Landmines — flags that cap this score
⚑ 100% of the lot in a flood zone · caps this score at 60
Most of this parcel sits inside a FEMA Special Flood Hazard Area. Building is usually possible with an elevated design, but expect flood insurance, an elevation certificate, and floodplain-development permitting to stack cost onto the build. (FEMA NFHL (parcel-ring analysis))
⚑ Seasonal water table within ~30 cm
A high seasonal water table works against basements, slab moisture, and septic fields, and can require dewatering during construction. Verify with a soil bore in the wet season. (USDA SSURGO (wtdepannmin))
