The Codes Study Is Updated
"The Codes Study is a collaborative effort led by Hazel Borys, Emily Talen, and Matthew Lambert, and contributed to by many public and private planners, tracking the prevalence of form-based codes worldwide. As of March 2016, we’ve tracked 618 codes that meet criteria established by the Form-Based Codes Institute (FBCI), as well as an additional 16 form-based guidelines. 362 of these are adopted, with others in progress. Even though form-based codes are 35 years old, 87% have been adopted since 2003."
"Big city adopters include Miami, Nashville, Dallas, Ft. Worth, Denver, Albuquerque, El Paso, Memphis, Baltimore, Tulsa, Portland, Cincinnati, Philadelphia, Los Angeles, San Diego, Austin, Chattanooga, Atlanta, Jacksonville, Calgary, Abu Dhabi, Dammam. And because the unit of urban design is the neighborhood, form-based codes have also been applied to as small as 100-person populations and 35 acres."
