6.1.A. - Page 1 REPORT To the Honorable Mayor and City Council From the City Manager October 2, 2017 SUBJECT Memorandum of Understanding between the City of Redwood City, City of Menlo Park, Town of Atherton, and County of San Mateo County for the planning, designing and permitting of flood protection measures within the Bayfront Canal and Atherton Channel Watershed RECOMMENDATION By motion, authorize the City Manager to (1) proceed with the planning, designing and permitting of flood protection measures within the Bayfront Canal and Atherton Channel Watershed, and (2) execute the Memorandum of Understanding (MOU) between the City of Redwood City, City of Menlo Park, Town of Atherton, and County of San Mateo, with additions, clarifications and other changes as the City Manager deems appropriate or necessary, or an alternative agreement, in order to effectuate the above -stated purpose and allow cost-sharing between any resulting participating entities BACKGROUND The Bayfront Canal and Atherton Channel, together, collect stormwater from a watershed that includes the City of Redwood City, City of Menlo Park, Town of Atherton, Town of Woodside and unincorporated San Mateo County before discharging the stormwater flows to the San Francisco Bay at Flood Slough. The Bayfront Canal begins in Redwood City by Douglas Court and runs west to east along the southern edge of salt ponds owned and operated by Cargill until reaching Flood Slough near Marsh Road. The Bayfront Canal receives the majority of its runoff from the areas south of US Highway 101, including areas in Redwood City, Menlo Park, and the County unincorporated area of North Fair Oaks. The Atherton Channel discharges directly into the Bayfront Canal near Marsh Road before the Bayfront Canal drains into Flood Slough and the Bay adjacent to Bayfront Bedwell Park. The Atherton Channel receives runoff from the Cities of Redwood City and Menlo Park, the Towns of Woodside and Atherton, and the unincorporated areas of San Mateo County. The drainage areas along the Bayfront Canal and Atherton Channel are subject to frequent flooding due to capacity constraints of the Bayfront Canal and Atherton Channel. These capacity issues generally arise when high tides align with large storm events. During a flood event, areas in Atherton, Redwood City, Menlo Park, and the County are impacted by flooded streets, residences, and businesses particularly in areas adjacent to the Bayfront Canal and Atherton Channel.
