5. Unfinished and New Business
a. ARC Strategic Goals Discussion
Chair Norling presented proposed strategic priorities for the ARC. She wants the ARC
priorities to coincide with the City Council’s strategic goals which had been adopted
earlier in the year. Her goals for the Commission were:
• Democracy of ideas
• Amplify Human Imagination
• Aggregate Collective Wisdom
• Give everyone a chance to opt in.
She said that the unwritten mission is to ensure that Mendota Heights has its fair share
of air noise. After discussion, it was decided by consensus that the more accurate
mission would be to “Ensure that Mendota Heights receives an equal, or no more than
its fair share of air noise.”
The MASAC was discussed, and why that concept had failed in the early to mid-1990’s.
Chair Norling also reviewed the ARC’s powers and duties as outlined in the City Code.
Chair Norling asked that the ARC has a larger discussion. Byrnes said that the presence
of former City Councilor Liz Petschel meant that the ARC probably didn’t need to
Page 1
provide the City Council with regular updates, but that with Ms. Petschel’s retirement,
that should be given consideration.
Chair Norling reviewed the City’s Mission and Vision statements, and the five Strategic
two year priorities. She asked that the ARC think about what a future state scenario
might be. She proposed that ARC have a special meeting in June, where each
commissioner would come back with an idea to brainstorm a future scenario for ARC.
Sloan asked for clarification as to what could be done, and how much flexibility ARC can
have. In response, McNeill reviewed the City’s five priorities, and said that the closest
thing for the ARC to pursue would be the enhancement of City services. He said that
with the loss of former Councilor Petschel, there is an even greater need to educate and
interact with the community on airport noise issues. Jacobson spoke about the need to
let residents know that they can be heard when they have a complaint, rather than it
being lost to data when they report it to MSP. She suggested that maybe ARC members
could respond when complaints are brought to city hall, rather than a NOC staff
member.
Dunn said, as an example, C-130’s were a question, and that at one time they didn’t
qualify for being listed in the top 10 noise complaint generators, they are now. Hamiel
said that, in his experience, when people have someone to listen to a complaint and
then have a connection with someone who is able to respond to questions, he found
that people are generally satisfied.
It was stated that the ARC could be a sounding board for the community. Jacobson said
that MAC now has a community engagement office.
b. Establish ARC Work Session Meeting Date
It was decided that a special meeting could be held at 6 pm on Thursday, June 3. The
July meeting would be a joint meeting with the Eagan ARC.
6. Acknowledge Receipt of Reports and Correspondence
a. Review of Airport Operation Statistics
i. Complaint Information— It was noted that, since Sally Lorberbaum is no longer
on the Commission, she will not be doing complaints. Sloan said that there
should be a discussion about who is going to do what in terms of responsibilities
for preparation of the reports.
ii. Runway Use Information-- Neuharth said that the charts looked to be fine, and
that they are back within the control lines again.
iii. Turboprop Information—Neuharth said that he had just received the turboprop
information, and will go through it prior to the next meeting.
Page 2
iv. Noise Monitor Information—Dunn commented that by comparison, Minneapolis
is noisier than Mendota Heights, but that it has five to seven times the number
of flights.
b. MAC Monthly Reports—March 2021
There were no comments
7. NOC Meeting
Jacobson reported that there had been a “light” agenda at the NOC meeting which had
been held earlier in that day. The Committee had receive an update on Converging
Runway Operations at MSP. Jacobson said that Rebecca McPherson of the FAA had said
that there is no FAA legal requirement to do community engagement and it is not the
norm for this instance. However, the FAA has committed to doing more outreach and it
will be virtual.
She said that the airlines gave updates, and each reported that things were slowly
returning to normal; Delta is no longer blocking middle seats. Brad Juffer had talked
about engagement, and said that the May listening session was small in numbers of
attendees.
8. MAC Monthly Reports
There were no comments.
9. Adjourn
Chair Norling asked for a motion to adjourn. Motion by Dunn, second by Sloan.
Motion carried 7-0. The meeting adjourned at 7:01 PM.

AIRPORT RELATIONS COMMISSION WORK SESSION MINUTES
JUNE 3, 2021
A work session meeting of the Mendota Heights Airport Relations Commission was held on
Thursday, June 3, 2021 in the City Council Chambers of Mendota Heights City Hall.
1. Call to Order/Roll Call
Chair Gina Norling called the meeting to order at 5:59 pm. The following commissioners were
present: Gina Norling, David Sloan, William Dunn, Kevin Byrnes, Arvind Sharma, Jim
Neuharth, and Jeff Hamiel.
2. Strategic Planning Session
Chair Norling said that the purpose of the work session was to share the Commissioner’s future
state scenario, and brainstorm how the ARC should operate according to the City Code. She
invited ideas from the Commissioners and discussion followed.
Norling said that she would like to charter an initiative to mitigate the City’s air noise exposure,
and mitigate air noise where possible. She thought that it could be done by neighborhoods.
Byrnes said that we should take advantage of people moving into or remodeling in the 65 dB DNL
area. Realtors could be educated, and that the city could be doing more on prevention. Dunn
agreed, but felt that the education should come through the City Council. He felt that the City
could educate new residents.
Hamiel said that over the years MAC had insulated 17,000 homes at a cost of $500 million. He
said that he would be worried about scaring people away who were considering a move to
Mendota Heights. He was concerned about Mendota Heights getting a bad reputation for airport
noise. He did agree that there are better window options, even for those homes outside of the
65 DNL contour.
Sloan stated that he hadn’t checked airport noise prior to moving into the Copperfield
neighborhood in 1989, but that noise was a problem. He said they had organized their own
neighborhood ARC, which then became a city-wide ARC. In his current Lemay neighborhood,
the construction and insultation is better. He said that his HOA might be able to talk more about
noise as a welcoming committee topic.
Neuharth said that we need to give a history whenever we educate; the noise has improved over
the years. One area to improve communications is regarding military planes, so that people know
that the City can’t control those. Sharma agreed that military planes are a major source of noise.
He suggested having the National Guard speak at a community celebration. McNeill suggested
social media as a communications tool regarding military planes, as well as turbo props and
remodeling information.
Page 4
Sharma said Westchester, NY, has an option for residents to be called back after registering a
complaint. He said that maybe the ARC could do that for Mendota Heights callers. That way,
people would feel like they have been heard.
Hamiel noted concern about the impact of projected growth in airport usage, and what impact
that growth would have on vehicular traffic patterns in neighboring communities. The forecasts
show growth to 48 million airport users in 2030, and 54 million in 2035. He was concerned about
TH 62 becoming a freeway due to increased airport usage.
Norling then asked about next steps. Discussed were ideas such as keeping track of data; creating
near term goals; enhancing city services; looking at the ARC Rules of Order; maintaining and
improving City assets (including intangibles like websites and processes); encouraging and
supporting parks; and conserving Natural Resources.
Norling said that she would map what had been discussed at this session, and would send it out
for comments.
Norling said that she wanted to make certain that Mendota Heights receives no more than its fair
share of airport noise. Sloan said that ARC is more advisory than the other two city commissions,
and that complaints are an important part with which it has to deal. Neuharth cautioned against
creating unrealistic expectations. Byrnes said that we can’t change the planes, but maybe we
can change people complaints and expectations.
3. Adjournment
Chair Norling adjourned the work session meeting at 7:25 pm.

2021 work session. She and those present reviewed the strategies, action items, and action
timing (whether 2021, 2022, or “parked”). Where possible, the participants also determined to
whom the strategy should be assigned, estimated budgetary needs, and desired outcomes. Chair
Norling noted that there were only two meetings remaining in 2021.

the previous June work session, but that all items were on the table.
The commission discussed educational opportunities, including representing ARC at the
upcoming community “coffee and conversation” event to be held on August 14. Hamiel and Dunn
volunteered to represent ARC at that time. Whether to have a table at the Fire Department’s
October Open House could be decided at the September meeting.
It was asked that the City’s Communication Coordinator be invited to attend the September ARC
meeting to talk about the Friday News, and other communications tools.
Chair Norling said that she would update her notes, and get them to city staff for the final draft.

AIRPORT RELATIONS COMMISSION JOINT MEETING MINUTES
CITIES OF MENDOTA HEIGHTS AND EAGAN
EAGAN CITY HALL
JULY 13, 2021
A joint meeting of the Airports Relations Commissions of the Cities of Mendota Heights and
Eagan was held on Tuesday, July 13, 2021, in Eagan City Hall.
1. Call to Order/Roll Call
Chair Michael Johnson of the Eagan ARC called the meeting to order at 6:32 pm. Eagan ARC
members in attendance included: Michael Johnson, Jeff Spartz, William Raker, and Louis
Lundberg. The following Mendota Heights commissioners were present: Chair Gina
Norling, David Sloan, William Dunn, Kevin Byrnes, Arvind Sharma, and Jeff Hamiel.
Eagan staff present: Assistant City Administrator Dianne Miller
Mendota Heights staff present: City Administrator Mark McNeill
MAC staff present: Dana Nelson, Brad Juffers, Brian Ryks
2. Introductions
The individuals present introduced themselves.
3. Presentation—State of the Airport
MAC Executive Director Brian Ryks discussed the current state of the MSP airport and the
impacts of COVID on airport operations. He said that they had made efforts to retain
employees as much as possible, and so had lost only about 50 of the original compliment of
650 pre-COVID employees. He reported that the Airport had received $158 million in CARES
Federal assistance, and another $118 million in American Rescue Plan funds. Passenger
flights have picked up since Memorial Day, and were currently at 72% of 2019 numbers.
Parking was at 60% of pre-pandemic totals, and international flights were at 40%.
He discussed CDC issues and cleanliness. Ryks also stated that one of the biggest challenges
was obtaining enough employees—there were currently 400 openings for concession
workers alone.
5. Updates on Current Efforts
Eagan Chair Johnson reported that they were keeping an eye on Runway 17, now that flight
volumes were increasing. He said that Eagan had been approached on the Consent Decree,
along with Minneapolis and Richfield. That was being considered for an extension, rather
than a sunsetting. He also said that they were looking at their strategic goals, and that
those would be reported to their City Council.
Chair Norling of Mendota Heights said that the Mendota Heights ARC was working to align
its strategic goals with the City’s strategic planning goals. She suggested that the Chairs
and Vice-Chairs of each ARC should meet jointly at the end of this year so that an agenda for
Page 7
the next joint meeting could be set. Chair Johnson agreed that that might avoid possible
duplication of efforts.
6. Other Business
There was no other business presented.
7. Adjourn
Chair Johnson adjourned the meeting at 7:25 PM.
