However, El Dorado County is part of the Sacramento Metropolitan Area because it is socially and economically integrated with the much larger Sacramento County and especially the City of Folsom. El Dorado Hills is recognized nationally for its high median household income, ranking 77th in CNN Money Magazine's best places to live in 2007, with the median household income for 2007 over $115,000.HistoryEl Dorado Hills lies about 18.6 miles from the 1848 gold find site in Coloma, the impetus for the California Gold Rush. Gold was washed down the South Fork of the American River, into areas now in El Dorado Hills and Folsom, but farming and ranching supplanted the Gold Rush. Portions of two Pony Express routes in this area from 1860-1861 remain as modern El Dorado Hills roads. El Dorado Hills includes the longest surviving section of the Lincoln Highway, the first U.S. transcontinental highway. This section, part of the Pioneer Branch, passes through historic Clarksville and is the predecessor of the modern US 50 route.
