Complete civil packages for battery energy storage near Herkimer, 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 Herkimer in Herkimer County, New York. One contract covers site preparation through final stabilization, with Backwell field leadership on site.
The Village of Herkimer sits at Thruway exit 30 where NY 5, 28 and 5S meet the Erie Canal and the CSX mainline, which makes it the best heavy haul and rail transfer point in the county. West Canada Creek enters the Mohawk here and has built alluvial fan ground that drains better than the surrounding lake plain. Local 115 kV service runs on the Inghams and Valley lines that already carry the Fairfield Wind project. Any pad placed on the valley floor sits in floodplain with a shallow water table, so fill volume, undercut and stormwater design carry the civil scope.

The Mohawk River corridor through Frankfort, Ilion, Mohawk, Herkimer and Little Falls is a narrow floodplain and lake plain carrying Hudson, Rhinebeck and Madalin silts and clays, Ilion soils in the depressions and Herkimer series soils on the alluvial fans built by West Canada Creek and the smaller tributaries. South of the river the plateau shoulder carries Palatine and Mohawk soils formed in dark shale till, with shale bedrock commonly between twenty and forty inches. North of the river the ground climbs quickly into the Adirondack foothills, where Bice, Worth and Camroden till give way to Berkshire, Tunbridge and shallow Lyman soils over Precambrian gneiss, with Lyman running less than twenty inches to rock. Outwash terraces along West Canada Creek carry Colton and Adams sands. The Little Falls gorge exposes hard gneiss at the surface and is the clearest marker of how quickly rock rises north and east of the valley floor.
A Herkimer County site sits in one of two very different civil problems. On the valley floor the work is soft ground: undercut of lacustrine silt and clay, geotextile separation, imported structural fill under enclosure and transformer pads, dewatering in collection and auxiliary trench, and floodplain constraints that push finished pad elevation up and add fill volume. On the shale shoulder and in the northern foothills the work is rock: Palatine, Tunbridge and Lyman profiles put competent material within a few feet of grade, so foundation excavation, cable trench and grounding conductor installation should carry hammer, rock trencher and blasting provisions, and access road subbase can often be won on site. Access roads into the foothills need heavier crown and ditching for spring runoff, and the construction window north of the river is materially shorter than it is in the valley. Stormwater controls should assume erodible silt on the valley sites and steep short slopes on the upland sites.

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. The Town of Frankfort battery storage moratorium was recorded as lifted and the Town of German Flatts moratorium as under review as of September 2026. In the Adirondack Park portion of the county the Town of Salisbury and the Town of Webb have adopted moratoriums.
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.
