DEPT. 19,662 12/09/08 ENG APPROPRIATION OF FUNDS AND AUTHORIZATION TO ADVERTISE FOR BIDS FOR THE REPAIR OF PALOMAR AIRPORT ROAD BRIDGE OVER CARLSBAD BOULEVARD, PROJECT NO. 4700 DEPT. HEAD ^-f 5 CITYATTY. <^25' CITY MGR.UA— RECOMMENDED ACTION: Adopt Resolution No. 2008-326 appropriating funds and authorizing advertisement for bids for the Repair of Palomar Airport Road Bridge over Carlsbad Boulevard, Project No. 4700. ITEM EXPLANATION: Richard Brady and Associates were retained to investigate the condition of the Palomar Airport Road Bridge over Carlsbad Boulevard, which was built in 1952. Investigations have revealed that the steel guardrails are moderately to severely corroded and need to be replaced. In addition, corrosion of reinforcing steel has caused the overlying concrete to crack and spall in some areas of the bridge. Richard Brady and Associates have recommended that the damaged concrete areas be removed, corroded reinforcing steel be replaced, and resulting voids and cracks filled with epoxy mortar. As a preventative measure, sacrificial anodes and corrosion inhibitors have been recommended. The sacrificial anodes are designed to neutralize new corrosion by introducing zinc anodes which are more reactive, and therefore corrode preferentially, to the reinforcing steel. The corrosion inhibitor is a spray-on chemical coating for the concrete structure which forms a protective layer that mitigates the corrosion process. This project will repair the Palomar Airport Road Bridge over Carlsbad Boulevard utilizing the repair methodologies outlined above as recommended by Richard Brady and Associates. ENVIRONMENTAL IMPACT: This project is a Class 2 categorical exemption (replacement or reconstruction of existing structures or facilities) and is, therefore, exempt from environmental review pursuant to Section 15302 of the California Environmental Quality Act (CEQA). FISCAL IMPACT: The original scope of Capital Improvement Project No. 4700 was to repair the guardrail on the Palomar Airport Road Bridge over Carlsbad Boulevard. As a result, only $130,000 was budgeted in the General Capital Construction Fund for completion of the guardrail repair as indicated below.

These funds currently reside in the TransNet Fund and the Proposition 42 Fund. The Proposition 42 funds remaining in the TransNet Fund are no longer needed for TransNet projects. Staff is recommending transferring the remaining Proposition 42 funds residing in the TransNet Fund ($827,990) to the Proposition 42 Fund to complete the project. The contract for this project will require prevailing wages be paid per sections 1770, 1773, and 1773.1 of the Labor Code. EXHIBITS: 1. Location Map. 2.
