Development and land disturbance activity can be a source of pollutants in stormwater runoff to our waterways both during construction and long-term after construction is complete. New developments that disturbs 1 acre or greater, or less than 1 acre when part of a larger common plan, are required to install stormwater control measures to minimize water quality impacts of long-term stormwater runoff from the development after construction is complete. These water quality requirements can be found in Chapter 10 of the Flood Control and Water Quality Protection Manual. This manual also contains development requirements for flood control detention, stormwater system design, stream buffers, and sinkhole protection.
Whether or not your site is over an acre, best management practices (BMPs) should be utilized to control erosion or treat the release of sediment and other pollutants associated with land disturbance and construction. For construction activity that disturbs 1 acre or greater, or less than 1 acre when part of a larger common plan, a Land Disturbance Permit will be required for the following:
