Crime Prevention through Environmental Design (CPTED)
Crime Prevention through Environmental Design (CPTED) What is
CPTED? The official book definition is "the proper design and
effective use of the built environment that can lead to a
reduction in the fear and incidence of crime and an improvement
in the quality of life." It is simply a goal to reduce
opportunities for crime that may be inherent in the design of
structures or in the design of neighborhoods. In other words,
make your home or neighborhood unappealing to burglars and
thugs. Cities and Counties throughout the country are adopting
CPTED ordinances requiring site plan reviews with crime
prevention in mind. Law enforcement officers who are specially
trained in CPTED are now working closely with Planners,
Architects, City Officials, and Educators to ensure the proper
design of structures, schools, and neighborhoods. These experts
know how the design and use of the environment can control human
or criminal behavior and reduce the fear of crime. They used
natural means such as landscaping to deter criminals. Access
control, natural surveillance, different aspects of lighting and
its effects on human behavior, all deter crime. Many landscape
specialists incorporate CPTED into their layout & design of
landscapes. Each of the following CPTED strategies are low cost
guidelines that they apply to reduce the fear and incidence of
crime and improve the quality of life. 1. Natural Access
Control guides people entering & leaving a space through the
placement of entrances, exits, fences, landscaping & lighting.
Access control can decrease opportunities for criminal activity
by denying criminals access to potential targets & creating a
perception of risk for would-be offenders. Walkways &
landscaping should direct visitors to the proper entrance & away
from private areas. The design should create a perception of
risk for would-be offenders. Walkways should be installed in
locations safe for pedestrians & keep them unobscured. 2.
Natural Surveillance is the placement of physical features,
activities & 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. At the same time, we are
likely to feel safer when we can see & be seen. The landscaping
should be selected and installed to allow unobstructed views of
doors & windows. The front door should be at least partially
visible from the street. Shrubs & bushes near windows should not
restrict full visibility of the property. Sidewalks & all areas
of the yard should be well lit. 3. Territorial Reinforcement is
use of physical attributes that express ownership such as
fences, signage, landscaping, lighting, pavement designs, etc.
Defined property lines and clear distinctions between private &
public spaces are examples of the application of territoriality.
Front porches or stoops should create a transitional area
between the street & the home. Property lines & private areas
should be defined with plantings, fences or retaining walls. Use
thorny plants along fence lines and under windows to deter
access by intruders. 4. Maintenance is a well maintained home,
building or community, and creates a sense of ownership. A well
kept area tends to make someone feel like they will be observed
by neighbors or business owners as it is obvious people care
about the area. Keep trees & shrubs trimmed back from windows,
doors & walkways. Keep shrubs trimmed to 3 feet & prune the
lower branches of trees up to 7 feet. Use exterior lighting at
night & keep it in working order. Keep litter & trash picked up
& the yard neat & free of items that might attract theft. You
