⚡ 285 W BOYLSTON ST

1. Site Access & Topography

The subject property, located at 285 W Boylston St, benefits from direct frontage on a major state highway (MA Route 110). This provides excellent public road access for both construction crews and equipment delivery. Based on aerial imagery review, W Boylston St is a two-lane paved road capable of handling heavy truck traffic, which is a significant advantage for logistics.

However, the site's historical and current land use as a quarry presents a major buildability risk. The topography is likely to be highly irregular, potentially featuring steep embankments, excavated pits, stockpiles of aggregate, and uneven, uncompacted surfaces. The parcel acreage discrepancy between county records (29.47 acres) and Regrid data (16.26 acres) also requires immediate clarification, as it impacts the usable area. While heavy equipment like transformers and battery containers can physically reach the site via the highway, their placement and movement within the parcel boundaries will be challenging. Extensive civil work, including significant grading, soil compaction, and the creation of stable pad-ready sites, will almost certainly be required. This will add considerable cost and time to the construction schedule.

Actionable Insight: A preliminary desktop topographical analysis using LiDAR data should be commissioned immediately to assess the severity of the terrain. A full geotechnical survey with soil borings will be a critical and mandatory step before any financial commitment is made to determine soil stability and the extent of required earthwork. Access appears to be direct from a public road, minimizing the risk of needing off-site access easements, but a title search is required to confirm no restrictive covenants or internal easements exist.

2. Environmental Constraints

The environmental profile of this site contains significant unknowns that represent both risks and potential opportunities. Key constraints are as follows:

• FEMA Flood Zone: The flood zone designation is currently Unknown. This is a critical data gap. Any portion of the site within a 100-year floodplain (Zone A/AE) would be undevelopable for critical infrastructure like a BESS or would require costly elevation measures, rendering it economically unviable. A FEMA FIRMette must be obtained as a first step.
• Wetlands: The presence of wetlands is Unknown. Given the disturbed nature of a quarry, man-made ponds, vernal pools, or emergent wetlands could exist. Massachusetts has stringent wetland protection regulations (Massachusetts Wetlands Protection Act) with significant buffer zone requirements (typically 100 feet). A desktop National Wetlands Inventory (NWI) screening is required, to be followed by a formal field wetland delineation to confirm the boundaries of any jurisdictional areas.
• Brownfield/Superfund Status: The presence of a Superfund site within two miles is noted but is not a direct concern unless there is contaminant plume migration. More importantly, the site's history as a quarry makes it a candidate for being classified as a brownfield due to potential contamination from machinery maintenance (hydrocarbons, solvents) or unauthorized dumping. This is a double-edged sword: it presents a cleanup liability risk that must be quantified via a Phase I Environmental Site Assessment (ESA). However, if it officially qualifies as a brownfield, the project could be eligible for the 10% IRA Brownfield Tax Credit Adder, which would significantly improve project economics.
• Protected Species & Pipelines: The site shows no critical habitat or protected areas, and no major pipelines are nearby. These are significant positive findings that de-risk the project from two common fatal flaws.

3. Grid Infrastructure & Interconnection

The site's proximity to robust grid infrastructure is its most compelling feature. The FITCH ROAD substation is located only 1.3 miles away and operates at a maximum voltage of 69 kV. This is an ideal voltage and distance for a utility-scale BESS project (e.g., >5 MW). A 1.3-mile 69 kV line extension (gen-tie) is technically feasible, likely following existing road rights-of-way.

For a smaller distribution-scale project (≤5MW), the goal would be to interconnect to a 13.8 kV (or similar) distribution feeder. It is highly probable that a three-phase distribution circuit originating from the FITCH ROAD substation runs along W Boylston St, directly adjacent to the parcel. This would be a much lower-cost interconnection point.

Recommendations & Estimates:

• Recommended IX Voltage: For a project >5MW, target a direct 69 kV interconnection at the FITCH ROAD substation. For a ≤5MW project, target a 13.8 kV distribution tap along W Boylston St.
• Interconnecting Utility: Requires Verification. The transmission line owner is listed as Fitchburg Gas and Electric (a Unitil company), but the local distribution provider could also be National Grid. This must be confirmed immediately.
• Cost & Timeline: A 69 kV interconnection could range from $2M - $5M and would enter the ISO New England (ISO-NE) queue, which is notoriously congested, suggesting a 36-60
