Title
Mapleview Street Green Streets Project
Description
The proposed Mapleview Street Green Streets Project would improve stormwater conveyance and water quality along Mapleview Street through implementation of structural stormwater best management practices. The project occurs along approximately 0.69 miles of Mapleview Street from Vine Street to Pino Drive located within the unincorporated community of Lakeside in San Diego County. Runoff from rain events, ground water infiltration, and irrigation activities flows into the County’s Municipal Separate Storm Sewer System with limited treatment before entering the San Diego River. The goal of the project is to improve water quality by treating wet weather flows along Mapleview Street to help meet indicator bacteria Total Maximum Daily Load targets in the San Diego River watershed. Proposed improvements include installation of approximately 460 linear feet of 5-foot wide sidewalks, 200 linear feet of a 3-foot wide cobble-lined swale, and 550 linear feet of 4-foot wide biofiltration basins along Mapleview Street between Vine Street and Ashwood Street. The existing unlined roadside ditch would be improved with an 8-foot wide dispersion area. Strom drain improvements would occur at the intersection of Ashwood Street and Mapleview Street and would continue east along the north side of Mapleview Street for approximately 450 feet. East of the storm drain improvements, 8-foot wide biofiltration basins would be constructed within the shoulder of the roadway. The sidewalk, curb, gutter, driveway, and road improvements would continue along Mapleview Street and terminate west of Pino Drive.
