Dulles Airport takes up a huge amount of space. This map shows the relation of Dulles to the communities that surround it.
The community of Pleasant Valley is represented by the blue dot in this map. Dulles is the large green space. From the map the distance between the two is apparent. When Dulles was constructed, communities like Pleasant Valley were threatened and in many cases the land was condemmed and acquired by the CAA.
This is a map of 18th century land grants for the Dulles area. Dulles appears in dark green, showing the large amount of land taken by the CAA in order to build the airport. Also shown with Dulles is the land grants that were made in the 1700s when Loudoun and Fairfax counties were being developed.
In order for Washington Dulles International Airport to be constructed a large amount of land was required. To do this, the CAA condemmed and acquired land that was primarily farmland. Communities like Pleasant Valley and Willard which existed prior to the airport being built ceased to exist after the airport began construction. The people who lived in these places had to leave and homes were destroyed or relocated. Willard has no remnants as the airport is directly on the same location, but Pleasant Valley has a few remnants remaining.
