Station. PCH Sewer, and City Monitoring System DUring the design of the PCH Sewer,
Closed Circuit TelevIsion (CClV) mspectlons disclosed earthquake-related damage to the
Mam Street sewer, which IS the downstream connection to the PCH Ime The Federal
Emergency Management Agency (FEMA) has prepared a Damage Survey Report (DSR)
for an additional $1 6 million for the repair of the Mam Street sewer Staff recommends
that the contractor should design both sewers concurrently for greater coordination and
cost effectiveness
DIscussion
FEMA and the State's Office of Emergency Services (OES) are expected to reimburse
100% of the costs for the earthquake- damaged sewer line repairs and the City Will fund
additional costs for any necessary sewer line capacity upgrading Staff has been meetmg
with the City of Los Angeles regarding their portion of the upgradmg costs The City of Los
Angeles contributes a sizable portIOn of the total wastewater flow Into the Moss Avenue
stalion and Will be responsible for their fair share of the cost to upgrade both the station
and the northerly part of the Coastal Interceptor System (CIS) The flow IS combmed With
the rest of the City's flow m the Mam Street portion of the CIS All the wastewater IS then
transported to the Hyperlon plant for treatment The cost sharing percentages for the
southerly part of the CIS Will be adjusted accordmgly to reflect the actual flow components
of both cities Staff recommends that the deSign portion of the project move forward prior
to final funding approval by FEMA to ensure coordmatlon With other sewer projects In the
2
VICInity There are sufficient funds In the Wastewater Fund to cover the design costs
proposed In this report should FEMA not give final approval
BudgetlFlnanclallmpact

repair project for the full amount requested However, the City has not yet received the
DSR approval for the Main Street portion of this project Staff anticipates that FEMA and
OES will reimburse 100% of the Main Street DSR as It has all other sewer repair DSRs,
but since thiS approval has not offiCially arrived yet, staff recommends that funds from the
Wastewater Fund be used
