A street designed to: • be a visible component of a system of "green infrastructure" that is incorporated into the aesthetics of the community • integrate a system of stormwater management within its right of way • reduce the amount of water that is piped directly to streams and rivers • make the best use of the street tree canopy for stormwater interception as well as temperature mitigation and air quality improvement CRWA e tertownTF e all about ...fhis town.'" Green Street Benefits • Water quality improvements and volume reductions in stormwater being discharged into receiving bodies of water • Key linking component in community n i s efforts to develop local green infrastructure;;+ � networks • Improves local air qualitybyproviding - interception of airborne particulates and shade for cooling • Reduces heat island effect • Increases property values • Calms traffic and improves pedestrian experience along the street right of way CRWA Hague St., Allston X- CRWA Green Street: Local Examples i� W.21. , - ',t 11IMMAWL, -.411M 0 Crescent Ave,, Chelsea Western Ave., Cambridge Foster St., Cambridge TF ublic . �rk� Watertown tertown Edenfield Avenue -Proposed Road Diet TOWN RIGHT-OF-WAY 32'-9"± EXISTING ROADWAY 5'-0" 7'-0" 26'-0" 7'-0" 5'-0" SIDEWALK GRASS OR PROPOSED ROADWAY GRASS OR SIDEWALK GREEN GREEN INFRASTRUCTURE INFRASTRUCTURE AREA AREA EXISTING PAVEMENT ELEVATION EXIST.
