Site work for a water / sewer project in Simi Valley, California. Conceptual plans call for site work for a water / sewer project.

This project would upgrade the piping and mitigate seismic deficiencies for the 426,000 gallon capacity Stearns Tank No. 1 that has been in service since 1960. The Waterworks Facilities Assessment conducted by Carollo Engineers in 2015 recommended revising the site layout, realigning the piping, and/or a combination of each to install a flexible pipe connection with a full range of differential movement. In addition, the Seismic Evaluation of the Waterworks Storage Tank System conducted by Kenney Jenks in 2020 identified that the during a seismic event that the tank would be unstable and needs fo be anchored to a ring wall foundation and to prevent damage to the roof and shell the tank roof needs to be raised by 5 feet to increase freeboard. Based on the age of the tank and the anticipated costs of the recommended seismic improvements, staff recommends to replace the tank rather than to retrofit. The Design is expected to be completed in November 2022 and construction is expected to be completed by June 2023. Project is included in the City of Simi Valley's FY 2022 - 2027 CIP. As of June 22, 2022, information regarding a design team and a general contractor is not available. Design is anticipated to be completed in November 2022 and construction is anticipated to be completed by June 2023.* *Project information has been obtained through a public capital improvement plan (CIP).
