Why is PG&E doing construction in Palo Alto? CPAU 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.
