SCE is working to further reduce the risk of wildfire by burying power lines in high fire risk areas, especially where lines have not been replaced by covered conductor. SCE targets areas for undergrounding its power lines based on several considerations. The targeted undergrounding effort will make the electrical system more reliable during extreme weather conditions by protecting it from high winds, vegetation and other hazards that could cause fires or power outages.
Note: For undergrounding projects not related to wildfire mitigation, refer to Rule 20 undergrounding projects, which are initiated by a governmental agency (e.g., city, county), developer or individual customer.
Undergrounding Work Phases
Planning
During this phase, SCE planners and surveyors will conduct a feasibility assessment to help determine the scope of work that will take place in a selected community. They will gather data and make observations to analyze the viability of undergrounding electrical lines, which may include accessing and taking images of equipment and surrounding areas. This is a critical assessment to determine if this type of work can be completed at the proposed location.1 During the design phase, planners prioritize routes within public rights of way, but in some cases, limited access through private property (easements) may be needed.
Moving forward requires cooperation with property owners. Impacted property owners shall be informed about the upcoming project.
Permitting
Once the scope of work is established, SCE can determine if permitting is required. Most projects require at least one permit for road closures, typically from a city, county or Caltrans. Additional permit requirements depend on the project’s location. They may include state and federal land use permits, environmental clearances, or railroad rights-of-way permits. Permit approval may take as little as two months but could take significantly longer depending on individual project circumstances.
Construction
Work can be scheduled and construction can begin once all the required permits and necessary land rights are received.2 In most cases, this work will require a power outage at the end of construction, when the power is ready to be switched from the overhead to the underground lines. We will notify customers in advance if an outage is needed.

Frequently Asked Questions
FAQ
電線が地中化されていない場合、SCEは、裸電線を被覆導体に交換するなど、他の緩和策を追求し続けます。これは、特に検査や植生管理を行うことで補完される場合に、発火リスクを費用対効果よく迅速に低減する目的において最も価値のある手法の1つです。SCEの山火事緩和の取り組みの詳細については、sce.com/mitigationをご覧ください。
現在、山火事緩和を目的とした特定の地中化プロジェクトへの資金提供は、SCEの一般料金審査手続の一環として要請されています。これは政府機関（例：市、郡）、開発者、または個人の顧客によって開始されるルール20に基づく地中化プロジェクトとは異なります。
- Per current CPUC-approved tariff rules, customers are responsible for the cost of undergrounding service lines, which connect utility facilities to property owners’ electrical panels. These civil construction costs are typically paid to a private, licensed contractor hired by the homeowner to perform the civil work required to install an underground service line on the homeowner’s property. SCE is seeking alternative ways to help reduce this expense for these homeowners.
- At this point, there is an option for standing homes to remain with overhead service line connections with covered conductor.

1 An assessment is only to determine the feasibility of undergrounding power lines in the areas identified. It is not guaranteed that SCE will perform this work in your community.
2 Work may be rescheduled or delayed for various reasons, including crews' need to focus on emergency repairs, outage restrictions during heat storms and the discovery of endangered species or historical artifacts on-site.
