Crime Prevention Through Environmental Design

Crime Prevention Through Environmental Design (CPTED)

CPTED (pronounced SEP-TED) is a proactive design philosophy that is built around a core set of principles based on the belief that proper design and effective use of the built environment can lead to a reduction in the fear and incidence of crime as well as an improvement in the quality of life.

CPTED is a component of the City's Business Watch program, a free, voluntary program that involves businesses taking systematic steps to reduce opportunities for crimes in and around business locations. In conjunction with the RCMP, the City of Kamloops has trained staff and Crime Prevention volunteers that can conduct a safety analysis of your business and provide recommendations on improvements and/or training to reduce the likelihood of your business being victimized by crime.

CPTED Principles

The four principles of CPTED are natural access control, natural surveillance, territorality, maintenance and management.

    Natural Access Control

    Natural access control is a design concept that is directed at decreasing the opportunity for crime based on the premise that an individual confronted with a clearly defined boundary will likely show deference, and respect the way it guides and influences their movement as they transition from public to private space.

    Practical application includes the following:

    • control how people enter and exit the space
    • remove potential targets
    • creates a higher perception of risk for the potential offender
    • criminals weigh the risk versus return
    Natural Surveillance

    Natural surveillance is the establishment of clear sightlines that allow for visibility which reduces the likelihood of crime occurring.

    Practical application includes the following:

    • see who enters and exits the space
    • improve visibility through windows
    • use proper lighting
    • integrate mixed-use spaces to aid in 24-hour surveillance

    Territoriality implies that a space’s physical design can create or extend a sphere of influence so users develop a sense of ownership that is noticeable and will challenge behaviour.

    Practical application includes the following:

    • create defensible space
    • create a sense of private ownership
    • personalise the space through artistic design, furniture, colour
    • use cues that indicate the separation of public versus private space
    Maintenance and Management

    Maintenance and management is the expression of ownership of property that demonstrates a sense of pride and caring about the community.

    Practical application includes the following:

    • provide cues to the public to indicate the space is watched
    • demonstrate pride in the space
    • demonstrate the intolerance of undesirable behaviour in the space
