RESOLUTION NO. 2006-245
RESOLUTION OF THE CITY COUNCIL OF THE CITY OF
CHULA VISTA APPROPRIATING $550,000 FROM THE
AVAILABLE BALANCE IN THE TRUNK SEWER CAPITAL
RESERVE FUND TO THE SALT CREEK SEWER
INTERCEPTOR (SW-2l9) PROJECT AND AUTHORIZING
THE USE OF THESE FUNDS AND OTHER AVAILABLE
PROJECT FUNDS TO BE USED FOR THE REPAIR OF
DAMAGED PUBLIC INFRASTRUCTURE AND THE
MITIGATION OF POTENTIAL FUTURE DAMAGES DUE TO
TRENCH SETTLEMENT AND UNFORESEEN SUBSURFACE
CONDITIONS ASSOCIATED WITH THE CONSTRUCTION
OF THE SALT CREEK INTERCEPTOR SEWER
WHEREAS, beginning a little more than two years ago, pavement failures and water
lateral breaks began occurring within the trench limits of the Salt Creek Interceptor Sewer at
various locations under Main Street, between Industrial Boulevard and Heritage Road; and
WHEREAS, most of the water lateral failures would be considered catastrophic as they
occurred suddenly and unexpectedly, disrupted business and travel along Main Street, and
required immediate and costly repairs; and
WHEREAS, water lateral failures have occurred primarily with 4" and larger diameter
asbestos cement pipe and failures became more frequent during the 2004/2005 rainy season; and
WHEREAS, these failures have resulted in substantial damages to both Sweetwater
Authority's and the City ofChula Vista's facilities; and
WHEREAS, both the City and Sweetwater Authority ("agencies") staff have concluded
that the series of failures has resulted from migration of the underlying soils supporting the water
laterals; and
WHEREAS, future failures of settlement-sensitive water services are likely to continue as
these unforeseen conditions persist within and adjacent to the trench; and
WHEREAS, Sweetwater Authority and the City have incurred several hundred thousand
dollars to date in repair costs related to failure of asbestos-cement water services; and
WHEREAS, the agencies' staff have worked jointly to identify solutions to significantly
reduce the risk of these catastrophic failures occurring in the future, as well as validate their
understanding of the underlying failure mechanisms; and
WHEREAS, the agencies will share the cost of replacing thirty-six settlement-sensitive
water services that were under-crossed by the Salt Creek Interceptor Sewer; and
WHEREAS, as timely repairs to the roadway are necessary to address hazardous
roadway conditions, staff recommends hiring a paving contractor under a Public Works contract
on an as-needed, time-and-materials basis to perform pavement repairs needed now and over a
one-year contract period; and

WHEREAS, geotechnical investigation will be performed during repairs to both the ___.
water laterals and the pavement failures to better understand the failure mechanism(s) and to
establish recommendations for remediation with a high potential for success; and
WHEREAS, approximately $32,000,000 has been allocated to the project to date; and
WHEREAS, staff is requesting an additional total appropriation of $550,000 from the
Trunk Sewer Capital Reserve Fund; and
WHEREAS, any requests for allocations to repair any future damage to public
improvements caused by trench settlement will be included in the Department of Public Works
Operations' annual operating budgets.
NOW, THEREFORE, BE IT RESOLVED that the City Council of the City ofChula Vista does
hereby appropriate $550,000 from the available balance of the Trunk Sewer Capital Reserve
Fund to the Salt Creek Sewer Interceptor (SW-219) Project and authorizes the use of these funds
and other available project funds to be used for the repair of damaged public infrastructure and
the mitigation of potential future damages due to trench settlement and unforeseen subsurface
conditions associated with the construction ofthe Salt Creek Interceptor Sewer.
