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 Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 3 of 32 learning around aviation. The project will be Phase II of the GAH project currently under construction. • 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. Figure 1: Existing Development Parcels Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 4 of 32 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: Figure 2: Final Parcel Configuration Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 5 of 32 Nicolas Longo, C.M., Director of Aviation 1200 Airport Drive, South Burlington, VT 05403 e: nlongo@btv.aero m: (802) 503-7368 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. Figure 3: Zoning Districts Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 6 of 32 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.” 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.” Figure 4: SIDA Fence Line Location Plan Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 7 of 32 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. 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. Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 8 of 32 • 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. Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 9 of 32 SECTION II 15.B.04(C) – CONTEXT REPORT As outlined in LDR Section 15.B.04(C), the Context Report section shall address the following items: • Existing parcels, and existing and planned streets and blocks, recreation paths, transit routes, buildings, land uses, parks, civic spaces, and other open spaces and community facilities located within 1/4-mile of project boundaries; • Proposed street, recreation path, transit, infrastructure, and open space connections between existing, planned, and proposed development; • A more detailed Development Context Analysis as required for an Infill or Redevelopment (IRD) PUD under Article 15.C, as applicable; and • A description of how concerns raised in the Neighborhood Meeting will be addressed. Existing parcels, and existing and planned streets and blocks, recreation paths, transit routes, buildings, land uses, parks, civic spaces, and other open spaces and community facilities located within 1/4-mile of project boundaries.

Proposed street, recreation path, transit, infrastructure, and open space connections between existing, planned, and proposed development. See sheets MP-003 – CAMPUS SITE PLAN and L-002 – CAMPUS PLAN for the requested information. 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.

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. These allocations are expected to be the maximum throughout the duration. During the first (Blue) phase, three existing buildings are slated to be removed and during the red phase, an existing building will be removed and replaced with a building expected to have similar water supply and wastewater system demand. 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.

Table 9 - Zoning District Dimensional Standard Summary 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.

Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 24 of 32 Overall lighting plan, including typical fixtures, consistent with relevant lighting requirements under Section 13.07 and Appendix D. Designed with BETA’s values in mind, the site and landscape lighting design focus on energy efficiency, safety, and creating an inviting environment. At the building façades, egress man-doors to be provided with exterior wall mounted full cut-off luminaires with emergency power for egress lighting. Throughout the site, various levels of luminaires will be utilized to illuminate areas and pathways. • Site Area luminaires mounted to 25’ poles will be provided for parking lot and drive aisles. • Pedestrian Area luminaires to be mounted to 15’ poles illuminate pedestrian sidewalks. • Pedestrian Pathways luminaires to be bollard-type mounted along pedestrian pathways. Luminaires are located and aimed to direct lighting towards the site and away from adjacent properties. Luminaire types are all full cut-off to minimize spill lighting and glare. Exterior lighting shall be controlled via photocell for dusk-to-dawn operation. Timeclock control will reduce light output in non-essential lighting zones. All fixtures to be Design Lights Consortium (DLC), energy star or equivalent rated. Lighting will be minimized within the parking lot area but used as a site feature around the buildings including: • Recessed architectural lighting at canopies • Architectural accent lighting is provided to emphasize the architectural façade elements at night • Recessed downlighting is also provided to illuminate vertical wood slats • Around the main entries, bench lighting will be incorporated For emergency situations, the system shall be able to override all exterior lighting to “on.” To ensure consistency, light fixtures, light poles and light pole bases have been standardized per the attachment “LIGHTING CUT SHEETS” and will maintain conformance with the standards set by the LDR’s. 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.” Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 25 of 32 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. 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, at a minimum, meet the commercial building energy standards (CBES) including Appendix CA – Solar-ready Zone - Commercial. These measures include, but are not limited to: • Orientating buildings between 110 degrees and 270 degrees of true north • Buildings to have low-slope roofs • Structural design to support additional roof loads • Provide pathways for routing conduit or piping from solar-ready zone • Space will be allocated on the main electrical service panel • Large trees will be positioned so as if to not block sunlight 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. Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 26 of 32 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 Beta Technologies master plan at BTV proposes a total of four buildings to be built over several phases and be sited within a sensitively designed landscape plan. The new buildings throughout the campus will be unified through the use a common material palette (to be supplemented based on building program, type, and use) and geometries, a focus on high-performance sustainable design, and a commitment to enhancing the human and pedestrian scale, accessibility and beauty of the existing airport, Da Vinci Drive, and Williston Road context. 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. To the north, the proposed General Aviation Training Center and Manufacturing Plant buildings are sited along the new Da Vinci Drive and with access to the airport aprons and runways. Each of these buildings will be constructed in multiple phases, and all phases will utilize, but not be limited to, similar rectangular geometries and proportions along with a consistent, appropriate exterior palette of white insulated metal panel walls, black aluminum curtainwall, and translucent polycarbonate panels at airside hangar doors. Both buildings also incorporate photovoltaic panels at their rooftops and, at the General Aviation building, on portions of the elevation, making the sustainable design features of the buildings visible from aircraft arriving and departing from BTV, and from Da Vinci drive. Both buildings include focal elements that highlight their entrances, including increased area of fenestration, canopies, and landscaped open spaces including plantings and hardscaping. At the south edge of the master plan site, along Williston Road, the commercial buildings are well separated from the manufacturing building and the general aviation buildings. As such, these buildings’ scale, materials, and landscaping will reinforce the pedestrian scale and improved streetscape along Williston Road. As with the buildings to the north, the two commercial buildings will share an exterior palette appropriate to their highly visible frontage, high performance sustainable design, plan proportions, and sensitive landscaping. Natural materials at the landscape will nestle the buildings into their street front site, while trees between Williston Road and both new buildings will soften the street edge and enhance the pedestrian routes along Williston and adjacent to the buildings. As with the other buildings on the site, the commercial buildings will include focal elements that highlight their entrances, including increased area of fenestration, canopies, and landscaped open spaces including plantings and hardscaping. 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. Between the two northern buildings and the southern commercial buildings, a landscaped parking area will further unify the entire campus. It does this through a new winding road that links all buildings while setting up picturesque views. The new road follows a winding route in harmony with the existing topography, and which allows the views within the site to unfold gradually and naturally. The curving forms of the new roadways and parking areas are sensitively landscaped, and they frame a central area that will be the site for a future ground-mounted solar array garden at the heart of the unifying campus landscape. Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 27 of 32 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) Revised January 24, 2023 Application for Amendment January 12, 2023 28 of 32 • 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. Figure 8: S40 Campus Phasing Plan Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 29 of 32 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) Revised January 24, 2023 Application for Amendment January 12, 2023 30 of 32 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. Beta Technologies Master Plan (MP-21-02) Revised January 24, 2023 Application for Amendment January 12, 2023 31 of 32 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.

The development program for the BETA campus includes the construction of an approximately 285,000 square foot manufacturing facility, a 25,000 square foot training facility, a 75 student Daycare Center, and a 37,800 square foot commercial building with retail and office space. The main access and egress to the project site is provided via a proposed new site driveway on US 2 (Williston Road) east of Valley Road, with secondary access for trucks provided via Aviation Avenue. This Traffic Impact Study includes the following elements: • A description of the existing roadway network in the vicinity of the site; • A summary of crash data within the study area; • Identification of any major permitted developments in the project vicinity; • A description of the proposed development program; • A trip generation estimate for the proposed development program; • An evaluation of the allowed trips per the land area of the proposed site; • An evaluation of traffic operations during weekday morning and evening peak hours for 2022 and 2027 at the intersections of US 2 (Williston Road) with the proposed site driveway, US 2 (Williston Road) / Industrial Avenue, US 2 (Williston Road) / US 2 (Williston Road) with Shunpike Road and Valley Road, US 2 (Williston Road) and Aviation Avenue, US 2 (Williston Road) / Kennedy Drive / Airport Drive, Kennedy Drive / Kimball Avenue, US 2 (Williston Road) / VT 116 (Hinesburg Road) / Patchen Road; and, • Conclusions and recommendations to support the project. EXISTING CONDITIONS The proposed project site is located on the southeast edge of the Burlington International Airport grounds in South Burlington, Vermont. Primary access to the adjacent roadway network will be provided via a proposed site driveway onto US 2 (Williston Road) directly south of the site and east of Valley Road, with truck access provided via Aviation Avenue. The location of the site in relation to the local roadway network is shown in Figure 1 on the following page. Ref: 58568.00 January 17, 2022 Page 2 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx Figure 1: Site Location Map Roadway and Intersection Characteristics US 2 (Williston Road) is classified as a major arterial in the project vicinity and carries approximately 13,900 vehicles per day between Airport Drive / Kennedy Drive and the South Burlington/Williston town line.1 The segment of US 2 in the vicinity of the proposed site driveway has a posted speed limit of 40 mph with a two-lane cross-section and striped bicycle lanes in each direction. West of the proposed site driveway near Millham Court, US 2 transitions to a 35-mph speed limit and a three-lane cross-section with one through vehicle travel lane in each direction, a shared two-way left turn lane, and bikes lanes in each direction. US 2 also serves as a primary transit corridor through this area, with existing Green Mountain Transit Red line stops at Shunpike Road / Valley Road and Aviation Avenue in proximity to the project site. 1 2018 AADT based on 2017 count at Site Location ID D036 and accessed via the VTrans Transportation Data Management System. Ref: 58568.00 January 17, 2022 Page 3 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx US 2 at Shunpike Road and Valley Road (unsignalized): US 2 intersects with Shunpike Road and Valley Road at an unsignalized, two-way stop-controlled intersection located approximately 340 feet west of the proposed site driveway. At this intersection, US 2 has a single through lane in each direction and the two minor legs of the intersection meet US 2 at a slight offset. Shunpike Road connects to Kimball Avenue and provides access to a residential area while Valley Road provides access to a small commercial area. The northbound and southbound approaches to the intersection are single lane and stop-controlled. Bicycle lanes are designated in both the eastbound and westbound directions along US 2. Shunpike Road has a sidewalk on the west side of the road which connects to the sidewalk on the south side of US 2 west of Shunpike Road. US 2 at Aviation Avenue (unsignalized): US 2 intersects with Aviation Avenue at an unsignalized intersection less than ½ of a mile west of the proposed driveway location. At this intersection, US 2 has a posted speed limit of 35 mph and has a single travel lane in each direction and a two-way center left-turn lane (which provides a left turn lane for eastbound US 2 vehicles turning into Aviation Avenue). The Aviation Avenue approach is stop-controlled with approximately 200-foot dedicated right and left turn lanes and a single northbound departure lane separated by a 200 foot long raised median. The posted speed limit on Aviation Avenue is 25 mph. A crosswalk is present across Aviation Avenue approximately 40 feet north of the stop bar. No crosswalks are present across US 2. Sidewalks are present along the west side of Aviation Avenue and the north side of US 2. A section of sidewalk is present along the south side of US 2 in front of the Ace Hardware. The eastbound and westbound bike lanes on US 2 continue through this intersection. Trucks traveling to and from the BETA facility will be directed to use Aviation Avenue and Eagle Drive to access the site. Figure 2 below shows that vehicle turning paths for a WB-67 design vehicle (i.e. articulated tractor- trailer with 53’ trailer) can be accommodated within the existing intersection geometry. Figure 2. Turning Paths for WB-67 Design Vehicle Ref: 58568.00 January 17, 2022 Page 4 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx US 2 at Industrial Avenue and Williston Road (signalized): US 2 intersects with Industrial Avenue at a signalized intersection 0.5 miles east of the proposed site driveway. Improvements to the intersection (currently under construction) include realignment to straighten the Williston Road through movements with an exclusive left turn lane for vehicles traveling east on Williston Road turning left onto Industrial Avenue. The southbound approach will be consistent with the previous configuration, providing dedicated lanes for those turning left or right onto Williston Road. The westbound traffic will continue to be served by a single approach lane. The posted speed limit on Williston Road is 40 mph and 30 mph on Industrial Avenue. No sidewalks or crosswalks are provided at the intersection. Consistent with the previous configuration, bike lanes are provided on both sides of Williston Road with bike crossing markings across the Industrial Avenue leg of the intersection to indicate the presence of the westbound cyclists. US 2 at Gregory Drive and Williston Road (unsignalized): US 2 intersects Gregory Drive at an unsignalized intersection less than two-tenths of a mile east of the proposed driveway location. At this intersection, US 2 has a posted speed limit of 40 mph and has a single travel lane in each direction and a dedicated left-turn lane on the eastbound and westbound approaches on US 2 (providing a left turn lane for westbound US 2 vehicles turning into Gregory Drive, and eastbound US 2 vehicles turning into Palmer Court). The Gregory Drive approach is stop-controlled with a single approach lane. No sidewalks or crosswalks are present. The eastbound and westbound bike lanes on US 2 continue through the intersection with markings indicating their presence. US 2 at Kennedy Drive and Airport Drive (signalized): US 2 intersects with Kennedy Drive and Airport Drive at a signalized intersection to the west of the proposed development site. The US 2 legs of the intersection to the east and west have three approach lanes with a dedicated left turn lane, through lane, and through/right lane. There are two departure lanes on each leg that converge to a single lane shortly downstream of the intersection. The south leg of the intersection, Kennedy Drive, is a median-divided facility with three approach lanes (left turn, thru, and right turn lanes). The north leg of the intersection, Airport Drive, provides access to Burlington International Airport with three approach lanes (left and right turn lanes and a through lane). The current traffic signal phasing runs with a protected leading left turn phase followed by concurrent phasing for through and right movements with permitted lefts on all approaches. The north, south, and west legs of the intersection have crosswalks and pedestrian pushbuttons to provide access to the sidewalks that flank both sides of US 2, the west side of Airport Drive, and the east side of Kennedy Drive. Kennedy Drive has a shared use path on the west side of the corridor. Kennedy Drive and Kimball Avenue (signalized): Kennedy Drive intersects Kimball Avenue and Bayberry Lane just south of the US 2 / Williston Road intersection. Kimball Avenue parallels Williston Road starting at the intersection with Kennedy Drive in South Burlington and connecting to Marshall Avenue and points east in Williston. The intersection with Kennedy Drive is signalized. Two through lanes and dedicated left turn lanes on the Kennedy Drive approaches facilitate north-south traffic. The Kimball Avenue approach has a single through-right lane and a dedicated left turn lane. The Bayberry Lane approach is a single lane. Kennedy Drive and Kimball Avenue have posted speed limits of 40 mph. Pedestrian crossings with push buttons and signal heads are provided across all four legs of the intersection. US 2 at VT 116 and Patchen Road (signalized): Hinesburg Road (VT 116) and Patchen Road intersects Williston Road (US 2) in South Burlington approximately nine-tenths of a mile west of its intersection with Kennedy Drive. The connection at this location provides access to the airport and Winooski to the north via Patchen Road and connection to Kennedy Drive and points south of I-89 in South Burlington and beyond via VT 116 to the south. Two approach Ref: 58568.00 January 17, 2022 Page 5 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx lanes facilitate traffic on all four legs of the intersection. In the north and south directions, these lanes include shared through and right lanes with dedicated left turn lanes. Eastbound the lanes are configured as through and shared through and right lanes, with left turns prohibited. Westbound the lanes are configured as through and shared through and left lanes. Both Williston Road and Hinesburg Road have a posted speed limit of 35 mph while Patchen Road has a posted speed limit of 25 mph. There are crosswalks with pedestrian push buttons and signal heads across all four legs of the intersection. Crash Data A review of VTrans’ most recent High Crash Location (HCL) Report (2015-2019) revealed that the nearest high crash locations to the study area include the segment of US 2 Williston Road just west of the Kennedy Drive / Airport Drive intersection and Industrial Avenue just east of the US 2 Williston Road intersection.2 The VTrans Public Crash Data Query Tool3 was reviewed to further investigate reported crashes occurring over the most recent 5-year period in the vicinity of the project. Table 1 summarizes the crashes occurring along roadway segments within the project area and at the study area intersections. The most prominent collision types on US 2 both east and west of the proposed site driveway are rear end crashes, likely resulting from turning movements into and out of the numerous curb cuts along this section of Williston Road. At the Kennedy Drive / Airport Drive intersection, there were 35 crashes in the five-year review period with the most common collision types being same-direction sideswipes and rear-end crashes. 2 VTrans, High Crash Location Report 2012-2016. 3 VTrans, Crash Data Query Tool, http://apps.vtrans.vermont.gov/CrashPublicQueryTool/ Ref: 58568.00 January 17, 2022 Page 6 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx Table 1. Crash Data for Study Area Segments and Intersections PROPOSED DEVELOPMENT PROGRAM The proposed development program for the BETA campus includes the construction of an approximately 285,000 square foot manufacturing facility, a 25,000 square foot training facility, a 75 student daycare center, and a 37,800 square foot commercial building with retail and office space. Access and egress to the project site will be provided primarily via a new site driveway to the south of the site, connecting with US 2 (Williston Road) east of Valley Road. The preliminary site plan below (Figure 3) shows the proposed site plan in addition to the internal circulation and access from US 2 via the new site driveway. The US 2/Site Driveway will be signalized with a dedicated left turn lane in the eastbound direction and dedicated left and right turn lanes exiting the site. This site driveway will provide the primary access and egress to the site. Secondary access and egress to US 2 will be provided via Eagle Drive and Aviation Avenue. This indirect connection to the broader roadway network will accommodate truck deliveries to and from the site. For the purposes of this analysis, anticipated truck trips were assigned to the Aviation Avenue access whereas the new site driveway is anticipated to provide access for all other trips to and from the site.

Transportation Demand Management strategies are planned for the anticipated workforce to encourage commuters and visitors to utilize alternative modes of transportation to and from the site. As such, the plans for on-site circulation are intended to facilitate these trips. Pedestrian walks are planned for the building side of each parking bay. Landscaped islands with planted topographic landforms divide the parking bays and discourage short cuts. Collector walks will act to funnel pedestrians laterally Ref: 58568.00 January 17, 2022 Page 8 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx across the site to one of three building entries. A large main walk is intended to connect all the collector walks and direct visitors and staff to the central main entrance. Secondary entry walks will lead to either the northwestern employee entrance or the southeastern employee entrance. Both entrances will have indoor bike parking and will be graded to be fully accessible. In addition, there will be both a sidewalk and a multi-use recreation path leading from Williston Road to the main building entrance and further into the site to a field for viewing airplanes taking off and potentially connect to future recreation paths. A recreation path is planned that will connect the other BETA facilities and airport facilities in general to this site. Significant bike parking is planned for the building including at the main entrance with short-term spaces and additional long-term covered spaces will be available within the building. A large pedestrian plaza accommodates arrival, gathering, circulation and waiting space directly outside of the main building entrance. The additional on-site sidewalks and paths will support connectivity between the existing Green Mountain Transit (GMT) bus stops located proximate to the Valley Road/Shunpike Road intersection, the proposed GMT shelter adjacent to the new BETA site driveway, and the BETA manufacturing facility. SIGHT DISTANCE Stopping sight distance is the distance required for a vehicle, traveling at the design speed, to stop before reaching a stationary object in its path, such as a stopped vehicle. The provision of adequate stopping sight distance is critical for safe operations. The 2018 Policy on Geometric Design of Highways and Streets (the “Green Book”) states that, “[i]f the available sight distance for an entering or crossing vehicle is at least equal to the appropriate stopping sight distance for the major road, then drivers have sufficient sight distance to anticipate and avoid collisions.” 4 Along Williston Road, which has a posted speed limit of 40 mph adjacent to the proposed site drive, the minimum stopping sight distance required per the AASHTO Green Book is 305 feet. VHB measured stopping sight distances in the field along US 2 approaching the proposed site driveway from the east and west. A vehicle traveling along US 2 at the posted speed of 40 mph approaching from the east has a stopping sight distance of approximately 400’ to the proposed site driveway. A vehicle approaching from the west along US 2 has a stopping sight distance of approximately 730’. Therefore, the minimum stopping sight distances are met in both directions along US 2 at the proposed site driveway. Stopping sight distances at the site driveway intersection were also evaluated based on the vertical profile of US 2. As shown in Figure 4, stopping sight distance standards along Williston Road are met with respect to the back of the anticipated queue. When considering the vertical curvature, the required stopping sight distances vary slightly according to AASHTO depending on location due to changes in grade, as noted in Figure 4. Further, the visibility of the signal heads meets AASHTO standards as depicted in the diagram. Although standards are met despite the vertical curve, a signal ahead sign may be considered in this location. 4 A Policy on Geometric Design of Highways and Streets, 7th Edition, AASHTO, 2018 Ref: 58568.00 January 17, 2022 Page 9 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx Figure 4: Sight Distance for Vehicle Approach Site Driveway from East TRAFFIC NETWORKS The weekday AM and PM commuter peak periods were selected for analysis purposes as they represent the peak conditions for both the site-generated traffic and the adjacent street system. Existing Data A turning movement count was conducted at the existing intersection of Valley Road and Shunpike Road on May 27, 2021 for the PM peak hour of 4:30 to 5:30 PM and on May 28, 2021 for the AM peak hour of 7:30 to 8:30 AM. The turning movement counts indicated that the existing four-way intersection serves 1,264 vehicles in the AM peak hour and 1,542 in the PM peak hour. VHB collected turning movement count data on Wednesday, February 3, 2021 for the intersection of US 2 at Aviation Avenue during the weekday AM peak period 7:00 to 9:00 AM and the weekday PM peak period 4:00 to 6:00 PM. The Ref: 58568.00 January 17, 2022 Page 10 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx counts indicated that the AM peak hour occurred from 7:45 to 8:45 AM when 1,144 vehicles entered the intersection and the PM peak hour occurred from 4:00 to 5:00 PM when 1,298 vehicles entered the intersection. Intersection turning movement count data was gathered from the VTrans Transportation Data Management System for the US 2 / Airport Drive / Kennedy Drive intersection. VTrans data, collected on July 2 and 3, 2018, indicated that the weekday AM peak hour occurred from 7:45 to 8:45 AM when 2,124 vehicles entered the intersection and from 4:00 to 5:00 PM when 2,364 vehicles entered the intersection. VHB collected turning movement count data on Wednesday, January 12, 2022 and Thursday, January 13, 2022 for the intersection of US 2 at Gregory Drive during the weekday AM peak period from 7:00 to 9:00 AM and the weekday PM peak period from 4:00 to 6:00 PM. The counts indicated that the AM peak hour occurred from 7:15 to 8:15 AM when 1,314 vehicles entered the intersection and the PM peak hour occurred from 4:14 to 5:15 PM when 1,472 vehicles entered the intersection. Intersection turning movement count data was gathered from the VTrans Transportation Data Management System for the US 2 Williston Road / Industrial Avenue intersection. VTrans data, collected on June 15 and 16, 2017 indicated that the weekday AM peak hour occurred from 7:30 AM to 8:30 AM when 1,532 vehicles entered the intersection and from 4:30 to 5:30 PM when 1,843 vehicles entered the intersection. To account for recent volume fluctuations due to the COVID-19 pandemic, the 2021 and 2022 traffic volumes collected at the US 2 / Valley Road / Shunpike Road, US 2 / Aviation Avenue, and US 2 / Gregory Drive intersections were added to the network and adjusted and balanced based on the 2018 traffic volume data from the US 2 / Airport Drive / Kennedy Drive intersection. This adjustment resulted in a 24% and 4% increase in traffic volumes at Shunpike Road / Valley Road, a 31% and 21% increase in traffic volumes at Aviation Avenue, and a 33% and 16% increase in traffic volumes at Gregory Drive to represent a pre-COVID condition during the weekday AM and PM peak hours, respectively. The US 2 / Hinesburg Road and Kennedy Drive / Kimball Avenue intersections were similarly added to the network and balanced to the US 2 / Kennedy Drive intersection, resulting in no adjustment to the intersection volumes with the exception of a 3% increase to Kennedy Drive / Kimball Avenue in the PM peak hour. Copies of the traffic volume count data are provided in the Appendix. Adjustments to Existing Data Since it is impractical to design for the highest volume encountered during the year, VTrans Traffic Impact Study guidelines recommend a compromise between capacity and cost. Design Hourly Volume (DHV) criteria allow roads to be designed for the 30th highest hourly volume of the year. Traffic count data at a VTrans short-term traffic count station on US 2 east of Gregory Drive was used to calculate a DHV adjustment factor of 1.00 for the study intersections5. Detailed calculations for the DHV adjustments are provided in the Appendix. 5 Count Station D036, located on US 2 just east of Gregory Drive, had an AADT of 13,921 vehicles per day in 2017. Using the AADT and the 2020 VTrans Redbook DHV Chart, the estimated DHV for the corridor was 1506 vehicles per hour.

Background traffic growth is a function of expected land development in the region. To predict a rate at which traffic can be expected to grow during the forecast period, historical traffic growth was examined. The regression analysis chart in the 2020 VTrans Redbook suggests a background adjustment rate of 1.03 to project traffic volumes from 2022 to 2027. Traffic from Other Developments Traffic associated with area projects that have undergone permitting but may not be fully occupied was included in the No Build traffic networks. Based on discussions with South Burlington’s Planning and Zoning Department staff, traffic generated by the following projects was included in the No Build traffic network: • O’Brien Farm: The O’Brien Farm project is a multi-phase mixed-use development located between Kimball Avenue, Old Farm Road, and Kennedy Drive in South Burlington. Based on discussions with South Burlington Planning and Zoning staff, trip generation from the following development phases has been included in the background traffic network: o Hillside (Phases 1 & 2): Includes the full Hillside phase of development located along O’Brien Farm Road and Two Brothers Drive. o Eastview (Residential Only): Includes the residential component of the Eastview phase of development (135 single family homes and duplexes), which is located along both sides of Old Farm Road south of Kimball Avenue. Anticipated AM and PM peak hour trips were obtained from the Traffic Impact Studies completed by Lamoureux & Dickinson for each of these developments and distributed through the study area network. • FedEx Ground Distribution Center: The FedEx Ground Distribution Center is currently under construction and located between I-89 and Community Drive in Technology Park in South Burlington. Anticipated AM and PM peak hour trips were obtained from the September 2019 Traffic Impact Study completed by VHB and distributed through the study area network. • Booska Movers Building: The Booska Movers Building is a proposed 25,560 SF commercial building with an anticipated 10 office employees and 25 field employees which is currently under construction at 410 Meadowland Drive. Anticipated AM and PM peak hour trips were estimated using rates in the 10th Edition of the ITE Trip Generation Manual6 for Land Use Code (UC) 150 Warehousing for 35 employees. The site- generated trips were then distributed through the study area network. 6 Trip Generation Manual, 10th Edition, Institute of Transportation Engineers, Washington D.C., 2017.

ITE Land Use Code 140 (Manufacturing), 710 (General Office), 22 (General Aviation) and 180 (Specialty Trade Contractor) for the training facility, 565 (Day Care Center), and 820 (Shopping Center) were applied to estimate the trips per unit (employee, students, or gross floor area). The applicant anticipates that at full occupancy, the campus will house approximately 225 manufacturing employees and 250 office employees during the first and second shifts. In addition, an onsite training facility is anticipated to have 15 employees in hangar space for BETA and general use maintenance as well as 25,000 square feet supporting training activities. A commercial building with approximately 18,900 square feet of retail and 18,900 square feet of office space is proposed along the Williston Road frontage of the campus. In addition, an employer-based daycare center supporting 75 students from BETA employees’ families is anticipated on the campus. As such, estimates of internal capture for those trips associated with the daycare were 7 Trip Generation Manual, 11th Edition, Institute of Transportation Engineers, Washington D.C., 2021.

Calculations supporting the proposed trip generation estimates for the project are provided in the Appendix. Table 2: Trip Generation Summary The new site-generated trips were distributed onto the adjacent street network based on existing traffic patterns. The anticipated distribution of the site-generated trips at the proposed site driveway reflects the average observed traffic distribution at the US 2/Aviation Avenue intersection, where approximately 75% of trips travelled to or from the west and 25% were traveling to or from the east. To evaluate the impacts associated with new truck trips accessing the site via Aviation Avenue, estimates of site- generated truck trips were developed based on the time-of-day distributions for each of the proposed land uses as noted in the ITE Trip Generation Manual 11th Edition. The truck percentages for entering / exiting trips were evaluated for each of the uses and are summarized in the appendix. Based on the splits, it was estimated that the BETA facility would generate approximately 23 entering and 3 exiting truck trips during the AM peak hour and 8 entering and 15 exiting trips during the PM peak hour. The 26 AM peak hour and 24 PM peak hour truck trips were distributed to the surrounding transportation network via Aviation Avenue. The distribution of the new site generated trips is shown in Figure 8 below.

Levels of service (LOS) were calculated based on the criteria published in the Highway Capacity Manual 6th Edition.8 Level of service is the term that defines the conditions that may occur on a given roadway or at an intersection when accommodating various traffic volume loads. Levels of service range from A to F with LOS A representing generally free flowing operating conditions and LOS F representing generally congested conditions as shown in Table 3. Table 3: LOS and Delay Thresholds The South Burlington Land Development Regulations identify minimum standards for overall level of service at signalized intersections at a LOS D during peak hours and level of service D or better for major street through movements at the site driveway. Additionally, the VTrans Level of Service Policy9 states that the Agency of Transportation’s policy is to design facilities to maintain an overall LOS C or better at signalized intersections through the design period. For two-way stop-controlled intersections, VTrans’ policy is to maintain LOS D or better for side street approaches through the design year. Unsignalized Intersection Capacity Analysis Table 4 summarizes the results of the capacity analysis for the unsignalized US 2 / Valley Road / Shunpike Road, US 2 / Aviation Avenue, and US 2 / Gregory Drive intersections during the 2022 and 2027 weekday AM and PM peak hours in the No Build and Build conditions. 8 Highway Capacity Manual, Sixth Edition: A Guide for Multimodal Mobility Analysis, Transportation Research Board, 2016. 9 Vermont Agency of Transportation Highway Design “Level of Service” Policy, VTrans, 2007 Signalized Intersection Unsignalized Intersection LOS A ≤ 10 0 - 10 B > 10 - 20 > 10 - 15 C > 20 - 35 > 15 - 25 D > 35 - 55 > 25 - 35 E > 55 - 80 > 35 - 50 F > 80 > 50 Delay (sec) Ref: 58568.00 January 17, 2022 Page 19 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx Table 4: Unsignalized Capacity Summary In the 2027 No Build scenario at the US 2 / Valley Road / Shunpike Road intersection, the stop-controlled minor legs operate at LOS E/F conditions.

It is important to note that the volumes on this side street approach is relatively low, with approximately 52 combined trips during the AM peak hour and approximately 36 combined trips during the PM peak hour. These relatively low volumes, and the excess capacity on the approach, are reflected in low volume to capacity ratios of less than or equal to 0.22 across all scenarios. Further, the signalization of the site driveway will likely provide gaps in the traffic flow along Williston Road, allowing traffic turning on to and off of Shunpike Road more opportunities to make their exiting movements. At the US 2 / Aviation Avenue intersection, the Aviation Avenue approach is projected to operate at LOS E/F in the 2027 No Build scenario and LOS F in the 2027 Build scenario. It is important to note that Aviation Avenue is a relatively low volume approach with 12 exiting trips during the morning peak and 52 exiting trips during the evening peak. Furthermore, the Build scenarios are indicative of excess capacity on this approach as the maximum volume to capacity ratio is only 0.16. At the US 2 / Gregory Drive intersection, the side street approaches are anticipated to operate at LOS F in the AM peak hour and LOS E/F in the PM peak hour for the 2027 Build condition. These approaches operate with excess capacity as they serve relatively low volumes, with Palmer Court reaching a maximum volume to capacity ratio of 0.26 and Gregory Drive reaching a maximum volume to capacity ratio of 0.66. The proximity to the new signalized site driveway intersection will likely provide gaps in the traffic stream along Williston Road that do not exist today, allowing opportunities for the movements onto and off of each of these side streets that is not reflected in the capacity analyses presented above. Signalized Intersection Capacity Analysis In addition to the unsignalized intersections in the study area, the signalized study intersections of US 2 / Kennedy Drive / Airport Drive, US 2 / Industrial Avenue, US 2 / Hinesburg Road / Patchen Road, and Kennedy Drive / Kimball Avenue were analyzed during the 2022 and 2027 peak hours. In addition, the intersection of US 2 and the new site driveway was analyzed.

The addition of site-generated trips to this intersection is expected to increase the overall intersection delay by less than three seconds during both peak periods. The Build scenario results assumed an optimization of signal timing to accommodate the additional traffic introduced from the proposed development. The US 2 / Industrial Avenue intersection is anticipated to operate at overall LOS C in the 2027 AM and PM Peak Hour Build conditions, with site-generated trips expected to increase overall delay by less than 5 seconds. The new intersection configuration that is being implemented as part of the current construction at this intersection is represented in the capacity analysis. The US 2 / VT 116 Hinesburg Road / Patchen Road intersection is expected to operate at overall LOS B in the 2027 AM Peak Hour Build condition and overall LOS C in the 2027 PM Peak Hour Build condition. The increase in delay based on site-generated trips is expected to be less than 3 seconds for any of the scenarios. The Kennedy Drive / Kimball Avenue intersection is expected to operate at LOS C overall, consistent across all scenarios. The site-generated trips are anticipated to increase the overall delay at the intersection by less than 3 seconds. Table 6. Signalized Intersection Capacity Analysis for Site Driveway The signalized site driveway is expected to operate at LOS C in the AM peak hour and LOS B in the PM peak hour for both the 2022 and 2027 Build conditions. The signalization of the intersection will provide significantly improved delay conditions for the site driveway compared to the unsignalized condition, where the site driveway was anticipated to operate at LOS F.

The warrant analysis is outlined below. In addition to the proposed development program for the Campus Plan, the site driveway capacity analysis was conducted for an additional 5% increase to the trip generation. With an additional 5% increase in trips to and from the site, there would be less than a 5 second increase to the overall delay at the site driveway intersection in either the AM or PM peak period, with the intersection continuing to operate at an LOS C. Intersection Signal Warrants The proposed US 2 / Site Driveway intersection was evaluated using the traffic signal warrant methodology outlined in the Manual on Uniform Traffic Control Devices (MUTCD)10 to determine if a signal was warranted at this location. For the new site driveway approach, the hourly distribution of vehicle trips according to ITE for Land Use Code 140 (Manufacturing) and Land Use Code 710 (General Office) were used to estimate the 24-hour distribution of site- generated trips. The manufacturing hourly distribution was used to distribute the manufacturing trip generation and the office distribution was used to distribute the other trip generation for the site and background data redistributed from Valley Road. For the Williston Road approaches, the daily distribution was estimated based on the hourly distribution of traffic collected at VTrans traffic count station D036 on Williston Road east of the proposed site driveway. Based on guidance from the MUTCD, the warrant analysis was conducted with the assumptions that the left- and right-turn lanes on the minor street approach be considered a single lane approach and that some portion of the southbound right movements from minor street be subtracted from the minor-street traffic estimates11. For the purposes of the warrant analysis, two-thirds of the expected right-turning traffic volume was removed from the data based on anticipated right-turn on red or eastbound left-turn overlap phase movements. Warrant 1 – Eight-Hour Vehicular Volumes Warrant 1 – Condition A, the minimum vehicular volume, is used for intersections where a large volume of intersecting traffic is present. Warrant 1 – Condition A requires that the total hourly volume for the major street and the higher hourly volume of the minor street satisfies the thresholds of Condition A for any eight-hours of the day. For a condition with single approach lanes on the major street and single approach on the minor street, the hourly volume thresholds are 500 and 150, respectively. Based on the 2022 Build volumes, Warrant 1 – Condition A was met for four hours, not satisfying the warrant. Warrant 1 – Condition B, the interruption of continuous traffic, is used for intersections where the major street traffic volumes are so high that the minor street suffers lengthy delays. Warrant 1 – Condition B requires that the total hourly volume for the major street and the higher hourly volume of the minor street satisfy the thresholds of Condition B for any eight hours. For a condition with single approach lanes on the major street and a single lane approach on the 10 Manual on Uniform Traffic Control Devices, FHWA, 2012 11 Manual on Uniform Traffic Control Devices Section 4C.01 Guidance 08 and 09 Ref: 58568.00 January 17, 2022 Page 24 \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\TIS - Proposed BETA Facility - Campus Plan - 2022-01-17.docx minor street, the volume thresholds are 750 and 75 respectively. Based on the 2022 Build traffic volumes, Warrant 1 – Condition B was met for ten hours, satisfying the criteria for the warrant. Warrant 2 – Four-Hour Vehicular Volumes Warrant 2 requires that the total hourly volume for the major street and the higher hourly volume of the minor street satisfy the thresholds of Warrant 2 for any four-hours. Based on the 2022 Build traffic volumes, Warrant 2 met ten hours, satisfying the warrant. Warrant 3 – Peak-Hour Warrant 3 requires that the total hourly volume for the major street and the higher hourly volume of the minor street satisfy the thresholds of Warrant 3 during the peak hour. Based on the 2022 build condition, Warrant 3 was met for six unique hours. It is important to note that this signal warrant applies to cases where a land use like office complexes or manufacturing facilities are likely to attract and discharge traffic over a short period, as is anticipated with this development. Signal Warrant Summary As summarized in Table 7 below, the projected traffic volumes at the US 2 / Site Driveway intersection meet the eight- hour, four-hour, or peak-hour traffic signal warrants typically required by VTrans for installation of a traffic signal. Based on these results, we conclude that for the proposed Campus Plan build out of the site, a traffic signal is warranted. It is recommended that geometric changes to the intersection including new turn lanes are implemented and any conduit required for a signal is installed at earlier stages of development in preparation for the warranted signal condition with the Campus Plan development program. Routine traffic monitoring in earlier stages of development should indicate when the traffic volumes satisfy the traffic signal warrants.

Section 10.02.G of the LDRs allows for a “trip budget” of 45 peak hour trips for every 40,000 square feet of parcel land area within Zone 3. The full planned unit development lot size of 37.6 acres (1,637,856 square feet). Applying the trip rate specified in the LDRs to the total parcel area yields a maximum trip budget of 1,843 PM peak hour trips for the development, which is summarized in Table 8 below. The anticipated peak hour trip generation for the proposed site is 513 trips, which is below the calculated trip generation budget for this site. Table 8: Calculation of Traffic Overlay District Traffic Budget CONCLUSIONS This Traffic Impact Study evaluated the traffic impacts of a proposed aircraft manufacturing facility and campus plan build out for a site located in the southeast corner of the Burlington International Airport grounds in South Burlington, Vermont. The proposed development program includes the construction of an approximately 285,000 square foot manufacturing facility, a 25,000 square foot training facility, a 75 student daycare center, and a 37,800 square foot commercial building with retail and office space. The main access and egress to the project site is provided via a proposed new site driveway on US 2 (Williston Road) east of Valley Road, with secondary access for trucks provided via Aviation Avenue. The proposed development program is anticipated to generate 499 new trips during the weekday AM peak hour and 513 new trips during the weekday PM peak hour. With these trips distributed onto the adjacent roadway network, the unsignalized intersections are anticipated to experience delays on stop-controlled minor street movements with levels of service ranging from LOS C through LOS F, and with volume to capacity ratios indicative of excess capacity. In addition, the unsignalized intersections in close proximity to the new signalized site driveway are anticipated to 12 City of South Burlington Land Development Regulations.

The signalized intersections in the study area are anticipated to operate at a LOS D or better in the 2027 Build scenarios. With the site-generated trips distributed to the network, increases in overall delay at the signalized intersections within the study area are expected to be less than 5 seconds. The proposed signalized intersection at the site driveway is anticipated to operate at LOS C in the AM peak hour and LOS B in the PM peak hour. Based on the 8- hour, 4-hour, and peak hour signal warrants, the volumes for the proposed development program satisfy the criteria for signalizing the intersection. The estimated site trip generation is below the maximum trip budget allotted by South Burlington’s Land Development Regulations for a project of this size accessing a facility within the City’s designated Traffic Overlay District Zone 3. The following off-site traffic mitigation measure was identified in this study: • US 2 / Site Driveway Intersection: Construct a signalized intersection with a single westbound lane, an eastbound dedicated left-turn lane and through lane, and two southbound approach lanes on the site driveway. Beyond the off-site traffic mitigation measure outlined above, the applicant is considering the following Transportation Demand Management (TDM) measures to promote alternative modes of commuting and reduce the number of single-occupant vehicle trips generated by the proposed development: • Provision of on-site covered bike parking and locker rooms with showers to encourage bike-commuting. • The parking area will incorporate priority parking spaces for carpool-only use to encourage employees to share rides to and from the facility. • Provision of company-sponsored Green Mountain Transit (GMT) bus passes to employees to encourage commuting via public transit. • Potential provision of a new GMT bus shelter along the property’s Williston Road frontage to supplement the existing sign-only bus stop adjacent to the US 2/Valley Road intersection. • Considering becoming a member of the Chittenden Area Transportation Management Association (CATMA) to help ensure that employees have continued access to TDM resources and opportunities. The above TDM measures are currently under consideration by the Applicant and have been provided for informational purposes. For the traffic analysis included in this Study, no TDM-related reductions were factored into the trip generation estimate at this time. In conclusion, based on the findings of this Traffic Impact Study, and in consideration of the identified traffic mitigation measures, the proposed project is not anticipated to generate unreasonable congestion or unsafe conditions on the adjacent roadway network. \\vhb\gbl\proj\SBurlington\58568.00 Industrial Facility\docs\memos\Appendix\Industrial Development Appendices Cover Sheet.docx Technical Appendix Traffic ➢ Safety Assessment Data o Crash Review Data ➢ Sight Distance Assessment o Intersection Sight Distance Vertical Curve ➢ Traffic Data & Trip Generation o US 2 Williston Road AADT and DHV o Growth Factors and DHV Estimation from VTrans Redbook o AM and PM Peak Hour Intersection Worksheets o Site Specific Development Trip Network o 2022 & 2027 No Build Trip Network o Trip Generation o Trip Generation Trip Network o 2022 & 2027 Build Network o South Burlington Land Development Regulations ➢ Intersection Capacity Analyses o 2022 AM No Build & Build Reports o 2022 PM No Build & Build Reports o 2027 AM No Build & Build Reports o 2027 PM No Build & Build Reports o 2027 Build Queuing Reports ➢ Signal Warrant Analysis o Summary o Warrant 1 Analysis o Warrant 2 Analysis o Warrant 3 Analysis
