The Town Council finds and declares that:
Excessive noise is a serious hazard to the public health and welfare and quality of life in the Town.
Each person has a right to an environment reasonably free from noise which jeopardizes health or welfare or unnecessarily degrades the quality of life.
The purpose of this chapter is to establish standards for the control of noise pollution in the Town by setting maximum permissible sound levels for various activities, to protect the public health, safety and general welfare.
This chapter may be cited as the “Noise Control Ordinance of the Town of Westerly.”
Unless otherwise expressly stated or the context clearly indicates a different intention, the following terms shall have the meanings shown. Definitions of technical terms used shall be obtained from publications of acoustical terminology used by the American National Standards Institute (ANSI) or its successor body.
The sound level in decibels measured using the A-weighted network as specified in ANSI S1.4-1971 for sound level meters. The level is designated “dB(A)” or “dBA.”
Any and all activity necessary or incidental to the erection, assembly, alteration, installation, repair or equipping of buildings, roadways, infastructure, or utilities, including drilling, blasting, mining, land clearing, grading, excavating and filling.
A logarithmic and dimensionless unit of measure often used in describing the amplitude of sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micropascals (20 micronewtons per square meter).
Any dismantling, intentional destruction or removal of structures, utilities, public or private right-of-way surfaces, impervious surfaces, or similar property.
Work made necessary to restore property to a safe condition following a public calamity, work to restore public utilities, or work required to protect persons or property from imminent exposure to danger.
Gas-, propane- or diesel-powered engine designed to generate electricity outside the confines of a building.
Any area, a tract or parcel of land owned by or under the lawful control of one distinct ownership. Abutting platted lots under the same ownership shall be considered a lot. The lot line or boundary is an imaginary line at ground level which separates a lot and its vertical extension owned by one person from that owned by another.
Any motor vehicle having a saddle or seat for the use of the rider and designed to travel on not more than three wheels in contact with the ground. The term shall include motorized bicycles and motor scooters.

Measurement of sound.
Decibel measurements shall be made with a sound level meter, which shall be an instrument in good operating condition meeting the requirements of a Type I or Type II meter, as specified by ANSI Standard 1.4-1971. For purposes of this chapter, a sound level meter shall contain an A-weighted scale and both fast and slow meter response capability.
If the measurements are made with other instruments, the procedure shall be carried out in such a manner that the overall accuracy is at least that called for in ANSI Standard 1.4-1971 for Type II instruments.
When the location or distance prescribed in this chapter for measurement of sound is impractical or would provide misleading or inaccurate results, measurements may be taken at other locations or distances using appropriate correction factors specified in this chapter.
Procedures and tests required by this chapter and not specified herein shall be placed on file with the Town Clerk.
Council shall have the authority, consistent with this section, to grant sound variances from this chapter after public hearing.
Any person seeking a sound variance under this section shall file an application with Council. The application shall contain information which demonstrates that bringing the source of sound or activity for which the sound variance is sought into compliance with this chapter would constitute an unreasonable hardship on the applicant, on the community or on other persons.
All applications shall be subject to a fee of $50 per day if granted and, whether granted or denied, an amount sufficient to cover the cost of advertising and notification to all residents and property owners within 100 feet of the noise source. Advertisement shall be made at least once, seven days prior to the public hearing, in a newspaper of general circulation in the Town. Notification shall be by regular mail at least seven days prior to the public hearing.
In determining whether to grant or deny an application or revoke a variance previously granted, Council shall balance hardship to the applicant, the community and other persons if the sound variance is not allowed against the adverse impact on the health, safety and welfare of persons affected, the adverse impact on property affected, and any other adverse impact, if the sound variance is allowed. Applicants for sound variances and persons contesting sound variances may be required to submit any information that Council may reasonably require. In granting or denying an application or in revoking a sound variance previously granted, Council shall place on public file a copy of the decision and the reasons for granting, denying or revoking the sound variance.
Sound variances shall be granted by notice to the applicant containing all necessary conditions, including a time limit on the permitted activity. The sound variance shall not become effective until all conditions are agreed to by the applicant. Noncompliance with any condition of the sound variance shall terminate it and subject the person holding it to those provisions of this chapter regulating the source of sound or activity for which the sound variance was granted.
Determination of modification of a granted variance shall be made in accordance with the rules and procedures set forth in the section for original applications.
Any person who shall violate any provision of this chapter shall, upon conviction thereof, be punished for each violation as provided in Chapter 1, Article II, General Penalty. The continuation of a violation of any provision of this chapter shall constitute, for each day the violation is continued, a separate and distinct violation hereunder.
