Native American monitor shall observe
construction/grading activities that result in grading, excavating, andjor trenching on or below the original ground
surface (including during project-related offsite utility [e.g., natural gas, electricity, sewer, water, drainage,
communications, etc.] and roadway improvements). The Native American monitor shall consult with the archaeological
monitor regarding objects and remains encountered during grading that may be considered sacred or important. In the
event that evidence of human remains is discovered, the Native American monitor shall verifY that the archaeologist
has notified the Coroner.
Mitigation Measure Cul-3: If a significant Tribal Cultural Resource andjor unique archaeological resource is
inadvertently discovered during ground disturbing activities for this the project, the juanefio Band of Mission Indians
Acjachemen Nation UBMIAN) respectfully request Pursuant to California Public Resources Code Section 21083.2 [b)
avoidance is the preferred method of preservation for archaeological, historical, paleontological and Tribal Cultural
Resources., If however, it is demonstrated that avoidance of a significant andjor unique cultural resource is infeasible, a
data recovery plan shall be prepared and submitted to the City ofSanjuan Capistrano and the ]BMIAN.
Mitigation Measure Cul-4: If any prehistoric or historic artifacts, human remains or other indications of
archaeological or paleontological resources are found during grading and construction activities, an archaeologist
meeting the Secretary of the Interior's Professional Qualifications Standards in prehistoric or historical archaeology, as
appropriate, shall be consulted to evaluate the finds and recommend appropriate mitigation measures.
• If cultural resources are identified, every effort shall be made to avoid the resources, with preservation an
important goal. If significant sites cannot feasibly be avoided, appropriate measures, such as data recovery
excavations or photographic documentation of buildings, shall be undertaken consistent with applicable state
and federal regulations. If the find is determined to be be a tribal cultural resource and the discovered
archaeological resource cannot be avoided, then applicable mitigation measures for the resource shall be
discussed with the geographically affiliated tribe. Applicable mitigation measures that also take into account
the cultural values and meaning of the discovered tribal cultural resource, including confidentiality if
requested by the tribe, shall be completed {e.g., preservation in place, data recovery program pursuant to PRC
§21083.2[i]). During evaluation or mitigative treatment, ground disturbance and construction work could
continue on other parts of the project site.
• If human remains are discovered, all work shall be halted immediately within 50 meters {165 feet) of the
discovery, the County Coroner must be notified, according to Section 5097.98 of the State Public Resources
Code and Section 7050.5 of California's Health and Safety Code. If the remains are determined to be Native
American, the coroner will notify the Native American Heritage Commission, and the procedures outlined in
CEQA Section 15064.5{d) and {e) shall be followed.
• If any fossils are encountered, there shall be no further disturbance of the area surrounding this find until the
materials have been evaluated by a qualified paleontologist, and appropriate treatment measures have been
identified.
GEOLOGY AND SOILS
Mitigation Measure Geo-1: Prior to earthmoving activities for the project, a certified geotechnical engineer, or
equivalent, shall be retained to perform a final geotechnical evaluation of the soils at a design -level as required by the
requirements of the California Building Code Title 24, Part 2, Chapter 18, Section 1803.1.1.2 related to expansive soils
and other soil conditions. The evaluation shall be prepared in accordance with the standards and requirements outlined
in California Building Code, Title 24, Part 2, Chapter 16, Chapter 17, and Chapter 18, which addresses structural design,
tests and inspections, and soils and foundation standards. The final geotechnical evaluation shall include design
recommendations to ensure that soil conditions do not pose a threat to the health and safety of people or structures,
including threats from landslides, unstable soils, expansive soils, or post-construction settlement. The grading and
improvement plans shall be designed in accordance with the recommendations provided in the final geotechnical
evaluation.
Mitigation Measure Geo-2: The project applicant shall submit a Notice of Intent {NO/) and Storm Water Pollution
Prevention Plan {SWPPP) to the RWQCB in accordance with the NPDES General Construction Permit requirements. The
SWPPP shall be designed to control pollutant discharges utilizing Best Management Practices {BMPs) and technology
to reduce erosion and sediments. BMPs may consist of a wide variety of measures taken to reduce pollutants in
stormwater runoff from the project site. Measures shall include temporary erosion control measures {such as silt fences,
staked straw bales/wattles, silt/sediment basins and traps, check dams, geofabric, sandbag dikes, and temporary
revegetation or other ground cover) that will be employed to control erosion from disturbed areas. Final selection of
BMPs will be subject to approval by the City of San juan Capistrano and the RWQCB. The SWPPP will be kept on site
during construction activity and will be made available upon request to representatives of the RWQCB and City.
HYDROLOGY AND WATER QUALITY
Mitigation Measure Hydro-1: The storm drainage plan shall be designed and engineered to ensure that post-project
runoff is equal to or less than pre-project runoff The applicant shall provide the City Engineer with all storm water
runoff calculations with the improvement plan submittal.

CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
PROJECT DESCRIPTION
The proposed project includes development of a 16,558-square-foot Meetinghouse/Cultural
Hall building and chapel with 292 fixed seats and pews on the 4.54-acre site. The maximum
occupancy of the proposed Meetinghouse/Cultural Hall building and chapel is estimated to be
1,151 persons. The building includes a multi-purpose room which is intended t o b e use d fo r
basketball, volleyball, and dining purposes. The remainder of the proposed
Meetinghouse/Cultural Hall building consists of offices, classrooms, and support uses. The
project also includes a storage shed, an outdoor 1,990-square-foot pavilion, and a trash
enclosure. The proposed pavilion would be used for congregational picnics with under 75
adults and children, and smaller youth gatherings such as Cub Scout Troop activities, or other
similar teen discussions. The aforementioned congregational picnics and other youth activities
would occur on a few occasions during the year, usually on Tuesday or Wednesday evenings.
Events for elementary school aged children would occur between 4:00 PM and 6:30 PM, and
events for youth and/or adults would occur between 7:00 PM and 8:30 PM. The outdoor
pavilion area is not anticipated to host concerts or other similar events which would attract
large crowds or would require amplified music. The congregation activities with 75 or fewer
attendees would occur once or twice a year on a Saturday afternoon.
The proposed parking area would include 229 parking spaces. Access to the project site would
be provided from Stallion Ridge (formerly Vista Montana) and from the San Juan Hills High
School private access road.
The proposed church building has a "Tuscan Revival" architectural style. This architectural style
is one of the recommended styles in the City of San Juan Capistrano's Architectural Design
Guidelines. The church building has a roof height of 37 -feet, 8-inches. The church building and
the pavilion will include concrete Mission roof tile and will be painted with earth-tone colors;
and include cultured stone. Landscaping is proposed throughout the site and along the
perimeter of the church building and the pavilion.
Because the Whispering Hills Estates Planned Community Comprehensive Development Plan
(COP 04-01) envisioned single family residential uses on the project site, an amendment to COP
04-01 would be required for the proposed project. This code amendment would allow the
proposed church use with a Conditional Use Permit. The church use would then be reviewed
based on the amended COP 04-01.
The proposed project would connect to existing City infrastructure to provide water, sewer, and
storm drainage utilities. A water quality basin would be located in the northern portion of the
project site. Police protection service would be provided by the Orange County Sheriffs
Department (OCSD). The Orange County Fire Authority (OCFA) would provide fire protection
service. School services would be provided by the Capistrano Unified School District (CUSD).
Electricity will be provided by San Diego Gas & Electric and natural gas will be provided by The
Gas Company.
The project plans, including architectural renderings, occupancy plan, site plan, main floor plan,
elevations, architectural details, conceptual grading plan, storm drain plan, conceptual utility
plan, preliminary planting plan, and preliminary irrigation plan, are included in Appendix A.
REQUESTED ENTITLEMENTS AND OTHER APPROVALS
The City of San Juan Capistrano is the Lead Agency for the proposed project, pursuant to the
State Guidelines for Implementation of CEQA, Section 15050.

Mandatory Findings of
Significance
DETERMINATION
On the basis of this initial evaluation:
I find that the proposed project COULD NOT have a significant effect on the environment, and a
NEGATIVE DECLARATION will be prepared.
I find that although the proposed proj e ct could have a significant effect on the environment, there
X will not be a significant effect in this case because revisions in the project have been made by or
agre ed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared.
I find that th e proposed project MAY have a significant effect on th e environment, and an
ENVIRONMENTAL IMPACT REPORT is required.
I find that the proposed project MAY h a ve a "potentially significant impact" or "potentially
significant unless mitigated" impact on the environment, but at least one effect 1) has bee n
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 described 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.

EVALUATION INSTRUCTIONS
1) A brief explanation is required for all answers except "No Impact" answ e r s that a r e
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 lead agency 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 Section XVII, "Earlier Analyses," 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) Lead agencies are encouraged to incorporate into the checklist references to
information sources for potential impacts (e.g., general plans, zoning ordinances).
L PAGH20
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
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) Supporting Information Sources: A source list should be attached, and other sources
used or individuals contacted should be cited in the discussion.
8) This is only a suggested form, and lead agencies are free to use different formats;
however, lead agencies should normally address the questions from this checklist that
are relevant to a project's environmental effects in whatever format is selected.
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
significant.
EVALUATION OF ENVIRONMENTAL IMPACTS
In each area of potential impact listed in this section, there are one or more questions which
assess the degree of potential environmental effect. A response is provided to each question
using one of the four impact evaluation criteria described below. A discussion of the response is
also included.
• Potentially Significant Impact. This response is appropriate when there is substantial
evidence that an effect is significant. If there are one or more "Potentially Significant
Impact" entries, upon completion of the Initial Study, an EIR is required.
• Less than Significant With Mitigation Incorporated. This response applies when 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.
• Less than Significant Impact. A less than significant impact is one which is deemed to
have little or no adverse effect on the environment. Mitigation measures are, therefore,
not necessary, although they may be recommended to further reduce a minor impact.
• No Impact. These issues were either identified as having no impact on the environment,
or they are not relevant to the Project.

Responses to Checklist Questions
Responses a), c): The City of San Juan Capistrano adopted Architectural Design Guidelines in
1991. The design guidelines are intended to implement the General Plan goals and policies in
order to promote high quality development for the preservation and enhancement of the
character of the City. The City uses the Design Guidelines during the development review
process to ensure that the " ... highest level of design quality and creativity" are achieved in each
project proposed in San Juan Capistrano . The Design Guidelines supplement the San Juan
Capistrano Municipal Code (Zoning) to ensure that the City's urban design goals are achieved.
A scenic vista is generally considered to be a location from which the public can experience
unique and exemplary high-quality views-often from elevated vantage points that offer
panoramic views of great breadth and depth. Examples would be views from mountain ranges,
valleys, ridgelin e s, or water bodies, although other viewpoints with exceptionally high visual
quality may be defined as a scenic vista. The City has not designated any area within the city
limits as a scenic vista, however, the City's Community Design Element of the General Plan
identifies major travelways, including both vehicular and rail, as " ... providing the public with a
visual image of the quality of life envisioned by the community." As indicated in the Community
Design Element, scenic corridors include designated arterials contained in the Circulation
Element and the railroad corridor that passes through the City. In the vicinity of the project site,
only La Pata Avenue is designated as a scenic corridor.
Three visual simulations were prepared from public vantage points to evaluate the potential
visual and aesthetic impacts anticipated to result from the implementation of the proposed
project. The vantage points were selected because they represent locations from which
important public views to the site exist, including view corridors along arterial roadways and
PAGE22
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT INITIAL STUDY
locations having public access. Vantage points are selected to be representative of a general
area/location, but it is not intended to represent every conceivable visual vantage point of the
project. The selected view simulations, taken in their entirety, provide a representative
overview of the potential view impacts that can be anticipated by the project. Table 1 identifies
and describes the locations from which the photographs were taken and visual simulations
created. Each of the three view locations and the respective view orientation are illustrated in
Figures 7, 8, and 9.
Table 1: Key View Points for Visual Simulations
View# (Figure) View Location View Orientation
1 (Figure 7) Stallion Ridge (Vista Montana) Northeast
2 (Figure 8) Via Granada I Stallion Ridge (Vista Montana) intersection Northwest
3 [Figure 9) Stallion Ridge (Vista Montana) Northwest
SOURCE: MAXEY GROUP -INTERNATIONAL URBAN DESIGN CONSULTANCY.
For analysis purposes, a scenic vista can be discussed in terms of a foreground, middle ground,
and background viewshed. The middle ground and background viewshed is often referred to as
the broad viewshed. Scenic vistas include a focal point of the forefront of the broad viewshed,
such as visually important trees, rocks, or historic buildings. An impact would generally occur if
a project would change the view to the middle ground or background elements of the broad
viewshed, or remove the visually important trees, rocks, or historic buildings in the foreground.
Figure 7 shows views of the project site from the south of the project site, looking northeast
down Stallion Ridge into the project site. The two images shown in Figure 7 depict the existing
site conditions, as well as a photo simulation of post-development site conditions. Figure 8
shows views of the project site from the intersection of Via Granada and Stallion Ridge, looking
northwest down Stallion Ridge into the project site. The two images shown in Figure 8 depict
the existing site conditions, as well as a photo simulation of post-development site conditions.
Figure 9 shows views of the project site from the south of the project site, looking northwest
down Stallion Ridge into the project site. The two images shown in Figure 9 depict the existing
site conditions, as well as a photo simulation of post-development site conditions.
As illustrated in the visual simulations, development of the project site would introduce a public
church structure onto a site that is currently undeveloped and visually perceived as open space.
Although surrounded by existing urban development, such as roads, a school, and residential
uses, development of the proposed project would convert a currently vacant parcel into
developed uses. As shown in the visual simulations, the proposed project will not significantly
disrupt middle ground or background views from public viewpoints. The proposed project
would result in changes to the foreground views from the public viewpoint by adding a church
structure to a site that is undeveloped.
Although the visual character of the project site would be significantly altered as a result of
project implementation, the guidelines and standards within the Whispering Hills Estate
Planned Community would ensure consistent development that is in line with the City's vision
for the area. The design features of the proposed project are meant to be consistent with, and
complimentary to, the surrounding existing development. Views of the project site would be
visually filtered from the roadway with proposed landscaping. The intent of the landscaping is
to help subordinate the urbanized image of development through screening, which would
lessen the scale and presence of the development to the extent feasible.
PAG623
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
Given the topography of the project site and the elevated roadway to the east, views of the
project site are limited from surrounding lands. Views are most prominent from the adjacent
Stallion Ridge roadway. Figures 7 through 9 shows that while development of the site would be
highly visible to motorists travelling on adjacent roadways, the visual character of the project
site would be consistent with the goals established by the General Plan and City Development
Code, and would be compatible and complimentary to existing development in the vicinity of
the site.
Conclusion
Upon build-out, the project would be of similar visual character to adjacent existing and future
developments. For motorists travelling along nearby roadways, such as Stallion Ridge or La
Pata Avenue, the project would appear to be a continuation of adjacent land uses and would not
present unexpected or otherwise unpleasant aesthetic values within the general project
vicinity. The greatest visual change would apply to neighbors that abut the project site with a
direct view of the area. Generally, views of the project site are not visible from many nearby
residences du e to th e existing buildings, fencing/walls, mature trees, and vegetation that
obscure views. Most neighbors would see the visual change while traveling along the public
roadways that front the project site. The change in character of the project site, once developed,
is anticipated by the General Plan and would be visually compatible with surrounding existing
residential neighborhoods to the north, south, east, and west. Implementation of the design
guidelines and standards in the Comprehensive Development Plan would ensure that impacts
to visual resources would be minimized to the extent feasible. The project would not
substantially degrade a scenic vista, or the existing visual character/quality of the site and its
surroundings, and this impact would be less than significant.
Response b): The project site is not located within view of a state scenic highway. The nearest
highway subject to this program is State Route (SR) 74, an Eligible Designated State Scenic
Highways, located approximately 1.2 miles north of the project site. Trees, rock outcroppings,
and historic buildings are not located on the project site. The proposed project would not
substantially damage scenic resources, including, but not limited to, trees, rock outcroppings,
and historic buildings within a state scenic highway. Implementation of the proposed project
would have no impact relative to this topic.
Response d): Existing development and streets to the north, south, east, and west currently
produce a moderate amount of nighttime lighting from street lighting, residential interiors, and
exterior building lighting. The school facility also provides facility lighting for parking,
buildings, and stadium lighting.
The project site is currently undeveloped and does not contain existing lighting or glare. Light
sources from the proposed project would be consistent with the type and intensity of existing
parking and building lighting sources at the adjacent school facility. When viewed from more
distant areas, the lighting associated with the proposed development would slightly increase
because the existing project site is currently dark. The use of specific building materials
approved through the design review process would ensure that there are not extensive
reflective building materials that would cause glare.
The General Plan Community Design Element addresses exterior lighting. As suggested in that
element, exterior lighting levels should be the minimum necessary to protect the public safety.
Specifically, lighting in the community must be designed to achieve the following criteria:
L PAGE24
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT JNmALSnJDY
• Within residential neighborhoods in hillside areas, street lights should be minimized
and located at street intersections, curves in streets and at the end of cui-de-sacs.
• Within non-residential areas, both pedestrian and parking lot lighting should be set at
minimum levels recommended by the illuminating Engineering Society for public safety.
• Recreation lighting should require special studies and analysis to minimize light
intrusion into adjacent neighborhoods.
The Whispering Hills Estates CDP does not include lighting standards; however, the proposed
project will be required to comply with the City's existing regulations and conditions to ensure
that potential light and glare is minimized within the area. These include: compliance with the
City's Architectural Design Guidelines and the Whispering Hills Estates CDP through the City's
design review process; compliance with Section 9-3.529 of the Municipal Code, which pertains
to street, signage, landscape, and parking lot lighting sources; and compliance with Section 9.3-
529 of the Municipal Code, which pertains to lighting and photometric plan(s).
The lighting proposed for the project should complement the architectural style of the buildings
and retain a pedestrian scale while providing illumination of the building facade and entrances
and to enhance the desired atmosphere of the Whispering Hills Estates Planned Community. To
achieve those goals, the project would be required to include the following :
• Parking areas shall have lighting capable of providing adequate illumination for security
and safety. Lighting standards shall be energy-efficient and in scale with the height and
use of the on-site structures.
• All illumination, including security lighting, shall be directed downward, away from
adjacent properties and public rights-of-way preventing spillover onto adjoining
properties, streets, or skyward.
• Lighting systems should be designed for normal levels during operating hours and
reduced intensity levels throughout late, non-operational hours (for security purposes.
• Any new street lighting shall match the existing fixtures within the Whispering Hills
Planned Community.
Although lighting for the exterior parking and related exterior lighting will provide for
maximum permitted illumination within the project site for parking areas and walkways,
buildings, signage, etc., the proposed lighting must comply with Section 9.3-529 of the City's
Municipal Code. Lighting for the project must also be designed to meet the objectives in the
Community Design Element, including the preparation of a photometric plan, which will be
prepared and submitted to the City that demonstrates to the satisfaction of the Development
Services Director or a designee that illumination does not create off-site light and glare. As a
result, the introduction of exterior lighting would comply with the City's lighting requirements
and would not result in potentially significant adverse impacts. Therefore, impacts associated
with the creation of light or glare, such that it adversely affects daytime or nighttime views in
the area, would be less than significant.

Responses a-c): Air quality emissions would be generated during construction of the proposed
project and during operation of the proposed project. Construction-related air quality impacts
and operational air quality impacts are addressed separately below.
Construction-Related Emissions
Cons t ru ction Activit ie s /Sche dule : Construction activities will consist of multiple activities over
several months. These construction activities can be described as site improvements (grading,
underground infrastructure, and topside improvements) and vertical construction (building
construction and architectural coatings). For purposes of this analysis, it is assumed that the
entire project is built-out from October 2017 to November 2018. The assumptions made for the
air quality and greenhouse gas emissions analysis are included as Appendix B.
Site Improvements : For purposes of this analysis it is assumed that site improvements are
installed in one phase. The site improvement phase of construction will begin with site
preparation. Site preparation will include the use of scrapers and loaders to strip (clear and
grub) all organic materials and the upper half-inch to inch of soil from the project site. This task
will generally take approximately five days to complete and will include vehicle trips from
construction workers.
[ PAGE37 ]
INITIAllSruDY CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROjECT
After the site is stripped of organic materials grading will begin. This activity will involve the
use of excavators, graders, dozers, loaders, and backhoes to move soil around the project site to
create specific engineered grade elevations and soil compaction levels. After grading and
compaction all underground infrastructure would be installed. This includes the excavation of
trenches to install storm water, wastewater, potable water, and dry utilities, and then
backfilling and compacting the soil over the infrastructure. Grading and infrastructure for the
project site would take approximately 14 days and will include vehicle trips from construction
workers. (Note: It would be possible to grade the site under a more compacted schedule with extra
equipment operating or under a longer time frame with less equipment.).
The last task is to install the topside improvements, which includes pouring concrete curbs,
gutters, sidewalks, and access aprons and then paving of all streets and parking lots. This task
will involve the use of pavers, paving equipment, and rollers and will take approximately three
days and will include vehicle trips from construction workers. (Note: It would be possible to
install the topside improvements under a more compacted schedule with extra equipment
operating or under a longer timeframe with less equipment).
Building Construction/Architectural Coatings: Building construction involves the vertical
construction of structures and landscaping around the structures. This task will involve the use
of cranes, forklifts, generator sets, cement and mortar mixers, and small
tractors/loaders/backhoes. For purposes of this analysis it is assumed that the entire project is
constructed in approximately 270 days (12.5 months). Architectural coatings involve the
interior and exterior painting associated with the structures. This task will generally be
completed within five days once the two proposed structures are completed.
Construction Emission s: A quantification of the emissions of nitrogen oxides (NOx), carbon
monoxide (CO), coarse particulate matter (PM1o), and fine particulate matter (PMz .s ) that will be
emitted by project construction has been performed. CalEEMod™ (v. 2016.3.1) was used to
estimate construction emissions for the proposed project. Below is a list of model assumptions
used in the construction screens of CalEEMod. Table 2 presents the estimated construction
phase schedule, which shows the duration of each construction phase. Table 3 shows the off-
road construction equipment used during construction for each phase. Following these tables
are a list of default factors that were used in the model.

The SCAQMD has established construction related emiSSions thresholds of significance as
follows: 100 pounds per day (lbsjday) of NO x, 550 lbsjday of CO, 55 lbs/day of PMz.s, and 150
lbsjday of PMto· If the proposed project's emissions will exceed the SCAQMD's threshold of
significance for construction-generated emissions, the proposed project will have a significant
impact on air quality and all feasible mitigation are required to be implemented to reduce
emissions. As shown in Table 4 above, annual construction emissions of NOx, CO, PM2.s, and
PM to will not exceed the SCAQMD thresholds of significance in any given year.
The project will be subject to SCAQMD Rule 403 (Fugitive Dust) during construction. SCAQMD
Rule 403 does not require a permit for construction activities, but rather, sets forth general and
specific requirements for all construction sites (as well as other fugitive dust sources) in the
SoCAB. The general requirement prohibits a person from causing or allowing emissions of
fugitive dust from construction (or other fugitive dust source) such that the presence of such
PAGR39
INITIAL STuDY CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
dust remains visible in the atmosphere beyond the property line of the emissions source.
SCAQMD Rule 403 also prohibits a construction site from causing an incremental PMto
concentration impact at the property line of more than SO micrograms per cubic meter as
determined through PMto high-volume sampling, but the concentration standard and associated
PM10 sampling do not apply if specific measures identified in the rule are implemented and
appropriately documented. In accordance with Rule 403, the SCAQMD requires that contractors
implement Best Available Control Technology (BACT) for construction activities. Rule 403
identifies two sets of specific measures, one for all projects and another set of conditions for
projects that exceed SO acres. The proposed project will be required to implement Rule 403
during construction activities to ensure particulates are minimized.
Because construction of the proposed project would not exceed SCAQMD's air quality
significance thresholds for construction emissions, the proposed project would have a less than
significant impact related to construction emissions.
Operational Emissions
The SCAQMD is tasked with implementing programs and regulations r equir ed by the Feder al
Clean Air Act and the California Clean Air Act. In that capacity, the SCAQMD has prepared plans
to attain Federal and State ambient air quality standards. To achieve attainment with the
standards, the SCAQMD has established thresholds of significance for criteria pollutant
e m ission s in their SCAQMD Air Qu ality Sign ifica nce Th res hol ds (20 1 5) doc umen t. Pro jects wi th
emissions below the thresholds of significance for criteria pollutants would be determine d to
"Not conflict or obstruct implementation of the District's air quality plan".
The proposed project would be a direct and indirect source of air pollution, in that it would
generate and attract vehicle trips in the region (mobile source emissions) and it would increase
area source emissions and energy consumption. The mobile source emissions would be entirely
from vehicles, while the area source emissions would be primarily from the use of natural gas
fuel combustion, landscape fuel combustion, consumer products, and architectural coatings.
CalEEMod™ (v .2016.3.1) was used to estimate emissions for buildout of the proposed project.
Table S shows the emissions, which include mobile, area source, and energy emissions of
criteria pollutants that would result from operations of the proposed project.

The SCAQMD has established their thresholds of significance by which the project emissions are
compared against to determine the level of significance. The SCAQMD has established
operations related emissions thresholds of significance as follows: 55 lbs/day of NOx, 550
lbsjday of CO, 55 lbsjday of PMz.s, and 150 lbs/day of PM1o. If the proposed project's emissions
will exceed the SCAQMD's threshold of significance for operational-generated emissions, the
proposed project will have a significant impact on air quality and all feasible mitigation are
required to be implemented to reduce emissions to the extent feasible. As shown in Table 5
above, annual emissions of NOx, CO, PMz.s, and PM10 would not exceed the SCAQMD thresholds
of significance. Because the annual emissions of NOx, CO, PMz .s, and PM1o would not exceed the
SCAQMD thresholds of significance, operation of the proposed project would have a less than
significant impact relative to operational air emissions.
Response d): Sensitive receptors are those parts of the population that can be severely
impacted by air pollution. Sensitive receptors include children, the elderly, and the infirm. The
residents located to the south of the project site are considered sensitive receptors. As
described below, the operations of the proposed project would not contribute substantial
concentrations of pollutants to sensitive receptors. The construction phase of the proposed
project has the potential to increase pollution concentrations that would impact sensitive
receptors.
Construction-Related Impacts on Sensitive Receptors: The construction phase of the project
would be temporary and short-term, and compliance with SCAQMD Rule 403 would greatly
reduce pollution concentrations generated during construction activities. Operation of the
proposed project would result in emissions primarily from vehicle trips, area sources, and
energy sources. As described under Response a) -c) above, the proposed project would not
generate significant concentrations of air emissions. Impacts to sensitive receptors during
construction would be negligible and this is a less than significant impact.
Toxic Air Contaminant Impacts on Sensitive Receptors: A toxic air contaminant (TAC) is defined
as an air pollutant that may cause or contribute to an increase in mortality or in serious illness,
or that may pose a hazard to human health. T ACs are usually present in minute quantities in the
ambient air. However, their high toxicity or health risk may pose a threat to public health even
at very low concentrations. In general, for those TACs that may cause cancer, there is no
concentration that does not present some risk. This contrasts with the criteria pollutants for
which acceptable levels of exposure can be determined and for which the state and federal
governments have set ambient air quality standards.
The California Air Resources Board (CARB) published the Air Quality and Land Use Handbook: A
Community Health Perspective (2007) to provide information to local planners and decision-
makers about land use compatibility issues associated with emissions from industrial,
commercial and mobile sources of air pollution. The CARB Handbook indicates that mobile
sources continue to be the largest overall contributors to the State's air pollution problems,
representing the greatest air pollution health risk to most Californians. The most serious
pollutants on a statewide basis include diesel exhaust particulate matter (diesel PM), benzene,
and 1,3-butadiene, all of which are emitted by motor vehicles. These mobile source air taxies
are largely associated with freeways and high traffic roads. Non-mobile source air taxies are
largely associated with industrial and commercial uses. Table 6 provides the CARB minimum
separation recommendations on siting sensitive land uses.

• Avoid siting new sensitive land uses within 1,000 feet of a major service and
Rail Yards maintenance rail yard.
• Within one mile of a rail yard, consider possible siting limitations and mitigation
approaches.
• Avoid siting of new sensitive land uses immediately downwind of ports in th e most
Ports heavily impacted zones. Consult local air districts or the CARBon the status of pending
analyses of health risks.
• Avoid siting new sensitive land uses immediately downwind of petr oleum refiner ies.

The proposed project does not include any source categories. Additionally, there are no source
categories listed above that are within screening distances or minimum separation distances
suggested for sensitive uses. SR 7 4 is the closest freeway and is located approximately 1.2 miles
(6,332 feet) from the project site. The project is consistent with the CARE Minimum Separation
Recommendations on Siting Sensitive Land Uses (2005). A health risk assessment is not
warranted for any further assessment. Implementation of the proposed project would not
result in an increased exposure of sensitive receptors to localized concentrations ofT ACs. This
project would have a less than significant impact relative to this topic.
Response e): The proposed project would not generate objectionable odors. People in the
immediate vicinity of construction activities may be subject to temporary odors typically
associated with construction activities (diesel exhaust, hot asphalt, etc.). However, any odors
generated by construction activities would be minor and would be short and temporary in
duration. Implementation of the proposed project would have a less than significant impact
relative to this topic.

A records search reveals that there are 56 special status plant species (federal/state listed,
and/or CNPS List 1B or 2) documented within the 9-quadrangle region search of the project
site. The records search was generated from the CNDDB, USFWS IPAC report, and CNPS
inventory (2 0 17). The full records are contained in Appendix C.
Field surveys were performed on March 30th and July 1Qth, 2017, which was intended to capture
the flowering season for special status plants documented within the region. At the time of the
surveys, the project site supported annual grassland and limited coyote brush. The annual
grasslands dominated the study area and consisted of non-native weedy grass species and
invasive annual species. The annual grassland area was degraded, and in several areas the land
was barren because of the site being used for parking. The coyote brush occurred on the site in
patches.
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
A historical analysis of the site showed that the site has been substantially altered as a result of
grading necessary to accommodate the existing San Juan Hills High School located immediate to
the west of the project site. Prior to the grading activities, annual grassland and coyote brush
communities occupied the site. There is a restoration area established as part of the Whispering
Hills Estates development project, which is located east of the project site (east of the SDG&E
easement). The project site is not located within the restoration areas.
The project site was devoid of sensitive habitat and does not contain any special status plants
that are documented in the region. Therefore, the proposed project would have a less than
significant impacts on special-status plants.
Special Status Animals
A records search reveals that there are 12 special status animals species (federal/state listed)
within the 9-quadrangle region search of the project site. The records search came from the
CNDDB, and USFWS IPAC report (2017). The full records are contained in Appendix C.
Reconnaissance-level field surveys were performed on March 30th and July 1Qth , 2017. Wildlife
observations were very limited during these field surveys, which is anticipated to be a result of
the grading disturbance and the current use of the site for parking. There was some evidence of
ground dwelling mammals during these surveys in the areas that were not heavily used for
parking. The project site was also surveyed in prior years, before the grading disturbance that
occurred with the San Juan Hills High School. It is noted in those surveys that there was a
variety of wildlife, including birds, amphibians, reptiles, and mammals that were observed or
expected to occur on the project site. This includes: mice, rats, gophers, squirrels, rabbits,
coyote, fox, skunk, raccoon, bobcat and deer. While none of these were observed during the
2017 surveys, there was evidence of burrows created by, or used by, mice, rats, gophers, and
squirrels. Presence of these species would also draw predators such as coyote, fox, skunk,
raccoon, and possibly bobcat. There is very limited habitat for deer under the current
conditions of the project site. The field surveys, both past and present, did not identify presence
of appropriate habitat for any of the special status animals that are documented in the region.
The project site did not contain any trees, and no tree nesting birds were observed within
proximity to the project site. The project site also did not contain any ground nesting birds, and
there was no evidence of present or past ground nesting. While no nesting was observed, each
nesting cycle (year) brings new potential for nesting. Any delay in construction into a future
year would present a new potential for impacts to nesting birds. Implementation of the
following mitigation measure would ensure that the project site is evaluated prior to the
commencement of construction if it were to occur during the nesting season. Additionally, the
following measure provides certain protections for nesting birds if they were found during the
preconstruction survey. Given the absence of observations of, or appropriate habitat for, special
status animals, and with implementation of the following measure, the proposed project would
have a less than significant impact on special-status animals.
Mitigation Measure Bio·l: Prior to any permit is suance for grubbing, grading, tree trimming/removal
or prior to engaging in such activities that would occur between the breeding season for native birds
(February 15 through july 31), the project applicant shall retain the services of a qualified ornithologist
to conduct an ornithological survey of the construction zone. The City will require the developer to
submit a copy of the executed contract for such services prior to the issuance of any grading permits.
The ornithological survey shall occur not more than seven days prior to the initiation of those
grading/construction activities. If the ornithologist detects any occup ied nests of native birds within the
construction zone or in close proximity to, they shall be mapped on construction plans and the project
applicant will fence of! the area(s) supporting bird nests with temporary construction fencing, providing
L PAGE44 J
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
a minimum buffer of 200 feet between the nest and limits of construction. {This buffer zone shall be at
least 500 feet for rap tors until the young have fledged, are no longer being fed by the parents, have left
the nest, and will no longer be impacted by the project.) The construction crew will be instructed to
avoid any activities in the zone until the bird nest(s) is/are no longer occupied, per a subsequent survey
by the qualified ornithologist. Alternatively, the project applicant will consult as appropriate with the
USFWS to discuss the potential loss of nests of native birds covered by the MBTA to obtain the
appropriate permit from the USFWS.
Indirect Effects on Special Status Species
Construction activities have a potential to result in indirect effects either to habitat or species
occupying areas outside the project site, including the Whispering Hills Estates revegetation
area to the west. Indirect effects involve the potentially harmful effects associated with noise
generated by construction equipment and dust created by the grading and site alteration
activities.
Given the distance from the project site to the revegetation area, noise and dust generated by
construction activities would not result in any significant indirect effects on special status
species located in the revegetation area. Construction activities would be subject to measures
that are intended to minimize noise and dust impacts (i.e. construction equipment fitted with
mufflers, dust control measures such as regular watering during grading). As a result, no
significant indirect impacts to special status species will occur. A SWPPP will be implemented
during construction to ensure that there are no indirect impacts to water bodies from storm
water runoff. This would, in effect, minimize any potential indirect effect on aquatic special
status species located off-site. Therefore, the proposed project would have a less than
significant impacts on special-status species.
Responses b-e): Riparian habitat is found in the interface between land and a river or stream.
This habitat is significant in ecology, environmental management, and civil engineering because
of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna
and aquatic ecosystems, including grassland, woodland, wetland or even non-vegetative.
Sensitive natural communities are those that are considered rare in the region, support special-
status plant or wildlife species, or receive regulatory protection (i.e., §404 and 401 of the Clean
Water Act, the CDFG §1600 et seq. of the California Fish and Game Code, and/or the Porter-
Cologne Act). In addition, the California Natural Diversity Data Base (CNDDB) has designated a
number of communities as rare; these communities are given the highest inventory priority
(Holland 1986, CDFG 2003e). There were 10 communities documented within the CNDDB
within a nine quad search. These included: Canyon Live Oak Ravine Forest, Southern Coast Live
Oak Riparian Forest, Southern Coastal Salt Marsh, Southern Cottonwood Willow Riparian
Forest, Southern Dune Scrub, Southern Foredunes, Southern Mixed Riparian Forest, Southern
Riparian Scrub, Southern Sycamore Alder Riparian Woodland, and Valley Needlegrass
Grassland. None of these habitat types are located within the project site.
The project site does not support any riparian habitat or sensitive natural communities.
Sensitive natural communities are not located on the project site. Therefore, implementation of
the proposed project would have a no impact relative to this issue.
Response d): The project site is currently undeveloped and does not serve as a wildlife
corridor, or nursery site. Although open space areas are located to the north and east of the
project site, movement of wildlife through the project site is currently limited by existing
development and roadways. For example, an existing school is located to the west of the project
site, and residential subdivision is located to the south of the project site. The proposed project
PAGE4Q
INt'11ALS'llUDY CHURCH OF }ESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
would 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. Implementation of the proposed project would result in
a less than significant impact relative to this topic.
Response e): The removal of native oak trees is regulated via the City's Tree Removal Permit
Ordinance. Section 9-2.349 of the City's Municipal Code defines heritage tree provisions and
outlines the procedures necessary to receive a tree removal permit. The project site, however,
does not contain any native oak trees. Therefore, implementation of the proposed project would
have no impact relative to this issue.
Response f): The project site is not located within an adopted Habitat Conservation Plan,
Natural Community Conservation Plan, or other approved local, regional, or state habitat
conservation plan. In July of 1996, the Orange County Central-Coastal Natural Communities
Conservation Plan (NCCP) Subregional Plan was adopted. However, the City of San Juan
Capistrano is not a signatory in the NCCP and the project site is not within the jurisdiction of the
NCCP or any other adopted Habitat Cons ervation Plan or Natural Community Conservation
Plan. Therefore, implementation of the proposed project would have no impact relative to this
issue.

on the site are historic in nature. As indicated in the Whispering Hills Estates Planned
Community Final EIR, two archaeological sites were also identified during the field surveys
conducted on the 470-acre Whispering Hills property. CA-ORA-25 was recorded in 1949 and
described as a Native American campsite that was said to lie close to the south bank of San Juan
Creek. The exact location of this site is unknown because it has not been observed since 1935.
No vestiges of CA-ORA-25 mapped within the Whispering Hills property could be found during
the field survey.
A second site, CA-ORA-243 was recorded within the Lacouague Ranch, approximately 4,200 feet
(0.8 mile) north of the Whispering Hills Estates Planned Community property, in 1967. Three
areas were defined in this archaeological site; however, in 1985, only one of the areas was
found. Areas 2 and 3 could not be located despite a thorough search of the Lacouague property.
The 1985 survey concluded that CA-ORA-243 was the remnant of an occupation site, which was
found to comprise a light to moderate scatter of prehistoric material covering an area of 15
acres. A thorough examination of the mapped location failed to yield any evidence that would
support the claim that a portion of the archaeological site CA-ORA-243 was located on the
Whispering Hills property. Furthermore, no additional isolated finds were discovered, despite a
comprehensive search of the area. In summary, no archaeological resource of any kind were
observed anywhere within the boundaries of the 470-acre Whispering Hills property.
The City of San Juan Capistrano General Plan does not identify the project site as having historic
buildings or structures, or prehistoric or historic archaeological resources. Additionally, there
are no known unique cultural, historical, paleontological or archeological resources known to
occur on, or within the immediate vicinity of the Project site. Furthermore, the site is not
designated as a historical resource as defined by Public Resources Code§ 21084.1, or listed in,
or eligible for listing in the California Register of Historical Resources.
The project site is currently vacant and has been previously graded to accommodate
development within the Whispering Hills Estates residential development and development of
San Juan Hills High School. No instances of cultural resources or human remains have been
unearthed on the project site during previous grading activities, and site visits have not
identified any historical, cultural, paleontological, or archeological resources present on site. It
is not anticipated that site grading and preparation activities would result in impacts to cultural,
PAGE 49
INJ.'J!IAI.SrtiDY CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
historical, archaeological or paleontological resources. However, as with most projects in
California that involve ground-disturbing activities, there is the potential for discovery of a
previously-unknown cultural or historical resource or human remains.
The implementation of the following mitigation measures would require appropriate steps to
pres erve andjor document any previously undiscovered resources t hat may be encoun t ered
during construction activities, including human remains. Implementation of this measure would
reduce any potential impact to a less than significant level.
Mitigation Measure Cul-1: A qualified archaeologist (defined as an archaeologist on the List of
Certified Archaeologists for Orange County) shall be retained by the project applicant and shall be
present at pre-construction meetings to advise construction contractors about the sensitive nature of
cultural resources located on andjor in the vicinity of the project site, as well as monitoring
requirements. A qualified monitor (defined as an individual with a bachelors degree in anthropology
with archaeological monitoring experience), supervised by the qualified archaeologist, shall observe on-
and off-site construction activities that result in grading, and/or excavating on or below the original
ground surface (including during project-related off-site utility [natural gas, electricity, sewer, water,
drainage, communications, etc.) and roadway improvements). Should nonhuman cultural resources be
discovered, the monitor shall have the power to temporarily halt or divert construction activities until
the qualified archaeologist can determine if the resources are significant and, if significant, until
recovered by the archaeologist. In the event that human remains are discovered, construction activities
shall be halted or diverted until the provisions of§7050.5 of the Health and Safety Code and §5097.98 of
the Public Resources Code have been implemented.
Mitigation Measure Cul-2: During construction/grading activities, a Native American monitor shall
observe construction/grading activities that result in grading, excavating, and/or trenching on or
below the original ground surface (including during project-related off-site utility [e.g., natural gas,
electricity, sewer, water, drainage, communications, etc.] and roadway improvements). The Native
American monitor shall consult with the archaeological monitor regarding objects and remains
encountered during grading that may be considered sacred or important. In the event that evidence of
human remains is discovered, the Native American monitor shall verifY that the archaeologist has
notified the Coroner.
Mitigation Measure Cul-3: If a significant Tribal Cultural Resource and/or unique archaeological
resource is inadvertently discovered during ground disturbing activities for this the project, the ]uanefio
Band of Mission Indians Acjachemen Nation OBMIAN) respectfully request avoidance as the preferred
method of preservation for archaeological, historical, paleontological and Tribal Cultural Resources
pursuant to California Public Resources Code Section 21083.2 (b). If however, it is demonstrated that
avoidance of a significant and/or unique cultural resource is infeasible, a data recovery plan shall be
prepared and submitted to the City of San juan Capistrano and the ]BMIAN.
Mitigation Measure Cul-4: If any prehistoric or historic artifacts, human remains or other indications
of archaeological or paleontological resources are found during grading and construction activities, an
archaeologist meeting the Secretary of the Interior's Professional Qualifications Standards in
prehistoric or historical archaeology, as appropriate, shall be consulted to evaluate the finds and
recommend appropriate mitigation measures.
• If cultural resources are identified, every effort shall be made to avoid the resources, with
preservation an important goal. If significant sites cannot feasibly be avoided, appropriate
measures, such as data recovery excavations or photographic documentation of buildings, shall be
undertaken consistent with applicable state and federal regulations. If the find is determined to be
be a tribal cultural resource and the discovered archaeological resource cannot be avoided, then
applicable mitigation measures for the resource shall be discussed with the geographically
affiliated tribe. Applicable mitigation measures that also take into account the cultural values and
meaning of the discovered tribal cultural resource, including confidentiality if requested by the
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT INITIALSWDY
tribe, shall be completed (e.g., preservation in place, data recovery program pursuant to PRC
§21083.2[i]). During evaluation or mitigative treatment, ground disturbance and construction
work could continue on other parts of the project site.
• If human remains are discovered, all work shall be halted immediately within SO meters (165 feet)
of the discovery, the County Coroner must be notified, according to Section 5097.98 of the State
Public Resources Code and Section 7050.5 of California's Health and Safety Code. If the remains are
determined to be Native American, the coroner will notify the Native American Heritage
Commission, and the procedures outlined in CEQA Section 15064.S(d) and (e) shall be followed.
• If any fossils are encountered, there shall be no further disturbance of the area surrounding this find
until the materials have been evaluated by a qualified paleontologist, and appropriate treatment
measures have been identified.

Background
A Geotechnical Review (Leighton and Associates, Inc., 2006) was prepared for the project site in
association with a previously proposed development. Additionally, an As-Graded Report of
Mass Grading (Leighton and Associates, Inc., 2007) was also prepared for the site. Further, a
Third Party Geotechnical Review Qohn R. Byerly, Inc., 2016) was prepared for the project. De
Novo Planning Group peer reviewed these reports for use in the Initial Study.
Responses to Checklist Questions
Responses a.i), a.ii), aiii): The project site is within the City of San Juan Capistrano, Orange
County, near the southeastern tip of the Santa Ana Mountains and south of the San Joaquin Hills.
As shown in Figure 12, the City is not located within and does not cross a delineated Alquist-
Priolo Earthquake Fault Zone. Additionally, mapped earthquake faults do not exist within the
City or the project site. All of Southern California, including the project site, is considered to be a
seismically active region. Seismic hazards that may affect the site include ground shaking,
PAGB52 J
CHURCH OF jESUS CHRIST OF LA TIER DAY SAINTS MEETINGHOUSE PROJECT INITIAL STUDY
liquefaction, and dynamic settlement. Due to lack of faults in the immediate vicinity of the
project site, other hazards such as ground rupture along a pre-existing fault of grounds lurching
are considered unlikely.
Liquefaction normally occurs when sites underlain by saturated, loose to medium dense,
granular soils are subjected to relatively high ground shaking. During an earthquake, ground
shaking may cause certain types of soil deposits to lose shear strength, resulting in ground
settlement, oscillation, loss of bearing capacity, landsliding, and the buoyant rise of buried
structures. The majority of liquefaction hazards are associated with sandy soils, silty soils oflow
plasticity, and some gravelly soils. Cohesive soils are generally not considered to be susceptible
to liquefaction. In general, liquefaction hazards are most severe within the upper 50 feet of the
surface, except where slope faces or deep foundations are present. Significant liquefaction
impacts are not anticipated, and mitigation would not be required.
In order to minimize potential damage to the buildings and site improvements, all construction
in California is required to be designed in accordance with the latest seismic design standards
of the California Building Code. The California Building Code, Title 24, Part 2, Chapter 16
addresses structural design and Chapter 18 addresses soils and foundations. Collectively, these
state requirements, which have been adopted by the City of San Juan Capistrano, include design
standards and requirements that are intended to minimize impacts to structures in seismically
active areas of California. Section 1613 specifically provides structural design standards for
earthquake loads. Section 1803.5.11 and 1803.5.12 provide requirements for geotechnical
investigations for structures assigned varying Seismic Design Categories in accordance with
Section 1613. Design in accordance with these standards and policies would reduce any
potential impact to the extent feasible. Absent any known faults, and because development of
the proposed project must be designed in conformance with state and local standards and
policies that limit risk from seismic shaking, any potential impact would be less than
significant.
Responses c), d): Expansive soils are those that undergo volume changes as moisture content
fluctuates; swelling substantially when wet or shrinking when dry. Soil expansion can damage
structures by cracking foundations, causing settlement and distorting structural elements.
Expansion is a typical characteristic of clay-type soils. Expansive soils shrink and swell in
volume during changes in moisture content, such as a result of seasonal rain events, and can
cause damage to foundations, concrete slabs, roadway improvements, and pavement sections.
Soil expansion is dependent on many factors. The more clayey, critically expansive surface soil
and fill materials will be subjected to volume changes during seasonal fluctuations in moisture
content. Figure 13 shows the soils within the Project site. The soils encountered at the site
consist of mainly Calleguas clay loam and Alo clay (9 to 15 percent slopes), with some Alo clay
(15 to 30 percent slopes) in the northern corner and some Cieneba sandy loam along the
eastern boundary. On-site areas where loose, sandy soils exist below the water table may be
subject to liquefaction in the event of a major earthquake. However, prior soil removal,
recompaction and the installation of canyon drains prior to fill placement as part of the adjacent
San Juan Hills High School and Whispering HUls project has significantly reduced the potential
for liquefaction impacts. The bedrock areas of the site are not susceptible to liquefaction
because of their high-density characteristics and lack of a shallow ground water table.
According to the As-Graded Report of Mass Grading (Leighton and Associates, Inc., 2007) the
expansion potential of the near-surface soils on the project site have a low to high expansion
potential. Additionally, results of laboratory corrosivity tests conducted by Leighton and
L PJ\GB53 J
JNlTIAbSTUDY CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
Associates indicate that concrete in contact with the existing on-site earth material is expected
to be subject to severe sulfate exposure. Ferrous metal components in contact with these soils
are expected to be subjected to a corrosive environment. The As-Graded Report of Mass Grading
contains measures to mitigate the potentially corrosive environment, including review of
corrosion test results by a corrosion specialist, individual testing for soluble sulfates, and
additional soil corrosion testing during future development of the site.
Based on the geotechnical conclusions, the proposed project would require proper geotechnical
design requirements to be incorporated into the building and improvement plans, and
additional soil testing to further define the geotechnical engineering requirements for the
individual structures. With implementation of the following mitigation measure, this potential
impact would be reduced to a less than significant level.
Mitigation Measure Geo-1 : Prior to earthmoving activities for the project, a certified geotechnical
engineer, or equivalent, shall be retained to perform a final geotechnical evaluation of the soils at a
design-level as required by the requirements of the California Building Code Title 24, Part 2, Chapter 18,
Section 1803.1.1.2 related to expansive soils and other soil conditions. The evaluation shall be prepared
in accordance with the standards and requirements outlined in California Building Code, Title 24, Part
2, Chapter 16, Chapter 17, and Chapter 18, which addresses structural design, tests and inspections, and
soils and foundation standards. The final geotechnical evaluation shall include design recommendations
to ensure that soil conditions do not pose a threat to the health and safety of people or structures,
including threats from landslides, unstable soils, expansive soils, or post-construction settlement. The
grading and improvement plans shall be designed in accordance with the recommendations provided in
the final geotechnical evaluation.
Response a.iv): There are several categories of landslides including: rockfalls, deep slope
failure, and shallow slope failure. Factors such as the geological conditions, drainage, slope,
vegetation, and others directly affect the potential for landslides. One of the most common
causes of landslides is construction activity that is associated with road building (i.e. cut and
fill). Figure 14 shows the landslide potential for the project site. As shown in the figure, the
project southern portion of the site is located within a landslide hazard zone. The project site is
in an area that was, prior to site grading, underlain by potentially compressible soils, ancient
landslide deposits, and Tertiary-aged Capistrano Formation. The report notes the potential for
reactivation of the offsite landslides is relatively low under current site conditions. In the event
the offsite landslide was reactivated, the failure would occur at the location of its lowest factor
of safety east of the project site and within the setback zone. A failure of this type would
typically manifest itself in the form of some bulging in the toe area of the landslide at its
weakest point and the setbacks recommended in the report (200 feet) provide a conservative
setback distance and to avoid potential impacts associated with unstable slopes.
The proposed project would be required to comply with all applicable development
requirements included in the Uniform Building Code. Additionally, Mitigation Measure Geo-1
requires submittal of a final geotechnical evaluation of the project before it is built. This
geotechnical evaluation would further refine the structural design, and would include design
recommendations for the proposed structures. This is a less than significant impact and no
mitigation is required.
Response b): The project site is currently undeveloped and is not at significant risk of erosion
under the existing conditions. Construction activities including grading could temporarily
increase soil erosion during and shortly after project construction if not properly managed.
Construction-related erosion could result in the loss of a substantial amount of nonrenewable
topsoil and could adversely affect water quality in nearby surface waters.

CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT (NJnAL STIJDY
The RWQCB requires a project specific Storm Water Pollution Prevention Plan (SWPPP) to be
prepared for each project that disturbs an area one acre or larger. The SWPPP includes project
specific best management measures that are designed to control drainage and erosion. The
proposed project includes detailed project specific drainage plan that control storm water
runoff and erosion, both during and after construction. This plan is subject to the review and
approval of the City through the improvement plan process.
A Preliminary Water Quality Management Plan (WQMP) was prepared for the project
(Commercial Development Resources, May 2017). The WQMP outlines the BMPs that will be
incorporated into the project, as well as mechanisms through which the BMPs will be
maintained.
The SWPPP, the WQMP, and the project specific drainage plan will manage storm water and
reduce the potential for erosion. Implementation of the following mitigation measure would
ensure that the proposed project would result in a less-than-significant impact relative to this
topic.
Mitigation Measure Geo-2: The project applicant shall submit a Notice of Intent (NO/) and Storm
Water Pollution Prevention Plan (SWPPP} to the RWQCB in accordance with the NPDES General
Construction Permit requirements. The SWPPP shall be designed to control pollutant discharges
utilizing Best Management Practices (BMPs) and technology to reduce erosion and sediments. BMPs
may consist of a wide variety of measures taken to reduce pollutants in storm water runoff from the
project site. Measures shall include temporary erosion control measures (such as silt fences, staked
straw bales/wattles, silt/sediment basins and traps, check dams, geofabric, sandbag dikes, and
temporary revegetation or other ground cover) that will be employed to control erosion from disturbed
areas. Final selection of BMPs will be subject to approval by the City of San juan Capistrano and the
RWQCB. The SWPPP will be kept on site during construction activity and will be made available upon
request to representatives of the RWQCB and City.
Response e): The proposed project would not require the use of septic tanks or alternative
waste water disposal systems for the disposal of waste water. Implementation of the proposed
project would result in no impact relative to this topic.

EXISTING SETTING
Background

Potentially Less Than Less Than Significant with No Significant Mitigation Significant Impact Impact Incorooratlon Impact
X

Various ga s es in the Earth's atmosphere, classified as atmospheric greenhouse gases (GHGs),
play a critical role in determining the Earth's surface temperature. Solar radiation enters
Earth's atmosphere from space, and a portion of the radiation is absorbed by the Earth's
surface. The Earth emits this radiation back toward space, but the properties of the radiation
change from high-frequency solar radiation to lower-frequency infrared radiation.
Naturally occurring greenhouse gases include water vapor (H zO), carbon dioxide (CO z),
methane (CH 4), nitrous oxide (NzO), and ozone (03). Several classes of halogenated substances
that contain fluorine, chlorine, or bromine are also greenhouse gases, but they are, for the most
part, solely a product of industrial activities. Although the direct greenhouse gases COz, CH 4,
and NzO occur naturally in the atmosphere, human activities have changed their atmospheric
concentrations. From the pre-industrial era (i.e., ending about 1750) to 2011, concentrations of
these three greenhouse gases have increased globally by 40, 150, and 20 percent, respectively
(IPCC, 2013).
Greenhouse gases, which are transparent to solar radiation, are effective in absorbing infrared
radiation. As a result, this radiation that otherwise would have escaped back into space is now
retained, resulting in a warming of the atmosphere. This phenomenon is known as the
greenhouse effect. Among the prominent GHGs contributing to the greenhouse effect are carbon
dioxide (CO z), methane (CH1), ozone (03), water vapor, nitrous oxide (NzO), and
chlorofluorocarbons (CFCs ).
The emissions from a single project will not cause global climate change, however, GHG
emissions from multiple projects throughout the world could result in a cumulative impact with
respect to global climate change. Therefore, the analysis of GHGs and climate change presented
in this section is presented in terms of the proposed project's contribution to cumulative
impacts and potential to result in cumulatively considerable impacts related to GHGs and
climate change.
Cumulative impacts are the collective impacts of one or more past, present, and future projects
that, when combined, result in adverse changes to the environment. In determining the
significance of a proposed project's contribution to anticipated adverse future conditions, a lead
agency should generally undertake a two-step analysis. The first question is whether the
combined effects from both the proposed project and other projects would be cumulatively
significant. If the agency answers this inquiry in the affirmative, the second question is whether
"the proposed project's incremental effects are cumulatively considerable" and thus significant
in and of themselves. The cumulative project list for this issue (climate change) comprises
PAGE63
INJTIALSTlJDV CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
anthropogenic (i.e., human-made) GHG emissions sources across the globe and no project alone
would reasonably be expected to contribute to a noticeable incremental change to the global
climate. However, legislation and executive orders on the subject of climate change in California
have established a statewide context and process for developing an enforceable statewide cap
on GHG emissions. Given the nature of environmental consequences from GHGs and global
climate change, CEQA requires that lead agencies consider evaluating the cumulative impacts of
GHGs. Small contributions to this cumulative impact (from which significant effects are
occurring and are expected to worsen over time) may be potentially considerable and,
therefore, significant.
Significance Thresholds
In 2008, the SCAQMD provided guidance to lead agencies on the determination of significance
of GHG project emissions. As part of the process, the SCAQMD assembled a GHG Significance
Threshold Working Group with the goal to develop and reach a consensus on acceptable
significance thresholds to be used in CEQA analyses for GHG emissions on an interim basis until
CARB (or another state agency) develops statewide guidance on assessing the significance of
GHG emissions under CEQA.
Initially, SCAQMD staff presented the GHG Significance Threshold Working Group with a
significance threshold that could be applied to various types of projects (residential, non-
residential, industrial, etc.). However, the threshold is still under development. In De cember
2008, staff presente d th e SCAQMD Governing Board with a significance threshold for stationary
source projects for which SCAQMD is the lead agency. This threshold uses a tiered approach to
determine a project's significance, with 10,000 metric tons of carbon dioxide equivalent
(MTCOze) as a screening numerical threshold for stationary sources. It should be noted that
when setting the 10,000 MTCOze threshold, the SCAQMD did not consider mobile sources
(vehicular travel), but rather stationary source generators such as boilers, refineries, power
plants, etc. Therefore, it would be misleading to apply a threshold that was developed without
consideration for mobile sources to a project where the majority of emissions are related to
mobile sources. Thus, there is no SCAQMD threshold that can be applied to the proposed
project.
In September 2010, the Working Group released additional revisions that consist of the
following recommended tiered approach in determining the significance of residential and
commercial projects as indicated in draft guidance issued by the SCAQMD, which includes:
• Tier 1: If the project is exempt under existing statutory or categorical exemptions there
is a presumption of "less-than-significant" impacts with respect to climate change.
• Tier 2: If the project's GHG emissions are within the GHG budgets in an approved
regional plan (plans consistent with CEQA sections 15064(h)(3), 15125(d), or
15152(s)), there is a presumption of "less-than-significant" impacts with respect to
climate change.
• Tier 3: Consists of screening values at the discretion of the lead agency; however, they
should be consistent for all projects within its jurisdiction. Project-related construction
emissions should be amortized over 30 years and should be added back the project's
operational emissions. The following thresholds are proposed for consideration:
o 3,000 MTCOze per year for all land use types; or
o 3,500 MTCOze per year for residential; 1,400 MTCOze per year for commercial;
or 3,000 MTC02e per year for mixed-use projects.
L PAGE64 ]
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT INITIAL STUDY
• Tier 4: Does the project meet one of the following performance standards? If yes, there
is a presumption of"less-than-significant" impacts with respect to climate change.
o Option 1: Reduce emissions from business as usual by a certain percentage
(currently undefined);
o Option 2: Early implementation of applicable AB 32 Scoping Plan measures; or
o Option 3: A project-level efficiency target of 4.8 MTC02e per service population
as a 2020 target and 3.0 MTCOze per service population as a 2035 target. The
recommended plan-level target for 2020 is 6.6 MTCO ze and the plan level target
for 2035 is 4.1 MTCOze.
• Tier 5: Involves mitigation offsets to achieve target significance thresholds (SCAQMD,
2010).
The SCAQMD has also adopted Rules 2700, 2701, and 2702 that address GHG reductions.
However, these rules address boilers and process heater, forestry, and manure management
projects, none ofwhich are required by the proposed project.
The City of San Juan Capistrano has not adopted its own numeric threshold of significance for
determining impacts with respect to GHG emissions, and relies upon the SCAQMD draft
screening level threshold. Therefore, for the proposed project, the 3,000 MT COze per year non-
industrial screening threshold is used for the significance threshold, in addition to the
qualitative thresholds of significance set forth below from Section VII of Appendix G to the
CEQA Guidelines.
RESPONSES TO CHECKLIST QUESTIONS
Responses a), b): The proposed project's short-term construction-related and long-term
operational GHG emissions for buildout of the proposed project, were estimated using the
California Emission Estimator Model (CalEEMod)™ (v.2016.3.1). CalEEMod is a statewide
model designed to provide a uniform platform for government agencies, land use planners, and
environmental professionals to quantify GHG emissions from land use projects. The model
quantifies direct GHG emissions from construction and operation (including vehicle use), as
well as indirect GHG emissions, such as GHG emissions from energy use, solid waste disposal,
vegetation planting and/or removal, and water use. Emissions are expressed in annual metric
tons of C02 equivalent units of measure (i.e., MTCOze ), based on the global warming potential of
the individual pollutants.
Short-Term Construction GHG Emissions
Estimated increases in GHG emissions associated with construction of the proposed project are
summarized in Table 7.
Table 7: Construction GHG Emissions (Unmitigated)
Year MTCOze
2017 82.6496
2018 265.4873
Maximum Per Year 265.4873
Overall Total 348.1369
30· Year Annual Amortized Rate 11.6046
SOURCE: CALEEMDD (V.2016.3 .1}.
[ PAGB65
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
As presented in the table, construction activities would generate 348.1369 MT CO ze total, which
is equivalent to 11.60 MT COze per year over a 30-year amortization period. Construction GHG
emissions would cease upon completion of the construction phase of the project and would
therefore be a small fraction of total project-related emissions when considering the longevity
of operation emissions associated with the project. Additionally, GHG emissions gen e r at ed by
construction activities can be reduced by reducing the amount of construction and demolition
waste generated by the project. To encourage recycling and salvaging of construction and
demolition debris, the City of San Juan Capistrano requires that a minimum of SO percent (as
measured by tonnage) of all construction demolition debris containing concrete and asphalt,
and 15 percent of all construction and demolition debris not containing concrete and asphalt be
diverted from landfills (City of San Juan Capistrano Municipal Code Section 6-3.08.01).
These construction GHG emissions are a one-time release and are comparatively much lower
than overall emissions associated with operational phases of a project. Construction GHG
emissions from the proposed project do not impede local GHG reduction efforts, or violate GHG
reduction goals set by AB 32, as required by the Public Resources Code, Section 21082.2.
Therefore, cumulatively these construction emissions would not generate a significant
contribution to global climate change.
Long-Term Operational GHG Emissions
The long-term operational GHG emissions estimate for buildout of the proposed project
incorporates the potential area source and vehicle emissions, and emissions associated with
utility and water usage, and wastewater and solid waste generation.
GHG emissions generated during the operational phase of the proposed project would include
emissions from transportation, energy, waste disposal, water consumption, and area sources.
GHG emissions from project-related operational activities are included in Table 8. For the
operational phase, the proposed project's GHG emissions are separated into emission sources
for the applicable GHG emissions sectors established by CARB. Mobile sector emissions are
emissions produced from vehicular travel to and from the project site. Energy sector emissions
include indirect sources of energy (electricity and natural gas). Area emissions include
emissions from landscaping activities. Solid waste emissions are generated by the
decomposition over time of trash sent to landfill. Water sector emissions are produced from the
transport of water to and from the project site. In general, transportation sector emissions
make up the largest proportion of emissions associated with a project. The second largest
source of emissions is from area sources.

CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
Overall GHG Emissions
As shown in Table 8, proposed project operations would generate approximately 341.6646 MT
C02e per year. In addition, as shown in Table 7, construction emissions (amortized over 30
years) would generate 11.6046 MT C02e per year. This results in a total of 353.2692 MT C02e
per year. The 3,000 MT C02e per year threshold established by the SCAQMD draft screening
level threshold would not be exceeded in either the mitigated or unmitigated scenarios.
Conclusion
As described above, the proposed project would not generate greenhouse gas emissions, either
directly or indirectly, that would have a significant impact on the environment. In addition, the
proposed project would not conflict with an applicable plan, policy or regulation adopted for
the purpose of reducing the emissions of greenhouse gasses. Therefore, there is a less than
significant impact relative to this topic.

Responses to Checklist Questions
Responses a), b): The proposed church would not routinely transport, use, or dispose of
hazardous materials, or present a reasonably foreseeable release of hazardous materials, with
the exception of common hazardous materials such as household cleaners, paint, etc. The
operational phase of the proposed project does not pose a significant hazard to the public or the
environment.
Onsite reconnaissance and historical records indicate that there are no known underground
storage tanks or pipelines located on the project site that contain hazardous materials.
Therefore, the disturbance of such items during construction activities is unlikely. Construction
equipment and materials would likely require the use of petroleum based products (oil,
L PAGE68
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT INITJALSTUDY
gasoline, diesel fuel), and a variety of common chemicals including paints, cleaners, and
solvents. Transportation, storage, use, and disposal of hazardous materials during construction
activities would be required to comply with applicable federal, state, and local statutes and
regulations. Compliance would ensure that human health and the environment are not exposed
to hazardous materials. Therefore, the proposed project would have a less than significant
impact relative to this issue.
Response c): The project site is within the % mile radius of the nearest school. The closest
school is San Juan Hills High School located opposite the private driveway, approximately SO
feet to the west of the project site. The operations of a church facility would not emit hazardous
emissions or result in the storage or handling of hazardous or acutely hazardous materials,
substances or waste other than common hazardous materials such as household cleaners, paint,
etc. Implementation of the proposed project would result in a less than significant impact
relative to this topic.
Response d): According the California Department of Toxic Substances Control (DTSC) there
are no Federal Superfund Sites, State Response Sites, or Voluntary Cleanup Sites on, or in the
vicinity of the project site. The project site is not included on a list of hazardous materials sites
compiled pursuant to Government Code§ 65962.5. The nearest investigation site includes:
• Solag Disposal Site (site # 30990002): This site, located at 31731 Paseo Adelanto
(approximately 2.7 miles west of the project site), is a Voluntary Cleanup Site which has
a status of No Further Action. The site was investigated for lead contamination because
of the previous uses of the site, which include truck storage and maintenance and
transfer of household recycled waste. No potential hazards have been identified with
this site.
Implementation of the proposed project would result in a less than significant impact relative
to this environmental topic.
Responses e), f): The Federal Aviation Administration (FAA) establishes distances of ground
clearance for take-off and landing safety based on such items as the type of aircraft using the
airport. The project site is not located within the vicinity of a private airstrip. The closest
airstrip is the John Wayne Airport approximately 18.5 miles northwest of the project site.
According to the Orange County Airport Land Use Commission (ALUC) Land Use Plan for John
Wayne Airport, the project site is not located within any of the safety zones. The project site is
not located within one mile of the airport, nor along the extended runway centerline. The
proposed project consists of one church building structure and one pavilion structure, and does
not propose any structures of substantial height that would protrude into active airspace.
Building height would be consistent with surrounding uses. Therefore, safety hazards related to
the project's proximity to airports are less than significant, and no mitigation is required.
Response g): The City of San Juan Capistrano has prepared an Emergency Preparedness Plan
that designates procedures to be followed in case of a major emergency. The plan identifies
resources available for emergency response and establishes coordinated action plans for
specific emergency situations and disasters, including earthquakes, fires, major rail and
roadway accidents, flooding, hazardous materials incidents, civil disturbance, and nuclear
disasters and attack. The project site is not designated for emergency use within the Emergency
Preparedness Plan .
PACE 69
JNI'J!IALS1'1JDY CHURCH OF }ESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
The primary concern in the Public Safety Element is risks to persons and personal property.
Development of the project site as proposed will not adversely affect either the evacuation
routes or the adopted emergency preparedness planning program(s) being implemented by the
City of San Juan Capistrano. The proposed project does not include any actions that would
impair or physically interfere with an adopted emergency response plan or emergency
evacuation plan. Implementation of the proposed project would result in no impact on this
environmental topic.
Response h): The risk of wildfire is related to a variety of parameters, including fuel loading
(vegetation), fire weather (winds, temperatures, humidity levels and fuel moisture contents),
and topography (degree of slope). Steep slopes contribute to fire hazard by intensifying the
effects of wind and making fire suppression difficult. Fuels such as grass are highly flammable
because they have a high surface area to mass ratio and require less heat to reach the ignition
point, while fuels such as trees have a lower surface area to mass ratio and require more heat to
reach the ignition point.
The California Department of Forestry has designated the eastern edge of the City, south of
Ortega Highway, as a Local Responsibility Area (LRA), which is within the very high fire hazard
severity zone; however, this rating does not extend to the project site. Additionally, the
proposed project would not include any habitable structures that would expose people to
significant ri sk of loss , injury, or death involving wildland fires. Because the project site is not
located within a designated wildfire hazard area, this is a less than significant impact and no
mitigation is required.

Responses to Checklist Questions
Response a): Implementation of proposed project would not violate any water quality or waste
discharge requirements. Construction activities including grading could temporarily increase
soil erosion rates during and shortly after project construction. Construction-related erosion
could result in the loss of soil and could adversely affect water quality in nearby surface waters.
The RWQCB requires a project specific SWPPP to be prepared for each project that disturbs an
area one acre or larger. The SWPPP is required to include project specific best management
PAGB71 ]
INITIAl. STUDY CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
measures that are designed to control drainage and erosion. A SWPPP has been prepared for
the project, and the SWPPP would be implemented throughout the construction phase of the
project. The SWPPP is designed to reduce the potential for the proposed project to violate water
quality standards during construction. The RWQCB requires regular monitoring and reporting
to ensure that the SWPPP is effectively controlling stormwater pollution. This is a regulatory
requirement that is required of all projects, and would mitigate the potential for an impact to
occur. Implementation of the proposed project would result in a less-than-significant impact
relative to this topic.
Response b): The proposed project would connect to the City of San Juan Capistrano water
system. The City of San Juan Capistrano Utilities Department provides water and wastewater
services to the project site. The Utilities Department derives its domestic water from three
sources: (1) 45 percent is purchased from the Metropolitan Water District of Southern
California (MWD) and consists of water from the Colorado River via the Colorado River
Aqueduct and Northern California water via the State Water Project; (2) approximately 44
percent of the City's water supply is produced by its Groundwater Recover Plant; and (3) the
remaining 11 percent is obtained from local groundwater wells located within the City.
The proposed project would not substantially deplete groundwater supplies or interfere
substantially with groundwater recharge such that there would be a net deficit in aquifer
vol u me 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). The project site is not a recharge site.
Project construction would add additional impervious surfaces to the project site; however, the
northern portion of the site would remain largely pervious, which would allow infiltration to
underlying groundwater. The water quality basin would continue to contribute to groundwater
recharge following construction of the project. In addition, the project is not anticipated to
significantly affect groundwater quality because sufficient stormwater infrastructure would be
constructed as part of project to detain and filter stormwater runoff and prevent long-term
water quality degradation. Therefore, project construction and operation would not
substantially deplete or interfere with groundwater supply or quality. This impact would be
less than significant.
Responses c-e): When land is in a natural or undeveloped condition, precipitation will
infiltrate/percolate the soils. Much of the rainwater that falls on natural or undeveloped land
slowly infiltrates the soil and is stored either temporarily or permanently in underground
layers of soil. When the soil becomes completely soaked or saturated with water or the rate of
rainfall exceeds the infiltration capacity of the soil, the rainwater begins to flow on the surface
of land to low lying areas, ditches, channels, streams, and rivers. Rainwater that flows off of a
site is defined as storm water runoff. When a site is in a natural condition or is undeveloped, a
larger percentage of rainwater infiltrates into the soil and a smaller percentage flows off the site
as storm water runoff.
The infiltration and runoff process is altered when a site is developed with urban uses. Houses,
buildings, roads, and parking lots introduce asphalt, concrete, and roofing materials to the
landscape. These materials are relatively impervious, which means that they absorb less
rainwater. As impervious surfaces are added to the ground conditions, the natural infiltration
process is reduced. As a result, the volume and rate of storm water runoff increases. The
increased volumes and rates of storm water runoff can result in flooding in some areas if
adequate storm drainage facilities are not provided.
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT JNITJALSTlJDY
There are no rivers, streams, or water courses located on or immediately adjacent to the project
site. As such, there is no potential for the project to alter a water course, which could lead to on
or offsite flooding. Drainage improvements associated with the project site would be located on
the project site, and the project would not alter or adversely impact offsite drainage facilities.
The proposed project would increase impervious surfaces throughout the project site. The
proposed project would require the installation of storm drainage infrastructure to ensure that
storm waters properly drain from the project site. The proposed storm drainage plan includes
an engineered network of storm drain lines, manholes, inlets, and a water quality basin. The
storm drainage plan was designed and engineered to ensure proper construction of storm
drainage infrastructure to control runoff and prevent flooding, erosion, and sedimentation. The
City Engineer reviews all storm drainage plans as part of the improvement plan submittal to
ensure that all facilities are designed to the City's standards and specifications. The City
Engineer also reviews all storm drainage plans to ensure that post-project runoff does not
exceed pre-project runoff. The City Engineer's review of pre-and post-project runoff is intended
to ensure that the capacity of the existing storm drainage system is not exceeded. This
determination is ultimately made by the City Engineer during the improvement plan review and
approval. Mitigation Measure Hydro-1 will require the post-project runoff to be equal to or less
than pre-project runoff, which would ensure that the proposed project would not substantially
increase the rate or amount of surface runoff in a manner which would result in flooding on-or
off-site. The storm drainage plan will require the construction of new storm water drainage
facilities on the project site; however, the construction of these facilities would not substantially
alter the existing drainage pattern of the area, or alter the course of a stream or river.
Implementation of the proposed project with the following mitigation measure would have a
less-than-significant impact relative to this environmental topic.
Mitigation Measure Hydro-1: The storm drainage plan shall be designed and engineered to ensure
that post-project runoff is equal to or less than pre-project runoff The applicant shall provide the City
Engineer with all storm water runoff calculations with the improvement plan submittal.
Response f): Construction activities including grading could temporarily increase soil erosion
rates during and shortly after project construction. Construction-related erosion could result in
the loss of soil and could adversely affect water quality in nearby surface waters. The RWQCB
requires a project specific SWPPP to be prepared for each project that disturbs an area one acre
or larger. The SWPPP is required to include project specific best management measures that are
designed to control drainage and erosion. A SWPPP has been prepared for the proposed project
and will be implemented throughout the construction phase of the project. Furthermore, the
proposed project includes a storm drainage plan that controls storm water runoff and erosion
after construction. The SWPPP and the storm drainage plan would reduce the potential for
polluted runoff and/or degradation of water quality. Implementation of the proposed project
would result in a less-than-significant impact relative to this topic.
Responses g-h): As shown in Figure 15, the project site is located within Flood Zone X, which is
not within the 100-year flood zone as shown on the Flood Insurance Rate Map (FIRM). The
closest 100-year flood zone is located to the north near San Juan Creek Road, outside of the
project site. Implementation of the proposed project would have no impact relative to this
environmental topic.
Response i): The project site is not located within an area with a control levee or dam. As
shown in Figure 16, the project site is not located within a dam inundation area. The proposed
project would not expose people or structures to a significant risk of loss, injury or death
PAGB73
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
involving flooding as a result of the failure of a levee or dam. Implementation of the proposed
project would have no impact relative to this environmental topic.
Response j): The project site is not anticipated to be inundated by a tsunami because it is
located at an elevation of 414 to 428 feet above sea level and is approximately 4.15 miles away
from the Pacific Ocean which is the closest ocean waterbody. Implementation of the proposed
project would have no impact relative to this environmental topic.
The project site is not anticipated to be inundated by a seiche because it is not located in close
proximity to a water body capable of creating a seiche. Implementation of the proposed project
would have no impact relative to this environmental topic.
A mudflow is a category of landslide that is associated with heavy saturation of soils and
sometimes is associated with seismicity. Factors such as the geological conditions, drainage,
slope, vegetation, and others directly affect the potential for mudflow. The City's General Plan
EIR does not identify mudslides as a topic of concern. Additionally, the project site is essentially
flat and would be graded as part of the project. No steep areas that would have the potential to
generate mudflows during operations would be created. Therefore, implementation of the
proposed project would have no impact relative to this environmental topic.

c) Conflict with any applicable habitat conservation X plan or natural community conservation plan?
Responses to Checklist Questions
Response a): The proposed project includes development of church uses on an undeveloped
site that is surrounded by residential uses, a public school, and open space. The proposed public
church is consistent with the surrounding uses and would not physically divide an established
community. Implementation of the proposed project would have a less than significant impact
relative to this topic.
Response b): The key planning documents that are directly related to, or that establish a
framework within which the proposed project must be consistent, include:
• City of San Juan Capistrano General Plan
• City of San Juan Capistrano Zoning Ordinance
The project site currently has a Planned Community (PC) General Plan Land Use Designation
and PC Zoning Designation. The PC designation denotes large areas of land under single or
common ownership for detailed planning and development for residential, commercial,
industrial, public/institutional, recreation, and open space uses. The Whispering Hills Estates
PC zone, however, envisioned single family residential uses on the project site. The applicant
has proposed to amend CDP 04-01 to allow the proposed church use with a Conditional Use
Permit. The church use is being reviewed based on the CDP 04-01 proposed amendment.
Approval of the code amendment and conditional use permit would create consistency between
the General Plan and Zoning Ordinance for the project site.
The proposed code amendment does not cause a significant physical environmental impact. The
purpose of the code amendment and Conditional Use Permit is to ensure that the project does
not conflict with applicable Zoning. The project, as proposed, would not conflict with any
applicable land use plan, policy, or regulation of the City. Implementation of the proposed
project would have a less than significant impact relative to this issue.
Response c): The project site is not located within an adopted Habitat Conservation Plan,
Natural Community Conservation Plan, or other approved local, regional, or state habitat
conservation plan . In July of 1996, the Orange County Central-Coastal NCCP Subregional Plan
was adopted. However, the City of San Juan Capistrano is not a signatory in the NCCP and the
project site is not within the jurisdiction of the NCCP or any other adopted Habitat Conservation
Plan or Natural Community Conservation Plan. Therefore, implementation of the proposed
project would have no impact relative to this issue.

Responses to Checklist Questions
Response a): The California Geological Survey (CGS) has mapped mineral and mineral
aggregate resources in Orange County. The MRZ-1 designation covers the site and the
surrounding area, a designation defined as "areas where adequate information indicates that no
significant construction aggregate deposits are present, or where it is judged that little
likelihood exists for their presence" (CDMG, 1995). No mineral extraction operations exist at
the property. Additionally, there are no oil and gas extraction wells within or near the property.
Implementation of the proposed project would have no impact relative to this issue.
Response b): The project site does not contain a locally-important mineral resource recovery
site delineated on a local general plan, specific plan or other land use plan. The proposed
project would not result in loss of a mineral resource. Implementation of the proposed project

Background
A Noise Impact Analysis (2017) was prepared by Giroux & Associates for the proposed project.
The following is a summary of the report, which is contained in Appendix D.
Regulatory Framework
City o(San luan Capistrano Gen eral Plan Noise Elem ent: The City of San Juan Capistrano General
Plan Noise Element establishes noise standards for land use categories based on the State of
California Office of Noise Control land use compatibility recommendations. Table 9 shows the
community noise exposure recommended as normally acceptable, conditionally acceptable,
normally unacceptable, and clearly unacceptable for various classes of land use sensitivity. The
City guidelines recommend an exterior noise exposure of less than 60 dB CNEL for churches.
Church development with noise exposures of up to 65 dB CNEL are considered "conditionally
acceptable" and may be permitted if noise mitigation is included in the design. Noise levels
between 70 and 80 dB CNEL are considered to be "normally unacceptable". Compatibility
standards have a dual purpose. For outdoor assembly areas, an exterior exposure of 65 dB
CNEL allows for intelligible conversation without noticeable interruption. Structural noise
attenuation in air-conditioned non-residential structures with fixed sash windows is typically
30 to 35 dB. When exterior levels are 65 dB CNEL or less, interior levels in such buildings are
generally 30 to 35 dB CNEL. Levels of less than 45 dB CNEL are normally considered wholly
unobtrusive into noise sensitive uses such as prayer, reading, contemplation, etc. An exterior
L PAG£81
INili'IALSTUDY CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
ambient noise level of 65 dB CNEL or less is considered to not create a noise constraint for the
proposed project.

Stationary noise standards are typically articulated in the jurisdictional Municipal Code. These
standards recognize the varying noise sensitivity of both transmitting and receiving land uses.
The property line noise performance standards are normally structured according to land use
and time-of-day. They apply mainly to mechanical equipment or to nuisance sources such as
amplified voice or music.
Cit;y ofSan /uan Capistrano Municipal Code: The City Noise Ordinance (Section 9-3.531 of the
City's Municipal Code) is designed to protect people from non-transportation (stationary) no is e.
The Noise Ordinance for the City of San Juan Capistrano sets limits on the level and the duration
of time a stationary noise source may impact an adjoining residential use as shown in Table 10
and summarized below.
For a sensitive land use zone, the noise standards at the residential property line are as follows:
• 7:00a.m. to 7:00p.m.: 65 dBA
• 7:00p.m. to 10:00 p.m.: 55 dBA
• 10:00 p.m. to 7:00a.m.: 45 dBA

The City's noise ordinance limits are stated in terms of a 30-minute limit with allowable
deviations from this 50th percentile standard. The louder the level becomes, the shorter the time
becomes that it is allowed to occur with a maximum of +20 dB for less than one minute per
hour. Table 10 lists the noise level and the maximum cumulative period of time that the noise
level may occur during a one-hour period.
The standards in Table 10 apply at any residential property line. However, the ordinance
identifies events which are exempt from the provisions of the noise restrictions. According to
the code, school bands, school athletic and school entertainment events are exempt from the
standards.
The code also exempts construction noise from the ordinance standards as long as construction
occurs from 7:00a.m to 6:00p.m. Monday through Friday or 8:30a.m. to 4:30p.m. on Saturday.
Construction is not permitted on Sundays or federal holidays.
The closest noise-sensitive daytime uses are the adjoining high school. Although the campus is
not specifically protected from construction activity noise by the City' noise ordinance, where
feasible, the grading contractor should coordinate with management of the school facilities to
schedule the noisiest activities during periods of lesser sensitivity. The closest residence is
located approximately 450 feet to the south of the project site, opposite Vista Montana.
Baseline Noise Levels
Noise measurements were made in order to document existing baseline levels in the area. The
measurements help to serve as a basis to determine noise exposure from ambient noise
activities upon the proposed project. In year 2013, for a previously proposed residential
project, Giroux & Associates conducted long term (24-hour) noise measurements on Tuesday,
January 15, to Wednesday, January 16, at four locations on the site, as shown in Figure 17.
Because the measurements were several years old, short term noise measurements were made
on Thursday, May 10, 2017, between the hours of 2 :00p.m. and 2:55p.m. atthe same locations
to verify consistency.
PAGE83 J
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
The short-term results are shown in Table 11 and the long-term monitoring results are shown
in Table 12. Sites 2 and 4 were almost identical in 2013 and 2017. Site 1 was slightly louder in
2013, but had active nearby tennis practice in 2013 but not in 2017. Baseline noise levels have
changed negligibly in the last five years.

In both 2013 and 2017, audible daytime noise sources included student athletic activity on the
tennis courts, occasional traffic on Stallion Ridge, formerly Vista Montana, distant trash trucks
rumbling on La Pata Avenue, and a low frequency hum and rumble from the tub grinder at the
greenwaste recyclingjcomposting facility on La Pata Avenue. Humidity was too low to generate
any hissing noise from the power line conductors.
Monitoring experience shows that 24-hour weighted CNEL's are approximately equal to mid-
day Leq plus 2 to 3 dB (Caltrans Technical Noise Supplement, 2009). At Meter 1, located at the
northwest corner of the project site directly across from the high school tennis courts, observed
PAGI! 84
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT JNITJALSJ'UDY
noise levels were almost 58 dB CNEL in 2013. The short-term noise measurement in 2017 of 47
dB Leq would translate to a CNEL of about 50 dB. Further south, across from the baseball field,
noise levels at Meter 2 were less than 53 dB CNEL in 2013 and adjusting the 2017 short-term
measurement to a CNEL would yield almost the same results. Along Vista Montana closer to La
Pata Avenue, noise levels at Meter 4 were approximately 57 dB CNEL.
Nevertheless, all these readings demonstrate that existing noise levels are well within the City's
compatibility thresholds for religious facility noise/land use, even closest to travel routes
(School Access Road and Stallion Ridge). The combined effects of existing traffic noise as well as
student activity are well within "conditionally acceptable" compatibility criteria and likely
within the "normally acceptable" range and do not pose a noise constraint for the proposed use.
Standards of Significance
Noise impacts are considered significant if they expose persons to levels in excess of standards
established in local general plans or noise ordinances. The exterior noise standard for the City
of San Juan Capistrano for sensitive uses is 65 dBA CNEL in usable outdoor space. If required,
attenuation through setback and project perimeter barriers is anticipated to be used to reduce
traffic noise to the 65 dBA CNEL goal. However, an inability to achieve this goal through the
application of reasonably available mitigation measures would be considered a significant
impact.
Impacts may also be significant if they create either a substantial permanent or temporary
increase. The term "substantial" is not quantified in CEQA guidelines. In most environmental
analyses, "substantial" is taken to mean a level that is clearly perceptible to humans. In practice,
this is at least a 3 dB increase. Some agencies, such as Cal trans, require substantial increases to
be + 10 dB or more if noise standards are not exceeded by the increase. For purposes of this
analysis, a 3 dB increase is considered a substantial increase. The following noise impacts due
to project-related traffic would be considered significant:
1. If construction activities were to audibly intrude into adjacent uses south of the site or
educational activities west of the site during periods of heightened noise sensitivity.
2. If project traffic noise were to cause an increase by a perceptible amount ( +3 dB CNEL)
or expose receivers to levels exceeding City of San Juan Capistrano compatibility noise
standards.
3. If future cumulative build-out noise levels were to expose sensitive receivers to levels
exceeding City of San Juan Capistrano compatibility standards of 65 dB CNEL exterior at
any outdoor uses or 45 dB CNEL interior noise levels in any habitable space.
Vibration Standards
Vibration is like noise in that it involves a source, a transmission path, and a receiver. While
vibration is related to noise, it differs in that noise is generally considered to be pressure waves
transmitted through air, whereas vibration usually consists of the excitation of a structure or
surface. As with noise, vibration consists of an amplitude and frequency. A person's perception
to the vibration will depend on their individual sensitivity to vibration, as well as the amplitude
and frequency of the source and the response of the system which is vibrating.
Vibration can be measured in terms of acceleration, velocity, or displacement. A common
practice is to monitor vibration measures in terms of peak particle velocities in inches per
second. Standards pertaining to perception as well as damage to structures have been
L PAGB85
INITIAL STUDY CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
developed for vibration levels defined in terms of peak particle velocities. The City of San Juan
Capistrano does not have specific policies pertaining to vibration levels. However, vibration
levels associated with construction activities are addressed as potential noise impacts
associated with project implementation.
Human and structural response to differen t vibration levels is influenced by a number of
factors, including ground type, distance between source and receptor, duration, and the number
of perceived vibration events. The threshold for damage to structures ranges from 0.2 to 0.6
peak particle velocity in inches per second (in/sec p.p.v). The general threshold at which human
annoyance could occur is notes as 0.1 in/sec p.p.v.

Vehicular Noise Impacts
Long-term noise concerns from the increased urbanization of the project area center primarily
on mobile source emissions surrounding the project site. These concerns were addressed using
the California specific vehicle noise curves (CALVENO) in the Federal Highway Administration
(FHWA) noise prediction model (FHWA-RD-77-108) in a computerized version of the model
developed by Caltrans. The model calculates the LE Q noise level for a particular reference set of
input conditions, a nd t h en makes a series of adjustments for s ite-specific traffic volumes,
distances, speeds, or noise barriers.
Tables 13 and 14 summarize the 24-hour CNEL level at SO feet from the roadway centerline
along area roadway segments. Four traffic scenarios were evaluated: "Existing", "Existing Plus
Project", "Opening Year (2017) No Project" and "Opening Year (2017) Plus Project". The noise
analysis utilized data from the traffic analysis prepared for the proposed project by KOA
Corporation in June 2016.

Traffic attributed to the proposed project would only slightly increase the total traffic traveling
along the major thoroughfares within the project vicinity because of the small amount of
weekday trips generated by the project. The project would generate lS 1 new daily trips on
weekdays and 607 new daily trips on weekends.
Elevated non-project traffic levels on area roadways will substantially mask any small project
noise contribution. As seen in Table 14, no "detectable" project-related noise increases will
occur on any analyzed roadway segment. The largest weekday project impact is on School
Access Road, but this increase is only +O.S dB which is below the threshold of perception.
Cumulative impacts are defined as the difference between the "future with project and other
area development" scenario and "existing" noise levels. The largest cumulative impact is +0.6
dB CNEL, which would also occur on School Access Road. This cumulative increase in noise
levels would be below the threshold of perception.
On weekends, the project will generate 607 new daily trips; however, the adjacent high school
would typically be closed on weekends. The only uses that could be negatively impacted by the
weekend trips are the homes south of Stallion Ridge offVia Zamora Road.
The project report provides the following weekend hourly peak vehicle volumes which would
create the indicated Sunday morning peak hour noise increase:

SOURCE: GIROUX & ASSOCIATES, 2017.
During the peak weekend hour, project traffic could create up to a +2.2 dB hourly increase
at SO feet from the roadway centerline. The remaining weekend hours will have a much
lesser impact. Regardless, all the homes located south of the project site are at least 100
feet from the Stallion Ridge centerline. This would attenuate noise levels by 4.S dB due to
distance. Thus, the peak hour traffic noise level of 62.S dB at SO feet from centerline would
be reduced to 58 dB at the closest property line south of Stallion Ridge. These increases
[ PAG1!87 J
JNJ'I'IALSTUDY CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
would most likely not be audible at the adjacent homes and are much less than the +3.0 dB
significance threshold or the 65 dB CNEL compatibility recommendation.
Because the noise/land use compatibility standards are based upon the weighted 24-hour
CNEL metric, whereas peak traffic noise resulting from the proposed project would occur
during single site access and departure hours, changes to CNEL levels seen in Tables 15
and 16 would be negligible.
On-Site Noise Sources
Operation of the proposed project is not considered a potentially significant noise generator.
The closest residential sensitive receptor is approximately 450 feet south of the proposed
church building. It is noted that the proposed parking lot is setback even farther from the
nearest residence.
Parking lot activities will be sporadic with a peak on Sundays. According to the project traffic
report, the Sunday peak hour traffic volume would be 200 vehicles (100 inbound and 100
outbound). Th e r e ference noise level at SO feet for 200 vehicles with a 25 miles per hour (mph)
travel speed is 53 dB Leq· At 400 feet, this noise level is attenuated to 39 dB Leq· This is less than
the City daytime noise standard of 65 dB for 30 minutes.
The outdoor pavilion would be used for congregational picnics with under 75 adults and
children, and smaller youth gatherings such as Cub Scout Troop activities, or other similar teen
discussions. The aforementioned congregational picnics and other youth activities would occur
on a few occasions during the year, usually on Tuesday or Wednesday evenings. Events for
elementary school aged children would occur between 4 :00 PM and 6:30 PM, and events for
youth and/or adults would occur between 7:00PM and 8:30 PM. The outdoor pavilion area is
not anticipated to host concerts or other similar events which would attract large crowds or
would require amplified music. The congregation activities with 75 or fewer attendees would
occur once or twice a year on a Saturday afternoon.
Because the pavilion would be located north of the proposed church building, separation
distance and the intervening church building would attenuate possible pavilion noise at the
closest residential area south of the project site. The pavilion would be located near the
proposed bio-retention basin, which is over 100 feet from the adjacent high school.
Because of the distance to the nearest off-site sensitive receptor as well as probable low parking
lot traffic speed, it is improbable that any potential noise nuisance would result. Additionally,
none of the limited pavilion activities would result in significant noise generators. Noise
associated with the proposed church operations would be sufficiently below the noise baseline.
Because the majority of the church services would be conducted during day time hours and
held indoors, no disturbance during noise sensitive sleeping hours would occur. It is not
anticipated that adjacent sensitive uses will notice any change in the noise environment.
Because the adjacent high school is closed on weekends, there would be no disruption to
operations at the school.
On-Site Noise Exposure
The proposed project includes addition of devotional space. Exterior noise standards for church
and school use are ideally less than 60 dB CNEL, though less than 65 dB is considered
"conditionally acceptable".
PAGR81l
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT INITIAL STUDY
The major noise source potentially affecting the proposed church would be traffic from La Pata
Avenue. The closest new sanctuary fa~;ade is 380 feet to the La Pata Avenue centerline. At this
distance, the 70 dB CNEL noise level at 50 feet would be attenuated to 56 dB CNEL.
Noise reductions of 25 to 30 dB is normally attainable with closed, dual-paned windows in
newer construction or modular buildings. This would reduce any traffic-related CNEL to below
26 to 31 dB CNEL for interior use in any proposed rooms facing La Pata Avenue. Therefore,
there are no existing or future noise constraints relative to City of San juan Capistrano noise
standards for the proposed project.
Conclusion
Project-related traffic will have a less then significant impact on sensitive receptors. Project-
related traffic or cumulative development will not cause noise standards to be exceeded, nor
make any existing noise levels measurably worse. Maximum on-site traffic and parking
activities during peak weekend traffic hour use will not exceed significance criteria at the
nearest residential property line. Surrounding perimeter roadways do not pose a development
constraint for project development as proposed. Consequently, the project would result in a
less than significant impact relative to this topic.
Response b): Typical background vibration levels in residential areas are usually 50 vibration
decibels (VdB) or lower, below the threshold of human perception. Perceptible vibration levels
inside residences are typically attributed to the operation of heating and air conditioning
systems, door slams, or street traffic. Construction activities and street traffic are some of the
most common external sources of vibration that can be perceptible inside vibration sensitive
uses.
Construction activities generate groundborne vibration when heavy equipment travels over
unpaved surfaces or when it is engaged in soil movement. The effects of ground borne vibration
include discernable movement of building floors, rattling of windows, shaking of items on
shelves or hanging on walls, and rumbling sounds. Vibration related problems generally occur
due to resonances in the structural components of a building because structures amplify
ground borne vibration. Within the "soft" sedimentary surfaces of much of Southern California,
ground vibration is quickly damped out. Groundborne vibration is almost never annoying to
people who are outdoors in the region (FTA 2006).
Groundborne vibrations from construction activities rarely reach levels that can damage
structures. Because vibration is typically not an issue, very few jurisdictions have adopted
vibration significance thresholds.
Vibration is most commonly expressed in terms of the root mean square (RMS) velocity of a
vibrating object. RMS velocities are expressed in units of vibration decibels. The range ofVdB is
as follows:
• 65 VdB: threshold of human perception
• 72 VdB: annoyance due to frequent events
• 80 VdB: annoyance due to infrequent events
• 94-98 VdB: minor cosmetic damage
BAGH89
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
To determine potential impacts of the project's construction activities, estimates of vibration
levels induced by the construction equipment at various distances are presented below:
Table 16: Vibration Levels for Vatying Construction Equipment
Approximate Vibration Levels (VdB)
Equipment 25 feet 50 feet 100 feet 200/eet 400feet
Large Bulldozer 87 81 75 69 63

Jackhammer 79 73 67 61 55
Small Bulldozer 58 52 46 40 34
SOURCE: FEDERAL TRANSIT ADMINISTRATION, TRANSIT NOISE AND VIBRATION IMPACT ASSESSMENT GUIDELINES, MAY 2006
The on-site construction equipment that will create the maximum potential vibration is a large
bulldozer. The stated vibration source level in the Federal Transit Administration (FTA)
Handbook for such equipment is 81 VdB at SO feet from the source. With typical vibration
energy spreading loss, the annoyance threshold of 80 VdB is met at 56 feet. High school
recreational uses are closest to the project site, but, as noted above, groundborne vibration is
almost never annoying to people who are outdoors. Any vibration perception such as rattling
windows would only occur in classrooms. The closest classrooms at the school are more than
400 feet from any of the proposed major grading areas. At this distance, vibration levels decay
to 63 VdB, which is less than the threshold of perception. Therefore, construction vibrations are
not predicted to cause damage to existing buildings or cause annoyance to sensitive receptors.
This impact would be considered less than significant.
Response d): Temporary construction noise impacts will vary markedly because the noise
strength of construction equipment ranges widely as a function of the equipment used and its
activity level. Short-term construction noise impacts tend to occur in discrete phases dominated
initially by demolition of existing structures and large earth-moving sources, then by
foundation and parking lot construction, and finally for finish construction. The earth-moving
sources are the noisiest, with equipment noise typically ranging from 75 to 90 dBA at 50 feet
from the source.
Table 17 shows the range of noise emissions for various pieces of construction equipment.
Point sources of noise emissions are attenuated by a factor of 6 dB per doubling of distance
through geometrical (spherical) spreading of sound waves. The quieter noise sources will drop
to a 65 dBA exterior f 45 dB A interior noise level by about 200 feet from the source while the
loudest may require over 1,000 feet from the source to reduce the 90+ dBA peak source
strength to a generally acceptable 65 dBA exterior exposure level. This estimate assumes a clear
line-of-sight from the source to the receiver. The sustained average noise level over any
averaging period is usually considerably lower because of variable power levels and equipment
mobility. The hourly average noise level is typically measured at 80 dBA near any semi-
stationary heavy equipment. Variations in terrain elevation or existing structures will also act
as noise barriers that may interrupt equipment noise propagation. Construction noise impacts
are, therefore, somewhat less than that predicted under idealized input conditions
According to the City of San Juan Capistrano Municipal Code, permissible hours of construction
are 7 a.m. to 6 p.m. on weekdays and on 8:30 a.m. to 4:30 p.m. on Saturdays. Construction is not
permitted on any national holiday or on any Sunday. Although the noise ordinance does not
specifically identity school uses as meriting construction noise protection, heavy equipment
noise may be intrusive into indoor learning and outdoor recreational use. The construction
activities may occur as close as 480 feet to the nearest classroom. Peak noise levels at 90 dB at
PAGE"90
CHURCH OF )ESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT INITIAl. STUDY
SO feet will be reduced to 70 dB at the nearest classroom fa~ade. Student outdoor assembly
areas at the high school occur within a sheltered courtyard located even farther from planned
construction. The outdoor assembly areas area also separated from the project site by the
school building itself. Any possible construction activity noise constraint would be to the
interior instructional environment. Because the classrooms are air conditioned, the structural
attenuation of rooms with heavy duty plate windows is 30 dB or more. A typical indoor
classroom hourly noise level is 55 dBl. Project construction activities would cause indoor
classroom noise levels of 40 dB or less, which would not be considered intrusive.

The high school baseball field and tennis courts are located within a zone of possible
construction noise impact. The tennis courts are as close as 120 feet from the edge of the
project site. Third base at the baseball field is approximately 250 feet away from the site. The
portion of the site closest to the tennis courts is a steep hill that has already been contour-
graded. The closest point of site grading near the tennis courts is also around 250 feet from
physical education or tennis practice activities.
At 250 feet, the hourly average equipment noise level would be 66 dB under direct line of sight
(80 dB at SO feet minus 14 dB distance spreading loss). An outdoor noise level of 70 dB is
considered by the EPA to be excessive for active outdoor recreational uses. At 66 dB, the noise
may be audible, but will not substantially interfere with activities where players, coaches, or
spectators often raise their voices themselves at well above equipment noise levels. Therefore,
construction noise levels are not predicted to cause annoyance to sensitive receptors. This
impact would be considered less than significant.
Response e, f): The project site is located within an airport land use plan and, within two miles
of a public airport or public use airport. The closest airstrip is the John Wayne Ai r po r t, located
approximately 18.5 miles northwest of the project site. According to the Orange County ALUC
Land Use Plan for John Wayne Airport, the project site is not located within any of the safety
zones. Therefore, implementation of the proposed project would result in no impact relative to
this topic.

Fire protection services and facilities in the City of San Juan Capistrano are provided and
maintained through a contract with the OCFA. Fire protection service is essential to the safety of
the residents in the City, especially with the threat of wildfires. Services provided by the OCFA
include structural fire protection, emergency medical and rescue services, hazardous
inspections and response, and public education activities. OCFA also participates in disaster
planning as it relates to emergency operations, which includes high occupant areas and school
sites; and the agency may participate in community disaster drills planned by others. Since fire
protection is provided under contract, the City must be involved in close coordination with the
OCFA to ensure that appropriate levels of service are provided to the community.
Orange County Fire Station #56, which is located at 56 Sendero Way, is the nearest fire station
to the project site (1.9 miles north). Additionally, Fire Station #7, which is located at 31865 Del
Obispo, serves the City of San Juan Capistrano. This station is located approximately 2.3 miles
west of the project site. At the present time, the OCFA Board of Directors has adopted a
response time standard intended to maintain adequate levels of service. That standard requires
that the first unit must be on-scene from receipt within seven minutes and 20 seconds 80
percent of the time. OCFA has assigned a 12-minute response for a full first alarm assignment
(i.e., three engines, one truck, one medic, and one chief) 80 percent of the time; the first unit
equates to a five-minute drive time.
In 2015, the OCFA responded to 6,862 incidents in San Juan Capistrano. Additionally, the actual
total response time for the City during 2012 at the 90th percentile was approximately eight
minutes and 49 seconds. The OCFA's independent Insurance Services Office (ISO) rating (a
rating which can be used to assess the effectiveness of fire protection services) varies by
community. The OCFA is divided into six ISO regions and rating areas (OC Central, East, North,
South, and West and Santa Ana). The project site is located in the South region. The South
region has a Class 3 rating. The majority of the populated areas of OCFA have a Class 3 rating. A
portion of the Eastern Region is a Class 4 rating. The canyon areas and Cleveland National
Forest are rated a class 9. The City expands fire protection services as growth and development

occurs to meet the adopted fire response time as a general guideline. (General Plan Policies 2.1,
and 2.2 [Public Services & Utilities Element], and Policy 1.1 [Growth Management Element].
Funding for fire operations and services is derived from a combination of development impact
fees and the City's General Fund. Development impact fees are paid prior to construction and
are typically used to fund new facilities and equipment, while the General Fund (revenues from
property tax and sales tax) is typically used to fund ongoing fire operations.
The proposed project would not result in a need to construct a new fire station or physically
alter an existing fire station. As previously stated, the OCFA would receive development impact
fees for capital improvements and infrastructure costs even though a new facility would not be
created. The fair share funds are intended to pay for project financial impacts on fire protection
service. The proposed project's environmental impact to fire service is considered less than
significant.
Police Protection
The City of San Juan Capistrano has been contracting its primary law enforcement services from
the OCSD since 1961. The OCSD, which maintains facilities in the existing Dance Hall building at
32400 Paseo Adelanto and at the Aliso Viejo substation, provides 24-hour contract law
enforcement services to the City. At the present time, the OCSD maintains a ratio of 1 sworn
office for each 1,100 residents in the City. A total of 28 OCSD personnel are assigned to the City
of San Juan Capistrano, including one lieutenant, four sergeants, two investigators, 21 deputies,
and two community service officers. The City's staffing level is based on response times and
crime rates determined to be adequate for the City. Law enforcement in the City is provided by
units that patrol San Juan Capistrano during designated shifts. In 2010, the OCSD emergency
response time for Priority 1 calls in San Juan Capistrano was 3.47 minutes. The emergency
response times for Priority 2 calls was 6.76 minutes.
Service provided includes staffing for calls for service, preventive patrol, traffic enforcement,
general and traffic investigation, and specialized enforcement, which includes a Red Light
Camera system deputy, school resource office, motor deputies, and a regional directed
enforcement deputy. Sheriffs regional and departmental services are also supplied to the City,
which include homicide, sex, and economic crime investigations. Special weapons and tactics
(SWAT), Hostage Negotiations, and Reserve supplement, and many other services are also
available to the City from OCSD. The department maintains mutual aid agreements with
surrounding contracted Sheriffs cities. On major planned or emergency events, outlying cities
will supply manpower and resources to assist. Depending on the event, reimbursement may be
necessitated to the contributing agency. City, County, and State mutual aid agreements exist for
a variety of situations.
The City expands police protection service consistent with community needs and provides an
adequate level of service based on demand (General Plan Public Services & Utilities Goal 1,
Policy 1.1, and Policy 1.2). The on-going operations of the OCSD is funded primarily from the
City's General Fund, which receives revenue from property taxes, transit taxes, fees, and other
sources. Typically, the City would use a part of this additional revenue to increase police
staffing, as needed. In addition to the operational funding for police services, the City requires
each development to pay development impact fees for police services prior to construction.
These fees are used to fund the direct impact on increased demand for police facilities and
equipment.
The proposed project would not result in a need to construct a new policy station or physically
alter an existing police station. As previously stated, the development impact fees for capital
PAGB97
CHURCH OF JESUS CHRIST OF LA TIER DAY SAINTS MEETINGHOUSE PROJECT
improvements and infrastructure costs would be collected even though a new facility would not
be created. The fair share funds are intended to pay for project financial impacts on police
protection service. The proposed project's environmental impact to police service is considered
less than significant.
Schools
The provision of education and school facilities in the City is the responsibility of the Capistrano
Unified School District (CUSD), which is the second largest school district in Orange County,
encompassing 195 square miles. The CUSD includes all or part of the following cities and
communities: Aliso Viejo, Dana Point, Laguna Niguel, Mission Viejo, Rancho Santa Margarita,
San Clemente, San Juan Capistrano, Coto de Caza, Dove Canyon, Ladera Ranch, Las Flores, and
Wagon Wheel. The CUSD currently (2017) operates 33 K-6 schools, two K-8 schools, 10 middle
schools, seven high schools, two alternative education programs, and two exceptional needs
facilities. Elementary schools located in the City of San Juan Capistrano, include Del Obispo,
Harold Ambuehl , Kinoshita, and San Juan Elementary Schools. Secondary schools in the City
include Marco Forster Middle School, J. Serra, California Preparatory Academy, and San Juan
Hills High School. The CUSD is governed by a seven-member Board of Trustees.
Since 1991, the CUSD's student population has grown by approximately 29,000 students; the
CUSD has opened 31 new schools in the 17-year period since 1991. The most recent addition to
the CUSD's facilities is San Juan Hills High School, which was complete d and op e n e d in
September 2007. As of 2016-2017, the CUSD accommodated a total of 53,613 students, which
accounted for approximately 11 percent of the total public school enrollment in the County.
According to the CUSD, approximately 60 percent of the students attending schools in the CUSD
are housed in permanent school facilities; the remaining 40 percent of the students are housed
in interim facilities.
The average cost of school facilities required to house students generated from new
development is estimated to be $53,041.33 per student based on the 2010 School Facilities
Needs Analysis prepared by the CUSD. The CUSD recently adopted a Facilities Master Plan that
addresses long-term future needs at each of the District's 56 school campuses. That plan is
currently under review by the District and is being updated in order to address current school
facility's needs. While the CUSD is currently updating enrollment data, enrollment continues to
exceed District capacity.
Funding for new school construction is provided through State and local revenue sources. The
CUSD does levy school fees on new development in accordance with SB 50. The District
currently assesses a Level I developer school fees on new development. However, the developer
of the Whispering Hills Estates CDP entered into a Mitigation Agreement at the time the CDP
was approved in 2004. As a result, impacts to school facilities caused by development within
the Whispering Hills Estates CDP are mitigated under the terms of that mitigation agreement in
lieu of the State statutory developer school fees.
The proposed project would not result in a need to construct a new school or physically alter an
existing school. The proposed project would be subject to the mitigation agreement for the
Whispering Hills Estates CDP, which would mitigate the financial impacts of the proposed
project on school facilities. The proposed project's environmental impact to schools is
considered less than significant.

Parks
Parks and recreation facilities are provided by the City of San Juan Capistrano. City park
facilities are operated and maintained by the Community Services Department. The City's parks
system consists of existing public and private parks. To ensure that adequate parks and
recreational opportunities are available to the residents in San Juan Capistrano, the City has
established a parkland standard of five acres for each 1,000 residents, consistent with the
Quimby Act.
The project would result in the construction of church facilities on the project site. The project
would not result in direct population growth ea. The project does not propose to construct any
park land within the project site. However, the project does include a multi-purpose room
which is intended to be used for private recreational purposes (basketball, volleyball, and
dining purposes).
The proposed project would not result in a need to construct a new park or physically alter an
existing park. The developer will be required to pay park dedication fees, which would serve as
an adequate financial offset for park demand. The proposed project's environmental impact to
parks is considered less than significant.
Other Public Facilities
The proposed project would not result in a need for other public facilities that are not
addressed above, or in Section XVIII Utilities and Service Systems. Implementation of the
proposed project would have no impact relative to this issue.

Background
A Traffic Impact Study (January 2017) was prepared by KOA Corporation for the proposed
project. Additionally, an Updated Traffic Impacts Assessment (April 2017) was completed in
order to update the results of the previous analysis as a result of lane configuration changes at
the intersection of Stallion Ridge and La Plata Avenue. An additional through lane was added for
southbound traffic. The Updated Traffic Impacts Assessment includes traffic analysis and
queuing analysis of this intersection. The following is a summary of the reports, which are
contained in Appendix E.
Study intersections and roadway links were identified as those that may potentially be
impacted by the proposed project. The intersection capacity analysis of potential project traffic
impacts examined weekday conditions during the morning (AM -7:00AM to 9:00AM) and
afternoon (PM -4:00 PM to 6:00 PM) peak hours and weekend conditions during the midday
(MD-6:30AM to 5:00PM) peak hours for a total of nine intersections.
The mid-block roadway link analysis includes a total of eight segments. The City of San Juan
Capistrano General Plan Circulation Element has identified several "Hot Spot" locations where
level of service (LOS) E is considered acceptable with a Hot Spot designation of "Limited Space",
"Traffic Operations", or "School".
The following 10 study intersections and eight roadway segments have been included in the
analysis:

Traffic Analysis Scenarios
The study intersections were evaluated for the following four scenarios:
• Scenario 1: Existing Conditions -LOS and daily traffic volumes based on existing peak
hour volumes and existing intersection configurations.
• Scenario 2: Existing Plus Project -Existing traffic volumes plus trips from the
proposed project.
• Scenario 3: Near-Term (2017) Conditions -This scenario includes cumulative
volumes.
• Scenario 4: Near-Term (201 7 ) Plus Project Conditions -This scenario includes
cumulative volumes plus the trips from the proposed project.
Existing Roadway Network
The following is a detailed description of the roadways that could be affected by the project:
• 1-5 Freeway is located approximately two miles west of the project site (four-mile
driving distance). The 1-5 Ortega interchange has recently been reconfigured to include
a realignment of the intersection of Del Obispo Street and Ortega Highway and
reconfiguration of the 1-5 NB Ramps.
• Ortega Highway is a primary arterial (four-lane divided roadway) that extends in the
east-west direction, north of the project site. On-street parking is prohibited on both
PAGB102 =:J
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
sides of this roadway within the study area, between the I-5 freeway and La Pata
Avenue. The posted speed limit on Ortega Highway 12 35 miles per hour (mph) from I-5
to Rancho Viejo Road, 40 mph from Rancho Viejo Road to Avenida Victoria/Via Cuartel,
and 45 mph from Avenida Victoria/Via Cuartel to La Plata Avenue. The study
intersections of Ortega Highway at I-5 SB Ramps, I-5 NB Ramps, Rancho Viejo Road, La
Novia Avenue, and La Plata Avenue are controlled by traffic signals.
• Rancho Viejo Road is designated as a commuter collector south of Ortega Highway,
and as a secondary arterial north of Ortega Highway. However, it is constructed as a
primary arterial (four-lane, divided roadway) that extends in the north-south direction.
Parking is not permitted on either side of this roadway. The posted speed limit on
Rancho Viejo Road is 30 mph.
• La Novia Avenue is a primary arterial (four-lane, divided roadway) between Ortega
Highway and San Juan Creek Road. On-street parking is permitted along segments of the
east side of La Novia Avenue, south of Ortega Highway. The posted speed limit on La
Novia Avenue is 35 mph.
• La Pata Avenue is designated as a primary arterial (four-lane, divided roadway) south
of Ortega Highway, and as a major arterial north of Ortega Highway. Parking is not
permitted on either side of this roadway. The posted speed limit on La Pata Avenue is
55 mph.
• Vista Montana is designated as a commuter street. However, it is constructed as a
secondary arterial (four-lane, divided roadway) that extends in the west direction from
La Pata Avenue and terminates at San Juan Hills High School. Parking is not permitted
on either side of this roadway. The posted speed limit on Vista Montana is 40 mph. the
proposed project will provide a right-in and right-out only driveway along this roadway.
• School Access Road is a two-lane roadway that extends from La Pata Avenue to Vista
Montana, along the west side of the project site. It provides access to the project site and
the San Juan Hills High School with a SB right-turn lane at La Pata Avenue. This roadway
is stop-controlled at Vista Montana. The proposed project will provide two full access
driveways along this roadway. There are no SB left-turn movements permitted from
School Access Road onto Vista Montana during the morning and afternoon hour due to
the high eastbound and westbound school traffic.
Intersection Capacity Utilization (ICU) Methodology for Intersections
The Intersection Capacity Utilization (ICU) methodology has been used for the analysis and
evaluation of traffic capacity at signalized intersections. The ICU method estimates the volume-
to-capacity (V /C) relationship to an intersection based on the individual V /C ratios for key
conflicting traffic movements. The ICU numerical values represent the percent signal green
time, and thus capacity, required by traffic. Using the ICU procedures, a determination can be
made of the operating characteristics of an intersection in terms of LOS for different levels of
traffic volumes and other variables, such as critical signal phases and the number and type of
traffic lanes. The Traffix computer software has been used for the analysis. A lane capacity of
1,600 vehicles per lane (vpl) with a five percent yellow clearance per cycle was used in the
analysis.
The operational performance of the roadway network is commonly described with the term
LOS. LOS is a qualitative description of operating conditions, ranging from LOS A (free-flow
traffic conditions with little or no delay) to LOS F (oversaturated conditions where traffic flows
exceed design capacity, resulting in long queues and delays). Table 18 summarizes the
relationship between LOS and ICU V /C ratio for intersections.
[ PAGE103 :J
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
According to the City of San Juan Capistrano criteria, LOS "D" is the mm1mum acceptable
condition that should be maintained during the morning and evening peak hours. LOS "E" is the
minimum acceptable conditions at locations identified with a "Hot Spot" designation.
Table 18: LOS as a Function of JCU Values for Intersections
LOS Description (for Signalized Intersections) RangeofiCU
Values
A Operations with very low delay occurring with favorable traffic signal 0.00-0.600 progression and/or short cycle lengths.
B Operations with low delay occurring with good progression and/or short 0.601-0.700 cycle lengths.
c Operations with average delays resulting from fair progression and/or longer 0. 701-0.800 cycle lengths. Individual cycle failures begin to appear.
Operations with longer delays due to a combination of unfavorable
D progression, long cycle lengths, or high V /C ratios. Many vehicles stop and 0.801-0.900
individual cycle failures are noticeable.
Operations with high delay values indicating poor progression, and long cycle
E lengths. Individual cycle failures are frequent occurrences. This is considered 0.901-1.000
to be the limit of acceptable delay.
F Operations with delays unacceptable to most drivers occurring due to over-1.001 and up saturation, poor progression, or very long cycle lengths.
SOURCE: KOA CORPORATION, 2017.
Highway Capacity Manual (HCM) Methodology for Intersections
In addition to the ICU method, all signalized and unsignalized intersections are required to be
analyzed using the Highway Capacity Manual (HCM) method. HCM is also the methodology
Caltrans recommends using for the State Transportation Facilities. The analysis results include
average vehicle delays for lanes/approaches and expected vehicle queue lengths. The LOS is
based on the estimated vehicular delay in seconds per vehicle for the control turning movement
or approach of an intersection. Total delay is defined as the time elapsed between when a
vehicle stops at the end of a queue and when the vehicle departs from the stop line.
Traffic software performs computerized transportation analyses that model (replicate) travel
behavior for measured or projected traffic volumes. A lane capacity of 1,600 vpl with a lost time
of four-second per signal phase was used in the analysis, which is consistent with current
yellow-time standards. A description of the different LOS and their corresponding HCM average
vehicul a r delays is shown in Table 19.

Daily Volume-to-Capacity (V /C) Ratio Methodology for Roadway Links
All mid-block roadway s egments are required to be evaluated us ing the daily V fC analysis
method. The daily V fC relationship is used to estimate the LOW of the roadway segments with
the volume based on the 24-hour traffic volume and the roadway classification. The roadway
link capacity in vehicles per day (vpd) of each street classification according to the Orange
County Master Plan of Arterial Highways (MPAH) is presented in Table 20 with corresponding
LOS and V fC ratios. The Peak Hour Link Capacity is based on 10 percent of the daily link
capacity in vehicles per hour (vph).
According to the City of San Juan Capistrano criteria, LOS "D" is the m1mmum link LOS
performance goal for primary, secondary, and limited secondary arterials. LOS "C" is the
performance goal for local residential arterials. LOS "E" is the minimum acceptable conditions
at locations identified with a "Hot Spot" designation.

Peak Hour Volume-to-Capacity (V /C) Ratio Methodology for Roadway Links
In addition to the Daily V /C method of analysis, the roadway segments that are impacted
utilizing the Daily V /C method are required to be analyzed using the Peak Hour V /C method to
confirm the project's impact. The peak hour operating conditions for the key impacted roadway
links have been evaluated according to the peak hour capacities of the roadway. If the daily
roadway V /C ratio results in adverse service levels, a peak hour link analysis is conducted to
determine if the roadway operates at satisfactory levels in the critical AM and PM peak hours.
Intersection Performance Impact Criteria
The City of San Juan Capistrano defines a significant traffic impact in the Administrative Policy
310 (City of San Juan Capistrano, April 4, 1998). According to City policy, a significant "project
impact" is identified as an increase in the ICU value, due to project-related traffic, of 0.010 or
more when the "Plus Project" conditions LOS is E or F. No significant project impacts are
deemed to occur at LOS A, B, C, or D.
For HCM analysis method, the City policy specifies a significant "project impact" as an increase
in the HCM value, due to project-related traffic, of 1.0 second delay per vehicle or more when
the "Plus Project" conditions LOS is F. No significant project impacts are deemed to occur at LOS
A, 8, C, D, orE, as LOS E is acceptable at "Hot Spot" locations.
For "Hot Spot" intersection locations, LOS E is acceptable. A significant "project impact" is
identified as an increase in the ICU value, due to proj e ct-related traffic, of 0.010 or more when
the "Plus Project" conditions LOS is F. No significant project impacts are deemed to occur at LOS
A, 8, C, D, orE, as LOSE is acceptable at "Hot Spot" locations.
For HCM analysis method at "Hot Spot" locations, a significant "project impact" as an increase in
the HCM value, due to project-related traffic, of 1.0 second delay per vehicle or more when the
"Plus Project" conditions LOS is F. No significant project impacts are deemed to occur at LOS A,
8, C, D, orE, as LOS E is acceptable at "Hot Spot" locations.
Roadway Link Performance Impact Criteria
According to City policy for primary and secondary arterials, a significant "project impact" is
identified as an increase in the V /C ratio, due to project-related traffic, of 0.010 or more when
the "Plus Project" conditions LOS is E or G. No significant project impacts are deemed to occur at
LOS A, B, C, or D.
For local residential arterials where LOS "C" is the performance goal, a significant "project
impact" is identified as an increase in the V /C ratio, due to project-related traffic, of 0.010 or
more when the "Plus Project" conditions LOS is D, E or F. No significant project imp ac ts are
deemed to occur at LOS A, 8, or C.
For "Hot Spot" roadway segment locations, LOS E is acceptable. A significant "project impact" is
identified as an increase in the V fC ratio, due to project-related traffic, of 0.010 or more when
the "Plus Project" conditions LOS is F. No significant project impacts are deemed to occur at LOS
A, 8, C, D, orE, as LOS E is acceptable at "Hot Spot" locations.

The estimation of geographic distribution for trips for the proposed project uses considered
several factors. The primary factors affecting the trip distribution for the project are the nature
of the uses; existing traffic patterns; the geographic location of the site and its proximity to
freeways and major travel routes; and the relative distribution of the population from which
prospective employees and visitors of the project would expect to be drawn. The overall project
directional trip distribution was determined based on these factors.
There are not SB left-turn movements permitted from School Access Road onto Vista Montana
during the morning and afternoon hours due to the high eastbound and westbound school
traffic. Therefore, project trips are assigned to make a SB right-turn from School Access Road to
travel westbound on Vista Montana to make a left-turn at Via Pamplona to return to Vista
Montana and travel towards La Plata Avenue. The trip distribution redirection only applies to
the AM project trips and is reflected in the Existing Plus Project and Near-Term Plus Project
conditions.
Existing Plus Project-Intersection Capacity Utilization (ICU) Analysis
Table 26 summarizes the intersection peak hour LOS results at the key study intersections
based on the ICU method. The ICU values of Column (1) in Table 26 present a summary of
existing AM, PM, and Weekend MD (WE) peak hour traffic conditions. Column (2) lists Existing
Plus Project traffic conditions based on existing intersection geometry. Column (3) lists Near-
Term (2017) Plus Project traffic conditions based on existing intersection geometry. Column ( 4)
shows the change in ICU value due to the addition of project traffic and indicates whether the
proposed project will result in a project impact based on the LOS standards and significant
impact criteria defined in this section.
Table 26 summarizes the results of the ICU analysis for the Existing Plus Project and Near-Term
(2017) Plus Project conditions. As shown in Table 26, all of the study intersections are
projected to operate at acceptable service levels for the Existing Plus Project condition. This
table shows that the project is not expected to result in significant project impacts at any of the
study intersections for the Existing Plus Project condition, based on the ICU analysis method.
Near-Term (2017) Plus Project-Intersection Capacity Utilization (ICU) Analysis
As shown in Table 26, all the study intersections are projected to operate at acceptable service
levels for the Near-Term (2017) Plus Project condition. This table shows that the project is not
expected to result in significant project impacts at any of the study intersections for the Near-
Term (2017) Plus Project condition, based on the JCU analysis method.

As part of the Updated Traffic Impacts Assessment, queuing analysis for all left turn movements
at the La Pata Avenue at Stallion Ridge/Vista Montana intersection was conducted for the
Existing and Existing Plus Project conditions. Table 30 below summarizes the 95th percentile
queuing lengths for each of the left turn movements during the AM and PM peak hours.
The eastbound left turn movement of this study intersection has two left turn lanes with the
inside lane having a bay length of approximately 175 feet, and the outside lane having a length
of approximately 380 feet. The eastbound left turn movement has a 223-foot calculated queue
length, based on the analysis, which is shown to exceed the capacity. Although the queue length
PAGB114 ~
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
is calculated at 223 feet, the inside lane is approximately 235 feet in overall length, including
the taper length. Therefore, the calculated left turn queue length of 223 feet will not have
significant impacts to this intersection.

Conclusion
According to the January 2017 traffic study, all intersections and roadway links would operate
at acceptable levels in the Existing Plus Project and Near-Term (2017) Plus Project conditions.
Additionally, according to the Updated Traffic Impacts Assessment, the La Pata Avenue at Stallion
Ridge/Vista Montana would continue to operate at acceptable levels in the Existing Plus Project
and Near-Term (2017) Plus Project conditions. Therefore, impacts would be considered less
than significant.
Response c): The proposed project does not include airport or airstrip facilities and is not
located adjacent to an airport or airstrip. The closest airstrip is the John Wayne Airport
approximately 18.5 miles northwest of the project site. According to the Orange County ALUC
Land Use Plan for John Wayne Airport, the project site is not located within any of the safety
zones. The proposed project would not 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.
Implementation of proposed project would have no impact relative to this topic.
Responses d-e): No site circulation or access issues have been identified that would cause a
traffic safety problem/hazard or any unusual traffic congestion or delay. Access to the project
site would be provided by one stop-controlled right-in/right-out only access driveway on Vista
Montana and two stop-controlled full access driveways on School Access Road. The proposed
access driveway along Vista Montana is proposed to be aligned with Via Granada on the south
side and located approximately 425 feet east of La Pata Avenue. Based on the project site plan,
this driveway will provide sufficient drive isle clearance between Vista Montana and the
parking lot to allow for any potential queuing of vehicles to occur on-site. The two stop-
controlled access driveways along School Access Road will provide adequate access to the
project site.
Based on the site plan, the parking lot layout will provide 25-foot wide two-way drive isles
throughout the parking lot for adequate access to parking spaces. Pedestrian access from the
L PAGE115
INITIAL STUDY CHURCH OF jESUS CHRIST OF LA 'ITER DAY SAINTS MEETINGHOUSE PROJECT
parking lot is provided by a pedestrian walkway that leads to the building entrance. Pedestrian
sidewalks are also provided surrounding the building and access from Vista Montana.
The analysis indicates that all intersections and roadway links would operate at acceptable
levels in the Existing Plus Project and Near-Term (2017) Plus Project conditions. Therefore,
impacts associated with design features and emergency access would be considered less than
significant.
Response t): The Circulation Element of the City of San Juan Capistrano General Plan includes
the following policies that are relevant to alternative transportation:
• Policy 2.1: Encourage the increased use and expansion of public transportation
opportunities.
• Policy 2.2: Promote new employment-producing development in areas where public
transit is convenient and desirable.
• Policy 2.3: Encourage the provision of additional regional public transportation
services and support facilities, such as park-and-ride lots.
• Policy 3.1: Provide and maintain an extensive trails network that supports bicycles,
pedestrians, and horses and is coordinated with those networks of adjacent
jurisdictions.
The proposed project does not conflict with any of the above listed policies from the General
Plan Circulation Element. The proposed project would not generate a significant increase in
traffic in the area compared to the existing and it would not decrease levels of service to
unacceptable levels. In addition, the proposed project would not change the design of any
existing pedestrian or bicycle facilities or create any new safety problems in the area. The
proposed project will add a small amount of both pedestrians and bicyclists who will utilize
both existing and planned facilities connecting the project site with the community at large.
The proposed project would not interfere with any existing bus routes and would not remove
or relocate any existing bus stops. The proposed project also would not conflict with any transit
plans or goals of the City of San Juan Capistrano and, based on the size of the project, it would be
expected to generate only limited transit ridership. The project would be expected to provide a
minimal amount of additional ridership for the local bus company, the Orange County
Transportation Authority.
Implementation of the proposed project would have a less than significant impact relative to
this topic.

subdivision (c) of Public Resources Code Section
5024.1, the lead agency shall consider the
significance of the resources to a California Native
American trib e.
Responses to Checklist Questions
Responses a-b): The City has initiated tribal consultation in accordance with Assembly Bill
(AB) 52. The City requested a list of tribes that may be interested in the proposed project from
the Native American Heritage Commission (NAHC). On January 11, 2017, the NAHC provided a
list of 22 tribes. In letters dated January 11, 2017, City of San Juan Capistrano sent tribal
consultation letters to all 22 of the tribes. In the letters, the City provided the tribes with
information regarding the proposed project. The City requested that the tribes supply any
information they might have concerning prehistoric sites or traditional use areas within the
project site. The only tribe that has responded to the tribal consultation letters to date is the
}uanefio Band of Mission Indians Acjachemen Nation. In February 2017, the Juanefio Band of
Mission Indians Acjachemen Nation responded to the City's consultation letter and requested
that a mitigation measure be included in the document in order to ensure that the Juanefio Band
of Mission Indians Acjachemen Nation is consulted during construction in the event of a
discovery. This measure is included as Mitigation Measure Cul-3 .
Based on previous cultural evaluations and consultations, and the mass grading activities that
have occurred on the project site, there is a low potential for the discovery of prehistoric,
ethnohistoric, or historic archaeological sites that may meet the definition of Tribal Cultural
Resources (TCRs). Although no TCRs have been documented on the project site, the project is in
a region where significant cultural resources have been recorded and there remains a potential
that undocumented archaeological resources that may meet the TCR definition could be
unearthed or otherwise discovered during ground-disturbing and construction activities.
Examples of significant archaeological discoveries that may meet the TCR definition would
include villages and cemeteries. Due to the possible presence of undocumented TCRs within the
project site, construction-related impacts on tribal cultural resources would be potentially
significant. Implementation of the following mitigation measures would require appropriate
steps to preserve and/or document any previously undiscovered resources that may be
encountered during construction activities, including human remains. Implementation of these
measures would reduce any potential impact to a less than significant level.

Responses to Checklist Questions
Responses a), b) and e): The City of San Juan Capistrano Utilities Department currently
provides water and wastewater services within the City. The City's Utilities Department
operates and maintains a sanitary sewer collection and conveyance system that includes
approximately 120 miles of sewers, which range in sizes up to 27 inches in diameter. In
addition, the City also operates and maintains two lift stations. Existing sewer facilities in the
vicinity of the project site include a sanitary sewer main in Vista Montana and La Pata Avenue.
In January 2004, the San Juan Capistrano Public Works Department completed the Sanitary
Sewer System Master Plan and Rehabilitation Program Report, which was adopted by the City
Council on November 16, 2004. The Master Plan provided a rehabilitation program for the
City's sanitary sewer system that dates back to the 1920s. This program was combined with the
City's existing rehabilitation program and in conjunction with the City's ongoing sewer cleaning
and videotaping, and helps to fulfill State and federal requirement to properly operate and
maintain the collection system and ensure that hydraulic capacities are adequate to
accommodate sewage generated within the system and to prevent system overflows. The
PAGE 119
CHURCH OF JESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
Master Plan also included the projected operational and capital costs associated with the
treatment and outfall through the South Orange County Wastewater Authority (SOCWA).
San Juan Capistrano is one of the member-agencies that owns capacity in the SOCWA.
Wastewater collected in the City's collection system is conveyed to SOCWA's Jay B. Latham
Regional Treat ment Plant (JBLRTP) located at 34156 Del Obispo Street in the City of Dana Point.
SOCWA serves a 22-square mile area in south Orange County, including the Cities of Aliso Viejo,
Laguna Beach, Lake Forest, Laguna Woods, San Juan Capistrano, Laguna Niguel, San Clemente,
Santa Margarita, Mission Viejo, Dana Point and Laguna Hills, as well as unincorporated
territories within the 22-square mile area. In addition, SOCWA also operates the San Juan Creek
Ocean Outfall, which discharges secondary-treated wastewater from the plant into the Pacific
Ocean. The City is one of four member agencies that own treatment capacity in the Treatment
Plant. The other member agencies are Moulton Niguel Water District (MNWD), Santa Margarita
Water District (SMWD), and the South Coast Water District (SCWD). SOCWA also operates the
San Juan Creek Ocean Outfall , which discharges treated wastewater into the Pacific Ocean for
disposal. The outfall is under the jurisdiction of the San Diego Regional Board.
The Jay B. Latham Regional Treatment Plant (JBLRTP) is a conventional activated sludge
wastewater treatment with secondary treatment design liquid treatment and solids handling
capacities of 13.0 million gallons per day (mgd) and 18.5 mgd, respectively. The City of San Juan
Capistrano owns 4.0 mgd of the liquids treatment capacity (30. 77 percent) and 5.55 mgd of th e
solids handling capacity (30 percent) of the treatment plant.
Sewer mains are located under existing streets within the vicinity of the project site. These
sewer mains collect and convey raw sewage generated by the existing single-family residential
development and by San Juan Hills High School to the JBLRTP. Sewage flows are conveyed in the
City's collection system from this location to facilities in Camino Capistrano and along Trabuco
and San Juan Creeks before entering the JBLRTP in Dana Point, where the raw sewage is treated
and the effluent discharged from an ocean outfall into the Pacific Ocean.
Article 5, Section 9-4.523 of Title 9 (Land Use) of the City's Municipal Code addresses sanitary
sewers and includes sewage generation rates for a variety of land uses. Table 4-2 in Section
9-4.523 reflects average daily flow rates for uses other than residential. According to Table 4-2,
assembly hall uses generate one gallon per day per seat. The project would include 292 fixed
seats and pews. Based on the generation rate of 1 gallons per day per seat, the proposed
292-seat church development would generate an estimated 292 gallons of raw sewage each
day.
The raw sewage generated by the proposed project would be conveyed from the site via a series
of four-to eight-inch sewer pipes, ultimately connecting to an existing city sewer main in Vista
Montana. Private sewer clean outs would also be constructed, pursuant to City standards.
The project applicant will be required to prepare and submit a sewer study that reflects the
design standards prescribed by the City for both laterals and main line sewers, if determined
necessary as a result of the sewer study. In addition, all laterals extended to the existing sewer
main from the project site would be designed in accordance with the Uniform Plumbing Code.
As a result, project implementation will not result in significant impacts; no mitigation
measures are required.
The City has established that there is adequate capacity at the WWTRF to serve build-out of
anticipated residential land in the city, and the distribution system operates at acceptable levels
[ PAGE 120
CHURCH OF jESUS CHRIST OF LA TIER DAY SAINTS MEETINGHOUSE PROjECT JNJTIALSrtJDY
and has been designed to accommodate expansions and service extensions. The proposed
project would place a church facility on a site that was originally planned for residential
development. The wastewater generated would be less then what would be generated if the
project were developed under residential uses. There is capacity at the WWTRF to serve the
proposed project. The project applicant would be required to pay applicable connection fees to
offset any financial impacts. There would not be a need to expand or build a new treatment
facility. Implementation of the proposed project would have a less than significant impact.
Response c): Development of the project site would place impervious surfaces on the
approximately 4.54-acre project site. Development of the project site would potentially increase
local runoff, and would introduce constituents into storm water that are typically associated
with urban runoff. These constituents include heavy metals (such as lead, zinc, and copper) and
petroleum hydrocarbons. BMPs will be applied to the proposed site development to limit the
concentrations of these constituents in any site runoff that is discharged into downstream
facilities to acceptable levels.
The project would be designed and constructed with an on-site storm drainage bio-retention
basin. The bio-retention basin would be located in the northern portion of the project site. The
basin is designed to be five feet deep with two feet of sand, three inches of coarse sand, two feet
of gravel, and one foot of free board. The basin area would account for a total surface area of
3,603 square feet. The basin is engineered to account for on-site storm drainage flows.
The construction of the stormwater conveyance and detention system would ensure that the
project is consistent with all applicable plans and regulations related to stormwater conveyance
and detention as required by the city, and would ensure that offsite, or onsite flooding does not
occur during storm events.
All of the storm drainage facilities required for the proposed project would be located on the
project site. As such, there is no potential for the project to result in environmental impacts
associated with the construction of off-site drainage facilities. The environmental impacts
associated with the construction of onsite drainage facilities fall within the project "footprint"
and have been addressed throughout this environmental document. Implementation of the
proposed project would have a less than significant impact.
Response d): The City of San Juan Capistrano Utilities Department provides water services to
the project site. The Utilities Department derives its domestic water from three sources: (1) 45
percent is purchased from the Metropolitan Water District of Southern California (MWD) and
consists of water from the Colorado River via the Colorado River Aqueduct and Northern
California water via the State Water Project; (2) approximately 44 percent of the City's water
supply is produced by its Groundwater Recover Plant; and (3) the remaining 11 percent is
obtained from local groundwater wells located within the City. Domestic water is provided
within the City's system within six distinct zones defined by reservoirs, and 27 sub-zones
served through pressure regulating stations and hydropneumatic systems.
San Juan Capistrano itself does not have any surface water supplies. Indirectly the City gets
surface water from the imported water system. All of the City's locally produced domestic water
supply is from groundwater and, when needed, imported water from the State Water Project
system (surface) and/or Colorado River (surface). Imported water is supplied to the City
through connections from the Joint Regional Water Supply System's (formerly the Tri-Cities
Municipal Water District) Eastern Transmission Main, and the South County Pipeline. The
[ PAGR121
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
remainder is from local groundwater. Supply through the Eastern Transmission Main is
conveyed to the City at the Master Meter (CM-10), which provides the majority of the imported
water supply to the City at a hydraulic grade elevation (HGE) varying from 450 to 475 feet
above mean sea level (amsl). The City is allowed to take up to 15 cubic feet per second (cfs) at
the Master Meter connection. Imported water from the South County Pipeline is conveyed
through the SC-04 Turnout connection. The City's current capacity through the SC-04
connection is 4.9 cfs at the HGE of 800 feet amsl. The City has an option to obtain additional
capacity, up to a total of 10.0 cfs in the future.
The City of San Juan Capistrano adopted a Domestic Water Master Plan (DWMP) and
Non-Domestic/Recycled Water Master Plan Updated to address water resources in the City. The
Groundwater Recovery Plant (GWRP) extracts water that is high in minerals (e.g., iron,
manganese, and total dissolved solids) and treats the water to make it suitable for potable
water uses. The GWRP facilities consist of six wells located along the San Juan Creek as well as a
treatment facility located in the City's municipal complex. The reverse osmosis treatment
facility sequesters and removes the iron and manganese in addition to high concentrations of
total dissol ved solids; chlorine and ammonia are added to the finished water, which
supplements the potable water supply. This facility has an existing treatment capacity of 5.14
million gallons per day (mgd).
The City provides domestic water service within a n area that encompasses approximately 14.4
square miles (i.e., 9,2 00 acres), mostly within its corporate boundaries. The existing population
in the City's water service area is about 36,000. The current water use average day domestic
water demand for the City of San Juan Capistrano service area is approximately 8.4 mgd, with a
maximum day domestic demand of approximately 16.0 mgd. Ultimate domestic water demand
for the City's service area at buildout (i.e., 2020) is estimated to be about 9.14 mgd for an
average day and 17.3 6 mgd for the maximum day demand.
The proposed project includes development of a 16,558-square-foot Meetinghouse/Cultural
Hall building and chapel with 292 fixed seats and pews on the 4.54-acre site. The "Average Day
Demands" established by the City of San Juan Capistrano's Standard Specifications for the
Construction of Domestic Water and Recycled Water Facilities (2006) were used to calculate
estimated water demand for the proposed project. A demand factor of 935 gallons per day
(gpd) for Public/Institutional was used. Total daily demand is estimated to be 4,244.9 gpd. The
additional water demand (4,244.9 gpd) would not exceed the City's available water supply. The
City's water treatment and conveyance infrastructure is adequate to serve existing demand, in
addition to the demand created by the proposed project. Implementation of the proposed
project would have a less than significant impact.
Responses f), g): The City of San Juan Capistrano contracts with CR&R, a private solid waste
hauler, to collect and dispose of the solid waste/refuse generated in the City. Solid waste/refuse
collected in the City by CR&R is transported to one of the Class III (i.e., acceptance of municipal
solid waste) operated and maintained by the County of Orange OC Waste & Recycling (OCW &R),
formerly called Integrated Waste Management Department (IWMD). The OCW&R is responsible
for providing sanitary landfill capacity to the City of San Juan Capistrano and within the County
of Orange. At the present time, the OCW&R maintains and operates three Class III sanitary
landfills: Frank R. Bowerman Landfill, Olinda Alpha Landfill, and Prima Deshecha Landfill.
Of the three landfills currently operated by the IWMD, the closest landfill to the site, and the one
that would accept refuse generated at the site, is the Prima Deshecha Landfill, located at 32250
La Pata Avenue in the City of San Juan Capistrano. The landfill property encompasses 1,530
PAGE12-2 ]
CHURCH OF jESUS CHRIST OF LATTER DAY SAINTS MEETINGHOUSE PROJECT
acres, of which 699 acres are permitted for refuse disposal activities. The landfill was opened in
1976 and is scheduled to close in approximately 2067. The Prima Deshecha Landfill, which is
permitted to accept up to 4,000 tons of municipal solid waste per day, currently receives an
average of approximately 1,500 to 2,000 tons per day (i.e., 37.5 to 50 percent of its daily
permitted capacity). The landfill has an estimated remaining disposal capacity of 135.09 million
cubic yards.
Project construction activities would generate solid waste, including excess construction
materials and material removed during site clearing. However, the site is vacant, and
construction would not require demolition of existing structures or removal of large quantities
of waste. It is anticipated that compliance with the construction waste requirements in
CALGreen would be sufficient to minimize solid waste generation. Additionally, as required by
City Code Section 4.11.3-2, reuse, recycling and/or diversion of SO percent or more of the
construction debris will reduce the amount of construction waste materials deposited in one of
the County's sanitary landfills. As a result, construction impacts associated with the proposed
project would be less than significant.
During operation of the project, the church facility would produce solid waste that would be
collected and transferred to the landfill system. Based on a waste generation rate of 0.007
pounds per square foot per day2 and the proposed 16,558-square-foot church, the project is
expected to produce approximately 115.9 pounds per day (21.2 tons of solid waste annually).
The landfill system has sufficient permitted capacity to accommodate the project's solid waste
disposal needs in compliance with all applicable laws based on the calculated waste generation
rate. Implementation of the proposed project would have a less than significant impact
relative to this topic.

covers a broad spectrum of topics relative to the potential for the proposed project to have
environmental impacts. It was found that the proposed project would have either no impact, a
less than significant impact, or a less than significant impact with the implementation of
mitigation measures. These mitigation measures would also function to reduce the project's
contribution to cumulative impacts.
The project would increase the population and use of public services and systems; however, it
was found that there is adequate capacity to accommodate the project.
There are no significant cumulative or cumulatively considerable effects that are identified
associated with the proposed project after the implementation of all mitigation measures
presented in this Initial Study. With the implementation of all mitigation measures presented in
this Initial Study, the proposed project would have a less than significant impact relative to
this topic.
Response c): The construction phase could affect surrounding neighbors through increased air
emissions, noise, and traffic; however, the construction effects are temporary and are not
substantial. The operational phase could also affect surrounding neighbors through increased
air emissions, noise, and traffic; however, mitigation measures have been incorporated into the
proposed project that would reduce the impacts to a Jess than significant level. The proposed
project would not cause substantial adverse effects on human beings. Implementation of the
proposed project would have a less than significant impact relative to this topic.

Empire-Orange County Line are both serviced by Metrolink, while
the Amtrak Pacific Surfliner is serviced by Amtrak. OCT A does not
operate rail services.
o Please correct the local route number to Route 91. OCTA also
operates intracounty express Route 212 and Route 216, both of
which terminate at the Junipero Serra Park and Ride in San Juan
Capistrano.
Throughout the development of this project, we encourage communication with
OCTA on any matters discussed herein. If you have any questions or comments,

This comment is noted . Revisions to the Initial Study are identified below with
revision marks (u n d erline for new text, stFil~e ol:lt for deleted text). None of the
revisions identify new significant environmental impacts, nor do any of the
revisions result in substantive changes to the Initial Study. The new information
to the Initial Study is intended to merely correct and clarify the information .
Page 108 of the IS/MND notes that Orange County Transportation Authority
Local Route 99 provides local bus service generally following I-5 within the City.
While this alone is correct, additional routes provide service in the project area.
According to the comment, Routes 212 and 216 also operate within the City.
Additionally, according to the comment, the service providers for the various
transit service lines are incorrect. Page 108 of the IS/MND has been revised as
follows:

MITIGATION MONITORING AND REPORTING PROGRAM
This document is the Mitigation Monitoring and Reporting Program (MMRP) for the Church of
Jesus Christ of Latter Day Saints Meetinghouse Project (project). This MMRP has been
prepared pursuant to Section 21081.6 of the California Public Resources Code, which requires
public agencies to "adopt a reporting and monitoring program for the changes made to the
project or conditions of project approval, adopted in order to mitigate or avoid significant
effects on the environment." A MMRP is required for the proposed project because the Initial
Study j Mitigated Negative Declaration (IS/MND) has identified significant adverse impacts,
and measures have been identified to mitigate those impacts.
The numbering of the individual mitigation measures follows the numbering sequence as
found in the IS/MND.
MITIGATION MONITORING AND REPORTING PROGRAM
The MMRP, as outlined in the following table, describes mitigation timing, monitoring
responsibilities, and compliance verification responsibility for all mitigation measures
identified in the IS/MND. The City of San Juan Capistrano will be the primary agency
responsible for monitoring the mitigation measures.
The MMRP is presented in tabular form on the following pages. The components of the MMRP
are described briefly below:
• Mitigation Measures: The mitigation measures are taken from the IS/MND in the
same order that they appear in that document.
• Mitigation Timing: Identifies at which stage of the project mitigation must be
completed.
• Monitoring Responsibility: Identifies the agency that is responsible for mitigation
monitoring.
• Compliance Verification: This is a space that is available for the monitor to date and
initial when the monitoring or mitigation implementation took place.
