Stormwater Management Cost-Share Program: Homeowners looking for financial assistance to help resolve a stormwater issue may be eligible for funding through the City's new cost-share program. Learn more. |
Watershed Management Plan (2023)
The City is working with engineering firm Intuition & Logic to develop a citywide Watershed Management Plan to plan for future stormwater infrastructure improvements. This project is funded by the city's Parks and Stormwater Sales Tax, and will include several opportunities for public input including a questionnaire and a series of open houses.
What is a watershed? A watershed is an area of land. All the rain that falls or snow that melts within a watershed either evaporates, infiltrates into the ground, or eventually finds its way to one point. That point can be a creek, stream, river, lake, reservoir or ocean.
The City of Creve Coeur has two watersheds, Creve Coeur Creek and Deer Creek. The Creve Coeur Creek watershed is roughly the area west of I-270. The Deer Creek watershed is roughly the area east of I-270. You can learn more about watersheds at the National Geographic website or the National Ocean Service (NOAA) website.
Students from a local elementary school were learning about the water cycle and shared a glossary of terms with us. They learned a lot from this website, and we hope you and your family do too.
Open Houses
As part of the planning process, residents are invited to attend upcoming open houses.

Open House #3 Materials
- Reported Issues – Did you report a stormwater issue? If you did, you can find a one-page summary of each reported issue. The summary includes a project description and the engineering team’s recommendation. If you have additional information to share about the issue, please email DGarson@crevecoeurmo.gov or call 314-274-2107. Issues are organized geographically. The Creve Coeur Watershed is roughly west of I-270, and the Deer Creek Watershed is roughly east of I-270. View the maps below to find the yellow flag identifier associated with your project; then use that identifier to find your project description in the PDF.

- Private Projects – This display shows a map of the reported issues that were determined to be private issues. The list of criteria that the City uses to distinguish between private and public stormwater issues is also shown on this display.
- Grade Control and Bank Stabilization Details – Learn about some of the design features that can be used to address erosion and stabilize creek banks.
- Overland Flow Controls – See the different strategies that can be used to manage stormwater in yards or on streets.
- Open House #3 had displays from Open House #1 and #2 including:
How Identified Stormwater Issues Can Become City-Funded Projects
Report a concern
Do you have a stormwater concern that you would like the City to investigate? If so, please contact the Department of Public Works at (314) 872-2533, or fill out an online service request form by clicking here.
FEMA Resources
The National Flood Insurance Program (NFIP) protects U.S. residents against the hardships of flooding. To learn more about the NFIP and how it can help you, please read the Federal Emergency Management Agency (FEMA) brochure Answers to Questions about the NFIP. Even if your home is not in a high-risk flood zone, you may benefit from having flood insurance. On average, 40% of NFIP flood insurance claims are outside high-risk flood areas. Learn more with the Why Do I Need Flood Insurance brochure.
FEMA has information specifically for renters in the Flood Insurance for Renters brochure. If you live in a condo, you may want to read the brochure Flood Insurance for Condominium Associations.
Stormwater Tips
Stormwater management involves planning and accounting for how rain acts once it lands. The city encourages its residents to incorporate good stormwater management practices into their property maintenance and improvement projects.
To this end, the city’s Stormwater Committee has compiled stormwater management advice for homeowners.
MSD Project Clear - Stormwater Tips
- Illicit Discharge Prevention
- Proper Pet Waste Disposal
- Draining Household Pools Safely
- Winter Pollution Prevention
- Yard Waste Disposal and Lawn Care
Property Maintenance
- Make sure your gutters are cleaned regularly.
- Direct downspouts away from your home’s foundation so that stormwater flows away from your home.
Vegetation and Trees
- Add compost to landscape areas to promote plant roots and water soaking into the ground.
- Consider native grasses and plants that have extensive root systems.
- Add trees to your yard to provide a canopy over paved surfaces. This will provide shade, will spread out rain, and will promote stormwater infiltration and evaporation.
- Add a rain garden or a bio swale to help soak up stormwater and limit runoff.
- Add a rain barrel to one of your downspouts to collect stormwater for watering plants.
Improvement Projects
- Consider making new pathways, parking areas, or driveways out of permeable pavers so that some of the rain that hits these surfaces will soak into the ground.
- Landscaping professionals, landscape architects, and engineers can provide advice and designs for how your project can manage stormwater through grading, plantings, and best-management practices.
- Several local and state agencies provide guidance for stormwater management on their websites:
The Stormwater Committee welcomes attendance at its meetings, where residents can discuss their concerns and seek advice from the Committee. The Stormwater Committee meets every other month. The city’s meeting calendar can be found here.
