of TMs s,s z. Aannin Board c� 16 Great Neck Road North .wlashpee, Aassachusetts 02649 Some comments reflect changes to the western property line; a retaining wall and guard rail have been added next to the drainage basin. Slopes were reduced in those areas to 3:1, which is relatively gentle, and more manageable to stabilize with less erosion concerns. The roadway was regraded to 5% slope. The parking areas were confirmed to be 4% or less, as suggested in the peer review comments. The bylaw does not allow Cape Cod berm to be used for curbing, so precast concrete is used throughout the site. The islands at the end of the aisles increased to have 5ft. radius curbing. Delivery access was looked at. Right now, they are proposing incoming deliveries enter from the Rt. 28 curb cut and a striped area will be added to assist with truck maneuvering to that area, which will cut delivery traffic on Shellback Way. The trucks would still utilize Shellback Way to exit the site. This cuts the usage on Shellback Way for deliveries in half. There are two items in the zoning section, one being the parking lot required to have a 1:5 ratio of landscaping to parking area. They previously proposed 1:8, with the change to the islands, the ratio is closer to 1:7. It does not meet the threshold standard, it does allow for the permit granting authority to have alternatives based on the shape and impacts to the site. They would still seek a small piece of relief. This configuration currently allows for 14ft. and 15ft. They are trading off to get the parking away from property lines. Parking is required to be 1 Oft. away in a natural setting. The permit granting could allow less than 1 Oft. There is a wall in both areas, but in both areas providing at least 1 Oft. However, between the parking lot and the wall, with a couple extra feet and the wall, they believe they met that buffer zone requirement as well. Ms. Waygan asked about the porous parking spaces. It was answered that a method to reduce runoff was offered by the Cape Cod Commission. They wouldn't add that material to a drive aisle, as they clot with sand easier. It is not necessarily a requirement, but it was something we could provide in those spaces. Keep in mind, the site has 30ft. separation to ground water. Jean Christy, Consulting Board Engineer commented she is usually in favor of porous pavement, but within a commercial site may not be the best application. It will work for about a year or two and then it stops working and acts like regular pavement, and runoff will go into the rest of the drainage system, furthermore, she is unsure if this drainage can accommodate for that. Mr. Tobin stated if this is unreliable and poses future maintenance issues it may be more cost effective for the applicant to remove that from the plan. 3
