8. Open Space Design Potential Barriers Possible Resolutions Smaller lots are less marketable Many studies indicate that open space designs can save in construction costs while having a higher market value Developers may be discouraged from using open space design because it requires a special exception or additional review process Communities can revise their subdivision or zoning ordinances to make open space design by-right
9. Millcreek subdivision in Lancaster, PA uses narrow streets, shorter setbacks, and sidewalks on one side of the street only to reduce impervious cover and conserve natural areas
10. Open space was conserved at the Millcreek subdivision by clustering lots
14. Minimize Clearing Potential Barriers Possible Resolutions Preservation of trees during construction is prohibitively expensive. Minimizing clearing during construction and reduce earth movement and erosion and sediment control costs by up to $5,000/ acre (Delaware DNREC, 1997) Vegetation near homes can be a fire risk. In areas where clearing is required around a house, minimization of the entire site can still be achieved. This can be a challenge in wildfire areas. Greater clearing and grading maybe required to reduce risk of fires.

19. Protect Trees During Construction Potential Barriers Possible Resolutions Additional cost of saving a tree outweigh benefits. Property values increased by 6-15% on both residential and commercial sites (Morales, 1980 and Weyerhauser, 1989) Single family homes in Athens, GA with an average of 5 trees/ home sold for 3.5-4.5% more than houses without trees (National Arbor Day Foundation, 1996)

23. As much open space as possible should be retained in a natural condition and lawns and playgrounds may not be counted towards this portion
24. The Cost of Open Space Management Open Space Management Strategy Annual Maintenance Cost Natural open space only minimum maintenance trash/debris cleanup $75/acre Lawns regular mowing $240-270/acre Passive recreation $200/acre
25. Open Space Management Potential Barriers Possible Resolutions Common areas, stormwater management, and other facilities can be expensive. Many of these costs can be offset by reducing the amount of paving on a site. Community association management of open space areas are not reliable Other options for management include donation to a land trust, conservation easements, and other strategies for maintaining the viability of community associations
41. Plant Trees at Development Sites Potential Barriers Possible Resolutions Trees not allowed in STPs Cappiella, et al (2005) provides guidance on incorporating trees into STP design Subdivision standards specify narrow tree lawn and parking lot islands that will not support large healthy trees Use expanded tree pits to allow shared rooting space. Communities can revise codes to require larger planting spaces Trees not allowed because of overhead wires Communities can revise codes to allow utilities to be placed underground
