What it can't tell you
- It doesn't look at the whole parcel, its boundaries, title, easements, zoning or permits.
- It isn't a survey, appraisal, elevation certificate, soil or perc test, or Phase I environmental site assessment.
- It can't see local distribution power lines, driveways, legal access, wells or mineral rights.
- Maps lag behind the ground, and distances are straight-line, not driving distance.
Common questions
Can I check a specific property in Yukon-Koyukuk Census Area?
Yes. Enter the address or drop a pin anywhere in Yukon-Koyukuk Census Area. The free preview shows which checks returned data at that exact point, and the full report costs $29 (initial test price).
What flood zone is land in Yukon-Koyukuk Census Area?
It depends on the exact spot. FEMA's digital flood map returned no zone at our sample point near the middle of the county, which usually means the area isn't mapped digitally. The report then says the flood zone is unknown, not safe.
Is this a survey or title search?
No. It is a preliminary screen of mapped public data at one point, not a survey, title search, appraisal, perc test or Phase I environmental site assessment.
