This chapter looks at design guidance produced by government, police and local government sources. ‘‘Secured by Design’’ is a Police initiative that was launched in 1989. The Dutch Police Labelling developed out of this. Local authorities have traditionally produced planning design guides that contain information on designing crime out of the built environment. Essex County Council was one of the first to do so. Nottingham City Council and others have produced guides specifically related to crime prevention. The City of Toronto in Canada has a long-standing international reputation for its effective policies in the area of crime prevention through environmental design. The European Parliament Prestandard ‘‘Prevention of Crime by Urban Planning and Design’’ reflects its concern that people within the European Union should enjoy living in a crime-free environment. This chapter draws out the key principles from these publications to provide a compendium of design criteria.
