THE SOUTHWARK PLAZA, PHILADELPHIA, RESIDENTIAL PROJECT WAS FORCED TO REJECT ITS APPROACH OF PROVIDING AGE INTEGRATED HIGH-RISE HOUSING. OLDER RESIDENTS TENDED TO BE VICTIMIZED BY YOUNGER RESIDENTS UNTIL A BUILDING WAS DEDICATED TO THE ELDERLY AND ARCHITECTURAL DESIGN CHANGES WERE IMPLEMENTED. IN FLORIDA, ARCHITECTURE WAS USED TO DEFINE NEIGHBORHOODS, A TERRITORIALITY APPROACH THAT FOSTERED COMMUNITY ACCEPTANCE OF RESPONSIBILITY FOR CRIME PREVENTION. THE THIRD PROJECT IS THE COMMUNITY SECURITY ORGANIZER PROJECT IN PITTSBURGH (PA). PARTICIPANTS ARE HOUSING PROJECT RESIDENTS WHO HELP MAINTAIN CLOSE CONTACT WITH RESIDENTS AND POLICE.
