Leon County, FL Environmental Rules: Erosion Control (2026)

Leon County's stormwater and environmental standards are aimed at preventing erosion, sedimentation and water-quality problems in surface waters. Section 10-4.303 includes minimum access stabilization requirements to stabilize new roadway accesses against erosion and sedimentation. As part of the Environmental Impact Analysis, Best Management Practices (BMPs) must be shown on the site plan for all properties located within Special Development Zones (designated Zone A and Zone B environmentally sensitive areas under §§ 10-4.301 and 10-4.323). Development applications must delineate and protect altered and unaltered floodplains, wetlands, waterbodies, and watercourses, and underbrushing or vegetation removal within any unaltered or naturally vegetated floodplain or wetland may not occur before a vegetation management plan is submitted and approved. Land-disturbing development requires an Environmental Management permit from DSEM, and projects submitted in response to enforcement action are tracked on the permit application. Construction activity disturbing one or more acres is separately regulated under Florida's NPDES stormwater construction permitting administered by the Florida Department of Environmental Protection — a state/federal requirement layered on top of the County code.
