The City received permits for this project from seven different agencies at the federal, state, and regional levels. These permits and associated regulations provided the requirements for protecting wildlife and the environment during the project. The regulations addressed species such as the Ridgeway rail, California black rail, and salt marsh harvest mouse; marine mammals and fish; vegetation and habitat on and around the work areas; bay water and associated wetlands. A biologist was present to monitor temporary impacts to marsh habitat during earthen fill placement, wall installation, and restoration activities.
