A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF SAN JUAN
CAPISTRANO, CALIFORNIA, APPROVING A MITIGATED NEGATIVE
DECLARATION FOR THE SUN RANCH DRAINAGE IMPROVEMENT
PROJECT (CIP 11503)
WHEREAS, the Public Works Department has prepared plans for the Sun
Ranch Drainage Improvement Project (CIP 11503) and such installation is consistent with
the recommended water facilities improvements contained in the City Council -adopted
Storm Drain Master Plan (SDMP) and,
WHEREAS, the proposed projects have been processed pursuant to Section
9-2.337, Public Improvement Plans and Outside Agency Development Review of the Land
Use Code; and,
WHEREAS, the City of San Juan Capistrano Environmental Administrator
has reviewed the initial study prepared pursuant to Section 15063 and 15064 of the CEQA
Guidelines; has determined that the project qualifies for issuance of a Mitigated Negative
Declaration (MND), has issued a Negative Declaration pursuant to Section 15070 of those
guidelines; and has caused a Notice of Negative Declaration to be posted pursuant to
Section 15072 of those guidelines. The City has otherwise complied with all applicable
f provisions of the California Environmental Quality Act (1970) and all recommended
mitigation measures have been incorporated herein; and,
WHEREAS, Draft Mitigated Negative Declaration for the City of San Juan
Capistrano Sun Ranch Drainage Improvement Project CIP (11503) was made available for
public review and comment pursuant to the CEQA Guidelines (Section 15073) for a period
of 30 days, commencing on February 3, 2012, and ending on March 5, 2012; and during
this review period, the City received no comment letters.
NOW, THEREFORE, BE IT RESOLVED that the City Council hereby makes
the following findings based on substantial evidence in the record with respect to
compliance with the provisions of the California Environmental Quality Act:
1. Pursuant to California Environmental Quality Act (CEQA) Guidelines (Section
15074), the Initial Study/Mitigated Negative Declaration (IS/MND) considers all
potentially significant environmental effects of the proposed project and is complete
and fully complies with all requirements of CEQA and the Guidelines; and,
2. While the project could result in potentially significant air quality impacts as a result
of construction -related emissions, proposed air quality mitigation measures to
address PM10 (particulate matter less than 10 microns) and PM2.5 (fine particulate
matter less than 2.5 microns) will reduce such impacts to a level of insignificance.
6-19-2012
3. A biological survey of the subject property was conducted by Glenn Lukos
Associates (GLA) in order to document the biological resources that occupy the site
and the species of plants and animals that are supported in that habitat on the site.
The survey found that the project could result in potentially significant biological
impacts as a result of construction related activities. However, the proposed
biological resource mitigation measures which manage the construction time period
and require Resource Agency permitting will reduce such impacts to a level of
insignificance.
4. The project could result in potentially significant cultural and paleontological
resources impacts as a result of construction related activities and ground
disturbance. However, the proposed cultural resource mitigation measures which
provide for archeological and paleontological monitoring will reduce such impacts to
a level of insignificance.
5. The project could result in potentially significant geological and soils impacts as a
result of construction -related activities. However, the proposed mitigation measures
which require implementation of geological/soils analysis recommendations will
reduce such impacts to a level of insignificance.
6. The project could result in potentially significant hazards and hazardous materials
impacts as a result of construction -related activities. However, the proposed
mitigation measures requiring testing and removal of any contaminated soils
encountered during . construction will reduce such impacts to a level of
insignificance.
7. The project could result in potentially significant water quality impacts as a result of
construction -related activities. However, the proposed mitigation measures requiring
preparation and implementation of a Stormwater Pollution Prevention Plan
(SWPPP) and sediment/erosion control will reduce such impacts to a level of
insignificance.
8. The project could result in potentially significant short-term construction noise
impacts. However, the proposed mitigation measures restricting construction hours,
managing the location of staging area, and managing equipment noise will reduce
such impacts to a level of insignificance.
9. The project could result in potentially significant traffic impacts. However, the
proposed mitigation measures requiring preparation and implementation of a Traffic
Control Plan and Construction Management Plan will reduce such impacts to a level
of insignificance.
NOW, THEREFORE, BE IT FURTHER RESOLVED, that the City Council of
the City of San Juan Capistrano does hereby make the following findings with respect to
General Plan consistency:
2 6-19-2012
L
1. The proposed project is consistent with the policies and objectives of the General
Plan, specifically, the Public Services Element because the proposed drain
improvements will ensure that the City maintains the ability to provide the required
flood control to the community.
2. The proposed project is consistent with the City Council adopted Storm Drain
Master Plan which identifies the improvement of the existing facilities (Project) to
provide necessary higher levels of storm drain service to existing and proposed
developments located in the surrounding area.
NOW, THEREFORE, BE IT FURTHER RESOLVED, that the City Council of
the City of San Juan Capistrano does hereby approve a Mitigated Negative Declaration
subject to the mitigation measures established by Exhibit A, Mitigation Monitoring
Reporting Program (MMRP) attached hereto and incorporated.

• Install filter materials acceptable to the City of San Juan
Capistrano at the stone drain inlets nearest to the project
site prior to the start of the wet weather season (October
15); site dewatering activities; street washing activities;
and saw cutting asphalt or concrete in order to retain any
debris flowing into the storm drain system. Filter materials
should be maintained and/or replaced as necessary to
ensure effectiveness and prevent street flooding.
• Ensure that concrete/granite supply trucks or
concrete/plaster finishing operations do not discharge
wash water into water courses, street gutters, or storm
drains.
• Direct and locate tool and equipment cleaning so that
wash water does not discharge into the street, gutters, or
storm drains.
• Create a contained and covered area on the site for
storage of bags of cement, paints, flammables, oils,
fertilizers, pesticides, or any other materials used on the
project site that have the potential for being discharged to
the storm drain system by the wind or in the event of a
material spill. No hazardous waste material should be
stored on-site.
• Gather all construction debris on a regular basis and place
them in a dumpster or other container which is emptied or
removed on a weekly basis (or other interval approved by
the City of San Juan Capistrano). When appropriate, use
tarps on the ground to collect fallen debris or splatters that
could contribute to stormwater pollution.
• Remove all dirt, gravel, refuse, and green waste from the
sidewalk, street pavement, and storm drain system
adjoining the project site. During wet weather, avoid
driving vehicles off paved areas and other outdoor work.
• As appropriate, broom sweep the street pavement
adjoining the project site on a dairy basis. Caked -on mud
or dirt should be scraped from these areas before
sweeping. At the end of each workday, the entire site
must be cleaned and secured against potential erosion,
dumping, or discharge to the street, gutter, and/or storm
drains.
• All erosion and sedimentation control measures
implemented during construction activities, as well as
construction site and materials management shall be in
strict accordance with the control standards listed in the
latest edition of the Erosion and Sediment Control Field
Manual published by the RWOB.

where necessary to within the dedicated easement width.
A minimum of one -foot of alluvial soil salvaged from
remedial grading will be placed over the entire 0.70 -acre
mitigation site.
• The channel will be constructed with riprap check dams to
control the transport of sediment within the nature
channel. Native plant material will improve the water
quality and reduce sediment transport along the mitigation
site.
• The realigned drainage channel will be restored with 0.70
acre of native riparian plant species, resulting in a net
increase in wetlands, and associated increase for
hydrologic, biogeochemical, and habitat functions.
• The mitigation site is designed to function as wetlands and
riparian habitat providing such functions as short-term
storage of surface water, dynamic storage of surface
water, groundwater recharge, nutrient cycling, retention of
particulates, removal of imported elements and
oompounds, and some provision of habitat for waterfowl,
shorebirds, passerines, and songbirds.
The compensatory mitigation project will provide the required
compensation for unavoidable temporary disturbance to 0.56
acre of aquatic resources resulting from a temporary
disturbance to ACOS, RWQCB, and CDFG jurisdiction on-site.
Approximately 0.49 acre of temporarily disturbed wetlands will
be restored at a 1.3:1 ratio, for a total of 0.70 acre of restored
