DISCUSSION
Background
The replacement of aging, deteriorating, or deficient wastewater collection system pipelines is
part of an ongoing sewer capital improvement program. This program has several objectives;
provide uninterrupted sewage flow, eliminate potential health hazards and/or effluent leakage,
and reduce the need for emergency repairs and maintenance. Furthermore, repairing defective
components of the City’s wastewater collection system reduces the infiltration/inflow of
groundwater and surface runoff and thus save operating costs and limit or eliminate future
overflows.
Project
This project will replace approximately 332 linear feet of sewer main by”pipe bursting” in an
easement area between Foothill Boulevard and Rougeot Place, as shown on Attachment C. The
existing six-inch clay sewer main was installed in 1927. The existing sewer main has significant
root intrusion and is on a four-month maintenance schedule to prevent backups and the potential
sanitary sewer overflows.
The project also includes the installation of a new sewer lateral at 26 Chorro and connecting
existing sewer laterals to the new eight-inch, high-density polyethylene (HDPE) sewer main. The
pipe bursting construction allows for the trenchless installation of a new, larger sewer main
inside of the existing sewer main. Replacing these sewer mains will result in lower maintenance
costs to the City and reduced residential impacts associated with emergency repairs.

Previous Council or Advisory Body Action
This project is identified in the Council approved 2017-19 Financial Plan. Project construction
has been delayed until now due to availability of staffing to finalize construction documents.
Policy Context
The City Council approved the Wastewater Collection System Infrastructure Renewal Strategy in
January 2016. The plan identified a strategy for prioritizing pipeline replacement in the
wastewater collection system to serve existing customers and future development in the City.
Per the October 2018 Financial Management Manual, Council approval is required for Public
Projects that cost over $175,000.
Public Engagement
Public engagement was done during the initial identification of this project to be included in the
2018-19 Financial Plan and again during the preparation of the construction documents.
Residents that will be affected from construction operations will be notified of the upcoming
work to reduce adverse impacts.
CONCURRENCE
There is concurrence from the Utilities Department of the project need based on conditions of
existing infrastructure and upon the review of the Project plans and special provisions.
ENVIRONMENTAL REVIEW
This project is categorically exempt from environmental review pursuant to section 15301 of the
CEQA Guidelines (Existing Facilities) since it is a maintenance and replacement project of
existing public facilities. A Notice of Exemption will be filed through the Community
Development Department.

Project Budget (91640) $120,000
I/I Reduction Funds (91739) $150,000
Total Funding Available $270,000
This project is identified in the 2017-19 Financial Plan, Page E2-143. Portions of this project’s
funding is available in the project account (91640) which has a current balance of $120,000.
Staff is recommending that additional funding of $150,000 be transferred from the I/I Reduction
project (91739) to provide sufficient funding for the project.
ALTERNATIVES
Deny authorization to advertise. The City Council may choose to not authorize project
advertisement. Staff does not recommend this alternative. Further delay of rehabilitating this
segment of wastewater collection system will only increase the costs associated with the
maintenance, emergency repair after complete failure, and construction phase of work.
