Once again, Impact Fee Advisory Board needs to make recommendations on the Capital Improvement
Plan for the upcoming budgeted expenditure of Impact Fee money for the following:
Street Impact Fee Fund
Fire Impact Fee Fund
Water Impact Fee Fund
Wastewater Impact Fee Fund
In updating the schedules, we have the opportunity to remove items that have been completed or are
no longer needed, adjust project costs estimates, and add projects that are needed. We drop the
current fiscal year (FY19) from the plan and extend the plan by a year, to encompass FY24.
Water Impact Fee Fund– Attached is a staff‐recommended Water Impact Fee CIP Section, which shows
the summary and details of the plan. We will be looking to discuss these items with the Committee so
that we can complete the draft Capital Improvement Plans and bring them back for Committee
approval. Once approved by the Committee, we will deliver them to the City Commission. We have
tentatively scheduled:

WATER IMPACT FEE FUND DETAIL BACKGROUND This enterprise fund revenue source is impact fees. Revenue estimates for Water Impact Fees have been updated with the 5‐year average collection amount, detailed on the following page. We have included a slight adjustment for potential financial effects of the fee study underway and reduced our growth rate slightly. Revenues have grown on average by 13% per year, over the past 5 years. For the CIP, we have used the 5‐year Average collection, plus 2% growth each year from FY20 to FY24. $1,833,000.00 $1,663,000.00 $2,262,000.00 $1,885,123.00 $2,757,565.00 2,080,137.60 $‐ $500,000.00 $1,000,000.00 $1,500,000.00 $2,000,000.00 $2,500,000.00 $3,000,000.002014 2015 2016 2017 2018 Average FY14‐18Water Impact Fee Revenues
CAPITAL PLAN SUMMARY The scheduled projects include projects identified in the Integrated Water Resources Plan (IWRP). WIF40 SOURDOUGH TRANSMISSION MAIN – PHASE 2 – This project provides significant additional water supply capacity. This construction, beginning in phase 1 already underway, will assist in overcoming vulnerabilities presented by the aging and unknown condition of the existing transmission main between the City’s Water Treatment Plant and Sourdough Tank. The phase 1 was and phase 2 is also being proposed as 90% Impact Fees and 10% Water Utility. WIF32 Groundwater Well Field and Transmission Construction ‐ Water right permitting and mitigation plan; purchase of mitigation water rights; construction of aquifer recharge or other mitigation infrastructure; acquisition of land for well field site; construction of wells, power, power backup, instrumentation and controls, SCADA, control building and site improvements; and transmission main construction to tie GW supply into the existing system. Beginning in FY21 for an estimated total of $8 million. This is critical for meeting long‐range water supply needs and enhancing overall water supply resiliency and redundancy. It enhances connectivity by providing a redundant water supply source in the event of Sourdough WTP outage. A significant amount of borrowing has been incurred for Projects WIF32, and WIF 40. Over $12 million will need to be borrowed to complete these three projects. Because of the uncertainty of the revenue stream, the Water Utility will need to borrow via revenue bonds and be reimbursed by the Water Impact Fee Fund. There may be rate‐requirements to support this borrowing. We will know more after the upcoming Water Rate Study.

Unscheduled Project NameUnscheduled Project Description AmountProject #West Transmission Main ‐ Phase 1 ConstructionThe project consists of a constructing a new transmission main from the Sourdough water treatment plant to the southwestern edge of the existing distribution network (S.19th and Graf St.) to serve future anticipated growth and provide water delivery redundancy. This second transmission line from the WTP to the City's distribution system is critical to provide a second path to get potable water from the WTP into the City, as well as to adequately serve the rapidly growing western portions of the City with potable water and fire flows. Potable water delivery and fire flows will be improved in the southwest, west and northwest portions of the City. This transmission line connects to the existing distribution system at a location that enables the existing Sourdough and Hill top tanks to be filled even if the Sourdough pipeline is out of service. This project mitigates the risk of not having enough potable water to serve the City's residents or provide fire suppression. 28,006,293 WIF055126 West Sourdough Reservoir 1The project consists of a constructing a new gravity fed ground storage reservoir to the south/southwest of the City, which would tie into the West Water Transmission Main – Phase 1 and serve the existing City water distribution system. This reservoir supplies water to the City’s existing distribution network, to provide necessary storage capacity for the entire system, as well as contributes to adequate water supply capacity for future development along the City's western half. In the near term the storage provided by this reservoir will augment storage provided by the City's existing Sourdough and Hilltop Tanks. In the long‐term it provides storage for the west and northwest areas of the City. This project mitigates the risk of not having enough potable water and fire flow in the southwest area of the City. This project is directly tied to construction of the West Water Transmission Main ‐ Phase 1. 9,757,500 WIF27UNSCHEDULED
Unscheduled Project NameUnscheduled Project Description AmountProject #East Transmission MainThe project consists of a constructing a new transmission main that would ensure adequate water supply capacity for future developments located both east and northeast of the existing distribution system (extending approximately from East Kagy Blvd to Kelly Canyon Rd and Story Hill Rd). Without this transmission main, potable water and fire flows will eventually become insufficient in the east and northeast portions of the City. This main also supplies the future East Mountain Zone, which has a substantial demand. This project better connects the east and northeast portions of the City with the supply from the City's WTP. In conjunction with the west transmission mains, it will provide a more looped supply for the majority of the City. What safety or risk measures are mitigated with this project: This project mitigates the risk of having inadequate potable water and fire flows to the City's east and northeast areas. This project leverages improvements in delivery of water due to the Sourdough Main replacement or paralleling. It will also enable siting of storage in the City's east and northeast areas. 7,167,372 WIF30West Transmission Main Planning StudyPlanning study to identify key design parameters for WTM, right of way, route alignment, and timing for bringing WTM online. Eventual construction of the West Transmission Main is necessary to provide redundancy for the Sourdough Transmission Main as well as adequate potable water and fire flow for the City's west, northwest and north areas, and it provides capacity sufficient for UBO and delivery of 34 MGD from future WTP expansion. Conveyance of water to the City's western, northwestern and northern areas will be more efficient that moving water through downtown and existing PRVs. 400,000 WIF36Sourdough Canyon Natural Storage ConstructionConstruction of natural water storage infrastructure alternatives planned and designed in project WFP_53 that augment water supply availability, reduce susceptibility to drought impacts, and maximize existing water rights. This project provides enhanced water supply availability to support future growth and development, and reduces drought susceptibility and peak runoff impacts. Leveraging potential exists with federal/state grants, federal/state cooperative agreements (consistent with fed initiatives to increase drought resiliency in western states and consistent with recommendations in state water plan to increase storage in closed basins). Project implements recommendations of the IWRP to develop storage in Sourdough. 8,000,000 WIF38
Unscheduled Project NameUnscheduled Project Description AmountProject #West Transmission Main ‐ Phase 1 DesignDesign of the first phase of the West Transmission Main, the criteria for which would be developed in the West Transmission Main Planning Study (WIF36). This project will reduce the consequence of a failure on the Sourdough Transmission Main, by providing a second pipeline to convey water to the City from the WTP, and water delivery to the City's western side will become more efficient. The Sourdough Transmission Main is currently a single point of failure for conveyance of water from the Sourdough WTP. Other affected projects include subsequent phases of West Transmission Main design and construction, and construction of storage reservoirs on the City's west side. 2,907,235 WIF41West Transmission Main ‐ Phases 2‐5 Design & ConstructionThe project consists of remaining phases (2 thru 5) of the west Transmission Main, completing the transmission loop around the city's western flank. Extending the West Transmission Line further north into the City's future western and northwestern developments to ensure adequate potable water and fire flow for west and northwest Bozeman residents. The northwest portion of the City remains the least well connected area to the distribution system. Flow to the northwest must come through the existing PRVs from the Sourdough and Hilltop Tanks, or from the northeast Lyman source. This main will bring water from the WTP well into the northwest portion of the City. Therefore, this project mitigates the risk of not having enough potable water or fire flow to serve the City's west residents. This project will also provide the ability for the City to connect additional storage reservoirs on the City's southwest and west to satisfy maximum day demand and fire flows. 61,669,396 WIF424975 Southwest Reservoir 1The project consists of a constructing a new ground storage reservoirsouthwest of town, which would tie into the West Transmission Main – Phase 2 and serve the City’s future western and northern water distribution system. 9,757,500 WIF48Total Water Impact Fee Unscheduled127,665,296
