This section includes special regulations for certain land use categories and activities. These regulations are in addition to other development standards in other parts of these regulations, such as chapter 17.40 (site planning and development standards). The intent of this section is to ensure that the uses regulated are compatible with the surrounding uses.

(Ord. No. 813, att.(45.5), 6-25-2024; Ord. No. 823, att.(47.70), 7-22-2025)

(a)

Purpose. The purpose of this section is to establish site planning, development, and/or operating standards for various specific and unique land uses and activities. It is the city's intent, in establishing these standards, to mitigate the potential adverse impacts of these uses and activities on adjacent and surrounding land uses by applying special design requirements, regulating activities within the use, and establishing special setback and other development standards.

(b)

Applicability. Unless otherwise specified, regulations within this section apply to all specified uses in all zoned areas of the city. The regulations and standards contained in this section shall apply to various specific and unique land uses and activities and shall be in addition to any other development standards and regulations contained elsewhere within these regulations (e.g., lighting, landscaping, parking). These uses may only be located in those zoning districts as described in the use district charts and shall only be authorized in concert with the permit requirements of chapters 17.15 through 17.20 (use district charts).

(Ord. No. 813, att.(45.10), 6-25-2024; Ord. No. 823, att.(45.10), 7-22-2025)

(a)

Purpose and applicability. The regulations contained in this section shall apply to caretaker housing, as defined in chapter 17.5 (definitions). The establishment of caretaker housing shall be consistent with the allowed use regulations and bulk and dimensional requirements of chapters 17.15 through 17.20 (use district charts) and the standards contained in this section, as well as with other development standards as required in the underlying zoning district. Where the standards of the underlying district conflict with the standards herein, the more restrictive shall apply. Caretaker housing is only allowed in commercial and industrial districts (O-B, C-1, C-3,I-1, and I-2).

(b)

Design. One caretaker housing unit, providing housing to no more than one family, may be permitted in conjunction with an otherwise permitted nonresidential use on the same property. The residential use must be associated with and directly support the nonresidential use of the property (e.g., night watchman or site superintendent for an industrial use or housing for employees who are compensated for conducting on-site work). Immediate family members may also reside within the on-site housing. The residential use may not exceed 100 percent of the business building or 5,000 square feet, whichever is smaller.

(1)

Design standards.

a.

Single-family, manufactured, modular, or stick-built homes shall be allowed as residential caretaker housing. Any manufactured home shall comply with standards for individual manufactured homes (see section 17.45.25).

b.

Separation and access. If the caretaker housing unit is detached from the working space, it shall be separated from other buildings and other uses on the property by at least 100 feet.

c.

Integration of living and working space. If the living space of a caretaker housing unit is designed as an integral part of the working space, it shall be designed to accommodate commercial or industrial uses, as evidenced by the provision of ventilation, interior storage, flooring, and other physical improvements of the type commonly found in exclusively commercial or industrial facilities used for the same work activity.

(Ord. No. 813, att.(45.15), 6-25-2024; Ord. No. 823, att.(45.15), 7-22-2025)

(a)

Purpose and applicability. The purpose of this section is to allow limited business activity to occur at a residence where the business activity is clearly incidental to the primary residential use and will not change the residential character of the neighborhood.

(b)

Definition. A home occupation is an accessory, nonresidential business activity that is conducted within a dwelling by its inhabitants, incidental to the residential use of the dwelling, which does not change the character of the surrounding area by generating more traffic, noise, or storage of material than would be normally associated with a residential zone. Childcare facilities are excluded from this section and are regulated under section 17.45.50 (special regulated uses).

(c)

Approval. Home occupations are allowed as part of any residential use, provided the requirements of this section are met by approval of the applicable director using a Review Process 2.

(d)

Performance standards. It is the intent of the following standards to reduce the impact of the home occupation to the degree that its effects on the neighborhood are undetectable from normal and usual residential activity. These standards shall be incorporated as conditions of approval for the home occupation.

(1)

Number of home occupations. One home occupation is allowed in a dwelling.

(2)

Employees. A home occupation shall have no more than one off-site employee. Other off-site employees may be employed by the business, but they may not report to the home office. No more than two full-time residents may be employed at the home occupation.

(4)

Off-site effects. There shall be no mechanical equipment used or operations which create or make dust, odor, vibration, noise, or other effects detectable at the property line of the property in which the home occupation is located.

(5)

On-site sales. There shall be no products sold on the premises except artists' originals or products individually made to order on the premises, or as part of electronic commerce. Products that are not artists' originals or individually made to order may be constructed on site, using equipment normally found in a residence; however, these products may only be sold at a permitted commercial location.

(6)

Display. There shall be no display of products produced by occupants of the dwelling that are visible in any manner from the outside of the dwelling unit.

(7)

Traffic/vehicles. The use shall not generate vehicular traffic beyond that which is normal in a residential district nor, in any case, require the parking of more than one additional vehicle per hour.

(8)

Storage. There shall be no storage of material, products, or supplies outdoors.

(9)

Exterior appearance. There shall be no remodeling or construction of facilities for the home occupation that changes the external appearance of the residence from a residential to a more commercial-appearing structure when viewed from the front of the building. Conversion of a portion of the interior of the structure (e.g., a garage) that does not result in a loss of off-street parking or alters the exterior appearance of the structure may be allowed through issuance of a building permit.

(10)

Signs. Home occupations may display a nameplate not more than two square feet in area, flush-mounted to the residence. No other signage or display that will indicate from the exterior that the building is being utilized in part for any purpose other than that of a dwelling is permitted.

(11)

Visitors and customers. Visitors and customers shall not exceed those normally and reasonably occurring for a residence, including not more than two business visitors per hour and no more than two at any given time.

(12)

Infrastructure. The home occupation shall not create a need for off-street parking, pedestrian and vehicular traffic, sanitary sewer and storm sewer usage, public water usage, as well as other municipal services in excess of the normal and usual levels for other residential dwellings.

(13)

Hazardous materials. Storage of hazardous materials may only be stored in amounts below the thresholds as established by the local fire department.

f.

Technical information explaining the reasons that a permit is being sought (e.g., for wireless communication towers, whether a new antenna is necessary to accommodate increased demand or to fill a "dead zone" in the provider's coverage area), the reasons that the subject site is considered necessary to accomplish the provider's coverage objectives, and the reasons that the proposed site is the most appropriate location under existing circumstances.

(5)

General development standards. Unless otherwise exempt, the following general development standards shall apply to all telecommunication facilities:

a.

All telecommunication facilities shall comply with all applicable requirements of the current building code and these regulations, as well as other standards and guidelines adopted by the city.

b.

To minimize the overall visual impact, new telecommunication facilities shall be encouraged to collocate with existing facilities, with other planned new facilities, and with other facilities such as water tanks, light structures, and other utility structures whenever feasible and aesthetically desirable. To facilitate collocation when deemed appropriate, conditions of approval for conditional use permits shall require all service providers to cooperate in the siting of equipment and antennas to accommodate the maximum number of operators at a given site when found to be feasible and aesthetically desirable. The applicant shall agree to allow future collocation of additional antennas and shall not enter into an exclusive lease for the use of the site.

c.

At least ten feet of horizontal clearance shall be maintained between any part of the antenna and any power lines unless the antenna is installed to be an integral part of a utility tower or facility.

d.

Site design. All facilities (including related equipment) shall be designed to minimize the visual impact to the greatest extent possible, considering technological requirements, by means of placement, screening, and/or camouflage, to be compatible with existing architectural elements, landscape elements, and other site characteristics. The applicant shall use the smallest and least visible antennas possible to accomplish the owner/operator's coverage objective. A visual impact analysis is required to demonstrate how the proposed facility will appear from public rights-of-way.

e.

Safety design. All facilities shall be designed so as to be resistant to and minimize opportunities for unauthorized access, climbing, vandalism, graffiti, and other conditions that would result in hazardous conditions or visual blight.

f.

Location. Towers shall not be located in any required front or streetside yard in any zoning district. The setback distance from any abutting street right-of-way or residential property line shall be equal to the height of the facility (tower and related equipment). Otherwise, the minimum setback distance from all other property lines shall be at least equal to 100 percent of the height of the tower.

g.

Height limit. The height limit for towers shall be consistent with the maximum building height of the zoning district of the subject parcel and any applicable federal aviation administration regulations. Exceptions to the height limit may be granted when the applicable director finds that reasonable alternatives do not exist to provide the necessary service. There is no height limit specified for collocations on existing structures, provided facilities are screened from the view of abutting street rights-of-way or camouflaged by matching the color(s) and/or material(s) of the structure to which it is attached.

h.

Lighting. The applicable director shall require approved lighting for towers and related equipment.

i.

Landscape. The applicable director shall approve landscaping.

j.

Design/finish. New towers shall have subdued colors and nonreflective materials that blend with the colors and materials of surrounding areas.

k.

Advertising. The tower and related equipment shall not bear any signs or advertising devices other than certification, warning, or other required seals or signs.

(6)

Development standards for antennas (excluding amateur radio antennas). Unless otherwise exempt pursuant to subsection (3) (exemptions), the following development standards shall apply to receive-only antennas (ground- and building-mounted), parabolic antennas, and satellite earth stations as defined in this section.

a.

Antenna location. Parabolic antenna and satellite earth stations shall be ground-mounted in residential zoning districts. In all nonresidential zoning districts, the preference is for a building-mounted antenna. No antenna shall be located in the required front or street side yard of any parcel unless entirely screened from pedestrian view of the abutting street rights-of-way (excluding alleys). In all zoning districts, ground-mounted antennas shall be situated as close to the ground as possible to reduce visual impact without compromising their function, and all portions of the structure/antenna shall be set back a minimum of five feet from any property line.

b.

Height limit. The height limit for a ground-mounted antenna is six feet. However, the height may be increased to a maximum of 15 feet if the setback distance from all property lines is at least equal to the height of the antenna and if the structure is screened in accordance with subsection c. (screening) below. Building- and roof-mounted antenna shall not extend above the roofline, parapet wall, or other roof screen beyond a maximum of four feet or extend out from the face of the building or other support structure by more than 18 inches.

c.

Screening. Ground-mounted antennas shall provide screening to meet the approval of the applicable director. In order to facilitate collocations, screening will be reduced to 50 percent for the placement of antennas on existing towers when there is no increase in the overall height of the tower.

(7)

Operation and maintenance standards.

a.

Non-ionizing electromagnetic radiation (NIER) exposure. No telecommunication facility shall be sited or operated in such a manner that it poses, either by itself or in combination with other such facilities, a potential threat to public health. To this end, no facility or combination of facilities shall produce, at any time, power densities in any inhabited area that exceed the FCC's maximum permissible exposure (MPE) limits for electric and magnetic field strength and power density for transmitters or any more restrictive standard subsequently adopted or promulgated by the city, or by the county, state, or federal government.

(8)

Removal regulations. In the event one or more telecommunication facilities are not operated for the provision of telecommunication services for a continuous period of three months or more, such facilities shall be deemed abandoned. The facilities shall be removed within 30 days following the mailing of written notice that removal is required. If two or more providers of telecommunication services use the antenna support structure or related equipment, the period of nonuse under this section shall be measured from the cessation of operation at the location by all such providers. Failure to remove within the time required under these regulations shall constitute a violation.

(9)

Effects of development. The city shall not be liable if development within the city, after installation of a telecommunication facility, impairs reception.
