Before an offer near Casa Grande Ruins National Monument, pull up the Pinal County flood zone map: the zone on that map shapes insurance, permits and resale. This Pinal County guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Where the Pinal County flood zone map lives
For parcel-by-parcel detail, try the National Flood Hazard Layer viewer, where zone shading sits over a photo base, which applies near Campo Bonito as much as anywhere. Rural land near Campo Bonito with no street number is still easy to locate: zoom in from the nearest road and click the spot.
Where the parcel data lives
Begin with the Pinal County ArcGIS parcel map; it maps every assessed parcel from Maricopa to Casa Grande. With a lot near Casa Grande Ruins National Monument, enter a street address, an owner's name or a parcel number, and the matching parcel lights up. On ground around Casa Grande Ruins National Monument, the record panel typically gives the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
Getting your bearings
Florence holds the county offices, which is where the courthouse records live. Other places on the map include Apache Junction, Casa Grande, Coolidge, and Eloy, each with its own cluster of lots. Around 484,239 people live in Pinal County (Census estimate, 2023) across roughly 5,366 square miles. The county dates to 1875, so old deeds can run back a long way around Eloy. Landmarks such as Casa Grande Ruins National Monument make handy reference points on the map.
What to request from a seller
For property near Arizona City, ask the seller about past flood claims before closing; an insurance quote early keeps the budget honest.
Decoding the flood zone labels
Around Coronado National Forest, zones beginning with A or V are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a home near Ak-Chin Village, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Eloy, but coverage can be spotty out of town. A saved image of the lot near Campo Bonito and its lines keeps working without signal.
Land on the county line
The county touches Gila County, Graham County, Maricopa County, and Pima County; every one of them runs a separate parcel map. Acreage along the edge near Coronado National Forest can be split across two assessors' files, so check the adjacent map before you assume the acreage. Out toward Campo Bonito, our state page links each neighboring county map across Arizona.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so pair it with the Pinal County ArcGIS parcel map to confirm you have the right parcel near Casa Grande.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, whether the land is near Campo Bonito or elsewhere in the county. Remodeling a house in a zone near Eloy usually means extra permit review; ask the local floodplain administrator before you plan.
Sections, lots and bearings
Arizona is laid out under the Public Land Survey System, so deeds around Hohokam Pima National Monument reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Campo Bonito vary in size. Copy the legal description from the record for the parcel near Campo Bonito for any title or survey request.
Water near Florence
Low-lying fields near Maricopa may not have detailed mapping, so look for water marks and debris lines. Wetlands near Apache Junction can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
Before you lean on the lines
Out toward Casa Grande Ruins National Monument, acreage on the record is an estimate; only a licensed surveyor can set the real lines on the ground. If you're looking near Coronado National Forest, owner names and values update on a schedule, so a deed recorded last month may not show yet.
