MAXIMUM_PERMISSIBLE_SOUND_LEVELS_AT_RECEIVING_LAND_USE; 1. The noise standards for the various categories of land use identified by the Noise Control Office(r) as presented in Table 070.1 shall, unless otherwise specifically indicated, apply to ali such property within a designated zone. 2. No person shall cause or allow to cause, any source of sound at any location within the incorporated City or allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person, which causes the noise level when measured on any other property, either incorporated or, unincorporated, to exceed; (a) the noise standard for that land use as specified in Table 070.1 for a cumulative period of more than thirty minutes in any hour; or zones, the noise (b) the noise standard plus 5 dB for a cumulative period of more than fifteen minutes in any hour; or (c) the noise standard plus 10 dB for a cumulative period of more than five minutes in any hour; or (d) the noise standard plus 15 dB for a cumulative period of more than one minute in any hour; or (e) the noise standard plus 20 dB for any period of time. , 3 If the measured ambient level differs from that permissible perm ss e within any of the first four noise limit categories above, the allowable noise exposure standard shall be adjusted in 5 dB increments in each category as appropriate to encompass or, reflect said ambient noise level. In the event the ambient noise level exceeds the fifth noise limit category, the maximum allowable noise level under this category shall be increased to reflect the maximum ambient noise level. 4. If the measurement location is on a boundary between two different zones, the noise level limit applicable to the lower noise zone plus 5 dB, shall apply. 16 5. If possible, the ambient noise should be measured at the same location along the property line utilized in 060, with the alleged offending noise source inoperative. If for any reason the alleged offending noise source cannot be shut down, the ambient noise may be estimated by performing a measurement in the same general area of the source but at a sufficient distance such that the noise from the source is at least 10 dB below the ambient in order that only the ambient level be measured. If the difference between the ambient plus the noise source and noise source is 5 to 10 dB, then the level of the source itself can be reasonably determined by subtracting a one decibel correction to account for the contribution of the source. B. CORRECTION_FOR_CHARACTER_OF_SOUND; In the event the alleged offensive noise, as determined by the Noise Control Officer, contains a steady, audible tone such as whine, screech, or hum, or, is a repetitive noise such as hammering or riveting, or contains music or speech, the standard limits set forth in Table 070.1 shall be reduced by 5 dB. 17 TABLE 060.1 EXTERIOR NOISE LIMITS (Levels Not To Be Exceeded More Than 30 Minutes In Any Hour) Noise Level (dBA) ' Zon|ng Time Category Period R1 & R2, C/OS Low Density 10 pm - 7 am 50 Residential 7 am - 10 pm 55 R3&R4 High Density 10 pm - 7 am 50 Residential 7 am - 10 pm 55 O, PF 10 pm - 7 am 55 Ltd.

Additional area classifications should be used as appropriate to reflect both lower and higher existing ambient levels than those shown. Industrial noise limits are intended primarily for use at the boundary of industrial zones rather than for noise reduction within the zone. / 18 MR 9.12.070 INTERIOR NOISE STANDARDS MAXIMUM_PERMISSIBLE_DWELLING_INTERIOR_SOUND_LEVELS; 1. The interior noise standards for multi-family residential dwellings as presented in Table 070.1 shall apply, unless otherwise specifically indicated, within all such dwellings with windows in their normal seasonal configuration.

No person shall operate or cause to be operated within a dwelling unit, any source of sound or allow the creation of any noise which causes the noise level when measured inside a neighboring receiving dwelling unit to exceed; (a) the noise standard as specified in Table 070,1 for a cumulative period of more than five minutes in any hour; or, (b) the noise standard plus 5 dB for a cumulative period of more than one minute in any hour; or (c) the noise standard plus 10 dB or the maximum measured ambient, for any period of time. 3. If the measured ambient level differs from that permissible within any of the noise limit categories above, the allowable noise exposure standard shall be adjusted in 5 dB increments in each category as appropriate to reflect said ambient noise level. 19 B. CORRECTION_FOR_CHARACTER_OF_SOUND; In the event the alleged offensive noise, as determined by the Noise Control Officer, contains a steady, audible tonesuch as a whine, screech, or hum, or is a repetitive noise such as hammering or riveting, or contains music or speech conveying informational content, the standard limits set forth in Table 070.1 shall be reduced by 5 dB. 20 SECTION 9.12.080 MOTOR VEHICLE NOISE LIMITS A. REFUSE_COLLECTION_VEHICLES; B. 1. No person shall collect refuse with a refuse collection vehicle between the hours of 7 p.m. and 6;30 a.m. within or adjacent to a residential area.

If, at the end of the 2 year period, it can be shown that compliance with the provisions herein constitutes a hardship in terms of technical and economic feasibility, a exception may be granted on an annual basis until such time as compliance may be effected. No more than 3 exceptions will be allowed on a specific project. 23 SECTION 9.12.100 A. SPECIAL_EXCEPTIONS; 1. The NCO is authorized to grant exceptions from any provision of this ordinance, subject to limitations as to area, noise levels, time limits, and other terms and conditions as the NCO determines are appropriate to protect the public health, safety, and welfare from the noise emanating therefrom. This section shall in no way affect the duty to obtain any permit or license required by law for such activities. 2. Any person seeking an exception pursuant to this section shall file an application with the NCO. The application shall contain information which demonstrates that bringing the source of sound or activity for which the exception is sought into compliance with this ordinance would constitute an unreasonable hardship on the applicant, on the community, or on other, persons. The application shall be accompanied by a fee as established by council resolution. A separate application shall be filed for each noise source; provided, however, that several mobile sources under common ownership, or several fixed sources on a single property may be combined into one application. Any individual who claims to be adversely affected by allowance of the exception may file a statement with the NCO containing any information to support his claim. If at any time the NCO finds that a sufficient controversy exists regarding an application, a public hearing will be held. 3. In determining whether to grant or deny the application, the NCO shall balance the hardship on the applicant, of not granting the exception against the adverse impact on the health, safety, and welfare of other persons affected, the adverse impact on property affected, and any other adverse impacts of granting the exception. Applicants for exceptions and persons contesting exceptions may be required to submit such information as the NCO may reasonably require. In granting or denying an application, the NCO shall keep on public file a copy of the decision and the reasons for denying or granting the exception. 24 4" Exceptions shall be granted by notice to the applicant containing all necessary conditions, including a time limit on the permitted activity. The exception shall not become effective until all conditions are agreed to by the applicant. Noncompliance with any condition of the exception shall terminate the exception and subject the person holding it to those provisions of this ordinance for which the exception was granted. 5.
