Scope and Content Notes:
This series contains maps that were created or used during the Three Rivers Second Nature Project. The legal-sized maps are housed in one box and roughly focus on the same topic, which is finalized, or working, copies of the areas of the rivers and streams that were examined. The data collected maps convey information that was obtained during the course of the waterway evaluation, such as present pollutant levels. Planning maps convey information about the planning process of the waterway evaluations, such as possible areas to build up.
