A capital improvement plan (CIP) is a city’s multi-year budget for building and replacing infrastructure. The water, sewer and wastewater sections list each project with its budget and the years it is funded, which makes them the earliest public signal that a plant, pump station or pipe network is about to be upgraded, usually two to four years before a contract is awarded.
