In 2012, Metro sponsored a study of parking ratios for multi-family developments in urban King County. By counting vehicles parked overnight, the Right-Size Parking study created a model of current parking needs and demonstrated that parking is 40% oversupplied.
Several pilot demonstration projects were developed in partnership with various cities. However, only one, in Kirkland, made recommendations for changes in policy. It hasn’t gone well. The challenges encountered point to the difficulties in reducing suburban parking requirements.
Fundamentally, right-size parking is a conservative approach. It does not defer to developers to build what the market requires. (Suburban cities are too concerned with spillover parking to be comfortable with that). Neither does it look forward to a less car-dependent future. It only brings parking minimums into line with current use.
Kirkland’s base parking requirements are high, far above even comparable suburban communities. They’re so dated that nobody remembers how they were derived. In downtown, 1 stall per bedroom is required, with a 1.3 minimum per unit. Most other neighborhoods have a 1.7 requirement per unit. Up to another 0.5 stalls per unit are required for guest parking. But overnight parking counts found just 1.27 parked vehicles per apartment. Indeed, the average multi-family unit only has 1.57 residents, so the code requires more parking than there are residents.
