CSS 614 Truck Impacted Intersections AGENDA MEMO DATE: November 22, 2011 TO: Mayor and Members of the City Council FROM: Office of the City Manager By: John Oskoui, P.E., Director of Public Works SUBJECT:CASH CONTRACT NO. S.S. 614 – TRUCK- IMPACTED INTERSECTIONS IMPROVEMENT PROJECT – PHASE 2 - APPROVE PLANS AND SPECIFICATIONS AND AUTHORIZE SOLICITATION FOR BIDS RECOMMENDATION That the City Council approve the plans and specifications and authorize solicitation for bids for Cash Contract No. S.S. 614 – Truck-Impacted Intersections Improvement Project – Phase 2. BACKGROUND The Truck Impacted Intersections Improvement Project is an effort initiated by the Gateway Cities Council of Governments (GCCOG) in 2000 with the intention of implementing improvements at intersections heavily traveled by trucks within various jurisdictions located throughout the sub region. The improvements are intended to enhance the movement of goods throughout the sub region by facilitating the movement of trucks through these intersections and include measures such as the reconstruction of curb returns to provide larger turning radii, the construction of additional turn lanes, the reconstruction or rehabilitation of intersections to provide a more durable surface to withstand the heavy traffic loads created by truck traffic and incidental traffic signal modifications. The first phase of the Truck Impacted Intersections Improvement Project included improvements to the Florence Avenue at Paramount Boulevard intersection, which were completed in 2008. The second phase of the Truck Impacted Intersections Improvement Project includes pavement rehabilitation of the Florence Avenue at I-5/I-605 on/off ramps/Little Lake Road and Studebaker Road intersections. In addition, this project will include the rehabilitation of the existing pavement on Florence Avenue between the I-5/I-605 on/off ramps/Little Lake Road and the east city limit (I-5 overpass), as well as Little Lake Road between Florence Avenue and the I-5/I-605 southbound on-ramp, Studebaker Road between Florence Avenue and the I-605 northbound on/off ramp intersection and Fairford Avenue between Florence Avenue and Dollison Drive. The GCCOG received Proposition C grant proceeds from the Los Angeles County Metropolitan Transportation Authority for the implementation of the Phase 2 projects and has distributed the grant funds among the local jurisdictions within the sub region in which Phase 2 projects are to be completed according to the estimated cost of the various projects. The City will receive $390,000 of the grant funds for the implementation of its project. CITY OF DOWNEY, CALIFORNIA Mayor and Members of the City Council Cash Contract No. S.S. 614 – Truck-Impacted Intersection Project - Phase 2 November 22, 2011 Page 2 This project consists of the rehabilitation of existing asphalt pavement, replacement of existing curb ramps and concrete spandrels and incidental pavement striping replacement within the project limits. The project covers approximately 0.6 mile of roadway. The attached project location map shows the location of the aforementioned project limits. DISCUSSION The condition of the existing pavement at these locations has become severely impacted over time, particularly due to heavy truck travel and the turning movements at the intersections. It is necessary to complete the rehabilitation of the existing pavement along these street segments and at the subject intersections in order to sustain the safe and efficient movement of people, goods and services. The Engineering Division staff has completed the preparation of the plans, specifications and construction cost estimate and the project is now ready for solicitation of construction bids. Per its agreement with the GCCOG, the City will be responsible for the construction, construction engineering and contract administration of this project. FINANCIAL IMPACT The total cost for the Truck-Impacted Intersections Improvement Project – Phase 2 is estimated at $2,125,000. This includes the cost of design, construction, construction inspection and management, and contingencies. Currently, $2,054,467 is programmed for this project in the FY 2011-12 Capital Improvement Program, consisting of the $390,000 grant from the GCCOG, $874,000 in proposition C Local Return, $600,467 in a Measure R grant to be received through the I-5 JPA and $190,000 in Gas Tax funds under Account No. 26-16608. A detailed cost estimate will be presented at the time of the award of the construction contract along with an appropriation of additional funds, if necessary.
