The Peck Park Canyon Enhancement Project: Managing Stormwater Runoff in an Urban Park Setting

Through the City of Los Angeles' Proposition O Clean Water Bond, Peck Park Canyon Enhancement Project's main goal is to improve stormwater quality entering and leaving Peck Park Canyon and Dunn Canyon. This goal was achieved by reducing erosion and sedimentation, reducing downstream velocities, capturing trash and debris, and reducing the bacteria in the Canyon's stream and ultimately in the Los Angeles Harbor and San Pedro Bay. The large park facility along with the extensive trail system through Peck Park Canyon, play a vital role in the lives of local community members. Such enhancements, in addition to improving stormwater quality entering and leaving Peck Park, have provided a much more aesthetically pleasing environment for the local community and in turn will encourage the community to have a greater appreciation for the park and visit more often.The purpose of this paper is to present stormwater quality improvements through the application of numerous types of Best Management Practices (BMPs) while addressing several design challenges, enhancing the appeal of Peck Park and meeting regulatory requirements.
