17.30.040 Parking, loading, service areas and screening service areas, and screening.
A. General Standards.
1. Unless otherwise specified all parking standards and other requirements contained in Chapter 17.44 shall apply.
2. Required parking may be located within a required front or side yard setback if consistent with other standards and guidelines of the Airport Guidelines.
3. Required parking for aviation-related uses shall be calculated as follows:
a. One space for each four private aircraft occupying a hanger space or tie-down space.
b. One space per three hundred fifty square feet of office-type space.
c. One space per one thousand square feet of space devoted to aircraft maintenance activities.
d. One space per five hundred square feet of space used for manufacturing, assemblage, or research activities.
4. Required parking may be located either on the building site or off site; provided, that: (a) off-site parking spaces are within seven hundred feet of the site; and (b) use of the off-site spaces is reserved for exclusive use of the site tenants and their visitors, clients, and customers; and (c) the site tenant has entered into a legally binding contract assuring availability of the required space as long as the permitted use is in operation.
5. Loading areas for new buildings shall face the side or rear property line and shall be designed to be an integral part of the building architecture. The rear property line for apron sites shall be the line adjoining the aircraft operating side.
6. Where side loading occurs for new buildings it shall be screened from the street by a wall with a minimum height of eight feet and a maximum height of ten feet for freestanding walls.
7. For buildings within the A-2 district which were in existence on January 1, 2003, loading areas within three hundred feet of the right-of-way of either Imjin or Neeson Roads shall be screened if and as determined necessary by the site and architectural design review board or the appropriate appellate body under Section 17.56.060. Other loading areas for buildings which were in existence on January 1, 2003, are not required to be screened.
8. Minimum dimensions for truck loading areas serving buildings with industrial or research functions shall be twelve feet wide, forty-five feet long, and have fourteen-and-one-half-foot vertical clearance.
9. Loading and service areas shall be designed so that the loading and serving operation occurs within the confines of the building site.
10. All service areas with exterior storage of materials or equipment shall be located at the rear of the building and be totally screened from view by a wall with a minimum height of eight feet or a combination of fencing and dense vegetation of equivalent height forming a visual barrier comparable to a solid wall. The maximum height of a freestanding wall shall be ten feet.
B. Landscape Screening. The recommended method of screening of outdoor storage areas, refuse collection facilities, and loading areas is by means of building siting and use of walls architecturally integrated into the overall building architecture. If landscape materials are used for purposes of screening such facilities, landscaping should adhere to the following standards:
1. Areas Requiring Screening. Screening of storage and utility areas is required as follows:
a. Open storage areas, including refuse collection and storage, recycling storage, and loading areas generally involving less activity than service areas, each visible from adjacent properties and not separated by a public right-of-way, shall be enclosed by a screen at least six feet but not more than ten feet in height. Items stored within one hundred feet of a street or adjoining parcel shall not be stacked higher than the required screen. All dumpsters shall be closed with tight-fitting lids to minimize bird attractant hazards.
b. Exterior electrical cage enclosures, cooling, heating, ventilating, other mechanical equipment, and storage tanks shall be screened from view and directed away from adjacent public rights-of-way.
2. Materials. Screens shall include the installation and maintenance of at least one or a combination of the following materials:
a. Dense vegetation;
b. Solid fencing combined with dense vegetation; or
c. Walls.
3. Opacity. When plants are used for screening they shall be:
a. Of a variety that will provide a year-round barrier at the required height;
b. Planted at a spacing and plant size to achieve a minimum seventy-five percent opacity within two years and one hundred percent within five years;
c. Supplemented or replaced with other dense landscaping or a fence or wall if the landscape screen fails to achieve or retain the required opacity. (Ord. 2020-07 § 2, 2020; Ord. 2003-06 § 1, 2003; Ord. 2000-10 § 1, 2000)
