Urban Levee Design Criteria 200 Yr
Several portions of the levees were identified in 2013 as needing additional work in order to meet the new Senate Bill 5 requirements for urban levee design criteria (ULDC). This additional 200 Yr ULDC work was added to Phase 4 and the UYLIP EIP funding agreement. The Figure 4 map shows the locations of the work completed.

Another area, was located along the Feather River Segment 1 section of levee, this work was completed in 2014.
The third area of work was on the Western Pacific Interceptor Canal (WPIC) and this project was completed in 2019.
