WORK SESSION 1. Work Session on Land use Assumptions, Capital Improvements Plan, and modification of impact fees. Staff Comments Mr. Porter approached the Commissioners, gave a brief summary on the purpose of the work session, stating that impact fees are typically considered every four to five years and have previously been. staggered between roadway and utility studies every two years. This year Mr. Porter decided to review and update the roadway impact fees and the water and wastewater fees at one time. Minutes July 16,2019 Impact Fee Advisory Committee Page 1 Mr. Joe Carter, Birkhoff, Hendricks and Carter, LLP, Dallas, Texas, the consultant, stated that for the Water and Wastewater improvements, the City of Wylie is allowed to collect fees on projects that contribute to growth and require additions to the current public systems. The developers currently pay 50 percent of the allowable maximum. Mr. Porter encouraged the Commissioners to review the current water and sewer cost, and roadway cost from the City of Wylie website under the Engineering Department. Currently, the roadway rates are the same for the east and the west. One reason the proposed rates are higher is due to construction cost increases. Water and Wastewater fees are one rate city wide and the roadway fees are separated by the east and west sides of the City of Wylie, which is required by the State Law based on service area. The next meeting for the Impact Fee Advisory Committee is August 6, 2019, to make a recommendation to the City Council. ADJOURNMENT Chair Ron Smith adjourned the meeting at 7:22PM.

INTRODUCTION 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: Fee Per Service Unit Calculated Fees Imposed Maximum (Ordinance 2011-11) Water $3651.42 $3651.42 Wastewater $773.48 $773.48 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 j:Acler cal\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact feeAreports\03-repart.doc -1 - Birkhoff,Hendricks&Carter,L.L.P. 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). j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc -2- Birkhoff,Hendricks&Carter,L.L.P.

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. j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc -7- Birkhoff,Hendricks&Carter,L.L.P. C. Methodology 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. j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc -8- Birkhoff,Hendricks&Carter,L.L.P. 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. j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc -9- -ram e.

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. Table 1 HISTORICAL GROWTH RATE City of Wylie, Texas Compounded Year City of Wylie % Change Average',Annual /o Change per Period 1970 (1) 2,675 0.00% 0.00% 1980 (1) 3,152 17.83% 1.65% 1990 (1) 8,716 176.52% 10.71% 2000 (1) 14,965 71.70% 5.55% 2010 (1) 41,427 176.83% 10.72% 2018 (2) 52,003 25.53% 2.88% (') Source: U.S. Census. (2) Source: Current Population Estimate, Provided by City Staff. 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. j:Acler cal\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact tee Areports\03-repart.doc - 1 1 - Birkhoff,Hendricks&Carter,L.L.P. 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. Table 2 RESIDENTIAL BUILDING PERMITS PER YEAR City of Wylie, Texas Year Prior Total Residential Units New Residential Units % Growth 2013 15,024 (1) 250 1.7% 2014 15,274 (1) 298 2.0% 2015 15,572 (1) 542 3.5% 2016 16,114 (1) 447 2.8% 2017 16,561 O 567 3.4% 2018 17,128 (1) 600 3.5% Average: 451 new residential units per year over 6 years l>> 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:Acler cal\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact tee Areports\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.

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:Acler cal\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact feeAreports\03-repart.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 Populations and Growth Rates of Area Cities and Collin County—2010 to 2018 Compounded Average City/Jurisdiction 2010 2018 Annual % Population Population Change (2010-2018) Wylie 41,427 52,003 2.88% Allen 84,253 96,870 1.76% Frisco 116,989 172,940 5.01% McKinney 131,117 179,970 4.04% Murphy 17,708 20,010 1.54% Plano 259,841 281,390 1.00% Prosper 9,423 22,650 11.59% Collin County 782,341 969,730 2.72% Source: U.S. Census, 2010 and 2018 Population Estimates, North Central Texas Council of Governments (2018). j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact tee Areports\03-repart.doc - 16- Birkhoff,Hendricks&Carter,L.L.P. 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. j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc - 17- Birkhoff,Hendricks&Carter,L.L.P. Table 6 shows the additional Retail/Office, Commercial, and industrial land uses required for the increase in population projected through 2028 (6,670 people). TABLE 6 TEN-YEAR LAND USE PROJECTIONS --2028 For The Water Service Zones—2028 City of Wylie, Texas Future Acres Acres Required For Land Use Per 100 Persons 6,670 Persons Commercial/Retail/Office 1.80 120 School, Public/Semi-Public, Services 0.67 45 Utilities, Heavy and Light Industrial 2.50 167 Parks & Open Space 1.03 69 Total Acres: 6.00 401 Source: City of Wylie, April 2005. 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 Projection 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. j:Acler cal\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact tee Areports\03-report.doc - 18- Birkhoff,Hendricks&Carter,L.L.P. 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 43,147. 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. j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc - 19- Birkhoff,Hendricks&Carter,L.L.P. IV. DEFINITION OF A SERVICE UNIT — WATER AND WASTEWATER 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.

V. CALCULATION OF WATER& WASTEWATER- LIVING UNIT EQUIVALENTS 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. j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc -21 - Birkhoff, Hendricks&Carter, L.L.P.

VI. WATER DISTRIBUTION SYSTEM 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 Table 10 outlines a summary of the City's existing water facilities. TABLE 10 Water Distribution System--Existing Pump Stations & Ground Storage Total Number of Total Number Rated Ground Ground Storage of Capacity Storage Available Pump Station Pumps (MGD) Tanks (Gallons) Nortex 5 9.20 2 2,500,000 East Brown 5 10.64 1 1,500,000 Newport Harbor 4 11.73 1 2,000,000 Total: 4 6,000,000 Elevated Storage Tanks Capacity in Gallons Creekside Elevated Storage Tank 2,000,000 South Ballard Elevated Storage Tank 250,000 Regency(Decker) Elevated Storage Tank 750,000 Total 3,000,000 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:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact tee Areports\03-repart.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 Lewisville 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 j:Acler cal\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc -24- 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. j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc -25- EXISTING NEWPORT HARBOR PUMP STATION r.'------------I • GSR#1 (EWF-1) I • PUMP STATION CREEKSIDE 2.0 MG = 1 (EWF-2) ELEVATED STORAGE TANK • PROPOSED GSR#2 (EWF-9) =;' _. - (PWF-2) „ 1 EL6 EL2 ,,,,;„ , t6 � i --: w 1 ,' L11 EL3 _ 297/1 p WYLIE 16" 4 m 10 .

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.

VIL 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:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\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. j:Aclerical\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact fee Areports\03-report.doc -35- 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. Noziiial plant capacity must j:Acler cal\wylieA2018-118 w&ww-thoroughfare-impact fee\cip&impact feeAreports\03-repart.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 stoup 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.

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 IB 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.

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, 10th 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 infoi oration 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.

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.

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.

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) = $4,769,887.15 2,608 ESU = $1,828.94 /ESU= $1,828 /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 $1,828 x 50% = $914.00. Calculation for Service Area E Cost of Roadway Facilities (Tables I A and 1 B - 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 $4,633 x 50% = $2,316.50. 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$914.00 per service unit (Service Area W) and $2,316.50 per service unit (Service Area E) are shown on page 17.

The 2019 Max Allowable rate would be substantially higher than the 2014 fee that is presently being used. 2. The 2014 Fee of$400 per service unit was established with the East&West zones to be the same. * I would like to see this stay the same to keep development opportunities Equal in Wylie and not hinder the East over the West. 3. I would also think with the service units being increased in the 2019 report vs 2014 report would create the following. * Increase the burden on any developer or business owner wanting to move their business to Wylie? * Stifle growth opportunities in Wylie 4. I would like to know the basis of why the service units increase. 5. I would recommend the rate of$400-$500 per service unit be considered in leu of max rate.
