§ 90. Purposes of article. The purposes of the provisions of this
article are:

1. To provide correctional programs for persons who receive sentences
of imprisonment with terms of one year or less and who otherwise would
be confined in institutions in counties that do not have a sufficient
number of incarcerated individuals to justify construction of an
adequate correctional institution or operation of a modern correctional
program;

2. To provide a method of relieving space pressures in correctional
institutions operated by local government; and

3. To expand the use of programs designed to bridge the gap between
incarceration and activities in the community, through the use of
institutions operated by local government as facilities for residential
treatment of persons in the custody of the state department of
corrections and community supervision.
