Park Values Calculations

The categories that will be examined in this section are the Environmental, Economic, and Social areas that reflect the value of Parks and have research that relates to the macro-economic picture. The numbers generated may come from estimates and they are intended to be conservative. Even at that community residents may be surprised by the amounts that are generated. In each of the examined areas research is provided and cited that justify the values used. Within each of the larger categories are the sub-benefit areas. All of these are consistent with research conducted by NRPA.

Air Quality Benefits

1 $0.29 per tree per year - Quantifying Urban Forest Structure, Function, and Value: the Chicago Urban Forest Climate Project. 1997. (50.8M trees provided $9.2M air pollution benefit in 1991 = $0.18 cents/tree, or $0.29 by 2011)

2 $0.51 per tree per year - Houston’s Regional Forest. USDA Forest Service & Texas Forest Service study, Oct. 2005. Converted to per tree and 2011 values.

3 Acres $94.91 per acre per year - Coder, Dr. Kim D., “Identified Benefits of Community Trees and Forests", University of Georgia, October, 1996. (One hectare forest equals $136/day value of air pollution control. Converted to acre/year)

 

Water Quality Benefits

1 Acres $58.00 per acre per year - Assessing The Benefits and Costs of the Urban Forest. Journal of Arboriculture 18(5): September 1992. John F. Dwyer, E. Gregory McPherson, Herbert W. Schroeder, and Rowan Rowntree. Est. $.18 runoff savings per tree = .29/tree in 2011, or $58/acre at 200 trees/acre.

2 Acres $142.13 per tree per year - Economic Benefits of the Park and Recreation System of Mecklenburg County NC. Trust for Public Lands. 2010. Considered impervious % of parklands vs. no parks, 96% pervious parkland surfaces, 42 inches/rain/year, and 0.0344 stormwater treatment cost per cubic foot. Converted to per acre value.

3 Acres $747.71 per acre per year - Identified Benefits of Community Trees and Forests. Dr. Rim Coder, Univ. of GA. 1996. $336,000 savings per 1 sq/mi. = 640 acres or $525/acre. Converted to 2011 values.

Health Benefits

$351 and $702 values come from studies carried out in seven states (Cohen, 2005)

Mecklenburg County Data Set: 265,503 residents younger than 65 (28.8% of population) and 15,123 over 65 (1.6%) engaged actively enough in parks to cut their health costs (2010 phone survey). Total population = 920,000
