The remainder of this memo presents a summary of what Staff considers to be outstanding issues. The Board is encouraged to review the September 8 staff notes and discuss any items for which they feel additional testimony is needed. PROJECT DESCRPTION: Preliminary and final plat application #SD‐21‐21 of Donald and Lois Kerwin to amend a previously approved Planned Unit Development of two lots. The amendment is to subdivide Lot 2 (0.83 acres) into three lots of 0.28 acres each in order to develop a single family home on each, 1420 Hinesburg Road. OUTSTANDING ISSUES TO BE ADDRESSED: 1. TREES: The Board directed the applicant to add two trees between each building and the eastern lot line in order to support consistency with the existing neighborhood. The applicant has provided a landscaping plan prepared by Michael Lawrence & Associates Landscape Architects and dated October 2021 which provides five maple trees between the buildings and the eastern lot line. The specified size is 3‐6 feet, which is not consistent with the City’s minimum 2 ½” caliper. Staff recommends the Board require the applicant to modify the plantings to reference caliper, and provide a minimum of 2 ½” caliper, for the trees between the buildings and the eastern lot line. The applicant has also provided a number of additional trees and shrubs around the foundation of each building. Since no supplemental narrative was provided, it is unclear whether the intention of the applicant is for the plants to be representative of what may be planted, or if the applicant is proposing some commitment to these plants. Staff recommends the Board ask the applicant to describe their intention, and then the Board determine whether to require all or some of the proposed plantings. Staff notes the specified sizes at planting for any required trees should be by caliper, with a minimum planting size of 2 ½”. Finally, the applicant has proposed a vegetated rain garden as mitigation for the proposed wetland impacts. This rain garden is discussed pertaining to wetland impacts below. Staff has requested the City Arborist review the plans. Staff anticipates they will have an update at the time of the hearing. #SD‐21‐21 2 2. WETLANDS: The project is proposing to impact all 1,742 sf of Class III wetland and all of the associated 50‐ ft buffer (area of impact not provided). On 9/8, the Board provided feedback to the applicant that they needed more information to determine compliance with LDR 12.02E. 12.02E(3) Encroachment into Class II wetland buffers, Class III wetlands and Class III wetland buffers, may be permitted by the DRB upon finding that the proposed project’s overall development, erosion control, stormwater treatment system, provisions for stream buffering, and landscaping plan achieve the following standards for wetland protection: As was noted on 9/8, the Board is not obligated to permit wetland encroachment. In the case of this PUD, the proposed Lot 3 is the location of the home in the previously‐approved but not yet constructed PUD approval (#SD‐19‐35). The wetland was not identified as part of that application. Staff considers that since the DRB did not permit the wetland impacts as part of #SD‐19‐35, wetland impacts associated with that permit are prohibited. Therefore if the DRB does not approve this application, the applicant would have to reconfigure the previously‐approved lot to avoid wetland or wetland buffer impacts in order to obtain a zoning permit. The Board should consider the following standards in determining whether to permit the proposed wetland encroachment. (a) The encroachment(s) will not adversely affect the ability of the property to carry or store flood waters adequately; The applicant provided the following response to the Board’s request for additional information on 10/5/2021. Since the wetland is essentially an overgrown lawn, as stated in the original response the elimination of the wetland or its buffer will not adversely impact the flood water storage capacity. However, in support of improving on the existing storage potential in the area, a rain garden has been incorporated into a portion of the wetland area between the homes. The existing foundation drain is proposed to be day‐lighted into the rain garden and with the improved subsoil, will better enable the water to infiltrate back into the ground. (b) The encroachment(s) will not adversely affect the ability of the proposed stormwater treatment system to reduce sedimentation according to state standards; The applicant provided the following response to the Board’s request for additional information on 10/5/2021. The Arrowwood Environmental wetland report indicated that the wetland does not exhibit any of the function of values set forth by the State including the ability to prevent erosion and trap sediment. However, the addition of the rain garden will provide some additional treatment and infiltration of runoff on lots 2 and 3. With the reduced size of the driveways and a fully vegetated site, it is not anticipated that there will be a lot of sediment that is expected to be generated by these lots. (c) The impact of the encroachment(s) on the specific wetland functions and values identified in the field delineation and wetland report is minimized and/or offset by appropriate landscaping, stormwater treatment, stream buffering, and/or other mitigation measures. The wetland memorandum prepared by Arrowwood Environmental and dated 7/1/2021 indicates that the wetland was determined to be Class III on 6/28/2021, which determination is valid for five years. The Class III determination indicates that its functions and values do not merit protection under the Vermont Wetland Rules at this time. This is because the State does not regulate Class III wetlands. #SD‐21‐21 3 However, the City has chosen to apply the wetland protection standards to Class III wetlands and buffers. The ten wetland functions and values are as follows. 1. Water Storage. 2. Water Quality Protection. 3. Fish Habitat. 4. Wildlife Habitat. 5. Sensitive Species. 6. Exemplary Communities. 7. Education and Research. 8. Recreation. 9. Open Space. 10. Erosion Control. The applicant provided the following response to the Board’s request for additional information on 9/21/2021. The Arrowwood Environmental report specifically identified that the wetland does not provide any of the State’s ten (10) function and values review standards. Since there are no identified functions to be mitigated though design approaches, the design of the proposed rain garden will provide a dedicated environment for small storm infiltration and will add aesthetic value to the site that otherwise is not presently found. The grading of lots 2 and 3 has been designed to provide positive drainage towards the rain garden to be able to provide some supplemental stormwater treatment on the site. A supplemental landscaping plan has also been developed for those areas not associated with the proposed rain garden. Staff considers the provided rain garden to be appropriate mitigation for the impacted wetland given that it captures flow which previously fed the wetland as well as surface runoff from the proposed roofs. Staff recommends the Board include a condition requiring the rain garden be maintained in perpetuity. Staff further recommends the Board require the applicant to update the civil engineering drawings to reflect the grading and utilities shown on the landscaping plan. 3. DRIVEWAY DRAINAGE: Because the previous proposal routed an existing drainage ditch through 15‐inch culverts with significantly less than 12‐inches of cover, the applicant indicated to Staff via phone conversation on 10/5/2021 they would modify the plans to route the existing drainage ditch over the driveways. However, the plans provided on October 5, 2021 do not reflect this discussed modification. Staff recommends the Board ask the applicant to provide an update. 4. BUILDING DESIGN: The Board directed the applicant to increase the glazing on the south facing façade of the sample elevations. The applicant has done so. They have provided a computation indicating that at least 35% of the area of the south façade will be glazed. As Staff stated at the hearing on 9/8, this is not the standard. The standard is that 35% of the glazing should be on the south facing façade. Staff recommends the Board review the provided elevations and floor plans and determine whether to include a condition that 35% of the south façade be glazed, as proposed by the applicant, or whether to require the standard of 35% of glazing to be south facing, consistent with the LDR. As much as Staff #SD‐21‐21 4 supports natural light as a good design principal, Staff considers the provided elevations result in a potentially untenable amount of glazing relative to interior home design. RECOMMENDATION Staff recommends that the Board work with the applicant to address the issues identified herein.
