The Mapleview Street Biofiltration and Channel Restoration Project proposes to improve surface water quality through implementation of green infrastructure and improved conveyance of stormwater flows. A series of biofiltration basins will be constructed within the shoulder of the roadway, allowing for infiltration and treatment of stormwater runoff. The project also adds additional green space, and new sidewalks to enhance pedestrian safety and mobility. Approximately 2,500 linear feet of new sidewalk and pedestrian ramps will be installed to close the sidewalk gaps along Mapleview Street between Vine Street and Pino Drive.
Drainage Area Treated: 5.8 acres
Pollutants Removed: Trash, sediment, debris, bacteria, nutrient, and metals.
What to Expect
The project is currently under construction. Construction began in mid-November 2022 and is estimated to be completed in Fall 2023.
The first phase of construction will impact the segment of Mapleview Street between Vine Street and Ashwood Street. In early 2023, construction impacts will expand eastward to Pino Drive.
Please note that
construction dates are subject to change due to compliance
requirements, inclement weather, and/or other unforeseen
circumstances. During construction, the County will make every effort
to minimize disruptions along Mapleview Street. While most work will
occur within the public road right-of-way, temporary access to private
property will be needed in some cases. There will be temporary impacts
to utilities, and to both vehicular and pedestrian traffic. Traffic
control measures, including signage placed prior to and during
construction, will be implemented to ensure the safety of our
Water Quality Improvements
When it rains, stormwater runoff will be diverted into green infrastructure elements for treatment, where natural settling and soil filtration processes will capture pollutants before they are discharged to nearby surface waters. Stormwater dispersion areas will add additional green space along the roadway.
Improvements to approximately 550 feet of storm drain conveyance
channel will improve drainage in the area.
Approxiamately 2,500 linear feet of sidewalk within the project area will be improved, along with new pedestrian ramps and driveway improvements. Pedestrians will 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.
