The Development Review office provides efficient and effective review, evaluation and monitoring of all development project activities within the unincorporated areas of Marion County. The office receives, routes, and monitors all development project submittals. This includes coordinating review of all master plans, preliminary plats, improvement plans, final plats, major site plans and waiver requests for compliance with the Marion County Land Development Code.

During the review process, Development Review serves as a central hub for compilation of all County review comments. Projects with completed reviews are scheduled once a week as agenda items for the Development Review Committee (DRC). The DRC consists of five voting members including the county engineer, planning director, utilities director, zoning and planning manager and the fire marshal. who will make a motion for approval or disapproval of agenda items. Disapproval of any agenda item by the DRC may be appealed to the Board of County Commissioners, whose decision shall be final.
