Summit County was created from townships in two original subdivisions, the Connecticut Western Reserve, covering most of the county, and the Congress Lands, covering Green and Franklin Townships. The Western Reserve east of the Cuyahoga and the Old Portage Path (the western boundary of the United States at that time) was surveyed in 1796-97. The portion west of the of this line was not surveyed until after 1805. The Congress Lands were surveyed 1801-1803.
