8.32.020 Definitions –Designated
The following terms as used in this chapter are defined as follows:
A. "dBA" means the sound pressure level in decibels measured using the "A" weighting network on a sound level meter as specified in the American National Standards Institute Specifications S 1.4-1971 for sound level meters. A decibel is a unit of sound, based on a logarithmic scale, of the relation of the magnitude of a particular sound pressure to a standard reference pressure of twenty micro pascals.
B. "Emergency vehicle" means a motor vehicle used in response to a public calamity or to protect or aid persons or property in situations of danger or injury.
C. "Gross combination weight rating (GCWR)" means the value specified by the manufacturer as the loaded weight of a combination vehicle.
D. "Gross vehicle weight rating (GVWR)" means the value specified by the manufacturer as the loaded weight of a single vehicle.
E. "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 such vehicles powered by engines not to exceed five horsepower and farm tractors.
F. "Motor vehicle" means any vehicle which is self-propelled, used primarily for transporting persons or property upon public highways and required to be licensed under RCW 46.16.010. (Airplanes, watercraft and vehicles used exclusively on stationary rails or tracks are not motor vehicles as that term is used in this chapter.)
G. "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 noise resulting therefrom.
H. "New motor vehicle" means a motor vehicle manufactured after December 31, 1975, whose equitable or legal title has never been transferred to a person who, in good faith, purchases the new motor vehicle for purposes other than resale.
I. "Noise" means the intensity, duration and character of sounds, from any and all sources.
J. "Sound level" means a weighted sound pressure level measured by use of a sound level meter using an "A" weighted network and reported as dBA.
K. "Sound level meter" means a device which measures sound pressure levels and conforms to type one or type two as specified in the American National Standards Institute Specification S 1.4-1971.
L. "Watercraft" means any contrivance, excluding aircraft, used or capable of being used as a means of transportation or recreation on water.
(Ord. 4000 §2.2, 1976).

C. Studying the existing system of truck routes within the city; determining areas with sensitivity to sound and vibration which are impacted by trucks; recommending changes or modifications to the truck routes to minimize the sound and vibration impact on sensitive areas.
(Ord. 4000 §4.1, 1976).
8.32.060 Compliance by city departments
All city departments engaged in any activities which result or may result in the emission of noise shall comply with federal and state laws and regulations, as well as the provisions of this chapter, respecting the control of noise to the same extent that any person is subject to such laws and regulations.
