Title

Tudor Flood Risk Reduction Project

Description

Planned levee remedial measures for the Project include construction of a cutoff wall, a berm tie-in to the HWY 99 embankment, pipe penetration improvements, and surficial geometry corrections. Improvement measures were developed based on the 100-year design water surface elevation (DWSE) provided in Design Water Surface Profiles for the Feather River West Levee Project, Addendum #2, dated December 2013 and prepared by Peterson Brustad, Inc. Fill material for the levee and clay core would be obtained from either an off-site borrow source(s) or from excess material obtained from Project excavations. The construction contractor will be required to obtain off-site borrow materials, which may be imported to the Project Area from local sources or existing permitted commercial sources. Borrow sources for earthen materials are anticipated to be in the vicinity of Sutter and Yuba Counties. Other materials, such as aggregate base, bentonite for the cutoff wall, pipe, concrete products, and materials needed to support construction, would be obtained from off-site commercial vendors and sources. The Project incorporates construction areas along the land and water sides of the levee. These areas would be utilized by the contractor for access, hauling, spoiling of material, storage, fueling, and other construction related activities. Prior to and during construction of remedial measures, staging areas would be established to allow for efficient use and distribution of materials and equipment. Staging areas would be identified by the contractor during construction and would be located within the Project Area limits.
