Conservation commission asks engineer to clarify beaver-related wetland impacts for University Heights plan

RJP Engineering provided a follow-up letter with updated wetland-buffer calculations for the University Heights conceptual project. Commissioners said the packet shows "total wetland buffer impact, 5,000 square feet" and figures associated with specific lots; members pressed engineers to explain whether the applicant would use present-day wetland delineation or an older baseline altered by beaver activity.

"I would want them to personally... show what the true impact is and what they're gonna do if a beaver comes back," Sheena Gilbert, a member identified as representing the planning board, told the commission. Commissioners questioned whether the developer intends to remove or modify the beaver dam, how water levels will be managed year to year, and whether the planning board should require mitigation plans before approving development steps.

Commissioner Bob Barker moved that the commission draft a letter to RJP Engineering requesting clarification of their contingencies and intentions regarding the beaver dam and downstream impacts. The commission also voted to table any recommendation to the planning board until October while it seeks the developer's written response. Later the commission approved sending a letter advising that the wetland-buffer impacts appear to be within state DES parameters while explicitly flagging concerns about mitigation for the beaver-created water changes.

Commissioners emphasized the commission's role as a land-usage advisory body: they can advise planning and zoning bodies and request more up-to-date delineations and mitigation information, but they acknowledged limits on authority regarding private-property actions such as beaver removal.
