This document contains (1) a monograph investigating and describing conditions under which it is cost-beneficial to operate an enriched YCCIP (Youth Community Conservation and Improvement Project) design and (2) a guidebook to work project enrichment. The first sections of the monograph focus on the attributes of an enriched YCCIP activity in Bellingham, Washington, and analyzes enrichment, its costs, risks, and consequences. Subsequent sections combine a description of a parallel, non-enriched labor-intensive comparison site with a comparative evaluation of the parallel projects. Final sections draw summary conclusions and provide a description of important, probably necessary, conditions which were present in the successfully implemented enriched project's program environment. The three-part guidebook begins with a discussion of the Civilian Conservation Corps, the first enriched labor-intensive work project. Parts 2 and 3 have as their subject the history of the successful enriched project in Bellingham--Whatcom Creek Heritage Park and Maritime Heritage Center Project. Part 2 gives a synopsis of the comparative analysis of this project and a parallel work project to ascertain relative costs and benefits of operating an enriched project design. Part 3 lists and discusses seventeen steps for the development of successful "sweat" (labor intensive) work projects. (YLB)
