  1. Getting to Right-Sized Parking Innovative Approaches to the Traditional Supply/ Demand Mentality

  2. What is Right Sized Parking? • Predicting parking needs based on actual data about a site or community, rather than using predictive generation characteristics. • Studies have shown that the old methods: • Increase vehicle ownership • Increase vehicle miles traveled • Increase congestion • Increase housing costs

  3. What Are The Consequences?

  4. Who Says How Much?

  5. City/County Parking Ordinances • Apply generic land use parking ratios • Broad category types • Based on approximations or what other communities are doing

  6. National Industry Standards • Apply generic land use parking ratios • Generic category types are applied as “one-size-fits-all” • Based on limited research from suburban developments

  7. Introducing Shared Parking • Finally starting to realize parking is a system • Multiple land uses and users can utilize shared pool of spaces • Still relies heavily on generic industry land use standards

  8. Can We Go Further? Why do we continue to treat these uses/users the same?

  9. Can We Go Further? Why do we continue to treat these uses/users the same? We need methods that allow us to predict parking demands for our actual uses and users, with variations for location, relationship, and context within our communities. We need methods that allow us to predict parking demands for our actual uses and users, with variations for location, relationship, and context within our communities.

  10. Traditional Supply/Demand

  11. A New Approach

  12. Let’s Look At An Example • 300 room hotel • 30,000 sf retail • 20,000 sf restaurant • How much parking do we need?

  13. The Traditional Approach Peak Hour SpacesUse Size Rate Factor RequiredHotel 300 1.15 0.9 311Retail 30,000 3.6 0.8 87 Restaurant 20,000 18 1.0 360 The total parking demand is: 758 spaces

  14. The Park+ Approach

  15. The Park+ Approach Peak Hour SpacesUse Size Rate Factor RequiredHotel 300 0.5 - 150Retail 30,000 0.8 - 24 Restaurant 20,000 6.4 - 128 The total parking demand is: 302 spacesSavings of 456 spaces

  16. The Park+ Approach
