Thanks for reporting this issue! This issue is located in a Caltrans right-of-way. This means that the department has to pull a permit from Caltrans before work can be performed at this location. The process to get an approved permit can take several weeks to several months. We will continue to provide updates on this issue as it becomes available. Thank you for your patience and understanding in this situation.
