ITEM #9 CITY OF COLTON AGENDA REPORT FOR COUNCIL MEETING OF MARCH 20, 2007 TO: HONORABLE MAYOR AND CITY COUNCIL FROM: AMER JAKHER, P.E.; P.W. DIRECTOR / CITY ENGINEER SUBJECT: APPROVE RESOLUTION AMENDING THE FISCAL YEAR 2006/2007 CAPITAL IMRPOVEMENT PROGRAM (CIP) TO INCLUDE THE FREEWAY RAMP IMPROVEMENT PROJECT AND AUTHORIZE THE CITY MANAGER TO EXECUTE THE CORRESPONDING JOINT AGREEMENT AND ALL RELATED DOCUMENTS BETWEEN THE CITY OF COLTON AND CALTRANS DISTRICT 8. DATE: MARCH 14, 2007 BACKGROUND: Several meetings have been held between the City of Colton and Caltrans District 8 maintenance staff regarding the physical maintenance of the I-10 corridor through the City. The City of Colton requested that Caltrans pay particular attention to the deteriorating condition of several freeway access points. DISCUSSION/ANALYSIS: In response to the City's request and in light of shortages in the state budget for maintenance of the I-10, SR -215 and SR -210 , Caltrans has offered to begin a pilot program with the City of Colton. The program would be a joint effort between the City and Caltrans to improve the condition of the City's freeway on and off ramps. The scope of work for the proposed improvements will provide for application of rubberized slurry seal to all city freeway access ramps. Additionally, the program also intends to provide for the following needed drainage and accessibility improvements near City on and off ramps: 1) installation of a storm drain at the Sperry Drive off -ramp 2) construction of a new curb radius at the I-10/La Cadena on-ramp and 3) installation of an 8" cross -gutter at the 9th Street off -ramp. The cost estimate for these improvements totals $250,038.80 and is attached as Exhibit `A.' The program proposes to improve the following locations: • I-10 and Pepper • I-10 and Rancho • I-10 and La Cadena • I-10 and 9th Street • I-10 and Mt. Vernon • Sperry to Mt. Vernon off the I-10.
