7:54pm DEP 201-XXXX, BL XXXX NOI, 24 Constitution Road Owner/applicant: Tracy Kemp Project: Home addition Markus Pinney, Environmental Consultant and Peter Gammie, Project Engineer Mr. Pinney explained that the applicant is proposing to two build two additions to their existing home. In the rear of the property, there is a steep slope that drops off to a wetland. The proposed additions would be no closer to the wetlands than the existing home. Mr. Gammie stated that because of shallow ground water, they were limited as to what stormwater mitigation options they had. They have chose to propose a rain garden in the rear of the property. All of the roof run off from the existing house will make its way to the rain garden. There is an existing stormwater system that is no longer functioning and will be taken off line. Pervious pavers will be used for the driveway and patio. Mr. Hamilton entered the engineering report into the record. Questions and comments from the Commission: The commission asked why the wetlands line has changed since it was last reviewed in 2012. Mr. Pinney explained that the change is very obvious on site and he wants to schedule a site visit. The Commission agreed to visit the site on 4/1/17. The commission asked if the back patio was approved under the initial Order of Conditions. Mr. Pinney explained that it was not. The commission requested that the stormwater calculations be rerun to not include the patio in the existing conditions. The applicant agreed. The commission asked for some clarifying details regarding the rain garden. The commission asked the applicant to come with more details regarding what type of vegetation they are proposing for the rain garden. The commission stated that they were concerned because the condition of the rain garden will vary from wet to dry frequently. Mr. Pinney stated that he will do more research into appropriate vegetation. The commission asked that downspout overflows be added to the plans. The applicant agreed. Motion to continue the hearing to 4/4/17 at the applicant’s request made by Mr. Beuttell and seconded by Mr. Langseth. Vote: 5-0 in favor. CONTINUED MEETINGS/HEARINGS
