1.Agenda Review:
No changes were made to the Agenda.
2.Review and Approve Minutes of 9 November 2020:
Mr. Barritt moved to approve the Minutes of 9 November 2020 as written. Mr. Kaufman
seconded. Motion passed unanimously.
3.City and School District Budget Presentation:
a.City FY22 Budget:
Mr. Hubbard said the major considerations in preparing the FY22 budget were:
a.Sensitivity to the tax rate in light of COVID
b.Maintaining the current level of service (which for the first time has not been
possible)
c.Meet all contract obligations
d.Supporting the Capital Improvement Plan (CIP)
e.Funding the annual assessment and other entities
Of the $50,700,000 total city budget, $26,745,677 is from the General Fund. Projected revenue
is $9,300,000, leaving $17,400,000 to be raised by taxes.
The total increase in expenses from FY21 is $145,923. The decrease in revenue is anticipated at
$261,960. This leaves an increase in the tax rate of 0.98.
STEERING COMMITTEE
20 JANUARY 2021
PAGE 2
The major items in the CIP include:
a.Paving (the hope had been to fund this at $1,000,000, but it was cut to
$700,000
b.Tree care (emerald ash bore removal was projected at $100,000 and was cut
to $50,000
c.Fleet cuts for both the Fire and Police Departments
d.Police equipment and computerization
e.Parks improvements (some of which will be funded by impact fees)
f.Fire/Rescue (an ambulance replacement was deferred)
The total CIP funding is $400,000 below what was approved for FY21. Some things are on hold
to determine receipts from local option taxes, and some projects have been moved to future
years.
There have also been some staff positions that will not be funding in FY22. These include one
Police officer, one Firefighter, City Planner, Deputy Finance Officer, parks laborer, HR assistant.
Four other positions were merged into two positions.
Expense factors in the proposed budget include projects in the CIP, health insurance (up 5%),
agreements with collective bargaining, Workers Compensation and other insurances, increase in
funding to open the new Library (equipment and staffing), and an anticipated decrease in local
option tax revenue of $250,000. These factors total $1,300,000.
Special assessments, including the Winooski Valley Park Department, Regional Planning
Commission, County Court, Green Mountain Transit, Vermont League of Cities & Towns, Front
Porch Forum and CCTV total $836,000.
Revenue factors include:
a.An estimated 1% growth in the Grand List
b.Increase in ambulance fees
c.Recording fees/vital records
d.Fire and electrical inspections
e.Rentals at 19 Gregory Drive (thanks to the Miller family which turned the
entire building over to the city 10 years earlier than planned, there are now 2
tenants providing rental income)
STEERING COMMITTEE
20 JANUARY 2021
PAGE 3
f.Retiring the debt on the Public Works building
g.Use of special funds (City Center funds, Energy projects)
h.Grant monies
i.Approved bonding
Utility rates for the city’s 3 utilities will be increasing slightly in FY22 which will cost consumers a
total of $14.50 more per year.
The average single family home owner will see a total annual increase in property taxes of
$18.76. The average condo owner will pay $13.01 more per year.
In addition to the budget, there will be elected positions on the ballot and a TIF bond issue. All
ballots will be mailed to active voters on about the 10th of February. Ballots can be returned by
mail, dropped off at an outside drop at City Hall, or brought to polling places.
Mr. Hubbard noted that budget books will be available at the end of the month.
Mr. Dorn noted that there will be a $4,000,000+ ballot item to complete Garden Street. This
will be financed through Tax Incremental Financing (TIF) and will be the fourth project to be so
financed.
Ms. Blanchard then described the Garden Street project and showed a slide of the project area.
Work will include curbing, bike facilities, and utilities connections. The project is 100% TIF
eligible and will not result in any tax increase. Ms. Blanchard noted that this year the city has
received over $260,000 from TIF eligible projects including Healthy Living, Allard Square, and
Lake Champlain Housing. Ms. Blanchard added that as other projects are built, the increment
will surpass the debt payment. Mr. Dorn noted the city also has a City Center reserve fund to
augment payments to cover the debt in the early years. Ms. Riehle noted that 2 more City
Center projects have already been permitted, both for market rate housing, which is a very
positive sign.
b.School District Budget:
Supt. Young said that in preparing the FY22 budget, the School Board recognized the pressures
of the pandemic, increased school enrollment, and capital related needs. To address these, the
budget includes minimal staff increases (still below the FY20 levels) and a $2,500,000 bond
issue.
STEERING COMMITTEE
20 JANUARY 2021

The Superintendent noted that South Burlington has been recognized as the #1 School District
and the #1 High School.
The proposed FY22 budget reflects an expenditure increase of 5.88% and a net reduction of
3.59% I spending. Contributing to increased costs are the following:
a.Salary/wages
b.Health Insurance (a significant increase)
c.Equipment repair/maintenance
d.Purchased services
e.Bringing back reductions from FY21
f.One school bus
g.Technology
h.HR software
i.Transportation Dispatcher/Router
j.HR Employment Coordinator
k.Financial Literacy person
l.Teachers at Chamberlin and Marcott to address increased enrollment
m.Non-union Support Staff increase in salary
Supt. Young noted that the PreK-5 enrollment in FY21 was 2527. The projection for FY 22 is an
enrollment of 2574. He then showed a chart indicating the numbers of students in classrooms
in the various schools and the numbers of teachers in those schools. All elementary schools
except for Chamberlin have more than 400 students, some of the largest schools in the state.
The total proposed FY22 school budget is $55,623,080. There is a 7.7% increase in revenue
which will result in the tax rate going down 4.15%. Supt. Young stressed that this is based on a
CLA (common level of appraisal) of 100%. Net spending per pupil would be $16,155.
Supt. Young noted that the State has indicated that the number of equalized pupils is going
down slightly. He said they are working with the State to figure out how this can be possible, so
that number is not to be considered final.
Under the proposed budget, the average condo owner would pay $172. less in school taxes.
The average single family home owner would pay $228. less. Supt. Young showed a review of
the school district’s tax rate history. The 10-year average increase per year is 1.38%. He also
showed a comparison to statewide estimates.
STEERING COMMITTEE
20 JANUARY 2021
PAGE 5
Supt. Young then explained how the CLA works. He noted that he has been told that homes in
the city are selling at or above they appraised value. He then noted that 68% of the city’s voters
qualify for income sensitivity reductions.
Of the 215 Vermont school districts, 107 spend more per equalized pupil than South Burlington
does.
Supt. Young then explained the request for a $2,500,000 bond to address school maintenance
concerns (roofing, floors, doors, etc.). He noted there will also be a ballot article which would
allow the school district to use any FY21 surplus to apply for COVIDD expenses that were not
reimbursed. He read the language for this item.
Mr. Chittenden asked whether the city will have all the reappraisals done for the next tax bill.
Mr. Dorn said he can’t say for certain, but it looks as if that will happen. Supt. Young said that
what people will pay depends on that new appraisal.
Ms. Riehle asked if the bond issue passes whether the first payment is included in the FY22
budget. Supt. Young said it is ($32,000) and covers repairs that are needed immediately. He
cited Burlington High School as an example of what happens when such needs are not
addressed when needed. The Superintendent noted that the Middle School roof is now 20
years old and has a lot of square footage.
4.Legislative Update:
Rep. Lalonde said that Act 48 has been passed out and will allow for the mailing of all ballots.
There is also money to pay for this from the Secretary of State’s office. Another big issue now is
the revenue forecast update. Rep. Lalonde said because things were so dire in December, the
projected yield was lower than it is likely to be. Projections are now much better because of
money from COVID relief funds, and tax rate numbers will probably be lower than what was
projected.
Mr. Barritt said he saw a news item regarding the unfunded portion of the State Teachers
Retirement Fund. He asked whether the schools would have to make up the difference. Rep.
Lalonde said the Fund is in worse shape than they had thought. Treasurer Pearce suggested
some things to address this, but it is premature to say what options will be put in place and
whether there will be a local impact.
STEERING COMMITTEE
20 JANUARY 2021
PAGE 6
Supt. Young said some things are already underway including merger benefits and return of
universal breakfasts. House Bill 35 would eliminate eligible construction costs from the
spending calculation of school districts. House Bill 54 would address how to calculate equalized
pupils. He stressed the need to understand all the factors before changing anything.
Rep. Lalonde said one other bill would address how negotiations are being conducted and what
is negotiable. This could add to local costs. Ms. Fitzgerald noted that she and Ms. Burkhardt
testified on this yesterday.
Sen. Chittenden noted that he has been assigned to the Senate Education Committee. They are
currently reviewing a recent count decision and taking testimony from colleges. They are also
looking at a required Civics course in high schools.
Ms. Riehle commended the School Board on a budget that she can support and thanked them
for “a thankless task.” She then recognized outgoing School Board members Fitzgerald and
Lalonde and thanked them for their many years of service and hard work.
5.Update on 180 Market Street:
Ms. Blanchard noted that the building is officially named South Burlington Public Library and
City Hall. Construction is 75% complete. Work on the Marcott School property is 100%
complete. On the first floor, painting is going on, especially in the Children’s Library. Each floor
is at a different level of completion. Exterior work will be completed in the spring.
A City Council tour of the building is being planned for February or early March. There will also
be a virtual tour which will allow for questions from viewers. Ms. Riehle said she toured the
building with a potential donor last week, and it was very exciting to see the colors. She said
this will be a Library the city will be very proud of.
6.Other Business:
No other business was presented.
As there was no further business to come before the Committee, Mr. Barritt moved to adjourn.
Ms. Fitzgerald seconded. Motion passed unanimously. The meeting adjourned at 7:15 p.m.

CITY COUNCIL PRE-TOWN MEETING 1 MARCH 2021
The South Burlington City Council and South Burlington School Board held a pre-Town Meeting
joint meeting on Monday, 1 March 2021, at 7:30 p.m., via Zoom interactive technology.
CITY COUNCIL MEMBERS PRESENT: H. Riehle, Chair; M. Emery, T. Barritt, Sen. T. Chittenden, D.
Kaufman
SCHOOL BOARD MEMBERS PRESENT: B. Burkhardt, Chair; E. Fitzgerald, M. Lalonde, A. Henry,
ALSO PRESENT: K. Dorn, City Manager; T. Hubbard, Deputy City Manager; C. Holm, HR Director;
J. Rabidoux, Public Works Director; other city staff and members of the public
1.Welcome and Agenda Review: Additions, deletions or changes in order of Agenda
items:
Ms. Emery asked to add a brief discussion of the upcoming Act 250 hearing regarding the
Burton application. Ms. Riehle said this can be on the Thursday evening agenda. Ms. Emery
said it may involve an executive session.
Council members also agreed to address the Consent Agenda following Item #4.
2.Reading of the Warning Articles:
Members agreed to forego the reading of the Warning Articles.
3.Presentation of FY22 Municipal Budget:
Ms. Riehle noted that the presentation will be one that Deputy City Manager Tom Hubbard did
in January so that there would be information available to the public before they received their
ballots by mail.
Ms. Riehle also thanked Department Heads for their work on preparing a budget that taxpayers
can support under these difficult times.
Mr. Hubbard said this is the most challenging budget the City Council has worked on. It includes
sacrifices, some of which have resulted in not being able to maintain a level of service within
every department. The budget does support the Capital Improvement Plan (CIP), but does not
provide full funding.
CITY COUNCIL PRE-TOWN MEETING
1 MARCH 2021
PAGE 2
The total city budget is $50,700,000.00 of which $26,700,000 is in the general fund,
$14,000,000 is in enterprise funds (water, sewer, stormwater), and $10,000,000 in special funds
(e.g., Open Space). The amount to be raised from taxes to support the budget is $17,700,000.
There is a .98% increase in taxes to support this budget. For the average single family home
owner, this results in an increase of $18.76 for the year. For the average condo owner, the
increase in k$13.01 for the year.
Mr. Hubbard then showed a snapshot of the CIP and noted that the Council first looked here for
reductions. Items that were reduced, removed or moved to a future year include trucks for
Public Works, Police cruisers, a reduction in paving from $1,000,000 to $700,000, and a
reduction in ash tree removal. Cuts were also made to reserve funds. Some staff positions
were not filled (e.g., City Planner, Deputy Finance Officer), and 4 positions were combined into
2 positions. Other money-saving actions included switching medical insurance plans (a
reduction from a 12% increase to a 5% increase), using proceeds from the solar installation to
fund energy projects, and streamlining of operations such as payroll, digitizing of records, and
services shared with other communities or organizations.
Expense factors driving the budget include: health insurance, pension plan, agreements with
bargaining units, reduced interest earnings, and most significantly reduced local option tax
receipts. Revenue factors include: a 1% increase in the grand list, rentals at 19 Gregory Drive,
retiring the debt on the Public Works building, local option taxes, and ambulance billing.
The total yearly increase for enterprise funds will be $14.50.
Mr. Hubbard noted that also on the ballot will be 2 City Councilor positions, the City Clerk
position, and a bond for Garden Street.
Mr. Dorn then explained the bond issue which will fund construction at both ends of Garden
Street. He showed an overhead photo and indicated the sections where work will be done.
Other sections of the road will be built by developers. Mr. Dorn noted that if construction costs
can be reduced, there is the possibility of doing work at the White Street intersection. The total
project cost is $4,000,000, and the project is eligible for 100% financing through tax incremental
financing (TIF). Mr. Dorn explained that TIF allows the additional taxes from improved
properties to remain in the city instead of being sent to the state. That money can be used to
fund infrastructure in the TIF district.
CITY COUNCIL PRE TOWN MEETING
1 MARCH 2021
PAGE 3
Mr. Dorn then showed a plan of city center and indicated the buildings which have already been
constructed and the location of 2 new housing projects to be built, one of which is under
construction. The incremental taxes from all of these buildings will pay for 100% of the road
project. There is no additional cost to the taxpayer.
Mr. McHenry asked about a possible connection from the property to the west of City Center
Park. Mr. Dorn said that is unlikely because of wetlands issues.
4.Consent Agenda:
a.Consider and Sign Disbursements
Ms. Emery moved to approve the Consent Agenda as presented. Mr. Barritt seconded. Motion
passed unanimously via a rollcall vote.
8. Presentation of FY22 School District Budget
Ms. Burkhardt thanked the City Manager and Deputy City Manager for their many years of
service to the community.
Ms. Burkhardt then noted the school district’s goals for students:
a.A disposition for lifelong learning
b.Academic proficiency
c.Personal development
d.Citizenship
Students must show proficiency in all of these areas in order to be prepared by their future
paths.
The cost drivers for the proposed school budget include salaries (an additional 4.7 FTE), health
insurance (a 10% increase, negotiated at the state level), and increasing enrollment. Ms.
Burkhardt noted that the demographer is forecasting a continued increase in school enrollment
due to new housing and turnover of existing housing to young families. The High School is over
capacity, and both Marcott and Orchard Schools are at capacity. An additional 21 students are
anticipated at Marcott, 13 at Orchard, and 13 at Chamberlain. An additional teacher has been
CITY COUNCIL PRE-TOWN MEETING
1 MARCH 2021
PAGE 4
added at both Marcott and Chamberlain Schools. Enrollment at the Middle School should be
down by 17 students next year, but the High School will have 14 additional students.
Ms. Burkhardt said it has been a challenge to find staff because of COVID, but they will be
adding the 2 elementary teachers, .3 financial literacy person, .4 guidance (at Orchard), 1
human resource person (to replace the position cut last year), and 1 transportation person.
The total school budget is $55,623,080. The cost per equalized pupil is $16,852.44.
Ms. Burkhardt then explained how the State calculates equalized pupils. They are trying to
determine how the equalized pupil rate went down by 17 students.
There will be a decrease in the tax rate of 5.95%; however, because of reappraisal, individual
taxpayers could see an increase, decrease or no change in their taxes. Ms. Burkhardt noted the
possibility of further changes at the State level which could decrease the tax rate.
There is also a 20-year bond issue for $2,500,000 on the ballot to cover facilities stewardship.
The major item is the replacement of the Middle School roof ($1,800,000). Ms. Burkhardt
noted that research is being done regarding needs at all schools, and there will eventually be a
proposal brought to voters to renovate all school buildings.
Article 4 on the ballot would allow the school district to assign any surplus from the FY21
budget to support unanticipated, non-reimbursable expenses in FY22 related to the COVID
pandemic.
Two School Board positions are also on the ballot. Ms. Burkhardt thanked retiring School Board
members Fitzgerald and Lalonde for their years of service and cited their positive impact on the
city’s schools.
Ms. Fitzgerald acknowledged retiring City Manager Dorn and Deputy City Manager Hubbard.
As there was no further business to come before the Council and School Board, the meeting
was adjourned by common consent at 8:35 p.m.
