A plat is a map of a tract of land subdivided into lots with streets and alleys drawn to scale showing dimensions. Usually an owner of a tract of land chooses to plat the land so lots can be sold. Instead of a metes and bounds description, a lot, block and name of a plat are used to describe the property. For more information about subdividing land, contact the city planner of the city where the land is located. Contact the Clay County Planning and Zoning Department by telephone at 218-299-5005 or by emailing Planning, if the land is outside of city limits but within Clay County. See Minnesota Statute 505 Plats; Coordinates; Surveys online for more information.

Addition vs. Subdivision

In most cases, in Clay County, the word addition is used when subdividing land within city limits. The word subdivision is used when subdividing land outside of city limits.

When a survey or plat is made, proper recording of Corner Certificates is required, consisting of a minimum of two or more appropriate controlling government corner locations.
