Planning board approves minor site‑plan modification at 9 Otis Street to accommodate National Grid requirements

The Westborough Planning Board voted April 2 to treat a set of adjustments to the approved site plan at 9 Otis Street as a minor modification and approved the change unanimously.

Vito Colonna of Cornerstone Engineering explained National Grid requested lower pavement elevations and additional setbacks from utility poles in a rear power‑line easement. To comply the applicant pulled back pavement in constrained areas, lowered grades beneath the power lines, and balanced cuts and fills by slightly raising a slab elevation for the building. Colonna said these changes reduced pavement by roughly 10,000 square feet and added riprap or erosion‑control fabric where steeper slopes required stabilization.

Planning staff asked that the approval condition reference the revised site plan date of 11/30/2021 revised 04/01/2024. A motion to determine the modification minor and to approve it subject to standard recording and plan‑date conditions passed 5–0.

The approval requires the applicant to record the decision with the Worcester Registry of Deeds before beginning authorized site activity and to submit proof of recording to the Planning Department.
