68% 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))
Each factor is scored 0–100. Higher means fewer constraints.

30.26512, -97.75218 carries a Buildability Score of 60 out of 100 (grade C+). The score is composed from 4 weighted factors — each cited to its federal or jurisdictional source and re-runnable live on this page.
Grade C+ reads as a scored buildability read across zoning, flood, seismic, soil, radon, wildfire, and utility factors. The grade is derived from the numeric score (60/100) on the published Buildability™ scale.
The weakest factor at this address is flood — scored 51 out of 100, which reads as moderate risk (every factor is scored so that higher means fewer constraints). That's the factor most likely to constrain what a design can carry, and the one to inspect first before committing capital.
Seismic scores 90 out of 100 — minimal risk, and the highest of the 6 factors read for this address. Higher scores mean fewer constraints, not more.
Every factor cites the federal or jurisdictional dataset it came from — FEMA (flood), USGS (seismic), USFS (wildfire), EPA (radon), USDA/NRCS (soil), and the local jurisdiction's own zoning record where available. Sources are queried live and re-run on refresh; the score cannot outrun its data.
When Austin's zoning record is on our roster, the score reads the jurisdiction's own dimensional standards for the district this parcel sits in. When it isn't, the zoning factor drops out rather than being estimated — which is why parcels in un-rostered jurisdictions still return a score, just one that doesn't count zoning.
No. The Buildability Score™ is a preliminary due-diligence read, not an entitlement or permit approval. Governing bodies retain sole authority over binding land-use decisions. The score's role is to make the diligence conversation faster and better-grounded, not to replace it.
