Mission Statement: The Clark County Planning and Zoning Department continually strives to provide quality service and products regarding land information, land use, survey, rural addressing, and ordinance administration.

The Clark County Planning and Zoning and Land Information Department handle a variety of land use and development issues. This department protects Clark County's natural resources through the administration and enforcement of land management ordinances. This department issues sanitary permits, land use permits, and nonmetallic mine reclamation permits.  Land use permits are issued, when required, for development in shoreland or wetland zoned areas, forest and recreation zoned areas, and mapped floodplain areas.

This department’s Surveying Division remonuments section corners and surveys county-owned lands. Clark County has increased remonumentation efforts in the last few years to reestablish and maintain many neglected section corners.

Land information is managed and updated utilizing Geographic Information System (GIS) software. Many of the digital land information data layers are compiled and created by this department. This information is available through a free GIS site that provides a minimum of data layers or a fee-based site that includes additional data layers and also provides access to other county department records.

The Clark County Planning and Zoning Department has assisted local municipalities in developing comprehensive plans.  The adopted plans, supplemental planning documents, and additional reference maps and documents are also available online for public use.
