The majority of the lot will involve pulverizing the existing asphalt in place and the new pavement will be placed over it. The paving closer to the building will be removed and replaced. The project will also include other elements to capture stormwater flow and treat the runoff. New perimeter and interior curbing will be installed as well as new site lighting poles. Documentation Submitted: — Plans: C-101 "Existing Conditions Plan", C-111 "Site Preparation Plan", C-121 "Layout and Materials Plan", C-141 "Grading and Drainage Plan", and C-501 "Details P'; Prepared for: Takeda; Prepared by: Symmes Maini and McKee Associates (SMMA); Stamped and signed by: John C.

Ltd.; Prepared by: SMMA; Signed: 3/23/2021; John Hart, SMMA, and Brian Lawlor and Michael Allen, Takeda Pharmaceutical, presented before the Commission the request to repave the parking lot and associated roads of 500 Shire Way. Mr. Hart informed the Commission that there will be no increase in impervious areas, no trees and/or vegetation are to be removed, erosion control will be placed around the entire perimeter, and there will be minor chances to control runoff with improved curbing. The current schedule is to begin in the beginning of June 2021 and finish in the beginning of August. Questions from the Commission: • Is there erosion control at each of the outlets? The plan shows existing rip rap at some locations but not at the other outlets. • Has there been newly added area of impervious pavement in the cross hatch/upper left hand corner of the site plan? The entire area has been degraded and loaded with invasive material. There should be a condition for some type of wetland restoration from the edge of the parking lot to the wetland line. • Would like to see a plan for invasive management, including the removal of burning bush from the island. • Would like to see more signs for "no snow storage" along the edge of the parking areas. Responses from the Representative: • We are not planning to add new pipes. We could add rip rap at the other flare downs if it was a condition.
