DISCUSSION
Background
The Jennifer Street Sewer Line Replacement project includes the replacement, rerouting and
abandonment of existing structurally unsound clay sewer mains that date from the early 1900s.
The project includes jack and bore construction under the Union Pacific railroad tracks for the
installation of a 15-inch welded steel encasement and 8 inch sewer line, open trenching for the
installation of the new eight-inch sewer main, and installation of approximately 660 feet cured-
in-place six-inch pipe liner. The project will reroute wastewater flow to a portion of the
collection system that was upgraded in 2013. The project also includes installation of 760 feet of
eight-inch sewer main along the City’s bike path, abandonment of 650 feet of sewer line under
the railroad at the intersection of Rachel and Florence Streets to Santa Barbara Road, and
redirects a portion of the flow to the collection system that was upgraded in 2011.
ENVIRONMENTAL REVIEW

FISCAL IMPACT
This project is identified on page 3-160, of the 2013-15 Financial Plan, Capital Improvement
Plan. All project funding is derived from the sewer fund and includes a construction budget of
$300,000 for the Jennifer Street and $400,000 for the Rachel Street railroad crossing projects. An
additional $237,000 and $144,000 was added to the Jennifer and Rachel Street project budgets ,
respectively, during the budget supplement in June 2014, resulting in a total project budget of
$1,081,000. The total project budget includes funding for design, easement acquisition,
construction, and construction management services. Easement acquisition was completed in
October 2015.
The Engineer's estimate for construction of the project is $802,000. The project budget is
displayed below.
Because of the potential to encounter contaminated soil within the railroad corridor, the bid
documents include a bid item for the preparation of a health and safety plan and excavation and
containment of contaminated soils.
A total of $1,040,000 is available in the Wastewater Collection System Master Account to
support this project.
ALTERNATIVES
Deny or defer approval to advertise. The City Council may choose to deny or defer the approval
to advertise this project. Staff does not recommend this option, as the sewer main will continue to
deteriorate and pose a high risk of catastrophic failure, resultant in sewer overflows, water quality
violations, and potential fines.
