This document provides guidelines to organizations for establishing the basic elements, strategies and processes for preventing and reducing crime and the fear of crime at a new or existing built environment. It recommends the establishment of countermeasures and actions to treat crime and security risks in an effective and efficient manner by leveraging environmental design. Within this document, the term "security" is used in a broad manner to include all crime, safety and security-specific applications, so it is applicable to public and private organizations, regardless of type, size or nature. While this document provides general examples of implementation strategies and best practices, it is not intended to provide an exhaustive listing of detailed design, architectural or physical security crime prevention through environmental design (CPTED) implementation strategies or restrict the potential applications to only those examples provided in this document.
