Commissioner District Reapportionment

Under the county’s voter-approved Charter, four of the five members of the Board of County Commissioners are elected by district. The Charter also requires a review of the population among the four commissioner districts every 10 years following the U. S. Census Bureau’s decennial count. If the population of any one commissioner district is more than 105% of than any other, new commissioner district boundary lines must be drawn. This part of the process is called “reapportionment.” At the end of the reapportionment process, the population of the newly redrawn districts must not be more than 103% of any other. This page provides information about the reapportionment process.
