19.27.020 Additional development standards in the M-1 zone.
In addition to the development standards contained in Table 6.1 of this title, the following development standards apply to uses hereafter established in the M-1 zone.
A. Building Design.
1. Prefabricated metal buildings and buildings with corrugated metal siding shall be prohibited. Exterior building finish for buildings located within three hundred feet of residentially zoned properties shall be approved by the planning director, using the review process as described in Title 15, Local Project Review Procedures.
2. Buildings with exterior walls greater than sixty feet in length shall be required to provide architectural modulation, in accordance with the following standards:
a. Minimum modulation depth equals five feet;
b. Minimum modulation length equals fifteen feet;
c. Maximum modulation length equals sixty feet;
d. Minimum height of modulation equals fifty percent of height of facade;
e. Any other method of architectural modulation which results in an equivalent or superior articulation of the building facade, which gives the building the appearance of not having flat facade surfaces for substantial portions of its length, based upon building plan elevations to be approved using the review process as described in Title 15, Local Project Review Procedures. Examples of acceptable architectural treatment include, but are not limited to, building facade modulation, orientation of doors and windows, varying use of building materials and colors, use of landscaping which breaks up flat expanses of building walls, or a combination of techniques providing the desired effect.
3. Exterior building materials shall be selected so as not to project or reflect natural or artificial lighting or glare into residential areas.
4. Mechanical equipment located on the roof, facade, or external portion of a building shall be architecturally screened by incorporating the equipment in the building and/or site design so as not to be visible from adjacent properties or public streets.
5. Equipment or vents which generate noise or air emissions shall be located away from adjoining residentially zoned properties.
B. Landscaping. In addition to the perimeter landscaping required by Chapter 19.35, site landscaping shall be provided in accordance with the standards of this section. Where this section specifies a requirement which is different from the standards of Chapter 19.35, the more substantial requirements shall apply.
1. Each building shall be surrounded by fifteen feet of landscaping, except for loading areas, access to buildings and pedestrian walkways up to five feet in width. Landscaping within this area shall consist of:
a. A mix of evergreen and deciduous trees and shrubs, with lawn or hardy ground cover which will cover seventy-five percent of the landscape area within two years of planting.
b. Trees shall be planted at a density of three per one thousand square feet of landscape area. Evergreen trees shall be minimum of six feet tall at the time of planting and deciduous trees a minimum diameter of one and one-half inches, measured at six inches above the ground.
2. Outdoor parking areas shall be separated from streets and abutting properties in accordance with the standards of Chapters 19.34 and 19.35.
C. Loading. Truck loading, parking and maneuvering areas shall be screened from abutting properties and streets by a sight-obscuring fence eight feet in height, enclosed within a ten-foot-wide landscaped area planted to Type II standards.
D. Outdoor Storage. Outdoor storage areas shall be permitted to occupy an area not more than five percent of the area of the building footprint of the principal building. Outdoor storage shall not be permitted within required building setback areas. Outdoor storage areas shall be enclosed by a sight-obscuring fence eight feet in height surrounded by ten-foot wide landscaped area planted to Type II standards.
E. Minimum Lot Size. A lot area of less than five acres shall be permitted under the following circumstances:
1. Minimum lot area shall be not less than two acres.
2. Not more than four contiguous lots containing less than five acres shall be permitted.
3. Except as permitted in subsection E.2 of this section, each lot or group of up to four lots containing less than five acres each shall be located a minimum of one thousand feet from any other lots containing less than five acres located in the M-1 zone.
4. Variances to the development standards of the M-1 zone shall not be permitted on lots containing less than five acres.
5. Land divisions or land development approvals which were authorized by the city prior to the effective date of the ordinance codified in this title which approved a minimum lot size of less than five acres shall remain valid.
F. Open Space. There shall be provided on each lot a minimum open space area or areas, containing at least twenty percent of the lot area, developed in accordance with the following standards:
1. All of the required open space shall be landscaped, as required by this chapter, provided in natural open areas, or improved with passive or active recreational facilities.
2. The required building setback areas, and the building landscaping required by subsection B.1 of this section may be included in the calculation of required open space.
3. Driveways, loading areas, outdoor storage, parking lots and the interior landscaping required in parking lots shall not be considered as satisfying the open space requirements.
4. No variance shall be granted to allow the minimum open space area or areas to be less than twenty percent of the lot area.
G. Prohibited Manufacturing Uses. The following manufacturing uses are prohibited in the M-1 zone except as otherwise permitted in Section 19.27.040:
1. Manufacturing involving outdoor storage which exceeds the maximum land area permitted by subsection D of this section;
2. Manufacture or storage of explosives;
3. Stockyards, dairies, slaughterhouses, rendering plants, canneries, and other agricultural industries;
4. Petroleum refineries;
5. Bulk fuel storage, unless stored in tanks and accessory to a permitted use located on the same lot;
6. Truck parking, repair and maintenance unless accessory to a permitted use located on the same lot;
7. Cement manufacturing;
8. Blast furnaces;
9. Smelting;
10. Drop forge industries;
11. Fertilizer manufacture;
12. Sanitary landfills;
13. Waste to energy facilities;
14. Solid waste transfer stations;
15. Sewage treatment plants;
16. Lumber, pulp or paper mills;
17. Cargo container storage;
18. Asphalt or concrete batch plant;
19. Other similar heavy manufacturing uses with potentially noxious impacts, as determined by the planning director, except as otherwise provided by this chapter. In making such a determination, the city shall use the procedures as described in Title 15, Local Project Review Procedures. (Ord. 3618-18 § 14, 2018; Ord. 2538-01 §§ 12, 13, 2001; Ord. 2397-99 § 43, 1999: Ord. 1849-92 §§ 13, 14, 1992; Ord. 1671-89 (part), 1989.)
19.27.030 Land developments authorized by the city prior to the effective date of the ordinance codified in this title.

B. The minimum standards of the M-1 zone;
C. An authorization granted through the variance procedure described in Chapter 19.41 of this title;
D. Development approved using the PD planned development overlay zone. (Ord. 2397-99 § 44, 1999: Ord. 1671-89 (part), 1989.)
19.27.040 Map number 27-1—Aggregates extraction, related manufacturing activity.
The following regulations shall apply to the area identified by map number 27-1:
A. Manufacturing activities which comply with the standards of the M-1 zone shall be permitted.
B. Related manufacturing includes asphalt or concrete batch plants, cement products manufacturing, and other similar activities related to aggregates mining occurring on site.
C. Related manufacturing activities existing as of January 13, 1990, may continue in the same capacity. Any change in the type of manufacturing activities on such sites which do not comply with the M-1 zone permitted uses and standards shall be subject to the review process as described in Title 15, Local Project Review Pro-cedures, and shall be limited to the area indicated by map number 27-1. The review authority shall establish additional standards and may impose conditions which are necessary to make such manufacturing areas compatible with surrounding properties.
D. Areas reclaimed from aggregates mining shall be limited to other permitted M-1 uses and subject to the standards of the M-1 zone.
