RECOMMENDED ACTION:
Adopt Resolution No.8.&_l2£LJ approving a consultant agreement with
Wilson Engineering, Incorporated, for the design of the Vista/
Carlsbad Interceptor Sewer, Project No. 3182.
ITEM EXPLANATION;
Sewage from the City of Vista and the northern portion of the
City of Carlsbad flows through a large interceptor sewer to the
Agua Hedionda Pump Station and then to the Encinas Water
Pollution Control Facility. In downtown Carlsbad, the sewer
follows Jefferson Street south to Grand Avenue, then turns west
to the AT&SF Railroad right-of-way, and turns south again along
the railroad tracks.
According to the December, 1987 City of Carlsbad Sewer Master
Plan, anticipated growth demand for capacity in this major
interceptor will require expansion of the line by 1990. The
lengths of the sewer to be upsized run from Jefferson Street at
1-5 to a point along the railroad tracks south of Tamarack
Avenue. The City of Carlsbad currently owns from 27% to 37% of
the line's capacity; Vista owns the remainder. The variation of
percentages of ownership between the two (2) agencies depends
upon the location and flow within each individual reach of the
interceptor system. The ownership percentages of the interceptor
sewer after construction will reflect the relative capacity
demand of the two cities.
An investigation of alternative sewer routes will be made to
determine the best course for the new sewer. Routes that avoid
the village area of downtown Carlsbad will be given a strong
preference. Construction will be coordinated with the
Streetscape program so that new improvements are not affected.
Four (4) proposals from qualified engineering consultants were
reviewed by staff from the Cities of Vista and Carlsbad. Wilson
Engineering, Incorporated, was identified as the firm considered
most qualified for this project. The design proposal includes
preparation of design plans and specifications. Construction
inspection is also provided for the lump sum price of $139,600.
Staff recommends approval of the attached consultant agreement.
FISCAL IMPACT;
The City Council has previously appropriated a total of
$2,520,000 in the 1985-86 and 1986-87 Capital Improvement Program
budgets for the Vista/Carlsbad Interceptor Sewer replacement
_ project. Of that amount, $200,000 was subsequently transferred
O from the project account for the design of the upgrade of the
3 Agua Hedionda Pump Station which is nearing completion.

Page Two of Agenda Bill No.
Design costs of $139,600 will be paid directly by the City of
Carlsbad subject to reimbursement by the City of Vista upon
execution of a formal agreement specifying each City's usage and
cost share in the system. An estimate of construction costs will
be available when the preliminary design and route study is
completed. Construction and design costs will be paid by the
City of Vista in proportion to the capacity rights required for
their current and future development.
