The subject parcel is an existing 0.71 acre lot, 1459 Shelburne Road. The Board held a hearing on this application on March 2, 2022 and continued the hearing to address outstanding issues. The remainder of this memo presents a summary of what Staff considers to be outstanding issues requiring discussion with the Board. Outstanding items are organized into “above the line” comments which Staff considers require a deeper discussion by the Board, and “below the line” comments with which Staff considers the Board may wish to simply confirm the applicant’s concurrence. The Board is encouraged to review the March 2 staff notes and discuss any items for which they feel additional testimony is needed. ABOVE-THE-LINE COMMENTS 13.04 Landscaping, Screening & Street Trees G(3) Landscaping Budget Requirements. The Development Review Board shall require minimum planting costs for all site plans, as shown in Table 13-4 below. In evaluating landscaping requirements, some credit may be granted for existing trees or for site improvements other than tree planting as long as the objectives of this section are not reduced. The costs below are cumulative; for example, a landscaping budget shall be required to show a planned expenditure of three percent of the first $250,000 in construction or improvement cost plus two percent of the next $250,000 in construction or improvement cost, plus one percent of the remaining cost over $500,000. The landscaping budget shall be prepared by a landscape architect or professional landscape designer. The building cost is $1,400,000, requiring a minimum landscaping value of $21,500. The applicant has calculated that they have provided $8,000 in trees and shrubs on the lot, and $1,500 in trees and shrubs on the adjacent lot. There is no provision in the LDR for off-site landscaping to count towards the required minimum landscaping value. It appears there is an error in the applicant’s landscape cost, where they are proposing three maple trees but have only accounted for the cost of two maple trees. Two maples are on the adjacent lot, but Staff considers the value should be adjusted upward by $600 to include the inadvertently omitted maple. The applicant has requested the Board allow $7,100 of cost for the front brick walkway and brick patio be allowed to count towards the required minimum landscaping value. 180 Market Street, South Burlington, Vermont 05403 | 802-846-4106 | www.southburlingtonvt.gov 1. The front brick walkway may add a limited amount of value to the site because of its limited visibility and limited anticipated use. Staff recommends the Board consider whether to allow the front brick walkway to contribute towards the minimum required landscaping value or whether other site features, such at the planned playground, may be a better use of required value. If the playground or other site features are used, full details and cost information are required. 2. For the brick patio (and brick walkway if allowed), Staff recommends the Board require the applicant to provide a detailed cost breakdown demonstrating that the requested hardscape value is only the value beyond the value of standard concrete. The applicant has proposed a $3,600 value for retention of the existing 18-inch maple. They arrived at this value by calculating the equivalent cost of six 3-inch trees. Staff supports this computation and recommends the Board allow the proposed value for retention of the existing 18-inch maple. However, Staff recommends the Board require the applicant to supplement the provided erosion and sediment prevention plans with a detail for protection of the tree, subject to review and approval by the City Arborist. Taking into consideration the above listed landscaping values, including on-site trees, shrubs, hardscape, and existing tree retention, the applicant is proposing $19,300 of the required minimum landscaping value. The applicant has requested to include $2,700 in “installation and maintenance cost.” Installation and maintenance cost are not allowed to be counted towards the minimum required landscaping value. The applicant must provide an additional $2,200 in plants or hardscape. As noted above, the applicant has proposed 2 – 3 inch caliper trees, while the minimum size is 2 ½”. 3. Staff recommends the Board require the applicant to increase the minimum tree size and recalculate the proposed landscaping cost, adding on-site plantings as necessary to achieve the required minimum landscaping budget. As a reminder, the City Arborist reviewed the plans on 2/15/2022 and offered the following comments. • Should provide Tree Protection Plan and Details for any existing trees to be retained. Leaving the decision to preserve the existing 18 inch maple on the west side of the building should not be left up to the contractor, if the tree is going to be retained the appropriate tree protection measures must be on the plans and applied. • Recommend continuous planting pits filled with loam/sandy loam soil to a depth of 2ft in parking lot bump outs to provide adequate soils for tree/plant growth • The landscape budget detailed on the plans may not meet minimum requirements. There is a clause indicating that the city requirement is $20,000 but only $7300 is listed with a stipulation that additional costs at the time of installation will meet the requirement 4. The Board on 3/2 supported the City Arborists suggestion to require the applicant to retain the 18- inch maple. Staff continues to recommend the Board require the applicant to modify their erosion prevention and sediment control plan to provide robust tree protection around the drip edge of the existing tree. 180 Market Street, South Burlington, Vermont 05403 | 802-846-4106 | www.southburlingtonvt.gov Staff continues to recommend the Board require the applicant to modifying their tree planting details to incorporate the comments of the City Arborist. Staff considers this can be addressed as a condition of approval. B(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. 5. The Board has historically applied this standard across parking lots regardless of property boundaries. This criterion is not met for the parking lot shared by this and the adjacent parcel to the south. Staff recommends the Board require the applicant to demonstrate how they will meet this criterion for the shared parking lot prior to closing the hearing. Staff anticipates the actual interior landscaping will be provided on the adjacent parcel to the south. B(7) Snow storage areas must be specified and located in an area that minimizes the potential for erosion and contaminated runoff into any adjacent or nearby surface waters. 6. The applicant has not proposed any on-site snow storage. Staff notes the applicant has indicated three areas on the adjoining site plan as “additional snow storage.” One area contains a mature tree between the parking and the indicated area. Staff recommends the Board ask the applicant to describe how snow storage will be addressed for the subject property. BELOW THE LINE COMMENTS 13.04 Landscaping, Screening & Street Trees B. Except for parking spaces accessory to a one-family or two-family dwelling, all off-street parking areas subject to review by the Development Review Board, shall be curbed and landscaped with appropriate trees, shrubs, and other plants including ground covers, as approved by the Development Review Board. Sections of recessed curb are permitted if their purpose is to allow stormwater runoff from the adjacent parking area to reach stormwater collection, treatment and management infrastructure. The Development Review Board shall consider the adequacy of the proposed landscaping to assure the establishment of a safe, convenient, and attractive parking area and the privacy and comfort of abutting properties. (1) All off-street parking areas shall be landscaped around the perimeter of the lot with trees, shrubs and other plants. Perimeter planting shall be set back from the curb sufficiently to allow for snow storage. The purpose of perimeter planting shall be to mitigate the view of the parking lot from the public way and from adjacent uses and properties, and to provide shade and canopy for the parking lot. In some situations it may be necessary both for surveillance purposes and for the perception of safety to install the size and type of plants that leave visual access between the parking lot to the public way or other pedestrian areas. In response to Staff comments, the applicant has augmented the landscaping screening of new parking areas. Staff considers this criterion met to the extent feasible and necessary. 180 Market Street, South Burlington, Vermont 05403 | 802-846-4106 | www.southburlingtonvt.gov (3) All interior and perimeter planting shall be protected by curbing unless specifically designed as a collection and treatment area for management of stormwater runoff as per 13.04(B)(5)(c) below. Interior planted islands shall have a minimum dimension of six (6) feet on any one side, and shall have a minimum square footage of sixty (60) square feet. Large islands are encouraged. Curbing is proposed except where stormwater is proposed to be addressed by sheet flow. 13.04B above indicates that only small sections of curbing should be removed for stormwater. However, the applicant has protected the planting by locating it on the far side of the stormwater swale, which Staff considers as meeting this criterion. The applicant has revised the plans to remove proposed curbing from one of the interior parking lot landscaping islands located on the adjacent site at 1475 Shelburne Road. Staff notes that protecting this planting island with curbing will be a requirement of the site plan application for the adjoining site. (4) Landscaping Requirements (a) Landscaping shall include a variety of trees, shrubs, grasses and ground covers. All planting shall be species hardy for the region and, if located in areas receiving road runoff or salt spray, shall be salt-tolerant. The provided trees are a variety of species. Staff considers this criterion met. (b) At least one (1) major deciduous shade tree shall be provided within or near the perimeter of each parking area, for every five (5) parking spaces. The trees shall be placed evenly throughout the parking lot to provide shade and reduce glare. Trees shall be placed a minimum of thirty (30) feet apart. There are 14 parking spaces proposed. The applicant is proposing two shade trees on the adjacent lot, and proposing to retain an existing 18-inch maple and install one shade tree. Staff considers these trees when taken together meet this requirement, provided the proposed site plan on the adjoining lot proceeds as envisioned, with modifications to curbing and interior parking lot landscaping noted above. (c) Trees shall have a caliper equal to or greater than two and one-half (2 ½) inches when measured on the tree stem, six (6) inches above the root ball. The applicant has proposed 2 to 3 inch caliper trees. This does not meet the standard. 7. Staff recommends the Board require the applicant to provide trees with a minimum of 2 ½ inches at the time of installation. (d) Where more than ten (10) trees are installed, a mix of species is encouraged; the species should be grouped or located in a manner that reinforces the design and layout of the parking lot and the site. Fewer than 10 trees are proposed. 14.06 General Site Plan Review Standards C. Relationship of Structures and Site to Adjoining Area. 180 Market Street, South Burlington, Vermont 05403 | 802-846-4106 | www.southburlingtonvt.gov (1) 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. (2) Proposed structures shall be related harmoniously to themselves, the terrain and to existing buildings and roads in the vicinity that have a visual relationship to the proposed structures. The applicant has provided renderings and photographs showing how the proposed building relates to the adjoining building containing the associated childcare to the south as View 3 (Exhibit F). The adjoining building is Victorian in style while the proposed building is a modern craftsman style. While this is a stand-alone site plan application, the applicant is proposing to share some site features between the adjoining sites, therefore Staff considers compliance with these criteria to be particularly relevant. The applicant provided the following narrative response to these criteria Proposed materials are similar to adjacent preschool building using horizontal clapboard siding & shakes. The aesthetics are also intended to compliment the adjacent preschool building being more residential in nature and creating a campus like feel. There are other buildings along Shelburne Rd of this vernacular, examples being the Shearer Acura dealership and the Lakewood Commons buildings, not far north of the site, and Shelburne Square building on corner of IDX & Shelburne Rd, which use more residential siding materials & forms. Larger glazed openings and standing seam roof of proposed daycare building add some modern elements & textures to a more traditional style. Other properties to the north of the site are currently single story buildings with flat roofs. The gable roof of the proposed daycare building will help in transitioning from these lower adjacent structures to the existing 2 story Victorian style daycare building. 8. On March 2, the Board briefly reviewed these criteria and did not voice any opposition. Staff recommends the Board confirm they are satisfied these criteria are met. 9. The proposed site layout is strongly integrated into the site layout for the adjacent property to the south. Staff recommends the Board include a condition of approval that this project may not obtain a zoning permit before a site plan approval for the adjacent site is obtained. 14.07 Specific Site Plan Review Standards C. Access and Circulation. All proposed development shall comply with site access and circulation standards of Section 15.A.14. Much of 15.A.14 pertains to the construction of streets, which are not applicable to this application. 10. The March 2 staff report included the comment that the proposed one way signage was not in a location which will be useful to users of the site. The applicant provided an additional one-way sign on the curve of the driveway, but retained the one-way sign at the entrance on Shelburne Road. Staff recommends that sign be relocated to be just east of the first five parking spaces, as that is the first location where people could inadvertently go the wrong way. If the applicant wishes to retain 180 Market Street, South Burlington, Vermont 05403 | 802-846-4106 | www.southburlingtonvt.gov the sign at the entrance, they may, but Staff still considers a sign east of the first five spaces to be needed. 13.05 Stormwater Management Stormwater standards apply when one-half acre or more of impervious surface exists or is proposed to exist, and where 5,000 sf of impervious is created or reconstructed. The City Stormwater Section reviewed the proposed plans on 2/22/2022 and offered a number of comments. On 3/24/2022, the City Stormwater Section confirmed with Staff that their comments had been addressed. 13.07 Exterior Lighting & 13.13 Signs The March 2 staff report noted that Fixture Type “G,” a flood light, is prohibited. The applicant clarified to Staff that the fixture was for illuminating the sign. Signs, and sign lighting, is subject to separate ordinance. Staff recommends the Board require the applicant to remove all proposed signage, including callouts on the site drawings and signage on the architectural plans, as well as sign lighting, from the plans as a condition of approval. Other lighting requirements are met. 13.11 Fences 11. The applicant has shown a fence on the plans but no fence details are provided. Staff recommends the Board require the applicant to provide a fence detail demonstrating compliance with the LDR. If the applicant can provide a general description of the fence, Staff considers provision of a detail can be a condition of approval. RECOMMENDATION Staff recommends that the Board work with the applicant to address the issues identified herein. Respectfully submitted, Marla Keene, P.E. Development Review Planner
