South Burlington Planning Commission Virtual Meeting Public Participation Guidelines
1. The Planning Commission Chair presents these guidelines for the public attending Planning Commission meetings
to ensure that everyone has a chance to speak and that meetings proceed smoothly.
2. In general, keep your video off and microphone on mute. Commission members, staff, and visitors currently
presenting / commenting will have their video on.
3. Initial discussion on an agenda item will generally be conducted by the Commission. As this is our opportunity to
engage with the subject, we would like to hear from all commissioners first. After the Commission has discussed an
item, the Chair will ask for public comment.
4. Please raise your hand identify yourself to be recognized to speak and the Chair will try to call on each participant
in sequence. To identify yourself, turn on your video and raise your hand, if participating by phone you may unmute
yourself and verbally state your interest in commenting, or type a message in the chat.
5. Once recognized by the Chair, please identify yourself to the Commission.
6. If the Commission suggests time limits, please respect them. Time limits will be used when they can aid in making
sure everyone is heard and sufficient time is available for Commission to to complete the agenda.
7. Please address the Chair. Please do not address other participants or staff or presenters and please do not
interrupt others when they are speaking.
8. Make every effort not to repeat the points made by others. You may indicate that you support a similar viewpoint.
Indications of support are most efficiently added to the chat.
9. The Chair will make reasonable efforts to allow all participants who are interested in speaking to speak once to
allow other participants to address the Commission before addressing the Commission for a second time.
10. The Planning Commission desires to be as open and informal as possible within the construct that the Planning
Commission meeting is an opportunity for commissioners to discuss, debate and decide upon policy matters.
Regular Planning Commission meetings are not “town meetings”. A warned public hearing is a fuller opportunity to
explore an issue, provide input and influence public opinion on the matter.
11. Comments may be submitted before, during or after the meeting to the Planning and Zoning Department. All
written comments will be circulated to the Planning Commission and kept as part of the City Planner's official
records of meetings. Comments must include your first and last name and a contact (e-mail, phone, address) to be
included in the record. Email submissions are most efficient and should be addressed to the Director of Planning
and Zoning at pconner@sburl.com and Chair at jlouisos@sburl.com.
12. The Chat message feature is new to the virtual meeting platform. The chat should only be used for items
specifically related to the agenda item under discussion. The chat should not be used to private message
Commissioners or staff on policy items, as this pulls people away from the main conversation underway. Messages
on technical issues are welcome at any time. The Vice-Chair will monitor the chat and bring to the attention of
Commissioners comments or questions relevant to the discussion. Chat messages will be part of the official
meeting minutes.
13. In general discussions will follow the order presented in the agenda or as modified by the Commission.
14. The Chair, with assistance from staff, will give verbal cues as to where in the packet the discussion is currently
focused to help guide participants.
15. The Commission will try to keep items within the suggested timing published on the agenda, although published
timing is a guideline only. The Commission will make an effort to identify partway through a meeting if agenda
items scheduled later in the meeting are likely not be covered and communicate with meeting participants any
expected change in the extent of the agenda. There are times when meeting agendas include items at the end
that will be covered “if time allows”.

MEMORANDUM
TO: South Burlington Planning Commission
FROM: Paul Conner, Director of Planning & Zoning
SUBJECT: Draft Environmental Protection Standards & Related Amendments, LDR-20-01
DATE: March 31, 2021 Planning Commission meeting
Enclosed please find the following documents:
• Draft Environmental Protection Standards & Related Amendments (LDR-20-01) [Clean Version]
• Draft Natural Resources Map
• Draft Planning Commission Report
A Red-Line version of the Draft Amendments is posted to the City’s website.
Edits from prior version:
The draft amendments are substantially the same as the draft your received last week. Staff made the
following minor edits based on your discussion:
1. Corrected definitions to reference “Habitat Blocks” and “Habitat Connectors” rather than “Forest
Blocks” and “Forest Connectors”
2. Added the following language to the definition of a Habitat Block: “Habitat Blocks at time of
establishment in these Regulations are greater than 50% forested and totals at least 20 acres in size
(area may, however, extend beyond City boundary). Portions of contiguous forest or shrubland that
cannot be connected by an area wider than 160’ are not considered habitat blocks.”
3. Standardized use of “Level I” and “Level II” – prior drafts sometimes had “Level 1” and “Level 2”
4. Within Section 12.03 (wetlands) added minor clarifying language regarding the statement that impacts
are “generally prohibited” by specifically referencing the sections below that allow for limited impacts
5. Within Section 12.03 (wetlands) made clear that the instances where a modification are permissible are
the only instances where such modifications are permissible
6. Reviewed the text to make sure that “waivers” only refer to actual waiver of requirements (submission
requirements, for instance, and demarcation of resource boundaries by fences IF the DRB finds that
there is sufficient existing demarcation, and using the term “modification” where the DRB has (limited)
authority to modify the extent of a rule
7. Added language regarding fencing adjacent to natural resources that it must allow for passage of wildlife
2
Draft Planning Commission Report
Also enclosed with your packet is a draft Report, as required by State Law, to accompany the proposed
amendments. The Report is required to provide a brief summary and to make findings on three specific
topics, as included. Typically, the Report contains a very brief (1-2 paragraph) summary of the amendments.
In this case, due to the nature of the amendments, staff has proposed more complete summary for the
public to be able to a more full picture without having to read the full text.
The Commission is welcome to add to, remove, or otherwise modify the Report.
Remaining Subject: Southeast Quadrant Natural Resource Protection (SEQ-NRP) Boundary
Staff was asked at the last meeting to evaluate the implications of either including the adjustments to the
SEQ-NRP boundary as discussed in October 2020 now, or saving them for the next round of amendments
that are planned to include other zoning district changes, PUD, Subdivision, Master Plan, and the other
related amendments.
Below is a map showing highlighting the changes discussed in October.
• Green shows the Existing SEQ-NRP Boundary
• Purple shows the SEQ-NRP Boundary as discussed in October 2020
• Blue are the Habitat Blocks and Habitat Connectors
Staff Analysis – SEQ-NRP
3
Virtually all of the proposed areas to be added to the SEQ-NRP are contained within a Habitat Block. The only
exception to this is in South Village, where modifications to the SEQ-NRP were intended to align with the
approved Master Plan.
Considerations / Implications:
• Land within the SEQ-NRP must be excluded from a Planned Unit Development. And land within the SEQ-
NRP does not count towards the minimum 70% open space within a Conservation PUD, and must be
excluded from a traditional neighborhood development altogether.
• Land within the SEQ-NRP cannot be part of any Habitat Block “exchange.” And so, while Section 12.06
allows for limited exchanges of Habitat Block land through one of three options (50’ in any direction to
account for the nature of the mapping; up to 2 acres exchanged to allow for a disconnected tree stand
elsewhere to be protected instead; or larger subject to a Habitat and Disturbance Assessment), these
options are NOT available for any Habitat Block within the SEQ-NRP.
• When the Commission reviewed the habitat block boundaries in October, the discussion began by
reviewing certain areas in the SEQ and then aligning the SEQ-NRP and the Habitat Block. Later in the
same meeting, after reviewing other parts of the City, the Commission returned to a few other parts of
the SEQ. In those later discussions, the Commission elected to keep the zoning di strict boundaries where
they were and instead apply only the new Habitat Blocks. The Commission did not circle back to the
earlier part of the meeting to affirm the approach to take.
• In the intervening time since the October review, it has come to staff’s attention that the current
Regulations’ requirement that maximum lot coverage be met by zoning district may have implications
on existing neighborhoods in the SEQ. In the instance of South Village, the property owners recently
went before the DRB to update their plans to include remaining phases and the proposed commercial
building. When South Village was originally approved, it was all within a single zoning district. More
recently, a substantial portion of the projects is in the SEQ-NRP. Lot coverage was just met as a result.
The addition of land to the SEQ-NRP as proposed may have impacts that have not been evaluated.
Staff recommends that the Commission review this information prior to making a determination of whether to
include the possible changes to the SEQ-NRP at this time or to consider them as part of the full LDR update
package.

ARTICLE 2 DEFINITIONS
[NOTE TO DRAFT: ONLY TEXT WITH CHANGES TO SECTION 2.01 ARE DISPLAYED].
…
2.02 Specific Definitions
…
Building Envelope. A designated area or portion of a lot, delineated on a subdivision plat, within which all
structures, parking and loading areas, and clearing of land must be located, with the exception of driveways
and utility lines. A building envelope shall be defined by minimum setback and maximum height requirements
unless otherwise specified in these Regulations.
Environmental Restoration Project: A project authorized under the MS4 General Permit, TS4 General Permit,
or Municipal Roads General Permit (MRGP), that address a primary pollution source identified in a Vermont
Department of Environmental Conservation approved watershed implementation plan (i.e. TMDL, Flow
Restoration Plan, or Phosphorus Control Plan) and is not required for the purpose of developing or
redeveloping impervious surfaces. Additionally, any floodplain reconnection or stream channel restoration
projects that are not included in a Flow Restoration Plan or Phosphorus Control Plan, but are necessary to
meet the required pollutant reductions in a TMDL.
Habitat Block. Contiguous forested and adjacent unmanaged shrubby areas of old field, young forest, and
unmanaged wetland as demarked on the Natural Resources Map. Includes areas large enough to provide
habitat, either permanently, or seasonally for wider ranging species of wildlife such as bobcat, red and grey
fox, white-tailed deer, river otter and fisher. These species of wildlife require larger areas (than squirrels or
rabbits for example), and a variety of appropriate habitat to fulfill their daily, seasonal, and yearly habitat
needs. These needs include security for breeding activities, a variety of food resources, secure cover for raising
young, and the presence of water- either for drinking or in the case of aquatic species, as a general habitat.
Habitat Blocks fall within a matrix of land-uses that include urban, residential, agricultural, transportation, and
rural uses. Habitat Blocks at time of establishment in these Regulations are greater than 50% forested and
totals at least 20 acres in size (area may, however, extend beyond City boundary). Portions of contiguous forest
or shrubland that cannot be connected by an area wider than 160’ are not considered habitat blocks.
Habitat Connector. Areas in the providing wildlife served by Habitat Blocks the ability to move across the
landscape in stepping-stone fashion between Habitat Blocks as demarked on the Natural Resources Map. For
species such as fox, fisher, and bobcat, accessing multiple Habitat Blocks make up for the smaller, more
fragmented nature of the Habitat Blocks in the community.
Hazard: Floodplain overlay districts A, AE, A1-30, and 0.2% B2, River Corridors except those along intermittent
streams, Very Steep Slopes, Class 1 and Class 2 wetland and associated buffers
Level I Resources: A Habitat Block or Habitat Connector.
LDR-20-01: Environnemental Protection Standards
Draft LDR Amendments March 26, 2021 2
Level II Resources: River Corridors along intermittent streams, Floodplain Overlay District Zone 0.2% B1 (500-
year floodplain, Class 3 wetlands (greater than 300 square feet in size) and associated buffers, and steep
slopes.
Rare, Threatened or Endangered Species. A wildlife or plant species identified by the Vermont Department of
Fish & Wildlife as being rare, threatened or endangered.
Significant Wildlife Habitat. Those natural features that contribute to the survival and/ or reproduction of the
native wildlife of South Burlington. This includes: (1) habitat for rare, threatened and endangered species (state
or federally listed); (2) River Corridors as defined in these regulations; (3) wetlands and wetland buffers as
defined in these Regulations; (4) Habitat Blocks, and (5) Habitat Connectors.
Site Balancing. Where stormwater control and/or treatment of certain limited areas of new, redeveloped, or
substantially reconstructed impervious surface area are not possible, the impact from these areas of untreated
impervious surfaces will be compensated on an equivalent basis by controlling and/or treating other
impervious surfaces on the lot, parcel, or property. This can be accomplished by providing additional control
and/or treatment beyond what is required for impervious surface areas already subject to the requirements
of 12.08(C) or by providing control and/or treatment for impervious surfaces that are not otherwise required
to meet the requirements of 12.08(C). The applicant must own or otherwise control the impervious surfaces
used for site balancing.
Steep Slopes. Any land formation, aside from individual rocks, with a measured slope of between 15 and 25%
containing a vertical drop of at least three (3) feet.
Steep Slopes, Very. Any land formation, aside from individual rocks, with a calculated slope of over 25%
containing a vertical drop of at least three (3) feet.
Stream. A watercourse having a source and terminus, banks, and channel through which waters flow at least
periodically.
Stream, intermittent. Streams with a drainage area smaller than .5 square miles that are not subject
to the River Corridor regulations. This definition shall not include ditches and other constructed
channels primarily associated with land drainage or water conveyance.
Substantial reconstruction. The reconstruction of an impervious surface where an impervious surfac e
currently exists when such reconstruction involves site grading, subsurface excavation, or modification of
existing stormwater conveyance. Substantial reconstruction does not include maintenance or management
activities on impervious surfaces including any crack sealing, patching, cold planning, resurfacing, or reclaiming
treatments used to maintain pavement and bridges, or grading treatments used to maintain unpaved roads.
Undue Adverse Effect. An impact that 1) violates a clear, written community standard under these regulations,
and that 2) cannot be mitigated through siting or design modifications or conditions of approval.
Wetland. An area that is inundated by surface or groundwater with a frequency sufficient to support
vegetation or aquatic life that depend on saturated or seasonally saturated soil conditions for growth and
reproduction. Such areas include, but are not limited to, fens, marshes, swamps, sloughs, potholes, ponds, but
excluding such areas as grow food or crops in connection with farming activities. The boundary of a wetland
shall be delineated by the methodology set forth in the 1989 edition of the Federal Manual for Identifying and
Delineating Jurisdictional Wetlands, or any subsequent amendment or revision of that document. Wetlan ds
are classified as Class I, Class II, or Class III wetlands by the most recently adopted Vermont Wetland Rules.

[NOTE TO DRAFT: ONLY TEXT WITH CHANGES TO SECTION 2.03 ARE DISPLAYED].
Average grade level. The average of the natural or exiting topography at center of all exterior walls of a building
or structure to be placed on site.
Substantial damage. In Floodplain Overlay District Zones A, AE, and A1-30, damage of any origin sustained by
a structure whereby the cost of restoring the structure to its before-damaged conditions would equal or
exceed 50 percent of the market value of the structure before the damage occurred. In Floodplain Overlay
District Zones 0.2% B1 and B2, damage of any origin sustained by a structure whereby the cost of restoring the
structure to its before-damaged conditions would equal or exceed 75 percent of the market value of the
structure before the damage occurred.
Substantial improvement. In Floodplain Overlay District Zones A, AE, and A1-30, any repair, reconstruction,
rehabilitation, addition, or other improvement of a structure after the date of adoption of this bylaw, the cost
of which, over three years, or over the period of a common plan of development, cumulatively equals or
exceeds 50 percent of the market value of the structure before the “start of construction” of the improvement.
In Floodplain Overlay District Zones 0.2% B1 and B2, any repair, reconstruction, rehabilitation, addition, or
other improvement of a structure after the date of adoption of this bylaw, the cost of which, over three years,
or over the period of a common plan of development, cumulatively equals or exceeds 75 percent of the market
value of the structure before the “start of construction” of the improvement.
This term includes structures which have incurred “substantial damage”, regardless of the actual repair work
performed. The term does not, however, include either: (a) Any project for improvement of a structure to
correct existing violations of state or local health, sanitary, or safety code specifications which have been
previously identified by the local code enforcement official and which are the minimum necessary to assure
safe living conditions or (b) Any alteration of an “historic structure”, provided that the alteration will not
preclude the structure’s continued designation as an “historic structure”.

Undue Adverse Effect
LDR-20-01: Environnemental Protection Standards
Draft LDR Amendments March 26, 2021 5
Figure 3-0 Determining Undue Adverse Effect
The following test shall be used by the Development Review Board in all circumstances when the South Burlington Land
Development Regulations requires the Development Review Board to determine whether or not an undue adverse effect is being
created.
1. First, the Development Review Board shall determine if a proposed project will have an adverse effect upon the resource,
issue and/or facility in question. The Development Review Board shall determine such by responding to the following
question:
(a) Will the project have an unfavorable impact upon the resource, issue and/or facility in question?
2. If it is determined by the Development Review Board that an adverse effect will be being created by a project, the
Development Review Board shall then determine if the adverse effect is “undue.” To determine whether or not an adverse
effect is undue, the Development Review Board shall respond to the following two questions:
(a) Will the project conflict with a clear, written standard in these regulations or the Municipal Plan applicable to the
resource, issue or facility in question?
(b) Can the unfavorable impact be avoided through site or design modifications, or mitigation, or other conditions of
approval?
The Development Review Board shall conclude that adverse effect is “undue” if the answer to 2(a) is YES OR the answer to 2(b) is
NO.

[NOTE TO DRAFT: ONLY TEXT WITH CHANGES WITHIN ARTICLE 9 ARE DISPLAYED].
9.06 Dimensional and Design Requirements Applicable to All Sub-Districts
…
B. Open Space and Resource Protection.
(1) Open space areas on the site shall be located in such a way as to maximize opportunities for
creating usable, contiguous open spaces between adjoining parcels, creating or enhancing stream buffer
areas, or creating or enhancing buffers for primary or secondary natural communities.
(2) Building lots, streets and other structures shall be located in a manner consistent with the
Regulating Plan for the applicable sub-district, allowing carefully planned development at the average
densities provided in this bylaw.
(3) A plan for the proposed open spaces and/or natural areas and their ongoing management shall
be established by the applicant. Such plan shall describe the intended use and maintenance of each area.
Continuance of agricultural uses or enhancement of wildlife habitat values in such plans for use and
maintenance is encouraged. Existing natural resources on each site shall be protected through the
development planIn making this finding the Development Review Board shall use the provisions of Articles
10 and 12 of this bylaw related to Hazards, Level I Resources, and Level II Resources.
(4) Sufficient grading and erosion controls shall be employed during construction and after
construction to prevent soil erosion and runoff from creating unhealthy or dangerous condit ions on the
subject property and adjacent properties. In making this finding, the Development Review Board may rely
on evidence that the project will be covered under the General Permit for Construction issued by the
Vermont Department of Environmental Conservation.
C. Agriculture. The conservation of existing agricultural production values is encouraged through
development planning that supports agricultural uses (including but not limited to development plans that
create contiguous areas of agricultural use), provides buffer areas between existing agricultural operations
and new development, roads, and infrastructure, or creates new opportunities for agricultural use (on any soil
group) such as but not limited to community-supported agriculture. Provisions that enhance overall
neighborhood and natural resource values rather than preservation of specific soil types are strongly
encouraged.
9.12 SEQ-NRP; Supplemental Regulations
A. Any lot that lies entirely within a SEQ-NRP sub-district is subject to the following supplemental
regulations:
(1) Such lot shall be conveyed to the City of South Burlington as dedicated open space or to a qualified
land trust and shall not be developed with a residence, or
(2) Such lot may be developed with a residence or residences pursuant to a conservation plan
approved by the Development Review Board. See 9.12(B) below.
(3) Such lot may be developed with uses other than residences, as listed in Table C-1, subject to the

the construction and use of a single family dwelling unit in compliance with these Regulations, and;
(b) The location of structures, yards, and access drives have no portion within a Hazard, Level I
Resource, Level II Resource or their related buffers.
(2) Where the lot is fifteen (15) acres or more in contiguous area, the Development Review Board
may allow a subdivision of no more than three (3) lots and construction of one (1) single family dwelling
unit on each of these lots only if:

10 OVERLAY DISTRICTS FP, TR, SVP, IHO, TO, UDO, RCO
10.01 Floodplain Overlay District (FP)
[NOTE TO DRAFT: SECTION 10.01 IS A COMPLETE REPLACEMENT OF THE EXISTING TEXT].
A. Purpose. It is the purpose of the Floodplain Overlay District to:
1. Avoid and minimize the loss of life and property, the disruption of commerce, the impairment of the tax
base, and the extraordinary public expenditures and demands on public services that result fro m
flooding;
2. Ensure that the selection, design, creation, and use of development is reasonably safe and accomplished
in a manner that is consistent with public wellbeing, does not impair flood plain services or the stream
corridor;
3. Manage the flood hazard area designated pursuant to 10 V.S.A. Chapter 32 § 753, the municipal hazard
mitigation plan; and make the City of South Burlington, its citizens, and businesses eligible for federal
flood insurance, federal disaster recovery funds, and hazard mitigation funds as may be available.
B. Authority. In accordance with 10 V.S.A. Chapter 32, and 24 V.S.A. Chapter 117 §4424, §4411 and §4414,
there is hereby established a bylaw for areas at risk of flood damage in the City of South Burlington
Vermont. These regulations shall apply to development in all areas in the City of South Burlington
identified as within the Floodplain Overlay District designated in Section 3.01(B).
C. [reserved]
D. Administration
1. Floodplain Review. All development in the City of South Burlington located within the Floodplain
Overlay District shall be subject to Floodplain Review. The Floodplain Overlay District overlays other
existing zoning districts. All other requirements of the underlying district shall apply in addition to the
provisions herein, unless otherwise indicated. The Floodplain Overlay District is composed of two
areas:
a. Floodplain Overlay District Zones A, AE, and A1-30. The boundaries of these Zones include
those areas of special flood hazard designated in and on the most current flood insurance
studies and maps published by the Department of Homeland Security, Federal Emergency
Management Agency, National Flood Insurance Program and mapped as Zones A, AE, or A1-
30.
b. Floodplain Overlay District Zones 0.2% B1 and B2. The boundaries of these Zones include
those areas of special flood hazard designated in and on the most current flood insurance
studies and maps published by the Department of Homeland Security, Federal Emergency
Management Agency, National Flood Insurance Program, and on Map ****, and Map ***, and
mapped as Zone 0.2% B1 and Zone 0.2% B2. Floodplain Overlay District Zone 0.2% B1 is
composed of areas of the 500-year floodplain that are already substantially developed and
where additional opportunities for infill development is appropriate. Floodplain Overlay
District Zone 0.2% B2 is composed of areas of the 500-year floodplain that are not developed
and where future development is not appropriate.

District boundary, the following procedure shall be followed:
a. If uncertainty exists with respect to the boundaries of the Floodplain Overlay District Zones A,
AE, and A1-30 the location of the boundary shall be determined by the Administrative Officer.
If the applicant disagrees with the determination made by the Administrative Officer, a Letter
of Map Amendment from FEMA shall constitute proof that the property is not located within
the Special Flood Hazard Area.
b. If uncertainty exists with respect to the boundaries of the Floodplain Overlay District Zones
0.2% B1 and B2 the location of the boundary shall be determined by the Administrative
Officer. If the applicant disagrees with the determination made by the Administrative Officer,
the applicant may appeal the determination in accordance with Article 17.
3. Base Flood Elevations and Floodway Limits.
a. Where available (i.e. zones A1-A30, AE, AH, and 0.2% B1 within the floodplain of the Winooski
River), the base flood elevations and floodway limits (or data from which a community can
designate regulatory floodway limits) provided by the National Flood Insurance Program in
the Flood Insurance Study and accompanying maps shall be used to administer and enforce
the provisions of these regulations.
b. In Zone A of the Floodplain Overlay District where base flood elevations and floodway limits
have not been provided by the National Flood Insurance Program in the Flood Insurance Study
and accompanying maps, it shall be the responsibility of the applicant to develop the base
flood elevation at the site using data available from state or federal agencies or other sources.
4. Warning of Disclaimer of Liability. This bylaw does not imply that land outside of the areas covered
by this overlay district will be free from flood damages. These regulations shall not create liability on
the part of the City of South Burlington, or any municipal official or employee thereof, for any f lood
damages that result from reliance on these regulations, or any administrative decision lawfully made
hereunder.
5. Precedence of Bylaw. The provisions of this Floodplain Overlay District shall not in any way impair or
remove the necessity of compliance with any other local, state, or federal laws or regulations. Where
these regulations imposes a greater restriction the provisions here shall take precedence.
6. Exempted Development. The following types of development are exempt from Floodplain Review.
The following types of development may also still be subject to other standards in the South Burlington
Land Development Regulations including Section 12.01 General Stream and Surface Water Protection
Standards:

(1) Establish protection of the river corridor to provide rivers and streams with the lateral space
necessary to maintain or reestablish floodplain access and minimize erosion hazards through natural,
physical processes;
(2) Allow for wise use of property within river corridors that minimizes potential damage to existing
structures and development from flood-related erosion;
(3) Discourage encroachments in undeveloped river corridors;
(4) Protect and improve the quality of surface waters and streams within the City of South Burlington;
and
(5) Provide sufficient space for wildlife habitat along rivers and streams.
(4) Provide allowances for infill and redevelopment of designated centers that are within river corridors.
B. Authority. In accordance with 24 V.S.A. Chapter 117, §4424, and §4414, there is hereby established a
bylaw for areas at risk of erosion damage in the City of South Burlington Vermont. These regulations shall
apply to development in all areas in the City of South Burlington identified as within the River Corridor Overlay
District designated in Section 3.01(B).
LDR-20-01: Environnemental Protection Standards
Draft LDR Amendments March 26, 2021 20
C. Comprehensive Plan. These regulations hereby implement the relevant portions of the City of South
Burlington's adopted Comprehensive Plan and are in accord with the policies set forth therein.
D. Warning of Disclaimer of Liability. This bylaw does not imply that land outside of the areas covered
by this overlay district will be free from erosion damages. This regulation shall not create liability on the part
of the City of South Burlington, or any municipal official or employee thereof, for any erosion damages that
result from reliance on this regulation, or any administrative decision lawfully made hereunder.
E. Precedence of Bylaw. The provisions of this River Corridor Overlay District shall not in any way impair
or remove the necessity of compliance with any other local, state, or federal laws or regulations. Where this
regulation imposes a greater restriction, the provisions in these regulations shall take precedence.
F. District General Provisions
(1) Establishment of RCO District. The RCO is an overlay district. All other requirements of the
underlying district, or another overlay district such as the Flood Hazard Overlay District, shall apply in
addition to the provisions herein, unless it is otherwise so indicated. If there is a conflict with another
such district, the stricter provision shall apply.
(2) RCO District Boundaries. The boundaries of the RCO District are as follows:
(a) All River Corridors as published by the Vermont Agency of Natural Resources (including the
Statewide River Corridors and refinements to that data based on field-based assessments which are
hereby adopted by reference).
(b) All land within one hundred (100) feet horizontal of the top of bank or top of slope, whichever
is applicable given the stream’s fluvial geomorphology, along the reaches of the main stem of Potash
Brook where a mapped River Corridor has not been developed by the Vermont Agency of Natural
Resources.
(c) All land within fifty (50) feet horizontal distance from the top of bank or top of slope,
whichever is applicable given the stream’s fluvial geomorphology, of all other perennial rivers and
streams.
(d) All land within ten (10) feet horizontal distance from the top of the bank or top of slope of a
natural intermittent stream, whichever is applicable given the stream’s fluvial geomorphology.
(e) Requests to update a River Corridor map shall be in accordance with the procedure laid out
in the ANR Flood Hazard Area and River Corridor Protection Procedure.
(3) RCO District – Classification. River Corridors shall be classified in the following manner per Section
12.01:
(a) River Corridors on Intermittent Streams. River Corridors on intermittent streams are Level II
Resources.
(b) All Other River Corridors. River Corridors on all other streams shall be considered a Hazard
resources.
(4) Jurisdictional Determination and Interpretation. The information presented on any maps, or
contained in any studies, adopted by reference, is presumed accurate. If uncertainty exists with respect
to the boundaries of the RCO the location of the boundary on the property shall be determined by the
LDR-20-01: Environnemental Protection Standards
Draft LDR Amendments March 26, 2021 21
Administrative Officer (AO). If the applicant disagrees with the determination made by the AO or the river
corridor as mapped, the applicant has the option to either:
(a) Hire a licensed land surveyor or registered professional engineer to stake out the RCO
boundary on the property; or
(b) Request a letter of determination from ANR which shall constitute proof of the location of the
river corridor boundary. In support of a letter of determination request, applicants must provide ANR
a description of the physical characteristics that bring the river corridor delineation into question (e.g.
the presence of bedrock or other features that may confine lateral river channel adjustment. When
ANR receives a request for a letter of determination, ANR evaluates the site and existing data to see if
a change to the river corridor delineation is justified, necessitating a river corridor map update. An
ANR letter of determination will either confirm the existing river corridor delineation or will result in
an update to the river corridor delineation for the area in question. If a map update is justified, an
updated map will be provided with the letter of determination.

12.08 Stormwater Management
A. Purpose. The purpose of this section is:
(1) To promote stormwater management practices that maintain pre-development hydrology through site
design, site development, building design and landscape design techniques that infiltrate, filter, store,
evaporate and detain stormwater close to its source;
(2) To protect water resources, particularly streams, lakes, wetlands, floodplains and other natural aquatic
systems on the development site and elsewhere from degradation that could be caused by construction
activities and post-construction conditions;
(3) To protect other properties from damage that could be caused by stormwater and sediment from
improperly managed construction activities and post-construction conditions on the development site;
(4) To reduce the impacts on surface waters from impervious surfaces such as streets, parking lots,
rooftops and other paved surfaces; and
(5) To promote public safety from flooding and streambank erosion, reduce public expenditures in
removing sediment from stormwater drainage systems and natural resource areas, and to prevent
damage to municipal infrastructure from inadequate stormwater controls.
B. Applicability
(1) These regulations will apply to all development within the City of South Burlington where one-half acre
or more of impervious surface area exists or is proposed to exist on an applicant’s lot or parcel.
(2) If the combination of new impervious surface area created and the redevelopment or substantial
reconstruction of existing impervious surfaces is less than 5,000 s.f. then the application is exempt from
requirements in this Section 12.08.
(3) Applications meeting the criteria set forth in section 12.08(B)(1), and not exempt under section
12.08(B)(2), shall meet the application requirements in Section 12.08(C) and the site design
requirements in section 12.08(D) as follows:
(a) If the area of the lot or parcel being redeveloped or substantially reconstructed is less than 50%
of the lot’s existing impervious surface area, then only those portions of the lot or parcel that are
being redeveloped or substantially reconstructed must comply with all parts of Section 12.08(D).
All new impervious surface area must meet the site design requirements of section 12.08(D).
(b) If the area of the lot or parcel that is being redeveloped or substantially reconstructed exceeds
50% of the lot or parcel’s existing impervious surface area then all of the lot or parcel’s impervious
surfaces must comply with all parts of Section 12.08 (D). All new impervious surface area must
meet the site design requirements of Section 12.08(D).
C. Application Requirements. Applicants required to comply with Section 12.08 shall provide the following

(rainfall amounts to be determined using NOAA, Atlas 14 data and a type II rainfall distribution). Any
TR-55 based model shall be suitable for this purpose. The intent of the twenty-five year storm event
analysis is to ensure the proposed project does not overload an existing downstream drainage
structure(s) and result in damage to private or public infrastructure or property. The analysis is also
intended to ensure that stormwater infrastructure installed as a part of a development can
accommodate future upstream development.
(7) The applicant’s engineer must provide such information as the stormwater superintendent or designee
deems necessary to determine the adequacy of all drainage infrastructure.

approval of the Development Review Board,
then the WQv shall be treated on the lot using Tier 2 practices as described in the most recently
adopted version of the VSMM. A site with an existing Tier 3 practice is allowed to evaluate
retrofitting/expanding this practice to meet the requirements of Section 12.08(D)(2). Existing Tier
3 practices shall only be used to satisfy the requirements of Section 12.08(D)(1) in accordance with
the Water Quality Practice Selection Flowchart in the VSMM.
(2) The post-construction peak runoff rate for the one-year, twenty-four hour (rainfall amounts to be
determined using NOAA, Atlas 14 data and a type II rainfall distribution) rain event shall not exceed the
existing peak runoff rate for the same storm event from the site under conditions existing prior to
submittal of an application.

requirements of Section 12.08(D), or sites that are exempt from §12.08(D), may discharge to the municipal
stormwater system, or a stormwater system within a proposed future municipal right-of-way, provided
that the stormwater system has adequate capacity to convey the twenty-five year storm event from the
contributing drainage area. All applicants shall meet the following standards if it is determined that their
project may have impacts to municipal stormwater system:
(1) New drainage structures connected to the municipal stormwater system, or a stormwater system
within a proposed future municipal right-of-way, shall comply with the following standards:
(a) New drainage structures should be located within the street right-of-way

Proposed Land Development Regulations
Amendment & Adoption Report
Planning Commission Public Hearing *****, 2021
In accordance with 24 V.S.A. §4441, the South Burlington Planning Commission has prepared the
following report regarding the proposed amendments and adoption of the City’s Land Development
Regulations.
Outline of the Proposed Overall Amendments
The South Burlington Planning Commission will hold a public hearing on *********** 2021 at 7:00 pm,
via GoToMeeting electronic platform, to consider the following amendments to the South Burlington
Land Development Regulations:
LDR-20-01: Modifications to Environmental Protection Standards, including existing 100-year floodplain,
river corridor, stream buffer, wetland & wetland buffer, and stormwater management standards;
establishment of standards regarding 500-year (0.2%) floodplain, habitat block, habitat connector, steep
slope, and very steep slope standards; establishment of criteria to evaluate undue adverse effect; and
related amendments referencing the above-listed resources.
Brief Description of the Proposed Amendments
The proposed amendments include the following:
• Enhancement of standards and/or geographic area for protection of natural resources currently
regulated by the City: notably 100-year floodplains, class I and II wetlands, streams, and river
corridors
• Mapping and establishment of standards for newly-regulated natural resources: habitat blocks,
habitat connectors, steep slopes, and 500-year floodplains
• Update of stormwater management and 100-year floodplain standards to current best practices
and streamlining of review for public stormwater restoration projects
• Update of references to natural resources throughout the regulations to be directed to the
Environmental Protection Standards of Articles 10 and 12
• Establishing thresholds and consistent standards of review applicable to limited allowances for
impacts to regulated natural resources, including infrastructure
• Categorization of regulated natural resources into three tiers

Categories of Natural Resources
Resources are grouped into three (3) categories: Hazards, Level I Resources, and Level II Resources.
• Hazards are resources for which impacts can have significant effects on safety of property or
life. They are often regulated at the State or Federal level. They may be large or small in area.
Very limited incursions into these resources, particularly for certain infrastructure, may be
permitted following review.
• Level I Resources are locally-identified natural resources that are typically larger in area and
cross multiple properties. The draft regulations allow for limited adjustment of boundaries in
certain circumstances and limited incursions under specific circumstances. Credit may be
provided for the conservation of these areas through density transfers in certain Planned Unit
Development types.
• Level II Resources require specific review for any impact, but are not necessarily excluded from
development parcels. They are typically smaller in area and/or can be mitigated through careful
site design.
Background and Context of the Proposed Regulations
The proposed modifications to the Regulations draw on the research work of prior Planning Commission
efforts, the 2016 Comprehensive Plan, and several studies undertaken by the community in recent
years, including the 2015 Open Space Plan, the 2020 Habitat Block and Assessment and Ranking, and the
2020 Interim Zoning Open Space Committee Final Report, among others.
Standards and geographic boundaries established by these Regulations were developed based on
mapping, research, and consultations with subject area experts. Habitat Blocks and Habitat Connectors
included in the proposed Regulation used the 2020 Habitat Block Assessment and Ranking as their
starting point. Geographic boundaries, thresholds, standards for allowed modifications or incursions
were subsequently established.
These draft amendments are proposed to function as one of a collection of tools to support natural
resource conservation and thoughtful development in the community in support of the Comprehensive
Plan.
Findings Concerning the Proposed Amendments
The proposed amendments have been considered by the Planning Commission for their consistency
with the text, goals, and objectives of the City of South Burlington’s Comprehensive Plan, adopted
February 1, 2016. For each of the amendments, the Commission has addressed the following as
enumerated under 24 VSA 4441(c):
“…The report shall provide a brief explanation of the proposed bylaw, amendment, or repeal and shall
include a statement of purpose as required for notice under section 4444 of this title, and shall include
findings regarding how the proposal:
(1) Conforms with or furthers the goals and policies contained in the municipal plan, including the
effect of the proposal on the availability of safe and affordable housing.
(2) Is compatible with the proposed future land uses and densities of the municipal plan.
4
The 2016 Comprehensive Plan establishes four (4) principal Goals for the City:
Vision & Goals. Here and into the Future, South Burlington is…
Affordable & Community Strong Creating a robust sense of place and opportunity for our residents and
visitors.
• Be affordable, with housing for people of all incomes, lifestyles, and stages of life;
• Keep unique features, and maintain or enhance the quality of life of existing neighborhoods;
• Be a recognized leader in public education offerings and outcomes;
• Provide quality public safety, infrastructure, health, wellness, and recreation services;
• Ensure transparent and accessible government.
Walkable. Bicycle and pedestrian friendly with safe transportation infrastructure.
• Develop a safe and efficient transportation system that supports pedestrian, bicycle, and transit
options while accommodating the automobile;
• Establish a city center with pedestrian-oriented design, mixed uses, and public buildings and civic
spaces that act as a focal point to the community.
Green & Clean. Emphasizing sustainability for long-term viability of a clean and green South Burlington.
• Promote conservation of identified important natural areas, open spaces, aquatic resources, air
quality, arable land and other agricultural resources, historic sites and structures, and recreational
assets;
• Reduce energy consumption city-wide and increase renewable energy production where appropriate.
Opportunity Oriented. Being a supportive and engaged member of the larger regional and statewide
community.
• Prioritize development that occurs within the community into the higher intensity areas identified
within this Plan;
• Support a diverse and vibrant economy built on quality jobs, employment centers and a supportive
educational and research system; support markets for local agricultural and food products.
The 2016 Comprehensive Plan also includes the following objectives and strategies specific to ecological
resources in the community:
Ecological Objectives
Objective 30. Proactively plan for a network of interconnected and contiguous open spaces to conserve and
accommodate ecological resources, active and passive recreation land, civic spaces, scenic views and vistas, forests
and productive farmland and primary agricultural soils.
Objective 31. Conserve, restore and enhance biological diversity within the City, through careful site planning and
development that is designed to avoid adverse impacts to critical wildlife resources, and that incorporates
significant natural areas, communities and wildlife habitats as conserved open space.
2-107
Ecological Strategies
Strategy 67. Substantially restrict new subdivision and development from primary resource conservation areas to
include hazardous and environmentally sensitive areas identified, mapped and regulated by the City. Minimize the
adverse impacts of new subdivision and development, including resource fragmentation and encroachment, within
secondary resource conservation areas, to include those resources of state or local significance as indicated on
available resource maps, identified in available inventories and studies, and confirmed through site investigation.
Strategy 68. Redefine open space in new developments such that usable, quality open space shall be required.
Qualifying open space should include civic spaces, recreation, wildlife habitat, and usable agricultural lands.
5
Strategy 69. Retain healthy and high-quality existing trees, vegetation, and publicly owned natural areas and
woodlands. Develop long-range management plans for each area to foster their continued health and use.
Strategy 70. Encourage public education about tree functions and tree disease inspection in urban areas through
cooperation with the UVM Horticultural Farm and Vermont Department of Forest Parks, and Recreation, Urban and
Community Forestry Program.
Strategy 71. Maintain the City’s wildlife diversity, including making use of available planning and legal tools such as
buffers, transfers of development rights, overlay zoning districts, conservation easements and other tools as
appropriate.
Strategy 72. Work with adjoining municipalities and regional entities to enact complementary land use policies
where wildlife habitat areas cross City boundaries.
Strategy 73. Maintain existing overall tree canopy. Set targets to increase overall tree canopy, with a focus on
increasing tree canopy in urban areas and residential property parcels as identified in the Report on Existing and
Potential Tree Canopy in the City of South Burlington (2014).
Strategy 74. Foster passive recreational use of natural areas and identify areas that may be appropriate for an “off
-limits” designation due to their fragile nature.
And finally, the Comprehensive Plan establishes a series of five categories of Future Land Use, as
depicted on Map 11, along with the following statement: “Together, these broad categories are
intended to encompass key issues and areas addressed in this Comprehensive Plan and provide an
overall framework for implementation of the plan.”
• Very low intensity, principally open space.
• Lower intensity, principally residential
• Medium intensity, residential to mixed use
• Medium to higher intensity, principally non-residential
• Medium to higher intensity, mixed use
The proposed Regulations substantively and substantially advance the ecological goals and strategies
enumerated in the 2016 Comprehensive Plan, and do so in the context of the overall Vision and Goals
for the City and the designations within the Future Land Use Map.
The proposed regulations have been prepared following detailed evaluation of each individual resource
as well as their collective and coordinated roles in support of the objectives and strategies above.
The specific resources included within the draft Environmental Protection Standards are not intended to
be a precise replication of the individual resources as described or mapped in the Comprehensive Plan;
South Burlington-specific study and analysis of these resources, consideration of best practices in
resource conservation, and consideration of the geographic context of natural resources across the City
were important factors in developing regulatory tools to implement these objectives and strategies.
The amendments have been considered for their impacts on the availability of safe and affordable
housing. Establishing restrictions on certain land as priority areas for conservation of natural resources
can affect the total land area available for the construction of new housing. The existing and proposed
regulations mitigate the effects of this conservation, through several means:
6
• Existing regulations allow for the re-allocation of allowable housing density within a property
through the use of Planned Unit Developments.
• The draft Regulations accommodate circumstances where certain natural resources – notably
Habitat Blocks and Habitat Connectors - are present across the substantial majority of the land.
• The draft regulations provide for reduced standards, exemptions, or allowable modifications
within areas designated as Medium to Higher Intensity in the Future Land Use Map
• Recent prior amendments to the Land Development Regulations have increased building height
allowances along principal transportation corridors, established inclusionary zoning
requirements, and reduced or eliminated minimum parking standards
• The proposed regulations are intended to provide greater clarity and certainty for all parties
involved in land development
(3) Carries out, as applicable, any specific proposals for any planned community facilities.
The proposed amendments do not directly affect planned community facilities. Planned Community
facilities are specifically addressed through reference to the Official Map.
SOUTH BURLINGTON PLANNING COMMISSION
MEETING MINUTES
3 MARCH 2021
1
The South Burlington Planning Commission held a special meeting on Wednesday, 3 March
2021, at 7:00 p.m., via Go to Meeting remote technology.
MEMBERS PRESENT: J. Louisos, Chair; B. Gagnon, T. Riehle, M. Ostby, M. Mittag, D. Macdonald,
P. Engels
ALSO PRESENT: P. Conner, Director of Planning and Zoning; J. Nick, A. Luzzato, C. Long, S.
Dooley, F. Von Turkovich, A. Jensen-Vargas, S. Partilo, A. Chalnick, R. Greco
1. Agenda: Additions, deletions or changes in order of agenda items:
No changes were made to the agenda.
2. Open to the public for items not related to the Agenda:
No issues were raised.
3. Planning Commissioner announcements and staff report:
There were no announcements or staff report.
4. Continued Land Development Regulations Work Session:
a. Review of provisions for waivers/alternative development standards in the draft
LDRs:
Mr. Nick noted that the Hill Farm has a lot of forest blocks, wetlands, etc. He asked if there is
some flexibility. He also noted a fair amount of invasives on the edges. One concern is that if
there are house lots, there is a question of who owns the woodlands. He wanted to encourage
kids to get outside, and there is an opportunity to have house lots with some woodlands (50
feet into the woods). He cited the Deer Run development where very few trees were removed.
There are no pools in the woods, and there is plenty of wildlife. Another concern is that he
wouldn’t want the regulations to preclude Swift St. Extension or Exit 12B. He noted the number
of times he has heard “what you’re saying makes sense, but that’s not what the regulations
say” in his work in various communities. He asked members to keep that in mind. Ms. Louisos
thanked Mr. Nick for that feedback.
2
Regarding waivers, Ms. Louisos questioned how much flexibility to allow. She felt flexibility for
better design was OK and suggested that “waiver” may not be the best word. Mr. Conner
agreed and said “waiver” usually means doing away with something. A modification is more
typical of what is done (e.g., reducing a setback by a foot or so for a better project). There is
also a provision for “alternative compliance” as in City Center. “Show us something better.”
Ms. Ostby questioned whether the Commission had decided that 25 percent will be the number
for steep slopes for Level 1. Mr. Conner said that is in the draft, but it can be changed if the
Commission chooses to. Ms. Ostby felt they would have to circle back to that at some point.
Mr. Riehle said he doesn’t care what the angle is as long as it doesn’t create erosion. He felt
they may not need a percentage.
Mr. Riehle then asked about zoning district boundaries and the ability to apply the regulations
of one district 50 feet into an adjacent district. He asked about buffering. Mr. Conner said
there is a buffer required from a commercial to a residential district. If the uses are the same,
there is no buffer required. Mr. Riehle asked about 4-plexes put down behind single family
homes. Mr. Conner said the rule is that a building can’t be more than one story higher than
buildings in an adjacent area.
Mr. Macdonald asked if there is any other district other than City Center where there can be
impact to a Class 2 wetland. He cited the proposed industrial park on Rt. 116 which is targeted
for office/commercial use. He asked if development would be eliminated there because of the
wetland. He saw that as an “unintended consequence” since that’s where the city is looking for
jobs, etc. He would like to see that area lumped in with the City Center regulations. Ms. Ostby
noted that area would also be involved if the 12B interchange is built. She felt it might have to
be revisited in the future, but in the meantime supported sticking with the wetland plan.
Mr. Gagnon noted they had talked about this and agreed regarding wetland buffers and
whether to allow any disturbance in the buffer. Currently this can happen with mitigation, but
the Commission decided not to allow impact on the buffers. He was concerned with saying one
area is different from another and having people ask for more exceptions. Ms. Louisos noted
they went with a moderate approach by not making the buffers any wider.
Ms. Louisos asked for public comment. There was none made.
b. Traditional Neighborhood Development PUD Type Review: debrief on
presentation/illustrations from 2/23, feedback on the results of TND development
calculator; discuss potential adjustments to the “levers” affecting development
and other TND design elements; overview of “mixed-use” component:
3
Mr. Mittag questioned the 11C table and said he was proposing to make concerned with
making things more comfortable for people who may continue to work from home. Mr. Conner
asked Mr. Mittag to share his thoughts with him directly to help with drafting.
Mr. Conner asked members if anything from Mark Kane’s presentation “jumped off the page”
that they weren’t expecting.
Mr. Riehle said he still has an issue of tri and quad plexes and the purpose of the Southeast
Quadrant (SEQ). He felt inclusions of those units could change the SEQ so it is no longer the
rural part of the city. He noted that 3 Burlington City Council members have “fled” to South
Burlington’s SEQ. Mr. Riehle also felt the tri and quad plexes would also probably be rental
units, and he didn’t feel that renter support the city with taxes, etc.
Ms. Louisos said if they break up the land into 1.2 acre pieces, you can see the houses, but you
use up more land. She acknowledged that a quadplex in the middle of nowhere could look
imposing.
Mr. Gagnon said one of the things used to address the quadplex is the construction style which
would have the buildings look like single family homes. There would also be a matched look
and feel of the houses in the neighborhood. He felt they should make sure building types
match a neighborhood. Regarding renters, Mr. Gagnon said this can be great or not so great,
and he didn’t know how to address that. He noted that there are single family homes rented to
students, and that can’t be banned.
Ms. Louisos suggested a possible limit on some types of houses in a location. The multi-family
homes could be in the center, and certain groupings could create a homogeneous sense.
Ms. Ostby urged members to be more open-minded about renters. She noted that 40% of
South Burlington residents are renters, and they pay taxes through their rents. She added that
it is very difficult to be homeowners these days, and renters can be very vibrant members of
the community.
Mr. Mittag was concerned with crafting regulations recommended that regulations be written
that anyone can understand. Ms. Louisos said that Mr. Kane had said it was a junior person in
the company who drew the plans from the text.
Mr. Conner said he had a debrief with Mr. Kane after the presentation. They felt it might make
sense to cap the percentage of multi-family homes and to stress that multi-family buildings
types would have the form and feel of a single family home. Mr. Conner also noted that the
biggest challenge the drafter had was to hit the numbers exactly. The suggestion is to give the
4
DRB a 3-4% ability to deal with unique circumstances. Ms. Ostby felt that was a good idea. She
noted that everything she tried always had a little land left over.
Ms. Jensen-Vargas said she is a renter, and the ability of not having to deal with upkeep (e.g.,
mowing, plowing, etc.) gives her more time to do more for her community. It also reduces
heating costs, which makes it more affordable.
Ms. Dooley noted there are already places in the SEQ with multi-family units (e.g. South
Village). She also pointed out Bayberry Commons in Burlington which has some interesting
streets. Some buildings look like duplexes, but in the back there are 2 more units. She cited
the importance of the neighborhood feel.
Mr. Riehle asked about the 10 units mentioned on one page. Mr. Conner said that is a total of
housing units: two 3-plexes and one 4-plex.
Ms. Ostby reminded members that development can be more dense because they are
conserving more land. Mr. MacDonald said that is a good point, but he wasn’t sure how to
explain that to the public. He was concerned that the building type approach still leaves gaps as
to density. Mr. Conner said the maximum allowable density isn’t necessarily what developers
are looking for. Having building types, percentages, etc., is providing more certainty.
Mr. Chalnick said some properties won’t look very different. If they don’t have hazards, etc.,
there could be a huge number of houses. He wasn’t sure that much more land is being
conserved. Mr. Mittag took issue with the word “conserved.” It is not necessarily more
conserved space but more open space in the development. Ms. Ostby said they have also
added hazards and level 1 resource areas that can’t be built on. People can build more in the
buildable areas. Ms. Louisos added that there is also civic space that is not lawn. It is usable
open space.
Mr. Von Turkovich said he is very interested in building typology. He tends to be drawn to the
“stacked flat” building of 3-5 stories. He asked if you can build a 2-story building of that type.
Mr. Conner said possibly. Typically, it would be located in the higher density area or in a
transition area. He will bring that idea to the consultant. Mr. Von Turkovich said it is a very
efficient building design. He noted that 3 story buildings become expensive because of
elevators. He asked whether the DRB would be allowed to modify a building type and noted
the need to make room for “evolution.”
Ms. Louisos said that each PUD would have to have multiple building types. In a TND, there
would be a more traditional neighborhood feel. Buildings would like more like single family
homes. Mr. Gagnon added that there will be percentages of each required building type, and
the Commission is still working on those percentages.
5
Mr. Conner said in the current draft, with 10 acres, a developer would select a minimum of 3
building types and a percentage of each, with no more than 50% of any one type. Developers
would have the flexibility to do something that will fit well in a neighborhood context. Ms.
Ostby said that where they are being proscriptive is with the need to have a cohesive
neighborhood with flexibility in design. Mr. Conner said the rules say very little about
architectural style other than having a building present a front door to the street or to a center
green.
Ms. Ostby said that South Village and the new O’Brien development are following a lot of what
the new PUDs will have. She also noted that Mr. Von Turkovich’s new development does this
as well. Mr. Conner added that the Kirby Cottages are a good example of what a cottage block
could look like.
Ms. Ostby said the 1.2 units per acre has never been an average in a specific development. It is
an average for the whole SEQ.
Mr. Riehle was concerned with having 90% multiplexes (e.g., 40% duplex and 50% higher
multiplexes) with only 5% single family. Mr. Conner said it may be appropriate to put a cap on
the multiplexes in a neighborhood. He noted that in the Rye development, there are 12
“cottages,” 12 4-plexes, and 27 single family homes. Mr. Riehle said the neighborhoods cited
are lovely. He is just concerned with the potential.
Ms. Louisos noted that some housing types are very similar. The proposal is for a minimum of
15% of a type and a maximum of 50%. She suggested that possibly the sum of multiplexes
should be 50%. Mr. Conner added that they may want to lump town homes and multiplexes.
Mr. Gagnon agreed with capping multiplexes with possibly a higher cap in the Transit Overlay
District, lower elsewhere. Ms. Ostby asked if a development commits to a “tighter”
neighborhood, could there be flexibility for 2 types, duplex and single family. Ms. Louisos
suggested that another type could be a small house on a small lot. Mr. Conner showed photos
of what “small lots” look like in South Burlington including City Center, Village at Dorset Park,
Kirby Cottages, and also 5 Sisters in Burlington. He also noted there is a range of building types
and sizes in Queen City Park, Blackberry Lane (off IDX Drive) and South Village. Southpoint has
small single family homes.
Mr. Conner then asked if members wanted to “play around” with allocations. Mr. Gagnon said
he wanted caps, with higher caps in the Transit Overlay District. Ms. Ostby suggested
decreasing the minimum lot size from 5000 sq. ft. to 3800 sq. ft. Mr. Conner asked to let staff
toy with that idea and possibly suggest an additional building style.
6
A straw poll of members indicated a positive response to caps.
Ms. Louisos noted that the minimum for civic space is now 10%, but 15% has been suggested.
Mr. Conner said that is achievable, especially with smaller lots.
Members gave a thumbs up to 15%.
Ms. Ostby asked if there should be an allowance for a larger house. Mr. Conner said they
shouldn’t go beyond 10,000 sq. ft. because then you lose the neighborhood feel. He added that
there could be a “peculiar parcel” where there is some flexibility.
Mr. Riehle asked if the intent is to preclude houses such as those at Butler Farms. Mr. Conner
said generally yes, in the sense that the lots are somewhat larger and there are no focus points
to the neighborhood, but you can still get a large house on 10,000 sq. ft.
Ms. Ostby asked about accessory apartments. Mr. Conner said that State law allows a single
family home to have an accessory apartment in the same or an appurtenant building. In an
adjacent building, you must meet the required setbacks, etc.
Ms. Dooley applauded the inclusion of smaller houses, especially from an energy point of view.
Mr. Conner then addressed how commercial uses fit into the TND. He said there are a few
options. There could be a community building for use by the neighborhood. There could also
be some authorized non-residential uses such as small retail, restaurant, personal instruction,
but it would be capped at 5000 sq. ft. per use. There could also be a vertical mixed use with a
store and apartments above it.
Ms. Ostby said she has heard people ask to allow for childcare. Mr. Conner said staff was 100%
supportive of that, and indicated he thought it was in the current draft but would confirm.
Members gave a thumbs up for childcare inclusion.
Mr. Gagnon said that in addition to a square foot limitation, there should be a standard that the
commercial building matches the architecture of the neighborhood. Mr. Conner said there are
guidelines for that and they have worked fairly well.
Ms. Dooley noted there are some uses protected by the State including a group home for no
more than 6 people with developmental disabilities. Registered child care can go up to 6 full-
time in-home.
Ms. Louisos also noted accommodations for home businesses and people working from home.
7
5. Review/possible action on possible updated meeting participation guidelines:
Ms. Louisos showed the list of proposed guidelines for public participation.
Mr. Mittag moved to approve the guidelines for public participation and Commissioner
guidelines as shown. Mr. Gagnon seconded. Motion passed unanimously.
Ms. Ostby asked about the procedure to get something on an agenda. Ms. Louisos said to ask
her or Mr. Conner. There can also be a short discussion under “other business” about adding
something to a future agenda. Mr. Conner said the “other business” discussion would not
violate the open meeting law. He also noted there is some authority for the Chair to delay
addressing an item if it interrupts another discussion.
6. Other Business:
Mr. Conner reminded member that their next meeting is 10 March, 7 p.m. The next night is the
joint meeting regarding the I-89 corridor study at 5 p.m.
As there was no further business to come before the Commission, the meeting was adjourned
by common consent at 9:05 p.m.

SOUTH BURLINGTON PLANNING COMMISSION
MEETING MINUTES
3 MARCH 2021
1
The South Burlington Planning Commission held a regular meeting on Tuesday, 9 March 2021,
at 7:00 p.m., via Go to Meeting remote technology.
MEMBERS PRESENT: J. Louisos, Chair; B. Gagnon, T. Riehle, M. Ostby, M. Mittag, D. Macdonald,
P. Engels
ALSO PRESENT: P. Conner, Director of Planning and Zoning; A. Bolduc, City Attorney; R. Gonda,
M. Cota, V. Bolduc, I Genzhiyev, A. & A. Chalnick, S. Dooley, S. Dopp, R. Greco, J. Bellavance, S.
Partilo, A. Jensen-Vargas, D. Peters, L. Yankowski, R. Brinkerhoff, C. Trombly, D. Seff, D.
Crawford, B. Sirvis, J. Simson
1. Agenda: Additions, deletions or changes in order of agenda items:
No changes were made to the agenda.
2. Open to the public for items not related to the Agenda:
Mr. Cota introduced himself as the new City Council member and invited Commission members
to reach out to him at any time. Ms. Louisos commented that it is good to have another City
Council member with a DRB background.
3. Planning Commissioner announcements and staff report:
Ms. Ostby noted that the renovation of the People’s Bank building will result in half of the
building becoming residential. She thanked Mr. Conner for spending time to explain how TDRs
would work with building types. She also noted that she held another phone information
session regarding the “calculator” concept.
Ms. Louisos said she spoke with the City Council Chair and they will look to schedule a joint
session with the Council in the next few weeks regarding the “calculator”, planned unit
developments, and other work under Interim Zoning.
4. Commission reflections on Open Meeting guidance: Q & A. with City Attorney Andrew
Bolduc:
Ms. Louisos advised that Commission members had watched a video on the Open Meeting Law
before this meeting.
2
Mr. Mittag asked if it is a requirement that all documentation that is to be discussed is available
to the public before a meeting. City Attorney Bolduc said yes it should be but is not “fatal” to
the meeting warning if it isn’t as long as the public has a chance to see it and respond to it. This
is a Constitutional requirement. The Commission is at all times accountable to the public.
Mr. Riehle asked about reaching out to other Commission members to get feedback from them.
Mr. Bolduc said that is a “chain meeting” and should be avoided.
Mr. Gagnon asked about email and sending something of interest to other members. “Reply
all” is a violation. Mr. Bolduc said that just distributing information is OK. A member can ask
“should we address this at a future meeting?”, and that can be discussed over email as it is only
about what will be on the agenda.
Ms. Louisos asked whether they are still OK with virtual meetings and whether there will be a
time limit. Mr. Bolduc said that for the time being, all virtual meetings are OK. He would advise
if that changes. He did not that there is a move in the Legislature to make that a permanent
option. Mr. Conner noted that if the Legislature doesn’t extend the time limit, there can be a
“hybrid” option in which at least one Commission member would need to be physically present
at the “live” meeting site.
Mr. Conner asked whether any other requirements have been made by the Legislature other
than those which are pandemic-related. Mr. Bolduc said the Legislature hasn’t changed
anything regarding social media at this time. The Vermont League of Cities and Towns and the
Secretary of State’s office have pamphlets and guidance on the Open Meeting Law. Both talk
about social media and conversations between members. He cautioned members to be very
careful about commenting. Ms. Louisos said members should be careful about posting
anything and to make it clear you are speaking as an individual, not as a Planning Commission
member. Mr. Bolduc added that this applies on the staff level as well. He further cautioned
members to know what “hat” they are wearing and whom they are addressing.
Mr. Conner said that in his 12 years with the city he is most proud of how the community takes
these things seriously. He felt it reflects well on the community.
5. Continued Land Development Regulations Work Session:
a. Review overall Project Schedule and discuss possibility of advancing
Environmental Standards (Articles 10 & 12 and related amendments) in advance of
others:
Mr. Conner said that although a lot of things are intertwined, he was comfortable with
advancing Articles 10 and 12 along with some definition updates, etc. These Articles were
3
designed to stand along and are fairly self-contained. Some subdivision standards support
Articles 10 and 12 but don’t rely on them. Taylor still has a few questions for the Commission,
and these could be warned in the next couple of meetings.
Ms. Ostby said it seems the Commission will want the opportunity to do a last connection of
Articles 10 and 12 with the PUDs. This could result in a conversation regarding density. She
was concerned with releasing 10 & 12 too soon.
Mr. Gagnon felt that if the PUDs are just 2 or 3 weeks behind, he would like to keep everything
together. Mr. Conner said he expects the last pages of the PUDs later this month. There is still
a discussion to be had as to how the pieces worth together. He noted a potential gap in April
(re: impending parenthood) when the Commission can have some discussion of things on the
“to do” list without him being present. All in all, he felt the PUDs were likely a few moths
behind rather than a few weeks.
Mr. Riehle said it gets confusing to go from one topic to another. He felt the process shouldn’t
have taken so long.
Mr. Mittag said that as they have moved to Article 15, it has become more complex with
unintended consequences from the impact of the regulations. And some things haven’t been
touched on yet. He felt everything is intertwined. He added that he’d never looked at Chapter
9 until a few days ago and didn’t know that was connected to Article 12. He felt they should
complete Article 12 and then look at that.
Mr. Macdonald agreed with Mr. Riehle and Mr. Mittag and felt he didn’t have a full wrap-up on
Article 12.
Mr. Conner reminded members that if they adopt something, it can be changed. He didn’t
recommend doing that too often, but regulations can always be adjusted. Mr. Mittag noted
there will likely be changes after the public hearing. He favored focusing on one thing at a time.
Ms. Ostby said the benefit of the City Council getting Articles 10 and 12 is that they may have to
make a decision about certain parcels and may have some other open space conversations.
Ms. Greco said it is easier to absorb one article at a time. She added that if the Commission is
having a hard time grasping things, imagine the public.
Ms. Dooley was concerned about how much time is left in Interim Zoning and was worried
about having separate processes as each can have more or less time. She felt the Commission
had a head of steam on the PUDs. She didn’t see separating things as a time-saver.
4
Mr. Gonda said he has tried to follow the progress of the proposals but has found it confusing.
He noted that Mr. Conner gave 2 updates to the Natural Resources Committee, and they are
also befuddled. Concerns include: not seeing that the Open Space Report was taken into
account, and the focus on “acreage” as opposed to “quality” when considering protections.
Ms. Louisos felt there would be more productive public comment if the Commission were more
focused.
Mr. Mittag said he has a lot of questions to get clarified. He didn’t feel there had been a
decision as to whether some of his recommendations were accepted or not. He also said there
are things in Mr. Conner’s memo that he hadn’t thought about. Mr. Conner suggested having a
“straw poll” on recommendations so there is a record of the Commission’s decisions.
Mr. Gagnon then moved to proceed with completing Articles 10 and 12 and related items in
order to advance them to public hearing and to the City Council as a first priority. Mr.
Macdonald seconded. Motion passed unanimously.
Mr. Gagnon said it would be good to have a final mark-up before warning for public hearing.
Mr. Conner said the next step will be as clean a draft as possible. Mr. Gagnon said he would
like to see a clean version without “bubbles.” Mr. Conner said the Commission can make any
changes after the public hearing, as long as they are not things the Commission has never
discussed.
Ms. Greco asked if the public will get a clean version before the public hearing. Mr. Conner said
the public hearing will be warned 15 days in advance, and the document must be available to
the public.
Ms. Louisos reminded members of the possible joint work session with the Council. She
suggested this take place after a clean version is released but before the public hearing. Mr.
Conner noted that the Commission would not have to warn a second public hearing if they
make changes after its public hearing. If the City Council makes changes after their public
hearing, they must warn a new public hearing.
Mr. Engels said it would be good to have a document accompany what is sent to the City
Council to explain what is being sent and to include pictures. Mr. Conner said there is a 2-page
document that described things. He will consider pictures.
Mr. Mittag said the deletion of Article 9 will have a big impact on Article 12. He felt stated
there is more work to be done than they think.
5
b. Continue discussion of options for how to integrate Inclusionary Zoning where
currently applicable into PUDs; consider possible expansion/replacement of
current affordable housing density bonus structure:
Mr. Riehle asked if there is an option to donate land in lieu of inclusionary units. Mr. Conner
said there is. Then if the city has land available for housing, developers could be solicited to
develop it without having to consider the cost of the land. This has not yet been done.
Ms. Louisos said she was comfortable with what is in Mr. Conner’s memo. It doesn’t feel like
they would be layering density on density.
Mr. Macdonald expressed concern about incentives and the statement that incentives could
alter the planned character of a PUD. Mr. Conner said incentives can be part of the regulations.
He cited how this works in City Center. This satisfies both the State statute and the intent of
the statute.
Mr. Mittag asked if he is required to build 16 inclusionary units and builds 3-bedroom units,
does he have to build only 8. Mr. Conner said yes but with “an asterisk.” The justification is
that this provides family housing. Mr. Mittag felt it was counterintuitive as the city wants as
many units as it can get. Mr. Conner said housing studies identify affordably family housing as a
big gap. He noted the popularity of 4-bedroom units on Market St. Mr. Ostby added that the
new O’Brien development has 3-bedroom homes as inclusionary, and they will be perpetually
available to families.
Ms. Dooley corrected the above statement and noted that three 3-bedroom inclusionary units
count as 2 inclusionary units.
Mr. Riehle asked what happens with TDRs in the Southeast Quadrant (SEQ). Mr. Conner said
that today affordable units don’t have to buy TDRs. That could be continued as an incentive.
Mr. Riehle asked what then happens to TDRs. Mr. Conner said this would only apply to the
affordable units. You could still use TDRs in the rest of the SEQ. There is also thought of
expanding TDRs throughout the whole city. Mr. Gagnon said that at this point he would
support TDRs in the whole city.
Mr. Conner said it would be helpful to have Commission guidance as soon as the Commission is
comfortable with that. Inclusionary requirements need to be incorporated the sooner the
better.
Mr. Macdonald asked if inclusionary units would be dispersed among building types. Mr.
Conner said they need to be thoroughly integrated into the neighborhood but can be in one
6
building type. They cannot all be in one 20 unit building if there is only one such building. They
also need to have the same average number of bedrooms as the rest of the development.
Mr. Mittag said he wasn’t ready for city-wide inclusionary zoning until he knew the impact on
the SEQ. He felt it was a big change to go from voluntary to mandatory.
Ms. Louisos stressed that density is not being increased with inclusionary zoning, and the city is
not giving up anything. There is no reason not to consider expanding it further. Mr. Mittag felt
that combined with PUDs it could make a huge difference. Ms. Ostby said that today the only
way to get affordable housing is to tie it to a density bonus. With inclusionary zoning,
affordable units are tied into the underlying density. Mr. Conner said that is correct. Under
State law, there must be an “incentive,” but that does not necessarily have to be a bonus. Mr.
Conner noted that where inclusionary zoning exists in City Center, it does not increase density.
Mr. Gagnon moved to direct staff to move ahead with exploring “a” and “b” on staff’s
memorandum to have something ready for when work on Articles 10 and 12 is complete. Ms.
Ostby seconded.
Members discussed the option to remove “increase base density” from the list of incentives.
Mr. Conner said he would ask the City Attorney about that. No one element must be in there,
and he comfortable there is a good slate of options. The Court might say the city is not meeting
the standard. Mr. Conner also noted that the consultant may have other ideas. Mr. Mittag said
a property owner might not want to increase the base density. Ms. Ostby was comfortable
with removing that option, if possible.
In the vote that followed, the motion passed unanimously.
c. Consider proposal from Commissioner Ostby to consider a basic vs. expanded
Conservation PUD:
Ms. Ostby said she was concerned with people who have 50% of their acreage in hazards or
level 1 resources in the SEQ. The focus was to be on those parcels being most impacted. She
was concerned with expanding it to take out buildable land so that it would never be
developed. She said some people would say they shouldn’t conserve anything permanently
because the world changes.
Mr. Mittag said that once something is on the books, it’s hard to get rid of it. He felt they need
every square inch of meadow, etc. from a climate mitigation point of view. He wouldn’t
support Ms. Ostby’s idea.
7
Ms. Louisos said this would be a great conversation when they have the Conservation PUD
language in front of them.
Mr. Chalnick felt a landowner should have the option to conserve land.
d. Overview of related amendments to PUD/Subdivision/Environmental Protection
standards updates; Commission prioritization:
Mr. Conner asked members to review the memo and think about which subject areas they want
to delve deeper into. There are some site plan amendments (e.g., many towns give
modification authority to the DRB, especially regarding dimensions). Mr. Conner noted that
much of Article 9 (SEQ) is based today on how a PUD should be arranged. If you adopt the TND
form of PUD, very little remains in Article 9. What does remain is how TDRs and environment
protection work. He has heard that some of the SEQ design elements should be city-wide. Mr.
Mittag didn’t see how they could delete such an important part of the LDRs unless those
protections are transferred to Article 12. Ms. Louisos suggested putting this on a future
agenda.
Mr. Conner noted the SEQ is almost self-contained. His suggestion would to place rules where
they are logically found. The Commission wanted Article 12 to address natural resources in the
city.
Ms. Ostby said she couldn’t find the portion of the minutes where there was a recommended
change from Industrial-Open Space zoning to Mixed Use. She felt they would need to discuss
the Official City Map and in particular Swift Street Extension. Mr. Conner said the area referred
to in the memo is immediately south of the Interstate. Article 12 standards on that property
would have the western portion in a forest block.
Ms. Dopp questioned potential development in the NRP. Mr. Conner said that as drafted
nothing about the amount of development is proposed to change in the NRP. There might be a
slight modification to the building envelope.
Mr. Riehle asked when they would get to the items on Mr. Conner’s memo. Ms. Louisos said
these will be addressed when they get into PUDs more. Some items are updates; some are new
items. Mr. Conner said they are most closely related to PUDs, though some (e.g., changes in
State rules regarding subsidiary dwellings) are not.
6. Provide direction on selection of name for new street adjacent to Library/City Hall:
Ms. Ostby suggested going to the Marcotte School students for ideas. Members liked that idea.
8
Ms. Dooley spoke to the issue to naming streets for individuals to erase prior racial injustice.
She cited Lavinia Bright, the first woman of color to serve in the Vermont Legislature was from
South Burlington. Ms. Dopp noted the possibility of former Librarians.
Members agreed to go to the Marcotte students with two topic areas: names that are
complementary to Garden Street & Market Street, and names for people of historical
significance to South Burlington.
7. Meeting Minutes of 23 February 2021:
Mr. Gagnon moved to approve the Minutes of 23 February 2021 as written. Mr. Riehle
seconded. Motion passed unanimously.
8. Other Business:
Mr. Conner reminded members of tomorrow’s I-89 study meeting to provide feedback to
CCRPC on evaluation criteria. He encouraged members to attend.
As there was no further business to come before the Commission, the meeting was adjourned
by common consent at 9:22 p.m.

SOUTH BURLINGTON PLANNING COMMISSION
I-89 BREAKOUT SESSION MEETING MINUTES
10 MARCH 2021
1
A quorum of the South Burlington Planning Commission participated in a Joint Meeting/Working Session
regarding the I-89 Corridor Study facilitated by the Chittenden County Regional Planning Commission on
Wednesday, 10 March 2021, at 5:00 p.m. via Zoom remote technology. Minutes for the joint meeting
are with the City Council minutes. The Planning Commission held a “break-out” sessions afterwards with
the same Zoom remote technology.
Present: Eleni Churchill, Paul Conner, Jessica Louisos, Duncan Macdonald, Michael Mittag, Monica
Ostby, Charlie Baker (attended part of the meeting)
1. Breakout room to have individualized conversations and feedback regarding I-89 Corridor
Study Interchange Evaluation Criteria
Mr. Mittag stated concern regarding impact to wetlands, particularly at the 12B location. Requested
wetland impact metrics be included. He has walked the area and cannot see how the proposed location
of 12B can avoid the destruction of this wetland. Ms. Churchill stated that there is a wetland metric and
an updated 12B concept seemed to address wetland issues but will review.
Ms. Louisos requests economic access impact as the interchanges connect to areas of growth. She
would like to see a sub set metric of how each exchange contributes and/or detracts from supporting SB
City Center. Ms. Churchill indicated that she will discuss this with the consultant team.
Mr. Mittag suggested underlying assumptions might not have taken into account that we expect more
people to work from home This would mean fewer commutes and fewer cars on the road. Also, a lack of
transit for rural residents might lead to the use of robotaxis by rural residents making traditional transit
less important. might expect more working from home thus taken into account. Also a lack of transit for
rural residents. Ms. Churchill explained that due to the uncertainty of how people will travel in a post-
pandemic world, the study will recommend monitoring travel patterns and develop triggers to identify
when major roadway capacity improvements are needed so they can move forward.
Ms. Ostby stated disappointment that a version of exit 14 with the inclusion or assumption of a separate
bike/ped bridge to it's south was not presented. Ms. Churchill explained that the isolated bike/ped
bridge is being reviewed as part of the I-89 corridor "bundle" and evaluated separately (in the next
phase of the study). That it might be a mid-way project that is constructed prior to an exit 14
reconstruction. And that any exit 14 option should include safest bike/ped facilities even if a separate
bridge is constructed.
Ms. Ostby also asked if truck/commercial traffic impact not only on each exit but the surrounding city
roads be considered. Are there areas of SB that would see a rise in commercial traffic? Ms. Churchill
indicated that the regional model provides data on overall vehicle traffic but not necessarily on
commercial traffic. The project team already developed maps indicating change in volumes for each of
the five interchange concepts. Note: The maps are available on the project website
(www.envision89.com) and were shared with the City Council Feb 16, 2021.
Regarding exit 13, Ms. Ostby stated safety concerns of heavy truck/commercial on a 4 lane boulevard
design connecting I-89 to Shelburne Road. She also asked if the land connected to the southern portion
of the current 189 might be converted to bike/ped use. Ms. Churchill explained that since it is Federal
land it would have to be invested. They will review how to identify commercial traffic safety impact.
Mr. Conner suggested that all exits review what Federal lands would be no longer needed with the new
designs and what might happen to that land. That even if the land ownership continued to be Federal
2
and was left alone, what impact would it have on a potential quality of life improvement. He suggested
adding a metric of "Return of Valuable Land." Ms. Churchill stated that such questions will be directed
to the Vermont Agency of Transportation and Federal Highway Administration.
Mr. Mittag asked about the cost impact of creating 12B, how many acres would have to be purchased as
is this part of the cost estimate. Churchill confirmed the construction estimates do not include ROW or
land acquisition expense.
Mr. Mittag supported exit 13 given its direct access to the airport, reducing traffic load to exit 14, and
asked that this be considered in a weighted evaluation.
Mr. Macdonald asked for clarification of the process. Ms. Churchill explained that while the final
decisions on which interchange concepts to move forward for further evaluation are made by the I-89
Advisory Committee, they will give preference to the direction received by the City Council. As part of
the process the committee will look at midway options such as bike/ped bridge before final interchange
work. That major interchange improvements (permitting, design and construction could take 15 to 20
years. Mr. Macdonald suggested that timing to completion is an important metric that should be
included.
Mr. Macdonald asked for clarification regarding the two future roads shown on the 12B draft,
connecting Tilley Drive to Kimball Ave and to Community Drive.. Mr. Conner confirmed both roads are
currently on the Official Map, and one, connecting to Kimball Ave, has its northern half currently under
consideration as part of a proposed development.
Ms. Louisos reminded that there was a suggestion to consider how the scoring might be weighted. This
is a topic the full PC will discuss in an upcoming meeting. Further, should any goals be weighted? Ms.
Churchill also ask the committee to review the scoring methodology and offer any comments.
Mittag asked how to best engage the community. Churchill reviewed the public sessions already held,
and future sessions planned including 3/18 and mid April.
Ms. Ostby stated that while reviewing exits 14 and 13 can be clear and constructive, evaluating whether
to support a new 12B will be highly political, making it more challenging to be objective. Mr. Macdonald
stated reviewing a new construction at exit 12B partial vs a partial reconstruction (such as 14 and 13)
would be a much heavier left.
Ms. Ostby asked if a metric considering the benefit of each interchange to the surrounding cities can be
useful. Mr. Baker stated that earlier research confirms that 12B is not more helpful to Hinesburg
residents' access to 89 than using the current 12. Considering the fuller option for exit 13 might review
benefits to supporting Burlington.
Mr. Baker asked that the PC further contemplate if something more can be weighted, and if any
considerations are missing. He also mentioned as an example that in the City Council sub group this
evening safety was seen as a higher concern than cost.
The meeting was adjourned by common consent at 7:09 p.m.

SOUTH BURLINGTON PLANNING COMMISSION
MEETING MINUTES
16 MARCH 2021
1
The South Burlington Planning Commission held a special meeting on Tuesday, 16 March 2021, at 7:00
p.m., via Go to Meeting remote technology.
MEMBERS PRESENT: J. Louisos, Chair; B. Gagnon, T. Riehle, M. Ostby, M. Mittag, D. Macdonald, P.
Engels
ALSO PRESENT: P. Conner, Director of Planning and Zoning; S. Dooley, J. Bellavance, A. Jensen-Vargas, A.
& A. Chalnick, R. Greco, S. Dopp, N. Hyman
1. Agenda: Additions, deletions or changes in order of agenda items:
No changes were made to the agenda.
2. Open to the public for items not related to the Agenda:
No issues were raised.
3. Planning Commissioner announcements and staff report:
Ms. Ostby advised she had attended last night’s City Council meeting at which Interim Zoning was
discussed. She felt it was clear the Council is waiting to hear from the Commission, but she felt there
were things the City Council could be doing independently which they are not doing and which would be
very helpful to the Commission.
Mr. Riehle noted there are 224 units in the DRB hopper pending or about to go through. He asked how
many units there are in the city now. Mr. Conner estimated 9000. Mr. Riehle said “growth is
happening.” Mr. Mittag said there are also projects being built now.
Mr. Conner: On Thursday evening there will be a public meeting regarding the CCRPC I-89 study.
Next Tuesday, there will be a presentation to the Planning Commission by the Swift/Spear Street
Study Group. Materials will be provided in advance.
Mr. Conner said he testified at the Senate Transportation Committee last week regarding a bill
to formalize the definitions of electric bikes and what level of control municipalities would to have (e.g.,
use on rec paths).
4. Commission discuss and prepare feedback on I-89 Corridor Study Interchange Evaluation
Criteria:
Ms. Louisos noted that feedback needs to go to the CCRPC by next Monday.
2
Mr. Riehle said what comes to mind is a “Pandora’s box” regarding Exit 12B which would connect to
Tilley Drive and Swift Street over wetlands in both cases as well as other issues. Mr. Mittag said when
he brought up the wetland issue, he was told it is not a problem, but when he walked the area he could
not see how it can be avoided.
Ms. Louisos said she had mentioned that there were no metrics specific to South Burlington. She felt it
would be good to know how the options contribute to/detract from City Center.
Mr. Riehle said safety re: bike/ped is still his concern and which option is best for that. None seem to
him to be good. 14 and 12B seem the most difficult regarding those safety concerns.
Mr. Engels thought 13B was a good idea: no cloverleaf with still an on/off to I-89. He also felt the city
should have a direct say since all the interchanges are in South Burlington.
Mr. Conner reminded members that the reason for the input is the evaluation criteria, to put data
behind why one option is selected over another.
Mr. Macdonald said he would be OK with 12B, but he didn’t think it will happen. He was OK with 13 but
not either option. He felt it is better to do something where there is a “start.” 13 also puts people
closer to City Center and on a 4-lane road direct to the Airport.
Ms. Louisos said a partial interchange is more feasible from a time-line point of view. Mr. MacDonald
questioned whether that is the case. Mr. Conner said that is the interesting question. Pare of the metric
is when bridges need to be upgraded/replaced. He felt Exit 13 is probably more of a project that the
one over Williston Road. There is also the issue of on-going appeals.
Ms. Ostby said there was talk of a time-line and they were told “new” would take longer. She noted all
of this is 15 years out and timing should be considered. She also hoped CCRPC can work out the
commercial vs. residential traffic issue. She was concerned with converting I-189 to a boulevard
because of the high volume of truck traffic.
Mr. Conner noted that some options give land back for natural resources, etc. There may be a way to
evaluate the amount of truck traffic that is brought closer to or further from homes and what that
means for quality of life.
Mr. Mittag asked if they will have the opportunity recommend sequencing. He felt 13 would give the
city the biggest bang for the buck and it solves some traffic problems. Mr. Conner said there is already
some prioritization, doing things that preclude the need for any of the major options.
Ms. Dopp said that some time ago she heard a CCRPC person say one of the 3 options would be dropped
out. Mr. Conner said the objective is to have options at each intersection, one at 14 and one at 12/13.
Ms. Dooley noted that the prospect of appeals was a major factor in the abandonment of the Circ
Highway.
3
Ms. Greco felt the CCRPC should focus on non-car options. She felt there is time to mull this over. She
noted this was talked about 10 years ago at a meeting.
Ms. Dooley said there are now 6 goals and a plan to weigh them all equally. She also noted that Mr.
Baker said safety should come first. Ms. Dooley questioned “whose safety?”. Mr. Conner said safety for
all users. He heard that one of the Exit 13 options is less safe with the U-turn, though it is much less
expensive. Ms. Ostby said a U-turn is so unexpected that people will get “lost” and frustrated and then
hurt. People expect an off-ramp. She felt it is what provides the most predictable path for drivers. Ms.
Louios felt “familiar design” is a good way to phrase that.
Mr. Mittag noted he has asked whether the metrics of loading could change because of people working
from home. Ms. Louisos said travel may be less “carcentric” 30 years out. Ms. Ostby noted the trend to
autonomous truck traffic and the potential to see more commercial than “people” traffic. Mr. Mittag
noted the possibility of seeing drones for deliveries in the future.
Members were OK with Ms. Louisos and staff compiling comments for CCRPC. These will be circulated
to members.
Mr. Riehle asked when the vote will be. Mr. Conner said the CCRPC will attend the meeting on the 29th.
He will check in regarding the timeline. Ms. Louisos said it looks like an April to June timeframe. Mr.
Mittag asked whether they should do a “ranked” choice of the goals. Ms. Louisos suggested members
who want to do that should send their rankings to her.
Mr. Chalnick felt the differences in the options were so small.
Ms. Ostby said that Charlie Baker had said 12B doesn’t benefit Hinesburg and that the existing Exit 12 is
better. She asked if benefit to other towns should be a consideration.
Mr. Engels then moved to authorize Ms. Louisos to submit a letter to CCRPC with the Commission’s
comments. Mr. Mittag seconded. Motion passed unanimously.
5. Continued Land Development Regulations Work Session:
a. Review updated Environmental Protection Standards following Commission guidance and
related amendments:
Ms. Louisos said she had a discussion with the Council Chair about the timeline and how helpful it would
be than when a Commission public hearing is warned there can be a joint meeting with the Council that
would include a deeper view of the PUD work as well. The first week in April was talked about for an
update, then warning the public hearing. Ms. Louisos added that in the next few meetings she would
like to get a draft out for public comment.
4
Ms. Ostby said that while the Commission agreed to focus on Articles 10 and 12, they didn’t agree on a
separate public hearing for 10 and 12. Ms. Louisos said that would be a good topic to discuss at a joint
meeting with the Council. Mr. Gagnon said 10 and 12 could still go to the Council and they could hold
onto it until they get the PUD stuff.
Ms. Louisos stressed that the Commission should focus on policy rather than “nitty gritty” word choices,
etc.
Members then reviewed specific areas as follows:
Definitions: It was noted that there are places where there is reference to “forest blocks” instead of
“habitat blocks.” Ms. Ostby felt the “historic site” should be defined. Ms. Louisos said “core habitat”
may also need to be defined as it is referred to later on.
Description of Districts: Ms. Louisos noted that an old city map had been referred to. Now there is
specific information as to what to use. Ms. Ostby said they should indicate what the new Natural
Resources Map is replacing. Mr. Conner suggested that be done via a memo. Regulations are the
regulations in effect. Mr. Mittag said that where “undue adverse affects” is used, reference to the test
(304h) should be made. Mr. Conner said he will see how to draft that some way. Mr. Engels asked
whether “building envelope” is the building or the lot. Mr. Conner said that as used here it is the are of
the lot allowed to be built within.
Article 9 Items: Mr. Mittag felt that environmental protections in the Southeast Quadrant (SEQ) are
being removed and they shouldn’t be offering less than what was there before. He felt the old language
regarding prime ag soils, grasslands and shrub lands should be included as Level 2 resources. Ms.
Louisos said that Articles 10 and 12 would be applicable across all districts. Mr. Engels said he read the
Interim Zoning Ordinance and it seems to be a “open space ordinance.” He felt they should be looking
to improve open space. He felt it was the Commission’s work to turn the work of the Open Space
Committee in LDRs. Ms. Louisos said the Committee evaluated individual properties, and the
Commission felt it was more important to indicate under what criteria things would be protected.
Mr. Gagnon said the Commission has taken data from a number of sources and have written regulations
to be more protective of natural resources (e.g., streams and wetland buffers). For the City Council, the
Commission is to provide the regulatory piece. Regarding open space, Mr. Gagnon noted there are
other tools available (e.g., purchase), and what is needed are underlying regulations for the land to be
used and to strike a balance. If an owner wants to conserve or to sell land for development, there
should be a mechanism to do both. Mr. Gagnon also noted that the Comprehensive Plan had many
goals, some of which conflict with each other: open space vs. affordable housing. The Commission is
trying to strike a balance and has written regulations leaning toward protecting resources but not to the
exclusion of everything else.
Ms. Louisos said that maps 7 & 8 were incorporated into the Comprehensive Plan as a guide for studies
and goals which could eventually be part of the LDRs, part of a purchasing plan for the city, etc. She
didn’t think anyone ha the sense that maps 7 & 8 were to be regulatory, and they didn’t put a lot of
5
thought into what was on those maps. Articles 10 and 12 are vetting that now. Ms. Louisos noted that
the group that compiled those maps did not have consensus. She added that unfortunately those 2
maps replaced map #6 which was referenced in Article 9. She said map 7 shouldn’t have been
regulatory in the first place, and the Commission is now being very specific about what is being
regulatory. Ms. Louisos also felt the Natural Resources Committee can work on finding specific
grasslands to protect. She stressed that the Commission has protected river resources, added the 500-
year flood plain, and done work on habitat blocks and connectors.
Mr. Mittag said the Commission never discussed dispensing with Chapter 9. It just happened. It is the
current regulation that people have relied on, and he felt it would be “highhanded” to dispense with it.
He felt that would result in less environmental protection than now.
Mr. Gagnon disagreed that things are being given up. He said he personally wouldn’t regulate
grasslands. Ms. Ostby said when she looks at the riparian on Map 7 and what the Commission is
protecting, everything is covered and the Commission added to it. She also noted that people can
petition the Commission to reconsider other things.
Mr. Engels noted that what is redlined out in 906B3 is what the DRB used to rule in favor of the
neighbors re: Dorset Meadows.
Mr. Mittag acknowledged that riparian is covered, but he still felt agriculture, meadowlands and scrub
lands are important.
Mr. Macdonald said the Commission had a robust discussion as to what was to be protected in hazards,
level 1 and level 2. He agreed not to rewrite Article 9. Ms. Louisos added there is no comprehensive
mapping of grasslands, and the maps in the Comprehensive Plan were not vetted for LDRs.
Ms. Ostby said the Commission “put a stake in the ground” and it is up to the City Council to give a
different directive.
Mr. Gagnon noted that the definition of agricultural soils covered everything in the city, so the
Commission had decided not to use it. He felt the Commission can agree to disagree. Mr. Riehle agreed
they should vote and move on.
Mr. Mittag cited a difference between “primary” and “prime ag” soils and noted the latter is more
restrictive. Primary soils are everywhere. Prime ag are very limited. Ms. Dopp said “prime ag” is a very
specific term. She also noted the IZ Committee commented that open space recommendations should
be reflected in the LDRs. She suggested reviewing the Committee’s criteria to make their judgments.
Ms. Ostby said that is what the Arrowwood Report did, and the habitat blocks are in those parcels.
Mr. Chalnick asked about the history of preserving lands in the SEQ. Mr. Conner showed the 2006 plan
map and noted there were 3 primary “natural communities”: the Great Swamp, the Cheese Factory
Road Swamp and Van Sicklen Avenue areas. He noted that the references in the Comprehensive Plan
can’t be from this source and must be from the 2016 map. Mr. Conner then showed the 2016 map #7
6
and the draft map in this meeting’s packet. He identified various elements in each (e.g., wetlands and
buffers, 500-year flood plain). He also indicated in the new map features such as habitat blocks, river
corridors, steep slopes, etc. Ms. Ostby said from what she saw, nothing from map #7 isn’t covered by
more in the current map. She felt great looking at the 2 maps.
Mr. Conner then showed map #8 which identifies primary ag soils, 500-year flood plain, Great Swamp as
identified by the State, including different types of forests, and “uncommon species.”
Ms. Ostby then moved to accept the resources currently listed in Articles 10 and 12 to put forward in
the draft for public comment. Mr. Gagnon seconded. The motion passed 4-3 with Messrs. Mittag,
Engels and Riehle voting against.
Mr. Mittag then moved that rather than accept the changes in Chapter 9.06 that the protections
offered in the current regulations, namely prime agriculture soils, grasslands and shrublands be
included in the protections in Article 12 under hazards, level 1 or level 2, and not to abandon those
protections. Mr. Engels seconded.
Ms. Louisos said she didn’t see this as the only way to cover those things, and she didn’t think a whole
new section was needed.
Ms. Greco asked if there are more or less areas protected. Ms. Louisos said some areas are bigger, and
there are different definitions. Mr. Conner noted that the Comprehensive Plan spoke to “primary areas”
but the Land Development Regulation gave no direction as to how to interpret that because there is no
specific standard for interpretation. The grasslands, prime ag and shrublands in Map 8 were secondary,
and were not tested as to relevance. Mr. Conner then enumerated what is now being covered that was
not previously covered including: 500-year flood plain, measurements from streams for buffers, no
incursion into wetlands, habitat blocks throughout the city, steep slopes over 20%. He said th is is
substantially more than is currently protected.
Mr. Conner said that to regulate what Mr. Mittag wants would need specific standards or it would be
difficult to uphold.
Ms. Dooley noted that Mr. Mittag’s motion contradicts what the Commission just approved. Mr. Mittag
acknowledged that.
Mr. Engels asked Mr. Conner to indicate what protections are lost. Mr. Conner said the text in Chapter 9
refers to a Comprehensive Plan map which refers to statewide data. It is hard to say what is gained or
lost.
In the vote that followed the motion was defeated 3-4 with Ms. Ostby, Ms. Louisos, and Messrs.
Macdonald and Gagnon voting against.
Members agreed to pick up at the next meeting from where they have left. Off.

As there was no further business to come before the Commission, the meeting was adjourned by
common consent at 9:49 p.m.

RE: Report on Proposed Amendments to the City’s Unified Land Use and Development
Regulations including Articles III and X; and Sections 4.9 and 6.6
DATE: March 12, 2021
________________________________________
This memo provides information related to proposed amendments to the City of Winooski Unified Land
Use and Development Regulations. These amendments specifically impact the following articles and
sections:
• Article III - Reserved
• Article X - Maps
• Section 4.9 - Nonconforming Lots, Structures Right of Way (ROW) or Drive, and Uses
• Section 6.6 - Site Plan Review
These amendments also replace references to “Appendix C” with “Article III”, move the “Building Height
and Location Map” from Appendix C to Article X, and delete Appendix C in its entirety.
Background
In 2016, the City undertook a comprehensive update to the Unified Land Use and Development
Regulations (ULUDR). This was the first update in over 20 years. A major component of this update
included a new Appendix B, which provides regulations for the Gateway Zoning Districts through the
form-based code. While these changes modernized the regulations, staff has identified additional
amendments to provide clarity and improve the interpretation of the regulations. Additionally, several
conflicts exist that need to be rectified. With this in mind, staff has been reviewing each section of
the ULUDR and proposing amendments to the Planning Commission for their consideration.
Purpose of Amendments
These amendments are being proposed to provide clarity for interpretation of the regulations, and to
update and incorporate specific regulations related to the Downtown Core Zoning District, including
regulatory references contained within the standards. The City developed and adopted regulations
related to the Downtown Core Zoning District over several years including multiple interim zoning

changes. With the complete update and codification of the regulations, the standards for development
in the Downtown Core Zoning District were included as Appendix C, but did not include referential
updates.
The proposed amendments will incorporate the specific use standards for the Downtown Core Zoning
District into Article III (which is currently reserved) and adds language related to the process of review
for projects in the Downtown Core Zoning District including the City Council review for design
consideration in the Act 250 permitting process including references to the master sign plans that have
been adopted for the Downtown Core Zoning District. These amendments also add clarification related
to site plan review, including properties in the Downtown Core, as well as clarification for non-
conformities including properties in the Downtown Core.
Finally, the amendments would replace references to “Appendix C” with “Article III” to recognize the
relocation of these regulations. These amendments also add the “Building Height and Location Map”
currently included in Appendix C to Article X, which includes other zoning maps. Minor map changes
update road names and incorporate the entirety of Cascades Way, but do not change any of the
specific regulatory requirements associated with the building heights, locations, or development areas.
If approved, these changes will result in the elimination of Appendix C as all information will be
relocated to other sections of the Unified Land Use and Development Regulations.
Proposed Amendments
The following pages include the text of Articles III and X; and Sections 4.9 and 6.6 including proposed
changes. Proposed additional text is shown in red and underlined. Text that appears with a strikeout
is proposed to be deleted. If specific sections are not included, no changes are being proposed in these
sections. For the purposes of this amendment, language contained in Article III has been transposed
from Appendix C. While all of this text is new to Article III, the construction of the amendments are
intended to reflect existing regulatory language that will remain in the context of changes that are
being proposed.

Consistency with the Winooski Master Plan
The following information is provided to address the requirements of 24 V.S.A. §4441 regarding
consistency of the proposed amendments to the City of Winooski Master Plan, adopted March 2019.
Specifically, statute requires municipalities to consider three parts when reviewing proposals for new
or amended bylaws. These considerations include:
1. Conforms with or furthers the goals and policies contained in the municipal plan, including the
effect of the proposal on the availability of safe and affordable housing.
The City updated their Master Plan in 2019. The master plan includes multiple components that
discuss housing options and affordability, and protection of existing stable neighborhoods. The
proposed changes are primarily administrative in nature and would not adversely impact the
availability of safe and affordable housing. Additionally, these changes would all be consistent
with the goals and polices in the Master Plan.

RE: Proposed CDO Amendment ZA-20-05: Short Term Rentals & Ch. 18 Minimum
Housing Code amendments
Overview & Background
This package of amendments resulted from the 2019 Mayor’s Housing Summit, and the subsequent
Council Resolution in October 2019, which directed a Joint Committee of the Planning Commission &
City Council Ordinance Committee to create a regulatory framework for short-term rentals that
created tiers and disincentivizes the most impactful uses in order to:
Limit the number of housing units converted for short-term rental purposes;
Ensure that conversions contribute to efforts to preserve and expand affordable housing;
Provide some flexibility for homeowners to earn income; and
Recognize that some supply of short-term rentals benefits the Burlington economy.
Defining Short Term Rentals
A short term rental (or STR) is typically a dwelling unit that is rented in whole or in part to guests for
less than 30 consecutive days for overnight stays. It may be an apartment, a house, or just a bedroom
within a housing unit. AirBnB exemplifies short term rentals.
In the last several years, there has been significant and growing demand for STR’s internationally, and
locally. They benefit owners with a source of income that can help subsidize a cost of living that may
otherwise be unaffordable. STR’s may also encourage investment in a property. They benefit
Burlington’s tourism economy and provide guests with a convenient, and often more affordable,
place to stay when traveling. They also generate city and state tax revenue via the Rooms & Meals
Tax (RMT). Short term rentals, however, do not come without impacts. Some have the effect of
removing dwelling units for long-term occupancy, and they may contribute to rising rental rates and
purchase prices. Given the high turn-over of guests, short-term rentals may bring about nuisance
impacts such as traffic, noise, and trash to neighborhoods.
As the Joint Committee has heard from many of the city’s STR hosts, short-term rentals are uniquely
flexible and come in a variety of forms—beyond the major distinction between whole unit and partial
unit STR’s. The same dwelling unit may alternate between long- and short-term rental uses within a
relatively short period of time. A dwelling unit may serve as one’s primary residence for most of the
year, and serve as a short-term rental while the resident is away. A short-term rental may coexist
with a number of long-term rentals within a multi-family building. This variability and flexibility needs
to be considered within the context of the overarching policy objective: to protect Burlington’s limited
housing stock, while affording reasonable opportunity to host short-term rentals within the city.
Short Term Rentals in Burlington
Burlington has some 10,000+ rental housing units, representing 60% of all housing units. While the
June 2019 Housing Summit reported hopeful trends in a slightly increasing vacancy rate and slight
slowing annual rent inflation, the city’s housing market remains tight with the long-time rental
vacancy rate between 1% and 2%. Short-term rentals have replaced a growing number of dwelling
units citywide in recent years. According to data provided by HostCompliance, the number of short
term rentals within Burlington increased 26% between 2018 and 2019. The average monthly number
of short term rentals within city limits between June and September 2020 was 403 listings,
representing 357 unique rentals.
As of September 2020, 71% STRs in Burlington are an entire dwelling unit, whereas 29% are partial
dwelling units (i.e. bedrooms). This is a change from 67% and 33% respectively in 2019, likely due to
COVID-19 concerns. In September 2020, 55% of the city’s STR’s were in single-family properties and
45% in multi-family properties. The COVID-19 pandemic has had wide-ranging impacts on the STR
market globally and locally.
While the total number of unique properties and listings in Burlington has changed little in 2020, the
number of active listings has varied this year due travel restrictions and hosts’ management
decisions. Stories shared by STR hosts and data from other sites, such as AirDNA, suggest that many
of these listings may currently be inactive, are being rented as an STR for a longer duration (such as
for weeks or months), or are being used as temporary accommodations for people who have
relocated due to the pandemic. It will be some time before the long-term impacts of COVID-19 on
the local STR market are understood.
Joint Committee work on STR Proposal
The Joint Committee has received information on STRs in the city during meetings spanning more
than a year. In response to public and Joint Committee comments, the original draft regulatory
framework has been revised in four major ways:
Revision to STR limits within multi-unit buildings to be less than 50% of units, a prohibition on
STRs in buildings with 5 or more units, and a related clarification that exceeding these limits
results in a “lodging” use.
Allow some degree of off-site hosting for STR’s within multi-unit buildings.
Consider an alternative to Housing Replacement fees, such as an additional fee based on
STR income. In either scenario, fees will support the City’s Housing Trust Fund. This additional
fee needs to be determined by the City Council, and likely through a charter change.
Specifically enable hosts to short term rent their primary residence, no matter the residential
building type.
The standard for when the host is required to live on or be the owner of the property hosting an
STR(s) emerged as one of the most important policy levers in determining how many STRs would be
possible within the city. The Committee deliberated this issue on many occasions, specifically with
regard to how permissive the policy should be, and what recourse the City had for changing the
policy or curtailing STR use if too many housing units became STRs.
As a result, staff provided a proposal for the Joint Committee’s consideration to shift much of the
regulatory framework from the Comprehensive Development Ordinance (CDO) to Chapter 18: Minimum
Housing Standards (Ch.18) of the City’s Code of Ordinances. This shift would preserve the ability to
implement key policy objectives, but leaves a limited role for zoning regulation of STRs. Specifically,
Ch. 18 can regulate the number of STRs permitted on a property or in a building as well as host-
occupancy requirements where applicable. Ch.18 continues to be the tool to administer life safety
standards and the annual rental registration process.
Moving STR standards out of the CDO has several benefits, such as avoiding the onerous process of
requiring new zoning permits each time a unit switches from long-term and short-term use. But most
significantly, it addresses the Committee’s feeling that the policy may need to be adjusted in the
future, and eliminates the concern that non-conforming STRs would be exempt from such changes.
Because standards in Ch.18 apply at the time of each annual rental registration, any policy changes
made since an STR’s last permit renewal would be applicable.
Therefore, the limited role for regulating STR’s through the CDO includes allowing STR’s by-right
where residential uses are permitted, and creating a definition that points to the specific STR
regulations in Ch. 18. This amendment also condenses the definitions for several lodging types into
one use/definition, and clarifies that they do not include STRs.
Proposed Amendment
Amendment Type
Text Amendment Map Amendment Text & Map Amendment
Purpose Statement
The proposed regulatory framework is aimed at minimizing the potential for adverse impacts to
the city’s housing stock, while balancing some flexibility for hosts to operate short term rentals.
Together with amendments to Minimum Housing Standards in the City’s Code of Ordinances,
the proposed amendment is intended to allow the short term rental of bedrooms within a
dwelling, and the use of a host’s own dwelling occasionally as a short-term rental, with minimal
burden to the host. Per-building caps are applied to whole unit short term rentals operated by
off-site hosts so as to limit their proliferation. In an effort to balance the benefits to hosts with
the preservation of long-term housing stock, short term rentals would generally be allowed
wherever residential uses are allowed; however, in most scenarios, hosts must be a resident of
the property.
Proposed Amendments
CDO Amendments
With the shift of much of the regulatory framework to Ch. 18, only limited changes to the
Burlington Comprehensive Development Ordinance are now proposed:
1. Amend Article 13 Definitions to define “short term rental”, modify “lodging” definitions
Define short term rental as a type of dwelling unit and refer to standards in Ch.18. The STR
definition reflects the state’s definition of an STR with regard to length of rental and refers
to the Vermont rooms and meals tax. Additionally, the definitions of Hotel/Motel and
Hostel are streamlined to a more general “Lodging” definition to reduce redundancy and
inconsistencies in how various traditional lodging uses are permitted.
2. Add STRs as a “special residential use” to Appendix A- Use Table and in Article 14-
Downtown Code
This will establish that short term rentals are allowed anywhere that residential uses are
allowed, and will refer to Ch. 18 for specific standards.
Ch. 18 Minimum Housing Code Amendments
The attached documents detail the related amendments to Ch. 18 Minimum Housing Standards.
While Ch. 18 amendments are not normally the purview of the Planning Commission, they are
reviewed by the City Council Ordinance Committee. Further, in this instance, the Joint
Committee is recommending Ch.18 amendments because they resulted from the Committee’s
charge from the City Council to create a regulatory framework for STRs. These amendments
include:
1. Establish standards for the number and type of STRs permitted in a building, and when
the host is required to be the owner/occupant of the property.
Sets limits for the number of bedrooms rented in a Partial Unit STR, and limits for the
number of Whole Unit STRs permitted in a building based on the number of units in the
building. Additionally, requires host occupancy of the unit in which the STR is located
except for in limited cases for STRs in multi-unit buildings of 3 or 4 units.
2. Establish minimum life safety standards for STRs, and requirements for annual rental
registration.
Defines a limited set of life safety standards for STRs, and additional information to be
provided on rental registration applications for housing units to be used as STRs.
Relationship to planBTV
This following discussion of conformance with the goals and policies of planBTV is prepared in
accordance with the provisions of 24 V.S.A. §4441(c).
Compatibility with Proposed Future Land Use & Density
The STR proposal is intended to protect existing housing from unlimited conversion to short term
rental use. Data shows increasing numbers of short term rentals in recent years, largely at the
expense of long term housing stock. This increase puts additional pressure on the city’s available
housing and degree of affordability. The proposed measures will establish parameters for
allowing short term rentals while limiting their adverse impacts on the city’s housing supply and
affordability.
Impact on Safe & Affordable Housing
The proposal will have no impact on the intensity or density of future land use. It will; however,
ensure that future short term rentals are compatible with the residential neighborhoods that so
many of them occupy. Short term rentals will be allowed wherever residential uses are allowed.
Per-building caps will prevent wholesale conversion of residential units into short term rentals.
Planned Community Facilities
This amendment has no impact on any planned community facilities.
