Stream restoration has been used extensively to meet Chesapeake Bay TMDL sediment and nutrient reductions goals.  Guidance found in the Expert Panel (Schueler and Stack, 2014) and MDE Accounting for Wasteload Allocations offer a framework for determining impervious acre equivalencies and increased restoration efficiencies. RES has worked with state agencies to develop methods and monitoring requirements that enable alternative crediting/efficiencies to be used.  In addition, enhanced monitoring associated with increased efficiencies better document functional uplift associated with each project.  Better demonstration of stream restoration pollutant of concern reductions has provided more cost-effective solutions and greater ecological uplift when meeting TMDL goals.
