Town of Mashpee Conservation Commission 16 Great Neck Road North Mashpee, MA 02649 He agreed to confirm whether the house is seasonal and evaluate whether occupancy would remain minimal until sewer becomes available. Sewer Timeline and Septic Requirements Chair Cook stated that, contrary to what the applicant was told, sewering in this area is not"months away" but rather years away. He emphasized: • The Commission cannot approve a house that would be left without a functional septic system. • If approved, a new septic system would likely be required before occupancy. Mitigation and Lawn Area Chair Cook also questioned whether the "lawn" area closest to the salt marsh could be converted to mitigation rather than turf. Mr. Dibb agreed that the plan could be revised to reduce lawn area. Nitrogen Loading Calculations Chair Cook questioned the value of nitrogen calculations that do not incorporate unknowns about the leach pit's construction or condition. Mr. Dibb explained that nitrogen calculations are based on flow, not system design, and that septic tanks themselves offer minimal nitrogen reduction. Staff Recommendations and Board of Health Clarifications Mr. McManus recommended: • Adding a cobble edge to the lower side of the pervious driveway. • Considering a catch basin for the primary driveway or converting it to pervious surface to reduce runoff toward Shoestring Bay. He then addressed the Board of Health issue: • He has just received a letter from the Board of Health stating that any new home must meet BOH standards, which includes requiring an IA system. • This contradicted the builder's earlier verbal representation that the existing pit could remain. Mr. McManus also described recent stormwater improvements along Mashpee Neck Road near Shoestring Bay, noting the importance of runoff reduction. Given unresolved questions, including flood-compliant foundation details, septic requirements, sewer timing, mitigation adjustments, and revised architectural plans—the Chair asked the applicant whether they wished to continue.
