Crediting Residential BMPs

RainGardenGuide

In the Chesapeake Bay watershed, one of the greatest threats to the health of the Bay comes from increased development of the land. Increased development and transformation of the landscape leads to less rainwater soaking into the ground where it is naturally filtered before returning to our streams and rivers. Instead, more water “runs off” our properties and travels along our impervious corridors of driveways and streets picking up pollutants along the way which are then delivered to our streams and ultimately the Chesapeake Bay.

The Urban Stormwater Workgroup along with the other CBP review workgroups has recently approved the crediting of on-site LID practices or “homeowner BMPs” as they have come to be known for credit in the Watershed Model. So what does that mean? It means that localities and states can now take credit for these practices and apply it toward meeting their Bay TMDL load reductions. While individually, load reductions from on-site practices are not too impressive…across a community and over 15 years, they can really add up !

To learn more about this particular restoration practice read the protocol developed (and approved!) to allow localities to get nutrient reduction credit in the Chesapeake Bay Watershed Model for the installation of verifiable homeowner BMPs.

Application of CBP-Approved Urban BMP Protocols to Credit Nutrient Reduction Associated with Installation of Homeowner BMPs

This memo outlines the recommended protocol to get nutrient reduction credit in the Chesapeake Bay Watershed Model for the installation of verifiable homeowner BMPs. The USWG has approved a memo outlining guidance on crediting of homeowner BMPs (USWG, 2013). This memo includes WTWG-approved guidance to simplify and streamline reporting of homeowner BMP data, as outlined in Section 2.

Homeowner Guide For a More Bay-Friendly Property

This guide presents a step by step approach for analyzing your property to find out whether it makes sense to install a rain garden or other residential stewardship practices. We then take you through the design and installation of several of the homeowner practices, so that you can install them on your own. Many Bay communities offer technical and financial assistance to help you install stewardship practices on your lot. Check out Appendix D for a list of links to these programs.
