Hydroacoustic noise (i.e., underwater sound) has become a prominent issue within the San Francisco Bay along with all large West Coast estuaries. Much like the noisy urban environment, large estuaries have become a noisy place for many species. These noises can be generated by a number of human made sources including in-water construction work such as pile driving or other removal or demolition, and water vessel traffic. When these artificial sounds exceed certain levels, they can cause harm to fish and marine mammals. Consequently, hydroacoustic levels are regulated for projects that involve work within the water column, such as pier repair and installation, waterfront development, and bridge projects. The purpose of this panel is to provide attendees with a thorough understanding of the technical and regulatory elements of this issue in California and how to incorporate that information into CEQA. The panel will include experts representing sound, biology, policy, and regulatory aspects of hydroacoustics.
Panel presentations will cover a diversity of topics including: an introduction to hydroacoustics and the hydroacoustic working group; overview of the physics of hydroacoustics, sound exposure, peak levels and cumulative impacts; a biological discussion on the physiological and behavioral effects of sound on fish and marine mammals; regulatory guidelines for permitting requirements and compliance; and CEQA applications for how this issue should be addressed in CEQA documents along with example mitigation measures. Following the presentations, a Q&A and open discussion with the panel will be held for the conclusion of the session.
