Citrus County, FL Fence Regulations: Retaining Walls (2026)

Chapter Six of the unincorporated county's Land Development Code, Stormwater Management (readopted June 22, 2026 as OA-2026-A16), regulates retaining walls that abut engineered stormwater ponds. Under section 6220(I)(2)(c), any detention or retention area with side slopes steeper than one foot vertical to four feet horizontal must be fenced, and that fencing requirement also applies at the top of any retaining wall exceeding two feet in height. The fence itself must be approved by the county, built along the outer perimeter and on top of the maintenance berm, and include lockable gates sized to allow pond-maintenance equipment through.

This sits inside a broader excavation and grading framework: side slopes without a fence cannot exceed one foot vertical to four feet horizontal, and slopes with a fence cannot exceed one foot vertical to three feet horizontal, while the maintenance berm itself may not encroach into the required setback from any sidewalk, patio, driving surface or leisure area, set at two feet or current ADA clearance, whichever is greater. This is stormwater-pond-specific: it does not set a blanket height cap or engineering-stamp threshold for every retaining wall built on a residential lot, which falls under other Land Development Code chapters administered by the county's Land Development Division in Lecanto.
