This project is part of the BETA Campus Master Plan MP-21-02 (“Master Plan”). We believe this submission meets the stated goals of the City’s plans and specific standards as described in the Land Development Regulations as adopted on May 12, 2022. PROJECT DESCRIPTION BETA proposes to construct a paved and curbed parking lot as part of the “Blue” phase of the Master Plan. This includes 261 parking spaces and sidewalks connecting users to the BETA assembly facility. The project is located on the south end of Burlington International Airport’s property at 154 Da Vinci Drive. CONSTRUCTION COST Estimated cost for the project is $550,000. DIMENSIONAL STANDARDS The project area used to calculate coverage is defined by the master plan site area of 40.6 acres, in which 11.52 acres falls within the I/C zoning district. See the BETA PUD lot coverage tracking table for more information.

During the A-build sub-phase, a portion of the facility and most of the parking is to be constructed. Under the Full-build sub-phase, the balance of the building and remaining parking lot will be constructed. The A-build portion of the project without the parking lot is currently approved under ZP-22-163. The applicant intends to seek separate zoning permits for the A-build sub-phase parking lot, as described within this narrative, and the Full-build sub-phase. LANDSCAPING The landscaping, as approved under SD-21-028 will be installed within and around the parking lot meeting the requirements of the Land Development regulations as summarized below: Conformance with LDR’s: • Approximately 36%, as compared to the required 10%, of the interior of the parking lot includes landscaped islands planted with trees. • Interior and perimeter plantings are protected by curbing. • An abundance of trees are provided within or near the perimeter of the parking area with at least 1 tree for every five (5) parking spaces. • Landscape budget has been met (as approved under SD-21-028). • Snow storage areas have been defined on C-010, Overall Site Plan. • Approved trees have a caliper equal to or greater than two and one-half (2 ½) inches when measured on the tree stem, six (6) inches above the root ball. TRAFFIC A traffic impact study (TIS) was reviewed and approved under MP-21-02 with a supplemental TIS reviewed and approved under SD-21-028. The proposed parking lot has no impact on the results of those previous studies. LIGHTING Site lighting, as approved under SD-21-028, will utilize pole-mounted fixtures for the parking areas. All exterior lighting will be LED fixtures with full cutoff, dark-sky 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 are DLC or Energy Star rated. Conformance with LDR’s: • Maximum fixture height is 25’ compared to the 30’ maximum allowed. • Full cut-off lights fixtures proposed. • Illumination levels at ground level will be less than 3-footcandles average. • Indirect glare produced by illumination at ground level does not exceed 0.3-footcandles maximum, and 0.1-footcandle average. October 28, 2022 South Burlington Development Review Board Page 3 of 4 Reference: BETA Technologies – Campus Parking Site Plan Application Narrative PARKING This application is requesting additional parking spaces for both the A-build and Full-build phases approved under SD-21-28. For the Full-build sub-phase, the applicant is proposing 261 additional parking spaces from the 55 approved. For the A-build sub-phase the applicant is proposing 226 additional parking spaces from the 41 currently approved. Vehicle Parking: Under section 14.06(A)(2)(a) of the land development regulations, the City requires that parking shall be located to the rear or sides of buildings. Provision 14.06(A)(2)(b)(viii) provides an exemption to this provision when the building, or a portion thereof, being served by the parking area is contained within the Security Identification Display Area (SIDA) of a publicly owned and operated airport. As this building is contained with the SIDA, the Applicant is requesting the proposed parking be approved under the exemption provision as described. Bicycle Parking: Approval for the applicants plan for bike racks, indoor bike storage, lockers and showers was issued under SD-21-28 for the BETA Assembly Facility. STORMWATER The stormwater treatment practices, and collection system approved under SD-21-28 have been designed, sized and permitted to treat and detain the stormwater runoff from the proposed parking lot and sidewalks in accordance with the City’s stormwater regulations. Erosion protection and sediment control measures will be installed as detailed in plans previously provided under SD-21-28.
