Model codes that are procedural rather than form-based can help create good urbanism if they are intelligently adapted to a specific locality. They do not regulate form in the sense of an urban or form-based code, but they do affect form indirectly by specifying a decision making process. During that process, local plans, regulations and policies are applied to a development, and that is likely to affect the development's character - i.e., urban form. Often, these procedures are applied to all developments that require a quasi-judicial decision, for example, planned unit developments and site plans. There is disagreement over whether model procedural codes result in desirable urban forms.
