CPTED Presentation Presentation Transcript

  • 1. CPTEDCrime Prevention through Environmental Design Jesse DeBauche & Chuck Vanhorn
  • 2. Concepts of CPTED To make crime less appealing/reduce opportunities via environment landscaping and design.Examples: Bushes, shrubs to prevent pedestrian access. Trees providing privacy cover near windows. Fences to restrict access. Lighting to reduce dimly lit areas.
  • 3. Entrances Well lit, doors that allow optimal visibility in and out, in constant sight of personnel. Bright lights create a feeling of security and visibility. Well-cared for plants send the message that the property is maintained, which might suggest any disturbances to such areas would be noticed.
  • 4. Property Well maintained, again gives the impression the property is cared for, thus any disturbances will be noticed. Fencing restricts access to areas that people should not be in, privacy fencing allows restricted sight however that can work inversely for the criminal(s). Chain link fences restrict/direct flow of traffic while providing visibility. Poles restrict vehicle access.
  • 5. Broken Window Theory The theory that if a neighborhood is not taken care of (ie. Broken windows, uncut lawns, trash in streeths, etc.) then crime is less likely to be reported/more likely to occur in that neighborhood. Inverse theory to CPTED. − If a neighborhood/business is well maintained, crime is more likely to be reported, less likely to occur, more likely to be noticed and more likely to be averted. In theory.
  • 6. Security Through Design Many CPTED practices inherently bring the sense of security (fenced yards, well lit areas) to legitimate patrons. They also reduce the feeling of comfort or security for criminals, making attempts seem riskier and potentially less desirable. Windows without obstructions allow visibility in and out, allowing for witnesses and for seeing people come and go.
