[Adopted 12-4-2018]
Unless otherwise noted in this article, all site plan review requirements of this article shall apply to farm entertainment events.
Any number of low-impact events per year may be held at any time during weekend operation hours or weekday operation hours.
Farm entertainment events that generate noise greater than a low-impact event but less than the testing standard as measured at a testing location shall be limited to a maximum of 26 per year. The Planning board may specify a lower number of events per year for initial permits, which may be subject to future increases.
Parking lot construction need not comply with the site plan parking standards specified in Subsection 3.4.27 § 380-1.20B(8)(a). A parking area plan in compliance with § 240-5.1C to E of the Zoning Bylaw shall be submitted for review and approval.
Any proposed signs shall be shown on the site plan and must conform to § 240-5.2 of the Zoning Bylaw.
The applicant shall create and preserve recorded test results using approved test equipment at least once during each event and shall submit all such permit holder test results to the Planning Board upon request.
Other parties may submit other recorded test results if they wish.
Violations of the special regulations for farm events shall be addressed as follows:
A. 
First violation: written warning and 30 days to address problem.
B. 
Second violation: $100 fine, plus suspension of site plan permit for 30 days.
C. 
Third violation: $100 fine, plus suspension of site plan permit pending a public hearing before the Planning Board to consider permanent revocation of site plan permit.
As used in this article, the following terms shall have the meanings indicated:
AMBIENT SOUND LEVEL
The sound from all sources other than the particular sound of interest; also knows as the "background sound level." The ambient sound measurement (A-weighted sound level) is taken when the offending sound cannot be heard, or with the sound source shut off.
APPROVED TEST EQUIPMENT or ATE
A calibrated integrating sound level meter (SLM) capable of measuring and expressing noise levels under the sound measurement parameters. Any ATE must be self-calibrated or externally calibrated not more than five hours before each use. As of May 2018, an EXTECH Model 407736 SLM meets the ATE standards.
FARM ENTERTAINMENT EVENTS
The use of farm structures and grounds to host events on the farm property that bring visitors to the farm. Farm entertainment events shall not include those farming operations and activities for which no action in nuisance may be maintained under law pursuant to MGL c. 243, § 6, including, but not limited to, educational conferences, fundraisers, festivals, weddings, and any and all other personal recognition or special events.
LOW-IMPACT EVENTS
An event for which the sound level remains equal to or below 10 dBa above the ambient sound level as measured in accordance with sound measurement parameters at the testing location and that draws no more than a maximum number of cars as determined by the Planning Board at the time the permit is granted based on location and road conditions.
OTHER RECORDED TEST RESULTS
Recorded test results submitted to the Planning Board by a party other than the permit holder.
PERMIT HOLDER RECORDED TEST RESULTS
Recorded test results submitted to the Planning Board by the permit holder.
RECORDED TEST RESULTS
SMP test results from a testing location, which results have been preserved by internal ATE logging records, cell phone screen capture, or other independently verifiable means, providing a permanent record.
SOUND MEASUREMENT PARAMETERS or SMP
A numerical dBA level, accurate to one decimal point, derived from testing using approved test equipment at a testing location in accordance with American National Standard Institute (ANSI) standard S1.4 (1971, as updated) Type 2 (as updated), using all of the following parameters: (i) the dBA value shall be expressed in A-weighted decibels, (ii) the dBA value shall be measured using an RMS "slow" time constant, (iii) the dBA value shall be based on an "L50" noise percentile level (50% of measurement period) and (iv) the dBA value will reflect "Leq(1min)" (energy averaged noise level, one-minute interval). SMP measurements recorded shall be taken so as to provide a proper representation of the noise source. During SMP measurement, the microphone shall be positioned so as not to create any unnatural enhancement or diminution of the measured noise. A windscreen for the microphone shall be used when required. Traffic, aircraft and other transportation noise sources and other background noises shall not be considered in taking SMP measurements except where such background noise interferes with the primary noise being measured.
TESTING LOCATION
A location either (i) designated by the party making the noise complaint ("complainant"), which location is designated on real property owned by or leased to such complainant ("complainant location"); or (ii) within the public right-of-way within 10 feet of the owned or leased real property of the nearest abutter to the farm entertainment event, and designated by the permit holder. Each testing location shall be not less than two feet nor more than six feet above ground level.
TESTING STANDARD
Sound measurement parameters not in excess of 75.0 dBA.
WEEKDAY OPERATION HOURS
Monday, Tuesday, Wednesday, or Thursday evenings, 4:30 p.m. to 9:00 p.m. Holiday Monday: 10:30 a.m. to 9:00 p.m.
WEEKEND OPERATION HOURS
