In 2006, the State Water Resources Control Board adopted the Waste Discharge
Requirement Program for all publicly owned sanitary sewer collection systems in California with more than one mile of sewer pipeline. Under this program, the City was required to prepare and implement a Sewer System Management Plan (“SSMP”). The
SSMP identifies routine preventative operation and maintenance activities that assist
the City in achieving a goal of zero sewer system overflows. This is achieved through
annual inspections, routine cleaning of the sewer pipes, repair of broken pipes, and replacement of pipes flowing above their design capacity.
The City of Arcadia’s 2006 Sewer Master Plan study identified sections of sanitary
sewer pipe on Huntington Drive as inadequate in accommodating the current flows and
at risk of experiencing sewer overflows. As a result, in Fiscal Year 2015-16, the 10-inch

sewer pipe on Huntington Drive from Colorado Place to Centennial Way was replaced with a 14-inch sewer pipe. On May 2, 2017, the City Council approved a contract with
MNR Construction, Inc. for Phase 2 of the Huntington Drive Sewer Capacity
Improvement Project. The project included replacement of the existing 12-inch sewer
pipe along Huntington Drive between Centennial Way and the connection point to the Los Angeles County Sanitation District’s sewer system with a 16-inch sewer pipe. Replacing the 12-inch sewer pipe with a larger sewer pipe accommodates current and
future flows, alleviating the potential of a sewer back up and overflow.
The project was completed with a process that eliminates cutting a long trench in the street with a method called pipe bursting. This method involves bursting the existing 12 inch sewer pipe with a new larger 16 inch sewer pipe. The pipe bursting method
resulted in minimizing traffic impacts and reduced disruptions to businesses along
Huntington Drive.
All of the terms and conditions of this contract have been complied with and the work has been performed to the satisfaction of the Project Manager. MNR Construction, Inc.
completed the work as defined in the project plans and specifications in an efficient and
timely manner.
FISCAL IMPACT
Funds in the amount of $430,000 were budgeted in the FY 2016-17 Capital
Improvement Program for Phase 2 of the Huntington Drive Sewer Capacity
Improvement Project. The total cost for this project is $274,051. This amount reflects the original contract amount.
