The assessor's comments

No geotechnical investigation or karst, mine, or oil and gas well mapping is included in the data room. Presence of geohazards in the Project Area is not addressed. Desktop geologic review and geotechnical investigation would settle it.

Conclusion withheld

Question
Are karst, abandoned mines, oil and gas wells, steep slopes or other geohazards present in the Brook Hollow Solar study area?
Missing evidence
Geotechnical investigation or desktop geotechnical study; karst, mine, or oil and gas well mapping.
Consequence
Foundation design, layout setbacks and possible cost or schedule exposure cannot be rated until hazards are screened.
Information request
Provide any geotechnical reports, state geological survey mapping, or oil and gas well and mine records covering the 1,356-acre Project Area.
Blocks the decision
No

2What the record shows

The five inputs

  • Present: unknown

    No evidence claims address karst, mines, oil and gas wells, steep slopes or other geohazards. Neither a geotechnical study nor hazard mapping is in the data room, so presence cannot be established or ruled out.

    Cites no claim.

  • Extent: unknown

    No evidence on any geohazard, so extent relative to the buildable area is not established.

    Cites no claim.

  • Avoidable: unknown

    No evidence on any geohazard, so avoidability by setbacks or siting is not established.

    Cites no claim.

  • Pathway: none

    Placeholder because presence is unknown; no evidence of any required approval.

    Cites no claim.

  • Impact likely: no

    Placeholder because presence is unknown.

    Cites no claim.

5Next steps and agencies

Next steps

  • Desktop review of state geological survey karst, mine and oil and gas well mapping for the Project Area.
  • Commission geotechnical investigation, including pile load testing, and site visit to confirm hazards.
  • Request any existing geotechnical data from the developer.

Agencies

  • Indiana Geological and Water Survey
  • Indiana DNR

6Basis and limits

This report is a desk review of the documents quoted above, as the engine read them for an information cut-off of 2023-08-15.

It is not a field survey and not a modelled study: this review made no site visit and ran no acoustic, hydraulic or other model. Where the record is silent, the report says what is missing; it does not fill the gap.

Every statement, figure and quote is the engine's record as written. The headings and connecting words are fixed text of this room, the same in every report.
