MEMORANDUM
DATE: July 31, 2013
TO: John Lavin
Division of Public Works
FROM: Jennifer Hughes, Conservation Administrator
SUBJECT: Barker Street Beaver Deceiver
Per our meeting on July 31, 2013, at the sewer easement behind 155 Barker Street, DPW is approved
to conduct maintenance and replacement, as needed, of the beaver deceiver located at the culvert
underneath the sewer easement impoundment. This deceiver was authorized by the Conservation
Commission in May of 2002 under an Emergency Certification Form. Section D, Special Conditions,
allowed for future "maintenance of the pipe by town officials and Beaver Solutions..." The following
additional conditions apply to the maintenance work:
• Removal of debris from the blocked pipe must be carefully conducted to prevent downstream
flooding; adverse impacts to the wildlife habitat located upstream and downstream, including
the created beaver habitat; and changes to the hydrology of the wetland resource area.
Breaching activities shall only occur at the beaver dam located on the sewer easement behind
155 Barker Street. Removal of debris will be done with a small excavator from upland areas
(on the sewer easement).
• All portions of the beaver deceiver requiring repair or replacement will be installed by Beaver
Solutions by hand within the resource area. If significant changes are required to the design or
installation method previously used, the applicant shall contact the Conservation Department
for approval.
• Approval of property owners must be obtained if necessary.
• Following maintenance work, the Conservation Department will be contacted for a post
construction inspection.
Please contact the Conservation Department with any questions or concerns.

Date: April 14, 2009
Subject: Beaver Dam Control
Telephone (978) 688-9574
Fax (978) 688-9575
I am concerned about the abnormal amount of water backed up within the wetlands area alongside
Route 114 is entering the Jasmine Sewer Pumping Station collection system and causing the pumps to
operate too much.
Notice the well-defined stream within the wetlands area alongside Route 114 near Jasmine Sewer
Pumping Station in these photographs. This satellite photo was taken some time ago before the
beavers had any influence on this area.
As you know this wetlands area is flooded due to the beaver dam, visible from the intersection of
Chestnut/Rae Street. The dam is backing up water to a point that it causing some infiltration problems
to occur within the Jasmine Sewer Pump Station on.
There is a sewer manhole located within this wetlands and visible from the road. If we can keep the
level of water within this area below the manhole, then infiltration can be reduced or eliminated all
together
Breaching the beaver dam and legally capturing the beavers would restore this area back to normal as
depicted on the photograph. At minimum, allow the use of beaver deceivers to be installed by a
professional people to lessen the flooding problem.
Please call me as soon as possible to discuss what action to take to restore this area back to normal and
eliminate infiltration to the Jasmine SPS, which will beneficial to the Town.
