The Design Guidelines serve as companion documents to the Fairfax County Comprehensive Plan. The Comprehensive Plan describes desired land uses and levels of intensity of development and provides general guidance on built form and open space. The Design Guidelines provide detailed guidance regarding the desired character of the built environment, including site design, building massing, and the treatment of interim conditions; are used to inform the design of components of the public realm such as streetscapes, plazas, parks, and landscaped areas; and are a complement to the Comprehensive Plan for use by citizens, developers, landowners, designers, Fairfax County staff, the Fairfax County Planning Commission, and the Board of Supervisors when either planning, designing, proposing, or reviewing development proposals.
