(ii) Account for site transfers in choosing unit day 

 values. An example of a point rating table that does 

 this and further discussion of unit day value selec- 

 tion can be found in Appendix 3 of this section. Ap- 

 pendix 3 is provided for background information. 

 Development and use of techniques more refined 

 than those presented in this Appendix are encour- 

 aged. 



2.8.11 Evaluation procedure: Forecast 

 recreation use diminished with project. 



Using the appropriate method described in 2.8.9, 

 forecast the recreation resource uses that would be 

 diminished due to physical displacement expected 

 because of the plan or project. 



scribed in 2.8.2, estimate the value of the recrea- 

 tion uses that would be diminished by the physical 

 displacement expected to occur as a result of the 

 plan or project. In determining project net benefits, 

 account for changes in recreation use of an exist- 

 ing resource and/or project as a result of transfers 

 to the plan or project under study. 



2.8.13 Evaluation procedure: Compute net 

 project benefits. 



Compute the project benefit as the difference be- 

 tween the gross value of recreation use as estimat- 

 ed in 2.8.9 and the value of recreation use dimin- 

 ished as estimated in 2.8.12. However, if excess 

 capacity for any activity exists in the study area, 

 benefits are the user cost savings plus the value of 

 any qualitative differences in recreation.

Appendix 1 to Section VIII— Travel Cost 

 Method 



The basic premise of the travel cost method 

 (TCM) is that per capita use of a recreation site will 

 decrease as the out-of-pocket and time costs of 

 traveling from place of origin to the site increase, 

 other things remaining equal. The method consists 

 of deriving a demand curve for a recreation site by 



using the variable costs of travel and the value of 

 time as proxies for price. By use of data collected 

 from users of existing sites, the travel cost method 

 permits development of (1) estimated use of the 

 proposed site; (2) a per capita demand function for 

 recreation at the site; and (3) an estimate of the 

 NED recreation benefits of the site. The travel cost 

 procedure consists of two steps: estimating use 

 and deriving a demand cun/e.
