ECT will present the green infrastructure plant selection tool recently launched for the Milwaukee Metropolitan Sewerage District (District). The assignment was organized to help the District's project partners with the selection of plants for green infrastructure applications. The Tool is an easy-to-use excel spreadsheet intended for broad distribution. The District recognizes the important role that plants play in green infrastructure but also understands that the conditions they must survive can be challenging. This tool allows users to select those conditions and narrow down a master list of plants to reveal the ones most suited to their particular site. Options for selecting plants for an ornamental or naturalized planting approach are provided as well as cost and maintenance considerations.
