The Challenge

The City of Santa Cruz needed to protect its water supply system by addressing deficiencies in the inlet/outlet works to maintain full system functionality and reliability, as well as meet state requirements for emergency drawdowns. The City faced engineering challenges given the complex details of design and construction challenges due to the limited windows in which to complete initial stages of the project located in the creek and spillway.
