Why would you wait for a crime to occur if  you have the means to prevent it? One form of proactive strategy is Crime Prevention Through Environmental Design, or CPTED (pronounced sep-ted). CPTED is a philosophy that uses specific design principles to deter criminal behavior while positively impacting the image and usage of an area or facility. Instead of focusing efforts after the crime, CPTED focuses on potential criminal behavior and preventing the crime from happening in the first place.

We constantly respond to our environment, whether or not we are aware of it. Effective design of our environment helps us feel safer and reduces opportunities for criminal acts. CPTED is based on the premise that the environment directly affects our behavior. It influences both the opportunities for crime and our fear of crime. CPTED enhances safety by altering physical design and encouraging positive social interaction. CPTED offers an alternative to creating fortress-like communities where we have to lock ourselves away to feel safe and also complements police and security strategies.

How CPTED Works:

CPTED promotes design strategies in planned environments that encourage safe behavior and reduce the opportunities for crime to occur through three inter-related basic principles:

Natural Access Control (limits access)

Guides people entering and leaving a space through the placement of entrances, exits, fences, landscaping, and lighting.  Access control can decrease opportunities for criminal activity by denying criminals access to potential targets and creating a perception of risk for would-be offenders. For example, securing doors with latch guards, deadbolt locks, and keycard or code access if applicable.

Natural Surveillance (increases visibility)

The placement of physical features, activities and people in a way that maximizes visibility.  A potential criminal is less likely to attempt a crime if he or she is at risk of being observed.  Avoid landscaping that creates “blind spots” or hiding places and make sure there is effective lighting for pedestrians. For example, trimming bushes and trees so no one can conceal themselves or engage in criminal activity unseen.

Territorial Reinforcement (promotes a sense of ownership)

The use of physical attributes that express ownership such as fences, signage, landscaping, pavement designs, defined property lines and clear distinctions between private and public spaces are examples of the application of territoriality. Territoriality can be seen in entrances into a community or development, and in the use of borders and texture. For example, signage that states the name of the residential community, business, or rules that apply to that area, such as private property and/or neighborhood watch signs.

In addition to the three main principles described, two other elements support CPTED: Maintenance and Activity Support:

Maintenance (deters offenders)

A well-maintained home, building, or community creates a sense of pride. A well-kept area tends to make someone feel like they will be observed by neighbors or business owners who care about the area.  Maintenance allows for the continued use of a space for its intended purpose. It also serves as an additional expression of ownership, which helps deter criminals. If a property becomes overgrown and not cared for it encourages more crime or vandalism to occur. Without proper care, “grime leads to crime”. For example, graffiti and illegal dumping should be cleaned up within 24 hours sending a message the property is well cared for and watched. 

Activity Support (fosters community interaction)

Encouraging activities, such as community events and social gatherings, in public spaces that are intended for use by residents and other legitimate users discourages criminal acts. The objective is to increase the number of people using a space, thereby enhancing visibility, social comfort, and control. For example, host block-watch meetings and/or social gatherings to get to know your neighbors. 

If you are interested in making your home or business less appealing to criminals, then start practicing CPTED strategies today.

The concepts listed here are from Crime Prevention Through Environmental Design (CPTED) ideology. CPTED focuses on preventing crime by designing your physical environment to positively influence human behavior. These are only recommendations based on the CPTED philosophy and if implemented cannot guarantee that your home or business is impervious to crime. Through proper lighting, well maintained landscaping, proper locks, and barriers, you are creating an environment that is less desirable to criminal activity.
