The Wildcat and San Pablo Creeks Flood Control Project is located in Richmond, California. Both streams flow through a highly urbanized area, periodically overflowing their banks and causing extensive flooding and sedimentation damage. Construction of the proposed project will result in some loss of native vegetation and wildlife habitat. These losses will be minimized by selective alignment of the project channels, and further offset by the incorporation of environmental mitigation and enhancement features. The case study presents how stable channel design concepts, coupled with enhancement features requested by area environmental groups, played important roles in the design of the project configuration. The study also includes a discussion of a sediment transport model and sediment budget used to verify project channel performance.
