In advance of the Development Review Board meeting on June 4, 2024, we are providing a response to staff comments. Two plansheets have been revised and resubmitted in response to these comments. These plansheets have cloud revision bubbles around the proposed changes. The appropriate file naming convention (noting the revision date in the file name) has been made and they have been uploaded to the ShareFile Site Plan Application submission folder. The revised plansheets are referenced in the the response to comments below: 1. There is no safe pedestrian access to the building from Davinci Drive either existing or proposed, though there is a sidewalk along Davinci Drive. Given the proposed use of the building for students, and the City’s prioritization of personal mobility (ie biking and walking), Staff recommends the Board discuss with the applicant how to improve access to the site for users that are not arriving in cars or buses. Response: A walkway and crosswalk with signage have been added to the site plan (06_SP-01 - SITE PLANS_REV20240531) to provide the requested pedestrian access from the recently constructed Da Vinci Drive sidewalk. 2. Staff recommends the Board ask the applicant to demonstrate that the parking is the minimum necessary and discuss whether they will allow this exemption for parking. Response: The net increase in parking of 26 spaces is the minimum necessary for the school’s proposed operations. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com 3. Staff recommends the Board ask the applicant to demonstrate that the proposed pavement is minimized near the entrance to Davinci Drive. Too wide open a pavement area with multiple (four in this case) non-perpendicular locations for cars to come from can lead to safety issues. The driveway at the west end is narrow, so it does not appear this area is needed for large vehicle circulation. Response: The pavement width in this area is necessary for the operations of the Beta loading docks. This is an existing condition as that entrance was just paved last year as part of the Beta assembly plant project. This widened pavement is also necessary for the school buses to make their turn movement from the bus loading area onto Da Vinci Drive. 4. Staff recommends the Board ask the applicant to explain at what point the existing overhead utilities will be located underground, and consider requiring the utilities to be located underground at the upstream most pole that is impacted by the work. Response: The existing power service to the building is currently underground from the adjacent transformer and this transformer is powered via underground conduits to the pole near Da Vinci Drive. With the installation of a new transformer this same underground configuration is being proposed as shown on the Utility Site Plan. 5. Staff recommends the Board ask the applicant to verbally answer the questions of the Director of Public Works and include conditions for any necessary modifications. ●The applicant will need to work with the wastewater superintendent to confirm that the project has a sufficient wastewater allocation for the change in use. Response: A coordination meeting was held with the water & sewer department after the submission of our Water & Sewer Engineers report to the City, which resulted in the issuance of an Ability To Serve letter by the water district and verbal concurrence for wastewater. The Ability To Serve letteris included in our application. ●The wastewater pump station will remain privately owned. Response: Correct ●Does the property have an existing oil / water / grease / grit separator? Will the change in use require that one be installed? Response: An existing oil/water separator exists for the current floor drains and will be rehabilitated or replaced as part of the proposed project. The proposed kitchenette area will be for warming food only, and no food preparation will occur onsite. Therefore a grease trap is not required. ●Are any water (or other) easements proposed to be transferred to the City? Response: No 6. The applicant is proposing an on-grade striped pathway from the parking area to the building. Staff recommends the Board consider requiring the pathway to be raised by a curb and consider requiring a sidewalk connection and crosswalk to Davinci Drive, as alluded to above. Response: See response to #1 above. A raised walkway was not proposed as stormwater runoff from traverses across the pavement to the existing closed drainage systems. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com 7. The building is 34,445 sf and is proposed to be used by 12 employees and 100 students. One short term space is required for each 20 students of planned capacity, or five spaces. It does not appear the applicant has proposed any bicycle parking. Staff recommends the Board require the applicant to add short term bicycle parking to the plan proximate to a student entrance. Response: The project is proposing 8 bike spaces as shown on drawing SP-02. These are covered spaces with a bike rack. The project is also planning for 2 interior bike lockers as well. 8. No parking lot landscaping is proposed. Staff recommends the Board require the applicant to revise their plans to provide landscaping to screen the proposed and reconfigured parking from the future public street. Response: The landscaping plan, drawing LL-02 (14_LL-02 - LIGHTING & LANDSCAPING PLAN_REV 20240531) has been revised to include additional plantings around the existing parking lot that will be expanded. The locations for proposed plantings are limited due to the slopes between DaVinci Drive and the parking area. 9. Staff recommends the Board require the applicant to demonstrate compliance with this criterion by providing a figure showing the parking area and the fraction landscaped. (2) In all parking areas containing twenty-eight (28) or more contiguous parking spaces and/or in parking lots with more than a single circulation lane, at least ten percent (10%) of the interior of the parking lot shall be landscaped islands planted with trees, shrubs and other plants. Such requirement shall not apply to structured parking or below ground parking. Response: Although the parking area has more than 28 spaces, it is a single drive isle with no opportunities for internal landscape areas. In response to these comments, additional landscaping is proposed around the parking lot as described in the response to #8 above. 10. No curbing is proposed. Staff considers curbing will be required to protect adjacent landscaping except where the adjacent area is specifically designed as a stormwater collection or treatment area. Response: Curbing is proposed along the frontage of the building as well as on the Da Vinci Road side of the parking lot expansion area. Curbing is intentionally not proposed between the proposed work area and the GA Hangar pavement areas because it would restrict the current stormwater runoff from this area into the existing closed drainage system. The proposed work includes a stone line channel to direct the runoff to the proposed bioretention basin for treatment prior to entering the existing drainage system. 11. While Staff considers the proposed plantings to not be sufficient replacement for the removed trees, as described above, the applicant must also provide parking lot landscaping, including shade trees. Staff considers the combined resulting planting likely to be adequate to replace the removed trees, and recommends the Board confirm once the proposed parking lot planting plan is complete. Response: Additional plantings have been added, please refer to the response to #8 above. 355 Main Street | Suite 500 | Winooski, VT 05404 | w. eivtech.com 12. Staff recommends the Board provide Staff an opportunity to provide an update at the time of the hearing. (related to any stormwater comments, none received to date) Response: No response required at this time, we had a pre-application meeting with the stormwater department and can answer any additional comments they may have. 13. Staff recommends the Board require the applicant to demonstrate submission of an application for Determination of No Hazard, and condition the approval on receipt of an issued determination. (Development within the Airport Approach Cones) Response: This is not applicable as it is only required for new or expanded buildings. This is an existing buildings and submission of a FAA 7460 airspace analysis review is not required. 14. Staff notes there is one “hotspot” of 15 footcandles near the eastern entrance of the building and recommends the Board discuss whether to direct the applicant to reconfigure the proposed lighting to reduce this hotspot to on the order of 8 – 10 footcandles. Response: This is the result of three closely spaced man doors with lights over each door, the center man door light has been removed to reduce the light intensity in this isolated area to less than 10 footcandles. Please see the revised drawing LL-02 (14_LL-02 - LIGHTING & LANDSCAPING PLAN_REV 20240531). 15. Screening is proposed for the proposed generator but not for the proposed utility transformer. Staff recommends the Board ask the applicant to describe the proposed height of the generator in order to determine if screening is adequate. Response: At this time the generator is expected to be roughly 8-9’ in height based on preliminary sizing. The proposed plantings will partially screen the generator. 16. Staff recommends the Board require the applicant to provide screening of sufficient height to screen the transformer from the street. Response: Additional plantings have been added between the transformer and the sidewalk as screening as shown on the revised drawing LL-02 (14_LL-02 - LIGHTING & LANDSCAPING PLAN_REV 20240531). We would propose grasses similar to what is proposed in front of the generator. These would provide a partial screening to the height of the transform (estimated to be 5-6’ in height) but would also still allow access to the transformer for maintenance & inspections.
