HALLIGAN WATER
SUPPLY UPDATE PROJECT
April 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, state and county 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. The draft EIS was
released in November 2019.
PROGRESS UPDATE
Draft EIS – Approximately 60 comment letters were received. They are
being reviewed by the Corps and Fort Collins Utilities and responses to
comments are being developed.
Land acquisition and easements – Staff worked with several
landowners to develop easement agreements.
Preliminary design – Preliminary design is slated to begin this year.
Onboarding of the design team is ongoing.
State permits – Formal consultation will begin with Colorado Parks and
Wildlife this year for the Fish and Wildlife Mitigation Plan. Preliminary
work also is being conducted to support the Section 401 Colorado
Water Quality Certification.
Community engagement and communication – Public outreach has
been scaled back slightly after the draft EIS release. Outreach continues
to educate customers. Outreach and engagement over the first quarter
of 2020 is shown below:

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 again in 2021 after
preliminary design is complete and more is known
about the project design and permitting and
mitigation requirements. Costs will continue to be
updated as new information is obtained. Updated
cost estimates and other decision factors will
be evaluated regularly 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.
