Usgbc Emerald Coast Presentation

  1. 1. New and Old Urbanism: Designing Communities for People and Nature Christian Wagley
  2. 2. Land development is occurring at a far higher rate than population growth, resulting in sprawl. In the nation’s 34 metropolitan areas with populations greater than one million people, between 1950 and 1990 the population increased 92.4%, while the urbanized land area grew by 245%, or 2.65 times the population growth rate.

  3. 3. From 1990 to 1996, Pensacola's urbanized land area has exploded, growing from 174 square miles to 337 square miles, a nearly 95 percent increase. In the same time period, the area's population only increased from 270,000 to 280,000. Those 10,000 new citizens of the Pensacola metro region overlay a land area increase of 163 square miles, which translates into roughly 63 people per square mile. Compared to Pensacola's 1990 population density of 1,551 persons per square mile, this new growth pattern epitomizes sprawl. Source: 1998 Sierra Club Sprawl Report
  4. 4. We drive up and down the gruesome, tragic suburban boulevards of commerce, and we're overwhelmed at the fantastic, awesome, stupefying ugliness of absolutely everything in sight -- the fry pits, the big-box stores, the office units, the lube joints, the carpet warehouses, the parking lagoons, the jive plastic townhouse clusters, the uproar of signs, the highway itself clogged with cars -- as though the whole thing had been designed by some diabolical force bent on making human beings miserable. And naturally, this experience can make us feel glum about the nature and future of our civilization. James Howard Kunstler, Home from Nowhere, 1996
  5. 5. air pollution
  6. 6. water pollution
  7. 7. global warming
  8. 8. habitat alteration
  9. 9. The Congress for the New Urbanism views disinvestment in central cities, the spread of placeless sprawl, increasing separation by race and income, environmental deterioration, loss of agricultural lands and wilderness, and the erosion of society's built heritage as one interrelated community-building challenge. Charter of the New Urbanism

  11. 11. mixed-use
  12. 12. walkable
  13. 13. Comparing Transportation and Operating Energy Use for an Office Building Source: Environmental Building News, September 1, 2007
  14. 14. For an average new office building built to code, transportation accounts for more than twice as much energy use as building operation.
  15. 15. human- scale, people- friendly
  16. 16. street grid
  17. 17. beauty
  18. 18. environmental benefits
  19. 19. “The results of this analysis suggest that strong support for infill development can be one of the most effective transportation and emission- reduction investments a region can pursue.”
  20. 20. “Many communities assume that low-density development automatically protects water resources. This study has shown that this assumption is flawed and that pursuit of low-density development can in fact be counterproductive, contributing to high rates of land conversion and stormwater runoff and missing opportunities to preserve valuable land within watersheds.”
  21. 21. “Curbing emissions from cars depends on a three- legged stool: improved vehicle efficiency, cleaner fuels, and a reduction in driving...The research shows that one of the best ways to reduce vehicle travel is to build places where people can accomplish more with less driving.”
  22. 22. Florida 2060: A Population Distribution Scenario for the State of Florida Promoting higher-density infill development, statewide high-speed rail, and local transit could accommodate population growth to 2060 in a way that reduces land loss to development from 7 million acres to 1.6 million acres.

  24. 24. Where is the new in new urbanism?
  25. 25. Why aren’t we building more sustainable communities in the form of traditional neighborhoods? Communities that use less water and energy, generate less stormwater runoff, reduce air and water pollution, and preserve open space…
  26. 26. It’s illegal to build traditional neighborhoods in most communities in America
  27. 27. Form-based codes support these outcomes: walkable and mixed-use neighborhoods, transportation options, conservation of open lands, local character, housing diversity, and vibrant downtowns. Form-based codes discourage these outcomes: sprawl development, automobile dependency, loss of open lands, monotonous subdivisions, deserted downtowns, and unsafe streets and parks.
  28. 28. We cannot create truly green buildings, or a truly green community, until we change the rules of development .
  29. 29. Are you ready to change the rules of development and create a healthy, vibrant, sustainable community?
