7th Avenue Water Main Replacement Project, October 2019 The City has hired JK Woods Construction, Inc. to replace the 8" diameter water main in 7th Avenue between East Cliff Drive and the rail road tracks. The water main has had a number of disruptive breaks recently, making its replacement urgent. Work is expected to be completed in February 2020, depending on winter weather conditions. You can view the project map and public notice here.

Newell Creek Access Road Bridge, September 2019 Construction will occur during the months of September and October at the intersections of the bridge, Newell Creek Road, and private driveways serving addresses 10212, 10206, 10218, 10220. The construction work area will be in the creek below the bridge. The contractor will not block vehicle access across the bridge.

September 5: The contractor has laid approximately 1/4 mile of new 12' water main, and approximately 110 linear feet of 16" water main across the May Ave & Water St intersection. Pipe has been installed from Market St to the Ocean & Water St intersection, and from the east side of the San Lorenzo bridge to the Starbucks at the Ocean & Water St intersection.

University Tank No. 5 (U5), April 2, 2019

Work Completed: Demolition was completed between 2/18/19 and 2/26/19 using a hydraulic shear excavator. March rains have slightly delayed the project but it is still on schedule and the contractor is doing their best to manage the rainwater onsite (stormwater management, dewatering pumps, etc.)

Piping installation and foundation prepartions should continue through the end of April before tank erection begins in early May.

A picture of the demolition operation is below:


U5 is a two-million gallon steel water storage tank that was constructed in 1959. Located off of Empire Grade, U5 is one of three water storage tanks labeled "University," which, despite the name, serves the west side of Santa Cruz and the north coast, in addition to the university. Significant corrosion, a number of compromised structural members, the inability to meet current building code design standards, and other factors require replacement of the tank.

The U5 tank replacement project includes three phases:

  1. Installation of a 35,000 gallon temporary tank to provide water while U5 is out of service. Completed in April 2018.
  2. Replacement of the inlet/outlet pipeline (about 900 feet of water main serving the tank off of Empire Grade.) Under construction August 2018 - December 2018.
  3. Demolition and reconstruction of a new U5 tank. Under construction December 2018 - October 2019.

Felton Diversion Inflatable Dam Rubber Bladder Replacement Project
The City of Santa Cruz operates an 8’ high by 75’ wide inflatable diversion dam on the San Lorenzo River that is raised during high river flow periods between September 1 and May 1 of each year. The impounded water is then pumped to storage at the City’s Loch Lomond Reservoir. Water drawn from the reservoir is treated to drinking water standards at the Graham Hill Water Treatment Plant, and distributed to the city’s water service area. During the summer months and other low flow periods the dam is deflated to allow river flows to pass the facility. 

The Felton Diversion facility was constructed in 1974. The current Bridgestone rubber bladder was installed in 1985 and will be replaced during this project. The work includes diverting the San Lorenzo River through the diversion facility’s bypass sluiceway and around the construction area, removing and properly disposing of the existing rubber bladder, installing the new rubber bladder, and returning the river path to its pre-construction condition. 

The project began on September 10 and is expected to be completed in approximately two months. To see the neighborhood notification letter and photos of the project, please click here.

River Street Water Main Replacement, overall construction activities July 2017 - September 2018: The water main under River Street is almost a century old. The Water Department needs to replace it. We have contracted with Anderson Pacific Engineering Construction Inc. to install approximately 1,000 feet of 18" pipe, 1,600 feet of 12" pipe, 13 pipeline connections, and 37 water service reconnections on River Street; and 1,110 feet of 8" pipe, 3 pipeline connections, 100 feet of slip-lining, 16 water service reconnections, and 3 water service renewals on Potrero Street.

Overall construction activities will take place from July 2017 through September 2018, excluding weekends and holidays. While every attempt will be made to keep the construciton disturbance to a minimum, you may experience traffic delays, restricted street parking, and increased noise during working hours. There may also be short scheduled periods of no water service. The contractor and the City will make every effort to provide 72 hours advance notice of any non-emergency water service interruptions that may be necessitated by the construction.

Bay Street Tanks Landscaping, mid-July through October 2017: The final phase of the Bay Street Tanks project will conclude in 2017 with project site landscaping. The project includes regrading the frontage, upgrading the fencing, and planting native and drought tolerant trees and shrubs. The neighborhood closest to the site can expect typical construction noise on weekdays between the hours of 8:00am and 5:00pm. We apologize that the sidewalk on Cardiff Place along the frontage willl be closed and pedstrians will be re-routed to the sidewalk on the other side of the street during construction. Some parking may be restricted on Cardiff Place as well.

North Coast Main Replacement, Phase 3: The fourth and final shutdown for tie-ins started last Monday 6/12 and has progressed smoothly. The project area is particularly challenging; in one area 80' of existing steel pipe was removed, with a new pipe installed underneath the existing Coast potable water main and landfill leachate line. Phase 3 is expected to be complete by the end of June.


Bay Street Solar PV Project: Sandbar Solar designed and is installing a 298kW (DC) solar PV system on the roof of one of the new 6-million gallon concrete water tanks at Bay Street. This solar PV system will offset the power used at the tank site, as well as the nearby University 2 pump station. Construction began in May and is expected to be complete by July 21, 2017.

Tait Wells Replacement and Rehabilitation Project, beginning April: Anderson Pacific Engineering Construction, Inc. completed construction of a new well motor control center, two new replacement well pump stations, and site improvements in January 2017 near 200 Crossing Strteet. This project expands the availability and reliability of source water, water treatment opterational flexibility, and water quality. Tait Wells played a crucial role as a reliable high quality water source during the recent winter storms in January and February 2017.
