Grading & Erosion Control Ordinance
Currently the State of South Dakota and the United States Environmental Protection Agency requires anyone who will be disturbing one acre or more-to have a Storm Water Permit through this state. They are also required to have a Storm Water Pollution Prevention Plan (SWPPP) to show how they will be control sediment runoff and other pollutants from leaving the property. The City of Spearfish ordinance will also require a Grading Permit and a review of the SWPPP by Public Works Staff before any grading begins.
Those who are disturbing land from 1000 square feet to one acre do not need a Storm Water permit through the State but will be required to have a Grading Permit through the City of Spearfish. Those disturbing 1/2 to 1 will need to have a Grading and Erosion Control Plan (GECP) (also reviewed by staff) to show how they will be control sediment and other pollutants on the property where the grading is taking place.
