Uncontrolled erosion and the lack of sediment controls on a construction site can result in sediment leaving the site. This pollutant can negatively impact water quality in downstream creeks, rivers, and ultimately the Gulf of Mexico.
Recognizing this fact, and in order for the City to comply with the federal Clean Water Act, the City adopted an Erosion & Sediment Control Ordinance requiring that before any construction activity that results in an acre or more of land-disturbing activity (or bare soil) can begin, an Erosion & Sediment Control Permit (ESC Permit) is required.
Construction activity smaller than an acre may also require permit coverage if they are part of a larger common plan of development or sale, are required to be covered by an NPDES permit. Sometimes individual lots, smaller than an acre, are required to obtain permit coverage prior to construction.
