RiverSmart Schools Low Impact Development Project – Year 1

Low Impact Design (LID) stormwater features at DC three schools create new educational opportunities while also improving water quality, habitat, and biodiversity in a densely urban environment.

Washington, DC’s RiverSmart Schools program aims to improve water quality in the Anacostia River watershed while also enhancing wildlife habitat, highlighting water conservation, and providing public school students with new opportunities to learn and play outdoors. Through a multi-year design-build contract with DC’s Department of Energy & Environment Biohabitats is creating Low Impact Development stormwater features at three District schools per year.

In the first year of this effort, Biohabitats worked with three schools that were grappling with standing water, soil compaction, and overall poor drainage. One was newly constructed and two were built before the establishment of stormwater regulations. After conducting ecological assessments of each site, Biohabitats developed conceptual designs for the features. These included bioretention, raised planters, large cisterns, outdoor classroom areas, and the replacement of impervious area with a vegetated swale.

Throughout the projects, Biohabitats and DOEE engaged faculty and staff from each school to gain their input, enhance their understanding of the proposed concepts, and discuss ways to integrate the new features into school programming. Biohabitats then prepared final design documents and implemented construction, which included volunteer planting days with students and the installation of interpretive signage.

With the collective capacity to store 100 CY of stormwater per rain event, the new features improve drainage, biodiversity, and outdoor experiences at the schools while also positively impacting water quality for the entire watershed.
