Owner/applicant: J and N Design and Build <br /> Project: Request to amend approve drainage plan <br /> John McGeogh- owner/builder, Bob Bibbo- surveyor, Tom Ryan- landscape architect, Edward <br /> Chang- Engineer <br /> Mr. McGeogh stated that he has provided more information regarding how the water will be <br /> directed to the system. He explained that they are now directed the downspouts directly to the <br /> system. In order to address the run off problems, they are proposing a few rain gardens to clean <br /> the run off before it reaches the system. Additionally, they are proposing to scrape off some of <br /> the top materials and bring in washed stone. They will also be adding some erosion controls on <br /> the ledge. <br /> Questions and comments from the commission: <br /> The commission stated that they are concerned that the system will not allow someone to <br /> observe the system and fix any problems. The commission stated that they need to feel <br /> comfortable with a feasible maintenance plan before they approve it. <br /> The commission asked the applicant to explain the differences in this proposed system vs. the <br /> approved system. Mr. McGeogh explained that the new system will significantly reduce the <br /> amount of dry wells needed for the site as well as a detention pond in the town right away. <br /> Additionally, the new system does only needs emergency overflows to the Town Drainage <br /> system. <br /> The commission asked for more details regarding the capacity that the drywells can contain. Dr. <br /> Chang explained the details of the design and its ability to contain the 100 year storm. <br /> The commission asked for more details regarding the wing walls. <br /> Motion to continue the hearing to 7/24/2017 at the applicant's request made by Mrs. Dohan and <br /> seconded by Mr. Wolk.
