Crime Prevention Through Environmental Design (CPTED) Practice Exam

What is referred to as the 2 foot 6 foot rule in landscaping?

1. Low ground vegetation shorter than 2 feet

2. Building height limitations

3. Tall trees over 6 feet

4. Both of the above

The correct answer is: Low ground vegetation shorter than 2 feet

The 2 foot 6 foot rule in landscaping is a guideline related to the management of vegetation to enhance safety and visibility in the environment. Specifically, it refers to maintaining low ground vegetation that is no taller than 2 feet within a certain distance from structures and pathways, while ensuring that any taller vegetation, such as trees, should be pruned or maintained to a height of no less than 6 feet. This practice serves to improve sightlines and reduce concealment opportunities for potential offenders, thereby increasing the safety and security of an area. By keeping ground vegetation low, it allows for better visibility and sight lines, which are crucial in crime prevention. When people can see clearly into an area, it creates a sense of openness and reduces the likelihood of concealed activities that could lead to criminal behavior. The other options relate to building height and the height of trees, but they do not encapsulate the specific intent and application of the 2 foot 6 foot rule as it pertains to improving visibility and minimizing hiding places through careful landscaping choices.
