In 1978, Maine -- a rural, sparsely populated, comparatively poor State -- faced many problems with its jails including antiquated facilities and overcrowding. The Maine Criminal Justice Planning and Assistance Agency and the Maine Sheriffs' Association (MSA) funded a statewide detention study which defined goals and objectives and has served as a model for local efforts. A common feature of the new jail designs is their diversity, which reflects the clear articulation of local goals, objectives, and policies. Most recent jail improvements in Maine have involved renovation and expansion of existing facilities rather than new construction. A case study of Piscataquis County illustrates planners' aggressive strategy to obtain public support for jail renovation bond issues. The report highlights the Maine Department of Corrections' efforts to revise its jail standards and develop improved inspection procedures. Accomplishments of the MSA are highlighted, as are corrections improvement projects undertaken by Maine counties. Tables, drawings, and photographs.
