Before you buy or build near Larsen Bay, check the Kodiak Island Borough flood zone map: a mapped flood zone changes insurance, building rules and resale. In this Kodiak Island Borough guide: finding the address on FEMA's map, reading the zone codes, and pairing it with the Kodiak Island County ArcGIS parcel map.
Checking the Kodiak Island Borough flood zone map step by step
The official source is FEMA's Flood Map Service Center: type an address near Chiniak, and choose the dynamic map. A tract near Ouzinkie without an address is still easy to locate: search the nearest road and click the spot.
Getting to the right map
Your first stop is the Kodiak Island County ArcGIS parcel map; it includes every assessed parcel in the borough, Mill Bay included. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, whether the land is near Aleneva or elsewhere in the borough. If the land is near Ouzinkie, copy the parcel ID before closing the panel; each records desk in the borough asks for it first.
Kodiak Island Borough in a few facts
Kodiak holds the county offices, which is where the courthouse records live. Smaller places on the map include Akhiok, Larsen Bay, Old Harbor, and Ouzinkie. Around 12,565 people call Kodiak Island Borough home (Census estimate, 2023) spread over about 6,689 square miles. Kodiak Island Borough dates to 1963, so old deeds can run back a long way.
Reading A, AE and X
Near Kodiak Station, any A or V zone mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For a home near Aleneva, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Where the recorded documents are
The map is an index, not the title: deeds, plats and easements for land near Aleneva sit with the State Recorder's Office (Alaska DNR). Long-held tracts near Karluk may trace back through a long string of deeds, and a title company is worth hiring before a purchase.
A short flood checklist
If the land is near Mill Bay, ask the seller about past flood claims before closing; an insurance quote early keeps the budget honest.
When a parcel crosses a boundary
Kodiak Island Borough touches Kenai Peninsula Borough and Lake and Peninsula Borough; every one of them runs a separate parcel map. A tract near the line by Port Lions may be split in two borough records, so check the neighboring map before you assume the acreage. For a home near Chiniak, our state page lists each bordering borough map across Alaska.
Field tips
The parcel map usually runs in a mobile browser, useful out on a road near Aleneva, but coverage can be spotty out of town. A printout of the tract near Kodiak is a good backup.
Low spots and local drainage
Small streams around Old Harbor may not have detailed mapping, so look for water marks and debris lines. Wetlands near Kodiak Station can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
What the map can't tell you
Acreage on the record is an estimate; only a licensed surveyor can set the real corners for a parcel near Kodiak Station. For property near Kodiak Station, records update in batches, so a deed recorded last month might lag behind.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so check the Kodiak Island County ArcGIS parcel map too to see exactly which lot near Aleneva you're looking at.
Money questions tied to the zone
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, the lender will require flood insurance where the community participates in the National Flood Insurance Program, whether the land is near Aleneva or elsewhere in the borough. New construction in a floodplain near Kodiak Station can trigger elevation rules; check with the borough or town building office early.
Reading the legal description
Alaska uses the Public Land Survey System, which means a tract near Old Harbor is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though sections near Larsen Bay can be irregular. Write down the legal description for the tract near Kodiak Station before you request a deed or survey.
Kodiak Island Borough: common questions
What does Zone AE mean near Ouzinkie?
For property near Mill Bay, an AE zone has a 1% annual chance of flooding and a base flood elevation; unnumbered A zones don't list one.
Can I see flood zones on the Kodiak Island County ArcGIS parcel map?
Near Karluk, some county viewers include a FEMA flood layer, but FEMA's own map is the official source.
How can I tell if a house near Karluk is in a flood zone?
It depends, but FEMA's free map shows the zone for any spot near Mill Bay, which takes a couple of minutes.
What does Zone X mean near Old Harbor?
For a parcel near Kodiak Station, shaded X is moderate risk and unshaded X is minimal risk, and floods still happen outside high-risk zones.
What is a parcel ID near Old Harbor?
It's the number the borough assessor uses to track a tract near Kodiak Station, and it's on the record panel and tax bills.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
