The proposed structure will be located approximately 64 km 40 miles north of San Francisco, in the city of Petaluma, CA Figure 1. Channel improvements are proposed for the stretch of the Petaluma River shown in Figure 2. These improvements will improve the flow conditions of the river in this region. To prevent lowering water-surface elevations and increasing flow velocities in the regions just above the project stretch, a constriction weir was proposed. The proposed channel constriction is designed to maintain preproject water-surface elevations and flow velocities upstream of the improved channel. The preliminary design for this constriction weir was provided by the U.S. Army Engineer District, San Francisco, and based on the Corps HEC-2 algorithm.
