REPORT <br />To the Honorable Mayor and City Council <br />From the City Manager <br /> <br />February 13, 2017 <br /> <br />SUBJECT <br />Final Acceptance – Cathodic Protection Upgrade of the Recycled Water First Steps <br />Pipeline Project <br /> <br />RECOMMENDATION <br />Accept, by motion, the Cathodic Protection Upgrade of the Recycled Water First Steps <br />Pipeline Project, authorize the release of bonds and retention according to City <br />procedures, and find that the project is exempt from the California Environmental <br />Quality Act (CEQA) under CEQA Guidelines Section 15302(c) (replacement or <br />reconstruction of existing utility system and/or facilities) <br /> <br />BACKGROUND <br />The City periodically replaces anodes and test stations of recycled water and potable <br />water infrastructure to ensure the continued reliability of the system. Galvanic anodes <br />have an approximate design life of 25 to 30 years. The Recycled Water First Step <br />Pipelines were built in the late 1980s. Therefore, the galvanic anodes are due for a <br />replacement. Staff periodically identifies galvanic anodes that are at or close to the end <br />of its design life and target those cathodic protection stations for improvement. These <br />improvements extend the life of the cathodic protection stations another 25 to 30 years. <br /> <br />ANALYSIS <br />On May 9, 2016 the City Council awarded the construction contract for the Recycle <br />Water System Development Program to Corrpro Companies, Inc. of Hayward for their <br />responsive and responsible low bid of $129,842.0. Forty five anode test station <br />locations were improved with installation of new zinc anodes, replacement of test station <br />boards and replacement of valve boxes. The project area included Marine Parkway, <br />Shearwater Parkway, Canvasback Way, Embarcadero and Redwood Shores Parkway <br />within Redwood City corporate limits. Attachment A provides a map of the project area. <br />The corrosiveness of the soil within Redwood Shores is identified as extremely high and <br />therefore the anode replacement was absolutely necessary as most of them were <br />approaching the end of their useful life. <br />The project has been completed and approved by the City Engineer in accordance with <br />the plans and specifications and within the timeframe allowed by contract for a total cost <br />of $126,421.00 which is 2.63% less than the original bid amount. One change order was <br />issued for the credit amount of $3,421.00 resulting from adjustment of bid quantities. <br />6.2.A. - Page 1
