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.
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.
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.
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.
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.
