- Voters have approved three half-cent sales taxes to be extended through 2084 to cover the local share.
The Diversion Authority continues to look for efficiencies and is planning to hold an additional “Value Engineering” workshop to explore where there may be cost-saving opportunities. Cost saving opportunities could involve tweaking preliminary designs of certain project features, while still maintaining the overall functionality of the federally authorized Project.
A Split Delivery model would deliver the majority of the Diversion Project’s features through a Public-Private Partnership (P3) project, while the U.S. Army Corps of Engineers intends to use traditional design-bid-build method. The P3 model will deliver the best value for the public’s money, provide performance guarantees and long-term warranties that otherwise would not be available, promote delivery innovation, and shorten the schedule to achieve flood risk reduction sooner than could be achieved otherwise.
