Green Streets in CSO 060/077 Sewershed

Project Description: This proposed project will incorporate bioswales, bioretention areas, infiltration trenches, tree trenches, and enhanced tree pits to manage stormwater at the following locations:

•       S. Salina St. Green Corridor: The proposed project includes bioswales, tree trenches, enhanced tree pits, and underground infiltration on a 10 block stretch of South Salina Street. The County received a $1.8M GIGP grant for this project through NYSEFC. Estimated runoff reduction: 4,881,429 gallons/yr

•       Elk St. Green Street: The proposed project includes bioswales between the curb and the sidewalk on Elk Street. Estimated runoff reduction: 1,293,921 gallons/yr

•       Robert Dr. Green Street: The proposed project includes underground infiltration trenches on Robert Drive Estimated runoff reduction: 1,445,206 gallons/yr

•       Moore Ave. Green Street: The proposed project includes underground infiltration trenches on Moore Ave. Estimated runoff reduction: 2,213,407 gallons/yr

•       Vincent St. Green Street: The proposed project includes underground infiltration trenches on Vincent Street. Estimated runoff reduction: 1,470,967 gallons/yr

A bioswale is a depressed, vegetated area that receives stormwater runoff from adjacent paved areas. The runoff then infiltrates to ground or is released to the atmosphere through evapotranspiration. Tree trenches and enhanced tree pits include stone trenches constructed beneath sidewalk areas to manage stormwater runoff and incorporate enhanced tree root growing space for improved long-term tree health. Infiltration trenches capture water in an underground stone trench where it then slowly infiltrates into the ground.

When complete, these green streets will capture a total of 11,304,929 gallons of stormwater annually.
