Title A name given to the resource Potomac Flats Reclaimed Description An account of the resource In 1870 the Army Corps of Engineers, headed by Major Nathaniel Michler, began dredging the <a href="http://mallhistory.org/items/show/424">Potomac</a> to remove silt and improve ship traffic. Dredged material was dumped into the tidal flats along the <a href="http://mallhistory.org/items/show/378">Washington waterfront</a>. In 1875 the project was expanded to include reclaiming the flats. The initial experiment lasted until 1882, but the reclamation continued until August 30, 1911, by which time contractors had moved over 12 million cubic yards of material from the river to the flats, <a href="http://mallhistory.org/items/show/321">creating Potomac Park.</a> Date A point or period of time associated with an event in the lifecycle of the resource 07/09/1875 Coverage The spatial or temporal topic of the resource, the spatial applicability of the resource, or the jurisdiction under which the resource is relevant 1860-1889 Source A related resource from which the described resource is derived Library of Congress Prints and Photographs Division. <a href="http://www.loc.gov/pictures/item/dc0448.photos.025235p/">View original</a>. building the mall design & monuments environment
