Pretty easy process. The exception is City of Davis had 3 different services to mark, sewer, H²O & electical. 2 were done right away. 1 was done days after project was suppose to start. PG&E, Comcast, & ATT all responded in the time frame requested by call 811 before you dig.

First-time caller. I'm doing some landscaping and backyard work. They helped explain the process and how my contractor should call in at least 2 days prior to work. Appreciate the information to keep me and those working at my property safe. Local utilities came and marked the underground facilities.
