Coordinate communication with So. California Edison and
Sempra Energy Co. for restoration of services. Provide contacts
for vendors of rental generators and initiate mutual assistance
between unaffected agencies for emergency backup power.
Consult with the impacted utilities and the California
Department of Public Health (CDPH) for water quality concerns
and public notices.
Coordinate the resources necessary for repair of the Orange
County water and wastewater agencies’ infrastructure.
Facilitate mutual aid from outside agencies through the Orange
County Operational Area utilizing the above mentioned mutual
aid agreements. Utilize WEROC Mutual Aid Directory and
private vendor lists to identify available water haulers,
temporary water lines, piping, heavy equipment, etc.
If time allows, notify coastal agencies to take the appropriate
actions for life safety; and if there is time protection of
infrastructure. Request CDPH support in evaluating water
contamination via salt water intrusion and backflow of raw
sewer water. Support agency efforts to restore water flow in
unique conditions of flooding (safety) and potentially lack of
electricity. Continue support similar to an earthquake response.
Since such an incident typically involves a long-term response
with law enforcement. WEROC could support the agency with
staff, communications with the County, and resources required
for recovery of operational systems. In addition, coordination of
WEROC water quality advisors, CDPH, and public information
officers will be critical.
Coordination with the Orange County Public Works Department
for flood control support. Coordination of mutual assistance for
repair of infrastructure.
Identify impacts to water resources and resource management
for the county during the current weather season and
conditions. Evaluate the need and ability for accelerated
reconstruction and/or restoration of services.
Work with the CDPH and the Orange County retail water
agencies that have open water sources to determine impacts to
water quality and appropriate protective actions. Work with
agencies within the fallout zone to determine current
operational capabilities and future use of infrastructure in the
affected area.
Coordinate with Fire Unified Command Post to ensure that
information and resource needs are being met. Ensure that fire
protection is being provided to critical infrastructure and that
