RECOMMENDED ACTION:
Adopt Resolution No. 2007-076 appropriating funds in the amount of $500,000 for the repair
of a ruptured sewer force main at Buena Vista Lagoon.
ITEM EXPLANATION:
The Vista/Carlsbad Interceptor (Reach 4) is a joint facility owned by the City of Vista and the City of
Carlsbad. Ownership of the interceptor is 89.6% and 10.4%, respectively, based on the "Agreement
for Ownership, Operation, and Maintenance of the Vista/Carlsbad Interceptor Sewer" ("Agreement"),
which Vista and Carlsbad entered into on February 26, 2002.
On Sunday, April 1, 2007, at approximately 7 pm, the portion of the line running along Buena Vista
Lagoon was determined to be broken and leaking raw sewage into the lagoon. Due to the location of
the break along the shore of the lagoon, it was necessary to hire a contractor and build shoring
around the location of the leak prior to excavating the pipe and beginning the repair. The leak resulted
in an estimated five million gallons of sewage being spilled into Buena Vista Lagoon, a State of
California Ecological Reserve.
The cost to install the sheet pile shoring and pipeline repair is estimated to be $150,000. When the
shoring was originally put in place, it was anticipated that it would be removed after the necessary
repairs were facilitated. Upon further review, it has been determined that removing the shoring would
cause vibrations which could potentially cause liquefaction of soil under the pipe and any settlement
of the pipe would result in the repaired sewer line rupturing. Therefore, a decision to leave the shoring
in place was made. The additional cost for purchasing the shoring is estimated at $90,000.
Because of the size of the "spill and its proximity to an ecological reserve, environmental and water
quality monitoring is necessary. Additionally, mitigation for damage to the environment will probably
be required in the future. Current estimates for the cost of monitoring and reporting are $29,000.
Mitigation expenses are still being estimated.
Additional contractors and equipment rental, as well as the cost of mobilizing and supporting staff
on the scene of the spill bring the total estimated cost for this event to approximately $350,000.
In the event additional unforeseen costs occur, staff is requesting an appropriation of $500,000.
The City of Carlsbad and the City of Vista are anticipating that a fine for this incident will be levied by
the Regional Water Quality Control Board. If this should occur, an additional request for appropriation
will be made.

ENVIRONMENTAL IMPACT:
This repair is Categorically Exempt from CEQA review under section 15301 of the CEQA Guidelines-
repair of an existing facility.
FISCAL IMPACT:
This sewer line is jointly owned by the cities of Carlsbad and Vista. By agreement, the City of Vista
owns 89.6% of the reach and, therefore, would be responsible for the majority of the costs of this
repair. Carlsbad owns 10.4% of this reach. Carlsbad and Vista will share the costs of the repair,
monitoring, mitigation, and other expenses in the proportion of their ownership of the reach.
Staff is requesting an appropriation of $500,000 from the Sewer Capital Replacement fund to pay for
this repair. There are sufficient funds in this account to cover the expense.
EXHIBITS:

MEMORANDUM
April 5, 2007 CITY OF CARLSBADCITY CLERK'S OFFICE
C<L

TO: MAYOR AND CITY COUNCIL J><L
FROM: CITY ATTORNEY
RE- SUBSTITUTION OF RESOLUTION TO THE AGENDA BILL REQUESTING AN
APPRORIATION FOR EMERGENCY SEWER LINE REPAIR
The above referenced Agenda Bill will on your agenda for the meeting of April 10, 2007.
Please find attached a modified resolution for the bill. Since it has been decided to
leave the shoring wall as a permanent structure the project could take on the character
of a public project, which under ordinary circumstances may require compliance with
bidding statutes. It would therefore be prudent for the City Council to make a finding
that that the repair work has been done on an emergency basis and there was not time
to seek bids through the bidding process.
Please contact me or the City Manager should you need any additional information prior
to the meeting this evening.
