Urban Stormwater BMP Expert Panel Reports
Below are the most recent Chesapeake Bay Expert Panel Reports that have completed the Chesapeake Bay BMP Protocol Process. These reports detail the process and conditions necessary to obtain a nutrient or sediment credit thru the Chesapeake Bay modeling system. As new urban BMP Expert Panel Reports are developed, or updated, they will be added to this section.
Chesapeake Bay Program BMP Guide
The Chesapeake Bay Program has just released a new Chesapeake Bay Program BMP Guide: "A Quick Reference Guide for Best Management Practices: Non-point source BMPs to Reduce Nitrogen , Phosphorus and Sediment in the Chesapeake Bay and its Local Waters". The BMP Guide provides summarized profiles for each CBP-approved BMP in the Phase 6 Watershed Model. This “first edition” of the guide includes the majority of the urban and agriculture BMPs, and all of the highly utilized practices. The “second edition” of the BMP Guide (release date TBD) will include the less utilized BMPs (e.g., biofilters, legume covers, poultry litter amendments), septic BMPs, and any BMPs that are currently being reviewed by expert panels.
Each reference sheet includes basic general information about a BMP, how it functions within the Watershed Model, what’s needed for the BMP to be reported for annual progress submissions, as well as links to additional information for those who want more detailed information about the practice. Implementation aspects of a practice, such as cost, potential ecosystem co-benefits or impacts, maintenance or funding sources are not discussed in the reference sheets because such information varies based on the characteristics and priorities of a region, state or local area.
