All parking in the southern gateway – single-family residential zone shall be provided in accordance with the following:
A. Provide two stalls for every dwelling unit.
B. Additionally, provide either:
1. At least one additional stall on site for visitors. This stall may be part or all of a driveway; provided, that the vehicle does not impede either pedestrian or vehicular movement; or
2. For those residences that do not include on-premises space for visitor parking, provide one shared stall per three dwellings on street or within a small parking lot with no more than eight spaces. The stalls should not be more than 200 feet from the residence it serves. On-street parking spaces or joint use parking spaces may be used to meet this requirement. Visitor parking must meet ADA standards in terms of number and location of accessible parking stalls.
C. The parking requirement for the overall development may be met by counting all parking spaces in garages, driveways, parking lots, on-street parking included within the development as well as on-street parking along NE 145th Street, and NE 147th Street adjacent to the site. The applicant may apply for a parking reduction for conditions that reduce the actual parking need such as joint use, special populations, etc. The code administrator may allow a parking reduction if he or she determines that the reduction is justified by a parking occupancy analysis prepared by a licensed transportation planner with special qualifications in parking analysis.
D. The applicant shall submit to the city a traffic and parking impact analysis identifying the increases in traffic and off-site parking demand. The analysis shall be prepared by a licensed professional transportation engineer. The applicant shall be responsible for implementing both on-site and off-site mitigation measures that the code administrator determines necessary to prevent significant adverse impacts to transportation systems and the surrounding area. Specifically, necessary mitigation measures, such as on-site and off-site traffic calming measures, must be taken to prevent cut-through traffic and additional parking demand on streets in the surrounding area.
