F.'� CUTIVE SUMMARY
r In June of 1987, the Tbxas Legislature adopted Senate Bill 336 to standardize the method
by which political subdivisions recover the cost of capital improvements required to serve
new development. The legislation set forth a deadline and a methodology for the
calculation of the fees. In June of 1990, the City of Coppell adopted Water and
Wastewater Impact Fees which complied with the legislation. In 1991 and in 1994, the
City Council authorized the re- evaluation of these fees. As in the initial study, this study
area encompasses all land within the city limits.
�., The legislation requires that impact fees be based on an Equivalent Service Unit basis.
For the City of Coppell, one Equivalent Service Unit (ESU) has been established as a
5/8 "x3 /4" meter. There is projected to be $7, 511,000 of recoverable capital expenditures
for the water system and an estimated $6,981,000 recoverable from the City wastewater
system. This yields a maximum calculated water impact fee of $566 /ESU for water and
$599 /ESU for the City wastewater system.
If growth matched projections, adequate capital would be recovered to meet 100 % of the
fiscal requirements without the need for outside financing. however, growth rarely
matches projections and the capital projects must be constructed in advance of the
growth. As such, the City must incur long term debt for the construction of the projects.
The associated revenue bonds are secured through the water and wastewater rates. In
the first few years after the bonds are sold, the existing system customers, as well as the
first "new" customers support the burden of this debt service. This could subject the
City to a claim of double charging the new customers since they have paid an impact fee
covering the projects and paid rates supporting the associated debt service. There are
two possible solutions to prevent this type of claim. The first would be a two tiered rate
structure, one with and one without the associated debt. Aside from being an
administrative burden, such a rate structure could make future revenue bonds difficult to
market. The most realistic alternative is to discount the assessed impact fee, thus
assuring the City that a potential double charge does not occur since the new
development only pays the discounted portion up front with the unassessed balance being
recovered system wide through the rates. Therefore, we recommend the Council set the
new impact fee rates for 5/8 "x3/4" meters as follows:
Water Customers = $450
r-
Wastewater Customers = $450

OVERVIEW
Definition
Impact Fees are a charge or assessment imposed by a political subdivision against new
r developments in order to generate revenue for recouping or funding the costs of capital
improvements necessitated by and attributable to such new development. An Impact Fee
is not a tax. The fees cover a defined group of capital improvements and are allocated
equally over the anticipated new service units. The Impact Fee represents the equitable
recovery of actual and anticipated capital expenditures on a unit basis over a ten year
forward period. Projected expenditures beyond the ten year period, or expenditures to
serve existing development, are equally absorbed by all customers of the system.
By law, the Impact Fees may only be used to recover the cost of capital improvements
or facility expansions (contained in the approved Capital Improvements Plan) including
the construction contract price, surveying and engineering fees, land acquisition costs
(including court awards, attorney's and witness fees), and fees paid for preparing or
updated the Capital Improvements Plan. Impact Fees may not be used for parks or park
land acquisition; onsite water distribution, wastewater collection, or drainage facilities;
streets, sidewalks or other such facilities required by valid ordinances. Projected interest
charges and finance costs may be included in determining the amount of impact fees,
provided such fees are used for the payment of obligations for the construction of
facilities identified in the Capital Improvements Plan. Upon completion of a project, the
actual cost must be used to recalculate the fees to determine if refund provisions apply.
Methodology
The City of Coppell continues to be a rapidly growing community in northwest Dallas
t ' County. The City has grown from a population of 3,836 in 1980 to an estimated 21,600
in 1994. Approximately 35 % of the gross acreage within the City is currently
undeveloped; therefore, adequate land exists for the growth to continue throughout the
next ten year planning period. Employment growth is expected to be a substantial
component of the future growth as the western portion of the City begins to develop.
The legislation allows for the City to recover the cost of certain existing oversized
facilities as well as future facilities identified in the Capital Improvements Plan. lb
accomplish this, all water and wastewater facilities constructed with City funds were
analyzed for excess capacity. Table 1 summarizes the existing oversized projects eligible
for impact fee recovery. The total recoverable cost from future development for existing
wastewater facilities is $248,406.
The next step was to identify the capital water /wastewater projects and/or system
improvements which would be required to serve new development prior to January 1,
2004. The Ten Year Capital Improvements Programs contained in the recently adopted
Page 2
r
i
r
Water Distribution System Master Plan and Wastewater Collection System Master Plan
for the City of Coppell were evaluated for the ability to serve the anticipated new
development. The majority of the proposed improvements will be required in the
business /industrial districts in the western part of the city. For the purpose of this
analysis, it is assumed that developers will bear the cost of all infrastructure for their
development without City cost participation. The estimated recoverable cost for
proposed future water facilities (Table 2) is $7,511,646. Table 3 summarizes the
wastewater facilities which will be required prior to January 1, 2004 and the associated
recoverable costs. The estimated recoverable cost of the proposed wastewater facilities
is $6,733,009. Portions of the project cost were allocated between the existing and
proposed developments.
Future flows and system demands were calculated based on the existing flow data,
population projections, and the Future Land Use Assumption Plan provided by the City
of Coppell.
WATER SYSTEM ANALYSIS
.- Water usage within the City of Coppell has increased as dramatically as the population.
The average daily demand has increased from 0.602 MGD in 1980 to 3.83 MGD in
1993. In 1993, the water system experienced a new record high peak day of 12.72 MG.
Based on the population projections and the Future Land Use Assumption Plan, it is
estimated that peak day water demands will exceed 30 MGD by the year 2004 and
Ultimately approach 38 MGD at "build out ".
One of the most critical factors affecting water demands is weather. The amount of
rainfall and summer heat can significantly influence water usage. In order to assure a
dependable water supply for the community, the system must be capable of meeting the
expected peak hour demand during the peak day of a drought year Adequate fire
reserves must be maintained at all times. Summarized below are the past and projected
water demands:

MAX 4UM ALLOWABLE WATER SYSTEM DAPACT FEE
The legislation requires impact fees to be based on equivalent service units (ESU) to
insure an equal distribution between residential and employment development. The
standard residential water meter in the City of Coppell is a 5/8 "x3/4" meter. Therefore,
impact fee calculations were based on a 5/8 "x3 /4" meter = 1 ESU All other meter
sizes in the system were converted to ESU's using the factors published by the Texas
Rural Water Association (Table 4). Table 5 is a summary of the existing meters in the
water system with the corresponding ESU's. All meters including irrigation meters and
fire meters were included since these meters impose a significant potential demand on
the water system.
For the purpose of computing impact fees, a service unit has been defined as a single
family residence equipped with a 5/8 "x3/4" meter and will consume 437 gallons per day
Page 4
on the average. Based on this definition them will be 13,248.9 additional equivalent
water service units by the year 2004. The number of equivalent water service units for
r each land use type are presented below:
10 -YEAR ADDITIONAL EQUIVALENT WATER SERVICE UNTIE
The impact fee per ESU is calculated as the 10 -year system costs divided by the number
of new ESU's projected over the next 10 years or:
Impact Fee per Service Unit = 10 -year Costs (From Thble 2)
10 -year ESU's
$7.511.646
13,248.9 ESU's
= $566.96/ESU
The maximum impact fee which could be assessed for other meter sizes can be computed
by multiplying the number of 5/8 "x3 /4" meters equivalent to another meter size by the
impact fee per 5/8 "x3/4" meter.
'Eable 6 presents the recommended water system impact fees which could be assessed by
the City. The City Council may determine an amount to be assessed up to the
maximum, following the public hearing process.

WASTEWATER SYSTEM ANALYSIS
Wastewater flows within the City of Coppell have out -paced the rapid population growth.
The average daily flow has increased from 0.912 MGD in 1985 to 3.262 MGD in 1993.
Based on the population projections and Future Land Use Assumptions, it is estimated
that future peak wastewater flows will exceed 22 MGD by the year 2004 and 25 MGD
by 2014.
r Wastewater flows are highly dependent upon rainfall and the associated infiltration and
inflow. In 1988, the wastewater system flow averaged 52% of the average daily water
demand. In 1992, a year with above average rainfall, the wastewater system flow
averaged 108 % of the average daily water demand. This figure shows the large amount
of known Inflow and Infiltration which the system received. In order for the system to
r .. operate effectively, the wastewater collection system must be capable of handling peak
hourly flow events without overflow.

WASTEWATER SYSTEM CAPITAL D4PROVEIVIENT PLAN
rr The wastewater system was analyzed to determine existing capacities and projected flows
for the entire City. Average and peak demands were calculated based on the population
projections. The demands were distributed within the basins to the appropriate
interceptors. The process was repeated for the projected years 2004 and 2014 demands.
A series of system improvements were analyzed for each time period to size the ultimate
facilities and determine the size required for the year 2004. lkble 3 summarizes the
capital projects required to handle the year 2004 flows. The oversized existing lines and
future system improvements which were identified to meet the, projected year 2004
demands are as follows:

ALLOWABLE WASTEWATER SYSTEM EWPACT FEE
The legislation requires that impact fees be based on equivalent service units (ESU) to
insure an equal distribution between new residential and employment development. The
standard residential water meter in the City of Coppell is a 5/8 "x3 /4" meter. Therefore,
for uniformity, impact fee calculations were based on a 5/8 "x3 /4" meter = 1 ESU for
water and wastewater. As with the water system, other meter sizes were converted to
ESU's using the factors published by the Ttwm Rural Water Association ( Table 4). For
the wastewater system, irrigation meters and fire service meters were not included, since
these meters do not generate any wastewater demand. The total existing ESU's for the
wastewater system are summarized in Table 7.
Sanitary Sewer System Impact Fees
For the purpose of computing sanitary sewer impact fees, a service unit has been defined
as a single family residence equipped with a 5/8 "x3/4" meter and will generate 335
gallons of sewage per day on the average. Based on this definition, there will be
11,647.7 equivalent service units by the year 2004. Additional 10 -year equivalent
service units, by land use category, are presented below:
