PENNSYLVANIA AVENUE 9th Street SE to the Anacostia River 10th Street to 11th Street

1903	Historic rowhouses continued the street pattern found in the 900 block into the western portion of the northern 1000 block.  Six of these rowhomes, built by William Yost, date to 1894, and display characteristics of the Richardsonian Romanesque architectural style.  Richardsonian Romanesque rowhouses designed by William Yost.
1954	The density of this block increased between 1903 and 1954, particularly along 10th and 11th Streets SE.  Residential use remained the dominant function of the rowhouse structures.
1998	The diagonal cut of Pennsylvania creates several triangles of open space along the avenue, enhancing the boulevard-like feel established by the wide, well-maintained median. This  park-like, median space at the 1000 block, dotted with mature trees and defined on two sides by a well-maintained boxwood hedge, complements the pleasant visual quality of the area.   On the eastern corner, a Texaco Station disrupts the century old character with a variation in height, style, setback and an excessive amount of paved surface.
