Complete civil packages for utility solar in Clay County, Mississippi: clearing, mass grading, access roads, collection trenching, SWPPP, fencing, and substation civil.
Backwell is a civil site work general contractor serving utility solar EPCs building in Clay County, Mississippi. We contract the complete civil package under one agreement, with Backwell superintendents and lead operators on site.
Clay County is the TVA side of the Mississippi solar market and holds two large Origis Energy projects. Optimist, a 200 MWac solar plus 50 MW storage facility, was slated to reach commercial operation in early 2026. Hope, a 200 MWac solar plus 200 MW and 800 MWh storage facility, is targeted for the end of 2028, which puts its civil procurement in the 2026 to 2027 window. Battery storage scope adds concrete pads, heavier access roads, and tighter grading tolerances to the civil package.

Eastern Clay County is Black Prairie developed on the Cretaceous Selma Chalk, a weathered rolling plain of dark calcareous clay. The classic series are Houston, Okolona, Brooksville and Sumter, with Demopolis and Binnsville running shallow to chalk on the knobs and side slopes. These are smectitic Vertisols: alkaline, high in calcium, swelling when wet and cracking deeply when dry. Moving west the county drops into the Flatwoods belt where Kipling and Vaiden clays sit over dense acid clay, then into sandier Coastal Plain uplands. The Tombigbee River and the Tennessee-Tombigbee Waterway form the eastern edge of the county, with Mantachie and Iuka soils on the bottoms.
On prairie clay the two problems are bearing and movement. Chalk residuum can be shallow, so a cut that looks routine hits rock-hard chalk needing a ripper or hammer while the ground two hundred feet away is soft clay, and trenching production swings wildly across a single run. Vertisol shrink-swell means pile design, foundation depth and pavement subgrade cannot be set from one boring, so push for a real boring spread across the array area. The upside is that these clays take lime well, so lime stabilization is often cheaper here than the undercut-and-stone approach the Delta forces on you. Clearing is a genuine line item, a mix of pasture, hardwood fence rows and planted pine, so grubbing and stump disposal volumes are real. Erosion control has to account for high suspended clay that will not drop out in a standard trap: plan longer detention and, where the spec allows it, flocculant.
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. Yes. Commercial civil sitework in Mississippi requires a Commercial Certificate of Responsibility from the Mississippi State Board of Contractors. Mississippi law makes it unlawful to contract or subcontract any portion of a public or private construction project equal to or exceeding $50,000 unless the contractor or subcontractor was duly licensed by the Board as of the date bids were submitted, so the license must be in hand before bid day, not at award. Applicants file a CPA reviewed or audited financial statement and hold the classification that matches the scope, and out of state firms must also be registered with the Mississippi Secretary of State.
Construction stormwater. Mississippi Department of Environmental Quality (MDEQ), Environmental Permits Division, issues the Large Construction Storm Water General Permit, permit number MSR10, covering construction that disturbs five or more acres. Coverage is obtained by filing a Large Construction Notice of Intent (LCNOI) at least 30 days before construction starts, with a Certificate of Good Standing from the Mississippi Secretary of State dated within the prior 12 months. The property owner and the prime contractor carry joint and several responsibility for compliance, which puts the SWPPP, inspections, and BMP maintenance squarely on the civil contractor on a solar site. 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 registered apprenticeship requirements apply through the Inflation Reduction Act to qualifying projects of 1 MW alternating current and larger when the owner claims the increased credit rate, so certified payroll and apprentice ratio tracking are standard on Mississippi utility-scale solar even on privately owned sites. Mississippi does not layer a state prevailing wage law on top of that for construction contracts, and it is a right to work state, so the wage determination that governs is the federal one written into the EPC contract. Contractors should confirm the specific wage determination and apprenticeship language in each solicitation rather than assuming none applies. 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.
