PUBLIC MEETING A. Public Comment — None IL A. PUBLIC HEARING Notice of Intent Edwin Snider RT — 1 Brock's Court (42.3.4 -84) SE48 -2834 Sitting Bennett, Erisman, LaFleur, Champoux, Topham Recused Documentation Representative Public Discussion (4:04) Golding Site plans, topographical maps, photos, MNH sign off letter, departmental reports, and correspondence. Mark Rits, Site Design Engineering — Prior to the site visit, dug test pits and deep -holes to address ground water questions: that letter was submitted Jan.5. One concern was the type of foundation and the 2 -foot to groundwater separation issue: a deep hole dug center of the foundation revealed standing water weeping at about 36" below grade and mottling at about 32 ". Bottom of footings will be at the top of the high ground water and do not anticipate significant dewatering. Three small test pits and auger holes upland of the wetland boundary found the wetland that were delineated on the property to the west is accurately delineated and consistent with fill and upland area. The site has been modified over time with the area that is lawn going back to the 1990s. Not currently anticipating dewatering; any dewatering would be through the stormwater system. Steven Cohen, Cohen & Cohen Law PC Kendra Kinsehert, for Marsh Fader — Pond created in early 1900s and was an extension of a previously wet area and was never lined; it does have a connection to ground water and does meet the requirements of a pond. The hydric soils are a good indication of wetland hydrology. Soil samples did have features indicating there is a valid hydric system in place. Have submitted letters addressing these concerns and that the delineation indicated on the plans is not accurate. Even if the delineation is correct; this project doesn't meet the regulations in regards to 2 -foot separation from high ground water. The pervious driveway and patio are in excess of 50% of the buffers and a waiver has not been requested for that. Cormac Collier, Executive Director Nantucket Land Council — He will reserve his comments to see the information to be presented. Asked if there is any dewatering plan, significant or not. Bennett — Test Pit Eight indicated no water other than in the driveway. Rits —That test pit showed standing water at about 75" after being open about an hour. Champoux — Asked what the protocol is for going from the fill point to the groundwater as opposed to an unfilled point to groundwater. He thinks that should be considered. Rits — Don't have a good handle on when and how much the lawn area was graded and build; it goes back 15 to 20 years. The pond on the abutting property edge is greater than 50 feet from the proposed work. Reviewed the history of disturbance of the pond and surrounding area dating back about 100 years. Hydric soil conditions extend roughly 50 feet from the pond much of which has been maintained as lawn. Our consultant doesn't feel this qualifies as a functioning wetland resource area. The water causing the hydric soils is moving into a deeper aquifer as shown by a couple of the pits. Bennett — Asked the size of the pool. Rits — The pool will be 5.5 to 6 -foot deep; the base will be sitting at groundwater level. Noted that the deep hole pits were done after a day of rain but not high level of rain. Working on revised waiver requests. Addressing the 50% of the 25 to 50, this lawn is a pre - existing alteration. Erisman — The current disturbed area would function better than a compacted driveway. Rits — Part of the NOI is to improve conditions in the buffers. Page 1 of 5 Staff Minutes for Tanuary 13, 2016, adopted Jan. 27 Kinschert —The application for the permit with the Building Department indicates the pool will be 7 feet deep; that needs to be addressed especially within the area of groundwater. Rits — The pool plans have been revised. Asked for a continuance. There was a site visit at the adjacent lot with the third -party consultant and applicant; still waiting for some of that information to come in. Department of Environmental Protection (DEP) guidance on sites filled recommends going from the top of native material, down; the disturbance here is very- old and the area has been heavily disturbed. It is difficult to determine when it would be considered no longer a disturbance but the condition of the site. Feels it is important to get all the information in and then discuss it; for example, the abutting property has a man -made pond that is over 100 years old. Suggested the neighbor submit a Request for Determination of Applicability on the pond boundaries.

Monitoring Reports — 10 Tautemo Way: The final report through an enforcement action. 4. Reports: a. CPC, Golding — Nothing to report b. NP &EDC, Bennett — Nothing to report c. Mosquito Control Committee, Erisman — Nothing to report 5. Commissioners Comment a. Golding — In regards to Brocks Court, Diana Lewis' letter claims the building was moved without a ConCom permit. Staff — That is true. He has talked to the Zoning Enforcement Officer and Building Commissioner about issuing a permit without checking whether or not it needs a ConCom permit and about taking action to ensure a ConCom permit is obtained. Stephen Cohen, Cohen & Cohen LP — Steve Butler, Building Commissioner, has assured that a Certificate of Occupancy would not be issued until that is resolved. 6. Administrator /Staff Reports a. In regards to jurisdiction over flood zones. He is trying to get an expert here to discuss that resource area; it doesn't seem to take into account precipitation causing a flood only water from a pond or ocean. If the standards are taken very literally, the installation of pool actually increases the flood storage capacity of an area if the pool is empty. Flood zones don't address ground water separation and infiltration. The only performance standard is not to significantly alter the flood zone's ability of water to flow during flooding. Would need to post a public hearing regulation changes in relation to flood zones and herbicides /pesticides. Erisman — If a pool is full during flooding, contaminated water is washed back into the system when water recede. Champoux — A pool doesn't affect the flow of the water. The issue seems to have more to do with groundwater flow and some infiltration. Further discussion about the possible affect of a treated, fresh- water pool on flood water.
