4. Sustainability We do not inherit the earth from our ancestors, we borrow it from our children.

5. Sustainability The design, construction, and maintenance practices that meet the needs of the present without compromising future generations

6. The Sustainable Sites Initiative™ Healthy ecosystems provides goods and services of benefit to humans and other organisms. • http://www.sustainablesites.org/

7. The Sustainable Sites Initiative™ • The Sustainable Sites Initiative™ (SITES™) is an interdisciplinary effort by the American Society of Landscape Architects, the Lady Bird Johnson Wildflower Center at The University of Texas at Austin and the United States Botanic Garden to create voluntary national guidelines and performance benchmarks for sustainable land design, construction and maintenance practices

8. The Sustainable Sites Initiative™ The US Green Building Council to incorporate Sustainable Sites benchmarks into future versions of LEED (Leadership in Energy and Environmental Design)

9. The Sustainable Sites Initiative™ Hydrology • Water is the driving force behind many initiatives • Demand for water in US has tripled in last 30 years

10. The Sustainable Sites Initiative™ Hydrology Manage and clean water on-site • Design a site to capture, slow, and treat stormwater runoff by reducing impervious surfaces • Bioretention, rain gardens, wetlands, green roofs, and bioswales

11. The Sustainable Sites Initiative™ Hydrology Design stormwater features to be accessible to site users • Provide calming views and spaces for restoration

12. The Sustainable Sites Initiative™ Hydrology Minimize potable water for irrigation  • Rainwater from rooftops and graywater • Smart controllers lowers water use

13. The Sustainable Sites Initiative™ Hydrology • In Portland, Oregon, nearly 49,000 downspouts have been disconnected, removing more than 1.2 billion gallons of stormwater per year from the combined sewer system • A 2,500-acre wetland in Georgia saves $1 million in water pollution abatement costs each year

14. The Sustainable Sites Initiative™ Hydrology • NYC acquired thousands of acres of watershed lands, $1.5M over 10 years, saved about $5M in construction costs of water filtration plant and $300M in annual operations

15. The Sustainable Sites Initiative™ Soils • Healthy soils allow rainwater to penetrate, preventing excess runoff, sedimentation, erosion, and flooding • Clean, store, and recharge groundwater

16. The Sustainable Sites Initiative™ Soils Protect healthy soils  • During construction, retain topsoil and minimize soil disturbance

17. The Sustainable Sites Initiative™ Soils Use plant trimmings as compost • Compost supplies slow-release nutrients

18. The Sustainable Sites Initiative™ Soils Improve health of degraded soils  • Address soil compaction, organic matter levels, and the balance of soil organisms in existing soils

19. The Sustainable Sites Initiative™ Vegetation • Stormwater management, filtration, and groundwater recharge • Vegetation maintains soil structure, contributes to soil organic matter, and prevents erosion

20. The Sustainable Sites Initiative™ Vegetation Protect and use existing vegetation • Design the site to minimize disruption to existing habitats

21. The Sustainable Sites Initiative™ Vegetation Regional vegetation • Use native and appropriate non-native plants adapted to site conditions • Avoid invasive plants

22. The Sustainable Sites Initiative™ Vegetation Lower energy consumption • Strategic locations around buildings • Reduce urban heat island effects

23. The Sustainable Sites Initiative™ Materials • Reuse as much of the existing site materials as practical

25. The Sustainable Sites Initiative™ Materials Purchase local and sustainably-produced • For lumber, choose certified, sustainably harvested wood • Well managed forestry practices or reclaimed wood • Forest Stewardship Council logo

26. The Sustainable Sites Initiative™ Materials Purchase local and sustainably-produced • Recycled materials • Stone • Timber • Crushed glass

27. Plastic Plastic lumber, 100% recycled plastic

28. Plastic Baleboard • Recycled bale wrap and greenhouse plastic

29. Plastic Composite wood • Recycled plastic and waste wood fibers

30. Plastic Plasphalt • Plasphalt™ is a combination of recycled plastic and asphalt • More resistant road material

31. Rubber • Mulch • Playground has no metal (Playsafe)

32. Rubber • Mulch

33. Rubber • The groups claims are brought on by recent findings of the Connecticut Agricultural Experiment Station, which suggest that the chemical, butylated hydroxyanisole, found in reused tire mulch, is a potential carcinogen and skin irritant. The research has been backed by spokespersons at the Mt. Sinai Hospital in New York, who claim there has been an increase in skin infections from children playing on synthetic turf fields.

34. Rubber Crumb rubber • Common synthetic turf topdressing

35. Rubber Crumb rubber • Concern over harmful leachates • Water and environmental

36. Toxic materials • PVC considered dangerous plastic to produce (14 billions pounds annually)

37. Toxic materials • Solid PVC is relatively harmless, other stages of life cycle raise major environmental concerns

38. Toxic materials • CA require vinyl garden hoses warning (vinyl is essentially PVC with plasticizers)

39. Toxic materials • This product contains chemicals known to cause cancer and birth defects or reproductive harm. Do Not Drink From This Hose.

40. Toxic materials • PVC not recyclable • Alternatives: PE, ABS, HDPE

41. Toxic materials • Wood preservatives are designed to kill micro-organisms (prevent decay) • Chromate copper arsenic (CCA) banned in 2004

42. Toxic materials • CCA was replaced by ACQ, alkaline copper quat (quaternary ammonia) • ACQ copper not as fixed, more susceptible to leaching

43. Toxic materials • Using naturally resistant wood: tropicals (Ipe, teak), cedar, or cypress

44. Sustainable Substitute • http://www.amerinursery.com/blog-1439.aspx • Black locust suggested by some to replace IPE (considered unsustainable)

45. The Sustainable Sites Initiative™ Human Health & Well-being Focus on natural views

46. The Sustainable Sites Initiative™ Human Health & Well-being Provide spaces for mental restoration, social interaction, and physical activity
