Item #15 CITY OF COLTON AGENDA REPORT FOR THE CITY COUNCIL MEETING OF May 7,2002 TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS FROM: AMER JAKHER, P.E., CITY ENGINEER I q5 SUBJECT: AUTHORIZATION REQUEST TO REPROGRAM $87,380.00 OF TRAFFIC CONGESTION RELIEF FUND, AND AUTHORIZATION REQUEST TO SOLICIT PUBLIC BIDS FOR THE 200112002 PAVEMENT RECONSTRUCTION PROJECT— ALSTON AVENUE DATE: APRIL 29, 2002 BACKGROUND: The City currently has $340,000.00 in the Traffic Congestion Relief Fund. This amount is old funding whose accessibility expires at fiscal year-end; all of the funds in this account must be expended by June 30, 2002. Two Reche Canyon Traffic Signals, currently out for Bid, will use $250,000.00 of the TCRF monies. The remaining $87,380.00 originally scheduled for the MichigonlMill Traffic Signal and the Watwood Street Traffic Warning (see Exhibit "A") will be lost to the City of Colton; neither of the originally funded projects can be developed, engineered, designed, bid and constructed within the above -noted time frame.

Based upon an extensive field review, Alston Avenue is one of Colton's streets which were paved with the above -noted 2 1/2" AC over native. Per the above -noted field review, staff determined that the pavement surface, and that of the entire street section of Alston Avenue is currently failing; within the last year, the rate of decline in the pavement condition has measurably accelerated. What was originally scheduled for pavement rehabilitation now requires a complete reconstruction. The proposed reconstruction process involves the removal of the existing deteriorated Asphalt surface. along with the excavation of approximately five inches (5") of the compacted native soil. After compacting the remaining soil at the bonom, a minimum course of four inches (4") of Class 11 base will be installed followed by a three inch (3") course of Asphalt Paving. The new street
