SUBJECT:
AUTHORIZATION FOR PHASE II OF WATER CAPITAL IMPROVEMENT PROGRAM
MANAGEMENT
RECOMMENDATION
That the City Council authorize Phase II of the Water System Capital Program Management Services with
ASL Consulting Engineers.
FISCAL IMPACT
The original contract, which was approved by the Council on January 15, 1996, was structured in 5 phases
with only Phase I being initially authorized. The requested recommendation involves only the funding of
Phase II for $98,700. Funding for Phase II is from the existing debt issuance of Water Certificates of
Participation. It is anticipated that funding for Phase III through V, amounting to approximately
$829,000, will be funded through future bond sales and will be brought to the City Council in separate
phases for approval. The proposed contract amendment does not obligate the City to continue with
Phases III through V or continue to use ASL for the future work.
BACKGROUND
In October of 1990, Daniel Boyle Engineering, Inc., completed a Water System Storage Evaluation Study.
The Study determined that there were deficiencies in the system in both quantity of storage and structural
condition of existing reservoirs. It was determined that approximately $40 million worth of
improvements to the storage and distribution system were necessary.
In 1992 the City Council reviewed and approved a water rate study and financial plan prepared by Bartle
Wells Associates. The study proposed a funding plan to support a twelve year development program to
construct the recommended water system improvements. The financial plan proposed a series of bond
issues 'designed to support approximately two years of development costs. Subsequently, the first series
of bonds were issued in April 1993 to retire the outstanding 1983 water bonds and provide $6.9 million
for water system improvements. Currently, $4.5 million has been expended to complete the Rawlings
Reservoir Retaining Wall Replacement, Newport Avenue Transmission Main Replacement, the
Vandenberg Well construction and various distribution pipeline replacements.
Although great progress had been made, the total progran~ was approximately two years behind schedule.
In an effort to expedite the entire program and return to the original schedule, a request for proposal to

provide engineering management services for the remaining projects was prepared and sent to several
consultants. Although the current water services staff is very efficient at maintaining and operating the
existing water system, they do not have the technical expertise or the existing manpower to implement the
proposed .design/construction program schedule. Since the projects are essentially~, one-time
design/construction projects that improve our existing system, any design staff hired for the specific
project would no longer be needed upon project completion. Additionally, it would have been necessary
to hire experienced personnel and support staff and purchase additional computers and associated software
to complete these one-time design projects. Thus, the best use of existing and future manpower and the
most cost effective method to complete the twelve year program was determined to be through a qualified
engineering firm.
DISCUSSION
The program management contract was structured in five phases, with each phase requiring separate
approval by City Council. The first phase encompassed preparing a 7-year design/construction program,
completing site plans, acquiring the Main Street site, completing structural analysis of existing reservoirs,
and designing water main replacement projects. As of this date, the 7-year plan, the site plans, and the
selection of consultants for the Main Street site acquisition and the reservoir structural analysis have been
completed. The plans for the water main replacements are approximately 90% complete.
With continuing oversight provided by the Director of Public Works/City Engineer and the Water
Services Manager, the second phase services of the consultant will be to prepare scopes of work and
requests for proposals, assist in consultant selection; monitor consultant contracts and billings and
perform plan checking for the Phase II projects. As of this date, the projects that are included are the
designs of the Main Street Reservoir and pump station, Main Street Well No. 4 including wellhead
facilities and chlorination/fluoridation facilities, Rawlings Zone II Booster Pump Station, Simon Ranch
Booster Pump Station and the Phase II distribution system, improvements. Only those projects for which
funding is available will be authorized.
The consultant contract has also been structured with a pay for performance feature. The consultant has
been and will continue to be paid only upon completion of certain milestones which have been included in
the agreement.
