Site InformationLocationCloster ParkSalinas, CaLatitude/Longitude36.6814°N/121.6151°WGroundwater Depth~56 ft below ground level (fromclosest well from State WellNumber:14S03E27B001M)Hydrologic Soil GroupGroup D PROJECT DESCRIPTIONThe streets surrounding Closter Park present an opportunity to reduce impervious surfaces, introduceenhanced pavements, increase urban greening through bioretention swales, and reduce the urban heat islandeffects, all while promoting a safer pedestrian environment. The streets provide the community access to thePark where street parking and pedestrian traffic serve as the primary transportation methods to the area. Thisgreen street project effort seeks to revitalize and re-envision the surroundings streets to incorporate greeninfrastructure solutions providing improved water quality, lowering flood risk, and increasing pedestrian safety.The green street renovations will encompass Towt St., Beech St., and Dewey Ave. The proposed greenstreets intend to add popped out linear bioretention swales along each street. These bioretention swales willcapture and treat the local stormwater runoff. Adjacent to the bioretention swales will be a 10' wide permeablepavement parking section to provide additional stormwater run-off mitigation. The green street project willserve as an example of improvements that can be made to existing streets to help improve public spaces,effluent stormwater quality, and enhance community connection. Educational signage will be placedstrategically around the streets to promote a better understanding of the project objectives. This synergy canprovide a public and community benefit while improving the environmental quality of the built public space. Thestreets and park are owned and operated by the City of Salinas.
