What limits this score
Sewer service assumed, not confirmed
This soil is rated "Very limited" for septic, and the septic warning is being held back only because the lot sits on an established street grid — which suggests a sewer main but does not prove one. Nothing here establishes service, connection rights, capacity, or a will-serve commitment. Confirm with the utility before you rely on it; if there is no sewer, the septic constraint applies in full.

Questions about this score
What is the Buildability Score™ for 4453 South Gabbro Way, Nampa, Idaho 83686, United States?
4453 South Gabbro Way, Nampa, Idaho 83686, United States carries a Buildability Score of 89 out of 100 (grade A). The score is composed from 6 weighted factors — each cited to its federal or jurisdictional source and re-runnable live on this page.
What does a grade A mean?
Grade A reads as a near-optimal build site with few standing constraints. The grade is derived from the numeric score (89/100) on the published Buildability™ scale.
Which factor most affects 4453 South Gabbro Way, Nampa, Idaho 83686, United States?
The weakest factor at this address is radon — scored 75 out of 100, which reads as low 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?
Flood scores 95 out of 100 — minimal risk, and the highest of the 8 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 Canyon County, ID?
When Canyon County, ID'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.
