Questions about this score
What is the Buildability Score™ for 6630 WALL TRIANA HWY, MADISON, AL, 35757?
6630 WALL TRIANA HWY, MADISON, AL, 35757 carries a Buildability Score of 70 out of 100 (grade B). The score is composed from 7 weighted factors — each cited to its federal or jurisdictional source and re-runnable live on this page.
What does a grade B mean?
Grade B reads as a strong build site with minor standing constraints. The grade is derived from the numeric score (70/100) on the published Buildability™ scale.
Which factor most affects 6630 WALL TRIANA HWY, MADISON, AL, 35757?
The weakest factor at this address is soil (scored 30). 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?
Flood scores 95 out of 100 — the highest of the 7 factors read for this address.
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 Madison County, AL?
When Madison County, AL'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.
