Joe Lyons seconded.All in favor, motion passed. Status of Final Plan: -No implementation begun other than the limited shellfish propagation and WWTP preliminary design. - -JBCC shared facility proposal: October Town Meeting article for$250,000 towards study. Joe Lyons suggested the verbiage for the $250,000 towards the study should be something along the lines of"continue moving forward however we have to move forward to solve this pollution problem." The Selectman should define the purpose and scope of it so that it includes the words"JBCC study and the required review expenses for the approved wastewater plant."This will give the Selectmen the flexibility to deal with whatever consultants we need to have in regards to JBCC or implementing the plan as it is now written. GHD WWTP Preliminary Design Project: -Presentation by GHD of recommended municipal ("Site 4")treatment plan design and site plan. Anastasia Rudenko and Lenna Quackenbush gave an update on the design development of the Mashpee water resource recovery facility. (Presentation attached.) The 5 phases are divided into 4 potential construction stages. The phases are contingent on how the shellfish do. Future phases will be implemented if the shellfish do not do well. The preliminary site layout shows in Blue the buildings to be built in Phase 1, in Green the potential to expand, and in Yellow the effluent recharge beds with potential to increase.There will be further tests once the facility is operational, some parts may not be used in future stages. There are 2 entrances: 1. The current entrance to the transfer station. 2. Proposed construction entrance (temporary) which is required by DPW. There's a vegetative buffer around the entire facility. Full plants you can't see through as a visual buffer in addition to the current forest trees. MA DEP recommends a 50ft buffer. We have 150ft around all, increased to 200&300 where it's closest to residential properties. Multiple side by side comparisons of 200ft&500ft buffers with Southport, Cotuit Meadows, Stratford Ponds, New Seabury, Mashpee Village, Mashpee Commons, and Windchime Point.
