1,272 surveyed sections, drawn one square mile to a square. The shading is scaled against every county in Arizona, so a colour means the same thing on any of these pages. The outline is the county boundary from the Census Bureau: ground inside the line and outside the shading is ground nobody has drilled, filed on or addressed.

  1. Stands out

    A lot of this county is in a mapped floodplain

    57% of the county intersects a FEMA special flood hazard area, against 25% across the state. In Arizona that is usually a wash rather than a river, dry for most of the year and the reason the insurance is required anyway.

  2. Worth knowing

    Much of this county is inside an Active Management Area

    56% of the county sits in Santa Cruz AMA. Inside an AMA the state limits new groundwater pumping and a subdivision must prove a hundred-year assured water supply before it can sell lots. Outside one, almost none of that applies, and which side of the line a property falls on changes what can be built there.

  3. Worth knowing

    Almost every well here is an exempt domestic well

    65% of wells are exempt, meaning 35 gallons a minute or less for a household, against 52% across the state. Exempt wells are quick to permit and they are also the first to go dry when a larger neighbour draws the aquifer down, because they carry no protected right against it.

  4. Worth knowing

    Wells here come in weak

    The typical well makes 15 gallons a minute, against 20 gpm across the state. A household needs roughly 5 to 10, so this is liveable and it will not support irrigation, livestock at scale, or a second home on the same well.

  5. Worth knowing

    Water systems here are under enforcement

    10% of the county is served by a system with a formal EPA or ADEQ enforcement action on record. An enforcement action is the step after a violation that was not fixed.

  6. Stands out

    Most of this county is wildland urban interface

    20% intersects the wildland urban interface, against 9% across the state. That is an insurance question before it is a water one.

  7. Worth knowing

    The irrigation water here is already spoken for

    528 grandfathered irrigation rights are recorded in this county. Inside an AMA, ground that was already being irrigated in 1980 kept the right to go on doing it and no new irrigation right can be created. New ground does not get water by asking for it.

This is the county. Your question is probably a property.

None of the above is about a particular parcel. Water is not parcel-shaped: the ditch serving the ground runs through other people's land and the senior right that curtails it sits somewhere else, which is why the state files by survey section rather than by property. Check an address and you get the square mile it sits in, with the wells, the rights and what was actually diverted.
