2.8.3 Planning setting. 



(a) General. Determine changes in recreation use 

 and value resulting from alternative plans through 

 analysis of without-project and with-project condi- 

 tions in the study area over the prescribed period of 

 analysis. 



(b) Without-project condition. The without-project 

 condition is the pattern of recreation activity expect- 

 ed to prevail over the prescribed period of analysis 

 in the absence of the recreation project or plan. 

 The without-project condition includes existing 

 water and related land recreation resources, and 

 projects and additional recreation resources cur- 

 rently being developed or both authorized and likely 

 to be developed during this period. 



(c) Witti-project condition. The with-project condi- 

 tion is the pattern of recreation activity expected to 

 prevail over the prescribed period of analysis with a 

 recreation plan or project. Recreation resources in- 

 cluded in the without-project condition provide the 

 basis for the with-project condition. Analysis of the 



with-project condition considers recreation opportu- 

 nities that will be diminished in quality or quantity 

 because of project development and operation. 

 This will be accomplished in assessing the use of 

 the proposed recreation development. 



2.8.4 Evaluation procedure: General. 



Use th'e following procedure to determine the 

 benefit from recreation resource use with a plan or 

 project. (See Figure 2.8.4.) The benefit is based on 

 the gross value of recreation use of the resource 

 for the with-project condition less the gross loss in 

 recreation use caused by the project or plan. The 

 recreation benefit is measured in nine steps. The 

 level of effort expended on each step depends on 

 the nature of the proposed improvement, the state 

 of the art for accurately refining the estimate, and 

 the sensitivity of project formulation and justification 

 to further refinement.
