The service area is located just west of Wellborn Road between FM 2818 (Harvey Mitchell Parkway) and Rock Prairie Road. Water Service Area "03-01", as shown in Exhibit 2, consists of approximately 434 acres of agricultural, low and medium density residential, scatter retail, and institutional uses. The land use assumptions, as shown herein, are based on the City's Comprehensive Land Use Plan and the history of development in this portion of the City for the past eight years. Projecting the average growth over the past eight years to the next ten year period c03-`13) would result in the addition of approximately 525 new single family dwelling units to the Water Service Area "03-01". Medium density residential, which compromises most of this area, has been estimated at 4 dwelling units per acre. This accounts for 440 of the new single family dwelling units added. The remainder of the new dwelling units comes from the transitional area land use. This transitional area is anticipated to develop as either retail or residential. For the purposes of this report, half of these transitional areas have been projected to develop as attached residential with 13 dwelling units per acre, and the remainder as commercial. No high density developments are anticipated in the "03 -01" service area. Commercial and retail properties at the intersection of Cain Road and Wellborn Road as well as those at the intersection of Gandy Road and Wellborn Road are anticipated to build out in the first ten year ('03 -' 13) growth window. Additional retail and commercial properties further away from these main intersections are projected to develop in the second ten year ('13-'23) period. Due to unknown rail and SH40 alignments, it is anticipated that a small percentage of the industrial tracts along FM 2818 will develop in the first ten year growth window. Industrial land use areas at the intersection of Gandy and Wellborn Road are already platted, and some development has already commenced. This area is expected to develop fully in the first ten year period ('03 -' 13). It is believed that smaller transitional land use tracts in the service area will also develop in the first ten year period ('03- `13). The Capital Improvement Plan for Water Service Area "03 -01" was developed using the Land Use Assumptions for the service area as seen on Exhibit 3. The water lines that will be extended to serve this area consist of approximately 10,227 linear feet of 16 -inch DIP water line. These water lines are located such that they will serve the entire "03 -01" service area as seen in Exhibit 4. The preliminary cost estimate for these waterlines is $2,132,625. These costs include engineering and design, land acquisitions, and construction costs. The costs calculated for the improvements must be reduced by the utility service revenues used to repay the debt service generated by new service units. These fees are then proportioned by the ratio of new Living Unit Equivalents (LUE's) to the total Living Equivalents served. This calculation results in the maximum allowable impact fee per unit. Below are the estimated eligible cost, cost allocation factor, maximum 10 -year recoverable cost, utility revenue and ad valorem tax credits, and maximum impact fee allowable for Water Sewer Service Area "03-01". /1-litcheII &/korgan, LLP - 2 - Estimated Eligible Cost Construction Cost $1,733,309 Engineering /Survey /Geotechnical $276,029 Land Cost $106,887 Impact Fee Preparation $16,400 Total Eligible Cost $2,132,625 Cost Allocation Total New LUE's 2441 Total LUE's Served 2777 Cost Allocation Factor 2441/2777 = 0.88 Maximum Recoverable Cost 0.88 *$2,132,625 = $1,876,710 Maximum 10 -Year Recoverable Cost Projected LUE's 2003 -2013 1110 Projected LUE's after 2013 1331 Total New LUE's 2441 Service Distribution % 100 *(1110/2441) = 45% Maximum 10 -Year Recoverable Cost 45% *$1,876,710 = $844,520 Utility Revenue Credits & Ad Valorem Tax Utility Revenue per LUE Applied to Capital Improvements $39.26 Total Utility Revenue Credit' $39.26* 1110 = $43,579 Ad Valorem Tax Applied to Capital Improvements $0 ' Revenue credit on new LUE's associated with first 10 -year ('03-'13) growth window (service time frame) /Mitchell &/Morgan, LLP - 3 - Number of New LUE's" 1110 Impact Fee Calculation Maximum Impact Fee = Maximum 10 -Year Recoverable Cost — Total Utility Revenue Credit Number of new LUE's Maximum Impact Fee = ($844,520- $43,579)/(1110 LUE's) = $721.57/LUE " Number of new LUE's associated with 10 -year growth window ('03 -' 13) Mitchell &/Llorgan, LLP - 4 - Water Service Area "03 -01 Steeplechase/Wellborn Road Area October 2003 Land Use Assumptions Existing Land Use The Steeplechase /Wellborn Road Area designated as Water Sewer Service Area "03 -01" (Exhibit 1) consists of approximately 434 acres of agricultural, residential, commercial and a small portion of industrial and institutional property. This area has been targeted as an impact fee area due to the recent College Station annexation of the property and the rapid growth that has occurred along the Wellborn Road corridor over the past 10 years. In order to assess impact fees for new water infrastructure an evaluation of the existing and future land uses for the area had to be completed. Exhibit 2 illustrates the existing land uses that were found in the "03 -01" area while Table 1 illustrates the acreages associated with Exhibit 2. Table 1 Existing Land Use (Year 2003) Land Use Gross Acres Agricultural/Vacant 201 Rural Density Residential ( <1/3 d.u. /acre) 166 Low Density Residential (1/3 - 2 d.u. /acre) 43 Medium Density Residential (3 — 6 d.u. /acre) 0 High Density Residential (7 — 9 d.u. /acre) 0 Residential Attached (10 — 20 d.u. /acre) 9 Retail Regional 12 Retail Neighborhood 0 Industrial 1 Institutional 2 TOTAL 434 /Mitchell &/Morgan, LLP - 5 - Future Land Use: Ultimate Development The future land use assumptions for the area are based on the approved City's Comprehensive Land Use Plan, an excerpt of which can be seen in Exhibit 3. Heavy residential development has been occurring in the Edelweiss and Steeplechase Subdivisions along Wellborn Road just south and east of the subject area. Development in this general area began seriously in 1989 and has progressed steadily since. At present, the residential portion of the Edelweiss and Steeplechase Subdivisions are almost fully developed, with the commercial tracts of the development slowly filling in. The growth in these areas has added over 700 new single- family dwelling units over the past eight years. Projecting this same growth rate through the first ten year period (`03-`13) for the subject area will result in approximately 525 new single - family dwelling units. It is assumed that the transitional land use shown on Exhibit 3 will develop as half attached residential at 13 dwelling units per acre, and half as commercial density at 10 dwelling units per acre. Medium density residential is assumed to develop with a density of 4 dwelling units per acre. The service area has been determined based upon the recent annexation boundary, the existing Certificate of Convenience and Necessity (CCN) area, and the current contract between the City of College Station and the Wellborn Special Utility District. It is anticipated that in the first ten year window ('03-'13) that the bulk of medium density residential development will occur along Cain Road, with the remainder along Gandy Road. Current residential development in these areas is increasing, and continuing growth is expected. Future Land Use: 10 year Growth Projection Development of the residential land use categories and transitional land use categories shown in Table 2 will result in approximately 525 new single - family dwelling units being added to the Water Service Area "03-01". Current development in the Steeplechase Subdivision and Fraternity Row has built out in a similar fashion, and has nearly reached its ultimate buildout for the higher density residential categories. Due to the recent rapid nature of the buildout of attached, high, and medium density residential in these areas, it is reasonable to assume that once sanitary sewer and water is available to the "03 -01" area that this type of housing will rapidly develop in the "03 -01" area as well. Commercial and retail properties at the intersection of Cain Road and Wellborn Road as well as those at the intersection of Gandy Road and Wellborn Road are also anticipated to build out in the first ten year ('03 -' 13) growth window. Additional retail and commercial properties further away from these main intersections are projected to develop after the ('03 -' 13) period. It is difficult to predict the timing for the development of the industrial use property at the corner of Wellborn Road and FM 2818 (Harvey Mitchell Parkway). Due to the unknowns associated with the TxDOT SH40 alignment and the ongoing discussion regarding the Wellborn Road rail relocation, these tracts may not consolidate and develop for some time. However, it is just as Mitchell &/Ltorgan, LLP - 6 - likely that an aggressive developer could build on these tracts immediately without concern for the unknowns associated with these major transportation issues. If that is the case, the infrastructure will be in place to support such a development. However, it is more likely that only a small percentage (7 acres or 15 %) of the industrial tracts along FM 2818 will develop in the first ten year growth window ('03-'13). Industrial land use areas at the intersection of Gandy and Wellborn Road are already platted, and some development has already commenced. This area is expected to develop fully (33 acres) in the first ten year period ('03-'13). The remainder of the industrial development in the "03 -01" service area is projected to take place after this first ten year growth period ('03-'13). This service area includes a unique land use labeled as "transitional ". This category has been used to identify areas that could reasonably develop as residential attached or as commercial /retail uses. For calculations, the transitional areas were assumed to develop as one- half residential attached and as one -half commercial /retail land use. This additional land use category was added to this area to allow flexibility for those tracts affected by the unknowns associated with the SH40 alignment and possible rail relocation. It is anticipated that approximately 13 acres or approximately 25% of the transitional land use tracts in the service area will develop during the first ten year period ('03-`13). The remainder of the transitional area will most likely take additional time to develop as the property owners wait to see the results of TxDOT's work in the area. The transitional land use category consists of a combination of commercial /retail and residential attached properties. The land uses and acreages that are projected to develop within the first ten year window ('03- ' 13) for Water Service Area "03 -01" are shown in Table 2. //Mitchell &//organ, LLP - 7 - Table 2 Water Service Area "03 -01" Growth Projections (2003 -2013) Land Use Gross Acres* Rural Density Residential ( <1/3 d.u. /acre) 0 Low Density Residential (1/3 - 2 d.u. /acre) 0 Medium Density Residential (3 — 6 d.u. /acre) 110 High Density Residential (7 — 9 d.u. /acre) 0 Residential Attached (10 — 20 d.u. /acre) ** 0 Retail Regional 6 Retail Neighborhood 6 Industrial 40 Institutional 0 Transitional** 13 Parks 10 Mixed Use 0 SH40 ROW 11 TOTAL 196 *Acreages throughout do not make allowances for street rights -of -way, therefore the reduction of developable land due to these is taken into account through densities as described on page 13. * *Although not an individual area on the land use plan, residential attached is assumed to buildout as one -half of the development within transitional land use areas. The remaining half of transitional areas is assumed to develop as commercial/retail properties. /kitchell &/Llorgan, LLP - 8 - The land uses and acreages that are projected to develop beyond the first ten year window (2003- 2013) for the Water Service Area "03 -01" are shown in Table 3. These two growth projection windows are important to understand due to the fact that the impact fees must be assessed based upon the growth that will initially occur within a "reasonable period of time" defined within impact fee legislation as ten years. This future growth which will likely occur after the year 2013 may be assessed impact fees as the impact fee report is updated every 3 -5 years and the growth window for the area shifts, resulting in the recalculation of the fees based upon a new growth scenario.

Mitchell &/Morgan, LLP - 9 - Capital Improvement Plan Water Service Area "03 -01 Existing Water Facilities The Water Service Area "03 -01 ", as previously discussed is shown on Exhibit 1. This service area is located adjacent to and west of Wellborn Road between FM 2818 and Rock Prairie Road. Water service to this area is provided through an existing thirty -six inch (36 ") water line along Wellborn Road. This water line carries water from the Dowling Road Pump Station located adjacent to Water Service Area "03 -01" to the southern portion of College Station. Cost recovery related to the water wells and pumps are not being considered within this service area at this time. Projected Water Facilities: Ultimate Development The waterlines that will be extended to serve this area consist of three sixteen (16 ") inch DIP distribution lines along Marion Pugh Drive /Abandoned ROW, Cain Road, and Gandy Road. The southern most waterline is approximately 5668 linear feet and runs parallel to Marion Pugh Drive /Abandoned ROW from Saddle Lane to 1132 linear feet south of Cain Road. This waterline is connected to the north to an existing forty -two (42 ") inch waterline and to the south to the proposed waterline parallel to Cain Road. The waterline parallel to Cain Road is approximately 3170 linear feet connecting to the proposed Marion Pugh Drive /Abandoned ROW to the south and to an existing thirty -six (36 ") inch waterline to the north at the intersection of Navarro Dive and Wellborn Road /FM 2154. The remaining line connects to an existing thirty -six (36 ") inch waterline at the intersection of Rock Prairie Road and Wellborn Road /FM 2154 and ends approximately 1926 linear feet south, parallel to Gandy Road. It is anticipated that these improvements will be designed and constructed under one contract. These three waterlines are located such that they will serve the entire "03 -01" service area, as seen in Exhibit 4. The preliminary estimated project cost is $2,132,625 which is based upon the following estimate shown in Table 4. These costs include engineering and design, land acquisition, and construction. Although state law permits the inclusion of interest charges and other financing costs in the capital improvements plan, such costs have not been included in this report. Because project costs are to be adjusted through the amendment process mandated by state law, no inflationary factors have been included in the project estimates.

Projected Water Facilities: 10 -Year Growth Projection State law limits the City to collection of the infrastructure costs necessary to service a time frame not to exceed ten years. Service distributions, as seen later in this report, allow the City to comply with state law without having to construct a smaller water line and then return 10 -15 years later to construct a parallel water line to accommodate the increased demand of ultimate development. The line needed to serve the first ten year projected growth window is a sixteen inch (16 ") waterline. Mitchell &Morgan, LLP - 11 - Service Unit Determination The City of College Station has selected the Living Unit Equivalent as the appropriate measure of water service consumption by new development in their impact fee areas. The same has been chosen for Water Service Area "03-01". As used in the Capital Improvement Plan, a "service unit" is defined as a single - family residence without regard for the number of bedrooms. A 5/8- inch water meter is the typical size water meter serving a single- family residence in the city. The 5/8 -inch meter is considered one unit. Other meter sizes are proportioned Living Unit Equivalents according to their flow relationship to the 5/8 -inch meter. Living Unit Equivalents for residential structures are shown in Table 5, while those for non - residential structures are shown in Table 6. Table 5 Living Unit Equivalents Residential Structures Type of Structure Unit L UE Single Family Dwelling Structure 1 (all sizes /no. of bedrooms) Duplex Duplex 2 (all sizes /no. of bedrooms) Triplex Triplex 3 (all sizes /no. of bedrooms) Fourplex Fourplex 4 (all sizes /no. of bedrooms) Multi- family (one and two bedroom units) Unit 0.75 (three and more bedroom units) Unit 1 Mobile Home Mobile Home 0.75 /Mitchell &/Morgan, LLP - 12 - Table 6 Living Unit Equivalents Non - Residential Structures Meter Size L UE /Meter Size 5/8 inch simple 1 3/4 inch simple 1.5 1 inch simple 2.5 1-1/2 inch simple 5 2 inch simple 8 2 inch compound 8 2 inch turbine 10 3 inch compound 16 3 inch turbine 24 4 inch compound 25 4 inch turbine 42 6 inch compound 50 8 inch compound 80 6 inch turbine 92 10 inch compound 115 8 inch turbine 160 10 inch turbine 250 12 inch turbine 330 Projected Growth of Living Unit Equivalents It is necessary to establish relationships between Living Unit Equivalents and the various land uses. The following density relationships have been determined after a review of developed land uses within the city, a comparison of consumption rates of each land use category and comparisons with the American Society of Civil Engineers design recommendations. The service unit to be applied is a typical single family dwelling without regard to the number of bedrooms. Such a unit is otherwise referred to as a "dwelling unit" and for the purpose of this plan the two terms are interchangeable. The following table itemizes the projected densities per land use category. These numbers take into account the loss of acreage to rights -of -ways. /Mitchell &/Morgan, LLP - 13 - Table 7 Projected Densities Per Land Use Category Land Use Category Dwelling Units per Acre Rural Density Residential ( <1/3 d.u. /acre) .25 Low Density Residential (1/3 - 2 d.u. /acre) 1 Medium Density Residential (3 — 6 d.u. /acre) 4 High Density Residential (7 — 9 d.u. /acre) 8 Residential Attached (Multi - family) 13 Commercial /Industrial 10 Parks 0 Schools /Institutional 2 Agricultural 0 Water Service Area "03 -01 " L UE Calculations The existing land use acreages and living unit equivalents for the Water Service Area "03 -01" are shown in Table 8.

Since impact fees are collected at the time of new construction, only new LUE's may be charged directly for new capital improvement projects in the "03 -01" service area. The cost allocation factor removes existing LUE's from the impact fee calculation.

Service distributions allow the City to comply with state law without having to construct a smaller waterline and then return ten to fifteen years later to construct a parallel waterline to accommodate the flow increase. The impact fee reports are updated every three to five years, allowing the service time frame to continually shift forward ensuring eventual recovery of all eligible costs. The service distribution for the first ten year window ('03-'13) was based on the ratio of ultimate LUE's to the LUE's created for the first ten year time frame ('03-'13).

This portion of the utility bills is used toward the repayment those utility bonds. Utility revenue credits ensure that those customers paying impact fees do not fund the capital improvements to service their area through impact fees and their utility bills, thus paying twice for the same improvements. The same would be done for any ad valorem taxes used to fund capital improvements. Currently, the City of College Station does not use ad valorem taxes to finance capital improvements.
