Complete civil packages for utility solar in Yavapai County, Arizona: 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 Yavapai County, Arizona. We contract the complete civil package under one agreement, with Backwell superintendents and lead operators on site.
Yavapai County is in the APS service territory north of the Phoenix metro and carries transmission linking northern and central Arizona. Solar and storage development is being screened here, but no large utility-scale solar project in this county was confirmed in a source read for this page. Terrain is more varied than the low desert counties, which raises grading and drainage cost on any site that does move forward. Treat Yavapai as a watch market rather than a confirmed 2026 to 2028 construction market.
Central Arizona transition zone, the most varied ground of any county on this list. The Prescott area sits in granite country: Precambrian granitic batholith weathering to grus and forming the boulder outcrops of the Granite Dells, with shallow, coarse, gravelly soils and the Lynx series and similar loams in the drainages. North and west lie Chino Valley and the Big Chino Valley, broad basin fill valleys with limestone and basalt rimrock, and basalt mesas carrying Springerville clays and Cabezon soils, Springerville being a very fine, smectitic clay with high shrink swell and Cabezon being shallow over basalt. East is the Verde Valley, cut into the Verde Formation of lacustrine limestone, mudstone and evaporite including gypsum beds, with Anthony and Bridgeport soils on the Verde River terraces. Elevation runs from about 2,000 feet on the Hassayampa to over 7,000 feet on Mingus Mountain. The Verde River is perennial, which is rare in Arizona, and Granite Creek, Oak Creek and the Agua Fria carry seasonal and snowmelt flow.
Grading in granite country is rock work, not soil work: shallow soil over hard granite and corestone boulders means blasting or hammering for cuts, trenches and pile, and boulder handling is a real quantity. Grus makes good compacted fill but ravels and gullies quickly on exposed slopes. On the basalt mesas, Springerville type clays are the expansive soil problem in this county: they crack open dry, turn to grease when wet, and will not support haul traffic in the wet season, so plan select fill or lime treatment for any pad or road. In the Verde Valley the gypsum and evaporite beds in the Verde Formation mean sulfate attack risk on concrete and the possibility of solution features, so sulfate testing and sulfate resisting cement are warranted. Real precipitation, snow at Prescott and Chino Valley elevations, and steep terrain make erosion control a full program: slope tracking, mulch, seed, check dams, and a winter shutdown window in the higher country. Perennial and riparian reaches on the Verde carry a heavier Clean Water Act and Arizona Game and Fish review burden than the desert counties.
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. Arizona requires a contractor license issued by the Arizona Registrar of Contractors (ROC). For commercial civil sitework the relevant classification is the commercial A General Engineering license, which covers fixed works, streets and roads, power and utility plants and related infrastructure, and which also carries the scopes of the A-4 through A-19 subclassifications including A-5, excavating, grading and oil surfacing. A contractor may alternatively hold a specific A subclassification such as A-5 rather than the full A. Licensure requires documented trade experience, passing the Business Management exam and the applicable trade exam, and a license bond.
Construction stormwater. AZPDES Construction General Permit (CGP) for Stormwater, issued by the Arizona Department of Environmental Quality (ADEQ). Coverage is required for construction disturbing one acre or more, or less than one acre if part of a larger common plan of development or sale, and it also covers temporary concrete, asphalt and material plants set up exclusively for the permitted project. The operator files a Notice of Intent with ADEQ certifying that a Stormwater Pollution Prevention Plan has been developed and will be followed. 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 and larger that claim the full investment or production tax credit, so certified payroll is standard on utility-scale solar in Arizona. On top of that, Arizona has no state prevailing wage law for state or locally funded public works, and Arizona statute preempts local governments from adopting their own prevailing wage ordinances. In practice the wage determination governing an Arizona solar site comes from the federal IRA requirement or from the owner or EPC contract, not from a state schedule. Davis-Bacon also applies directly on federally funded or federally assisted work. 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.
