City Council Memorandum
To: Mayor Fasbender & City Councilmembers
From: Chris Jenkins, Parks & Recreation Director
Date: May 15, 2022
Item: Hastings Civic Arena West Rink Roof and Refrigeration
Council Action Requested:
Review potential scenarios, and provide support and authorization for staff
to move forward with a preferred option.
Background Information:
1. The roof system on the west rink is now 25 years old, has served its
useful life, is failing and we see an increase in water leaks inside the
west rink year after year. With the assumption that the Hastings Civic
Arena will remain where it is and serve the Hastings community and
region for the next 30+ years, it is time to invest in a new roofing
system.
Installation of a modified built up roofing system on the west rink is
the preferred and most beneficial outcome. This type of system
allows the roofing insulation to meet current building codes, allows for
proper drainage to be achieved, collected and routed to the west side
of the building and diverted away from the main entrance of the
building. It also allows the potential to install a solar energy system
on top of the roof to help reduce energy costs at the facility.
2. The current refrigeration system is an R-22 system. That refrigerant
is no longer in production, is difficult to acquire, and is far less efficient
than newer refrigerants like ammonia. Replacement of this
refrigeration system has been a discussion topic for multiple years,
and during that time frame the cost of updating has continued to
increase significantly.
To replace this system in 2024 requires the City to make some
decisions now. There are components that have 12-month lead
times, and there are design and engineering tasks that also must be
completed in advance to ensure the components are sized correctly
and will operate within the overall system.

Ultimately Council needs to decide on a path to move forward with both of
these projects. There is potential to have the west rink roof replaced yet in
2023, however that window of opportunity is closing fast.
Staff recommendation is:
• Plan for and commit to a 2024 comprehensive project as it was
proposed to the State Bonding Committee to include the refrigeration
system, west rinks roof, lobby roof, varsity locker room roof, LowE
ceiling in the west rink, interior lighting upgrades to LED, and solar
system installation at a cost estimated around $5 million.
• This would require an estimated $441,217.00 immediate
investment in both the Motor Control Center for the
refrigeration system, and refrigeration design work to
appropriately size the MCC’s.
• Staff to seek affordable, temporary roof repairs to minimize
leaks.
• A completed 2024 project would be funded through a
combination of funding sources to include Arena fund balance.
Other sources COULD include State Bonding, and would also
require issuing debt.
Alternate, less desirable options include:
• Pull the trigger on the west rink roof in 2023 as a standalone project
only at an estimated cost of $960,667.00.
• As mentioned, there is the potential to replace the west rink
roof in 2023 utilizing the Design Build process, however a
decision needs to be made now to have that option.
• A 2023 project would be funded with both Arena and Parks
fund balance. This scenario would reduce the ability to use
Parks fund balance for other projects in 2024 and beyond.
• This option still leaves the need to update the refrigeration
system, and if that is to occur in 2024, the $441,217.00
investment in the MCC and Design still needs to be made.
• Plan for and commit to a 2024 West Rink Roof replacement project
only, with today’s estimated cost of $960,667.00.
• Delaying this to 2024 will certainly increase the cost, to what
degree is unknown.
• A 2024 project would be funded with both Arena and Parks
fund balance. This scenario would reduce the ability to use
Parks fund balance for other projects in 2024 and beyond.
• This option still leaves the need to update the refrigeration
system, and if that is to occur in 2024, the $441,217.00
investment in the MCC and Design still needs to be made.
These are large and important projects to protect the city’s assets, improve
energy efficiency, and ensure this facility is able to serve the community for
X-B-01
Financial Impact:
With any scenario there will be significant financial investment, and a need
to rely on multiple sources of funding. Staff, with Council support, will
continue to seek State Bonding funds for this project.
On the positive side of the financial coin, there is potential to sell the
recovered R-22 refrigerant currently used in our system. The revenue
generated will depend upon the market rate at the time of recovery and any
fees needing to be paid to recover that volume of refrigerant.
Advisory Commission Discussion:
N/A
Council Committee Discussion:
These projects have been discussed over the years at a variety of levels
within council committee’s and council workshops. Council provided support
for staff to apply for State Bonding in 2022 and again in 2023. Most recently,
these projects were discussed at the April 3, 2023 City Council workshop,
along with other potential projects. It was understood that these projects are
necessary to preserve the asset that is the Hastings Civic Arena.

years to come. Staff are seeking Council support to move ahead with
staff recommendation or guidance on which direction to move forward
with.
