This report documents the COMPASS program and its conduct and impact. COMPASS objectives include implementing a reclamation and stabilization program in selected target areas; developing computer-based mapping tools to support the reclamation activities; and evaluating the effectiveness of both the reclamation and stabilization program and the mapping tools. Program impact is summarized for each of the four different target areas: COMPASS had a significant impact in Charter Oak Terrace in terms of reducing drug activity and improving the quality of life; a minority of residents in Milner felt fewer people were selling drugs and that there was less violent crime; reclamation had a moderate impact in Frog Hollow; crime statistics for Asylum Hill suggest that reclamation had a moderate impact on levels of crime, but surveys of neighborhood residents indicate a significant impact. The COMPASS experience suggests that the neighborhood- oriented anti-drug approach may prove effective if a viable neighborhood exists. 15 references, 54 exhibits, and 2 appendixes
