Please find our responses to each item below. Submission Requirement Response Street Frontage. Maintain internally-consistent building setbacks and landscaping along the street. At sketch, the applicant stated the proposed addition would be located predominantly behind the existing narrow building section connecting the parking garage second level walkway to the main terminal building relative to the public way. However it appears there are approximately 113 ft of additional building protruding beyond the existing narrow building section. In addition, it appears there may be additional building height proposed above the existing narrow building section. 1. To facilitate review of this criterion, Staff recommends the Board ask the applicant to walk through existing and proposed conditions plans and elevations with the intention of clarifying what the scope of the proposed addition will be when viewed from the public way. This information should include what will be visually different when the project is complete, including both geographic changes and exterior finish changes. The building will not protrude beyond existing building infrastructure. Please see additional view graphics from the public way (Airport Drive) enclosed with this letter. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Submission Requirement Response Transition Contrast in Scale. Minimize and mitigate abrupt contrasts in scale between existing, planned or approved development, and proposed development. 2. The addition is proposed to be three stories with a total height of 40 ft. No statement as to the height of the existing terminal building has been made. Staff recommends the Board ask the applicant to describe the height of the existing terminal and of each section of parking garage and then consider whether this criterion is met. The total building height is 51 ft 8 in. Below is a summary for the height of other nearby structures: North Garage: 58’ (at northeast corner) North Garage (stairwell): 78’ Control Tower: 91’ Existing terminal: 35’-45’ (varies) Old control tower: 45’ Pedestrian Orientation. Improve and enhance pedestrian connections and walkability within the area proposed for development. The applicant has not submitted a proposed conditions site plan, making compliance with this criterion difficult to evaluate. Based on a review of provided utility and grading plans, it appears the applicant may be disrupting an existing sidewalk with a new driveway crossing. 3. Staff recommends the Board require the applicant to provide a proposed conditions site plan to allow evaluation of this and other site related criterion. Pedestrian routes will be maintained during construction. See site plan C3.106 enclosed with this letter. This includes proposed conditions. The Development Review Board shall encourage the use of a combination of common materials and architectural characteristics (e.g., rhythm, color, texture, form or detailing), landscaping, buffers, screens and visual interruptions to create attractive transitions between buildings of different architectural styles. The applicant has not provided architectural renderings and the provided elevation drawings do not call out colors or materials. 4. To the extent appropriate for how much of the building will be visible from the public way, Staff recommends the Board require the applicant to provide architectural renderings (or more simplified elevations with materials) of the exterior of the building in the context of the surrounding buildings permit evaluation of compliance with this criterion. Please see additional view graphics from the public way (Airport Drive) enclosed with this letter. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Submission Requirement Response Pedestrian Connection. Pedestrian access must include direct (shortest linear distance) pedestrian sidewalk or path connections from local streets to the main entrances of principal buildings, civic spaces, recreation paths, shared parking areas, and existing or planned transit stops or facilities. 5. As discussed above, it is somewhat unclear what pedestrian impacts are proposed. Staff recommends revisiting this criterion when the above-recommended proposed conditions plan is provided. Pedestrian routes will be maintained during construction. See site plan C3.106 enclosed with this letter. This includes proposed conditions. Solar-Ready Zone. New buildings subject to this Section for which a complete application is submitted following the date these Regulations become effective, shall be required to meet the standards of C402.5 Solar-Ready Zone of the Commercial Building Energy Standards as prepared and revised by the Vermont Department of Public Service. 6. Staff recommends the Board require the applicant to demonstrate a solar ready zone in compliance with the CBES prior to closing the hearing. The building is oriented properly and also includes low sloped roofs.”A solar-ready zone shall be located on the roof of buildings and are oriented between 110 degrees and 270 degrees of true north or have low-slope roofs. Solar-ready zones shall comply with Sections C402.5.2 through C402.5.8.” We may fall under the exemption of a building with a permanently installed, on-site renewable energy system by including geothermal wells as part of this project. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Submission Requirement Response Electric Vehicle Charging. All parking spaces associated with new buildings or new dwelling units subject to the CBES standards shall be built to EV-Ready standards, whenever EV-Capable Space standards are required by the CBES. This requirement applies to all parking facilities associated with such buildings, regardless of the number of parking spaces provided. Substitution of Level 3 chargers for EVSE shall not reduce the number of EVSE parking spaces at a building subject to CBES by more than 50% of the number required for compliance. No new parking spaces are proposed. However, it could be asserted that at least a portion of the existing parking spaces are associated with the proposed new building. This section is intended to provide a requirement for construction of EV-ready spaces when EV-capable spaces are required by Vermont state law. 7. Staff recommends the Board direct the applicant to provide the determination on whether EV-capable spaces are required under the CBES, and if so, provide an assessment of the required number of EV-ready standards for the new building and compare this number to the number of EV charging spaces provided. The Patrick Leahy Burlington International Airport currently has six EV parking spaces in the parking garage, one EV parking space in the front of the terminal, and two airside EV parking spaces along the terminal building for aviation operations. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Submission Requirement Response This section shall apply to the receipt of a zoning permit for the construction and subsequent alteration of any building that, beginning May 11, 2023 is required by these regulations and/or the CBES, as amended from time to time, to establish a “solar-ready zone”. For any such building required to establish a solar-ready zone, there shall be installed a solar photovoltaic (“Solar PV”) system designed to maximize the use of the area of the Solar-Ready Zone employing typical Solar PV panel configurations. 8. This standard goes on to provide some reductions and an alternative compliance pathway if the applicant seeks to pursue it. Staff recommends the Board ask the applicant to review this section and determine whether they will meet the standard by providing an on-site photovoltaic system as described above or whether they will seek reduction prior to closing the hearing. Specific demonstration of compliance of the installed system with the solar-ready zone can be a condition to be addressed prior to issuance of a zoning permit. The building is oriented properly and also includes low sloped roofs. ‘A solar-ready zone shall be located on the roof of buildings and are oriented between 110 degrees and 270 degrees of true north or have low-slope roofs. Solar-ready zones shall comply with Sections C402.5.2 through C402.5.8.’ We may fall under the exemption of a building with a permanently installed, on-site renewable energy system by including geothermal wells as part of this project. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Submission Requirement Response The applicant has submitted a Passenger Trip Generation letter, prepared by Jacobs Engineering and dated October 3, 2024 and included the packet for the Board. This letter asserts that the average annual growth forecast for the airport enplanements is 0.8%, which will result in annual enplanements in 2038 matching the peak enplanement which occurred in 2009. The letter further asserts that the peak trips on Airport Drive occur outside of the PM peak hour, but does not provide supporting data. The Jacobs engineering letter does not draw a conclusion of the number of PM peak hour trips generated by the existing airport terminal or by the proposed project. The Airport’s 2022 master plan is available here https://btvmasterplan.com/public-information/. Chapter 3 discusses enplanements and includes that the 2038 enplanement forecast is 787,012, while Chapter 5 discusses peak vehicle trips though it stops short of providing a total forecasted number of trips. Staff was unable to locate data supporting Jacobs Engineering’s claim that enplanement in 2038 will match 2009 values. In attempting to provide a baseline number of trips, Staff has located the 2009 Forecast Letter Report for the airport which was approved by the FAA. This 2009 Forecast Letter provides measurement of PM peak hour trips. Staff considers the approved master plan and the 2009 Forecast Letter demonstrates the airport can and does evaluate PM peak hour trips. 9. Staff recommends the Board require the applicant to provide an assessment of existing trips and increased trips based on the planned capacity of the proposed North Concourse terminal expansion. The Patrick Leahy Burlington International Airport’s enplanements was 660,097 in 2023. By applying the 0.8% annual increase over a 10-year period, we forecast 720,566 enplanements in 2034. This number of enplanements is below the 2009 number of enplanements. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Submission Requirement Response The DRB or Administrative Officer may, at their discretion, declare multiple buildings that are part of a single parcel, application, master plan or master plan phase, to be a single entity for the purposes of calculating TDM requirements. 10. Staff supports the trips being considered on a master plan basis. However, Staff also supports TDM being applied on a phase-by-phase basis if that is the most appropriate strategy for this particular master plan. We anticipate applying Traffic Demand Management calculations and requirements on a phase-by-phase basis. Bicycle Parking and Storage The applicant upgraded the site to meet the current bicycle parking requirements as part of the south terminal expansion project approved in SP-21-018. Therefore they must now provide bicycle parking spaces to meet the requirements for the proposed addition, consisting of one short term space per 5,000 sf and one long term space per 10,000 sf. 11. The applicant has submitted a mark-up of the previously approved analysis of bicycle parking requirements. However it is unclear what the conclusions are of the markup. Staff recommends the Board require the applicant to provide, in tabular format, the following information. Please see the bicycle parking chart on the following page. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Short Term Bike Parking Requirements (existing and proposed) Long Term Bike Parking Requirements (existing and proposed) Existing Terminal Building 32 N/A* Existing FAA Building 4 N/A* QTA Rental Car Facility 4 2 Terminal Integration Project 7 4 BTV North Terminal 12 6 TOTAL 59 12 Number of Short Term Spaces Number of Long Term Spaces Garage Location #1 (south of vehicle entry lanes) 59 12 (includes 2 new for BTV North Terminal) TOTAL 59 12 Required Bike Parking: *Long term parking spots were not required for original portions of the Terminal or FAA building Provided Bike Parking: 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Submission Requirement Response Exterior Lighting Lighting requirements are summarized as follows. (1) Fixtures must be downcast and shielded (2) Illumination must be evenly distributed (3) Fixtures must be placed to minimize lighting from becoming a nuisance (4) Poles shall be rustproof metal, cast iron, fiberglass, finished wood or similar structural material, with a decorative surface or finish (5) Poles & building mounted fixtures may be no higher than 30-ft (6) Poles must be located in safe locations Specific requirements for maximum illumination levels are included in Appendix A and are limited to 3-foot candles average at ground level. The applicant has submitted photometric drawings for the tarmac side of the airport, within the airport security fence. Staff has been unable to locate drawings indicating the location of or resulting illumination from proposed illumination on the public side of the proposed building, nor has the applicant made a statement that there is no proposed change to illumination on the public side of the building. 12. Staff recommends the Board require the applicant to provide demonstration of compliance with exterior lighting criteria, including photometric drawings and lighting cut sheets, for any illumination which will be visible to the public including on the north side of the proposed addition within the security fence. We are adding an additional photometric plansheet for the three lighting fixtures along the north side of the terminal and one on the west side of the terminal, located on the north wall of the pedestrian bridge. These lighting fixtures will meet the exterior lighting requirements described within the staff comment, and they are consistent with the exterior lighting fixtures recently installed as part of the Terminal Integration Project (TIP). This photometric plan is enclosed with this letter. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com Submission Requirement Response Fences The applicant indicated at sketch that they were proposing to extend the existing wrought iron fence from the north end of the building to connect to the existing fence north of the building. However this does not appear to be shown on the applicant’s plans nor is a detail provided. The existing fence is metal with metal spikes on top, which is prohibited in the LDR. Historically the Board has considered airport security fencing exempt from regulation under 24 V.S.A. § 4413. 13. Nonetheless, Staff recommends the Board require the applicant to show the location and provide a detail for the proposed fence. Please find an enclosed plansheet title ‘Proposed Landside Grading and Utility Plan with Fence Detail’. This plansheet shows the location for using the existing wrought iron fence, and a photo provides a detail for the existing fence material.
