6.1.A. - Page 1 REPORT To the Honorable Mayor and City Council From the City Manager December 12, 2016 SUBJECT Professional Services Design Agreement — 2017 Redwood Creek Improvement Project RECOMMENDATION By motion, approve and authorize the City Manager to execute the Professional Design Services Agreement with Wood Rodgers, Inc. in the amount of $235,674 for the design of the 2017 Redwood Creek Improvement Project, and to increase the contract amount, if necessary, up to 10% of the amount awarded. Confirm determination that the agreement is not a "project" subject to the California Environmental Quality Act (CEQA) BACKGROUND Most stormwater in the City drains by gravity to Redwood Creek or one of its tributaries: Kensington Branch, Stulsaft Branch, Jefferson Branch, and Emerald Branch. These branches converge one by one to finally discharge into San Francisco Bay near Bradford Street and total about 8 miles in length collectively. Certain portions of Redwood Creek and its tributaries in the lower area of the City have been improved by the construction of concrete lined channels and box culverts around the mid -1960's. Since then, aside from some emergency repairs, the creek walls and channels have not been improved. Over time, these concrete structures developed deficiencies such as cracking, spalling, exposed, damaged and/or corroded reinforcing steel, joint filler deterioration, horizontal/vertical displacements in concrete joints, and wall rotations. Repair and replacement of the concrete structures are necessary to ensure continued reliability of the storm water collection system. This project is the first improvement project of a new multi-year improvement program for Redwood Creek. In the fall of 2015, the City obtained permits from the regulating agencies, which are the US Army Corps of Engineers (USACE), California Regional Water Quality Control Board (RWQCB), and California Department of Fish and Wildlife (CDFW) to work within Redwood Creek and its branches. The permits allow for repair, rehabilitation or replacement within the concrete channel and concrete box culvert portions of the creek only. No work is authorized within natural channels. This specialty project requires the structural engineering and construction services by an experienced engineering consulting firm. The selected expert Consultant will prepare the plans and specifications, cost estimates, contract documents for bidding, provide bid
