Application for Amendment 2 of 30
SECTION I
15.B.04(B) – PROJECT DESCRIPTION
As outlined in LDR Section 15.B.04(B), the Project Description section shall address the following items:
• Overall vision for and scope of the proposed development
• The land area and properties to be included under each phase of development
• Current property ownership contact information
• Current zoning district designations
• Proposed PUD types
• Project consistency with applicable zoning and subdivision regulations
• Any requested modifications or waivers, as allowed under these regulations
Overall vision for and scope of the proposed development.
BETA is proposing to redevelop approximately 40.43 acres of underutilized brownfield property (South 40
Campus/S40), located at the southern end of the Burlington International Airport (BTV), into an
environmentally sustainable state-of-the-art campus for manufacture and assembly of the company’s
electric aircraft. The campus is planned to include a manufacturing facility, general aviation hangar, training
and cultural center, mixed office/retail building, and a childcare facility – all underpinned by open space
and designed for interconnectivity via new roads and pedestrian paths.
The S40 campus is intended to become a community asset that will promote a growing acceptance of an
interest in electric aviation and transportation by making it accessible to a wide spectrum of people from passionate aviators to individuals curious to learn more about the systems that are transforming their day-
to-day lives.
By redeveloping this property into an open campus, we hope to enable cross-pollination of opportunities
between the buildings and across the campus – as well as between the BETA team and the broader
community. We envision this space will stimulate shared opportunities for learning, community events, and
other shared local functions.
The land area and properties to be included under each phase of development.
Buildout of the campus master plan will occur over multiple phases, with the possibility of more than one
project overlapping with another. BETA has submitted for and received its zoning permits for the
Manufacturing and Assembly Facility Phase I (A-Build) and the General Aviation Hangar (GAH) projects –
both of which are currently under construction.
BETA has also submitted an application for amendment, SP-22-056, to add 261 parking spaces at 154 Da
Vinci Drive. This application has been continued by the DRB to February 7, 2023, pending approval of this master plan amendment.
Follow on projects are planned to include:
• Construction of the next phase of the aviation cultural center which will include flight training
facilities, simulators, an aviation-inspired café, and other spaces to facilitate excitement and
learning around aviation. The project will be Phase II of the GAH project currently under
construction.
Beta Technologies Master Plan (MP-21-02) January 12, 2023
Application for Amendment 3 of 30
• Construction of a new mixed-use office/retail building along Williston Road (to replace the existing
3060 Valley Drive building), expanded parking and new solar farm;
• Construction of a new childcare facility to support BETA employees and their families.
Development of the campus includes one parcel in the AIR-I district and four parcels in the IC district. The IC
district parcels, shown in green below and in SP-001 – EXISTING SUBDIVISION PLAN, will be consolidated
into a single parcel once fully built out. Additionally, consolidation includes dissolving multiple lease lines
and easements.

Final parcel configurations after consolidation of lots and easements are shown below and on sheet MP-
002 – FINAL PLAT REVISION & LOT CONSOLIDATION PLAN.
Current property ownership and contact information.
Each of the parcels required for this master plan are owned by the City of Burlington / Burlington International
Airport. Inquiries should be directed to:

Beta Technologies Master Plan (MP-21-02) January 12, 2023
Application for Amendment 5 of 30
Current zoning district designations.
The proposed development spans two zoning districts within the city. The Manufacturing Facility and Cultural Center projects are located within the Airport Industrial (AIR-I) district. While the proposed mixed-use commercial building and future childcare facility are within the Mixed Industrial & Commercial (IC) district. Both zoning districts support a
variety of by-right uses that are consistent with those in the master plan.
Proposed PUD types.
Not applicable; this master plan application does not include a PUD.
Project consistency with applicable zoning and subdivision regulations.
The proposed Master Plan amendment is consistent with both the applicable zoning and subdivision regulations
(15.A – SUBDIVISION REVIEW).
No changes to the Final Subdivision Plan and or Plat Plan from the previously approved Master Plan are requested.
Any requested modifications or waivers, as allowed under these regulations.
Parking. This amendment requests modification of the previously approved onsite parking layout as allowed by 14.06(A)(2)(b)(viii) to construct “parking between a public street and one or more buildings”, as “the
building, or a portion thereof, being served by the parking area is contained with the Security Identification
Display Area (SIDA) of a publicly-owned and operated airport.”
Beta Technologies Master Plan (MP-21-02) January 12, 2023
Application for Amendment 6 of 30
As shown below, the northeast elevation of the building is co-planar with the SIDA line (blue dashed line)
eliminating the ability to “locate the parking to the rear or sides of the building(s).”
Master Plan Duration. BETA is seeking to maintain the previously approved MP-21-02 Condition #10, as
shown below, which would then require the DRB to grant an extension as allowed under 15.B.06(D)(4) –
MASTER PLAN DURATION extension provision.
MP-21-02 Decision Condition No. 10 as written:
“This master plan shall expire in 10 years if final applications (final plat or site plan, as required) for development of each of the phases identified herein have not been submitted in that time. There
shall be no required timelines within the 10-year period.”
To apply this provision, the Applicant must show “cause” for the request. As discussed during the prior DRB
hearings (Hearing No. 1 – 12/21/21; Hearing No. 3 – 2/15/2022), the 10-year duration was requested to
accommodate both BETA’s business needs and regulatory/market dynamics.
From a business perspective, the 10-years allows BETA to migrate from a research and development
company into a manufacturing company during which time the assembly process will evolve from manual
or hand-built articles to articles built with some level of automation. How much and or what type of
automation is not currently known and will be developed in a “crawl, walk, run” model as the
manufacturing and assembly processes develop over time.
Beta Technologies Master Plan (MP-21-02) January 12, 2023
Application for Amendment 7 of 30
Similar to the business needs, establishing a 10-year master plan allows BETA to remain nimble and
respond to the inevitable shifts in regulatory requirements and or market dynamics. The FAA has yet to
establish clear guidance on the final envelope which the aircraft must operate in. As these guidelines
become clearer, there will be changes to the plane which will require changes to the manufacturing and
assembly process ultimately impacting the timeframe for the remaining phases.
Providing a 10-year master plan duration provides for the opportunity to take the time to understand the
requirements for the follow-on phases. To be able respond to the business and regulatory/market needs,
BETA requests that the previously approved condition remain as written.
MP-21-02 Decision Condition No. 6a. BETA requests that the previously approved condition be maintained
allowing BETA to proceed directly to site plan review for applications which are consistent with the plans
presented at master plan and do not involve subdivision of land.
MP-21-02 Decision Condition No. 6b. BETA requests that the previously approved condition be maintained
allowing BETA to proceed directly to zoning permit approval for the following items:
• PV Solar Equipment
• Battery Backup Equipment
• Assembly Process-related Equipment
• Utility Transformers, Pedestals, and associated appurtenances
• Electric Aircraft and Car Chargers
If they conform to the following limitations:
a. A maximum equipment height of 15-ft.
b. Located where fully screened from Williston Road and Eagle Drive and where set back at least as far
as the nearest adjacent building from the central access drive.
c. Equipment must fully comply with the performance standards of LDR Appendix A. These
performance standards set numeric standards for vibration, noise, and air pollution amongst
others.
Equipment shall be directly related to the approved use of the building to which it is adjacent.
MP-21-02 Decision Condition No. 14a. FAR is no longer an applicable standard in the current LDR’s, eliminating the need for Condition #14a.
Building Height: A building height waiver of 5’ from 35’ to 40’ to accommodate a 3-story building as
intended by the LDR’s.
• The intent of the LDR building height requirement is to allow 3-story buildings. However, the 35’
height requirement for flat roofs is not consistent with current building standards, limiting future
development to a 2-story building.
• Master plan approval is intended to provide the Applicant a predictable road map for planned
future development.
Asking the applicant to request a waiver for each project is inconsistent with the goals of master
plan approval.
Landscaping Budget – applicant requests that when calculating the landscape estimate, that the
actual amount spent on landscaping over the Landscape Budget from previous projects within the
master plan area be applied towards meeting the Landscape Budget. At each phase of
development, an overall budget tracking spreadsheet for the master plan area will be provided.

A more detailed Development Context Analysis as required for an Infill or Redevelopment (IRD) PUD
under Article 15.C, as applicable.
This project is not an Infill or Redevelopment (IRD) PUD and does not require a more detailed Development
Context Analysis.
A description of how concerns raised in the Neighborhood Meeting will be addressed.
A Neighborhood Meeting was not required under the LDR’s that guided MP-21-02, effective 28DEC20.
This requirement is not applicable, as MP-21-02 was appealed by the Applicant to the State of Vermont
Environmental Court and remanded to the South Burlington Development Review Board. Since the project
has proceeded beyond the Neighborhood Meeting phase, and as guided by Planning and Zoning staff,
review of this application will begin at 15.B.04.

A maximum of 539 peak hour trips to account for 5% increase in calculated trips (513) to allow minor future
modifications to the development program without requiring master plan amendment. See attachment 001
– TRAFFIC IMPACT STUDY for additional information.
Maximum water supply and wastewater system demand, by use type.
Calculation for future water supply and wastewater system demand has been reviewed by City staff. See
attachment 002 – WASTERWATER-WATER ALLOCATIONS for additional information.
Maximum total impervious surface (percentage, total square footage), and volume of stormwater runoff
per designated Development Area.
Per Section 13.05 of the LDR's, the project will treat the water quality volume from all redeveloped and new
impervious on-site and detain the 1-year 24-hour storm event. While it is preferred to infiltrate stormwater
runoff, the geotechnical analysis indicated poorly draining soils within the proposed master plan area. Each
site will utilize practices that recharge ground water to the maximum extent feasible but will rely on
filtering practices to provide treatment and detention for the 1-year storm including bio-retention basins,
sand filters and gravel wetlands. Further geotechnical investigations will occur during future phases of
development to further assess the feasibility of infiltration basins and trenches.

Class II wetlands exist along the proposed Da Vinci Drive. These wetlands were delineated by a wetland
specialist on 5/18/2021 and reviewed with the Vermont Department of Environmental Conservation
District Wetland Ecologist on 7/6/2021. Impacts to the wetland and buffer are associated with the removal
of an existing gravel road and slope impacts, both restored with topsoil, seed, and mulch. During
construction, the wetland and wetland buffer will be protected from sediment and erosion via woven wire
silt fence and snow fence. A General Wetlands permit (16451-C-4061-22.0) has been issued for the

Parking standards and specifications for off-site, on-street, and on-site parking, including any charging stations needed to serve proposed development, consistent with City parking standards under Section
13.01, Article 14, and by Street Type.
Parking. Parking for each of the proposed buildings will be as outlined below:
Cultural Center. Cultural center parking will be adjacent to the proposed building, accessed from Eagle
drive and the Da Vinci Drive.
Commercial, Childcare, and Assembly Buildings. Parking for the commercial building, childcare building,
and assembly facility, will be shared amongst each use.
Parking Demand. The number of parking spaces required for each phase of development will be determined based on building use through a combination of the ITE Parking Generation manual and an
independent analysis that assesses the effect of vehicle reduction strategies such as staggered shifts,
carpooling, bicycle commuting, walking, transit use and telecommuting.
Electric Vehicle Charging. BETA’s electric vehicle (EV) charging goal is to have a 10% of total parking spaces
with EV charging dispensers and at minimum meet the requirements for EV charging specified in the
Vermont Commercial Building Energy Code Standards (CBES). For this type of development, the CBES
requires 3% of total parking spaces to have electrical vehicle charging and 3% to be pre-wired allowing for
future EV supply equipment installation. BETA has far exceeded this standard for the two projects currently
zoned for construction, providing approximately 10% of parking spaces with EV charging dispensers.
Setbacks, buffering, screening, or other mitigation measures necessary to separate incompatible land
uses, particularly within designated transition areas.
N/A; the development neighbors compatible industrial commercial land uses.
Overall lighting plan, including typical fixtures, consistent with relevant lighting requirements under
Section 13.07 and Appendix D.
Site lighting will utilize pole-mounted fixtures for driveways and parking areas. Building mounted lights to
be provided at the required footcandle levels to support operations and life safety needs around the
building. All exterior lighting will be light emitting diode (LED) fixtures that are full cutoff, dark-sky

Application for Amendment 23 of 30
compliant and designed to not interfere with airport lighting. Lighting will be controlled by a 365-day
astronomical time clock and the pole lights will have integrated high/low motion/ambient sensors. All
fixtures to be DesignLights Consortium (DLC), energy star or equivalent rated. See attached, LIGHTING CUT
SHEETS for typical fixtures. Plans showing the location of light fixtures and the lighting levels will be
submitted during site plan review for each development.
Conformance with LDR’s:
• Maximum fixture height is thirty (30) feet with the exception for Federal Aviation Administration
(FAA) required lighting.
• Full cut-off lights fixtures proposed.
• Illumination levels at ground level to be less than a three (3) footcandles average. To safely conduct
nighttime activities, occupancy sensors will be installed to temporarily increase lighting levels
during those activities.
• Indirect glare produced by illumination at ground level to not exceed 0.3-footcandles maximum,
and 0.1-footcandle average.
Landscaping and screening specifications, consistent with relevant landscaping standards under Section 13.04.
The Beta campus strives to locate functional spaces, designed to meet the requirements of the technology
in production, practically and efficiently within a larger humane and biophilic campus environment that
emphasizes routine exposure to the natural world. Architecture orients towards views of the Vermont
landscape and orchestrates flows of natural light and air as well as human collaboration and camaraderie.
Sites are accessible, resource-conscious, and densely-planted with predominantly native species, allowed to
grow naturally – a campus within a microcosm of the Vermont forest/field landscape.”
Projects within the master plan area meet the requirements of the LDR's, Section 13.04 Landscaping,
Screening, and Street Trees, including but not limited to:
• Over 10% of the interior of the parking lot will have landscaped islands planted with trees.
• Interior and perimeter plantings will be protected by curbing.
• Trees to be provided within or near the permitter of the parking area with at least one (1) tree for
every five (5) parking spaces.
• Snow storage areas will avoid stormwater treatment practices and be reviewed by maintenance
staff to confirm location and size is sufficient. These locations will be defined and reviewed during
the site plan application process for each development.
• Landscaping Budget – each project will submit an individual landscaping estimate for each phase of
development to include cost of trees; shrubs; decorative grasses; amount spent on landscaping
over the landscaping budget from previous projects within the master plan area; decorative
hardscape elements above the cost of concrete; and public art. At each phase of development, an
overall landscaping budget tracking spreadsheet for the master plan area will be provided.

Application for Amendment 24 of 30
Specifications for the siting and design of new buildings, and the retrofit of existing buildings, as
necessary to meet applicable energy standards under Section 3.18, and to incorporate renewable energy
installations.
In keeping with the City’s Comprehensive Plan and BETA’s values, sustainable design strategies have been
applied across the campus master plan. Projects within the master plan will meet the commercial building
energy standards (CBES) including Appendix CA – Solar-ready Zone - Commercial.
Energy Goals. Proposed buildings will be designed to minimize their respective footprints and impact on the
environment by utilizing high-performance building envelopes, geothermal systems, rainwater harvesting
and stormwater treatment strategies, and solar PV arrays enabling the buildings to operate with no fossil
fuels and limited impacts. Additionally, power needed to operate the facilities beyond that generated by
the solar PV will be provided by GMP, whose power is generated through 100% renewable sources.
Holistic Sustainability. Beyond its energy goals, BETA is exploring holistic sustainability criteria, including
low-impact development (LID) strategies for land management (reduced stormwater runoff and heat island
reduction), reduction of potable water through efficient fixtures, materials that promote reduced life cycle impacts, locally sourced goods, and services, and along with optimizing indoor air quality.
Other Goals. This project includes additional measures, which link to sustainability targets, including long-
term climate change adaptability and the use of evidence-based design approaches to promote mental and physical wellbeing for staff and visitors. These include but are not limited to outdoor places of respite,
designing for physical activity, and access to daylight and natural views.
Any additional architectural or design guidance for each type or phase of development, and for proposed
transition areas, that is intended to integrate existing and new forms of development, and to ensure
coordinated and cohesive phased development.
Development Context and Form. The new buildings will be designed to create a holistic campus yet retain
the ability to have each building reflect its independent function and use while being part of a greater
whole. The new buildings throughout the campus will be unified by a consistent design palette that is
reflected in:
• exterior materials and geometries
• a focus on high-performance sustainable design
• a commitment to enhancing the human and pedestrian scale
• accessibility
• beauty of the existing airport
• Da Vinci Drive, and Williston Road context.
As this is a new a campus and that the existing buildings will be demolished during buildout, the form of
development will be consistent within the established master plan.

SECTION VIII
15.B.04(I) – PHASING PLAN
As outlined in LDR Section 15.B.04(G), the Phasing Plan section shall address the following items:
• A narrative or table and map that clearly identify, describe, and depict each phase of development,
including properties included, designated development areas by use type, major streets, supporting
infrastructure and facility improvements, civic spaces, and other public amenities to be provided
prior to or in association with each phase;
• A schedule for the timing and sequence of development over the period covered by the Master
Plan, consistent with the City’s adopted Capital Improvement Program and Official Map;
• Each proposed phase of development should account for at least 20 percent of the total project
area or expected buildout in units/square feet; incorporate one or more distinct areas identified for
coordinated development and management; and the infrastructure and facilities necessary to
support that phase of development;
• Any temporary or interim structures or uses (e.g., buildings, parking, construction, or staging areas) intended for conversion or redevelopment in a subsequent phase should also be identified in the
phasing plan.
A narrative or table and map that clearly identify, describe and depict each phase of development,
including properties included, designated development areas by use type, major streets, supporting
infrastructure and facility improvements, civic spaces, and other public amenities to be provided prior to
or in association with each phase.
Buildout of the campus master plan will happen over multiple phases in the coming years, with more than
one project running concurrent with another.
BETA is currently underway on construction of the Assembly Facility (blue phase) and the General Aviation
Hangar (purple phase). BETA will be submitting a Preliminary/Final Plat application for proposed campus
parking in parallel with this master plan application.
Development phases are noted as colors to allow build-out of development to align with business needs
and market dynamics.
Projects within the master plan area to include:
• BLUE Phase. Construction of an assembly facility, apron, geothermal field, parking lot, left turn lane
and access road. The BLUE phase, as previously reviewed, has been separated into a BLUE and
ORANGE phase to reflect the assembly facility will being constructed in two phases. A zoning and
building permit have been issued for this phase, with construction underway and expected to be
completed late fall 2023.
• ORANGE Phase. DRB has issued the Findings of Fact and Decision (FF&D) for this phase of work
which is anticipated to proceed in 2024.
• RED Phase. Construction of a new mixed-use office/retail building along Williston Road (to replace
the existing 3060 Valley Drive building), expanded parking and new solar farm.
• GREEN Phase. Construction of a new childcare facility to support BETA employees and their
families.
Beta Technologies Master Plan (MP-21-02) January 12, 2023
Application for Amendment 26 of 30
• PURPLE (LIGHT and DARK) Phase. Construction of a new general aviation hangar is currently
underway and anticipated to be complete in mid 2023. This hangar will be expanded in the future
to include a cultural center, flight training facilities, simulators, aviation inspired cafe, and other
spaces to promote the wonder of aviation.

Application for Amendment 27 of 30
A schedule for the timing and sequence of development over the period covered by the Master Plan,
consistent with the City’s adopted Capital Improvement Program (CIP) and Official Map.
Timing and Sequence of Development. The schedule below identifies the anticipated timing of development across the phases with the BLUE phase establishing the majority of the infrastructure
required for the follow-on phases.
Capital Improvement Plan and Official Map Alignment. After reviewing the City of South Burlington Capital
Improvement Projects FY23-32, as adopted by the City Council, and the Official Map (effective October 25,
2021), BETA believes that the proposed timing and sequence of development is consistent with both
documents. Water-wastewater and roadway-street impacts are discussed below.
Water-Wastewater Capital Improvements. During the previous master plan review, City Staff and the
Champlain Water District reviewed and approved the wastewater and water allocations suggesting no
capital Improvements are required as part of this development.
Roadway-Street Capital Improvements. The traffic impact study suggests only localized improvements
to the public roadway at the entrance to the site, including a left turn lane and a signal. Additional
improvements include a new bus shelter, bike lanes, sidewalk, utility relocation and street trees. Note
improvements due not require CIP funding.
These improvements are consistent with the City's comprehensive plan and official map that seek to
"implement a series of recommended improvements to US 2 (Williston Road) throughout the City of South
Burlington, including capacity, access management, safety, transit service, intersection improvements,
turning lanes, streetscape, pedestrian and bicycle infrastructure and signalization adjustments."
Beta Technologies Master Plan (MP-21-02) January 12, 2023
Application for Amendment 28 of 30
Each proposed phase of development should account for at least 20 percent of the total project area or
expected buildout in units/square feet; incorporate one or more distinct areas identified for coordinated
development and management; and the infrastructure and facilities necessary to support that phase of
development.
In accordance with section 15.B.04(I)(2) of the LDR’s, each phase is required to be twenty percent (20%) of
the total project area. The support infrastructure and largest building within the project area is built during
the blue phase. For this reason, the subsequent phases do not account for 20% of the total project area.
However, the intent of the rule is still met as the subsequent phases of development are relatively equal in
size and scale and will have the majority of the infrastructure in place to support them.
Any temporary or interim structures or uses (e.g., buildings, parking, construction, or staging areas)
intended for conversion or redevelopment in a subsequent phase should also be identified in the phasing plan.
The existing commercial building at 3070 Williston Road, will continue to be operational until the red phase
is completed. The existing landscape business, commercial garage and small warehouse will be used as field
offices during construction of the blue phase until construction sequencing requires the structures to be
demolished to accommodate the remaining work of that phase.

SECTION IX
15.B.04(J) – MANAGEMENT PLAN
As outlined in LDR Section 15.B.04(J), the Management Plan section shall address the following items:
• A narrative description of the proposed management structure responsible for project
development, to include all principals or entities with direct control over and responsibility for the
financing, permitting, construction, and completion of development under the Master Plan; and,
following project completion, for long-term ownership, management, operation, and maintenance
of capital and community assets.
• The management plan must also clearly identify any streets, infrastructure, facilities, civic or other
open spaces proposed for public dedication under each phase of development, consistent with the
City’s adopted Official Map and Capital Improvement Plan, for consideration under subsequent DRB
review and conditions of approval or under development agreements to be approved by the City
Council.
A narrative description of the proposed management structure responsible for project development, to
include all principals or entities with direct control over and responsibility for the financing, permitting,
construction, and completion of development under the Master Plan; and, following project completion, for long-term ownership, management, operation, and maintenance of capital and community assets.
Project Development Structure. For development of the initial phase of the master plan, BETA is acting as
the development manager on behalf of both BETA and the City of Burlington/Burlington International
Airport (BTV/BIA) and is responsible for directing all project related activities including financing,
permitting, and construction of the assembly facility, general aviation hangar, and associated site
infrastructure.
Development management responsibilities for the balance of the master plan will be determined based on
the specific ownership structure of that parcel/project.
Ownership & Operational Management of Community Assets.
Capital Assets. Ownership of capital assets is divided or allocated between BTV-BIA and BETA with BTV-
BIA retaining infrastructure elements such as the private drive and site improvements that support the
development master plan, and BETA retaining the buildings.
Management, operation, and maintenance responsibilities for these elements follow the ownership
structure.
Community Assets. As described in Section 15.B.04(E) – DEVELOPMENT PLAN above, no community
assets are proposed for public dedication which would then require a management plan.
The management plan must also clearly identify any streets, infrastructure, facilities, civic or other open
spaces proposed for public dedication under each phase of development, consistent with the City’s
adopted Official Map and Capital Improvement Plan, for consideration under subsequent DRB review
and conditions of approval or under development agreements to be approved by the City Council.
No streets, infrastructure, facilities, civic or other open spaces are proposed for public dedication.
