The Southborough Conservation Commission on March 30 said it will wait for outstanding peer reviews before sending its formal comments on a proposed 48‑unit 40B development at 250 Turnpike.
Melissa (Conservation Agent) told commissioners she drafted a comment letter but wants to “hold off sending this to ZBA until Lucas Environmental's peer review comes back.” She said the civil peer review arrived the same day and that staff want time to incorporate reviewers' technical findings.
Why it matters: the commission flagged several site plan issues that bear on Wetlands Protection Act jurisdiction and long‑term mitigation. Staff reported that the erosion‑control layer is missing from the most recent plan set, changes removed grading and drainage easements previously shown, retaining walls may lack construction clearance called out by the civil reviewer, one previously proposed wetland replication area was removed in favor of a buffer‑zone mitigation approach, and some planting lists lack diversity.
Melissa urged the commission to hold comments so ZBA sees consolidated peer feedback instead of piecemeal critiques. She also raised technical concerns about an extended culvert crossing that no longer includes grated openings to admit light and moisture, which staff and reviewers worried could impair wildlife passage.
Commission discussion focused on verifying limits of work near wetlands, asking for permanent buffers (split‑rail fence and signage) where units abut the wetland edge, confirming distances between infiltration structures and wetland edges, and requiring a site‑specific invasive‑species management plan rather than relying on an unrelated contractor‑yard plan.
No formal motion to send the letter was made; commissioners agreed to delay transmittal until early next week, after staff have reviewed Howard/Stein‑Hudson civil comments and Lucas Environmental's peer review. Melissa said she will circulate the final letter to commissioners before submitting it to the ZBA.
Next steps: staff will incorporate peer reviewers' findings and finalize the comment letter; the commission will receive the letter before it is sent to the Zoning Board of Appeals.
