In all of Maryland's political fights over stormwater runoff pollution (remember the "rain tax"?), there was precious little conversation about the local benefits that county programs would bring. Nor did opponents ever admit that most of those programs included significant incentives for local people to join with their county governments to help solve issues like flooding. Here's the story of one of those local projects that benefited both a local waterway and its people.
Harford County, between Baltimore and the Susquehanna River, was one of the jurisdictions that objected to polluted runoff fees. Despite its long and proud history of agriculture, including preservation of close to 50,000 acres through state easements that protect that land from commercial and residential development, its relative proximity to Baltimore is driving up suburban population growth. The agricultural easements have actually concentrated most of the county's growth in the I-95 corridor and along Route 24, which crosses the interstate in the watersheds of Bynum Run and Winters Run to serve the county seat of Bel Air.
Both streams flow to the Bush River, a tributary of the Chesapeake Bay's upper Western Shore. The Bush offers habitat for waterfowl, blue crabs, yellow perch, white perch, rockfish, largemouth bass, and juvenile menhaden, but sediment runoff from developed land is rapidly filling its tidal wetlands and channels.
The Bynum Run watershed is now heavily urbanized, becoming one of the most densely populated areas in Harford County. In fact, 70 percent of the total area is covered by impervious surfaces such as paved roads, driveways, and parking lots. The Maryland Department of the Environment has listed Bynum Run as a biologically impaired waterway, damaged by channelization and smothered by sediment.
As a lifelong Harford County resident, I have witnessed stormwater flowing off our rooftops, over our lawns and pavement, down storm drains, and directly into our nearest waterway. When rain events occur, water polluted with sediment, nitrogen, and phosphorus, flows so fast that it disturbs both the bottom and the banks of the streambed, further eroding those banks and destroying habitat for the vegetation, macroinvertebrates (insect larvae), and fish that are native to the stream ecosystem.
As this year's Chesapeake Conservation Corps volunteer for the Chesapeake Bay Foundation, I decided to focus my capstone project on protecting local stream health and working in my community to promote stewardship of the Chesapeake Bay watershed. My first thought was to work with my church, Christ Our King Presbyterian Church—a medium-sized congregation, straddling both the Bynum Run and Winters Run watersheds. Throughout the 16 years of attending Sunday school, youth group, vacation bible school, and regular services at Christ Our King, I have experienced first-hand the detrimental effects stormwater has on its property.
When founded 50 years ago, Christ Our King included a single building with a small parking lot. Jump to 2015: The parish has grown to more than 500 members and gone through two building expansions, significantly increasing the cumulative area of its rooftops and parking lot. The rest of the property is turf grass, broken by one grove of trees. During this growth, channeling the roof gutters directly into a stormwater management pond was the common practice to handle surface runoff, but it only intensified the volume and velocity of runoff entering the pond.
But for the past few years, the pond has not been able to handle the volume of an average rain event, frequently flooding the lower level classrooms and activity hall, and a neighbor's property. Like preparing for a hurricane, our only defense has been lining walkways with sandbags to protect the building against the overflowing pond. To combat the stormwater issues, some fellow Christ Our King members and I set about planning and installing a series of best management practice techniques to protect our church and lessen the pollution load entering the Bynum Run watershed.
The church is Bay-Wise-certified through the University of Maryland Master Gardeners' Program. Our Care of Creation Committee focuses on environmental stewardship, enhancing sustainable landscape practices, and raising awareness in the community of how local actions affect the Chesapeake Bay and the wider world.
The Care of Creation Committee holds an annual Earth Day Celebration, which this year featured an open discussion about local stream health and overall issues affecting the Chesapeake Bay. Doug Myers, senior scientist in the CBF's Maryland Office, led the session. Twenty local community members attended, including representatives from Christ Our King, the Master Gardener Program, the Senior Science Society of Harford Community College, and CBF members.
Many of the congregation's members live in single-family detached houses in suburban communities that lie along tributaries leading to the Gunpowder, Bush, and Susquehanna Rivers. Volunteers understand that polluted runoff from impervious surfaces and agricultural practices are responsible for the existing pollution problem in local waterways. They also have remarked that there is not a lot of public knowledge on how well local governments and individual citizens are fulfilling their responsibility for protecting water quality in the area. My goal was to provide the community with the necessary tools and hands-on experience needed to create rain gardens and other Bay-friendly practices in their own neighborhoods.
