A capital improvement plan (CIP) is a city’s multi-year budget for building and replacing infrastructure.

Sources and methodology
Budgets and years are as published in Springfield’s capital improvement plan or adopted budget. Klarifi extracts the water, sewer and wastewater line items from the published document, keeps the page reference for each one, and assigns a project type from the title and description with a keyword classifier. Figures are planning budgets, not awarded contracts, and can change when a plan is re-adopted.
