Green Infrastructure Streetscape Improvements

The City of Watervliet contracted Weston & Sampson to develop green infrastructure improvements along Route 32 as part of the New York State Department of Environmental Conservation’s Green Innovation Grant Program.

We incorporated enhanced bus stops and improved pedestrian facilities into the design for this multi-model corridor, which has a mix of residential, commercial, and light industrial uses. Green Infrastructure design elements included an underground infiltration gallery, rain gardens, bioretention areas, porous asphalt pavement, and small road-side bioretention units. An underground overflow system works to distribute the stormwater evenly, maximizing the amount of infiltration and stormwater runoff treated before conveying flows from large storm events back into the existing system. To help reduce sidewalk heaving, CU structural soil was placed underneath walks adjacent to the roadside units, which increases the root space available to new trees and other plantings.
