6.1.B. - Page 1 To the Honorable Mayor and City Cou nci I From the City Manager January 23, 2012 SUBJECT Design Services Agreement with BKF Engineers for the Redwood Creek Box Culvert Relocation Project (Middlefield Road) RECOMMENDATION Approve, by motion, the standard form design services agreement with BKF Engineers of Redwood City for an amount not to exceed $158,928.00 and authorize the City Manager to increase the contract amount up to 10%, if necessary. BAC KG RO U N D Redwood Creek and its tributaries collectively comprise about 8 miles of waterway and traverse across much of Redwood City, from the hillside to downtown and to the Bay. The lower Jefferson Branch of the creek, which flows from the railroad tracks, converges with the main branch of Redwood Creek just before reaching Broadway, was a natural open creek that meandered through most of downtown Redwood City. In the 1950s, the lower Jefferson Branch section, as well as most reaches in downtown, was enclosed in concrete culverts to allow for better usage of the land and to improve drainage. ANALYSIS A particular section of the lower Jefferson Branch, an approximately 400-foot long, 15- foot wide, 7.5-foot deep concrete box culvert, bisects the parcel of land, 950 Middlefield Road (APN 052-363-120), owned by Redwood City. (See attached Site Map.) Based on City Council direction, staff is exploring options for relocating and/or "day lighting" the creek. The overall goal is to relocate the box culvert off the parcel and in the public right-of-way on Middlefield Road to avoid the possibility of having the culvert in easement should the parcel change ownership. If approved, once designed, the culvert relocation will be part of the city's Capital Improvement Program, under the Storm Drain Creeks & Channel sub-program. The consultant's Agreement anticipates completion of the design phase by the end of April 2012, which enables the City to bid during the spring for construction during 2012. After a consultant review process, the consultant, BKF Engineers, has been selected by staff for its familiarity with the Redwood Creek system and its expertise with similar
