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

Who Says How Much?

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

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

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

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

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.

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