Abstract:

In February, 1791, Major Peter Charles L’Enfant was commissioned to determine the locations of the buildings that would be needed by the federal government when it relocated from Philadelphia to the new Federal City on the banks of the Potomac in 1800. Within five months he had conceived, modified, redesigned, and received presidential approval of the plan of a new city like no other on earth. Andrew Ellicott, Surveyor General of the United States, worked closely with L’Enfant in the laying-out process, which resulted in numerous modifications of the original design. Ellicott’s survey report, including a map showing the centerlines of streets and avenues, demonstrates the limitations of eighteenth century surveyors’ practices when faced with the task of drawing a complex plan diagram on a six thousand acre landscape. Ellicott’s map makes it possible for us to determine the sequence of the measurements, and to discover which of the significant elements of the L’Enfant Plan were located intentionally, and which locations were dictated by his chosen geometry. This question must be dealt with in any full consideration of the designer’s intentions and accomplishments. This presentation, will discuss the effects of the eighteenth century science of surveying on the design of Washington, DC.
