Local solar ordinance barriers, board sentiment, and utility policies that affect development timelines and risk.

55.4

Ordinance & Regulations

Setback Requirements
Apache County ZO: 150 ft from occupied structures, 50 ft from property line for utility-scale in Agricultural/Range zones. Navajo Nation has separate NNLAC (Navajo Nation Land Administration Corp.) permitting with tribal council approval required.
Zoning Mechanism
CUP via Apache County Board of Supervisors for non-tribal land. Navajo Nation land requires NNLAC lease, tribal council resolution, and BIA trust land approval — multi-year process.
Acreage Caps
None codified on county land. Navajo Nation leases negotiated case-by-case.
Density Caps
None codified.
Spacing Rules
None codified.
Size Restrictions
No county size restriction. Navajo Nation leases may specify acreage.

Board Sentiment & Political Risk

Sentiment Analysis
Complex — non-tribal areas are conservative with limited political enthusiasm for large solar; tribal land has separate governance with growing interest in energy sovereignty but slow approval timelines.
Basis for Assessment
Apache County Board of Supervisors is predominantly conservative; Navajo Nation governance adds sovereign approval layer; tribal energy sovereignty movement supports solar but process is lengthy; county has high poverty rates, low tax base.
Political Risk Factors
Worsening
Board Members
Apache County Board of Supervisors: Tom M. White Jr. (Chair, District 3) | R | 2026; Alton Joe Shepherd (District 1) | R | 2026; Delwin Wengert (District 2) | R | 2026.
