Project: Parkway Basin Water Quality Improvement Project

Description: The Parkway Basin Water Quality Improvement Project includes the construction of 30 parkway basins in the unincorporated Los Angeles County. A Parkway is typically defined as the area between a road’s curb and the sidewalk. Parkway basins are designed to capture and treat stormwater and dry season flow (urban runoff), utilizing urban runoff for irrigation and facilitating infiltration to groundwater. These basins are constructed by excavating and lowering a portion of parkway, then cutting an opening in the curb to facilitate the flow of water from the street. The basins contain rock reinforced slopes to prevent erosion, along with the vegetation which will detain, remediate, and help infiltrate urban runoff. When a basin is full, any additional urban runoff will be unable to enter and will continue to travel in the gutter eventually to the storm drain system. Parkway basins have been successfully constructed for many years in numerous cities including: Tucson, Arizona; New York City; Portland, Oregon; and other municipalities. Locally, parkway basins have been constructed successfully in Panorama City and Studio City. RMC Objective: Protect and restore rural and urban watershed health to improve watershed storage capacity, forest health, protection of life and property, stormwater resource management, and greenhouse gas reduction.
