Washington County panel continues review of commercial solar energy system rules

Washington County planning commissioners continued a multi-session review of draft guidelines for commercial solar energy systems at their evening meeting, focusing on how to define projects, whether to set minimum and maximum acreage limits, appropriate setbacks from roads and residences, fencing and vegetation standards, and engineering protections for karst geology.

Lucy Brenton, a member of the public, raised transparency concerns about project branding, saying an 8,000-acre proposal operating under the name “Hecate” could confuse landowners. “So therefore, the key key question for the record is, did land owners sign agreements with full understanding of the company's identity, branding, and cultural associations,” Brenton said, emphasizing that leases can extend 30 to 40 years.

Commission members debated terminology and metrics. One commissioner urged replacing the phrase “solar farm” with the state code term “commercial solar energy system” to avoid unintended negative associations with farming and to align local language with Indiana statute. On acreage, members weighed countywide caps (some counties use a percentage of total county or farmland acreage) against per-project limits; the transcript records county-area figures cited from public sources (about 330,000 acres countywide, 190,000 acres classified as farmland) and that existing proposals in the county were stated as “2,008” in the meeting record — numbers noted as stated by participants, not verified here.

Staff and project representatives described standard project practices for determining property boundaries and setbacks. A project representative (identified in the transcript as Speaker 3) summarized surveying practice: “It's before construction... we do an office survey. Until leases, we'll use the legal description usually from... the deed. Like you said, it's often wrong. So every single project you do, you go out and survey.” Commissioners agreed draft guidelines could require submitted plans and certified surveys before final approvals.

Setback distances used by other Indiana counties were discussed as possible models; examples cited in the meeting ranged from roughly 500 feet to 1,500 feet depending on the jurisdiction and the type of adjacent feature (dwelling, substation, road). Participants also discussed fencing and wildlife impacts, vegetative screening, and the possibility of a point system to reward developers that provide larger buffers or stronger neighbor protections. Karst topography—areas with sinkholes and underground caves that supply many private wells—was repeatedly noted as a local constraint that may require project-specific engineering plans.

No ordinance or final rule was adopted at the meeting. Commissioners asked staff to compile comparative county ordinances, technical studies (including a Purdue study referenced during the discussion), and to return with recommendations. The commission shifted later in the meeting to adopt its annual schedule of meetings and then adjourned.
