In this chapter we move beyond the more theoretical discussions and begin the heavy work of explaining how to actually integrate crime prevention into the planning process. Specifically, we will discuss different models that have been employed, barriers to effective integration, tools for considering crime in planning, and practical guidance on key issues in planning and crime. The incorporation of crime prevention principles into urban planning is a relatively new phenomenon compared to the many more traditional crime prevention programs. Nevertheless, there are a host of examples of how it has been attempted, what has worked, and how to improve on prior practices.
