The board shall designate not fewer than nine regions in the state for the purpose of providing regional state jail felony facilities. The board shall ensure that regions are designed to efficiently serve community supervision and corrections departments. The board may not designate a region that contains a part of an area served by a community supervision and corrections department. The board may designate a region that contains only one judicial district, but only if the judicial district serves a municipality with a population of 400,000 or more. Any other provision of law that would otherwise require the board to designate regions on the basis of uniform service regions does not apply to this section.
