Complete civil packages for battery energy storage near Dryden, 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 Dryden in Tompkins County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
Dryden is the location of BR Caswell Road Solar, a NYSERDA Build Ready project advancing a 12.5 megawatt solar array and a 2.5 megawatt battery energy storage system on the former Ithaca North landfill at 557 Caswell Road. The town is served by the NYSEG Dryden, Dryden Tap and Etna substations and sits on Route 13 and Route 38 with straightforward heavy haul access from Interstate 81 at Cortland. The town board has adopted a solar payment in lieu of taxes law. Landfill siting means differential settlement, gas management and cap protection all govern pad and trench design.

Tompkins County spans the head of Cayuga Lake and the plateau on either side of it. Unlike the counties to the south, Erie and Langford soils are the two most extensive series, both formed in dense till with a fragipan generally 14 to 24 inches below grade, Erie somewhat poorly drained and Langford moderately well drained. Bath, Lordstown, Volusia and Mardin fill out the uplands, with Lordstown moderately deep over shale and siltstone. Valois soils occupy the gravelly kame terraces flanking Cayuga Lake and are deep and well drained. Howard and Chenango gravelly loams occupy valley outwash. Lansing and Conesus soils appear on the gentler calcareous till slopes north of Ithaca, and Hudson soils, formed in lacustrine silt and clay, occur near the lake and behave as low permeability, frost susceptible subgrade. Slopes into the Cayuga trough and its gorges are severe. Design frost depth is roughly 42 inches.
The Erie and Langford fragipan across most of the county means enclosure pads should be designed with upgradient curtain drains, an underdrained aggregate section and positive surface fall, and stormwater should be planned around detention rather than infiltration. Hudson lacustrine silt and clay near the lake is the worst case, frost susceptible and slow draining, and should be undercut and replaced or bridged with geogrid under the pad and access road. Valois and Howard terrace ground above the lake is the best subgrade available and should be favored where layout allows. Lordstown and Bath shoulder positions bring shale into trench depth, so cable, conduit and ground grid work needs rock provisions. Gorge and lakeshore proximity makes SWPPP review demanding, with tight disturbance limits and early stabilization expected. Brownfield work at the Cayuga site adds demolition coordination and existing subsurface utility conflicts.

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 no Tompkins County municipality appears on the statewide battery energy storage moratorium tracking with an active utility scale moratorium. The Town of Dryden has adopted a solar payment in lieu of taxes law, and the Town of Lansing planning board has held the TeraWulf application at the Cayuga site incomplete pending further submissions, so local review timing rather than prohibition is the schedule risk.
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.
