The Townsend Conservation Commission voted to issue a standard order of conditions with several special conditions for the Seba Road subdivision application filed by Belvedere Capital LLC (DEP 308-0729 / TWB2026-004).
Wayne, the applicant's engineer, told the commission the overall buffer zone on the property is about 150,000 square feet (roughly 3.5'3.75 acres) and that the planned impact within that buffer is roughly 24,000 square feet, or about 16% of the buffer. "There is 24,000 square feet of impact, which accounts for about 16% of the buffer zone," Wayne said, summarizing the filing's quantified impacts and the proposed stormwater controls.
Commissioners focused their review on stormwater sequencing, erosion-sediment controls, and on-site monitoring. Wayne described a three-cell detention basin with a sediment forebay, level spreaders to convert concentrated flows into sheet flow, and 24-inch culverts chosen to reduce concentrated velocities. He explained the design intent: "...the riprap apron and that first area in there is a sediment forebay," and that level spreaders and vegetation will transition flows to a more diffuse sheet flow to limit erosion.
The commission required the applicant's engineer to coordinate milestone events with the commission and to notify the commission prior to tree-flagging, clear-cutting, and installation of erosion controls. The body also added a condition that inspection reports be cc'd to the commission file and that conservation-jurisdiction placards be posted at the 35-foot vegetated buffer line at approximately 50-foot intervals. Commissioners noted the site will need a Stormwater Pollution Prevention Plan because the disturbance exceeds local thresholds for SWPPP filing.
A motion to issue the standard order of conditions with the drafted special conditions passed on a roll-call vote of the present members, after which the commission closed the hearing on the matter. The approved conditions call for milestone inspections, SWIP/SWPPP compliance, and specific signage and erosion-control measures to be tracked in inspection reports sent to the commission.
