The development is to consist of 135 homes in single family, duplex, and three-family dwellings on nine (9) lots totaling 21.8 acres, nineteen (19) commercial development lots totaling 44.0 acres, one existing single family home, and 25.1 acres of undeveloped open space, 500 Old Farm Road. The Board reviewed the application on February 17, March 16, and April 20, 2021 and continued the hearing to complete review of the provided staff comments from those meetings and to allow the applicant to prepare responses. For this, the May 18, 2021 meeting, the applicant has provided an updated set of civil engineering drawings, open space plan, and phasing plan. This memo addresses previously discussed items for which a resolution has not yet been reached, and provides a review of the newly submitted materials. PHASING On April 20, the Board provided comments on the applicant’s previously proposed phasing plan, indicating that the applicant should modify their plan to include roadway improvements and connections to adjacent neighborhoods as an earlier phase. As a general comment, the applicant has proposed to tie phases to sales of homes. The sale of units is not a useable metric, as the Planning and Zoning office can only measure by zoning permits, not sales. 1. Staff considers the Board should require the applicant to change all triggers to be related to issuance of zoning permit applications. Phases 1 and 4: The applicant’s proposed phasing plan includes a greater than 7 acre “construction staging area” which they are proposing to open as the first step in the application, and a second nearly 7 acre “soil stockpile and fill area” which they are proposed to open “at discretion of Applicant as needed to facilitate materials storage.” On April 20, the Board and applicant agreed to additional discussion of the operation of these areas at the final plat stage of review. Staff considers the final plat decision may include additional restrictions on the use of these areas, potentially to include a maximum duration work can be stopped before the site is required to be restored, and therefore the approval of the phasing plan should be preliminary only. Phase 7: The applicant is proposing to construct the barn improvements no later than the sale of 15% of the homes, and be completed at the sale of homes 33-1 to 33-9. Staff considers this to be a very odd condition, as it mixes percent completion with specific units. #SD-20-40 2 2. Staff recommends the Board require the applicant to complete construction of the barn phase prior to a percentage of zoning permits, and recommends the Board determine what percentage would be appropriate. Phases 8 and 10: The applicant proposes to begin to relocate the north end of Old Farm Road and construct the connection to Hillside no later than the sale of 30% of the homes, and complete those two items no later than the sale of 45% of the homes. They estimate in their cover memo that 30% will occur at 28 months after issuance of the first zoning permit, and complete around 40 months after issuance of the first zoning permit. 3. Staff recommends the Board discuss this specific proposal with the applicant. In addition to the general concept proposed, Staff calls the Board’s attention to the applicant’s alternative proposal to build the connection to Hillside as part of the Hillside project. While this is an interesting offer, Staff notes it may require amendment of the Hillside master plan area, and therefore should not be considered a workable proposal unless the applicant submits such an application prior to final plat for Eastview. Phases 11 and 12: The applicant is proposing to construct the linear park between the residential area and the I/C area at completion of the abutting homes. The applicant is proposing to construct the dog park and playground area at the end of the cul-de-sac road at 50% of the projected trips from the C1-LR and R1 lands. 4. Staff considers at least one of these amenity areas should be tied to a percent completion of the currently proposed residential units rather than the proposed triggers in order to provide appropriate amenity areas for residents, and recommends the Board discuss what percentage they consider appropriate. Phase 16: The applicant is proposing to construct the trail at the east side of the I/C lots at 75% of the projected trip ends from the I/C lots. 5. Staff considers this to be a poor metric because the uses may never reach 75% of the projected trip ends, and instead recommends the trigger be tied to the zoning permit for a percentage of the lots accessed off I/C road, and recommends the Board discuss what percentage they consider appropriate. In addition, the phasing plan leaves out certain geographies from inclusion in any phase. While some of these are referenced with timelines for completion in the traffic analysis, they should be presented in a manner that is easy for all users to find and implement. Specifically: • Portions of the planned Kimball Ave recreation path are not included in any phase. Applicant should provide a proposed phasing for construction of the improvements • Planned Old Farm Road improvements are not included in any phase or on the Civil drawings. Planned Old Farm Road improvement include pedestrian, parking and travel way modifications. Applicant should modify their plans to include these elements and provide a proposed phasing for construction of the improvements. • The schematic plan for “Hillside Bike and Recreation Connectivity” shows the construction of a recreation path within portions of the Hillside PUD connecting to Eastview. Applicant should provide a phasing plan for construction of those improvements and confirm any permitting requirements. 6. Staff recommends the Board find that the phasing plan is generally satisfactory if the above elements are addressed, but that the Plan must be amended, clarified, and reviewed all together at final plat. TRANPORTATION AND CONNECTIVITY 15.18A(3) The project incorporates access, circulation and traffic management strategies sufficient to prevent unreasonable congestion of adjacent roads. In making this finding the DRB may rely on the findings #SD-20-40 3 of a traffic study submitted by the applicant, and the findings of any technical review by City staff or consultants. 15.12F(1) 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 “D” or better at full buildout. The applicant provided an updated traffic study dated March 30, 2021, for which the Board authorized a third party technical review. Both the study and technical review are included in the packet for the Board (traffic study appendices are available upon request). General observations on the updated traffic study follow. • the applicant has assumed the I/C area will be built out with medical/dental offices and commercial spaces. Industrial uses are lower traffic generators than the assumed uses. • the proposed ultimate conditions reflect full building of the R1 and C1-LR zoning districts and 50% buildout of the I/C area • in addition to the roadway improvements internal to the project, the following external intersections are proposed for improvement o Kennedy Drive/Kimball Ave – signal modifications o Kimball Ave at Old Farm Road – restriping to provide left turn lanes onto relocated Old Farm Road and signal installation when warranted o Kimball Ave at I/C Road - restriping to provide left and right turn lanes onto relocated Old Farm Road and signal installation when warranted The independent technical review provides the following recommended modifications to the applicant’s traffic study [paraphrased]. • reduce internal trip capture by half and reevaluate resulting traffic impacts. The internal capture estimate was based on large mixed use sites. Staff supports a reduction but would also recommend asking the technical reviewer for substantiation of their recommendation if the applicant or Board has any concerns. • evaluate single lane roundabout for Kimball Ave at Old Farm Road and at I/C Road. Staff recommends the Board consider whether to direct the applicant to complete these evaluations, and that any such evaluations should include an analysis of the impacts to large vehicle capacity. • delay installation of exclusive turn lanes until movements reach LOS E. Staff recommends that the Board require the applicant to work with Staff to develop a scheme with which they will reserve funds with each lot to fund construction of off-site improvements. • locate shared use paths and sidewalks with consideration for bus stops. Staff recommends the Board require the applicant provide an analysis of this at the next stage of review. • extend the shared use path on Old Farm Road from Hinesburg Road to Kimball Ave. As discussed at each hearing, Staff supports this connection. Staff’s recommendation for this path is provided later in this document. • provide only 1, instead of 3, RRFB’s (pedestrian beacons) on Old Farm Road. Staff considers the guidance for installation for RRFBs is not as well established as signal warrants, and therefore it is more #SD-20-40 4 difficult to determine whether they are warranted. Staff recommend that since they may be warranted or requested by residents they should be installed when project is constructed for perception & convenience. • combine figure 3 with figure 4 to get a comprehensive view of the pedestrian and bicycle amenities as they relate to the projected parks and community center. Staff supports this recommendation. 7. Staff recommends the Board review the above seven recommendations and determine which to require the applicant to address. 8. Staff further recommends the Board require the applicant to establish an executable plan for evaluating when each planned off-site improvement be required. 15.18A(8) Roads, recreation paths, stormwater facilities, sidewalks, landscaping, utility lines and lighting have been designed in a manner that is compatible with the extension of such services and infrastructure to adjacent properties. For Transect Zone subdivisions, this standard shall only apply to the location and type of roads, recreation paths, and sidewalks. 15.18A(9) Roads, utilities, sidewalks, recreation paths, and lighting are designed in a manner that is consistent with City utility and roadway plans and maintenance standards, absent a specific agreement with the applicant related to maintenance that has been approved by the City Council. For Transect Zone subdivisions, this standard shall only apply to the location and type of roads, recreation paths, and sidewalks. The applicant has provided more detailed information about the proposed roadways in response to comments and questions provided by the Board at previous hearings. Detailed comments developed in cooperation with the Department of Public Works are as follows. Sidewalks and Recreation Paths • It is the position of the City staff, City committees, and the independent technical review that a shared use path along the entire length of Old Farm Road is an important element of the proposed project. The Board noted on April 20 that the project does not stand in a vacuum and off-site improvements may be necessary to make the project compatible with it’s setting. Staff considers the construction of a shared use path along the entire length of Old Farm Road to be a very important improvement to integrate the proposed development into the adjoining neighborhoods. 9. Staff considers the Board should acknowledge the applicant’s strong opposition to constructing a multi- use path south of the project area path because of a desire to not impact uninvolved adjoiners, but nonetheless recommends the Board require the path be constructed based on City goals and objectives, as described in the LDR, Comprehensive Plan, and recently-completed Kimball Ave / Community Dr / Tilley Drive Network Study. Staff is willing to meet with neighbors between now and final plat to address site-specific design issues. Staff recommends the applicant be directed to includes this recreation path in the final plat submittal. • Plan Sheet C-2 indicates an undetermined type of connection between the Hillside PUD and Eastview PUD. Revise to show as a paved multi-use path as indicated in applicant’s “Hillside Bike and Recreation Connectivity” plan. Multi-use path should be navigable without stairs. • The southernmost segment of Meadow Loop shows a proposed sidewalk. Revise plans to show a 10’ recreation path connecting to Old Farm Road as indicated in the “Hillside Bike and Recreation Connectivity Plan.” #SD-20-40 5 10. Staff recommends the Board to direct the applicant to update Civil Plans to match the “Hillside Bike and Recreation Connectivity” plan as part of final plat submittal. • The plans indicate a sidewalk on the east side of Meadow Loop. Staff recommends this sidewalk be relocated to the west side of Meadow Loop as there are fewer curb cuts on the west side, the need for two mid-block street crossings is eliminated, and the homes on the east side of Meadow Loop are already proposed to be served by a recreation path along Old Farm Road. Staff considers this can be done by swapping the positions of the road and sidewalk without impacting the location of the homes. 11. Staff recommends the Board direct the applicant to relocate the sidewalk to the west side of Meadow Loop as part of their final plat submittal. • The City’s standard for multi-use / recreation paths is 10’ in width. Certain recreation path segments are shown as only 8’ in width. 12. Staff recommends the Board direct the applicant to revise all plans showing 8’ recreation / multi-use paths with a 10’ width, including along Old Farm Road and within lot 32. Applicant may review site- specific exceptions where necessary as part of Final Plan submission. 13. Staff recommends a mid-block sidewalk connection be installed between lots 20-14 and 20-15 to link Meadow Loop and Old Farm Road. This location coincides with a proposed crossing of Old Farm Road in this area. • The mid-block connection between Old Farm Road and Legacy Farm Road at the south of lot 31 is shown on a portion of the plans but appears to be subsumed by a driveway at its western end. 14. Staff recommends the Board direct the applicant to revise plans as part of their final plat submission to show a separated path connection for the entire length of lot 31 between Old Farm Road and Legacy Farm Road, and to request applicant provide their recommendation of surface materials. • The plans do not include a sidewalk on the east side of Hinesburg Road in front of lot 35-1. 15. Staff recommends that the Board require the sidewalk along the south side of Old Farm Road be extended to the southern terminus of Lot 35-1 and to include this in their final plat submission. If/when parcels further to the south are further developed, this sidewalk will be extended. • The plans do not include a sidewalk on the east side of Hinesburg Road between lots 31-1 and 32. 16. Staff recommends that the Board require the applicant to install the sidewalk segment along the east side of Old Farm Road between Historic Barn / Pavilion on lot 32 and lot 31-1 as lot 32 is proposed as an amenity for the entire neighborhood, and to include this in their final plat submission. • Plan sheet C-3 shows a portion of the paved multi-use path outside the Old Farm Road ROW. 17. The Director of Public Works acknowledges that the Board had indicated to the applicant that an easement would be sufficient but requests that the Board reconsider given the small affected area and difficulties this change variable alignment of the rec path would have with winter plowing at night. Staff notes that an alternative option to achieving the Board’s goal of a unique street presence along Old Farm Road could be to install landscaping along the sidewalk to guide plows along the correct alignment. Staff recommends the modifications or landscaping be included in the final plat submission. • The plans indicate that the sidewalk at Legacy Farm Road Extension ends at Mountainview Drive rather than extending to the end of the ROW. 18. Staff recommends the Board require the sidewalk along Legacy Farm Extension be extended to the terminus of the ROW as required by 15.12D as part of the final plat submission. #SD-20-40 6 • The walking loop on Lot 45 does not extend to the southern end of the PUD, limiting the usability of the Open Space lot. 19. Staff recommends the walking loop on Lot 45 connect from the I/C Road to the terminus of Legacy Farm extension at the southern end of the PUD to create a full loop and this be included in the Final Plat submission. 20. Provide a crosswalk across Legacy Farm Road at the pedestrian connection for Lot 45 in the final plat submission. • Throughout the plans, staff recommends that the applicant work with DPW staff to identify locations to including bulb-outs at pedestrian crossings, both to promote a pedestrian-oriented neighborhood and to provide physical and visual cues to drivers to maintain slow speeds. 21. Staff recommends that the applicant work with the Department of Public Works to identify appropriate locations for installation of bulb-outs at pedestrian crosswalks along Old Farm Road and within proposed neighborhood streets and to present these at Final Plat. • Revise plans throughout to ensure that sidewalks and recreation paths are aligned with one another as they cross streets and driveways. • Confirm that on-street parking to complies with ADA design requirements. • Confirm the surface for the pedestrian connection between the Hillside PUD and the north end of Meadow Loop between lots 16-14 and 16-15. • Confirm the surface for the pedestrian connection between the Hillside PUD and across Open Space Lot 19. • Confirm the surface of the pedestrian connections on Open Space lot 45 • The existing pedestrian easement to the City within Business Park North Lot 4 is not shown. Revise plans to show a pedestrian easement in a location that is passable by pedestrians. 22. Staff recommends the applicant provide the requested information/ corrections in the above-bulleted items as part of the final plat submission. Street segments: • Legacy Farm Road Extension terminates at Mountainview Dr in the proposed plans and do not extend to the end of the ROW. 23. Staff recommends the Board direct the applicant to revise the plans to include Legacy Farm Extension extended to end of the ROW as required by 15.12D as part of the final plat submission. Street widths: Street widths along several of the typical cross-sections appear to be excessively wide, including some lanes as wide as 15-20’. Staff recommends these be right-sized to the intended functional use/class of the roadway. 24. The typical cross-section of “I/C Road” shows 15’ Lane withs. Staff recommends the Board direct the applicant to work with Staff and the Bike/Ped Committee to determine whether to narrow the curb-to- curb width or to revised to show bicycle lanes as part of the final plat submission. 25. The typical cross-section of relocated Old Farm Road STA 5+35 – 8+65 shown as 14’. Staff recommends the Board direct the applicant to reduce to not more than 12’ as part of the final plat submission. #SD-20-40 7 26. The typical cross-section of relocated Old Farm Road STA 8+65 – 11+00 shown as 20’, for a total of 40’. Staff recommends the Board direct the applicant to reduce to no more than 3 lanes total as part of the final plat. 27. The typical cross-section of O’Brien Farm Road STA 1+80 – 3+00 is shown as 14’. Staff recommends the Board direct the applicant to reduce to 12’ maximum as part of the final plat. Curb cuts: • The plans show two nearly-adjacent curb cuts to serve lots 40 and 41. 28. Staff recommends the Board direct the application to show a single shared curb cut on the boundary of lots 40 and 41 within the I/C area, replacing the proposed two adjacent curb-cuts, as part of the final plat submission. • The plans show two curb cuts serving Lot 38 within the I/C area. 29. Staff recommends the Board inquire why the applicant finds two curb cuts necessary and to eliminate one if possible as part of the final plat submission. Road construction: 30. Staff recommends the applicant revise its plans to provide 2½” base layer and 1½” inch top layer as part of the final plat submission Roadway Plans for Final Plat 31. Staff recommends that the applicant be required to provide complete roadway plans, including street trees, utilities, lane markings, lighting, signage, etc. as part of their final plat submittal. C1-LR Zoning District As the Board is aware, the applicant is seeking approval for several elements of the C1-LR zoning district, and has therefore prepared a conceptual layout for the C1-LR zoning district to allow the Board to evaluate their request. 14.06B. 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. (3) Without restricting the permissible limits of the applicable zoning district, the height and scale of each building shall be compatible with its site and existing or anticipated adjoining buildings. 14.06C Relationship of Structures and Site to Adjoining Area. (1) The Development Review Board shall encourage the use of a combination of common materials and architectural characteristics (e.g., rhythm, color, texture, form or detailing), landscaping, buffers, screens and visual interruptions to create attractive transitions between buildings of different architectural styles. #SD-20-40 8 (2) Proposed structures shall be related harmoniously to themselves, the terrain and to existing buildings and roads in the vicinity that have a visual relationship to the proposed structures. These criteria are from the site plan review standards section of the LDR. Staff had recommended the Board not provide findings on the C1-LR lots at this stage of review, but the applicant has indicated they wish to have conceptual approval for these lots. Staff recommends any approval of the applicant’s conceptual proposal be preliminary only at this stage, since there are several elements of the proposal which Staff is recommending be adjusted at the final plat stage of review and which may affect the elements that the Board finds acceptable at this stage. The purpose statement of the C1-Limited Retail district is as follows: A. Purpose. A Commercial 1 with Limited Retail C1-LR District is hereby formed in order to encourage the location of general retail at specific intersections in the city, to serve nearby residential areas. These commercial areas are intended to serve the convenience shopping needs of local residents and employees. Their location and design are intended to make them accessible both by motorized vehicle and by foot, thereby somewhat reducing traffic volume in the immediate vicinity. In these areas, businesses offering goods and services will be limited in allowed floor area and use. Such regulations generally follow existing Commercial 1 District regulations. Any uses not expressly permitted are prohibited, except those that are allowed as conditional uses. Design Guide The applicant has provided a “design guide” document, modeled after the Building Envelope Standards tables applicable in the City’s Form Based Code zoning districts, in which they propose certain characteristics which development in the C1-LR zoning district will conform to (with the applicant also requesting authority for the Board to waive several of these at the site plan stage). Staff considers some of these elements to be appropriate, while others are problematic. 32. Staff recommends the Board have the applicant present their full design guide at the hearing and their though process that led to their proposal. Further, staff urges the Board review the proposed design guide in detail as the applicant is seeking broad-level approval for an approach and the Board should feel comfortable with the design guidance required in exchange. In considering all of this, staff recommends the Board consider the purpose of the C1-LR district and notes that the district contains limitations on the size of certain uses (such as retail). Specific elements: • Gateway elements. The proposed design guidance does not highlight or emphasize intersections or gateways. 33. Staff strongly recommends the Board discuss with the applicant how the intersection of Kimball Ave and Kennedy Drive can serve as an attractive gateway to this portion of Kennedy Drive and the C1-LR’s role (as described in the purpose statement) as a destination to serve the needs of area residents & employees, and how similarly the intersection of Kimball Ave / Old Farm Road can serve as gateway to the neighborhood. • The applicant has provided (generally similar) standards for primary and secondary facades, but has not offered a proposal for determining which standards apply. #SD-20-40 9 34. Staff considers primary façade standards should apply on Kennedy Drive, Kimball Ave and Old Farm Road, with secondary façade standards applicable on other roadways, and no façade standards applicable on facades that are separated from a roadway by another development lot. • The applicant has proposed a frontage buildout minimum to match the proposed layout, but has also requested that the first story on the principal facades be allowed to be a garage. Staff considers given the small frontage buildout proposed on most lots, the first story should not be permitted to be a garage. Staff considers a portion of the first story of the buildings may consist of garages as long as the space facing the street is a useable non-garage space. Alternatively, Staff could support a proposal to build out a percentage of each façade, say at least 50%, with non-garage space, after which the façade may consist of garage, or an approach where the first 40’ of depth of the building be non-garage space, such as lobbies, storefonts, or amenities. 35. Staff recommends the Board require the applicant to modify their proposal to prohibit structured parking from fronting on the street. 36. Staff recommends the Board consider a higher minimum frontage buildout or a requirement for civic spaces in between buildings, to create a strong street presence. • The applicant has proposed a “Parking Setback Line” on each lot. 37. Staff considers this to be unnecessarily complex and recommends the Board require the applicant to adhere to standard parking configurations which require the parking to be to the sides or rear of the building. • Staff supports the number and general location of curb cuts, though considers an additional curb cut may be desirable on O’Brien Farm Road East, and recommends the Board provide findings as such. • The applicant is proposing a 20-ft wide landscape buffer on Kennedy Drive and Kimball Ave, which buildings are proposed to be located 0 to 12-ft behind. Buildings are proposed 0 to 12-ft from the property line on all other streets. 38. Staff recommends the Board ask the applicant for more information on this landscaping buffer. Is it proposed to provide screening, simply be lawn, or be an unifying urban feature? Will it contain sidewalk? Will it be used for stormwater treatment? • The proposed 0 to 12-ft setback is very small compared to the standard setback of 30-ft for front yards. 39. Staff considers in order to allow this setback, the Board should require very high quality street presence. • Mix of uses; purpose of C1-LR district 40. Given the preponderance of residential uses among the two O’Brien neighborhoods and nearby areas, staff recommends that the Board discuss with the applicant requiring a minimum amount of retail/service space to serve the adjacent population. • Materials. The applicant has not presented any proposals for façade materials. In the Form-Based Code area upon which this guidance is based, certain exterior finish materials such as vinyl, EIFS, and stucco are prohibited. 41. Staff recommends the Board discuss limitations on exterior finish materials as part of its design guide, consistent with the rest of the Eastview and Hillside PUDs. 42. In addition to those aspects discussed above, Staff calls the Board’s attention to the following related elements [NOTE: these are only a subset of the full design guide, enclosed]. #SD-20-40 10 Applicant Proposed Element Staff Discussion Stories: 5 story maximum, with upper stories permitted to be as little as 30% of the footprint of the first story The C1-LR standard lists a maximum of 2 stories facing the street for single-and two family buildings, and directs the user to the general 35’ height limitation for all other uses. Given the prominence of this location, staff considers that there should be a two story minimum for all street-facing facades, with a maximum of four stories. If the applicant wishes to construct a fifth story, the fifth story should be stepped back at least 20-feet. Staff recommends this be contingent on the Board being satisfied with the full design palate. Glazing: 40% of the width on primary facades and 20% on secondary facades and 6-ft in height with min head height of 7.5-ft for residential, min 7.5-ft for non-residential Five of the eight buildings are proposed as residential. The applicant has proposed a lower minimum glazing for first story garages, but as discussed above, Staff recommends the Board prohibit street-facing first story garages. Entrances: 2 per façade for residential uses; maximum 100’ between entrances for non- residential uses Staff notes that the T4 district upon which is modelled has significantly more stringent requirements (36-48’ max between entrances). In this design guidance, staff recommends a focus on prominence of key entrances at intersections, similar to those within the Urban Design Overlay District along Shelburne and Williston Roads. Parking Maximum: 2 surface spaces maximum for residential units Given the purpose statement for the district – for the C1-LR to serve as walkable destination for nearby residents, staff recommends that Board establish a maximum amount of surface parking in this area, total and encourage use of the land for buildings, civic spaces, and structured parking as needed. Streetscape: benches, café tables and bicycle parking is permitted within the streetscape Staff considers the Board should require a minimum uninterrupted sidewalk width before these elements are permitted. The uninterrupted width should be linear, not meandering. Street trees: 50 ft spacing Street tree minimum spacing is 30-ft where specified. Staff considers there is no reason to allow a larger spacing here. I/C Zoning District These Staff comments were included in the packet for April 20 but time did not allow their review. They have been updated slightly to reflect the Board’s latest feedback. #SD-20-40 11 Roadway Connection to Tilley Drive PUD and Recreational Loop: The applicant has modified their plans to provide a feasible connection to the Tilley Drive PUD. They have also reached an agreement with the Tilly Drive PUD that they would construct a pedestrian path along the future roadway alignment in the Tilley Drive PUD until such time as the Tilley Drive PUD connects the roadway. Staff is generally supportive of the revised configuration, but considers that the previously proposed recreation path is less functional as currently designed. A comparison of the previous (left) proposal and current (right) proposal is below. The previous proposal provided a large looping off-road trail network. 43. As noted above, staff recommends that the Board require the walking trail within the updated configuration of Lot 45 to loop back from the Recreation path to Legacy Farm Road extension at the southern boundary of the PUD. This would make for a more complete walking loop for residents and employees. Vehicular connection between R1 and I/C zone: The applicant previously provided a 50-ft easement centered on the proposed recreation path, which they are no longer showing. Given the reconfigured I/C road and the proposed ROW easement off the south end of Legacy Farm Extension, Staff considers the likelihood of a future connection to be even more viable, If the construction of a roadway would indeed require a significant embankment as the applicant testified, a 50-ft roadway does not accommodate the required side slopes. Such a change will require a modest realignment of the homes on Legacy Farm Ave. 44. Staff recommends the Board require the applicant to design for an retain a 60-ft ROW for future connection between Legacy Farm Ave and the I/C road. OPEN SPACES 15.18A(6) Open space areas on the site have been located in such a way as to maximize opportunities for creating contiguous open spaces between adjoining parcels and/or stream buffer areas. For Transect Zone subdivisions, this standard shall apply only to the location of natural resources identified in Article XII of these Regulations and proposed open spaces to be dedicated to the City of South Burlington. The applicant has agreed to work with City Staff to develop a proposal for ownership of open space prior to final plat. The applicant has significantly modified the resident club from their initial proposal. Staff considers it to be an attractive feature. Staff notes that it does not appear the homes on Lot 32 have a relationship to the path along the outside of the club area. 45. As previously noted, Staff recommends the Board discourage a heavy buffer in this area, and instead encourage the homes on Lot 33 to use Lot 32 as their neighborhood play area. Regarding parking at Resident Club, 14.06B(2)(b) is as follows. #SD-20-40 12 The development review Board may approve parking between a public street and one or more buildings if the Board finds that one or more or of the following criteria are met. The Board shall approve only the minimum necessary to overcome the conditions below. (v) The principal use of the lot is for public recreation 46. Staff recommends the Board ask the applicant to discuss their revised proposal as it pertains to this exception. If there is no portion of the Resident Club which is principally for public recreation, the proposed parking may not be approved. MODIFICATION OF STANDARDS 14.07E allows the Board to modify standards as long as the general objectives of Article 14 and the Comprehensive Plan are met. The applicant’s waiver requests were discussed at various hearings. Staff and the applicant feel there was some confusion about the requests. Waiver requests which Staff considers warrant further discussion are as follows. Waiver Request 1 – 10: The applicant had requested a variable set of waivers for residential setbacks. The Board directed the applicant to prepare a simplified waiver request for the lots currently proposed for development. This has not yet been done. 47. Staff considers this can be done at final plat, and recommends the Board draft findings on these requested waivers accordingly. Waiver request 13 – 14: The applicant is requesting waiver of screening on commercial lots where the commercial lots abut residential lots. The applicant clarified that the intent of this request is that they intend to provide screening, but would prefer to be allowed to provide it on either the residential lots or commercial lots. 48. Staff recommends the Board accept this request and modify their findings to reflect the clarified request. Waiver request 15: The applicant is requesting that minimum required landscaping be allowed to be provided anywhere within the master plan. As previously discussed, since no actual master plan is proposed, Staff considers the Board cannot grant this waiver. It was previously recommended that the Board allow landscaping to be placed anywhere within the lots proposed for development (including the recreation loop and park lots) as part of this application, but not outside these lots, and further that landscaping required in the future be applied on the lots proposed for development at the time it is required. Upon discussion with the applicant, Staff wishes to clarify that generally, required minimum landscaping budget can be used anywhere within the PUD, but that the landscaping standards still require sites to be well landscaped. In other words, just because the Board may permit landscaping required for construction of a building to be installed in a park, they are not required to if such an approval would result in the building site being poorly landscaped. Staff considers no waiver is required. Waiver Request 21: “Applicant requests a finding that parking may be permitted with only site plan and conditional use review in the context of site plan review for a building on any approved lot in the PUD.” Because this request didn’t make sense to Staff, Staff discussed this request with the applicant. The applicant explained they are asking to be allowed to permit shared parking on an adjacent lot when no other development is proposed on that lot. Staff considers if the project is reviewed as a PUD, this can be done using the Board’s waiver ability, though the Board will have to decide what restrictions will be imposed. #SD-20-40 13 49. Staff recommends standard limitations, such as parking to the sides and rear of existing or proposed buildings, be imposed. Staff also considers that additional screening of parking which is not reasonably proximate to a building should be required. Waiver request 25: the applicant requests waiver of the requirement that construction in the IC zoning district be exempt from the requirements to have common elements with the remainder of the PUD. This request was discussed briefly on February 17. The specific standards are as follows. 14.06B. 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. (3) Without restricting the permissible limits of the applicable zoning district, the height and scale of each building shall be compatible with its site and existing or anticipated adjoining buildings. 14.06C Relationship of Structures and Site to Adjoining Area. (1) The Development Review Board shall encourage the use of a combination of common materials and architectural characteristics (e.g., rhythm, color, texture, form or detailing), landscaping, buffers, screens and visual interruptions to create attractive transitions between buildings of different architectural styles. (2) Proposed structures shall be related harmoniously to themselves, the terrain and to existing buildings and roads in the vicinity that have a visual relationship to the proposed structures. 50. Staff considers there are a number of ways to meet these criteria. The presence of an intervening open space and roadway reduces the needed reliance on architectural similarity. Staff continues to recommend the Board deny this request. Recommendation Staff recommends the Board attempt to take all necessary testimony before concluding for the evening, and continue the hearing for the purpose of allowing Board to deliberate and to review a draft decision. Staff considers that unless major unresolved issues are identified during deliberations, this continuation need not extend the timeline to a decision when compared to closing the hearing.

Eastview - O’Brien Home Farm Traffic Impact Assessment March 30, 2021 Executive Summary The following summarizes the results of the revised traffic impact assessment (TIA) for the second phase of the O’Brien Home Farm mixed use development project (hereafter referred to as “Eastview” or “the Project”). Eastview proposes to develop lands of O’Brien Brothers located along Kimball Avenue, Old Farm Road and Kennedy Drive in South Burlington. The exact eventual development of the full site is currently unknown. In reviewing the land and zoning in place, a potential development scenario has been developed in order to evaluate the potential traffic impacts as the Project develops. This development scenario, broken down into smaller parts with corresponding peak hour trips, will be the benchmark against which future development proposals are evaluated. This TIA uses the following development as represent the potential “Full-Build” development scenario: ! 126 residential units in single-family residences and duplexes (R1 Area), ! 289 mid-rise multi-family units (C1-LR Area), ! 120 attached congregate care units (C1-LR Area), ! a 120 room hotel (C1-LR Area), ! 14,000 sf of retail space (C1-LR Area), ! 97,000 sf of medical-dental office and commercial space (C1-LR Area) and, ! 309,000 sf of medical-dental office and commercial space (I-C Area). The initial construction phases will be to construct the residential units in the R1 and C1-LR Areas. Subsequent construction phases of the proposed commercial uses will be market driven. Because this Project will most likely be developed over an extended time period, this TIA examines future traffic conditions over a 10-year period commencing in 2022 instead of the traditional 5-year period. This revised TIA also recognizes the recently completed VT 116/Kimball Avenue/Tilley Drive Area Land Use & Transportation Plan.1 Key transportation planning concepts emerging from that study for this geographic area include: C Constructing several new connector streets and I-89 Exit 12B to provide alternate travel routes diverting traffic from existing streets. C Reducing future vehicular traffic levels by a) constructing bicycle and pedestrian infrastructure improvements to encourage increased multi-modal trips, and b) implementing transit enhancements. C Constructing moderate intersection upgrades only where absolutely necessary (i.e., permitting reduced levels of service). The study area of this TIA extends from Hinesburg Road on the west to Gregory Drive on the east, and from Williston Road south to Kimball Avenue, Kennedy Drive and Old Farm Road. Capacity analyses determined that each major intersection in this study area will experience acceptable levels of service upon completion of the proposed development in the R1 and C1-LR Areas plus one-half of the proposed development in the I-C Area. 1 VT 116/Kimball Avenue/Tilley Drive Area Land Use & Transportation Plan Final Report, VHB, November 2020. Lamoureux & Dickinson ii Consulting Engineers, Inc. Acceptable levels of service will also be maintained with further development in the I-C area beyond the 50% build-out threshold at all but two intersections. The first is Kennedy Drive/Kimball Ave/Bayberry Ln. This intersection will be approaching capacity with full build of the I-C Lots. Although the overall intersection level of service will remain at LOS D, individual approaches will begin to experience LOS E/F with the predicted year 2032 full build peak hour traffic volumes. It appears that future construction of the Tilley Drive connections will not materially affect the foregoing. The second intersection is Hinesburg Rd/Old Farm Rd. With future levels of service for traffic exiting Old Farm Rd predicted to drop to LOS F with full build of Eastview, a short-term solution would be to widen the Old Farm Rd approach to provide a short right-turn slip lane. A better long-term solution, however, will be to divert traffic off from Old Farm Rd by constructing one or more of the Tilley Drive connections. The following transportation improvements are included in the Eastview development: C In conjunction with Hillside (presently under construction), Eastview will construct an extensive network of new interconnected sidewalks and shared-use paths linking with the City’s existing sidewalk and shared use path network along Kimball Ave, Kennedy Drive, Eldredge St and Hinesburg Rd. C Implementing traffic calming measures on Old Farm Road to slow traffic traveling through the residential area and to safely accommodate bicycle and pedestrian traffic. C Relocating the Kimball Ave/Old Farm Rd intersection to line up directly across the existing office complex at #20-30 Kimball Ave. This will increase the distance between Kennedy Drive and Old Farm Rd from 200’ to 560’. C The I-C Lots access road will form the northerly half of one of the future Tilley Drive connections. The southerly half of that connection will be located on and constructed by the adjacent Mountain View Office Park. Eastview also proposes to construct the following roadway and intersection improvements as development progresses towards completion (full build): Kennedy Dr / Kimball Ave intersection C Modify the signal phasing to provide split phasing for the Kimball Ave and Bayberry Lane approaches after completing residential development in the R1 and C1-LR Areas and/or upon commencing commercial development in the C1-LR Area. Kimball Ave / Old Farm Rd intersection C Relocate the intersection after completing residential development in the R1 and C1-LR Areas and/or upon commencing commercial development in the C1-LR Area. C Restripe the pavement markings on Kimball Ave to provide left-turn lanes in both directions at the relocated intersection. C Install a new traffic signal when warranted. Kimball Ave / I-C Lots Access Rd intersection C Construct this intersection upon commencement of commercial development in the I-C Area. C Restripe the pavement markings on Kimball Ave to provide left-turn lanes on both directions at the new intersection. C Install a new traffic signal when warranted. C Add an exclusive right-turn lane exiting the I-C Lots Access Road once the Tilley Dr connection is completed or development of the I-C lots exceeds the proposed 50% Build threshold. Conceptual sketches illustrating the above recommended improvements on Kimball Ave are attached to the TIA. Lamoureux & Dickinson iii Consulting Engineers, Inc. Based on this Project’s estimated pm peak hour trip generation and directional patterns, it will also pay almost $3,000,000 in state and local transportation impact fees to mitigate its projected traffic impacts at other nearby off-site intersections and almost $700,000 in local recreation impact fees. A large majority of the latter will be used to construct off-site sidewalk and shared use path improvements throughout the City of South Burlington. The TIA concludes that with the above improvements and impact fees, the existing street network in the immediate vicinity will have sufficient capacity and safety to accommodate the additional traffic generated by the Project. Lamoureux & Dickinson Page 1 Consulting Engineers, Inc. Eastview - O’Brien Home Farm Traffic Impact Assessment June 16, 2020 rev. March 30, 2021 1.0 Introduction This traffic impact assessment (TIA) examines the potential traffic congestion and safety impacts of the second phase of the O’Brien Home Farm development, hereafter referred to as Eastview or the Project. The O’Brien Home Farm originally included lands east of Kennedy Drive and Hinesburg Road, along both sides of Old Farm Road, and along both sides of Kimball Avenue. Large portions of the farm have been developed over the years. Most recent is the Hillside at O’Brien Farm2 development presently under construction between Hinesburg Road, Kennedy Drive and Old Farm Road. Eastview includes lands located on both sides of Old Farm Rd, fronting on Kennedy Drive and Kimball Avenue. Specifically, the land involved contains three distinct zoning districts, the Residential 1 PRD zoning district (“R1”), the Commercial 1 - Limited Retail zoning district (“C1-LR”) and the Industrial-Commercial zoning district (“I-C”). Each district allows for specific uses. City of South Burlington’s Land Development Regulations (LDR) require uses to be located on the land that is zoned accordingly; preventing mixing of certain uses across zoning lines. Given this, the potential uses in distinct areas of the Project will be identified herein by the zoning district in which those uses are located. The following mix of residential and commercial development is permissible in the R1 and C1-LR Areas of the Project: C 126 residential units in single-family residences, duplexes and triplexes (R1),3 C 289 mid-rise multi-family units (C1-LR), C 120 attached congregate care units (C1-LR), C a 120 room hotel (C1-LR), C 14,000 sf of retail space (C1-LR), and C 97,000 sf medical-dental office and commercial space (C1-LR). The above development will be accessed by several new side streets located on both sides of Old Farm Rd and also linking with the adjacent Phase One development. The northerly portion of Old Farm Road will be relocated; moving the intersection of Kimball Ave and Old Farm Rd ±360 ft east to be directly opposite the existing driveway access serving the office complex at 20-30 Kimball Ave and 275 Kennedy Dr. Eastview also includes several new industrial/commercial lots located further east on Kimball Ave in the I-C zoning district. While a range of uses are possible, this TIA is based on 309,000 sf of medical-dental office and commercial space to be distributed among the new I-C lots. This sizing is based on a schematic analysis of possible building and parking layouts, and represents an estimate of this area’s future build-out potential. The I-C Lots will be served by a separate new street accessing directly onto Kimball Ave. The I-C Lots street will also form part of one of the Tilley Drive connections shown the City of South Burlington’s Official Map. The location of the Project and the intersections which will be examined in this TIA are shown in Figure 1. 2 Previously referred to as Phase One. 3 All of which will be treated herein as single-family units for trip generation purposes. Lamoureux & Dickinson Page 2 Consulting Engineers, Inc. Figure 1 - Project Location and Study Intersections More specifically, this TIA will: C Project present and future background design hour traffic volumes and traffic congestion conditions at major intersections near the Project. C Determine the future vehicular trip generation and peak hour directional patterns of the proposed land- uses. C Evaluate whether the proposed development will create unreasonable traffic congestion conditions. C Examine traffic safety conditions. C Identify the scope of traffic improvements required to mitigate the effects of the proposed development. For the purpose of this TIA, it is anticipated that construction of this Project will begin in 2022, and will require 5-10 years to complete. This TIA therefore examines future traffic conditions for the years 2022 and 2032. 2.0 Background Traffic Volumes For this study, background traffic volumes were obtained from recent traffic counts performed by the Vermont Agency of Transportation (VTrans). The study area of this TIA extends from Hinesburg Rd east to Industrial Avenue, and from Williston Rd south to Kennedy Dr and Old Farm Rd. The existing and proposed intersections which will be examined in this TIA are shown in Figure 1. Weekday turning movement count data is available at all but one of the existing intersections; Williston Rd/Gregory Dr. Unfortunately, as work on this TIA was beginning, the COVID-19 pandemic struck, and the resulting sharp decline in traffic volumes has prevented our being able to perform new weekday am and pm peak period turning movement counts at this intersection. Future traffic conditions at this location will be addressed in a supplement to this TIA when normal traffic patterns resume. Three new intersections are associated with this Project. The first, Kennedy Dr/Two Brothers Dr, will be constructed as part of the Hillside at O’Brien Farm Phase One development. Future peak hour turning movement volumes for this intersection were obtained from the TIA performed by this office for that Lamoureux & Dickinson Page 3 Consulting Engineers, Inc. development. The second proposed intersection is Kimball Ave/Old Farm Rd. The northerly portion of Old Farm Rd is proposed to be relocated as part of this Project; moving this intersection approximately 360 ft to the east to line up opposite the access to the office complex on the north side of Kimball Ave. The third new intersection will be located on Kimball Ave at the new street serving the I-C Lots. Existing traffic count data indicates that the adjacent street network in the immediate vicinity of this Project experiences its highest traffic volumes during the afternoon peak hour period. Hourly traffic data from nearby VTrans continuous count stations (CTC) located in South Burlington and Williston reinforce this. Thus, the pm peak hour is the time period during which the design hour volume (DHV) generally occurs. The DHV is the 30th highest hourly traffic volume that occurs in a given year, and is used in the design of highways and intersections to determine existing and future traffic congestion conditions. To adjust the observed peak hour volumes to a design hour (DHV) condition, daily adjustment factors corresponding to the dates of the turning movement counts were calculated from nearby CTC’s. Additional adjustments were also made to account for future background traffic growth from the year of each turning movement count to the years 2022 and 2032. From VTrans data4, traffic growth in Vermont’s urban areas during the 2015 - 2019 period was flat (zero growth). From 2019 to 2022 and from 2022 to 2032, VTrans projects 2% and 5% traffic growth rates, respectively. Detailed design hour volume calculations, together with figures showing the resulting estimated 2022 and 2032 background peak hour volumes for each intersection, are enclosed in Appendix A. Note: Appendices are enclosed under separate cover. 3.0 Other Approved Development Peak Hour Trips To the above ‘No-Build’ pm peak hour volumes must also be added trips generated by other nearby major developments that have received their state and local permits, but have not yet been constructed. The first “Other Development” is the Hillside at O’Brien Farm Phase One development. Although this development is presently under construction and some homes have been completed, it is treated in this TIA as an unbuilt development. Estimated morning and afternoon peak hour trips for Hillside at O’Brien Farm Phase One were obtained from the TIA for that project.5 The second “Other Development” is the proposed FedEx Ground Distribution Center to be located on Community Drive at Technology Park. Estimated morning and afternoon peak hour trips were also obtained from the TIA for that project.6 The total peak hour trips from the above two developments, together with figures showing the sum of the 2022 and 2032 background peak hour volumes and other approved development trips, are illustrated in the figures contained in Appendices E and F. This is also known as the “No-Build” development scenario (see pg. 7). 4 Continuous Traffic Counter Report Based on 2018 Traffic Data, Vermont Agency of Transportation, February 2019 and unpublished 2019 traffic data. 5 O’Brien Home Farm PUD - Phase 1 Traffic Impact Assessment, Lamoureux & Dickinson, August 8, 2016 6 Proposed FedEx Ground Distribution Center Traffic Impact Study, VHB, September 4, 2019 Lamoureux & Dickinson Page 4 Consulting Engineers, Inc. 4.0 Project-Generated Peak Hour Trips Eastview’s peak hour trip generation was estimated using published trip generation rates7 for the proposed residential land-uses. In the case of the proposed commercial land-uses, the estimated peak hour trips are intended to include a broad range of potential businesses. It is proposed that medical-dental offices will comprise a large portion of the commercial development. Should actual land-uses and their sizes differ substantially from the above, careful attention will be needed to track the resulting peak hour trip generation relative to the estimated trips outlined below. The ITE has also developed a methodology for estimating the internal capture of pm peak hour trips between the residential, office space, restaurant and retail components of mixed-use developments.8 While Eastview includes connections with the Hillside at O’Brien Farm development which will logically expand the internal trip capture between them, for the purpose of this study, the internal capture calculations have been limited to just this Project. Additionally, internal trip capture for the I-C Area has been calculated separately from the R1 and C1-LR Areas. The same methodology also incorporates modal-split calculations to account for non- vehicular travel. For the purpose of this TIA, however, all trips were estimated to be vehicle trips without any credit for transit or bicycle/pedestrian trips. Some commercial land-uses also typically attract “pass-by” trips in addition to creating new “primary” trips. Pass-by trips are generated by motorists who are already driving by the site on the adjacent roadways; in this case Kennedy Drive or Kimball Ave. Instead of simply driving by, they enter the Project, and then exit in the same direction that they were originally traveling. For the purpose of this TIA, potential pass-by trips were not estimated. As specific commercial uses are identified, however, they may become significant in reducing future off-site traffic impacts. In addition to the above, both Hillside and Eastview have been designed to support alternate travel modes (transit, walking & biking) through the use of extensive sidewalks, bike paths and their proximity to existing local bus routes. Mixed-uses have also been incorporated into the two developments, further encouraging alternate travel modes. Under VTrans’ Travel Demand Management Guidelines, these physical attributes qualify Eastview to a 6% reduction in its peak hour trip generation. The resulting peak hour vehicular trip generation are summarized in Tables 1 and 2. Detailed calculations are enclosed in Appendix B. The directional distributions of weekday peak hour project trips were estimated based on U.S. Census residence to work travel patterns for the City of South Burlington. This data is available in two formats; the workplace destinations of South Burlington residents, and the origins of people traveling to work in South Burlington. Since residential trip patterns are primarily determined by the geographic distribution of employment opportunities9, the workplace destinations of South Burlington residents can be applied to estimate the directional patterns of those trips. Conversely, commercial trip patterns are primarily determined by the geographic distribution of population within an anticipated sphere of influence. Thus, the commercial trip patterns were based on the origins of people traveling to work in South Burlington. The foregoing directional patterns will also be influenced by future street connections linking Kimball Ave and Community Drive with Tilley Drive. Those connections will provide shorter and more favorable alternate routes for traffic presently using Kimball Ave, Kennedy Drive, Old Farm Rd, Hinesburg Rd and their intersections. Future traffic generated by the I-C Lots will also be able to use that Tilley Dr connection as an alternate route to travel to/from points south of the site. Overall, we estimate that these future connections 7 Trip Generation, Institute of Transportation Engineers, 10th Edition 8 Trip Generation Handbook, Institute of Transportation Engineers, 3rd Edition 9 Traffic Impact Analysis, American Planning Association, 1984 Lamoureux & Dickinson Page 5 Consulting Engineers, Inc. will divert 288 vph and 254 vph during the 2032 am and pm peak hour periods, respectively, with full-buildout of Eastview.

Lamoureux & Dickinson Page 6 Consulting Engineers, Inc. 5.0 Traffic Congestion Levels of service (LOS) at intersections are determined by the average control delay; measured in seconds per vehicle. The methodology for analyzing LOS is established by the Highway Capacity Manual (HCM)10. The analyses were performed using Synchro 10. Table 3 summarizes the LOS and delay criteria for signalized intersections. Table 3 - Intersection Level of Service Criteria LOS Avg. Delay (sec/veh) Quality of Service Stop Controlled Signal Controlled A B C D E F ≤10 ≤15 ≤25 ≤35 ≤50 >50 ≤10 ≤20 ≤35 ≤55 ≤80 >80 Free flow with little or no queuing Low delays with short queues Moderate delays and queues with occasional cycle failures* Moderate delays and queues with noticeable cycle failures Long delays and queues with frequent cycle failures Very long delays and queues with continued cycle failures * A cycle failure occurs when a vehicle has to wait more than one signal cycle to pass through the intersection. The City of South Burlington’s Land Development Regulations (LDR’s) identify LOS D as the minimum standard for the overall level of service at signalized intersections. The LDR’s also identify LOS D as the minimum standard for each through movement on the major street. VTrans’ Level of Service Policy11 for the state highway system identifies LOS C as the desired design standard, except that reduced LOS may be acceptable on a case-by-case basis, particularly within densely settled areas where the geometric improvements required to achieve LOS C would create negative cultural and environmental impacts. In cases where the existing LOS is less than desired and where the necessary geometric improvements are not feasible, the policy states that a lower LOS may be acceptable, provided that a development’s impact can be effectively mitigated by implementing other congestion management strategies. VTrans’ LOS Policy has been generally interpreted in built-up areas to permit LOS D as an acceptable overall intersection rating for signalized intersections. Also, that individual lane groups or approaches may experience LOS E. However, should an individual lane group or approach experience LOS F or a volume/capacity ratio greater than 1.0, the intersection is considered to have failed. In cases where an intersection fails under projected no-build and/or build conditions, mitigation may be required, if reasonably possible, in order to mitigate a development’s traffic impacts and not exacerbate the no-build conditions. LOS standards for unsignalized intersections are different than for signalized intersections. The City’s LDR’s do not specifically establish a LOS standard for stop-controlled intersections. On the other hand, VTrans’ LOS Policy identifies LOS D as the minimum design standard for traffic exiting a stop-controlled approach when traffic volumes on that approach equal or exceed 100 vph for a one-lane approach, or 150 vph for a two-lane approach. VTrans does not set a LOS standard for stop-controlled intersections not meeting those approach volume thresholds. 10 Highway Capacity Manual, Transportation Research Board, 6th Edition 11 Highway Design “Level of Service” Policy, Vermont Agency of Transportation, May 31, 2007 Lamoureux & Dickinson Page 7 Consulting Engineers, Inc. The recently completed VT 116/Kimball Avenue/Tilley Drive Area Land Use & Transportation Plan12 prepared for the City of South Burlington and the Chittenden County Regional Planning Commission proposes to mitigate future traffic congestion conditions associated with this and other nearby developments in part by permitting reduced levels of service and constructing moderate intersection upgrades. Instead of large-scale roadway and intersection improvements, that study recommends: C Constructing several new connector streets and I-89 Exit 12B to provide alternate travel routes to divert traffic from existing streets. C Reducing future vehicular traffic levels by a) constructing bicycle and pedestrian infrastructure improvements to encourage increased multi-modal trips, and b) implementing transit enhancements. This Project’s impact on future levels of service and average delays was analyzed by performing intersection capacity analyses for four analysis scenarios: C No-Build. This analysis scenario includes background traffic growth and other development-generated traffic as described above, but no Project-generated trips. C Residential-Build. This analysis scenario adds all of the residential development trips from Eastview’s R1 and C1-LR Areas to the No-Build traffic volumes (264 pm peak hour trips). C Partial-Build. This analysis scenario adds all of Eastview’s residential development trips from the R1 and C1-LR Areas plus the projected full-build commercial development trips from the C1-LR Area and 50% of the full-build commercial development trips from the I-C Area (1,255 pm peak hour trips) to the No-Build traffic volumes. C Full-Build. This analysis scenario adds all of Eastview’s residential development trips from the R1 and C1-LR Areas plus the projected full-build commercial development trips from the C1-LR and I-C Areas (1,776 pm peak hour trips) to the No-Build traffic volumes. Figures illustrating the resulting morning and afternoon peak hour analysis scenario volumes without the future Tilley Drive connections are enclosed in Appendices E-1 and E-2, respectively. Figures illustrating the resulting morning and afternoon peak hour analysis scenario volumes with the future Tilley Drive connections are enclosed in Appendices F-1 and F-2, respectively. The Residential-Build analysis scenario was analyzed at all intersections during the 2022 design year, but not during the 2032 design year, as it is expected by then to have been superseded by the 2032 Partial-Build analysis scenario (except potentially at the Kimball Ave/Old Farm Rd intersection; see below). The Partial- Build and Full-Build analysis scenarios were analyzed only during the 2032 design year, as development of proposed office and commercial uses are not expected to commence until after 2022. The above analysis scenarios are further expanded by the addition of future connections to Tilley Drive. Thus, the Partial-Build and Full-Build analysis scenarios were also analyzed for existing conditions without those connections and for future conditions with those connections. The traffic congestion impacts of the Project can be identified by comparing the results for each analysis scenario. The results are presented for each intersection below. Detailed intersection capacity analyses worksheets are grouped by intersection and enclosed in Appendices G - P. Williston Road/Hinesburg Road/Patchen Road Table 4 presents the results of the intersection capacity analyses at this intersection. The results indicate that LOS C will be maintained for all analysis scenarios.

Williston Road/Industrial Avenue Table 6 presents the results of the intersection capacity analyses at this intersection.

The results indicate that the existing overall intersection levels of service are LOS C during both the AM and PM peak hour periods. By 2032, however, future levels of service will drop to LOS D. Maintaining LOS D as Eastview development progresses will require that the existing traffic signal phasing be modified to split the green phase that presently serves the Kimball Ave and Bayberry Ln approaches simultaneously. In addition to the above, the results of the intersection capacity analyses indicate that combined westbound through/right lane on Kimball Ave and/or the northbound through lanes on Kennedy Dr will begin to experience LOS F and oversaturated traffic congestion conditions (v/c ratio ≥ 1.0) under predicted 2032 Full- Build conditions. Although mitigated somewhat by the future Tilley Drive connections, these results indicate that future traffic congestion conditions at this intersection should be periodically reexamined after Eastview’s Partial-Build peak hour trip generation is reached.

Kimball Avenue/Old Farm Road Note: It is proposed to relocate the Kimball Ave/Old Farm Rd intersection as Eastview development progresses. The new intersection will be located to line up directly across the existing driveway to the 20-30 Kimball Ave office complex; creating a new four-way intersection. The analyses shown in Table 11 are for a three-way intersection. Unfortunately, no turning movement data is available for traffic entering and exiting the existing office complex, and the current COVID-19 pandemic has prevented our being able to obtain a representative traffic count. Future traffic conditions associated with a four-way intersection at the new location will be addressed in a supplement to this TIA when normal traffic patterns resume. This intersection is presently located ±200’ east of Kennedy Drive and is stop-sign controlled (unsignalized). Relocating it will increase the separation from Kennedy Drive to ±560’. A new traffic signal will also be installed and the pavement markings on Kimball Ave restriped to create a left-turn lane for traffic turning onto Old Farm Rd. These improvements are illustrated in Figure 2. Table 11 presents the results of the intersection capacity analyses at this intersection. The results indicate that the existing intersection has adequate capacity to remain in its current location and with stop-sign control with the proposed initial residential only development in the R1 area. The results also indicate that LOS C will be maintained as development of the Project progresses further, the intersection is relocated and the improvements described above made.

It will require, as development of the I-C Lots progresses, installing a traffic signal and restriping the pavement markings on Kimball Ave to provide an exclusive left-turn lane for traffic entering the I-C Lots. These improvements are also illustrated in Figure 2. The Partial-Build analysis scenarios are based on a single shared left- and right-turn lane exiting the I-C Lots Access Rd. Capacity analyses of the Full-Build analysis scenarios identified that an additional improvement in the form of an exclusive right-turn lane for traffic exiting the I-C Lots Access Rd will be needed to maintain desired levels of service. Lamoureux & Dickinson Page 12 Consulting Engineers, Inc. This intersection and the I-C Lots access road will form the northerly half of one of the future Tilley Drive connections. The southerly half of that connection will be located on and constructed by the adjacent Mountain View Office Park. The analyses results shown in Table 12 are based on this intersection being signalized once I-C area development reaches 50% of its projected build-out (the Partial-Build analysis scenario).

Future levels of service will drop to LOS E as development of Eastview progresses, ultimately dropping to LOS F in the 2032 PM Full-Build analysis scenario. The solution to that, as can be seen in the bottom rows of Table 14, is the construction of the Tilley Drive connections. 6.0 Traffic Safety Vehicular traffic safety is influenced by many factors, including road width, pavement conditions, sight distances, lighting, proper signing and pavement markings, speed limits, alignment, number and spacing of accesses, etc. The following discusses several of the more important factors with respect to conditions on the adjacent street network in the immediate vicinity of the Project. Speed limits on the major streets adjacent to the Project are typical of urban streets; i.e., 30-40 mph. The speed limit on Old Farm Rd is 25 mph. The new development streets are also proposed to have 25 mph speed limits. Safe traffic conditions on the new development streets will be provided by designing those roads and their intersections in accordance with accepted standards, and by providing adequate sight distances, street lighting, pavement markings and traffic signs. The Project also proposes to add new traffic-calming features on Old Farm Rd in order to slow vehicular traffic and provide a safer environment for pedestrians. Crash History Intersections and roadway segments which experience a statistically significant above average crash rate are identified as high crash locations. VTrans has traditionally updated its High Crash Location Report13 every two years based on the most recent five-year crash history. The most recent report, however, is for the 2012-2016 five-year period. The Identified high crash locations within the study area of this TIA are shown in Table 16. 13 High Crash Location Report: Sections and Intersections 2012-2016, Vermont Agency of Transportation, August 2017 Lamoureux & Dickinson Page 14 Consulting Engineers, Inc. Of the 75 crashes that occurred at the Williston Rd/Hinesburg Rd/Patchen Rd intersection, 70 were property damage only crashes. The remaining 5 crashes resulted in 9 injuries. The Williston Rd (mm 1.658 - 1.958) segment begins just west of the Airport Rd intersection and continues east through the Kennedy Dr/Airport Dr intersection. Of the 75 crashes that occurred on this 0.3 mile long segment of Williston Rd, 63 were property damage only crashes. The remaining 12 crashes resulted in 14 injuries. It is pertinent to note that the Williston Rd/Kennedy Dr/Airport Dr intersection was not identified as a high crash location. With 36 of the 75 crashes in this segment occurring at the intersection, its presence is the primary reason for the segment being identified as a high crash location. Table 16 - High Crash Locations Location # Crashes Actual Crash Rate Actual/Critical Ratio Intersection Williston Rd/Hinesburg Rd/Patchen Rd Segment Williston Rd (mm 1.658 - 1.958) 75 75 1.373a 8.461b 1.808 1.298 a crashes per million vehicles b crashes per million vehicle miles Table 17 provides a breakdown of the crash types at the above locations. It shows that just over one-half of the crashes in the above high crash locations are rear-end crashes. Signalized intersections typically do experience greater numbers of rear-end crashes, which are generally minor and do not result in severe injuries; unlike opposing direction collisions which traffic signals are intended to prevent.

Every street in the Hillside and Eastview developments will have a sidewalk and/or a shared-use path on one or both sides. Marked crosswalks and pedestrian signals will also be provided at each new signalized intersection on Kimball Ave (i.e., at Old Farm Rd and at the I-C Lots Access Road). Eastview’s new shared-use bicycle paths will also fill in existing gaps along Kimball Ave; providing improved connectivity for existing bicyclists and pedestrians. Notably, Eastview’s proposed sidewalk and shared-use path network includes several off-road facilities directly linking Hillside, Eastview along Old Farm Rd and the new I-C Lots Area. One of the functions of these links will be to provide more direct travel routes from the Eastview development to the existing bus stops on Kennedy Dr. Figure 3 highlights the proposed off-road ped/bike facilities together with the locations of the existing bus stops. Also shown is the new Kennedy Dr/Two Brothers Dr signalized intersection which will be constructed as part of the Hillside development. This intersection will provide new crosswalks and pedestrian signals enabling bicyclists and pedestrians from Hillside and Eastview to reach the existing shared-use path located on the north side of Kennedy Dr. This office also previously prepared a concept plan14 showing traffic calming measures and crosswalks along Old Farm Rd. That plan has since been superseded by a preliminary plan15, included herein as Figure 4, illustrating existing and proposed shared-use paths serving the Hillside and Eastview developments together with proposed pedestrian and bicycle facilities and traffic calming measures on Old Farm Rd. The above proposed pedestrian and bicycle facilities will encourage non-vehicular travel not only among the various Hillside and Eastview neighborhoods, but to and from neighboring areas and other off-site destinations (i.e., schools and other community facilities). They will also provide convenient access to local transit service on Kennedy Drive. Local and regional transit service linking South Burlington with surrounding communities is provided by Green Mountain Transit (GMT). Green Mountain Transit offers several routes serving the Kennedy Dr/Kimball Ave area. The first is the Red Line which travels Williston Rd to/from destinations in Burlington and Williston. The closest Red Line bus stops are on Williston Rd near its intersection with Kennedy Dr. Service on this route is presently provided on 20-minute peak period headways. The second GMT local transit route is the Purple Line. The Purple line originates and terminates in downtown Burlington with intermediate stops at the UVM Medical Center and the University Mall. From the UVM Medical Center, it travels to Dorset St and then to Kennedy Dr. The route circulates in counter-clockwise fashion along Kennedy Dr east of Hinesburg Rd, thence to Airport Dr, White St and Hinesburg Rd back to Kennedy Dr where it continues west on Kennedy Dr back to Dorset St. From Dorset St, it retraces its route back to downtown Burlington. The closest bus stops along this route on Kennedy Dr are located at Windridge and in front of the Community Bank just north of Kimball Ave. Service on this route is presently provided on 45-minute peak period headways. The Special Services Transportation Agency (SSTA) also operates the “Tilley Drive Shuttle” serving the medical office buildings on Tilley Drive and the Sphinx Building located just south on Hinesburg Rd. Advance reservations are required to use this shuttle, which originates and terminates at the University Mall. Although it travels Hinesburg Rd south of Kennedy Dr in both directions, it does not make any intermediate stops. The Tilley Drive Shuttle operates at 60–90-minute headways during peak periods. 14 Old Farm Road Traffic Calming Measures, Lamoureux & Dickinson, May 28, 2020 15 Untitled plan showing existing and proposed shared-use paths together with Old Farm Rd bicycle and traffic calming measures, VHB, March 19, 2021 Lamoureux & Dickinson Page 16 Consulting Engineers, Inc. 8.0 Road & Intersection Improvement Phasing It is anticipated that construction of O’Brien Home Farm Phase Two will begin with the 126 proposed single- family/duplex/triplex residential units in the R1 area. Following that, the remaining residential and commercial development will be market driven. The following presents thresholds for implementing the above identified road and intersection improvements. Kimball Ave / Old Farm Rd Intersection Old Farm Rd and its existing intersection with Kimball Ave has sufficient capacity to support the development of the proposed residential units in the R1 and C1-LR Areas. The principal traffic congestion issue will be queues of westbound traffic on Kimball Ave extending past Old Farm Rd at times during peak afternoon periods due to the relatively short distance between Old Farm Rd and Kennedy Drive. This is an existing condition which is not anticipated to be materially impacted by this initial development phase. Additional development in the C1-LR Area will necessitate relocating the northerly section of Old Farm Rd as proposed so that it intersects Kimball Ave directly opposite the access to the 20-30 Kimball Ave office complex. It is not anticipated that future traffic volumes at the relocated intersection will meet the warrants for signalization until approximately one-half of the projected full-build trip generation in the R-1 and C1-LR Areas is reached. This will necessitate future traffic follow-up monitoring as development progresses. Kennedy Drive / Kimball Ave Intersection It is recommended that this intersection’s existing signal phasing be modified as development of the C1-LR Area and/or the I-C Area commences to provide split phasing of the Kimball Ave and Bayberry Dr approaches. This will improve traffic safety, and is a prerequisite to achieving the future levels of service presented herein. 9.0 Transportation Impact Fees This Project will be subject to paying impact fees which are related wholly or in part to transportation. They include: C City of South Burlington - Road Improvement Impact Fee C City of South Burlington - Recreation Impact Fee C District Environmental Commission #4 - Kimball Ave/Community Dr E Intersection Improvements Impact Fee C State of Vermont Act 145 Transportation Impact Fee. Each will be discussed in the following sections. City of South Burlington - Road Improvement Impact Fee The Road Improvement Impact Fee equals $1,010 per unit for single-family dwellings (which by definition in the LDR’s includes duplexes), $670 per unit for multi-family dwellings and $1,000 per pm peak hour trip end for non-residential development. The actual assessed fees are adjusted each year to credit past and future tax payments per the schedules in the City’s Impact Fee Ordinance. The City’s Road Improvement Impact Fee can be estimated as follows: Single Family Residential Units 126 units $127,260 Multi-Family Units 409 units $274,030 Non-Residential 1,863 pm peak hour trips $1,863,000 Total $2,264,290 Lamoureux & Dickinson Page 17 Consulting Engineers, Inc. City of South Burlington - Recreation Impact Fee A large portion of the Recreation Impact Fee is dedicated to the development of shared-use paths and bicycle lanes. In fact, in the projects identified in the City’s FY 2017-2026 Capital Improvement Program as being funded in part by recreation impact fees, shared use path and bike/ped facility projects account for 77% of the allocated recreation impact fees. The recreation impact fee is assessed only on residential development. The base fee for dwellings in structures containing three or less units equals $1,686 per unit. For dwellings in structures containing four or more units the base fee equals $1,180 per unit. The actual assessed fees are again adjusted each year to credit past and future tax payments per the schedules in the City’s Impact Fee Ordinance. The City’s Road Improvement Impact Fee can be estimated as follows: Single Family & Duplex Units 126 units $212,436 Multi-Family Units 409 units $482,620 Total $695,056 Kimball Ave/Gregory Dr/Community Dr Intersection Improvements Impact Fee This impact fee has been established by the District Environmental Commission #4 to reimburse the FedEx Ground Distribution Center developers for the cost of installing traffic signals and making other improvements at the Kimball Ave/Gregory Dr/Community Dr intersection. The amount of the fee equals $514 per pm peak trip end. This fee may be reduced by 20% since this Project will construct new sidewalks (10% discount) and shared-use paths (10% discount) connecting to existing sidewalks and shared use paths. The discounted fee equals $411 per pm peak trip end. This Project is estimated to generate a total of 433 new pm peak hour trips (at full-build) through this intersection. The resulting impact fee equals $178,050. We also note that this same project is included in the City’s FY 2017-2026 Capital Improvement Program and is shown as being funded in part by the City’s Roadway Improvement Impact Fee. State Act 145 Transportation Impact Fee The Act 145 Transportation Impact Fee was established to provide funding for designated VTrans transportation improvement projects located within a five-mile travel distance of proposed developments. This impact fee is administered by VTrans through the District Environmental Commissions. The impact fee is based on the number of pm peak hour trips that are estimated to travel through the locations of the improvement projects. The number of trips traveling through each highway improvement project were estimated using available pm peak hour turning movement patterns at major intersections. The trips disperse at each intersection; thereby reducing the number of project-generated pm peak hour trips as one moves away from the Project. Detailed pm peak hour trip calculations are enclosed in Appendix Q. Table 18 shows the estimated State Transportation Impact Fees for each transportation improvement project.

Located in a transitional area, it links and complements other neighboring developments. We conclude, based on the analyses performed as part of this TIA, that the existing off-site highways and intersections in the immediate vicinity of this Project have sufficient capacity and safety. This Project will require major improvements, however, to Kimball Avenue both at its intersection with Kennedy Drive and extending eastward to the new I-C Lots Access Drive. Further distant, the traffic impacts of the O’Brien Home Farm Phase Two development will be mitigated by future City and State transportation improvement projects currently under development; towards which Finney Crossing will pay local and state transportation impact fees.
