Stormwater Retrofit Design

Stormwater retrofits help restore watersheds by providing stormwater treatment in locations where practices previously did not exist or were ineffective. Retrofits are an important practice for restoring watersheds since they can remove pollutants, promote more natural hydrology, and minimize stream channel erosion. Stone has identified, designed, and provided construction management support for numerous stormwater retrofits, including practices specifically targeting peak wet weather flows and phosphorus control.
