*This state-local partnership project will receive funding from RAMP, Responsible Acceleration of Maintenance and Partnerships towards the approximately $2.7 million in drainage improvements. RAMP is better coordinating project expenditures and available funding. Under the RAMP program, CDOT will fund multi-year and partnership projects based on year of expenditure, rather than saving for the full amount of a project before construction begins.
