CityCouncil | 2007-08-07 | 3 | The Public Works Director responded in the affirmative; stated work would include preventative maintenance of exposed concrete. Councilmember deHaan stated newspaper articles have addressed the current situation with the Minneapolis bridges; requested information on the condition of Alameda bridges and the Tube. The Public Works Director stated Alameda bridges and the Tube are not unsafe; CalTrans completed the Webster Street and Posey Tube retrofitting in 2003; the retrofitting brought both tubes to a "no collapse" standard, which means that the tubes would not collapse in the event of an 8.0 earthquake on the Hayward Fault; service is not guaranteed; the Park Street, Fruitvale Avenue and High Street bridges are maintained by the County; retrofitting is anticipated to be completed by the end of 2009; efforts are being made to secure funding for a lifeline for the Fruitvale Avenue bridge the Bay Farm Island bridge was retrofitted by the State in 1998; currently, the Ballena Boulevard bridge is being seismically retrofitted; a federal grant is providing 90% funding; hopefully, a State grant will provide the other 10%. Councilmember deHaan stated that he is concerned that the bridges and the Tube might not be the City's lifeline and would not provide a connection to the mainland, Oakland and the rest of the East Bay. Vice Mayor Tam requested clarification on: 1) the process that CalTrans uses to rate a bridge deficient, 2) the ratings of the Park Street, Fruitvale Avenue, and High Street bridges, and 3) the frequency of bridge inspections. The Public Works Director responded the bridges are inspected every two years; stated the rating is based on several different factors. i the High Street Bridge is rated 46.4 on a rating of one to a hundred. Vice Mayor Tam inquired whether below 50 is deficient. The Public Works Director responded below 50 is considered structurally deficient but does not mean the bridge is unsafe to travel; stated Alameda bridges score low because detour length is one of the major rating indices; decking, approach, and lane width are considered; structurally, the High Street bridge is in very good condition. Vice Mayor Tam inquired whether the foundation is inspected, to which the Public Works Director responded in the affirmative.
