For the National Institute of Justice, ILJ conducted a comprehensive process evaluation of the Louisville Oasis project implemented by the Oasis Institute, Housing Authority of Louisville, Louisville Police Department, and others. The "Oasis technique" enables police, housing authorities, other public and private agencies, and residents to analyze and solve neighborhood problems of blight and street-level crime. ILJ's final report describes in detail how the technique's eight major tasks were completed in Louisville and discusses the project's strengths and weaknesses. It also highlights factors that could affect future evaluations, and comments on the technique's potential for helping law enforcement control street-level drug dealing and related crimes in public housing.
