Jessica L. Brown, P.E., Freese and Nichols, Inc. SUBJECT: Draft Water System Analysis Report of Animate Habitat, Ltd. and Pebble Creek Developments DATE: August 11, 2004 This memorandum report presents the results of a study of water distribution system improvements needed for the existing Pebble Creek development and the proposed Animate Habitat, Ltd. development. Pebble Creek is approximately 1300 acres, and Animate Habitat, Ltd. is approximately 1100 acres. Pebble Creek is expected to build out within seven years, and Animate Habitat, Ltd. is expected to buildout within fifteen to eighteen years. Freese and Nichols, Inc. (FNI) projected populations and water demands for the buildout of both developments with input from the City and used the City's InfoWater model to determine improvements needed to meet the buildout water demands. 1. EXISTING WATER SYSTEM This area is currently supplied from the southwest by a 24 "/18" line from the Greens Prairie Tank Elevated Tank. System improvements currently under design which were considered completed for this study were the 18" Barron Road water line, a portion of the 24" line along FM 2154, and the 18" water line along Rock Prairie Road. The 24" line in FM 2154 will be extended in the future along the future State Highway 40. The Rock Prairie water line will provide an 18" loop and improve supply to the area from the northwest once it is completed. These ongoing system improvements are shown as red dashed lines on Figure 1. 2. POPULATIONS & WATER DEMANDS The City provided FNI with the proposed land use plans for both developments, existing platted lots for the Pebble Creek development, proposed plats for the Pebble Creek development, proposed land use densities, phasing plans of both developments, and development standards from the B /CS Unified Design Guidelines Manual. The proposed land uses are shown on Figure 1; however, recent and proposed revisions in isolated areas are not reflected on the map.

The assumptions used for developing the projected populations and water demands are summarized in Table 1. For the Pebble Creek development, the proposed number of units for a majority of the development has previously been determined; therefore, the actual number of units was used for projecting population. In areas where the number of units was unknown, the number of units was calculated based on the proposed land use densities.

A higher per capita water use was used than the Development Guidelines because historical water usage for existing residences in Pebble Creek showed to be higher than 100 gpcd. Peaking factors and people per acre were obtained from the Development Guidelines.

Approximately 13.76 commercial acres are developed, and approximately 51.9 industrial acres are developed. The population was estimated based on the total number of existing residential lots that were developed as of July 2004. Animate Habitat, Ltd. is expected to begin development in late 2004 or early 2005. The resulting average day demand is 0.53 MGD. The maximum day demand is 1.19 MGD, and the peak hour demand is 2.12 MGD. 2.2 Projected 2011 (Interim) Population & Water Demands The interim phase analyzed was for the buildout of the Pebble Creek development and partial development of the Animate Habitat, Ltd. development. The Animate Habitat, Ltd. development is expected to develop from west to east. The projected 2011 populations and water demands are shown in Table 3. The residential population for Pebble Creek was developed from a blend of land use by acreage and the number of units currently built. The projected residential populations for Animate Habitat, Ltd. are a product of the number of acres, the units /per acre and residential people per unit for each land use category. The buildout residential population for Pebble Creek is 5,541, and the projected 2011 residential population for Animate Habitat, Ltd. is 5,351. The total residential population for both developments is 10,892. The resulting average day demand is 2.27 MGD. The maximum day demand is 6.11 MGD, and the peak hour demand is 9.08 MGD. 2.3 Projected Buildout Population & Water Demands The second phase analyzed was for the buildout of both developments. The projected buildout populations and water demands are shown in Table 4. The buildout residential population for Animate Habitat, Ltd. is 14,126. The total buildout residential population for both developments is 19,667. The resulting average day demand is 3.73 MGD. The maximum day demand is 8.40 MGD, and the peak hour demand is 14.92 MGD. 3. WATER SYSTEM ANALYSIS The water distribution system was analyzed for the two phases: interim and buildout. The proposed development average day, maximum day and peak hour demands were added to the current water system model for each phase. The recently constructed improvements and near term improvements were also added to the model. Because of the lower elevations in the developments, pressures were not a controlling factor in determining future improvements. Additional transmission capacity will be needed to supply both interim and buildout water demands and projected fire flows. The model results are summarized in Tables 5, 6 and 7 for existing, 2011 and buildout demand conditions. The proposed system improvements are shown on Figure 2 by phase.

These improvements are shown as red dashed lines on Figure 2. The following improvements are recommended to serve 2011 demands: • A 12" line along Hwy. 6 from Greens Prairie Road to the existing 12" line to support future retail development in Pebble Creek. • A 16" water line loop along Rock Prairie Road from Greens Prairie Road and along the south property line of Pebble Creek to an extension of the existing 12" line in Pebble Creek Parkway. It is anticipated that this line will be extended further east on Rock Prairie Road for future development outside the scope of this study. • A 12" water line extension along a future road in the far east portion of Pebble Creek. • An extension of the 12" line along Pebble Creek Parkway as a 12" water line to the south property line of Pebble Creek and as a 16" to the future major thoroughfare in Animate Habitat, Ltd. • A proposed 16" line south along Pebble Creek Parkway and west along a future thoroughfare to the 18" line in the Animate Habitat, Ltd. development. • An extension of the existing 18" water line in Lakeway Drive to the proposed 16" line in Animate Habitat, Ltd. • A 12" line connecting the existing 8" line along Hwy. 6 and the proposed 16" loop in the Animate Habitat, Ltd. development. 3.2 Buildout Improvements The improvements to support buildout water demands in both developments include both on -site and off -site system improvements. These improvements are shown as dashed green lines on Figure 2. Additional off -site improvements will also be needed to improve the operation of the Greens Prairie Tank. The improvements needed for buildout demands include: • A 12" loop along future major thoroughfares in the Animate Habitat, Ltd. development that will supply the eastern portion of the development. (on -site) • A 24" line along FM 2154 from the existing 30" at Rock Prairie Road to the existing 12" in Graham Road and along future SH 40 from FM 2154 to the existing 24" line.

RECOMMENDATIONS The proposed phasing and sizing of water system improvements are shown on Figure 2. The proposed 18" line along Lakeway Drive and the proposed 16" line along Rock Prairie Road were also sized to allow for future water system expansion to the south and east. At least one off -site system improvement, the 24" line in FM 2154 and future SH 40, will be needed to serve buildout demands. Additional off -site system improvements will be needed to improve the operation of the Greens Prairie Elevated Tank and provide additional transmission capacity to this area. It is recommended that additional off -site improvements be evaluated as a part of the Water Master Plan to ensure that the improvements will be adequately sized for future development in the existing City limits and future service area in the ETJ.

Draft Water System Analysis Report of Animate Habitat, Ltd. and Pebble Creek Developments August 11, 2004 Page 2 of 8 FNI developed populations and water demand projections for the following four demand conditions: • Average Day Demands, • Maximum Day Demands, • Peak Hour Demands and • Maximum Day Demands under Fire Flow Conditions. The assumptions used for developing the projected populations and water demands are summarized in Table 1. For the Pebble Creek development, the proposed number of units for a majority of the development has previously been determined; therefore, the actual number of units was used for projecting population. In areas where the number of units was unknown, the number of units was calculated based on the proposed land use densities.

A higher per capita water use was used than the Development Guidelines because historical water usage for existing residences in Pebble Creek showed to be higher than 100 gpcd. Peaking factors and people per acre were obtained from the Development Guidelines.

The maximum day demand is 1.19 MGD, and the peak hour demand is 2.12 MGD. 2.2 Projected 2011 (Interim) Population & Water Demands The interim phase analyzed was for the buildout of the Pebble Creek development and partial development of the Animate Habitat, Ltd. development. The Animate Habitat, Ltd. development is expected to develop from west to east. The projected 2011 populations and water demands are shown in Table 3. The residential population for Pebble Creek was developed from a blend of land use by acreage and the number of units currently built. The projected residential populations for Animate Habitat, Ltd. are a product of the number of acres, the units /per acre and residential people per unit for each land use category. The buildout residential population for Pebble Creek is 5,541, and the projected 2011 residential population for Animate Habitat, Ltd. is 5,351. The total residential population for both developments is 10,892. The resulting average day demand is 2.27 MGD. The maximum day demand is 6.11 MGD, and the peak hour demand is 9.08 MGD. 2.3 Projected Buildout Population & Water Demands The second phase analyzed was for the buildout of both developments. The projected buildout populations and water demands are shown in Table 4. The buildout residential population for Animate Habitat, Ltd. is 14,126. The total buildout residential population for both developments is 19,667. The resulting average day demand is 3.73 MGD. The maximum day demand is 8.40 MGD, and the peak hour demand is 14.92 MGD. 3. WATER SYSTEM ANALYSIS The water distribution system was analyzed for the two phases: interim and buildout. The proposed development average day, maximum day and peak hour demands were added to the current water system model for each phase. The recently constructed improvements and near term improvements were also added to the model. Because of the lower elevations in the developments, pressures were not a controlling factor in determining future improvements. Additional transmission capacity will be needed to supply both interim and buildout water demands and projected fire flows. The model results are summarized in Tables 5, 6 and 7 for existing, 2011 and buildout demand conditions. The proposed system improvements are shown on Figure 2 by phase.

These improvements are shown as red dashed lines on Figure 2. The following improvements are recommended to serve 2011 demands: • A 12" line along Hwy. 6 from Greens Prairie Road to the existing 12" line to support future retail development in Pebble Creek. • A 16" water line loop along Rock Prairie Road from Greens Prairie Road and along the south property line of Pebble Creek to an extension of the existing 12" line in Pebble Creek Parkway. It is anticipated that this line will be extended further east on Rock Prairie Road for future development outside the scope of this study. • A 12" water line extension along a future road in the far east portion of Pebble Creek. • An extension of the 12" line along Pebble Creek Parkway as a 12" water line to the south property line of Pebble Creek and as a 16" to the future major thoroughfare in Animate Habitat, Ltd. • A proposed 16" line south along Pebble Creek Parkway and west along a future thoroughfare to the 18" line in the Animate Habitat, Ltd. development. • An extension of the existing 18" water line in Lakeway Drive to the proposed 16" line in Animate Habitat, Ltd. • A 12" line connecting the existing 8" line along Hwy. 6 and the proposed 16" loop in the Animate Habitat, Ltd. development. 3.2 Buildout Improvements The improvements to support buildout water demands in both developments include both on -site and off -site system improvements. These improvements are shown as dashed green lines on Figure 2. Additional off -site improvements will also be needed to improve the operation of the Greens Prairie Tank. The improvements needed for buildout demands include: • A 12" loop along future major thoroughfares in the Animate Habitat, Ltd. development that will supply the eastern portion of the development. (on -site) • A 24" line along FM 2154 from the existing 30" at Rock Prairie Road to the existing 12" in Graham Road and along future SH 40 from FM 2154 to the existing 24" line.

RECOMMENDATIONS The proposed phasing and sizing of water system improvements are shown on Figure 2. The proposed 18" line along Lakeway Drive and the proposed 16" line along Rock Prairie Road were also sized to allow for future water system expansion to the south and east. At least one off -site system improvement, the 24" line in FM 2154 and future SH 40, will be needed to serve buildout demands. Additional off -site system improvements will be needed to improve the operation of the Greens Prairie Elevated Tank and provide additional transmission capacity to this area. It is recommended that additional off -site improvements be evaluated as a part of the Water Master Plan to ensure that the improvements will be adequately sized for future development in the existing City limits and future service area in the ETJ.
