Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA has 166 FIRM panels covering Anchorage Municipality, the newest effective September 2019; no coastal V zones are mapped in it.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for an Anchorage house comes from a licensed surveyor and is often on file with the borough or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the Alaska borough parcel layers (each borough publishes its own), so an Anchorage lot shows the same lines the borough assessor draws. Anchorage Municipality covers about 1,092,349 acres of land and 152,136 acres of water.
Mapped lines are approximate. The Anchorage Municipality borough assessor keeps the parcel record (Anchorage Municipality website); a licensed surveyor sets the true corners.
Zoning
Anchorage Municipality zones its unincorporated land, and Anchorage 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 an Anchorage 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 Anchorage Municipality 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 Anchorage for land inside its limits.
Hazards that apply
- Wetlands and wildfire. ParcelSheet shows the National Wetlands Inventory near an Anchorage lot and the Forest Service wildfire hazard rating at it.
