recommendations.
ITEM EXPLANATION:
On March 14, 1989, City Council approved the sale of bonds to finance (
share of the Encina Water Pollution Control Facility Phase N Expansion Pro financing plan obligates Carlsbad to make yearly payments on the pr&
interest on the bonds. Wilson Engineering has completed an update to the 1 1987 Master Plan of Sewerage which examines the impacts of these yearly I on the City's Sewer Construction Fund. The update indicates that a Sewer
Fee of $1,610 is needed to provide revenues necessary for making the yearly I
and constructing improvements to the City's wastewater facilities required at
The fee will be adjusted yearly according to the Engineering News Record Lo!
Construction Cost Index (ENR-LA-CCI) .
Revenue from Sewer Capacity Fees may not be utilized to construct collection
for new developments. In most cases, developers are required to bui
conveyance systems. Another study by Wilson Engineering provides recornme
for establishing Sewer Benefit Area Boundaries and Fees. The fees will be UI
reimburse developers for constructing the collection facilities necessary for :
properties within each Benefit Area as required by the City's Growth Man
Program. These fees will also be revised yearly according to the ENR-LA-C(
ENVIRONMENTAL IMPACX:
A Negative Declaration finding that no environmental impact will occur as a
the increase in Sewer Capacity Fees and establishment of the Benefit Area 1

CHAPTER 1
INTRODUCTION
In 1989, the City of Carlsbad elected to bond finance their portion of the Phase
IV construction at the Encina Water Pollution Control Facility. These bonds
obligate the City of Carlsbad to pay back principle and interest in future years.
The purpose of this report is to analyze the impact of these future bond
payments and other cost increases and adjustments on the sewer connection
fees. I
The assumptions used for determining future flows are derived from the
December 1987, Master Plan of Sewerage. Sizing the facility and cost data are
obtained from the December 1987, Master Plan of Sewerage and the 1989-90
Encina Budget. All cost data has been revised to an ENR-CCI-LA of 5,800.
RECOMMENDATIONS
1. The City wide capacity fee should be changed to $1,610.
2. The City wide capacity fee should only cover costs for the Encina Water
Pollution Control Facility, the Vista/Carlsbad Interceptor, and the Home
Plant Pump Station.
3. A number of smaller sewer area fees should be established to fund
collection system improvements to bring a sewer line to each zone
subbasin as defined in the December, 1987, Master Plan of Sewerage and
the Benefit Area Fee for Conveyance System Improvements dated March
1930.

CHAPTER 2
CAPITAL COSTS
All capital costs are based on information presented in the December 1987
Master Plan of Sewerage and the Encina Water Pollution Control Facility 1989-9C
Budget. All costs have been increased to reflect an ENR-CCI-LA of 5,800.
ENCINA WATER POLLUTION CONTROL FACILITY COSTS
Table 2-1 presents a summary of the City of Carlsbad share of improvements tc
the Encina Water Pollution Control Facility over the next 30 years. The total
costs of these improvements is estimated to be $43,573,000.
Phase IV Project
Construction is currently underway on the Phase IV project. During the Phase
IV project, the City of Carlsbad’s ownership in the plant will change. Because
the City of Carlsbad’s ownership in the plant is changing, its share of project
costs will not be established until construction is completed. We are estimating
that the City of Carlsbad’s share in the Phase IV plant and outfall projects will be
23.5 percent. The Phase IV operations building improvements have not been
designed or constructed. The City of Carlsbad’s share in the operations building
improvements project will be based on their post-Phase IV ownership of 25.68
percent. The Phase IV operations building construction is scheduled to begin
near the end of the Phase IV plant and outfall projects.

Phase V
The Phase V project will not occur until after the year 2000. For the purpose c
establishing capacity fees we are estimating it will occur in approximately th
year 2005. The City of Carlsbad’s share in this project will be based on the
needed capacity. Our cost estimate is based on the City of Carlsbad obtainin!
an additional treatment capacity of 5.09 million gallons per day during the Phasi
V project.
Solids Manaaement -
The solids management project will be done in two stages. The City c
Carlsbad’s share of the solids management project will be 24.19 percent. Wr
have estimated the cost of land acquisition for this project at $5,000,000.

Ocean Outfall
The City of Carlsbad’s share of future ocean outfall costs will be 24.19 percenl
For the purposes of estimating capacity fees, a reballasting project is schedule1
for the year 1993. A parallel ocean outfall will have to be built in conjunction wit
the Phase V expansion project and it is also scheduled for the year 2005.
VISTA/CARLSBAD INTERCEPTOR
Table 2-2 provides a list of improvements needed to .the Vista/Carlsbac
Interceptor. The total estimated cost for these improvements is $6,863,000
Exhibit A from the December 1987, Master Plan of Sewerage shows the locatior
of the reaches called out in Table 2-2. This exhibit is found in the pocket in the
back of this report.
OTHER CITY OF CARLSBAD CAPITAL PROJECTS
Table 2-3 lists the other City of Carlsbad capital projects included in the City
wide capacity fee. The projects total $1,137,000 and include the Home Plant Lift
Station and Force Main improvements.
In addition to these specific City of Carlsbad improvements, we have included
a category for miscellaneous Gity of Garlsbad capital improvement projects,
which is factored into the City wide capacity fee. The projected estimate of
costs for the miscellaneous projects is $70,000 for each year through the year
2020.

CHAPTER 3
CITY WIDE CAPACITY FEE
In order to assess the impact of bond payments on the sewer construction fund
a year by year cash flow projection is needed. This year by year projection mus
include estimated number of units, inflation rates and interest.
UNITS
On December 29, 1989, the City of Carlsbad had a total of 26,995 equivalen
dwelling units. The December 1987, Master Plan of Sewerage projects, at builc
out, that the City will have a total of 60,935 equivalent dwelling units. For thc
purpose of our capacity fee cash flow analysis, we have assumed that the Citl of Carlsbad will build out in the year 2020. We have uniformly distributed thc
dwelling units each year. Thus, for the years 1990 through 2019, 1,09!
equivalent dwelling units per year are assumed to be connected and in the finz
year of the projection 1,090 units are assumed to be connected to total 60,93!
equivalent dwelling units.
Bond Pavments
Bond payments for the Phase IV bonds are approximately $850,000 for the firs
three years from 1990 to 1992, and $1 ,I 20,000 for the remaining 22 years of thl
bond issuance. This bond payment provides $1 1,029,000 for the constructiol
of the Encina Phase IV projects. These same ratios were utilized for a projectel
bond issuance in the year 2005 to cover the year 2005 expenses. Based on l
total construction cost need of $53,853,000, bond payments for the year 2OOl
through 2007 will be $4,150,000. For the remaining 22 years, bond payment
will be $5,469,000.
INFLATION AND INTEREST
Construction costs were projected to increase 5 percent per year. Interes
income on the sewer construction fund was estimated to be 8 percent per year

SEWER CONSTRUCTION FUND OBLIGATIONS
Table 3-1 provides a summary of the expenses to the sewer construction fund.
The expenses include construction, bond payments and the Lake Calavera Hilk
Water Reclamation Plant credit. The City of Carlsbad is obligated by contrac:
to provide connection fee credits for the Lake Calavera Hills area. These credit:
decrease the income to the sewer construction fund and show up as an expense
on this table.
ESTIMATED FEES
Table 3-2 shows a cash flow projection year by year needed to obtain a zerc
balance in the year 2029, and cover all estimated construction costs, bonc
payments and credits. In order for the sewer construction fund to have a zerc
balance in the year 2029, the present sewer connection fees should be changec
to $1,610.

CHAPTER 1
INTRODUCTION
The City of Carlsbad sewer capacity fee includes improvements to the Encina
Water Pollution Control Facility, the Vista/Carlsbad Interceptor, the Lake
Calavera Hills Water Reclamation Plant and the Home Plant Lift Station.
Construction of the facilities funded by the city wide capacity fee does not
provide a sewer line to each of the City’s growth management zones. Thus
there are a number of conveyance facilities which will need to be funded by more
than one growth management zone. This report provides recommended
boundaries for benefit areas for facilities recommended in the December, 1987
Master Plan of Sewerage. In most cases these facilities will probably be built by
a developer. This developer will then be eligible for reimbursement by
subsequent developers within the benefit areas established in this report.
Reimbursement fees for the Occidental/Ponto Trunk and Ayres/Batiquitos Trunk
have also been included.
RECOMMENDATIONS
1. Adopt the benefit areas A through M and establish an estimated cost per
unit for development of the conveyance system in these benefit areas as
presented in Table 1-1.

SUMMARY OF CHANGES
1. Provide a second fee above the city wide capacity fee to fund conveyance
system improvements.
2. Provide a fee based system for the construction or reimbursement for
construction of conveyance systems to each subbasin established in the
December, 1987 Master Plan of Sewerage.

CHAPTER 2
FEE AREAS
All costs presented in this report are based on facilities recommended in tht
December, 1987 Master Plan of Sewerage. Costs for these facilities have beer
increased based on an ENR-CCI-LA of 5,800. Where better data is currentl!
available on facility costs, other adjustments have been made. The number o
units in each subbasin is also based on information presented in the December
1987 Master Plan of Sewerage. Unit counts have been updated to reflect curren
development status and projections.
Figure 2-1 shows the boundaries of the recommended fee areas. Exhibit A fron
the December, 1987 Master Plan of Sewerage may be found in the pocket at thc
back of this report and shows the location of the reach designations called ou
in the tables in this chapter.
