RESOLUTION NO. 91-6-18-3
CERTIFYING SUPPLEMENTAL IMPACT REPORT 90-3
GLENDALE FEDERAL AREA H)
A RESOLUTION OF THE CITY COUNCIL OF THE CITY OF SAN
JUAN CAPISTRANO, CALIFORNIA, CERTIFYING AS COMPLETE
SUPPLEMENTAL ENVIRONMENTAL IMPACT REPORT 90-3 FOR
GLENFED AREA H
WHEREAS, the applicant, Glendale Federal Development Corporation, 16601
Ventura Boulevard, Encino, California, has submitted a combined Tentative Tract Map
13726/Area Plan/Composite Development Plan, proposing to subdivide approximately 46
acres of land into 63 hillside estate lots; and,
WHEREAS, the City Council has determined that the project may have a
significant effect on the environment, has accordingly required preparation of a
supplemental environmental impact report, designated herein as EIR 90-3, by a City -
retained environmental consultant, and has otherwise carried out all requirements of the
California Environmental Quality Act (CEQA); and,
WHEREAS, in accordance with Section 15083 of the CEQA Guidelines,
numerous opportunities were provided for public participation in the environmental
review process, both before and during preparation of the supplemental environmental
impact report (SEIR). These included the following:
1. On August 29, 1990, a public scoping meeting, an optional step under
CEQA, was held to identify issues to be addressed by the SERI and was
attended by over 100 residents, many of whom submitted written
comments.
2. On December 13, 1990, a second public information meeting was held
during the 45 -day public review period to receive oral and written
comments on the Draft SEIR. The letters received have been included in
the Response to Comments section of the SEIR.
3. Direct meetings and phone contacts between staff and concerned
residents.
4. The inclusion of residents beyond the required 300 -foot boundary radius
for mailing of both Planning Commission and City Council public hearing
notices regarding the SEIR and the project; and,
WHEREAS, the final SEIR, consisting of the draft environmental impact
report, comments from the public on the draft report, and responses to those comments
prepared in accordance with Section 15088 of the CEQA Guidelines, has been reviewed
by the City Council; and,
WHEREAS, the City, through its environmental consultant, has prepared a
monitoring program to ensure that mitigation measures identified in the SEIR are
implemented; and,
RM "
WHEREAS, the City's Planning Commission has forwarded the SEIR to the City
Council recommending certification as complete; and,
WHEREAS, a public hearing has been duly advertised in the Capistrano Valley
News and held to receive and review public testimony on the SEIR and the project; and,
WHEREAS, the City Council finds, pursuant to Section 15091 of the CEQA
Guidelines, that changes or alterations have been required in or incorporated into the
project, in the form of the project design features and required mitigation measures
described herein below, which avoid or reduce to a level of insignificance each of the
significant environmental effects identified in the final SEIR. The identified impacts and
the evidence and rationale supporting the finding that each such impact will be avoided
or substantially lessened are as follows:
1. Traffic and Circulation
Impacts:
The proposed 63 -lot development will generate 760 daily trips
and contribute approximately one car per minute at peak hour
at the intersections of Camino La Ronda at La Novia and
Camino La Ronda at Paseo Establo. The project will not
overload any street segment or intersection in the vicinity of
the site.
Mitigation:
The applicant shall contribute to improvements needed to
accommodate cumulative traffic volumes through established
fees. The applicant shall prepare a construction traffic
mitigation program.
Level:
Mitigated to a level of insignificance.
2. Hydrology
Impacts:
The project will increase runoff from the western drainage
area by -_� to 3.8% during a 10-, 25-, or 100 -year flood.
Mitigation:
The applicant shall increase the capacity of the existing 5 -
foot by 6.5 -foot box culvert that crosses Camino La Ronda or
retain runoff on-site. Other mitigation measures listed on
page 58 of the SEIR include preparing an erosion control plan,
providing subdrains and terrace drains, and installing an
energy dissipater to prevent erosion in the existing La Ronda
drainage channel.
Level:
Mitigated to a level of insignificance.
3. Geology and Landform Alteration
Impacts:
Area H is located in a sedimentary basin that is susceptible to
landslides. The site is within 5 to 52 miles from 6 major
faults, however, the potential for secondary effects of
seismic activity such as liquefaction, settlement, and ground
lurching is considered low.
-2-
Mitigation:
Twenty-one mitigation measures are identified in the SEIR
beginning on page 20. All grading shall be done in accordance
with the City's Hillside Management District.
Level:
Mitigated to a level of insignificance.
4. Visual Impacts/Aesthetics
Impacts:
The views from some homes on Paseo Establo in Los Corrales
and from the hillside homes in Hidden Mountain will be
changed from open space to a view of residences and
manufactured slopes, however, the project will not obstruct
their ridgeline views. The majority of land adjacent to Los
Corrales is to remain as public open space.
Mitigation:
The site shall be contour -graded. The development shall use
colors and materials that blend in with the natural hillsides as
stated in CDP 81-2 and shall be subject to approval by the
City Planning Department.
Level:
No significant impact.
5. Vegetation and Wildlife
Impacts:
No rare or endangered species would be impacted by the
proposed development. Thirty-six acres of grassland habitat
and less than 1 acre of riparian habitat would be lost. This
contributes to the incremental decline of open space in
southern California, Construction waste water could pollute
San Juan Creek.
Mitigation: Earth moving equipment shall avoid impacts to areas outside
the grading zone. Runoff retaining structures shall remove
construction sediment and debris. Groundcover shall be used
to prevent erosion of graded areas. Native plant species will
be utilized in revegetation. Night lighting shall be controlled
and directed away from open space areas.
Level: An unavoidable adverse impact that is not considered
significant.
In addition to the above, the Executive Summary of the SEIR (Section 1.2)
covers the potential impacts of the project on Air Quality, Paleontological Resources,
and Public Services, all of which have no significant impact or are mitigated to a level of
insignificance; and,
WHEREAS, the City Council finds that the foregoing explanations of specific
project characteristics and mitigation measures constitute the "substantial evidence in
the record" required by Section 15091 of the CEQA Guidelines to support the finding that
the significant environmental effects of the project will be avoided or substantially
lessened; and,
-3-
WHEREAS, the City Council hereby finds that the alternative project location
at the terminus of Camino Las Ramblas, addressed in the environmental impact report in
Section 6.3, is not feasible because it contains richer biological resources than Glenfed
Area H and would required a greater amount of grading and landform alteration to
develop the site; and,
WHEREAS, the City Council hereby finds that the Alternative Site Plan for a
Secondary Access Road which would cross over the southern ridgeline and connect to
Lusk Areas C and D, may be feasible in that the design proposed in Attachment 2,
Exhibit C to the June 18, 1991, City Council staff report, eliminates the need to cut a
notch in the ridgeline and significantly reduces ridgeline grading, and that the road would
provide a second emergency access to Area H and an alternate route for construction
traffic.
NOW, THEREFORE, BE IT RESOLVED, that in accordance with Section 15090
of the CEQA Guidelines, the City Council of the City of San Juan Capistrano does hereby
certify that:
1. SEIR 90-3 was prepared in compliance with the California Environmental
Quality Act and is final and complete.
The information contained in the final SEIR was reviewed and considered
by the Council prior to action on the project.
BE IT FURTHER RESOLVED, that the mitigation measures and the Mitigation
Monitoring Program ( attached as Exhibit A ) are hereby adopted. Said
Monitoring Program shall ensure that the mitigation measures set forth are implemented.
PASSED, APPROVED, AND ADOPTED this
of June , 1991.
