The plates on the streets are placed/owned and maintained by the Utilities, Contractors working for the Utilities, and third-party developers.

|Location:||To allow us to complete some of this work, we might need to shut off power at times. If and when we do need to shut off power, all impacted customers will receive direct notices of the power shut-down(s) at least three or more days before the event.|
|Rebuild Underground District 24|
|Project Overview:||Rebuild the underground electric system by replacing old equipment with new and reconfiguring it to current design standards. This is to ensure electric service reliability.|
|Duration:||Initial work on the project started October 2015. Because of the area and customers impacted by this work, staff has been working with customers on the scope of work and scheduling to minimize the impact. Work is performed after hours to minimize impact to businesses. Customers are notified in advance of any power shut offs necessary to perform the work. This has delayed completion, now expected to be finished by summer of 2017.|
|Location:||Area bounded by Lytton Ave, Bryant Street, Forest Avenue, and Alma road, as well as smaller areas downtown near Cowper Street and University Avenue.|

Frequently Asked Questions
Why is PG&E doing construction in Palo Alto? The City of Palo Alto Utilities supplies natural gas to all residents and businesses in Palo Alto. However, the natural gas used in Palo Alto is transported to the City's distribution system through large transmission lines owned by PG&E. Here is a list of all current PG&E projects happening in Palo Alto.
What do the colored markings in the street mean? These different colored lines and letters have been placed to indicate the location of various underground utilities, so construction crews will not hit them while excavating. They are placed by Underground Services Alert (USA), the folks you should call (811) ANYTIME you plan to dig on your property. Here is a chart explaining what all the colors mean.
Why are Utilities crews digging up a street that was just repaved? This only happens when there is an urgent problem that must be addressed immediately. Otherwise, a 5 year moratorium on planned projects is observed after a street has been repaved.
