Summary of Findings Fish


Notes:

During construction, we expect to see avoidance of the area by fish, both the area around the East Bay Shoals, as well as near the platform, due to the higher turbidity conditions. During construction of hybrid alternatives and pile driving, we have seen on projects such as the Bay Bridge of the Benicia Bridge, there can be an effect to fish from the pile driving noise under water. Also, there is a potential effect to herring spawning near the runway. If they were to spawn near the runway during construction, the higher turbidity levels may have an adverse effect on the eggs. Construction may also alter migration patterns as fish swim around the construction areas, but, again, migration is not expected to be blocked.
