A plat is a map of a subdivision that represents a tract of land, showing the boundaries and location of individual properties, streets, easements, and other pertinent information.
Plat applications are submitted to and processed by the Planning Department and considered for action by the Plan Commission. After a plat is approved by the Plan Commission, it is filed with Dallas County and becomes a legal lot of record for which a site or building permit can be issued.
The Plat Application can be found here: Plat Application.
