People often feel helpless when confronting the environmental concerns that face us today. They want to know, in simple and straightforward terms, what they can do to help. In the Chesapeake Bay watershed, the answer lies in our work to reduce the flow of nutrients and sediment into our waterways.
While we have made great strides in upgrading nutrient-removal technology at wastewater treatment plants, controlling power plant and automobile exhaust emissions, and putting conservation practices in place on area farms, we have not made as much progress in reducing stormwater runoff from homes and businesses. Rainfall continues to run across rooftops, driveways and lawns, picking up pollutants before it enters storm drains, rivers and streams. And we continue to look for ways to encourage homeowners to reduce their stormwater discharges.

Environmental regulations have not focused on runoff from homes because these pollution sources are too small, diffuse and numerous to manage effectively and efficiently. But the Chesapeake Bay Program is developing a system that will give homeowners credit for reducing their runoff and helping their communities meet the goals of the Total Maximum Daily Load (TMDL), or Bay “pollution diet.” More than 30 stakeholders worked through the Chesapeake Stormwater Network to develop this crediting program, which will respond to the needs of both homeowners and government agencies and provide an accurate mechanism for verifying residential best management practices.
Rain barrels, rain gardens and permeable pavement are just some of the tools that can help a homeowner manage runoff and add color and character to his property. But it is important for us to ensure that these practices are installed correctly to reduce pollution over time. So a guide is in production that will show homeowners how to design, construct and maintain different practices, and an online tool will allow them to add their practices to a website, where the data will be checked and pollution reductions will be calculated.
Training and certification programs are being planned. Smart phone apps are being developed. And this initiative appears to be catching on among homeowners and in communities across the watershed, where people see it as an opportunity to improve their neighborhood, increase their property values and make a positive impact on their local environment and the water quality of the Bay.
