Worthdale Park Stormwater Project Map

Background

Worthdale Creek, East Creek, and West Creek connect and flow through Worthdale Park and continue to flow downstream to Walnut Creek. The three streams combined receive stormwater from approximately 175 acres of developed land, including impervious areas such as streets, rooftops, and parking lots. Impervious areas prevent stormwater from soaking into the ground and increases the amount of runoff and pollutants that reach the stream. The Worthdale Creek, East Creek, and West Creek streambanks have been suffering from erosion, which contributes sediment pollution to the streams and Walnut Creek.
