Town of Mashpee Conservation Commission <br /> 16 Great Neck Road North <br /> Mashpee, MA 02649 <br /> NOI 15 Nehoiden Road, Matthew H. & Carmen F. Brogie. Proposed addition to single family home. <br /> (Representative: Strong Tree Engineering) (cont. 1.22) 43- <br /> 3394 <br /> Chair Cook recused himself due to a conflict due to applicant was a former client, and Vice Chair Thornbrugh <br /> presided over the hearing. Jack O'Leary presented the project on behalf of the Brogie family, who were unable to <br /> attend in person. The proposal involves construction of a previously approved but never built garage addition to the <br /> existing home at 15 Nehoiden Road, consisting of a two-story structure with a garage on the first floor and living space <br /> above. The property is located in an established neighborhood and contains no vegetated wetland resource areas, with <br /> the only applicable jurisdiction being land subject to coastal storm flowage. <br /> Mr. O'Leary explained that the garage foundation was anticipated at the time the house was originally <br /> constructed, with an existing foundation wall in place that would be removed and replaced with a new slab and <br /> foundation. The site is now mapped within a flood zone (Elevation 12), and the proposed design includes flood vents <br /> to meet current building code requirements. An existing gravel driveway would remain, a small porch would be <br /> removed and replaced with an at-grade bluestone patio, and utilities would largely remain unchanged, except for <br /> rerouting overhead electric service underground to accommodate the addition.No changes to the septic system were <br /> proposed. <br /> Commissioners' questions focused on construction details and materials, including confirmation that the patio <br /> would be bluestone set on granular material to allow drainage. More substantive discussion centered on Regulation 25, <br /> which requires case-by-case evaluation of expansions within flood zones and mandates two-to-one mitigation <br /> plantings for increases in building footprint or impervious surfaces. The Vice Chair and staff noted that floodplains are <br /> considered wetland resource areas under the local bylaw, and mitigation may be required to offset loss of flood storage <br /> capacity and cumulative impacts. <br /> The applicant's representative questioned how mitigation would apply given the existing gravel driveway and <br /> limited space for additional plantings, and indicated the applicant would likely seek a waiver from the mitigation <br /> requirement. Commissioners advised that any waiver request must address the criteria outlined in the bylaw, including <br /> the necessity of the waiver, the degree of relief sought, and whether compensatory measures would protect floodplain <br /> values. Additional information was requested regarding stormwater management,potential cumulative impacts, and <br /> review of Morris Flood Data Viewer projections as part of the floodplain analysis. <br /> With several outstanding issues identified, the applicant requested a continuance to February 19, 2026, to prepare <br /> a waiver request and revised materials. Conservation staff offered to assist the applicant in understanding waiver <br /> standards and submission requirements. <br /> MOTION: To continue the hearing to February 19, 2026 for 15 Nehoiden Road. <br /> Motion by: Sandi Godfrey Seconded by: Richard Sahl <br /> Vote: Motion passed by unanimous vote. <br /> (Sarah Thornbrugh, Paul Colombo, Sandi Godfrey, Seana Pitt, Richard Sahl) <br /> 8 <br />
