Call to Order:
J. Allen called the
meeting to order at 7:
Audience of Citizens:
There was no new business to take under consideration.
Determination of jurisdiction for application of Walter A. Tabor for a
subdivision of property and development of twelve residential building lots
Road at the intersection with Thompson Hill Road, Assessor’s Map 6, Lot 57 in a RA Zone
on 31.9 acres.
The Board received revised site plan for the Hunter’s Ridge subdivision. The revised plan
added a sedimentation chamber. Level spread
ers are to be built early in the
process. The plans for the level spreaders are not available. Corrections have been made to the site
chambers have been added
to the plan
and each lot has a rain garden.
J. Valente said, until
our Town engineer stating that the design of the detention basins will handle the
flows that are occurring there, he does
believe the Commission has enough information to make a
decision on jurisdiction. Town Engineer Thomas Fenton has not reviewed the
100 year storm event
analysis he recently received in order to make his report.
J. Valente said the Commission should look
for some agreement in writing from W. Tabor to extend the 35 day period for rendering a jurisdictional
ruling to the next regularly
Wetlands issue at 276 Route 66:
submitted a letter to the Commission dated August 9, 2011
has had a discussion with
Thibeault and they are in agreement with most of
the information he had previously submitted. They
are waiting for a reaction from the Commission and looking for remediation.
J. Valente has tried to speak with everyone concerned
. He couldn’t get to the site during the last rain
L. Buck, repr
esenting C. Hamilton, prepared plans for C. Hamilton and described how the first plan
directing the water down Hennequin Road dated May 2009 was rejected by the town.
J. Valente said the revised plan shows an 8” pipe reduced from 18” in the original pla

L. Buck informed C. Hamilton that if she wanted to really dry up the horse paddocks
the drain would
need to get down into the hardpan.
He each section
of the drain
started with an 8” pipe and then upon
examination, it became apparent that the permeability of the natural soil could not carry a significant
amount of the rainfall
That is why it is designed as a surface intercepting
trench as well as a groundwater intercepting t
rench. The pipe starts as a
8” pipe, then goes to a 12”,
15” and finally a 18” pipe at the outlet.
L. Buck said the amount of water flow is not increased at the
from when it was a swale
but the rate of flow is faster.
L. Buck was interested
where the water goes when it reaches the road at the catch basin where there
is a 24’’ inlet. Upon observation, he said there is a broad swale that gets down near the end of the lot
that dives into a rip rap channel.
J. Felice said that swale is overflow
ing onto the Sanford property. He claims that the 1,000 feet of pipe
on the Hamilton property has improved the water flow but with no regard to where the water goes.
Norm Thibeault, representing A. Lasage, said he cleaned out the swale frequently. He e
ntered into the
photographs from a recent rain event.
ossibility is to cap the pipe, reduce
and add rip rap as per J. Valente.
Two solutions will be tried: trying a restrictor plate at the pipe open
removing the stones at the end of the swale along Route 66.
will talk to C. Hamilton regarding removing stone at Route 66. J. Valente will contact the
DOT regarding the stone along Route 66 also.
On behalf of L. Sanford, J. Felice th
anked J. Valente for getting into this issue and there has been no
formal application before the Commission or a notice of violation and they appreciate the Board’s input.

vegetations within the upland review area:

group is coming close to

report when it comes out.
