Stormwater runoff, or rainfall that picks up pollutants as it flows across paved roads and parking lots, is the fastest growing source of pollution into the Chesapeake Bay. But urban farms may offer an innovative way to manage that polluted runoff, according to a report from American Rivers.
Green infrastructure—such as rain gardens, green roofs and porous pavement—uses soil and vegetation to help slow the flow of runoff and manage rainwater where it falls. These projects can also offer benefits like cleaner air, reduced energy use and a boost in property values. According to the report, urban farms can offer not only the typical benefits of green infrastructure projects, but also benefits like improved nutrition and increased access to green space.
The report includes a list of ten recommendations for promoting the use of urban farms to manage stormwater runoff, such as providing training and funding opportunities for farmers, identifying vacant lots that could be converted to farms and updating city zoning codes to allow for urban agriculture.
The report, Urban Farms: A Green Infrastructure Tool for the Chesapeake Bay, is available online.
