The Department of Planning and Zoning is responsible for Current Planning, Long Term Planning, Zoning Compliance, and related administrative duties. These functions help to ensure and facilitate high quality and orderly development, the protection of property values, and the protection of the public health and general welfare of the community.

The Comprehensive Plan, the Official Zone Map, the Plainfield Zoning Ordinance, and the Plainfield Subdivision Control Ordinance, along with Petitions, and administrative functions are the tools used to implement these goals.

The staff reports to the Plainfield Plan Commission (PC), the Plainfield Board of Zoning Appeals (BZA), the Plainfield Design Review Committee (DRC), and the Town Council. The Planning and Zoning staff also works closely with the Town Manager, the Town Engineer, and the Town Building Inspector, and other staff in review of these matters.
