BACKGROUND
$48.3 million was appropriated in the U.S. Army Corps of Engineers (USACE) budget for Federal Fiscal Year 2021 in the USACE annual Work Plan for the Napa River/Napa Creek Flood Protection Project (Flood Project) to complete the federal responsibilities on the Floodwalls North of the Bypass Project (Increment 2) and the Imola to Hatt Floodwalls Project (Increment 3). These two projects are the remaining elements of the Project that were found to have Federal interest according to the Federal Interest Determination that was produced by USACE in 2020. Staff members have been working with the USACE since 2021 on a process to move forward to use the appropriated funds to complete these two elements.
This amendment increases the maximum compensation of the District's contract with HDR Engineering, Inc. by $292,054 to a new total of $18,138,826 for tasks related to the Floodwalls North of the Bypass Project construction (Increment 2). The following tasks for this project are included in the scope:
1. Additional support from the engineering team during construction.
2. Additional biological monitoring during construction.
3. Cultural monitoring during construction to fulfill the District's agreement with local Native American tribes.
4. Project renderings to support the District's remaining land acquisition actions on Increment 2.
