Calvert County is a county located in the U.S. state of Maryland. As of the 2010 census, the population was 88,737.[1] Its county seat is Prince Frederick.[2] The county's name is derived from the family name of the Barons of Baltimore, the proprietors of the English Colony of Maryland.

Calvert County is included in the Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area. It occupies the Calvert Peninsula, which is bordered on the east by Chesapeake Bay and on the west by the Patuxent River.

Calvert County is part of the Southern Maryland region. The county has one of the highest median household incomes in the United States.[3]


First colonized as part of Charles County (much larger than the present-day Charles County) around 1650,[4] it was renamed. Patuxent County was established in 1654 by an Order in Council.[5] In 1658 the county was renamed Calvert County.[6] It is one of the older counties in Maryland, after St. Mary's County, Kent County and Anne Arundel County.

Once made up primarily of farms and tobacco fields, the county has become a fast-growing exurban neighbor of Washington. Many home prices have nearly quadrupled in the past decade, with many four-bedroom homes in the northern half of the county averaging over $1,000,000. The popular weekend resort towns of Solomons, Chesapeake Beach, and North Beach are notable.

The county has a number of properties on the National Register of Historic Places.[7]

Politics and government

Calvert County is governed by a group of five county commissioners, the traditional form of county government in the State of Maryland.

Board of County Commissioners
Position Name Affiliation District
  President Tom Hejl Republican At-Large
  Vice President Evan K. Slaughenhoupt Jr. Republican 3
  Commissioner Mike Hart Republican 1
  Commissioner Pat Nutter Republican 2
  Commissioner Steven R. Weems Republican At Large

In Presidential elections Calvert County has historically and at present leaned strongly towards the Republican Party. It was won by that party in every election from 1884 to 1936 - with the sequence broken in 1940 due to local support for Franklin Delano Roosevelt's efforts at helping Britain in World War II[8] - and in modern times no Democratic presidential nominee has won Calvert County since Jimmy Carter did so in 1976.

It is part of the 5th Congressional District, along with much of Southern Maryland. The current representative is Democratic House Minority Whip Steny Hoyer.

Calvert County is served by Calvert County Public Schools. The county's education system consists of 13 elementary schools, six middle schools, four high schools, vocational education center, and a variety of other facilities.


The main artery serving Calvert County is Maryland Route 4 (which begins in Washington, D.C. as Pennsylvania Avenue before crossing into Prince George's County, Maryland and Anne Arundel County, Maryland). Route 4 in Calvert County begins at the very northern tip of the county at Lyons Creek, approximately 3 miles north of Dunkirk. At Sunderland, Route 4 meets Maryland Route 2 (traveling south as a two-lane road from Annapolis) and the two roads merge as Maryland Route 2-4. Route 2-4 continues south through Prince Frederick, St. Leonard and Lusby. At Solomons, Routes 2 and 4 split again, with Route 2 heading towards downtown Solomons and Route 4 crossing the Patuxent River at the Governor Thomas Johnson Bridge into St. Mary's County.

Route 2-4 is designated Solomons Island Road throughout much of the county, with the section south of Prince Frederick being recently renamed Louis Goldstein Highway in memory of Louis L. Goldstein, the former comptroller of Maryland and Calvert County resident.

In the 1970s and 1980s, Route 2-4 underwent an extensive expansion project, with the formerly two-lane road becoming a four-lane dual highway. Certain portions of the highway were re-aligned, with the former roadway becoming Maryland Route 765. The final portion of the dualized Route 2-4 between St. Leonard and Solomons was completed in 1988. In 2009, a portion of Route 2-4 in Prince Frederick was expanded to 3 lines, along with sidewalks added.

Other major roadways in Calvert County include:



Census-designated places

The Census Bureau recognizes the following census-designated places in the county:

Dunkirk, Huntingtown, Lusby, Owings, Prince Frederick, St. Leonard and Solomons have all been designated by Calvert County government as being "town centers". The "town center" designation means while these communities may not have incorporated central governments, they do have specified boundaries surrounding the central business and residential areas for zoning purposes. The reason behind the "town center" designation is to cluster new development within established areas with existing infrastructure, thus discouraging urban sprawl. The implementation of the "town center" concept in Calvert County over the past two decades has for the most part been successful in preserving rural and agricultural areas outside the designated "town centers", and stands as a key example of the smart growth planning strategy.[24][25]
