Document Description
The project would involve construction of improvements along the Taylor Slough levee between stations 0+00 and 130+00 (site 1), and seepage reduction improvements along the Sand Mound Slough levee between levee stations 340+00 and 450+00 (site 2). Site 1 levees would be improved to meet Bulletin 192-82 criteria, including raising and widening the levee crest, waterside slope armoring, landside slope flattening, installation of a levee crown all-weather road, and geotechnical remediation. Site 1 would also include habitat creation along 8,000 lf of the land and waterside of the levee. Site 2 may include drainage blanket and ditch construction, monitoring well installation, and subsurface drainage enhancements to address ongoing seepage issues along Windsweep and Stone Roads. The project would take approx 2 years to construct.
