I Town of Mashpee Conservation Commission 16 Great Neck Road North Mashpee, MA 02649 *NOTE: INDIVIDUAL HEARINGS WILL BE LIMITED TO 15 MINUTES IN LENGTH (More complex proposals may be granted additional time, if necessary,by the Chair) NOI 367 Mashpee Neck Road, Gary & Linda Oldham. Proposed Raze & Rebuild single-family dwelling with town sewer connection. (Representative: Cape & Islands Engineering.) (cont. 10.23 / 11.13) 43- 3372 Project Overview and Revisions (367 Mashpee Neck Road) The applicant's representative presented a substantially revised site plan responding to prior Commission concerns, particularly related to impacts within the 0-75 foot buffer zone and applicability of Regulation 25, Standard 6 (vertical walls within the A Zone). Key revisions included relocating the proposed house closer to Captain's Row and farther from the coastal resource area associated with Shoestring Bay, thereby moving the structure entirely out of the flood zone. The redesigned plan eliminates the previously proposed lower-level driveway and associated stone walls on the bay side of the property. That area will be regraded and restored to a more natural bank condition. A new gravel driveway is proposed to serve the garage from Captain's Row, while the existing driveway off Mashpee Neck Road will remain asphalt but narrowed by approximately two feet on each side to reduce impervious area. Overall, the revisions result in a net decrease of approximately 500 square feet of development within the 0-75 foot buffer zone and a total reduction of about 226 square feet of combined structure and impervious surface. Based on these reductions, the applicant asserted that mitigation and the previously requested waiver were no longer triggered. The house will include a walkout basement on the bay side, with limited retained access to a lower-level door. Some existing pavement will be removed, further contributing to buffer restoration. Flood Zone and Coastal Regulations (367 Mashpee Neck Road) Commissioners asked about FEMA and state exceedance mapping. The applicant explained that only a small comer of the existing house footprint had previously intersected exceedance areas, and that with the revised layout moving the house farther upland, those concerns no longer applied. Because the structure is now entirely outside the flood zone, Regulation 25, Standard 6 was stated to be inapplicable. Sewer, Septic, and Title 5 Considerations (367 Mashpee Neck Road) Extensive discussion focused on wastewater management during the interim period before Town sewer service becomes available. The property is currently served by a Title 5 system with a leaching pit and was recently confirmed to utilize a grinder pump. Town sewer service is anticipated to be physically available in the spring of 2028, with the Sewer Department reportedly allowing a two-year window for connection where sewer installation is imminent and funded. The applicant stated that the project team has been coordinating with both the Sewer Department and Board of Health and intends to meet all applicable requirements. Efforts are underway to ensure the future sewer stub is coordinated from Captain's Row rather than Mashpee Neck Road, minimizing future disturbance and avoiding the need for a separate Conservation Commission filing solely for sewer connection. Once sewer service is available, the existing septic components would be abandoned in accordance with Title 5 requirements. 5
