The bank will be cut in only two places, creating an island of upland trees, in the attempt to create a replication area of 5000 sq. feet. Comm. Rhoads felt that the concept makes sense, and the applicant was so advised.

Dick felt it was most important with this plan to make sure that replication work gets folly into groundwater. The applicant will proceed with planning according to l the discussion. MOTION: To continue to 6-11 at 8:30 p.w. (O'Neill - Smith; all in favor) VOTED MAPLE ST. LOT (SARR0: Mr. Folkman explained that a screened -in porch will be built on this lot, with one footing in the buffer zone. No yard re- grading. Old footing will be hauled off site. Current structure will not be enlarged, but closed in. Comm. Cauldwell noted that more impervious surface would result. The consensus was that while the project is likely to have minor impact, review is triggered under the regulations. A request will be filed, and the site will be walked at 6:40 on 5 -14cZl, +MAY MEETING SCHEDULED: AT THE HIGH SCHOOL AT 7:00 MAY 14, PRIOR TO TOWN MEETING. s ALSO AT 7:00 P.M. MAY 21, PRIOR TO TOWN MEETING. ,WETLANDS PROTECTION ACT HEARING CONTINUATION: Bonwood /Jess Realty Trust - Kelli Green - SE211 -309 Mr. Folkman represented Banwood and Jess Realty, Sanford Engineering f representatives were present to answer questions on wildlife habitat and water quality issues. Letters from the commission dated last fall were used as the basis for additional information submitted. Mr. Maloon reviewed the civil engineering issues. The road has been designed close to the existing grade. Detention is about 1 1/2 feet over groundwater. This will require a waiver of some sort from the Planning board. The applicant will have to return when the issue is resolved. The commission asked about the amount of recharge possible, if retention is used rather than detention. Mr. Maloon stated that if detention is used, the Planning Board has a minimum of 3 1/2 feet over groundwater. Comm. Rhoads noted that lot 9 appears to be very tight in order to comply with Title V regulations and town regulations, and that the commission would need to see proof that those areas would work. Given the tight nature of the lots, Comm. Rhoads asked whether the applicant could consider returning with a shorter road system, thus reducing all impacts to wetlands, even if a waiver from Planning Board regulations regarding length of ctrl -de -sacs were necessary. The Sanford representative explained ,that trying to preserve trees will be difficult, since the area has to be lowered by two feet. Chairman Powers suggested that clear cutting is to be avoided if possible. Comm. Rhoads explained that if the ,species is consistent with wetland areas (i.e., red maple), then an effort can be (made to save it (hummock, etc.); but if the species is not a wetlands indicator or wetlands tolerant, the commision doesn't mandate that it be saved. The Sanford r`Qpresentative also expressed an opinion that a trickle channel may not be a good idea because water contact with the plants in the basin will be reduced. Comm. Rhoads raised water quality issues regarding the basis for some of the calculations performed. Curb miles of roadway have not been considered. Sanford maintains that refoval of nitrogen will be done by wetland vegetation. The basis for the ie" /year fort dowsing (nitrogen) is Logan Airport figures for precipitation. These are jttd�ment calls, based on the soils - selection process should be tied into the test pits on the site. Mention was made of a potential special condition limiting lawn size. Comm. Rhoads would like to see determination of current background level of nitrogen, and how it will change. Total amount of filling for the subdivision: 1450 sq. ft. Dick Lewis pointed out that runoff from lawn areas and back yards has not been addretsed in specific fashion. Runoff from back yards into wetlands has not been taken into account with regard to nitrate loading. There was a problem with MONDAY, MAY 7, 1350 -- PAGE 3 Swale as shown on plan: no details given. Density in close proximity to wetlands is the issue. Lot 2 is unbuildable at this time due to the amount of wetland present. Lot 10 also appears to be unbuildable, and no construction is currently proposed there. (The Unbuildable nature of these lots could change if the area is severed.) The commission asked whether the new lots have been recalculated, given the changes in wetlands lines. The plans must be changed to reflect the new wetlands calculations. The commission j raised the possibility of a special condition stating that no more than 5000 sq. feet of filling for the entire subdivision would be allowed. Folkman stated that his reaction would be clarified upon consultation with his attorney. Unpaved driveways as a special condition would not be acceptable to the developer. A drain area in the slope of the driveway might be more acceptable. Thomas Hamilton, 815 Maple St., last summer wrote the commission pointing out that no paved driveway was allowed at 819 Maple St., and suggesting that the same protection should be afforded to wetlands in 1 this new subdivision. The applicant requested an extension to after the Planning J Board meeting. MOTION: To continue to B:DO on June 25. (Rhoads - O'Neill; all in favor) VOTER WETLANDS PROTECTION ACT HEARING CONTINUATION: - SE211 =329 David Duhaime- -131 York Rd. The plan reviewed this evening was revised 5 -7 -90. The pit has been changed to a trench and reserve area. A stone filled trench is shown placed at the end of the driveway for runoff. Site walks showed a discrepancy of about 20 -30 feet between site and plans,'with slopes steeper than depicted. Potential erosion /sedimentation problems possible. A 30 foot back yard would be acceptable to the Duhaimes. Comm. Rhoads feels the issue is one of construction performance standards. The project will require double row of hay bales, well staked, and should be monitored on a regular basis. MOTION: To close the hearing.

The commission approved. j - -Green Acres, SE21l -131: re amended order based upon relocation of some of compensatory storage area. The applicant was required to submit a wetland replication plan by 4 -30; Dr. Carr's report has been submitted. Using the compensation area as wetland replication for entire project is a problem for commissioners; Dick will pull the file and review. - -MACC advocating no net loss of wetlands. Looking for support for that policy. Lists of things to avoid, minimize, mitigate. Dick will draft appropriate response with appropriate copies to appropriate parties. - -D. Graham has spoken to Dick regarding "areas of critical environmental concern" designation. A speaker on Canoe River Aquifer indicated willingness to speak at a commission and /or joint meeting with other town boards for support for nomination for such designation. Advantages to designation - grant money, etc. Committee has already voted to submit the designation. June 6, selectmen's meeting, would be a possible time for such a meeting. Dick will try to schedule. - -Dick walked Sweet's Pond, BMX track, etc. with Tom O'Leary as a follow -up to discussion regarding use of oxen. Tom is of the opinion that he could work both those sites and manage the sites using selective thinning on a no -cost basis to the town. White pine would be desirable for him, since he furnishes wood chips for composting. Dick has to check with town counsel regarding bidding process etc. He is an accredited forester. Dick will draft letter. Chairman Powers felt that a 3 public forum would be in order regardless of what town counsel says. Should the town profit from it in order to put the funds back into the land? 1 -- LIBRARY /DUILDING COMMITTEE. Mr. McCaffrie et al. want copies of discussion in the minutes: Cbmm. Cauldwell will supply names of those who want it. -- LANCHANSKI. Planning Board is about to pull its bond. Dick will draft a letter, giving time frames and deadlines.

Commissioners will check, and if necessary, send a letter. - -Re: TOWN MEETING ARTICLES 16 R 17: taking Sweet's Pond money and putting it into land acquisition /management fund.
