2. Reduced Retaining Wall Length: Following discussions with neighbor Mr. <br /> Bettencourt, a reduction of 34 feet has been agreed upon for the property <br /> wall. The remaining wall will incorporate drainage to prevent standing <br /> water. <br /> 3. Percolation Testing: Percolation test results have been submitted to the <br /> Commission. <br /> 4. Increased Pervious Surfaces: All driveways and walkways will be <br /> constructed from pervious materials. Additionally, all existing impervious <br /> areas will be removed and replaced with pervious materials. <br /> To address drainage concerns, Mr. Dibb proposed the installation of a bioretention area at the <br /> northwest comer of the lot. <br /> COMMISSIONERS COMMENTS <br /> Mr. Colombo expressed concern about the adequacy of the proposed shallow profile <br /> drywells in handling all projected roof runoff. He inquired if there's any information regarding <br /> the limitations of the system during specific storm events. Mr. Dibb confirmed the use of two <br /> drywells, one with six chambers and another with two. He acknowledged that currently,no <br /> analysis has been conducted to assess the system's performance during specific storm events. <br /> AGENT COMMENTS <br /> Mr. Kent sought clarification on the wall. He wanted to know if it existed or would be <br /> newly built and what information was needed from Mr. Bettencourt. It was confirmed that the <br /> wall currently does not exist. Additionally, Mr. Kent inquired about the status of the septic <br /> system permitting, particularly regarding the request to raise the system as per the original <br /> approval. Mr. Dibb expressed confidence that the Board of Health would approve the request. He <br /> confirmed that the building permit had already been obtained, but Mr. Kent requested <br /> verification of this approval. Further discussion followed on this topic. This revision clarifies the <br /> purpose of Mr. Kent's questions and improves the flow of information. <br /> The Agent recommends the Commissioners to deliberate. <br /> PUBLIC COMMENTS <br /> The applicant's neighbor, Mr. Bettencourt, supports the project. <br /> Motion made by Mr. Cook to close and issue including the approval of the waiver per <br /> Regulation 25-C-7-C and the project as proposed.
