The assessor's comments
Construction stormwater coverage under OHC000006 required; about 96 acres of the 780-acre fenced area will be graded. Soils are mostly hydrologic groups C and D with moderate to high runoff. Sallow Creek is not impaired and has no TMDL. Basins fall below ODNR dam thresholds. Slope data not provided.
Worst case
If what is pending at the cut-off went badly, the same rule gives a higher rating.
- Scenario
Slope analysis shows C/D soils on steep slopes over much of the buildable area, requiring engineered basins and conveyance beyond standard practice.

2What the record shows
The five inputs
Present: yes
Construction will disturb more than one acre, so OHC000006 coverage with an SWP3 and post-construction treatment applies (C-4bf6e9a178, C-09073c6534; OH-SWM).
Cites C-4bf6e9a178, C-09073c6534
Extent: unknown
Soils are mostly hydrologic groups C and D (C-55cbc4b507), but slope distribution across the buildable area is not documented (no desktop hydrology in data room). Sallow Creek is not impaired and has no TMDL (C-846e2b0e13), so no receiving-water limit makes it core. About 96 of 780 fenced acres will be graded (C-4c4d92f167). Core cannot be established.
Cites C-55cbc4b507, C-846e2b0e13, C-4c4d92f167
Avoidable: yes
General-permit controls with water quality volume treatment, panel disconnection under Ohio EPA solar guidance and sub-threshold basins (about 9 acre-feet, embankments no higher than 6 feet) appear to meet requirements (C-09073c6534, C-ce17cc3949, C-ebc49abde3). No receiving-water limit identified (C-846e2b0e13).
Cites C-09073c6534, C-ce17cc3949, C-ebc49abde3, C-846e2b0e13
Pathway: standard
General permit OHC000006 with SWP3 and Notice of Intent; no individual permit or TMDL-specific limit indicated; ODNR dam permit not triggered by basin sizes (C-4bf6e9a178, C-ebc49abde3, C-846e2b0e13).
Cites C-4bf6e9a178, C-ebc49abde3, C-846e2b0e13
Impact likely: yes
Runoff-prone C/D soils with moderate to high runoff potential and planned stormwater basins show post-construction controls beyond disconnection alone (C-55cbc4b507, C-ebc49abde3). Residents raised runoff concerns (C-a82aff7176). Slope share is undocumented, so this rests on soils and basins rather than steep slopes.

State (3)
Coverage under the construction stormwater general permit OHC000006 (Notice of Intent, SWP3 and post-construction controls)
OH-SWM · Ohio Environmental Protection Agency (Ohio EPA), Division of Surface Water
- Applicability
- Required
- Instrument
- ORC 6111.03 and 6111.04; NPDES general permit OHC000006 (effective 2023-04-23)
- Trigger
- Construction that disturbs one or more acres of land, or less than one acre that is part of a larger common plan of development or sale that will ultimately disturb one or more acres.
- Description
ORC Chapter 6111 authorizes Ohio to take part in the national pollutant discharge elimination system; Ohio EPA covers construction stormwater through general permit OHC000006. Construction disturbing one or more acres, including smaller work in a larger common plan of development or sale, is eligible for coverage. To obtain it, the operator prepares a Stormwater Pollution Prevention Plan (SWP3) and files a Notice of Intent with the fee; coverage is not effective until Ohio EPA's approval letter is received. At two or more acres of disturbance, post-construction practices must treat the water quality volume, the runoff from a 0.90-inch rainfall. For ground-mounted PV arrays, Ohio EPA's solar guidance (2022-04) says impervious surface disconnection over vegetated pervious ground may be an effective approach, but it cannot manage that volume over gravel or other hard surfaces, where piling disrupts sheet flow, or where runoff is collected in swales, ditches or storm sewers.
- Typical timeline
Notice of Intent, SWP3 and fee at least 21 days before construction starts, or 45 days in the Big Darby Creek watershed and portions of the Olentangy watershed, where the SWP3 is attached to the NOI. Coverage is not effective until Ohio EPA's approval letter is received.

ODNR construction permit for a dam, including a stormwater pond embankment, above the statutory exemption thresholds
OH-DAM · Ohio Department of Natural Resources (ODNR), Division of Water Resources
- Applicability
- Conditional
- Instrument
- ORC 1521.06 and 1521.062; OAC Chapter 1501:21 (dam safety rules)
- Trigger
- A pond embankment, such as a stormwater basin, or other dam that is not exempt by size: ten feet or higher storing more than 15 acre-feet, or over six feet high storing more than 50 acre-feet.
- Description
No dam may be built to store, conserve or retard water, or for any other purpose, without a construction permit. A permit is not required for a dam under ten feet high that stores 50 acre-feet or less, for a dam of 15 acre-feet or less, or for a dam six feet or less in height, as the chief determines; in effect, a permit is needed for a dam ten feet or higher that stores more than 15 acre-feet, or one over six feet high that stores more than 50 acre-feet. Ohio's Rainwater and Land Development manual says ponds with dams are regulated under the dam safety rules (Chapter 1501:21). The application needs engineer-prepared plans with a cost estimate, a filing fee and a bond; an engineer inspects the construction, and dams are later inspected periodically.
- Typical timeline
The chief issues or denies the construction permit within 30 days of receiving the application, fee and bond or other security; dams are then inspected at intervals set by the chief that do not exceed five years.

Petition proceeding before the board of county commissioners (or joint board) for any alteration of a county or joint county ditch, respect for the county's maintenance easement, and field tile protection and repair under the OPSB rules
OH-DITCH · Board of county commissioners (or the joint board of county commissioners for a joint county ditch) and the county engineer; Ohio Power Siting Board (OPSB) (field tile requirements in the certificate application)
- Applicability
- Conditional
- Instrument
- ORC Chapters 6131, 6133 and 6137 (versions effective 2021-03-24); OAC 4906-4-08(E)
- Trigger
- The project would alter a county or joint county ditch, or build in the strip along it that maintenance crews may use.
- Description
A petition for a county ditch goes to the board of county commissioners; where land in two or more counties is affected, a joint board of the counties' commissioners conducts the proceeding. For a single county ditch the county engineer has general charge of repair and maintenance. Filling, tiling, boxing, arching, relocating or otherwise changing a ditch is an improvement, which begins with a petition to the board. The permanent maintenance easement is not more than twenty-five feet from the top of the bank on an open ditch and not more than eighty feet centered on the centerline of a closed ditch. The chapters do not themselves set out a separate ditch-crossing permit, so confirm with the county engineer what a crossing needs. The OPSB application must show avoidance or minimization of damage to field tile and timely repair at the applicant's expense.
- Typical timeline
After a petition is filed, the board sets a view between thirty and one hundred twenty days later and a first hearing thirty to ninety days after the view (ORC 6131.07(B)).

Culvert and bridge responsibilities on township roads (County Engineer's township road culvert policy); township driveway-culvert permits where required
CCO-CULVERT · Carroll County Engineer (bridges of ten feet or more) and township trustees (culverts on township roads)
- Applicability
- Likely
- Instrument
- Carroll County Engineer's policy on township road culverts (revised 2014-10-01); ORC 5571.16
- Trigger
- Building or replacing a culvert, driveway culvert or bridge, or excavating, in a township highway, or building a structure of ten feet or more on a county or township road.
- Description
The County Engineer's township road culvert policy divides responsibility. A bridge is a structure of ten feet or more clear span or diameter, and the County Engineer builds and maintains all highway bridges on county and township roads. A culvert is a structure under ten feet; its road's maintenance jurisdiction builds and maintains it, so townships handle culverts on township roads, and the county may help with replacement on a formal township request, at its discretion. A township board may by resolution require a permit for a driveway culvert or an excavation in a township highway (ORC 5571.16); the library holds no township resolution. A qualified energy project of 20 MW or more must repair roads, bridges and culverts affected by construction as the county engineer determines (ORC 5727.75(F)(4)). ORC 4906.13(B) bars a political subdivision, a township included, from requiring 'any approval, consent, permit, certificate, or other condition' for an OPSB-certificated facility; the sources do not settle whether that reaches township culvert permits.
- Typical timeline
No review period is stated in the policy or in ORC 5571.16.

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 2023-08-01.
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.
