A multidisciplinary approach to deterring crime through the design of the built environment — reducing crime and fear through strategic use of space, light, landscaping, and access.
01
Natural surveillance
Maximize visibility with clear sight lines, proper lighting, and maintained vegetation.
02
Natural access control
Guide movement and limit opportunity through design, barriers, and defined entries.
03
Territorial reinforcement
Establish clear ownership with markers, signage, and physical delineation of space.
Maintenance underpins all three. It isn't a separate principle — sustained upkeep is the critical factor that keeps surveillance, access control, and territorial reinforcement effective over time.
