Stormwater Management Program
The Takoma Park Stormwater Management Program is established to achieve the following goals:
- Maintain and replace stormwater infrastructure;
- Perform stream restoration projects and other water quality improvement projects;
- Add stormwater treatment facilities, such as green streets;
- Provide funding to study, design and construct stormwater management facilities.
The Program is funded through the stormwater management utility fee, which is based on each property’s actual contribution to stormwater runoff.
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 left 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 stormwater management facilities such as 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 non-toxic, 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 rainwater that would otherwise enter the stormwater system and divert into local waterways on its way to the Bay.
My neighborhood has drainage problems. Who do I call to get some action on these problems?
You can call the City Department of Public Works at 301.891.7633. If the problem is a City responsibility, we will add it to our maintenance and repair schedule.
If you have a question about stormwater management or want to report a flooding or drainage problem, contact the City Engineer.

Stormwater Fee Calculation
The City Council passed Ordinance 2021-12 on March 24, 2021, which changed the stormwater utility fee from a flat rate of $92 per single-family property to a tiered rate based on a $25 fee per 500 square feet of the impervious area. The new fee structure was implemented in FY22. For additional detail regarding the change in fee structure, please review the City Ordinance.
For each single-family property, the Montgomery County Parcel Database was used to determine the impervious area square footage. The database contains the most up-to-date impervious area analysis data available and is based on a tri-annual LIDAR evaluation that takes aerial images of the impervious area.

Introducing: Rainplan Stormwater Calculator
This tool created by Rainplan uses high resolution aerial imagery to calculate the amount of run-off a property generates based on impervious surfaces, tree cover and soil type. The tool also provides detailed information about possible ways to manage and reduce stormwater run-off. Rainplan offers a no cost virtual site to further discuss stormwater management measures, implementation costs and available contractors.

Stormwater Utility Fee Request For Correction
If a property owner believes there is an error, a correction may be requested. Grounds for correction of the fee include:
- Errors in the square footage of impervious surface area on the property
- Mathematical errors
- Property owner identification error
Please note that impervious area totals for private property exclude public sidewalks and roadways. All public space impervious areas that appear on private property in the Montgomery County impervious area map have been deducted from private property impervious area totals. The deductions have been incorporated into the stormwater fee for applicable properties.
To request a correction, use this Application Form.
The request for correction application can be completed online or printed and returned via email to firstname.lastname@example.org or by mail to Public Works at 31 Oswego Ave, Silver Spring, MD 20910.
A property owner may be required to provide documentation, such as a property survey, composed by a registered engineer or professional land surveyor when asserting an error in impervious surface calculation.
Stormwater Utility Fee Credit Policy
The City has developed a credit program to recognize efforts already taken by private property owners to reduce stormwater run-off from their property. The maximum credit available is a 50% reduction of the original Stormwater Utility Fee. Property owners can apply for one or multiple eligible credit categories. Credits are calculated based on the amount of the impervious area treated by the qualifying stormwater control facility.
Qualifying measures include:
- Tree planting (2 tree minimum)
- Rain Garden
- Bioretention Facility
- Dry Well
- Permeable Pavement
- Green Roof
The Stormwater Utility Fee Credit Policy and Guidance Document can be found here: Stormwater Utility Fee Credit Policy and Guidance Document
To apply for a credit, use the Stormwater Credit Application Form
The Stormwater credit application can be completed online or printed and returned via email to email@example.com or by mail to Public Works at 31 Oswego Avenue, Silver Spring, MD 20910. The application does require submission of additional documentation to verify the details of the facility and the impervious area treated.
Fee Structure Rationale
- Findings: Their analysis found that the average impervious area on single-family lots was larger and had a wider variation than originally assumed, with a range from 100 square feet to 10,500 square feet. The consultants recommended the City consider changing the stormwater fee for single-family properties from a flat fee to one that is tiered and based on the actual impervious area on the property. The amount of revenue generated by the proposed new fee structure would produce the same amount of funding as the current flat fee rate. The full report can be found here.
Stormwater Management Permit
A Stormwater Management Permit is required during (a) Additions or modifications to existing single-family detached residential structures disturbing 5,000 square feet or more; (b) Any exterior construction activity on commercial, industrial or institutional property, regardless of the size of disturbance.
