Town of Mashpee Conservation Commission <br /> 16 Great Neck Road North <br /> Mashpee, MA 02649 <br /> undermine footings and that steel framing or helical piles might be better alternatives to minimize the number <br /> of holes and provide greater resilience. <br /> The Commission determined it lacked sufficient information to render a decision. Key missing elements <br /> included: <br /> • A complete piling and footing plan, showing quantity, depth, material, and layout. <br /> • Details on scour protection and Velocity Zone compliance. <br /> • An alternatives analysis to minimize dune impacts and consider non-concrete materials for the ADA <br /> ramp. <br /> Because of these information gaps, the applicant requested a continuance, which the Commission granted. The <br /> project hearing will resume on November 13th, with revised materials due the Thursday prior. <br /> MOTION: To continue 252 Shore Drive Concert to November 13,2025. <br /> Motion by: Sarah Thornbrugh Seconded by: Sandi Godfrey <br /> Vote: Motion passed by unanimous vote. <br /> (Steven Coop, Sarah Thornbrugh, Paul Colombo, Sandi Godfrey, <br /> Seana Pitt, Richard Sahl) <br /> NOI 5 Deans Hollow Road,John & Seth Ann Lewis &Drolet.Proposed installation of <br /> Innovative alternative (I/A) septic system. (Representative: Cape & Islands Engineering. Inc.) 43- <br /> 3350 <br /> Representatives from Cape & Islands Engineering—Chuck Roland, Andrew Garraway, and Attorney Adam <br /> Brodsky—presented a proposal for property owners John Lewis and Beth Ann Drolet to install an <br /> innovative/alternative (I/A) denitrified MicroFAST septic system. The upgrade would replace the existing <br /> three-bedroom Title 5 system with a four-bedroom system, located within a Zone II wellhead protection area. <br /> The Board of Health(BOH) had previously approved a nitrogen aggregate, allowing the additional bedroom. <br /> Despite the increased flow, engineers emphasized that the new system would improve nitrogen removal and <br /> groundwater protection, reducing nitrogen levels from 15 ppm to about 11 ppm. <br /> Dual Filings and Regulatory Context <br /> Attorney Brodsky explained that two Notices of Intent (NOIs) were filed: <br /> 1. The first for this septic upgrade, under the previous flood zone and nitrogen regulations. <br /> 2. The second for a raise-and-replace project, filed under the newer standards. <br /> This filing was intended to preserve the property's four-bedroom nitrogen credit before the <br /> regulatory changes took effect. Commissioners acknowledged the unusual dual-filing approach but <br /> accepted it, noting that only one project would ultimately proceed once approvals were finalized. <br /> Nitrogen Offset Documentation <br /> Discussion centered on the nitrogen offset and BOH documentation. While the applicant confirmed that the <br /> BOH had approved and recorded the aggregate, the offset paperwork and location were missing from the <br /> filing. Commissioners stressed the importance of verifying that the credited offset land lay within the same <br /> 8 <br />
