REPORT 6.10 Page 1 To the Honorable Mayor and City Council From the City Manager October 19, 2009 SUBJECT Professional service agreement with Moffatt & Nichol in the amount of $184,410.00 for levee certification documentation for the levees bordering the Redwood Shores Peninsula RECOMMENDA nON Approve, by motion, the professional service agreement with Moffatt & Nichol for levee certification documentation for the levee system protecting the Redwood Shores Peninsula in an amount not to exceed $184,410.00 and authorize the City Manager to increase the contract amount up to 10% if necessary. BACKGROUND In response to the Federal Emergency Management Agency's (FEMA) levee certification mandate, the city is undertaking a levee improvement and certification project to raise the height and certify the levees in the Redwood Shores area prior to September 2010, the effective date of the new Flood Insurance Rate Maps. On November 10, 2008, City Council approved an agreement with Moffatt & Nichol to perform an initial assessment of levee conditions as the first phase of the Exterior Levee Certification Program. The assessment is complete, and recommended levee improvements from the assessment are incorporated into the Redwood Shores Levee Maintenance Project, which is currently under permit review from various state and federal regulatory agencies before construction can begin. Concurrent with permitting and construction, Moffatt and Nichol will assist the city to prepare the certification documentation required by FEMA. In addition, FEMA has determined that segments of levee bordering the San Carlos Airport, partly owned by San Mateo County and City of San Carlos, must be improved and certified to provide complete flood protection for the Redwood Shores Peninsula. Levee improvement plans for these segments are also underway, with the city taking the lead on this multijurisdictional effort. Therefore, three separate certification packages will be prepared as part of this contract, one each for the following: . Redwood Shores Levee, which will be certified by the City of Redwood City; . County of San Mateo levee segment fronting the San Carlos Airport, which will be certified by the County; . San Carlos levee segment between Highway 101 and southwest of the San Carlos Airport, which will be certified by the City of San Carlos. The requirements of levee certification are outlined in Title 44 of the Code of Federal Regulations Section 65.10 and include evaluation of levee freeboard, closures, embankment protection, slope stability, settlement, interior drainage, and operation and maintenance procedures. The proposed agreement is available for review in the City Clerk's office.
