What limits this score
57% 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))
Septic limitation not applied — servicing unknown USDA rates this soil "Very limited" for septic absorption fields, but OpenStreetMap did not answer, so nothing here establishes whether the lot sits on an established street grid with sewer service. The septic constraint is not applied to the Score. If there is no sewer, it applies in full: a standard septic system likely fails here and an engineered system can cost tens of thousands more. Confirm service with the utility, or re-run when the street read is available. (USDA SSURGO (engstafdcd); OpenStreetMap street density did not answer)
Two or more zoning districts cross this lot The city's zoning layer puts 2 districts across this parcel. Every dimensional standard on this report — height, setbacks, coverage, lot minimum — applies to a PART of the lot, not to all of it, and which part governs a given building is a question for the planning counter. Nothing here is capped for it; the numbers are simply not lot-wide. (Municipal GIS (zoning polygons intersected with the parcel ring))

Questions about this score
What is the Buildability Score™ for 30.31882, -97.56766?
30.31882, -97.56766 carries a Buildability Score of 60 out of 100 (grade C+). The score is composed from 5 weighted factors — each cited to its federal or jurisdictional source and re-runnable live on this page.
What does a grade C+ mean?
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.
Which factor most affects 30.31882, -97.56766?
The weakest factor at this address is flood — scored 58 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.
What's this parcel's strongest attribute?
Terrain scores 92 out of 100 — near flat, and the highest of the 7 factors read for this address. Higher scores mean fewer constraints, not more.
Where does the data come from?
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.
Does the Buildability Score account for local zoning in Austin?
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.
Is this an official determination?
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.
