CITY OF WYLIE
THOROUGHFARE CAPITAL IMPROVEMENT PLAN
ROADWAY IMPACT FEES
The first step in the development impact fee process is the development of a 10-year Capital
Improvement Plan (CIP). This capital improvement plan includes projects intended for
construction by the City of Wylie in the next 10 years to serve existing and future development.
Existing Facilities
The City of Wylie arterial and major collector street system is partially developed at this time.
Several roadways in developed areas are partially built to current thoroughfare plan standards.
Many existing streets are two-lane asphalt roadways with open surface drainage.
The existing Principal/Major Thoroughfares within the City include State Highway 78 (SH 78),
FM 544, FM 1378 (Country Club Road), McMillen Road/Park Boulevard, and Parker Road.
Several roadways, including SH 78 and FM 544, are under the operation and maintenance
jurisdiction of the Texas Department of Transportation (TxDOT).
Proposed Facilities
The City of Wylie adopted an updated thoroughfare plan in 2018 that is the basis for development
of the future street system. The thoroughfare system is a conventional network conforming to a
hierarchical, functional classification system developed to support the forecast traffic demands of
future land use.
The highest classification of roadway is the Principal Thoroughfare type facility, followed by the
Major Thoroughfare and Secondary Thoroughfare facilities. These roadways are generally multiple
lanes — 4 lanes for Secondary or 6 lanes for Principal and Major Thoroughfares. These roadways
also generally include medians that serve the function of controlling access, separating opposing
traffic movements and providing an area for the storage of left turning vehicles. The lower
classifications are the Collector and Downtown Collector facilities that are developed to serve the
adjoining development. The character of the developments served should determine the sizes and
alignments of collector roadways.
City of Wylie—2019 Roadway Impact Fee Update Page 1
Capital Improvement Plan for Roadway Impact Fees
The thoroughfare facilities determined for inclusion in the Capital Improvement Plan of this study
are tabulated in Table lA and graphically illustrated in Figure 1. Each listed project includes a
description of the planned improvements, the approximate project length, and an engineer's opinion
of probable cost to the City. In addition, under existing State Statute, a municipalities' cost
associated with TxDOT facilities can be financed with impact fees. All roadways included in the
2019 CIP are identified in the City of Wylie Thoroughfare Plan. Table lB shows recoupment costs
for projects completed as part of the previous CIPs with debt not retired. These recoupment
projects are also illustrated in Figure 1.
The engineer's opinions of probable construction cost were prepared without the benefit of a
detailed preliminary engineering study for each project. The costs are based on data provided by
the City of Wylie and on recent roadway project construction bids. Financing costs for the projects
in the thoroughfare CIP were also included in the total estimated cost and the interest rate of 5%
was provided by the City of Wylie.

IMPACT FEE CALCULATION
I. INTRODUCTION
The next step of the Development Impact Fee process is the determination of the maximum
fee per service unit that can be charged by the City for new developments. The fee is
calculated by dividing the costs of the capital improvements identified as necessary to serve
growth forecast to occur during the 10 -year planning period by the number of service units of
growth forecast to occur. The specific steps, as described in following paragraphs of this
section include:
1. Determination of a standard service unit;
2. Identification of service areas for the City;
3. Identification of that portion of the total capital improvements necessary to serve the
projected growth over the next 10 -year period;
4. Analysis of the total capacity, level of current usage, and commitment for usage of
capacity of existing improvements;
5. Determination of the "standard service unit" and equivalency tables establishing the ratio
of a service unit to the types of land use forecast for growth.
II. SERVICE UNIT
To determine the impact fee rate applied to thoroughfare facilities the standard service unit
selected was "PM Peak Hour Vehicle -Miles." This service unit can be obtained by
multiplying the number of trips generated by a specific land use type during the PM peak
hour (vehicles) by the average trip length (miles) for that land use. The PM peak hour was
chosen because it is usually considered the critical time for roadway analyses. The trip
generation data were directly obtained or derived for each defined land use type from "Trip
Generation Manual, 10" Edition" of the Institute of Transportation Engineers, which is the
standard data reference to determine vehicle trip generation characteristics of particular land
use types and densities. Trip length information for each land use specified was based on data
developed by the Federal Highway Administration (FHWA) in the 2017 National Household
Travel Survey. The trip length was set at a maximum of three (3) miles for any land use, as
this trip length was assumed to be the maximum average distance a trip would travel on
roadways within each service area in the City of Wylie. Table 2 shows the typical service
units for each land use type.

SERVICE AREAS
The State Statute governing the imposition of development impact fees require that collection
and expenditure of fees imposed for street facilities "...is limited to an area within the
corporate boundaries of'the political subdivision and shall not exceed six miles." To comply
with this State Law, two service areas (West and East) were established for the City of Wylie
to ensure that funds are spent within six miles of where they are collected. The service areas
include most of the developable land within the city limits of Wylie. Within Wylie, the
growth and intensities of growth for the ultimate development of the City and that portion of
the service area expected to occur during the 10 -year period, 2019-2029, is forecast. The two
service areas were shown in Figure 1.
III. ASSUMPTIONS AND EVALUATION CRITERIA
Determination of the eligible costs of capital improvements to serve the forecast growth over
the 10 -year period from 2019 to 2029 was based on data provided by the City of Wylie. The
basic criteria and assumptions made for this study include the following:
1. Costs of existing facilities constructed to serve new development have been included, and
City of Wylie staff identified projects of this type.
2. Bond interest costs are included.
3. Street facility improvements, although necessary for additional capacity by new growth,
will logically serve all existing and future growth by improved safety and drainage
characteristics. Therefore, the 10 -year eligible costs have been proportioned as the ratio
of the 10 -year growth to the total number of service units determined for the build -out.
Table 3 shows the portion of ultimate build -out service units that will be attributable to
growth within the next 10 years and is used to pro -rate the identified costs in the service area.
In order to maintain the equity of impact fee assessment, the cost for streets included in the
10 -year Capital Improvement Plan will include the total cost of the street facilities, not
reduced by any expected participation. Rather, construction by a developer of an arterial
facility within or off-site should be treated as a credit to the impact fee assessment.

ELIGIBLE COSTS
Table 4 presents a summary of the roadway capital improvement costs for the two service
areas. The 10 -year portion of the total costs was calculated using the data from Table 3.
Costs of each of the individual street projects were accumulated, or apportioned, for the
service area in which they were located. Boundaries of the service areas were located to be
coincident with natural barriers, the center of existing or proposed street facilities included in
the capital improvements plan or along city limit lines. Costs of these projects included only
those costs that will be paid for by the City of Wylie.
IV. DETERMINATION OF STANDARD SERVICE UNIT AND EQUIVALENCY
The determination of growth of service units and resulting impact fee rates were then made.
Table 5 presents the derivation of service unit equivalents for each of the six defined land use
types. The service unit equivalents are referenced to and based on the residential land use.
Table 6 presents a summary of the calculations and resulting eligible costs per service unit.
Under current State law, municipalities are required to administer a detailed financial analysis
to support the use of an impact fee higher than 50 percent of the eligible costs. As an
alternative to performing the financial analysis, the impact fee can be set at or below 50
percent of the total eligible costs. The total eligible costs per service unit are shown in
Table 6. The City will use either a detailed financial analysis to adjust for tax credits or will
use 50 percent of these eligible costs.
V. IMPACT FEE CALCULATION METHODOLOGY
The methodology for calculating the maximum allowable impact fee for roadway facilities
can be summarized in the following three steps. First, determine the cost of the roadway
facilities (existing roadways eligible for recuperation of construction cost and proposed
roadways) that can be attributed to new growth over the 10 -year period. This calculation for
Service Areas W and E are summarized on pages 14 and 15.

Calculation for Service Area W
Cost of Roadway Facilities (Tables IA and 1B - Service Area W) = $127,120,274.00
Proportion of Capacity Attributable to New Growth (Table 3 - Service Area W) = 0.037
Cost of Roadway Facilities Attributable to Growth (2019-2029 - Service Area W):
$127,120,274.00 x 0.037 = $4,703,450.14
The second step is to determine the maximum calculated impact fee. The maximum calculated
impact fee is the ratio of the total cost for roadway facilities attributable to growth in the next ten
years (2019-2029) divided by the total growth in equivalent service units (ESU). The maximum
calculated impact fee for Service Area W is:
Maximum Roadway Impact Fee = Eligible Thoroughfare Cost Attributed to Growth (Table 4)
Total Growth in Equivalent Service Units (Table 3)
_ $4,703,450.14
2,608 ESU
= $1,803.47 / ESU = $1,803 / ESU (Rounded Service Area W)
This amount represents the maximum calculated impact fee for roadway facilities. For the final
step, the current impact fee legislation requires the City to produce a financial analysis to support
a fee greater than 50 percent of the eligible costs or to reduce the maximum calculated impact fee
by 50 percent. If the City chooses to use a maximum allowable impact fee of 50 percent of the
maximum calculated fee the amount would be $1,803 x 50% = $901.50.
alculation for Service Area E
Cost of Roadway Facilities (Tables I and 1B - Service Area E) = $225,140,632.17
Proportion of Capacity Attributable to New Growth (Table 3 - Service Area E) = 0.120
Cost of Roadway Facilities Attributable to Growth (2019-2029 - Service Area E):
$225,140,632.17 x 0.120 = $27,016,875.86
City of Wylie — 2019 Roadway Impact Fee Update Page 14
The second step is to determine the maximum calculated impact fee. The maximum calculated
impact fee is the ratio of the total cost for roadway facilities attributable to growth in the next ten
years (2019-2029) divided by the total growth in equivalent service units (ESU). The maximum
calculated impact fee for Service Area E is:
Maximum Roadway Impact Fee = Eligible Thoroughfare Cost Attributed to Growth (Table 4)
Total Growth in Equivalent Service Units (Table 3)
_ $27,016,875.86
5,831 ESU
_ $4,633.32 / ESU = $4,633 / ESU (Rounded Service Area E)
This amount represents the maximum calculated impact fee for roadway facilities. For the final
step, the current impact fee legislation requires the City to produce a financial analysis to support
a fee greater than 50 percent of the eligible costs or to reduce the maximum calculated impact fee
by 50 percent. If the City chooses to use a maximum allowable impact fee of 50 percent of the
maximum calculated fee the amount would be 54.633 x 50% = S2.316.50.
Impact Fee Calculation Example
The land use equivalency table is provided in Table 7. This table identifies the total service units
generated by specific uses within each land use category. To obtain the impact fee to be charged
for a particular land use, the impact fee per service unit adopted by the City and the service units
per development unit generated for that particular land use from Table 7 are used. Examples for
calculating the impact fee for both a single-family dwelling unit and a 50,000 ft2 shopping center
(commercial / retail facility) assuming impact fees of $901.50 per service unit (Service Area W)
and $2,316.50 per service unit (Service Area E) are shown on page 17.

IMPACT FEE UPDATE
2019 - 2029
ummmmm
CITY OF WYLIE
I NEW
Birkhoff, Hendricks & Carter, L.L.P.
On April 24, 2001, the City of Wylie adopted Ordinance No. 2001-19 "Establishing Water and
Wastewater Impact Fees" in accordance with Chapter 395 of the Local Government Code. The
ordinance and associated impact fees were established and based on the Service Area Land Use
Assumptions and Capital Improvements Plan prepared by Hunter Associates of Texas, Ltd.,
dated March 2001. The City updated their water and wastewater impact fees by Ordinance
2012-18 in response to the adoption of a new Comprehensive Land Use Plan in .May 2012 and
an expansion of the City's corporate boundaries and environmental jurisdiction. The maximum
calculation fee and current imposed fees are summarized below:
Chapter 395 requires that an update of the land use assumptions, capital improvements plan,
and impact fees be performed every five years, unless it is determined by the political
subdivision after a review that such an update is not necessary.
In accordance with the requirements of Chapter 395.052 of the Local Government Code, this
report reviews the City of Wylie's Land Use Assumptions and updates the Capital
Improvement Plan.
Chapter 395, of the Local Government Code is an act that provides guidelines for financing
capital improvements required by new development in municipalities, counties, and certain
other local governments. The basis for determination of an impact fee requires the
preparation and adoption of a land use plan and growth assumption, and the preparation of a
10 -year capital improvement plan. A master plan of the water and wastewater systems is

necessary to prepare a 10 -year capital improvement plan. From these two phases, a maximum
impact fee is calculated.
The Act allows the maximum impact fee to be charged if revenues from future ad valorem
taxes and water and sewer bills are included as a credit in the analysis. If not, the Act allows
the maximum fee to be set at 50% of the calculated maximum fee. The following items were
included in the impact fee calculation:
A. The portion of the cost of the new infrastructure that is to be paid by the City, including
engineering, property acquisition and construction cost.
B. Existing excess capacity in lines and facilities that will serve future growth and which
were paid for in whole or part by the City.
C. Engineering and quality control fees for construction projects.
D. Interest and other finance charges on bonds issued by the City to cover its portion of cost.
The engineering analysis portion of the Water and Wastewater Impact Fee review determines
utilized capacity cost of the major water distribution and wastewater collection facilities
between the year 2019 and the year 2029. Facilities in this analysis include, water pump
stations, elevated and ground water storage tanks, water transmission lines, wastewater
treatment plants, wastewater lift stations and wastewater collection lines. The North Texas
Municipal Water District (NTMWD) owned water treatment and distribution components
were excluded from this analysis. The study period is a ten-year period with 2019 as the base
year. The impact fee calculation for the water and wastewater systems is based on land uses
provided by the City of Wylie. Concurrently with this Impact Fee Update, the City's Water
Distribution Master Plan has been updated. The Master Plans are available for review from
the City of Wylie. The equivalency factors utilized in this analysis conform to the latest
American Water Works Association Standards (C700 - C703).

III. LAND USE ASSUMPTIONS (Provided By: The City Of Wylie)
A. Purpose
Chapter 395 of the Texas Local Government Code prescribes the process by which cities
in Texas must formulate development impact fees. The initial step in this process is the
establishment of "Land use assumptions" for the City upon which the impact fee program
is based. An executive decision has been made to use the 2005 Future Land Use Plan
instead of the 2012 Future Land Use Plan due to the land use categories used in the 2012
Future Land Use Plan being too broad for a hydraulic analysis. These land use
assumptions, which are derived from the 2005 Future Land Use Map and from the 2018
Population Projections provided by City Staff, will become the basis for the preparation
of impact fee capital improvement plans for water and wastewater facilities.
To assist the City of Wylie in determining the need for, and the timing of, capital
improvements to serve future development, a reasonable estimation of future growth is
required. The growth and development projections were formulated by the City of Wylie
based upon assumptions pertaining to the type, location, quantity and timing of various
future land uses within the community, and to establish and document the methodology
used for preparing the growth and land use assumptions.
B. Elements of The Land Use Assumption Report
This report contains the following components:
1) Methodology -- Explanation of the general methodology used to prepare the land
use assumptions.
2) Service Zone Map — The impact fee service area for water and wastewater
facilities is shown on Figure 1.
3) Base Data — Information on population and land use for Wylie for each capital
facility/impact fee service area.
4) Ten -Year Growth Assumptions — Population and land use growth assumptions
for ten years for each capital facility/impact fee service area.
5) Ultimate Population Projections — Projections that reflect a completely developed
condition, based upon the City's ultimate "build -out" scenario.
6) Summary — Brief synopsis of the land use assumptions report.

C. Methodolo2
Based upon the growth assumptions and the capital improvements that will be needed to
support future growth, it is possible to develop an impact fee structure which fairly
allocates capital improvement costs to growth areas in relationship to their impact upon
the entire infrastructure system. The database and projections in this report have been
formulated using reasonable and generally accepted planning principles and
methodologies.
These land use assumptions and future growth projections take into consideration several
factors influencing development patterns, including the following:
1) The character, type, density and quantity of existing development
2) Existing land use patterns
3) Anticipated future land uses (as shown in the City's 2005 Future Land Use Plan)
4) Availability of land for future expansion, and the City's physical holding capacity
5) Current growth trends in the City and region
6) Location and configuration of undeveloped (vacant) land
7) Known or anticipated development projects
8) Potential sanitary sewer availability (e.g., topographical constraints)
9) Growth policies adopted in the Future Land Use Plan
A summary of the general methodology used for the preparation of this report follows:
1) Establish impact fee water and wastewater service areas (Part III D — Service Area
Map).
2) Collect/determine benchmark (i.e., base year) data on population and land use as of
January 2018 (Part III E — Base Year Data).
3) Project population and land use growth for ten years by impact fee service areas
(Part III F — Ten -Year Growth Assumptions).
4) Project the ultimate population for a fully developed City, assuming full
development of service area(s) (Part III G — Ultimate Population Projections).
A more detailed methodology for each is contained within the referenced sections.

D. Service Area Maps
Figure 1 on the following page shows the proposed service area for water and wastewater
facilities. The service area boundary for wastewater includes all land area within the
existing City limits, all land within the Wylie Water CCN, and those portions of shared
Water CCNs that Wylie will provide wastewater facilities as development occurs. The
service area boundary for water includes all land within the Wylie Water CCN, and those
portions of shared CCNs that Wylie will serve as development occurs. However,
portions of the existing and proposed development within the City limits obtain water
from alternative suppliers, namely the Wylie Northeast Water Supply Corporation
District and the Eastfork Special Utility District. This background information provides
insight to the discrepancy between the overall City population and the population within
the water service area (discussed later in the report). A recommended priority listing of
projects for water and wastewater facilities will be outlined in the City's Capital
Improvements Program (CIP). The actual ten-year CIP upon which the impact fee
program must be based has been prepared, per the requirements of Chapter 395.

E. Base Year Data
This section documents historical growth trends and base data for the City. This
"benchmark" information provides a starting basis of data, as established in the City's
Future Land Use Plan and updated in April 2005, and the City's Comprehensive Land
Use Plan, adopted in 2012 for the ten-year growth assumptions.
One method of predicting future growth is looking at past growth. The historical growth
rates for Wylie are shown in Table 1 below.

Over the 40 -year period of 1970 to 2010, the City of Wylie experienced a significant
amount of growth. The City is continuing to experience an increase in population,
housing, and commercial development activity, although the rapid growth experienced
through the early 2000's began tapering down in 2006-2007 due to a variety of economic
factors. As of 2018,.the City of Wylie is projected to have a total of around 600
residential lots to be constructed. The build -out of these lots will increase the existing
housing stock as follows: 17,128 existing units (2018) + 600 future units (2019) = 17,728
units or a 3.5% increase. Accordingly, it is anticipated that the City has the lot inventory
to maintain the increases in population and housing growth experienced over the last few
years.
It is also anticipated that the City will continue to receive petitions for the zoning and
platting of new subdivisions.

Another comparison and useful base data source for population growth is the past trends
in residential construction. Table 2 shows the growth trend in residential construction in
the City from 2013 to 2018. At the end of 2013 there were approximately 15,024
residential units; this is the base number for percentage of growth.

(1) City of Wylie 2018 Population Projections
The growth in housing shown in Table 2 illustrates the recent trend in residential activity
for the City of Wylie. The trend shown here reflects that observed for the recent trend in
population growth. The City has seen moderate gains in residential growth over the past
few years. As mentioned earlier, the City's available lot inventory is increasing.
For the purposes of documenting changes in population, land use, density and intensity,
the data format to be used as a basis to formulate the land use assumptions will be
principally population and land use estimates. These estimates and the land use
inventory, from the City's 2005 Future Land Use Map, were used to establish a beginning
baseline and updated to June 2018 for the population projections provided by the City.
1) Population and Land Use
Existing land uses were documented throughout each of the service areas in
development of the Land Use Plan. Residential and non-residential building
activity for each of the service areas was then analyzed to establish base population
for 2018.
j:Ac1erica1\wyheA2018-118 w&ww-thoroughfare-impact feeAcip & impact feeArepmrts\03-report.doc -12-
Birkhoff, Hendricks & Carter, L.L.P.
The estimated population in 2018 for both service areas is:
Water Wastewater
■ Population ........................... 43,147 ......................... 52,003
■ Dwelling Units .................... 14,479 ......................... 17,451
■ Households .......................... 13,842 ......................... 16,683
These residential calculations are based on the following assumptions:
■ Occupancy Rate .................... 95.6 percent (2010 U.S. Census for Wylie); and
■ Average Household Size ....... 2.98 persons/household (2010 U.S. Census).
2) Land Use
Prior to an evaluation and projection of future land use patterns, an understanding
of existing conditions is essential. Documentation of existing land use patterns
within the City and its ETJ was included as part of the Land Use Plan prepared by
others. This data was updated based on information provided by the City to reflect
residential and non-resident development activity that occurred through 2018. This
documentation provides an overview of the general present physical composition
and condition of the City.
Table 3 shows a summary of estimated existing land uses for the land area within
the water and sanitary sewer service zones.

F. Ten -Year Growth Assumptions
Growth is characterized in two forms: population (residential land use) and non-
residential land use. Several assumptions were necessary in order to arrive at reasonable
growth rates for population and employment in the City of Wylie. The following
assumptions were made as a basis from which 10 -year projections are initiated:
1) Future land uses will occur as shown on the Future Land Use Plan.
2) The City will be able to finance the necessary improvements to the water and
wastewater systems to accommodate expected growth.
3) School facilities will accommodate expected increases in school-age population.
4) Densities will be as projected, based upon anticipated zoning districts.
5) Known or anticipated development projects will occur as presently planned.
The 10 -year projections, or land use assumptions, are based upon the establishment of a
reasonable growth rate based upon past trends and/or other considerations. Considering
the increasing trends in population and housing growth (Table 2) and the City's proximity
to the Dallas/Fort Worth metropolitan area and combining these factors with anticipated
development projects provides a reasonable indication of growth potential. Based upon
these assumptions, the annual average number of residential dwelling units constructed
j:Aclerica➢wyheA2018-118 w&ww-thoroughfare-impact feeAcip & impact feeArepmrts\03-report.doc - 15 -
Birkhoff, Hendricks & Carter, L.L.P.
per year over the next 10 -year period is projected to be approximately 234. A household
size of 2.98 persons per household with an occupancy rate of 95.6 percent was used to
calculate the future population based on the projected residential activity. The 2018
population of 52,003 (source: City of Wylie) is projected to increase to approximately
58,667 by the year 2028, representing a compounded annual growth rate of 1.2%. This
rate would generate an average population increase of about 667 persons per year. The
following shows the formula for calculating the ten-year growth assumptions:
Residential:
234 dwelling units x 0.956 occupancy rate = 224 occupied dwelling units/year
224 occupied dwelling units/year x 2.98 household size = 667 persons/year (+/-)
667 persons/year x 10 years = 6,670 persons net 10 -year residential growth
"Note: It should be noted that the 10 year population and housing projection assumes growth potential
within the existing municipal boundaries and the existing extraterritorial jurisdiction (ETJ).
These projections do not assume residential growth beyond the existing ETJ. "
This rate of growth (1.2% compound annual growth rate) is a conservative reasonable rate
for Wylie to be expected to grow at over the next 10 years. The growth rate projected for
Wylie is less than the compounded annual growth rate over the last 8 years (2.88%) and is
consistent with other comparable cities within the region.
Table 5 shows the average annual compounded growth rates for other cities in the area
and for Collin County from 2010 to 2018:.

Table 5 illustrates that the regional growth pattern is continuing to move outward from
Dallas toward the City of Wylie. Those cities that experienced the greatest amount of
growth from the 1980s to the 1990s have achieved significant levels of build -out and
those cities further north have begun to experience significant population and housing
increases. Those cities north and west of Wylie are currently experiencing growth rates
similar to those projected for Wylie through 2028.
The projected annual growth rate for the City of Wylie and the resulting population
projection of 58,667 persons (48,694 persons within Wylie's Water CCN) for the 10 -year
planning horizon is considered reasonable for planning purposes. As mentioned, this
growth is projected throughout the City's water and wastewater service area, with a
substantial amount of the growth being beyond the current municipal boundaries during
the next ten years. The previously described growth rate represents growth throughout
the water and wastewater service zones.
It is anticipated that most of this projected growth will ultimately be incorporated into the
City service area limits for several reasons:
1) More stringent environmental laws pertaining to septic waste systems.
2) Increasing insurance rates outside corporate City limits.
3) The City's progressive philosophy regarding water and sewer line extensions.
4) Proposed upgrading of construction standards in the City's ETJ.
Changes in population affect the use of land. In the case of Wylie, increased population
is due to the conversion of vacant or agricultural land into residential and other land uses.
Non-residential development will increase to provide the goods and services that the
increased population will demand. The estimation of the additional acres to be developed
for the next 10 years will aid in the determination of demand for additional water and
wastewater facilities.

The future acres per 100 persons reflect those ratios that have been observed for Texas
cities with healthy local economies. It should be noted that these ratios also closely
reflect the existing land use mix for Wylie's water and wastewater service areas. The
ratios are used to calculate the amount of non-residential development that the local
population may support.
G. Ultimate Population Proiection
An ultimate, or holding capacity, land use and population projection was also established
in the City of Wylie's Future Land Use Plan. First, known densities of development were
considered. Then, based upon the remaining developable vacant land in Wylie and its
ETJ, densities of anticipated development projects were applied. The ultimate population
of the City of Wylie is a function of anticipated residential land use area (acres), housing
density (dwelling units per acre), and population density (persons per dwelling unit).
Based upon the land uses identified on the Future Land Use Plan, the total ultimate land
use areas of residential development were calculated using the density standards adopted
as part of the Future Land Use Plan. The ultimate holding capacity for the planning area,
assuming that each residential area is built out to its maximum capacity, generates a
maximum population of approximately 50,589 persons for the water service area and
60,950 persons for the sewer service area, excluding the unincorporated Lake areas.

H. Summary
The data used to compile these land use assumptions were from three sources, anticipated
development for the City of Wylie, residential building data and other data from the City,
and information from the Future Land Use Plan. The ten-year growth projections were
calculated based upon reasonable growth rates and trends for Wylie and the surrounding
area. Ultimate projections were based upon the holding capacity of vacant land using
land use types and applying densities as established by development policies, the Future
Land Use Plan, and known proposed development plans.
The land use assumptions may be summarized as follows:
1) The Wylie wastewater planning area contains approximately 19.75 square miles.
2) The 2018 estimated population in the existing water service area is 43,1.47. The 2018
estimated population in the existing wastewater service area is 52,003.
3) The ten-year growth projections were calculated using a compounded average annual
growth rate of approximately 1.2%.
4) The ten-year population projection for Wylie is approximately 48,694 persons inside
the water service area and 58,667 in the sanitary sewer service area. As noted, the
population within the water service area excludes those residents obtaining water
from providers other than the City of Wylie and the population within the sanitary
sewer service area excludes a small percentage not connected to the wastewater
system.
5) The ultimate (build -out) population within the water service area is approximately
50,589 persons and 60,950 persons in the wastewater service area, according to the
2018 population projections.

Chapter 395 of the Local Government Code requires that impact fees be based on a defined
service unit. A "service unit" is a standardized measure of consumption, use generation, or
discharge attributable to an individual unit of development calculated in accordance with
generally accepted engineering or planning standards. This update defines a water and
wastewater service unit to be a 3/4 -inch water meter and has referred to this service unit as a
Single Family Living Unit Equivalent (SFLUE). The SFLUE is based on the continuous duty
capacity of a 3/4 -inch water meter. This is the typical meter used for a single-family detached
dwelling, and therefore is considered to be equivalent to one "living unit". Many single-family
dwellings were constructed with 5/8 -inch meters in the City; therefore, 5/8 -inch meters are also
considered one "living unit". Other meter sizes can be compared to the 3/4 -inch meter through
a ratio of water flows as published by the American Water Works Association as shown in
Table 7 below. This same ratio is then used to determine the proportional water and
wastewater impact fee amount for each water meter size.

The City of Wylie provided the existing water meter count by size category as of June 2018. In
total, there are 13,048 water meters serving the existing population of 43,147 residents and
businesses. Table 8 shows the number of existing meters, the living unit equivalent factor and
the total number of living unit equivalents for water accounts.
The City reports there are 16,341 accounts in 2019, this represents an approximate annual
increase of 2.91% and is similar to the growth rate for the water system. Table 9 illustrates the
existing accounts and SFLUE's based on the same percentage of growth as shown in the water
system.
Using the growth rate provided by the 2018 Population Projections prepared by the City, a
straight-line extrapolation of water meters and wastewater accounts were calculated for the year
2028. Living unit equivalents were then applied to the water meters and wastewater accounts
for 2018 and 2028 resulting in a total number of living units. The difference in the total
number of 2018 and 2028 living units results in the new living unit equivalents during the
impact fee period. The calculation of living unit equivalents is summarized in Table 8 and
Table 9.

Birkhoff, Hendricks & Carter, L.L.P.
Birkhoff, Hendricks & Carter, L.L.P. Professional Engineers prepared computer models for the
years 2018 and 2028. The models were developed from the 2018.Population Projections
provided by the City of Wylie. The land areas follow closely to the construction of major
facilities in the system as outlined in Figure 2. These facilities include major distribution lines,
pump stations, ground storage reservoirs and elevated storage tanks. All computer models were
run for the Maximum Hourly Demand and the Minimum Hourly Demand to insure proper
sizing of the facilities to meet peak demand periods.
A. Existing Pump Stations, Ground Storage Reservoirs & Elevated Storage Tanks

The pump stations and ground storage facilities were analyzed with the maximum daily demand,
while elevated storage act dynamically and are therefore analyzed utilizing the difference between the
Maximum. Hourly Demand and the Maximum Daily Demand.
B. Distribution Lines
The distribution lines consist of all lines within the service area boundary supplying water
to customers in the City of Wylie. Lines vary in size from 5/8 -inch and 3/4 -inch services to
j:Aclerica➢wyheA2018-118 w&ww-thoroughfare-impact feeAcip & impact feeArepmrts\03-report.doc -23-
Birkhoff, Hendricks & Carter, L.L.P.
24 -inch transmission lines. Only those water lines 12 -inches and larger in diameter were
considered in the Impact Fee calculations. The cost of water lines includes the
approximate construction cost, appurtenances (water valves, fire hydrants, taps and the
like), utility relocations, purchase of easements, and engineering costs in 2018. Financing
cost over a 20 -year term with an assumed bond rate of 5% is included for each project.
Unit cost for proposed capital improvement water lines 12 -inches and larger in diameter
were classified as City initiated water lines including the full cost of the facility. Developer
initiated water line projects, 12 -inches or less in diameter, are not included in this Impact
Fee analysis, as the cost for these size lines are the responsibility of the developer.
C. Water Supply
The City of Wylie currently receives all of its water supply from the North Texas
Municipal Water District (NTMWD). Wylie's allocation of the capital cost of services as a
customer of the NTMWD was specifically excluded from the impact fee analysis.
If included, Wylie's share of the NTMWD capital cost could include the original
construction cost, expansion cost, financing cost, engineering cost and real estate cost of
the following components:
1) Water Rights Cost in Lake Lavon and Other :Reservoirs
2) Raw Water Intake Structures
3) Raw Water Pump Stations
4) Water Treatment Plant and Expansions
5) High Service Pump Stations
6) Transmission Lines
7) NTMWD Owned Ground Storage Facilities
8) Metering Facilities

Birkhoff, Hendricks & Carter, L.L.P.
D. Water Distribution System Capital Improvement Projects
In order to meet the demands of the anticipated growth over the next 10 -years, as provided
in the 2018 Population Projections, certain water distribution system improvements are
required. Figure 2 shows the recommended system improvements and Table 11 itemizes
each project and the project cost. These recommended improvements assist to form the
basis for the Water System Impact Fee Calculation.
Actual capital cost, including construction, engineering and easements of the various
elements of the existing water distribution system was utilized where the information was
known. The existing cost of facilities was determined from records provided by the City of
Wylie. Where actual costs are not known, an average cost in 2018 dollars has been
calculated. The average unit cost is from a limited survey of projects, which bid recently,
plus an estimated cost for engineering and easements. There are many variable factors that
can have a significant impact on the actual construction cost of a project such as local
conditions, material cost increases and fuel cost increases to name a few.
The capital improvement plan provides for system improvements within the defined service
area. Some of'the system improvements may be physically located beyond the boundaries
of the services area; however, they are necessary to provide adequate system service and
capacity.

Utilized Capacity
Utilized capacity for the water distribution system was calculated based on the water line
size required for each model year (2018, 2028 and build out). Master planning of the water
distribution system is based on the maximum daily demand, maximum hourly demand, and
the minimum hourly demand. Pump station capacity is generally based on the maximum
daily system demand while transmission and distribution facilities are sized based on either
the maximum hourly demand or the minimum hourly demand, whichever demand is
greater for a particular water line. Often, the capacity of a water line is determined by the
flows generated by the minimum hourly demand. The minimum hourly flows are usually
higher in those lines that are used to refill elevated storage. For each line segment in the
water distribution model, the build -out flow rate in the line was compared to the flow rate
in the same line segment for the 2018 and the 2028 models.
The percentage of utilized capacity was calculated for each year based on the build -out
capacity. The utilized capacity during the Impact Fee period is the difference between the
year 2028 capacity and the year 2018 capacity. Table 12 below summarizes the total 20 -
year project cost and utilized cost over the impact fee period of 2018 - 2028 for each
element of the Water Distribution System. The total 20 -year cost includes financing cost
over a 20 -year term with an assumed bond rate of 5%. The utilized capacity for each water
distribution facility, both existing and proposed, is presented in detail in Impact Fee
Capacity Calculation Tables 13, 14, and 15.

VII. WASTEWATER COLLECTION SYSTEM
A. General
At this time, most of the wastewater generated in the City of Wylie (concentrating in
areas adjacent to the present city center) flows by gravity and a combination of lift
stations and force mains to the Muddy Creek Regional Wastewater Treatment Plant
(operated by the NTMWD) southwest of the City center. The Wylie Wastewater
Treatment Plant located near the center of the City was decommissioned. A small
amount of current wastewater flow is handled through local residential septic systems.
The average daily flow capacity of the new Muddy Creek Regional Wastewater
Treatment Plant is 10.0 MGD and the peak flow capacity is 30.0 MGD.
This impact fee study considers no significant development in the Lake Ray Hubbard
Collection Basins prior to 2029. Therefore, infrastructure improvements are not planned
or included in the impact fee calculation.
Muddy Creek, Cottonwood Creek and Rush Creek Basins are anticipated growth areas.
1) Muddy Creek: Muddy Creek includes the bulk of the existing development and
produces the predominant volume of wastewater flow. The Muddy Creek Basin will
add approximately 3,895 to the population by 2029.
2) Cottonwood Creek: Generally south of the City center is an expected growth area
where approximately 919 will be added to the population by 2029.
3) Rush Creek: Generally east of the City center is an expected growth area where
approximately 1,234 will be added to the population by 2029.
B. Collection Lines
The wastewater collection system analysis is a static analysis covering all of the drainage
basins within the study area. The wastewater project cost includes necessary
appurtenances, purchase of easements, utility relocation, pavement removal and
replacement, and engineering costs. For existing Impact Fee projects, actual costs were
utilized where known. Future project cost estimates were based on budget information
provided by the NTMWD and include engineering, construction and inspection costs
when provided.
The natural ground in the area to be served by the Wylie Wastewater Collection System
varies in elevation from approximately 460 feet above mean sea level near the Muddy
j:Ac1erica1\wyheA2018-118 w&ww-thoroughfare-impact feeAcip & impact feeAreports\03-report.doc -34-
Birkhoff, Hendricks & Carter, L.L.P.
Creek Regional. Wastewater Treatment Plant to 620 feet above mean sea level near the
northwest City Limit. There is a natural divide running generally North to South near the
Wylie city center (following Ballard Avenue to the Pleasant Valley Road).
The land on the west side of this divide generally falls to the southwest and includes five
main basins. These basins are (from south to north) Lower Muddy Creek, Tributary 1 to
Muddy Creek, Tributary 2 to .Muddy Creek, Tributary 3 to Muddy Creek and Upper
Muddy Creek. The natural creeks, whose basins will collect wastewater through the
installed system of trunk lines, flow into the geographic area normally serviced by the
North Texas Municipal Water District.
The fall of the land on the east side of this divide is to the southeast and includes three
main basins. The basins are Cottonwood Creek (near the City center), Rush Creek (east
of the City center) and Tributary 1 to Rush Creek (east of the main channel). These
basins flow naturally into Lake Ray Hubbard. Flows in the City of Wylie service areas
are collected in Lift Stations at the downstream limit of the service area and lifted over to
the Muddy Creek basin.
C. Treatment
The Wylie Wastewater Treatment Plant is located just north of Alanis Drive and west of
Ballard Avenue. Currently, this plant no longer serves the City and was decommissioned.
The Muddy Creek Regional Wastewater Treatment Plant was constructed southwest of
the City center near Lake Ray Hubbard. An expansion of the Muddy Creek Regional
Wastewater Treatment Plant was completed several years ago and additional expansions
are anticipated over the next five years. The North Texas Municipal Water District
operates the Muddy Creek Regional Wastewater Treatment Plant.
D. Capital Improvement Program
The existing wastewater collection system is adequately designed to accommodate the
growth expected within the impact fee period; therefore, no improvements are required
based on the current projections. However, the current NTMWD wastewater treatment
plant is reaching capacity and the NTMWD plans to expand the capacity to accommodate
future growth. Due to this circumstance, there only new improvement shown in Table 15
is the City's percentage of the flow contribution times the cost of the expansion and the
portion predicted to be used for new development over the 10 -year CIP period.

Birkhoff, Hendricks & Carter, L.L.P.
E. Utilized Capacity
The Land Use Assumptions from the City of Wylie were utilized to calculate the utilized
capacity for the wastewater collection system based on land absorption from population
growth projections. The population and employment growth in each wastewater drainage
basin were determined based on the City's growth projections. These growth rates were
utilized to calculate 2018 and 2028 design flows. The following summarizes each design
flow component utilized to calculate the wastewater design flows.
1) Population Based Flow: For the purpose of this wastewater impact fee study an
average per capita flow of 110 gallons per day (gpcd) is a reasonable basis for the
design of the wastewater collection and treatment facilities. Peak flows associated
with this per capita rate have been estimated for various segments of the collection
system by using the following formula PF = ((5/(population/1000)^0.167). The
formula takes into account the estimated population, and, indirectly, the area of the
drainage basin to be served. This method gives a ratio of peak to average flows
varying from a maximum of 5.0 times the average flow for a population of 1,000 or
less to 2.32 times the average flow for a population of 93,700 (includes 18,000 for
the City of Murphy also served at the Muddy Creek Regional WWTP).
2) Non -Population Based Flow: Non-residential average flows are estimated based on
an average daily flow per acre for each non-residential land use category. The
following were used for average daily flow per acre for each category:
Business/Commercial Corridor: 1,600 gallons ... Commercial/Retail: 1,400 gallons
Neighborhood Services: 1,200 gallons ............... Public/Semi :Private: 1,000 gallons
Heavy Industrial: 2,400 gallons .......................... Light Industrial: 2,000 gallons
Parks/Open Space: 5 gallons .............................. Floodplains: 0.01 gallons
A 2.0 Peaking factor was used for each non-residential land use. The combination
of per capita and non-residential based flow is the basis for aggregate dry weather
flow in the basins.
3) Infiltration and Inflow: Groundwater can infiltrate into the sanitary sewer system
through faulty sewer pipe joints, tree roots, breaks in sewer pipes and manholes and
faulty service lines. Infiltration creates an average day flow related burden on
wastewater collection systems and treatment plants. Infiltration is fairly constant
and not necessarily based on temporary storm events. Normal plant capacity must
j:Ac1erica1\wyheA2018-118 w&ww-thoroughfare-impact feeAcip & impact feeArepmrts\03-report.doc -36-
Birkhoff, Hendricks & Carter, L.L.P.
be designed to handle infiltration related flows. The City is in the process of
completing a program to evaluate the actual flow rates of major system gravity
sewers and may embark on a program to rehabilitate lines that contribute significant
infiltration volumes when economically and environmentally feasible, and/or
desirable.
Inflow is generally related to storm events that increase groundwater and surface
water flow into the sanitary system. The additional flow is generally recognized to
enter through manholes, service lines, roof drains and storm drains. Inflow related
flows could cause surcharged sewers, overflows at manholes and peak flows to
surpass the capacity of the treatment plant. The wastewater collection system
planning calculations include a combined infiltration and inflow rate of 400 gallons
per acre per day (gpad) for the entire wastewater service area. This flow is not
peaked.
The percentage of utilized capacity was calculated for the design flow of each study year
based on the build -out capacity. The utilized capacity during the Impact Fee period is the
difference between the year 2018 capacity and the year 2028 capacity. Table No. 16
below summarizes the project cost and utilized cost over the impact fee period of 2018 -
2028 for each element of the wastewater system. The utilized capacity for each existing
wastewater facility and collection line is presented in detail in Impact Fee Capacity
Calculation Tables 17 and 18.

VIII. MAXIMUM IMPACT FEE CALCULATION — WATER & WASTEWATER SYSTEM
The maximum impact fees for the water and wastewater systems are calculated separately by
dividing the cost of the capital improvements or facility expansions necessitated and
attributable to new development in the service area within the ten-year period by the number
of living units anticipated to be added to City within the ten-year period as shown on Table 8
and Table 9. To simplify collection, we recommend the fee remain fixed throughout the next
5 -year period, unless changed by Council.
Water Impact Fee — Eligible Existing Utilized Cost + Eligible Proposed Utilized Cost
Number of New Living Unit Equivalent over the Next 10 Years
$3,050,078 + $14,607,851 = $17,657,929

Plunk, Commissioner Mike McCrossin, Commissioner Bryan Rogers, Commissioner Tommy Pulliam
and Commissioner Charla Riner. Commissioners Absent: Chair Ron Smith.
Staff present: Mr. Jasen Haskins, Planning Manager, Mr. Kevin Molina, Senior Planner, Ms. Mary
Bradley, Administrative Assistant, Mr. Chris Holsted, City Manager, Mr. Timothy Porter, Public Works
Director, Mr. Wes Lawson, Project Engineer, Mr. Sam Satterwhite, WEDC Director, and Mr. Jason
Griener, WEDC.
CONSENT AGENDA
A. Consider and act upon approval of the Minutes from August 20, 2019, Regular Meeting.
Commission Action
A motion was made by Commissioner Rogers, seconded by Commissioner Emerson, to approve the
minutes from August 20, 2019 meeting, as presented. A vote was taken and the motion carried 7-0.
REGULAR AGENDA
1. Consider and Act upon approval of written comments and direct a member of the committee to
file the written comments with the Planning Manager.
Staff Comments
Mr. Porter stated that the purpose of the meeting was to consider the Impact Fees, Land Use Assumptions
and Fee Study. Since the last meeting in August, the item went before Council and Council denied and
directed Staff for additional understanding and comments. Mr. Porter reviewed with the Commissioner
the revised report for Thoroughfare fees. He stated that upon discussion with Staff and the Consultants,
there are projects in the west zone that the City did not pay interest. Nothing else in the report changed
from August when the Commissioners last reviewed it. No calculations or changes in the east zone.
Minutes November 19, 2019
Impact Fee Advisory Committee
Page I
The Consultant told Staff prior to the meeting that the State Law states the Committee is to confirm the
accuracy of the study and offer an opinion of rates; but is not required to make a specific rate amount to
the City Council.
Mr. Joe Carter, Consultant, Birkhoff, Hendricks and Carter, LLP, 11910 Greenville Avenue, Suite 600,
Dallas, stated that the numbers are based upon the projected growth that the City and North Central Texas
Council of Governments determined as the growth rate over the next ten years, which may slow down in
the next ten years. Currently, the City has spent $142 million on road infrastructure within the last ten
years, not including state funds.
Commissioners discussed in length the purpose of reviewing the same report as August meeting. Mr.
Porter stated that the rates recommended to the City Council were denied. City Council wanted more
detail and comments from developers. Mr. Porter stated that because of the timeline, the consideration of
the report had to come back to the Commissioners. The recommended rate was $914 for the east and west
zone and due to the reduction of the interest the number has been reduced to $901.50.
Mr. Holsted stated that City Council wanted more time to get feedback from the business community and
others. State Law is very specific in the timeframe in which Council has to act on the fees. There was not
another meeting within the timeframe, so the process started over. The purpose of the study sets a
maximum rate that the City can impose. Ultimately it is Council's decision on the rate of the fees. Staff
believes that Council would like to have the Commissioners opinion on the rates.
Commissioners discussed the rates compared with surrounding cities. Mr. Porter encouraged the
Commissioners to compare the rates with the unit cost. However, it is difficult to know what the
surrounding cities put into their fees. City of Wylie does not include sales tax and other cities may.
Public Comments
Mr. Satterwhite, Director of WEDC, stated that determining the rates is complex, it is a fine line as we
want a balance. He further recommended that west and east zones remain equal.
Mr. John McClure, McClure Partners, P.O. Box 2935, recommended having the west and east zones
equal, and compare the fees with the neighboring cities.
Mr. Gary Taylor, Taylor and Son Builders, 109 N Jackson, recommended not raising the fees.
Mr. Mac McClure, McClure Partners, P.O. Box 2935, recommended having the fees comparative with the
neighboring cities.
Mr. Jon Lewis, representative for F.O. Birmingham Memorial Land Trust, 100 N Jefferson, Wylie, stated
that he is an investor on the east zone, and the increase in the fees would deterrent possible developers.
Mr. Porter, stated that he receives multiple calls from citizens regarding traffic and condition of the road.
Mr. Porter recommended the Commissioners to make motion for accuracy of the report; give an opinion
for water and waste water fees; give an opinion for the thoroughfare fees; and make a motion to direct a
person to file the written comments to City Council. He also encouraged the Commissioners to attend the
work session with City Council on December 10, 2019 after the regular Council Meeting, to discuss the
Land Use Rates.

Although the IFAC provided recommended impact fees following meetings on July 16 and August 6,
earlier this year, City Council did not reach agreement on the proposed fees and, due to requirements in
Texas law concerning the timeframe for reaching a decision, the process was returned to the IFAC for re-
evaluation and recommendation. The primary goals of the meeting, as laid out by Tim Porter, Public
1orks Director Ab i
1 . Analyze the report covering Water, Wastewater and Roadway Impact fees, as authored by Birkhoff,
Hendricks and Carter, LLP, consultants and to vote on a motion verifying the accuracy of said
report
2. Make a recommendation regarding Water and Wastewater impact fees
3. Make a recommendation regarding Roadway impact fees
The following actions were taken:
As to item #1 — The IFAC voted 7-0 verifying the truth and accuracy of the Impact Fee Report. It was
noted that there was a slight reduction in the West Roadway fee from 914.00 to $901.50 due to interest not
paid on a small number of projects. No other changes from the previous version of the report were noted.
As to Item #2 — The IFAC voted 7-0 in favor of the Water Impact Fee of $4,294.24 and the Wastewater
Impact Fee of $914.63. These are the same fees recommended previously and, through discussion of the
committee members, the rate of change from current fees was deemed reasonable.
As to Item #3 — The IFAC voted 6-1 in favor of leaving the East and West Roadway impact fees at current
levels ($400) due to several factors:
* The amount of increase proposed under the report would effectively eliminate development
in Wylie due to the comparative costs in neighboring cities
■ Proposed fees under the current report: West would go from $400 to $901.50, a
125% increase; East would go from $400 to $2,316.50, a 479% increase
* Previous recommendations of $914 for both East and West were not adopted by City
Council but no explanation was provided
* It was explained to the IFAC that the results of any action taken would be a
recommendation to the City Council only and that IFAC presence had been requested in a
City Council working session following the City Council meeting scheduled for Tuesday,
December 10. Polling of the IFAC members indicated a number of confirmations to attend
the working session, where an ultimate decision can be reached.

Discuss rehabilitation options for Stone Road (S. WA Allen Boulevard to Beaver Creek Road) and provide direction on
funding.
Collin County would like to begin rehabilitation construction on East Stone Road improvements when school lets out for
the summer in 2020. Using the County's contractor, the City of Wylie's estimated portion of this work is $615,466.71.
The City has discussed funding options with the County including an amortized 5 -year payback schedule with interest and
a split of funding over two (2) fiscal years that would not include interest. The County would prefer to have this in one
payment, if possible.
