Right Size Parking

Over-building of parking supply leads to increased automobile ownership, vehicle miles traveled, congestion and housing costs. In addition, it presents barriers to smart growth and efficient transit service. ULI Northwest partnered with King County Metro Transit to address the issues around multi-family residential parking supply in King County.

Right Size Parking

The supply and use of parking are influenced by — and have influences on — development practices, local policies, economic impacts on builders and households, and community goals. The supply and price of parking also have direct relationships with travel behavior. Too much parking at residential properties correlates with more automobile ownership, more vehicle miles traveled, more congestion, and higher housing costs. In addition, excess parking presents barriers to smart growth and efficient transit service.

Parking supply and pricing often have a direct impact on the ability to create compact, healthy communities. The Urban Land Institute and King County Metro Transit have an interest in encouraging land uses, policies, and development that lead to communities that can be served efficiently and effectively by transit. Locally credible and context-sensitive data on parking use allows jurisdictions in King County to:

  • Support economic development by reducing barriers to building multifamily residential developments in urban centers near quality transit infrastructure.
  • Reduce housing costs as well as household monthly expenditures, allowing a larger demographic to participate in the urban, infill housing market.
  • Encourage transit use, ridesharing, biking, and walking.
  • Reduce traffic congestion, vehicle miles traveled, and the amount of greenhouse gases produced.

ULI Northwest partnered with King County Metro Transit to address the issues around multi-family residential parking in King County. One of the result of this partnership is the King County Multi-Family Residential Parking Calculator.

On February 19, 2013, ULI Northwest hosted a luncheon on to present the parking calculator and to chat about the art and science of parking with legendary Professor of Urban Planning at UCLA, Donald Shoup and a regional panel of experts. You can read a summary of the event and review the associated materials here.
