WHALE ROCK COMMISSION REPORT REM NUMBER
FROM: Allen Short, Water Division Manager
SUBJECT:
Annual Budget and Financial. Statement
BACKGROUND:
Attached are the Budget sheets for the Whale Rock Reservoir and the
Whale Rock Fishing Programs. They include a summary of revenues,
expenditures and changes in. the fund balance along with operating
and capital expenditure detail, member agency charge computations,
and operating program budget narratives from the City of San Luis
Obispo's 1989-91 Financial Plan.
This budget follows the same budget process as the City of San Luis
Obispo; it is the second year of a two-year budget cycle.
Significant Budget Changes
1. Staff is recommending that the Whale Rock Conveyance and.
Pumping System be upgraded. The project was not identified
in the CIP program for fiscal years 1989-91. However, there
are adequate funds in the fund balance to fund the project.
The project is estimated to cost approximately $868, 000.
2. Staff is in the process of obtaining two additional appraisals
on the. Mainini property. The cost of the appraisals is
estimated at $12.,000. This was not originally identified or
included when the budget was developed in. 1988-89.
3. Because of the drought, power costs are expected to remain a
significant portion of the Operations Budget. The 1989-90
budget for electrical was $335,000. Staff is projecting
expenditures of $300,000. The 1990-91 budget for electrical
expenditures is $275, 000. If similar conditions are exhibited
in 1990-91, staff expects to expend $300, 000. This will
require an additional $25, 000 to be budgeted for electrical
costs for 1990-91.
Operating Budget
The total recommended budget for fiscal year 1990-91 is $1, 543 , 000.
The proposed operating budget for 1990-91 is $ This is
a slight reduction over the 1989-90 budget. The primary reduction
is due to a reduction in capital projects.
Fund Balance
If the Conveyance and Pumping System upgrade is approved, the money
will be obtained from the fund balance. The fund balance will be
( reduced to a projected end of the year balance of $387, 000.
Current policy is to carry a minimum fund balance of 20 percent of
WHALE ROCK COMMISSION REPORT
Annual Budget and Financial Statement
Page 2
the operating budget. For 1990-91, this minimum amount would be
$135,000. However, because State agencies require a long lead time
for budget approval and to obtain money, it might be appropriate
to maintain a higher fund balance.
RECOMMENDATION
By motion, approve the 1990-91 budget with significant budget
changes as requested and provide staff direction on the fund
balance level.

PROGRAM DESCRIPTION
The Whale Rock Commission is a joint powers agency with six voting members who represent three
state agencies and the City. This commission was formed to build the Whale Rock Reservoir and
set policy for its operation. The City of San Luis Obispo, California Men's Colony (CMC), and
California Polytechnic State University (Cal Poly) are the actual water users, sharing the
costs and benefits of the reservoir in proportion to their original investment: City (55%);
Cal Poly (34%); and CMC (11%).
The Reservoir Operations Program provides for raw water storage in a 40,600 acre-foot
reservoir and raw water delivery through 19 miles of conduit and two pump stations to the
agencies of the Whale Rock Commission. The program goal is to provide a reliable, easily
treatable supply of raw water.
The program consists of six major activities: C
1. Water collection, storage, and delivery - Collect, store, and pump raw water to member
agencies and other customers.
2. Surveillance - Patrol and inspect the dam, reservoir, conduit and pump stations to
prevent vandalism and contamination.
3. Equipment maintenance - Perform periodic preventive maintenance, repair damaged
equipment, and replace worn and obsolete parts.
4. Recordkeeping - Prepare records and reports for local, .state, and federal agencies.
5. Power generation - Generate electricity from a 48 kilowatt turbine generator for sale to
Pacific Gas & Electric in an estimated amount of $9,000 for 1989-90.
6. Groundwater recharging - Release and pond water to recharge aquifers used for the town of
Cayucos.

WHALE ROCK COMMISSION REPORT MW NUMBER:
FROM: Allen Short, Water Division Manager
SUBJECT:
Leasing ponding area from the Mainini Family
BACKGROUND:
The Whale Rock Commission has historically used a 7.89 acre (pond)
parcel located on the Mainini property to recharge the underground
water aquifer. The Whale Rock Commission has leased the ponding
area from the Mainini Family for approximately ten years at $160. 00
per month ($1,920.00 per year) . The ponds consist of five (5)
large basins which assist in the recharge of the underlying aquifer
that provides the Cayucos Area Water Organization CAWO with water.
The Well Rock Commission is obligated by agreement to provide CAWO
with a maximum of 100 acre feet per month or 600 acre feet per
year. The ponds have been one of the mechanisms the Commission has
used to recharge the water aquifer.
Historically, staff has operated and maintain the ponding area.
To enhance percolation, periodic pond maintenance is required.
This includes the ponds dredging and weed removal at a cost of
approximately $10, 000 per year. Each time this event occurs, the
basins are dredged and this cost is incurred once every 4-5 years.
For the past ten (10) years, the Commission has had a "handshake
agreement" with the Mainini Family. This arrangement has been
satisfactory until October of 1988. At this time, the Mainini
Family requested a substantial increase in the lease payment.
Presently they are requesting an annual payment 'of $6, 000. 00 per
year which represents a 312.5 percent increase.
The Whale Rock staff and attorney have been working with the
Mainini Family and their attorney to draft an agreement which would
be mutually acceptable to each of the parties involved. Some of
those concerns include water for the cattle and maintenance of
roads crossing ponding areas. However, the most serous concern is
the rent issue. Staff has offered to increase the lease payment
by 100 percent or $4,000.00 per year. This is not acceptable to
the Mainini Family.
At the November 27, 1989 Whale. Rock Commission meeting, staff was
directed to:
1. Investigate the possibility of purchasing the entire portion ,
as outlined in red, white and blue on the attached map.
2. Include two separate appraisals and an indication of whether
the Mainini family would be willing to sell the property.
On February 7, 1990, after staff had began the process of obtaining
appraisals, received a letter from the attorney representing the
0 0
WHALE ROCK COMMISSION REPORT
Leasing ponding area from the Mainini Family
Page 2
Mainini family. The letter indicated that the .initial offer of
$4, 000 per year was adequate and they would like to enter into an
agreement with the Whale Rock Commission.
Additionally, the Whale Rock staff has contacted the Mainini family
regarding the sale of the property. The family has indicated
strongly that the property is not for sale at this time.
Staff is in the process of obtaining two separate appraisals. This
process is scheduled to be completed by the end of July 1990.
Staff will then be in a position at the October Whale Rock
Commission meeting to make a recommendation.
Additionally, staff has continued to pay the Mainini Family an
annual fee of $1920 per year until this item has been fully
resolved.
RECOMMENDATION
By motion, receive and file the Mainini pond leasing report.

WHALE ROCK COMMISSION REPORT MEM NUMBER:
)FROM: Allen Short, Water Division Manager
SUBJECT:
Chorro Pump Facilities Transfer Agreement and Operational
Procedure for the California Mens Colony
BACKGROUND:
Before the design, construction and operation of the Chorro Pump
Station, the California Men's Colony's (CMC) ability to obtain
water from Whale Rock reservoir was costly and very inefficient.
Historically, for CMC to obtain water, the city's Water Treatment
Plant staff would reduce the flow coming into the plant for
processing. By reducing the flow into the plant, the water would
back up in the Whale Rock line discharging into CMC'S process
train. The pumps from Whale�Rock Reservoir would be required to
work harder to supply CMC and the City's Water Treatment Plant with
water under this method of operation.
To increase the efficiency and reduce power costs associated with
providing CMC with water, a system evaluation was undertaken. At
the January 31, 1985 Whale Rock Commission Meeting, staff presented
its recommendation. The Commission approved and directed staff to
have two pumps designed and installed on the Chorro lateral, each
capable of handling normal operations and when used together,
capable of handling extreme demands. It was further recommended
that the Whale Rock Commission pay the capital costs for
construction and CMC pay the power bills and the operation and
maintenance costs.
The project was completed and became operational around May 1987.
On September 16, . 1989 operational problems developed with the
Chorro Pump Station. Whale Rock staff was requested to repair the
pumps and return them .to operational status. Prior to authorizing
staff to proceed with the repairs, the Whale Rock Commission staff
reviewed the past Commission meeting minutes to determine which
agency has responsibility for the operation and maintenance of the
pump station.
Upon review, staff was unable to find a formal agreement or
transfer of responsibility. However, the agenda report recommended
the operation. and maintenance costs associated with the project be
paid by CMC. Additionally, it had always been staff' s
understanding that CMC is the lead agency and fully responsible for
all of the operation and maintenance costs. If requested, the
Whale Rock staff could provide technical assistance and facilitate.
All costs would be incurred by CMC.
This item was placed on the November, 1989 Whale Rock Commission
Meeting. At that meeting, staff was directed to develop a formal
agreement and transfer of responsibility. Additionally, when the
City uses Whale Rock water as its sole source, CMC is unable
because obtain the design flow from the Chorro Pump Station because

of inadequate back pressure. To eliminate this problem and
artificially create the required back pressure, an operational
procedure was also requested.

repare y: Harold Fones
FROM: Utilities Manager Utilities Engineer
SUBJECT: Chorro Pumps Summary
BACKGROUND:
The attached report goes into the details , however the main points are
as follows .
The existing arrangement requires more electricity than a revised
pumping plan with separate pumps to supply the Chorro Facility . This
is because the Chorro Facility is at a higher elevation , which requires
the pumps to raise the pressure above the necessary level for most of
the water deliveries .
The present pumping costs are shared on the ratio of water delivered .
The revised plan would not raise the power costs for the Chorro
Facility, it would lower the costs for the other facilities . Chorro
would also have more flexibility in' their operations .
3stimated savings are $25 , 000 per year .

SUBJECT: Chorro Pumps
BACKGROUND:
Over the years , installation of pumps on the Chorro lateral have been
proposed to save energy. This is more important now with increased
power costs and increased usage of whale Rock water .
Let us consider the most energy efficient manner to deliver water to
the owners of the Whale Rock system. The dam holds water storage at
a maximum elevation of 216 feet at .the spillway . There are two
pumping plants with a total pumping capacity of 1 , 100 H . P . and the
high point in the thirty inch diameter pipe has a water surface
elevation of 549 .7 feet .
It would be possible to deliver all the water needed by the City of
San Luis Obispo and Cal Poly at the following rates of power usage ,
by pumping it up to the 550 elevation .

The increased power consumption is the result of more pipe friction
with the higher rates of flow. In this report , all pump efficiencies
are computed at 65% . .

Chorro Facility
The delivery of water to Chorro Reservoir is through 4 , 070 feet of 12
Inch pipe . The pipe branches from the 30 inch Whale Rock line , goes
up over the dam at elevation 598 and drops into the Chorro Reservoir
at approximately the elevation of 580 feet . There is a branch at the
dam that could turn the water directly into the Chorro Treatment
Plant at the elevation of 620 feet . The plant operators should have
the flexibility to use either option . This they do not have under
existing rules of operation.
Below are the power requirements to deliver water from the Whale Rock
conduit to the Chorro Reservoir or to the Chorro Treatment Plant .

Other_Pro.blems
I . Flog_Rates
Another problem with the delivery system is that it has a limit on
its capacity to deliver water . During the drought , all the pumps
were used for the month of October 1977 . The peak delivery was 7 . 6
M.G.D . and the average was 7 . 2 M. G . D . Taking into account the
reduced level of the reservoir , the deliveries to Chorro , and the
usual pump efficiencies , the rate of delivery should have been 8 . 9
M. G .D . Some of the difference is due to excess line pressure and
there are two other potential problems . The pump efficiencies may be
below par and our flow meters may need to be calibrated. Pumps on
the Chorro Line will increase our potential delivery rate to 10 . 0
M.G .D . .
II . Coordination
At the present time , all three water users can turn their valves any
time they choose . This is very desirable for the water user , but
presents a major problem to the water supplier when there is 16 miles
Of pipe and 1 , 100 horsepower pumping into a closed system.
Consider the problem that if Chorro wants 1 , 000 G . P .M. and is the
only water consumer . The smallest Whale Rock pumps put out about
2 , 000 G .P.M. and once again our power efficiencies drop.

MEETING DATE:
WHALE ROCK COMMISSION REPORT MEMNUMMR:
FROM: Allen Short, Water Division Manager
SUBJECT:
Provide the Whale Rock Commission Chairman with a greater
degree of authority in acting on behalf of the Commission and
establishment of quarterly meeting schedule.
BACKGROUND:
Historically, the Whale Rock Commission meets twice a year.
Occasionally, an emergency meeting is scheduled when an item
requires the immediate attention of the Commission. The twice-a-
year meeting approach has proven to be prudent and beneficial to
all of the agencies concerned. However, over the past year there
have been occasions that required the Commission to take action on
components of projects which had been previously approved or
authorized by the Commission.
This is best illustrated by the Coastal Streams Storage and
Diversion Project. Recently, the Consultant requested additional
funds and a modified scope of work to complete the EIR study. The
request was delivered to staff in December just prior to the rainy
season. It required immediate attention and approval so as not to
delay the project even further since the work required needed to
be performed during the rainy season.
At the March 13, 1990 Whale .Rock Commission .Meeting, staff was
given direction to begin the process of defining the areas for
increasing the Chairman's range of responsibilities. Staff was
also directed to develop a. quarterly meeting schedule.
AREAS OF INCREASED RESPONSIBILITY
To facilitate Commission business, staff is proposing to increase
the Chairman's range of responsibility and authority in the
following areas:
1. Contracting for professional services.
The services in this category include all specialized professional
services such as attorneys, architects, engineers, management
consultants and technical consultants. Staff is recommending that
the Chairman have the ability to approve these services up to
$25,000. Services exceeding $25,000 will require approval by the
Commission.
2. Purchase authorization.
Purchases in this category include those which do not exceed
$25, 000. Staff is recommending that the Chairman have the ability
to approve purchases up to $25,000 provided compliance with the
City of San Luis Obispo bid procedures.
WHALE ROCK COMMISSION REPORT
Whale Rock Chairman Authority
Page 2
3. Execution of modified minor agreements and contracts.
Under this category the Whale Rock Commission will have already
approved a contract or agreement. The contract or agreement will
require a modification to the scope of work which will require a
change in the agreed upon cost. Staff is recommending the Chairman
have the ability to approve modifications not to exceed $25, 000.
In any case, it will bethe responsibility of the Chairman to
report back to the Commission of all actions taken in between
regularly scheduled meetings. This can be accomplished by two
methods:
1. A brief summary of actions taken as part of the Whale. Rock
Commission meeting.
2. Incorporation of actions taken within the bi-monthly update
to the Commission members.
Staff recommends the Chairman use both options as required.
QUARTERLY MEETING SCHEDULE
i
Development of a quarterly meeting schedule will enable the
Commission to meet more frequently (if .required) to address those
issues of concern. Staff is recommending the Commission meet the
third Thursday of each of the months identified below:
1. June 90
2. October 90
3 . February 91
4. June 91
If a Commission meeting is not required, staff will inform the
Commission within 30 days of the meeting date.
RECODOMNDATION
Staff recommends that the Commission, by motion:
1. Provide direction to staff on the operational guidelines and
policies to provide the Whale Rock Commission Chairman with
greater authority in acting on behalf of the Commission.
2. Approve the quarterly meeting schedule as recoftended.

C0 MEETWG DATE:
WHALE ROCK COMMISSION REPORT FEM NUMBER:
FROM: Allen Short, Water Division Manager
SUBJECT:
Whale Rock Reservoir Pumping Capability and Conveyance
System.
BACKGROUND:
The City retained the firm of Leedshill-Herkenhoff to perform a safe
annual yield study on the Salinas Reservoir and on the coordinated use
of the Salinas and Whale Rock Reservoirs. During the study it was
ascertained that the Whale Rock conveyance system was in need of
additional pumping capacity to meet peak summertime demands.
In addition, because of the unusually dry conditions, the pumping
system at Whale Rock is continuously operating at maximum output.
Under these conditions with all six (6) pumps in operation, there are
no standby or backup pumps in case of a pump failure. As a result, if
a pump failure occurs Whale Rock will be unable to meet its delivery
demands until the repair is completed.
The Whale Rock pumping system is over twenty (20) years old and has
provided excellent service and reliability. However, because of age
and length of service we anticipate problems could occur. In addition,
when the pump stations were constructed expansion capability was built
into the design. As a result, there are locations at each pumping
station where additional pumps could be installed with minimal effort. j
The consulting firm of Leedshill-Herkenhoff, Inc (LH) and the Whale
Rock Commission entered into to an agreement on July 15, 1989 to
develop and recommend cost-effective alternatives for increasing the
conveyance capacity and reliability of the Whale Rock Project system.
The study has been completed and is attached for your review. The
report contains recommendations for each component of the system. If
the recommendations are implemented, it will assist in improving the
reliability of the current system and the ability to move more water
for all of the member agencies.
Based upon the investigation by LH, the original design information
indicates that the pipeline was sized to flow 12.2 MGD. Currently the
pipeline is able to convey a maximum of 9.9 MGD when the reservoir is
at elevation 216 (full 100%) and 7. 0 MGD when the elevation is 100 feet
(5.0$) .
ALTERNATIVES
The evaluation of the project developed five (5) alternatives and
analyzed each in terms of their advantages and disadvantages. The
alternatives are listed in order of staff's preference. They are:
1. Replacement of the existing electrical systems with a system that
can power 1, 000 horsepower pump stations and addition of 400
�.�-33
WHALE ROCK COMMISSION REPORT
Whale Rock Reservoir Pumping Capability and Conveyance System
Page 2
horsepower of pumping capacity at each pump station. Provision for
eventual replacement of the 150 horsepower pumping units with 200
horsepower pumping units. This alternative takes a phased
approached which addresses the capacity with the addition of 400
horse power of pumping capacity. But leaving the existing pumps
in place which than could be replaced as part of the capital
improvement project. The conveyance system capacity would be
increased by approximately 33 percent. Replacement of the
electrical system will increase system reliability. The expansion
is compatible with the existing facilities and would only require
minor modifications, unlike the alternative discussed directly
below. This alternative would also address the following:
a. Construction of anew soundproof concrete block building at
pump station A in Cayucos to replace the existing steel
building. Pump Station B would be expanded to house the two
new units.
b. Construct new electrical equipment for the new electrical
system.
C. Conduct a surge analysis of the pipeline to determine the
impact of the higher flow rate on the existing surge
protection devices.
d. Reconfigure the pipeline outlet at the Energy Partners
Powerplant to allow flows to bypass the Powerplant.
e. Add a backup power supply at each pump station.
f. Conduct a study of alternatives for increasing the peak
pumping rate of the Chorro Lateral Pumping Station. This
would be an additional cost which is estimated at $10, 060.
The estimated costs for the design and construction of the recommended
improvements excluding item number six is approximately $868, 000.
2. Replacement of the existing electrical system with system that can
power a 1500 horsepower pump station and replacement of the
existing pumping units with five (5) 300 horsepower pumping units
at each pump station. The alternative upgrades the electrical
system which increases system reliability. The conveyance system
would be increased by approximately 90 percent to 15 MGD. The
increase would be above the current system design and would require
other modifications such as surge protection. Additionally,
upgrading existing maintenance facilities would be required. to
handle larger equipment. This alternative address all of the
initial project concerns. The initial capital expenditure would
be approximately 1.4 million dollars.
3 . Replacement of the existing 550 horsepower electrical system and
no additional pumping capacity. This alternative addresses one of
the primary concerns of the electrical system. However, it does
not increase the conveyance capability. ' Additionally, it does not
address the concerns of pumping reliability or replacement.
WHALE ROCK COMMISSION REPORT
Whale Rock Reservoir Pumping Capability and Conveyance System
Page 3
4. Addition of a 200 horsepower pumping unit and expansion of the
existing electrical system to the capacity limit of 750 horsepower
at . both pumping stations. The alternative would expand the
conveyance by 20 percent at the lowest initial cost. However, this
does not address the antique electrical system or supply pumps.
It simply adds to the existing system and does not completely
address the reliability question.
5. Status Quo. This would require leaving the system as is. This
alternative has a number of disadvantages. The current system has
a number of problems with system age (electrical systems and pumps)
which reduces system reliability. The conveyance limitation would
not be addressed and the current problems would remain. The
problems with the Chorro Pump Station and Energy Partners Hydro
Stations would not be addressed. Staff does not recommend this
alternative.
CONSEQUENCES OF NOT TAKING ACTION
If additional pumps and upgrades to the electrical are not added to the
system, and if a pumping or electrical failure were to occur, whale
Rock Reservoir could not meet 100% of its delivery demands during the
summer months.
FINANCIAL IMPACT
As detailed in the Engineer's Estimate, the total estimated cost for
this project is $868, 000 which includes $180, 000 for engineering design
as summarized below:
Structural and Mechanical $254,000
Electrical $373,000
Surge Protection $105,000
Bypass at Outlet $ 101000
Backup Power $126. 000
$868,000
There is sufficient money in the fund balance to adequately fund the
project. The projected fund balance at the end of fiscal year 1990-
91 is estimated to be $1, 145, 376.
