those improvements (including the relocation of the Alameda County Flood Control and Water Conservation Districts B-2 Channel). Consulting services, including specialty inspections, are required as part of this construction work. The subject consulting services consist of engineering shop drawing review and construction inspection services for the Railroad bridge structure including temporary shoring, the storm drain pump station and the storm drain box culvert. S & C Engineers has proposed to provide these services at a cost not to exceed $77,170.00. Funding for these services will be provided under terms of a reimbursement agreement with the developer, Bernal Investment Company (BIC). Honorable Mayor and Members of the City Council: BACKGROUND The project includes the extension of Valley Avenue from Laguna Creek Lane to the intersection of Junipero Street/Case Avenue crossing the Union Pacific Railroad tracks via a new undercrossing. The street section will allow for one lane in each direction, plus a 6 foot wide disabled vehicle area on both sides of the street and a separated bike/pedestrian walkway. The undercrossing will be similar to the Bernal Avenue undercrossing, but with fewer lanes. A traffic signal will be installed at the street intersection of Junipero Street/Case Avenue. Additionally, east of this intersection, Junipero Street will be widened along the Zone 7 flood control channel to allow for a left turn lane at Case Avenue into the new KB Home subdivision, Canyon Oaks. On the other side of the railroad undercrossing, the street intersects with Laguna Creek Lane where there is an existing traffic roundabout. In addition to the street extension, the project also involves the rerouting of the Zone 7's B-2 channel around the undercrossing, including the installation of a concrete box culvert where the channel crosses under Valley Avenue. The Zone 7 channel will be reconstructed as a meandering stream consistent with the City's channel restoration plans for the Berual Property. The City commonly enters into separate consultant contracts to provide engineering shop drawing review and inspection services during the construction of bridges, concrete box culverts and pump stations, as the City does not staff specialists in these areas. Thus, it is recommended that an engineering consultant be retained to assist staff in assuring conformance with the approved plans and specifications for this work. SR:05:209 Page 2 of 10
