Scope of Work
A. Data Collection and Water and Wastewater Model Update
Al. Project Kick -Off Meeting: Freese and Nichols, Inc. (FNI) will meet with the City to review
scope, project team and schedule of the project, and present a data request memorandum.
A2. Data Collection: FNI will compile information from the City including GIS files, pump /lift
station layouts, pump curves, storage tank facility layouts, recently completed system
improvements, water production data, utility billing data, and wastewater flow data.
A3. Roadway Data Collection: FNI will assemble available roadway inventory, pertinent roadway
construction cost data and traffic count data available from the City. To support this study
update, traffic count data will be collected at up to 15 (fifteen) locations throughout the city. This
task effort will be facilitated through the use of a sub - consultant. A review of existing traffic
count data will be made to determine optimal traffic count locations. Following completion of
the data collection effort, data will be compiled into a data base for use in subsequent analysis.
A4. Update Water & Wastewater System Models: FNI will update the water model in H2OMAP
Water software using the updated GIS. FNI will update the wastewater model in H2OMAP Sewer
software using the updated GIS. The models consist of all -inch and larger lines that are
currently in the GIS plus recently constructed lines that may no appear in the GIS.

B. Land Use Assumptions and Water & Wastewater Load Projections
/ r
B1 . Develop Land Use Assumptions: FNI will utilize NCTCOG population and employment
projections, as well as City forecasts and large planned developments to develop 10 -year and
Buildout land use assumptions.
B2. Review Historical Water Demands and Wastewater Flows: FNI will obtain and evaluate
historical water usage and wastewater flow data to review trends and calculate peaking factors.
This data will be used to update expected per- capita loads for future projections.
B3. Develop and Distribute Water Demand Projections: FNI will develop water demand projections
for 10 -year and Buildout conditions using the future land use assumptions and selected design
criteria. FNI will distribute water demands throughout the service area based on the existing and
future population and employment distribution.
B4. Develop and Distribute Wastewater Flow Projections: FNI will develop wastewater flow
projections for 10 -year and Buildout conditions using the future land use assumptions and
selected design criteria. Flows will be calculated by sub - basin. FNI will distribute wastewater
flows throughout the service area based on the existing and future population and employment
distribution.
B5. Progress Meeting — Land Use Assumptions and Projections: FNI will meet with the City to
discuss population, land use assumptions, and load projections. FNI will address comments from
City staff and make revisions as necessary.
C. Water and Wastewater System Hydraulic Analysis and Impact Fee CIP Update
C 1. Evaluate Pumping and Storage Capacity: FNI will evaluate existing and future pumping capacity
with regards to TCEQ requirements and general industry recommendations. Ground and elevated
storage will also be evaluated.
C2. Conduct Water and Wastewater System Modeling: FNI will conduct hydraulic modeling for
existing, 10 -year, and Buildout conditions. Water system modeling will consist of average day,
maximum day, peak hour, and fire flow demand conditions. Wastewater system modeling will
consist of peak wet weather flow conditions.
C3. Identify Water System Improvements: FNI will utilize modeling results to identify water system
improvements required to support growth for the 10 -year, and Buildout conditions.
C4. Identify Wastewater System Improvements: FNI will utilize modeling results to identify
wastewater system improvements required to support growth for the 10 -year, and Buildout
conditions.
C5. Develop Capital Improvements Plan (CIP): FNI will develop prioritization and costs for each
proposed project in Year 2011 dollars including engineering and contingencies. Large scale
citywide maps will be produced showing proposed projects, costs, and recommended in- service
dates.
C6. Progress Meeting —Water and Wastewater CIP: FNI will meet with the City to discuss the results
of the water and wastewater system modeling and CIP development.
D. Water and Wastewater Impact Fee Analysis
D1. Identify Existing Projects Eligible for Impact Fee Cost Recovery: FNI will review recently
completed water and wastewater improvements over the last 5 years and determine which
projects are eligible for future cost recovery from growth.
D2. Conduct Water and Wastewater Impact Fee Capacity Analysis for Existing Projects: FNI will
utilize water and wastewater models to analyze recently completed projects for remaining
capacity for impact fee cost recovery for 10 -year projected growth.
D3. Develop Water and Wastewater Impact Fee CIP: FNI will develop an impact fee CIP based on the
improvements recommended as part of the Master Plan. Impact fee eligible improvements are
intended to serve growth within the next 10 years. Maps will be prepared showing the proposed
water and wastewater capital improvement plan projects included in the impact fee calculation.
D4. Conduct Water and Wastewater Impact Fee Capacity Analysis for Proposed Projects: FNI will
utilize water and wastewater models to analyze proposed water and wastewater improvements for
eligible capacity for impact fee cost recovery for 10 -year projected growth.
D5. Calculate Project Costs Eligible for Impact Fee Cost Recovery: FNI will utilize the capacity
analysis and capital project costs to calculate percentage of project cost eligible for impact fee
cost recovery.
D6. Develop Service Unit Equivalents (SUEs) for Water and Wastewater Systems: FNI will utilize
equivalent capacity of water meters to establish the service unit equivalents (SUEs) required in
Chapter 395 of the Local Government Code for both existing and 10 -year growth conditions.
D7. Calculate Maximum Allowable Water and Wastewater Impact Fees: FNI will develop maximum
allowable water and wastewater impact fees using the 50% credit method based on the existing
and proposed capital improvement costs to support 10 -year growth based on projected increase in
SUEs.
Phase E. Roadway Impact Fee Analysis
El. Existing Capital Improvement Inventory Update: FNI will prepare an inventory and analysis of
existing roadways in the City. The inventory will contain the following information of existing
collector and arterial status roadways by area:
• Roadway segment name and limits
• Length (in miles), number of lanes and facility type (divided, undivided, collector, arterial,
etc)
• PM peak hour directional volumes
An existing condition analysis will be prepared to calculate capacity provided and utilized of
existing capital improvements.
E2. Determination of Projected Roadway Demand: FNI will determine the projected roadway
demand (vehicle -miles of travel, VMT) over the 10 -year planning period based on socio-
demographic data developed in the land use assumptions report prepared as part of the update
process. The SUE table will serve as the basis for determination of the number of service areas
over the 10 -year planning period.
E3. Prepare Roadway Capital Improvements Program: FNI will prepare an updated impact fee capital
improvement program (CIP) with growth considerations over the 10 -year plan period, the City
Thoroughfare Plan, fiscal constraints, and City Staff input. Cost information of existing and
proposed CIP projects will be developed. Previously completed projects will be incorporated.
The City will provide completed project cost data. An evaluation of existing CIP projects will
also be performed to ensure excess capacity is available for the projects to be included in the
impact fee analysis.
E4. Roadway CIP Database Update and Maximum Fee Calculation: FNI will compile CIP data into
an updated roadways project database and update the maximum cost per service unit for service
areas within the city. The database will include:
• Roadway segment names and limits.
• Number of lanes, length, and facility type
• Project cost information (construction, engineering, ROW, debt service)
• Capacity provided by CIP projects, utilized and percent attributable to new growth
• Project cost attributable to new growth
The cost per service unit will be calculated based on the necessitated cost of the impact fee capital
improvements program and VMT growth over the ten -year plan period. Per legislative mandate,
the impact fee CIP will be credited by 50% prior to the cost per service unit calculation.
E5. Update of Land Use Equivalency Table: The land use equivalency table will be updated based on
updated trip generation and trip length data available from the Institute of Transportation
Engineers (8 Edition Trip Generation) and NCTCOG (Workplace Survey), respectively. City
Staff input will also be sought for input on specific land uses to add or revise.
Phase F: Impact Fee Report Development and Meeting Attendance
Fl. Develop Draft Impact Fee Report and Meet with City: FNI will prepare a Draft Water,
Wastewater and Roadway Impact Fee Report showing land use assumptions, water and
wastewater impact fee eligible capital improvement costs, roadway impact fee eligible capital
improvement costs, and maximum allowable water, wastewater and roadway impact fees. Three
copies of the draft report will be delivered to City. FNI will meet (1 meeting) with the City to
discuss the draft report.
F2. Meet with City Staff: FNI will meet (1 meeting) with City Staff to discuss the report findings,
impact fee calculations, and recommendations for setting the water, wastewater, and roadway
impact fees for the City.
F3. Present Capital Improvements Plan and Impact Fee Analysis Results to Citizen Advisory
Committee: Following review by City Staff, FNI will present results of the water and wastewater
impact fee analysis and recommendations to Citizen Advisory Committee (1 meeting). FNI will
prepare exhibits for the Citizen Advisory Committee Presentation on Impact Fees.
F4. Finalize Impact Fee Report: Based on City comments, FNI will prepare a final Water,
Wastewater, and Roadway Impact Fee Report and deliver 10 copies to the City.
F5. Attend City Council Public Hearing: Attend one (1) Public Hearing to present and address
questions about the land use assumptions, capital improvements plan, and impact fee calculations.
