City of San Leandro <br />Meeting Date: June 3, 2013 <br />Staff Report <br />Agenda Section:File Number:13-217 CONSENT CALENDAR <br />Agenda Number:8.H. <br />TO:City Council <br />FROM:Chris Zapata <br />City Manager <br />BY:Uchenna Udemezue <br />Engineering & Transportation Director <br />FINANCE REVIEW:Not Applicable <br />TITLE:Staff Report for a Resolution Approving Plans and Specifications and <br />Authorizing the City Manager to Call for Bids for the Monarch Bay Drive Bridge <br />Repair Project, Project No. 150-38-324 <br />SUMMARY AND RECOMMENDATIONS <br />Staff recommends approving Plans and Specifications and Calling for Bids for the Monarch <br />Bay Drive Bridge Repair Project, Project No. 150-38-324. <br />BACKGROUND <br />The City owns and maintains several bridges, some of which are periodically inspected by <br />Caltrans. Recent inspection reports for the bridge that carries Monarch Bay Drive over the <br />Estudillo Canal (located immediately south of Marina Park) indicate that some of the concrete <br />is damaged and that the bank at the northern abutment has eroded to the point that the <br />abutment foundations are exposed. <br />The subject bridge is primarily used by pedestrians and bicyclists traveling on the Bay Trail . It <br />also serves as access for maintenance vehicles and as an emergency egress from the Heron <br />Bay neighborhood. <br />Analysis <br />This project will replace the damaged concrete and seal the bridge deck to reduce water entry <br />and future damage that may result. It will also protect the eroded banks by installing large <br />rocks or ‘rip rap’. The design of this work follows common engineering practice. <br />This work was contemplated as part of a 2005 project entitled “Neptune Drive Bridge <br />Protection”, but was abandoned due to lack of funding. Failure to repair the existing damage <br />could eventually result in an unsafe bridge. <br />Page 1 City of San Leandro Printed on 5/29/2013
