A. Map of the City of Washington Showing Present Main Sewerage and Sewage Outfalls... (29.0 x 27.3"). Shows the extent of the sewer lines within the city as well as watershed boundaries for both storm water and sewage. Outside of the city, there is very good detail of land ownership, rivers, and topography - all of which would influence drainage and the city's sewer system. Condition: Vivid color with a number of fold separations that have mostly been closed on verso with archival tape, along with light toning primarily along the folds.
