VII. BIOLOGICAL RESOURCES
- As described previously, the
site already has been graded and the original vegetation
significantly altered. Landscaping on the perimeter of
the site provides habitat for birds. No special status
species of plants or animals occupy or use the site or
are expected to use the site.
- Eight small trees are present
on-site in the location of the proposed Spill Containment
Prevention and Countermeasure (SPCC) pond. That area is
currently a drainage control facility that was
constructed in the 1970's. The trees date from that
period. Included in these trees are four interior live
oaks (Quercus wizlizinii) which are of sufficient
height and girth to meet the Town of Los Gatos'
definition of a "tree" (Iaquinto, 1997). These
trees are between 12 and 15 feet tall, with three 13-inch
circumference trees, and one 17-inch tree. All of these
trees are found within the site drainage and spill
containment facility area and will need to be removed for
the proposed SPCC pond improvements (see Section IV.
Water). The drainage area is graded and considered to
have limited ecological value (ESA, 1997). Four oak trees
in the site of the SPCC pond would be removed to allow
the pond to function effectively without leakage. The
trees are young and are not considered heritage trees
(i.e., trees of great age, size and/or historical
importance). The removal of these trees would not
substantially reduce oak tree resources of the region and
the impact is considered less than significant.
Installation of the tubular steel pole may require
removal of a small blue elderberry shrub (Sambucus
caerulea) and single fan palm (Washingtonia
filifera). Both of these plants are below the minimum
height and diameter standards for Town of Los Gatos tree
protection, and therefore, their removal would be a less
than significant impact. The planted trees and shrubs on
the landscaped perimeter of the site would remain under
the proposed project. These trees would not have to be
pruned or topped to accommodate the proposed facilities,
therefore, no impact to them would occur.
- There are no locally
designated natural communities found in the project area;
therefore, no impact would occur.
- There is no wetland habitat
at the project site; therefore, no impact would occur.
- Existing poles and power
lines would be replaced to accommodate the new
substation. Location of replacement structures would be
at or near the same location as existing features. These
changes would result in no additional risks to migratory
birds, therefore, no impacts related to wildlife
dispersal or migration corridors would occur.
