Arapahoe County soil disturbance can trigger a GESC permit

Strip the grass off a piece of ground and the next rain will carry that loose dirt straight into the gutter, the ditch, or the storm drain down the block. Arapahoe County manages that runoff through grading, erosion, and sediment control permits, usually shortened to GESC.

The program comes in a few sizes. There is a standard GESC permit, a low-impact GESC permit, and a temporary batch plant or GESC permit for short-term setups. A standard permit is required for the listed land-disturbing activities, unless the job is small or brief enough to qualify for the low-impact or temporary version instead. Matching the permit to the scale of the work keeps a backyard regrade from being treated like a subdivision.

The whole framework ties back to stormwater rules. Its purpose is to stop sediment and construction pollutants from washing off your site and into roads, ditches, drains, and the waters downstream that other people share.

Plan for this early if a project in unincorporated Arapahoe County will disturb soil, grade land, stage construction materials, or reroute how water runs across the lot. It helps to separate two questions in your mind. A building plan answers what you are putting up; erosion control answers what leaves the property while the dirt is open and after the work is done.
