In Saint Louis MO, any construction or landscaping activity that disturbs the land surface may require a land disturbance permit. This permit ensures that projects comply with environmental regulations, particularly those related to stormwater management and erosion control. Understanding the permitting process is crucial for developers, contractors, and property owners to avoid potential fines and project delays.
What is a Land Disturbance Permit?
A land disturbance permit is an authorization required for activities that disturb the soil, such as grading, excavating, or filling. The permit ensures that appropriate measures are in place to prevent soil erosion and manage stormwater runoff during and after construction.

-
Disturbance of one acre or more of land.

Projects that are part of a larger common plan of development that cumulatively disturb one acre or more.

It’s important to consult with the St. Louis County Department of Transportation and Public Works to determine if your project requires a permit.
