Data Centers and Power Units Map

This bill requires the Arizona State Land Department to create maps identifying state lands suitable for data centers and power generation units, consult with industry experts, and update these maps every ten years.

What This Bill Does

  • Requires the Arizona State Land Department (ASLD) to make a map showing which parcels of state land are best for building computer data centers and facilities.
  • Directs ASLD to work with people in the data center industry when making this map.
  • Mandates that both maps (for data centers and power units) be considered by the Commissioner when planning how to use urban State Trust lands.
  • Requires the Commissioner to send copies of these maps to government officials and post them on ASLD's website.

Who It Names or Affects

  • The Arizona State Land Department
  • People who want to build data centers or power units on state land

Terms To Know

Conceptual land use plans
Plans that show how the Commissioner thinks state lands should be used in the future.
State Trust lands
Lands owned by Arizona for specific purposes, like education or public services.

Limits and Unknowns

  • The bill does not stop ASLD from processing applications for land use before these maps are made.
  • It is unclear how the maps will be used to influence actual development decisions on state lands.

Overview

Requires
the Arizona State Land Department (ASLD) produce a map identifying parcels of
state lands best suited for the development of computer data centers and data
center facilities.

History

The ASLD
administers laws related to lands owned by, belonging to and under control of
the state, which includes both trust land and sovereign land. The ASLD also
manages and controls the products and uses of state land including timber,
stone, gravel, grazing and farming (
A.R.S. �
37-102
).

The ASLD Commissioner
(Commissioner) must create conceptual land use plans for all urban State Trust
land. In creating the plan, the Commissioner must prioritize the creation of
conceptual plans to the extent possible to: 1) correlate with the rate of
population growth in the urban areas in the state; and 2) coincide with the
production of municipal general plans and county plans.

Each plan must be
revised and updated at least every ten years. The Commissioner must consult
with the city, town or county in which the land is located and with any
regional planning organization regarding integrating the conceptual plan into
the general land use plan of the city, town or county. Each plan and revision
of the plan must be submitted to the urban land planning oversight committee
for review (
A.R.S. � 37-331.03
).
