Located in the state of Missouri and is within the counties of Jackson and Cass, whose area is primarily within Jackson. At the start of 2010, the city’s population started to rise and making the city the state’s largest city and also in the Kansas City metropolitan area where it is also a part of. During the years after it was founded, the surveyors for the Missouri Pacific Railroad came to the area, the local settlers and the railroad wanted to name the area in honor of Dr. Lea, the listed postmaster in Big Cedar in 1855, who was killed by the Kansas Jaywalkers or the Redlegs, whose murder site took place near the site of the proposed depot for the railroad. Afterwhich, they chose the name “Lea’s Summit” to reflect its relatively highest elevation between the Missouri Pacific Railroad and of the St. Louis and Kansas City. And because of the misspelling, they spelled it as “Lee’s Summit” on a boxcar that is serving as a station and was donated b the Missouri Pacific, and then a sign to the tracks, and finally in the printed schedule for the railroad. It has then remained to be Lee’s Summit ever since.
