This manual collects experiences of successful linkage programs to demonstrate the promise of linkage and to show its limits and risks. It is intended to help communities assess the capacity of linkage to meet their needs and evaluate the considerable commitment this strategy requires. (In linkage programs, developers who receive community approval and public aid for a development project are required to provide some form of benefit to the community.) Chapter I is an introduction that considers the political and legal implications of linkage, preconditions, and dangers. Chapter II traces the legal background and status of linkage. Chapters III-VII examine the development, implementation, and enforcement of linkage programs providing the following: (1) employment and training opportunities through First Source programs under which employers are asked or required to use the city's employment and training office or community organizations as their first source for job applicants; (2) minority and women-owned business support; (3) affordable housing through housing trust funds; (4) equity participation partnerships; and (5) community facilities and social and human services. Each of the seven chapters is followed by three appendixes that provide references to recommended further readings and technical assistance providers, contain notes on sources used in researching the chapter content, and contain sample documents that are models suitable for adaptation. A list 41 background readings is provided. (YLB)
