The Urban Crime Prevention Program (UCPP) was designed to combat urban crime through the establishment of 85 innovative neighborhood-based crime prevention projects across nine cities for 18 months. UCPP's main goals were to increase citizen participation in innovative neighborhood crime prevention efforts, to bolster the capabilities of neighborhood groups, and to forge working partnerships between these groups and related agencies and institutions. A two-year evaluation, summarized here, concluded that the most effective crime prevention approaches, as measured by UCPP goals, involved property crime and arson prevention projects, primarily because they were based on the organization of citizens through neighborhood groups. Many UCPP projects had difficulty with more complex approaches, particularly if the project was located in a deteriorated neighborhood. In an overall sense, however, it was concluded that the general neighborhood orientation of UCPP, combined with the establishment of working partnerships with other agencies, offers promise for combatting urban crime. It is recommended that (1) community crime prevention programs emphasize the organization of citizens as the basic strategy; (2) strong working partnerships be established between neighborhood efforts and relevant criminal justice agencies; (3) involved neighborhood groups receive substantial training and technical assistance; and (4) neighborhood based crime prevention strategies receive the continued support and attention of officials concerned with urban crime.
