Assessing Multifamily Residential Parking Demand and Transit Service

New multifamily residential developments must have an adequate number of parking spaces in order to avoid parking spillover onto adjacent streets, maintain traffic circulation, and ensure the economic success of the development. However, an overall supply of parking can encourage additional automobile travel at the expense of transit use. It is hypothesized that higher levels of transit service results in lower residential parking demand. This paper explores this hypothesis by examining the relationship between multifamily residential parking demand and transit level of service in two urban cities in King County, Washington. A combination of parking utilization counts and geographic information systems analysis were used to compare parking demand of multifamily apartment buildings and transit level of service characteristics. A Washington State Department of Licensing database for registered vehicles was assessed for its accuracy in determining parking demand. The findings were then used to analyze parking policies for each urban center for their ability to meet true parking demand. In one urban center, all parking requirements have been removed, which appears to have resulted in a supply that is close to the observed parking demand ratio. In the other urban center, the average parking supply rate is much larger than the minimum requirement, which has resulted in a higher oversupply of parking. The observed parking demand in both urban areas was lower than the ratios recommended by the Institute of Transportation Engineers. These findings indicate that collecting local, context-sensitive data on parking demand and levels of transit service can help jurisdictions and developers build parking that meets the true demand.
