STREET-END STORMWATER CAPTURE SYSTEM AND SLOPE STABILIZATION

eDesign Dynamics served as the water resources engineer and green infrastructure consultant to the National Fish and Wildlife Foundation and the New York State Office of the Attorney General for the design of a rain garden and slope erosion control measures in Shoelace Park in The Bronx, NY.

The goal of this project was to diminish stormwater runoff to the combined sewer, reducing combined sewer overflow (CSO), as well as to restore degraded and eroding hill slopes in Shoelace Park. CSO mitigation is achieved by redirecting runoff originating on the street and sidewalk surfaces to an attractive street-end bioretention rain garden, demonstrating how public open spaces can be integrated with stormwater reduction systems at niche locations throughout the City. Slope erosion controls are achieved by placing stone-lined swales along paths of existing runoff discharge, and bioengineering the vegetated slope area with plantings and coir to stabilize the slope. The rain garden and slope stabilization seek to demonstrate important opportunities to implement stormwater management practices within a minimal footprint and utilizing steep, marginal land.
