Traffic/Trail Impacts

Traffic Impact graphicFrom 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.


  • The U.S. Army Corps of Engineers and the water district will temporarily close South Milpitas Boulevard from the intersection of Montague Expressway north to Garden Street from Monday, Oct. 2 at 11 a.m. to Tuesday, Oct. 10 at 5 a.m.

    The closure is needed to replace an existing Union Pacific Railroad Bridge with a new box culvert about 5,000 feet north of Montague Expressway and the existing railroad tracks at the South Milpitas Boulevard crossing and at the new bridge.

  • Adobe Creek Loop Trail temporarily closed due to Palo Alto Flood Basin tide gate structure repair activities

    The Santa Clara Valley Water District is repairing structural damage to the Palo Alto Flood Basin tide gate caused by the effects of aging. The work consists of dewatering the tide gate structure, repairing the concrete surface of the deck and the intermediate and end walls below the deck of the structure, and replacing the chain link railing on the structure deck.

    Due to the removal of the chain link railing and the repairs needed on the deck of the structure, the trail will need to be closed in both directions for public safety.

    We urge residents and trail users to watch for trail detour signs and take caution when using the trail, especially during heavy storm events.

  • Stevens Creek Trail temporarily closed due to bank erosion and emergency repair work
    The Santa Clara Valley Water District is conducting emergency erosion repair at Stevens Creek in Mountain View to shore up a bank weakened by January and February storms. The work is necessary to prevent further erosion of the maintenance access road and protect the structural integrity of a temporary trail and redwood trees in the vicinity.

    In August, the bank endured soil loss that created a gap in the water district's maintenance access road, a pathway already closed due to erosion caused by this year's winter storms. Further study revealed that erosion continues to grow in width and length and is now about five- to six-feet away from the trail and redwood trees.

    Over the next 50 days from 7:30 a.m. to 5 p.m., Monday through Friday, a five-person crew will work along the east bank of Stevens Creek, approximately 700-feet north of El Camino Real. Depending on the progression of the work, the water district may need to also work on Saturdays between 8 a.m. and 5 p.m. to complete the work within the 50 days.

    Please report downed trees in creeks or other creek blockages to the water district's watershed hotline at (408)630-2378 or use the Access Valley Water online reporting system at

    For any questions or concerns, contact Keiron Nawbatt at (408)630-2896.

Fuel Abatement and Fire Suppression Work
The Santa Clara Valley Water District is conducting annual fuel abatement and fire suppression work along stream channels, levees and other areas it oversees. The work includes mowing existing vegetation to ensure compliance with the Santa Clara County Fire Marshal.

As some of the work requires access to public trails, trails will be closed for short periods of time for public safety. The water district coordinates with the appropriate municipalities through joint use agreements to ensure those jurisdictions know of the planned work.

Dates and times shown below are subject to change.

  • No trails currently closed           

For more information on trail closures, fuel abatement and fire suppression work, please contact Terri Gross at 408-630-3871.
