Traffic and Trail Impacts

Content

From time to time our construction and maintenance projects require temporary road or lane closures, trail closures or similar impacts to vehicular or pedestrian traffic. Current and planned impacts will be noticed here.

Current Trail Impacts

Permanente Creek Temporary Trail Detours (January 2023)

The Permanente Creek Floodwall Retrofit Project involves retrofitting the foundations of approximately 1,300 feet of floodwalls along the eastern bank of Permanente Creek between Charleston Rd. and US Highway 101 in Mountain View. The foundations will be reinforced and widened to increase the floodwall's stability. The retrofit work starts in late January 2023 and continues through May 2023. Trail detours begin January 30, 2023.

As shown in this map, there will be two temporary trail detours. The first detour, defined by the blue-striped path, will last five days as crews build a temporary pedestrian ramp to separate trail users from the construction area. The same detour is expected to be implemented again after the project is completed to accommodate the removal of the temporary ramp and restoration of the trail to its original condition. The second trail detour, defined by the green dotted path, will start after the temporary pedestrian ramp is constructed and will be in effect through the project's completion, anticipated in May 2023.

Lower Penitencia Creek Improvements Project (spring 2023)

Valley Water’s contractor is working to provide continued flood protection for residents and businesses located along the one-mile project length from Milmont Drive downstream to I-880 in Milpitas.

The two sections of trails, San Andreas Dr. to Milmont Dr. and Milmont Dr. to California Cir., are temporarily closed. The trail was dug up to accommodate pipe installation and other project tasks. In its current state, the trail is unsafe and in no condition for walking. Without further rain delays, the anticipated start of the grading and resurfacing of the trail between San Andreas Dr. and Milmont Dr. is late Feb 2023. The section from Milmont Dr. to California Cir will start in early March 2023. The trail will reopen once the grading and resurfacing work is done.

Our goal is to complete the project safely and quickly by spring 2023. Visit the Lower Penitencia Creek Improvements Project to learn more about the project.

Stream Maintenance Program (to be updated in June 2023)

As part of our Stream Maintenance Program (SMP), Valley Water performs work along creeks across Santa Clara County every summer. Under the SMP, work occurs annually to improve the environment, reduce flooding risk, and keep our communities safe. For decades, our crews have been trekking into streams to remove sediment build-up, manage vegetation, clear trash and debris, and stabilize banks that have eroded during high water flows. For the public's safety, work crews and to complete this vital community work, on occasion trails will be temporarily closed. The following is a list of the impacted trails:

Current Traffic Impacts

Valley Water is constructing the South County Recycled Water Pipeline Project to enhance Gilroy’s recycled water distribution system. Once completed, the distribution of additional recycled water will expand service to existing customers, improve delivery, allow service to new customers, and support future system expansion. We thank you for your patience while we are under construction.

Traffic impacts are to be posted as they are scheduled. 

To help reduce noise overnight, crews will engage in heavier work at the beginning of the evening.
