INTRODUCTION The City of Arora retained the services of Birkhoff, Hendricks and Carter, L,L.P for the purpose of updating the impact fees for the water distribution system and the wastewater collection system. These impact fees are required for funding the construction of specific capital improvement projects to serve new development. The table below shows the previous impact fees and impact fee updates calculated and imposed by the City: Since the 2008 update of the Impact Fee, the City of Anna has expanded its water and sewer service. The Water Distribution System Master Plan and Wastewater Collection Master Plan were further prepared in September 2013 by Birkhoff, Hendricks & Carter, L.L.P. and are now consistent with the City's Comprehensive Plan. In accordance with the requirements of Chapter 395.052 of the Local Government Code, this report updates the City of Anna's Land Use Assumptions, Water Capital Improvement Plan and Wastewater Capital Improvement Plan. Chapter 395, of the Local Govermnent Code is an act that provides guidelines for financing capital improvements required by new development in municipalities, counties, and certain other local governments. Based on the most current Master Plan documents for the Water Distribution and Wastewater Collection Systems; 10 -year Capital Improvement Plans were developed to reflect the infrastructure needs in that time period. The accompanying land use plan (Exhibit A) and associated population growth assumptions were also documented based on work by the City Planning Department. From these documents a maximum impact fee is calculated. jAclerickanna\2012-152 w&m, impact Pee update 2012\reports\04-report,docx - 1 - W&WW Impact Fee Update 2014-2024 2008 Calculated Maximum Fee Fees Imposed Water $2,712.50 $2,000 Wastewater $2,643.50 $2,000 Since the 2008 update of the Impact Fee, the City of Anna has expanded its water and sewer service.

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 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 the cost. E. Planning 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 2014 and the year 2024. Facilities in this analysis include, water pump stations, water storage tanks, water transmission lines, water distribution lines, wastewater lift stations, wastewater collection lines, the Slayter Creel-, wastewater treatment plant and the regional wastewater systems. The study period is a ten-year period with 2014 as the base year. The impact fee calculation for the water and wastewater systems is based on land uses provided by the City's Planning Department. The equivalency factors utilized in this analysis conform to the latest American Water Works Association Standards (C700 - C703). jAc1cdcah=a\2012-152 w&vnv impact fee update 2012\repor1s104-repert,docx - 2- W& WW Impact Fee Update 2014-2024 Birkhoff, Hendricks & Carter, L.L.P, II.

LAND USE ASSUMPTIONS (BY THE CITY OFA TNA) The City of Anna Planning Department prepared the Land Use Assumptions for this impact fee update. The separate impact fee Land Use Assumption report is enclosed in Appendix A for reference. 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" means 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". 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 No. 2 below. This same ratio is then used to determine the proportional water and wastewater impact fee amount for each water meter size. jAclerical\anna\2012-152 w&ww impact fee update2012\reports\04-report.docx - 7 - W&WImpact Fee Update 2014-2024 Birkhoff, Hendricks & Carter, L.L.P.

CALCULATION OF WATER & WASTEWATER - LIVING UNIT EQUIVALENTS The City of Anna provided the existing water meter count by size category as of January 2014. In total, there are 3,870 water meters serving the existing population of 10,300 residents and business. Table No. 3 shows the number of existing water meters, the living unit equivalent factor and the total number of living unit equivalents for water accounts. Similarly, the City has provided a count of wastewater accounts as of December 2013. Serving the 10,300 residents, there are 3,279 accounts. Table No. 4 illustrates the existing account and SFLUE's. Using the growth rate provided in the Land Use Assumptions prepared by the City's Planning Department, water meters and wastewater accounts were extrapolated to the year 2024. The City's Planning Department projects the residential and non-residential to grow at the same rate. Living unit equivalents were then applied to the water meters and wastewater accounts for 2014 and 2024 resulting in a total number of living units. The difference in the total number of 2014 and 2024 living units results in the new living unit equivalents during the impact fee period. The calculation of living unit equivalents is summarized in Table No. 3 and Table No. 4. 2014 — 2024 WATER LIVING UNIT EQUIVALENTS BY METER SIZE jAcIcHcabarma\2012-152 w&yw impact tee update 2012\reports\04-r"rt.docx .9— W&WW Impact Fee Update 2014-2024 2014 2024 New Meter Size Number of Water Meters Living Unit Equivalent Ratio for 314" Used Total Number of Living Units Number of Water Meters Living Unit Equivalent Ratio for 3(4" Used Total Number of Living Units Living Units During Impact Fee Period '4 3,768 1.0 3,768 7,071 1.0 7,071 3,303 1" 51 1.7 85 96 1.7 160 75 1%" 5 3.3 17 9 3.3 31 15 2" 41 6.7 273 77 6.7 513 240 3" 1 16.0 16 2 16.0 30 14 4" 3 28.0 84 6 28.0 158 74 6" 1 1 61.3 61 2 61.3 115 L 54 Totals:11 3,870 1 1 4,304 7,262 8,077 3,773 jAcIcHcabarma\2012-152 w&yw impact tee update 2012\reports\04-r"rt.docx .9— W&WW Impact Fee Update 2014-2024 Birkhoff, Hendricks & Carter L.L.P, 2014 — 2024 WASTEWATER LIVING UNIT EQUIVALENTS BY WATER METER SIZE VI.

A. Existing Pnnip Stations, Ground Storage Reservoirs & Elevated Storage Tanks As of 2014, the City of Anna has constructed the facilities listed in Table No. 5. TABLE NO. 5 WATER DISTRIBUTION SYSTEM — EXISTING FACILITIES Facility Capacity Status West Well Pump Station, Ground Storage Reservoir, & Elevated Storage Tank 0.30 MG On -Line North Well Pump Station & Ground Storage Reservoir 0.30 MG On -Line South Well Pump Station & Ground Storage Reservoir 0,30 MG On -Line South Grayson Ground Water Wells 0.91 MGD On -Line South Take Point 4 MGD Off -Line The pump station and ground storage facilities were analyzed with the maximum daily demand, while elevated storage acts dynamically and therefore was 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 planning boundary supplying water to customers in the City of Anna. Lines vary in size from 2 -inch service connections to 18 -inch transmission lines. Normally, a city participates in the construction of water system infrastructure of 12 inches or greater diameter. However, there have been cases in Anna where the City either contracted for new 8 -inch or 10 -inch waterlines to promote development or to support re -development. Careful scrutiny has been given to the distribution system lines that are eligible for capital recovery and in particular, inclusion into the impact fee calculation, jAclerical%mma\2012-152 w&mv bripact fee update 2012\reports\04-report doex - 1 1 - W&WImpact Fee Update 2014-2024 Birkhaf}; Hendricks & Carter, L.L.P. The cost of a waterline includes construction cost, appurtenances (water valves, fire hydrants, taps and the like), utility relocations, purchase of easements and engineering costs. Financing cost over a 20 -year term is included for each project with a 5% annual interest rate. Unit cost for proposed capital improvement water lines 12 inches and larger in diameter were classified as City -initiated water lines and include the full cost of the proposed facility. In some instances, and indicated on the CIP exhibit, water lines will be initiated by the developer. In these cases, the developer will be responsible for the cost of the first 8 -inches and the City will be responsible for the cost associated to construct the line to the size shown on the CIP exhibit. C. Water Supply The City of Anna has 5 ground water wells that produce approximately 2.6 MGD. Additionally, the Collin -Grayson Municipal Alliance (CGMA) supplies treated surface water to the City of Anna, via NTMWD and the City of McKinney. D. Water Distribution System Capital Improvement Projects In order to meet the demands of the anticipated growth over the next 10 -years to 2024, as provided in the Land Use Assumption, certain water distribution system improvements are required. Figure No. 1 shows the recommended system improvements and Table No. 6 itemizes each project and the project cost. These recommended improvements 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 Anna. Where actual costs are not known, an average cost in 2014 dollars has been calculated. The average unit cost is from a limited survey of projects, which have been bid recently, plus an estimated cost for engineering and easements. j:\clericaltanna\2012-I52 w&ww hnpnct fee update 2012\reports\O4-report,docx - 12 - W&WW bnpact Fee Update 2014-2024 Birkhoff, Hendricks & Carter, L.L.P, FIGURE I WATER DISTRIBUTION SYSTEM jAclerical'ianna\2012-152 %v&%%iv impact fee update 2012\reports\04-report docx - 13 - TUffqVImpact Fee Update 2014-2024 Birkhoff, Hendricks & Carter, L.L.P, TABLE NO. 6 10 -YEAR WATER DISTRIBUTION SYSTEM CAPITAL IMPROVEMENT PLAN Water Lines Year Project Size Total Capital Developer Cost (l) Participation Debt Service (2) Total Project Cost Water Line #1 12" $ 2,344,650 $ 1,230,941 $ 3,575,591 Water Line#2 12" $ 1,521,400 X $ 798,735 $ 2,320,135 Water Line#3 12" $ 828,650 X $ 435,041 $ 1,263,691 Water Line #4 12" $ 632,750 X $ 332,194 $ 964,944 Water Line #5 12" $ 1,618,950 $ 849,949 $ 2,468,899 Water Line#6 24" $ 1,_880,800 $ 987,420 $ 2,868,220 Water Lune #7 12" $ 112,500 X $ 59,063 $ 171,563 Water Line #8 12", 24" $ 1,802,150 X $ 946,129 $ 2,748,279 Water Line #9 12" $ 1,604,950 $ 842,599 $ 2,447,549 Water Line#10 12" $ 170,000 X $ 89,250 $ 259,250 Water Line#11 12" $ 1,338,750 $ 702,844 $ 2,041,594 Water Line#12 12" $ 161,200 $ 84,630 $ 245,830 Water Line #13 12" $ 977,050 $ 512,951 $ 1,490,001 Water Line #14 8", 12", 16" $ 2,149,100 $ 1,128,279 $ 3,277,379 Water Line#15 12" 16" $ 2,105,080 $ 1,105,167 $ 3,210,247 Water Line #16 12" $ 776,800 X $ 407,820 $ 1,184,620 Water Line #17 12" $ 433,400 X $ 227,535 $ 660,935 Water Line #18 12111611 $ 762,730 X $ 400,433 $ 1,163,163 Water Line #19 12" $ 255,000 $ 133,875 $ 388,875 Water Line 820 12" $ 2,623,200 $ 1,377,180 $ 4,000,380 Water Lule#21 12" $ 1,059,800 X $ 556,396 $ 1,616,196 Water Line #22 12" $ 996,000 $ 522,900 $ 1,518,900 Water Lune #23 12" $ 4,209,450 $ 2,209,961 $ 6,419,411 Subtotal: Water Lines $ 30,364,360 $15,941,292 $ 46,305,652 jAc1ericallsnna\2012-152 w&%"v impact fee update 2012\reports\04-repurt.ducx -14- W&W lmpaet Fee Update 2014-2024 Bitkhoff, Hendricks & Carter, L.L.R, TABLE NO. 6 (CONTINUED) 10 -YEAR CAPITAL IMPROVEMENT PLAN Facilities Pl tin w F..xnenses Year Proiect Capacity Total Capital Cost (1) Total Water SysteinMaster Plan$ 50,000 Total Water b act Fee $ 35,000 $ - $ 35,000 Capital Developer Debt Project Year Project Capacity Cost (1) Participation Service (2) Cost CGMA Water Supply 1.0 MGD $ 100,000 $ 52,500 $ 152,500 Hackberry EST 0.75 MG $ 2,280,000 $ 1,197,000 $ 3,477,000 1 MG EST 1.0 MGD $ 2,750,000 $ 1,443,750 $ 4,193,750 Initiate South Pump Station $ 500,000 $ 262,500 $ 762,500 Subtotal: $ 5,630,000 $ 2,955,750 $ 8,585,750 Pl tin w F..xnenses Year Proiect Capacity Total Capital Cost (1) Total De -,,eloper Debt Project Participation Service(2) Cost Water SysteinMaster Plan$ 50,000 $ - $ 50,000 Water b act Fee $ 35,000 $ - $ 35,000 Subtotal, $ —85—,0001 $ 85,000 GRAND TOTAL: $ 36,079,360 1 $18,897,042 $ 54,976,402 E.

WASTEWATER COLLECTION SYSTEM A. General At this time, based on the approved Land Use Assumptions for the City of Anna and the expectation for population growth, the City of Anna will approximately double the population in the ten-year period. The most significant growth, that affects the wastewater collection needs of the City, will occur in the Slayter Creek Basin, along the US 75 corridor, and east of SH 5. The wastewater collection system is partially in place to serve the new development. The existing Slayter Creels Wastewater Treatment Plant (WWTP), as well as the Point Of Entry (POE) to the NTWMD system, provide treatment for the sewage. Conveyance from the new developments to these existing facilities will be required. The City of Anna's flow is metered at the WWTP and at two Points of Entry into the regional NTMWD lines. In 2014, the City of Anna maintains the operation of six (6) sewage lift stations with force mains ranging in size from 2 -inch to 8 -inch. Three (3) lift stations are proposed to be constructed during the impact fee period, whereas two (2) existing stations will be taken off-line. B. Collection Lines 1) Existing System: ® Throckinorton Creek 21 -inch Collection: In approximately 2003, the City staff entered into a contract to construct approximately 4,500 linear feet of 21 -inch PVC collection line. This facilitated the construction of single family homes adjacent to FM 455. It also picked up flow from the commercial development located at the intersection of US 75 and FM 455. ® Slayter Creek 24 -inch Collection Line: In approximately 2005, the City staff entered into a contract to construct approximately 7,000 linear feet of 24 -inch PVC collection line. This facilitated the construction of single family homes in the slayter creek basin north of FM 455. jAclericahamna\2012-152 w&ww impact fee update 2012Vepoiis104-mpott.docx -23- w&W Impact Fee Update 2014-2024 Birkhoff, Hendricks & Carter, L.L,P, a Clemmons Creek Point of Entry: In approximately 2005, the City staff entered into a joint contract with the City of Melissa to construct a 15 -inch regional sanitary sewer collector line. The existing line as constructed is approximately one-half mile south of the City of Anna City Limit lines and is not being utilized by the City of Anna today. The extension of this line to the City of Anna, as contracted with the City of Anna, will facilitate growth in the City of Anna east of SH 5. ® Throckinortorl Creek Point of _Entry: In approximately 2009, the City staff entered into a joint contract with the City of Melissa to construct a 21 -inch regional sanitary sewer collector line. A large percentage of the projected growth will be conveyed to the Throekmorton Creek POE. Figure No. 2 illustrates the existing system improvements included in the impact fee calculation. 2) Proposed System Expansion: ® US 75 Corridor: To facilitate opening up the west development area of the City of Anna to meet the intentions of the Land Use Plan, the City will need to invest in collector line infrastructure. Approximately 7,200 linear feet of 12 -inch will be required to collect wastewater from the future residential. The proposed lines will connect to the proposed improvements within the Slayter Creek Basin. ® Slayter Creek Basin: In order for growth to occur in the Slayter Creels Basin, the Throckmorton and Oak Hollow Lift Stations will be required to be taken off-line. A 21 -inch gravity line from the Throckrnorton Creels Lift Station site conveying sewage to the regional NTMWD system will provide capacity for growth within the basin. Additionally, abandoning the existing Oak Hollow Lift Station and replacing with a 12 -inch gravity sanitary sewer will provide additional capacity for growth in the Ferguson Road/County Road 367 area. Figure No. 2 illustrates the proposed system improvements based on meeting the demands associated with the ten-year CIP for the City of Anna. The expectation is jAclecicaBanna\20I2-152 w&ww unpact fee update 2012\reporta\04-report,docn -24- W&WW Impact Fee Update 2014-2024 BirjMojj; Heildricks tt Carter, L,L.P. that each line will be ongincered based on tli(-,, demands associated with the current land use plain and any special circumstances particular to a business or operation that might potentially overload die system due to specific demand issues.

The City also has a public component to consider. The unit for public components was estimated to be 1,000 gpad. 3) Infiltration and Inflow: Groundwater can infiltrate into the sanitary sewer system through faulty sewer pipe joints, breaks in sewer pipes and manholes and faulty service lines. This infiltration creates an average day flow related burden on the wastewater collection system and the wastewater treatment plant. Infiltration is a constant that is not necessarily based on temporary storm based environmental conditions. Normal plant capacity must be designed to handle these infiltration related conditions. The City can embark on programs to rehabilitate lines that contribute significant infiltration volumes when economically and environmentally feasible, and/or desirable. Inflow is generally related to storm based 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 surges could cause surcharged sewers, overflows at manholes and peak flows that surpass the capacity of the treatment plant. It is estimated, for wastewater collection system planning purposes, that the combined infiltration and inflow is 800 gallons per acre per day (gpad) for the existing wastewater collection system and 600 gpad for the new lines proposed in the build -out wastewater collection system. 4) The calculation of peak flows required the development of a unit hydrograph (Diurnal Curve). At the time of this report, a sufficient amount of wastewater flow data was not available to allow for a feasible approach for the development of a diurnal curve specific to the City of Anna. However, unit hydrographs from other cities monitored in the past were evaluated and compiled into a diurnal curve that reasonably represents the peak flow in the City of Anna. This diurnal curve is a unique tool that allows the hydraulic model to simulate a 24-hour cycle that follows the temporal variations in a wastewater system.

CALCULATION OF MAXIMUM IMPACT FEES - 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 the following tables. To simplify collection, we recommend the fee remain fixed throughout the 5 -year period, unless changed by Council.

This land use data provides a basis for determining and scheduling the capital improvements required to serve the existing and fixture population of the City of Anna. This study fulfills the requirements of Chapter 395 of the Texas Local Government Code which prescribes the process by which cities in Texas must formulate impact fees. The purpose of impact fees is to provide an equitable funding method for future capital improvement facilities for: water transmission, distribution, production and storage; wastewater collection, transmission and treatment, and thoroughfares to serve new developments in the City of Anna. These land use assumptions, which also include population, and basic, service, and retail land use projections, will become the basis for the preparation of impact fee capital improvement plans for water, wastewater, and roadway facilities. To assist the City of Anna in determining the need and timing of capital improvements to serve future development, a reasonable estimation of future growth is required. The purpose of this report is to formulate growth and development projections 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. ELEMENTS OF THE LAND USE ASSUMPTIONS REPORT This report contains the following components: I. Methodology -- Explanation of the general methodology used to prepare the land use assumptions. II. Data Collection Service Area Maps (Figures 1, and 2) -- Explanation of division of the City into impact fee service areas for roadway, water and wastewater facilities. III. Base Year Data -- Information on population, employment, and land use for Anna as of 2014 for each capital facility service area. IV. Ten -Year Growth Assumptions -- Population and employment growth assumptions for ten years by impact fee service areas. V. Summary -- Brief synopsis of the land use assumptions report. Page 2 of 14 I. METHODOLOGY Based upon the growth assumptions and the capital improvements needed to support growth, it is possible to develop an impact fee structure which fairly allocates 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. These land use assumptions and future growth projections take into consideration several factors influencing development patterns, including the following: • The character, type, density, and quantity of existing development • Existing zoning patterns • Anticipated future land use (as shown on the City's Future Land Use Plan) • Availability of land for future expansion • Current and historical growth trends within the City • Building permit activity trends • Basic, Retail, and Service land use absorption rates • Physical holding capacity of the City • Known or anticipated development projects Following is the general methodology used for the preparation of this report: 1. Update impact fee service areas as necessary for roadway, water and wastewater facilities (see Section H -- Service Area Maps). 2. Collect/determine benchmark data on population, basic, retail and service land use as of 2014 (see Section III-- Base Year Data). 3. Project population and basic, retail and set vice land use growth for ten years by impact fee service area (see Section IV -- Ten-Year Growth Assumptions). More detailed discussion for each of the above is contained within the respective sections. Page 3 of 14 11. SERVICE AREA MAPS Service Area Maps Figure 1, entitled "Roadway Impact Fee Service Area Structure", details the nine (9) service areas for roadway facilities. Although the capital improvements plan and impact fees will be prepared as a separate document for roadway facilities, the geographic boundaries of the roadway service areas are shown as Figure 1. Figure 2 show the service areas for water and wastewater facilities. The boundary for water and wastewater facilities service area is the combination of the existing city limits and the extraterritorial jurisdiction. Documents containing the capital improvements plan for water and wastewater facilities will also be prepared separately. Data Format The existing data base, as well as the future projections, was formulated according to the following format and categories: Service Area Correlates to the proposed roadway, water and wastewater service areas identified on the attached maps. Housing Units (2014) All housing units including single-family, duplex, multi -family and group quarters. The number of existing housing units has been shown for the base year (January 1, 2014). Housing Units (2024) Projected housing units by service zone for January 2024 (ten-year growth projections). Population (2014) Existing population for the base year (January 2014). Population (2024) Projected population by service area for the year 2024 (ten-year growth projections). Employment (2014, 2024) Employment data is aggregated to three employment sectors and include: Basic, Retail and Service. The following details which North American Industry Classification (NAIC) codes fall within each of the three sectors. Basic (#210000 to 4422999) -- Land use activities that produce goods and services such as those that are exported outside the local economy; manufacturing, construction, transportation, wholesale trade, warehousing and other industrial uses. Retail (#440000 to #454390) -- Land use activities which provide for the retail sale of goods that primarily serve households and whose location choice is oriented toward the household sector such as grocery stores, restaurants, etc. Service (1{520000 to #928199) -- Land use activities which provide personal and professional services such as financial, insurance, government, and other professional and administrative offices.

This "benchmark" information provides a starting basis of data for the ten-year growth assumptions that will be presented within the following section. Population Growth The existing and past population levels for Anna are depicted in Table 1. As indicated, between 1940 and 2010 the population growth has been substantial, increasing from 509 persons in 1940 to 8,249 persons in 2010. The 2013 estimated population estimated the North Central Council of Governments is 9,360 persons, which represents a significant increase (13.5%) since the 2010 estimate. Currently, the total population is estimated to be 10,300 based on the housing count prepared in this report. This estimate uses an average household population of 3.15 and an occupancy rate of 94 percent. Additionally, within the City and the ETJ the population is estimated to be over 13,632 persons.

TEN-YEAR GROWTH ASSUMPTIONS Growth is characterized in two forms: population (residential land use) and employment (nonresidential land use). A series of assumptions were made to arrive at reasonable growth rates for population and employment. The following assumptions have been made as a basis from which ten-year projections could be developed. _ Future land uses will occur as identified on the Future Land Use Plan adopted in 2010 with updates The City will be able to finance the necessary improvements to acconnmodate growth, School facilities will accominodate increases in population, and Densities will be as projected as detailed in the Comprehensive Plan. The ten-year projections, or land use assumptions, are based upon the establishment of a reasonable growth rate which is based upon past trends or other considerations. Given the impact on growth due to the economic fluctuations in the late 2000's, analysis of annual growth based on data from building permit data and U.S. Census was undertaken to provide further insight into growth trends experienced within the City. The single-family building permit activity since 2005 in Anna has fluctuated with time, going from 506 in 2005 to as low as 7 in 2009. Table 3 represents this fluctuation in growth and the data used to find the average number of permits over the nine-year period, of 232 building permits. Several different scenarios were produced to estimate the future population using a range of building permits from 200 to 300 and also percentage increases of 6, 7 and 9 as shown in Table 4. The scenario that best fits the last two years of building permits and the anticipated growth is the 7 percent therefore it was the growth rate used for this analysis.

However the growth was not projected to occur evenly throughout the roadway service areas of the city. While growth will generally occur throughout the city, the current city staff provided knowledge of the key growth areas within the community. Many new developments are in the planning phases with preliminary plats being currently submitted. The following is a list of the major projects interests: • Lake View Preliminary Plat —168 lots • West Crossing Phase 4 — Final Plat Construction Plans under review — 70 lots • Anna Crossing Phase IA & 1B Preliminary Plat — 175 lots • Anna Crossing Phase I Construction Plans under review • Anna Crossing Phase 2A Constriction Plans under review — 59 lots • Discussions on future phase of North Point Crossing — 498 lots • Discussions on Villages of Hurricane Creek — 1,008 lots • Discussions on Oak Ridge — 2,635 lots Page 10 of 14 Other conversations with developers are occurring regularly on other large land holdings. The ten-year population estimates were determined by growing service areas to represent current development patterns while also maintaining the 7 percent overall growth rate. The household growth figures are shown by roadway service area in Table 5.
