Calvert County is a county located in the U.S. state of Maryland. It occupies the Calvert Peninsula which is bordered on the east by the Chesapeake Bay and on the west by the Patuxent River. As of the 2010 census, the population was 88,737.[1] Its county seat is Prince Frederick, Maryland.[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 part of the Southern Maryland region. Calvert County's residents are among the highest median household-income in the United States.[3]

Calvert County is one of the several Maryland counties that make up part of the Washington Metropolitan Area and the Baltimore-Washington Metropolitan Area.

Business and Industry[edit]

Calvert County is the home of the notable Calvert Cliffs Nuclear Power Plant at Lusby.

The Chesapeake Biological Laboratory, part of the University of Maryland Center for Environmental Science is located in Solomons, Maryland.

A branch of the United States Naval Research Laboratory is located at Chesapeake Beach.

The Cove Point LNG Terminal is located near Lusby, Maryland, on the western shore of the Chesapeake Bay.

The Patuxent River Naval Air Station is located immediately to the south of Calvert County, in St. Mary's County.

First settled as part of Charles County (much larger than the present-day Charles County, Maryland) around 1650,[5] it was renamed. Patuxent County was established in 1654 by an Order in Council.[6] In 1658 the county was renamed Calvert County.[7] 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 was/is slowly claiming its place as 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 Solomons, Maryland, Chesapeake Beach, Maryland and North Beach, Maryland are notable.

The county has a number of properties on the National Register of Historic Places.[8]

Law and government[edit]

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
  Commissioner Gerald W. "Jerry" Clark Republican 1
  Vice President Steven R. Weems Republican At-Large
  Commissioner Susan Shaw Republican 2
  President Pat Nutter Republican At-Large
  Commissioner Evan Slaughenhoupt Republican 3

The county regularly elects prominent Democrats, including the second most powerful Democrat in the United States House of Representatives Steny H. Hoyer and State Senate President Thomas V. "Mike" Miller, Jr. (D). However, the County Commissioners are entirely Republican.

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


According to the 2000 census, the county has a total area of 345.09 square miles (893.8 km2), of which 215.17 square miles (557.3 km2) (or 62.35%) is land and 129.91 square miles (336.5 km2) (or 37.65%) is water.[9]


Calvert County is served by Calvert County Public Schools. The county's education system consists of 13 elementary schools, 6 middle schools, 4 high schools, vocational education center, and a variety of other facilities.


Calvert County lies in the Humid subtropical climate zone, with hot, humid summers and mild to chilly winters with plentiful precipitation year-round. Its proximity to the Chesapeake Bay has a moderating effect on temperatures compared with locales further inland.

Notable residents[edit]

Movies and Television[edit]

Calvert County has been the setting for several movies and television programs. The opening scene of the 1993 Clint Eastwood movie In the Line of Fire was filmed at Flag Harbor Marina in St. Leonard.[citation needed] More recently, the Calvert County Sheriff's Department has been featured on several reality television programs, including Speeders on the truTV network and MTV's Busted.[citation needed]

There were 25,447 households out of which 41.70% had children under the age of 18 living with them, 64.80% were married couples living together, 9.90% had a female householder with no husband present, and 20.80% were non-families. 16.30% of all households were made up of individuals and 5.70% had someone living alone who was 65 years of age or older. The average household size was 2.91 and the average family size was 3.26.

In the county the population was spread out with 29.60% under the age of 18, 6.40% from 18 to 24, 31.70% from 25 to 44, 23.40% from 45 to 64, and 8.90% who were 65 years of age or older.

The median income for a household in the county was $65,945, and the median income for a family was $71,545 (these figures had risen to $88,989 and $100,229 respectively as of a 2007 estimate[14]). Males had a median income of $48,664 versus $32,265 for females. The per capita income for the county was $25,410.

Cities and towns[edit]

Calvert County includes two municipalities, both classified as towns under Maryland law:

  1. Chesapeake Beach (incorporated 1886)
  2. North Beach (incorporated 1910)

Unincorporated areas are also considered as towns by many people and listed in many collections of towns, but they lack local government. Various organizations, such as the United States Census Bureau, the United States Postal Service, and local chambers of commerce, define the communities they wish to recognize differently, and since they are not incorporated, their boundaries have no official status outside the organizations in question. The Census Bureau recognizes the following census-designated places in the county:

  1. Calvert Beach-Long Beach (a combination of the communities of Calvert Beach and Long Beach recognized as a unit by many people)
  2. Chesapeake Ranch Estates-Drum Point (a combination of the communities of Chesapeake Ranch Estates and Drum Point recognized as a unit by the Census Bureau)
  3. Dunkirk
  4. Huntingtown
  5. Lusby
  6. Owings
  7. Prince Frederick
  8. St. Leonard
  9. Solomons

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.[15][16]

Other unincorporated places not listed as Census-Designated Places but known in the area include:

  1. Barstow
  2. Broomes Island
  3. Dares Beach
  4. Dowell
  5. Lower Marlboro
  6. Port Republic
  7. Sunderland

Highways and Roads[edit]

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.
