McHenry County is classic Wisconsinan end moraine country: the Marengo Ridge and the Woodstock and Fox Lake moraine belts, with kames, kettles, ice contact ridges, and broad outwash plains between them, all drained by the Fox River, Nippersink Creek, and the Chain O'Lakes. Soils split sharply by landform. Fox, Casco, Warsaw, Rodman, and Ringwood are the gravelly to loamy well drained series on outwash and moraine crests, Griswold and Grays occupy the till slopes, and Houghton muck, Sebewa, and Drummer fill the kettles and depressions. Groundwater is shallow across much of the county, kettle wetlands are numerous and well documented, and there is more commercial sand and gravel in the ground here than almost anywhere else in Illinois.
Wetland delineation drives layout more than anything else on this ground: the kettles are real jurisdictional wetlands with high water tables, and both roads and collection routes should be laid out around them rather than through them. The upside is material, because sand and gravel is often available on site or within a few miles, so access roads can be built cheaply and dewatering is fast draining. The downside is cobbles and boulders in the till and ice contact deposits, which cause pile refusal and bent piles, so a heavier than usual geotech and pile test program pays for itself here. Slopes on the moraine ridges are the steepest ground you will grade in northern Illinois, so erosion control needs real slope treatments, not just perimeter silt fence.

We price the package as one scope under one contract, so the EPC has a single point of responsibility for the civil critical path instead of managing separate clearing, earthwork, and utility subcontracts.
Backwell superintendents, project managers, and lead operators run every site. We mobilize company equipment for the core scope and scale each project with leased production fleets, qualified regional subcontractors, and agency-placed field staff, all under Backwell supervision and a single contract.
Contractor licensing. Illinois does not issue a statewide general contractor, building, or civil sitework license. There is no state license to hold for commercial earthwork, grading, access roads, or site utilities on a solar project. Licensing for general construction is handled locally, so requirements come from the municipality or county where the work sits, and some counties require only a registration or a bond for work outside city limits. A few individual trades are licensed at the state level, including roofing through the Illinois Department of Financial and Professional Regulation and plumbing through the Illinois Department of Public Health, but those do not apply to sitework scope. The registration that does matter statewide is the Illinois Department of Labor public works contractor registration, which is required to bid or perform public works subject to the Illinois Prevailing Wage Act and is paired with monthly certified payroll filing. Contractors performing work in state highway right of way also need Illinois Department of Transportation prequalification and permits.
Construction stormwater. General NPDES Permit No. ILR10, Stormwater Discharges from Construction Site Activities, issued by the Illinois Environmental Protection Agency, Bureau of Water. The current permit was finalized September 13, 2023, took effect September 22, 2023, and expires August 31, 2028. Coverage is required for any construction site disturbing one or more acres, or a site under one acre that is part of a larger common plan of development or sale, which captures essentially every utility-scale solar site. A Stormwater Pollution Prevention Plan must be developed before construction starts, and a Notice of Intent must be submitted with enough lead time for a 30 day agency review period before construction begins. NOI fees are $700 for sites disturbing less than 5 acres and $1,000 for sites disturbing 5 or more acres. Many counties and municipalities, including several in the Chicago collar region, layer their own stormwater ordinance and permit on top of ILR10. Backwell carries the SWPPP scope, installs and maintains the controls, keeps the inspection log, and closes the permit out with final stabilization.
Prevailing wage. Federal Davis-Bacon prevailing wage and apprenticeship requirements apply through the Inflation Reduction Act to projects of 1 MW AC and larger where the owner is claiming the full investment or production tax credit rate, and that flows down to civil subcontractors through the EPC contract. Illinois adds a second, independent state layer. The Illinois Prevailing Wage Act, 820 ILCS 130, sets county-by-county prevailing rates published by the Illinois Department of Labor, requires public works contractor registration, and requires monthly certified transcripts of payroll filed through the IDOL portal. The Climate and Equitable Jobs Act extended these labor standards into the private renewable market: payment of prevailing wage is required on essentially all non-residential wind and solar projects participating in state renewable energy credit programs, and utility-scale wind and solar projects are required to have a project labor agreement. In practice a bidder on Illinois utility-scale solar civil work should assume both Davis-Bacon and Illinois prevailing wage apply, that the higher of the two rates governs, and that a project labor agreement with the applicable building trades council will be a condition of award. For projects claiming the full ITC or PTC, Backwell produces Davis-Bacon certified payroll, pays the applicable wage determination, and supports apprenticeship labor-hour compliance.
