City Of San IDIS OBISPO October 30 1989
COUNCIL AGENDA REPORT
FROM: William T. Hetland PREPARED BY Allen Short
Utilities Director Water Division Manager
SUBJECT:
Increase the amount of money allocated for the Leedshill-Herkenhoff
Live Stream Study.
CAO RECOMMENDATION:
Adopt a resolution extending the current agreement with
Leedshill-Herkenhoff to reimburse Leedshill-Herkenhoff for the
additional service rendered on the impacts of downstream withdrawals
on the Salinas River "Live Stream" releases project.
BACKGROUND:
The City retained the firm of Leedshill-Herkenhoff to perform a safe
annual yield and coordinated operations study for Salinas and Whale
Rock Reservoirs. The study recommended that it may be possible to
increase the safe annual yield value from its current level.
However, an investigation and study concerning the impact of the
downstream withdrawals on the Salinas River "live stream" releases
should be undertaken.
To provide the City Council and staff with the essential information
needed to recommend and adopt long-term water planning decisions,
the downstream water use and "live stream" releases must be
addressed. Staff contacted Leedshill-Herkenhoff and requested that
they assemble a proposal to study the "live stream" issue.
The consulting firm prepared a proposal outlining the scope of work
and associated fee estimates for conducting a study of the potential
impacts that increased downstream water use may have on "live
stream" releases.
Under the proposal the consultant would perform the work in phases
as necessary to try and answer the issue. This type of approach
minimizes the cost and expedites the work. However, the potential
exists that additional costs would accumulate based upon the initial
results.
The City Council on March 14, 1989 adopted a resolution approving
the proposal with Leedshill-Herkenhoff to study the impacts of
downstream withdrawals on the Salinas River "live stream" releases
not to exceed $16,900.
As the project developed and the results were provided to the staff,
the scope of work was modified to address a variety of additional
questions and concerns.

The additional concerns addressed were:
1. To map all of the gauging stations.
2. Investigate the impact of dredging downstream of the dam.
3. Address the concern of sand bars located downstream of the
dam.
Additionally, the consultant was retained to present the material
before the City Council and address any of their questions or
concerns. As a result of the expanded scope of work and additional
tasks placed upon the firm, the amount of $16,900 is not sufficient
to cover the total cost of the project. It is recommended that the
contract be increased by $10,000.
Leedshill-Herkenhoff has completed the draft report and it has been
reviewed by City staff. Those comments are being incorporated into
the final document which will then be submitted and reviewed with
Council.
FINANCIAL IMPACT:
Base proposal $16,900
Additional Contract Amount $10,000
Total Project Costs $26,900
Adequate funds are available in the water fund budget. At mid year
staff will review the Administration and Engineering budget and
additional funding may be required for further unanticipated costs.
RECOMMENDATION•
Adopt a resolution extending the current agreement with
Leedshill-Herkenhoff and approve the transfer of additional funds to
reimburse Leedshill-Herkenhoff for the additional service rendered
on the impacts of downstream withdrawals on the Salinas River "Live
Stream" releases project.
