REGENERATIVE STORMWATER CONVEYANCE: TECHNIQUES TO WATERSHED STEWARDSHIP & TURNING STORMWATER LIABILITIES INTO AMENITIES

Abstract

Regenerative Stormwater Conveyance (RSC) is a moderately new best management practice primarily implemented in the mid-Atlantic region. This thesis documents the proposed design of an RSC at Parkdale High School in the Washington D.C. metropolitan region. A degraded channel with incised banks between 9 to 12 feet in height was found on site. This stormwater channel runs for 160 feet and has a contributing catchment of 17.2 acres.

The proposed RSC was designed to stabilize the channel banks, and create a stable channel profile. The runoff storage volume was calculated to be 4523.1 ft3 total which would treat a runoff volume of 0.24”. This equates to 32% TN, 37% TP and 40% TSS removal. The design provides a viewing area with a photo point and bank pin that would provide an opportunity for students and teachers to assist in visually documenting sediment deposition and geomorphological changes that may occur.
