Southwest Ranches flood zones, parcel by parcel
Of the 3,413 Southwest Ranches parcels we map, 3,383 (99%) sit in a FEMA Special Flood Hazard Area — where flood insurance is required with any federally backed mortgage. City-level answers hide that the line runs street by street; this is the actual parcel count, computed from Broward County's effective FEMA layer.
The breakdown
| Zone | Parcels | Share | What it means |
|---|---|---|---|
| AH | 3,369 | 98.7% | High risk — shallow ponding, usually 1 to 3 ft |
| X | 19 | 0.6% | Minimal — outside the mapped floodplain |
| AE | 14 | 0.4% | High risk — inside the 1% annual chance floodplain |
| X500 | 11 | 0.3% | Moderate — 0.2% annual chance, the shaded X |
13% of Southwest Ranches's flood-zone homes were built before 1975 — before the first FEMA maps applied here. Pre-FIRM buildings often sit below today's base flood elevation; an elevation certificate can move the premium by thousands either way, and substantial-improvement rules limit what you can renovate without elevating.
Check the exact parcel
Zone boundaries in Southwest Ranches run down the middle of streets and sometimes straight through lots. The designation that matters — for insurance, for lending, for what you can build — is the one on the panel covering your specific parcel, with its base flood elevation where one applies.
