POST REHAB CONDITION COMPARISON
CURRENT CONDITIONS COMPARED TO FORECASTED CONDITIONS
•Streets are better than national average today
•City’s current funding of $800K/YR is forecasted to result in a PCI of
approximately 67 and a backlog of 10% in 5 years.
•The funding level required to maintain the current backlog is 5.6M/yr.
•Strive to keep a PCI above the National Average of 65 and a backlog
below 9%.
•Keep your good roads in good shape! Strategic and proactive annual
preventive maintenance and major rehabilitation saves money.
•City should resurvey streets on no less than a 5-year cycle to update
condition data and track pavement performance.
