Updated on April 17, 2017

Pre-construction activities begin in April

In late April or early May, prior to the start of construction, the contractor will take photographs of existing conditions along public streets and water district property.

Starting on April 24, there will be closures of the pedestrian bridge at Belshaw Drive and Paseo Refugio, and the levee on the south bank of the creek along Sutterwind Drive. The bridge and levee will be temporarily closed for public use while the contractor moves materials on site and begins work to remove, raise and replace the bridge by December 2018.

The contractor will move equipment and materials to the site and install temporary shoring at the water district's right of way line. The shoring work includes installing temporary metal plates in the ground to secure the dirt during construction.

We will continue to share new information on the website and with the email subscriber list.

The Santa Clara Valley Water District is currently constructing flood protection improvements along Lower Berryessa Creek in Milpitas, between Abel Street and Calaveras Boulevard, known as Phase 2. This year is the second of three construction seasons for Phase 2. Work activities within the creek channel will begin in May 2017 and continue through October 2017. Work outside the creek channel will continue from November 2017 through May 2018.

The following activities are planned for the 2017 construction season:

  • Removing approximately 140 feet of the soundwall adjacent to the railroad tracks near Edgewater Drive.
  • Installing foundation piles for the concrete floodwall along the south side of the creek between N. Milpitas Boulevard and Calaveras Boulevard.
  • Installing foundation piles and building concrete floodwalls along the south side of the creek adjacent to the future BART tracks near Abel Street.
  • Raising the pedestrian bridge at Belshaw Drive and Paseo Refugio. In order to raise the bridge abutment, the pedestrian bridge will be temporarily removed beginning in May 2017 and then replaced by December 2018.

Construction work and schedule are subject to change. If there are any changes, we will provide an update of the work and schedule.

What to expect during construction:

  • In late April or early May, prior to the start of construction, the contractor will take photographs of existing conditions along public streets and water district property.
  • Regular work hours are 7 a.m. to 7 p.m., Monday through Friday, and 8 a.m. to 5 p.m. on Saturday.
  • Sunday work hours are 9 a.m. to 4 p.m. and is limited to the area adjacent to the future BART tracks. Sunday work will end on October 15.
  • Truck hauling will occur between 9 a.m. and 4 p.m. to accommodate peak traffic hours.
  • Majority of the construction work will be conducted in and along the creek, within the water district's right of way.
  • Expect typical construction noise during work hours from heavy equipment, such as drilling rigs, shoring installation rigs, excavators, concrete trucks, and hauling trucks.
  • A water truck will spray the work area to control any dust from construction activities.
  • Temporary lane closures along N. Milpitas Boulevard for trucks and crews to access the creek. Two-way traffic will be maintained, but may be reduced to one lane in each direction. Flaggers may be used for traffic control.
  • Generators may be used to pump water around the project site and back into the creek further downstream.
  • A visual screening fence will be installed around the work areas for community safety, site security and to control dust. Only construction personnel are authorized on site.

Vibration monitoring reports
Devices have been installed along the project work areas to monitor any vibrations caused by the construction activities. The construction activities are required to stay below the vibration limit of 0.2 inches per second.
