While St. Louis is not on an ocean coast, the city sits on the western bank of the Mississippi River. Development along the riverfront is regulated through the city's zoning code and the Riverfront Overlay District. The Gateway Arch National Park and levee system dominate the downtown riverfront. Floodwall and levee setbacks apply to properties near the river. The city works with the U.S. Army Corps of Engineers on flood control along the Mississippi.
St. Louis regulates development near rivers, streams, lakes, and wetlands through buffer zone requirements and environmental review. Riparian setbacks typically range from 25 to 100 feet depending on waterway classification. Wetland fill or alteration requires federal Army Corps of Engineers permits. Floodplain development restrictions apply within FEMA-designated flood zones. Streambank stabilization projects need permits. Environmental impact assessments may be required for larger projects near water resources.
Building in buffer zone without permit: stop-work and fines $500 to $5,000. Wetland violations: federal fines up to $25,000 per day. Unpermitted streambank work: restoration orders.
