CONTEXT The Board held a hearing on this application on August 2, 2022. The Board reviewed the application with the applicant, provided feedback, and continued the hearing for the purpose of allowing the applicant to make necessary modifications to the project for the project to be compliant with the City’s Land Development Regulations and to continue review of the portions of the staff report that there was insufficient time to address on August 2. The applicant provided revised materials on September 6. Review of these revised materials is incorporated herein; criterion which Staff considers to have been addressed have been removed from this report. PERMIT HISTORY The official map includes two planned roadways in the Tilley Drive area, one extending north from Tilley Drive on Lot 2 to the O’Brien property to the north and one extending east from the existing cul-de-sac on Tilley Drive to Community Drive. The DRB recently reviewed projects that addressed each of these connections, the north connection with the O’Brien Eastview approval (preliminary plat #SD-20-40, final plat application #SD-22-10) and the east connection with the OnLogic approval (final plat #SD-21-26 & site plan #SP-21-046). Both of those projects accommodated the planned roadway connections as required in the LDR. The O’Brien Eastview application is discussed further in this report. COMMENTS (1) MASTER PLAN REQUIREMENTS 15.B.02(A) Required Approval. Master plan review and approval by the DRB is required prior to preliminary subdivision review under Article 15.A, or site plan review under Article 14, as applicable, for: (4) The DRB may also require the submission of a Master Plan for any tract or parcel of land where there exists clear potential for future growth and development beyond that presented in an application, as necessary to establish physical and functional connections between areas of proposed and potential future development. At sketch, the applicant indicated they have no intention to further develop the site beyond that presented in this application. The Board determined master plan is not required if the applicant were to in some way restrict the remaining lands from development. 1. On August 2, the Board discussed whether additional encumbrance is necessary beyond the recreation paths and easements proposed for the undeveloped portion of the lot, were inclined that it was not, but asked to see a plan to aid in their determination. Staff recommends the Board review Sheet C-1.4 and determine whether additional encumbrance is necessary. If so, Staff recommends the Board require the applicant to propose a mechanism for restricting the remaining lands from future growth at least for the 10-year period that would be represented by a master plan. (2) ZONING DISTRICT & DIMENSIONAL REQUIREMENTS Staff recommends the Board include as a condition of approval that the applicant update the proposed dimensions (coverages, setbacks, height, etc) prior to issuance of a zoning permit. (3) SITE PLAN REVIEW STANDARDS 14.06 General Review Standards A. Relationship of Proposed Structures to the Site. (1) The site shall be planned to accomplish a desirable transition from structure to site, from structure to structure, and to provide for adequate planting, safe pedestrian movement, and adequate parking areas. On August 2, the Board asked the applicant to provide a pavement striping and signage plan. A plan has been provided and included in this packet. Staff notes providing a stop bar at the downstream end of the one-way drop off loop is not recommended and the signage does not clearly indicate one-way, though there are unlabeled signs on the plan; Staff recommends the Board require the applicant to update the pavement marking and signage plan, subject to review and approval of the Director of Public Works, as a condition of approval. The DRB shall consider the following: (d) Pedestrian Orientation. Improve and enhance pedestrian connections and walkability within the area proposed for development. This criterion is related to criterion 14.07G: Access to Abutting Properties. The project is located within the Mountain View business park, which includes an existing recreation path along the north side of Tilley Drive connecting VT 116 to Community Drive. The Board is concurrently reviewing the O’Brien Eastview development project which directly abuts the subject property. At sketch, the Board discussed with the applicant the planned connections from the O’Brien Eastview property. Since that time, the O’Brien Eastview development has evolved somewhat and is now proposing a realigned recreation path that ends at the northern boundary of the subject property. On August 2, the applicant indicated a willingness to accommodate connections from the Eastview property. The applicant has revised the plans to include a right-of-way which connects to the proposed O’Brien Eastview Barn Road, and to construct a recreation path which connects between the existing Tilley Drive recreation path and the planned recreation path on the O’Brien Eastview Plans adjacent to Potash Road. The Director of Public Works reviewed the proposed plans with Staff on September 13, 2022 and indicated that the applicant should provide separate irrevocable offers for the recreation path, for Barn Road extension, and for the pocket park (details of the pocket park are discussed under 14.06C below). He also asked the Board require the applicant to construct the recreation path of standard asphalt pavement rather than permeable asphalt pavement, since no successful permeable asphalt has been yet produced by Vermont asphalt plants. If the applicant wishes to maintain the recreation path, they may include a clause in the irrevocable offer indicating the City will not accept it unless the applicant fails to maintain it to City standards. Staff considers these comments may be addressed as conditions of approval. On August 2, the Bike/Ped Committee Liaison suggested the rec path connect directly to the development instead of to Tilley Drive. Staff considers it critical that the rec path connect directly to Tilley Drive because of the importance of regional non-vehicular circulation, in addition to the presence of a number of other employers on Tilley Drive. 2. However, Staff recommends the Board consider whether they will direct the applicant to require a short spur from the rec path to the proposed building. Otherwise, Staff considers this criterion met. (2) Parking: (a) Parking shall be located to the rear or sides of buildings. Any side of a building facing a public street shall be considered a front side of a building for the purposes of this subsection. (b) The Development Review Board may approve parking between a public street and one or more buildings if the Board finds that one or more of the following criteria are met. The Board shall approve only the minimum necessary to overcome the conditions below. (i) The parking area is necessary to meet minimum requirements of the Americans with Disabilities Act; (ii) The parking area will serve a single or two-family home; (iii) The lot has unique site conditions, such as a utility easement or unstable soils, that allow for parking, but not a building, to be located adjacent to the public street 3. The Board determined on 8/2 that the parking to the front relative to Old Farm Road is allowable under (iii) below but required the applicant to add additional screening. The applicant indicated in their cover letter that they have done so, but Staff has not been able to find any differences with a side by side comparison of the landscaping plans. Staff recommends the Board ask the applicant to clarify. C. Site Amenity Requirement (3) The required area shall be: (a) For Non-Residential development, a minimum of 6% of non-residential building gross floor area. The proposed 84,006 s.f. building requires a minimum of 5,040 s.f. of Site Amenity. The applicant has modified their proposal to include a pocket park on the north east corner of the property, located in line with the proposed recreation path. Staff considers this an interesting proposal. The proposed pocket park meets the size and amenity requirements of LDR 11B. However, pocket parks are listed in 11B as typically fronting on one or two streets. There is no street in the proposed location at this time, though the street on the official map will be adjacent to the amenity when constructed. Additionally, Staff finds the idea of moving away from a car-centric design and locating the amenity on a recreation path to be interesting. It would allow employees of the facility to use the site with some privacy, and serve as a destination for those taking a walk from this and adjacent buildings 4. Staff recommends the Board determine whether to allow the applicant to use the pocket park amenity type. It should be noted that alternative amenity options are available to the applicant due to the relatively open nature of the underlying zoning district. 14.07 Specific Review Standards In all Zoning Districts and the City Center Form Based Codes District, the following standards shall apply: A. Environmental Protection Standards. All proposed development shall be subject to the applicable requirements of Article 12, Environmental Protection Standards. The property contains a Class III wetland greater than 5,000 sf and a Class III wetland less than 5,000 sf. The smaller wetland is not regulated by the City. The larger wetland has a 50-ft buffer. Development in a Class III wetland and associated 50-ft buffer is generally prohibited and is required to be left in an undisturbed, naturally vegetated condition. The following activities are permissible. (a) Restricted Infrastructure encroachment (b) Temporary impacts (c) Underground Utilities On August 2, the Board indicated that they considered the proposed impacts of the driveway on the regulated wetland to be acceptable. 5. It has come to Staff’s attention that the applicant has proposed to plant a number of trees in the regulated Class III wetland. LDR 12.06D(2) states that “Development in a Class III wetland (meeting 5,000 square foot threshold), and associated buffer within all zoning districts, is generally prohibited and shall be left in an undisturbed, naturally vegetated condition.” Staff recommends the Board require the applicant to remove the proposed trees from the undisturbed portion of the wetland and wetland buffer. B. Site Design Features. All proposed development shall comply with standards for the placement of buildings, parking and loading areas, landscaping and screening, open space, stormwater, lighting, and other applicable standards related to site design pursuant to these Land Development Regulations. These standards are contained in Article 13 and are discussed below. 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. The applicable sections of 15.A.14 follow. 15.A.14 (D) Functional Capacity and Transit Oriented Development. The nearest signalized intersection or those intersections specified by the DRB shall have an overall level of service “D” or better, at the peak street hour, including the anticipated impact of the fully developed proposed PUD or subdivision. In addition, the level of service of each through movement on the major roadway shall have a level of service of “D” or better at full buildout. The applicant provided a Traffic Impact Assessment (TIA) dated May 27, 2022. They estimate a PM peak hour trip generation of 110 trips and a total of 769 trips per day. However, they conclude these values using a reduction based on the provision of Transportation Demand Management (TDM) measures. The City’s impact fee ordinance provides a methodology for impact fee credit for TDM measures, but there is not a methodology for reduction in trips for the purpose of road network analysis. They also estimate trips based on site-specific data and not on ITE approved values. On August 2, the Board invoked technical review of the TIA. BFJ’s review is included in the packet for the Board. In summary, BFJ makes the following recommendations. Initial trip generation estimates (129 PM peak hour trips) are accurate. Internal capture should not be applied. TDM trip reduction is too high. Staff recommends the Board require the applicant to incorporate BFJ’s recommendations. Since these modifications will result in a relatively modest adjustment to the number of predicted PM peak hour trips, Staff considers this can be addressed as a condition of approval. G. Access to Abutting Properties. The reservation of land may be required on any lot for provision of access to abutting properties whenever such access is deemed necessary to reduce curb cuts onto an arterial or collector street, to provide additional access for emergency or other purposes, or to improve general access and circulation in the area. On August 2, the Board directed the applicant to provide for connection of the property to the north- south roadway on the official map. The applicant has done so, but not in the way Staff was expecting. Instead of providing for direct connection to the official map roadway, the applicant has provided for connection to the future ROW for Barn Road, which will be extended to meet the roadway on the official map. The Board on August 2 determined that reserving funds for construction of the connection between Barn Road and the official map roadway is not the responsibility of the applicant, meaning it will fall on City taxpayers to fund this connection. 6. Given that Barn Road extension is likely to be built at a later time than construction of the official map roadway, Staff recommends the Board discuss whether to require the applicant to provide for a direct connection to the future official map roadway. The applicant’s plans call out the driveway connection as a right of way. DPW director indicated no right of way offer should be provided for the proposed driveway connection and it should be indicated instead on the plans as a reserved area (or similar language), not a right of way. Staff considers this may be addressed as a condition of approval. H. Utility Services. Electric, telephone and other wire-served utility lines and service connections shall be underground insofar as feasible and subject to state public utilities regulations. Any utility installations remaining above ground shall be located so as to have a harmonious relation to neighboring properties and to the site. Standards of Section 15.A.18, Infrastructure, Utilities, and Services, shall also be met. Wire-served utilities are shown to be underground from the emergency generator to the building. However it is not indicated how non-emergency power will be served. Staff recommends the Board require the applicant to modify the plans to show non-emergency power from the source to the building, and that this connection be underground, as a condition of approval. Note: Time did not permit the remainder of this staff report to be reviewed on August 2. Staff has therefore included all relevant regulations after this point, and invites both the Board and applicant to raise any concerns they have with Staff’s interpretation, but has updated the Staff comments to reflect the revised materials submitted on 9/6/2022. (4) SUPPLEMENTAL REGULATIONS In addition to the issues identified herein, Staff noted a number of miscellaneous items on the provided plans which are not identified. 1. There are several small elements on sheet C-1.7 indicated as a grey box with the letter “B” in it. What are these elements? They may require screening if they are located above grade. 2. What is the purpose of the line around the five parking spaces near the northwest corner of the building on Sheet C-1.7? 3. The property owner is incorrect on Sheet C-1.7 7. These comments have not been addressed. Staff recommends the Board require the applicant to modify the plans to provide clarity on these items before closing the hearing. 13.02 Off Street Parking and Loading F. Access management Requirements. It is the intent of the City to minimize traffic and pedestrian conflicts caused by vehicular driveways on public roadways by reducing the number of required driveways and by minimizing the number of vehicles utilizing such driveways off public roadways. All applicants must make an effort to reduce these impacts. All commercial lots (retail, restaurant, office, service uses, excluding residential, agricultural and industrial uses) located adjacent to other commercial lots must provide a driveway connection to any adjacent commercial lot. If the adjacent property owner does not want to provide for that connection, the applicant must provide an easement to do so in the future when circumstances may change. This driveway connection or easement should be located where vehicular and pedestrian circulation is most feasible. The applicant is sharing a driveway with the property to the west. There is a future city street located between the subject property and the commercial lot to the east. As discussed above, Staff recommends the Board make a determination on the layout of the connection to the future city street. Also as noted above, the applicant has connected to the recreation path to the north, and to provided a feasible design and easement for the connection to Barn Road. G. Design requirements for Parking Spaces, Parking Aisles, Lighting and Landscaping (1) Design requirements for off-street parking and loading are provided in Table 13-2 and Figure 13-1, Section 13.04, Landscaping, Screening, and Street Trees, and Section 13.07, Exterior Lighting. All paved parking spaces shall be striped or otherwise physically delimited. Dimensional requirements are met. Parking lot landscaping and lighting are further discussed below. (2) The location of parking areas and loading docks shall prevent conflicts with entering and existing traffic onto a public street and prevent conflicts between vehicles and pedestrians. The distance between access points and parking areas shall be adequate to minimize blockage and prevent back-ups onto the public street. Staff considers this criterion met. (3) Provision shall be made for access by police, fire and emergency vehicles. The Fire Chief reviewed the plans on 7/27/2022 and indicated there were no comments related to the Board’s authority. (4) Pedestrian safety. Insofar as practicable, pedestrian and bicycle circulation shall be separated from motor vehicle circulation. Safe and convenient pedestrian circulation, including appropriate sidewalks, shall be provided on the site and its approaches. The pedestrian circulation on site shall be designed to minimize adverse effects of vehicular traffic on sidewalks and recreation paths. Staff considers this criterion to be met. (5) Bicycle parking or storage facility. See Section 13.03 (6) Stormwater management strategies that facilitate infiltration including but not limited to recessed planting islands, bioretention facilities, and pervious parking spaces are encouraged in the design of any off-street parking or loading area. Stormwater management is discussed under 13.05 below. 13.03 Bicycle Parking and Storage. The applicant has provided two bicycle racks, providing parking for four bicycles. Required Bike Parking Required Short Term (1 per 5k sf retail, restaurant, and all other uses, minimum 4) 17 Long Term (50% of short term) 9 Changing Facility and Unisex Showers 1 Clothes Lockers 3 The applicant has provided 14 inverted-U type bicycle racks near the main entrance, providing parking for 28 bicycles. Short term requirements are met. The applicant has provided twelve long term bike parking spaces and has shown where the changing facilities, clothes lockers, and showers will be located. Staff recommends the Board require demonstration of the applicant having met changing facility, shower, and locker requirements prior to issuance of a certificate of occupancy. 13.04 Landscaping, Screening & Street Trees The City Arborist reviewed the plans on 7/24/2022 and indicated the plan includes too many maples as maples are an overplanted species, but otherwise had no concerns. This comment has been woven into Staff review of landscaping criteria below. 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. Staff considers this criterion met. (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. 8. The applicant has provided testimony that this criterion is met by providing 13,812 sf of landscape islands within 84,488 sf of parking area but has not shown the areas they included. Staff recommends the Board require the applicant to provide a general diagram showing the areas used in the provided computation to verify the computation was done correctly. Staff notes such a diagram could be a simple line hand-drawn on a plan and does not need to be a formal plan. (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 provided. Staff considers this criterion met. (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. 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. 9. 270 parking spaces are provided, requiring 54 shade trees. Including trees provided on the far side of the drive aisle within the drop off area, but otherwise excluding trees which area not directly adjacent to parking spaces, Staff considers this criterion to be just met. There are eight trees on the far side of the drive aisle. The applicant has indicated they do not wish to provide shade trees on the western or northern sides of the parking lot due to neighbor requests to not block views of the mountains. The applicant has provided a few trees to the north but only low growing shrubs to the west. Staff recommends the Board discuss whether compliance with this criterion is adequate. (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. This criterion is met. (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. 10. The applicant previously provided an item-by-item breakdown of landscaping costs, which has been omitted from the revised submission, therefore Staff cannot efficiently evaluate whether as noted above and based on recommendations of the City arborist, the applicant has reduced the reliance on maples on the plan. Staff recommends the Board require the applicant to provide an updated item by item breakdown of landscaping costs to evaluate compliance with this and landscape budget requirements. (e) Within the City Center FBC District, landscaping required within this section shall not count towards meeting minimum landscape budget requirements as detailed in Section 13.04(G). This criterion is not applicable. (1) 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. Snow storage is provided. Staff considers this criterion met. C. Screening or buffering. The Development Review Board will require landscaping, fencing, land shaping and/or screening along property boundaries (lot lines) whenever it determines that a) two adjacent sites are dissimilar and should be screened or buffered from each other, or b) a property’s appearance should be improved, which property is covered excessively with pavement or structures or is otherwise insufficiently landscaped, or c) a commercial, industrial, and multi-family use abuts a residential district or institutional use, or (d) a parking or loading area is adjacent to or visible from a public street. The Board touched upon this criterion on 8/2 and the applicant has made some modifications. Staff considers this criterion to now be addressed through screening. D. Front Yards of Non-Residential and Multi-Family Uses. In the case of non-residential and multi- family uses, the required front yard and/or the frontage along designated arterial and collector streets (see Article 3, Section 3.06 for this list) shall be suitably landscaped and maintained in good appearance. Landscape elements that reduce stormwater runoff and promote stormwater infiltration are encouraged. The Development Review Board shall require the applicant to meet the provisions of sections 13.04(F) and (G). 11. On 8/2, the applicant testified that their intention is to maintain the front yard as meadow. The Board thought this was an interesting proposal and asked for a rendering showing the applicants proposal. The applicant has provided an untitled rendering showing the appearance of the building from the street. Staff recommends the Board review this rendering and the landscaping plans and determine if they consider this criterion to be met. 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 required minimum landscaping budget is $514,480.17 for an estimated project cost of $50,698,017. 12. The applicant has requested credit for $399,575 in plants but has not provided a breakdown of the types of plants as noted above pertaining to a mix of species. Staff recommends the Board require the applicant to provide a detailed cost breakdown. The applicant has also requested credit for soil amendments, mulch, weed barrier, and landscaping plant warranty. Staff recommends the Board only allow credit for installed plant materials (to include labor and plants, not soil amendments or similar), and only allow credit for perennials and grasses if the objectives of the landscaping standards are otherwise met. Staff notes the relatively open requirements of the industrial/open space zoning district allow ample space for robust plantings. Staff notes that due to the proposed use, the building cost is unusually high compared to a standard building of this size. Staff considers the Board may choose to invite the applicant to sharpen their pencil on building costs to exclude mechanical equipment to reduce the required landscaping budget, as well as consider allowing credit for hardscape materials in addition to perennials and grasses. One potential solution would to be to include a commissioned public art element in the pocket park with a certain minimum cost, whose final design could be a condition of approval. 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 project will be subject to State stormwater management standards. The City Stormwater Director reviewed the project on 7/25/2022 and offers the following comments. The Stormwater Section has reviewed the “UVM Health Network Outpatient Surgery Center” site plan prepared by Krebs & Lansing Consulting Engineers, dated 6/17/22. We would like to offer the following comments: 1. This project is located in the Potash Brook watershed. This watershed is listed as stormwater impaired by the State of Vermont Department of Environmental Conservation (DEC). 2. The project proposes to create greater than 1 acre of impervious area and disturb greater than 1 acre of land. It will therefore require a stormwater permit and construction permit from the Vermont DEC Stormwater Division. The applicant should acquire these permits before starting construction. 3. Please indicate where maintenance access for the gravel wetlands will be located. Both forebays are located relatively close to the GMP easement. Confirm if the necessary type of equipment to conduct maintenance in the forebay, such as an excavator and dump truck, are provided adequate access without any conflicts with the overhead power. 4. The outlet pipe from Gravel Wetland 1 is shown with an invert at 362.50’. Being a 24” pipe, that puts the top of pipe at 364.50’. The finished grade in this location is 365.0’, meaning there is only 6” of cover at most. The plans should be revised to provide greater cover over this outlet pipe. a. Soil materials should also be specified for the berm along the eastern side of the gravel wetland to ensure there is no seepage through the berm. b. Include anti-seep collars on the outlet pipes from the gravel wetlands. 5. Silt fence is only effective for its contributing drainage area if space every 100’, or less depending on slope. The EPSC plans should be revised to show proper spacing of silt fence. As depicted, it shows spacing of over 500’ in some locations, which would likely result in the silt fence being overwhelmed during a rain event. 6. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure. 13. It does not appear these comments have been addressed. Staff continues to recommend the Board require the applicant to address these comments prior to closing the hearing. 13.07 Exterior Lighting Lighting requirements are summarized as follows. (1) Fixtures must be downcast and shielded (2) Illumination must be evenly distributed (3) Fixtures must be placed to minimize lighting from becoming a nuisance (4) Poles shall be rustproof metal, cast iron, fiberglass, finished wood or similar structural material, with a decorative surface or finish (5) Poles & building mounted fixtures may be no higher than 30-ft (6) Poles must be located in safe locations Specific requirements for maximum illumination levels are included in Appendix A and are limited to 3 foot candles average at ground level. The applicant has provided a photometric drawing indicating this criterion is met. Based on Staff comments for the 8/2 hearing, the applicant has revised the lighting plan to provide more uniform and lower peak illumination levels to prevent lighting from becoming a nuisance. Staff considers proposed lighting levels to be appropriate. The applicant has included sign illumination on their plans. Staff notes sign illumination is subject to separate ordinance and must be removed from the plans. 14. The applicant has highlighted the specifications of each light fixture provided, but the highlighting is opaque and prevents reading the specifications, therefore compliance with the physical standards cannot be evaluated. Staff recommends the Board require the applicant to provide revised legible lighting cut sheets. 13.08 Outdoor Storage and Display A. Outdoor Storage. Outdoor storage of goods, materials, vehicles for other than daily use, and equipment shall be subject to the following provisions: (1) Any outdoor storage shall be appurtenant to the primary use of the property and shall be allowed only in nonresidential districts and upon approval of the DRB in conjunction with a site plan, conditional use and/or PUD application. Staff considers this criterion met. (2) The Development Review Board may require that outdoor storage areas in connection with commercial or industrial uses be enclosed and/or screened where the storage area may comprise an attractive nuisance, where the proposed use of the storage areas present opportunities for theft, or where the Board finds that said storage areas are in view of residentially-zoned parcels. This criterion applies to equipment. The applicant has proposed an emergency generator, two chillers, an “oxygen storage area, a transformer, and an electrical vault. Staff notes under prior LDR, landscaping standards explicitly required additional screening of equipment, but that standard has been modified in the latest LDR to be more broad as excerpted in 13.04C above. Staff considers, should the Board find it appropriate, they may choose to interpret 13.04C to require screening of equipment under the provision where the Board may require screening where “a property’s appearance should be improved, which property is covered excessively with pavement or structures or is otherwise insufficiently landscaped.” The emergency generation is proposed to be 12-ft high and is proposed to be enclosed by a 8-ft high fence surrounded by evergreen trees. Previously submitted plans had a 12-ft high fence but this has been reduced, presumably to avoid the need for the fence to be considered a structure. The chillers are proposed to be 9-ft high and are proposed to have no enclosure or screening. The oxygen farm is proposed to have a max height of 15-ft and is proposed to be enclosed by an 8-ft high fence surrounded by evergreen trees on three sides. The transformer is proposed to be 6-ft high. It is located near the northeast corner of the building along with an electrical vault and neither is proposed to be screened. The applicant has also provided an image of a fuel cell (10-ft high). On previous versions of the plans, the applicant indicated a “future fuel cell area” immediately south of the proposed oxygen storage area, but it appears to have been removed. 15. Staff recommends the Board confirm with the applicant that no approval is sought for the future fuel cell. 16. Staff recommends the Board then discuss whether, for all five or six pieces of equipment, they consider screening to be adequate, taking both this criterion and the requirements of 13.04C into consideration. RECOMMENDATION Staff recommends the Board work with the applicant to address the issues identified herein.

Comments and Additional Information The above updated plans and additional materials are for addressing comments in the Staff Report prepared July 27, 2022 and from the August 2nd, 2022 DRB meeting. 1. Staff recommends the Board require the applicant to propose a mechanism for restricting the remaining lands from future growth at least for the 10-year period that would be represented by a master plan. Staff recommends any such mechanism leaves open that the lands may be altered for non-growth development such as parks or transportation infrastructure. We view this site as 100% built out. The northern area is not conducive to future development. The UVM Medical Center has no future growth plans for this site. Based on the future roadway and shared use path connections the DRB and staff are requesting, there is very little land left on the northern end of the site. See the updated Site plan. 2. In terms of internal pedestrian movement, the applicant has provided non-standard striping for both pedestrian crossings and no parking areas. Taken in conjunction with other unusual markings on the plan, Staff recommends the Board require the applicant to provide a pavement striping and signage plan to allow review of these elements of the plan. Ms. Marla Keene, Planner University of Vermont Medical Center – Outpatient Surgery Center Site Plan Application #SP-22-032 Additional Materials for DRB September 6, 2022 3 | Page We have prepared Sheet C-1.10 Pavement Marking and Signage Plan. The crosswalk markings were adjusted to show the rectangular pavement stripes perpendicular with the path of travel and the ADA access aisles are shown more in line with the standard. See the updated Civil plans. 3. The sidewalk from the road is proposed to cross behind four ADA parking spaces. Staff recommends the Board direct the applicant to route the pedestrian pathway to the front of these spaces rather than behind them. We understand this concern. The pedestrian walkway has been relocated to in front of the four ADA parking spaces. See the updated Civil plans. 4. Staff recommends the Board ask the applicant to describe how they believe this building is oriented to the street, including information on the transparency of proposed glazing. Staff considers opaque or tinted glazing, combined with the absence of a street-facing entrance, may not result in this criterion being met. The proposed main patient entry is corner facing. The south facing façade has considerable glass to address the street and allow patients and visitors to see it clearly from a distance. The building glazing will meet and exceed the requirements for U-factor and Solar Heat Gain Coefficient as defined in the Vermont State Energy Code. The glazing tint and light characteristics will be consistent on all elevations. 5. Staff recommends the Board determine whether to require the applicant to revise their plans to complete the recreation path connection from Eastview to Tilley Drive or only to require the applicant to provide an easement to the benefit of O’Brien and the City of South Burlington to complete the connection. The UVM Medical Center has worked with O’Brien Brothers regarding their Eastview Development recreation path that abuts with the northern property line and how to connect it through Lot 6 to Tilley Drive. We are proposing a recreation path located on the eastern side of Lot 6 that connects with the proposed path in the Eastview Development and to the existing path on Tilley Drive. See the updated Civil and Landscape Plans for more information. 6. Solar Gain. Staff recommends the Board require demonstration that this criterion is met. The roof of the Outpatient Surgery Center building will be constructed to be solar ready. However, the UVMMC cannot add any additional solar per State Statute as they already have existing solar installations that exceed the 500 kW of power. Ms. Marla Keene, Planner University of Vermont Medical Center – Outpatient Surgery Center Site Plan Application #SP-22-032 Additional Materials for DRB September 6, 2022 4 | Page 7. Parking. Since this would not result in a viable building, Staff recommends the Board approve the parking between the building and Old Farm Road under condition (iii) above. In doing so, Staff recommends the Board require demonstrating that through landscaping and grading that the parking is completely screened from view of Old Farm Road. We have added additional landscaping on the northwestern portion of the site so that the proposed parking will be completely screened from view of Old Farm Road. See the updated Landscape plans. 8. Staff recommends the Board require the applicant to define the perimeter of the area they are proposing as a site amenity to allow evaluation of compliance of the entire area with the requirements of LDR 11B. We are now proposing a new site amenity: a pocket park located on the northeastern side of the property. This pocket park meets the requirements identified in Article 11B. See the Site Amenity Compliance document for more information which includes a plan showing the pocket park. It is also shown on the updated Civil and Landscape plans. 13. Staff considers the applicant must modify their plans to include the design of the roadway connection between Barn Road and the future official map roadway and provide a ROW to the City. Staff recommends the Board determine whether to require the applicant to provide a surety for the cost of this connection. Staff considers this easement may substitute for the recommended conservation plan described under Master Plan above depending on the degree to which it encumbers the property. See response to #15 below. 15. Street Layout. As discussed at Sketch, Staff recommends the Board require the applicant to provide for connection of the property to the north-south roadway on the official map. Staff recommends the Board require the applicant to show how this connection is feasible. Staff then recommends the Board consider whether to require the applicant to provide a surety for this connection to be made in the future or whether to require the applicant construct a driveway to the property line at this time. We have updated the Civil and Landscape plans to show the following future roadway connections. a. A 50 foot Right-of-Way for a future road connecting the O’Brien Eastview Development over the northern portion of the site to the eastern property line. The intent is this future Right-of-Way will connect with the future north-south road that is proposed to be located on Lot 2. Ms. Marla Keene, Planner University of Vermont Medical Center – Outpatient Surgery Center Site Plan Application #SP-22-032 Additional Materials for DRB September 6, 2022 5 | Page b. A 50 foot Right-of-Way for a future road connecting the northeastern driveway and parking area to the future road as described above. 18. The applicant is proposing two “Yard Compactors.” Staff recommends the Board require the applicant to provide more information about the screening and enclosure of these items. The compactor is screened by the building to the south and west. Below is a summary of the HVAC and outdoor equipment and proposed screening. HVAC and Outside Equipment Dimensions Proposed Screening Chillers 53' L x 7'-6" W x 9' H Evergreen trees east Generator 28' L x 12' W x 12' H 8' chain link fence Oxygen Farm 24' W x 20' D x 15' H 8' chain link fence Transformer 6' L x 10' W x 6' H Evergreen trees east Electric Vault Evergreen trees east Yard Compactors 8' H x 23' L x 8'6" W 8' metal screen west, evergreen trees east Future Fuel Cell 25' L x 10' W x 10' H Not proposed at this time The updated Landscape plans show the proposed screening for these equipment pieces. Landscaping will provide screening from the neighbors to the north and east. In addition, the grade change is considerable between the neighbors and the location of the HVAC and outdoor equipment which will also help with screening. 21. The applicant has provided 14 inverted-U type bicycle racks near the main entrance, providing parking for 28 bicycles. Short term requirements are met. It is not apparent whether long term or shower requirements are met. Staff recommends the Board require the applicant to provide updated architectural drawings clearly demonstrating how these requirements are met. We have provided more information showing the interior location of the 9 long term bicycle parking, 1 changing facility and shower, and 3 locker locations. This meets the long term and shower requirements for the project. See the Interior Bike Storage plan. 22. Staff recommends the applicant address the landscaping deficiencies in the plan indicated below by adding plants other than maples. The applicant, if they choose, may redistribute the maples, and intersperse other plantings in the already planted areas, or remove some maples from the plans and substituting other species. Ms. Marla Keene, Planner University of Vermont Medical Center – Outpatient Surgery Center Site Plan Application #SP-22-032 Additional Materials for DRB September 6, 2022 6 | Page We have addressed the landscape deficiencies and have added more diversity of shade trees. See the updated Landscape plans. 23. It is not clear whether this criterion is met. Staff recommends the Board require the applicant to provide a computation demonstrating compliance with this criterion prior to closing the hearing. We have calculated there is 84,488 sq ft of parking area of which there are 13,812 sq ft of landscaped islands. This is well over the 10% requirement of 8,449 sq ft of landscaped islands. 24. 270 parking spaces are provided, requiring 54 shade trees. Staff considers there are 34 trees which constitute parking lot shade trees, and recommends the Board require the applicant to provide an exhibit demonstrating this criterion is met. We have added additional shade trees surrounding the northern parking area and now meet this requirement of 54 deciduous trees, on or near the edge of parking, for the 270 spots. The reason we did not add trees along the north and western limits of the main parking area was to respect the neighbors request to not block their views to the mountains. 25. As noted above and based on recommendations of the City arborist, Staff recommends the Board reduce the reliance on maples on the plan. As mentioned above, we have adjusted the species selection of trees. See the updated Landscape plans. 26. Staff recommends the Board ask the applicant to make a presentation on how they are complying with this criterion, including screening from proposed site lighting to all adjoining residential properties, including the O’Brien Eastview development to the north. We have provided a mix of evergreen and shade tree planting bordering the residential properties on the west and north sides of the site in addition to landscape berms and grade changes that will comply with the screening requirements including screening proposed on site lighting. 27. Very limited landscaping is proposed in the front yard. It appears the applicant has attempted to avoid plantings within the front setback. Staff recommends the Board require the applicant to improve compliance with this criterion. The proposed front yard landscaping includes shade and evergreen trees with a meadow seed mix for maintaining an agrarian character reminiscent of the site’s past use. There is ledge Ms. Marla Keene, Planner University of Vermont Medical Center – Outpatient Surgery Center Site Plan Application #SP-22-032 Additional Materials for DRB September 6, 2022 7 | Page outcropping which is an impediment. There are landscape plantings surrounding the courtyard. See the attached South Elevation. 28. Since the applicant has not met criterion 13.04D Front Yards, and compliance with 13.04C Screening and Buffering has some deficiencies, Staff recommends the Board require them to meet those criteria before allowing credit for perennials, grasses, and patio terraces. Further Staff recommends the Board require the applicant to provide a more detailed breakdown of what constitutes Patio Terraces” before determining which elements they will allow as contributing to the required minimum landscaping cost. We have updated the landscape budget to include additional plantings added. See the attached updated Landscape Budget. Please let me know if you have questions about these materials or need additional information. zz GRAVEL SCULPTURE 50' RIGHT OF WAY FOR FUTURE ROAD 50' RIGHT OF WAY FOR FUTURE ROAD POCKET PARK 10’ REC PATHPatient Parking 360360365365365365365EVEV370375375380380New BuildingOSC Tilley Drive 390385390395 385390380375390 400405x 369.2W395 400 40 5395395390385395400365380375370395375 400 405400390385EEELECELECELECELECEELECELEC EELEC ELEC 390385380375380GMGas meter390370390395380 385BBBBBBBENCH BENCH BENCHBENCHBENCHBENCHBENCHEELECELECELECELECFUTUREFUTUREFUTUREFUTUREBBB410BBENCH BENCH E380FDCHHHHEEL2L2 L2L2L2L2L2L2L2L2ELECFUTUREL1ELECFUTUREL1ELECL1ELECL1380380 375360hyd. #731hyd. #667hyd. #666New BuildingOSC390STOP Old Farm RoadSTOPSTOPSTOP360385385.2 xC-1.2C-1.3C-1.4C-1.5C-1.6C-1.7PROJECT:ORIG SUBMISSION:CURRENT:SHEET TITLE AND NUMBER:DATE DESCRIPTION∆C-1.0OVERALL SITE PLAN2021073 / KL project # 2120206/17/2022OUTPATIENT SURGERY CENTERUVM HEALTH NETWORK LOT 6; TILLEY DRIVESOUTH BURLINGTON, VT 05403 CIVIL ENGINEERINGKREBS & LANSING164 Main St.Colchester, Vt. 05446802-878-0375Structural EngineeringEngineering Ventures, PC208 Flynn Ave.Suite 2A802-863-6225MEP EngineeringConsulting Engineering Services811 Middle StreetMiddletown, CT 06457860-632-1682Landscape ArchitectureWagner Hodgson7 Marble AvenueBurlington, VT 05401802-864-0010Sustainability ConsultantThornton Tomasetti14 York StreetSuite 201207-245-6066888.781.8441 © 2021 E4H - Environments For Health, LLC e4harchitecture.com 185 Talcott Rd, Williston, VT 05495802.878.884102/28/2022 SD Pricing PackageFOR COORDINATION ONLYNOT FOR CONSTRUCTIONSEE NOTES ON SHEET C-2.0PERMIT PLANS07/22/2022 Design Development08/11/2022 363360360365365365365365EVEV370375375380380New BuildingOSCDrop-offLoading Docks Tilley Drive ONE WAYPick-upNew Sidewalkretaining wall390391392393394 387 3823833843853873883893903913922 ADA Spaces 388389 39 5 3973 9 8 394Patio 383382379378x368.1 top berm x380.1 top berm378bike rack area384385386387388389390391383CB 8CB 7380381CB 46377New Concrete Sidewalk New Sidewalk PatioCB23CB28CB31CB29CB33CB6CB 4CB17CB16CB13CB22375CB39CB11382392393394394 390387 400401402403404405396New 5' concrete sidewalkW397398399395 396 397 398 399 400 401 402 403 40440 5 CHILLER service entranceRelocated windmill396CB20CB35CB34CB26392394396395391391392393394395396397398393 391CB12390386385 Domestic water service (6") Sprinkler service(6") CHILLER 394393383392393395394Stop barNew SMh ANew 8" x 6"tappingsleeve andvalve393400ForebayWetland Cell 1-1Wetland Cell 1-2363367363364365366367368368366365362ForebayWetland Cell 2-1Wetland Cell 2-2380375370378399401 402399395398397396375CB24CB43CB44CB36CB37CB42400 405396400402 407390385381retaining wallCB21CB19New SMh BDMh #2DMh #1CB9CB 10394 Knee-wall retaining wallCB27CB40CB41EEELECELECELECELECEELECELECNew HD concrete padCB 32EELEC ELEC 403 389 393390385387381380378376375380GMGas meter404390Stopbar368 370CB 2YD 1YD 2Patio381390395394STMh 2STMh 1376CB14380 383384387385393TRANS.SNOWSTORAGESNOW STORAGESNOWSTORAGECB 15BBBBBBBENCH BENCH BENCHBENCHBENCHBENCHBENCHEELECELECELECELECFUTUREFUTUREFUTUREFUTURESNOWSTORAGEBBB+416.1+396+397+3983 9 5 3 9 4 3 9 3 3 9 0 38 7 416410414415BBENCH BENCH Estaff entranceNew 8"x8"tappingsleeve andvalveNew 8" DI waterservice(Private)380FDCLandscape BermNew Multi-Use concrete padSee Structural CB25(Relocate)New gravel shoulderCB38New HD concrete padCB 1CL1CL1CL1CL1CL2CL2CL2SIGNSL1SL1SL1SL1SL1SL1SL1SL1SL1SL2SL2SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL3SL4SL4SR1SR1SR1SR1SR1SR1SR1SR1SR1SR1SR1SR1SR1SS1SS1SS1SS1SS1SS1SS1SS1SS1SS1SS1SS1SS1SS1SS1SS1SS1SW1SW1SW1SW1SW1SW1SW2SW2SW2SL5SL5SL5SL5SL5HHHH(4 ) 4 i n c h c o n d u i t s (4) 4 inch conduits(4) 4 inch conduits (2) 4 inch conduits (3) 4 inch conduitsTele-data Oxygen service New 6" DIwater serviceFD FD CB30CB33CB 315" SDR35 stormEEL2L2L2L2L2L2L2L2L2L2ELECFUTUREL1ELECFUTUREL1ELECL1ELECL1391393392380377378379380 ONE WAY375360hyd. #731hyd. #667hyd. #666386387Gravel Wetland #2EMER.

These activities may disrupt the wetlands system and may require some vegetationre-establishment. The riser pipes may clog and will require annual clean-out (it should be done in the winter timewhen one can walk on the wetland).·First Year Post-Construction: Inspection frequency should occur after every major storm in the first yearfollowing construction.oInspect that the system drains within 24-48 hours.oThe plants may need watering if necessary during the first growing season. Revegetate if the vegetationis poorly establishing.oIdentify areas of erosion and make timely repairs.oCheck all inlets, outlets and subdrains for proper functioning. Risers may need to be cleaned.·Post-Construction: Inspection frequency should occur at least every 6 months and after every major storm.Activities are expected to include:oCheck the basin for a dense root mat establishment of wetland vegetation.oCheck and clean the risers if there is evidence of standing water, discolored water or accumulatedsediments in the cells.oCheck and clean the forebay for sediments, trash and debris. When sediments have accumulated toa depth of 12 inches, standing water is persistent or wetland vegetation become established, theforebay will need to be excavated and reformed.oVerify that the cells drain within 24-48 hours. Sediment will need to be removed when an accumulationof 4 inches is evident over the wetland surface.oCheck and clean all outlets and overflow spillway if blocked or there is evidence of structural damage orerosion.oRemove decaying vegetation, litter and debris.oCheck for foreign species. Particular care must be used to avoid the unintended introduction of invasivespecies such as purple loosestrife (Lythrum salicaria) and common reed (Phragmites australis). It isrecommended that a qualified wetland biologist be consulted when these are found in the area of thegravel wetland.GRAVEL WETLAND MAINTENANCE NOTES:2021073 / KL project # 2120212"08/11/2022PERMIT PLANS06/17/202202/28/2022 SD Pricing Package07/22/2022 Design Development 888.781.8441 © 2021 E4H - Environments For Health, LLC e4harchitecture.com 185 Talcott Rd, Williston, VT 05495802.878.8841FOR PERMIT REVIEWNOT FOR CONSTRUCTION2021073 / KL project # 21202PROJECT:ORIG SUBMISSION:CURRENT:SHEET TITLE AND NUMBER:DATEDESCRIPTION∆C-4.8CIVIL DETAILSOUTPATIENT SURGERY CENTER UVM HEALTH NETWORK LOT 6; TILLEY DRIVE SOUTH BURLINGTON, VT 05403 CIVIL ENGINEERINGKREBS & LANSING164 Main St.Suite 201802-878-0375Structural EngineeringEngineering Ventures, PC208 Flynn Ave.Suite 2A802-863-6225MEP EngineeringConsulting Engineering Services811 Middle StreetMiddletown, CT 06457860-632-1682Landscape ArchitectureWagner Hodgson7 Marble AvenueBurlington, VT 05401802-864-0010Sustainability ConsultantThornton Tomasetti14 York StreetSuite 201207-245-60668"Base BlockMiddle BlockMiddle BlockMiddle BlockTop Block8"varies - see site planBOX BEAM GUARD RAILSPECIFICATIONS:PlanSection1" x 45° ChamferConduitAnchor BoltsConduit, typ.Anchor BoltsPVCPVC 24"6 ft. min.Bury depthNOTE:See Electrical Plans for electrical,conduit, light pole bolt pattern,and grounding design.- Concrete Minimum Strength 5000psi @ 28 days- Reinforcement per Specification.

Site Amenity Requirement According to Section 14.06C of the South Burlington LDR’s, the site amenity area required for the Outpatient Surgery Center (OSC) project is 6% of non-residential building gross floor area. The gross floor area of the OSC building is 84,006 sq. ft., which would equate to a minimum of 5,040 square feet of site amenity area that needs to be provided. The following information identifies how the OSC Project meets the Civic Space / Site Amenity Requirements identified in Article 11B. 1. Pocket Park In order to meet the site amenity requirement, a pocket park is proposed on the northern end of the site bordering the future roadway connection from the Eastview Development, the future driveway connection from the OSC parking areas, and the proposed recreation path. The pocket park is approximately 5,200 square feet in size and is bisected by the proposed recreation path. The oval shaped space is defined by granite chunk benches and landscaping surrounding the perimeter with lawn on the west side and gravel area on the east side of the recreation path. There is a sculpture area and landscape plantings consisting of shade trees, shrubs, ornamental grasses, and perennials. The definition of a Pocket Park is “a small, landscaped green space, designed, and managed as an outdoor living “room” for more limited passive recreation and social interaction. Intended to serve the immediate area (street, block) within walking distance (1/4 mile), including adjoining residences and businesses. Typically located mid-block, or on a street corner. Especially suited for infill development in neighborhoods that lack open space.” Amenities that can be included are a path, seating area, trees, gardens, community garden, playground, and public art. The minimum size for a pocket park is 2,000 square feet and maximum is 20,000 square feet. It typically has frontage on one or more streets and may be spatially defined by attractive fencing and landscaping that define the space. The proposed pocket park is a landscaped green space that is designed for complementing the recreation path by providing an area for people to stop and relax. It offers benches for sitting under shade trees with shrubs, perennials, and ornamental grasses. Bordered by the future roadway connection from the Eastview Development to the future City road on Lot 2 on the north and the future drive connection from the OSC parking area to the west with the UVM Medical Center Outpatient Surgery Center Section 14.06C Site Amenity Requirements September 2, 2022 2 recreation path bisecting it, pedestrians from the existing and future residential neighborhoods and commercial businesses will have a passive recreational park to visit and use. The project also includes an outdoor courtyard space located on the south side of the building for patients and visitors and an outdoor patio area for employees. However, these are not counted towards meeting the Site Amenity requirements for this project. In summary, the OSC Project is providing a pocket park which meets the site amenity requirements identified in Section 14.06C of the City of South Burlington LDR. The pocket park is approximately 5,200 square feet which exceeds the required site amenity 5,040 square feet for this Project. We believe this proposed pocket park meets the Site Amenity requirements for the UVM Medical Center Outpatient Surgery Center project.

Trip Generation Estimates For the proposed 84,006 sf Outpatient Surgery Center, WCG developed a site-specific trip generation estimate rather than using ITE ratios for land use categories such as Hospital, Clinic, and Medical/Dental Office. BFJ concurs with WCG’s conclusion that the ITE uses are not comparable enough to the trip generation of the proposed Outpatient Surgery Center. WCG’s custom trip generation is based on staffing models provided by UVM MC and the 24-Hour staff/ patient arrival and departure estimations. WCG assumes a total of 215 employees, 12 operating rooms, and an estimated 112 patients per day. Note that the surgical center would effectively operate from 5:50 AM when the first shift of professional staff arrive to 7:30 PM when final professional staff leave. WCG presents the following vehicle trip generation for the Outpatient surgery center:  AM Peak Hour: 126 trips  PM Peak Hour: 129 trips BFJ agrees with this methodology and finds the peak-hour traffic generation estimates to be reasonable. Internal Capture Assumptions WCG states that some of the traffic generated by the outpatient surgery center will remain internal between the surgery center and the near-by Red Barn Market & Deli, the argument being that the trips made between the two sites regardless of travel mode will not travel along Tilley Drive and are considered internally captured. We disagree with this assumption, since the deli is an existing use with its existing traffic generation. Today’s trips to or from the deli are not likely to divert to the surgery center and any trips to or from the surgery center that stop over at the deli would constitute additional trips to the deli. If we had the reverse situation where the surgery center existed and the deli was added the internal capture would be more real. Some of the future staff and doctors, and possibly some visitors/patients may walk to the deli to purchase coffee, snacks or lunch, however, these trips would be limited in their numbers and would mostly occur during non-peak hours. We recommend that the BUCKHURST FISH JACQUEMART, INC. 115 FIFTH AVENUE NEW YORK, NY 10003 T. 212.353.7474 F. 212.353.7494 applicant should not take any credit for internal capture. By the way if the applicant were to take credit for internal capture the numbers of credited trips have to be the same inbound and outbound. TDM Trip Reduction Credit Trip generation reductions have been applied to the analysis based on VTrans TDM guidelines. BFJ reviewed these guidelines and raises the following concerns:  WCG assigns a 3% credit in relation to parking supply management. We do not see how a reduced parking supply may be reasonable in this case and question the validity of this credit. Any shared parking with the nearby deli would not reduce traffic generation.  A 9% credit was assigned in relation to joining a TMA (small site, >100 workers). TMA services include ridematching, vanpool support, guaranteed ride home, financial incentive/rewards programs, transit subsidies/discounts. We do not believe that this credit to be assigned to the patients visiting the clinic nor to the doctors who are not on a regular schedule and come for a few hours on a particular day. We recommend that this credit be reduced to 5% and that the TMA membership becomes condition of the approval. Date: 27 May 2022 To: Dave Keelty, UVM Medical Center Director Facilities Planning and Development From: Corey Mack, PE Subject: UVM Medical Center Outpatient Surgery Center Transportation Impact Study WCG has prepared a transportation impact study (TIS) for the proposed University of Vermont Medical Center (UVMMC) Outpatient Surgery Center located on Lot 6 of the Mountain View Office Park along Tilley Drive in South Burlington, VT. The proposed Outpatient Surgery Center consists of an 84,006 square foot building containing twelve operating rooms, as well as pre- surgery and post-operation recovery spaces, a sterile reprocessing area, a material handling area, and other associated medical service and administrative functions. The site will access Tilley Drive through an existing driveway shared with the Red Barn Market & Deli; Tilley Drive intersects with Hinesburg Road / VT-116 approximately 300 feet west of the shared driveway. This TIS includes the following analysis: 1. Project Parameters, including a project description and trip generation estimate 2. Existing Roadway Conditions, describing the existing road network and crash history 3. Traffic Projections, including traffic adjustments, trip distribution, and other development volumes 4. Capacity and Warrant Analyses, documenting estimated operating conditions 5. Bicycle, Pedestrian, and Transit Access, evaluating non-motorized access to the site 6. Impact Fee Estimates, for Act 145 and City of South Burlington impact fees. SUMMARY OF FINDINGS AND RECOMMENDATIONS • The UVMMC is proposing to construct an 84,006 SF Outpatient Surgery Center. The proposed facility will conduct only outpatient surgical procedures, with no clinical, diagnostic, administrative, or other medical appointment or walk-in services. • The facility may serve approximately 112 patients per day, with an estimated staff of 215 physicians, nurses, students, and other medical system professionals and associated staff. • Based on the staffing and patient arrival and departure models, the proposed site is estimated to generate 103 new external vehicle trips in the AM peak hour, and 110 new external vehicle trips in the PM peak hour. • There are no state designated High Crash Locations within one road mile of the proposed site. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 2 • The proposed driveway location, utilizing the existing Red Barn Market & Deli driveway opposite 62 Tilley Dr, exceeds required minimum and design target sight distances for safe and efficient vehicle access. • Traffic modeling scenarios predict that there will be no unreasonable congestion associated with the proposed traffic generated from the project. The traffic congestion performance measures, including the Levels of Service and volume to capacity ratios, meet applicable VTrans policy guidelines. • The proposed driveway, utilizing the existing Red Barn Market & Deli driveway opposite 62 Tilley Dr, is expected to perform well below the congestion and capacity thresholds. • An eastbound left turn lane on Tilley Drive into the proposed shared driveway is not warranted by volume or recommended by engineering judgment. • The proposed site includes substantial bicycle and pedestrian accommodation and electric vehicle charging infrastructure. No significant impacts to the transportation system have been identified, and no mitigation is warranted or recommended. • The proposed site may be assessed an Act 145 Transportation Impact Fee of $33,722, and a City of South Burlington Transportation Impact Fee of $109,985. Based on the analysis conducted for this report, it is our professional judgement that the proposed project will not cause or exacerbate any unreasonable congestion or unsafe conditions on the local roadway network and will not unnecessarily or unreasonably endanger the public's investment in any local roads, highways, or related infrastructure. 1. PROJECT PARAMETERS The proposed UVMMC Outpatient Surgery Center site is illustrated in Figure 1. As detailed in the proposed project schematic design package: “[UVMMC] is planning to construct a new Outpatient Surgery Center in order to replace the surgical capacity formerly available at the Fanny Allen Campus and handle a wider and more sophisticated variety of surgical procedures and increased projected future surgical volume anticipated over the next 10 years. The development program for the proposed +/- 84,006 GSF building will include 12 operating rooms as well as adjacent pre-surgery and post-operative recovery spaces to be located on the ground level floor. Patient and staffing models provided by UVMMC indicate the site will conduct 112 surgical procedures on a peak day with 215 employees on site. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 3 FIGURE 1: PROPOSED SITE PLAN LANDSCAPE SCHEMATIC, FEBRUARY 2022 UPDATE WITH LATEST SITE PLAN WHEN AVAILABLE UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 4 Additional features described in the design package include: • Registration area with adjoining waiting room • Sterile reprocessing area • Material handling area • Separate employee entrance and support facilities, including changing area, locker and shower rooms, and lactation room • Conference room / classroom for staff meeting and training activities • 270 parking spaces As an outpatient surgical facility, the site is not intended for overnight care. Meal services are not included for patients or employees. The site will not provide clinical, diagnostic, administrative, or any other medical appointments or walk-ins. There will be no on-site retail pharmacy. All pre- and post-surgical appointments will be conducted at other UVMMC sites. The only services to be performed at the proposed site are outpatient surgical procedures. Estimated Trip Generation Trip generation refers to the number of vehicle trips originating at or destined for a particular land use development. Often, data from the Institute of Transportation Engineers (ITE) can be applied to estimate base vehicle trip generation associated with the former and proposed land uses. Base vehicle trips are the total estimated vehicle trips prior to any reductions associated with internal capture, pass-by, or transportation demand management (TDM) practices. The ITE Trip Generation Manual, 11th Edition includes trip generation data for several types of medical facilities, including land use code (LUC) 610: Hospital, LUC 630: Clinic, and LUC 720: Medical Dental Office. Given the specific outpatient surgical nature of the proposed facility, these broad land use descriptions do not represent the specialized services to be performed at the proposed site. To estimate trip generation, WCG evaluated the staffing and patient levels proposed by UVMMC. UVMMC identified a proposed staffing level of 215 employees with 112 daily patients for the 12 operating room facility. The staffing and patient models identified arrival and departure times for both patients and staff. In addition, WCG added trips for estimated patient and employee drop-offs and pick-ups, mid-day employee departures and returns, and hourly support and delivery vehicles entering and exiting the site. The overall arrival and departure trip generation model is presented in Attachment A. The resulting estimated AM peak hour, PM peak hour, and average weekday base trip generation of the proposed site is documented in Table 1. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 5 TABLE 1: ESTIMATED BASE VEHICLE TRIP GENERATION OF THE PROPOSED UVMMC OUTPATIENT SURGERY CENTER While the Outpatient Surgery Center is being developed as a standalone site, the proximity of the nearby Red Mill Market & Deli creates a complimentary land use pair. Some trips destined to or originating from the Outpatient Surgery Center will also stop at the Market & Deli. Trips made between the two sites regardless of travel mode (walk, bike, drive or other) will not travel along Tilley Drive and are considered internally captured. This capture of trips internal to the site has the net effect of reducing vehicle trip generation between the overall development site and the external street system (compared to the total number of trips generated by comparable land uses developed individually on stand-alone sites). Internally captured trips have been estimated using the recommended methodology in the ITE Trip Generation Handbook1 and are shown in Table 2. TABLE 2: INTERNALLY AND EXTERNALLY GENERATED TRIPS AT THE PROPOSED UVMMC OUTPATIENT SURGERY CENTER The Lot 6 Tilley Drive location has been specifically selected by the applicant due to the site’s location near other UVMMC facilities on Tilley Drive (62 Tilley Drive, 118 Tilley Drive, and 180 Tilley Drive), existing transit service, and a robust existing and planned bicycle and pedestrian path system. These physical features, coupled with UVMMC’s commitment to transportation demand management (TDM) practices, are likely to result in reduced vehicle travel to the site. Using VTrans TDM Guidance2, the net reduction in external trip generation can be estimated by accounting for the physical infrastructure on and near the site, coupled with organizational TDM policies. Applicable trip generation reductions are compiled in Table 3. 1 NCHRP Report 684 - Enhancing Internal Trip Capture Estimation for Mixed-Use Developments 2 VTrans Transportation Demand Management (TDM) Guidance, February 2016 Daily Base Description Size Unit Enter Exit Total Enter Exit Total Total UVMMC OSC - Custom 84.1 KSF 113 13 126 15 114 129 918 AM Peak Hour PM Peak Hour Base Base Internal External Description Enter Exit Total Enter Exit Total Enter Exit Total Enter Exit Total Total Total UVMMC OSC - Custom 4 5 9 109 8 117 1 3 4 14 111 125 44 874 Daily ExternalInternal Internal External AM Peak Hour PM Peak Hour UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 6 TABLE 3: ELIGIBLE TRIP GENERATION REDUCTIONS FROM TDM FEATURES Of the estimated external trips calculated in Table 2, a portion of them would be addressed through the TDM features in Table 3. Table 4 indicates the portion of the external trips that would be addressed through the TDM features, along with the resulting external vehicle trips that would then interact with the surrounding road network. TABLE 4: EXTERNAL VEHICLE AND TDM-MITIGATED TRIPS The total estimated external vehicle trip generation in the AM peak hour, PM peak hour, and average weekday is summarized in Table 5. TABLE 5: TOTAL ESTIMATED EXTERNAL VEHICLE TRIP GENERATION ASSOCIATED WITH THE PROPOSED DEVELOPMENT SITE Consultation with City of South Burlington and VTrans Development Review Services resulted in a study area which included the site driveway and all intersections receiving 75 trips or more in the peak hours, consistent with standard VTrans TIS Guidelines. The Study area includes the proposed site driveway on Tilley Drive and the intersections of VT-116 with Tilley Drive, Old Farm Road, and Kennedy Drive. These intersections relative to the project area are illustrated in Figure 2.

EXISTING ROADWAY CONDITIONS The proposed project is located on Lot 6 of the Mountain View Business Park, a commercial subdivision along Tilley Drive in South Burlington, Vermont. The site is located on the north side of Tilley Drive, with a single access point which is shared with the Red Barn Market & Deli. Figure 2 illustrates the location of the proposed site relative to the existing and planned future local roadway network. FIGURE 2: EXISTING SITE AND STUDY INTERSECTIONS RELATIVE TO LOCAL ROAD NETWORK Existing Road Network Tilley Drive is a Class 3 Town Highway (TH-215) with one lane in each direction and a total curb-to-curb width of 30 feet. There is an 8-foot asphalt shared use path on the north side of Tilley Drive. The speed limit of Tilley Drive is not posted. There are no centerline or edge line markings along the road. Hinesburg Road (VT-116) is a state highway under Vermont Agency of Transportation jurisdiction. VT-116 is classified as a Principal Arterial and is included in the Federal Aid Highway System. The width of VT-116 varies throughout the study area between 31 feet and 48 feet, with flares for turn lanes at primary intersections. The speed limit of VT-116 is 40 mph UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 8 south of I-89, 35 mph from I-89 to Kennedy Drive (through the Tilley Drive intersection), and 30 mph north of Kennedy Drive to its terminus at Williston Road (US-2). A sidewalk is present on the west side of VT-116 north of Tilley Drive through Kennedy Drive to Williston Road. Existing off-road shared use paths are present along Tilley Drive and through many adjacent roadways, including Community Drive, Kimball Ave, Eldridge Street, and Kennedy Drive, with additional paths proposed to be constructed on adjacent lots in the Hillside and Eastview developments along Old Farm Road. Future Road Network City of South Burlington planning documents have identified three significant future roadway projects, illustrated in Figure 2: Tilley Drive extension to Community Drive, the I/C Road between Tilley Drive and Kimball Avenue, and a new interchange with I-89 at Hinesburg Road and Tilley Drive (Exit 12B). Proceeds from the City’s Transportation Impact Fee are assigned to fund the Tilley Drive Extension project (among others), however there is no current schedule for design, permitting, or construction of the roadway extension. The I/C Road will be constructed from Kimball Avenue to the Mountain View Business Park property line as part of the adjacent Hillside development along Old Farm Road. There is no scheduled project to design, permit, or construct the remaining portion of the I/C Road or the Exit 12B interchange. Study Intersections The Study Intersections are illustrated in Figure 2 and include the following (from north to south): 1. Hinesburg Road (VT-116) & Kennedy Drive. VT-116 and Kennedy Drive are both principal arterials, with Kennedy Drive under local jurisdiction. The roadways meet at a signalized intersection with permissive left turn phasing on all approaches, and a northbound right overlap phase. The northbound and southbound approaches of VT-116 include one dedicated left, through, and right turn lane, and the eastbound and westbound Kennedy Drive approaches include two through lanes, with one dedicated left and right turn lane. The pedestrian phase is exclusive. 2. Hinesburg Road (VT-116) & Old Farm Road. VT-116 is uncontrolled in both approaches to Old Farm Road. Old Farm Road is a local road under local jurisdiction and is stop controlled with one approach lane to VT-116. A northbound right turn lane and a single through lane in each direction is present on VT-116. 3. Hinesburg Road (VT-116) & Tilley Drive / John Fay Road. Tilley Drive and John Fay Road intersect with Hinesburg Road / VT-116 approximately 300-feet west of the existing Red Barn Market & Deli driveway. The westbound approach of Tilley Drive is stop controlled and consists of a dedicated left turn / through lane and right turn lane, but with no lane markings the length of turn lane is unclear. John Fay Road consists of a single stop controlled eastbound approach lane. The VT-116 approaches are UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 9 uncontrolled, with dedicated northbound left turn, through, and right turn lanes, and a dedicated southbound left turn lane and shared through / right turn lane. The Hinesburg Road & Tilley Drive / John Fay Road intersection is under construction for signalization, with construction scheduled to be completed in the Spring / Summer of 2022. The signalized intersection is expected to allow permissive / protected southbound left turns. The project will include a pedestrian crosswalk. The pedestrian crossing phase is expected to be concurrent with the adjacent vehicular phases. 4. Tilley Drive and Shared Site Driveway / 62 Tilley Drive Driveway. Tilley Drive is uncontrolled in both approaches to the existing site driveway / 62 Tillet Drive driveway intersection. The intersection is approximately 300-feet east of VT-116. The northbound 62 Tilley Drive approach and southbound existing site driveway are both stop controlled, with one lane serving all turning movements. Crash History WCG reviewed the most recent high crash location (HCL) report prepared by VTrans using 2012-2016 crash data. According to the HCL report, there are no state-designated HCL intersections or segments near the project site, illustrated in Figure 3. The nearest HCLs are located along Williston Road and Dorset Street, over 1 mile away. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 10 FIGURE 3: NEAREST STATE DESIGNATED HIGH CRASH LOCATIONS TO THE PROJECT SITE WCG reviewed reported crashes from January 1, 2017 through December 31, 2021 along Hinesburg Road within ¼ mile of Tilley Drive and Old Farm Road, and along the entire length of Tilley Drive. These crashes are shown in Figure 4. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 11 FIGURE 4: REPORTED CRASHES ALONG TILLEY DRIVE AND ALONG HINESBURG ROAD WITHIN 1/4 MILE OF OLD FARM ROAD AND TILLEY DRIVE 19 crashes were reported within these limits over five years. Three of these crashes (16%) resulted in an injury; the remaining 16 crashes were property damage only. Other notable crash data statistics: • Crash type: six (32%) rear end, three (16%) left turn related, one (5%) right turn related, one (5%) sideswipe, eight (42%) undefined • Surface condition: three (16%) crashes on snow surface, one (5%) crash on wet surface, 15 (79%) dry or undefined • Season: six (32%) crashes in summer, six (32%) in fall, four (21%) in winter, three (16%) in spring At the Hinesburg Road & Tilley Drive / John Fay Drive, there were 8 reported crashes. Six of these crashes occurred in 2018 or 2019, prior to the installation of the northbound and southbound left turn lanes into Tilley Drive. Two crashes occurred in January 2020 following the intersection widening. One crash was a rear end on the Tilley Drive approach, and the second was left turn broadside crash from Tilley Drive; both of these crashes appear to be correctable by signalization. The signal on Tilley Drive is expected to be operational prior to occupancy of the proposed project. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 12 Sight Distance As defined in the 2018 publication A Policy on Geometric Design of Highways and Streets, from the American Association of State Highway and Transportation Officials (AASHTO), sight distance is the “the length of roadway ahead that is visible to the driver.”3 Sight distances of sufficient length are necessary at all points along a roadway to ensure vehicles can safely stop or avoid colliding with potential obstructions or other vehicles on the roadway. Standard practice in assessing intersection safety and operations involves measuring two separate sight distances – stopping sight distance and intersection sight distance. Stopping sight distance (SSD) is the visible distance along a roadway between an advancing motorist and a potential obstacle in the roadway. It is measured from a point representing the approaching driver’s eye and a point representing an obstacle in the roadway.4 Stopping sight distances of adequate length are needed along all roadways, both at and away from intersections, so that drivers travelling at design speeds can react to potential obstacles and safely brake to avoid collisions. Design minimum stopping sight distances are calculated based on factors such as design speed, response times, and grades as reported in the 2018 Policy on Geometric Design of Highways and Streets.5 Intersection sight distance (ISD) is the distance available along the major road travelled way corresponding with the maximum visibility between an advancing motorist on the major road and an entering motorist on an intersecting minor road. It is measured between a point representing the advancing driver’s eye above the major road and a point representing the entering driver’s eye above the intersecting road.6 The 2018 Policy on Geometric Design of Highways and Streets states that the available intersection sight distance should be at least equal to the required stopping sight distance along the major road. 3 American Association of State Highway and Transportation Officials, A Policy on Geometric Design of Highways and Streets, Seventh Edition (Washington D.C.: American Association of State Highway and Transportation Officials, 2018). Page 3-2. 4 As noted in the 2018 Policy on Geometric Design of Highways and Streets (page 3-15), the height of the driver’s eye is assumed to be 3.5’ above the road surface and the height of a potential obstacle is 2.0’ above the road surface. 5 American Association of State Highway and Transportation Officials, A Policy on Geometric Design of Highways and Streets, Seventh Edition (Washington D.C.: American Association of State Highway and Transportation Officials, 2018). Page 3-5 to 3-6. 6 As noted in the 2018 Policy on Geometric Design of Highways and Streets (page 3-16), the height of the driver’s eye of the approaching vehicle is assumed to be 3.5’ above the road surface of the major road and the height of the driver’s eye of the entering vehicle is assumed to 3.5’ above the minor road surface. The decision point offset from the travel way varies with sight conditions (page 9-38); in this case we assume the decision point is 15-feet from the travel way. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 13 “Sight distance is also provided at intersections to allow the drivers of stopped vehicles a sufficient view of the intersecting highway to decide when to enter the intersecting highway or to cross it. If the available sight distance for an entering or crossing vehicle is at least equal to the appropriate stopping sight distance for the major road, then drivers have sufficient sight distance to anticipate and avoid collisions.” However, when possible, it is desirable to have intersection sight distances that exceed the design minimum stopping sight distances to offer improved operations, such that major road traffic need not decelerate to accommodate entering traffic. “However, in some cases a major-road vehicle may need to stop or slow to accommodate the maneuver by a minor road vehicle. To enhance traffic operations, intersection sight distances that exceed stopping sight distances are desirable along the major road.” Based on an assumed 35-mph operating speed and a 3% westbound uphill grade along Tilley Drive, the design target intersection sight distance for turning traffic is 335 feet to the left and 390 feet to the right at the existing site driveway on Tilley Drive. The design minimum stopping sight distance is 240 feet in the westbound direction, and 260 feet in the eastbound direction. We measured intersection and stopping sight distances at the proposed site driveway. These sight distances are shown in the following figures, and the measured intersection and stopping sight distances are presented in the accompanying tables. FIGURE 5: DRIVER'S PERSPECTIVE 15-FEET FROM THE EDGE OF TRAVEL WAY AT THE EXISTING SITE DRIVEWAY ALONG TILLEY DRIVE TO THE EAST (LEFT) AND WEST (RIGHT) UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 14 TABLE 6: MEASURED SSD AND ISD AT THE EXISTING SITE DRIVEWAY Stopping Sight Distance Intersection Sight Distance Eastbound Westbound Left (to east) Right (to west) Required Minimum 260’ 240’ 260’ 240’ Design Target - - 335’ 390’ Measured 300’ >350’ >350’ 300’ Sight distances were clear to the intersection with Hinesburg Road, approximately 300 feet to the west. While this is below the design target, vehicles will be traveling at a lower speed after entering Tilley Drive from Hinesburg Road. The existing drive is located near a crest vertical curve, but both stopping and intersection sight distances were measured in excess of 350 feet. Measured sight distances exceed the required minimum and design target distances. 3. TRAFFIC PROJECTIONS This study relies upon design standards and analysis procedures documented in the Highway Capacity Manual 6th Edition,7 Trip Generation,8 A Policy on Geometric Design of Highways and Streets,9 Manual on Uniform Traffic Control Devices (MUTCD),10 Traffic Impact Study Guidelines,11 and the Vermont State Design Standards,12 which are the generally accepted traffic analysis references relied upon by traffic engineering professionals and VTrans for projects of this type in Vermont. Traffic Counts AM and PM peak hour turning movement counts were compiled for each of the four study intersections, with turning movement volumes at the site driveway inferred from the adjacent traffic count and trip generation estimates for their respective existing land uses. The source and date of each count is documented in Table 7. 7 Transportation Research Board, National Research Council, Highway Capacity Manual (Washington, DC: National Academy of Sciences, 2016). 8 Institute of Transportation Engineers, Trip Generation 11th Edition (Washington, D.C.: Institute of Transportation Engineers, 2021). 9 American Association of State Highway and Transportation Officials (AASHTO), A Policy on Geometric Design of Highways and Streets, 7th Edition (Washington DC: AASHTO, 2018). 10 American Traffic Safety Services Association (ATSSA), ITE, and AASHTO, Manual on Uniform Traffic Control Devices, 2009 Edition (Washington DC: FHWA, 2009). 11 Vermont Agency of Transportation, Policy and Planning Division, Development Review and Permitting Services, Traffic Impact Study Guidelines (April 2019). 12 State of Vermont Agency of Transportation, Vermont State Standards (Montpelier: VTrans, 1 July 1997).

Design Hour Volume Adjustment. The design hour volume (DHV) is based on automatic traffic recorder (ATR) count site D124 along Hinesburg Road south of Kennedy Drive and the VTrans Redbook DHV chart. ATR D124 was counted from 4/12/2021 through 4/18/2021 with an estimated 2021 AADT of 7,992 vpd. From the Redbook DHV Chart, the estimated DHV is 929 vehicles per hour. The contributory volumes from the Kennedy Drive and Old Farm Road intersections were used to estimate a DHV adjustment factor for each intersection, and the Tilley Drive intersection was balanced and adjusted to the Old Farm Road volumes. The resulting DHV adjusted volumes represent 2021 DHV conditions. 2. COVID Adjustment. Two continuous traffic count (CTC) stations were reviewed to evaluate AADTs in 2021 compared to pre-pandemic conditions in 2019: CTC D061 on US-2 in Williston, and CTC D040 on US-7 in Colchester. These two sites observed an average of 3.5% more traffic in 2019 than in 2021. This adjustment was applied to account for the effect of changes to background traffic as a result of the COVID pandemic in 2021. Following the COVID adjustments, the volumes represent 2019 DHV traffic conditions. 3. Annual Traffic Growth. The VTrans Redbook recommends a background traffic growth of 10% over 20 years. This results in an annual growth rate of approximately 0.5% per year. This annual growth rate was applied to the 2019 DHV volumes to represent the 2024 build year and 2028 future year (build + 5 years) scenario volumes. The total adjustments for each intersection are shown in Table 7. The adjusted traffic volumes were balanced around the Kennedy Drive intersection. Raw traffic volumes, adjustments, and balancing information can be found in Attachments C and D. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 16 Other Development Volumes WCG consulted with the City of South Burlington to identify planned and permitted but not yet constructed projects that may generate trips through the study area. Four projects were identified: • Tilley Drive Lot 5. Construction of a 54,868 SF medical office building is completed but not operational on Tilley Drive. The project was permitted under Act 250 land use permit 4C1153-7. • O’Brien Farm Hillside and Eastview Developments. The O’Brien Farm Hillside and Eastview projects are phased mixed-use developments located between Kimball Avenue, Old Farm Road, Hinesburg Road, and Kennedy Drive in South Burlington. Based on discussions with South Burlington Planning and Zoning staff, trip generation from the following development phases has been included in the background traffic network: o Hillside (Phases 1 & 2): Includes the full Hillside phases of development located along O’Brien Farm Road and Two Brothers Drive. o Eastview (Residential Only): Includes the residential component of the Eastview phase of development (R1 SF + C1-LR MF Residential Trips), which is located along both sides of Old Farm Road south of Kimball Avenue. Although some buildings in Hillside have been constructed and occupied and would be accounted for in the 2022 raw traffic counts, the entire estimated trip generation from land use permitting documents were added and distributed through the study intersections to be conservative for the phases noted above. • OnLogic Industrial Productions and Office Development. Construction of an industrial production campus is planned on Community Drive. • BETA Technologies Airport Campus Expansion. Construction of industrial, office, and ancillary employee services is planned on Williston Road. The estimated trip generation from land use permitting documents were added and distributed through the study intersections. The total cumulative trip generation and distribution for these other development traffic volumes is illustrated in Figure 6.

CAPACITY AND WARRANT ANALYSES Intersection capacity analyses were performed for the study area intersections. Analyses evaluated average control delay, Level-of-service (LOS), and volume to capacity (v/c) ratios, consistent with methodologies documented in the Highway Capacity Manual. Level-of-Service Definition Level-of-service (LOS) is a qualitative measure describing the operating conditions as perceived by motorists driving in a traffic stream. LOS is calculated using the procedures outlined in the Highway Capacity Manual, Sixth Edition: A Guide for Multimodal Mobility Analysis13 (HCM6). In addition to traffic volumes, key inputs include the number of lanes at each intersection, traffic control type (signalized or unsignalized), and the traffic signal timing plans, if applicable. The HCM6 defines six qualitative grades to describe the level of service at an intersection. Level-of-service is based on the average control delay per vehicle. Table 8 shows the various LOS grades and descriptions for signalized and unsignalized intersections. TABLE 8: LEVEL-OF-SERVICE CRITERIA FOR SIGNALIZED AND UNSIGNALIZED INTERSECTIONS LOS CHARACTERISTICS UNSIGNALIZED TOTAL DELAY (SEC) SIGNALIZED TOTAL DELAY (SEC) A Little or no delay ≤ 10.0 ≤ 10.0 B Short delays 10.1-15.0 10.1-20.0 C Average delays 15.1-25.0 20.1-35.0 D Long delays 25.1-35.0 35.1-55.0 E Very long delays 35.1-50.0 55.1-80.0 F Extreme delays > 50.0 > 80.0 The delay thresholds for LOS at signalized and unsignalized intersections differ because of the driver’s expectations of the operating efficiency for the respective traffic control conditions. According to HCM procedures, an overall LOS cannot be calculated for two-way stop-controlled intersections because not all movements experience delay. In signalized and all-way stop- controlled intersections, all movements experience delay and an overall LOS can be calculated. 13 The HCM6 does not provide methodologies for calculating intersection delays at certain intersection types including signalized intersections with exclusive pedestrian phases and signalized intersections with non NEMA-standard phasing. Because of these limitations, HCM 2000 and HCM 2010 methodologies are employed where necessary and as noted. UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 24 The VTrans policy on level of service is: • Overall LOS C should be maintained for state-maintained highways and other streets accessing the state’s facilities. • Reduced LOS may be acceptable on a case-by-case basis when considering, at minimum, current and future traffic volumes, delays, volume to capacity ratios, crash rates, and negative impacts resulting from improvements necessary to achieve LOS C. • LOS D should be maintained for side roads with volumes exceeding 100 vehicles/hour for a single lane approach (150 vehicles/hour for a two-lane approach) at two-way stop-controlled intersections. Volume to Capacity Ratio Definition The volume to capacity ratio (v/c) represents the sufficiency of an approach leg to accommodate the vehicular demand. According to FHWA: “As the v/c ratio approaches 1.0, traffic flow may become unstable, and delay and queuing conditions may occur. Once the demand exceeds the capacity (a v/c ratio greater than 1.0), traffic flow is unstable and excessive delay and queuing is expected.”14 VTrans does not have a v/c policy. Typically, v/c is used as an alternative indicator of performance, with preferred values below 0.95. Traffic Modeling Scenarios WCG built a traffic model using Synchro version 10 for the 2024 and 2029 adjusted intersection volumes for the AM and PM peak hours in the No Build and Build scenarios. The resulting performance measures are presented in Table 9 and Table 10. The results of the traffic modeling scenarios indicate that the proposed development will not cause any intersections to fall below the threshold of acceptable operations defined by VTrans. While the Kennedy Drive intersection operates at LOS D in all no-build scenarios, the v/c ratio is below 0.8, and the intersection is not within a high crash location, indicating that a reduced LOS can be acceptable in this urban location. The proposed project does not significantly change the overall delay, v/c ratio, or cause the level of service to reduce further at this intersection. All other intersections and individual approaches meet or exceed the VTrans LOS standards and all volume to capacity ratios are below 0.80, indicating the transportation network will continue to operate efficiently in the build scenarios. The proposed project build scenarios do not significantly increase delay or v/c performance measures compared to the no-build scenarios. 14 Federal Highway Administration (FHWA), Signalized Intersections: Informational Guide, 2004 UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 25 TABLE 9: 2024 TRAFFIC MODELING SCENARIO RESULTS TABLE 10: 2029 TRAFFIC MODELING SCENARIO RESULTS Intersections LOS Delay v/c LOS Delay v/c LOS Delay v/c LOS Delay v/c Hinesburg Rd & Kennedy Dr Overall D 38 0.72 D 41 0.75 D 43 0.76 D 43 0.78 EB, along Kennedy Dr D 38 0.75 D 43 0.78 D 41 0.66 D 41 0.66 WB, along Kennedy Dr C 34 0.59 D 38 0.59 D 44 0.78 D 44 0.78 NB, along Hinesburg Rd D 39 0.47 D 42 0.44 D 44 0.66 D 45 0.71 SB, along Hinesburg Rd D 39 0.72 D 42 0.74 D 42 0.43 D 45 0.46 Hinesburg Road & Old Farm Road WB, along Old Farm Road D 27 0.30 D 32 0.37 C 24 0.21 D 27 0.24 SB Left, along Hinesburg Rd A 9 0.01 A 9 0.01 A 9 0.00 A 10 0.00 Hinesburg Rd & Tilley Dr / John Fay Rd Overall B 12 0.52 B 13 0.59 B 16 0.50 C 22 0.50 EB, along John Fay Rd B 19 0.04 B 19 0.04 B 16 0.01 B 16 0.01 WB, along Tilley Dr C 21 0.04 C 21 0.05 C 22 0.19 C 29 0.22 NB, along Hinesburg Rd B 13 0.61 B 14 0.64 B 19 0.68 C 26 0.75 SB, along Hinesburg Rd A 10 0.59 B 12 0.72 A 9 0.14 B 11 0.16 Tilley Dr & Site Driveway / 62 Tilley Dr Driveway EB Left, along Tilley Dr A 7 0.03 A 7 0.03 A 8 0.02 A 8 0.03 NB, along 62 Tilley Dr Driveway B 13 0.02 B 13 0.02 B 13 0.09 C 16 0.11 SB, along Site Driveway B 11 0.08 B 11 0.08 B 10 0.06 B 11 0.19 2024 Scenarios AM Peak Hour No Build AM Peak Hour Build PM Peak Hour No Build PM Peak Hour Build Intersections LOS Delay v/c LOS Delay v/c LOS Delay v/c LOS Delay v/c Hinesburg Rd & Kennedy Dr Overall D 38 0.74 D 42 0.76 D 43 0.78 D 44 0.79 EB, along Kennedy Dr D 38 0.76 D 43 0.78 D 40 0.65 D 41 0.67 WB, along Kennedy Dr C 34 0.60 D 38 0.59 D 44 0.78 D 44 0.79 NB, along Hinesburg Rd D 41 0.49 D 43 0.46 D 45 0.69 D 45 0.73 SB, along Hinesburg Rd D 40 0.73 D 43 0.76 D 43 0.46 D 46 0.48 Hinesburg Road & Old Farm Road WB, along Old Farm Road D 29 0.32 D 34 0.39 C 25 0.22 D 28 0.25 SB Left, along Hinesburg Rd A 9 0.01 A 9 0.01 A 9 0.00 A 10 0.00 Hinesburg Rd & Tilley Dr / John Fay Rd Overall B 12 0.53 B 14 0.62 B 17 0.51 C 22 0.51 EB, along John Fay Rd B 19 0.04 B 19 0.04 B 16 0.01 B 16 0.01 WB, along Tilley Dr C 21 0.04 C 21 0.05 C 23 0.20 C 30 0.23 NB, along Hinesburg Rd B 13 0.62 B 14 0.66 B 20 0.69 C 26 0.76 SB, along Hinesburg Rd A 10 0.62 B 13 0.75 A 10 0.15 B 11 0.17 Tilley Dr & Site Driveway / 62 Tilley Dr Driveway EB Left, along Tilley Dr A 7 0.03 A 7 0.03 A 8 0.02 A 8 0.03 NB, along 62 Tilley Dr Driveway B 13 0.02 B 13 0.02 B 13 0.09 C 16 0.12 SB, along Site Driveway B 11 0.08 B 11 0.08 B 10 0.06 B 11 0.20 2029 Scenarios AM Peak Hour No Build AM Peak Hour Build PM Peak Hour No Build PM Peak Hour Build UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 26 In all scenarios, the proposed shared driveway location with the Red Barn Market and Deli is expected to operate well under capacity with no significant congestion or additional delay. The v/c ratio is 0.19, well below the 0.95 threshold indicating congestion, and all approaches that may experience delay will operate at LOS C or better. The proposed driveway will operate safely and efficiently. Left Turn Lane Warrant Assessment VTrans has identified the Kikuchi and Chakroborty (K&C) model as the preferred turn lane warrant analysis model, using 85% of the DHV15. Under the 2029 AM Peak Hour build volume scenario, an eastbound left turn lane is not warranted by volume at the Tilley Drive & Site Driveway intersection. With no history of crashes, sight lines that exceed required minimum and design targets, and no other turn lanes along Tilley Drive, a left turn lane is not recommended at the proposed drive location. 5. BICYCLE, PEDESTRIAN, AND TRANSIT ACCESS The proposed site is located adjacent to a shared use path system extending along Tilley Drive to Community Drive, Kimball Ave, and beyond offering both fitness and recreation opportunities from the site, as well as non-motorized access to adjacent land uses like the Red Barn Market & Deli and to surrounding communities. The proposed site is designed with exterior bicycle racks, secure interior bicycle storage, shower and locker facilities for employees, and other features to encourage bicycle access to the site. The site is connected to the shared use path with walkways. There is no fixed route transit stop along Tilley Drive. Green Mountain Transportation (GMT) operates the VT-116 Commuter Route between Hinesburg and Burlington; however with only two inbound and outbound trips per day, the route offers limited opportunity to serve medical staffing schedules. Special Services Transportation Agency (SSTA) operates a daily shuttle with on-demand front door access to each UVMMC building on Tilley Drive, and it is likely this service will be provided to the proposed Outpatient Surgery Center. UVMMC is a founding member of the Chittenden Area Transportation Management Association. Through their membership and ongoing commitment to healthy, active, and engaging transportation, UVMMC is committed to providing safe, reliable transportation infrastructure to their employees and patients. As noted earlier, the proposed Outpatient Surgery Center include enhanced facilities for people walking and biking to the site, plus electric vehicle charging stations to help achieve emission targets. 15 VTrans Traffic Impact Study Guidelines 2019, Page 39 UVM Medical Center Outpatient Surgery Center Transportation Impact Study 5/27/2022 27 6. IMPACT FEE ESTIMATES Two impact fees are likely to be assessed on this project: Act 145 Transportation Impact Fees, and City of South Burlington Transportation Impact Fees. Both fees are based upon new external vehicle trip generation in the PM peak hour associated with the proposed project, estimated at 110 trip ends documented in Table 5. Act 145 Fee Estimate The Act 145 Impact Fees were estimated using the same methodology as the permitted constructed Lot 5 development of the Mountain View Office Park on Tilley Drive. Using available intersection turning movement volumes, the contributing entering and exiting PM peak hour trip ends were proportionally directed through the transportation network to each eligible Act 145 project within five miles of the proposed development site. A reduction in the base Act 145 fee is warranted due to UVMMC’s participation in the Chittenden Area Transportation Management Association (10%). The resulting trips through each Act 145 eligible project and the estimated Act 145 fee is documented in Table 11. The Total Act 145 Impact Fee is calculated to be $33,722. TABLE 11: ACT 145 FEE CALCULATION City of South Burlington Transportation Impact Fee Estimate The City of South Burlington has implemented a flat transportation fee of $999.86 per PM peak hour trip end for non-residential developments; this fee may be adjusted for past or future tax payments. With 110 PM peak hour trip ends, the total estimated City of South Burlington Transportation Impact Fee is calculated at $109,985.

SUMMARY OF FINDINGS AND RECOMMENDATIONS • UVMMC is proposing to construct an 84,006 SF Outpatient Surgery Center. The proposed facility will conduct only outpatient surgical procedures, with no clinical, diagnostic, administrative, or other medical appointment or walk-in services. • The facility may serve approximately 112 patients per day, with an estimated staff of 215 physicians, nurses, students, and other medical system professionals and associated staff. • Based on the staffing and patient arrival and departure models, the proposed site is estimated to generate 103 new external vehicle trips in the AM peak hour, and 110 new external vehicle trips in the PM peak hour. • There are no state designated High Crash Locations within one road mile of the proposed site. • The proposed driveway location, utilizing the existing Red Barn Market & Deli driveway opposite 62 Tilley Dr, exceeds required minimum and design target sight distances for safe and efficient vehicle access. • Traffic modeling scenarios predict that there will be no unreasonable congestion associated with the proposed traffic generated from the project. The traffic congestion performance measures, including the Levels of Service and volume to capacity ratios, meet applicable VTrans policy guidelines. • The proposed driveway, utilizing the existing Red Barn Market & Deli driveway opposite 62 Tilley Dr, is expected to perform well below the congestion and capacity thresholds. • An eastbound left turn lane on Tilley Drive into the proposed shared driveway is not warranted by volume or recommended by engineering judgment. • The proposed site includes substantial bicycle and pedestrian accommodation and electric vehicle charging infrastructure. No significant impacts to the transportation system have been identified, and no mitigation is warranted or recommended. • The proposed site may be assessed an Act 145 Transportation Impact Fee of $33,722, and a City of South Burlington Transportation Impact Fee of $109,985. Based on the analysis conducted for this report, it is our professional judgement that the proposed project will not cause or exacerbate any unreasonable congestion or unsafe conditions on the local roadway network and will not unnecessarily or unreasonably endanger the public's investment in any local roads, highways, or related infrastructure.
