The Nantucket Conservation Commission on Jan. 23 asked the applicant for 3 Star Farm LLC to submit detailed grading sections and finished-grade drawings after commissioners and members of the public expressed concern about the volume of fill and multiple retaining walls proposed for the southern portion of the 76 Eel Point Road property (SC 483884).

Mark Ritz of Site Design Engineering, representing the applicant, described a proposed development that includes a main dwelling, pool, cabana, detached garage and retaining walls. “The proposed main dwelling has a finished floor elevation of 29 feet,” Ritz told the commission and said retaining walls would wrap portions of the proposed development area.

Multiple commissioners and members of the public pressed for clarity about how much material would be brought on site, where fill would be placed, and whether the proposed walls — including a four-foot retaining wall around much of the development area — would alter hydrology and increase runoff toward adjacent wetlands. One commissioner said the project would require significant topographic change and called the amount of fill “an inordinate amount of manipulation.”

After discussion, Commissioner Arjie “RJ” Turcotte moved that the applicant provide updated plans showing final grades, cross sections and details of retaining-wall construction and material volumes. The motion passed on a roll-call vote with the chair recused from the vote; the commission continued SC 483884 to Feb. 6 for submission and review of the requested information.

Staff told the public that the commission must evaluate the permit application on the materials submitted and that further public comment will be accepted when the application returns to the agenda. Staff also said supplemental materials submitted to the office will be included in the packet distributed to commissioners before the Feb. 6 meeting.
