INTRODUCTION Chapter 395 of the Texas Local Government Code allows for the financing of capital improvements by municipalities through the implementation of impact fees. The land use assumptions and capital improvement plans utilized to develop the roadway impact fees must be reviewed and updated every five (5) years. The update of the impact fees is performed following these basic steps: 1. Development of land use assumptions to identify types and intensities of land use within the City. 2. Development of a Capital Improvement Plan to include improvements planned for the next 10 -year period to accommodate growth in the City. 3. Development of the calculated and the rnaxinnan impact fee. II. LAND USE ASSUMPTIONS One of the initial steps in developing roadway impact fees includes the identification of data related to the planned land uses for land within the City of Anna city limits. The land use data provided by the City of Anna included projected growth by land use type and the locations they are expected to occur over the next 10 years (2018-2028) and at build -out. A summary of the land use data provided for the land within the city limits of Anna is provided in Table 1.

ROADWAY IMPACT FEE SERVICE AREAS For the purpose of roadway impact fees, the roadway service area is limited to the now current City Limits. Additionally, the roadway service areas can not extend in any direction more than 6 -miles. The City's' original roadway impact fee calculation and report identified and defined two (2) roadway services. These service areas are generally divided by State Highway 5 (Powell Parkway) and are shown in Figure 1. f►lN\�Yr�A1►�IT�]�I�1►\I1`►Mr1I_\►1 After the land use assumptions within the City have been identified, and with the help of the City's Thoroughfare Plan, a 10 -year Capital Improvement Plan (CIP) is developed. This capital improvement plan includes projects intended for construction by the City of Anna in the next 10 years to serve both existing and future development. In order to be funded by roadway impact fees, a roadway project must be included in the 10 -year CIP. Existing Facilities The City of Anna major roadway and 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. Many of the proposed roadway segments on the thoroughfare plan do not currently exist. The existing major roadways within the City include US Highway 75 (US 75), State Highway 5 (SH 5)/Powell Street, FM 455/White Street, and SH 121. Existing major collectors include segments of Rosamond Parkway and Ferguson Parkway. The major roadways identified above (US 75, SH 5, FM 455, and SH 121) are under the operation and maintenance jurisdiction of the Texas Department of Transportation (TxDOT). Proposed Facilities The City of Anna adopted a Comprehensive Plan in 2010, including a thoroughfare plan 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 Major Roadway 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 developments. The character of the developments served should determine the sizes and alignments of collector roadways. j:jclerical�onno�2018-137 Roadway impact fee�reports�03-report Page 2 of 13- Roadway Impact Fee Update 2018-2028 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 2 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 2018 CIP are identified in the City of Anna Thoroughfare Plan. j. �clericaAanno�2018-137 Roadway impactfeelreportsJ03-report Page 3 of 13- Roadway Impact Fee Update 2018-2028 N'.

The project costs are based on data provided by the City of Anna and on roadway project construction bids. Costs of these projects included only those costs that will be paid for by the City of Anna. Financing costs for the projects in the CIP were also included in the total estimated cost and the interest rate of 5% was provided by the City of Anna. V.- IMPACT FEE CALCULATION After the land use assumptions and CIP have been finalized, this information is used to determination the maximum fee per service unit (impact fee) 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 (CII') by the number of service units of growth forecast to occur (using the land use assumptions). 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. Analysis of the total capacity, level of current usage, and commitment for usage of capacity of existing improvements; 4. Identification of that portion of the total capital improvements necessary to serve the projected growth over the next 10 -year period; 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; 6. Calculating the resulting eligible costs per service unit (impact fee) for new developments in each service area. 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 peals 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, 9t" 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 j. �clericaAannaJ2018-137 Roadway impactfee�reportsJ03-report Page 6 of 13- Roadway Impact Fee Update 2018-2028 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 Anna. Table 3 shows the typical service units for each land use type used in developing the roadway impact fees. Table 3 - Service Unit Calculation by Land Use Type (1) Based on ITE Trip Generation Manual, 9th Edition (2) Based on NCTCOG data 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 (Service Area 1 and Service Area 2) were established for the City of Anna to ensure that funds are spent within six miles of where they are collected. The two service areas were shown in Figure 1, with SH 5/Powell Avenue serving as the breakpoint between the two service areas. The service areas include most of the developable land within the existing city limits of Anna. Analysis of 10 -Year and Ultimate Growth The land use assumption data provided by the City of Anna was converted to the standard service unit (vehicle -miles) by applying the trip generation and trip length data provided in Table 3. These results were used to provide an estimate of the existing service units (vehicle -miles) within each service area, as well as to forecast the growth in set -vice units for both the next 10 -year period (2018- 2028) and the ultimate development of the City of Anna. Table 4a shows the vehicle -mile calculation for each category of land use. Table 4b shows the portion of ultimate build -out service units that will be attributable to growth within the next 10 years. j. �clericoAanno�2018-137 Roadway lmpactfee�reportsJ03-report Page 7 of 13- Roadway Impact Fee Update 2018-2028 PM Peak Trips Trip Length PM Peak Hour Variable (vehicles) (miles) Vehicle -Miles (1) (2) Residential Dwelling Unit 1 3.00 3.00 Industrial 1,000 Sq.

As an alternative to performing the financial analysis, the impact fee can be set at or below 50 percent of the total eligible costs, which are shown in Table 7. The City has chosen to use 50 percent of these calculated impact fee. VI. SUMMARY OF IMPACT FEE CALCULATION METHODOLOGY The methodology for calculating the maximum allowable impact fee for roadway facilities can be summarized in the following three steps and is summarized for both Service Areas 1 and 2 on the following pages. First, 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 is determined. j: �clericoljanna�2018-137 Roadway impactfee�reportsJ03-report Page 10 of 13- Roadway Impact Fee Update 2018-2028 Maximum Impact Fee Calculation for Service Area 1 Cost of Roadway Facilities (Table 2- Service Area 1) _ $185,198,286 Proportion of Capacity Attributable to New Growth x 15.46% (Table 4- Service Area 1) Roadway Facilities Attributable to Growth (2018-2028) _ $28,627,660 The second step is to determine the 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 (2018-2028) divided by the total growth in equivalent service units (ESU). Finally, the maximtun impact fee is determined by multiplying the calculated fee by 50%.

IMPACT FEE CALCULATION EXAMPLE A land use equivalency table is provided in Table 8 and represents an expansion of the basic land uses used for calculating the impact fee. This table identifies the total service units generated by specific uses within each land use category and includes land uses which may develop over the next 10 -year period. 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 8 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 maximum allowable impact fees of $905.00 per service unit (Service Area 1) and $842.00 per service unit (Service Area 2) are shown on page 12 Table 8 - Common Roadway Land Use Equivalencies (CATEGORY LAND USE DEVELOPMENTUNITS(1), ITE TRIP RATE(2) TRIP LENGTH(3) PASS-BYTRAFFIC(4)I SERVICE UNITS(S) Single- Family Detached Dwelling Unit 1.00 3.0 0 3.00 Apartment Dwelling Unit 0.62 3.0 0 1.86 Office Building 1, 000 ft GFA 1.49 3.0 0 4.47 COMMERICAL Convenience Stores/Gas Pumps 1,000 ft GFA 50.92 0.4 0.66 6.93 Drive-in Bank 1,000 ft GFA 24.30 1.7 0.47 21.89 Home Improvement Store 1,000 ft GFA 2.33 3.0 0.48 3.36 Hotel Rooms_ 0.60 _ 3.0 0 1.80 Restaurant 1, 000 ft GFA 9.85 2.4 0.43 13.47 Shopping Center 1,000ftGFA 3.71 3.0 0.34 7.35 INDUSTRIAL Industrial 1,000 ft GFA 0.97 3.0 0 2.91 INSTITUTIONAL School Students 0.15 2.1 0 0.32 Day Care Center Students 0.81 2.7 0.9 0.22 House of Worship 1, 000 ft GFA 0.55 2.1 0 1.16 ' GFA = Gross Floor Area a (Vehicles); Based on ITE Trip Generation, 9th Edition (Miles); Based on NCTCOG Data Percentage of traffic already passing by site - land use is an intermediate destination (Vehicle -Miles) * The land uses and trip generation characteristics listed in this chart are intended as examples.
