The creation of a plat map marks an important step in the process of [[incorporation (municipal government)|incorporating]] a [[town]] or [[city]] according to [[United States]] law. Because the process of incorporation sometimes occurred at a [[courthouse]], the incorporation papers for many American cities may be stored hundreds of miles away in another [[States of the United States|state]].  For example, to view the original [[United States General Land Office]] plat for the city of [[San Francisco, California]], filed in 1849, one must visit the Museum of the Oregon Territory in [[Oregon City, Oregon]], as at that time Oregon City was the site of the closest federal land office to San Francisco.<ref name="Clackamas">{{Cite news |date=1904-03-13 |title=First Plat of San Francisco Found |url=https://clackamascountyhistoricalsociety.wordpress.com/2012/03/13/first-plat-of-san-francisco-found/ |access-date=February 11, 2017 |work=The Oregon City Enterprise |via=Clackamas County Historical Society}}</ref>
