6.1.B. - Page 1 rcc ru rcT To the Honorable Mayor and City Council From the City Manager April 25, 2016 SUBJECT Invoice for Sediment Removal for Holly/101 East Channel in Redwood City RECOMMENDATION By motion, approve and authorize the City Manager to pay an invoice in the amount of $286,287.60 to the City of San Carlos for sediment removal work done on the City of Redwood City portion of the Holly/101 East Channel BACKGROUND The Holly/101 East drainage channel runs along Shoreway Road, and is encompassed by Holly Street and the Highway 101 North on-ramp. San Carlos and Redwood City have shared ownership of this channel. The downstream portion of the channel is in Redwood City's jurisdiction. San Carlos completed a drainage study and identified that sediment and vegetation build up in the channel needed to be removed to have better storm water flow into the storm water detention pond in Redwood City. San Carlos offered to file the necessary permits and complete the sediment removal work on both the San Carlos and the Redwood City portions of the channel. Redwood City agreed to share the costs for Redwood City's portion of the drainage channel work. ANALYSIS Staff determined that this shared-resources approach between two neighboring agencies was the most cost-effective way to address a complex and time consuming project. Redwood City recently completed sediment removal work at Cordilleras Creek and part of it was under San Carlos' jurisdiction. For this project, San Carlos shared the cost of the sediment removal work while Redwood City was the lead agency which executed the work. Redwood City agreed to allow San Carlos to take the lead on the Holly/101 East drainage channel work. San Carlos prepared plans, obtained the necessary permits from regulatory agencies and completed the sediment removal work on October 30, 2015. ALTERNATIVES No alternative available as the work has already been completed. FISCAL IMPACT The majority of the funds for the payment of this invoice ($279,000) are available in the Capital Improvement Projects Fund — Holly Street Sediment Removal, 357-75601. The remaining balance of $7,287.60 can be paid through the Contingency Fund, 357-76000.
