He stated the designs were finalized, essentially a filtration system within the right of way and a Stormsceptor unit at the end of Hartwell place have been reviewed and are acceptable to the engineering department. At this point the Conservation Commission has the same plan set as the Planning Board and they are looking to close the Hearing tonight which would enable the Planning Board to close at their next meeting. Mr. Hamilton stated that the only thing to keep them from closing tonight is that the engineering report states there are phosphorus reduction calculations that they have not yet received and this really has to be part of the record. Rich Kirby stated that the phosphorus reduction calculations have nothing to do with meeting the DEP standards for stormwater management or the Town standard for stormwater management. Paul Finger, Paul Finger Associates, presented before the Commission. He stated they have met the requirements that they were looking for. They are providing a filtration system. There are no standards to meet- it's just data to put in the file for additional information. Concerns of the Commission: - The Engineering report requested that the hearing remain open until the calculations are submitted. - Stormwater design on Hartwell Place - There was a one year rate that was not being met. These improvements are supposed to mitigate that. - On the water quality trench, does the liner go all the way around the bottom? - Why would you want saturated material underneath that lower pipe? - Bioretention soil mix - stay there forever or does it get changed? Responses of the Applicant: - They have a different version that does not have the Engineering Department's request that the hearing remain open, so they were not aware of that request. - Stormwater design and water quality trench on Hartwell Place was explained. - If they could have achieved that they would have. They did 5 test pits along the roadway. To be able to get pipes in there, they couldn't maintain the distance between the high ground water and the infiltration. The best they could do is the water quality trench. - Yes it wraps completely around and on the bottom. It overlaps on the top. - Don't have an answer for that. - Over a period of time, some improvements do have to be made. On a motion by Ms. Samuels and seconded by Mr. Langseth, the Commission voted 7-0 by roll call vote to continue the hearing until September 8, 2020 at the applicant's request, for the sole purpose of receiving the phosphorus reduction calculations. Record of vote as follows: Ruth Ladd—Aye Kevin Beuttell—Aye Alex Dohan—Aye David Langseth—Aye Holly Samuels —Aye Duke Bitsko —Aye Philip Hamilton—Aye On a motion by Ms. Samuels and seconded by Ms. Dohan, the Commission voted 7-0 by roll call to adjourn the meeting at 7:52 PM.
