  • activity and use of lavatory during sporting events
  • after-hours use and nighttime movement, both weekday and weekend, and both on-site and to/from adjacent properties
  • N/A
Safety Audits and Security Surveys
  • building floor plan
  • room/space assignments
  • class, cafeteria and sporting event schedules

  • maintenance and repair policies and procedures
  • cafeteria policies and procedures
  • hallway monitoring policies and procedures

  • building design and any related corporate policies
  • ATM location and design
  • site layout, including relationship to adjacent properties and nearby land uses
  • CCTV and lighting
  • security policies and procedures

RESPONSE: Opportunities to Control Access
  • close cafeteria and campus (no one leaves), which requires changes to lunch schedules
  • install lock on lavatory door
  • install barricade, removing access to gym/sport area(s)
  • perimeter fencing, removing access to the site
  • graffiti-resistant paint/surface treatment on problem areas
  • remove ATM completely, or move it to another location (including automobile access rather than walk-up)
  • change hours of operation and availability of ATM
  • install fence between ATM and drive-through bank lanes
Options for Providing Opportunities to See and Be Seen
  • change faculty monitoring assignments
  • install CCTV
  • change lavatory design to improve visibility
  • increase light levels
  • install CCTV
  • trim or remove vegetation
  • increase police patrol (through site as well as around site)
  • hire private security to patrol
  • increase police patrol or hire private security
  • increase lighting around the building, especially in the drive-through area
Opportunities to Define Ownership and Use, and Encourage the Maintenance of Territory
  • limit the area available for lunch outside the cafeteria
  • change lavatory available during lunch periods to one in an area that is more easily supervised
  • immediately repair and replacement of damaged fixtures, etc.
  • consistently enforce school policies and consequences for policy violations
  • negotiate alternative use strategies with neighboring property owners (e.g., “no readmittance” policy to keep skaters inside the building)
  • immediately repaint when graffiti is installed
  • N/A
ASSESSMENT: Possible Scenarios to Look For Over the Long-Term
  • there is no evidence of smoking, drinking or vandalism in the lavatory, OR
  • the problem occurs infrequently and only during sporting events when the lavatory is unlocked, OR
  • changes to lunchtime monitoring have resulted in fewer behavioral problems in other areas near the cafeteria, not just in the problem lavatory, OR
  • the problem appears in another lavatory or another location at the school, OR
  • the problem has changed, e.g., the problem is now bullying, not vandalism, OR
  • there is no evidence of tagging or graffiti on the site, OR
  • the amount and/or frequency of graffiti is reduced, OR
  • “hanging out” and other problems at the skating rink have been reduced or eliminated, OR
  • graffiti problems shift to another location on this site or elsewhere in the neighborhood, OR
  • graffiti continues to be a problem, OR
  • the problem has changed, e.g., the problem now includes vandalism to lighting, OR
  • the robbery problem is eliminated, OR
  • the adjacent commercial strip is seeing new investment and increases in patronage, OR
  • ATM patrons are now robbed at their cars, OR
  • ATM robberies move to another bank, OR
  • other types of robbery are emerging in the neighborhood
