We need progress on all 3 legs, but climate
policy discussions have mostly ignored VMT
3VMT growing faster than population
Growth of VMT, vehicle registrations, and
population in the United States relative to 1980
values
4Why do we drive so much?
Does it look like we have any other choice?
5If Trends Continue
- The total amount of miles we drive will grow 59
percent - From 2005-2030
- Source U.S. Dept. of Energy
6Bottom line of the research
- Compact, walkable neighborhoods cut VMT
- by an average of
- 30 percent
- (With higher ranges possible)

8People in walkable neighborhoods drive less
- People who live in neighborhoods with the lowest
walkability drive - 39 miles more per person each weekday
- 30 more than those with the highest walk-
ability. - On weekends, those in most walkable drive 40
less - SMARTRAQ report, 2007
9Projected 2030 Savings from Compact Development
- Shifting 60 of new growth to compact
- patterns
- 85 million metric tons of CO2 in 2030
- Would be equal to a 28 increase in CAFE
standards to 32 mpg in 2020 (but benefits extend
well beyond) - Fuel cost savings in 2030 24 billion
- Cumulative 250 billion
10Growing Cooler What it means
- Meeting the growing demand for
- conveniently located homes in
- walkable neighborhoods could
- significantly reduce the growth
- in the number of miles
- Americans drive, shrinking the
- nations carbon footprint while
- giving people more housing
- choices

12The 5D Variables
- Density
- Diversity (of land use mix)
- Design
- Destination (accessibility)
- Distance (to transit)
13Is there a market for walkable neighborhoods?
- Survey
- 6 in 10 prospective homebuyers chose walkable
neighborhoods with less time spent driving - African-Americans and Hispanics even more likely
to prefer compact neighborhoods - Source 2004 poll by National Association of
Realtors and Smart Growth America
14Balancing Our Budget
- Compact development reduces infrastructure costs
and saves money. - Average annual cost to service a new family of
four (police, fire, highway, schools and sewer) - Compact suburban Shelby County, KY 88.27
- Sprawling Pendleton County, KY 1,222.39

- 73.3 of patrons walk to transit over 58,000
trips daily - 38 of residents near stations take transit to
work - 12 of Arlington County households dont own
cars--triple the regional average - Corridor produces 32.8 of the Countys real
estate tax revenue from 7.6 of its land area - Arlington has the lowest property tax of any
major jurisdiction in Northern Virginia - Source

18Priority Inventment Areas
- Affordable housing
- Purchase costs no more than 28 and rental costs
no more than 30 of - 80 of area median income - Traditional neighborhood design design and
appearance so that functions like traditional
neighborhood or town. - Reasonably high densities
- Mixture of residential and commercial uses
- Range of single and multi family housing types
- Street connectivity within development and
surrounding
19PIA Definitions
- Market-based incentives encourage private
developers to meet goals. Includes - Density bonuses
- Relaxed regulations
- Reduced or waived fees
- Fast-track permitting
- Design flexibility
20Codes/Zoning
- Smart Neighborhoods model overlay ordinances
designed to help local governments encourage
mixed-use and compact development within the
framework of conventional zoning. - Maryland Smart Neighborhoods and Infill
Development Models -
- LEED-ND
- Mixed-Use Zoning Districts
- Mixed-use overlay aimed at encouraging
market-driven, mixed-use development and
higher-density residential projects. (ex City of
Anaheim, CA). - Overlay Zones
- Help to establish template for high-density,
mixed-use while retaining existing zoning - For established single-use areas with
predominately commercial, office, and retail uses
to add housing element while maintaining code
requirements - Incentive-base Zoning (University Neighborhood
Overlay in Austin, TX) - Small-lot Subdivision Ordinance
- Streamlines subdivision and entitlement process
to encourage infill development (City of Los
Angeles)
21SMART-CODERural-Urban Transect The zones
within the SmartCode are designed to create
complete human habitats ranging from the very
rural to the very urban. Where conventional
zoning categories are based on different land
uses, SmartCode zoning categories are based on
their rural-urban character. All categories
within the SmartCode allow some mix of uses.
SmartCode zoning categories ensure that a
community offers a full diversity of building
types, thoroughfare types, andcivic space types,
and that each has appropriate characteristics for
its location.
22Central PetalumaSmartCode
- Citys vision system for ensuring that the
design of the public realm and the design of
private buildings are rigorously coordinated, and
are focused on the pedestrian experience. - Pedestrian-oriented public-streets, plazas,
squares and riverfront walks, lined with
mixed-use, pedestrian-oriented buildings.
23Central PetalumaSmartCode
- To develop new, mixed-use neighborhoods with the
following characteristics - 5-minute walking distance from edge to center
- Mixture of land uses includes shops, workplaces,
residences, and civic buildings in proximity. - Variety of thoroughfares that serve the needs of
pedestrians, cyclists and automobiles equitably - Public open spaces that provide places for
informal social activity and recreation and - Building frontage that define the public space of
each street. - http//cityofpetaluma.net/cdd/cpsp.html
24Smart Neighborhoods
- Relatively self-contained new communities with
a compact mix of residential, commercial,
employment/office, and civic land uses and range
of housing choices, with a design that fosters
pedestrian and bicycle activity, public safety,
environmental protection, long-term investment,
efficient use of infrastructure, and efficient
provision of public services. - Large infill and greenfield sites, located
within priority funding areas.
25Smart Neighborhoods
- Efficient use of infrastructure
- 2. Socioeconomic diversity
- 3. Transportation choice
- 4. Environmental quality
- 5. Sustained economic health
- 6. Sense of community
- 7. Logical extension and integration of
communities
26Density Tools
- Development Rating Systems
- score-cards, decision-making tool
- - Livable Communities Coalition in Atlanta
- - Smart Growth Criteria Matrix in Austin. TX
- Financial Incentives
- Mixed-use projects carry the dual burdens of
decreased certainty of approval and perceived
increase in risk. In order to encourage mixed-use
development, jurisdictions need to provide
developers with increased certainty of approval,
incentives, or a reduced share of the costs of
public amenities.
27INCENTIVES FOR DEVELOPERS
- 1. Property tax abatements
- 2. Grants
- 3. Low interest loans
- 4. Preferential fee structuring
- 5. Rebate or payback programs to ensure
contiguous development. - 6. Priority status for development review
- 7. Align capital improvement program (CIP) to
ensure the provision of adequate public
facilities in smart neighborhood areas.
