We have attempted to summarize the features of this property and the components of the Preliminary Plan and Master Plan applications. Application Goals and Components: 1. To create individual lots for each of the thee (3) primary residential structures on the 10.05-acre property. a. The Lot configurations have been made less irregular in comparison to the Sketch Plan review but still has exhibits some bump-outs to reflect the existing conditions while providing equal acreage to the three family members. 2. To create a 1.0-acre common civic space (Community Garden along the most easterly portions of the property. 3. To further subdivide (the most northerly) Lot 1 to create three additional residential lots. a. One of the three new residential lots (Lot 1B) will be co-located with the existing commercial use. i. This differs slightly from the Sketch Plan review which had collocated the existing House (now shown on Lot 1A) with the commercial use. Ms. Marla Keene, P.E. Page 2 of 4 May 8, 2024 b. One of the three lots (Lot 1D) is being depicted with an Accessory Dwelling Unit. 4. The proposed road will be private with the typology chosen to be the “Neighborhood Street – Narrow”, to reflect the proposed reduction in impervious area and limited traffic on this roadway. a. Consistent with the Sketch Plan guidance the applicant is seeking permission to construct the road in two-phases with the second phase extending the road to the southerly property line. 5. The applicant is seeking a determination of Alternate Compliance for the proposed typical section of this street which diverges from the standard typical street section found in the newly published Department of Public Works Standards and Specifications. a. This is concurrently being forwarded to the City Department of Public Works to address the durability and suitability of the proposed revisions. b. Alternate approaches include: i. Substitution of a crushed stone surface in lieu of a bituminous concrete wearing surface. ii. Substitution of a swale in lieu of curbing and enclosed drainage system. iii. Consolidation of the sidewalk and roadway into one surface as part of a shared use design for low volume roadways. c. The proposed use of the Alternate Compliance route is one of the reasons that a PUD approval is sought for this project. 6. The property lies in the Industrial-Open Space District but with the State’s adoption of Act 47 in which residential density is increased to 5 units per acre, the standards of the I-O District are not fitting. a. The applicant proposes the adoption of generally the R4 Zoning district standards for this PUD. 7. The recent amendments to the LDRs and recently published Public Works Standards and Specifications omit the requirement to place street trees. In good faith the applicant is proposing the inclusion of street trees with this application. a. The applicant has also developed a tree retention plan in support of maintaining the existing screening between Hinesburg Road and the existing commercial use on the property. Ms. Marla Keene, P.E. Page 3 of 4 May 8, 2024 8. The Master Plan shows three phases of development with: a. Phase I with 3 additional Single-Family Home units and one ADU (the current Preliminary Plan application) b. Phase II with 3 additional Single-Family home units c. Phase III with 2 additional Single-Family Home units. i. The buildable area calculation indicates a maximum density of 41 units. ii. 11 Units are proposed. 9. Inclusionary Housing requirements outlined Article 18 are not triggered. 10. The property is located in a portion of the City where there are no overlay or natural resource issues other than the wetland buffer that occupies the far east side of the property in the north and south corners. a. The approval calls for the elimination of the most southerly curb cut and the paving of the apron at the commercial access. 12. The project is intended to be a balanced site except for the import of granular materials for the construction of the roadway, driveways, walkways and foundation. The estimated quantity is 420 cubic yards. 13. Water and sewer allocations have been obtained for the Phase I portion of the project. We have provided a summary of the submittal requirement required for both a Preliminary and Master Plan application as outlined in Appendix E of the LDR’s to assist in the review of the features required to be depicted. This cover letter provides a brief summary of the documents that have been developed in support of the demonstration of compliance including:  Article 15A(11) Compliance Narrative  Article 15B Master Plan Compliance Narrative  Master Plan Narrative  Article 15C PUD Compliance Narrative  Article 16 – EPSC Standards  Waiver Request Document  Trip Generation Summaries  Lot Coverage Summary  City Plan Mapping with the Property location shown 11.

All existing pavement markings that become disturbed or overlaid with pavement shall be replaced by the Permit Holder with “in kind” (durable or paint) markings to the satisfaction of the District Transportation Administrator. The Permit Holder shall bear all costs associated with this work. In the event that area lighting proves to be a hazard to the traveling public, the Permit Holder will be ordered to remove or modify it at his or her expense to the satisfaction of the District Transportation Administrator. Upon completion of the work, the Permit Holder shall be responsible to schedule and hold a final inspection. The Permit Holder is required to notify the District Transportation Administrator five (5) working days in advance of such inspection. This permit does not become effective until the Permit Holder records, in the office of the appropriate municipal clerk, the attached “Notice of Permit Action”. The Permit Holder, and their assigns and successors in interest, are obligated by this permit to complete, operate and maintain the access(es) in accordance with the Special Conditions. The Permit Holder shall file a municipal clerk certified copy of the recorded “Notice of Permit Action” within one (1) month of the permit issuance date in the Office of the Development Review and Permitting Services Section. The conditions of this permit and the land uses permitted herein in using the State highway access shall run with the land and are binding upon and enforceable against the Applicant and their successors and assigns. No change shall be made to the design, operation or use of the approved access(es) without a permit amendment issued by the Agency of Transportation or a jurisdictional opinion from the Development Review and Permitting Services Section that a permit amendment is not required. The access must be constructed in such a manner as to prevent water from flowing onto the State Highway. If the access is not constructed satisfactorily, the District Transportation Administrator can order reconstruction of the access at the Permit Holder’s expense. This access will serve as the only access to this property and to any future subdivisions of this property unless approved otherwise by the Agency. The Permit Holder is required to allow a connection and to grant an associated right to pass between the access and adjoining properties (in the future) that will result in a combination of accesses to serve more than one property or lot.

Burlington, VT116, L.S. 0123+55 ~ 0129+36 RT April 25, 2024 Page 3 of 5 In the event traffic from this project increases to the point where traffic signals, additional lanes for turning or any other modifications are necessary, the Permit Holder shall bear the expense of such improvements or facilities. The Agency may require the Permit Holder to update or provide a traffic study to determine if additional modifications are necessary. The Permit Holder is responsible for access maintenance (beyond the edge of paved shoulder). “Access maintenance” will include, but not be limited to, the surface of the access, the replacement and maintenance of the culvert, as necessary, the trimming of vegetation, and the removal of snow banks to provide corner sight distance. In conformance with Vermont Statutes Annotated, Title 19, Section 1111(f), the Agency may eliminate this access in the future where development has burdened the highway system to such an extent that a frontage road or other access improvements (which may serve more than one property or lot) must be constructed to alleviate this burden. The Permit Holder shall bear the expense of the frontage road or other access improvements. The Agency shall determine the need of a frontage road or other improvements based upon and justified by standard Agency procedures. The Permit Holder shall pave the access as shown on the plan. In the event of the Permit Holder’s failure to complete all the work, approved under this permit, by the “work completion date,” the Agency, in addition to any other enforcement powers that may be provided for by law, may suspend this permit until compliance is obtained. If there is continued use or activity after suspension, the Agency may physically close the driveway or access point if, in the Agency’s opinion, safety of highways users is or may be affected. The Permit Holder shall verify the appropriate safety measures needed, prior to construction, so proper devices and/or personnel are available when and as needed. Traffic control devices, shall be in conformance with the MUTCD (Manual on Uniform Traffic Control Devices), Agency standards and any additional traffic control deemed necessary by the District Transportation Administrator. The Permit Holder’s failure to utilize proper measures shall be considered sufficient grounds for the District Transportation Administrator to order cessation of the work immediately. The Permit Holder will perform construction in such a way as to minimize conflicts with normal highway traffic. When two-way traffic cannot be maintained, the Permit Holder shall provide a sign package that conforms to the MUTCD (Manual on Uniform Traffic Control Devices) or Agency standards, as well as trained Flaggers. The District Transportation Administrator may require a similar sign package with trained Flaggers whenever it is deemed necessary for the protection of the traveling public. In addition, the District Transportation Administrator may require the presence of Uniform Traffic Officers (UTOs); moreover, the presence of UTOs shall not excuse the Permit Holder from its obligation to provide the sign package and Flaggers. When traffic control becomes so complex that the traffic control cannot be accomplished using Agency standards, the Permit Holder must submit a traffic control plan to the Agency's Permitting Services office for Agency approval prior to beginning work. The Permit Holder shall ensure that all workers exposed to the risks of moving highway traffic and/or construction equipment wear high-visibility safety apparel meeting the requirements of ISEA DocuSign Envelope ID: C7627C2A-DB8E-40FE-80F6-1F47BCFF446E WGM Associates So.

DocuSign Envelope ID: C7627C2A-DB8E-40FE-80F6-1F47BCFF446E 6 Hi Ed- Keith and Nicole right are proposing a subdivision of their 10-acre parcel located off of VT Route 116 at Mile Marker 2.43 (995 ft North of the Meadowland Drive Intersection) which will create three (3) additional single family home sites and perhaps one or two ADUs in the future. We have attached two location maps and the C1.0 Existing Condition Plan which identifies the existing access locations. The proposed residential road shown on the attached C2.0 sheet will utilize a portion of the existing commercial driveway. No changes are proposed within the Route 116 right-of-way other than a new water service. We are offering this in support of a request for determination on whether a Section 1111 permit is required for the proposed project. Our review of the Permit Listing found the following as it relates to the closest item to addressing access to this property. 2460 VT116 So.

(1) Subdivision boundaries and lot lines must be located and configured to avoid or, where deemed necessary by the DRB, to minimize the subdivision, parcelization, and physical fragmentation of resources located on contiguous parcels, and on the tract or parcel to be subdivided. The proposed residential lots have been designed to avoid these limited features. (2) Contiguous Hazard and Level I Resource protection areas that exceed the minimum lot size The largest wetland buffer area is 7,512 SF which is less than the maximum development density of 5 units /acre or 1 unit per 8,700 SF. must be set aside and identified on the subdivision plat, and in associated legal documents, as “Conservation Lots” to be maintained and managed in single or common ownership, or under a conservation easement held by the City or qualified third party, such as an established land trust. As a condition of subdivision approval, future subdivision of conservation lots shall be prohibited except where all land is being conveyed for conservation purposes, as also noted on the subdivision plat These wetland buffers fall wholly within the proposed Lot 4 Open Space lot. As such, no further identification of the buffers on the plat is necessary. (3) Hazard and Level I resource protection areas must be excluded from the calculation of Buildable Area. Building lots and building envelopes are prohibited within these areas, except as necessary to accommodate resource-dependent facilities (e.g., water and wastewater treatment facilities, public or community recreation facility), as specified under Article 12, or as allowed under this subsection. As outlined in Section 15.A.11(A)(3) the WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 6 of 36 maximum development density calculation has taken these areas into consideration. No Building envelopes are proposed within these areas. (4) A building lot may extend or encroach within a delineated resource protection area only to the extent necessary to meet minimum lot size or frontage requirements for the zoning district in which the lot is located. Not proposed. (5) A building lot may incorporate a Hazard, Level I, or Level II resource area that is less than the required minimum lot size; however, in this case the DRB may require the delineation of a building envelope that excludes the delineated resource area, as shown on the subdivision plat and pinned on the ground, as necessary to limit the siting of buildings, other structures, and parking areas to the developable portion of the lot. Not Proposed. (6) Encroachments within resource protection areas, including transportation and utility corridors, are limited to those allowed, subject to DRB review and approval, under Article 12, Not proposed. (7) A resource protection area may be improved to serve as green infrastructure (e.g., for stormwater management or flood control), or as a public amenity serving the subdivision, consistent with applicable standards under Article 12, to the extent that this does not interfere with its critical natural functions or intended use. Not proposed. 15.A.13 Subdivision Design Process A. Design Process. The design process to be followed by the applicant under this Subsection, in preparing subdivision plans and draft plats included with the application, includes the following steps in order of preference: (1) Delineate and set aside resource areas identified for protection, and other existing site features for consideration under 15.A.12 above. A review for the presence of wetland was completed by Trudell Consulting Engineers (Now Bowman Engineers) and their report indicated that there are no wetlands on the property. They did share an earlier wetland delineation that abuts the east property line at the northeast and southwest corners of the property. Those plans showed a wetland, large enough under the current State Rules, to be considered a Class II wetland. In accordance with the standards outlined in Article 12 section 12.06(B)(2)(a), a 50’ Class II wetland buffer has been added to the plans to reflect the jurisdictional limits. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 7 of 36 (2) Layout and configure the proposed street network to: (a) connect with and extend existing streets; The proposed layout supports the initial phase of re-subdivision of the property along its north third. This application offers a supporting easement across Lot 2 and 3 which will enable the road to be extended to the south when those lots are further subdivided in the future. (b) define one or more contiguous blocks that meet applicable block standards under 15.A.16 or as otherwise specified for the Zoning District, Transect Zone, or type of Planned Unit Development in which the subdivision is located); The proposed Neighborhood Road to be constructed to serve Lot 1B-1D and the southerly extending access road easement will create the potential for a block that has dimensions of 600’ (E-W) x 450’; and to (c) incorporate allowed Street Types and design standards under 15.A.14, including existing and planned streets, sidewalks, recreation paths, and transit stops. The proposed 40’ wide access easement will provide space for a future Neighborhood Road type with adjacent sidewalk. (2) Delineate building lots that front on and are oriented to the abutting street or civic space, and that meet applicable lot size and dimensional requirements by Zoning District, Transect Zone or type of Planned Unit Development or Building Type under Article 11.C, as applicable. This project stands at the cross roads of the current I-O District Lot size standards and the State mandated 5-unit per acre minimum density. This application proposes lot size and setback standards consistent with the R4 zoning district which permits one units per 9.500 SF or 4.58 units per acre. The R4 standards call for: 30’ Front Yard Setback 10’ Side Yard Setback 30’ Rear Yard Setback 15’ Accessory Setback 20% Building Coverage 40% Lot Coverage Maximum Building Height as outlined in Table C-2 The proposed values to be used for this PUD are as follows: 30’ Front Yard Setback 10’ Side Yard Setback 20’ Rear Yard Setback (this fronts a commercial property will no active uses near the common property line) 15’ Accessory Setback (5’ for existing structures) 20% Building Coverage WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 8 of 36 40% Lot Coverage Maximum Building Height as outlined in Table C-2 (4) Designate within each block, or as otherwise provided within the subdivision, required civic spaces, parking lots or facilities, and infrastructure and utility corridors or easements that meet the requirements of these Regulations, which are to be retained in common or single ownership or dedicated to the City. The proposed 1.0 acre Lot 4 is to be held in common ownership as an agricultural use. The community garden will be supported with access easements for all property owners to have access to and for the use of vegetable and/or flower gardens. The community gardens will be maintained and owned by the association (5) Incorporate within block configurations, as applicable, one or more alleys or service lanes, and midblock pedestrian passages as necessary to provide rear, side or shared vehicular and pedestrian access to fronting building lots, civic spaces and designated parking areas or facilities. This will be applicable with the future subdivision of lots 2 and 3 that occupy these areas. 15.A.14 Street Network A. Purpose and Intent. It is the intent of the City to establish and maintain an integrated, interconnected transportation system that efficiently and safely serves all users, including pedestrians, bicyclists, motorists, transit riders and people with disabilities. Accordingly, the applicant must demonstrate that the proposed street network serving the subdivision is consistent with City objectives to: • Maximize network accessibility and connectivity for all transportation modes and users; • Minimize vehicle miles traveled; • Provide adequate emergency vehicle access, and minimize emergency response times; • Limit direct access onto arterial and collector streets, as necessary to preserve and enhance functional capacity; • Create interconnected, walkable pedestrian- and bicycle-friendly residential neighborhoods and mixed use development; • Provide for multiple, direct routes and connections between residential neighborhoods, schools, parks, employment, shopping and other activity centers or destinations; • Incorporate or provide direct pedestrian connections to existing and planned public transit routes for any subdivision and development located within the Transit Overlay District; and to • Accommodate on-street parking where appropriate or required. B. Street Layout. The arrangement of streets serving the subdivision must incorporate and extend the network of existing and planned arterial, collector and local streets in the vicinity, including existing and WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 9 of 36 planned streets serving adjoining subdivisions, and as shown on the City’s Official Map. There are no proposed streets shown on the Official Map or designed as part of the prior subdivision of the surrounding lands in this area. (1) Street Grid. The street layout must establish or extend an interconnected street grid that logically relates to existing site topography, defines walkable blocks, produces useable building lots, reasonable street grades, and safe intersections, incorporates adequate stormwater drainage, and avoids or, where deemed necessary by the DRB, minimizes encroachments within and mitigates adverse impacts to resources identified for protection under Article 12. The proposed access easement along the eastern most portions of Lot 2 and 3 follows the existing topography and supports the creation of a future street block. (2) Street Orientation. The street layout should be oriented to maximize solar access and gain on abutting building lots and block faces while remaining consistent with the existing and planned pattern of development and local topography and completing connections as required by this Article. Longer streets and block faces should either be aligned east-west or north-south, within 20 degrees of true east or true north, in relation to anticipated building lot and building roof orientation. The proposed street to be constructed with the Phase I project runs in the east-west direction while the reserved access easement for the future connector roadway runs in the north-south direction. (3) Existing and Planned Public Streets. The street network must incorporate existing and planned public streets, recreation paths and sidewalks shown on the City’s Official Map; or as required by the DRB if the location, length or function of a proposed street within the City’s street network warrants public ownership. The right-of-way provided for a public street shown on the Official Map must be of a similar location and alignment as that shown on the map, subject to approval and acceptance by the City Council. Planned right-of-way widths listed for public streets under Table 3-1: Planned Street rights-of- way, must also be incorporated in the proposed street layout as applicable. The existing right-of-way width of Hinesburg Road is 66-feet and the planned future width is 80 feet. The plat has been revised to depict the future right-of-way location except for that portion located on Lot 1A as the existing house sits one foot from the existing 66- foot right-of-way. Section 3.2 of the LDRs also requires that the front yard setbacks for lots fronting Hinesburg Road south of I-89 be set at 50 feet. This is also depicted on the Plat. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 10 of 36 (4) Street Connections. The street network must maximize connectivity and provide for the future extension of streets of equivalent functional class and other connecting rights-of- way or easements through adjoining properties upon future subdivision, development or redevelopment. Street rights-of-way must extend to adjoining property lines to allow for future street, sidewalk, recreation path and utility connections. Accordingly: a. Right-of-way connections to properties adjoining the subdivision must be provided along property boundaries at regular intervals, spaced according to functional class, street type and, where applicable, required block lengths unless modified or waived by the DRB under 15.01(C). The modest size of the parent parcel provides a minimal number of connective opportunities. This application has followed prior guidance of enabling a future connection near the southeast corner of the parent parcel (southeast corner of Lot 3. b. In making its determination to waive or modify a street right-of-way requirement, the Board shall consider substitution of a recreation path, sidewalk, or trail right-of-way prior to determination that a full waiver of a right- of-way is warranted. The applicant seeks a conditioned approval that the the physical construction of the connector roadway not be completed with this project in favor of requiring the completion of the road as part of the future development of Lots 2 or 3. c. The DRB shall require that applicant construct a connecting street or recreation path to the property line; or to contribute a proportionate share of the cost to complete construction, in addition to any required impact fees. Where a street or recreation path is identified in the Impact Fee Ordinance, construction of planned improvements may receive credit pursuant to the Ordinance. This application again relies upon a conditioned requirement that the connective roadway be completed when Lots 2 and 3 are developed. d. For phased development, the DRB may approve a street or other right-of-way shown on the subdivision plat and, as a condition of subdivision approval, require that the right-of-way be clearly marked on the ground with one or more signs that indicate its existence and future use; and that construction must occur before any further subdivision or development may be allowed. The plat plan clearly depicts the proposed easement that is to benefit Both Lots 2 and 3 and the City of South Burlington as part of the alignment of a future roadway. Any boulders unearthed during the Phase I construction of the infrastructure on Lot 1 will be placed along the edge of the 40-foot access ease,emt. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 11 of 36 e. The DRB may require temporary turnarounds at subdivision boundaries, designed to City specifications as approved by the City Engineer and Fire Chief. The applicant must then show on the subdivision plat the right-of-way area to be returned to adjacent property owners when street and sidewalk extensions to abutting properties are constructed. This feature has been added to the proposed subdivision plat. (5) Dead-End Streets. Permanently gated streets, dead-end streets, and cul-de-sacs are prohibited unless the DRB finds that physical right-of-way limitations, other legal constraints, incompatible land uses, or Hazards or Level I Resources identified for protection under Article 12 preclude required street connections. This project proposes a temporary hammerhead turnaround at the end of the Phase I street. The proposed temporary hammerhead has been reviewed by the Fire Department. a. Permanent dead-end streets are subject to review and approval by the Fire Chief and City Engineer under these Regulations and other public works specifications and fire codes in effect at the time of application. Not applicable as this is not proposed as a permanent dead-end street. b. A permanent dead-end street allowed under this provision must not exceed two hundred (200) feet in length measured to the center of the turnaround; and must include a turnaround designed to City specifications. Hammerhead turnaround designs are the City’s preferred dead-end configuration. Not applicable as this is not proposed as a permanent dead-end street. C. Street Design. (1) The street network must incorporate allowed Street Types under Article 11.A The proposed street type is Neighborhood Narrow as there is a limited amount of land uses proposed along this road, or as specified by Zoning District, Transect Zone or type of Planned Unit Development, which are consistent with the functional class and the pattern and type of development or uses to be served by the street network. Streets must be designed by a Vermont licensed professional engineer The horizontal and vertical alignment along with the typical section has been designed by a licensed professional engineer. and constructed to City specifications The recently published Public Works Standards provide construction means which this application proposes to follow. The Standards do not cover alternate sections which have been recommended for use by the Department of Public Works for public (or private) streets proposed and constructed in the I-O District. The applicant seeks Alternate Compliance findings for the proposed alternate typical section for Maxine’s Way. Concurrence of this alternate design is being pursued by the Department of Public WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 12 of 36 Works. Proposed street types and functional classifications must be identified on subdivision plans submitted with the application. a. All streets, including both public and private streets, must be designed and constructed by the applicant or developer to City specifications, unless otherwise specifically authorized by the DRB under final subdivision approval. The proposed Neighborhood Narrow Street has adopted all of the written standards as outlined in the LDRs and are further refined within the newly published Public Works Standards. The typical road section proposed with this application has been designed to provide functional durability and proper surface and internal drainage components and varies from the public works standards in that it adopts a more rural based surface water collection system consistent with the most recent road construction improvements guidance in the I-O District guidance set forth by the Department of Public Works for future public streets. The applicant seeks Alternate Compliance findings for the proposed alternate typical section for Maxine’s Way. Concurrence of this alternate design is being pursued by the Department of Public Works. b. In reviewing master plan and subdivision applications, including applications for Planned Unit Development under Article 15.C, the DRB has the authority to require the design and construction of proposed streets to City standards Acknowledged. Please see the narrative outlined in the prior section. the upgrade or improvement of an existing street as necessary to serve the proposed subdivision The Vermont Agency of Transportation controls the access management of VT Route 116 (Hinesburg Road) and is requiring the width and surface material management of the primary access at 850 Hinesburg Road and the elimination of the curb cut at 850 Hinesburg Road.; and the provision of an irrevocable offer of dedication of one or more streets to the City Currently these Phase I and future phase streets are to remain private. However, with the understanding that third parties may benefit from access to these private streets, an irrevocable offer of an access easement to the City of South Burlington will be included with the legal documents to be submitted with the Final Plan application. Any action to accept an offer of dedication shall be the sole authority of the City Council. Acknowledged. c. Public Streets. The DRB shall require a street to be offered for dedication to the City as a public street in accordance with the following: i. The proposed street will or could provide a future extension to an adjoining unaffiliated property or to another existing, proposed, or WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 13 of 36 planned public street. Not applicable as the streets are proposed to remain private. ii. The DRB determines, upon recommendation from the Director of Public Works and Planning & Zoning Director, that the significance of the proposed street within the City’s street network warrants public ownership. Not applicable as the streets are proposed to remain private but this can be revisited. iii. Any street proposed or offered to be public must be built to public standards as enumerated in these Regulations or associated Public Works Standards and Specifications There are no written or published Public Works Standards. d. Private Streets. The DRB may approve, or require, a proposed street to be a private street, as clearly marked on the subdivision plat This is shown on the Subdivision Plat and in any applicable legal documents, in accordance with the following: i. The proposed street will serve lots within a commercial subdivision, master plan, or Planned Unit Development The proposed private street is associated with a proposed PUD project. ii. The proposed street is a dead end street that cannot connect to an adjacent unaffiliated property or street. Phase I is a dead end street but if further development of either Lots 2 or 3 occur, this could become closer to becoming a connected street (to another private street). iii. Homes built on a private roadway may be required to be sprinklered to the satisfaction of the South Burlington Fire Chief. The Fire Marshal has indicated that the buildings will need to be outfitted with a 13D type sprinkler system. All proposed sprinkler systems must be reviewed and agreed upon prior to plat approval. The plans have been revised to indicate that the proposed structures on Lots 1B, 1C and Lot 1D are all to be outfitted with a Type 13D sprinkler system. This requirement may be waived be the DRB upon recommendation by the City of South Burlington Fire Chief. e. Street Types under Article 11.A specify standards that must be followed in designing, redesigning, modifying, or reconstructing a street, except for an existing or proposed public street for which there exists separate engineering plans developed by the City. Street, streetscape, or any other construction or improvements within these street rights-of-way must conform to City engineering plans, as modified by the Director of Public Works. The proposed WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 14 of 36 street type is Neighborhood Street – Narrow. The typical section is one which was utilized in form for the construction of Randall Street – North in the I-O District and subsequently reinforced recently in the construction of Randall Street-South so called (Booska Movers) as part of the planned future connection of the south and north portions as part of a public street system loop. This application seeks Alternance Compliance findings for the use of this type of cross section with the Neighborhood Street – Narrow width standards but no sidewalk. f. All streets must be designed and constructed with sidewalks, greenbelts, bike facilities, medians, travel lanes and on-street parking as specified for each street type, unless an acceptable alternative is approved by the DRB under Subsection (7) below. In support of reducing the amount of impervious surface and maintenance costs, this application seeks approval for a “Shared Use” approach for pedestrian and vehicular use of this roadway in lieu of a dedicated sidewalk. Along the alignment of the proposed road, the first 250 feet is comprised of a crushed stone pavement system. As this has performed extremely well under the large truck loading of the surrounding Wright Trucking Company, the applicant is seeking Alternance Compliance findings to continue this surface material in lieu of bituminous concrete for the remaining portion of Maxine’s way to the east. The street type standard applicable to a proposed street or section of roadway shall be determined by the Development Review Board, in consultation with the Public Works and Planning & Zoning Departments, based on supporting documentation and the following criteria: i. Any street type listed for a specific section of roadway, as shown on the Official Map or the Official Zoning Map, shall be the applicable street type for purposes of these regulations. Not applicable as the Official Map does not show any future vehicular or pedestrian based improvements in this area. ii. The street type must be listed as an eligible or allowed street type as specified by Zoning District, Transect Zone Building Envelope Standard, or PUD type. This is not clearly identified in Table 11-A. iii. The proposed street must conform to the stated intent of an applicable street type and intended uses and activities listed for that type. The description of the Neighborhood Street – Narrow Type is outlined below: WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 15 of 36 Narrow Streets are a special residential street type within the local street network that provides for greater intimacy and ambiance as well as traffic calming because of its limited width. Its application should be targeted to areas where through trips are undesirable or unlikely and where parallel alternative routes are accessible This project seeks to take advantage of these features with the understanding that the future extension of this road will not create a desirable alternate that is otherwise available to traffic currently using the Lane Press Driveway, traveling out to Meadowland Drive and Then Route 116 via 30’ wide roadways. iv. The street type must be consistent with planned, proposed or anticipated connections to or extensions of existing streets. There are City documents which indicate future street connections in this area. v. The street type must be consistent with the specified design speed and design vehicle and accommodate projected traffic volumes at buildout. The stated benefit or creating a traffic calming feature is well suited for this limited use neighborhood. vi. The street type, including associated facilities, must accommodate all anticipated users, including motorists, pedestrians, cyclists and transit riders. Vermont Agency of Transportation Design Standards facilitate Shared Use designs for traffic volumes of less than 100 vehicles per day. The proposed road will support three single family homes and one ADU. Conservatively this equates to an average annual daily traffic (AADT) volume of 40 vehicles per day (VPD). Specifically for roads with less than 100 VPD, the Design Standards call for a two-lane road width of 18-feet with no shoulder and no additional accommodation for bicycles/pedestrians. vii. The street type must conform to Comprehensive Plan policies, and any long range studies, capital plans, and other related city planning and policy documents specific to the street, the location, and the planned pattern of development in the vicinity of the subdivision. The City’s Comprehensive Plan does not identify any specific road improvements in this area which influence this property. g. The DRB is authorized to allow modifications of City street types and standards within a Subdivision, Transect Zone Subdivision or Planned Unit Development, at the request of an applicant, if it finds that the proposed modification furthers stated Comprehensive Plan goals and policies specific to the Zoning District, Transect Zone or PUD type in which the street is located, and that such modification is consistent with provisions for public health, safety and welfare and the orderly development of the City. The narratives outlined in the prior WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 16 of 36 sections indicate that Public Policy guidances provide for the ability to effectively and safely utilize the proposed typical road section. In no case shall a public or private street have a width of less than (20) feet The proposed road is 20’ wide plus two (2) feet wide grassed transitional shoulders . In making such a finding, the DRB may consider, as applicable: i. The stated reasons why a cited standard or specification cannot be achieved; The stated standard of including a sidewalk will create a loss of greenspace while increasing the amount of impervious area to be mitigated. ii. The estimated cost of construction to meet the cited standard in relation to the total project cost, and the cost of any proposed alternative, if cost is cited as a factor in the request; Cost is rarely not a factor in every decision which is made. The cost of constructing a dedicated five (5) foot wide concrete sidewalk is estimated to be $25,200 based on a length of 350 feet from the west edge of the lot 1D driveway and the existing crushed stone surface work yard. iii. Projected traffic volumes, including projected truck, pedestrian and bicyclist traffic, and the minimum standards necessary to accommodate the stated design vehicle(s); The projected vehicular traffic at Lot 1B is 40 vehicles per day. iv. The compatibility of a requested modification with present and anticipated improvements to adjacent street sections or connections; This section of Maxine’s Way may be subject to future traffic increases as outlined in the Master Plan in which Lot 2 which abuts Maxine’s Way may be further subdivided. v. Accident data for the area, to determine the potential impact of a proposed modification on safety and accident rates; and any proposed countermeasures that will be employed to reduce the frequency and severity of future accidents; The Vermont Agency of Transportation Route Logs does not identify this as being a high accident rate area. The limited amount of traffic on Maxine’s Way would indicate that this status would not change. vi. Recommendations of the Director of Public Works with respect to the proposed street design in relation to its development context, functional classification, and maintenance. This is being pursued. Any other information the Board deems necessary to render a decision. Notwithstanding the above, the DRB is authorized to approve minor modifications to accommodate physical site WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 17 of 36 constraints and/or existing patterns of development upon review by the Director of Public Works. 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 “D” or better at full buildout. The proposed project is so small in comparison to the standard in which traffic studies are warranted, by inspection, this project will not modify the existing nearby traffic signal (to the north at Tilley Drive) levels of service. The Levels of Service identified at the Tilley Drive intersection for through movements along Hinesburg Road range from A for Southbound and B for northbound. E. Access and Circulation. The applicant must demonstrate that the street network is arranged to meet applicable access management, traffic, and pedestrian circulation standards under these Regulations, including criteria for site plans under Article 14, Transect Zone Subdivisions under Article 8, or a type of Planned Unit Development under Article 15.C; Compliance narrative for Article 15.C is included with this submittal package. and, for state highways, VTrans Access Management Program Guidelines in effect at the time of application The applicant has received a Letter of Intent for the issuance of an Access Permit for the proposed project.. Unless otherwise specified under these Regulations, the street network, including the location and arrangement of streets, must be designed to: (1) Provide a minimum of two (2) entrances or access points from an arterial or collector street to a subdivision with more than fifty (50) dwelling units on four (4) or more lots or within four (4) or more principal buildings, unless otherwise approved by the DRB in consultation with the City Engineer and Director of Planning & Zoning. This project proposes one initial access to an Arterial Street as it proposes only 4 additional units. (2) Separate subdivision entrances by a minimum distance of four hundred (400) feet on either side of a public street, as necessary to ensure safe access and traffic movement into and out of the subdivision. Subdivision entrances on opposite sides of a public street may be allowed by the DRB if substantially aligned with each other. Signalized subdivision entrances must be separated from existing, signalized highway intersections (as measured between the near edges of the driveway and WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 18 of 36 the intersection) based on street traffic volumes: The nearest street/road intersection is 1000 feet away which far exceeds the most restrictive requirement. Table 15-1: Signalized Intersection Spacing Projected Peak Hour Volume (VPH per access lane) Distance (Feet) Below 450 300’ 450-550 350’ 551-650 400’ 651-750 450’ 751 and greater 500’ (3) Provide for street intersections as close to ninety (90) degrees as physically possible. This proposed intersection alignment provides for this requirement. (4) Incorporate offset “T” intersections and other traffic calming measures as necessary to reduce through traffic and traffic speeds within residential and mixed use neighborhoods and to establish terminal views. The master plan street layout provides traffic calming through the use of a small diameter horizontal curve at the change in direction from the east-west alignment to the north-south alignment. Street jogs with centerline offsets of less than two hundred (200) feet on local streets are not allowed unless specifically approved by the DRB, in consultation with the Fire Chief and City Engineer, for purposes of traffic calming. This is not proposed. (5) Provide deceleration, acceleration and turn stacking lanes as necessary to meet specified Level of Service (LOS) standards under (3) above. This is not being required by VTrans. (6) Design intersections and other access points to City specifications to include curb radii necessary to accommodate anticipated vehicle types and speeds while also minimizing pedestrian crossing distances. This intersection is being designed to VTrans B-71B standard for commercial drives. (7) Provide for safe access to abutting properties for motorists, cyclists, and pedestrians, including safe sight distances, access separation distances, and accommodations for high- accident locations. The proposed intersection has acted as a commercial drive without issue for decades. This is not a high accident location. VTrans issuance of a LOI demonstrates suitability for the proposed use. (8) Align access points with existing intersections or curb cuts and consolidate existing access points or curb cuts within the subdivision, to the extent physically and functionally feasible. The number of curb cuts on Hinesburg Road will be reduced with this project. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 19 of 36 (9) Minimize vehicular access points (curb cuts) to abutting properties and building lots along pedestrian-oriented street frontage; and provide, where physically feasible, shared vehicular access to frontage and other abutting building lots via rear alleys, side streets, service lanes, shared driveways, or rear cross connections between adjoining parcels. The Master plan for the development of Lot 2 in conjunction with the infrastructure construction for Phase 1 will provide the opportunity for opposing single family lots to have their driveways along across from each other. F. Street Names and Signs. 1) Names. Proposed streets and street names must be identified on the final subdivision plat submitted with the application. Street names and numbering shall be provided and approved in accordance with the City’s E-911 Ordinance. Maxine’s Way has been proposed for the name of the private street as it does not conflict with any of the existing street names in the City. The applicant will pursue the required process for the formal adoption of this name. 2) Signs. All street signs and posts will be provided and must be installed by the City at the expense of the subdivider. Street and other highway signs must conform to the South Burlington Sign Ordinance and applicable Manual on Uniform Traffic Control Devices (MUTCD standards) in effect at the time of application. Acknowledged. 15.A.15 Sidewalks, Bike Lanes, and Recreation Paths 1. a. Purpose and Intent. As necessary to facilitate pedestrian and bicycle access and circulation throughout the subdivision, and to provide direct pedestrian and bicycle connections to adjoining neighborhoods there are no neighborhoods in the immediate area, the nearest is 1,800 feet via the existing road alignments, public parks the nearest neighborhood park located 2,300 feet from the first new house to the facility within the Rye Meadows subdivision (This neighborhood when permitted was designed to accommodate users located within 1,300 feet of the park), transit stops the nearest commuter stop is at the intersection of Meadowland Drive and the common driveway for Lane Press and Dynapower which is just under 1,800 feet away and in the AM only brings individuals to points south (down to Middlebury), and other community focal points or destinations in the vicinity (e.g., schools, recreation facilities, civic buildings, shopping and employment centers none of these facilities are located near this property), the applicant must demonstrate that subdivision layout and design, including the proposed street network, incorporates as applicable: i. Pedestrian-oriented streetscapes, as defined by Street Type under Article 11.A; The proposed street type is Neighborhood Street-Narrow (NSN) but modified to reflect the rural surroundings and with a road profile consistent with recent guidance from the Department of Public works which eliminates curbs and enclosed drainage WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 20 of 36 systems. Consistent with the low density and VTrans State Design Standards which support “share the road” approach for low volume roads, the applicant is requesting that the dedicated sidewalk associated with the not be required for the NSN. ii. Pedestrian sidewalks, crosswalks, and mid-block crossings that meet ADA requirements; This is not applicable with the waiving of the sidewalk requirement. iii. Interior block pedestrian passages and walkways; Not applicable as this block is not that large. iv. Direct pedestrian access from the street to fronting building lots and civic spaces, and to existing and planned transit stops; The proposed civic (community garden open space) is located to the east. There are no planned transit stops. v. Bicycle access to all building lots The VTrans State Design Standards allows :Share the Road” configurations for low volume roads with design speeds or 25 mph, and existing and planned transit stops; The nearest transit stop is 1/3 mile away and will not bring you into Burlington in the AM. vi. Bicycle lanes, as incorporated by street type Not applicable for NS-N; and vii. Existing and planned pedestrian trails and multiuse recreation paths, as identified in the Comprehensive Plan the Comprehensive Plan shows a shared use path on the west side of Hinesburg Road, or on the City’s Official Map The Official Map does not identity any pedestrian or bicycle facilities in this area. b. Complete Streets. Unless otherwise specified by Zoning District, Transect Zone or PUD type, the subdivision must incorporate sidewalks or recreation paths as required by Street Type under Article 11.A, other City specifications, and Americans with Disabilities Act (ADA) requirements as applicable. The applicant seeks relief from this standard based on the low volume of traffic on Maxine’s Way. i. Where a subdivision is proposed to front along an existing roadway no new undeveloped lots will front along an existing street, all elements of the Street Type from the curb inward shall be installed by the applicant where not present. c. Pedestrian Easement. - A permanent pedestrian easement twenty (20) feet in width may be required by the DRB, as necessary to facilitate pedestrian and bicycle circulation within the subdivision Acknowledged: i. Through any block that is six hundred (600) feet or more in length; ii. As a continuation of a dead-end street; iii. To provide direct pedestrian access to an existing or planned transit stop within or adjacent to the subdivision; or iv. In conjunction with a utility easement. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 21 of 36 d. Additional Easements. - Additional pedestrian or recreation path easements must be reserved, as indicated on subdivision plans, and shown on the subdivision plat, in conformance with planned public trail and recreation path systems included on the Official Map and Comprehensive Plan. The Official Map does not show any improvements in the area and the Comprehensive Plan shows a recreation path on the opposite side of Hinesburg Road. 15.A.16 Blocks and Lots A. Purpose. The layout and configuration of blocks and building lots in relation to the street network establishes the overall pattern of development, including the creation or extension of walkable, pedestrian-friendly neighborhoods and mixed use developments. As such, the configuration of blocks and building lots represent a fundamental component of subdivision design. Accordingly, the applicant must demonstrate that the proposed subdivision incorporates: 1) A street layout or grid under 15.A.14 above that establishes blocks that meet required block standards under these Regulations, including interconnected, walkable blocks and neighborhoods in all residential and mixed use zoning districts, or as specified by Transect Zone under Article 8 or by PUD type under Article 15.C. Following the guidance provided by the DRB during the Sketch Plan review process it was agreed that the proposed road layout master plan would run east-west from Hinesburg Road and then southerly to the south property line to create a block of 450 feet from the centerline of Maxine’s Way to the south property line. 2) Blocks that are configured to accommodate and provide access to building lots that comply with these Regulations. 3) Block faces and building lots that, where feasible, are oriented to maximize solar access and gain; The proposed street layout follows the guidance found earlier in 15A regarding the goals for enabling solar access. 4) Regularly shaped building lots that front on, and minimize lot frontage or width along abutting streets; The proposed principal lots 1, 2 and 3 have been created with the recognition that there are numerous existing accessory structures that enable the equitable division of the land between the three Wright Family siblings. 5) Required civic spaces, parking lots or structures, and utility corridors and other facilities or easements that are intended to be held, managed, and maintained in single or common ownership. These are all identified on the site plans and subdivision plat. B. Blocks. In all Zoning Districts except the SEQ-Natural Resource Protection, Mixed Industrial/Commercial, Industrial-Open Space, Airport, Airport Industrial, Institutional Agricultural, Park and Recreation, and Form Based Code District, As this property is located in WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 22 of 36 the I-O District it is exempted from this requirement and the remining portion has been removed for brevity. C. Lots. All lots must be laid out to logically relate to topography and their intended use or purpose. Building lots must be laid out within existing and planned street and block configurations, in such a way that they can be developed in full compliance with their intended use and these Regulations. Unless otherwise specified under these Regulations as applicable to the subdivision: 1) All proposed lots must be numbered, as shown on subdivision plans and plats. This has been integrated into the plans. 2) The arrangement and configuration of lots must allow for the further subdivision of any remaining developable land on the tract or parcel to be subdivided. Where proposed building lots exceed minimum lot area requirements, the DRB may require that such lots be configured and developed in a manner that allows for further subdivision and infill development. Acknowledged. The proposed lots all exceed the minimum lot size allowed under the 5 unit per acre density provision. 3) Building or other lots for existing or planned public facilities or uses, including public parks, as shown on the City’s Official map or proposed for dedication to the City, must be labeled and shown as such on the subdivision plan and plat. The Official Map does not show any features near this parcel. 4) Unless otherwise specified under these Regulations, a minimum of ten percent (10%) of the total buildable area within the developed portion of any Major Subdivision exceeding two acres in size must be allocated to functionally integrated civic space lots, as shown on the subdivision plan and plat. The minimum required sizing of the civic space area is based on the parcel size of 10.05 acres – 0.69 acres of Type 1 Hazards (Class II Wetland Buffer) – 0.71 acres of proposed road right-of-way (access easement) – 0.30 acres of Proposed future right-of-way (access easement) = 8.35 acres x 10% = 0.835 acres. The proposed size of the civic (Community Garden) space is 1.0 acres. The allowable uses for this area include: Garden plots, accessory facilities/structures (e.g., water source, equipment shed); limited/no parking. a) Required civic space must incorporate one or more allowed Civic Space Types under Article 11.B and meet associated type requirements. From Article 11.B, the proposed civic space is Community Garden. b) Designated civic space lots must have frontage on or pedestrian access from an abutting street. The entrance to a civic space that does not front on an abutting street must be readily visible, apparent, and accessible from the street. The proposed civic space retain frontage on both the existing and proposed extension of Maxine’s Way. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 23 of 36 c) Civic space lots must be identified on the subdivision plat, and in associated legal documents, as Civic Space lots to be maintained and managed in single or common ownership. This callout is shown on the plat. d) For Major Subdivisions under six (6) acres, the DRB may, in its discretion, provide a credit for up to 50% of the required Civic Space area if the Applicant demonstrates a safe, walkable connection to an existing Civic Space or public park that is accessible by the general public and located within five-hundred (500) feet as there are no facilities that meet this requirement this is not applicable and the remaining section has been removed for brevity. 5) The arrangement and configuration of building lots within the subdivision must be consistent with the intended use, street type, and the planned pattern of development for the Zoning District, Transect Zone or PUD type in which the subdivision is located, including the existing or planned street and block network. This layout plays off of the requirements in the I-O District which looks for larger lots and the statutory requirements that enable a density of up to 5 units per acre. All building lots must front on a public or private street, a designated civic space, or a shared courtyard with pedestrian access to the abutting street. All of the proposed lots front om a private street. 6) Building lots must be configured to comply with all relevant lot area, dimensional and lot coverage requirements under these Regulations, including as appliable: • Lot requirements under Section 3.05; Section 3.05 is inserted below for review. 3.05 Lots a) Reduction of Lot Size. - No lot shall be so reduced in area that the lot size, coverage, setbacks, or other requirements of these regulations shall be smaller than herein prescribed for each district b) Lots With No Road Frontage. i) No land development may be permitted on lots which do not have either frontage on a public road or public waters, unless, with the approval of the Development Review Board through a miscellaneous application, such lots have access to a public road or waters by a permanent easement or right-of-way. Ther proposed lots will front on a private road supported by an access easement. ii) The Development Review Board may approve development of existing lots with no frontage on a public street Not applicable and remaining section has been removed for brevity. c) Road Frontage. In order to promote infill development while protecting the character of existing neighborhoods, no lot shall be created without a minimum of 50-ft of frontage on a public road in the following districts: R1, R1-LV, R2, R4, and LN unless authorized under Article 15.C, Planned Unit Development. The property is located is located in the I-O District but has discussed adopting the lot size standards of the R4 District. The proposed access easement for Maxine’s Way is 40-feet in width consistent with WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 24 of 36 the standard outlined in Article 11.A. This project is also being reviewed as a General PUD. d) Existing Small Lots. Not applicable and the remaining portion has been removed for brevity. e) Corner Lots. This will be true for the proposed Lot 1A and Lot 2 in which frontages will occur on both Hinesburg Road and Maxine’s Way. In cases where a lot has frontage on two streets, the lot shall be deemed a corner lot and shall have two frontages. In cases where a lot has frontage on a public street and on a private right-of-way, the lot shall be deemed a corner lot and shall have two frontages. This has been adopted. • Setback and buffer requirements under Section 3.06; Section 6 has been inserted below for conformance review. 3.06 Existing and Planned Rights-of-Way; Setbacks; and Buffers a) General Provisions. The size and dimensions of setbacks shall be as indicated in Table C- 2, Dimensional Standards, unless otherwise provided in these Regulations. This project stands at the cross roads of the current I-O District Lot size standards and the State mandated 5-unit per acre minimum density. This application proposes lot size and setback standards consistent with the R4 zoning district which permits one unit per 9.500 SF or 4.58 units per acre. The R4 standards call for: 30’ Front Yard Setback 10’ Side Yard Setback 30’ Rear Yard Setback 15’ Accessory Setback 20% Building Coverage 40% Lot Coverage The proposed values to be used for this PUD are as follows: 30’ Front Yard Setback 10’ Side Yard Setback 20’ Rear Yard Setback (this fronts a commercial property will no active uses near the common property line) 15’ Accessory Setback (5’ for existing structures) 20% Building Coverage 40% Lot Coverage b) Arterial and Collector Streets. i) Existing and Planned Rights-of-Way. Table 3-1 indicates estimated existing and planned street rights-of-way (ROW). For any proposed redevelopment project adjacent to a street in this Table, This project fronts on Hinesburg Road the relevant WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 25 of 36 front property line shall be measured from the Planned Street ROW. Where the Planned Street ROW exceeds the Existing Street ROW, one half of the difference shall be assigned to each side of the street unless the Development Review Board finds that the street is not centered in its current ROW. Table 3-1: Existing and Planned Streets Rights-of-Way Street Existing Estimated Street ROW (feet) Minimum Planned Street ROW (feet) Hinesburg Road 66 80 The plat depicts the existing Hinesburg Right-of-way and the proposed future 12’ expansion to enable the expansion of the ROW to 80-feet. Please note that the existing house on Lot 1A sits one foot from the existing 66-foot right-of-way. ii) For the arterial and collector streets listed below, minimum front setbacks shall be fifty (50) feet from the edge of the planned street right-of-way. Table 3-2: Streets Requiring a Minimum 50’ setback Street Allen Road Hinesburg Road, south of I-89 Kennedy Drive Spear Street, south of I-189 The front yard setback has been measured off of the future ROW width. All of the existing residences are non-complying as it relates to the front yard setback. Planned Arterial and Collector Streets. Not applicable Planned public arterial and collector streets, as designated by the Development Review Board, shall be subject to the provisions of this Section 3.06 and any frontage requirements. c) Yards Abutting a Planned Street. Yards abutting a right-of-way designated for a planned public street Not applicable as there are no planned public streets and Maxine’s Way is a proposed private street shall have a minimum setback equal to the front setback requirement for the district in which the lot exists, unless the yards abut any of those streets listed in above, in Section 3.06(B)(2) in which case the minimum setback shall be fifty (50) feet from the edge of the planned street right-of-way. d) Setback Calculation. No space which for the purpose of a building or dwelling has been counted or calculated as part of a side, front, or rear setback or open space provision WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 26 of 36 required by these Regulations may be counted or calculated to satisfy or comply with a setback or space requirement of or for any other building. Acknowledged. e) Traffic Visibility Across Yards. No shrubbery shall be erected, maintained, or planted on any lot that obstructs or interferes with traffic visibility. In the case of corner lots, such restricted area shall be the triangular area formed by the lot lines along the streets and a line connecting them at points twenty-five (25) feet from the intersection. This restricted area is depicted on Sheet C2.0 at Lots 1A and 2 (at Hinesburg Road) and Lot 2 at the northeast corner. f) Structures Requiring Setbacks. Except as specifically provided elsewhere in these Regulations, front, side, and rear setback provisions shall apply to all structures, except for fences. Acknowledged. g) Satellite Dishes. Satellite dishes exceeding three (3) feet in diameter shall not be located within the area between a street right-of-way line and the front elevation of a building. Satellite dishes shall be screened. Acknowledged but not proposed. h) Front Setback Area Landscaping for Non-Residential Uses. In the case of nonresidential uses, not more than thirty percent (30%) of the area of the required front setback shall be used for driveways and parking and the balance shall be suitably landscaped and maintained in good appearance. The existing commercial land use which will be situated on the proposed Lot 1B will be screened by the existing house and landscaping on Lot 1A and the landscaping fronting Hinesburg Road. The proposed landscaping plan calls for the retention of this vegetation. Design approaches that that use landscaping elements in the front setback which enhance stormwater infiltration or management are encouraged. No portion of the required front setback shall be used for storage or for any other purpose except as provided in this section. No change from the existing conditions are proposed. In addition, a continuous strip fifteen (15) feet in width traversed only by driveways and sidewalks shall be maintained between the street right-of-way line and the balance of the lot, which strip should be landscaped and maintained in good appearance. The proposed access easement for Maxine’s Way bisects the yard for the Wright Transportation commercial use. The existing driveway for the truck parking area will preclude the introduction of a 15’ wide landscaped island in this area. This provision shall apply also to yards that abut a right-of-way designated for a future street. i) Setback and Buffer Strip Adjacent to Residential District Boundaries. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 27 of 36 i) Setback to residential zoning districts. Any new, reconstructed, or expanded principal building located wholly or primarily in a non-residential zoning district shall retain a setback of not less than sixty-five (65) feet from all adjacent residential zoning districts, unless applicable lots are part of a Master Plan or Planned Unit Development. Not applicable as this project is located in the I-O District and this project is subject to approval as a PUD. ii) Buffer strip. A buffer strip not less than fifteen (15) feet wide within the sixty-five (65) foot setback in subsection (a) shall be installed and landscaped with dense evergreens, fencing, and/or other plantings as a screen. New external light fixtures shall not ordinarily be permitted within the fifteen (15) foot wide buffer area. The only commercial use is located on Lot 1B. This lot also proposes a new residential building which is specifically being designed as an integral relation to the commercial use. iii) The Development Review Board may permit new or expanded nonresidential uses, structures and/or parking areas, and new external light fixtures, within the setback and/or buffer as set forth in (1) or (2) above, and may approve a modification of the width of the required setback and/or landscaped buffer as set forth in (1) above. In doing so the DRB shall find that the proposed lighting, landscaping and/or fencing to be provided adjacent to the boundary of the residential district will provide equivalent screening of the noise, light and visual impacts of the new non-residential use to that which would be provided by the standard setback and buffer requirements in (1) above. However in no case may the required side or rear setback be reduced below the standard requirement for the zoning district in which the non- residential use is located. Acknowledged but not proposed. j) Exceptions to Setback and Lot Coverage Requirements for Lots Existing Prior to February 28, 1974. The following exceptions to setbacks and lot coverages shall be permitted for lots or dwelling units that meet the following criteria: the lot or dwelling unit was in existence prior to February 28, 1974, and the existing or proposed principal use on the lot is a single-family dwelling or a two-family dwelling. Not applicable and the remaining section has been removed for brevity. k) Front Setback for Front Decks and Porches in the R4 District This property is not located in the R4 district although the goal has been to adopt many of those design requirements for this project in light of the State statutory change in the maximum allowable residential density. In the R4 District, an open porch or deck that shall not exceed the width of the building face to which the porch or deck is attached and that shall not have a depth greater than 12 feet as measured from the building face, shall have a minimum front setback of 10 feet. Access steps not greater than 5 feet in width WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 28 of 36 may project no more than 5 feet in front of the porch or deck, but in no case shall be located closer than 5 feet from the front property line. An enclosed porch, or an open porch or deck exceeding 12 feet in depth, shall be considered part of the principal building and subject to standard front setbacks. The applicant asks that as a condition of approval that section 15.A.16 (C)(6)(k) be available for use for the project. l) Side Setbacks for attached Dwelling Units. Side setbacks do not apply to lot lines co- existent with shared/party walls between attached dwelling units. Not applicable. • Lot requirements specific to an allowed use under Article 14; Not Applicable • Zoning district dimensional standards under Appendix C-2; The R4 District was chosen as the closest standard for a 5 unit per acre density obligation. The proposed dimensional standards have been previously outlined in this document. • Transect Zone Building Envelope Standards under Article 8; Not Applicable • SEQ Subdistrict standards under Article 9 Not Applicable; and • PUD or Building Type standards under Article 15.C and Article 11.C. Acknowledged and addressed in Article 15.C compliance review document. 7) 8) Unless otherwise specified under these Regulations, building lots must have sufficient developable area to accommodate proposed building types, associated yard or other required open space areas, site drainage, utilities, or other improvements required under these Regulations, including site plan standards under Article 14. Acknowledged. Accommodations have been made for utility easement areas. All lots are greater than the minimum allowable lot size. 9) A building lot generally must be rectangular in shape, with side lot lines that are perpendicular or radial to the abutting street, and rear lot lines that parallel the street, except as necessary to accommodate existing rights-of-way or other physical site constraints (see Figure 2-1, Lots, Yards and Lot Lines). Irregular or oddly shaped building lots, including flag and through lots, are prohibited, except for: a) A flag lot Not applicable as no flag lots are proposed., with a minimum of fifteen (15) feet of frontage on the abutting street, as necessary to accommodate a back-lot subdivision and infill development within an existing subdivision, block pattern, or development; b) A triangular or trapezoidal building lot defined by abutting streets that otherwise has sufficient street frontage and lot area to meet minimum lot requirements Not proposed/; or WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 29 of 36 c) A through lot with frontage on two parallel or intersecting streets that cannot be further subdivided under minimum lot requirements, provided that front setback requirements can be met on both streets. Not applicable. 10) Building lots should be oriented and configured to minimize lot width (frontage) along the street. The preferred building lot width to depth ratio is 1:2; however, a ratio of 1:1 to 1:5 may be allowed as necessary to accommodate physical site constraints, stormwater drainage, or rear lot access and parking. The lot ratio configurations are as follows: Lot 1A 135 86 1.57 Lot 1B 205 291 0.70 Lot 1C 198 115 1.72 Lot 1D 195 162 1.20 Lot 2 660 204 3.26 Lot 3 657 194 3.39 The applicant seeks a waiver for the lot ratio for Lots 1A, 1B, 1C, 1D 2 and 3 to reflect the inherent existing conditions associated with the existing limiting conditions and equitable distribution of area between the three relatives. The subdivision will make the individual homes more complying by being located om their own lots. 11) Building lots must be configured to avoid or, where necessary, minimize rear lot lines that abut side lot lines. Unless otherwise specified under these Regulations, corner lots must be configured to meet lot frontage and front setback or build-to-zone requirements on all abutting streets. This has been accommodated in the proposed design. (12) Temporary or permanent surface parking lots, where parking is the principal use, must at minimum meet the minimum lot area requirement applicable to building lots, to allow for future parking lot redevelopment. Such lots must also be shown on subdivision plans and plats submitted with the application. The parking for the trucks and trailers is to be found on Lot 1B in the same location as the existing conditions parking facility. 15.A.17 Mix of Dwelling Unit Types A. Mix of Dwelling Unit Types and Architectural Features. A mix of dwelling unit types (i.e. cottage, single family, two-family, small multi-family, townhouse, etc. etc.) and mix of architectural features and styles must be provided within neighborhoods and developments. These must be mixed within blocks, along the street and within neighborhoods rather than compartmentalized into sections of near-identical unit types. An applicant for a subdivision shall submit a plan demonstrating how this mix will be achieved for the Development Review Board’s consideration at the preliminary plat stage. Where a WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 30 of 36 Planned Unit Development approved under Article 15C establishes standards for a mix of dwelling unit or building types, those standards shall supersede these herein. The limited number of proposed units reduces the practical application of this requirement. The applicant is proposing to integrate at least one accessory dwelling unit (ADU), essentially a cottage type unit, as part of the mix of proposed single-family homes. This is further addressed in Article 15.C compliance review document. 15.A.18 Infrastructure, Utilities, and Services a. Capacity of Community Facilities, Utilities and Services. - The applicant must demonstrate that the proposed subdivision and development will not exceed the existing or planned capacity of, or cause a disproportionate or unreasonable burden on City facilities, utilities and services, including: • Public schools The project will create a very small number of lots., • Police, fire protection and ambulance services, The applicant has met with the Fire Department and has integrated the required turn-around configuration, and sprinkler requirements for the buildings. • Street infrastructure and maintenance, This is to be a private street which will have no impacts on the maintenance obligations of the City. Access is managed by the Vermont Agency of Transportation. • Parks and recreation facilities There are no nearby parks or recreation faciliites to be impacted., and • Water supply, wastewater disposal, and stormwater management systems and infrastructure. Water and sewer allocations have been acquired and the stormwater management has been designed in accordance with the State Stormwater Manual. b. Potable Water Supply and Wastewater Systems. The applicant must demonstrate that adequate potable water supply and wastewater facilities exist to serve the subdivision at buildout, and for each phase of development, in accordance with the following: i. A subdivision within the City’s public water supply and wastewater system service areas must be connected to municipal systems unless physical constraints preclude such connection The proposed project will tie into the municipal water distribution system. For the sewer system this includes any area located within the City Center Service Area, or within 200 feet of an existing sewer line All of the proposed lots and the three existing homes served by on-site wastewater disposal will be tied into the municipal sewer collection system.. Each building lot within the subdivision must be served by the municipal system as required under the City’s Water Ordinance, and South Burlington Ordinance Regulating the Use of Public and Private Sanitary Sewerage and Stormwater Systems, as most recently amended. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 31 of 36 ii. Private community or other onsite systems are not permitted within the City’s existing public water supply and sewer service areas Not applicable. iii. Existing or planned water supply and wastewater system capacity must be adequate to meet total water demand and wastewater flows at buildout, and for each phase of development, as evidenced by City allocations of available reserve capacity for projects connecting to municipal systems. The applicant must apply to the Department for a preliminary allocation of available uncommitted water and wastewater system reserve capacity in advance of preliminary subdivision review. These water and sewer allocations have been acquired. 1. Preliminary capacity determinations are not binding on the City but may be used by the applicant and DRB to determine that system reserve capacity, at the time of application, is sufficient to serve the proposed subdivision. Final capacity allocations will be issued by the Department only after the DRB issues final subdivision approval. Acknowledged. 2. Capacity allocations are not transferrable, and unused allocations expire with the expiration of final subdivision approval, or within (5) years of the date of issuance, unless a one-time extension of up to five (5) years is requested and approved by the Department. Acknowledged. iv. Proposed mains, distribution lines and connections to the City’s water distribution and wastewater systems, and associated equipment and appurtenances, must be designed to City specifications by a Vermont registered engineer, and are subject to review and approval by the Public Works Department. The project will be served by a shared service line capable of providing the required sprinkler flows and pressure at each unit. v. Utility corridors and easements must be shown on subdivision plans and plats submitted with the application These have been depicted on the subdivision plat.. Water and sewer mains must be located within the limits of public rights-of-way or, with approval of the DRB and the Department of Public Works: These are proposed to be privately owned and maintained utilities and there is no public right-of-way to locate them. 1. within other property owned by the City; or 2. within a restrictive, perpetual utility easement granted to the City which is of sufficient width to allow Department access for maintenance and repair work. vi. Sufficient water system pressure must be maintained throughout the subdivision, to serve all building lots and to provide for adequate fire protection. A hydrant flow test has been completed to confirm that the proposed buildings can be sufficiently served with both domestic and sprinkler flow and pressure requirements. vii. A water or sewer main must extend across the entire property, to the adjoining property line, to allow for future extensions through adjoining properties. The sewer main has been extended to the eats to the existing property lien and the water service line has been extended to the east end of the site to enable future extension to the east. WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 32 of 36 viii. The DRB, in consultation with the Department of Public Works and Planning & Zoning Department, may also request that the applicant overdesign required system improvements, including pipes and pumping stations, as necessary to also serve adjoining parcels, or to comply with planned system improvements, subject to review and approval by the City Council. There are required pump stations. The 800 Hinesburg Road property to the north is served by Gravity sewer and its own water main immediately north of this property. The Lane Press and Dynapower buildings are served by gravity sewer and there own dedicated water main immediately on the property to the south. 1. If requested improvements are approved by the City Council in advance of preliminary or final subdivision approval, system infrastructure must be installed by the applicant as approved, and the City shall reimburse the applicant or developer for the difference in cost. Acknowledged. 2. If the City Council does not approve requested improvements, the applicant will not be required to comply with the DRB or Department request. Acknowledged. c. Fire Protection. The subdivision must be laid out to ensure that adequate fire protection can be provided in accordance with City specifications. The applicant has met with the Fire Department and will install Type 13D fire sprinkler system in each building. i. Subdivision layout and design must also comply with applicable City and state public safety and fire codes in effect at the time of application, including standards for minimum separation distances between structures These are all greater than 20 feet, street width The 20-foot width complies with NFPA 1 design requirements, water flow and pressure Adequate flows and pressures have been confirmed with the benefits of the results from the recent Hydrant flow test. , fire hydrant installation None are proposed, the existing hydrants along Hinesburg Road will be utilized, sprinkler systems 13D sprinkler systems will be installed in each building, and emergency vehicle access The temporary hammerhead turn-around has been sized to meet DPW standards. ii. Fire hydrants connected to the municipal water system must be located and designed to meet City specifications, as recommended by the Department of Public Works and City Fire Marshal. For a subdivision that is not connected to the municipal system, the DRB may require the subdivider to install hydrants, fire ponds or other measures necessary to provide adequate fire protection, as recommended by the Fire Marshall (sic). Type 13D sprinkler systems will be installed at each building in accordance with the applicant’s coordination meeting with the Fire Department. d. Stormwater Facilities. The applicant must demonstrate that stormwater management system serving the subdivision has been designed to meet City standards and WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 33 of 36 specifications under Article 13 of these regulations and the South Burlington Ordinance Regulating the use of Public and Private Sanitary Sewerage and Stormwater Systems. The applicant is required to comply with the State of Vermont Stormwater Manual as part of the application for and acquisition of a State Operational Stormwater Permit which is the basic requirement set forth in Article 13. i. Planned Unit Developments. For the purposes of determining applicability in Section 13.05B of these regulations, in the instance of a Planned Unit Development, the applicant shall calculate the impervious coverage on the entire PUD, rather than lot or parcel. The stormwater management requirements will apply to all PUDs within the City of South Burlington where one-half acre or more of impervious surface area exists or is proposed to exist. Acknowledged and adopted. e. Utilities and Services. The applicant must demonstrate that subdivision design has been coordinated with utility companies serving the proposed subdivision, as necessary for the DRB to determine that adequate service capacity exists and that the areas identified for utility installation, on subdivision plans and plat, meet the requirements of these Regulations. i. Utility connections must be provided to each building lot, and to other subdivision lots on which service is necessary or required. These are depicted on Sheet C2.2 Site Utility Plan. ii. Utilities must be located within street rights-of-way, or within permanent utility access and maintenance easements identified on subdivision plans and plats. The plat depicts the supporting utility easements. iii. New electrical, natural gas, telephone, internet, cable television, and outdoor lighting systems must be installed underground, unless prevented by ledge or other physical constraints that make burying utility lines impractical. All of the proposed distribution and service lines are proposed to be installed underground as shown on the Site Utility Plan. iv. Utility lines or corridors must be located and designed in a manner that is compatible with the extension of utilities and services to adjacent properties. Both 800 Hinesburg Road to the north and Dynapower and Lane Press to the east are already served by high capacity utility services. The undeveloped lot to the south already has a water main on the property and gravity sewer available along its east property line. f. Street and Sidewalk Lighting. Where provided along local and collector streets, street and sidewalk lighting must be pedestrian-scaled (e.g., 12 to 14 feet in height) to ensure pedestrian safety traveling to and from public spaces. Overall illumination levels should be consistent with the development patterns and character of the neighborhood, with WGM Associates Subdivision Article 15A Compliance Summary May 6, 2024 Page 34 of 36 smooth levels of illumination (rather than hotspots) and light trespass minimized to the lowest level consistent with public safety. No existing or proposed sidewalks or supporting lighting is proposed. g. Renewable Energy Facilities. The applicant must demonstrate that, to the extent physically feasible, reasonable, and as appropriate to its development context, the subdivision has been designed to incorporate best practices that maintain access to and use of renewable energy resources, e.g., to include one or more of the following as indicated on subdivision plans and plats: i. Street and building lots that are oriented to maximize solar access and gain, for passive solar construction or rooftop solar installations. As previously outlined the street system has bene set up in an east-west and north-south layout. ii. Parking lots or structures that are designed and constructed to accommodate electric vehicle infrastructure, including charging stations and solar canopies or rooftop solar installations. There are no proposed parking lost and the extend of the EV Charging station installation will be integrated into each building based on the desire of each property owner. iii. One or more suitable open areas (“solar lots”) within the subdivision that are specifically designated for a ground-mounted community or neighborhood solar installation. There already exists an existing solar array located along the north property line which will be retained. iv. Solar access easements, as necessary to maintain solar access across adjoining building lots or properties. This is being promoted initially by not installing street trees along the south side of the proposed lots. v. Covenants, deed restrictions or other legal mechanisms that require “solar-ready” construction within the subdivision. Not proposed. 15.A.19 Required Improvements a. General Standards.

Acknowledged but no public acceptance of infrastructure is proposed. 15.C Planned Unit Development Compliance Review WGM Associates, Inc. April.23, 2024 Page 7 of 28 i. A PUD must comply with any applicable provision or standard under these Regulations that is not superseded, modified, or waived by the DRB in association with PUD review Acknowledged. ii. A PUD must also comply with other applicable city ordinances and regulations listed under Section 15.A.11(C) Please see the conformance review for Article 15.A in effect at the time of application, including the following, unless modified or waived by the DRB in consultation with city or state officials having shared jurisdiction. a. Official Map. The PUD must incorporate planned public facilities and capital improvements included in the City’s adopted Official Map and Capital Improvement Program (CIP) in effect at the time of application, unless modified or waived by the DRB. The Official Map and the CIP do not call for any improvements or investments in this area. b. Impact Fees. Development within the PUD is also subject to impact fees enacted and levied under the City’s impact fee ordinance; however, if the applicant or a subsequent developer is required, in association with PUD approval, to provide land or to construct a facility explicitly included in the calculation of an impact fee, they may then receive credit against the impact fee in an amount equal to the value of the dedicated land or cost of construction. Acknowledged. iii. Alternative Compliance. One or more PUD dimensional and design standards under this Article may be modified at applicant request for an alternative form of compliance, subject to separate DRB review and approval, to provide the flexibility necessary to address unique site conditions or constraints; to enable compatibility with existing or planned development in the vicinity; or to allow for exceptional and innovative design. Note that alternative compliance does not constitute an exemption from a PUD standard. Allowed modifications include proposed functional or design alternatives that may be considered in place of a specific requirement under this Article, only if the intent of the requirement is met or exceeded. In approving a request for alternative compliance, the DRB must find that the proposed alternative: This will be used for the proposed elimination of the need to place a bituminous surface and curbing on the private road and to construct a dedicated sidewalk on a low volume roadway. Elimination of Bituminous Surface a. Conforms to the intent, description, and defining characteristics of the selected PUD type(s); This proposed modification is not specifically addressed in the PUD standards beyond an implied requirement to conform with the underlying regulations which in turn reference the newly adopted Public Works Standards. Those regulations provide the manner in which the components are to be installed which the applicant will 15.C Planned Unit Development Compliance Review WGM Associates, Inc. April.23, 2024 Page 8 of 28 conform to, but it is also represents products that represent the lowest level of maintenance for a typical City street. The proposed street is not typical (very low volume) and is not to be offered to the City. Under these conditions the DPW’s interests are minimized and the remaining Public Safety issues are relegated to reasonable emergency access. The proposed width of the street is not proposed to be narrowed beyond that called for in the street typology standards and the maximum street gradient called for in the public works standards will not be exceeded. b. Achieves the intent of the PUD standard to be modified; The primary purposes of a bituminous surface is to reduce infiltration, provide a more durable surface for large vehicle use roadways and to reduce surface maintenance requirements for highly travelled roadways. An additional benefit is that the road surface warms up quicker in winter conditions when exposed to sunlight. Low volume roadways can function without a bituminous concrete wearing surface. In fact, the majority of the roads in Vermont function in this way. The balance point of when a road needs a bituminous surface occurs when the amount of maintenance required to keep the gravel (crushed stone surface) road operational exceeds the annualized cost of placing and maintaining the bituminous concrete surface. The maintenance component must take into account the requirement to provide subsequent surface treatments of the bituminous concrete surface to prevent it from losing its flexibility (becoming brittle) and subsequently having to be replaced altogether. A previous white paper study completed for the Town of Shelburne indicated that, all things being equal, that this break point generally occurs when approximately 40 to 50 residential units and associated traffic is travelling on a roadway (See Attached Exhibit H - When to Pave a Gravel Road). For low volume roadways, a gravel surface, or in this case a superior crushed stone surface, can function in a suitable and less expensive manner than a road with a bituminous concrete surface. Surface management of the proposed road is intended to be minimized through the use of an aggressive (3%) crown to remove the surface water from the road surface as quickly as possible. The existing access drive and parking area for the Wright Transportation Trucks are all constructed of crushed stone materials placed over a stabilization fabric. Normally, an intersection with a high volume of turning movements can create a higher level of maintenance. As it turns out, the turning movement of the 100 PSI truck tires (a passenger vehicle tire typically runs at 30-35 psi) for the 15.C Planned Unit Development Compliance Review WGM Associates, Inc. April.23, 2024 Page 9 of 28 Wright Transportation trucks entering and exiting from Hinesburg Road has been managed without issue with the existing crushed stone surface. This application proposes to utilize the same pavement section as that used in the existing infrastructure on this property. This is depicted on Sheet C4.0 Road Profile and Details (Exhibit A). As a condition of approval with VTrans, this application does include the proposed paving of the apron of the road entering out onto Hinesburg Road consistent with design requirements set forth in the attached Exhibit B - VTrans Design Standard B-71B for commercial roads. This is primarily intended to minimize stone (from gravel road surfaces) from being deposited onto the State highway travel surface. c. Results in development that is equivalent or demonstrably superior in function, design, and quality to that required under the standard to be modified; and The proposed design without the use of a bituminous surface is time proven throughout Vermont as being more cost effective and has a lower carbon footprint when the production of the asphalt is removed from the equation for the initial and future phases of the road maintenance. Alternately, some believe that paving of a driveway or roadway, when not structurally required, can provide some aesthetic benefits. d. Does not adversely impact properties, uses or facilities within, adjacent to, or in the vicinity of the planned development (e.g., regarding walkability, traffic, parking, drainage). The DRB in approving an alternative form of compliance may attach conditions as necessary to ensure compliance, or to mitigate any adverse impacts resulting from a proposed alternative. The proposed use of a crushed stone surface will be consistent with the existing conditions which occupy the first 250’ of the existing access way from Hinesburg Road. The proposed use of the road is very low volume (84 VTE, See Page 5 of Exhibit C - Trip Gen Summary, Phase I). This low volume and low speed will mitigate what otherwise could be issues with dust generation or disturbance of the surface. Stormwater runoff is managed with pretreatment and polishing through a gravel wetland in the same manner as a paved road is required to be managed. Alternative Sidewalk a. Conforms to the intent, description, and defining characteristics of the selected PUD type(s); This project is being reviewed a General PUD. More specifically this is also being reviewed under Article 15A as a subdivision. The intent being to be able to provide a safe environment for pedestrians to move along the transportation corridor. The modeled vehicle trip generation (See Exhibit C, Page 5 Trip Gen Summary) for Phase 1 identifies 15.C Planned Unit Development Compliance Review WGM Associates, Inc. April.23, 2024 Page 10 of 28 Maxine’s Way as having 84 VTE at the intersection with Hinesburg Road. Since this will be a dead-end road in Phase I (with this application), the VTE on this road decrease as one moves easterly away from Hinesburg Road. The State of Vermont Agency of Transportation (VTrans) has prepared State Design Guidelines to provide direction of consistent design of roadways. Within this document it specifically indicates that for roadways with design VTE of less than 100 vehicles per day, that bicycle and pedestrian traffic can be accommodated within the roadway surface without additional infrastructure (See attached Exhibit D - VTrans Design Guidelines). This represents a practical balancing of safety conflicts and cost benefit. The AM and PM peak hour generation are respectively 5 and 6 vehicle per hour (Exhibit C – Trip Gen Summary). An average of one vehicle every 10 minutes. With this being a low volume, low speed roadway with width that exceed the recommended minimum, pedestrian and bicycle movements can safely be accommodated within the proposed 20-foot road surface. b. Achieves the intent of the PUD standard to be modified; The intent is to be able to provide pedestrians and bicyclists a safe environment to move through the roadway corridor. As evidenced in the design guidelines outlined above, public policy guidelines indicate that pedestrians and bicyclists can be safely accommodated within the common roadway surface without the need for supplemental infrastructure for very low volume roadways. c. Results in development that is equivalent or demonstrably superior in function, design, and quality to that required under the standard to be modified; and The narrative above addresses the guidance related to a “share the road” approach relative to pedestrian accommodation when associated with a very low volume roadway. From a resource conservation approach, the consolidation of what otherwise would be a separate standalone sidewalk, the applicant’s proposal is notable as it relates to the reduction of impervious surfaces, reduction of high CO2 impact materials (concrete) and dedicated maintenance. d. Does not adversely impact properties, uses or facilities within, adjacent to, or in the vicinity of the planned development (e.g., regarding walkability, traffic, parking, drainage). The DRB in approving an alternative form of compliance may attach conditions as necessary to ensure compliance, or to mitigate any adverse impacts resulting from a proposed alternative. The consolidation of the pedestrian, bicycle and vehicular facilities into one transportation corridor will have no impact on the properties that abut 15.C Planned Unit Development Compliance Review WGM Associates, Inc. April.23, 2024 Page 11 of 28 this proposed PUD due to the remote proximity of the project from their respective transportation facilities. Alternative Drainage and no curbing for Typical Street Section a. Conforms to the intent, description, and defining characteristics of the selected PUD type(s); The specific standards in the LDRs (Exhibit E - Article 11A – Street Typology) speaks to a design roadway width of 20-feet and a design speed of 25 MPH. The proposed road section with this application embraces this width and design speed requirement. However, there is no other guidance on the crown, gradient, curbing or drainage management relative to the 11 different street typologies outlined in Article 11A of the LDRs. The recently published Public Works Standards and Specifications provides only one typical detail for a street section (Exhibit F – DPW Standards.pdf). It shows the use of concrete curbs which in turn requires the use of an enclosed drainage system to collect and convey stormwater runoff. Within the Industrial Open Space District, the Department of Public Works specifically asked that the Randall Street-North (which intersects with Meadowland Drive) typical road section eliminate the curbs in favor of open swales (ditches) on either side of the road. This was most recently reinforced with the Booska Movers approval which adopted for the future public street (Randall Street south) a typical section which eliminated the curbing in favor of roadside swales (See Exhibit G - Booska - C5.3 ROAD DETAILS). The typical design for the Maxine’s Way street section call for the introduction of a swale on the uphill side of the road with a stabilized stone conveyance swale capped with sandy loam disconnection shoulder. The cap includes an linear chimney drain to remove concentrated flows from the surface of the cap to reduce the potential for erosion (See Exhibit A - Sheet C4.0). b. Achieves the intent of the PUD standard to be modified; Normally the intent of the curbing is to delineate the boundaries between road and sidewalk, it serves as a tool for traffic management and to control stormwater runoff. In this case the need for sidewalk separation and traffic control is not required due to the low volume of the roadway. Stormwater management is actually impaired by eliminating disconnection treatment between the road surface and the swale. The elimination of the need for catch basins and enclosed drainage pipe conveyance systems in favor of a swale is more synonymous with natural conditions. The adoption of open swales, when space permits, provides a higher level of Stormwater treatment and a more open feel to the area. 15.C Planned Unit Development Compliance Review WGM Associates, Inc. April.23, 2024 Page 12 of 28 c. Results in development that is equivalent or demonstrably superior in function, design, and quality to that required under the standard to be modified; and Curbs are used in manner urban development scenarios when there is not space to allocate to shoulders and transitional slopes into and out of parallel swales. But is area that have the space to accommodate the features, the use of a grassed shoulder and slope with a parallel swale system to collect and convey the stormwater from the road and surrounding areas, provides an improved level of treatment compared to the curbing and catch basin system. d. Does not adversely impact properties, uses or facilities within, adjacent to, or in the vicinity of the planned development (e.g., regarding walkability, traffic, parking, drainage). The DRB in approving an alternative form of compliance may attach conditions as necessary to ensure compliance, or to mitigate any adverse impacts resulting from a proposed alternative. The proposed elimination of curbing, for those low volume, shared use roadways, will not impact parking (there is no parking allowed on the 20’ wide Neighborhood Street-Narrow typology), will eliminate plow damage of the curbs, especially at driveway intersections, and will augment initial stormwater treatment. It will not impact abutting properties to the PUD and will create a more rural feel consistent with the goals of the family members and to better mimic the open nature of the surrounding properties. Alternative Vertical Profile K Values at end of the Road a. Conforms to the intent, description, and defining characteristics of the selected PUD type(s); The LDRs do identify a design speed for new roads but do not speak to the horizontal or vertical alignment of new roads. The newly published Department of Public Works Standards and Specifications do provide guidance on those characteristics. These design values are documented on Exhibit A - Sheet C4.0 and Exhibit F - DPW Standards - Abridged. For vertical alignment, a design “K-Value” defines the length of the vertical curve connecting two tangent grades. The intent of the “K-Value” in developing the vertical alignment of roadways is to ensure that there is the ability to adequately observe an obstruction in the road and to safely stop. This is controlled by the ability to see over the top of a “crest” vertical curve and for the headlights to see past the low point of a “sag” vertical curve. 15.C Planned Unit Development Compliance Review WGM Associates, Inc. April.23, 2024 Page 13 of 28 K-Values are assigned based on the design speed and associated Safe Stopping Sight Distance. The genesis for most K-Values used in design in the past 70 years is from A Policy on the Geometric Design of Highways and Streets published by the American Association of State Highway and Transportation Officials (AASHTO) (Exhibit I - AASHTO High Vol Geom. Stds - Abridged). In 2001 AASHTO recognized that these standards, initially published in 1954 and subsequently revised and improved upon, had created a conflict with the unique conditions associated with very low volume roads (<400 vehicle trip ends per day). They found that the lower volume roads had lower crash rates and when applying the higher volume road standards to low volume roads, it had created a “less cost effective” design solution. In 2002 AASHTO published the Guidelines for Geometric Design of Very- Low Volume Local Roads (ADT <400) (See J - AASHTO GeoDesign of V-Low Vol. Rds – Abridged). The ASHTO Highway Subcommittee on Design which included over 100 individuals from across the country, including two from Vermont, developed the more case sensitive and appropriate design standards for low volume roadways. Of the 11 design standards set forth in the Public Works Standards, the applicant has adopted 8 of those and is seeking acceptance of alternate design values most appropriate for the unique conditions associated with this application for three (3) of those 11. These are outlined below. Crest Vertical Curve K-Value of 7 - This value is taken directly from the AASHTO Low Volume design guidelines (Exhibit J - AASHTO GeoDesign of V-Low Vol. Rds – Abridged). The K Value identified in the Public Works Standards is associated with the AASHTO guidance for high volume roadways (Exhibit I - AASHTO High Vol Geom. Stds - Abridged)). Sag Vertical Curve of 13 – The sag vertical curve occurs at the far east end of the road where there is only one home. The design speed here will be closer to 15 MPH as one prepares to make the turning movement into the driveway. In the future, if this road is extended to the south, this will likely be a stop condition intersection. Under either scenario, the design speed will be much less than the 25 MPH allocated for a free flowing roadway. We are proposing to assign a design K-Value of 13 for this sag vertical curve. This is greater than the design K-Value of 10 for a 15 MPH design speed found in the High Volume road design standards. The K- Value of 13 also represents the lowest K value which would be associated with maintaining comfort at the design speed of 25 MPH (See Exhibit K - Comfort in Sag Vertical Curves). The K Value identified in the Public 15.C Planned Unit Development Compliance Review WGM Associates, Inc. April.23, 2024 Page 14 of 28 Works Standards is associated with the AASHTO guidance for high volume roadways. Stopping Sight Distance of 115 feet – This plays into the associated K Values recommended by AASHTO for Very Low Volume Roadways. The stopping Sight Distance value identified in the Public Works Standards is associated with the AASHTO guidance for high volume roadways. b. Achieves the intent of the PUD standard to be modified; The intent is to provide a safe roadway under the design conditions. The proposed use of design guidelines better associated with the conditions still achieves the intent of providing a safe roadway. c. Results in development that is equivalent or demonstrably superior in function, design, and quality to that required under the standard to be modified; and A downside of designing low volume roadways with high volume design standards is that the comfortable rate of speed increases which reduces the traffic calming features originally intended in the Neighborhood Street typology. The proposed use of the Very Low Volume Design standards for this extra low volume roadway provides a better assembly of design and function with the proposed conditions. d. Does not adversely impact properties, uses or facilities within, adjacent to, or in the vicinity of the planned development (e.g., regarding walkability, traffic, parking, drainage). The DRB in approving an alternative form of compliance may attach conditions as necessary to ensure compliance, or to mitigate any adverse impacts resulting from a proposed alternative. The proposed use of appropriate design standards provides a significant benefit of improved traffic calming (reduced travel speed, increased safety) for those properties inside the PUD. By the nature of the issue, there will be no impact on properties located outside of the PUD. D. Development Density. i. Intent. A Planned Unit Development is intended to accommodate within a designated Development Area typically higher effective densities of development than the underlying zoning district may allow, as necessary to accommodate: a. The clustering of development to conserve resources identified for protection; b. A more efficient and cost-effective use of land, facilities, services, and infrastructure; Page 1 of 3 CONSTRUCTION AND EROSION CONTROL STANDARDS 16.01 Purpose 16.02 Applicability 16.03 Standards for Erosion Control during Construction 16.04 Excavation and Grading 16.01 Purpose It is the purpose of this Article to provide standards for proper erosion control and landscaping during and after land development activity in the City in order to prevent the adverse effects of erosion and runoff on the City’s residents, surface waters, and air quality. 16.02 Applicability Nothing in this Article shall be interpreted to supersede applicable permit conditions in an applicable permit issued by a superseding authority, including but not limited to those issued by the Vermont Department of Environmental Conservation or a permit issued by the Vermont Environmental Board pursuant to 24 VSA Chapter 151 (Act 250). Acknowledged. 16.03 Standards for Erosion Control during Construction A. Natural Cover. Land shall be subdivided and improved in reasonable conformity to existing topography in order to minimize grading, cut and fill, and to retain, insofar as possible, the natural contours, and to limit storm water runoff, and to conserve the natural cover and soil. The proposed project is comprised of smaller single family homes which enables the improvements to steps down the 10% gradient. After application for approval has been submitted to the Development Review Board, no topsoil, sand or gravel shall be removed from the subdivision for any other purpose than to meet construction needs of that particular subdivision or to meet any requirements of these regulations. No material is anticipated to be removed from the site. The only import will the granular materials required for the infrastructure constriction. B. Erosion and Sediment Control. (1) The smallest practical area of land should be exposed at any one time during development. When land is exposed during development, the exposure should be kept to the shortest practical period of time. Areas of disturbance must have temporary or permanent stabilization within 21 days of initial disturbance. This goal is iterated in supporting EPSC narrative and the temporary stabilization requirement is no less than 14 days after work on an area has ceased. (2) Land shall not be left exposed between October 15 and April 15. The project will be required to comply with the Winter EPSC management requirements which calls for daily stabilization during this time period. (3) Where necessary, temporary vegetation and/or mulching and structural measures shall be required by the Development Review Board to protect areas exposed during the development. This approach is included in the EPSC management narrative on Sheet C3.1. (4) Sediment basins (debris basins, desalting basins, or silt traps)shall be installed and maintained during development to remove sediment from run-off water and from land undergoing development. Page 2 of 3 One of the first requirements will be to shape the Gravel Wetland basin to be used initially as a sediment basin until the site has been stabilized. (5) The permanent final vegetation and structures shall be installed as soon as practical in the subdivision. Exposed soil must be seeded and mulched or covered with erosion control matting within 48 hours of final grading. This out outlined on Sheet C3.1 Section 4. (6) Adequate and permanent measures shall be taken at culvert outfalls to minimize or prevent erosion and disruption of drainageway areas. These BMPs are depicted on Sheet C3.0. Supporting details ar eon Sheets C3.1, C3.2 and C4.3 C. Site Restoration. After completion of construction, suitable grading or seeding shall be done to restore the condition of any disrupted portion of a site. This is outlined on Sheet C3.0 and the narrative on Sheet C3.1. 16.04 Excavation and Grading A. General. All excavating and filling required for construction of improvements shall be as specified within this Section. The entire area of work shall be brought to the required lines and grades by excavation or filling. Excavation material, if suitable, may be used in making embankments and in filling low areas. A minimum of four (4) inches of top soil shall be provided to cover overall finished slopes. This material shall be spread uniformly over all finished slopes. All streets shall be graded from property lines to property line to approved grade and cross section. Acknowledged. Topsoil placement is called out on Sheet C3.0. B. Fill. No stumps, wood, roots, sod, other fibrous materials or refuse shall be used as fill. Acknowledged. There won’t be much issue here as there are no tree to be removed. C. Embankments. Embankments shall be formed of suitable and acceptable excavated materials and brought to the required lines and grades. The materials for embankment shall be placed in successive horizontal layers not exceeding six (6) inches in depth extending across the entire fill area. They shall be spread by a bulldozer or other acceptable method, and shall be thoroughly compacted. Where embankments are made of rock, the rock shall be so deposited that all voids are filled with earth and in such a way that the compaction specified above may be secured. The earthwork requirements are outlined in the specifications on Sheet C5.0 D. Subgrade. Upon completion of filling and excavating, the subgrade shall be formed to the required grade and contour, and the entire surface again rolled as specified above. High spots shall be removed and low spots filled with the acceptable material and the process of leveling and rolling continued until no further depression results. The earthwork requirements are outlined in the specifications on Sheet C5.0 E. Side Slopes. Side slopes in embankments and on roadside drainage ditches shall descend one (1) foot vertically for at least each two (2) feet horizontally (2 on 1). Side slopes for this project are to be at least 3:1. Surplus material resulting from excavation of the road prism shall be used to flatten slopes of embankment so that they ascend one (1) foot vertically for at least (2) feet horizontally (2 on 1) Acknowledged. Side Page 3 of 3 slopes in excavation rock shall ascend six (6) feet vertically for at least each one (1) foot horizontally (1 on 6). There is no rock to be excavated on this project. Where rock cuts have a face higher than ten (10) feet vertically, a three (3) foot berm shall be provided at each ten (10) foot level above the grade at the edge of the pavement. Not applicable. Side slopes shall not be graded so as to extend beyond the limits of the street right-of-way onto land not part of the subdivision unless a suitable slope easement has been properly established and granted by the affected property owner. Acknowledged but not applicable.
