I AND APPROPRIATION OF FUNDS
RECOMMENDED ACTION:
City of Carlsbad City Council: Adopt Resolution No. 2002-144 authorizing the execution
of Amendment No. 1 to the professional services agreement for engineering services to update the
Carlsbad Sewer Master Plan with Dudek and Associates, Inc., and the appropriation of Sewer Connection Funds for Project No. 3870.
Carlsbad Municipal Water District Board of Directors: Adopt Resolution No. 1150
authorizing the execution of Amendment No. 1 to the professional services agreement for
engineering services to update the Carlsbad Water Master Plan with Dudek and Associates, Inc.,
and the appropriation of Water Connection and Replacement Funds for Project No. 3870.
ITEM EXPLANATION:
On December 18, 2001, the City Council adopted Resolution No. 2001-378 and the Board of
Directors of the Carlsbad Municipal Water District adopted Resolution No. 1135 authorizing the execution of a professional services agreement with Dudek and Associates, Inc., for the update to
both the Carlsbad Sewer and Water Master Plans. The updated Master Plans will identify future
sewer and water facility needs to ensure conformance with Growth Management Performance
Standards through buildout of the City.
The first phase of this project required the review and analysis of the current Sewer and Water
Master Plans and supporting technical data. This exercise was necessary to prepare a “gap”
analysis resulting in the identification of missing or outdated information. Based on this review,
additional tasks are necessary in order to allow for the full adoption of the final Water and Sewer Master Plan documents. The following is a brief description of the additional tasks:
0 Sewer and Water Connection Fee - The existing connections fees are based on the 1990 Water Master Plan and the 1992 Sewer Master Plan. Since that time, future
that adequate funds will be available to pay for the cost of future master plan facilities, infrastructure needs have changed and construction costs have risen. In order to guarantee
a complete update of the connections fees are necessary.
0 Alternative Water Supply - The San Diego County Water Authority is considering
construction of a water desalination facility in Carlsbad to provide potable water for the
region. Staff feels there is a need to evaluate the City’s existing and future water
This analysis will evaluate the water piping and pumping requirements to utilize this
infrastructure system analyzing the operational impacts of an alternative water supply.
alternative source of potable water.
0 H20Net Water Model Update - An H20Net Water Model of the CMWD distribution system
was developed as part of a previous Water Master Plan update. Since that time, a number of new waterlines have been constructed. Amendment No. 1 includes a task to update the existing water model by including the additional waterlines.

ENVIRONMENTAL REVIEW
The Planning Director has determined that the update to both the Sewer and Water Master Plans
will require the adoption of a Program Environmental Impact Report (PEIR). This determination is
due to the need to identify the potential environmental impacts of future sewer and water lines. In
addition, the PEIR will be required since staff expects that water connection fees will be adjusted to
reflect updated construction costs. The additional tasks outlined in the contract amendment will
cover the requirements tasks for adoption of the Sewer and Water Master Plans.
FISCAL IMPACT:
The original professional services agreement approved in December 2001 appropriated a total of
for the update to both the Carlsbad Sewer and Water Master Plans. Funding was provided by a
$407,215 in order to fund the professional services agreement with Dudek and Associates, Inc.,
combination of Sewer and Water Connection and Replacement Funds.
The additional tasks outlined in Amendment No. 1 are estimated to cost $86,885. Staff is

SCOPE OF WORK FOR ADDITIONAL ENGINEERING CONSULTING SERVICES
CITY OF CARLSBAD SEWER AND WATER MASTER PLAN UPDATES
April 25,2002
Additional services for the Carlsbad Water and Sewer Master Plan Updates are identified for 1)
an analysis of water distribution from a proposed desalinization facility at the Encina Power
Plant 2) revisions to the 2001 H20NET model and 3) a sewer and water connection fee update.
BACKGROUND
Desalinization Water Supply Alternative
A fhre 50 MGD desalinization facility may be located adjacent to the Encina Power Plant. The
desalinization plant would deliver water to the Carlsbad Municipal Water District (CMWD),
City of Oceanside, Vista Irrigation District, Vallecitos Water District and the San Diego County
Water Authority (SDCWA). Under the current supply scenario identified in a feasibility study
prepared by Poseidon Resources (Poseidon Study), a constant supply of 10 MGD will be
provided to CMWD. This supply rate is the approximate minimum month demand of the
District.
Desalinated water will be pumped.to the 195 MG Maerkle Dam and then the Maerkle Reservoir,
where it will enter the CMWD distribution system. During minimum demand months, CMWD
will be supplied entirely from desalinated water from Maerkle Reservoir and the Tap
Connection. Pumping will be required to supply desalinated water from Maerkle to portions of
the distribution system now supplied by gravity from Aqueduct Connections 1 and 2. During
higher demand periods, water supply will be a mix of desalinated and imported water. Under
these conditions the distribution system should be operated to maximize the gravity supply and
minimize pumping.
The professional services outlined in the scope of services are recommended to identify
additional facilities and operating scenarios required for effective utilization of desalinated water.
According to the Poseidon Study, a desalinization facility could be operational as soon as 2006.
Hydraulic modeling performed in the Water Master Plan Update is based on' existing and
ultimate conditions. It is proposed that the existing system model be used to evaluate the
distribution of desalinized water. The results of the desalinated water supply analysis will be
documented in the Water Mater Plan Update currently being prepared by Dudek.
Sewer and Water Maser Plan Additional Services Page I of 7
Revisions to 2001 H20NET Model
An HzONET model of the CMWD distribution system was developed as part of the 1997 Master
Plan Update. In 2001 a different consulting firm updated the model by adding pipelines and
control valves constructed up to October 2000. The current scope for the 2002 Water Master
Plan Update is based on updating the 2001 model with the addition of new facilities constructed
through July 2001.
Upon review of the 2001 model, it was discovered that additional pipelines and facilities would
need to be added. The professional services outlined below are recommended to revise and
enhance the 2001 model before it can be used for the 2002 Master Plan hydraulic and water
quality analysis. An additional task has also been included to add facilities constructed between
July 2001 and January 2002.
Connection Fee Update
The City of Carlsbad wants to update their existing connection fees based on revised buildout
projections and the inclusion of CIP projects that will be identified in the Water and Sewer
Master Plan Updates. Carol10 Engineers prepared the previous connection fee update, which
was documented in a draft report dated March 2000. The connection fees were based on
projected growth calculations made in FY1999/2000 and CIP projects identified in the 1997
Master Plans. An update of this analysis is proposed to recommend new connection fees that
will generate sufficient revenue to pay for the planned capital improvements identified in the
current Water and Sewer Master Plan Updates, now being performed by Dudek & Associates.
Future water demands and sewer flows will be estimated using projected EDUs based on the
City of Carlsbad’s recently compiled database. of buildout projections. In the previous
connection fee study, water and recycled water were considered as a single resource. Recycled
water demands and project costs will not be revised in this proposed update, and Phased I1
recycled water distribution and treatment costs identified in the previous connection fee analysis
will be assumed. The professional services outlined in Section C below are the additional
services recommended for the Master Plan Updates to provide an update of water/recycled water
and sewer connection fees.
I. SCOPE OF SERVICES
Based on our current understanding of the Project, Dudek & Associates, Inc. (Jhdek) will provide
the following engineering services:
A. Desalinization Water Supply Alternative
1. REVIEW OF REFERENCE MATERIALS. Previous feasibility and planning studies
will be reviewed to obtain desalinized water supply assumptions and modeling
methodologies.
Sewer and Water Maser Plan Additional Services Page 2 of 7
2. IDENTIFY PRESSURE ZONE SERVICE AREAS. Based on a desalinized water
supply rate of 10 MG and existing and projected demands for each pressures zone,
identify the pressure zones that would be supplied with desalinized water under 1)
existing minimum and maximum day demands, and 2) ultimate minimum and
maximum day demands. Pressure zones supplied with desalinated water will be
identified to minimize pumping and sizing of additional facilities. Figures andor
schematics will be prepared to illustrate the areas served by desalinized and imported
supplies.
3. RE-EVALUATE 10-DAY STORAGE REQUIREMENT. The CMWD has adopted a
policy to provide 10 days of storage within the District for use in emergency
conditions. Consider the impact of a future desalinated water supply on potential
emergency scenarios, and recommend modifications to this policy, as appropriate.
Re-calculate the volume of required emergency storage based on ultimate demand
projections with a desalinated water supply.
4. IDENTIFY AND SIZE NEW PUMP STATIONSPIPELINES. Estimate the volume
of desalinated water that will need to be pumped from Maerkle to higher zones now
supplied from Aqueduct Connections 1 and 2. Determine the maximum pumped
supply rate and annual pumped flow. Separate pump stations to the 700 and 550
Zones are assumed. Size new pump stations and pipelines considering both the supply
of desalinated water under normal conditions, and supply from Maerkle under an
emergency scenario. Investigate supply of the 550 Zone from the 490 Zone during
low demand periods to reduce pumping.
5. VERIFY PUMP STATION OPERATIONS. The HzONET existing system model
developed in the Water Mater Plan Update will be modified to analyze supply of
desalinated water. New pump stations and pipelines will be added to the existing
model to distribute desalinized water from Maerkle Reservoir to the 700 and 550
Zones. An extended period analysis will be performed to verify pipeline sizes and
filling of the Santa Fe I1 and La Costa Hi Reservoirs without supply from the
Aqueduct Connections. The system will also be analyzed with a water supply to the
550 Zone at a reduced grade from the 490 Zone. Any required upsizing of pressure
reducing stations or valving changes will be identified. Hydraulic analyses will be
preformed with the existing system model only, as the size of the required desalinized
water distribution facilities are not expected to change in the ultimate system.
6. PERFORM AGE-OF-WATER SIMULATIONS. A change in supply patterns can
significantly impact water circulation and resulting water quality. This may be most
apparent in reservoirs that normally supply imported water, which will be at the “end”
of the water supply system with a desalinized water supply. An age-of-water
simulation will be performed with the modified existing system model to identify any
general areas of reduced circulation and significant lengths of dead-end or non-
circulating pipeline within the 700 and 580 Zones. Recommendations will be made
Sewer and Water Maser Plan Additional Services Page 3 of 7
for revised operational settings (PRV settings, lower water reservoir levels, supply
locations, etc) to improve water circulation during low demand periods.
7. RECOMMENDED FACILITY AND OPERATIONAL IMPROVEMENTS.
Changes to the recommended CIP projects as a result of a desalinized water supply
will be identified and summarized in a table. . New CIP projects will be identified and sized, including pipelines, pump stations
and improvements to existing pressure reducing stations. There are several
projects in the current CMWD CIP that were identified to supply water from
Maerkle Reservoir in the event of an emergency. Any required modifications to
these projects for the supply of desalinated water will be identified.
Current CIP projects that can be eliminated as a result of desalinized water will be
identified. This may include the downsizing or elimination of projects required to
provide 10 days of emergency storage.
Recommended operational procedures to reduce water residence. time in the
distribution system and reservoirs will be summarized.
Pump Stations - Major features of the required pump stations will be documented
in a table.
CIP project cost estimates will be developed. Project costs for the desalinized
water supply alternative will be compared to the current CIP and presented in
terms of the additional or reduced costs. Annual energy costs will be estimated
based on the required pumping of desalinated water to the 700 and 550 Zones.
8. DOCUMENTATION OF RESULTS. Documentation of analysis assumptions,
methodologies and results will be included as a separate report chapter in the draft
and final Water Master Plan Update report. Computer models and output results will
also be provided on a CD-ROM.
9. MEETINGS. Prepare for and attend one meeting with the City to define the proposed
project and discuss analysis assumptions, criteria and proposed system operations.
B. Modifications to 2001 H20NET Model
1. ADJUST PIPELINE LOCATIONS. Dudek has converted the 2001 Model from
NAD 27 to NAD 83 coordinates and overlaid the pipelines on a SANGIS parcel map.
The pipelines added as part of the 2001 update were not digitized to these
coordinates. The pipelines will be moved based on the alignments from as-built
drawings.
Sewer and Water Maser Plan Additional Services Page 4 of 7
2. VERIFY AND MODIFY TIE-IN LOCATIONS. Pressure zones boundaries in some
of the newer areas have been expanded and modified. All 2001 pipeline connections
to the 1997 model will be reviewed and modified as necessary.
3. MODIFY PRESSURE CONTROL VALVES. Pressure reducing stations (PRVs) in
the 2001 model were modified fiom the 1997 model to include a parallel pressure
sustaining valve (PSV). A combination PRVPSV can be modeled this way in
HzONET using logic controls, but this greatly adds to the complexity of the model
and can often result in the model not being able to converge upon a solution. City
Operations Staff have stated that most of the PSVs only operate under emergency
conditions. Dudek will meet with Operation’s staff to determine the normal operation
of the pressure control valves, and simplify the model accordingly. Output results
can be checked to determine if a PSV would operate, and valves can be added back
individually on an as-needed basis. This simplification is necessary to perform an
age-of-water analysis, which will simulate the performance of the distribution system
over a period of two weeks or longer.
4. ADD PIPELINE INFORMATION. The 1997 model includes the construction year,
pipeline material, and pressure zone information for each pipeline segment. This
information was not included in the 2001 model updates. Dudek will add this
information to the new pipelines.
5. ADD NEW FACILITIES. Add or modify pipelines, control valves and other water
facilities based on improvements or additions to the water system constructed
between July 2001 and January 2002.
C. Sewer and Water Connection Fee Update
1. REVIEW OF REFERENCE MATERIALS. The previous connection fee update
report will be reviewed to obtain an understanding of the analysis assumptions and
modeling methodologies. Other available financial data will be reviewed to develop
an understanding of the City’s current financial situation and the basis of current cash
balances.
2. ’ PROJECT KICK-OFF MEETING. Prepare for and attend one project kick-off
meeting with the Project Manager and representatives of the finance and planning
departments staff to review the scope of work, identify key issues or concerns, obtain
population growth curves, and discuss the project schedule.
3. SEWER CONNECTION FEES
Calculate the number of projected sewer EDUs per each quadrant of the sewer
service area and summarize in a table. A sewer EDU was based on a wastewater
discharge rate of 220 gallons per day in the previous connection fee study. This
unit discharge rate may be revised with the current Master Plan analysis.
Sewer and Water Maser Plan Additional Services Page 5 of 7
Incorporate updated costs (provided by the City) for capital improvements and
expansions to the Encina Water Pollution Control Facility based on Carlsbad’s
current ownership.
Incorporate updated costs (provided by the City) for improvements to the
VistdCarlsbad Interceptor based Carlsbad’s capacity rights.
Add, delete or modify CIP projects as a result of the Master Plan analysis.
Update the available cash balance based on Fiscal Year 2001/2002 data.
Calculate the connection fee cost per EDU and summarize in a table.
Prepare a phasing timetable for the sewer Capital Improvement Program.
Perform a cash flow analysis over a 25-year period using the calculated
connection fee.
4. WATER CONNECTION FEES. Water and recycled water were considered as a
single resource and system in the previous connection fee analysis, and the water
connection fee recovers the cost for both potable and recycled water projects. For
this connection fee update the recycled water projections and CIP projects are
assumed unchanged, and only the potable water portion of the connection fee will be
updated. Separate water connection fees will be calculated based on the following
potential scenarios: 1)’future water system without facilities to provide 10 days of
emergency storage, and 2) future water system with fac.ilities to provide 10 days of
emergency storage.
Calculate the number of projected water EDUs per each quadrant of the water
service area and summarize in a table. In the previous connection fee update, an
EDU was defined as the equivalent of the water use for a 5/8 inch meter, which
was based on an average water consumption rate of 0.39 acre-feet per year. The
unit demand per water EDU may be revised with the current Master Plan analysis.
Add, delete or modify CIP projects as a result of the Master Plan analysis based
on the three potential potable water supply and distribution scenarios. Combine
recycled water and potable water project costs.
Update the available cash balance based on Fiscal Year 2001/2002 data.
Calculate the connection fee costs per EDU for each scenario and summarize in a
table.
Sewer and Water Maser Plan Additional Services Page 6 of 7
Prepare a phasing timetable for the water Capital Improvement Program for each
scenario.
Perform a cash flow analysis over a 25-year period using the calculated
connection fees.
5. DOCUMENTATION OF RESULTS. Documentation of analysis assumptions,
methodologies and results will be included as separate report chapters in the final
Water and Sewer Master Plan Update reports.
