RE: Halligan Water Supply Project Status Update, 2019 Year-in-Review
Bottom Line
Please find attached a regularly scheduled First Quarter 2020 Status Update on the Halligan Water
Supply Project. This report provides a summary of 2019 project accomplishments as well as an
overview of 2020 activities.

HALLIGAN WATER
SUPPLY UPDATE PROJECT
January 2020
BACKGROUND
If approved, the Halligan Water Supply
Project would enlarge Halligan Reservoir,
an existing reservoir on the North Fork
of the Poudre River, to meet the demand
of future Fort Collins Utilities’ water
customers and provide increased reliability
for existing customers in the event of
emergencies, drought and climate-
change uncertainties.
The project would expand the reservoir
by about 8,100 acre-feet by increasing the
height of the existing 70-foot dam by 25
feet. For context, an average single-family
home uses almost a third of an acre-foot of
water each year (about 108,000 gallons).
The project is anticipated to be completed
in 2026.
Permits are required from the U.S. Army
Corps of Engineers (Corps) and other
federal and state agencies to enlarge
Halligan Reservoir. Before issuing permits,
the Corps produces a draft and final
Environmental Impact Statement (EIS)
for public review and comment. The EIS
describes environmental impacts of the
project, along with environmental impacts
of projects identified as alternatives to
enlarging the reservoir.
2019 YEAR IN REVIEW
• Draft EIS Release – This milestone was achieved in November.
• Development of mitigation and enhancement measures – The
Conceptual Mitigation Plan was developed in 2019 – released with
the draft EIS.
• Land acquisition and easements – Staff worked with several
landowners to develop easement agreements – some
are nearing completion.
• Community engagement and communication – Public outreach
was conducted to educate customers, solicit feedback from
stakeholders and prepare for public review/comment of the
draft EIS. The extent of those metrics is below.
• Cost Estimate – Project costs and uncertainties were evaluated and
are shown as a range to reflect the project’s evolving nature
(see reverse).
• Design – A competitive process was used to select an engineering
firm to design the dam expansion.
2020 PLANNED ACTIVITIES
This year, the draft EIS phase will be completed and the design and
state permitting phases of the project will begin.
• Draft EIS review – The Corps will evaluate public comments and
incorporate them in a final EIS, which could take up to two years.
• Preliminary design – Design will begin, including data collection
and development of conceptual details for the enlarged dam.
• Outreach and communications – Periodic outreach will continue.
• State permits – Consultation with Colorado Parks & Wildlife and
Colorado Department of Health and Environment will begin as will
preparation of the Fish and Wildlife Plan.
PROJECT SCHEDULE
The draft EIS was released in 2019. Construction could begin as early as 2024. Other project milestones are shown below.

Figure 2: $ Spent vs. Projected Costs
ANTICIPATED COSTS
Project costs were updated in 2019 pending the
release of the draft EIS and with information
learned over the previous two years. The estimate
is presented as a range due to the long-term
nature of the project, the conceptual nature of
the current design and the uncertainty associated
with a complex water supply project. As noted in
previous quarterly updates, costs are anticipated
to change and likely grow as the scope is refined
and permitting requirements and design are
better understood. However, the “probable cost”
range is intended to capture future cost changes.
Costs will be evaluated in 2021 after preliminary
design is complete and more is known about the
project design and permitting. Costs will continue
to be updated as new information is obtained.
Updated cost estimates and other decision
factors will be evaluated at milestones to verify
that the project remains the most cost-effective
water supply solution for our customers.
Currently, the Halligan Project is anticipated to
provide firm yield at about $15,000 per acre-foot
and is the most cost-effective project to meet
the City’s water supply needs. For comparison,
the market rate for firm yield from the Colorado-
Big Thompson (CBT) Project is approximately
$60,000. Also, the Northern Integrated Supply
Project (NISP) and Windy Gap Firming Project
unit costs are currently $30,000 and $20,000 per
acre-foot, respectively.
