A. The purpose of this chapter is to minimize the exposure of the citizens of the city of Shoreline to the physiological and psychological dangers of excessive noise and to protect, promote, and preserve the public health, safety, and general welfare. It is the express intent of the city council to control the level of noise in a manner which promotes commerce; the use, value and enjoyment of property; sleep and repose; and the quality of the environment.
B. In determining a violation of this chapter, the content of the sound shall not be considered.
C. This chapter is established in conformance with Chapter 70.107 RCW, Noise Control; Chapter 173-58 WAC, Sound Level Measurement Procedures; Chapter 173-60 WAC, Maximum Environmental Noise Levels; and Chapter 173-62 WAC, Motor Vehicle Noise Performance Standards, as amended from time to time.
D. Nothing herein shall be construed to limit or prohibit different or more restrictive hours for any activity authorized under a permit issued under any other chapter of this code as provided for in that chapter. [Ord. 818 § 1 (Exh. A), 2018]
As used in this chapter, the following terms shall have the meanings set forth in this section:
A. “Construction” means any site preparation, including blasting or pile driving, assembly, erection, demolition, substantial repair, alteration or similar action on private or public property, buildings, structures, or utilities.
B. “dBA” means the sound level measured in decibels, using the A-weighted network on a sound level meter.
C. “EDNA” means environmental designation for noise abatement, which is an area or zone within which maximum permissible noise levels are established. EDNA classifications include the following zones as set forth in the city Unified Development Code, SMC Title 20, at SMC 20.40.20:
1. Class A EDNA: Residential zones and mixed-use residential zones;
2. Class B EDNA: Nonresidential zones;
3. Class C EDNA: Industrial land use zones.
D. “Emergency work” means work necessary to restore property to a safe condition following a public calamity, work required to protect persons or property from imminent exposure to danger, or work by private or public utilities to provide or restore immediately necessary utility service.
E. “Holidays” means the “legal holidays” set forth in RCW 1.15.050, as it may be amended from time to time.
F. “Motor vehicle” means any vehicle that is self-propelled, used primarily for transporting persons or property upon public highways, and required to be licensed under RCW 46.16.010. Aircraft, watercraft, and vehicles used exclusively on stationary rails or tracks are not “motor vehicles” as the term is used herein.
G. “Noise” means the intensity, duration, and character of sounds from any and all sources.
H. “Permitting authority” means the director, or designee, of the city department that issues the permit, such as the department of community and economic development, department of public works, and the department of parks, recreation, and cultural resources.

M. “Weekday” means any day, Monday through Friday, which is not a legal holiday.
N. “Weekend” means the days of Saturday, Sunday, and any legal holiday. [Ord. 818 § 1 (Exh. A), 2018]
A. Sound Level Meter. The use of a sound level meter may not be required to verify all noise violations such as public disturbance noises which may be discrete and/or intermittent and, therefore, not measurable at the time of the occurrence. If the measurement of sound is made with a sound level meter, the instrument shall be in good operating condition and shall meet the requirement for a Type I or Type II instrument, as described in the most current American National Standards Institute Specifications.
B. Location of Measurement. Unless otherwise specified in this chapter, the point of measurement shall be at the property boundary of the receiving property or anywhere within it.
C. Multiple EDNAs. When the receiving property lies within more than one EDNA, the maximum permissible environmental noise levels shall be determined by the most sensitive EDNA. [Ord. 818 § 1 (Exh. A), 2018]
A. Maximum Noise Levels. No person shall cause or permit sound to intrude into the real property of another person that exceeds the maximum permissible environmental noise levels established by this section. For sound sources located within the city, the maximum permissible environmental noise levels shall be as follows:
Table 1. Maximum Permissible Environmental Noise Levels
Class A (dBA)
Class B (dBA)
Class C (dBA)
7 a.m.–10 p.m. Weekdays
9 a.m.–10 p.m. Weekends
10 p.m.–7 a.m. Weekdays
10 p.m.–9 a.m.
B. Deviations. The following deviations from the maximum permissible environmental noise levels set forth in Table 1 of this section are permitted:
1. At any hour of the day or night, the applicable maximum permissible noise levels may be exceeded for any receiving property by no more than:
a. Five dBA for 15 minutes in any one-hour period; or
b. Ten dBA for five minutes in any one-hour period; or
c. Fifteen dBA for 1.5 minutes in any one-hour period. [Ord. 818 § 1 (Exh. A), 2018]
No person shall operate any motor vehicle or any combination of such vehicle upon the public highways in violation of the standards specified in WAC 173-62-030, as amended from time to time, which is hereby adopted by reference. [Ord. 818 § 1 (Exh. A), 2018]
