PRE/POST-HEARING AGENDA: • Presentation: Horsley Witten Chop Chaque Bog Conceptual Restoration Neal Price from Horsley Witten presented the results from the conceptual feasibility assessment for both Chop Chaque and Quashnet bogs. The purpose of the study was to see if it's possible to restore the bogs to wetlands, what the right approach would be, and what the cost would be. Given the water level, vegetation habitat types, and peat thickness, the Chop Chaque Bog should be able to support a habitat again. Most of the preferred alternative cost comes from removing the artificial sand to get to the peat. The low cost alternative involves less excavation while still achieving wetland restoration goals. Agent said we have a grant opportunity with the State's In Lieu Fee Program that would cover some, not all of the restoration. This is still at the conceptual level. Once we make a final determination, the next steps would be getting a final plan in place and getting permitting and construction in place. Mr. Colombo asked if there are any time constraints in making a decision. Ms. Cadoret said In Lieu Fee still has to do their review, so it is contingent on their timeline. Agent asked if we pursued the low cost alternative, does that prohibit any additional work if we received funding? Neal Price said it's not impossible, but far from ideal. Agent said a phased approach is another option. Neal Price presented the results from the Quashnet feasibility assessment. Here we want to restore a river system along with a wetland. We are still in the conceptual concept phase. Agent said there's not too muchto add, the primarygoal is to improve fish passage. This is funded separately from the Chop Chaque Bog.
