Parking Barriers to Smart Growth Jeffrey Tumlin
Why is Parking Important?
Parking supply and management is the difference between smart growth and sprawl:
We need to manage and supply parking in line with broader goals
Parking consumes land
Parking is expensive

How is Parking Regulated?
Most local jurisdictions levy minimum parking requirements
Key aim: avoid spillover
Usually based on standards in neighboring jurisdictions, or derived from ITE Parking Generation

Effects of Minimum Parking Requirements
Cost
• Makes Smart Growth less financially feasible
• Housing less affordable
Land unavailable for other uses
Impacts on design and pedestrian friendliness
Generates traffic
Ample, free parking provides little incentive to use alternative modes

Parking Barriers to Smart Growth Jeffrey Tumlin
How Much is Enough?
No right answer
No such thing as set “demand” for parking:
• Pricing
• Availability
• Transportation choices
Supply is a value judgment based on wider community goals
Don’t confuse supply and availability

Parking Barriers to Smart Growth Jeffrey Tumlin
Parking Barriers to Smart Growth
1. Developers forced to provide more parking than unconstrained demand, due to:
• High minimum parking requirements
• Inflexible parking requirements
2. No incentives/requirements for developers to manage parking to support Smart Growth goals
Two Scenarios Where Parking Hinders Smart Growth

Three Broad Approaches for Local Jurisdictions
1. Tailor minimum parking requirements to match demand
2. Incentivize or require parking strategies to reduce vehicle trips and promote smart growth
3. Abolish parking requirements – let the market decide
Choice depends on local context and planning goals

Tailor Minimum Parking Requirements
Parking demand varies with geographic factors:
• Density
• Transit Access
• Income
• Household size
Cities can tailor parking requirements to meet demand, based on these factors
![Page 9: Parking Barriers to Smart Growth ABAG Technical Session: Smart Growth Strategies and Techniques for Parking February 25, 2004 Jeffrey Tumlin Nelson\Nygaard](https://reader030.vdocuments.net/reader030/viewer/2022020417/5697bf9b1a28abf838c92bf4/html5/thumbnails/9.jpg)

Local Examples
Mountain View and San Jose – parking reductions for transit oriented development
San Rafael – reduced parking requirements downtown
Menlo Park and Milpitas – reduced parking requirements for high-density housing
Palo Alto and Marin County – studies to tailor parking requirements to meet demand
Tailor Minimum Parking Requirements

Advantages:
Avoids spillover problems
Reduces impacts of minimum parking requirements
Disadvantages:
Complex to introduce effectively
Does not constrain parking demand
Sees parking requirements as a technical exercise, not a policy decision
Tailor Minimum Parking Requirements

Constrain Supply
Overall principle: encourage less auto-oriented development
Promotes self-selection – residents with fewer cars live close to transit
Different approaches:
• Parking maximums
• Requirements/incentives for demand management
Needs to be complemented with Residential Permit Parking or other strategies to stop overspill

Parking Barriers to Smart Growth Jeffrey Tumlin
Parking Maximums
Promote alternatives to the private automobile
Can tackle congestion if related to roadway capacity or mode shift goals
Maximize land area for other uses
Appropriate in areas with strong real estate market where priority is to minimize auto dependence
Examples: downtown San Francisco, Portland, Cambridge
![Page 13: Parking Barriers to Smart Growth ABAG Technical Session: Smart Growth Strategies and Techniques for Parking February 25, 2004 Jeffrey Tumlin Nelson\Nygaard](https://reader030.vdocuments.net/reader030/viewer/2022020417/5697bf9b1a28abf838c92bf4/html5/thumbnails/13.jpg)

Parking Management Strategies
Strategies to reduce parking demand:
• Pricing
• Unbundling
• Car-Sharing
• Other demand management (e.g. EcoPasses)
Strategies to reduce parking impacts:
• Shared parking
• Structured parking
• Stacked parking/parking lifts
• Design requirements (e.g. wrap parking in active uses)
Can be mandated or incentivized

Parking Barriers to Smart Growth Jeffrey Tumlin
Abolish Parking Requirements
Let developers, the public and the market decide
Create a level playing field
Needs complementary Residential Permit Parking strategy to combat overspill

Role of Transit Agencies
Revise joint development policies – particularly parking replacement
Consider the total ridership potential of the project
Housing and commercial development generate more ridership per acre than surface commuter parking
Encourage projects that minimize parking and focus on the transit resources

Parking Barriers to Smart Growth Jeffrey Tumlin
Role of Regional Agencies
Promote best practices
Follow up studies of parking demand at completed developments
Condition major transportation investments on supportive land uses policies – particularly parking
Direct TLC/HIP funds to projects that minimize parking
