Grading Permit Information
All Single-Family Residential Construction and Any Project Disturbing 5,000 square feet or more, within the City of Owatonna are required under the Stormwater Management Ordinance to obtain a Grading / Erosion and Sediment Control (ESC) Permit from the Engineering Department. The city will review all grading plans to ensure that there is proper site drainage, and that appropriate erosion and sediment controls are in place to prevent pollutants from leaving the construction site.
Inspections
Contractors are responsible for scheduling the initial inspection with the City, prior to the start of construction, to verify the necessary stormwater pollution prevention best management practices are in place. Contractors are also responsible for scheduling the final inspection to verify proper stabilization exists following project completion. Email the stormwater division to schedule all inspections.
