In all, nearly 800 structures were inspected and an Inventory Data Sheet filled out. Additionally, all utilities designated along the alignment of the 55,000 feet of new sanitary sewers were located.

Also included were the preparation of easement plats for completion of the project.
The Green Infrastructure Project employed green drainage improvements that included bioretention, pervious pavers, sidewalk planters, and street islands.
