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.
