The purpose of this chapter is to minimize the exposure of citizens to the harmful physiological and psychological effects of excessive noise. The intent of the city council is to control the level of noise pollution in a manner which promotes commerce; the use, value, and enjoyment of property; sleep and repose; and the quality of the environment by establishing maximum environmental noise levels applicable within designated areas or zones of the city; to adopt appropriate exemptions to the provisions of this chapter to allow for the functioning of commercial business and the operation of construction and emergency equipment; and to declare certain noise-producing activities to be noise disturbances. (Ord. 1660 § 2, 2008).

8.14.020 Definitions.

As used in this chapter, the following terms shall have the following meanings. All technical terminology used in this chapter and not defined specifically herein shall be interpreted in conformance with the most recent definitions used by the American National Standards Institute (ANSI) or its successor body.

A. “A-weighted sound level” means the sound pressure level in decibels measured using the A-weighted network on a sound level meter as specified by the American National Standards Institute specification for sound level meters as now existing or as hereafter amended or modified. The level so read is designated dBA.

B. “Decibel (dB)” means a unit for measuring the volume of sound.

C. “District” means the land use zone to which the provisions of this chapter are applied. For the purposes of this chapter:

1. “Residential district” includes single- family (R-1), duplex (R-2) and multifamily (R-3) zones and the open space and parks (OSPA) zone;

2. “Business and commercial district” includes medium residential and neighborhood business (MR-NB), business (B-1), general commercial (C-1) zones, and the downtown zoning districts as they may be hereafter classified;

3. “Heavy commercial and industrial district” includes the heavy commercial (C-2) and industrial (M-1) zones.

D. “EDNA” means the environmental designation for noise abatement, being an area or zone (environment) within which maximum permissible noise levels are established.

1. Class A EDNA – Lands where human beings reside and sleep. Typically, Class A EDNA will be the following types of property used for human habitation, such as residential, multiple-family living accommodations, recreational and entertainment (e.g., camps, parks, camping facilities, and resorts).

2. Class B EDNA – Lands involving uses requiring protection against noise interference with speech, such as commercial living accommodations, dining establishments, motor vehicle services, retail services, banks and office buildings, miscellaneous commercial services, and property not used for human habitation.

3. Class C EDNA – Lands involving economic activities of such a nature that higher noise levels than experienced in other areas are normally to be anticipated. Persons working in these areas are normally covered by noise control regulations of the Department of Labor and Industries. Uses typical of Class A EDNA are generally not permitted within such areas.

E. “Emergency work” means work required to restore property to a safe condition following a public calamity, work required to protect persons or property from an immediate exposure to danger, or work by private or public utilities for providing or restoring immediately necessary utility services.

F. “Equipment” means any stationary or portable device or any part thereof capable of generating sound.

G. “Gross vehicle weight rating (GVWR)” means the value specified by the manufacturer as the recommended maximum loaded weight of a single vehicle.

H. “Motor vehicle” means any vehicle which is self-propelled, used primarily for transporting persons or property. Aircraft, watercraft, and vehicles used exclusively on stationary rails or tracks are not motor vehicles as that term is used herein. It includes motorcycles unless distinction is made in the context of use. It also includes self-propelled vehicles commonly known as all-terrain vehicles.

I. “Motorcycle” means any motor vehicle having a saddle for the use of the rider and designed to travel on not more than three wheels in contact with the ground; except that farm tractors and vehicles powered by engines of less than five horsepower shall not be included.

J. “Muffler” means a device consisting of a series of chambers or other mechanical designs for the purpose of receiving exhaust gas from an internal combustion engine and effective in reducing sound resulting therefrom.

K. “Noise” means the intensity, duration, and character of sounds, from any and all sources.

L. “Noise disturbance” means any sound which annoys, disturbs, or perturbs reasonable persons with normal sensitivities; or any sound which unreasonably injures or endangers the comfort, repose, health, hearing, peace, or safety of persons or animals.

M. “Person” means any individual, firm, association, partnership, corporation, or any other entity, public or private.

N. “Person responsible for the violation” means any person who is required by the applicable regulation to comply therewith, or who commits any act or omission which is a violation or causes or permits a violation to occur or remain upon property in the city, and includes but is not limited to owner(s), lessor(s), tenant(s), or other person(s) entitled to control, use and/or occupy property where a violation occurs.

O. “Property boundary” means the surveyed line at ground surface which separates the real property owned, rented, or leased by one or more persons from that owned, rented, or leased by another or others, and its vertical extension.

P. “Receiving property” means the real property within which sound originating from outside the property is received.

Q. “Race vehicle” means a motor vehicle not licensed for use on the public streets and/or which is used primarily for sanctioned or unsanctioned racing events.
