Woodside: Gas main repaired and Sand Hill Road to reopen this afternoon, PG&E says


A crew from Pacific Gas & Electric is expected to have completed repairs associated with a leaking valve in a three-inch gas main in the 3900 block of Sand Hill Road by this afternoon (May 6), PG&E says. The leak itself has been repaired and the crew is filling in the hole along the side of the road, a company spokesperson said.

In the meantime, drivers and cyclists should use Manzanita Way, Winding Way, Mountain Home and Portola roads as a route around the work site, said Sean Rose, public works director for the town of Woodside.

The section of pipeline taken out of service to repair the leak will remain out of service for the foreseeable future while PG&E considers further repairs, PG&E spokeswoman Melissa Subbotin said. The repairs may include relocating the pipe so that it's not 11 feet underground and "wouldn't require the level of excavation that this specific project required," Ms. Subbotin said.

The depth of the hole required crews to install shoring to prevent the earthen walls from collapsing, which led to the decision to close the road, Ms. Subbotin had said earlier.

"The leak has been addressed and remediated," she said Friday morning (May 6). "There was no danger to the public or the crews. That's our number one priority."

The leak occurred in an area not in the immediate vicinity of gas customers, Ms. Subbotin said. Customers served by that main had their gas supply rerouted as soon as the leak was discovered, with no interruption of service, she said.

PG&E uses Picarro leak-detection technology. The technology is mounted on a vehicle and can sense leaks at driving speeds, according the website PG&E crews also perform leak-detection surveys on foot.

The dunderhead who decided to route the detour down Manzanita Way and Winding Way in Woodside should lose their job for the dangerous road hazard they have created. Neither road is capable of handling the volume of traffic from Sand Hill and now has vehicles speeding far in excess of the (25 mph) speed limit through narrow residential streets with limit passing space and often no shoulders.

Thoughtless and dangerous!

Agreed that Manzanita and Winding are not appropriate for lots of traffic, but are there any other options given which piece of the road was closed? I don't live right there, but nearby enough that I've driven and cycled on both of those roads a lot and I can't think of any parallel alternatives short of closing Sand Hill back at 280 and forcing everyone onto Alpine to go to either Woodside Road or Alpine.

There are other options that should have been used such as:

- Whiskey Hill Road to Woodside Road
- Woodside Road to Portola Road

Traffic control by the Sheriff at the 4-way stop in the center of Woodside could have been used to mitigate the inevitable backups.

Better communication could have provided folks with the alternative of using Alpine Road to access Portola Valley.

Agreed! I live in this area and I couldn't believe their suggested route. As mentioned earlier Whiskey Hill or Woodside Road exit off 280 much smarter. Also, cars coming down the 84 hill should be diverted down Woodside Road rather than trying to get to Sand Hill through Portola only to be routed back to Mt. Home.

Not sure what they were thinking.
