Sawyer Camp Trail Closed Friday, November 2; Partial Trail Closure on Saturday November 3 & 10

Sawyer Camp Trail will be closed all day on Friday, November 2 and partially closed the next two Saturdays to complete vegetation restoration within the seasonal window imposed by environmental requirements.

This hydroseeding and replanting work requires heavy equipment and trucks on the trail.  The closures are necessary to ensure public safety. 

On Saturday November 3 and November 10, a one-mile middle section of the trail will be closed from approximately the 2.1 mile marker to the 3.2 mile marker. Both the northern and southern trailheads will remain open, but there will be no through-access.

The seismic upgrades to the water pipeline that runs adjacent to Sawyer Camp Trail were completed in early autumn. Brief trail closures will still be necessary through 2013 for restoration of the trail.

·         November 2 (Friday) – Entire trail closed

·         November 10 (Saturday) – Partial closure of middle one-mile segment

Partial Sawyer Camp Trail Closure on Saturday, October 27th

The middle section of Sawyer Camp Trail will be closed to the public on Saturday, October 27th. There will be no through-access on the trail the entire day, as crews work to complete a time-sensitive revegetation project that requires heavy trucks and machinery to block the trail’s middle segment.

The trail will remain open at the southern trailhead (located at Skyline and Crystal Springs Road) up to approximately the 2 mile marker. The northern trailhead (at Hillcrest Blvd.) will also remain open, to approximately the 3.1 mile marker. However, trail users will need to turn around at the closure point and exit the trail the same way they entered.

For your safety, please do not enter beyond the posted barricades! The one-mile middle section of the trail will be an active construction zone.

San Andreas Trail will remain open. Please see below for bicycle detour information.

The replanting that is underway on Sawyer Camp Trail is timed to coincide with the start of the rainy season, and must be precisely sequenced. Unexpectedly heavy rains earlier in the week postponed the completion of hydroseeding in some areas to this Saturday.

Hydroseeding will continue along Sawyer Camp Trail through mid-November. Our team will continue to keep the entire trail open whenever possible. Please subscribe (see right) for automatic email updates or call us 24 hours a day at (866) 973-1476.

·         Bicycles are allowed on Highway 280 between Hillcrest Blvd. and Black Mountain Road. (Bicycles are not allowed on 280 south of Black Mountain Road and must exit).

·         Cyclists who prefer surface streets to biking on 280 can detour around the Sawyer Camp Trail closure as follows:
(From northern trailhead of Sawyer Camp Trail at Hillcrest Blvd. to southern trailhead)
Proceed East on Hillcrest and take a right on Hwy 35
Left on Millbrae Ave.
(Next) Right on Vallejo Drive
Left on Frontera Way (when Vallejo Drive ends)
Right on Murchison Drive
Right (west) on Trousdale
Left (south) on Hwy 35
Right on Hayne Road (in Hillsborough) and continue under Hwy 280 to stay on Hwy 35
Proceed south on Hwy 35 to southern trailhead of Sawyer Camp Trail at Hwy 35 and Crystal Springs Rd.

Hydroseeding Begins on Sawyer Camp Trail - Trail to Remain Open

This Thursday and Friday, October 11th and 12th, our contractor will begin hydroseeding along Sawyer Camp Trail. This is the first step in the process to restore vegetation following the seismic upgrades to the water system. The trail will remain open during this work.

One hydroseed truck and two water trucks will be present from 7 a.m. to 5:30 p.m. between the southern trailhead and the 2.6 mile marker. The water trucks will refill a few times per day at fire hydrants located on the trail.

All vehicle traffic on the trail will follow the 5 mph speed limit. Cyclists and roller bladers should use caution and travel slowly through the southern half of the trail.

We expect hydroseeding to continue every Thursday and Friday for the next four weeks. Trail closures may be necessary to complete the work. Please subscribe to this site to receive automatic email updates (see box at right).

The project team is making every effort to keep the trail open during the popular fall season. Please let us know how we are doing by posting a comment on this site. We can also be reached at or (866) 973-1476.

Be Prepared!

The 23rd anniversary of the freeway-flattening Loma Prieta earthquake is coming up on October 17th. In the event of a similar emergency, will you be prepared? Will you have enough drinking water?

Make This October Emergency Preparedness Month!
The San Francisco Public Utilities Commission (SFPUC) operates the Hetch Hetchy Regional Water System, which provides high-quality drinking water to 2.6 million residents and businesses across four Bay Area counties. The SFPUC is making the investment to seismically upgrade regional water facilities, tunnels, and pipelines. However, it is important for you to remember that smaller pipelines leading to your home might be damaged in an earthquake. As a result, water from your tap may be unavailable for up to 72 hours or longer.

To prepare for an emergency:

Keep a 3-day water supply just in case!
• Each family member needs 1 gallon per day
• Store tap water in food-grade plastic containers; replace every 6 months
• Store bottled water in the original sealed containers; replace according to expiration date.


If your supply runs out, you can treat your water!
• Boil it for 3 minutes, or disinfect it by adding regular household bleach
• Add 8 drops of bleach per gallon of water
• Shake or stir then let it stand for 30 minutes
