REGULAR AGENDA
Work Session
Item 1
Work Session on Land Use Assumptions, Capital Improvements Plan, and modification
of impact fees.
Staff Presentation
Mr. Hoisted, City Engineer presented a slide show to the Commissioners
stating that the definition of Impact Fees from Texas Local Government Code
— Chapter 395, "means a charge or assessment imposed by a political
subdivision against new development in order to generate revenue for funding
or recouping the costs of capital improvements or facilities expansion
Minutes August 5,2014
Wylie Planning and Zoning Board

necessitated by and attributable to new development." It is basically a way to
offset costs for roadway expansion for new development coming into the city.
The Service Area cannot be greater than six miles, therefore the city is divided
into two (2) Areas, a Western Service Area and a Eastern Service Area. The
Standard Service Unit is number of trips generated by a specific land use type
during the PM peak hour (vehicles) multiplied by the average trip length
(miles) for that land use. The trip length is a maximum of three miles.
Currently the Western Service Area is $424.82, the proposed maximum
updated fee up to 50 percent is $846.57. The Eastern Service Area is $718.50,
the proposed maximum updated fee is $1,871.22.
The written comments by the Committee will be submitted to City Council on
September 23, 2014. The Committee may choose to have another work
session on August 19, and take an action consideration on September 2, 2014.
Board Discussion
Commissioners directed Staff to present a comparison from surrounding cities
including the new cities that Council recommended during the Compensation
Study. Staff cautioned the Commissioners when reviewing the fees to
consider the traffic, number of residential homes and tax base.
Commissioners expressed concern of the two service areas, and the cost
difference between the two. An option that was discussed was to have the two
service areas have the same costs. Another option Staff recommended was to
have zones for Downtown Historic District or South Ballard Overlay District,
having the fees waived or a fee waived in order to encourage redevelopment
to spur growth in those areas.
Mr. Sam Satterwhite, Director, WEDC, stated that the high rate of the impact
fees is deterrent to some new businesses coming into City of Wylie, and
significant issue.
Board Action
The Commissioners directed Staff to submit a comparison from the
surrounding cities.
The Commissioners desired to have another work session on August 19, 2014,
to discuss having a separate zone possibly in the Downtown Historic District.

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 (20' - 40' width) asphalt roadways with open surface drainage.
The existing major arterial roadways within the City include State Highway 78 (SH 78), FM 544,
FM 1378, Ballard Avenue, Brown Street, and Stone Road. Several of the arterial 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 a revised Comprehensive Plan in 2012 and an updated thoroughfare plan
in 2014 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. These roadways
are generally multiple lanes (4 or 6) with 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 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—2014 Roadway Impact Fee Update Page 10 of 26 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 1A 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
2014 CIP are identified in the City of Wylie Thoroughfare Plan. Recoupment costs for projects
completed as part of the previous CIP are shown in Table 1B and 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 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, 9th 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 for the Dallas-Fort Worth area by the North Central Texas Council of
Governments (NCTCOG). 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, 2014-2024, 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 2014 to 2024 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.

City of Wylie—2014 Roadway Impact Fee Update Page 22 of 26 Page 13
Calculation for Service Area W
Cost of Roadway Facilities (Tables lA and 1B - Service Area W) = $95,566,342.00
Proportion of Capacity Attributable to New Growth (Table 3 - Service Area W) = 0.066
Cost of Roadway Facilities Attributable to Growth (2014-2024 - Service Area W):
$95,566,342.00 x 0.066 = $6,307,378.57
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 (2014-2024) 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)
= $6,307,378.57
4,255 ESU
= $1,482.35 /ESU= $1,482 /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 $1,482 x 50% = $741.00.
Calculation for Service Area E
Cost of Roadway Facilities (Tables 1A and 1B - Service Area E) = $172,380,939.75
Proportion of Capacity Attributable to New Growth (Table 3 - Service Area E) = 0.166
Cost of Roadway Facilities Attributable to Growth (2014-2024 - Service Area E):
$172,380,939.75 x 0.166 = $28,615,236.00
City of Wylie—2014 Roadway Impact Fee Update Page 23 of 26 Pa re 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 (2014-2024) 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)
= $28,615,236.00
7,040 ESU
= $4,064.66/ESU= $4,064/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 $4,064 x 50% = $2,032.00.
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$741.00 per service unit (Service Area W)
and $2,032.00 per service unit(Service Area E) are shown on page 17.
