Town of Lexington, MA
Noise Advisory Committee (NAC)
Minutes of Meeting, August 6, 2024
The meeting of the Noise Advisory Committee ("NAC") was held in person and on Zoom in the
Select Board Room of the Town Office Building on Tuesday August 6, 2024 at 7 PM. There
were no attendees online.
NAC Members Present: Barbara Katzenberg (BK), Chair, Sallye Bleiberg (SB), Benjamin Lees
(BL), Laura Rosen (LR), Elaine Rudell (ER), and Joe Pato (JP), Select Board Liaison
Guest: Jim Malloy (JM), Town Manager
Introduction and Administration
1. BK called the meeting to order at 7:01 PM
2. LR moved, ER seconded, and the NAC unanimously approved the minutes of July 2, 2024.
3. LR was assigned as clerk for this meeting.
Committee Business
1. SB and ER followed up on assignments from July 2nd to ask the police and health
departments, respectively, to share formal noise complaints with the NAC. The police
department has had about 40 complaints, but their tracking doesn't state details about the
type or place of the complaint or its resolution, just the date. The Health Department
records were not made available. JM suggested that a better approach would be to ask him
to reach out to the department heads to provide information to the NAC— he will follow up
with them.
2. JM updated the NAC on the status of the part-time Noise Enforcement Officer (NEO) being
hired by the town. The town HR director is awaiting a final request to place the ad from the
police department, which the police chief said would be ready in the next day or two. The
NEO position will be within the police dept but not a sworn police officer. All gas-powered
leaf-blower (GPLB) complaints will be submitted to them, and they will also circulate around
town to find violations. Construction complaints can be handled by the building
commissioner
3. JM reviewed the history of the NAC and bylaw update. The last NAC resigned in early 2023
after working hard on a previous bylaw update that limited GPLB use. Subsequently, there
was a construction project near Wilson Farm that was generating a lot of noise and
complaints. Building Commissioner Jim Kelly (JK) purchased a good noise meter to record
noise levels, but town staff were concerned that ambiguous text in the noise bylaw made it
difficult to enforce. They wanted to clarify this ambiguous language before the next
construction season to avoid a similar situation of many complaints around construction
projects. JM gathered an internal working group of individuals responsible for enforcing
noise bylaw to approach this:

Noise Bylaw Working Group (NBWG)
Jim Malloy Town Manager
Jim Kelly Building Commissioner
Joe Pato Select Board Member
Julie Krakower Zoning Administrator (at the time)
Tim Flaherty Fire Chief
Mike Mclean Police Chief
John Mazerall Police Captain
Abby McCabe Planning Director
Joann Belanger Health Director
Alicia McCartin Assistant Health Director
The NBWG went through the bylaw section by section and suggested revisions, but some
members were uncomfortable moving forward with these given the lack of a public NAC at
the time. To clarify language in the current bylaw as a minimum goal before the next
construction season, JP pulled some aspects of the NBWG's suggestions into a warrant
article that did go before Town Meeting on March 18, 2024.
The JNoise Article was in 2 parts:
A) Clarification of the bylaw, which passed
B) A proposal to defer implementation of the GPLB ban by a year that was requested by
landscapers, which failed by a significant margin, based on arguments that adequate
technology was already available
The March 18th bylaw revisions were also approved by the state Attorney General's office,
but just in the last couple of weeks, so the general code hasn't been updated online yet.
4. JM gave an example of a noise complaint received yesterday from the Fiske Common
condominium association. That property is 15 acres, and the landscaper is using GPLB. JM
explained to them the exemption for properties over 1 acre, which will be hard to clean in fall
with electric leaf blowers (LBs). The exemption over 1 acre is for wheeled, four-stroke
engines, which are not as loud and have less environmental impact than the two-stroke
engine backpack versions.
5. JM provided the NAC with a redlined version of the NBWG's proposed amendments vs. the
focused version recently approved by the Town Meeting, and the NAC reviewed the
differences. The biggest difference between them is the NBWG proposed decrease of the
maximum noise level allowed in residential areas from 85 to 80 A-weighted decibels (dbA),
maintaining 85 dbA only in commercial areas. The current bylaw just states that "noise
pollution" is considered a change of 10 dbA over ambient noise levels, but these are hard to
establish as they fluctuate.Another proposed change is that golf courses be exempt even
for the two-stroke engine backpack GPLBs. The challenge for the NAC will be attaining the
right balance between allowing people and the town to make improvements to their property
and neighbors' rights to peace and quiet. Everyone has a different level of noise tolerance,
and more people are working at home since pandemic

6. BK suggested that the NAC consider other ways to ameliorate the impact of noise, such as
having only a specified number of days of ledge work, or even to put neighbors up in hotels
during blasting. JM mentioned that another change in the recently approved bylaw
clarification was that a "credential" noise mitigation consultant must be engaged by building
contractors, which may allow enforcement of better noise barriers. Some areas in town
used a rented noise barrier system recently and there were no complaints, but these do not
work well on a sloped property, such as the project near Wilson Farm.
7. BK noted that vibration due to blasting was also an issue for the project near Wilson Farm,
which is not covered by noise law. JM clarified that vibration damage is covered by the state
blasting law, which is managed by the fire department. Contractors have to offer a pre- and
post-blast survey of neighboring houses. JM gave the example that his own house suffered
a crack in the foundation because of nearby work, and the contractor did mitigate the
damage since they had done a pre-blast survey, so they had verification that the blasting
working caused the damage. He emphasized that the town needs to get this information out
there so neighbors will allow the pre-blast surveys to be conducted in their homes.
8. The NAC has been reconstituted to bring a broader cross-section of the community together
to address the fundamental question of"What is too loud?" and what mitigation is
considered reasonable, both of which will require a lot of discussion and public debate of
conflicting views. ER mentioned that many landscapers are leaving the area due to the
requirement of using electric devices, which are expensive. This will leave a gap in lawn
maintenance services and allow contractors with electric devices to price gouge. JM said
the town purchased a bunch of electric equipment for landscaping companies to test, which
has been going on since last summer or fall. Some landscapers are putting gas-powered
generators on the back of their truck to recharge electric LBs throughout the day.
9. The NAC agreed it should hear directly from contractors about the issues they face in
complying with electric LB and construction noise regulations, as well as from town
residents. Jim Kelly can give the NAC contractor names. BK said she would like the NAC
to see where we are a year from now as to GPLBs and how people are adapting to the new
law. BK thinks the NAC should also review public health data saying that 80 dbA is too high
for general health issues, not just OSHA, including cardiovascular issues. We have to look
at the health literature seriously and propose an evidence-based limit.
The NAC should:
• Meet with people who served on the NBWG as a collective group —they can inform you
on what can and cannot be enforced
• Meet with landscapers and contractors
• Meet with the public health director and assistant public health director
• Meet with people in town who understand noise issues— Lexington has many experts
o E.g. employees at Lincoln Labs
o JP knows a sound engineer who used to be on the NAC
• Review other towns' bylaws and websites:
o Cambridge has a very good noise bylaw, with temporary construction noise
allowances, although this is a more urban example
o Needham and Wellsley are good comparators

10. JP noted that the NAC timeline is not pressing — "something may arise, but for now you have
the luxury to look into things". JM noted that the NAC does not have any immediate issues
to deal with right now. Once the town starts hard enforcement of the GPLB ban, then you
can see the change—e.g. see if contractors need to buy new equipment. The initial period
for a newly reformed committee is to gather information. Give the current bylaw an
opportunity to prove what it's doing and then see what else is needed.
11. The lack of a hard limit in the current bylaw makes it harder to enforce. 85 dbA is just a goal
—the only strict limit is 10 dbA over ambient", which is hard to measure. Ambient noise
levels change all the time. They need to be measured every hour for a day to get a sense of
the range, and then see if construction noise exceeds this. Now that there is a noise
mitigation plan requirement, the Building Commissioner could require contractors to put a
noise meter on their site 24/7 to measure the noise levels and that a temporary construction
wall be built around a site. Noise will then be measured outside of that at the property line.
A noise mitigation plan is required if construction noise will last more than 7 days.
12. The bylaw states that both landscapers and homeowners are subject to the fine imposed by
the GPLB ban. There was a lot of discussion about this, since the collection mechanism is
not there for the landscaper. Also, the town can fine the homeowner, but local courts will
throw it out if it is unpaid, as it will be seen as too minor an infraction. Enforcement might be
dictated based on how courts will handle it. State laws limit what municipalities can charge
for noncriminal disposition, and district courts will throw it out for being too minor. JM noted
that the previous NAC created a much more detailed noise bylaw, and that Cambridge has a
very good bylaw, especially re: construction noise. Some towns like Sturbridge and Weston
have no noise limit at all. Alicia did a lot of the work for the NBWG, including a table of
allowable limits. Mark Sandeen also pulled something together about health risks of noise.
Action items:
• JM will reach out to police, health, and building departments to get complaint information
forwarded to the NAC (during his last 3 weeks as Town Manager)
• JM will send NBWG summaries to BK
• If the NAC does not hear back from JM about the complaints, BK will let JP know and he
will follow up with the new Town Manager, who should be hired by the end of August
• BK will ask Joe Campbell, an MIT sound engineer, if he would speak to the NACE
• BK will forward 6 complaints received at the NAC contact email to Select Board office
• JP will ask the website manager to note that the NAC contact email is not a complaint
management email
• Once the NEO is hired, the NAC will recommend a centralize complaint form and
website link for these to go directly to the NEO
• The NAC will review noise mitigation steps being taken at the Meriam and Edgewood
construction site
The next meeting is September 3, 2024, at 7pm. SB moved, LR seconded, and BK adjourned
the meeting at 8:32 PM.
Respectfully submitted, Laura Rosen
