A major oil refining company considered purchasing 750 acres for development of an oil tank farm directly across the Potomac River from Mount Vernon.
The Accokeek Foundation was formed to organize efforts working toward the preservation of the Maryland shoreline. Involved were the Moyaone Association, consisting of property owners in the Accokeek area; the Piscataway Company, a real estate firm formed by several property owners to preserve the rural character of the land by purchasing larger tracts with restrictive covenants; the Alice Ferguson Foundation, created to oversee Accokeek land holdings bequeathed to a small group of residents by Alice Ferguson; the National Park Service; Smithsonian Institution; and the Mount Vernon Ladies’ Association. To help jumpstart preservation efforts, France Bolton donated her 485 acres to the Accokeek Foundation.
Washington Suburban Sanitary Commission (WSSC), using eminent domain, announced its plans to build a three-story sewage treatment plant across from Mount Vernon. In an attempt to minimize criticism, WSSC agreed to make the plant a replica of Mount Vernon. Congresswoman Frances Payne Bolton defeated the WSSC initiative through her influence in Congress and new partnerships.
Public Law 87-362 was passed and signed by President John F. Kennedy, leading to the establishment of Piscataway Park, administered by the National Park Service. The legislation allowed Congress to acquire land through fee simple terms for the national park and for the acquisition of scenic easements over lands associated with the hills beyond. Easements were made possible through cooperation between the federal government and the Maryland state legislature by authorizing real estate tax credits and income tax deductions for donated scenic easements. The bill also authorized the National Park Service to accept donations of land from the Accokeek Foundation and the Alice Ferguson Foundation.
Congress appropriated $1.5 million and Piscataway Park began to take shape.
The National Park Service received a transfer of scenic easements on 1,300 acres of land outside of the park’s fee simple area. It also negotiated the purchase of the final 106 acres remaining in the park’s fee simple area. Today, the park has grown to approximately 5,000 acres.
President Gerald Ford signed Public Law 93-444 into law, providing additional protection for the permanent preservation of Piscataway National Park.
Development proposals for surrounding lands threatened the historic, rural qualities of the larger vista. A 52-story building called Port America was planned for a site just south of the Woodrow Wilson Bridge in Maryland’s Prince George’s County. Thankfully, the Federal Aviation Administration ruled that the proposed building was an unacceptable air safety hazard.
With assistance from the Trust for Public Land, EDAW, a landscape architecture and planning firm, prepared a visual simulation and viewshed study for Mount Vernon. It determined which areas of the viewshed would be adversely affected by buildings of varying heights.
A result of the 1991 viewshed study was Senate Bill 1703 (Piscataway National Park Expansion Act of 1993). It was introduced by Senator Paul Sarbanes of Maryland and signed into law by President Bill Clinton. The bill authorized the expansion of park boundaries and enabled federal acquisition of unprotected properties within the historic viewshed. However, no money was appropriated to help with property acquisition.
The Mount Vernon Ladies' Association purchased an 18th-century house and 73 shoreline acres from Mr. and Mrs. Grima Johnson, to prevent the land from falling into the hands of a developer. The Association sold the home and 10 acres to Tim and Liz Cullen.
The Association, The Trust for Public Land, and the National Park Service created strong easements on the Cullen property, appraised the remaining land, and determined a fair market price.
Approximately 63 undeveloped acres were sold to the National Park Service by the Association and The Trust for Public Land.
Mount Vernon purchased the LeCrone property.
Mount Vernon acquired a one-acre parcel known as the Stalker property. The Stalker property was of critical importance. It lies along the Capt. John Smith National Historic Trail and is entirely surrounded by Piscataway National Park. The Stalker property also lies prominently within the viewshed of Mount Vernon. At the time the Stalker property was offered for sale, the MVLA, in partnership with The Conservation Fund, acquired the property with the understanding that the National Park Service would acquire the property from the MVLA.
Mount Vernon sold the Stalker and LeCrone properties.
A seller offered a 75-acre parcel in Charles County to the National Park Service and Accokeek Foundation. The parcel is directly across the river from Mount Vernon, yet falls outside of the Piscataway National Park and is not within Mount Vernon’s vulnerable viewshed. The parcel is still for sale and is being closely monitored.
Prince George’s County passed act CB-73-2017 which requires realtors to disclose the National Park Service scenic easements to potential homebuyers within the viewshed. The passage of this act strengthens some of the older scenic easements, which were previously not required by law to be revealed during real estate transactions.
