CPTED places the greatest emphasis on which crime prevention strategy?
Natural crime prevention strategies
Is landscaping an important element when applying CPTED concepts?
Yes.
- 2ft to 6ft rule allows natural surveillance.
- it helps with wayfinding/ pathfinding
- displays teritorial reinforcement
Is a maintenance plan essential in landscaping?
Yes. Its displays ownership, and territorial reinforcemt and allows natural surveiland if 2ft/ 6ft rule is applied in landscaping
From a CPTED standpoint, landscaping should not disrupt critical areas of natural surveillance. What are examples where natural surveillance is critical?
If landscaping kept to 2ft/ 6ft rule in parking lots, pedestrian paths, and commin areas, it allows:
- direct observation of these areas (at least 30ft) to deter crime due to natural surveillance
- it can act as natural barriers for transition zones from public, to semi-public, to private areas
- it can assist with pathfinding
- it shows ownership through territorial reinforcement
In landscaping, what is the 2ft to 6ft rule?
- Not allowing bushes/ shrubs to grow past 2 feet
- not allowing tree canopies to grow below 6ft
Both which allow for natural surveilance and territorial reinforcement
