In 1995 the GMA was amended to require counties and cities to include the best available science in developing policies and development regulations to protect the functions and values of critical areas.  All counties and cities in the state are required to review, evaluate, and, if necessary, revise their critical areas ordinances according to a schedule established by the state Legislature and approved by the Governor in 2002. Local governments can use information from the list below in developing their GMA Update.
