Locating Utilities Before You Dig

If you are planning to excavate on your property, you are required by law to notify the Underground Service Alert network at least 2 working days prior to digging to locate utilities such as electric, water, telephone, or natural gas lines. Underground Service Alert will send a field representative to check your excavation plans against maps of underground utilities and other potential hazards. Failure to contact Underground Service Alert may result in damage to utilities, with potential danger of severe property damage, injury, and even death. Once the Underground Service Alert network signs off on your excavation plans, you are relieved of all financial liability for any mapping or inspection errors that might occur. Refer to Digging Underground (a PDF file) for more information about locating utilities.

To obtain an Underground Service Alert inspection, call 1-800-227-2600.

For more information, contact Alameda Power & Telecom between 8:00 AM and 5:00 PM, Monday through Friday at 510-748-3900.
