A study of the impacts of greenbelts on property value for one neighborhood was approximately $5.4 million greater than if there had been no greenbelt. This results in approximately $500,000 additional potential property tax revenue annually. (Correll, Lillydahl, and Singell, 1978).
From 1980 to 1990, those who said they would pay extra for greenbelts and parks in their neighborhood rose from 16 percent to 48 percent (Rocky Mountain Research Institute, 1991).
In two 1995 surveys by American LIVES, Inc and InterCommunications Inc, homebuyers indicated that natural open space and walking and biking paths were among the top four most important features in a residential neighbourhood (Warrick and Alexander, 1997).
