The project consists of authorizing the continued use of a contractor’s yard to place fill materials, 24 Berard Drive. COMMENTS The Board reviewed this application on September 14, 2023. The Board continued the hearing for the purpose of allowing the applicant to address Board feedback, particularly on the southern access to the site. The applicant provided a vehicle turning movement plan to demonstrate their proposal. A) SITE PLAN REVIEW STANDARDS 14.07 Specific Review Standards C. Access and Circulation. All proposed development shall comply with site access and circulation standards of Section 15.A.14. The site has two access points on Berard Drive, one at the north off the cul-de-sac and a second at the southern end of the public street frontage. The Board on September 19 expressed concern that the southern entrance created unsafe conditions on Berard Drive due to the extremely limited sight distance of approximately 40-ft. As noted in the September 19 report, the speed limit on Berard Drive is 25 mph and on-street parking is permitted on either side. The southern access point was developed for the adjoining property but merged with the subject property in 2004 when a subdivision took place to convey land from the southern property to the subject property. The applicant is proposing an equipment storage area near the southern end of the frontage on Berard Drive that would be accessed via the southern entrance. The Board directed the applicant to provide a design that modified the southern entrance to create a safe configuration. The plan submitted by the applicant entitled “Southern Access Drive Plan,” dated 9/27/2023, depicts the entrance movement of a 29-foot non-articulated three axle vehicle, a representation of which is shown on the plan. The truck is depicted as not crossing the center line of Berard Drive when it enters the site 2 at 6 mph, or a crawl speed. The applicant has proposed to widen the entrance radius to 30-ft on both north and south sides of the driveway, though it is unclear why widening on the north is proposed since the entrance is proposed to be one-way in only, and Berard Drive is a dead end street. Given the existence of a northern entrance which does not appear to have as many potential issues, Staff recommend the Board discuss the following aspects of the proposal with the applicant. 1. The design vehicle. As Staff alluded to on September 19, construction equipment is typically moved on articulated “low-boy” trailers much larger than the vehicle shown on the submitted plan. 2. The design speed. Staff considers the design should default to success rather than provide a solution that only works in limited circumstances. What is a typical speed for an entering vehicle? 3. The northern curb radius. Based on the discussion on 9/19, it seems a one-way in entrance should not require anything but a very modest radius on the northern side. If the objective is sight distance, a tree clearing zone should instead be proposed. RECOMMENDATION Staff recommends that the Board work with the applicant to address the issues identified herein. 1.This plan is in no way a boundary survey. Property lines shown are based on tax map information from the City of South Burlington and a plan entitled "Property To Be Conveyed By Alan & Maureen Pidgeon Boundary Line Adjustment for Alan & Maureen Pidgeon & K&S Properties, LLC To Vermont Transco LLC, Berard Drive, South Burlington, Vermont" by Vermont Surveying and Engineering, dated 12-28-10 and recorded in Map Slide 557, Page 2 of the City of South Burlington Land Records. 2.The horizontal coordinate system is based on NAD83 Vermont State Plane 4400 (US Survey Feet). Elevations are based on the NAVD88 datum (US Survey Feet). 3.Existing utilities shown are not warranted to be exact or complete. Contractor shall contact DIG SAFE and other non-member utilities prior to beginning any excavation. 4.Existing conditions shown are based on 2014 LiDAR data from the Vermont Center for Geographic Information (VCGI), and a topographic survey by Krebs & Lansing Consulting Engineers in May 2023.
