Weighing a property around Wasilla? The Palmer flood zone map tells you whether it sits in a FEMA flood zone, and it costs nothing to check. This Palmer guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Getting started with the Palmer flood zone map
Flood zones come from FEMA's Flood Map Service Center: search an address around Houston, then open the map view for that panel. Rural land near Houston with no street number is still easy to locate: search the nearest road and click inside the land.
The free map to start with
Your first stop is the Alaska Statewide Parcels layer in ArcGIS Map Viewer; it covers every tax parcel around Houston and Wasilla. For a tract near Wasilla, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. Copy the parcel ID while you have it open; every records desk in the borough uses it to find the file.
Where Palmer fits in
Palmer lies within Matanuska-Susitna Borough, Alaska, which means parcel data comes from the county. Palmer is also the county seat, so deeds and plats are filed in town. In and around Wasilla, city or town hall handles matters such as zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Land beyond the city limits toward Houston usually falls under county rules rather than the town's.
Legal descriptions in Alaska
Alaska uses the Public Land Survey System, which means a tract near Houston is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Wasilla vary in size. Write down the legal description for the tract near Houston before you request a deed or survey.
Decoding the flood zone labels
For a parcel near Houston, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For a home near Wasilla, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Low spots and local drainage
Small streams around Wasilla aren't always studied in detail, so ask neighbors about past flooding. Wet ground around Wasilla is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Lining it up with the parcel map
FEMA doesn't draw property lines, so pair it with the Alaska Statewide Parcels layer in ArcGIS Map Viewer to confirm you have the right parcel near Wasilla.
Money questions tied to the zone
For a structure inside an A or V zone and the loan is federally backed or regulated, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, whether the land is near Houston or elsewhere in the borough. Remodeling a house in a zone near Wasilla often needs a floodplain permit; check with the borough or town building office early.
Offices that can help
For assessment questions about property around Wasilla belong with the borough assessor, since that office keeps the assessment data. Questions about what you can build around Wasilla go to planning, building or health offices, town or borough, depending on location.
A quick look at the area

When a parcel crosses a boundary

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.
