Information on Nutrient and Sediment Best Management Practices
Mid-Atlantic Water Program BMP Report
This report led by the University of Maryland Mid-Atlantic Water Program includes nutrient and sediment reduction effectiveness estimates of select agricultural, stormwater and forestry best management practices (BMPs). With funding from the Chesapeake Bay Program Office, the Mid-Atlantic Water Program developed definitions and effectiveness estimates for BMPs that states were implementing or proposing to implement as part of their efforts to meet the nutrient and sediment reduction goals necessary to restore the Bay. The report provides realistic, science-based estimates of expected nutrient and sediment reduction performance from these BMPs and reflects current research and knowledge as well as average operational conditions representative of the entire Chesapeake Bay Watershed.

Scenario Builder BMP Values
This table contains documentation for BMPs credited in Scenario Builder based on BMPs reported as used by the states. BMP reduction efficiencies for total nitrogen, phosphorus and sediment as well as the type of credit given in Scenario Builder for the BMPs are noted within.
Effectiveness Shapefile
This shapefile was used to create Maps of the Nitrogen and Phosphorus Effectiveness throughout the Watershed (10/2009). Any questions may be directed to Guido Yactayo at gyactayo@chesapeakebay.net.
Resources for Watershed Implementation Planning Process
Below one will find a brief description of resources, tools, and existing projects that can support the States and D.C. in the development of Watershed Implementation Plans.
Model Segmentation Viewer
The segmentation viewer allows partners to overlay Phase 5 Watershed Model Segments with layers including streets, satellite imagery, shaded relief, MS4 areas, 12-digit watersheds, and counties. This tool will allow local planners the ability to see and verify where specific segments are in relation to other boundaries and features, aiding in the decision-making process.
