Crime Prevention Through Environmental Design


Crime Prevention Through Environmental Design, commonly referred to as CPTED, is based on the theory that proper design can lead to a reduction in fear of crime and thus a reduction of crime itself.  The two basic goals of CPTED are to discourage inappropriate behavior while promoting positive interactions.

Key principles of CTPED include:

Natural Surveillance – arranging signing, landscaping, and other features to maximize visibility.  Proper lighting of entrances and exits is a good example of maximizing visibility at night.

Access Management – controlling people coming and going from a space.  Lock on doors or gates can provide access control.

Territoriality – defining your personal space and showing pride and ownership. 

Physical Maintenance – the general upkeep and repair of the environment.  Spaces that are well maintained show ownership and safety.

Activity Support – the placement of activities that promote natural surveillance, access management, and territoriality.   

CPTED reviews are done by the staff of the Boise Police Crime Prevention Unit and include reviewing site plans and existing buildings.
