18.18.010 Purpose.

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

1. M-1, light manufacturing district.

2. M-2, heavy manufacturing district.

3. Manufacturing/industrial core overlay (MICO).

B. 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:

1. M-1, light manufacturing district: The M-1 district is intended to provide areas for light manufacturing, general industrial activities, warehousing and limited service commercial uses that are complementary and are not detrimental to either existing or proposed industrial uses, or neighboring commercial and residential districts. Typical uses in this district include assembling and manufacturing of products from previously prepared material, and may include planned industrial parks which are designed to ensure compatibility between the industrial operations therein and the existing activities and character of the community in which the park is located.

2. M-2, heavy manufacturing district: The M-2 district is intended to provide areas for heavy manufacturing uses involving activities that do not complement the character of commercial or residential areas. M-2 zoned areas should be located so as to ensure that heavy manufacturing uses will not result in detrimental impacts to commercial or residential zones. Typical uses in this district include processing of natural and manmade materials for use in general manufacturing.

3. Manufacturing/industrial core overlay (MICO): The MICO is an overlay zone applied within the M-1 and M-2 districts, where limited alternate or additional regulations apply as noted in this chapter. The intent of the MICO is to apply additional restrictions on uses that may be incompatible with current manufacturing and industrial uses and the intensification of these uses in the future consistent with the city of Sumner comprehensive plan. (Ord. 2319 § 5, 2010: Ord. 1739 § 24, 1996: Ord. 1694 § 1, 1995)
