The California Conservation Corps (CCC), comprised of both residential and non-residential centers, was established in 1977 to conduct useful conservation work and provide youth between the ages of 18 and 23 with valuable work experience. This report uses data from 1983 and 1984 to assess the value of the work done by the CCC. It contains the following information: (1) a description of the CCC's projects; (2) an explanation of methods used for valuing work, with a discussion of the strengths and weaknesses of each; (3) the results of five different estimates of the value of CCC work, value/cost ratios, and an interpretation of findings; (4) conclusions and recommendations; and (5) a technical appendix describing the development of the willingness-to-pay estimate, derived from the environmental economics approach to valuing work, with a discussion of that approach. Findings of the five attempts to value the CCC's work were inconsistent, even when similar approaches were used. Estimates of the value of the CCC's work for the past several years ranged from approximately $16 million to $308 million. Value/cost ratios ranged from 0.60 to 7.0. The findings are controversial because: (1) none of the analyses is of the methodological or theoretical quality from which the evaluating agency would ordinarily draw firm conclusions; and (2) findings value the work much higher than that of other similar projects.
