The Sustainable Sites Initiative

On Friday, July 9th, the Central Texas American Planning Association (APA) learned by the Sustainable Sites Initiative from the Lady Bird Johnson Wildflower Center's own Dr. Steve Windhager.

The goal of Sustainable Sites Initiative is to do for landscape design what LEED certification has done for building design. Under the Sustainable Sites Initiative, sites qualify for certification (1 star, 2 star, 3 star, and 4 star) based on a 250 point scale. As of June 2010, 174 pilot projects were started under the Sustainable Site Initiative.

This quick summary doesn't do Dr. Windhager's presentation justice, so check out his presentation complete with interesting facts about the ROI of urban forests and how New York street trees provide climate moderating benefits to the tune of $27.8 million.

The Sustainable Sites Initiative

  1. 1. SUCCESS of GREEN BUILDING The construction market accounts for 13.4% of the U.S. GDP. Source: Department of Commerce (2008). Annual Value of Construction Put in Place. The value of green building construction is projected to increase to $60 billion by 2010 and over $100 billion by 2013. Source: McGraw-Hill Construction (2008). Key Trends in the European and U.S. Construction Marketplace: SmartMarket Report. Since 2000, USGBC’s membership has more than quadrupled. Source: U.S. Green Building Council, 2009

  4. 4. GREEN DOES NOT EQUAL SUSTAINABLE
  5. 5. LINKING LANDSCAPES TO SUSTAINABILITY… 25 to 50% of electricity used by US cities is consumed by municipal water and wastewater treatment. Waterand Energy Technology Team at Lawrence Berkeley National Laboratory (2007) Water shortages & drought increasing across US. NASA Earth Observatory (2008) © 2009 Sustainable Sites Initiative
  6. 6. LINKING LANDSCAPES TO SUSTAINABILITY… 30% to 65% of water used daily by a family of four is for landscape irrigation. U.S. Environmental Protection Agency, “ Outdoor Water Use in the United States”, 2007 Combine sewer overflows result in sewage and large volumes of storm water containing pathogens, solids, debris and toxic pollutants being discharged into surface water. U.S. Environmental Protection Agency, “ Report to Congress on Impacts and Control of Combines Sewer Overflows and Sanitary Sewer Overflows”, 2004
  7. 7. LINKING LANDSCAPES TO SUSTAINABILITY… 78 million households in the U.S. use home and garden pesticides. U.S. Environmental Protection Agency (EPA). 2004. Pesticides Industry Sales and Usage: 2000 and 2001 Market Estimates. EPA-733-R-04-001 Soils that are compacted during site preparation and construction lose the ability to absorb storm water and supply plant roots with air and water Breland and Hansen, 1996 Source: James Urban
  8. 8. LINKING LANDSCAPES TO SUSTAINABILITY… Disposing of organic materials in Texas landfills costs more than $150 million a year and consumes more than 15 million cubic yards of space. TCEQ Yardwise - Green Guide to Yard Care Yard and landscape trimmings contribute approximately 32 million tons to the municipal waste stream, representing over 13 percent of total municipal waste in the U.S. U.S. EPA, "Municipal Solid Waste Generation, Recycling, and Disposal in the United States: Facts and Figures for 2005
  9. 9. LINKING LANDSCAPES TO SUSTAINABILITY… Scientists estimate that strategically planting vegetation reduces cooling energy consumption by up to 25%. U.S. EPA – Heat Island Effect A study of street trees in New York City found that the climate moderating benefits provided by trees resulted in annual energy savings of $27.8 million, or $47.63 per tree.

  10. 10. LINKING LANDSCAPES TO SUSTAINABILITY… Minneapolis showed savings of $6.8 million in energy costs and $9.1 million in stormwater treatment and increased property values by $7.1 million as a result of street trees. McPherson 2006 Return On Investment from urban forests: •New York, NY: $5.60/$1 spent •Fort Collins, CO: $2.18/$1 spent •Glendale, AZ: $2.41/$1 spent •Charlotte, NC: $3.25/$1 spent Peper et al 2007
  11. 11. LINKING LANDSCAPES TO SUSTAINABILITY… Low Impact Development (LID) approaches to stormwater results in improved water quality as well as capital cost reduction between 15 and 80 percent. Environmental Protection Agency, “Reducing Stormwater Costs through Low Impact Development (LID) Strategies and Practices,” EPA 841-F- 07-006 (2007), http://www.epa.gov/owow/nps/lid/costs07/
  12. 12. LINKING LANDSCAPES TO SUSTAINABILITY… Beyond cost reductions, these communities also experienced “real and significant” benefits, including aesthetic amenities, improved quality of life, improved habitat, and enhanced property values.

  13. 13. WHAT IS SUSTAINABILITY? Healthy individuals participating in stable institutions Maintaining and Profitable, enhancing competitive ecosystem and enduring services businesses Sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs. Brundtland Report, Our Common Future, 1987
