DEP 201-1129 BL 1086
NOI, 494 Lowell Street
Applicant: Robert Burge
Project: Raze and Rebuild of a single family dwelling within the 100-foot Buffer Zone
Documents Received: NOI application/plans/drainage (4-3-2019), Engineering Memo
(4/11/2019)
Chairman Hamilton read the engineering report into the record.
Mr. Rich Kirby presented before the Commission for raze and rebuild of a single family
dwelling. The existing house is 93 feet from the wetland boundary. The proposed house is
slightly larger than the existing dwelling but the project will be reducing impervious area by
about 10%. Impervious area will be reduced in the buffer zone by 10%. An infiltration system
is proposed in the southwest corner of the house where all stormwater runoff will be directed.
A trench drain is located in the driveway.
Mr. Langseth inquired about the possible directions of waterflow.
Mr. Kirby stated that they will review the proposed Swale.
An abutter, Mr. Der Avedisian, located at 481 Lowell Street, asked what happens when the
stormwater management system fails. Mr. Der Avedisian stated that the neighboring
properties which were recently developed all installed infiltration systems which failed over
the first year of occupancy. The infiltration systems were removed over time. The current
owners use sump pumps. The abutter stated that the property owners presented before a
Lexington board or committee. The water at the surrounding addresses flow onto his
driveway.
Mr. Kirby stated that since this specific property had to present before the Conservation
Commission, this specific infiltration system had to abide by the Town of Lexington
stormwater standards which has been approved by the Town's engineering department.
The Commission asked the Conservation Department to investigate the area.
On a motion by Mr. Beuttell and seconded by Ms. Dohan, the Commission voted 5-0 to close
the hearing.
7:16pm
DEP 201-1131 BL 1088
NOI, 39 Sherburne Road
Applicant: Leyne & Shannon, Inc.
Project: Raze and Rebuild of a single family dwelling within the 100-foot Buffer Zone
Documents Received: NOI application/plans/drainage (4-3-2019), Engineering Memo
(4/11/2019)
Mr. Brendan Leyne presented before the Commission. Mr. Leyne was before the Commission
as a requirement to file a new notice of intent for the changes during construction at 39
Sherburne Road. The new notice of intent is based on the final as-built plot plan. Mr. Leyne
stated that as a result of the changes a larger infiltration system was installed. Chairman
Hamilton reminded the applicant that if a future owner wishes to add another or different
sump pump, they will need to come before the Commission. This should be explicitly stated
in the Order of Conditions because the infiltration system cannot handle a larger sump pump
than the existing one.
On a motion by Mr. Langseth and seconded by Mr. Beuttell, the Commission voted 5-0 to
close the hearing.
7:25pm
DEP 201-1130 BL 1087
NOI, 140 Marrett Road
Applicant: The Manuel Baptise Estate
Project: Removal of fill within the 100 foot buffer zone and 200 foot riverfront area
Documents Received: NOI application/plans/stream stats (4-3-2019)
Mr. Rich Kirby presented before the Commission. Ms. Marion O'Shaughessy, the property
owner was in attendance.
Mr. Kirby stated that over the last few years the home owner and her relatives have been
storing and dumping fill onto the property, specifically on the rear lot of 140 Marrett Road.
140 Marrett Road directly abuts wetlands which are delineated along the property lines. The
lot additionally comes within the 200 foot riverfront area. The two resource area delineations
encapsulate most of the rear lot of 140 Marrett Road.
Mr. Kirby stated that the applicant is proposing to remove all fill and debris that has collected
on the property over time with the remaining exposed areas to be restored. The restoration
project will use conservation wildlife mix and New England wildflower mix. Closer to the
wetland they will plant New England Wetland seed mix in addition to erosion control seed
mix. Blueberry bushes are proposed to be planted on the wetland border.
Mr. Beuttell inquired whether FENO markers should be placed.
Mr. Kirby agreed that some sort of monument may be a good idea however the property was
recently surveyed.
The Commission discussed the possibility of installing 6 or so boulders along the 25 foot no
disturb zone.
Chairman Hamilton asked that after the wetlands are cleared of the dumped soil that the
wetland be re-delineated in the area where the fill was in or adjacent to the wetland.
On a motion by Mr. Langseth and seconded by Mr. Beuttell, the Commission voted 5-0 to
close the hearing.
