This series contains maps that were used during the Nine Mile Run Greenway project. The "Ledger Sized" maps consist mainly of maps with their printed reports concerning population, waste water run-off, pedestrian routes, and tributaries related to the Nine Mile Run site. The oversized maps are housed in five separate file-folders. Of note is the neighborhoods map folder that shows the Nine Mile Run Greenway neighborhood borders and the municipality that is responsible for the various sections of the Nine Mile Run Greenway area. The neighborhoods portrayed include, but are not limited to, the City of Pittsburgh, Swissvale, Edgewood, and Wilkinsburg.
