Any person required to submit an application for a grading permit under this chapter shall develop one of the following site specific stormwater management plans:
(1) SITES GREATER THAN ONE ACRE OF LAND DISTURBANCE. A stormwater management plan shall be developed in accordance with s. NR 216.47 prior to submitting an application for a grading permit to the department. The plan shall be implemented upon final stabilization of the grading site.

Examples may include directing downspouts onto lawns and away from pavement, driveways sloped onto lawns, and avoidance of piping or channelizing flow from impervious areas into waters of the state. The plan shall be implemented upon final stabilization of the grading site.
