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

Section 114-3(j) folds erosion and sediment control into the county's broader surface water management inspection sequence, which applies to any development subject to Section 114-3, from single-family lots expanding impervious area to commercial sites building new stormwater systems in the unincorporated Keys. The applicant arranges the erosion-and-sediment-control inspection with the Planning Director, who may schedule it together with the dewatering, bury and final inspections already required for the project's stormwater management plan. Control measures must be installed and stabilized around the perimeter of the construction area both during and after construction, so runoff and sediment stay on site rather than reaching the near-shore waters, canals and wetlands the surrounding sections of Chapter 114 are written to protect.

If the Code Compliance Officer who inspects the work finds it out of compliance, the Planning Director sets a correction deadline based on how long the fix takes and how the violation affects water and habitat quality; work that is not corrected is subject to the penalty provisions of Section 114-3(k), including a stop-work order from the Building Official and denial of the certificate of occupancy. Beyond the construction-phase inspection, Section 114-3(j)(1) makes the owner or approved operating entity responsible for maintaining the installed system afterward: if the Planning Director gives written notice of needed corrective action and the owner does not act within 30 days, the Board of County Commissioners may perform the work itself and place a lien on the property to recover the cost.
