1.
a. Authority.
i. The Development Review Board (DRB) has the authority under 24 VSA § 4417 to
review, and to approve, to approve with modifications and conditions, or to
disapprove an application for a Planned Unit Development (PUD).
Acknowledged.
ii. The DRB also has the authority to modify the Land Development Regulations in
association with PUD review, subject to the standards and conditions for
Planned Unit Development, as specified by PUD type under this Article, in
support of more efficient, compact, walkable, and well-planned forms of
residential neighborhood, mixed-use, and infill development, and the
permanent conservation of resource lands and other open space.
Acknowledged and waivers are requested.
1. In addition to modifications or waivers intended to accommodate site
constraints under Section 15.A.01 of the subdivision regulations, this
may include modifications of underlying zoning and subdivision
regulations pertaining to blocks, building lots, building types, allowed
densities of development, and the type and mix of allowed uses.
2. This may also include DRB review and approval of alternative forms of
compliance with applicable PUD standards under Section 15.C.04.
b. Purpose. - The purpose of a Planned Unit Development (PUD) is to promote a more
comprehensive, unified, and integrated form of planned development that may vary
from the strict standards of underlying zoning and subdivision regulations, to achieve
stated community goals and objectives in conformance with the Comprehensive Plan.
Specifically, it is the intent under this Article to allow for types of planned development,
in locations appropriate to each type, that:
• Promote the most efficient and cost-effective use of land, infrastructure, facilities and
services;
• Offer flexibility, within defined parameters, to best achieve the intended purpose,
design and function of a PUD within the context of a particular site and its surroundings;
• Exclude or conserve, as determined by PUD Type, natural resources identified for
protection under Article 12;
• Complement, connect, and fully integrate new development with adjoining
neighborhoods, properties, and uses;

• Foster more traditional forms of compact, walkable, pedestrian-oriented residential
neighborhoods and mixed-use development;
• Incorporate a well-integrated variety and mix of housing types and styles that serve a
range of incomes, ages, and household sizes.
• Incorporate transit-supportive types and densities of development along existing and
planned transit routes;
• Encourage viable forms of compatible infill and redevelopment in previously
developed areas of the City served by municipal water, wastewater, and stormwater
management systems; and
• Provide opportunities for energy-efficient development and redevelopment, including
solar energy facility installations appropriate to the development context.
15.C.02 Applicability
a. Floating Zone. For purposes of these Regulations, a Planned Unit Development (PUD) is an
unmapped overlay zoning district or “Floating Zone,” as allowed or required within an underlying
zoning district, which is applied to a particular tract or parcel of land proposed for subdivision and
development. A PUD is intended to function as a more flexible, design-based zoning district in which
conservation or form-based design district, site plan, or subdivision standards, PUD standards shall
apply.
b. PUD Types. - The following types of Planned Unit Development are authorized under these
Regulations by Zoning District (Table 15.C.1), subject to the associated provisions and standards of
review for each PUD type:
(1) Conservation Development (CON PUD) under Article 15.C.05 Not Proposed
(2) Traditional Neighborhood Development (TND PUD) under Article 15.C.06 Not Proposed
(3) General PUD under Article 15.C.07 – Proposed
c. Required Planned Unit Development. - PUD review and approval by the DRB under this Article is
required for any subdivision and development of a tract or parcel with a total area of four (4) or
more acres This property has 10.05 acres within any zoning district listed for CON PUD and TND
PUDs under Table 15.C-1 The I-O District is not listed under these two PUD Types.. General PUDs
are not mandatory in any district.
d. Elective Planned Unit Development. - An applicant may elect PUD review, as allowed within
specified zoning districts, for the subdivision and development of any tract or parcel of less than four
(4) acres, Not Applicable as this parcel includes 10.05 acres. that qualifies as:
i. A Conservation PUD under Subsection 15.C.05, in which fifty percent (50%) or more of the total
tract area includes one or more Hazard or Level I Resource areas identified for protection under
Article 12.

Note! In return for the flexibility and increases in density afforded Planned Unit Development
projects under this Article, it is expected that applicants and developers will adhere to higher
standards of subdivision, site plan, and building design.
ii. Where the General PUD type is allowed under Table 15.C-1 or Section 15.C.07(C).
e. PUD Type by Zoning District. - The types of PUD allowed within an underlying zoning district are
specified by district in Table 15.C-1.
Table 15.C-1 PUD Types by Zoning District
PUD Type Underlying Zoning Districts
General PUD (1) C1-R12, C1-R15, C1-AUTO, C1-AIR, C1-LR, C2, IC, AIR, AIR-I, I-O and IA.
(2) As described in Section 15.C.07 (C).
i. Planned Unit Development review under this Article does not apply to
subdivision and development within those zoning districts for which no PUD
type is specified. In addition:
1. All PUD types are prohibited within the SEQ-NRP Subdistrict Not
applicable as this property is located in the I-O District; except for land
on a tract or parcel within the SEQ-NRP that is included for conservation
within a Conservation PUD.
ii. A Conservation PUD under Section 15.C.05 is required for the subdivision and
development of a tract or parcel of four (4) or more acres within the following
SEQ Sub-Districts: SEQ-NR, SEQ-NRT, and SEQ-NRN Not applicable as this
parcel is located in the I-O District. A Conservation PUD is elective in other
listed zoning districts; and in any zoning district in which PUDs are allowed, for
tracts or parcels of two (2) or more acres in which fifty percent (50%) or more of
the total tract or parcel area consists of Hazards or Level I Resources identified
for protection under Article 12 Not applicable as less than 10% of the property
is limited by the presence of Hazards or Level 1 Resources.
iii. Where more than one PUD type is allowed within the underlying zoning district
Not applicable as this property is only eligible for General PUD, the applicant
may select the PUD type applicable to their project unless specifically stated
otherwise.
iv. A PUD that includes land in two or more underlying zoning districts Not
applicable must be an allowed PUD type in each zoning district. In association
with Master Plan or PUD approval, the DRB may, within the area included in the
PUD:
1. Extend underlying district regulations, and associated PUD provisions,
by up to fifty (50) feet in either direction of the zoning district line.
2. Require a designated “Transition Zone” under Subsection 15.C.04(E),
within or along the district boundary or the delineated PUD perimeter,
15.C Planned Unit Development Compliance Review

as necessary to mitigate the impacts of development on adjoining
properties and uses.
f. Multiple PUDs. - Multiple PUDs per tract may be allowed Not applicable and the
remainder removed for brevity
B. Application Requirements.
1. A PUD application may involve one or more contiguous properties under single or multiple
ownership, if incorporated under a common PUD application; however, all properties must
come under the direct control of the applicant or developer as required for subsequent
permitting and development. This application involves one landowner.
2. In addition to Preliminary Subdivision and Master Plan Review submission requirements under
Sections 15.A.06 and 15.B.04, the application for a proposed PUD must include the following:
a. A statement and description of PUD conformance with the City’s Comprehensive Plan in
effect at the time of application, including applicable land use, development, and
infrastructure policies specific to the area proposed for development. The property is
located in the future Commercial/Industrial with Supporting Uses portion of the Future
Land Uses section of the City’s Comprehensive Plan. We have inserted the specific
language below for further review and comment.
COMMERCIAL/INDUSTRIAL WITH SUPPORTING USES AREAS
While the City’s principal transportation corridors – notably Shelburne Road and Williston
Road west of Kennedy Drive/Airport Drive – have begun a transition to mixed use areas, the
City has many areas that are presently exclusively commercial/industrial. These include
Technology Park, Tilley Drive, the Meadowland Business Park, Kimball Ave, the east end of
Williston Road, and areas north of the Airport, among others.
COMMERCIAL/INDUSTRIAL WITH SUPPORTING USES AREA GOALS
Goal 80: Reduce commuting distance and daytime vehicle travel by integrating supporting
services to commercial areas
Goal 81: Make commercial areas more diverse in spaces, styles, and uses to enable more
nimble commercial use
COMMERCIAL/INDUSTRIAL WITH SUPPORTING USES ACTIONS
Action 137: Evaluate existing business park areas for appropriately integrated housing
Opportunities. The proposed WGM Associates subdivision creates new housing in close
proximity to existing commercia;/industrial uses.
In recent decades, most business uses have become quieter and less noxious, like retail,
office space, and light manufacturing. For most modern commercial uses, being located near
residential uses is less likely to cause conflict. As the need for housing has increased and the
desire (for many reasons) for people to live closer to their workplaces has increased,
planning for commercial areas also must shift to allow more residential uses in formerly
15.C Planned Unit Development Compliance Review

commercial-only areas. The timing is appropriate to review past policy and consider
assigning more areas of the city to allow a mix of uses. The residential density
opportunities exhibited in recent State statute changes enable the density in this area to
become viable.
It is not the intention of this plan that commercial areas will transform to residential areas.
Instead, we recognize that some limited residential uses will enhance and support the future
of our primarily commercial areas. In these areas with more commercial visual character,
housing may take on a non-traditional appearance and have more flexibility for innovative
design to fit with the area. This project represents and infill to the existing residential
homes that front Hinesburg Road.
In addition to adding mixed/residential use to commercial areas, the commercial areas need
to adapt to the future of work, employment, and commuting. Many of our commercial areas
are not well connected to the bike/ped transportation network or are located on busy
transportation corridors that could be improved for bike/ped safety and efficiency. Business
parks are designed for large buildings on large lots. These spaces are necessary, but we must
also have a healthy range of building sizes, lot sizes, and intensities of building on
commercial lots. South Burlington needs to have land, lots, and buildings that accommodate
a range of commercial entities from small retail shops to startups to large manufacturing. A
sufficient supply of commercial spaces will ensure commercial costs remain competitive.
Maintaining such a supply requires planning for land and space for those uses. The
proposed mixed use on Lot 1B enables the integration of both existing commercial and
new housing to exist together.
b. Documentation of project conformance with any proposed, previously approved or
amended Master Plan for the PUD in effect at the time of application. Not Applicable as this
property is not subject to any prior Master Plan or PUD approvals.
c. A statement and description of project conformance with the description, intent, and
defining characteristics of the PUD type(s) proposed. The narrative addressing conformance
with the stated goals of the General PUD may be found within this document within
section 15.C.07 General PUD(B).
d. A statement and description of how the proposed PUD complies with the design standards
specific to the selected PUD type(s). This document proposes to satisfy this requirement.
i. A list and description of requested modifications, waivers, or other forms of relief from
the strict standards of these Regulations sought through PUD review, including applicable
zoning district, subdivision, site plan, or PUD standards and associated mitigation
measures; including any proposed alternative forms of compliance under Section
15.C.04. The items in which waivers or some form of relief is sought is highlighted in
green in this and the other compliance documents. They are assembled in standalone
document to demonstrate compliance with this requirement.

15.C.04 PUD Standards Applicable to All PUD Types
A. Conformance with the Comprehensive Plan. - The proposed PUD must conform to the City’s
Comprehensive Plan in effect at the time of application. Conformance with the plan in this
context means that the proposed PUD must:
a. Advance any clearly stated plan policies and objectives specific to the type and location
of the proposed development; The type of project is small scale housing and the
location is east of Hinesburg Road just south of I-89. The project provides an infill
opportunity (discussed in the Housing Section) for additional residential homes
located within a commercially zoned area (discussed in the Land Use section).
b. Incorporate preferred settlement patterns, including future land uses, densities and
intensities of development referenced in the land use plan, as implemented through
planned unit development provisions specific to each PUD type. The project provides
new housing intermixed within the I-O District and specifically within the Commercia-
Industrial with supporting Uses portion of the Land Use section fo the Comprehensive
Plan.
c. Incorporate, as applicable, planned facilities, services and infrastructure identified in the
utilities and facilities plan, as implemented under the City’s adopted Capital
Improvement Program (CIP) and Official Map. There are no proposed facilities
identified in the Official Map near this property.
B. Conformance with the Master Plan. - Each phase of a PUD developed in one or more phases
must conform to the PUD Master Plan, as approved or amended by the DRB under Article 15.B,
including the approved development plan, phasing schedule, buildout budget, management
plan, and any associated development agreements or conditions of master plan approval. As
this project is not already subject to a prior Master Plan approval, this PUD application
represents Phase I of the Master Plan for this property. The development plan, phasing plan
and build-out budget are all attached as part of the Master Plan application package.
C. Compliance with Regulations. - The provisions and standards specific to a PUD under this Article
supersede underlying zoning district, subdivision, and site plan standards. In no case, however,
shall the provisions or standards specific to a PUD supersede the Environmental Protection
Standards of Article 12 Acknowledged but this seems to be in conflict with a stated purpose of
the PUD process which states ….. • Exclude or conserve, as determined by PUD Type, natural
resources identified for protection under Article 12 . Notwithstanding the supersession of the
underlying zoning district, subdivision, and site plan standards, any application that indicates a
density increase that exceeds the Assigned Density of a parcel shall require a TDR under Article
19. Not applicable as the proposed density falls well under the allowable 5-unit per acre
density of the available buildable area
15.C Planned Unit Development Compliance Review

i. A PUD must comply with any applicable provision or standard under these
Regulations that is not superseded, modified, or waived by the DRB in
association with PUD review Acknowledged.
ii. A PUD must also comply with other applicable city ordinances and regulations
listed under Section 15.A.11(C) Please see the conformance review for Article
15.A in effect at the time of application, including the following, unless modified
or waived by the DRB in consultation with city or state officials having shared
jurisdiction.
a. Official Map. The PUD must incorporate planned public facilities and capital
improvements included in the City’s adopted Official Map and Capital
Improvement Program (CIP) in effect at the time of application, unless
modified or waived by the DRB. The Official Map and the CIP do not call
for any improvements or investments in this area.
b. Impact Fees. Development within the PUD is also subject to impact fees
enacted and levied under the City’s impact fee ordinance; however, if the
applicant or a subsequent developer is required, in association with PUD
approval, to provide land or to construct a facility explicitly included in the
calculation of an impact fee, they may then receive credit against the impact
fee in an amount equal to the value of the dedicated land or cost of
construction. Acknowledged.
iii. Alternative Compliance. One or more PUD dimensional and design standards
under this Article may be modified at applicant request for an alternative form
of compliance, subject to separate DRB review and approval, to provide the
flexibility necessary to address unique site conditions or constraints; to enable
compatibility with existing or planned development in the vicinity; or to allow
for exceptional and innovative design. Note that alternative compliance does
not constitute an exemption from a PUD standard. Allowed modifications
include proposed functional or design alternatives that may be considered in
place of a specific requirement under this Article, only if the intent of the
requirement is met or exceeded. In approving a request for alternative
compliance, the DRB must find that the proposed alternative: This will be used
for the proposed elimination of the need to place a bituminous surface and
curbing on the private road and to construct a dedicated sidewalk on a low
volume roadway.
Elimination of Bituminous Surface
a. Conforms to the intent, description, and defining characteristics of the
selected PUD type(s); This proposed modification is not specifically
addressed in the PUD standards beyond an implied requirement to
conform with the underlying regulations which in turn reference the newly
adopted Public Works Standards. Those regulations provide the manner
in which the components are to be installed which the applicant will
15.C Planned Unit Development Compliance Review

conform to, but it is also represents products that represent the lowest
level of maintenance for a typical City street. The proposed street is not
typical (very low volume) and is not to be offered to the City. Under these
conditions the DPW’s interests are minimized and the remaining Public
Safety issues are relegated to reasonable emergency access. The
proposed width of the street is not proposed to be narrowed beyond that
called for in the street typology standards and the maximum street
gradient called for in the public works standards will not be exceeded.
b. Achieves the intent of the PUD standard to be modified; The primary
purposes of a bituminous surface is to reduce infiltration, provide a more
durable surface for large vehicle use roadways and to reduce surface
maintenance requirements for highly travelled roadways. An additional
benefit is that the road surface warms up quicker in winter conditions
when exposed to sunlight.
Low volume roadways can function without a bituminous concrete
wearing surface. In fact, the majority of the roads in Vermont function in
this way. The balance point of when a road needs a bituminous surface
occurs when the amount of maintenance required to keep the gravel
(crushed stone surface) road operational exceeds the annualized cost of
placing and maintaining the bituminous concrete surface. The
maintenance component must take into account the requirement to
provide subsequent surface treatments of the bituminous concrete
surface to prevent it from losing its flexibility (becoming brittle) and
subsequently having to be replaced altogether.
A previous white paper study completed for the Town of Shelburne
indicated that, all things being equal, that this break point generally occurs
when approximately 40 to 50 residential units and associated traffic is
travelling on a roadway (See Attached Exhibit H - When to Pave a Gravel
Road). For low volume roadways, a gravel surface, or in this case a
superior crushed stone surface, can function in a suitable and less
expensive manner than a road with a bituminous concrete surface.
Surface management of the proposed road is intended to be minimized
through the use of an aggressive (3%) crown to remove the surface water
from the road surface as quickly as possible. The existing access drive and
parking area for the Wright Transportation Trucks are all constructed of
crushed stone materials placed over a stabilization fabric. Normally, an
intersection with a high volume of turning movements can create a higher
level of maintenance. As it turns out, the turning movement of the 100
PSI truck tires (a passenger vehicle tire typically runs at 30-35 psi) for the
15.C Planned Unit Development Compliance Review

Wright Transportation trucks entering and exiting from Hinesburg Road
has been managed without issue with the existing crushed stone surface.
This application proposes to utilize the same pavement section as that
used in the existing infrastructure on this property. This is depicted on
Sheet C4.0 Road Profile and Details (Exhibit A). As a condition of approval
with VTrans, this application does include the proposed paving of the
apron of the road entering out onto Hinesburg Road consistent with
design requirements set forth in the attached Exhibit B - VTrans Design
Standard B-71B for commercial roads. This is primarily intended to
minimize stone (from gravel road surfaces) from being deposited onto the
State highway travel surface.
c. Results in development that is equivalent or demonstrably superior in
function, design, and quality to that required under the standard to be
modified; and The proposed design without the use of a bituminous
surface is time proven throughout Vermont as being more cost effective
and has a lower carbon footprint when the production of the asphalt is
removed from the equation for the initial and future phases of the road
maintenance. Alternately, some believe that paving of a driveway or
roadway, when not structurally required, can provide some aesthetic
benefits.
d. Does not adversely impact properties, uses or facilities within, adjacent to,
or in the vicinity of the planned development (e.g., regarding walkability,
traffic, parking, drainage). The DRB in approving an alternative form of
compliance may attach conditions as necessary to ensure compliance, or to
mitigate any adverse impacts resulting from a proposed alternative. The
proposed use of a crushed stone surface will be consistent with the
existing conditions which occupy the first 250’ of the existing access way
from Hinesburg Road. The proposed use of the road is very low volume
(84 VTE, See Page 5 of Exhibit C - Trip Gen Summary, Phase I). This low
volume and low speed will mitigate what otherwise could be issues with
dust generation or disturbance of the surface. Stormwater runoff is
managed with pretreatment and polishing through a gravel wetland in the
same manner as a paved road is required to be managed.
Alternative Sidewalk
a. Conforms to the intent, description, and defining characteristics of the
selected PUD type(s); This project is being reviewed a General PUD. More
specifically this is also being reviewed under Article 15A as a subdivision.
The intent being to be able to provide a safe environment for pedestrians
to move along the transportation corridor. The modeled vehicle trip
generation (See Exhibit C, Page 5 Trip Gen Summary) for Phase 1 identifies
15.C Planned Unit Development Compliance Review
WGM Associates, Inc.

Maxine’s Way as having 84 VTE at the intersection with Hinesburg Road.
Since this will be a dead-end road in Phase I (with this application), the
VTE on this road decrease as one moves easterly away from Hinesburg
Road. The State of Vermont Agency of Transportation (VTrans) has
prepared State Design Guidelines to provide direction of consistent design
of roadways. Within this document it specifically indicates that for
roadways with design VTE of less than 100 vehicles per day, that bicycle
and pedestrian traffic can be accommodated within the roadway surface
without additional infrastructure (See attached Exhibit D - VTrans Design
Guidelines). This represents a practical balancing of safety conflicts and
cost benefit. The AM and PM peak hour generation are respectively 5 and
6 vehicle per hour (Exhibit C – Trip Gen Summary). An average of one
vehicle every 10 minutes. With this being a low volume, low speed
roadway with width that exceed the recommended minimum, pedestrian
and bicycle movements can safely be accommodated within the proposed
20-foot road surface.
b. Achieves the intent of the PUD standard to be modified; The intent is to be
able to provide pedestrians and bicyclists a safe environment to move
through the roadway corridor. As evidenced in the design guidelines
outlined above, public policy guidelines indicate that pedestrians and
bicyclists can be safely accommodated within the common roadway
surface without the need for supplemental infrastructure for very low
volume roadways.
c. Results in development that is equivalent or demonstrably superior in
function, design, and quality to that required under the standard to be
modified; and The narrative above addresses the guidance related to a
“share the road” approach relative to pedestrian accommodation when
associated with a very low volume roadway. From a resource
conservation approach, the consolidation of what otherwise would be a
separate standalone sidewalk, the applicant’s proposal is notable as it
relates to the reduction of impervious surfaces, reduction of high CO2
impact materials (concrete) and dedicated maintenance.
d. Does not adversely impact properties, uses or facilities within, adjacent to,
or in the vicinity of the planned development (e.g., regarding walkability,
traffic, parking, drainage). The DRB in approving an alternative form of
compliance may attach conditions as necessary to ensure compliance, or to
mitigate any adverse impacts resulting from a proposed alternative. The
consolidation of the pedestrian, bicycle and vehicular facilities into one
transportation corridor will have no impact on the properties that abut
15.C Planned Unit Development Compliance Review

this proposed PUD due to the remote proximity of the project from their
respective transportation facilities.
Alternative Drainage and no curbing for Typical Street Section
a. Conforms to the intent, description, and defining characteristics of the
selected PUD type(s); The specific standards in the LDRs (Exhibit E - Article
11A – Street Typology) speaks to a design roadway width of 20-feet and a
design speed of 25 MPH. The proposed road section with this application
embraces this width and design speed requirement. However, there is no
other guidance on the crown, gradient, curbing or drainage management
relative to the 11 different street typologies outlined in Article 11A of the
LDRs.
The recently published Public Works Standards and Specifications provides
only one typical detail for a street section (Exhibit F – DPW Standards.pdf).
It shows the use of concrete curbs which in turn requires the use of an
enclosed drainage system to collect and convey stormwater runoff.
Within the Industrial Open Space District, the Department of Public Works
specifically asked that the Randall Street-North (which intersects with
Meadowland Drive) typical road section eliminate the curbs in favor of
open swales (ditches) on either side of the road. This was most recently
reinforced with the Booska Movers approval which adopted for the future
public street (Randall Street south) a typical section which eliminated the
curbing in favor of roadside swales (See Exhibit G - Booska - C5.3 ROAD
DETAILS). The typical design for the Maxine’s Way street section call for
the introduction of a swale on the uphill side of the road with a stabilized
stone conveyance swale capped with sandy loam disconnection shoulder.
The cap includes an linear chimney drain to remove concentrated flows
from the surface of the cap to reduce the potential for erosion (See Exhibit
A - Sheet C4.0).
b. Achieves the intent of the PUD standard to be modified; Normally the
intent of the curbing is to delineate the boundaries between road and
sidewalk, it serves as a tool for traffic management and to control
stormwater runoff. In this case the need for sidewalk separation and
traffic control is not required due to the low volume of the roadway.
Stormwater management is actually impaired by eliminating
disconnection treatment between the road surface and the swale. The
elimination of the need for catch basins and enclosed drainage pipe
conveyance systems in favor of a swale is more synonymous with natural
conditions. The adoption of open swales, when space permits, provides a
higher level of Stormwater treatment and a more open feel to the area.

c. Results in development that is equivalent or demonstrably superior in
function, design, and quality to that required under the standard to be
modified; and Curbs are used in manner urban development scenarios
when there is not space to allocate to shoulders and transitional slopes
into and out of parallel swales. But is area that have the space to
accommodate the features, the use of a grassed shoulder and slope with a
parallel swale system to collect and convey the stormwater from the road
and surrounding areas, provides an improved level of treatment compared
to the curbing and catch basin system.
d. Does not adversely impact properties, uses or facilities within, adjacent to,
or in the vicinity of the planned development (e.g., regarding walkability,
traffic, parking, drainage). The DRB in approving an alternative form of
compliance may attach conditions as necessary to ensure compliance, or to
mitigate any adverse impacts resulting from a proposed alternative. The
proposed elimination of curbing, for those low volume, shared use
roadways, will not impact parking (there is no parking allowed on the 20’
wide Neighborhood Street-Narrow typology), will eliminate plow damage
of the curbs, especially at driveway intersections, and will augment initial
stormwater treatment. It will not impact abutting properties to the PUD
and will create a more rural feel consistent with the goals of the family
members and to better mimic the open nature of the surrounding
properties.
Alternative Vertical Profile K Values at end of the Road
a. Conforms to the intent, description, and defining characteristics of the
selected PUD type(s); The LDRs do identify a design speed for new roads
but do not speak to the horizontal or vertical alignment of new roads. The
newly published Department of Public Works Standards and Specifications
do provide guidance on those characteristics. These design values are
documented on Exhibit A - Sheet C4.0 and Exhibit F - DPW Standards -
Abridged. For vertical alignment, a design “K-Value” defines the length of
the vertical curve connecting two tangent grades.
The intent of the “K-Value” in developing the vertical alignment of
roadways is to ensure that there is the ability to adequately observe an
obstruction in the road and to safely stop. This is controlled by the ability
to see over the top of a “crest” vertical curve and for the headlights to see
past the low point of a “sag” vertical curve.
15.C Planned Unit Development Compliance Review

Page 13 of 28
K-Values are assigned based on the design speed and associated Safe
Stopping Sight Distance. The genesis for most K-Values used in design in
the past 70 years is from A Policy on the Geometric Design of Highways
and Streets published by the American Association of State Highway and
Transportation Officials (AASHTO) (Exhibit I - AASHTO High Vol Geom. Stds
- Abridged). In 2001 AASHTO recognized that these standards, initially
published in 1954 and subsequently revised and improved upon, had
created a conflict with the unique conditions associated with very low
volume roads (<400 vehicle trip ends per day). They found that the lower
volume roads had lower crash rates and when applying the higher volume
road standards to low volume roads, it had created a “less cost effective”
design solution.
In 2002 AASHTO published the Guidelines for Geometric Design of Very-
Low Volume Local Roads (ADT <400) (See J - AASHTO GeoDesign of V-Low
Vol. Rds – Abridged). The ASHTO Highway Subcommittee on Design
which included over 100 individuals from across the country, including two
from Vermont, developed the more case sensitive and appropriate design
standards for low volume roadways.
Of the 11 design standards set forth in the Public Works Standards, the
applicant has adopted 8 of those and is seeking acceptance of alternate
design values most appropriate for the unique conditions associated with
this application for three (3) of those 11. These are outlined below.
Crest Vertical Curve K-Value of 7 - This value is taken directly from the
AASHTO Low Volume design guidelines (Exhibit J - AASHTO GeoDesign of
V-Low Vol. Rds – Abridged). The K Value identified in the Public Works
Standards is associated with the AASHTO guidance for high volume
roadways (Exhibit I - AASHTO High Vol Geom. Stds - Abridged)).
Sag Vertical Curve of 13 – The sag vertical curve occurs at the far east end
of the road where there is only one home. The design speed here will be
closer to 15 MPH as one prepares to make the turning movement into the
driveway. In the future, if this road is extended to the south, this will
likely be a stop condition intersection. Under either scenario, the design
speed will be much less than the 25 MPH allocated for a free flowing
roadway. We are proposing to assign a design K-Value of 13 for this sag
vertical curve. This is greater than the design K-Value of 10 for a 15 MPH
design speed found in the High Volume road design standards. The K-
Value of 13 also represents the lowest K value which would be associated
with maintaining comfort at the design speed of 25 MPH (See Exhibit K -
Comfort in Sag Vertical Curves). The K Value identified in the Public

Works Standards is associated with the AASHTO guidance for high volume
roadways.
Stopping Sight Distance of 115 feet – This plays into the associated K
Values recommended by AASHTO for Very Low Volume Roadways. The
stopping Sight Distance value identified in the Public Works Standards is
associated with the AASHTO guidance for high volume roadways.
b. Achieves the intent of the PUD standard to be modified; The intent is to
provide a safe roadway under the design conditions. The proposed use of
design guidelines better associated with the conditions still achieves the
intent of providing a safe roadway.
c. Results in development that is equivalent or demonstrably superior in
function, design, and quality to that required under the standard to be
modified; and A downside of designing low volume roadways with high
volume design standards is that the comfortable rate of speed increases
which reduces the traffic calming features originally intended in the
Neighborhood Street typology. The proposed use of the Very Low
Volume Design standards for this extra low volume roadway provides a
better assembly of design and function with the proposed conditions.
d. Does not adversely impact properties, uses or facilities within, adjacent to,
or in the vicinity of the planned development (e.g., regarding walkability,
traffic, parking, drainage). The DRB in approving an alternative form of
compliance may attach conditions as necessary to ensure compliance, or to
mitigate any adverse impacts resulting from a proposed alternative. The
proposed use of appropriate design standards provides a significant
benefit of improved traffic calming (reduced travel speed, increased
safety) for those properties inside the PUD. By the nature of the issue,
there will be no impact on properties located outside of the PUD.
D. Development Density.
i. Intent. A Planned Unit Development is intended to accommodate within a
designated Development Area typically higher effective densities of
development than the underlying zoning district may allow, as necessary to
accommodate:
a. The clustering of development to conserve resources identified
for protection;
b. A more efficient and cost-effective use of land, facilities,
services, and infrastructure;
15.C Planned Unit Development Compliance Review

Page 15 of 28
c. Densities that support a walkable, pedestrian-oriented pattern
of development; or
d. Transit-supportive densities of development along existing and
planned transit routes.
ii. Within a PUD, the overall density and intensity of development shall be
determined based on the total Buildable Area (8.35 Acres) included within
designated Development Areas (10.05 acres – 1.00 Acre Civic Space), as shown
on the PUD Master Plan; and land use allocations, PUD density and dimensional
standards, and allowed building types and standards as specified by PUD type.
iii. Buildable Area. The “Buildable Area” within a PUD is as defined under
15.A.11(2) to include the total tract area, less the area occupied by the following
physical and legal site limitations or constraints:
a. Known Hazards, as defined and regulated under Article 12,
including Floodplain overlay districts A, AE, A1-30, and 0.2% B2

none of these features on the property other than the planned
rights-of-ways for the streets associated with this project
which totals 1.01 acres; and
d. Transmission line corridors or easements Transmission line
corridors, except upon request of the applicant that it be
designated as Buildable Area There are none of these features
on the property.
iv. Land Use Allocations. The Land Use Allocation is defined as the minimum
percentage of Buildable Area within one or more designated Development
Areas, that must be allocated to a particular category of land use, as indicated
on the PUD Master Plan and delineated on preliminary and final subdivision
plans. These include the following use categories, as specified by PUD type:
a. Residential – intended to accommodate allowed residential
uses, including a variety and mix of housing types, associated
15.C Planned Unit Development Compliance Review

building lots, and onsite or shared residential parking areas.
(7.53 Acres or 74.9%)
b. Mixed-Use – intended to accommodate a mix of compatible
residential and nonresidential uses and building types,
associated building lots, onsite parking areas and separately
designated principal or shared parking lots or facilities serving
the development. Lot 1B (1.52 Acres or 15.1%)
c. Civic Space – intended to accommodate one or more civic
spaces, including associated civic space lots and parking
areas.(1.00 Acres or 9.95%)
d. Resource Land – intended to accommodate Hazards and Level I
Resources regulated under Article 12, and other natural or open
space areas included within delineated Conservation Areas or
conservation lots. (Included in civic space area, and spillover
into residential lots)
e. Unallocated – intended for allocation by the applicant under
one or more of the above use categories as allowed by PUD
type, to provide some flexibility in determining the overall mix
of proposed development. This may also be designated on the
PUD Master Plan as unallocated “Reserved” land subject to
reallocation under an approved master plan amendment. None
Proposed.
v. Minimum (Base) Density. To ensure densities of development that support the
efficient use of land and infrastructure, walkability, and transit-supportive
development within a PUD, the following minimum residential densities of
development (Base Density), expressed as the minimum number of dwelling
units per acre of Buildable Area, apply within designated Development Areas
proposed for residential or mixed-use development, unless otherwise specified
by PUD type:
a. The minimum (base) density of residential development within
a designated Residential or Mixed-Use Area, as specified by PUD
Type, represents the minimum number of dwelling units per
acre (DU/A) that is either required or allowed by right under
these Regulations, over one or more phases of development
under an approved PUD Master Plan.
b. The required minimum (base) residential density within a
designated Residential Area is four dwelling units per acre (4
DU/A) or the maximum residential density allowed within the
underlying zoning district (1 unit per 3 acres, modified to 5
units per acre), whichever is greater, except within a Southeast
Quadrant (SEQ) subdistrict. In the SEQ, the minimum (base)
residential density is 4 DU/A.
15.C Planned Unit Development Compliance Review

Page 17 of 28
c. Within a designated Mixed-Use Area, or within ½-mile of a
transit route as shown on Overlay District Map 2 The property
is not located within a designated transit route), the required
residential base density is eight dwelling units per acre (8 DU/A)
or the maximum residential density allowed within the
underlying zoning district, whichever is greater.
d. The residential base density may also vary by subzone, as
specified by PUD type, in association with allowed housing types
within that subzone. No subzone’s are proposed.
e. Accessory Dwelling Units (ADUs) shall not be included in the
calculation of residential base density or the minimum number
of required dwelling units (residential yield). Acknowledged.
f. The minimum number of dwelling units required or allowed by
right (residential yield) within a designated Residential or
Mixed-Use area, excluding ADUs, may be calculated as:
Total Buildable Area (10.05 Acres) x Land Allocation (74.9%
+15.1%) x Base Density (DU/A) 5 units/Acre = Min DUs (45.2)
vi. Nonresidential Base Density. There is no minimum (base) density or intensity
requirement for nonresidential development within a designated Development
Area. Acknowledged.
vii. Maximum Development Density. The maximum development density allowed
within any PUD except a Conservation PUD shall be determined based on the
total buildable area, proposed land use allocations by use category, the allowed
mix of building types, and associated building lot standards as specified by PUD
type.
a. The DRB may allow for an increase in the overall density of residential
development within a designated Residential or Mixed-Use area, for
example through adjustments or modifications to the required housing mix,
allowed housing types, or associated building lot or height standards, as
necessary to accommodate the following None of this is proposed:
i. The purchase and transfer of development rights from land within
designated sending areas under Article 19 Transfer of Development
Rights.
ii. The incorporation of offset housing units under inclusionary zoning
(Section 18.01 Inclusionary Zoning).
iii. The incorporation of additional housing units awarded as an incentive
for affordable housing development under Section 18.01 Inclusionary
Zoning).
iv. The transfer of residential development density within a Conservation
PUD from Level I and other resource or open space areas identified for
protection that are included in a designated Conservation Area.
15.C Planned Unit Development Compliance Review

Page 18 of 28
v. Within a Conservation PUD the maximum residential development
density within the designated Development Area shall be capped as
specified by zoning district under Section 15.C.05.
E. Transition Zone. A PUD may also incorporate one or more transition zones along PUD or
property boundaries, as indicated on the PUD Master Plan and delineated on preliminary and
final subdivision plans, to include the minimum land area necessary to either extend and
integrate compatible, complementary forms of planned Total Buildable Area (A) x Land
Allocation (%) x Base Density (DU/A) = Min DUs (#) development, or to separate and buffer
conflicting, incompatible forms of planned development, in relation to existing and planned
development in the vicinity of the PUD. A Transition Zone is not proposed.
a. The “Transition Area” for purposes of analysis, must at minimum incorporate the
prevalent pattern of development directly adjacent to and within the vicinity of the
PUD, including the relative layout, type and density of existing and planned
development (e.g., street, block and lot configurations, building placement and height);
existing and planned transportation and infrastructure connections; traffic patterns;
public facilities and services; and civic space, resource land and other designated open
space areas located within one-quarter to one-half mile of PUD boundaries, depending
on the development context.
b. Acceptable design techniques and modifications applied within a Transition Zone,
subject to DRB review and approval, include but may not be limited to:
i. Avoiding incompatible land uses along PUD boundaries, for example by ensuring
that similar, or compatible, complementary uses are located on facing blocks or
lots, and incompatible uses abut rear lot lines or are otherwise separated by
buffers or open space.
ii. Using existing natural features, such as changes in topography, waterways, or
tree stands to visually screen or functionally separate different forms and
intensities of development.
iii. Modifying street and block dimensions and standards as necessary to connect
with or to extend adjoining street, block, and path networks.
iv. Using streets and streetscape elements to visually define transitions and to
functionally integrate or separate different forms and intensities of
development.
v. Matching the relative density or intensity of adjoining development along PUD
boundaries by adjusting or averaging lot dimensions (frontage, depth); building
orientation and spacing (front, side setbacks); or building height (step downs,
upper floor step backs) within the transition zone.
vi. Introducing and designing civic or other open space areas (e.g., greenbelts,
parks, greens, squares, or plazas) to visually define transition areas, and to
functionally integrate or separate different forms and intensities of
development.
vii. Incorporating greenbelts or vegetative buffers and screening of sufficient width
and density to visually and functionally separate incompatible forms and
intensities of development.

F. Allowed Uses. Allowed uses within a PUD, unless otherwise expressly allowed or prohibited by
PUD type, include any use listed in Appendix C as a permitted or conditional use in the
underlying zoning district(s) that can be accommodated within, or in association with,
designated land use allocations and allowed building types. Acknowledged
i. Conditional uses allowed within the underlying zoning district shall be considered permitted
uses within a PUD. Separate conditional use review and approval shall not be required.
Acknowledged
ii. Given the emphasis on compact, walkable forms of residential and mixed-use development
within a PUD, auto-oriented uses, building types, and facilities, including uses that require
expansive onsite parking, are generally precluded from locating within a PUD, unless
specifically designed to emphasize a pedestrian scale and orientation of development
fronting on and accessed from the adjacent street, for example by locating shared parking
facilities to the rear of the building, as accessed from a side street. New drive-through
facilities are prohibited from locating within a PUD. Acknowledged.
G. PUD Dimensional Standards. PUD dimensional standards, where applicable by PUD type, define
a range of block, lot, and building height dimensions which are intended to provide, within
defined parameters, some flexibility in the overall pattern of development specific to each type.
Where PUD standards vary from associated building type standards, the upper and lower PUD
dimensional limits (maximum and minimum) limits shall apply. The proposed PUD standards
are outlined below.
30’ Front Yard Setback
10’ Side Yard Setback
20’ Rear Yard Setback (this fronts a commercial property will no active uses near the
common property line)
15’ Accessory Setback (5’ for existing structures)
20% Building Coverage
40% Lot Coverage
Maximum Building Height as outlined in Table C-2 for the R4 Zoning District
H. Street, Building, and Civic Space Types. Where applicable, PUD types include a list of allowed
“types” of development, representing the key elements or components necessary to support
and achieve the desired form, density and mix of development specific to that PUD type. These
include allowed:
i. Street Types, and associated street standards, under Article 11.A; The
Neighborhood Street – Narrow is proposed with this application.
ii. Civic Space Types, and associated civic space and lot standards, under Article
11.B; and A Community Garden is proposed with this application.
iii. Building Types, and associated building and building lot standards, under Article
11.C. Not applicable for General PUD.

I. Solar Siting Preferences. - Applicants are encouraged to incorporate renewable energy
facilities, and in particular roof- or ground mounted solar energy facilities that are compatible
with PUD layout and design, as specified by PUD type. Any areas reserved for ground mounted
solar installations serving the development must be indicated on the PUD Master Plan and
depicted on preliminary and final subdivision plans. No specific dedicated ground mounted PV
Panel installations are proposed to serve the community. An existing PV Panel array occupies
the northeast quadrant and will remain with this project.
J. PUD Design Standards. A proposed PUD must also incorporate and comply with design
standards specific to that PUD type, except as allowed in association with a form of Alternate
Compliance approved by the DRB under 15.C.04(C). Acknowledged.

the interest of brevity
15.C.07 General PUD
A. Authority and Limitations.
(1) The Development Review Board (DRB) has the authority under 24 VSA § 4417 to review, to
approve, to approve with modifications and conditions, or to disapprove an application for a
Planned Unit Development (PUD), as further described in Section 15.C.01.
(2) Limitations on DRB authority under 14.04(A)(3)(b) apply.
(3) In addition, in no case shall the DRB vary:
(a) Density restrictions and/or allow an increase in overall density except as authorized via use of
Transferrable Development Rights or via Inclusionary Zoning. No proposed increase in
maximum residential density if proposed.
(b) Requirements of the Urban Design Overlay District and Transit Overlay District, as applicable
Not applicable for this project.
(c) Applicable lot coverage and/or building coverage maximums allowed within each zoning
district, as measured across the PUD as a whole, except as authorized via use of Transferrable
Development Rights. The proposed lot coverage limitations are being borrowed from the R4
District and are 20% for Building Coverage and 40% for Lot coverage.
(d) Environmental Protection Standards under Article 12, except as authorized within that Article.
Acknowledged.
(e) Parking and building location requirements in Section 14.06(A)(2), except as authorized within
that Section. The DRB is asked to allow for parking in the front yard (in front of buildings) as
permitted for single family homes.
B. General PUD Description, Purpose, and Characteristics. A General PUD is a type of planned
development that allows for relief from the strict dimensional standards for individual lots in order to
encourage innovation in design and layout and efficient use of land consistent with the Comprehensive
15.C Planned Unit Development Compliance Review
WGM Associates, Inc.
April.23, 2024
Page 21 of 28
Plan. Defining characteristics of a General PUD include well planned, -sited, and -designed development
projects that:
• Conform to the goals in the City of South Burlington Comprehensive Plan and South Burlington City
Council’s Resolution on Climate Change dated August 7, 2017. The project proposes to create new
infill residential development within the I-O District in a manner that balances the applicant’s goals
and the density goals of the I-O District.
• Support and enable affordable housing development. The applicant proposes through the
Alternative Compliance review process how a housing development can be made more affordable.
• Contribute to the City’s economic vitality, in response to changing markets and consumer demand,
by providing needed housing, goods, services, and employment opportunities. This proposed
project will create opportunities for the family members to remain in place.
• Redevelop underperforming properties and commercial strips (retrofits), contaminated sites
(brownfields), and large expanses of parking (gray fields) into more compact forms of walkable,
pedestrian-oriented, mixed-use development. Not applicable.
• Extend or re-establish existing street, sidewalk, and recreation path connections. The low density
of this project seeks alternate compliance with the consolidation of the bicycle and pedestrian
facilities.
• Incorporate a density of development that supports walkable residential, mixed-use, and transit
oriented development, compatible in design with the surrounding area. The project site is located
outside of a mixed use transit designated development and proposes to create a neighborhood
which consolidates the supporting infrastructure in an environmental and economic manner.
• Improve the physical appearance, walkability, and amount of civic and green space within existing
residential neighborhoods, commercial centers, and commercial strip development. The property
currently hosts three residential homes and numerous accessory structures. Due to the layout of
the buildings they enjoy a safe walkable environment that is proposed to be extended along
primarily the northern half of the property.
• Introduce missing or complementary uses, facilities, services, amenities, or civic space intended to
serve the immediate and surrounding area. The project proposes the introduction of a formally
dedicated civic space not present on the property today.
• Foster context-sensitive transitions among and between neighborhoods, commercial areas, mixed
use areas, civic spaces, and natural resource areas. This project and its modest density seeks to
strike a balance between the creation of new residential lots while recognizing and blending with
the large open space areas that surround the existing commercial and light industrial uses in the
area.

C. Applicability. A General PUD is an allowed PUD type in the following circumstances:
(1) Within the underlying zoning districts listed in Table 15.C-1 for General PUD The I-O District is
identified as being able to host General PUDs..
(2) For amendments to General PUDs approved under this Section. Not applicable.
(3) For minor amendments to existing PUDs reviewed and approved under the LDRs in effect until
November 10, 2021, the final subdivision approval for which has not expired, regardless of zoning
district. Not applicable.
(a) An amendment shall be considered “minor” if it does not significantly alter the overall intent or
scale of the PUD, or the relationship of the approved PUD to its surroundings. A minor
amendment may incorporate additional land not in the PUD as previously approved, but only to
the extent that the additional land does not cause the PUD to exceed other requirements of this
section.
D. Conformance with PUD Standards. In addition to the specific standards under this Section, all
standards in Section 15.C.04 shall also apply Acknowledged. Responses are provided within that
respective section. Application and review process for a General PUD is governed by Section 15.C.03.
E. Context. For planning and design purposes, “Planning Area” is defined as the area within ¼-mile of the
lot or parcel to be developed, as measured from the lot line or delineated PUD boundary.
Acknowledged. This is the same group of abutters notified for the Neighborhood Meeting.
F. General PUD Compatibility and Context Analysis.
(1) Compatibility. PUD compatibility with the Planning Area, as determined from a detailed analysis of
the Development Context, shall be a primary consideration in General PUD project design, and for
DRB review and approval.
(2) “Development Context” is defined to include:
(a) The prevalent or recurring pattern and form of development within the Planning Area, including
established street grid None to speak of and streetscape elements Street trees would be the most
common, blocks None, lots Large (3-acrees and larger), buildings medium to large buildings
and yard areas Often large green space area to offset the 50% maximum lot coverage
consumed by the building and parking lot footprints, civic spaces minimal, and parking
arrangements Typically large parking lots, and
(b) The character of the Planning Area, as defined by:
(i) The planned character of an area planned for redevelopment by the City as identified in the
Comprehensive Plan; This is identified as Commercial-Industrial with Supporting Uses
which residential development is a component of this area.
(ii) Approved, to-be-built or recently built (within ten (10) years) development projects in the
Planning Area; The only activity in the past 10 years has bene the creation of the Doggy

(iv) Zoning district purpose statements, allowed uses, and district-specific development
standards. No specific development standard changes have been implemented for the I-O
District beyond the requirement to integrate amenity areas.
(c) Current zoning purpose statements, uses, and standards only if the DRB finds there is no
relevant information under 15.C.07(F)(2)(a) or (b)(i) through (b)(iii), or the DRB finds that there
is a clear, established neighborhood street, block, and lot pattern. Lacking positive findings
for the three sub-items, inserted below is the purpose statement for the I-O District.
A. Purpose. The Industrial-Open Space IO District is established to provide suitable locations for
high-quality, large-lot office, light industrial and research uses in areas of the City with access to
arterial routes and Burlington International Airport. The IO District regulations and standards
are intended to allow high-quality planned developments that preserve the generally open
character of the district, minimize impacts on natural resources and water quality, and enhance
the visual quality of approaches to the City while providing suitable locations for employment
and business growth. The location and architectural design of buildings in a manner that
preserves these qualities is strongly encouraged

G. General PUD Dimensional Standards.
(1) Relevant subdivision, site plan, zoning district, and applicable overlay district dimensional
standards shall form the basis of the design of a General PUD and shall apply unless modified,
reduced, or waived by the DRB under (2) below. The general proposal is to adopt the slightly
modified R4 dimensional standards including lot and building coverage and heights.
(a) The DRB must find an application meets the requirements of 15.C.07(G)(2) in order to modify,
reduce, or waive Site Plan requirements using 14.04(A)(3), Site Plan application requirements
using 14.05(G), Subdivision requirements using 15.A.01(B)(3), Scenic Overlay District
