The following manufacturing districts are established; properties so designated shall be subject to the provisions contained in this chapter:

Designation and Purpose. The manufacturing districts are intended to provide appropriately located areas for various manufacturing enterprises, industrial establishments, research developments and compatible commercial services that enhance the city's economic base and provide jobs for residents of the area, while at the same time ensuring a high quality of life free from excessive noise, odors, dust, smoke, heavy traffic congestion and air and water pollution. In addition to this intent, each manufacturing district has its own specific and unique intent as follows:

The following table details permitted and conditionally permitted uses in the manufacturing districts. Where a "P" is indicated, the respective use in the same row is permitted in the zone classifications in the same column. Where an "A" is indicated or SMC § 18.48.020(B) applies, the respective use in the same row is allowed through an administrative use permit. An administrative use permit shall be required and in full force and effect in order to establish said administrative uses. Where a "CUP" is indicated, the respective use in the same row is conditionally permitted in the zone classification in the same column. A conditional use permit shall be required and in full force and effect in order to establish said conditional uses. Where "--" is indicated, the respective use is not allowed. Where a "1" or "2" is indicated, there are different or supplemental regulations for that particular use within the Sumner manufacturing/industrial core overlay (MICO) pursuant to the notes at the bottom of this table.

Use Interpretations. Whenever a property improvement permit is applied for, for property in the manufacturing districts, the director shall determine under which of the use classifications set forth above the proposed use shall be classified. All such determinations shall be based upon a finding that the use is consistent with the description and purpose for the respective manufacturing districts set forth and that such uses are similar to and no more detrimental than the types of use examples provided in the definition of the relevant use classification set forth. All determinations pursuant to this section may be appealed as a request for interpretation to the hearing examiner.

The use shall not be visible from freeways, principal arterials, or minor arterials as identified in the Sumner comprehensive transportation plan. Visibility shall be reduced by meeting the provisions of SMC § 18.18.060 (C)(2)(a), (b), (d), (e), (g) and (h).

A landscape and fencing plan shall be submitted for review and approval by the development services director.

Exterior Mechanical Devices. In the M-1 zones, air conditioners, heating, cooling, ventilating equipment, pumps and heaters and all other mechanical devices shall be screened from surrounding properties and streets and shall be so operated that they do not disturb the peace, quiet and comfort of neighboring residents. Apparatus needed for the operation of active or passive solar energy systems need not be screened pursuant to this subsection.

Required Landscaping. All required yards adjacent to the street shall be landscaped, except for driveways and sidewalks, as per the requirements in the Sumner design and development guidelines. Wherever landscaping is required by this title and/or by conditions of approval of discretionary applications required by this title, such landscaping shall be permanently maintained in a neat and orderly manner. In no event shall such landscape areas be used for the storage of materials or parking of automobiles. For new developments a landscape plan shall be prepared and submitted for review by the development services director as per the requirements in chapter 18.41 SMC.

Maximum Height Limitations. Maximum height limitations may be adjusted through approval of a special exception by the hearing examiner. In addition to the criteria of SMC § 18.50.040, the hearing examiner shall consider whether the request will have potential impacts to emergency services and public views.

Manufacturing District Properties Adjacent to Residential Properties. Whenever M-1 or M-2 zoned property abuts any residential zone, a six-foot masonry wall or wood fence shall be established and maintained along the side or rear property line that abuts the residential zones subject to the sight distance requirements of SMC § 18.32.040.

Trash Receptacles. Trash receptacles and recycling bins enclosed within gated, solid walls or fences shall be provided for each industrial use and/or industrially used property. The receptacles shall be set back a minimum of 15 feet from any residentially zoned property boundary and shall be maintained in a neat and sanitary condition.

Electrical Disturbance, Heat and Cold, Glare. No use except a temporary construction operation shall be permitted which creates changes in temperature or direct glare, detectable by the human senses without the aid of instruments, beyond the boundaries of the site. No use shall be permitted which creates electrical disturbances that affect the operation of any equipment.

Odor and Emissions. No use shall be permitted which creates annoying odor in such quantities as to be readily detectable beyond the boundaries of the site or produces air emissions that are not compliant with regional, state, and federal emission standards. Uses shall utilize best available control technologies to reduce odors and emissions.

Radioactivity. The use of radioactive materials shall be limited to measuring, gauging and calibration devices.

Vibration. No use except a temporary construction operation shall be permitted which generates inherent and recurrent ground vibration perceptible, without instruments, at the boundary of the lot in which the use is located.
