6. REPORTS
A. Kern River & Isabella Reservoir Operations Report
Miguel Chavez, Hydrographic Supervisor, gave an overview of the Kern
River natural flow, regulated flow, Isabella Reservoir storage, and snow
pack accumulation. Mr. Chavez stated since our last meeting, the Kern
River Basin has received significant storms that have raised the Snowpack
to above normal levels for this water year. Snow accumulation escalated
quickly during the months of January through March. The most significant
storm occurred on March Sh-6m, which produced an average of 6.5 inches
of snow depth across the Kern River Basin over a 48-hour period. Currently
the Department of Water Resources is forecasting a 170% of normal water
yield during the peak snowmelt months of April thru July and 150% of
normal water year which dates from October 2018 thru September 2019.
As of midnight, the Kern River inflow was at 4,883 cubic feet per second
(cfs), regulated outflow was 2,912 cfs and storage level at Lake Isabella
was 323,830 acre feet (of). The Kern River has had a continuous Flow from
Golden State Highway to the City's 2800 acres' spreading facility since
February 2019. During the months of February and March, the flows seen
in the river were a combination of Friant and State water supply. Kern River
Supply took over as the main source of water for the river on April 1Ir,
however Friant supply also was included for a period of time during April.
Currently, water can be seen flowing from Manor Street all the way out to
the City's 2800 acres spreading facility with the source of this water being
95% Kern River supply and 5% Friant supply. Looking ahead, we can
expect more of the some as the river should continue flowing through
August of this year. Mr. Chavez presented a slide regarding Lake Isabella
storage capacity comparison between February 10 and May 15'. The City
on May 1 Sr was utilizing 26% of total storage compared to 12% of storage
on February Pt, more than doubling storage in Lake Isabella. Also, Mr.
Chavez presented a slide showing how the City plans on utilizing its
estimated 225,000 at. water for the 2019 calendar year. Board information
only, no action taken.
B. Update on Water Usage in the City's Domestic Water Service Area for
March 2019
Art Chianello, Water Resources Manager, referenced graphs that show
the water usage for the City's Domestic Water Service Area from January
2019 through March 2019 and the monthly percentage reduction (or
increase) for the service area for the same period compared to the 2013
baseline. From January 2019 through March 2019 the City's Domestic
Water Service Area saved 695 acre feet compared to 2013 quantities. The
cumulative water savings over this time period is about 12% reduction from
2013 baseline. The water savings amounts stated are for total water
deliveries in the system. It should be noted that the City's Domestic Water
System has
Bakersfield, California, May 15, 2019 - Page 3
6. REPORTS (cont.)
grown over the past six years. In March 2013, the population served by the
City domestic water system was approximately 135,321 residents and in
March 2019, the population served is about 152,810 residents. This is a
population increase of about 11.4% over the six-year period. Therefore,
considering the population growth in the City's system and water use over
these time periods equates to a water use reduction of approximately
34.6% per person. This reduction is mainly due to the weather during the
month of March. Bakersfield received 2.01 inches of rain which was 66%
above average for March. Geoff Fulks, Cal Water District Manager
concurred with Mr. Chianello as Cal Water had similar percentages for
March 2019. Board information only, no action taken.
NEW BUSINESS
A. Amendment to Agreement with Sierra Snow Surveys to conduct snow
surveying
City Council approved Agreement # 18-186 with Sierra Snow Surveys in the
amount of $60,000 to perform snow measurements on thirteen (13) Kern
River snow courses in the southern Sierra Nevada mountain range. This
year being a wet year, Sierra Snow Surveys was requested to conduct an
additional measurement in May 2019. In addition to the cost of May 2019
snow surveying, a proposal was received from Sierra Snow Surveys to
perform February -April 2020 snow surveys for the some cost of $60,000. City
staff is proposing to amend the agreement with Siena Snow Surveys for
work performed in May 2019 and also to be performed in 2020 for an
amount not to exceed $80,000 and extend the contract through June 30,
2020. Chairman Smith inquired to how many times Sierra Snow Surveys
perform a measurement. John Ryan, Water Resources Superintendent
stated it is usually the last week of the months of February, March, and
April. Member Weir verified the cost and amount of agreement and asked
Mr. Chianello to have the amended amount exactly match the proposal.
Motion by Weir to refer amendment to agreement with discussed changes
to City Council. APPROVED ALL AYES, PARLIER ABSENT
8. WATER BOARD STATEMENTS
Chairman Smith inquired to the current amount of waterflowing in the Kern
River. Mr. Chavez reported 2,900 cubic feet per second (cfs) coming out
of Lake Isabella with flow downstream at Coffee Road of 1100 cfs with an
additional 200 cfs inflow of Friant Water.

/APPROVED
FROM: Art Chionello, Water Resources Manager DEPARTMENT HEAD 4�
DATE: July 5, 2019
SUBJECT: Update on Water Usage in the City's Domestic Water Service Area June
2019
RECOMMENDATION: For Board information
BACKGROUND: On April 7, 2017, the Governor ended the Drought State of Emergency
for California's water purveyors. Even though there is no longer a conservation target for
the City's Domestic Water Service Area, the City is still recommending that conservation
efforts by our residents continue due to historically low groundwater levels.
The graphs on the following page show the water usage for the City's Domestic Water
Service Area for 2019 to -date and the monthly percentage reduction for the service area
for the same period compared to 2013.
So far in 2019, the City's Domestic Water Service Area has saved 2,354 acre feet
compared to 2013 quantities. The cumulative water savings over this time period is about
13.75% reduction from 2013 quantities. The water savings amounts stated are for total
water deliveries in the system.
It should be noted that the City's Domestic Water System has grown over the past six
years. In 2013 the population served by the City domestic water system in June was
approximately 135,757 residents and in June 2019, the population served is about 153,358
residents. This is a population increase of about 11.5% over the six-year period. Therefore,
considering the population growth in the City's system and the reduced amount of water
used during the month of June, water use reduction equates to approximately 25.8% per
person per day.

SUBJECT:
Contract Change Order No. 1 to Agreement No.
17-084 with W.M. Lyles, ($245,596; revised
not to exceed $29,123,931) for the Construction and Design of TCP Project.
RECOMMENDATION: Staff recommends the Water Board refer the change order to City Council for
approval.
BACKGROUND: On July 18, 2017, the State Water Board adopted a new maximum contaminant level
(MCL) for the contaminant 1,2,3 - Trichloropropane (TCP) in groundwater. This new regulation
is applicable to drinking water served by public water systems, including the City's domestic water
system, and became effective January 1, 2018. In order to be in compliance with the new MCL, the City
began the TCP Mitigation Project June 28, 2017 by entering into a design/build contract (Agreement No.
17-084) with W.M. Lyles. The construction project was planned and sequenced so that water demands
and water quality compliance standards would always be met. As of June 26, 2019 the project was
deemed complete.
The project consisted of design and construction of treatment infrastructure for certain impacted wells
and also consisted of various critical improvements made to the domestic water system. The project
brought thirty-four (34) wells into compliance, converted an existing City owned agriculture well into a
domestic water well, added emergency generators to several well sites, and added electronic control
systems which improves operability of the wells.
During this project multiple changes to the original scope of work were needed. A detail description of
the changes made can be found in the attached Water Resources memo date June 14, 2019. A total of
twenty-one (21) extra work changes were made for an amount of $686,990.02 and a total of five (5)
adjustment of compensation changes (credits) were made for an amount of $441,394.02, making the net
change order amount $245,596.00. This final change order amount is less than 1 % of the construction
contract value. No General Fund dollars will be expended for this change order.

The following work is to be added to the scope of work defined in the contract
In order to continue the capability for the well at well site CBK-13 to fill Truxtun Lake, additional valves and
piping need to be installed at this well site. The contractor has agreed to do this work for the lump sum price
of $8,819.45.
At well site CBK-26, a tree needs to be removed in order to provide access to the new maintenance gate used
by cranes to pull the well head. The contractor has agreed to remove this tree for the lump sum price of
$4,581.36
The SCADA system at well site L-207 need to be upgraded to the latest model in order for it to be compatible
with the rest of the system and so that the automatic controls installed on this project can be utilized. The
contractor has agreed to do this work for the lump sum price of $18,378.89.
In order for the system at the Olcese 3 well site to operate properly, an additional "duck bill" valve needs to be
installed. The contractor has agreed to furnish and install this valve for the lump sum price of $3,950.07.
Work for this project needed to be time within the Union Pacific Railroad's (UPRR)right-of-way. During this
work, UPRR is requiring that additional safety flagging be done by their staff. The contractor has agreed to
accept a lump sum of $3,149.69 as reimbursement for this unforeseen expense.
During construction at well site CBK-14, it was discovered that the flow meter at this site was non-functional
and needs to be replaced. The vault housing this meter is also in disrepair and needs to be replaced. The
contractor has agreed to replace these facilities for the lump sum price of $21,845.31.
During construction, it was discovered that the 5 inch readout screens on the specified SCADA system are too
small for the maintenance crews to properly read and record data. As such, these screens need to be changed
to a 10 inch Graphite HMI screen. The contractor has agreed to do this upgrade for the lump sum price of
$29,370.29.
The conversion of the existing analog chart recorders to a digital recorder with HMI screen began during the
project which is an addition to the scope of work on this project. Several UNIT scream were purchased for this
conversion and the recorders were converted at 3 sites when it was discovered that the new SCADA system
will perform this monitoring and recording function. As such, the RMI screens that were purchased (and can
not be returned) were given to City Water Resources for use in future chart recorder conversions in for
SCADA installations that may become necessary. The contractor has agreed to accept a lump sum of
$90,27024 for the 3 site conversions and for the additional HMI screens provided to the City.
Due to the configuration of the new piping on the project well sites, the water lubrication system for the well
heads at the various well sites had to be modified so that the water source for this system provided constant
water pressure. The contractor has agreed to make these modifications for the lump sum price of $103,255.81.
During construction, it was discovered that the existing Granular Activated Carbon (GAC) vessels at well site
L-205 (which were originally to be removed) need to stay in place as part of the new system, thereby
necessitating a change in the piping and valving system at this site. This work also included the provision and
installation of several automated valves. The contractor has agreed to perform these modifications for the
lump sum price of $17,258.73.
Doing construction, it was discovered that at well site CBK-16, a new flow meter was needed to help monitor
the water flows at this well site. The contractor has agreed to provide and install the flow meter and the vault
needed to house the flow meter for the lump sum price of $25,157.99.
The station isolation water valve at well site CBK-23 was discovered to be significantly leaking thereby not
allowing the well site to be isolated from the water system. The contractor has agreed to remove and replace
this water valve for the lump sum price of $11,603.00.
During construction, it was requested that 3/4 inch crushed gravel be placed as site surfacing on the dirt
surfaces of well sites being constructed for this project. The contractor has agreed to place this gravel
surfacing for the lump sum price of $172,504.00.
Due to several delays on this project (7 month total delay), the time needed for quality control engineering
being supplied by the contractor as well as the total cost for this service increased. The contractor has agreed
to accept a lump sum of $76,356.00 to cover these quality control cost increases.
After the vessels arrived from Evoqua, it was discovered that the interior coating of most of the vessels was
damaged. As such, these vessels needed to be inspected and repaired by the manufacturer. During this
process, the contractor provided manpower for logistical support so these repairs could be done. The
contractor has agreed to accept a lump sum of $22,591.57 to supply this needed logistical support.
After the vessels supplied by Evoqua arrived and were installed, it was discovered that several small pipe
fittings and valves were broken or non-functional and need to be replaced. The contractor has agreed to
remove and replace these fittings for the lump sum price of $256.64.
During construction, the need for additional piping at well sites CBK-14 and L-201 was identified. This
additional piping is needed to in order to provide the capability of sending treated water to waste during the
sampling and testing to identify levels of TCP and other substances in the fully treated water. The contractor
has agreed to do this additional work for the lump sum price of $43,431.48
After the HPC carbon was instated a[ well sites CBK-14, 21, 41, and 47, it was discovered that the post treated
water contained high levels of iron oxide. An investigation of this issue showed the source of this iron oxide
to be the HPC carbon installed in the vessels at these sites. Consequently, this carbon was removed and
replaced with different carbon by the manufacturer. This operation also required logistical support from the
contractor. The contractor has agreed to accept a lump sum of $20,276.58 for providing the needed logistical
support.
Atter the chlorine feeds were installed at the various well sites as part of the new system, it was discovered that
these feeds needed to be relocated at the sites with existing arsenic treatment vessels so that the chlorine would
not damage the carbon in the arsenic vessels. The contractor has agreed to relocated the carbon feeds at these
sites for the lump sum of $10,337.64.
After installation of the generator at well site CBK-06, investigation of an electrical issue preventing the
variable frequency drive from properly working was performed. This issue was discovered to be an existing
problem with the site. The contractor has agreed to accept a lump sum of $1,636.20 for troubleshooting this
electrical issue. V
While trying to wine in the new Generator Controls at well site CBK-30, it was discovered that the some of the
existing wiring needed to perform this operation was deficient and needed to be repaired and reconfigured.
The contractor has agreed to correct this deficient wiring for the lump sum price of $1,959.08
The following work is to be deleted from the scope of work defined in the contract
The original scope of work called for the contractor to finish the construction of the arsenic treatment system
at well site CBK-26. This work was ultimately completed by others. As such, the contractor has agreed to
provide a credit in the amount of ($173,750.00) for deletion of this item from the scope of work.
The original scope of work required the installation of a SCADA system at well site CBK-26. This work will
now be completed by others. As such, the contractor has agreed to provide a credit in the amount of
($37,960.00) for deletion of this item from the scope of work.
The original plan called for the provision and installation of a bolted steel tank at well site CBK-19 for storage
of water used for backwashing the new GAC vessels. A redesign of this site was done and this bolted steel
tank is no longer required. As such, the contractor has agreed to provide a credit in the amount of
($92,675.84) for deletion of this item from the scope of work.
The original plan called for the provision and installation of a bolted steel tank at well site CBK43 for storage

tank is no longer required. As such, the contractor has agreed to provide a credit in the amount of
($92,675.84) for deletion of this hem from the scope of work.
The original contract called for the procurement and installation of a SCADA system (SCADA Pack 32) at the
various well sites being modified. During construction, it was discovered that a newer model of SCADA
system was needed and this system will be now provided by the City of Bakersfield for installation by the
contractor. As such, the contractor has agreed to provide a credit in the amount of ($44,332.34) for deletion of

Proposed increase to O&M Agreement No. 92-250 with California Water Service
Co., in the amount of 3.1 %, increasing annual costs by an estimated $224,698.
RECOMMENDATION: Staff recommends approval of proposed rate increase.
BACKGROUND: On November 4, 1992, the City entered into Agreement No. 92-250 with California
Water Service Co. (CWS) whereby CWS would operate and maintain the City's water system in
exchange for a set rate paid on each active City water connection. As allowed under terms of
the agreement, CWS may request annual increases to this rate.
The recent annual CWS increases are as follows.

CWS and the City have been in discussions to negotiate a rate adjustment to be effective
January 2019. After considering CPI and increased operation and maintenance costs associated
with City's installation of 110 new granular activated carbon vessels required to remove 1,2,3-
Trichloropropane (TCP) from the groundwater, staff recommends a monthly per meter fee
increase from $12.86 to $13.26 (3.10%).
CWS currently maintains approximately 46,812 active water connections. This rate adjustment
would increase annual O&M costs paid to CWS by approximately $224,698. Staff recommends
Water Board approve this rate increase. Payment would be made out of Water Resources
Department's FY 2018-19 and FY 2019-20 Operating Budget. The proposed increase to this
operations and maintenance contract will not chance the water user rates for the City of
Bakersfield's domestic water system.

Consumer Price Index, Los Angeles area—January 2019
Area prices were up 0.7 percent over the past month, up 3.2 percent from a year ago
Prices in the Los Angeles area, as measured by the Consumer Price Index for All Urban Consumers (CPI -
U), advanced 0.7 percent in January, the U.S. Bureau of Labor Statistics reported today. (See table A.)
Assistant Commissioner for Regional Operations Richard Holden noted that the January increase was
influenced by higher prices for shelter and apparel. (Data in this report are not seasonally adjusted.
Accordingly, month-to-month changes may reflect seasonal influences.)
Over the last 12 months, the CPI -U rose 3.2 percent. (See chart I and table A.) Energy prices advanced 2.5
percent, largely the result of an increase in the price of natural gas service. The index for all items less food
and energy advanced 3.4 percent over the year. (See table 1.)

DEPARTMENT HEAD
APPROVED
Approval of a resolution is required to utilize the design/build construction
procurement process.
Staff recommends the Water Board refer the Resolution to City Council for
approval.
BACKGROUND: On May 23rd, 2018 council approved a resolution authorizing the Water
Resources Manager to apply for the Water and Energy Efficiency WaterSMART Program
administered by the United States Bureau of Reclamation for a SCADA project. Water
Department has applied and has received confirmation of grant funds.
The proposed SCADA system will provide real-time continuous monitoring of river water flows and
allows for data to be archived. This project would install SCADA at approximately 20 points along
the Kern River. This will allow for remote monitoring of water delivery conditions (flow rates, water
elevations, control device openings, etc.). Furthermore, it should be noted that a state mandate
(SB 88) requires SCADA installation by the end of calendar year 2020.
The most efficient and cost effective approach for design and construction to install the SCADA
system is the design/build project delivery method (Similar to the recent TCP mitigation project).
Approval of a resolution is required to utilize the design/build construction procurement process.
Municipal Code 3.20.060 D. 5 requires that a resolution be approved by City Council prior to util'ving
the design/build process. Staff recommends the City Council adopt the resolution. There will be
no General Fund associated with this resolution.
