Towns in Juneau City and Borough: Juneau.
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's boroughwide study for Juneau City and Borough has 176 FIRM panels, the newest effective September 2020; coastal V zones, where waves add to the flood, are mapped along its shore.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Juneau 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 a Juneau lot shows the same lines the borough assessor draws. Juneau City and Borough covers about 1,729,922 acres of land and 355,191 acres of water.
Mapped lines are approximate. The Juneau City and Borough assessor keeps the parcel record (Juneau City and Borough website); a licensed surveyor sets the true corners.
Zoning
Juneau City and Borough zones its unincorporated land, and Juneau 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 Juneau 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 Juneau City and 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 Juneau for land inside its limits.
