Johnson County (county code JO) is a county located in northeast Kansas, in the central United States. The county is largely suburban, being part of the Kansas City metropolitan area, and containing many of its affluent southwestern suburbs. As of the 2010 census, the county population was 544,179.[1] Its county seat is Olathe,[2] and its most populous city is Overland Park. The county has the highest median household income and highest per-capita income in Kansas and is among the most affluent in the United States, boasting the 19th highest median household income in 2000 [3] and the 46th highest per-capita income in 2005.[3]

In 2010, Money magazine, in its list of the 100 Best Cities in the United States in which to live, ranked Overland Park 7th (ranked 6th in 2006 and 9th in 2008) and Shawnee 17th (ranked 39th in 2008).[4] In 2008 the same magazine also ranked Olathe 11th.[5]

History Edit

Johnson County is named for Thomas Johnson, and was one of the first counties established in the Kansas Territory in 1855. The Oregon-California and Santa Fe Trails, pass through nearby Independence, Missouri, also passed through the county. The renowned gunfighter Wild Bill Hickok settled for a time in the county, becoming constable of Monticello Township in 1858. Johnson County was the site of many battles between Abolitionists and pro-slavery advocates during Bleeding Kansas. In 1862 Confederate Guerrillas from nearby Missouri led by William Quantrill raided the Johnson County communities of Olathe and Spring Hill, killing half a dozen men and destroying numerous homes and businesses.

The county was largely rural until the early 20th century, when housing subdivisions were developed in the northeastern portion of the county adjacent to Kansas City, Missouri. Developer J.C. Nichols spurred the boom in 1914 when he built the Mission Hills Country Club to lure upscale residents who previously had been reluctant to move from Missouri to Kansas.[6] Suburban development continued at a steady pace until the close of World War II. Following the war, the pace of development exploded, triggered by the return of soldiers in need of housing and white flight, a common occurrence throughout the United States during the post-war period. The US Supreme Court 1954 school desegration ruling and its impact in Kansas City, Missouri contributed to white flight throughout the region, resulting in increased migration from Kansas City, Missouri to the county and the furthering the county's reputation as a destination for quality public schools and as a good location for families. This growth slowed slightly in the 1970s, however beginning in the mid 1980's the pace of growth increased significantly, with the county adding 100,000 residents each decade between the 1990 census and 2010 census.

Law and government Edit

Laws Edit

Johnson County was a prohibition, or "dry", county until the Kansas Constitution was amended in 1986 and voters approved the sale of alcoholic liquor by the individual drink with a 30% food sales requirement.[7]

Federal representation Edit

Johnson County is a part of Kansas's 3rd congressional district, which elected Republican Kevin Yoder in the 2010 midterm elections. The two U.S. Senators from Kansas are Republican Senators Pat Roberts and Jerry Moran. The most affluent county in Kansas, Johnson County is solidly Republican. President George W. Bush received 61% of the vote in 2004. Johnson County has not supported a Democrat on the Presidential ticket since Woodrow Wilson in the 1916 election.[8][9]

State representation Edit

Johnson County is home to 22 Kansas state representatives and 7 Kansas state senators. 21 out of 22 of Johnson County's representatives are Republicans, as are all 7 of the county's senators.[10][11] Most Johnson County Republicans identify themselves as moderates, the more socially progressive and fiscally conservative faction of the Kansas Republican Party. Johnson County House and Senate members at times come into conflict with representatives from other areas of the state, most notably in 2004 in the debate over school finance.[12]

County Government & Unincorporated Areas Edit

The county government is administered by an elected, seven-member Board of County Commissioners.[13] Ed Eilert, former mayor of Overland Park serves as the current County Chairman. Governance of the county is divided into six districts. The county government has full jurisdiction of the unincorporated areas of the county and limited jurisdiction of those areas of the county within incorporated places. For instance, decisions regarding the regulation of land use, development and zoning in unincorporated areas of the county are the responsibility of the county government, whereas such decisions for areas within incorporated places are the jurisdiction of the incorporated city of which the property is a part.

The current sales tax rate in Johnson County is 6.4%, slightly higher than the 6.3% rate in Wyandotte (where Kansas City, Kansas is located).[14] The sales tax rates of each of the surrounding counties are nearly the same as the rate in Johnson County.[14] Individual cities also have additional sales taxes that are added on to these figures.

Property taxesEdit

Property taxes are a conglomeration of state, county, city, and school district taxes. Property tax rates are generally lower in Johnson County because property values in the county are higher than in other counties throughout Kansas.

Topography Edit

The natural topography of the county consists of gently rolling terrain. The Kansas River forms a portion of the northwest boundary of the county. The elevation generally increases from north to south as the distance from the Kansas River and Missouri River increases.

Watersheds & Streams Edit

The county is drained by the watersheds of the Kansas River, Blue River and Marais des Cygnes River all of which are part of the Missouri River watershed.[16] Being located in northeastern Kansas, the county receives plentiful rainfall. Consequently, the county contains numerous small streams, including Kill Creek, Mill Creek, Turkey Creek, Indian Creek, Brush Creek, Tomahawk Creek, the Blue River, Bull Creek and Little Bull Creek.

Kill Creek begins in the southwest portion of the county and flows northward into the Kansas River at DeSoto. Mill Creek begins in the central portion of the county in Olathe, flowing northward it empties into the Kansas River at Shawnee. Turkey Creek and Brush Creek each begin in northeast Johnson County. Turkey Creek flows northeastward into Wyandotte County and joins the Kansas River just before its confluence with the Missouri River at Kaw Point. Brush Creek flows east-northeastward through Prairie Village and Mission Hills, entering Kansas City, Missouri within the median of Ward Parkway and passing the Country Club Plaza before emptying into the Blue River east of the Country Club Plaza and north of Swope Park. Indian Creek begins in the southern portion of Olathe and Tomahawk Creek begins in south Overland Park. Each flows northeastward meeting in Leawood, where the stream retains the name of Indian Creek, just before crossing the state line and entering the Blue River in Kansas City, Missouri. The Blue River begins in rural southern Johnson County and flows north-northeastward through the southeastern portion of the county and crossing the state line just east of the intersection of 151st Street and Kenneth Road in southern Overland Park. The Blue River flows through southern and eastern Kansas City before joining the Missouri River. Bull Creek and Little Bull Creek begin in rural southwestern Johnson County and flow southward where they enter Hillsdale Lake before continuing into Miami County, eventually joining the Marais des Cygnes at Paola.

Flora & Fauna Edit

The county consists primarily of prairie grassland with corridors of forested areas along streams and rivers.

Land & Water Area Edit

According to the 2000 census, the county has a total area of 480.15 square miles (1,243.6 km2), of which 476.78 square miles (1,234.9 km2) (or 99.30%) is land and 3.37 square miles (8.7 km2) (or 0.70%) is water.[17]

Transportation and infrastructureEdit

Johnson County has a grid network through most of the county with a road every mile. The grid has facilitated rapid growth and easy access. Interstate 435 runs through much of the county, and serves as a developmental "border" in the along the northbound/southbound portion. The westbound/eastbound part of I-435 divides the county into a northern and southern section. The northern section is older, while the southern portion is the fastest-growing area in Johnson County, as well as containing a massive volume of new homes.

The Johnson County street grid begins at around Johnson Drive (near 55th street), and is a continuation of the adjacent Kansas City, Missouri street grid. The grid continues to about 175th street, with most suburban development ending around 159th street.

Other highways running through the area are Interstate 35, which runs diagonally through the county, starting from Downtown Kansas City, Missouri and continuing through Olathe, KS, Gardner, KS and eventually leads to the US-Mexico border, US Highway 69, which changes from Interstate 635 at the Wyandotte County border. 69 Highway eventually splits and goes on to form its own separate highway that runs southbound down halfway between the Johnson County-Kansas City, Missouri border at State Line Road and North/Southbound I-435.
