To learn more about Gallinas Creek dredging and its relationship to the Proposed Santa Venetia Floodwall Project, please review the Santa Venetia dredging update and the County Service Area 6 webpage. Elevation map Project map The engineering firm’s work has been reviewed by Flood Control District staff throughout the design process, and updates were shared throughout 2022 at community meetings on July 27 and September 14, as well as at the October 13 Flood Zone 7 Advisory Board meeting. A report of the project design was released in October 2022. An updated report on the project design was released in March 2023. The recommended design was brought to the Board of Supervisors in March 2023. The design consists of a composite sheet pile floodwall extending approximately 1.5 miles along 111 properties on the bank of Gallinas Creek in Santa Venetia.   The project was re-scoped in March 2022 following a cost estimate that exceeded available funding and, in July 2022, began a new design process led by a new engineering firm. The purpose of this public safety project is to reduce flood risk for 576 households in the community of Santa Venetia, a low-lying area near San Pablo Bay, which is facing the impacts of sea level rise. The proposed project would be designed to reduce the risk of flooding for the community during 100-year water surface elevation on the Bay.
