1. CPTED
Crime 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.

7. 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.

15. 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.

16. 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.
