New techniques have been pioneered in the Chesapeake Bay watershed to restore urban streams using diverse approaches such as natural channel design, regenerative stream channel, and removal of legacy sediments.  While each approach is different, they all seek to restore the function of the stream channel by preventing sediment from bank erosion, promoting in stream denitrification, and increasing interaction with the floodplain.  The Chesapeake Stormwater Network provides a variety of resources on urban stream restoration.  In early 2012, an expert panel was convened to review the available science on the nutrient and sediment removal performance associated with qualifying urban stream restoration projects in relation to those generated by degraded urban stream channels. The panel made a series of recommendations, which were then tested, revised, and approved in 2014.  Resources include a fact sheet, a webcast, and the expert panel report.
