Application Summary:
Review of the initial study/mitigated negative declaration prepared for the
Stevens Creek Corridor Park Master Plan and Restoration Plan
,..
RECOMMENDATION:
The Planning Commission's role is to provide a forum for additional comments
on the initial study/mitigated negative declaration. The project has already
been defined by the City Council, through a significant public outreach and
hearing process, described below.
Staff recommends that the Planning Commission:
1) Open the public hearing and accept oral and written comments about
the initial study/mitigated negative declaration, and
2) Forward any comments to the City Council that the Planning
Commission may have.
BACKGROUND:
Creek & Park Planning. The City acquired the subject properties in five
purchases over a 25-year period. In the mid-1990s, funds were authorized for a
Master Plan, but no work was done. In 2000, City Council interest in trails
moved the corridor planning up in priority. The planning originally started with
a pl'Oposed trail along Stevens Creek, and evolved into a major creek restoration
and park renovation project with the trail as a subcomponent.
The project included a public visioning process to determine what Blackberry
Farm should become if its focus on paid/ catered picnicking were to change.
This process included three phases: solicitation of comments from stakeholder
groups, a survey of residents' opinions conducted by Godbe Research, and
distribution of 320 design kits to people interested in the design of the park.
Restoration of the creek and the adjacent riparian area emerged as an important
goal for the community.
After the public visioning process concluded, the City Council reaffirmed its
goals for the Stevens Creek Corridor project in September 2003. Between
September 2003 and the present, staff, residents and the Parks and Recreation

Commission worked to refine the Council's preferred alternative design into a
conceptual plan that would improve the habitat values of the corridor. The Santa
Clara Valley Water District joined the effort as partner in restoring steelhead
trout rearing habitat in the corridor, and the Council authorized a number of
applications for grant funding for the project.
Environmental Review. An environmental report called the Stevens Creek
Corridor Master Plan and Restoration Plan Initial Study/Mitigated Negative
Declaration (enclosed) was prepared for the preferred project. The 30-day public
review period for the environmental document began on April 28th and will
conclude May 28th. The document is available at the library and city hall and can
be down-loaded from the city's website. Interested parties have been
encouraged to comment electronically, in writing, or orally at the Planning
Commission meeting. All comments received during the public review period
will be made a part of the record for the project environmental review, and
comments will be studied and responded to prior to City Council consideration
of the document for final approval.
The Planning Commission is requested to provide this forum for public input
because of its past experience in dealing with environmental impacts of projects.
DISCUSSION:
A detailed description of the project, its environmental impacts and mitigations
will be presented by staff and the City consultants at the Commission hearing.
The Environmental Review Committee considered the documents and
recommended, on a 4-1 vote, to the City Council that a mitigated negative
declaration be adopted for the project.
The main features of the Stevens Creek Corridor Master Plan and Restoration
Plan are:
· Convert a commercial picnic facility into a neighborhood park
· Restore in-stream and riparian habitat along the creek within the 100-year
floodplain
· Enhance adjacent upland oak woodland habitat
· Construct a 5,900 foot all weather trail
· Develop a new environmental education center
· Demolition old and build new park and golf maintenance facilities
The initial study identified numerous potentially significant environmental
impacts that staff believes can be reduced to less than significant levels with the
mitigations proposed.

Biological Resources
Impact 1: The removal of structures and the removal of vegetation could impact
nesting birds, if present.
Mitigation: Vegetation, tree, bridge and building removal activities shall be
scheduled outside of the nesting season. Pre-construction surveys for raptor
nests would also be completed.
Impact 2: Construction activities can result in the abandonment of the big brown
bat maternity roost.
Mitigation: Avoidance measures would be implemented as necessary by a
qualified biologist including temporal avoidance, construction buffer zones, pre-
construction surveys, and exclusion.
Impact 3: If present, California red-legged frogs, Western pond turtles, and
Dusky-footed woodrats could be crushed by project activities.
Mitigation: Avoidance measures including pre-construction surveys, employee
education program, daily monitoring and implementing speed limits would be
used.
Impact 4: Steelhead trout could perish due to construction activities within the
creek.
Mitigation: Best Management Practices (BMPs) from the Santa Clara Valley
Water District's 200S BMP Handbook would be used to avoid impacts to
steelhead.
Impact 5: Expanded visitor use and new dog use within the project area could
impact sensitive wildlife and habitat.
Mitigation: Minimization and avoidance measures are proposed including
posting signs, patrols and citations by City Parks Service employees, volunteer
patrols and education, limiting creek use, park clean-up, screen trail, and
adaptive management.
Impact 6: Trail alignment may affect root zones of native or heritage trees.
Mitigation: Calculations for Recommended Tree Protection Zones would be
prepared by a certified arborist to reroute trail outside driplines.
Impact 7: Tree trimming or removal could violate Cupertino and California
Department of Fish and Game policies.
Mitigations:
Coast live oaks would be replaced 3:1.
- Additional tree removal permits for heritagef specimen trees if needed

- Planting activities would be consistent with the Restoration Plan and with
Guidelines and Standards for Land Use Near Streams (SCVWRPD 2OOS).
Cultural Resources
Impact 8: The project could reveal as yet unknown prehistoric or historic
archaeological resources.
Mitigation Measures:
The Project Manager shall conduct a tailgate meeting to inform all
construction personnel of the potential for exposing subsurface cultural
resources and how to recognize possible buried cultural resources.
Upon discovery of possible buried prehistoric and historic cultural resources,
work within 25-feet of the find shall be halted and the Project Manager
notified.
All excavation contracts for the project shall contain a "stop work" provision
in the vicinity of a find in the event of exposure of significant archaeological
resources.
Full-time archaeological monitoring shall be undertaken during subsurface
construction within and within a 100-ft buffer zone of SCL-71S.
Part-time archaeological monitoring is required to allow for spot-checking of
subsurface construction for areas outside of the SCL-715 boundary and 100-
foot buffer zone.
Construction methods to minimize subsurface disturbance shall be
implemented where feasible and practical.
Hazards and Hazardous Waste
Impact 9: Ground disturbance could involve soils with pesticide residue as a
result of past farming/ orchard uses.
Mitigation: Soil testing would be performed where major soil disturbance would
occur. If pesticides are detected, the appropriate contaminated material and
handling protocol would be followed.
HydrologyjWater Quality
Impact 10: Park and trail users could be subjected to health risks from heavy
flow events.
Mitigation: In the event of significant flood events, the City would close the trail
corridor and would post signs to alert users of the closure,

Impact 11: Since the exact design of the proposed environmental education
center is not known at this time, any design submitted may not be consistent
with the McClellan Ranch Master Plan.

Mitigation: The environmental education center shall be designed to fit in with
existing buildings and to be consistent with the McClellan Ranch Master Plan
