Mapleview Biofiltration and Channel Restoration Project Image


The Mapleview Street Biofiltration and Channel Restoration Project has been completed. The project improved surface water quality through implementation of green infrastructure and improved conveyance of stormwater flows. A series of biofiltration basins was constructed within the shoulder of the roadway, allowing for infiltration and treatment of stormwater runoff. The project also added additional green space, and new sidewalks to enhance pedestrian safety and mobility. Approximately 2,500 linear feet of new sidewalk and pedestrian ramps were installed to close the sidewalk gaps along Mapleview Street between Vine Street and Pino Drive. Additionally, new driveway aprons were placed along the street to improve safety and mobility in the area. In partnership with State Water Resources Control Board, the project also added two educational signs, describing the water quality benefits and community enhancements from this project.


Community: Lakeside

Drainage Area Treated: 5.8 acres

Pollutants Removed: Trash, sediment, debris, bacteria, nutrient, and metals.


Mapleview Street Stormwater Dispersion Area


Water Quality Improvements

When it rains, stormwater runoff is diverted into green infrastructure elements for treatment, where natural settling and soil filtration processes capture pollutants before they are discharged to nearby surface waters. Stormwater dispersion areas added additional green space along the roadway.

Improvements to approximately 550 feet of storm drain conveyance channel improved drainage in the area.

Mapleview Street Sidewalk Improvements


Sidewalk Improvements

Approximately 2,500 linear feet of sidewalk within the project area have been improved, along with new pedestrian ramps and driveway improvements. Pedestrians can now enjoy additional buffer space between sidewalks and street traffic.


Funding for this project has been provided in part under the Proposition 1 - the Water Quality, Supply, and Infrastructure Improvement Act of 2014 through an agreement with the State Water Resources Control Board.
