CPTED Design Guidelines
As a general CPTED guideline, when considering fencing for a project, utilize an "open" decorative design as opposed to solid fencing.
CPTED Design at Home
One of the most vulnerable places at your home is the narrow side yard. Good CPTED design guidelines recommend  that you don't let the landscape become overgrown, creating a hiding place for criminals. Use low-growing shrubs and a gravel path for Natural Access Control or an open fencing design. This is good CPTED practices.

Our CPTED security consultants have decades of experience in crime prevention with extensive training and experience in the theory of Crime Prevention Through Environmental Design or CPTED. There are four important CPTED design guidelines which you should follow when conducting a CPTED security property assessment. Following are a brief overview of the four main CPTED design guidelines widely accepted by CPTED practitioners.

CPTED Lighting

CPTED Principle #1
Natural Surveillance

"See and be seen" is the overall goal when it comes to CPTED and natural surveillance. A person is less likely to commit a crime if they think someone will see them do it. Lighting and landscape play an important role in Crime Prevention Through Environmental Design.

CPTED Principle #2
Natural Access Control

Natural Access Control is more than a high block wall topped with barbed wire. Crime Prevention Through Environmental Design or CPTED utilizes the use of walkways, fences, lighting, signage and landscape to clearly guide people and vehicles to and from the proper entrances. The goal with this CPTED principle is not necessarily to keep intruders out, but to direct the flow of people while decreasing the opportunity for crime.

CPTED Principle #3
Territorial Reinforcement

Creating or extending a "sphere of influence" by utilizing physical designs such as pavement treatments, landscaping and signage that enable users of an area to develop a sense of proprietorship over it is the goal of this CPTED principle. Public areas are clearly distinguished from private ones. Potential trespassers perceive this control and are thereby discouraged.

CPTED Maintenance and Broken Windows

CPTED Principle #4

CPTED and the "Broken Window Theory" suggests that one "broken window" or nuisance, if allowed to exist, will lead to others and ultimately to the decline of an entire neighborhood. Neglected and poorly maintained properties are breeding grounds for criminal activity. We will work with you to develop a formal CPTED based maintenance plan to help you preserve your property value and make it a safer place.
