Local Improvement District Projects

A Local Improvement District (LID) is a method by which a group of property owners can share in the cost of transportation infrastructure improvements. This involves improving the street, building sidewalks, and installing a stormwater management system. An LID can also be used to install sidewalks on existing streets that previously have been accepted for maintenance by the City.
