Underground and Overhead Construction
SCE is rebuilding electric infrastructure across Altadena using underground and overhead construction based on the needs and conditions of each project area. The approach may vary based on engineering, safety, permitting, field conditions, constructability, timing and other project requirements.
Rebuild Underground Power Lines
- Select electrical equipment will be placed underground.
- Work may include trenching, installing conduit and vaults, inspections and connecting customers to the new system.
- Customers may see survey crews, road work, traffic controls, construction equipment and staged restoration.
- Individual service work may continue after community infrastructure is complete.
Rebuild Overhead Power Lines
- Electrical facilities are rebuilt or replaced overhead where appropriate.
- Work may involve power poles, electrical lines, equipment and service connections.
- Some existing overhead facilities may remain.
- Telephone, internet or other companies’ facilities may also remain overhead.

| Planning | During this phase, SCE planners and surveyors will assess the area to help define the work planned for the community. This work may include accessing electrical equipment, as well as taking photos of the equipment and nearby areas. During design, planners first look for routes within public rights-of-way. |
|---|---|
| Permitting | Once the scope of work is created, SCE will determine the necessary permit needs. Most projects require at least one road closure permit from the county. Permit approval may take as little as two months but could take significantly longer depending on individual project settings. In some cases, SCE will need a Right of Entry agreement for limited access to private property to install new equipment. |
| Construction | Construction can begin after SCE receives all required permits and land rights. Crews may survey the area, mark underground utilities and prepare streets or work zones before installing the new underground equipment. During construction, you may see large equipment, temporary traffic changes, lane closures or limited road access. Crews will repair affected areas and remove materials and equipment when the underground work is complete. Completing construction brings the project area one step closer to long-term recovery and improved resilience. |
| Completed | SCE completes final inspections and related work so the underground electrical equipment can be placed into service and the project area can move closer to long-term recovery and improved resilience. |
| Existing Equipment | Overhead or undergrounded powerlines currently in place. |
