• As part of our long-term plan to upgrade and modernize our grid, Southern California Edison (SCE) is making electrical upgrades in Manhattan Beach and across the region.
• At SCE, it is our job to make sure that our customers have the robust electrical infrastructure needed to continue to power their future energy needs.
• Upgrading to newer equipment will make the power grid up-to-date and minimize the likelihood of unanticipated and extended outages.

El Porto Project Overview
7
• SCE reviewed circuit loading and circuit outage history for the area, outage causes, & identified areas for improvement
• Meet load growth electrical demands by cutting over 4kV circuits to 16kV circuits
• Construction activities will include:– Replace over 660 poles
– Install 154 new transformers
– Upgrade equipment in existing underground structures

Anticipated Work Activities
9
• Construction will begin mid-September 2014 through mid-2015 – This schedule may change due to weather and other factors
– Construction will not occur at one location throughout this entire period; crews will move from location to location as work is completed
• Crews may need to access your property to replace poles. You will be notified when crews enter the property.
• During construction, there will be lane closures. SCE will use a combination of traffic control signs and crew members with flags to ensure vehicle and pedestrian safety.
• For crews to work safely, it will be necessary to de-energize our power lines for short periods of time. In these cases, SCE will send notices to affected customers at least 72 hours prior to maintenance outages.
