Design Guidelines

The design guidelines (PDF) have been created to assist in achieving a high quality of aesthetic and functional design throughout Diamond Bar. The guidelines are to be applied in conjunction with development standards in implementing the City’s development review process and are intended to protect and enhance the city’s unique character and assets and to ensure the stability and growth of public and private investment in land and improvements. The purpose of these guidelines is to promote development which respects the physical and environmental characteristics of the community and the site, and which reflects functional and attractive site planning and high quality design.
