The Total Land Area may differ from platted or deeded area. For example: a platted subdivision lot may be platted as 50 feet by 100 feet for a total land area of 5,000 square feet. Whereas, the OCPA’s Total Land Area may display a size such as 5,011 square feet - being slight more or less due to the positional accuracy of GIS cadastral map construction and numerical rounding. OCPA recommends a manual calculation of the land area based on the platted or deeded dimensions (as displayed on the GIS map). The Total Land Area may also differ from information shown in the Land Information section of the OCPA web site. The Total Land Area includes both upland and any submerged areas lying within the parcel boundary.
