Community Benefits

This work will result in enhanced electrical reliability and reduce the likelihood of unplanned power outages in the area.

Anticipated Impacts

  • Power outages are required to complete the work safely. We typically notify affected residents five days in advance of any planned power outages.
  • Crews will work in the public right-of-way (e.g., street and planting strips). They will cover active work areas with steel plates outside of construction work hours. These plates are safe to drive on.
  • Private service connections to homes are not included in this work. If homeowners would like to upgrade their property’s electrical service, they will need to submit an electrical service request. Please review our electrical service guidance for more information.

During construction, customers can expect:

  • Limited parking and sidewalk access.
  • Limited driveway access to houses closest to active work areas. Vehicles will be able to pass during non-working hours.
  • Traffic signs and flaggers redirecting pedestrian and vehicle traffic to maintain safety.
  • Traffic delays near active work areas.
  • Some equipment noise during work hours.
  • Restoration to follow SDOT guidelines.
  • City Light’s Resident Engineer onsite daily to monitor project activities.

Schedule

Tentative Construction Start: Q1 2027
Estimated Duration: 4 - 6 months
Daily Work Schedule: To be determined

Please note: Crews may need to work on projects in other parts of our service area before starting this project. This may push the anticipated start date for the Shoreline Innis Arden Underground Cable Replacement Project back. We will publish updates to the project web page as needed. Thank you for your patience and understanding.
