CHAPTER 13 – Capital Improvement Program
The Drinking Water Utility uses the Capital Improvement Program (CIP) to plan strategically for investments in capital projects over a 20-year planning horizon. As part of the budgeting process each year, City Council adopts a Capital Facilities Plan, appropriating funds for projects to be implemented during a 6-year planning horizon.
A capital project is a structure, improvement, piece of equipment, land or other major asset that has a useful life of at least five years and a project cost that exceeds $50,000.
The Capital Improvement Program helps meet the Drinking Water Utility’s Goal 6:
Infrastructure is prudently financed, and sustainably constructed, maintained and operated to ensure reliable delivery of high quality water to a growing community.
This CIP incorporates projects described in:
• Chapter 4 – Source of Supply
• Chapter 6 – Reclaimed Water Program
• Chapter 7 – Groundwater Protection Program
• Chapter 8 – Source Infrastructure
• Chapter 9 – Storage Infrastructure
• Chapter 10 – Transmission and Distribution Infrastructure
• Chapter 11 – Water Quality Program
• Chapter 12 – Operation and Maintenance Program
This chapter describes the methodology used in developing the CIP, and presents the costs and schedules for projects planned for implementation in 2015-2034. Other projects are described for which schedules are primarily dependent on the timing of future development.
13.1 Development of CIP
To develop the CIP, Utility staff first identified projects that address water system needs or deficiencies. These projects were then prioritized via a formal evaluation process. Generally, projects of higher priority were scheduled for implementation within the six-year planning horizon. Cost estimates for these projects were then developed and escalated to the anticipated year of implementation. Each of these steps is described below.
Project Prioritization
The Utility developed a protocol to systematically compare and prioritize the wide range of potential capital projects. The protocol provides a consistent basis for characterizing the benefits from capital projects, comparing projects and documenting the reasons why certain projects are selected for funding. The Utility then used this protocol in a workshop attended by staff responsible for various Utility functions in order to refine the list of projects to be included in the CIP.
The prioritization process considered eight criteria, intended to address the primary benefits provided by typical Utility capital projects. Each criterion has an associated scoring system used to calculate a project priority score. In addition to the raw scores, each of these criteria was weighted. This allowed some criteria to more strongly influence how projects were selected and prioritized.
The eight criteria and the weights selected during the priority-setting workshop are shown in Table 13.1.

The results of the prioritizing process were then reviewed by Utility management, along with an assessment of other information including potential impacts on the Utility’s finances, to finalize the schedule of capital projects included in the 2015-2034 CIP.
Cost-Estimating Methodology
Total project-level cost estimates have been developed for each capital project included in the 2015-2034 CIP. Many cost estimates were generated during development of the 2009 water system plan, and have been escalated to 2014 values, according to the Engineering News Record (ENR) cost indexes. For newly developed project cost estimates, each cost includes the following components:
• Base construction cost. Includes all labor and material costs needed to construct a project.
• Sales tax. Calculated as 8.8 percent (the 2014 local tax rate) of the base construction cost.
• Construction contingency. Takes into account the uncertainties associated with estimating project costs at this planning level. Calculated as 25 percent of the total of base construction plus sales tax.
• Design engineering. Includes City and consultant design costs, and other related costs, such as permitting and construction administration. For most projects, this is calculated as 25 percent of the base construction cost. However, for projects with more complex design or permitting needs, a higher percentage of the base construction cost is used.
These elements are summed to determine the total project-level cost estimate for a project, expressed in September 2014 dollars. Where applicable, design and construction costs are depicted spanning multiple years, to reflect the phasing typically used for larger projects.
13.2 2015-2034 Planned Projects
The Utility has identified capital projects planned for implementation between 2015 and 2034. In addition, potential projects with schedules driven primarily by development-related activities have been identified.
Table 13.2 presents the schedule of CIP projects planned for implementation between 2015 and 2034. Descriptions of each project are organized by project type. Developer-contributed projects are not included in this table, as they will not require City funding; they are described in the narrative project list.
Some projects received prior appropriations from City Council through adopted Capital Facilities Plans, while other projects reflect future needed appropriations. The City’s future Capital Facilities Plans will reflect the new appropriations needed to implement the CIP shown in Table 13.2. Map 13.1 depicts approximate project locations.
The largest projects included in the first ten years of the CIP (i.e., 2015-2024) are:
• Construction of the new Log Cabin Storage Tank and the associated transmission main extension in the Morse-Merryman Road area.
• Corrosion control treatment facilities at the new McAllister Wellfield.
• Seismic retrofits of the Fir Street Storage Tanks.
• Construction of new Fones Road Booster Pump Station and rehabilitation of nearby water main.
In addition to these and other capital projects, the CIP includes significant investment in ongoing rehabilitation and replacement of system assets such as small diameter water mains, and aging and asbestos cement piping.
