Property lines
The parcel outline, parcel number and mapped size come from the Alaska borough parcel layers (each borough publishes its own), so a North Slope lot shows the same lines the borough assessor draws. North Slope Borough covers about 56,830,439 acres of land and 3,859,430 acres of water.
Mapped lines are approximate. The North Slope Borough assessor keeps the parcel record (North Slope Borough website); a licensed surveyor sets the true corners.
Zoning
North Slope Borough zones its unincorporated land, and Nuiqsut zones the land inside its limits. ParcelSheet shows the use the borough assessor lists for the lot and links the borough planning office for the district, the uses it allows and the lot size it needs.
ADU and guest houses
Under Alaska's borough planning and land use law (Alaska Statutes Title 29, Chapter 29.40), local governments can allow an accessory dwelling unit on a lot with a house. Whether a North Slope lot can add one depends on its district; the borough planning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Setbacks
Setbacks in North Slope Borough come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; the borough zoning office gives them for the lot's district, and Nuiqsut for land inside its limits.
Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near a North Slope lot and the Forest Service wildfire hazard rating at it.
