There are twenty-six (26) streets included in this project and the Pavement Condition Index (PCI) ratings for these streets ranges from 60 to 100 with the exception of three (3) streets that have a PCI of 29, 39, and 52. A PCI rating of 86-100 means excellent condition, 71-85 is very good, 56-70 is good, 41-55 is fair, 26-40 is poor, 11-25 is very poor, and 0-10 is failing. The PCI rating is based on the Pavement Management Program Final Report (dated September 2004) prepared by GK and Associates for the City of Colton. The approximate length of aforementioned trenches is 30,000 lineal feet. Locations of these streets are shown on the attached map as Exhibit A. Pictures of some of the streets are attached also as Exhibit B. ANALYSIS/DISCUSSION: The cost to pave the trenches for this project is estimated at $720,000.
