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:

Goal

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.

•    OM-14    McAllister Mitigation - Woodland Creek (ongoing)

Description: Funds the City’s share of the operations and maintenance of a new facility jointly owned with the City of Lacey as part of the McAllister Water Rights Mitigation Plan. The Woodland Creek Groundwater Recharge Facility infiltrates reclaimed water into the shallow groundwater aquifer in the Woodland Creek area, partly offsetting impacts of groundwater withdrawals at the McAllister Wellfield. (See also Chapter 6.)

Justification/Need: Supports continued operation of the McAllister Wellfield and is required as part of the mitigation plan.

Reclaimed Water Projects

The following reclaimed water-related capital projects address deficiencies or needs described in Chapter 6.

•    RW-1    Reclaimed Water Infrastructure (anticipated 2021, estimated $250,000)

Description: Continue development of an infrastructure network to convey reclaimed water to customers or support regional reclaimed water system expansion efforts.

Justification/Need: Supports efficient use of the City’s limited potable water resources.

•    RW-2    Port of Olympia – Eliminate Northern Dead End (anticipated 2017, estimated $50,000)

Description: Installation of additional reclaimed water piping in the existing portion of the system that provides reclaimed water to the Port, so as to provide looping and eliminate dead ends.

Justification/Need: Reduces water quality concerns in dead-end piping, and supports efficient use of the City’s potable water resources.

•    RW-3    Reclaimed Water Filling Stations (anticipated 2021, estimated $100,000)

Description: Installation of water filling stations that provide reclaimed water for construction-related purposes.

Justification/Need: Increases the use of reclaimed water, which reduces the need to use potable water for non-potable needs.

Planning Projects

•    PL-1    Water System Plan (anticipated 2021, estimated $300,000)

Description: Updates to the Water System Plan, which are required every six years by the Washington State Department of Health.

Justification/Need: This is a regulatory requirement, and also ensures the Utility is planning sufficiently to meet future needs and is investing wisely in its infrastructure.

•    PL-2    Infrastructure Pre-Design and Planning (ongoing)

Description: Perform pre-design evaluation and analysis of water system project alternatives.

Justification/Need: Evaluates project needs and costs of CIP projects prior to appropriation in the annual Capital Facilities Plan, in order to refine information provided in the CIP.

Development-Related Projects

The following projects will be implemented as part of private development projects. Scheduling of these improvements will depend on the timing of development activity. Development-related projects are not included in Table 13.2, since no City funds are required.

•    DEV-1    Kaiser Road Pump Station and Storage Tank. This pump station and storage tank will be constructed as part of a development project planned for the area south of Highway 101 on Kaiser Road. While these facilities will primarily serve future development, they will also address deficiencies in the distribution system’s ability to provide adequate pressures during peak hour demand conditions to a small area of Zone 298, as described in Chapter 10.

•    DEV-2    Kaiser Road South (12-inch). Installation of 4,900 lineal feet of 12-inch water main, extending from the existing 12-inch main on Kaiser Road near 7th Avenue, south to a point west of Park Drive.

•    DEV-3    Kaiser Road South (8-inch). Installation of 1,000 lineal feet of 8-inch water main, extending from the future Kaiser Road Storage Tank to Park Avenue.

•    DEV-4    Cooper Point Road North. Installation of 3,000 lineal feet of 12-inch water main, extending north in Cooper Point Road.

•    DEV-5    Log Cabin Road Extension. Installation of 4,350 lineal feet of 16-inch water main, extending from the existing 12-inch main at the south end of Van Epps Drive, east to the existing 12-inch main on Wiggins Road by 7th Avenue.

•    DEV-6    South Bay Water Main Extension. Installation of 10,650 lineal feet of 12-inch water main.

•    DEV-7    26th Avenue Water Main Extension. Installation of 2,900 lineal feet of 12-inch water main, extending from the existing 12-inch main on 26th Avenue by Huber Lane, east on 26th to a proposed 12-inch main in South Bay.
