When it was founded, JPL's site was immediately west of a rocky flood-plain – the [[Arroyo Seco (Los Angeles County)|Arroyo Seco]] riverbed – above the Devil's Gate dam in the northwestern [[Salient (geography)|panhandle]] of the city of Pasadena in [[Southern California]], near [[Los Angeles]]. While the first few buildings were constructed in land bought from the city of Pasadena,<ref name="Henry"/> subsequent buildings were constructed in neighboring unincorporated land that later became part of [[La Cañada Flintridge]]. Nowadays, most of the {{convert|168|acre|ha|0}} of the [[Federal government of the United States|U.S. federal government]]-owned NASA property that makes up the JPL campus is located in La Cañada Flintridge.<ref>{{cite web |url=https://unitelcf.files.wordpress.com/2014/09/la-canada-flintridge_lafco-map-spere-of-influence.pdf |title=Local Agency Formation Commission for the County of Los Angeles |access-date=2016-02-17 |archive-date=2017-03-05 |archive-url=https://web.archive.org/web/20170305012949/https://unitelcf.files.wordpress.com/2014/09/la-canada-flintridge_lafco-map-spere-of-influence.pdf |url-status=live }}</ref><ref name=latimes>{{cite web |url=http://latimesblogs.latimes.com/readers/2012/08/jpl-mars-curiosity-la-canada-flintridge.html |title=Location of NASA's JPL is a bit of a curiosity |date=9 August 2012 |access-date=28 April 2017 |archive-date=2 August 2017 |archive-url=https://web.archive.org/web/20170802044249/http://latimesblogs.latimes.com/readers/2012/08/jpl-mars-curiosity-la-canada-flintridge.html |url-status=live }}</ref> Despite this, JPL still uses a Pasadena address (4800 Oak Grove Drive, Pasadena, CA 91109) as its official mailing address.<ref>{{cite web |title=Directions and Maps |publisher=Jet Propulsion Laboratory |access-date=29 April 2017 |url=https://www.jpl.nasa.gov/about_JPL/maps.php |archive-date=17 March 2020 |archive-url=https://web.archive.org/web/20200317234905/https://www.jpl.nasa.gov/about_JPL/maps.php |url-status=live }}</ref> There has been occasional rivalry between the two cities over the issue of which one should be mentioned in the media as the home of the laboratory.<ref name=latimes/><ref>"Pasadena to ask JPL land annexation", Pasadena Star News 11, March 1976;</ref><ref>"JPL Faces an identity crisis following incorporation vote", Pasadena Star News, 15 Nov 1976</ref><ref>"The great battle for JPL", La Canada Valley Sun 18 Mar. 1976</ref>
