Complete civil packages for battery energy storage near Sheridan, NY: pad subgrade and mass grading, foundation excavation, access and crane pads, collection trenching, ductbank, SWPPP, and substation civil.
Backwell contracts complete civil site work packages for battery energy storage developers and EPCs building near Sheridan in Chautauqua County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Sheridan is a rural agricultural town on the lake plain between Dunkirk and Silver Creek, served by NY-20, NY-5, and I-90 exit 59, with a Norfolk Southern mainline crossing it and the Dunkirk area 230 kV and 115 kV buses close at hand. It carries no active battery storage moratorium as of September 2026, which distinguishes it from most of its neighbors and is the practical starting point for developers screening the county. Parcels are large and level, subgrade is silty and clayey lake plain soil with a seasonal high water table, and agricultural drain tile is widespread, so drainage survey and tile reconnection should be assumed.

Project details come from public filings and reporting and are listed to show where the work is. Backwell is not affiliated with these projects or their developers.
Chautauqua County runs from the Lake Erie shore to the crest of the Allegheny Plateau in about fifteen miles, and the change is abrupt. A narrow lake plain two to four miles wide carries Dunkirk, Canadice, and related silt loams and silty clay loams formed in glaciolacustrine deposits, level and somewhat poorly to poorly drained, with Chenango gravelly silt loams on the beach ridges and stream terraces. Behind the plain a wooded escarpment rises several hundred feet, cut by deeply incised ravines on Canadaway, Chautauqua, and Walnut creeks. Above it the upland carries Chautauqua, Langford, Erie, and Volusia series till soils, many with fragipans in the 18 to 36 inch range that perch water and create springs and seeps on the slopes. Bedrock is Devonian shale and siltstone of the Canadaway and Java groups, shallow in the ravine walls and along the upland ridges. The lake plain is the Concord grape belt, prime agricultural soil, which is itself a siting constraint.
Sites on the lake plain sit on level but wet silt and clay in prime farmland, so pads are built up on imported stone, agricultural drain tile is routinely encountered and has to be located and reconnected, and topsoil segregation and decompaction commitments frequently appear in permit conditions. Trenching is easy digging but needs dewatering and select bedding. Upland sites trade wet ground for slope and rock: fragipans perch water and produce seeps that have to be intercepted and outletted before a pad will hold, side hill cut and fill balances get tight quickly, and shale within a few feet of grade turns foundation excavation and deeper duct bank runs into hammer work. Access roads climbing the escarpment need switchback geometry and heavier stone sections to carry enclosure deliveries, and erosion control on those grades is the single largest stormwater exposure on the job.

Concrete is placed by our subcontractor partners under the same contract, so the foundations follow the earthwork without a separate award. We price the civil package as one scope under one contract, which gives the EPC a single point of responsibility for the civil critical path instead of managing separate clearing, earthwork, and underground subcontracts.
Battery storage in New York is governed by Section 1207 of the 2025 Fire Code of New York State, which the State Fire Prevention and Building Code Council adopted on July 25, 2025 with an effective date of December 31, 2025. Section 1207 carries material based on the 2023 edition of NFPA 855 and renumbers what the 2020 code placed at Section 1206. Systems must be listed to UL 9540. Large scale fire testing under UL 9540A, reported to and approved by the fire code official, is what permits reduced separation distances and quantities above the table limits, and a hazard mitigation analysis is required to exceed the maximum allowable quantity. Outdoor installations carry a ten foot clearance to lot lines, public ways, buildings, stored combustibles, and other exposure hazards, with ten feet of combustible vegetation cleared on each side. New York added a mandatory peer review at Section 1207.12 for systems above the Table 1207.5 quantities, covering the site plan, the emergency operations plan, and the UL 9540A report. Those provisions fix pad layout and access road geometry before any earthwork is priced.
Battery storage siting in New York runs on the Fire Code of New York State, which adopts the International Fire Code provisions for stationary energy storage, together with NFPA 855 and the UL 9540A test reporting the authority having jurisdiction will ask for. The civil consequences are set early and they are ours to build.
We build to the approved civil drawings and the fire code commentary that comes with the permit. We do not stamp the design.
Local law. As of September 2026 Chautauqua County carries more active battery storage moratoria than any other county in New York, with restrictions in Clymer, Mina, Westfield, Ellery, Dunkirk, Sherman, Poland, North Harmony, and the Village of Mayville, where a moratorium enacted in May 2026 runs to June 2027. Moratoria in Busti, Chautauqua, and Ripley have expired. Source: https://carina.energy/bess-moratoriums/new-york/
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. New York does not issue a statewide general contractor license for commercial construction. Licensing is handled locally, so individual cities, towns, and counties may require contractor registration or a local license, and a few trades are licensed at the state level, including asbestos handling and crane operation. Separately, contractors and subcontractors performing public work, and work covered by Article 8 of the Labor Law, must be registered with the New York State Department of Labor under its statewide contractor registry, which took effect December 30, 2024. Owners, EPCs, and integrators on battery storage projects will typically ask for that DOL registration number along with insurance and, where required, bonding.
Construction stormwater. SPDES General Permit for Stormwater Discharges from Construction Activity, permit number GP-0-25-001, issued by the New York State Department of Environmental Conservation. It took effect January 29, 2025, replacing GP-0-20-001, and runs through January 28, 2030. Coverage is triggered at one acre of soil disturbance, or less if part of a larger common plan, and requires a Notice of Intent plus a SWPPP prepared and implemented under the DEC design manual. Coverage under the prior permit did not carry over automatically, so active sites had to refile. Backwell carries the SWPPP scope, installs and maintains the controls, keeps the inspection log, and closes the permit out with final stabilization.
Prevailing wage. Standalone battery storage sits outside New York Labor Law Section 224-d. That section applies to a covered renewable energy system as defined in Public Service Law Section 66-p, and that definition lists generating technologies only, so energy storage is not included and Section 224-d contains no storage clause. Prevailing wage still reaches many storage projects by other routes. Labor Law Section 224-a expressly excludes an energy storage system with a capacity equal to or under five megawatts alternating current, which means a larger storage system on a privately contracted project that meets the public funds and cost tests can be covered. The Public Service Commission order of June 20, 2024 establishing the updated energy storage goal states that projects of one megawatt alternating current and larger will be subject to prevailing wage requirements, so incentivized projects carry it as a program condition rather than by statute. Storage co-located with a covered renewable generator follows that generator. Separately, contractors and subcontractors performing public work, and work covered by Article 8 of the Labor Law, must be registered with the New York State Department of Labor under the statewide contractor registry effective December 30, 2024. The applicable trigger should be confirmed project by project. Backwell produces certified payroll, pays the applicable wage determination, and supports apprenticeship labor-hour compliance.
