SCOPE OF SERVICES A. PROJECT DESCRIPTION The City of Redwood City (City) seeks to improve the concrete lined sections of Redwood Creek in connection with the 2017 Redwood Creek Improvement Project. Over time, some sections of concrete lined channels and box culverts developed deficiencies such as cracking, spalling, exposed, damaged and/or corroded reinforcing steel, joint filler deterioration, horizontal/vertical joint displacements, and wall rotations. The City would like to repair and rehabilitate these concrete structures to improve their conditions. As a result, the City obtained permits from the US Army Corps of Engineers, California Regional Water Quality Control Board, and California Department of Fish and Wildlife to work on the improved portions of Redwood Creek. B. SCOPE OF WORK In 2016, the City contracted with BKF Engineers for the engineering and construction services to address deficiencies identified in two selected reaches of the Redwood Creek in connection with the 2016 Redwood Creek Repair and Rehabilitation Project. The selected reaches are as follows: Jefferson Branch Reach 1 — Redwood Creek Jefferson Branch from Hudson Street to Madison Avenue (approximately 300 linear feet). Redwood Branch Reach 1 — Redwood Creek Redwood Branch from Broadway Street to Maple Street (approximately 1400 linear feet). The City is currently contracting with Wood Rodgers, Inc. for the engineering and construction services to address deficiencies identified in two selected reaches of the Redwood Creek in connection with the 2017 Redwood Creek Improvement Project. The selected reaches are as follows: Jefferson Branch Reach 2 — Redwood Creek Jefferson Branch from Clinton Street and EI Camino Real (approximately 1000 linear feet). Redwood Branch Reach 2 — Redwood Creek Redwood Branch from Hudson Street to Oak Street (approximately 1500 linear feet).
