Design Strategies

There are three overlapping CPTED design strategies.

  • Natural access control is a design strategy that is directed at decreasing crime opportunity. The primary thrust of an access control strategy is to deny access to a crime target and to create a perception of risk in offenders. This is best accomplished by directing normal access to observable areas and preventing access to unobservable areas. Glazing and proper placement, selection, and maintenance of plant materials should be considered to maximize natural surveillance opportunities.
  • Natural surveillance is a design strategy that is directed at keeping intruders under observation. Designing for natural surveillance involves providing ample opportunity for legitimate users, engaged in their normal activities to observe the space around them .
  • Territorial reinforcement is an "umbrella" design strategy that realizes that physical design can create or extend a sphere of influence so that users of a property develop a sense of proprietorship over it and potential offenders perceive that territorial influence.
    "Territoriality" is a concept intended to clearly delineate a space as public, semi- private, or private space and to create appropriate ownership of that space. It will often embody natural surveillance and natural access control strategies.
