“Shoreline management” is defined as any tidal shoreline practice that prevents and/or reduces tidal sediments to the Bay. Shoreline management practices consist of structural or hard practices, vegetated practices, or a mix of hardened and vegetative practices often called a hybrid approach. Currently, states and local jurisdictions claim minimal nutrient and sediment reduction pollutant load reduction for shoreline projects.
In early 2013, the Urban Stormwater Workgroup convened an expert panel, facilitated by the Center for Watershed Protection, to review the science and develop protocols to estimate the sediment and nutrient pollutant load reduction associated with different shoreline management practices. This will enable the Bay states to use shoreline management practices as part of an overall watershed strategy to meet nutrient and sediment load reduction targets for existing urban development under the Chesapeake Bay Total Maximum Daily Load (TMDL).
As you can see from the map, this practice is a potentially significant nutrient reduction strategy to many communities in the Bay watershed.
This Panel’s recommendations were approved by the Water Quality GIT in Summer 2015. Congrats to all of the panelists and CWP who made this happen!
