(“Halligan Project”).

HALLIGAN WATER
SUPPLY UPDATE PROJECT
Fourth Quarter 2017
BACKGROUND
The Halligan Water Supply Project will
enlarge Halligan Reservoir, an existing
reservoir on the North Fork of the Poudre
River, to help meet future water supply
needs. The population for Fort Collins
Utilities’ Service Area is projected to
increase by 45,000 by 2065, and the
current water supply is not enough to
support that growth under City policy,
especially during a drought.
The project would expand the reservoir by
about 8,100 acre-feet (AF) by increasing
the height of the existing dam by 25 feet.
For context, an average single-family home
served by Utilities uses almost a third of an
AF of water each year.
In order to enlarge Halligan Reservoir, the
City requires permits from the U.S. Army
Corps of Engineers (Corps) and other federal
and state agencies. Before issuing permits,
the Corps will produce an Environmental
Impact Statement (EIS), which will be
published for public review and comment.
The EIS will describe the environmental
impacts of the project, along with impacts of
other alternatives to enlarging Halligan.

PROGRESS UPDATE
City staff, consultants and the Corps made significant progress during the
fourth quarter of 2017. Developments include:
• Submitted a “Showing Document” to the Corps that provides
supplemental information and the City’s position on project benefits,
such as flow improvements and wetland formation, not currently
addressed in the draft EIS. At a length of nearly 1,200 pages, this is a
substantial City work product.
• Met with Corps Omaha District leadership. Another meeting with
Omaha Corps staff is anticipated in late-February to discuss Corps
feedback on the Showing Document.
• Continued writing the draft EIS, which is approximately 80 percent
complete. Most EIS work has been on hold pending review of the
Showing Document.
• The Corps anticipates releasing the draft EIS later this year. The
draft EIS has been delayed so that new information from the Showing
Document can be incorporated.
• Met with Colorado Parks and Wildlife and local landowners to
discuss plans for future public recreation at Halligan Reservoir.
• Provided outreach on the project to the Governor’s office, the City’s
congressional delegation and environmental organizations.
• Refined minimization, mitigation and enhancement measures for
the Halligan enlargement. The City will release a conceptual mitigation
plan concurrently with the draft EIS.

PERMITTING SCHEDULE
As previously mentioned and reported to City Council, incorporating the Showing Document into the EIS will delay the
federal permitting process. A revised schedule for other project milestones will be provided in the forthcoming cost update.

Throughout 2017, staff prepared
a comprehensive cost update for
the Halligan Project to address
uncertainties in the federal permitting
process, changes in the timeline and
refinements to project requirements.
The update is the most thorough
evaluation of project costs to date and
includes an independent contractor
estimate of construction costs.
Updates were discussed with
the Water Board at a Feb. 1,
2018, Work Session. Water Board
suggested certain modifications to the
methodology used in the cost update
and adjustments to the timeline,
which staff are currently addressing.
Staff intends to provide Council a
memo detailing the comprehensive
cost update in March. That memo
will provide a detailed account of past
and future expenses.
Project expenditures in the fourth
quarter of 2017 totaled $200,000.
