The total amount of miles we drive will grow 59 percent

Bottom line of the research l.jpg

Bottom line of the research

Compact, walkable neighborhoods cut VMT

by an average of

30 percent

(With higher ranges possible)

People in walkable neighborhoods drive less l.jpg
People in walkable neighborhoods drive less

People who live in neighborhoods with the lowestwalkability 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


Projected 2030 savings from compact development l.jpg
Projected 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


  • Growing cooler what it means l.jpg
    Growing 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

    nation’s carbon footprint while

    giving people more housing

    choices


    The 5d variables l.jpg
    The 5D Variables

    • Density

    • Diversity (of land use mix)

    • Design

    • Destination (accessibility)

    • Distance (to transit)


    Is there a market for walkable neighborhoods l.jpg
    Is there a market for walkable neighborhoods?

    Survey:

    • 6 in 10prospective 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


    Balancing our budget l.jpg
    Balancing 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

    Outcomes in arlington l.jpg
    Outcomes in Arlington

    • 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 don’t own cars--triple the regional average

    • Corridor produces 32.8% of the County’s real estate tax revenue from 7.6% of its land area

    • Arlington has the lowest property tax of any major jurisdiction in Northern Virginia

    Priority inventment areas l.jpg
    Priority 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


    Pia definitions l.jpg
    PIA Definitions

    • “Market-based incentives” – encourage private developers to meet goals. Includes:

      • Density bonuses

      • Relaxed regulations

      • Reduced or waived fees

      • Fast-track permitting

      • Design flexibility


    Codes zoning l.jpg
    Codes/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)

    SMART-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.

    Central Petaluma—SmartCode

    • City’s 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.


    Central petaluma smartcode23 l.jpg
    Central Petaluma—SmartCode

    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.

    Smart neighborhoods l.jpg
    Smart 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.


    Smart neighborhoods25 l.jpg
    Smart 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


    Density tools l.jpg
    Density 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.


    Incentives for developers l.jpg
    INCENTIVES 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.
