Title

Woodcreek Oaks Boulevard Widening Project

Description

CDFW has executed Lake and Streambed Alteration Agreement No. 1600-2017-0005-R2, pursuant to section 1602 of the Fish and Game Code to the project Applicant, City of Roseville (Permittee) as represented by Stefanie Kemen. Project is limited to the construction of a new bridge adjacent to the existing bridge along Woodcreek Oaks Boulevard over South Branch Pleasant Grove Creek as part of the Woodcreek Oaks Boulevard Widening Project. The new bridge will be approx. 130 feet long and 50 feet wide and will parallel the existing bridge with an approx. 6-foot gap separating the bridges. The existing bridge will be restriped to carry the southbound lanes and the new bridge will carry the northbound lanes. Both the new and existing bridge widths will provide sufficient width to carry bridge railings at each edge of deck, a sidewalk or a multi-use path, two shoulders/bike lanes and two vehicle travel lanes. The new bridge deck will consist of a reinforced concrete slab, supported by two linear set of extension piers and reinforced concrete abutments supported on a pile foundation. The new bridge and roadway profile would be elevated to provide the necessary freeboard over the 100-year flood event water surface elevation for South Branch Pleasant Grove Creek. Additionally, the proposed bridge will be a three-span, cast-in-place, reinforced concrete-slab bridge. Equipment access routes will be cleared and graded; however, these cleared sites will be treated with erosion control and revegetated following construction. If the creek is still flowing during construction, any flowing water will be piped through the construction site using a coffer dam upstream and downstream of the project to direct water into culvert pipes. The piling for the pile extension piers and abutments will be installed adjacent to South Branch Pleasant Grove Creek. The pile extension piers will be installed using an impact pile driver. Falsework will be installed to provide support for placing the concrete bridge deck. The bridge deck formwork and reinforcing steel will be placed and the concrete will be cast. The roadway embankment and slopes will be placed and compacted behind and adjacent to the bridge abutments. The concrete bridge railing and sidewalks will be placed and the approach roadway will be paved and striped.
