RECENT INNOVATIONS IN URBAN STORMWATER TECHNIQUES-CASE STUDY OF REGENERATIVE STORMWATER CONVEYANCES AND DISCUSSION OF OTHERS
Stormwater control and pollution load reduction techniques in the urban setting have seen some notable advances in recent years. One example now receiving stormwater credit in the Chesapeake Bay area, is the regenerative stormwater conveyance (RSC), which merges stormwater management with wetland and stream restoration and ecohydrologic principles. Applicable in urban areas under new development, retrofit, and restoration scenarios, RSC’s use sand-bedded channels, wide parabolic grade control weirs, and shallow pools to detain and cleanse stormwater runoff flows. A typical RSC site is a highly eroded stormwater outfall, draining a highly impervious area. Details of RSC design will be presented, as an example of how stormwater attenuation and cleansing functions can be approached by acknowledging and relying on ecological and restoration principles.
The discussion will expand in space and scale geographically from the water flowpaths themselves to the holistic consideration of the surrounding urban channel natural areas such as floodplains, riparian zones and forested and open space, pervious areas that contribute to urban stormwater attenuation. How approaches such as biomimicry can inform new stormwater techniques will also be explored.
