Solicitation

This solicitation outlines the "Alameda Zone 7 Flood Control Channels, PL 84-99 Repairs, Phase 2 and Phase 3" project. The project aims to repair storm damage to flood control channels in Alameda County, California, caused by erosion and bank failures during atmospheric rivers in late 2022 and early 2023. The work involves repairing 46 damaged sites across seven flood control channels.

• Phase 2 (21 sites): Repairs at Arroyo de la Laguna, Arroyo del Valle, Alamo Canal, Arroyo Mocho, and Tassajara Creek.

• Phase 3 (20 sites): Repairs at South San Ramon Creek, Alamo Canal, and Alamo Creek.

• Repair Methods:

  • Toe Erosion Repair (16 sites): Installation of 1½-ton rock riprap armoring on the lower 1/4 to 1/3 of the slope face, keyed into the toe of the slope, separated by a gravel filter layer. The area between the 2- and 10-year flow elevations will be backfilled with soil and covered with 0.5 ft of compacted native soil, then hydroseeded.
  • Full Bank Repair (19 sites): Excavation of damaged areas, placement of 1½-ton rock riprap armoring from the toe of the slope to the 10-year water surface elevation, keyed into the toe and separated by a gravel filter layer.

This will be backfilled with soil and covered with a 0.5-foot-thick layer of compacted native soil, then hydroseeded.

• Environmental Controls: Strict adherence to environmental protection measures, including work windows (June 15 - October 15 for in-water work, with potential extensions), protection of special-status species (California red-legged frog, Central California Coast steelhead), erosion and sediment control, stormwater management, and waste management.
