An Adequate Public Facilities Ordinance, APFO, or Concurrency Regulation is a legislative method to tie public infrastructure to growth for a region. APFOs take into account the availability of infrastructure. They can affect growth, but are considered separate from growth controls such as building moratoria. Ramapo, New York; Petaluma, California; and Boulder, Colorado were some of the early adopters of this tool in America. The state of Florida uses the term "concurrency" in its growth management act. * Transportation * School facilities * Water supply * Water treatment * Roads
