semitrailers, campers, tractors, go-carts, snowmobiles, all-terrain

NOISE INJURY
The condition resulting from any sound that:
A.
Could cause, or allow to cause injury to the

by-law, will be expressed in A-weighted decibels (dBA), obtained with
a Type I or II sound level meter as specified under American National
Standards Institute (ANSI) standards.
NOISE POLLUTION
The condition resulting when: a broadband sound source raises
the noise level by 10 or more dBA above the ambient noise; or a tonal
sound source raises its octave band noise level by three decibels
or more above the adjacent octave band levels. These threshold levels
are identical to those in the Massachusetts Division of Air Quality
Control (DAQC) Policy 90-001 (2001).

[Amended 6-1-2020 ATM
by Art. 27]
(i) Contractors are permitted to operate tools or equipment used in construction,

disturb a reasonably prudent person only on weekdays between the hours
of 7:00 a.m. and 5:00 p.m. and on Saturdays between the hours of 9:00
a.m. and 5:00 p.m. Such operation is not permitted on Sundays and
legal holidays.

boundary that would disturb a reasonably prudent person only on weekdays
between the hours of 7:00 a.m. and 9:00 p.m. and on Saturdays, Sundays
and legal holidays only between the hours of 9:00 a.m. and 5:00 p.m.
(iii)
In addition to the above restrictions, blasting and the use
of powered equipment used in the breaking of rock and pavement, including
but not limited to hydraulic or pneumatic hammers, by contractors
and residents is permitted on weekdays only between the hours of 9:00
a.m. and 5:00 p.m. and is not permitted on Saturdays, Sundays, and
legal holidays.
B. Commercial trash collection. The operation of commercial
trash compactors or collection of trash, rubbish, refuse or debris,
which generates excessive or unwarranted noise at any point of public
or common pass-by between the hours of 11:00 p.m. and 6:00 a.m. is
prohibited.
C. Commercial deliveries or pickups. Deliveries or pickups
for commercial or business purposes between 11:00 p.m. and 6:00 a.m.
are prohibited unless the noise level of such deliveries or pickups
in nearby residential areas does not cause excessive or unwarranted
noise.
D. Electronic devices and musical instruments. No person
owning, leasing or controlling the operation of any electronic device
or musical instrument shall willfully or negligently cause or permit
excessive or unwarranted noise.
E. Fixed plant equipment. Excessive or unwarranted noise

or otherwise in control of a motor vehicle will permit the sounding
of any horn, alarm or other signaling device for any period of time
exceeding 10 minutes. Automatic alarm systems must be programmed to
reset within 10 minutes and may not activate again within the next
60 minutes. A police officer observing any horn, alarm or other signaling
device that fails to comply with this section will direct an owner,
operator, renter or person in control of the vehicle to silence the
motor vehicle alarm. If, after making a reasonable attempt to contact
the vehicle owner, operator, renter or person in control of the vehicle
(or if that person refuses to comply), the officer may enter the vehicle
to shut off or otherwise disconnect the power source. If unsuccessful,
an authorized towing agency may be used to remove the motor vehicle
to an approved storage area. The registered owner of the motor vehicle
will be responsible for all reasonable costs, charges and expenses
incurred for the silencing of the alarm, removal and/or storage of
the motor vehicle.
G. Stationary engine run-up. Permitting, allowing or
causing generation of excessive or unwarranted noise at any point

(i) A noise mitigation plan shall be required prior to the issuance of
a building permit for construction projects in or adjacent to residentially
zoned areas where:
(a) The project entails rock removal with heavy machinery, including
ledge removal, rock pounding, rock crushing, rock drilling or rock
cutting (collectively defined as "ledge work"); and
(b) Ledge work activities are anticipated to take place on more than
seven days over the course of the project.
(ii) A noise mitigation plan required under this §
80-8 shall, at a minimum, require portable sound barriers, designed to reduce sound levels outside the barriers by at least 10 dB(A), surrounding and installed as close as practicable to the source of the noise. These barriers must reduce construction noise to prevent noise injury to Town residents. The objective of this bylaw is to keep maximum noise levels under 85 dB(A) at the property line.
(iii)
In the event that a building permit is issued under the assumption that none of the §
80-8 provisions apply, and it is discovered that such provisions do apply after the project begins, then no ledge work shall begin or continue until a noise mitigation plan is submitted and accepted in accordance with §
80-8(ii).
(iv) In the event that the builder does not submit or follow a specified noise plan, whether by using inadequate barriers, poor barrier installation, poor maintenance, failure to move them to a new work area on site, or any other problem, then work must cease until the issue is corrected and a penalty of $50 per day may be assessed in accordance with provisions of §
80-7 for any days that ledge work took place without a plan, or not in accordance with a submitted plan.
(v) In addition to the general enforcement provisions of Chapter
80, the Building Department in conjunction with the Public Health Department shall have the power to enforce this section.

be available at the office of the Select Board or its designee. The
following criteria shall be considered when deciding whether to issue
a special permit:
[Amended 3-27-2019 ATM by Art. 34]

guidelines defining the criteria to be considered and the procedures
to be followed in applying for a special permit.
[Amended 3-27-2019 ATM by Art. 34]

in which the offending sound source is located. Renewal of a special
permit shall be up to three years. Any special permit issued to the
applicant shall contain all necessary conditions to ensure minimum
disturbance to the adjoining residences.
D. Legal notice of the time and place of said hearing
shall be given by the Select Board, at the expense of the applicant,

such notice in a conspicuous place in the Lexington Town Hall for
a period of not less than 14 days before the day of such hearing,

of existing Town of Lexington by-laws or Commonwealth of Massachusetts
laws.

The Select Board, or its designees, may promulgate,
