John Sullivan, Town Engineer was present. Proposed 150 ft. extension of sewer on Branch Street, part of which falls within the buffer zone of an area protected by the Wetlands Protection Act. This will serve as a belated completion to the Branch Street sewer extension that was done in 1999. The sewer was not extended to 91 Branch Street. The Engineering Department and DPW have agreed to complete the extension as originally intended. All construction will take place within the right of way of Branch Street and will not r- disturb the nearby Baybrook Farm detention basin or the Back Bay Brook. The proposed sewer extension work is approximately 50 ft. away and is on the opposite side of the street from the Baybrook Farm detention basin and is approximately 180 ft. from Back Bay Brook. There is a 6-inch high granite curb between the road surface and the basin that will prevent any silt from reaching the basin. Siltation fabric will be placed beneath the catch basin grates during the installation. John said that the local Mansfield Wetland By-law allows for maintenance, repair or replacement of existing public ways. The Commission must be notified of any work. Michele recommends a Negative Determination be issued. Paul made the motion to accept the plan, dated 12-29-2005, and to issue a Negative 3 Determination. Passed 4-0. This request is for a second floor addition on an exiting house on Greenwood Lake. The existing foundation will be replaced because it is not to code and will not support the r- addition. The foundation is within in the same footprint of the present foundation. 0# ~ Colin would like hay bales behind the house on the lakeside. He wants to make sure any debris from the construction is picked up and disposed of properly. Mr. Brenneis told the Commission that he is restricted to 2 bedrooms. Mr. Brenneis will call Michele when the hay bales are in place so she can inspect and certify them. Michele recommends a Negative 3 Determination. Cindy made the motion to accept the plan with the revision for the new foundation and the placement of hay bales, to be certified by Michele and to issue a Negative 3 Determination. Passed 4-0. Perry DiMascio, applicant, and Ralph Maloon of RIM Engineering were present Resource Area Delineation of wetlands, east side only. Land falls within the Mansfield Water Protection District and an area of "Estimated Habitat of Rare Wildlife Species". r- Michele reviewed the wetland line on Friday, 2-24-2006. She explained that there had been a previous delineation but that it needed to be done again because the line is only good for 3 years. Colin explained to the abutters at the hearing that this filing is to delineate the wetland line, there is no project proposed at this time. When there is a project planned, the abutters will all be notified. The applicant is waiting for a letter from Natural Heritage. Carole wanted it noted in the minutes that they have to stay 100 ft. from any wetlands and that the Mansfield By-law supersedes Natural Heritage. Jerry arrived (7:10). Carole made the motion to accept the wetland line as shown on the plan dated 1-6-2006, for 18 & 19 Clementine Drive. Paul seconded. Passed 5-0. r- Shawn Carroll of CPR Pool, Inc. is the representative. ... r- This area is located within an "Estimated Habitat of Rare Wildlife Species" but there are no wetlands. The pool will be located on the exiting lawn, 10ft. from the deck. Colin asked what type of filtration system would be used. Mr. Carroll told the Commission that a sand filter with chlorine would be used. A dry well will be installed on the existing lawn within 3 ft. of the filter for the purpose ofbackwashing. Backwash will go into the dry well untreated. Cindy was concerned about the chlorine leaching out of the dry well into the Natural Heritage area. The Commission and Shawn do not think this will be a problem. Michele spoke to Jenna Garvey from Natural Heritage-they are not concerned about the pool (the pool will not be within 100 ft. of any wetlands). Paul wants the dimensions of the wetland line on the plan. Michele will meet Shawn to check the wetland line and Shawn will re-submit the plan with the wetland line added. She recommends an Order of Condition be issued. Colin told Shawn that if the line is less than 100 ft. he would have to come back for another hearing. r Cindy made the motion to accept the plan for 4 Castle Drive, and pending verification of the wetland line, that an Order of Conditions be issued. Carole seconded. Passed 5-0. Colin opened the hearing for 72 Williams Street. The Applicant was not present and the hearing will be continued to March 13,2006. The wetland line needs to be re-delineated. Proposed project is a 5-lot subdivision, Appaloosa Residential Compound, with pavement, grading, drainage and utilities within the 100 ft buffer of Bordering Vegetated Wetlands and an intermittent stream. Michele reviewed the wetland line and she asked the applicant to change the plan by moving the open space areas to abut the wetland areas. The plan now reflects these changes. The roadway is within the 25 ft. no touch area. r Carole wanted to know why this isn't a "limited project". Michele-a "limited project" is only when a wetland or other resource area is crossed to get to an upland area. Wetlands are a "limited project" because you are altering the area in order to cross. They are 5 ft. from the wetland area but will not be crossing this area. They are crossing an intermittent stream-it is not a "limited project" because you can cross a stream without interrupting the flow of water by the use of a box culvert. r Colin noted that the plans show the 25 ft. line only. The 50 ft. line needs to be put on the plan. Colin told the abutters at the hearing they would not be re-notified about the hearing on March 13th. Paul made the motion to continue the hearing to March 13th. Carole seconded. Passed 5-0. This site is a former gravel pit. By an order of the Bristol Superior Court, an attachment was placed on the site, liening the property. Mr. Walsh is the new owner and is in the process of addressing the court's decision by the creation of a swale in order to facilitate drainage. Loam & seeding is also planned in order to stabilize the site. r- Michele has not reviewed the wetland line and the hearing will be continued to the March 13 th hearing. Paul made the motion to continue the hearing until March 13th. Cindy seconded. Passed 5-0. The ANRAD for 33 Angelina Lane needs to be re-signed because of changes. The revised date was added to the plan and the Town of Mansfield Wetland Protection By- law Chapter 15 was added to the heading. Carole made the motion to accept the minutes of January 23, 2006. Paul seconded. Passed 5-0. Paul made the motion to accept the minutes of December 5, 2005. Jerry seconded. Passed 5-0. Colin made the motion to adjourn at 8:30. Jerry seconded. Next meeting will be March 13, 2006. ,~ . ~ ,"-'" r r a:~~~ (Gf~ Colin auldwell, Chair r.3 - ~7- 0 C:. Date r T
