A Corridor Improvement Authority allows the use of tax increment financing to make capital improvements within an established commercial district. It allows communities that already have Downtown Development Authorities (DDAs) to extend similar benefits to aging commercial corridors outside the DDA district or that extend through more than one municipality.
A CID is designed to assist economic development and redevelopment in established commercial districts. It allows communities to combine tax dollars from a variety of sources to leverage economic development dollars.
