Weighing a property around Florence? The Casa Grande flood zone map tells you whether the lot falls inside a mapped floodplain, and it costs nothing to check. In this Casa Grande guide: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Pinal County ArcGIS parcel map.
The Casa Grande flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: search an address around Eloy, and choose the dynamic map. Rural land near Maricopa with no street number can still be found: zoom in from the nearest road then click the parcel area.
The viewer Pinal County publishes
Begin with the Pinal County ArcGIS parcel map; it maps each tax parcel around Hayden and Eloy. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, and that holds around Eloy too. For a home near Apache Junction, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Water near Coolidge
Creeks and ditches near Hayden aren't always studied in detail, so walk the land after rain. Wetlands near Apache Junction can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Casa Grande and the county around it
Casa Grande sits in Pinal County, Arizona, which means parcel data comes from the county. Local government in Casa Grande handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Acreage past the city limits out by Florence usually follows county rules rather than the town's.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Hayden, but coverage can be spotty out of town. A screenshot of the parcel near Apache Junction with its ID is a good backup.
A short flood checklist
Ask the listing agent whether the home has flooded for the house near Apache Junction; an insurance quote early keeps the budget honest.
Reading A, AE and X
An AE label includes a base flood elevation (BFE), which plain A zones lack; surveyors near Apache Junction use that number. In and around Florence, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Recorded documents worth pulling
The map is an index, not the title: deeds, subdivision plats and easements for land near Coolidge sit with the County Recorder. Long-held tracts around Florence can go back through several deeds, and a title company earns its fee on a real sale.
Neighboring parcel maps
Pinal County meets Gila County, Graham County, Maricopa County, and Pima County, all with their own assessor records. Acreage along the edge near Hayden can be split in two county records, so look at the adjacent map too. For a tract near Hayden, our state page lists every bordering county map across Arizona.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so open the Pinal County ArcGIS parcel map next to confirm you have the right parcel near Hayden.
Before you lean on the lines
Parcel lines are drawn for taxes, not measured on the ground, so a fence near Coolidge can sit some distance off the line on screen. Out toward Eloy, records update in batches, so a deed recorded last month can take weeks to appear.
A quick look at the area
Florence holds the county offices, where most land records are kept. Other places on the map include Coolidge, Eloy, and Maricopa. About 484,239 people call Pinal County home (Census Bureau estimate, 2023) across roughly 5,366 square miles. The county was organized in 1875, and some chains of title near Hayden are long. Landmarks such as Casa Grande Ruins National Monument help you orient on the aerial around Hayden.
Insurance, lenders and building
Closer to Hayden, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Hayden in a mapped zone usually means extra permit review; call the permitting office early.
