Weston, FL Fence Regulations: Retaining Walls (2026)

Weston Code of Ordinances Chapter 64, the city's floodplain management chapter, addresses retaining walls directly at Section 64.77(C): "Retaining walls, Sidewalks and driveways in regulated Floodways" that involve placing fill "shall meet the limitations of Section 64.73(D)." That referenced standard, Section 64.73(D), bars any development in a regulatory Floodway, including fill or regrading, "unless the Floodway Encroachment Analysis required in Section 64.37(C)(1) demonstrates that the proposed Development or land disturbing activity will not result in any increase in the Base Flood Elevation." In practice, a homeowner or contractor building a terraced or freestanding retaining wall on a lot that falls within a mapped regulated Floodway must submit engineering showing the wall and any associated fill will not push floodwaters higher before the city will authorize the work.

Section 64.30 requires the owner or an authorized agent to apply to the Floodplain Administrator, and the Building Official where applicable, and to obtain the required permits before any qualifying development begins; Section 64.31 confirms a Floodplain Development Permit or Approval can be required in addition to a standard Building Permit. This floodway-specific engineering trigger applies only where fill is placed inside a regulated Floodway; it does not itself set a citywide retaining wall height limit outside that zone.
