Comprehensive Legacy Sediment Removal and Multi-Benefit Outcomes_ Ehrhart
While comprehensive legacy sediment removal floodplain restoration projects provide
significant ecological uplift, they also provide numerous other benefits that bring value to
communities. These ancillary benefits can drive additional funding opportunities that
ultimately allow more restoration work to be completed under various programs. These
benefits include sediment and nutrient reductions that can meet MS4, Chesapeake Bay, and
local TMDL targets, peak attenuation and volume reduction that can meet post construction
stormwater management requirements for land development activities, groundwater recharge
that can offset consumptive water use, and local and regional flood hazard mitigation. Case
studies will be discussed demonstrating the effectiveness of floodplain restoration projects in
providing multiple benefits.
