This polygon feature class surrounds the benefiting properties within local improvement districts (LIDs) that have been formed by City Council since 2001. Most LIDs are for street improvements, but LIDs have also been formed for aerial tram, streetcar, water main and sanitary sewer improvements. "Completed" in the LID Status field refers to LIDs for which final assessment has been imposed by City Council; "Pending Completion" refers to LIDs which are in the design or construction phases, or which construction but not final assessment is complete
