EXECUTIVE SUMMARY 1.0

Background

In November 2016, the City of Buda, Texas, authorized Freese and Nichols, Inc. (FNI) to perform an impact fee analysis on the City’s water and wastewater systems. The purpose of this report is to summarize the methodology used in the development and calculation of water and wastewater impact fees for the City of Buda. The methodology used herein satisfies the requirements of the Texas Local Government Code Section 395 for the establishment and update of water and wastewater impact fees.

2.0

Land Use Assumptions

Population and land use are important elements in the analysis of water and wastewater systems. Water demands and wastewater flows depend on the population served by the systems and determine the sizing and location of system infrastructure. A thorough analysis of population, along with land use, provides the basis for projecting future water demands and wastewater flows. Growth projections by planning area for the water service area were provided to FNI by the City, and were developed as part of the current water system model update project. These growth projections were augmented through discussions with City staff to develop growth projections by planning area for the portion of the wastewater service area that falls outside of the water service area. Growth in connections by planning area were developed for 2017, 2022, 2027, and Buildout. Table ES-1 presents the growth projections for the City of Buda water and wastewater service area.

Capital Improvements Plan

An impact fee capital improvements plan (CIP) was developed for the City of Buda based on the land use assumptions. The recommended improvements will provide the required capacity to meet projected water demands and wastewater flows through year 2027. Tables ES-2 and ES-3 display the water demand and wastewater load projections in terms of million gallons per day (mgd) for the City of Buda. These projections were the basis for determining the location and magnitude of the CIP projects. Table ES-2

Impact Fee Analysis

The previous impact fee ordinance was adopted in October of 2010. This ordinance set the water impact fee for a single-family meter at $2,187 and the wastewater impact fee for a single-family meter at $2,531 for a combined maximum impact fee of $4,718. This project is an update to the 2010 ordinance. For existing or proposed projects, the impact fee is calculated as a percentage of the project cost, based upon the percentage of the project’s capacity required to serve development projected to occur between 2017 and 2027. The total projected cost includes the projected capital improvement cost to serve 10-year development, the projected finance cost for the capital improvements, and the consultant cost for preparing and updating the CIP. A 3.85% interest rate was used to calculate

1.0 BACKGROUND Chapter 395 of the Texas Local Government Code requires an impact fee analysis before impact fees can be created and assessed. Chapter 395 defines an impact fee as “a charge or assessment imposed by a political subdivision against new development in order to generate revenue for funding or recouping the costs of capital improvements or facility expansions necessitated by and attributable to the new development.” In September 2001, Senate Bill 243 amended Chapter 395 thus creating the current procedure for implementing impact fees. Chapter 395 identifies the following items as impact fee eligible costs: •

Construction contract price



Surveying and engineering fees



Land acquisition costs



Fees paid to the consultant preparing or updating the capital improvements plan (CIP)



Projected interest charges and other finance costs for projects identified in the CIP

Chapter 395 also identifies items that impact fees cannot be used to pay for, such as: •

Construction, acquisition, or expansion of public facilities or assets other than those identified on the capital improvements plan



Repair, operation, or maintenance of existing or new capital improvements



Upgrading, updating, expanding, or replacing existing capital improvements to serve existing development in order to meet stricter safety, efficiency, environmental, or regulatory standards



Upgrading, updating, expanding, or replacing existing capital improvements to provide better service to existing development



Administrative and operating costs of the political subdivision



Principal payments and interest or other finance charges on bonds or other indebtedness, except as allowed above

2.0 LAND USE ASSUMPTIONS Population and land use are important elements in the analysis of water and wastewater systems. Water demands and wastewater flows depend on the population served by the systems and determines the sizing and location of system infrastructure. A thorough analysis of population and land use provides the basis for projecting future water demands and wastewater flows.

2.1

Service Areas

The service areas for City of Buda’s water and wastewater systems differ slightly in terms of extent. The water service area contains much of the area within the City Limits to the north, and even extends past the extra-territorial jurisdiction (ETJ) in some areas. The southern portion of the area within the City Limits is served by another utility. The wastewater service area includes the entire water service area, with the addition of parts of the Coves of Cimmaron neighborhood in the north, as well as a majority of the southern portion of the City Limits not included in the water service area. Figures 2-1 and 2-2 illustrate the water and wastewater service areas, respectively.

Growth Projections

The City provided FNI with projected growth in connections by planning area that were developed as part of ongoing water distribution system modeling performed by another consultant. The planning area boundaries were developed as part of the separate study, but generally follow neighborhood boundaries. To account for growth in parts of the wastewater service area that are not included in the water service area, the growth projections were evaluated in discussions with City staff, who had knowledge of where and when future development is most likely to occur. Growth in connections by planning area were developed for 2017, 2022, 2027, and Buildout. Table 2-1 presents the growth projections for the City of Buda water and wastewater service areas. Figure 2-3 and Figure 2-4 show the growth projections by planning area for water and wastewater, respectively. A table summarizing the growth in water and wastewater connections by planning area is provided in Appendix A. Table 2-1

Water & Wastewater Impact Fee Report City of Buda

3.0 WATER AND WASTEWATER CAPITAL IMPROVEMENTS PLAN The impact fee CIP developed for the City of Buda is based on the land use assumptions presented in the previous section. The CIPs were developed using hydraulic models of both the water and wastewater systems. The recommended improvements will provide the required capacity to meet projected water demands and wastewater flows through year 2027.

3.1

Existing Water and Wastewater Systems

The existing water distribution system consists of a network of lines ranging in size from 2 inches to 24 inches in diameter, four pump stations (PS), four ground storage tanks (GST), and five elevated storage tanks (EST). The City has five groundwater wells that deliver water into the GSTs at the PSs. The City also has treated surface water supply from the Guadalupe-Blanco River Authority (GBRA) at the Bonita Vista PS. The City operates three pressure zones (PZ): High, Middle, and Low. The hydraulic grade lines (HGL) High and Low PZs are controlled by ESTs, and the Middle PZ is supplied through pressure reducing valves (PRV) from the High PZ, which set the HGL in the Middle PZ. A map of the existing water distribution system is shown on Figure 3-1. The existing wastewater system has 14 lift stations, a network of lines ranging from 4 inches to 24 inches in diameter, and a 1.5 MGD wastewater treatment plant (WWTP). The wastewater collection system serves a slightly larger area than the water distribution system, and collects flow from users that are currently served water by other utilities. Figure 3-2 displays a map of the existing wastewater collection system.

Water & Wastewater Impact Fee Report City of Buda 3.2

Water Model Update and Validation

The City provided the most up-to-date versions water distribution system model. The water system model was built in Bentley’s WaterGEMS® software. K. Friese and Associates (KFA) updated the water model, adding recently constructed water lines and facilities. A 72-hour extended period simulation (EPS) analysis was performed by KFA with 2017 and 2027 projected maximum day demands. EPS modeling provides a means to evaluate the system over time to assess response to hourly changes in demand, pump cycling, and tanks filling or draining. KFA utilized the hydraulic model to develop a 10year water CIP as part of a separate study. As part of the impact fee update study, the existing system demand allocation was updated using geocoded billing data. In order to verify that the hydraulic model accurate represented the actual distribution system, a model validation was performed. Field testing was conducted March 17th to 27th, 2017. Eight pressure recorders were installed throughout the distribution system. The pressure testing data was used to validate the EPS model scenario by verifying that modeled pressures were generally within five psi of the measured field pressures. Graphs of the pressure recorder data and a map showing the validation results and pressure recorder locations are provided in Appendix B. The model was used to conduct fire flow analysis under maximum day demands, and determine minimum observed pressures during maximum hour demands for both 2017 and 2027.

3.3

Wastewater Model Update

The City provided the existing wastewater system hydraulic model developed by Lockheed, Andrews & Newnam, Inc. (LAN) as part of the 2012 Wastewater Master Plan. The wastewater collection system model was built in Bentley’s SewerGEMS® software.

FNI updated the model to include newly

constructed lines and facilities, and updated the existing system flow allocation using geocoded billing data. This model was used to evaluate the capacity of the existing system during peak wet weather conditions for 2017, 2027, and Buildout.

3.4

Water Demand and Wastewater Load Projections

The land use data and historical water demands, and wastewater flow characteristics were used to develop future water demands and wastewater flows based on a projected average day and maximum day demand per connection and peaking factors. Design average day and maximum day demand per connection values were chosen to align with projected demands used by KFA to create the proposed 10-

3-4

Water & Wastewater Impact Fee Report City of Buda year water CIP. As no peak hour water demand data were available, a peak hour to maximum day demand peaking factor of 1.75 was selected to be conservative based on previous experience with cities of similar size. For wastewater, no historical connection or peak wet weather flow data were available. Therefore, the average dry weather flow of 245 gallons per connection was used to be consistent with the 2012 Wastewater Master Plan performed by LAN. A wet weather peaking factor of 4.0 was chosen based on recommendations from the Texas Commission on Environmental Quality (TCEQ). These projections were allocated into the respective hydraulic models, which served as a basis for determining the location and magnitude of the CIP projects. Table 3-1 and 3-2 show historical water demands and wastewater flows in millions of gallons per day (mgd), respectively. The design criteria for projected water demand and wastewater flow calculations are shown in Table 3-3. Table 3-4 presents the projected water demands in mgd, and Table 3-5 presents the projected wastewater flows in mgd for the City of Buda. Table 3-1

TCEQ Requirements

As a retail water purveyor, the City of Buda must comply with the rules and regulations for public water utility systems set forth by TCEQ in 30 TAC Chapter 290, Public Drinking Water. The City is required to meet the TCEQ elevated storage capacity requirement of 100 gallons per connection and total storage capacity requirement of 200 gallons per connection. In addition to storage requirements, the City is also required to meet the TCEQ pumping capacity requirements. The City currently provides at least 200 gallons per connection of elevated storage resulting in a TCEQ pumping requirement of 0.6 gallons per minute (gpm) per connection. If the City provided less than 200 gallons per connection of elevated storage in the future, the TCEQ pumping requirements would increase. The City reported having 4,380 active connections as of July 2017. TCEQ capacity requirements were evaluated by PZ. Existing and future storage and pumping capacities were evaluated and are summarized in Table 3-6 through Table 3-9. The City is currently meeting all requirements except for distribution pumping capacity in the combined Middle and High PZs. However, this deficiency is addressed in the proposed CIP with the addition of the Alliance Regional Water Authority (ARWA), formerly known as the Hays County Public Utility Agency (HCPUA) Phase 1 PS, which will serve the Middle and High PZs. This PS is scheduled to come on line in 2018. Table 3-6 TCEQ Requirement 200 gallons per connection

Water and Wastewater System Analyses 3.6.1

Storage and Pumping Recommendations

This section summarizes the evaluation of the storage and pumping capacity for the City based on study criteria developed by FNI. These criteria are generally more stringent than the TCEQ requirements and take into consideration system-specific factors including operational flexibility, fire suppression, redundancy, and energy efficiency. The design criterion used to analyze EST capacity is the volume required to provide adequate equalization storage for peak hour demands plus emergency storage for fire protection. It is typically assumed that half of the EST capacity is used to meet peak hourly demands in excess of the maximum day rate (equalization volume), while the other half of the tank is used for fire

3-10

Water & Wastewater Impact Fee Report City of Buda protection and emergency conditions (fire/emergency volume). This evaluation assumes that pumping will meet 125% of maximum day demands and elevated storage will meet 40% of peak hour demands. Table 3-10 shows the recommended elevated storage by PZ in terms of millions of gallons (MG). The combined Middle and High PZ available elevated storage is below what is recommended. However, the storage volume of the proposed ARWA Phase 1 EST included in the CIP was sized such that the City will be able to meet these recommendations, even through Buildout. Table 3-10

The recommended firm pumping capacity was calculated based on meeting 125% of maximum day demands. Firm pumping capacity is defined as the total available pumping capacity with the largest pump in the PZ out of service. Table 3-11 presents the recommended firm pumping capacity. The Low PZ has adequate pumping capacity to meet demands through 2027. The available pumping capacity in the Middle and High PZs is less than recommended, even in 2017. However, as mentioned in Section

Recommended ground storage capacity was calculated based on providing storage equivalent to 4 to 8 hours of maximum day demand. Storage volumes equivalent to 4, 6, and 8 hours of maximum day demand were calculated, and range from least conservative to most conservative, respectively. Table 3-12 presents the recommended ground storage capacity by PZ. The available ground storage in the Low PZ is adequate to provide 4 hours of maximum day demand through 2027, while the available ground storage in the Middle and High PZs is below all recommended volumes. However, the GST proposed as part of the ARWA Phase 1 PS will provide additional ground storage in the Middle and High PZs. It should also be noted that the Low PZ and the combined Middle and High PZs have 1.60 MG and 0.85 MG of elevated storage, respectively, a portion of which can serve as additional supply in emergency situations.

Water System Hydraulic Modeling

As mentioned in Section 3.2, the majority of the modeling that went in to developing the 10-year water CIP was done by KFA. However, the hydraulic model of the water distribution system was utilized to measure minimum pressures in the system during periods of peak demand. During the maximum day EPS analysis, the peak hour demand condition was simulated by setting the highest hourly peaking factor in the diurnal demand pattern equal to the maximum day to peak hour peaking factor. Peak hour demand represents the single hour of the year with the highest system demand. Peak hour simulations are used to assess the ability of the distribution system to maintain residual pressures because the highest demand period typically induces the lowest pressure due to increased headloss throughout the system. Appendix C contains maps showing the minimum pressure observed in the model under both existing and 2027 peak hour demand conditions. The TCEQ minimum required pressure within a distribution system is 35 pounds per square inch (psi) under all demand conditions. As seen in Appendix C, most of the system is currently meeting that minimum requirement, and all parts of the system exhibit minimum pressures above 35 psi during 2027 modeling. To evaluate the fire suppression capabilities of the water distribution system, a fire flow analysis was conducted under existing maximum day demand conditions, and with the proposed 10-year improvements in place. TCEQ requires a minimum residual pressure of 20 psi be maintained while delivering the fire flow demand. For this analysis, a steady-state model run was utilized to calculate the available fire flow at each node in the system with a pressure of 20 psi. Appendix C shows the results of

3-13

Water & Wastewater Impact Fee Report City of Buda the fire flow simulations for both the 2017 and 2027 systems. The majority of the water system can provide at least 1,000 gpm, which is a typical residential fire flow demand. Most available fire flows below 1,000 gpm are due to small diameter lines in isolated areas. Upsizing of smaller lines and looping are two methods to improve low fire flow. Available fire flow for commercial, multi-family, and industrial land uses should be evaluated on a case-by-case basis.

3.6.3

Wastewater System Hydraulic Modeling

The wastewater model along with selected design criteria were used to evaluate the wastewater collection system. Gravity lines were recommended for replacement when the ratio of actual flow depth to the diameter of the pipe (d/D) in modeled conditions was 0.85 or greater. Slopes for new lines are based on the minimum slope requirement for the given pipe diameter set forth by the TCEQ. Proposed lines are sized for replacement of the existing line. The design criteria for lift station pumping is to provide firm pumping capacity to meet 125% of the peak wet weather design flows. TCEQ requires that the lift station be capable of pumping the expected peak flow; however, it is recommended to design for 125% of the peak wet weather design flow. The firm pumping capacity is defined by the TCEQ as the total available lift station pumping capacity with the largest pump out of service.

3.7

Water and Wastewater System Improvements

Proposed water and wastewater system improvement projects were developed based on water demand and wastewater flow projections. A summary of the costs for each of the projects required for the 10year growth period used in the impact fee analysis for both the water and wastewater systems is shown in Table 3-13 and Table 3-14, respectively. Costs listed for the existing projects are based on actual design and construction cost data provided by the City. Detailed cost estimates for the proposed water and wastewater system projects are included in Appendix D and Appendix E, respectively. The costs are in 2017 dollars and include an allowance for engineering, surveying, and contingencies. Cost estimates do not include allowances for right-of-way acquisition. Table 3-13 and Table 3-14 show a 2017 percent utilization as the portion of a project’s capacity required to serve existing development. This portion of the project cost is not impact-fee-eligible. The 2027 percent utilization is the portion of the project’s capacity that will be required to serve the City in 2027. The 2017-2027 percent utilization is the portion of the project’s capacity required to serve development from 2017 to 2027. The portion of a project’s

3-14

Water & Wastewater Impact Fee Report City of Buda total cost that is used to serve development projected to occur from 2017 through 2027 is calculated as the total actual cost multiplied by the 2017-2027 percent utilization. Only this portion of the cost is used in the impact fee analysis. The proposed 10-year water system projects are shown on Figure 3-3. Proposed wastewater projects are shown on Figure 3-4.

Water & Wastewater Impact Fee Report City of Buda

4.0 IMPACT FEE ANALYSIS The current impact fee ordinance was adopted in October of 2010. This ordinance set the water impact fee for a single-family meter at $2,187 and the wastewater impact fee for a single-family meter at $2,531 for a combined maximum impact fee of $4,718. This project is an update to the 2010 ordinance. The impact fee analysis involves determining the utilization of existing and proposed projects required as defined by the capital improvement plan to serve new development over the next 10-year period. For existing or proposed projects, the impact fee is calculated as a percentage of the total project cost, based upon the percentage of the project’s capacity required to serve development projected to occur between 2017 and 2027. Capacity serving existing development and development projected for more than 10 years in the future cannot be charged to impact fees.

4.1

Service Units

According to Chapter 395 of the Texas Local Government Code, the maximum impact fee may not exceed the amount determined by dividing the cost of capital improvements required by the total number of service units attributed to new development during the impact fee eligibility period. A water service unit is defined as the service equivalent to a water only connection or a water/wastewater connection for a single-family residence. A wastewater service unit is defined as the service unit equivalent to a water/wastewater connection for a single-family residence. The service associated with public, commercial, and industrial connections is converted into service units based upon the capacity of the meter used to provide service. The number of service units required to represent each meter size is based on the safe maximum operating capacity of the appropriate meter type. American Water Works Association (AWWA) standards C700 (Cold Water Meters – Displacement Type, Bronze Main Case) and C702 (Cold Water Meters – Compound Type) were used to determine the safe maximum operating capacity, as these meter types represent those in place and stocked by the City. The service unit equivalent for each meter size used by the City is listed in Table 4-1.

Service Unit Equivalent 1.0 1.6 2.0 6.4 12.8 20.0 56.0 96.0 152.0 200.0

Safe maximum operating capacity is based on AWWA standards C700 and C702.

Typically, in Buda, single-family residences are served with 3/4-inch water meters. Larger meters represent public, commercial, and industrial water use. Other water purveyors in areas which the City serves wastewater but not water do use water meters as small as 5/8-inch. Even though these meters are smaller than the smallest meter the City currently allows, it is the opinion of City staff that 5/8-inch water meters should be treated the same as 3/4-inch meters. Therefore, they were assigned a service unit equivalency of 1.0. The City provided data that included the meter size of each active water meter in their water service area as of May 2017. Monarch Utilities and South Buda WCID #1 also provided meter sizes for all water meters that fall within the City of Buda wastewater service area. Although the service unit equivalencies are shown for 10-inch and 12-inch meters in Table 4-1, no developments requiring meters of that size are projected in the next ten years. Tables 4-2 and 4-3 show the water and wastewater service units for 2017 and the projected service units for 2027.

Maximum Impact Fee Calculations

Texas Government Code Chapter 395 outlines the procedures and requirements for calculating maximum allowable impact fees to recover costs associated with capital improvement projects needed due to growth over a 10-year period. Chapter 395 also requires a plan that addresses possible duplication of payments for capital improvements. This plan can either provide a credit for the portion of revenues generated by new development that is used for the payment of eligible improvements, including payment of debt, or reduce the total eligible project costs by 50 percent. The City of Buda has selected to utilize the reduction of the total eligible project costs by 50 percent to determine the maximum allowable impact fees.

4-3

Water & Wastewater Impact Fee Report City of Buda Chapter 395 of the Texas Local Government Code states that the maximum impact fee may not exceed the amount determined by dividing the cost of capital improvements required by the total number of service units attributed to new development during the impact fee eligibility period less the credit to account for water and wastewater revenues used to finance capital improvement plans. The total projected costs include the projected capital improvement costs to serve 10-year development, the projected finance cost for the capital improvements, and the consultant cost for preparing and updating the Capital Improvements Plan. A 3.85% interest rate was used to calculate financing costs.

Tables 4-4 and 4-5 display a summary of the maximum allowable impact fee

calculations for water and wastewater, respectively. A comparison graph showing impact fees in other nearby cities is presented on Figure 4-1. Table 4-4
