Add Your Stormwater Practice


This Tool

Stormwater remains one of the most difficult and expensive sources of Chesapeake Bay pollution to control. According to Maryland BayStat, pollution from urban/suburban stormwater is continuing to increase in comparison to all other sources. Actions such as the installation of rain barrels, rain gardens, and green roofs; changing of lawn fertilization practices; etc. on individual properties can have significant effects on pollution reduction when aggregated at the county scale. This tracking tool provides a credible and certifiable way to account for the many privately funded, small-scale residential stormwater Best Management Practices so they can be included in and counted toward local Phase II Watershed Implementation Plan strategies. This tool was developed for UMD Sea Grant Extension by Towson University Department of Geographic Information Systems, with funding from University of Maryland Extension and assistance from Sarah Lane of UMD Center for Environmental Sciences at Maryland DNR.

University of Maryland Sea Grant Extension - Watershed Restoration Team

Watershed Restoration Specialists work with local and state governments, non-governmental organizations, and communities in Maryland to improve water quality in local rivers and streams and Chesapeake Bay by implementing restoration projects and educational programs that lead to behavior change. The purpose of this work is to facilitate the installation of Best Management Practices that will lead to quantifiable reductions in pollution from nonpoint sources and help local jurisdictions reach their Two-Year Milestone and Watershed Implementation Plan (WIP) goals while also building community engagement. The Specialists work in conjunction with the partners of the Watershed Assistance Collaborative on statewide research and pilot efforts that provide technical assistance to communities and recipients of the Chesapeake and Atlantic Coastal Bays Trust Fund and other grant programs. Each specialist serves as faculty for the University of Maryland Sea Grant Extension Program.

Getting Started

The Maryland Sea Grant hopes to collect Best Management Practices for reducing TMDL and storm water discharge into our waterways.

How you can help

The purpose of this tool is to collect information for your local government about the Best Management Practice(s) (BMPs) you have installed on your property in order to reduce stormwater pollution. Installing, tracking, certifying and maintaining these important practices are vital steps to restoring the health of your local rivers and streams and Chesapeake Bay. Thank you for your efforts!

Navigating the map

If you would like to see what other practices have been recorded in your neighborhood, type your address into the box at the top of the screen and click the Search button.

To get started, click on the green “Add BMP” button on the left. You will be asked a series of general questions about your property. When you finish filling out this form, click Next.

You will be taken to a screen entitled BMP Information with a drop-down box near the top. Click on the down arrow in the box and select your BMP. If you are not sure which BMP you have installed, you can click on the Question Mark icon to the right of the box and see a brief description of all the options.

Once you have entered the data about your BMP, click Next.

You will be taken to a screen where you can drag the address marker to the exact location on your property where the BMP is installed. You can also upload up to three photos of your BMP (must be in .jpeg format).

When you are all done, click Finish. A box will pop up that shows you the percentage Nitrogen, Phosphorus, and Sediment removal (if applicable) that you have achieved by installing this practice.

The information you entered will be made available to your county government. A trained volunteer will contact you to schedule a certification visit to confirm the data you entered. Once your BMP is confirmed, the county will be able to count this practice toward its Total Maximum Daily Load (TMDL) goal.

Thank you for your contribution to cleaner and healthier local waters!
