Challenges and Considerations in Undergrounding Electrical Lines to Prevent Brush Fires in Southern California

Preview
Southern California authorities have not trenched existing electrical lines underground to prevent future brush fires primarily due to the significant cost and time involved in such a project. Burying power lines is up to ten times more expensive than installing overhead lines, making it a financially challenging endeavor for utility companies and the state. Additionally, the process of undergrounding lines is time-consuming and requires extensive planning and execution, which can delay other critical infrastructure projects and maintenance efforts.

Moreover, while undergrounding power lines can significantly reduce the risk of wildfires, it does not eliminate all risks. Underground lines can still be damaged by other factors such as flooding and earthquakes, which are not uncommon in California. Therefore, the cost-benefit analysis often does not favor widespread undergrounding, especially when other mitigation strategies like fireproofing equipment and vegetation management can also be effective.

In summary, the high cost, lengthy implementation time, and the presence of other risk factors make trenching existing electrical lines underground a less feasible option for preventing brush fires in Southern California.
