The off-street parking and loading facilities required by this section shall be established prior to any change in the use of land or structures and/or prior to the occupancy of any new or enlarged structure.

Required off-street parking spaces shall provide vehicle parking only for residents, customers, patrons, and employees and shall not be used for the storage of vehicles or materials, the parking of vehicles used in conducting the business, or for the sale, repair or servicing of any vehicle.

Any area designated for required off-street parking shall not be used for any other purpose unless and until equal facilities are provided elsewhere and a site plan has been approved to reflect the change, or the primary use of the property is changed to a use requiring less off-street parking.

The required front yard in the R-3 district shall not be used for off-street parking for five or more cars unless the three-foot strip nearest the front property line is landscaped and a two-foot-high concrete, masonry, or decorative block wall, or wood fence, or a solid landscaping screen is provided. (For corner lots, see Section 17.05.040, Vision clearance at intersections.)

Table of Required Off-Street Parking. The parking standards in Table 6-1, Table of Off-Street Parking Standards, are hereby established as the parking standards for the uses indicated. These parking requirements are based on gross floor area. Gross floor area means the total square footage of all floors in a structure as measured from the interior surface of each exterior wall of the structure, and including halls, lobbies, enclosed porches and fully enclosed recreation areas and balconies, but excluding stairways, elevator shafts, attic space, mechanical rooms, restrooms, uncovered steps and fire escapes, private garages, carports, and off-street parking and loading spaces. Storage areas are included in gross floor area. However, the required off-street parking for storage areas shall be calculated at the rate of one space per five hundred square feet rather than the specific parking standard established in Table 6-1, except when the parking standard for the principal use would require fewer spaces (i.e., one space per six hundred square feet). All required off-street parking shall be subject to the procedures of this title and the standards of this section.

Uses Not Specified. Off-street parking requirements for uses not specifically listed in Table 6-1 shall be determined by the reviewing official based upon the requirement for similar uses.

Downtown Business District Exempt. The downtown business district of Wapato, as shown in Figure 6-1 and hereby adopted as a part of this chapter, shall be exempt from the provisions of this chapter as they relate to the number of parking spaces required; provided, that all the other requirements of this chapter shall apply to any parking provided by the applicant.

Fraction. If the number of off-street parking spaces required in Table 6-1 contains a fraction, such number shall be changed to the next higher whole number.

Mixed Uses. When different uses occupy a single structure or lot, the total required parking spaces shall be the sum of the requirements of the individual uses.

Shared Uses. Owners of two or more uses, structures, or parcels of land within three hundred feet of each other may share the same parking or loading area when the hours of operation do not overlap. The owners of two or more uses, structures, or parcels within three hundred feet of each other may also share facilities concurrently; however, the total parking requirements shall be the sum of the requirements for each individual use. Whenever shared parking is allowed under this section, the parking lot shall be signed so as to reasonably notify the public of the availability of use, and spaces shall not be assigned, allocated or reserved between uses.

A parking agreement approved by the administrative official shall be filed with the county auditor whenever two or more uses propose to share off-street parking facilities.

Tandem Parking. Parking spaces in tandem, having a single means of ingress and egress shall not be counted as two off-street parking spaces for the purpose of fulfilling the requirements of this chapter; except that each tandem space for single-family dwellings shall be counted as a required parking space.

For single- and two-family dwellings, parking facilities shall be located on the same lot or building site as the buildings they are required to serve.

For hospitals, convalescent, nursing or rest homes, parking facilities shall be located not more than one hundred fifty feet from the buildings they are required to serve.

For uses other than those specified above, parking facilities shall not be located over three hundred feet from the buildings they are required to serve.

Groups of five or more parking spaces shall be served by a driveway so that no vehicular backing or maneuvering movement will occur within a public right-of-way other than an alley.

No parking lot or driveway serving a nonresidential use in a commercial or industrial district shall be located in a residential zoning district.

The standard for landscaping of parking lots with five or more spaces shall be five percent of the total parking area.

The planted area standard shall be twenty-four square feet in area with the exception of raised planter boxes around buildings.

A standard of one tree from an approved list shall be planted for every fifteen single-row parking stalls or every thirty double-row parking stalls within the parking lot.

Landscaping shall consist of combinations of trees, shrubs, and ground cover with careful consideration to eventual size and spread, susceptibility to disease and pests, durability, and adaptability to existing soil and climatic conditions.

Every parking area that abuts property in any residential district shall be separated from such property by a solid wall, view-obscuring fence, or compact evergreen hedge at least six feet in height. The screening shall be provided and maintained along the property line of such lot except in the required front yard.

Surfacing. Paved with two-inch-thick asphaltic surfacing on an aggregate base, or an equivalent surfacing acceptable to the reviewing official, so as to eliminate dust or mud.

Grading and Drainage. Graded and drained so all surface water is disposed of on site. Grading and drainage facilities shall be designed according to accepted engineering standards.

Border Barricades. Any parking or motor vehicle sales areas abutting the street property line shall provide a concrete curb or timber barrier at least six inches in height and located at least two feet from the street property line. The curb or barrier shall be securely anchored. No curb or barrier shall be required across any driveway or entrance to the parking area, or if the parking lot is separated from the street by a fence or a hedge.

Markings. All parking spaces (except motor vehicle sales areas) shall be marked by durable painted lines at least four inches wide and extending the length of the stall or by curbs or other means approved by the reviewing official to indicate individual parking stalls. Signs or markers located on the parking lot surface shall be used as necessary to ensure safe and efficient use of the parking lot.

Loading Space Size. The required loading space shall be of adequate size to accommodate the maximum number and size of vehicles simultaneously loading or unloading at the structure. Each off-street loading space shall have the minimum dimensions of twelve feet in width and twenty-five feet in length. On-site maneuvering space not less than twenty-five feet in length shall be provided adjacent to the loading dock. This maneuvering space shall not include any area designated for off-street parking.

Loading Space Location. Required off-street loading and related maneuvering space shall be located on or abutting the property served. No part of any vehicle using the loading space shall project into the right-of-way of any public or private road.
