Preliminary Plat Application #SD-21-22 was approved on October 11, 2021. The project is subject to the LDR adopted December 28, 2020. The Project is located in the Southeast Quadrant Natural Resource Protection district. The applicant is proposing a four lot subdivision. The preliminary plat proposed a three lot subdivision. The proposed final plat involves establishing a fourth Conservation lot as its own lot instead of being combined with one of the house lots. The subdivision is largely governed by LDR 9.12, which allows lots that have been in existence since June 22, 1992 to be subdivided and developed with one or more detached single family units subject to conditional use review if they meet certain standards, discussed below. This property has been in existence in its current form since before June 22, 1992 therefore subdivision is allowed. CONTEXT The property is located in an area exempt from Interim Zoning. The property is located in the Natural Resource Protection district. Development within the SEQ-NRP district is permissible pursuant to a conservation plan approved by the Development Review Board (Section 9.12A and 9.12B). No portion of the development may be within a primary natural community or its related buffer. Such development is subject to DRB approval of a conservation plan that balances development or land utilization and conservation. On an overall basis, the applicant proposes to construct three homes with a shared driveway. The applicant is proposing that the three homes be relatively clustered together, and that the remaining lands remain in agricultural use and be permanently conserved. COMMENTS Development Review Planner Marla Keene and Planning and Zoning Director Paul Conner (“Staff”) have reviewed the plans submitted and offer the following comments. Numbered items for the Board’s attention are in red. A) ZONING DISTRICT STANDARDS 9.12 SEQ-NRP SUPPLEMENTAL REGULATIONS A. Any lot that lies entirely within a SEQ-NRP sub-district is subject to the following supplemental regulations: (1) Such lot shall be conveyed to the City of South Burlington as dedicated open space or to a qualified land trust and shall not be developed with a residence, or (2) Such lot may be developed with a residence or residences pursuant to a conservation plan approved by the Development Review Board. See 9.12(B) below. #SD-22-07 Staff Comments 3 3 of 13 (3) Such lot may be developed with uses other than residences, as listed in Table C-1, subject to the Development Review Board’s approval of a conservation plan that balances development or land utilization and conservation. Such lot may also include the following additional development/activities: (a) Driveways, roads, underground utility services, or other appurtenant improvements to serve approved development or uses. Utility service components, such as transformers and amplifiers, may be installed at ground level where such accords with standard industry practices. (b) Landscaping, regrading, or other similar activities necessary to the creation of a buildable lot. The applicant is proposing to conserve the property and restrict development to a limited portion of the existing parcel. They have provided a draft conservation easement which provides restrictions over the parcel. The conservation easement has a general agricultural intention, and includes a number of exceptions, as follows. • a farmstead complex consisting of non-residential buildings • farm labor housing consisting of three (3) single family homes • additional farm labor housing that can be converted to farm related uses when not in use as housing • additional minor structures for the purpose of non-commercial periodic camping or hunting purposes The full draft conservation easement is included in the packet for the Board. Staff recommends the Board include a condition that while the conservation easement allows for additional farm labor housing beyond the three proposed herein, no such approval is granted with this application and would instead be the subject of an amendment should the applicant wish to pursue it at a later date and if it were ever allowed by the LDR. Since the conservation plan will become a permanent restriction through non- regulatory modes, Staff has no concerns about retaining a future private allowance, and considers the conservation plan meets this criterion. B. A lot that was in existence on or before June 22, 1992 and which lies substantially or entirely within a SEQ-NRP sub-district may be improved with one or more single family detached dwelling units, subject to conditional use review and the following supplemental standards: (1) N/A (2) Where the lot is fifteen (15) acres or more in contiguous area, the Development Review Board may allow a subdivision of no more than three (3) lots and construction of one (1) single family dwelling unit on each of these lots only if: The applicant is proposing four lots but one is purely for the purpose of conservation. See additional discussion below. a. The DRB shall determine whether the portion of the lot in any non-NRP SEQ sub-district is sufficient to accommodate the construction and use of at least three (3) single family dwelling units on lots approvable in compliance with these Regulations. No portions of the lot are outside the NRP sub-district. Staff considers this criterion met. b. such lots shall have a minimum size of 12,000 square feet per dwelling unit, and, #SD-22-07 Staff Comments 4 4 of 13 Staff considers this criterion met. c. the location of structures, yards, and access drives have no portion within a designated primary natural community or its related buffer, and, This standard refers to the natural communities identified in the 2005 Arrowwood Environmental Report, included in the packet for the Board. Staff considers this criterion met. d. The location of structures and access drives are clustered such that no dwelling unit is located more than one hundred (100) feet from any other structure, and, The applicant has requested waiver of this criterion to allow homes to be located in a line, with the homes approximately 100-feet apart in a line, placing the outermost homes more than 250 feet apart. At preliminary plat, the Board granted waiver of this criterion because of the applicant’s testimony that they believe this configuration is best because of ledge, existing trees, and requirements of wastewater disposal systems. No changes affecting this criterion have been proposed. e. The dwelling units shall be detached single family dwellings, and, Staff considers this criterion met. f. Such subdivision plan shall be subject to the Development Review Board’s approval of a conservation plan in a form acceptable to the City Attorney that permanently encumbers the land against further land subdivision and development. The applicant is proposing to subdivide off the lot proposed for conservation as its own lot, Lot 1. The purpose of the lot is conservation, and the only development on it consists of driveways, roads, underground utility services, landscaping, and regrading necessary to the creation of a buildable lot that the Board (elements allowed on lots within the SEQ-NRP subject to the Development Review Board’s approval of a conservation plan). The LDR clearly allows for 3 building lots and requires a conservation plan. The LDR also actively supports the conveyance of land to a qualified conservation entity, which most cleanly takes place as its own lot, and so Staff considers this to be a desirable arrangement. 1. Staff recommends the Board allow this additional lot as a conservation lot in addition to the three development lots. 9.06 SOUTHEAST QUADRANT DIMENSIONAL AND DESIGN REQUIREMENTS APPLICABLE TO ALL SUB- DISTRICTS. The following standards shall apply to development and improvements within the entire SEQ. A. Height. See Article 3.07. Article 3.07 states that the requirements of Table C-2, Dimensional Standards, apply for the maximum number of stories and the maximum height. Waivers are not available for structures with the SEQ zoning district. At preliminary plat the Board found that the applicant must demonstrate building heights at the time of application for each zoning permit. B. Open Space and Resource Protection. (1) Open space areas on the site shall be located in such a way as to maximize opportunities for #SD-22-07 Staff Comments 5 5 of 13 creating usable, contiguous open spaces between adjoining parcels The applicant is proposing to cluster the three homes near the north end of the site. The applicant has modified the lots slightly compared to preliminary plat due to a revised wastewater disposal system but otherwise has retained a substantially similar conservation area, including the provision of building envelopes. The proposed driveway on Lot 1 crosses a Class II wetland buffer. 12.02E. Standards for Wetlands Protection (1) Consistent with the purposes of this Section, encroachment into wetlands and buffer areas is generally discouraged. The applicant has determined, in cooperation with Tina Heath of the VTANR Wetlands Program, that there is an existing class II wetland in proximity to the proposed private access road for the three development lots. The State wetlands program determined the wetland and its 50-ft buffer are exempt from State regulation at this time due to an agricultural exemption. However, if the applicant were to disturb the wetland for the currently proposed project, the wetland and buffer would become jurisdictional. Therefore the applicant has modified their plan to remove impacts to the Class II wetland in order to preserve State exemption status. The City’s wetland rules do not include the agricultural exemption employed by the State. Therefore, impacts to wetland buffers are subject to the standards of 12.02E. 2. The Board at preliminary plat found that the applicant must supply the area of proposed Class II buffer impacts at the final plat stage of review. The applicant has not supplied this information. Staff recommends the Board require the applicant to supply this information prior to closing the hearing. (2) Encroachment into Class II wetlands is permitted by the City only in conjunction with issuance of a Conditional Use Determination (CUD) by the Vermont Department of Environmental Conservation and positive findings by the DRB pursuant to the criteria in (3) below. No Class II wetland impacts are proposed. (3) Encroachment into Class II wetland buffers, Class III wetlands and Class III wetland buffers, may be permitted by the DRB upon finding that the proposed project’s overall development, erosion control, stormwater treatment system, provisions for stream buffering, and landscaping plan achieve the following standards for wetland protection: (a) The encroachment(s) will not adversely affect the ability of the property to carry or store flood waters adequately; (b) The encroachment(s) will not adversely affect the ability of the proposed stormwater treatment system to reduce sedimentation according to state standards; (c) The impact of the encroachment(s) on the specific wetland functions and values identified in the field delineation and wetland report is minimized and/or offset by appropriate landscaping, stormwater treatment, stream buffering, and/or other mitigation measures. The applicant described the functions and values of the wetland at preliminary plat, and the Board found this criterion met. No changes to the proposed impacts have been made therefore Staff considers no changes to the Boards previous findings to be necessary. #SD-22-07 Staff Comments 6 6 of 13 (2) Building lots, streets and other structures shall be located in a manner consistent with the Regulating Plan for the applicable sub-district allowing carefully planned development at the average densities provided in this bylaw. The subdivided property may only be developed with three single family dwelling units as discussed under 9.12 above. Staff considers this criterion met. (3) A plan for the proposed open spaces and/or natural areas and their ongoing management shall be established by the applicant. See discussion under 9.12 above. (4) Sufficient grading and erosion controls shall be employed during construction and after construction to prevent soil erosion and runoff from creating unhealthy or dangerous conditions on the subject property and adjacent properties. In making this finding, the Development Review Board may rely on evidence that the project will be covered under the General Permit for Construction issued by the Vermont Department of Environmental Conservation. The applicant has provided an erosion prevention and sediment control plan. The City Stormwater section reviewed the provided erosion prevention and sediment control plan on May 27, 2022 and provided the following comments. 1. Per the page 117, of the VT Standards and Specifications for Erosion Prevention and Sediment Control Manual (VTDEC, Feb 2020), the maximum allowable slope length of contributing runoff to a silt fence placed on the slope shown on the site plans (~8%) is 100ft. The site length exceeds 100’ and a second row of silt fence should be added closer to the building construction activities. 2. Plans should show the limit of construction disturbance. 3. It is not clear where on the site the stone-lined swale labeled section A-A on the Stone Check Dam detail on page 4 is to go. This detail shows rock size of 2”-6”. The typical ditch detail shown on page 3 looks to be the one intended for the stone-lined ditch that outlets stormwater to the south/east. This typical calls out Type 1 Stone (up to 12” rock size). Plans should be clear about which typical detail is intended for each swale. 4. It is not clear where on the site plan the typical stone spillway detail is intended to be placed. 5. It is not clear if the ditch on the north side of the private road is to be stone-lined or vegetated between stone check dams. 6. Plans should include a detail for rock outlet protection for both 15” drainage outlets. Staff recommends the Board require the applicant to address the comments of the City Stormwater Section as conditions of approval. (5) Sufficient suitable landscaping and fencing shall be provided to protect wetland, stream, or primary or natural community areas and buffers in a manner that is aesthetically compatible with the surrounding landscape. Chain link fencing other than for agricultural purposes shall be prohibited within PUDs; the use of split rail or other fencing made of natural materials is encouraged. 3. At preliminary plat, the Board found the applicant must include demarcation of the undisturbed buffer area, in the form of landscaping, fencing, or boulders, at the final plat stage of review. The applicant has provided a row of boulders spaced 25-ft on center with a #SD-22-07 Staff Comments 7 7 of 13 minimum dimension of 24-inches and a minimum above-ground height of 12-inches. They have also included a provision that a continuous split rail fence may be provided instead. Staff recommends the Board determine whether they consider the proposed boulders to be adequate. C. Agriculture. The conservation of existing agricultural production values is encouraged through development planning that supports agricultural uses (including but not limited to development plans that create contiguous areas of agricultural use), provides buffer areas between existing agricultural operations and new development, roads, and infrastructure, or creates new opportunities for agricultural use (on any soil group) such as but not limited to community- supported agriculture. The primary use of this property will remain agricultural. Staff considers this criterion met. D. Public Services and Facilities. In the absence of a specific finding by the Development Review Board that an alternative location and/or provision is approved for a specific development, the location of buildings, lots, streets and utilities shall conform with the location of planned public facilities as depicted on the Official Map, including but not limited to recreation paths, streets, park land, schools, and sewer and water facilities. (1) Sufficient water supply and wastewater disposal capacity shall be available to meet the needs of the project in conformance with applicable State and City requirement, as evidenced by a City water allocation, City wastewater allocation, and/or Vermont Water and Wastewater Permit from the Department of Environmental Conservation. The proposed development will be served by private water and wastewater systems. The applicant has indicated they are in the process of obtaining a state Wastewater and Potable Water Supply Permit. Staff recommends the Board require the applicant to demonstrate these permits have been obtained prior to issuance of the first zoning permit for the project. (2) Recreation paths, storm water facilities, sidewalks, landscaping, utility lines, and lighting shall be designed in a manner that is compatible with the extension of such services and infrastructure to adjacent properties. No additional development may take place on this parcel, as discussed under 9.12 above, therefore Staff considers this criterion to be not applicable. (3) Recreation paths, utilities, sidewalks, and lighting shall be designed in a manner that is consistent with City utility plans and maintenance standards, absent a specific agreement with the applicant related to maintenance that has been approved by the City Council. The applicant is proposing to serve three homes with a private access road. The applicant has indicated electric lines from Cheesefactory Road will serve the proposed homes, and will be located along the driveway serving those homes. (4) The plan shall be reviewed by the Fire Chief or his designee to insure that adequate fire protection can be provided, with the standards for evaluation including, but not limited to, minimum distance between structures, street width, vehicular access from two directions where possible, looping of water lines, water flow and pressure, and number and location of hydrants. The Fire Chief reviewed the plans on May 25, 2022 and confirmed that because the homes will be located greater than 150-feet from a public right of way, all homes must have a 13D compliant sprinkler system. The applicant is reminded the applicant will need a permit for the sprinkler from #SD-22-07 Staff Comments 8 8 of 13 the fire department. The Fire Chief recommends the applicant contact the fire department regarding the sprinkler system in order to ensure a cost-effective system is installed. Staff considers this criterion met. D. Circulation. The project shall incorporate access, circulation and traffic management strategies sufficient to prevent unsafe conditions on adjacent roads and sufficient to create connectivity for pedestrians, bicycles, vehicles, school transportation, and emergency service vehicles between neighborhoods. In making this finding the Development Review Board may rely on the findings of a traffic study submitted by the applicant, and the findings of any technical review by City staff or consultants. (1) Roads shall be designed in a manner that is compatible with the extension of such services and infrastructure to adjacent properties. The road is designed to meet City standards. (2) Roads shall be designed in a manner that is consistent with City roadway plans and maintenance standards, absent a specific agreement with the applicant related to maintenance that has been approved by the City Council. Staff considers this criterion met. (3) The provisions of Section 15.12(D)(4) related to connections between adjacent streets and neighborhoods shall apply. Staff considers the conservation easement precludes extension of the roadway to adjacent properties. 3.05B. Lots with No Road Frontage (2) The Development Review Board may approve subdivision or development of lots with no frontage on a public street, as long as access to such a street by a permanent easement or right-of-way at least twenty (20) feet in width is provided, according to the following procedures: (a) … (b) Conditions of Approval. Any application to create a new lot with no road frontage shall be subject to the requirements and major subdivision criteria of Article 15 of these Regulations in addition to this section. (i) Number of lots and/or dwelling units on a private right-of-way. The Development Review Board shall limit the number of developable lots on a private right-of-way to three (3) and/or the number of multi-family units to ten (10), whichever is less, beyond which a public street shall be required (See Article 15, Subdivision). The Development Review Board shall require a public street if the number of developable lots is greater than three (3) and/or the number of multi-family units is ten (10) or more, whichever is less. The Development Review Board may also limit the length of a private right-of-way, and may impose other conditions as may be necessary to assure adequate emergency access to all lots and dwelling units. (ii) The Development Review Board may require a right-of way wider than the twenty (20) foot minimum if it is to serve more than one (1) lot. (iii) The Development Review Board may impose conditions to insure the #SD-22-07 Staff Comments 9 9 of 13 maintenance and permanency of a private right-of-way and to insure that a right-of-way will not place a burden on municipal services. Staff considers these criteria met for the private road serving the three homes. 15.12 Standards for Roadways, Parking and Circulation D. Criteria for Public and Private Roadways (3) Private Roadways allowed. The DRB may at its discretion approve a roadway or roadways within a subdivision or PUD to be private if one or more of the following situations applies: (a) (b) not applicable (c) The proposed roadway serves five (5) or fewer single-family or duplex dwellings, an any combination of the two types of dwellings. Staff considers this criterion met. (4) Connections to adjacent parcels (a) if the DRB finds that a roadway or recreation path extension or connection to an adjacent property may or could occur in the future, whether through City action or development of an adjacent parcel, the DRB shall require the applicant to construct the roadway to the property line or contribute the cost of completing the roadway connection. Staff considers 9.12 and the conservation easement prohibit additional development on the parcel, therefore no connection may occur. E. Standards for Construction of Roadways (1) all streets shall be constructed completely by the applicant. (2) N/A (3) All private roadways shall be built to the specifications set forth in this section with the exception of curbing and widths. All private roadways shall be a minimum width of twenty-six (26) feet with parking and twenty (20) feet without parking. Table 15-1 specifies a road width of 20 ft for private roads without parking. Figure 15-1B specifies a specific roadway cross section. Section 15.12, discussed above, also requires private roads to be a minimum of 20-feet wide. The Land Development Regulations contemplate an 18-foot width for wetland crossings in certain sub-districts of the Southeast Quadrant. The NRP district is not one of those districts, because no new roads were contemplated at the time the regulations were developed. Because the wetland crossing is very near to the access point on Cheesefactory Road, a narrower width could create difficulty in making the turn and would result in an insignificant reduction in wetland buffer impacts. The Board at preliminary plat found the road width acceptable and found this criterion met. No changes to the road are proposed. #SD-22-07 Staff Comments 10 10 of 13 9.07 SOUTHEAST QUADRANT REGULATING PLANS A. N/A B. General Provisions (1) N/A (2) All residential lots created on or after the effective date of this bylaw in any SEQ sub-district shall confirm to a standard minimum lot width to depth ratio of one to two (1:2), with ratios of 1:2.5 to 1:5 recommended At preliminary plat, the lots did not meet the required minimum lot ratio. The Board allowed the proposed ratio since the objective of this standard is to create a neighborhood feel with homes close together and the applicant achieved this objective through other means. In addition, at preliminary plat, the conservation lot was included with one of the house lots. The applicant has modified lots 2 and 3 such that they now provide nearer to 1:2, while Lot 4 has a lot ratio of 1:0.62 due to the irregular shape to encompass the wastewater system. Proposed lots 2 and 3 have a width to depth ratio of 1:1.76. Staff recommends the Board allow the lots as designed. C. – D. N/A B) DIMENSIONAL REQUIREMENTS The Project is located in the Southeast Quadrant - Natural Resource Protection (SEQ-NRP) district. Dimensional standards are as follows. SEQ-NRP Required Proposed Lot 1 Proposed Lot 2 Proposed Lot 3 Proposed Lot 4 Min. Lot Size 12,000 sf 2,845,173 30,032 30,032 39,632 Max. Building Coverage 15% 0% 5.8% 5.8% 4.5% Max.

Front setbacks for lots 2 and 3 are measured to the private road. 4. The applicant has shown a building envelope on the plans to facilitate flexibility in locating the homes other than in the location shown on the plans. The Board at preliminary plat found the homes may be located anywhere within the building envelope. With the revised lot configuration, the applicant has proposed to increase the size of the building envelope for Lot 2 compared to the size of the building envelopes on Lots 3 and 4. Staff recommends the Board ask the applicant why they have proposed a larger building envelope for Lot 2, and discuss whether it should be reduced to better support the environmental protection goals of the zoning district. Staff notes the regulations do not require a building envelope but without one the applicant must construct the homes as shown on the plans. 5. Staff recommends the Board include a condition that overall coverage for each building lots (Lots 2, 3, and 4) shall not exceed 30% and building coverage not exceed 15%. Staff recommends the Board discuss an acceptable analogous maximum for the conservation lot, Lot 1. #SD-22-07 Staff Comments 11 11 of 13 C) SUBDIVISION STANDARDS All subdivisions for more than a single or two family residence in the SEQ district are required to be a PUD. As a PUD, the applicant is requesting certain waivers, discussed under SEQ standards above. (1) Sufficient water supply and wastewater disposal capacity is available to meet the needs of the project in conformance with applicable State and City requirements, as evidenced by a City water allocation, City wastewater allocation, and/or Vermont Water and Wastewater Permit from the Department of Environmental Conservation. The proposed development will be served by private water and wastewater systems. Staff considers this criterion met. (2) Sufficient grading and erosion controls will be utilized during construction and after construction to prevent soil erosion and runoff from creating unhealthy or dangerous conditions on the subject property and adjacent properties. In making this finding, the DRB may rely on evidence that the project will be covered under the General Permit for Construction issued by the Vermont Department of Environmental Conservation. See discussion under 9.06B(4) above. (3) The project incorporates access, circulation and traffic management strategies sufficient to prevent unreasonable congestion of adjacent roads. In making this finding the DRB may rely on the findings of a traffic study submitted by the applicant, and the findings of any technical review by City staff or consultants. This criterion differs slightly from the SEQ criterion pertaining to circulation in that it specifically addresses congestion. Staff considers the proposed development of three residential units served by a single curb cut will have no adverse impact on congestion of adjacent roads. (4) The project’s design respects and will provide suitable protection to wetlands, streams, wildlife habitat as identified in the Open Space Strategy, and any unique natural features on the site. In making this finding the DRB shall utilize the provisions of Article 12 of these Regulations related to wetlands and stream buffers, and may seek comment from the Natural Resources Committee with respect to the project’s impact on natural resources. See discussion above under 9.06B(1) Open Space Protection. (5) The project is designed to be visually compatible with the planned development patterns in the area, as specified in the Comprehensive Plan and the purpose of the zoning district(s) in which it is located. For Transect Zone subdivisions, this standard shall apply only to the location of lot lines, streets and street types, and natural resources identified in Article XII of these Regulations. Staff considers the proposed development visually compatible with the low density development patterns identified for the Natural Resource Protection district. (6) Open space areas on the site have been located in such a way as to maximize opportunities for creating contiguous open spaces between adjoining parcels and/or stream buffer areas. This criterion is discussed under 9.06B above. (7) The layout of a subdivision or PUD has been reviewed by the Fire Chief or his designee to insure that adequate fire protection can be provided, with the standards for approval including, but not be limited to, minimum distance between structures, street width, vehicular access from two directions where possible, looping of water lines, water flow and pressure, and number and location of #SD-22-07 Staff Comments 12 12 of 13 hydrants. All aspects of fire protection systems shall be designed and installed in accordance with applicable codes in all areas served by municipal water. This standard shall not apply to Transect Zone subdivisions. See discussion under 9.06D(4) above. (8) Roads, recreation paths, stormwater facilities, sidewalks, landscaping, utility lines and lighting have been designed in a manner that is compatible with the extension of such services and infrastructure to adjacent properties. For Transect Zone subdivisions, this standard shall only apply to the location and type of roads, recreation paths, and sidewalks. (9) Roads, utilities, sidewalks, recreation paths, and lighting are designed in a manner that is consistent with City utility and roadway plans and maintenance standards, absent a specific agreement with the applicant related to maintenance that has been approved by the City Council. For Transect Zone subdivisions, this standard shall only apply to the location and type of roads, recreation paths, and sidewalks. See discussion under 9.06D(3) above. (10) The project is consistent with the goals and objectives of the municipal Plan for the affected district(s). The Project is located in the area identified in the 2016 Comprehensive Plan as subject to Objective #60 and Strategies #135 and #137, as follow. Objective 60: Give priority to the conservation of contiguous and interconnected open space areas within this quadrant outside of those areas [districts, zones] specifically designated for development. Strategy 135: Continue to work with Shelburne on strategies to create a conserved agricultural and natural area, with appropriate public access and paths, from Shelburne Pond and Pond Road north to the Cider Mill development, consistent with the goals of the Open Space Strategy. Strategy 137: Through the development review process, land conservation initiatives, and development of Zoning Map amendments for the SEQ, work towards the addition of supplemental conserved areas adjacent and connected to existing open space lands. See discussion of conservation plan under SEQ-NRP supplemental regulations above. Staff considers this criterion met. (11) The project’s design incorporates strategies that minimize site disturbance and integrate structures, landscaping, natural hydrologic functions, and other techniques to generate less runoff from developed land and to infiltrate rainfall into underlying soils and groundwater as close as possible to where it hits the ground. For Transect Zone subdivisions, this standard shall apply only to the location of natural resources identified in Article XII of these Regulations. Staff considers the low density of the proposed development adequately protective of natural features. The total impervious proposed does not exceed the half-acre threshold for requiring compliance with Section 12 standards pertaining to stormwater. The applicant has provided two stormwater conveyance systems to convey runoff from the private road. One consists of a 15-inch pipe followed by 2 ft wide and 1 ft deep stone ditch, and the second consists of a 15-inch pipe with outfall protection. Staff considers this criterion met. #SD-22-07 Staff Comments 13 13 of 13 D) CONDITIONAL USE REVIEW Pursuant to Section 9.12B of the South Burlington Land Development Regulations (development of lots in SEQ-NRP district), the proposed use shall be reviewed as a conditional use and shall meet the following standards of Section 14.10(E): 14.10E General Review Standards The Development Review Board shall review the proposed conditional use for compliance with all applicable standards as contained in these regulations. The proposed conditional use shall not result in an undue adverse effect on any of the following: (1) The capacity of existing or planned community facilities. This project will have no adverse effect upon community facilities. Staff considers this criterion met. (2) The character of the area affected, as defined by the purpose or purposes of the zoning district within which the project is located, and specifically stated policies and standards of the municipal plan. The purpose of the zoning district is, in part, to encourage open space preservation, and well-planned residential use. Staff considers this criterion met. (3) Traffic on roads and highways in the vicinity. Staff considers this project will have no adverse effect on traffic on roads and highways in the vicinity. Staff considers this criterion met. (4) Bylaws and ordinances then in effect. Staff considers this criterion will be addressed when other comments in this document are addressed. (5) Utilization of renewable energy resources. This project will not affect renewable energy resources. Staff considers this criterion met.

April 7, 2022 Marla Keene, PE Development Review Planner Planning & Zoning Office City of South Burlington 180 Market Street South Burlington, VT 05403 RE: Hickory Hillside – Residential Planned Unit Development 47 Cheesefactory Road, South Burlington Final Subdivision Plat Dear Marla: We are writing on behalf of Hickory Hillside, LLC. to request Final Subdivision Plat review for the project known as Hickory Hillside Residential PUD (#SD-21-22), located at 47 Cheesefactory Road. This project was reviewed with the DRB as a Sketch Plan on 4/6/2021 and again on 9/8/2021 under Preliminary Subdivision Plat. Since the Preliminary Subdivision Plat review in September, the following items and modifications to the project/plans have taken place:  Murray & Masterson Environmental Services has finalized the design of the wastewater disposal system for each lot and is in the process of obtaining a state Wastewater and Potable Water Supply Permit.  We have revised the lot depths to meet, or more closely meet, the recommended ratios in Article 9.07.B(2).  We are requesting approval to create an additional lot, however, there is no change to the general concept of the project. Rather than Lot 1 containing both a portion of the farm complex and the remaining conservation land, this application will have all of Lot 1 remain in agricultural/conservation and Lots 2-4 make up the farmstead complex as identified in the Conservation Restrictions document.  Minor adjustment to tree locations due to the revised wastewater disposal area locations.  Addition of wetland demarcation boulders along the City wetland buffer. Project Narrative This project includes the subdivision of an existing 67.6-acre parcel at the southwest corner of Hinesburg Road (VT Route 116) and Cheesefactory Road. The parcel is bounded by Muddy Brook along a portion of the southern property limits. The majority of the parcel is used for agricultural crop rotation and rotational livestock grazing. The project is located entirely in the Southeast Quadrant Natural Resource Protection District (SEQ- NRP). There is a portion of the project along Muddy Brook which is located within the Flood Plain Overlay District; however, no work is proposed within this overlay district. This project proposes to subdivide the existing parcel into three residential lots (Lots 2-4) and one lot to be covered by conservation restrictions (Lot 1) in accordance with Article 9.12.B(2)(f). The proposed Lamoureux & Dickinson Page 2 Consulting Engineers, Inc. parcel areas for Lots 1-4 are 65.31 acres, 0.69 acres, 0.69 acres, and 0.91 acres, respectively. “Sheet 2 – Site, Grading, Landscaping and EP&SC Plan” includes a dimensional table detailing the required and proposed standards of each lot. It is the intent of the applicant to promote the continued agricultural uses on the project parcel, while being able to extend this opportunity to possible future farmers and homeowners on the project parcel. The applicant represents the farmers who will likely seek to develop Lot 2 and continue the agricultural uses on the conservation lands (Lot 1). Due to the uncertainty of the timing for development on Lots 3 & 4 the applicant is requesting that the construction of the private road not be required until the second lot (either Lot 3 or Lot 4) is developed. This allows flexibility in the development and timing of the lots, and eliminates the heavy burden that would be placed on Lot 2 to construct and maintain substantial infrastructure that would only be needed for the development of multiple lots. This project continues to request the following waiver, which was previously granted in the Preliminary Plat approval in 2020 and again in the Preliminary Plat approval in 2021:  Waiver from Article 9.12.B(2)(d) to allow homes to be placed more than 100 feet from each other, within the building envelopes shown.  Wavier from Article 9.07.B(2) to allow Lot 4 to have a width to depth ratio of 1:0.62 due to its irregular shaped to encompass the wastewater system. The following items are enclosed for your review:  Application for Final Subdivision Plat  $663.00 application fee ($500 + $25 X 2 lots + $50 X 2 lots + $13 recording)  Abutters list  Cost estimate for landscaping (revised June 2021)  Updated Wetland Memorandum by Joe Bartlett of Fitzgerald Environmental Associates (revised June 2021)  Wetland correspondence between FEA & VTANR Wetlands Program (Tina Heath)  Conservation Map (Exhibit A) – no change from previous submission  Draft Conservation Management Plan (Exhibit B) – no change from previous submission  Ecological Protection Zone, Riparian Buffer Zone, & Public Access Easement (Exhibit C) – no change from previous submission  Draft Shared Road Maintenance Agreement & Stormwater Maintenance Agreement (revised March 2022)  House Likeness Elevations – no change from previous submission  Plan Set by Lamoureux & Dickinson: o Sheet 1 – Overall Site Plan (last revision date 4/7/2022) o Sheet 2 – Site, Grading, Landscaping and EP&SC Plan (last revision date 4/7/2022) o Sheet 3 – Sitework Details & Specifications (last revision date 3/7/2022) o Sheet 4 – Erosion Prevention and Sediment Control Details & Specifications o Sheet PL – 4-Lot Planned Unit Development Plat (last revision date 4/7/2022) Please contact our office with any questions.
