Stormwater is excess rainfall that is not absorbed by the ground, trees, or plants. This water flows over streets and other impervious surfaces, picking up oils, sediment, and other contaminants on its way to Sligo Creek, the Anacostia River, and the Chesapeake Bay. As stormwater increases in volume and speed, it causes stream bank erosion and dumps more sediment into the stream, harming aquatic insects, fish and animals that depend on the stream for their food and habitat. The illustration to the right explains stormwater runoff graphically.
How does the City manage stormwater?
The City is making great strides to reduce the amount of impervious surface area, control erosion, and undertake projects that decrease the amount of contaminants and stormwater that enter local waterways. Some of these projects include:
- Installing bio-retention areas that use native plants and trees to filter pollution from storm runoff.
- Stream restoration and stabilization projects, such as the Circle Woods Stream project.
- Developing green streets, such as the Flower Avenue Green Street Project.
- Restricting the use of cosmetic pesticides through the Safe Grow Act.
- Maintaining stormwater infrastructure throughout the City.
What can I do to help keep the Bay clean?
Residents play a key role in reducing Takoma Park’s polluted stormwater runoff, preventing erosion, and decreasing the amount of sediment and contaminants entering our waterways and flowing to the Bay. Below is a list of some actions households can take to decrease their impact on stormwater:
- Sweep up yard debris, rather than hosing down areas and compost or recycle yard waste.
- Reduce the amount of paved and impervious area on your property. Vegetate bare spots in your yard with native plants to prevent soil erosion.
- Purchase nontoxic, biodegradable, and recyclable products whenever possible.
- Consider “BayScaping” or conservation landscaping your property. This type of yard requires very little maintenance and uses native ground cover, grasses, and vegetation.
- Install a rain barrel to collect and store rain water that would otherwise enter the stormwater system and divert into local waterways on its way to the Bay.
