in large numbers, but sturgeon carcasses were also observed on the creek bank in
Tolay Creek monitoring. They were not identified to species, so it cannot be
known if these were green sturgeon (Takekawa et al 2002:16). Adult longfin
smelt could also occur near the Action area in San Pablo Bay. They were not
found in Tolay Creek during monitoring (Takekawa et al 2002:16).
Environmental Consequences and Mitigation
Measures
Approach and Methodology
Analytical Methods
Potential impacts on aquatic, wetland, and grassland habitats were evaluated by
comparing the quantity and quality of each type of habitat predicted to be present
at the end of the 50-year evaluation period under the No Action Alternative,
Project (Figure 3.5-4) and the Full-Tidal Alternative (Figure 3.5-5) with habitat
conditions under the No-Action Alternative.baseline conditions. Fish and wildlife
species that occur or have potential to occur in the Action area were presumed to
be indirectly affected by implementation of an alternative if the quantity or
quality of habitats with which they are typically associated would be affected.
Direct impacts on individual species were assessed qualitatively based on the
likely sensitivity or susceptibility of the species to disruption as a result of
activities that may be associated with implementation of one of the restoration
alternatives (e.g., dredging, inundation, and noise associated with equipment
operation).Consultation with USFWS, NMFS, and CDFG will be required to
determine the exact timing, however, a summary of the approximate species
protection windows during which construction may be modified or special
protection measures may be required is provided in Table 3.5-3.
