South Burlington DRB closes hearing on Autumn Hill Meadows final plat after questions on wetlands, buildable area and access

The South Burlington Development Review Board on April 1 closed the public hearing on final plat application SD-2504 from Autumn Hill Meadows LLC, which would subdivide an existing 13.51-acre parcel at 197 Autumn Hill Road into a 0.79-acre Lot 1 containing two existing barns and a roughly 12.72-acre Lot 2 (the remaining lands).

Staff emphasized outstanding technical details that the board asked the applicant to clarify before the board considers final approval. Those included separate buildable-area figures for the existing parcel and each proposed lot, a clearer rationale for subdividing now, modifications to the illustrative plan to show access to existing homes on Autumn Hill Road, civic-space location and size, and stormwater-area calculations in relation to wetland protections.

Why it matters: the property lies adjacent to a class-2 wetland complex and natural-resource-protection (NRP) lands. How the city treats buffers, buildable acreage and road connections will affect whether future development of the larger remainder lot is feasible and how traffic and wetlands are managed.

The applicant’s representative, Brian Currier of Larry Burke Civil Associates, told the board the illustrative plan for Lot 2 is conceptual and meant to demonstrate that the subdivision will not reduce the remaining lands’ development potential. “We are showing a layout with 36 units on the eastern side of a class 2 wetland complex and then a small fourplex on the southwest corner,” Currier said, adding the layout was “purely for illustrative purposes at this point” and that the applicant has “no intention in moving forward with this development proposal in the near future.”

Owner Christopher Jurio said the reason for subdividing now is to preserve an option for future development: “Because we would like to develop that lot. Housing is needed. It's important. It's right next to the road,” Jurio said. Currier and staff said that the 2-acre carve-out in city rules influenced the applicant’s chosen subdivision approach.

Staff asked for more precise buildable-area figures. Currier acknowledged the original submission combined the buildable area for both lots; after pulling up revised plans he reported the separated figures: about 5.18 acres of buildable area associated with the remaining lands (Lot 2) and roughly 0.5 acre for Lot 1 (the barns). Staff had originally reported a combined figure of about 6.04 acres; Currier said right-of-way acreage likely caused the discrepancy.

On density and unit mix, staff recalculated the minimum-required density at 5.18 acres as 31 units; the applicant’s illustrative plan currently shows 33 units (mostly fourplexes). Currier agreed the unit mix could be adjusted if a development application moved forward: “We could break some fours into some threes and twos,” he said. Staff had also asked the applicant to show civic space equal to 10 percent of the buildable area; the applicant removed one fourplex on the illustrative plan to provide that hatched civic space.

Wetlands, buffers and site features drew prolonged discussion. Marla (city staff) read the staff recommendation that Article 12 (the city’s wetland protection standards) governs and that the board should require modifications or protections as needed. The city’s standard 100-foot wetland buffer and the state’s typical 50-foot criterion were discussed; Currier said the wetland delineation was performed about two years ago by Gerald Environmental. On demarcation and maintenance around the barns, Currier and the owner said the lawn area between and behind the barns has historically been mowed and maintained, and the board indicated it was comfortable allowing flexibility to treat that area as an existing maintained lawn for the purposes of the Article 12 analysis, while noting limits on expansion within buffers.

The board also questioned whether the proposed subdivision would create a block longer than city standards and whether the new road alignment would be feasible given wetland crossing limitations. Currier said redundant wetland crossings are difficult to permit and that any future road connection would need to conform with wetland permitting. The applicant is showing a future road connection that would consolidate local access with Windswept (an existing road), and staff and neighbors discussed whether eliminating a short segment of Autumn Hill Road would concentrate traffic or reduce curb cuts onto Dorset Street. Board member Mark, who served when Windswept was approved, said a single consolidated connection was the development plan agreed in the prior approvals; neighbors urged the board to weigh potential traffic impacts if Lot 2 is ever developed.

Public comment included two nearby residents. Michael Todd of 123 Windswept Avenue asked why Autumn Hill Road could not remain and the town maintain two separate curb cuts onto Dorset Street to distribute traffic; board members replied the original plan anticipated consolidating access to reduce closely spaced curb cuts. Resident Heidi Goldberg of 153 Windswept Lane told the board approved prior developments under difficult conditions and said recent construction had already created neighborhood traffic and construction impacts; she asked the board to consider adverse effects if Lot 2 is developed at higher density than earlier approvals anticipated.

The board heard staff’s list of recommended conditions and clarifications (buildable-area maps and narratives, a requirement to show access to existing homes, an illustrative plan that demonstrates civic spaces and stormwater sizing, and a condition that any materially different future development for Lot 2 provide an alternative illustrative plan prior to approval). The board voiced general agreement with several staff recommendations during the hearing; however, no final approval of the plat was recorded at the meeting.

Formal action taken: the board moved, seconded and unanimously voted to close the public hearing on SD-2504; the board did not vote on final plat approval at this session.

Next steps: the applicant was directed to provide the separated buildable-area calculations, revised illustrative plans showing access to existing homes and civic-space demarcation, clarification on stormwater area calculations relative to the 5 percent threshold, and any alternative illustrative plan required if a future Lot 2 development departs from the current illustration. The board indicated staff would include conditions requiring compliance with the city’s standards and Article 12 protections if the project proceeds to final approval.

Ending note: No final plat decision was made on April 1. The public hearing was closed and the board asked staff and the applicant to return with the requested clarifications and revised plans before any approval vote.
