Mitigation Measure 4.5-2: Impacts on Special-Status Plants.
<br /> The proposed project is located in the Central Zone of the SJMSCP. Eleven of the special-status plants listed in
<br /> Table 4.5-1 are addressed in the SJMSCP. The City will request coverage under the SJMSCP and fees will be
<br /> paid in the amount determined by SJCOG during the application and review process for the project. If SJCOG
<br /> determines,based on an independent review by a qualified biologist,that suitable habitat for special-status plants
<br /> would be affected,the following measures may be required to reduce impacts on the 11 special-status species
<br /> covered by the SJMSCP:
<br /> ► Before project construction, surveys for the 11 special-status plants covered by the SJMSCP shall be
<br /> conducted by a qualified botanist at the appropriate time of year,when the target species would be in flower
<br /> or otherwise clearly identifiable. Surveys shall be conducted in accordance with specific methodologies
<br /> described in Section 5.2.2 of the SJMSCP. If any of the 11 special-status plants are found,the following
<br /> measures will be implemented:
<br /> • Greene's tuctoria, Delta button celery, Sanford's arrowhead and slough thistle: If these species are
<br /> present in the project area and cannot be avoided, a mitigation plan will be developed,with review and
<br /> input from the regulatory agencies(e.g.,DFG). The mitigation plan will identify mitigation measures for
<br /> any populations affected by the proposed project, such as creation of off-site populations through seed
<br /> collection or transplanting,preserving and enhancing existing populations, or restoring or creating
<br /> suitable habitat in sufficient quantities to compensate for the impact. These measures will be designed to
<br /> ensure that the project does not result in a net reduction in the population size or range of Greene's
<br /> tuctoria,Delta button celery, Sanford's arrowhead, and slough thistle.
<br /> • Recurved larkspur, Wright's trichocoronis, alkali milk vetch, Suisun Marsh aster, rose-mallow, Delta
<br /> mudwort, and Delta tule pea: If these species are found in the project area and cannot be avoided,a
<br /> mitigation strategy will be developed with review and input from the regulatory agencies(e.g.,DFG). The
<br /> mitigation strategy will first consider the feasibility of establishing a conservation easement. If dedication
<br /> of a conservation easement is found not to be a feasible mitigation option,payment of SJMSCP
<br /> development fees will be used to mitigate impacts on these species. Use of conservation easements or
<br /> development fees for establishment of habitat preserves, or a combination of the two mechanisms,will be
<br /> structured to ensure that the project does not result in an overall net reduction in the population size or
<br /> range of recurved larkspur,Wright's trichocoronis, alkali milk vetch, Suisun Marsh aster,rose-mallow,
<br /> Delta mudwort, and Delta tule pea.
<br /> • The remaining two species, San Joaquin spearscale and lesser spearscale, are not covered in the SJMSCP.
<br /> Surveys for these species shall be conducted by a qualified botanist at the appropriate time of year when
<br /> the target species would be in flower or otherwise clearly identifiable. If survey results indicate that
<br /> neither species is present in project area,no additional mitigation will be required. If populations of these
<br /> species are encountered during the surveys,they will be avoided to the extent feasible. If avoidance is not
<br /> possible,plants will be evaluated for their biological importance based on the known distribution of the
<br /> plants and other pertinent data, in consultation with DFG. If significant impacts would occur, a mitigation
<br /> plan will be developed in coordination with DFG. The plan will detail specific measures to reduce
<br /> impacts on the plants to a less-than-significant level,which may include a combination of avoidance,
<br /> salvage,replanting, or protection of off-site populations as deemed appropriate by DFG. The plan will
<br /> also include methods for monitoring of mitigation success and reporting requirements.
<br /> Mitigation Measure 4.5-3: Impacts on Vernal Pool Crustaceans, California Tiger Salamander,and Western Spadefoot
<br /> Toad.
<br /> For the wastewater collection system alignment approximately 900 feet north of Yosemite Avenue and the
<br /> effluent outfall pipeline alignment,the City will request coverage under the SJMSCP and fees will be paid in the
<br /> EDAW Manteca WQCF and Collection System Master Plans EIR
