BACKGROUND
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 Duarte Road as inadequate in accommodating the current high demand
flows and at risk of experiencing sewer overflows. As a result, the existing sewer pipe

along Duarte Road between Baldwin Avenue was scheduled to be replaced in Fiscal
Year 2021-22.
DISCUSSION
On October 19, 2021, the City Council approved a contract with Ramona, Inc. for the
Sewer Main Replacement Program. The work performed included replacement of the
existing 12-inch sewer pipe along Duarte Road between Baldwin Avenue and Holly
Avenue, with a 16-inch sewer pipe. The project was completed with a method called
pipe bursting; a process that eliminated the need to cut a long trench in the street and
helped minimize traffic impacts and disruption to businesses and residents along Duarte
Road.
During work, the City received credits for a reduction in quantities of material needed to
complete the project. Below is a breakdown of total contract change orders.
CCO Description Amount
1. Deleted (1 EA) – Locate and Reconnect Existing Sewer Laterals ($1,400.00)
2. Deleted (13 LF) – Pipe Burst 12” Pipe to 16” HDPE DR 17 Pipe ($3,211.00)
Total ($4,611.00)
The change orders listed reduced the overall contract amount by $4,611, or 0.5% less
than the original contract amount. All terms and conditions of this contract have been
met and the work has been performed to the satisfaction of the Project Manager.
Ramona, Inc. completed the work as defined in the project plans and specifications in
an efficient and timely manner. Photographs of the Sewer Main Replacement Program
are shown on Exhibit “A”.
FISCAL IMPACT
Funds in the amount of $1,200,000 have been budgeted in the FY 2021-22 Capital
Improvement Program for the Sewer Main Replacement Program. The total
construction cost for this project is $953,789. This amount reflects the original contract
amount of $958,400 minus change orders totaling $4,611, or 0.5% less than the original
contract amount.
RECOMMENDATION
It is recommended that the City Council accept all work performed by Ramona, Inc. for
the Sewer Main Replacement Program as complete; and authorize the final payment to
