City of Spearfish
Grading and Erosion Control Ordinance

Who does it affect? Effective Date: March15, 2007

Currently the State of South Dakota and the US EPA 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 and 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.

“EXEMPT” Activities for Grading Permit:

Any emergency activity that is immediately needed for the protection of life, property, or natural resources.
Any nursery and agricultural operations as permitted main or accessory use.
Land disturbing activity less than 1000 square feet.

Exempt activities do not require a permit but are required to apply responsible erosion controls as needed and are subject to penalties set forth in the code of ordinances.

If project requires a Grading Permit and a Building Permit is also required, Grading Permit will need approval before building permit will be granted.
