(a) Implementation. (1) When the UDV method is 

 used for economic evaluations, planners will select 

 a specific value from the range of values provided 

 in the most current published schedule. Application 

 of the selected value to estimated annual use over 

 the project life, in the context of the with- and with- 

 out-project framework of analysis, provides the esti- 

 mate of recreation benefits. 



(2) Two categories of outdoor recreation days, 

 general and specialized, may be differentiated for 

 evaluation purposes. "General" refers to a recrea- 

 tion day involving primarily those activities that are 

 attractive to the majority of outdoor users and that 

 generally require the development and mainte- 

 nance of convenient access and adequate facilities. 

 "Specialized" refers to a recreation day involving 

 those activities for which opportunities in general 



are limited, intensity of use is low, and a high 

 degree of skill, knowledge, and appreciation of the 

 activity by the user may often be involved. 



(3) Estimates of total recreation days of use for 

 both categories, where applicable, will be devel- 

 oped. The general category comprises the great 

 majority of all recreation activities associated with 

 water projects, including swimming, picnicking, 

 boating, and most warm water fishing. Activities 

 less often associated with water projects, such as 

 big game hunting and salmon fishing, are included 

 in the specialized category. A separate range of 

 values is provided in a conversion table (Table VIII- 

 3-1) for each category and for fishing and hunting 

 to facilitate adoption of a point system in determin- 

 ing the applicable unit values for each individual 

 project under consideration. 



Note.— Adjust dollar value for subsequent years to reflect changes in the Consumer Price Index after July 1, 1982. 



(4) When employing this method to determine 

 recreation benefits, select appropriate values from 

 the range of values provided. If evidence indicates 

 a value outside the published range, use the TCM 

 or CVM method. 



(5) In every case, planners are expected to ex- 

 plain the selection of any particular value. To assist 

 in explaining a specific value, a point rating method 

 may be used. The method illustrated here contains 

 five specific criteria and associated measurement 

 standards designed to reflect quality, relative scar- 

 city, ease of access, and esthetic features. Since 

 the list of criteria and weights assigned may vary 

 with the situation, public involvement should occur 

 in the value determination process. Planners in the 

 various agencies are also expected to make appro- 

 priate use of studies of preferences, user satisfac- 

 tion, and willingness to pay for different characteris- 

 tics. When these studies are used, particular efforts 

 should be made to use estimates derived else- 

 where from applications of the TCM and CVM tech- 

 niques, to support the value selected. 



(i) General recreation (Table VIII-3-2). Activities 

 in this category are those associated with relatively 



intensive development of access and facilities as 

 compared to the specialized recreation category. 

 Generally, progressively higher physical standards 

 for each unit of carrying capacity is involved in se- 

 lecting higher unit values, and these may be ac- 

 companied by larger related nonproject costs. 



(ii) Specialized recreation (Table VIII-3-3). (A) 

 This category includes those activities whose 

 values are generally lowered, if not actually ex- 

 cluded, by the type of development that enhances 

 activities in the general recreation category. Thus, 

 extensive or low density use and development con- 

 stitutes the higher end of this range of values (e.g., 

 big game hunting and wilderness pack trips). Also 

 included in the upper end of the range are relatively 

 unique experiences such as inland and marine fish- 

 ing for salmon and steelhead, white water boating 

 and canoeing, and long-range boat cruises in areas 

 of outstanding scenic value. Examples of activities 

 to which values at the lower end of the range 

 would be assigned include upland bird hunting and 

 specialized nature photography.
