City of Los Angeles University Park Rain Gardens Design-Build
CWE designed standardized sidewalk planters (rain gardens) that treat stormwater runoff to help address the Santa Monica Bay Beaches Bacteria Total Maximum Daily Load (TMDL). The stormwater planters qualify as Best Management Practices (BMPs) and Low Impact Development (LID) solutions. Potential sidewalk planter locations within University Park, a residential area adjacent to the University of Southern California (USC), were evaluated, and 35 locations were chosen. The project involved demolition and reconstruction of parkways, curbs, and gutters so the planters could be constructed within the public right-of-way. The planter systems provide storage through various media layers and flows are able to infiltrate into the underlying soils. Additional storage and treatment is provided on the surface above the media layers within the planted area, which also provides aesthetic appeal. Lastly, the project provided public education benefits, as the community can witness firsthand how the system functions and its intended purpose.
