Cr_,_ (� i�.; To Town Clerk 1�%U, OOi IM Wetlands Protection Act Hearing Continuation File: SE211-35 Department of Public Works Rt. 495 November 8, 1977 8:30 P.M. Commissioners: Frederick J. Rys, Paul F. Boyden, Doris Webb, Stuart Sweet DPW Reps: .Frank Burke, Dave Chareth, Buzz Gruhn Others: Marydee Flynn and Louis Andrews, GWSC; Margot Jellinek•; Alan Willis Mr. Rys told the DPW reps that the main reason for a continuation is to review the hydrologic studies. There was also a discrepancy with pipe size. The actual pipe size is a 72", although on one plan it shows 54". Q is quantity. Q will be 218 cfs, approximately 80 less than Mr. Willis is getting now. The orange portion is being picked up in a closed system and sent to the Rumford River. There will be 1/3 less water. Originally it was 300 cfs and now 220 cfs, based on a 50 year storm. That's the volume at that point, when the storm comes. Mrs. Webb asked the computation for a 100 -year storm. Mr. Gruhn answered that a 100 -year storm had not been calculated. Mr. Chareth said to add about 15%. Mr. Gruhn explained that the route of water from Forbes, Railroad., School St, remains the same. The drainage on School St, is a stream that gets into the swampy area. The State is still doing the same thing. They put a new system in &>jn School Street and discharge where old School St. meets new School St. The arrows show the direction of the flow into the pipe. Nothing will be added to the Rumford River. The water will get there faster through the closed system. Ramp B will turn into the system. Drainage on f the side leading from Ramp off South Main St. to Relocated Rt. 140 will eventually discharge into a ditch and up to a 48" pipe. Drainage along slope goes into sedimentation pool. Sedimentation pools are used during and after construction. 90% will runoff on paved ground and only 30% will runoff on grassed areas. Mr. Sweet and Mrs. Jellinek asked the total cubic feet of extra water into Rumford River after road is built and at what rate, plus considering the loss of a swamp which will alleviate some of the water. Mr. Gruhn replied 800 cfs total to the River. Mr. Willis stated that the topo as shown by the State is incorrect. Mr. Gruhn said the velocity to the River will be 3.76' per sec. which is considered slow for a channel. The water depth will be 6.3'. It is 2.5' now. The amount of water remains the same; it will only travel faster. Salting of roads and the overpass through the Great Woods were not discussed because they are separate issues. Mr. Chareth only said to Mrs. Flynn and Mr. Andrews that the DPW would like a physical committment from Mansfield. Mr. Willis asked about the aesthetics and errosion considerations and how the slopes will be cut. Mr. Chareth replied that after a year or two, the State returns with a planting contractor. Mrs. Webb asked what the Corps of Eng. and Dept, of Interior, Fish and Wildlife Division required from the DPW. Mr. Burke replied that the Fish & Wildlife Division required a dam in the Rumford River to help the fish in spawning. The hearing ended at 9:38 p.m. Wetlands Protection Act Hearing File: SE 211-36 Angelo's Sub Shop, Jay Howland and/or Brian McLaughlin 648 Pleasant Street, Brockton Purpose: Drainage of surface water. The hearing was held on November 8, 1977 at 8:00 p.m. at the Mansfield Town Hall. Mr. Jay Howland was present to answer any questions. Members from the Commission present were Frederick J. Rys, Chairman; Stuart Sweet, Doris Webb. Paul Boyden was present but had to leave the room to prevent conflict of interest. Mr. Howland explained that the building size is 32x40' and is located at 72 Copeland Drive. Septic plans have been approved by the Board of Health. Sinks will go into a 1,000 gallon grease pit. The drainage will be pitched to the rear of the property since the State will not allow drainage onto Rt. 140. Rt. 140 cannot hold anymore surface water. Abuttor, Mr. Souza, has given an easement right to drain water. Mr. Rys asked if there will be any salt. Mr. Howland replied that they will be using sand for the parking lot. Mrs. Jellinek suggested an oil trap located in the rear through which the drainage will go. The trap will collect oil before it drains into the swamp. She said only one will be needed and that they are not expensive. Mrs. Webb asked Mr. Howland if there will be a problem draining to one spot. r._ He replied no. There will be tar surround the building. The parking lot will be in front and the cars will drive to the rear, around the building and then exit. Hearing ended at 8:20 p.m.
