The purpose of this chapter is to provide basic and flexible standards for development of vehicle and bicycle parking. The design of parking areas is critically important to the viability of some commercial areas, pedestrian and driver safety, the efficient and safe operation of adjoining streets, and community image and livability. Historically, some communities have required more parking than is necessary for some land uses, paving extensive areas of land that could be put to better use. Because vehicle parking facilities can occupy large amounts of land, they must be planned and designed carefully to use the land efficiently while maintaining the visual character of the community. This chapter recognizes that each development has unique parking needs by providing a flexible approach for determining parking space requirements (i.e., "minimum" and "performance-based" standards). This chapter also provides standards for bicycle parking because many people use bicycles for recreation, commuting, and general transportation. Children as well as adults need safe and adequate spaces to park their bicycles throughout the community.
All developments in the City of Warrenton shall comply with the provisions of this chapter.
At the time a structure is erected or enlarged, or the use of a structure or parcel of land is changed within any zone in the City, off-street parking spaces shall be provided in accordance with requirements in this section, chapter, and Code, unless greater requirements are otherwise established. The minimum number of required off-street vehicle parking spaces (i.e., parking that is located in parking lots and garages and not in the street right-of-way) shall be determined based on the standards in Table 16.128.030.A.
A. 
General Provisions.
1. 
Groups of four or more off-street parking spaces shall be served by a driveway or aisle so that no backing movements or other maneuvering within a street or right-of-way, other than an alley, will be required. Section 16.120.020 contains driveway opening and width standards.
2. 
Service drives or aisles to off-street parking areas shall be designed and constructed to facilitate the flow of traffic and to provide maximum safety to pedestrian, bicycle, and vehicular traffic on the site.
3. 
Service drives or aisles shall be clearly and permanently marked and defined through the use of bumper rails, fences, buildings, walls, painting, or other appropriate markers.
4. 
Fractional space requirements shall be counted as a whole space.
5. 
All parking lots shall be designed and constructed to meet the City standards of Section 16.120.020, this chapter, Chapter 16.136, and this Code.
6. 
Uses not specifically listed above shall furnish parking as required by the Community Development Director, who shall consider uses similar to those listed in Table 16.128.030.A and the Institute of Traffic Engineers Parking Generation as guides for determining requirements for other uses.
7. 
Parking spaces and parking areas may be used for transit related uses such as transit stops and park- and-ride/rideshare areas, provided minimum parking space requirements can still be met.
8. 
Parking areas that have designated employee parking and more than 20 automobile parking spaces shall provide at least 10% of the employee parking spaces (minimum two spaces) as preferential carpool and vanpool parking spaces. Preferential carpool and vanpool parking spaces shall be closer to the employee entrance of the building than other parking spaces, with the exception of ADA accessible parking spaces.
9. 
Sites that are adjacent to existing or planned transit stops or are in the General Commercial (C-1) and Commercial Mixed Use (C-MU) districts are subject to maximum off-street vehicle parking requirements. The maximum number of off-street vehicle parking spaces allowed per site shall be equal to the minimum number of required spaces, pursuant to Table 16.128.030.A, multiplied by a factor of:
a. 
1.2 spaces for uses fronting a street with adjacent on-street parking spaces; or
b. 
1.5 spaces, for uses not fronting a street with adjacent on-street parking; or
c. 
A factor determined according to a parking analysis prepared by a qualified professional/registered engineer and submitted by the applicant.
10. 
The applicant may propose a parking space standard that is different than the standard in Table 16.128.030.A, for review and action by the Community Development Director through a variance procedure, pursuant to Chapter 16.272. The applicant's proposal shall consist of a written request and a parking analysis prepared by a qualified professional/registered engineer. The parking analysis, at a minimum, shall assess the average parking demand and available supply for existing and proposed uses on the subject site; opportunities for shared parking with other uses in the vicinity; existing public parking in the vicinity; transportation options existing or planned near the site, such as frequent transit service, carpools, or private shuttles; and other relevant factors.
The Community Development Director may reduce or waive the off-street parking standards for sites with one or more of the following features:
a. 
Site has a transit stop with existing or planned frequent transit service (30-minute headway or less) located adjacent to it, and the site's frontage is improved with a transit stop shelter, consistent with the standards of the applicable transit service provider: Allow up to a 20% reduction to the standard number of automobile parking spaces;
b. 
Site has dedicated parking spaces for carpool/vanpool vehicles: Allow up to a 10% reduction to the standard number of automobile parking spaces;
c. 
Site has dedicated parking spaces for motorcycle and/or scooter or electric carts: Allow reductions to the standard dimensions for parking spaces and the ratio of standard to compact parking spaces;
d. 
Available on-street parking spaces adjacent to the subject site in amounts equal to the proposed reductions to the standard number of parking spaces.
e. 
Site has more than the minimum number of required bicycle parking spaces: Allow up to 10% reduction to the number of automobile parking spaces.
f. 
The property is located in the downtown area as defined by the intersection of E Harbor Drive, S Main Avenue and 4th Street.

B. 
Parking Location and Shared Parking.
1. 
Location. Vehicle parking is allowed only on approved parking shoulders (streets), within garages, carports and other structures, or on driveways or parking lots that have been developed in conformance with this Code. Parking and loading areas shall not be located in required yards adjacent to a street unless otherwise specifically permitted in this ordinance. Side and rear yards that are not adjacent to a street may be used for such areas when developed and maintained as required in this chapter. See also Chapter 16.120, Access and Circulation.
2. 
Off-Site Parking. Except for single-family, two-family, and three-family dwellings, the vehicle parking spaces required by this chapter may be located on another parcel of land, provided the parcel is within 200 feet or a reasonable walking distance of the use it serves. The distance from the parking area to the use shall be measured from the nearest parking space to a building entrance, following a sidewalk or other pedestrian route. The right to use the off-site parking must be evidenced by a recorded deed, lease, easement, or similar written instrument.
3. 
Mixed Uses. If more than one type of land use occupies a single structure or parcel of land, the total requirements for off-street automobile parking shall be the sum of the requirements for all uses, unless it can be shown that the peak parking demands are actually less (i.e., the uses operate on different days or at different times of the day). In that case, the total requirements shall be reduced accordingly.
4. 
Shared Parking. Required parking facilities for two or more uses, structures, or parcels of land may be satisfied by the same parking facilities used jointly, to the extent that the owners or operators show that the need for parking facilities does not materially overlap (e.g., uses primarily of a daytime versus nighttime nature), and provided that the right of joint use is evidenced by a recorded deed, lease, contract, or similar written instrument establishing the joint use.
5. 
Availability of Facilities. Owners of off-street parking facilities may post a sign indicating that all parking on the site is available only for residents, customers and/or employees, as applicable. Signs shall conform to the standards of Chapter 16.144.
C. 
Parking Stall Standard Dimensions and Compact Car Parking. All off-street parking stalls shall be improved to conform to City standards for surfacing, stormwater management, and striping. See Section 16.120.020 for parking lot construction standards. Up to 40% of the required spaces may be sized to accommodate compact cars. Standard parking spaces shall conform to the dimensions in Figure 16.128.030.C. Disabled person parking spaces shall conform to the standards (and dimensions) in this section.
