Worst case

The same rule on the worst case gives no rating above the point.

Scenario

The East Block woodlots prove larger than mapped and the final layout clears more than 38 acres, but forest stays a small share of the site, so mitigation and seasonal windows remain routine.

Revision

First verdict
weakened
First critique

Category 2 is plausible, but the 41-acre forest figure and the multiflora rose and heavy-invasion claims are not in the cited quotes. The "limit to 38 acres" recommendation is misattributed, and W-3 is described as a stand when the quote calls it a wetland stand.

Revised once after the first critique. Rating unchanged.

The five inputs

  • Present: yes

    Land cover includes woodlots along Sallow Creek and on reclaimed mine ground in the East Block (C-9d4b1ab8e4), riparian forest lining most of Sallow Creek (C-e10af45ca9), and a draft layout that clears about 38 acres of trees (C-c0e63f6881). Canada thistle, a state noxious weed, is scattered on field edges (C-08f3573546). The survey found no native prairie remnants, rare natural communities or old-growth forest (C-100c2c5e80); that absence covers those communities only, and parts of the East Block woodlots were not accessible (C-421d66e93e), so it is not complete for those areas.

    Cites C-9d4b1ab8e4, C-e10af45ca9, C-c0e63f6881, C-08f3573546, C-100c2c5e80, C-421d66e93e

  • Extent: peripheral

    Cropland is 818 acres (72%) and reclaimed grassland 80 acres (7%) of the Project Area (C-67ba142a5a, C-a6c169a2d9). Woodlots sit along Sallow Creek and on East Block reclaimed ground (C-9d4b1ab8e4), and the draft layout clears about 38 acres of trees (C-c0e63f6881), small against 780 buildable acres. This is a judgment: some East Block woodlots were not accessible (C-421d66e93e), so their extent is not fully verified, and corridor or fragmentation effects are not documented.

    Cites C-67ba142a5a, C-a6c169a2d9, C-9d4b1ab8e4, C-c0e63f6881, C-421d66e93e

  • Avoidable: partly

    The draft layout clears about 38 acres of trees (C-c0e63f6881). The consultant recommends avoiding the riparian forest and the W-3 wetland stand (C-b1fad0c404; W-3 vegetation is rated under AQ-01). Some clearing for arrays and access remains, so avoidance is partial.

    Cites C-c0e63f6881, C-b1fad0c404

  • Pathway: standard

    The record shows no state forest-conversion rule, mapped rare community or contested approval. Routine measures apply: tree cutting October 1 to March 31, clearing outside the nesting season, native pollinator seed mix, vegetation management plan, and mowing outside April 15 to July 31 (C-ffa524ccb3, C-4e22698f2d, C-557a6ccbbf, C-d756845b5e). The Parcel 9 conservation easement area along Sallow Creek is to remain in natural riparian cover (C-828699d893), a siting constraint rather than a bar on the site.

    Cites C-ffa524ccb3, C-4e22698f2d, C-557a6ccbbf, C-d756845b5e, C-828699d893

  • Impact likely: yes

    The draft layout clears about 38 acres of trees (C-c0e63f6881). Canada thistle, a state noxious weed, is documented on field edges, and solar grading would disturb soil there (C-08f3573546). Clearing alone makes the impact likely.

    Cites C-c0e63f6881, C-08f3573546

Comments

Woodlots along Sallow Creek and in the East Block, with riparian forest lining most of the creek. Draft layout clears about 38 acres of trees. Canada thistle, a state noxious weed, is scattered on field edges. No native prairie, rare natural communities or old-growth forest were found, though parts of East Block woodlots were not accessible.

Critique

Verdict
upheld
Suggested direction for the rating
same
Summary

Inputs follow the evidence. The 38-acre clearing makes the impact likely, and the abstention on inaccessible woodlots is handled well. Only minor issues: easement details not in the quote, autumn olive omitted, and agency and pathway silence on tree rules.

Critic model
Luminol

Issues

  1. Severity minor · Kind unsupported_statement

    The pathway rationale places the conservation easement at 'Parcel 9' and 'along Sallow Creek'. The cited quote (C-828699d893) says only 'which is to remain in natural riparian cover.' Neither the parcel nor the creek location appears in it. Check DR-0006 for the context.

    Cites C-828699d893

  2. Severity minor · Kind missed_counter_evidence

    The East Block data-gap quote mentions dense autumn olive, a likely invasive shrub. The invasive-species discussion cites only Canada thistle. Autumn olive is a reason for the invasive plan and for the East Block survey.

    Cites C-421d66e93e

  3. Severity minor · Kind unsupported_statement

    Agencies list Carroll County and USFWS, but no claim shows a county tree ordinance. The USFWS tree-cutting window is a bat issue rated in EC-01. 'No forest-conversion rule in the record' rests on silence. Verify ODNR and the county for tree or forest rules.

Vegetation management recommendations • Seed the arrays with a low-growing native seed mix with pollinator-friendly flowering species, as ODNR's solar guidance recommends, and keep a vegetation management plan for the life of the Project. • Treat autumn olive and multiflora rose before grading in the East Block, and control noxious weeds under the Ohio noxious weed law. • Limit tree clearing to the 38 acres in the draft layout; avoid the riparian forest and the W-3 wetland stand. • Revegetate disturbed ground within 14 days of final grading, as the stormwater permit requires.
