Members Present: Chairman Powers, Commissioners Cauldwell, O'Neill, Owens,
Poholek, Rhoads, Smith
The meeting was called to order at 7:30 p.m.
NEW BUSINESS:
The Electric Dept. is proposing to take down some trees on Maple St. and
have filed a Request for Determination. Consideration should be given to
replacing trees on the other side of the road, to help maintain the character of
the road. The commission can indicate its opinion in a memo to the Planning
Board regarding the scenic way hearing; the commission has no other objections.
Dick recommended sending a memo to the Board of Selectmen stating a preference
that the work to be done from the Bird Rd. side in order to avoid working within
buffer tone.
MOTION: To send a memo to selectmen indicating the commission's preference
to have the pole line brought up from the Bird Rd. side of the
site (explaining Commi4yon jurisdiction within the buffer :one);
and also indicating the commission's desire to exercise
responsibilities as defined in town charter section 5 -8 (p. 10),
by advocating tree replacement on the opposite side of the road in
order to preserve its scenic character. CC the Planning Board.
(Rhoads - Cauldwell; all in -favor) VOTED
In approximately the same location, New England Telephone proposes to
install an additional 6 -8 poles. The consensus of the commission is that New
England Telephone does riot meet the criteria to be exempted from filing a
Request for Determination.

Contracta+s asled about changing the timing of the culvert crossing. Two water
lines and sewer line have been relocated, and additional information has been
provided in response to letter sent in January requesting additional detail
about the culvert crossing. Backup pumps will be on site. There will be 3"
pumps on both sides of the area to be drained. The crossing will take about 1
1f2 weeks. There will be a beehive leaching pit, into which the discharge from
the pumps will be directed. A detail of the box culvert was also presented.
240 ft. of stream will tie temporarily altered. Piping is all within the
construction footprint. Two issues: (1).Does the commission accept this method
of crossing; (2) Is t)-se timing satisfactory? There is r+e currently no snow
cover, so spring melt`ng will not be an issue. The state representative in
charge of issuing the water quality certificate suggested that going beyond the
middle of March might be a problem. Dick recommended that the commission accept
the amendment as a modification of the plan which is an insubstantial change
with regard to the wetland; and give permission to do work at this time.
Compliance to date has been good. Sewer work on the road which was not included
in original plan will be done at same time and should be reviewed by the
commission.
MOTION: To accept the revisions to plan, and to grant permission for
work to proceed as soon as possible.
(Rhoads - Cauldwell; all in favor) VOTED

WETLANDS PROTECTION ACT HEARING CONTINUATION - SE211 -309
Keli Green subdivision f
Ralph Maloon presented a new plan (rev. date 2- 21 -91). Since previous
hearing the plan has been reviewed by the Planning Board and Engineering Dept.,
.who wanted greater height for groundwater recharge area. Lot lines have been .
added. According to Dick, new plans answer questions raised. Mr. Maloon
doesn't anticipate any further changes from the Planning Board. Engineering is
awaiting high groundwater mark in April. Comm. Rhoads has reviewed the storm
drain calculations and suggested that the infiltration rate needs
review /confirmation. Some performance standard could be established in the
Order to substantiate the infilration rate. All house lots will have to come
back for review, except possibly lot 4.
Comm. Owens, noting that the public has raised the issue of segmentation
before, asked whether that issue has that been addressed. The applicant
maintains that the area previously altered in Austin Farms was owned by Bonwood
Company, and that this wetland crossing is on property owned by Jess Realty
Trust. Dick feels that special conditions of the Order should also address this
particular issue.
MOTION: To close the hearing.
(Rhoads - Cauldwell; all in favor, Owens abstaining) VOTED
Regarding the compensation area for three Form A Maple St, lots (which was
shown on the plan), Dick recommends issuing an Enforcement Order mandating that
the work be done within one year (this construction season) compensating for
filling which occurred at 245 Winter St. and 795 and 807 Maple St.
MOTION: So moved.

WETLANDS PROTECTION ACT HEARING -
National Development Associates -- Grading P, construction of parking areas,
retaining walls, drainage within 100 ft. of wetlands - -9 -19 Hampshire St.
(lots 2 -3)
Gene Reilley, National Devt. Assoc., Duncan Wood, GZA. File Number has not
yet been officially received by the commission. Abutters have been notified.
Aerial photograph presented. Proposal includes mirror image 2 -story building,
half office, Half light manufacturing. Loading in the rear of each half of
building. The work within the buffer zone includes a retaining wall and
parking area. One corner of the existing building (to be demolished) is within
the 100 ft. buffer; none of the new building is. The purpose of the wall is to
raise the back end of parking lot, to create low point so water can be directed
and stored. Existing erosion controls on site will be replaced and /or restored.
Void subsurface storage system, using rocks. When the entire system is full,
water will back-up into two lower catch basins. An existing riprap pad will be
used as discharge point. Dick: the wetland line has not shifted. The concern
raised at a site plan meeting was that the need for an no oil /water separator,
due to the truck traffic at loading docks, etc. Me. Reilley agreed to address
this issue. The commission felt that it is appropriate for the commission
members to walk this site on their own. The applicant requested an Order at the
next meeting if at all possible.' -
MOTION: To continue to 3 -11 -91 at 8:00. //-

REQUEST FOR DETERMINATION OF APPLICABILITY
Stuart Sweet -- Installation of single - family home septic system piping and
pump within wetlands buffer zone--1805 West St.
Mr. Sweet explained that the project involved replacement of a cesspool
currently between house and lake. There are no options for a gravity 'type
System; a pump system is only alternative. Board of Health will wait to hear
from DEP before approving it. The project will take 2 -3 days. The plan was
done by Karl Drown. Excavated material will be removed immediately. The old
cesspool will remain as is for the time being.
MOTION: To close hearing.
(O'Neill - Poholek; all in favor) VOTED
MOTION: To issue a Neg. # #3 determination, with the agent being informed

REQUEST FOR DETERMINATION OF APPLICABILITY
Folkman/Zola Builders Inc. - -House & grading within wetlands buffer zone- -
lot 5, Rosewood Court (Maple St.)
Mr. Folkman and Mr. Zola were present. The wetland flags were located by
Dr. Carr. A septic system is proposed in front of the house. The house is
shown 70 ft. from the wetlands. The applicant submitted a letter, read into
the record, agreeing to dry well, as -built plan, and monitoring by the agent;
the garage has been removed, driveway relocated, and the hay bale line extended
in accordance with the agent's requests. The lot was staked today; Dick looked
at about 4:00 this afternoon. Dick's concern is that one wetland area was more
extensive than shown, and he recommended that the commission take a look.
Comms. Owens and Poholek felt that work is extensive enough to warrant a NOI.
Comms. O'Neill, Rhoads, CaUldwell, Smith, Powers felt RDA is sufficient, but
only if wetland line doesn't change as a result of site walk, to be held at 7:00
a.m. on 3 -4 -91.
MOTION: To continue to 3 -11 at 8:15.
(O'Neill - Poholek; all in favor) VOTED
SE211 -251 - REVISION REQUESTED
The applicant requested permission to modify the order to accommodate a
future attached garage, by pulling the house forward and changing the grading,
using a drop wall. The corner will be about 10 feet from wetlands. If the
commission agrees to this concept, the applicant will return with more detailed
grading plan. The limit of clearing line will also change.
Mr. Folkman requested a partial release from 211 -144 and a partial release
from lot 21 SE211 -288 (with loaming and seeding still to be done).
MOTION: To release lot 21 from SE211 -144 (but not from SE211 -288, because
of wort? remaining).
(Cauldwell - Rhoads; all in favor, Owens not present) VOTED
