Upcoming meeting schedule 8. Adjourn (8:30 pm) Respectfully submitted, Paul Conner, AICP, Director of Planning & Zoning * item has attachments South Burlington Planning Commission Virtual Meeting Public Participation Guidelines 1. The Planning Commission Chair presents these guidelines for the public attending Planning Commission meetings to ensure that everyone has a chance to speak and that meetings proceed smoothly. 2. In general, keep your video off and microphone on mute. Commission members, staff, and visitors currently presenting / commenting will have their video on. 3. Initial discussion on an agenda item will generally be conducted by the Commission. As this is our opportunity to engage with the subject, we would like to hear from all commissioners first. After the Commission has discussed an item, the Chair will ask for public comment. 4. Please raise your hand identify yourself to be recognized to speak and the Chair will try to call on each participant in sequence. To identify yourself, turn on your video and raise your hand, if participating by phone you may unmute yourself and verbally state your interest in commenting, or type a message in the chat. 5. Once recognized by the Chair, please identify yourself to the Commission. 6. If the Commission suggests time limits, please respect them. Time limits will be used when they can aid in making sure everyone is heard and sufficient time is available for Commission to to complete the agenda. 7. Please address the Chair. Please do not address other participants or staff or presenters and please do not interrupt others when they are speaking. 8. Make every effort not to repeat the points made by others. You may indicate that you support a similar viewpoint. Indications of support are most efficiently added to the chat. 9. The Chair will make reasonable efforts to allow all participants who are interested in speaking to speak once to allow other participants to address the Commission before addressing the Commission for a second time. 10. The Planning Commission desires to be as open and informal as possible within the construct that the Planning Commission meeting is an opportunity for commissioners to discuss, debate and decide upon policy matters. Regular Planning Commission meetings are not “town meetings”. A warned public hearing is a fuller opportunity to explore an issue, provide input and influence public opinion on the matter. 11. Comments may be submitted before, during or after the meeting to the Planning and Zoning Department. All written comments will be circulated to the Planning Commission and kept as part of the City Planner's official records of meetings. Comments must include your first and last name and a contact (e-mail, phone, address) to be included in the record. Email submissions are most efficient and should be addressed to the Director of Planning and Zoning at pconner@sburl.com and Chair at jlouisos@sburl.com. 12. The Chat message feature is new to the virtual meeting platform. The chat should only be used for items specifically related to the agenda item under discussion. The chat should not be used to private message Commissioners or staff on policy items, as this pulls people away from the main conversation underway. Messages on technical issues are welcome at any time. The Vice-Chair will monitor the chat and bring to the attention of Commissioners comments or questions relevant to the discussion. Chat messages will be part of the official meeting minutes. 13. In general discussions will follow the order presented in the agenda or as modified by the Commission. 14. The Chair, with assistance from staff, will give verbal cues as to where in the packet the discussion is currently focused to help guide participants. 15. The Commission will try to keep items within the suggested timing published on the agenda, although published timing is a guideline only. The Commission will make an effort to identify partway through a meeting if agenda items scheduled later in the meeting are likely not be covered and communicate with meeting participants any expected change in the extent of the agenda. There are times when meeting agendas include items at the end that will be covered “if time allows”. 575 Dorset Street South Burlington, VT 05403 tel 802.846.4106 fax 802.846.4101 www.sburl.com MEMORANDUM TO: South Burlington Planning Commission FROM: Paul Conner, Director of Planning & Zoning SUBJECT: Planning Commission Meeting Memo DATE: March 31, 2021 Planning Commission meeting 1.

Adjourn (8:30 pm) 575 Dorset Street South Burlington, VT 05403 tel 802.846.4106 fax 802.846.4101 www.sburl.com MEMORANDUM TO: South Burlington Planning Commission FROM: Paul Conner, Director of Planning & Zoning SUBJECT: Draft Environmental Protection Standards & Related Amendments, LDR-20-01 DATE: March 31, 2021 Planning Commission meeting Enclosed please find the following documents: • Draft Environmental Protection Standards & Related Amendments (LDR-20-01) [Clean Version] • Draft Natural Resources Map • Draft Planning Commission Report A Red-Line version of the Draft Amendments is posted to the City’s website. Edits from prior version: The draft amendments are substantially the same as the draft your received last week. Staff made the following minor edits based on your discussion: 1. Corrected definitions to reference “Habitat Blocks” and “Habitat Connectors” rather than “Forest Blocks” and “Forest Connectors” 2. Added the following language to the definition of a Habitat Block: “Habitat Blocks at time of establishment in these Regulations are greater than 50% forested and totals at least 20 acres in size (area may, however, extend beyond City boundary). Portions of contiguous forest or shrubland that cannot be connected by an area wider than 160’ are not considered habitat blocks.” 3. Standardized use of “Level I” and “Level II” – prior drafts sometimes had “Level 1” and “Level 2” 4. Within Section 12.03 (wetlands) added minor clarifying language regarding the statement that impacts are “generally prohibited” by specifically referencing the sections below that allow for limited impacts 5. Within Section 12.03 (wetlands) made clear that the instances where a modification are permissible are the only instances where such modifications are permissible 6. Reviewed the text to make sure that “waivers” only refer to actual waiver of requirements (submission requirements, for instance, and demarcation of resource boundaries by fences IF the DRB finds that there is sufficient existing demarcation, and using the term “modification” where the DRB has (limited) authority to modify the extent of a rule 7. Added language regarding fencing adjacent to natural resources that it must allow for passage of wildlife 2 Draft Planning Commission Report Also enclosed with your packet is a draft Report, as required by State Law, to accompany the proposed amendments. The Report is required to provide a brief summary and to make findings on three specific topics, as included. Typically, the Report contains a very brief (1-2 paragraph) summary of the amendments. In this case, due to the nature of the amendments, staff has proposed more complete summary for the public to be able to a more full picture without having to read the full text. The Commission is welcome to add to, remove, or otherwise modify the Report. Remaining Subject: Southeast Quadrant Natural Resource Protection (SEQ-NRP) Boundary Staff was asked at the last meeting to evaluate the implications of either including the adjustments to the SEQ-NRP boundary as discussed in October 2020 now, or saving them for the next round of amendments that are planned to include other zoning district changes, PUD, Subdivision, Master Plan, and the other related amendments. Below is a map showing highlighting the changes discussed in October. • Green shows the Existing SEQ-NRP Boundary • Purple shows the SEQ-NRP Boundary as discussed in October 2020 • Blue are the Habitat Blocks and Habitat Connectors Staff Analysis – SEQ-NRP 3 Virtually all of the proposed areas to be added to the SEQ-NRP are contained within a Habitat Block. The only exception to this is in South Village, where modifications to the SEQ-NRP were intended to align with the approved Master Plan. Considerations / Implications: • Land within the SEQ-NRP must be excluded from a Planned Unit Development. And land within the SEQ- NRP does not count towards the minimum 70% open space within a Conservation PUD, and must be excluded from a traditional neighborhood development altogether. • Land within the SEQ-NRP cannot be part of any Habitat Block “exchange.” And so, while Section 12.06 allows for limited exchanges of Habitat Block land through one of three options (50’ in any direction to account for the nature of the mapping; up to 2 acres exchanged to allow for a disconnected tree stand elsewhere to be protected instead; or larger subject to a Habitat and Disturbance Assessment), these options are NOT available for any Habitat Block within the SEQ-NRP. • When the Commission reviewed the habitat block boundaries in October, the discussion began by reviewing certain areas in the SEQ and then aligning the SEQ-NRP and the Habitat Block. Later in the same meeting, after reviewing other parts of the City, the Commission returned to a few other parts of the SEQ. In those later discussions, the Commission elected to keep the zoning di strict boundaries where they were and instead apply only the new Habitat Blocks. The Commission did not circle back to the earlier part of the meeting to affirm the approach to take. • In the intervening time since the October review, it has come to staff’s attention that the current Regulations’ requirement that maximum lot coverage be met by zoning district may have implications on existing neighborhoods in the SEQ. In the instance of South Village, the property owners recently went before the DRB to update their plans to include remaining phases and the proposed commercial building. When South Village was originally approved, it was all within a single zoning district. More recently, a substantial portion of the projects is in the SEQ-NRP. Lot coverage was just met as a result. The addition of land to the SEQ-NRP as proposed may have impacts that have not been evaluated. Staff recommends that the Commission review this information prior to making a determination of whether to include the possible changes to the SEQ-NRP at this time or to consider them as part of the full LDR update package. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 1 LDR-20-01: ENVIRONMENTAL PROTECTION STANDARDS & RELATED KEY TO AMENDMENTS: Text in yellow highlights are notes to the draft ARTICLE 2 DEFINITIONS [NOTE TO DRAFT: ONLY TEXT WITH CHANGES TO SECTION 2.01 ARE DISPLAYED]. … 2.02 Specific Definitions … Building Envelope. A designated area or portion of a lot, delineated on a subdivision plat, within which all structures, parking and loading areas, and clearing of land must be located, with the exception of driveways and utility lines. A building envelope shall be defined by minimum setback and maximum height requirements unless otherwise specified in these Regulations. Environmental Restoration Project: A project authorized under the MS4 General Permit, TS4 General Permit, or Municipal Roads General Permit (MRGP), that address a primary pollution source identified in a Vermont Department of Environmental Conservation approved watershed implementation plan (i.e. TMDL, Flow Restoration Plan, or Phosphorus Control Plan) and is not required for the purpose of developing or redeveloping impervious surfaces. Additionally, any floodplain reconnection or stream channel restoration projects that are not included in a Flow Restoration Plan or Phosphorus Control Plan, but are necessary to meet the required pollutant reductions in a TMDL. Habitat Block. Contiguous forested and adjacent unmanaged shrubby areas of old field, young forest, and unmanaged wetland as demarked on the Natural Resources Map. Includes areas large enough to provide habitat, either permanently, or seasonally for wider ranging species of wildlife such as bobcat, red and grey fox, white-tailed deer, river otter and fisher. These species of wildlife require larger areas (than squirrels or rabbits for example), and a variety of appropriate habitat to fulfill their daily, seasonal, and yearly habitat needs. These needs include security for breeding activities, a variety of food resources, secure cover for raising young, and the presence of water- either for drinking or in the case of aquatic species, as a general habitat. Habitat Blocks fall within a matrix of land-uses that include urban, residential, agricultural, transportation, and rural uses. Habitat Blocks at time of establishment in these Regulations are greater than 50% forested and totals at least 20 acres in size (area may, however, extend beyond City boundary). Portions of contiguous forest or shrubland that cannot be connected by an area wider than 160’ are not considered habitat blocks. Habitat Connector. Areas in the providing wildlife served by Habitat Blocks the ability to move across the landscape in stepping-stone fashion between Habitat Blocks as demarked on the Natural Resources Map. For species such as fox, fisher, and bobcat, accessing multiple Habitat Blocks make up for the smaller, more fragmented nature of the Habitat Blocks in the community. Hazard: Floodplain overlay districts A, AE, A1-30, and 0.2% B2, River Corridors except those along intermittent streams, Very Steep Slopes, Class 1 and Class 2 wetland and associated buffers Level I Resources: A Habitat Block or Habitat Connector. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 2 Level II Resources: River Corridors along intermittent streams, Floodplain Overlay District Zone 0.2% B1 (500- year floodplain, Class 3 wetlands (greater than 300 square feet in size) and associated buffers, and steep slopes. Rare, Threatened or Endangered Species. A wildlife or plant species identified by the Vermont Department of Fish & Wildlife as being rare, threatened or endangered. Significant Wildlife Habitat. Those natural features that contribute to the survival and/ or reproduction of the native wildlife of South Burlington. This includes: (1) habitat for rare, threatened and endangered species (state or federally listed); (2) River Corridors as defined in these regulations; (3) wetlands and wetland buffers as defined in these Regulations; (4) Habitat Blocks, and (5) Habitat Connectors. Site Balancing. Where stormwater control and/or treatment of certain limited areas of new, redeveloped, or substantially reconstructed impervious surface area are not possible, the impact from these areas of untreated impervious surfaces will be compensated on an equivalent basis by controlling and/or treating other impervious surfaces on the lot, parcel, or property. This can be accomplished by providing additional control and/or treatment beyond what is required for impervious surface areas already subject to the requirements of 12.08(C) or by providing control and/or treatment for impervious surfaces that are not otherwise required to meet the requirements of 12.08(C). The applicant must own or otherwise control the impervious surfaces used for site balancing. Steep Slopes. Any land formation, aside from individual rocks, with a measured slope of between 15 and 25% containing a vertical drop of at least three (3) feet. Steep Slopes, Very. Any land formation, aside from individual rocks, with a calculated slope of over 25% containing a vertical drop of at least three (3) feet. Stream. A watercourse having a source and terminus, banks, and channel through which waters flow at least periodically. Stream, intermittent. Streams with a drainage area smaller than .5 square miles that are not subject to the River Corridor regulations. This definition shall not include ditches and other constructed channels primarily associated with land drainage or water conveyance. Substantial reconstruction. The reconstruction of an impervious surface where an impervious surfac e currently exists when such reconstruction involves site grading, subsurface excavation, or modification of existing stormwater conveyance. Substantial reconstruction does not include maintenance or management activities on impervious surfaces including any crack sealing, patching, cold planning, resurfacing, or reclaiming treatments used to maintain pavement and bridges, or grading treatments used to maintain unpaved roads. Undue Adverse Effect. An impact that 1) violates a clear, written community standard under these regulations, and that 2) cannot be mitigated through siting or design modifications or conditions of approval. Wetland. An area that is inundated by surface or groundwater with a frequency sufficient to support vegetation or aquatic life that depend on saturated or seasonally saturated soil conditions for growth and reproduction. Such areas include, but are not limited to, fens, marshes, swamps, sloughs, potholes, ponds, but excluding such areas as grow food or crops in connection with farming activities. The boundary of a wetland shall be delineated by the methodology set forth in the 1989 edition of the Federal Manual for Identifying and Delineating Jurisdictional Wetlands, or any subsequent amendment or revision of that document. Wetlan ds are classified as Class I, Class II, or Class III wetlands by the most recently adopted Vermont Wetland Rules.

Average grade level. The average of the natural or exiting topography at center of all exterior walls of a building or structure to be placed on site. Substantial damage. In Floodplain Overlay District Zones A, AE, and A1-30, damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged conditions would equal or exceed 50 percent of the market value of the structure before the damage occurred. In Floodplain Overlay District Zones 0.2% B1 and B2, damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged conditions would equal or exceed 75 percent of the market value of the structure before the damage occurred. Substantial improvement. In Floodplain Overlay District Zones A, AE, and A1-30, any repair, reconstruction, rehabilitation, addition, or other improvement of a structure after the date of adoption of this bylaw, the cost of which, over three years, or over the period of a common plan of development, cumulatively equals or exceeds 50 percent of the market value of the structure before the “start of construction” of the improvement. In Floodplain Overlay District Zones 0.2% B1 and B2, any repair, reconstruction, rehabilitation, addition, or other improvement of a structure after the date of adoption of this bylaw, the cost of which, over three years, or over the period of a common plan of development, cumulatively equals or exceeds 75 percent of the market value of the structure before the “start of construction” of the improvement. This term includes structures which have incurred “substantial damage”, regardless of the actual repair work performed. The term does not, however, include either: (a) Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been previously identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions or (b) Any alteration of an “historic structure”, provided that the alteration will not preclude the structure’s continued designation as an “historic structure”.

Chapter 32 § 753, which are hereby adopted by reference and declared to be part of these regulations. Zone 0.2% has been further divided into Zone B1 and Zone B2 on Map ****, and Map *** is hereby incorporated into these Regulations .The location of the boundary shall be determined by the Administrative Officer (AO). (a) Floodplain Overlay District Zones A, AE, and A1-30. The boundaries of these Zones include those areas of special flood hazard designated in and on the above referenced studies and maps as Zones A, AE, or A1-30. (b) Floodplain Overlay District Zones 0.2% B1 and B2. The boundaries of these Zones include those areas of special flood hazard designated in and on the above referenced studies and maps as Zone 0.2%, and are separated into a zone that reflects generally developed and priority development areas, and a zone that reflects generally undeveloped areas. 3.02 Official Maps and Other Maps … D. Natural Resources Map. The Natural Resources map identifies Hazards, Level I Resources and Level II Resources that are subject to the restrictions set forth in Articles 10 and 12 of these 3.03 District Boundaries … 3.04 Applicability of Regulations … H. Undue Adverse Effect. Where the terms Undue Adverse Effect or Undue Adverse Impact are used in these Regulations, the Development Review Board shall apply the test enumerated in Figure 3-0, Determining Undue Adverse Effect LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 5 Figure 3-0 Determining Undue Adverse Effect The following test shall be used by the Development Review Board in all circumstances when the South Burlington Land Development Regulations requires the Development Review Board to determine whether or not an undue adverse effect is being created. 1. First, the Development Review Board shall determine if a proposed project will have an adverse effect upon the resource, issue and/or facility in question. The Development Review Board shall determine such by responding to the following question: (a) Will the project have an unfavorable impact upon the resource, issue and/or facility in question? 2. If it is determined by the Development Review Board that an adverse effect will be being created by a project, the Development Review Board shall then determine if the adverse effect is “undue.” To determine whether or not an adverse effect is undue, the Development Review Board shall respond to the following two questions: (a) Will the project conflict with a clear, written standard in these regulations or the Municipal Plan applicable to the resource, issue or facility in question? (b) Can the unfavorable impact be avoided through site or design modifications, or mitigation, or other conditions of approval? The Development Review Board shall conclude that adverse effect is “undue” if the answer to 2(a) is YES OR the answer to 2(b) is NO. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 6 ARTICLE 9 SOUTHEAST QUADRANT – SEQ [NOTE TO DRAFT: ONLY TEXT WITH CHANGES WITHIN ARTICLE 9 ARE DISPLAYED]. 9.06 Dimensional and Design Requirements Applicable to All Sub-Districts … 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 creating usable, contiguous open spaces between adjoining parcels, creating or enhancing stream buffer areas, or creating or enhancing buffers for primary or secondary natural communities. (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. (3) A plan for the proposed open spaces and/or natural areas and their ongoing management shall be established by the applicant. Such plan shall describe the intended use and maintenance of each area. Continuance of agricultural uses or enhancement of wildlife habitat values in such plans for use and maintenance is encouraged. Existing natural resources on each site shall be protected through the development planIn making this finding the Development Review Board shall use the provisions of Articles 10 and 12 of this bylaw related to Hazards, Level I Resources, and Level II Resources. (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 condit ions 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. 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. Provisions that enhance overall neighborhood and natural resource values rather than preservation of specific soil types are strongly encouraged. 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. (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: LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 7 (a) Driveways, roads, underground utility services, or other appurtenant improvements to serve approved development or uses.

Avoid and minimize the loss of life and property, the disruption of commerce, the impairment of the tax base, and the extraordinary public expenditures and demands on public services that result fro m flooding; 2. Ensure that the selection, design, creation, and use of development is reasonably safe and accomplished in a manner that is consistent with public wellbeing, does not impair flood plain services or the stream corridor; 3. Manage the flood hazard area designated pursuant to 10 V.S.A. Chapter 32 § 753, the municipal hazard mitigation plan; and make the City of South Burlington, its citizens, and businesses eligible for federal flood insurance, federal disaster recovery funds, and hazard mitigation funds as may be available. B. Authority. In accordance with 10 V.S.A. Chapter 32, and 24 V.S.A. Chapter 117 §4424, §4411 and §4414, there is hereby established a bylaw for areas at risk of flood damage in the City of South Burlington Vermont. These regulations shall apply to development in all areas in the City of South Burlington identified as within the Floodplain Overlay District designated in Section 3.01(B). C. [reserved] D. Administration 1. Floodplain Review. All development in the City of South Burlington located within the Floodplain Overlay District shall be subject to Floodplain Review. The Floodplain Overlay District overlays other existing zoning districts. All other requirements of the underlying district shall apply in addition to the provisions herein, unless otherwise indicated. The Floodplain Overlay District is composed of two areas: a. Floodplain Overlay District Zones A, AE, and A1-30. The boundaries of these Zones include those areas of special flood hazard designated in and on the most current flood insurance studies and maps published by the Department of Homeland Security, Federal Emergency Management Agency, National Flood Insurance Program and mapped as Zones A, AE, or A1- 30. b. Floodplain Overlay District Zones 0.2% B1 and B2. The boundaries of these Zones include those areas of special flood hazard designated in and on the most current flood insurance studies and maps published by the Department of Homeland Security, Federal Emergency Management Agency, National Flood Insurance Program, and on Map ****, and Map ***, and mapped as Zone 0.2% B1 and Zone 0.2% B2. Floodplain Overlay District Zone 0.2% B1 is composed of areas of the 500-year floodplain that are already substantially developed and where additional opportunities for infill development is appropriate. Floodplain Overlay District Zone 0.2% B2 is composed of areas of the 500-year floodplain that are not developed and where future development is not appropriate. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 10 2. Interpretation. The information presented on any maps, or contained in any studies, adopted by reference, is presumed accurate. However, if uncertainty exists regarding the Floodplain Overlay District boundary, the following procedure shall be followed: a. If uncertainty exists with respect to the boundaries of the Floodplain Overlay District Zones A, AE, and A1-30 the location of the boundary shall be determined by the Administrative Officer. If the applicant disagrees with the determination made by the Administrative Officer, a Letter of Map Amendment from FEMA shall constitute proof that the property is not located within the Special Flood Hazard Area. b. If uncertainty exists with respect to the boundaries of the Floodplain Overlay District Zones 0.2% B1 and B2 the location of the boundary shall be determined by the Administrative Officer. If the applicant disagrees with the determination made by the Administrative Officer, the applicant may appeal the determination in accordance with Article 17. 3. Base Flood Elevations and Floodway Limits. a. Where available (i.e. zones A1-A30, AE, AH, and 0.2% B1 within the floodplain of the Winooski River), the base flood elevations and floodway limits (or data from which a community can designate regulatory floodway limits) provided by the National Flood Insurance Program in the Flood Insurance Study and accompanying maps shall be used to administer and enforce the provisions of these regulations. b. In Zone A of the Floodplain Overlay District where base flood elevations and floodway limits have not been provided by the National Flood Insurance Program in the Flood Insurance Study and accompanying maps, it shall be the responsibility of the applicant to develop the base flood elevation at the site using data available from state or federal agencies or other sources. 4. Warning of Disclaimer of Liability. This bylaw does not imply that land outside of the areas covered by this overlay district will be free from flood damages. These regulations shall not create liability on the part of the City of South Burlington, or any municipal official or employee thereof, for any f lood damages that result from reliance on these regulations, or any administrative decision lawfully made hereunder. 5. Precedence of Bylaw. The provisions of this Floodplain Overlay District shall not in any way impair or remove the necessity of compliance with any other local, state, or federal laws or regulations. Where these regulations imposes a greater restriction the provisions here shall take precedence. 6. Exempted Development. The following types of development are exempt from Floodplain Review. The following types of development may also still be subject to other standards in the South Burlington Land Development Regulations including Section 12.01 General Stream and Surface Water Protection Standards: a. The removal of a building or other improvement in whole or in part, so long as the ground elevations under and adjacent to the removed structure remain unchanged. Please be aware that for damaged structures where FEMA mitigation funds may be used, the damaged structure may be required to remain in place until funds are granted. b. Routine maintenance of existing buildings in the usual course of business required or undertaken to conserve the original condition, while compensating for normal wear and tear. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 11 c. Routine maintenance includes actions necessary for retaining or restoring a piece of equipment, machine, or system to the specified operable condition to achieve its maximum useful life and does not include expansions or improvements to development. d. Interior improvements to existing buildings that cost less than five-hundred (500) dollars. e. Maintenance of existing sidewalks, roads, parking areas, or stormwater drainage; this does not include expansions. f. Maintenance of existing bridges, culverts, and channel stabilization activities; this does not include expansions. g. Streambank armoring and stabilization, retaining walls, and abutment work that do not reduce the cross-sectional flow area of the river or stream channel and have coverage under a Stream Alteration Permit, if required, under 10 V.S.A. Chapter 41 and the rules adopted thereunder. h. The following activities are exempt from Floodplain Review, but may require a permit under the State’s “Vermont Flood Hazard Area and River Corridor Rule” (Environmental Protection Rule, Chapter 29): i. State-owned and operated institutions and facilities. ii.

The information presented on any maps, or contained in any studies, adopted by reference, is presumed accurate. If uncertainty exists with respect to the boundaries of the RCO the location of the boundary on the property shall be determined by the LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 21 Administrative Officer (AO). If the applicant disagrees with the determination made by the AO or the river corridor as mapped, the applicant has the option to either: (a) Hire a licensed land surveyor or registered professional engineer to stake out the RCO boundary on the property; or (b) Request a letter of determination from ANR which shall constitute proof of the location of the river corridor boundary. In support of a letter of determination request, applicants must provide ANR a description of the physical characteristics that bring the river corridor delineation into question (e.g. the presence of bedrock or other features that may confine lateral river channel adjustment. When ANR receives a request for a letter of determination, ANR evaluates the site and existing data to see if a change to the river corridor delineation is justified, necessitating a river corridor map update. An ANR letter of determination will either confirm the existing river corridor delineation or will result in an update to the river corridor delineation for the area in question. If a map update is justified, an updated map will be provided with the letter of determination. G.

Where an applicant elects to perform a Habitat Disturbance Assessment, the submittal requirements of Section 12.07 shall apply. D. Modification of Habitat Block. An applicant may request approval from the Development Review Board to modify a mapped Habitat Block in any of the following manners. An applicant may select any one of the options three modification methods below. A development application may not include more than one option for any application. Land located within the SEQ-NRP zoning subdistrict, Hazards, Level I resources, previously approved as open space or conserved land, subject to a deed restriction prohibiting development, subject to a conservation or density reduction easement, or owned by a public entity shall not be eligible for any of the modification methods for habitat blocks subject to this section. (1) Minor Habitat Block Boundary Adjustment. An applicant may apply to modify the boundary of a mapped Habitat Block by up to fifty (50) feet in any direction to account for site-specific conditions, upon written request by the applicant as part of the requisite application. Any prop osed modification in Habitat Block area must be offset with an equal addition elsewhere within the same subject parcel or Planned Unit Development that is contiguous to the Habitat Block. In no case shall the Development Review Board approve a net reduction of a Habitat Block. (2) Small On-Site Habitat Block Exchange. An applicant may apply to exchange a mapped Habitat Block area not to exceed two (2) acres or ten (10) percent of the application’s total land area, whichever is less, for an equal amount of land within the same Planned Unit Development or Site Plan upon written request, without requiring a Habitat and Disturbance Assessment. Such land exchange must not include Core Habitat Areas and shall not eliminate existing Habitat Connectors. To approve a small on-site habitat block exchange, the Development Review Board shall require the applicant to: (a) Retain a similar or greater quality and maturity of vegetation within the proposed areas for exchange; and (b) Retain mature and/or prominent tree stands. (3) Larger Area Habitat Block Exchange.

The exchange of land w ithin the same Habitat Block may occur within one parcel or on separate parcels. (a) Supplemental submittal requirements. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 32 (i) Indicate, on the Master Plan and all subsequent plans, all proposed alterations to the Habitat Block. (ii) Submit, as part of the preliminary plat application, a Habitat and Disturbance Assessment (HDA) pursuant Section 12.07 and a written assessment of compliance with the standards contained within this subsection. (b) Supplemental Standards of Review. The Development Review Board may approve a re- designation of a portion of a Habitat Block if it finds all of the criteria below to be met: (i) The HDA demonstrates that the alteration will not result in a reduction in the Habitat Block’s function as a significant wildlife habitat as defined in these Regulations; (ii) Wildlife movement connectivity is retained between mapped Habitat Blocks; and, (iii) Proposed adjacent development and infrastructure must be designed to have no undue adverse effects on habitat functions. (c) Exchanged Land. Land to be added to the Habitat Block pursuant to this section must be set aside and identified on the subdivision plat, and in associated legal documents, as one or more “Conservation Lots” as established in Section 15A, 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, that is contiguous to the habitat block and unseparated by roadways, railways, or other impeding infrastructure. (i) Land located with the SEQ-NRP zoning subdistrict, Hazards, Level I resources, previously approved as open space or conserved land, subject to a deed restriction prohibiting development, subject to a conservation or density reduction easement, or owned by a public entity shall not be eligible to be used for a land exchange. (ii) Any land proposed to be added / conserved shall be accompanied by a restoration plan, prepared by a landscape architect, professional wildlife biologist, or equivalent, that will result in the land functioning as a significant wildlife habitat such that within a period of ten (10) years and being classified as transitional forest / forest by a land use / land cover assessment at that time. E. Substantially-Habitat Block-covered lots. A lot or parcel containing a combination of Hazards and Level I resources exceeding seventy (70) percent of the total lot area is eligible for relief from Habitat Block standards as follows: (1) [Reserved] (2) The Development Review Board may approve exclusion of an area of land within the Habitat Block not to exceed thirty (30) percent of the total lot area. Where applicable, land shall be excluded in the following order: • First: Land not a Hazard or Level I resources; • Second: Land that is not characterized by a preponderance of mature trees; • Third: Land within Habitat Blocks, excluding Core Habitat Block areas or which would sever a Habitat Connector. • Fourth: Land within Habitat Blocks, avoiding core habitat block areas to the greatest extent possible; LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 33 (a) Calculation: Land shall be selected from first to fourth If all applicable land on the lot or parcel from one category is excluded, and the thirty (30) percent allotment of excluded land has not been reached, then land from the next category land shall be selected next. (b) Special Circumstances: Where the DRB finds that exclusion of land pursuant to the priority order above is in conflict with the purposes of this section, or where it finds that strict adherence to the priority order does not allow for a unified PUD consistent with the purposes of intent of these regulations, it may approve modifications to the land selected. Any such modifications shall be minimized in terms of land area and modification to the priority order. (c) Any land excluded from Habitat Blocks regulated under this subsection shall remain subject to all other provisions of these Regulations. F. Standards for Habitat Block Protection.

Purpose. It is the purpose of this Section to maintain the functionality of identified Habitat Connectors, allowing species to travel between identified Habitat Blocks, wetland areas, water bodies, and other natural resources within and adjacent to the City. B. Applicability. The requirements of this Section will apply to all areas indicated as “Habitat Connectors” on the Habitat Blocks and Connectors map, except as follows: (1) Lots or parcels of less than one (1) acre existing as of the effective date of these Regulations. (2) Land located within 50 feet horizontal distance of a principal building existing on the same parcel as of the effective date of these regulations. C. Standards. (1) The applicant shall retain a 150-foot wide Habitat Connector where indicated on the Habitat Blocks and Connection Map. (2) Contiguous Hazards, or other contiguous protected natural resources regulated in Article 12, may be used to count towards the connector width. (3) Habitat Connectors shall be subject to the provisions of 12.05(F) Habitat Blocks Standards. (4) Relocation of Habitat Connector. An applicant may apply to relocate a Habitat Connector from its location on the Habitat Blocks and Connection Map but must connect to mapped Habitat Connectors or Habitat Blocks on adjacent parcels. Any relocated portion shall be accompanied by a restoration plan, prepared by a qualified consultant (e.g. landscape architect, professional wildlife biologist or equivalent). The restoration plan shall consist of planting native tree species (at least 2 inches in caliper) within areas of the relocated Habitat Connector and shall result in the land functioning as wildlife habitat within a period of ten (10) years time. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 35 (5) Restoration of Habitat Connector. The DRB shall require restoration of a Habitat Connector on parcels where development is proposed and pre-existing conditions consist of Habitat Connectors that are less than 150 feet in width along their entire length of the Habitat Connector. Restoration shall consist of planting native tree species (at least 2 inches in caliper) within areas of the Habitat Connector less than 150 feet wide. The applicant may request, in writing, to waive this requirement. The DRB may grant a waiver only if restoration of the Habitat Connector is not possible due the placement of pre-existing structures on the subject parcel. 12.07 Habitat and Disturbance Assessment (HDA) A. Purpose. The Habitat and Disturbance Assessment (HDA) is a tool to inventory and quantify significant wildlife habitat, and the existence of rare, threatened and endangered species (RTEs), within subject properties with mapped Habitat Blocks and Habitat Connectors (Section 12.05 and Section 12.06) where an applicant is seeking to relocate a portion of the Habitat Block or Habitat Connector. B. HDA Content Requirements. Where an HDA is required by these regulations, the applicant shall contract with a qualified wildlife biologist or ecologist to prepare the HDA. The HDA prepared for the Development Review Board shall include the following information: (1) Site Conditions Map including all Habitat Blocks and Habitat Connectors as indicated on the Habitat Block and Connectors map on or within 200 feet of the project site. (2) An inventory of existing (pre-development) wildlife habitat found on the site, including the presence of rare, threatened, and/or endangered species and significant wildlife habitat, and an inventory of the specific types of habitat found on the parcel and their relative importance to the various wildlife species that rely on that habitat for one or more life-cycle function; (3) An assessment of the relationship of the habitat found on the site relative to other significant wildlife habitat present in the City (e.g., does habitat found on the parcel provide for connectivity between mapped habitat blocks; is the parcel located contiguous to other significant wildlife habitat, or part of a habitat block); (4) Identification of the distance of all proposed development activities (as permitted), including clearing, driveways and infrastructure, and areas of disturbance, from the significant wildlife habitat and, if significant habitat is proposed to be disturbed, the total area of disturbance and the total area of the remaining (undisturbed) habitat; (5) An assessment of the likely impact of the proposed development, including associated activities (e.g., introduction of domestic pets, operation of vehicles and equipment, exterior lighting, introduction of non-native species for landscaping) on the ecological function of the significant wildlife habitat found on the site. This shall include an assessment of whether travel between areas of core habitat will be disrupted; (6) An assessment of the anticipated functionality of the Habitat Block with proposed mitigation measures and a statement identifying specific mitigation measures taken to avoid or minimize the proposed development’s impact on the habitat, including buffers of habitat for specific identified species, possible replacement or provisions for substitute habitats that serve a comparable ecological function to the impacted habitat, and/or physical design elements to incorporate into the project. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 36 12.08 Stormwater Management A. Purpose. The purpose of this section is: (1) To promote stormwater management practices that maintain pre-development hydrology through site design, site development, building design and landscape design techniques that infiltrate, filter, store, evaporate and detain stormwater close to its source; (2) To protect water resources, particularly streams, lakes, wetlands, floodplains and other natural aquatic systems on the development site and elsewhere from degradation that could be caused by construction activities and post-construction conditions; (3) To protect other properties from damage that could be caused by stormwater and sediment from improperly managed construction activities and post-construction conditions on the development site; (4) To reduce the impacts on surface waters from impervious surfaces such as streets, parking lots, rooftops and other paved surfaces; and (5) To promote public safety from flooding and streambank erosion, reduce public expenditures in removing sediment from stormwater drainage systems and natural resource areas, and to prevent damage to municipal infrastructure from inadequate stormwater controls. B. Applicability (1) These regulations will apply to all development within the City of South Burlington where one-half acre or more of impervious surface area exists or is proposed to exist on an applicant’s lot or parcel. (2) If the combination of new impervious surface area created and the redevelopment or substantial reconstruction of existing impervious surfaces is less than 5,000 s.f. then the application is exempt from requirements in this Section 12.08. (3) Applications meeting the criteria set forth in section 12.08(B)(1), and not exempt under section 12.08(B)(2), shall meet the application requirements in Section 12.08(C) and the site design requirements in section 12.08(D) as follows: (a) If the area of the lot or parcel being redeveloped or substantially reconstructed is less than 50% of the lot’s existing impervious surface area, then only those portions of the lot or parcel that are being redeveloped or substantially reconstructed must comply with all parts of Section 12.08(D). All new impervious surface area must meet the site design requirements of section 12.08(D). (b) If the area of the lot or parcel that is being redeveloped or substantially reconstructed exceeds 50% of the lot or parcel’s existing impervious surface area then all of the lot or parcel’s impervious surfaces must comply with all parts of Section 12.08 (D). All new impervious surface area must meet the site design requirements of Section 12.08(D). C. Application Requirements. Applicants required to comply with Section 12.08 shall provide the following information in their application: (1) Sub-watershed boundaries and drainage area delineations for all stormwater treatment practices. (2) Location, type, material, size, elevation data, and specifications for all existing and proposed stormwater collection systems, culverts, and stormwater treatment practices. (3) Soil types and/or hydrologic soil group, including the location and results of any soil borings, infiltration testing, or soil compaction testing. Infiltration testing shall be completed using methods identified in the VSMM (see section 4.3.3.2 in the 2017 VSMM, or as updated). LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 37 (4) A brief written description of the proposed stormwater treatment and management techniques. Where Tier 1 practices are not proposed (see Section 12.08(C)(1)(a)), the applicant shall provide a full justification and demonstrate why the use of these practices is not possible before proposing to use Tier 2 or Tier 3 practices. (5) A detailed maintenance plan for all proposed stormwater treatment practices. (6) Modeling results that show the existing and post-development hydrographs for the WQv storm event, the one-year, twenty-four hour rain event, and the twenty-five year, twenty-four hour storm event (rainfall amounts to be determined using NOAA, Atlas 14 data and a type II rainfall distribution). Any TR-55 based model shall be suitable for this purpose. The intent of the twenty-five year storm event analysis is to ensure the proposed project does not overload an existing downstream drainage structure(s) and result in damage to private or public infrastructure or property. The analysis is also intended to ensure that stormwater infrastructure installed as a part of a development can accommodate future upstream development. (7) The applicant’s engineer must provide such information as the stormwater superintendent or designee deems necessary to determine the adequacy of all drainage infrastructure. D. Design Requirements - On-Site Treatment. Applicants shall meet the following standards for on-site treatment of stormwater: (1) The Water Quality Volume (WQv) as defined in the Vermont Stormwater Management Manual (VSMM) for the lot or parcel’s impervious surfaces shall not leave the lot via overland runoff and shall be treated using Tier 1 practices as detailed in the VSMM. (a) If it is not possible to treat the volume of stormwater runoff using a Tier 1 practice as specified in Section 12.08(D)(1) due to one or more of the following constraints: (i) Seasonally high or shallow groundwater, (ii) Shallow bedrock, (iii) Soil infiltration rates of less than 0.2 inches per hour, (iv) Soils contaminated with hazardous materials, as that phrase is defined by 10 V.S.A. §6602(16), as amended, (v) The presence of a “stormwater hotspot” as defined in the VSMM, or (vi) Other site conditions prohibitive of on-site infiltration runoff subject to the review and approval of the Development Review Board, then the WQv shall be treated on the lot using Tier 2 practices as described in the most recently adopted version of the VSMM. A site with an existing Tier 3 practice is allowed to evaluate retrofitting/expanding this practice to meet the requirements of Section 12.08(D)(2). Existing Tier 3 practices shall only be used to satisfy the requirements of Section 12.08(D)(1) in accordance with the Water Quality Practice Selection Flowchart in the VSMM. (2) The post-construction peak runoff rate for the one-year, twenty-four hour (rainfall amounts to be determined using NOAA, Atlas 14 data and a type II rainfall distribution) rain event shall not exceed the existing peak runoff rate for the same storm event from the site under conditions existing prior to submittal of an application. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 38 (3) Applicants who demonstrate that the required control and/or treatment of stormwater runoff per section 12.08(D)(1) and 12.08(D)(2) cannot be achieved for areas subject to these regulations per Section 12.08(B) may utilize Site Balancing as defined in these Regulations. (4) New drainage structures shall comply with the following standards: (a) All drainage structures must be designed to safely pass the twenty-five year, twenty-four hour (4.0 inch) rain event (rainfall amounts to be determined using NOAA, Atlas 14 data and a type II rainfall distribution); (b) Concrete risers, not brick and mortar, must be used to achieve the necessary drainage structure elevation. (c) Driveway culverts must have a minimum diameter of 18” and 12” of cover above them. E. Design Requirements – Impacts to Municipal System. Stormwater runoff from sites meeting the requirements of Section 12.08(D), or sites that are exempt from §12.08(D), may discharge to the municipal stormwater system, or a stormwater system within a proposed future municipal right-of-way, provided that the stormwater system has adequate capacity to convey the twenty-five year storm event from the contributing drainage area. All applicants shall meet the following standards if it is determined that their project may have impacts to municipal stormwater system: (1) New drainage structures connected to the municipal stormwater system, or a stormwater system within a proposed future municipal right-of-way, shall comply with the following standards: (a) New drainage structures should be located within the street right-of-way (b) All drainage structures must be designed to safely pass the twenty-five year, twenty-four hour (4.0 inch) rain event (rainfall amounts to be determined using NOAA, Atlas 14 data and a type II rainfall distribution); (c) Drainage pipes must have a minimum diameter of 15” and be connected to drainage structures using booted connections. (d) Concrete risers, not brick and mortar, must be used to achieve the necessary drainage structure elevation. (e) House footing drains shall only be connected to drainage facilities located in the street right-of- way when a suitable location to daylight the footing drain cannot be found. (f) Footing drains must not be connected to road underdrain. (g) Any footing drains connected to drainage facilities in the street right-of-way shall be provided with a backflow preventer. (h) Driveway culverts must have a minimum diameter of 18” and 12” of cover above them. (2) Drainage Structures To Accommodate Upstream Development. Culverts, pipes, or other drainage facilities shall be of sufficient size to accommodate potential runoff from the entire upstream drainage area, whether or not all or part of the upstream area is on the applicant’s lot or the parcel subject to the application. In determining the anticipated amount of upstream runoff for which drainage facilities must be sized, the applicant shall design the stormwater drainage system assuming the total potential development of upstream drainage areas. All drainage structures shall be designed to, at a minimum, safely pass the twenty-five year, twenty-four hour rain event (rainfall data to be determined using NOAA, Atlas 14 and a type II rainfall distribution). LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 39 (3) Responsibility for Downstream Drainage Structures. In instances where the Stormwater Superintendent anticipates that additional runoff incident from a proposed development may overload an existing downstream drainage structure(s) and result in damage to private or public infrastructure or property, the DRB shall impose conditions requiring the applicant to incorporate measures to prevent these conditions, notwithstanding whether such improvements are located on or off the applicant’s property. F. Intermittent Stream Alteration and Relocation Standard. (1) Alteration of Intermittent Streams. When a development incorporates Tier 1 or Tier 2 stormwater treatment practices (as defined in the VSMM) to manage the stormwater that an intermittent stream is conveying in pre-development conditions, the intermittent stream may be altered or relocated as part of stormwater treatment, provided the stormwater management system meets all standards in this Section. An alteration or relocation of an intermittent stream is exempt from the Vermont Stream Alteration Rule. 12.09 Steep Slopes A. Purpose. It is the purpose of this Section to protect the City’s areas of steep and very steep slopes, as mapped and delineated for this purpose, in order to: (1) Prevent erosion and avoid stream sedimentation that may cause undue adverse effects on water quality. (2) Prevent hazards to life and property resulting from slope instability or failure, including rock falls, slides, slumps and other downslope movements of materials or structures. (3) Maintain and re-establish vegetation on steep slopes to stabilize soils. (4) Ensure that development on steep slopes is constructed and maintained in conformance with best management practices for construction, stormwater management and erosion control. B. Applicability. All development is subject to the standards below where steep slopes or very steep slopes are present. C. Application Submittal Requirements. Submittal of a preliminary and/or complete Site Conditions Map (as applicable to the stage of application) pursuant to Appendix E. An analysis of slope stability prepared by a licensed engineer shall also be submitted to ensure that no erosion hazards are created that would have an undue adverse effect on surface waters, wetlands, areas of special flood hazards, or downstream facilities, and any recommended mitigation measures D. Review Process. Per Section 12.01(D), applications involving development on Steep Slopes between 15% and 25% grade shall be reviewed via administrative Site Plan Review (Section 14.09), unless the application is for a single-household dwelling or two-household dwelling, in which case the application may be approved via a zoning permit reviewed by the Administrative Officer. E. Standards. (1) Very Steep Slope Standards. Development other than Restricted Infrastructure Encroachment is prohibited on slopes greater than 25%. LDR-20-01: Environnemental Protection Standards Draft LDR Amendments March 26, 2021 40 (2) Steep Slope Standards. All development must be designed to avoid undue adverse effects on slopes between 15% and 25%. Clearing of vegetation, excavation and filling on steep slopes shall be minimized. All recommendations of the slope stability analysis submitted with the application shall be required by the DRB or Administrative Officer. F. Exemptions. (1) Removal of Earth Products. Slopes exceeding 15 percent that are created by an approved earth products removal use shall be exempt from the regulations of this subsection. 12.10 Restricted Infrastructure Encroachment A. Purpose. The purpose of this section is to define specific types of “restricted infrastructure” that may be allowed to encroach upon a natural resource regulated in Article 12 and to define the standards that shall be met in order for an encroachment to be allowed. B. Types of Development. Restricted Infrastructure Encroachments are limited to the types of development listed in this subsection: (1) Underground public utilities systems (e.g. water, wastewater, stormwater, electric, broadband, telephone).

Updated standards for relocation On-site field delineation 3 Categories of Natural Resources Resources are grouped into three (3) categories: Hazards, Level I Resources, and Level II Resources. • Hazards are resources for which impacts can have significant effects on safety of property or life. They are often regulated at the State or Federal level. They may be large or small in area. Very limited incursions into these resources, particularly for certain infrastructure, may be permitted following review. • Level I Resources are locally-identified natural resources that are typically larger in area and cross multiple properties. The draft regulations allow for limited adjustment of boundaries in certain circumstances and limited incursions under specific circumstances. Credit may be provided for the conservation of these areas through density transfers in certain Planned Unit Development types. • Level II Resources require specific review for any impact, but are not necessarily excluded from development parcels. They are typically smaller in area and/or can be mitigated through careful site design. Background and Context of the Proposed Regulations The proposed modifications to the Regulations draw on the research work of prior Planning Commission efforts, the 2016 Comprehensive Plan, and several studies undertaken by the community in recent years, including the 2015 Open Space Plan, the 2020 Habitat Block and Assessment and Ranking, and the 2020 Interim Zoning Open Space Committee Final Report, among others. Standards and geographic boundaries established by these Regulations were developed based on mapping, research, and consultations with subject area experts. Habitat Blocks and Habitat Connectors included in the proposed Regulation used the 2020 Habitat Block Assessment and Ranking as their starting point. Geographic boundaries, thresholds, standards for allowed modifications or incursions were subsequently established. These draft amendments are proposed to function as one of a collection of tools to support natural resource conservation and thoughtful development in the community in support of the Comprehensive Plan. Findings Concerning the Proposed Amendments The proposed amendments have been considered by the Planning Commission for their consistency with the text, goals, and objectives of the City of South Burlington’s Comprehensive Plan, adopted February 1, 2016. For each of the amendments, the Commission has addressed the following as enumerated under 24 VSA 4441(c): “…The report shall provide a brief explanation of the proposed bylaw, amendment, or repeal and shall include a statement of purpose as required for notice under section 4444 of this title, and shall include findings regarding how the proposal: (1) Conforms with or furthers the goals and policies contained in the municipal plan, including the effect of the proposal on the availability of safe and affordable housing. (2) Is compatible with the proposed future land uses and densities of the municipal plan. 4 The 2016 Comprehensive Plan establishes four (4) principal Goals for the City: Vision & Goals. Here and into the Future, South Burlington is… Affordable & Community Strong Creating a robust sense of place and opportunity for our residents and visitors. • Be affordable, with housing for people of all incomes, lifestyles, and stages of life; • Keep unique features, and maintain or enhance the quality of life of existing neighborhoods; • Be a recognized leader in public education offerings and outcomes; • Provide quality public safety, infrastructure, health, wellness, and recreation services; • Ensure transparent and accessible government. Walkable. Bicycle and pedestrian friendly with safe transportation infrastructure. • Develop a safe and efficient transportation system that supports pedestrian, bicycle, and transit options while accommodating the automobile; • Establish a city center with pedestrian-oriented design, mixed uses, and public buildings and civic spaces that act as a focal point to the community. Green & Clean. Emphasizing sustainability for long-term viability of a clean and green South Burlington. • Promote conservation of identified important natural areas, open spaces, aquatic resources, air quality, arable land and other agricultural resources, historic sites and structures, and recreational assets; • Reduce energy consumption city-wide and increase renewable energy production where appropriate. Opportunity Oriented. Being a supportive and engaged member of the larger regional and statewide community. • Prioritize development that occurs within the community into the higher intensity areas identified within this Plan; • Support a diverse and vibrant economy built on quality jobs, employment centers and a supportive educational and research system; support markets for local agricultural and food products. The 2016 Comprehensive Plan also includes the following objectives and strategies specific to ecological resources in the community: Ecological Objectives Objective 30. Proactively plan for a network of interconnected and contiguous open spaces to conserve and accommodate ecological resources, active and passive recreation land, civic spaces, scenic views and vistas, forests and productive farmland and primary agricultural soils. Objective 31. Conserve, restore and enhance biological diversity within the City, through careful site planning and development that is designed to avoid adverse impacts to critical wildlife resources, and that incorporates significant natural areas, communities and wildlife habitats as conserved open space. 2-107 Ecological Strategies Strategy 67. Substantially restrict new subdivision and development from primary resource conservation areas to include hazardous and environmentally sensitive areas identified, mapped and regulated by the City. Minimize the adverse impacts of new subdivision and development, including resource fragmentation and encroachment, within secondary resource conservation areas, to include those resources of state or local significance as indicated on available resource maps, identified in available inventories and studies, and confirmed through site investigation. Strategy 68. Redefine open space in new developments such that usable, quality open space shall be required. Qualifying open space should include civic spaces, recreation, wildlife habitat, and usable agricultural lands. 5 Strategy 69. Retain healthy and high-quality existing trees, vegetation, and publicly owned natural areas and woodlands. Develop long-range management plans for each area to foster their continued health and use. Strategy 70. Encourage public education about tree functions and tree disease inspection in urban areas through cooperation with the UVM Horticultural Farm and Vermont Department of Forest Parks, and Recreation, Urban and Community Forestry Program. Strategy 71. Maintain the City’s wildlife diversity, including making use of available planning and legal tools such as buffers, transfers of development rights, overlay zoning districts, conservation easements and other tools as appropriate. Strategy 72. Work with adjoining municipalities and regional entities to enact complementary land use policies where wildlife habitat areas cross City boundaries. Strategy 73. Maintain existing overall tree canopy. Set targets to increase overall tree canopy, with a focus on increasing tree canopy in urban areas and residential property parcels as identified in the Report on Existing and Potential Tree Canopy in the City of South Burlington (2014). Strategy 74. Foster passive recreational use of natural areas and identify areas that may be appropriate for an “off -limits” designation due to their fragile nature. And finally, the Comprehensive Plan establishes a series of five categories of Future Land Use, as depicted on Map 11, along with the following statement: “Together, these broad categories are intended to encompass key issues and areas addressed in this Comprehensive Plan and provide an overall framework for implementation of the plan.” • Very low intensity, principally open space. • Lower intensity, principally residential • Medium intensity, residential to mixed use • Medium to higher intensity, principally non-residential • Medium to higher intensity, mixed use The proposed Regulations substantively and substantially advance the ecological goals and strategies enumerated in the 2016 Comprehensive Plan, and do so in the context of the overall Vision and Goals for the City and the designations within the Future Land Use Map. The proposed regulations have been prepared following detailed evaluation of each individual resource as well as their collective and coordinated roles in support of the objectives and strategies above. The specific resources included within the draft Environmental Protection Standards are not intended to be a precise replication of the individual resources as described or mapped in the Comprehensive Plan; South Burlington-specific study and analysis of these resources, consideration of best practices in resource conservation, and consideration of the geographic context of natural resources across the City were important factors in developing regulatory tools to implement these objectives and strategies. The amendments have been considered for their impacts on the availability of safe and affordable housing. Establishing restrictions on certain land as priority areas for conservation of natural resources can affect the total land area available for the construction of new housing. The existing and proposed regulations mitigate the effects of this conservation, through several means: 6 • Existing regulations allow for the re-allocation of allowable housing density within a property through the use of Planned Unit Developments. • The draft Regulations accommodate circumstances where certain natural resources – notably Habitat Blocks and Habitat Connectors - are present across the substantial majority of the land. • The draft regulations provide for reduced standards, exemptions, or allowable modifications within areas designated as Medium to Higher Intensity in the Future Land Use Map • Recent prior amendments to the Land Development Regulations have increased building height allowances along principal transportation corridors, established inclusionary zoning requirements, and reduced or eliminated minimum parking standards • The proposed regulations are intended to provide greater clarity and certainty for all parties involved in land development (3) Carries out, as applicable, any specific proposals for any planned community facilities. The proposed amendments do not directly affect planned community facilities. Planned Community facilities are specifically addressed through reference to the Official Map. SOUTH BURLINGTON PLANNING COMMISSION MEETING MINUTES 3 MARCH 2021 1 The South Burlington Planning Commission held a special meeting on Wednesday, 3 March 2021, at 7:00 p.m., via Go to Meeting remote technology. MEMBERS PRESENT: J. Louisos, Chair; B. Gagnon, T. Riehle, M. Ostby, M. Mittag, D. Macdonald, P. Engels ALSO PRESENT: P. Conner, Director of Planning and Zoning; J. Nick, A. Luzzato, C. Long, S. Dooley, F. Von Turkovich, A. Jensen-Vargas, S. Partilo, A. Chalnick, R. Greco 1. Agenda: Additions, deletions or changes in order of agenda items: No changes were made to the agenda. 2. Open to the public for items not related to the Agenda: No issues were raised. 3. Planning Commissioner announcements and staff report: There were no announcements or staff report. 4. Continued Land Development Regulations Work Session: a. Review of provisions for waivers/alternative development standards in the draft LDRs: Mr. Nick noted that the Hill Farm has a lot of forest blocks, wetlands, etc. He asked if there is some flexibility. He also noted a fair amount of invasives on the edges. One concern is that if there are house lots, there is a question of who owns the woodlands. He wanted to encourage kids to get outside, and there is an opportunity to have house lots with some woodlands (50 feet into the woods). He cited the Deer Run development where very few trees were removed. There are no pools in the woods, and there is plenty of wildlife. Another concern is that he wouldn’t want the regulations to preclude Swift St. Extension or Exit 12B. He noted the number of times he has heard “what you’re saying makes sense, but that’s not what the regulations say” in his work in various communities. He asked members to keep that in mind. Ms. Louisos thanked Mr. Nick for that feedback. 2 Regarding waivers, Ms. Louisos questioned how much flexibility to allow. She felt flexibility for better design was OK and suggested that “waiver” may not be the best word. Mr. Conner agreed and said “waiver” usually means doing away with something. A modification is more typical of what is done (e.g., reducing a setback by a foot or so for a better project). There is also a provision for “alternative compliance” as in City Center. “Show us something better.” Ms. Ostby questioned whether the Commission had decided that 25 percent will be the number for steep slopes for Level 1. Mr. Conner said that is in the draft, but it can be changed if the Commission chooses to. Ms. Ostby felt they would have to circle back to that at some point. Mr. Riehle said he doesn’t care what the angle is as long as it doesn’t create erosion. He felt they may not need a percentage. Mr. Riehle then asked about zoning district boundaries and the ability to apply the regulations of one district 50 feet into an adjacent district. He asked about buffering. Mr. Conner said there is a buffer required from a commercial to a residential district. If the uses are the same, there is no buffer required. Mr. Riehle asked about 4-plexes put down behind single family homes. Mr. Conner said the rule is that a building can’t be more than one story higher than buildings in an adjacent area. Mr. Macdonald asked if there is any other district other than City Center where there can be impact to a Class 2 wetland. He cited the proposed industrial park on Rt. 116 which is targeted for office/commercial use. He asked if development would be eliminated there because of the wetland. He saw that as an “unintended consequence” since that’s where the city is looking for jobs, etc. He would like to see that area lumped in with the City Center regulations. Ms. Ostby noted that area would also be involved if the 12B interchange is built. She felt it might have to be revisited in the future, but in the meantime supported sticking with the wetland plan. Mr. Gagnon noted they had talked about this and agreed regarding wetland buffers and whether to allow any disturbance in the buffer. Currently this can happen with mitigation, but the Commission decided not to allow impact on the buffers. He was concerned with saying one area is different from another and having people ask for more exceptions. Ms. Louisos noted they went with a moderate approach by not making the buffers any wider. Ms. Louisos asked for public comment. There was none made. b. Traditional Neighborhood Development PUD Type Review: debrief on presentation/illustrations from 2/23, feedback on the results of TND development calculator; discuss potential adjustments to the “levers” affecting development and other TND design elements; overview of “mixed-use” component: 3 Mr. Mittag questioned the 11C table and said he was proposing to make concerned with making things more comfortable for people who may continue to work from home. Mr. Conner asked Mr. Mittag to share his thoughts with him directly to help with drafting. Mr. Conner asked members if anything from Mark Kane’s presentation “jumped off the page” that they weren’t expecting. Mr. Riehle said he still has an issue of tri and quad plexes and the purpose of the Southeast Quadrant (SEQ). He felt inclusions of those units could change the SEQ so it is no longer the rural part of the city. He noted that 3 Burlington City Council members have “fled” to South Burlington’s SEQ. Mr. Riehle also felt the tri and quad plexes would also probably be rental units, and he didn’t feel that renter support the city with taxes, etc. Ms. Louisos said if they break up the land into 1.2 acre pieces, you can see the houses, but you use up more land. She acknowledged that a quadplex in the middle of nowhere could look imposing. Mr. Gagnon said one of the things used to address the quadplex is the construction style which would have the buildings look like single family homes. There would also be a matched look and feel of the houses in the neighborhood. He felt they should make sure building types match a neighborhood. Regarding renters, Mr. Gagnon said this can be great or not so great, and he didn’t know how to address that. He noted that there are single family homes rented to students, and that can’t be banned. Ms. Louisos suggested a possible limit on some types of houses in a location. The multi-family homes could be in the center, and certain groupings could create a homogeneous sense. Ms. Ostby urged members to be more open-minded about renters. She noted that 40% of South Burlington residents are renters, and they pay taxes through their rents. She added that it is very difficult to be homeowners these days, and renters can be very vibrant members of the community. Mr. Mittag was concerned with crafting regulations recommended that regulations be written that anyone can understand. Ms. Louisos said that Mr. Kane had said it was a junior person in the company who drew the plans from the text. Mr. Conner said he had a debrief with Mr. Kane after the presentation. They felt it might make sense to cap the percentage of multi-family homes and to stress that multi-family buildings types would have the form and feel of a single family home. Mr. Conner also noted that the biggest challenge the drafter had was to hit the numbers exactly. The suggestion is to give the 4 DRB a 3-4% ability to deal with unique circumstances. Ms. Ostby felt that was a good idea. She noted that everything she tried always had a little land left over. Ms. Jensen-Vargas said she is a renter, and the ability of not having to deal with upkeep (e.g., mowing, plowing, etc.) gives her more time to do more for her community. It also reduces heating costs, which makes it more affordable. Ms. Dooley noted there are already places in the SEQ with multi-family units (e.g. South Village). She also pointed out Bayberry Commons in Burlington which has some interesting streets. Some buildings look like duplexes, but in the back there are 2 more units. She cited the importance of the neighborhood feel. Mr. Riehle asked about the 10 units mentioned on one page. Mr. Conner said that is a total of housing units: two 3-plexes and one 4-plex. Ms. Ostby reminded members that development can be more dense because they are conserving more land. Mr. MacDonald said that is a good point, but he wasn’t sure how to explain that to the public. He was concerned that the building type approach still leaves gaps as to density. Mr. Conner said the maximum allowable density isn’t necessarily what developers are looking for. Having building types, percentages, etc., is providing more certainty. Mr. Chalnick said some properties won’t look very different. If they don’t have hazards, etc., there could be a huge number of houses. He wasn’t sure that much more land is being conserved. Mr. Mittag took issue with the word “conserved.” It is not necessarily more conserved space but more open space in the development. Ms. Ostby said they have also added hazards and level 1 resource areas that can’t be built on. People can build more in the buildable areas. Ms. Louisos added that there is also civic space that is not lawn. It is usable open space. Mr. Von Turkovich said he is very interested in building typology. He tends to be drawn to the “stacked flat” building of 3-5 stories. He asked if you can build a 2-story building of that type. Mr. Conner said possibly. Typically, it would be located in the higher density area or in a transition area. He will bring that idea to the consultant. Mr. Von Turkovich said it is a very efficient building design. He noted that 3 story buildings become expensive because of elevators. He asked whether the DRB would be allowed to modify a building type and noted the need to make room for “evolution.” Ms. Louisos said that each PUD would have to have multiple building types. In a TND, there would be a more traditional neighborhood feel. Buildings would like more like single family homes. Mr. Gagnon added that there will be percentages of each required building type, and the Commission is still working on those percentages. 5 Mr. Conner said in the current draft, with 10 acres, a developer would select a minimum of 3 building types and a percentage of each, with no more than 50% of any one type. Developers would have the flexibility to do something that will fit well in a neighborhood context. Ms. Ostby said that where they are being proscriptive is with the need to have a cohesive neighborhood with flexibility in design. Mr. Conner said the rules say very little about architectural style other than having a building present a front door to the street or to a center green. Ms. Ostby said that South Village and the new O’Brien development are following a lot of what the new PUDs will have. She also noted that Mr. Von Turkovich’s new development does this as well. Mr. Conner added that the Kirby Cottages are a good example of what a cottage block could look like. Ms. Ostby said the 1.2 units per acre has never been an average in a specific development. It is an average for the whole SEQ. Mr. Riehle was concerned with having 90% multiplexes (e.g., 40% duplex and 50% higher multiplexes) with only 5% single family. Mr. Conner said it may be appropriate to put a cap on the multiplexes in a neighborhood. He noted that in the Rye development, there are 12 “cottages,” 12 4-plexes, and 27 single family homes. Mr. Riehle said the neighborhoods cited are lovely. He is just concerned with the potential. Ms. Louisos noted that some housing types are very similar. The proposal is for a minimum of 15% of a type and a maximum of 50%. She suggested that possibly the sum of multiplexes should be 50%. Mr. Conner added that they may want to lump town homes and multiplexes. Mr. Gagnon agreed with capping multiplexes with possibly a higher cap in the Transit Overlay District, lower elsewhere. Ms. Ostby asked if a development commits to a “tighter” neighborhood, could there be flexibility for 2 types, duplex and single family. Ms. Louisos suggested that another type could be a small house on a small lot. Mr. Conner showed photos of what “small lots” look like in South Burlington including City Center, Village at Dorset Park, Kirby Cottages, and also 5 Sisters in Burlington. He also noted there is a range of building types and sizes in Queen City Park, Blackberry Lane (off IDX Drive) and South Village. Southpoint has small single family homes. Mr. Conner then asked if members wanted to “play around” with allocations. Mr. Gagnon said he wanted caps, with higher caps in the Transit Overlay District. Ms. Ostby suggested decreasing the minimum lot size from 5000 sq. ft. to 3800 sq. ft. Mr. Conner asked to let staff toy with that idea and possibly suggest an additional building style. 6 A straw poll of members indicated a positive response to caps. Ms. Louisos noted that the minimum for civic space is now 10%, but 15% has been suggested. Mr. Conner said that is achievable, especially with smaller lots. Members gave a thumbs up to 15%. Ms. Ostby asked if there should be an allowance for a larger house. Mr. Conner said they shouldn’t go beyond 10,000 sq. ft. because then you lose the neighborhood feel. He added that there could be a “peculiar parcel” where there is some flexibility. Mr. Riehle asked if the intent is to preclude houses such as those at Butler Farms. Mr. Conner said generally yes, in the sense that the lots are somewhat larger and there are no focus points to the neighborhood, but you can still get a large house on 10,000 sq. ft. Ms. Ostby asked about accessory apartments. Mr. Conner said that State law allows a single family home to have an accessory apartment in the same or an appurtenant building. In an adjacent building, you must meet the required setbacks, etc. Ms. Dooley applauded the inclusion of smaller houses, especially from an energy point of view. Mr. Conner then addressed how commercial uses fit into the TND. He said there are a few options. There could be a community building for use by the neighborhood. There could also be some authorized non-residential uses such as small retail, restaurant, personal instruction, but it would be capped at 5000 sq. ft. per use. There could also be a vertical mixed use with a store and apartments above it. Ms. Ostby said she has heard people ask to allow for childcare. Mr. Conner said staff was 100% supportive of that, and indicated he thought it was in the current draft but would confirm. Members gave a thumbs up for childcare inclusion. Mr. Gagnon said that in addition to a square foot limitation, there should be a standard that the commercial building matches the architecture of the neighborhood. Mr. Conner said there are guidelines for that and they have worked fairly well. Ms. Dooley noted there are some uses protected by the State including a group home for no more than 6 people with developmental disabilities. Registered child care can go up to 6 full- time in-home. Ms. Louisos also noted accommodations for home businesses and people working from home. 7 5. Review/possible action on possible updated meeting participation guidelines: Ms. Louisos showed the list of proposed guidelines for public participation. Mr. Mittag moved to approve the guidelines for public participation and Commissioner guidelines as shown. Mr. Gagnon seconded. Motion passed unanimously. Ms. Ostby asked about the procedure to get something on an agenda. Ms. Louisos said to ask her or Mr. Conner. There can also be a short discussion under “other business” about adding something to a future agenda. Mr. Conner said the “other business” discussion would not violate the open meeting law. He also noted there is some authority for the Chair to delay addressing an item if it interrupts another discussion. 6. Other Business: Mr. Conner reminded member that their next meeting is 10 March, 7 p.m. The next night is the joint meeting regarding the I-89 corridor study at 5 p.m. As there was no further business to come before the Commission, the meeting was adjourned by common consent at 9:05 p.m. ___________________________________Clerk SOUTH BURLINGTON PLANNING COMMISSION MEETING MINUTES 3 MARCH 2021 1 The South Burlington Planning Commission held a regular meeting on Tuesday, 9 March 2021, at 7:00 p.m., via Go to Meeting remote technology. MEMBERS PRESENT: J. Louisos, Chair; B. Gagnon, T. Riehle, M. Ostby, M. Mittag, D. Macdonald, P. Engels ALSO PRESENT: P. Conner, Director of Planning and Zoning; A. Bolduc, City Attorney; R. Gonda, M. Cota, V. Bolduc, I Genzhiyev, A. & A. Chalnick, S. Dooley, S. Dopp, R. Greco, J. Bellavance, S. Partilo, A. Jensen-Vargas, D. Peters, L. Yankowski, R. Brinkerhoff, C. Trombly, D. Seff, D. Crawford, B. Sirvis, J. Simson 1. Agenda: Additions, deletions or changes in order of agenda items: No changes were made to the agenda. 2. Open to the public for items not related to the Agenda: Mr. Cota introduced himself as the new City Council member and invited Commission members to reach out to him at any time. Ms. Louisos commented that it is good to have another City Council member with a DRB background. 3. Planning Commissioner announcements and staff report: Ms. Ostby noted that the renovation of the People’s Bank building will result in half of the building becoming residential. She thanked Mr. Conner for spending time to explain how TDRs would work with building types. She also noted that she held another phone information session regarding the “calculator” concept. Ms. Louisos said she spoke with the City Council Chair and they will look to schedule a joint session with the Council in the next few weeks regarding the “calculator”, planned unit developments, and other work under Interim Zoning. 4. Commission reflections on Open Meeting guidance: Q & A. with City Attorney Andrew Bolduc: Ms. Louisos advised that Commission members had watched a video on the Open Meeting Law before this meeting. 2 Mr. Mittag asked if it is a requirement that all documentation that is to be discussed is available to the public before a meeting. City Attorney Bolduc said yes it should be but is not “fatal” to the meeting warning if it isn’t as long as the public has a chance to see it and respond to it. This is a Constitutional requirement. The Commission is at all times accountable to the public. Mr. Riehle asked about reaching out to other Commission members to get feedback from them. Mr. Bolduc said that is a “chain meeting” and should be avoided. Mr. Gagnon asked about email and sending something of interest to other members. “Reply all” is a violation. Mr. Bolduc said that just distributing information is OK. A member can ask “should we address this at a future meeting?”, and that can be discussed over email as it is only about what will be on the agenda. Ms. Louisos asked whether they are still OK with virtual meetings and whether there will be a time limit. Mr. Bolduc said that for the time being, all virtual meetings are OK. He would advise if that changes. He did not that there is a move in the Legislature to make that a permanent option. Mr. Conner noted that if the Legislature doesn’t extend the time limit, there can be a “hybrid” option in which at least one Commission member would need to be physically present at the “live” meeting site. Mr. Conner asked whether any other requirements have been made by the Legislature other than those which are pandemic-related. Mr. Bolduc said the Legislature hasn’t changed anything regarding social media at this time. The Vermont League of Cities and Towns and the Secretary of State’s office have pamphlets and guidance on the Open Meeting Law. Both talk about social media and conversations between members. He cautioned members to be very careful about commenting. Ms. Louisos said members should be careful about posting anything and to make it clear you are speaking as an individual, not as a Planning Commission member. Mr. Bolduc added that this applies on the staff level as well. He further cautioned members to know what “hat” they are wearing and whom they are addressing. Mr. Conner said that in his 12 years with the city he is most proud of how the community takes these things seriously. He felt it reflects well on the community. 5. Continued Land Development Regulations Work Session: a. Review overall Project Schedule and discuss possibility of advancing Environmental Standards (Articles 10 & 12 and related amendments) in advance of others: Mr. Conner said that although a lot of things are intertwined, he was comfortable with advancing Articles 10 and 12 along with some definition updates, etc. These Articles were 3 designed to stand along and are fairly self-contained. Some subdivision standards support Articles 10 and 12 but don’t rely on them. Taylor still has a few questions for the Commission, and these could be warned in the next couple of meetings. Ms. Ostby said it seems the Commission will want the opportunity to do a last connection of Articles 10 and 12 with the PUDs. This could result in a conversation regarding density. She was concerned with releasing 10 & 12 too soon. Mr. Gagnon felt that if the PUDs are just 2 or 3 weeks behind, he would like to keep everything together. Mr. Conner said he expects the last pages of the PUDs later this month. There is still a discussion to be had as to how the pieces worth together. He noted a potential gap in April (re: impending parenthood) when the Commission can have some discussion of things on the “to do” list without him being present. All in all, he felt the PUDs were likely a few moths behind rather than a few weeks. Mr. Riehle said it gets confusing to go from one topic to another. He felt the process shouldn’t have taken so long. Mr. Mittag said that as they have moved to Article 15, it has become more complex with unintended consequences from the impact of the regulations. And some things haven’t been touched on yet. He felt everything is intertwined. He added that he’d never looked at Chapter 9 until a few days ago and didn’t know that was connected to Article 12. He felt they should complete Article 12 and then look at that. Mr. Macdonald agreed with Mr. Riehle and Mr. Mittag and felt he didn’t have a full wrap-up on Article 12. Mr. Conner reminded members that if they adopt something, it can be changed. He didn’t recommend doing that too often, but regulations can always be adjusted. Mr. Mittag noted there will likely be changes after the public hearing. He favored focusing on one thing at a time. Ms. Ostby said the benefit of the City Council getting Articles 10 and 12 is that they may have to make a decision about certain parcels and may have some other open space conversations. Ms. Greco said it is easier to absorb one article at a time. She added that if the Commission is having a hard time grasping things, imagine the public. Ms. Dooley was concerned about how much time is left in Interim Zoning and was worried about having separate processes as each can have more or less time. She felt the Commission had a head of steam on the PUDs. She didn’t see separating things as a time-saver. 4 Mr. Gonda said he has tried to follow the progress of the proposals but has found it confusing. He noted that Mr. Conner gave 2 updates to the Natural Resources Committee, and they are also befuddled. Concerns include: not seeing that the Open Space Report was taken into account, and the focus on “acreage” as opposed to “quality” when considering protections. Ms. Louisos felt there would be more productive public comment if the Commission were more focused. Mr. Mittag said he has a lot of questions to get clarified. He didn’t feel there had been a decision as to whether some of his recommendations were accepted or not. He also said there are things in Mr. Conner’s memo that he hadn’t thought about. Mr. Conner suggested having a “straw poll” on recommendations so there is a record of the Commission’s decisions. Mr. Gagnon then moved to proceed with completing Articles 10 and 12 and related items in order to advance them to public hearing and to the City Council as a first priority. Mr. Macdonald seconded. Motion passed unanimously. Mr. Gagnon said it would be good to have a final mark-up before warning for public hearing. Mr. Conner said the next step will be as clean a draft as possible. Mr. Gagnon said he would like to see a clean version without “bubbles.” Mr. Conner said the Commission can make any changes after the public hearing, as long as they are not things the Commission has never discussed. Ms. Greco asked if the public will get a clean version before the public hearing. Mr. Conner said the public hearing will be warned 15 days in advance, and the document must be available to the public. Ms. Louisos reminded members of the possible joint work session with the Council. She suggested this take place after a clean version is released but before the public hearing. Mr. Conner noted that the Commission would not have to warn a second public hearing if they make changes after its public hearing. If the City Council makes changes after their public hearing, they must warn a new public hearing. Mr. Engels said it would be good to have a document accompany what is sent to the City Council to explain what is being sent and to include pictures. Mr. Conner said there is a 2-page document that described things. He will consider pictures. Mr. Mittag said the deletion of Article 9 will have a big impact on Article 12. He felt stated there is more work to be done than they think. 5 b. Continue discussion of options for how to integrate Inclusionary Zoning where currently applicable into PUDs; consider possible expansion/replacement of current affordable housing density bonus structure: Mr. Riehle asked if there is an option to donate land in lieu of inclusionary units. Mr. Conner said there is. Then if the city has land available for housing, developers could be solicited to develop it without having to consider the cost of the land. This has not yet been done. Ms. Louisos said she was comfortable with what is in Mr. Conner’s memo. It doesn’t feel like they would be layering density on density. Mr. Macdonald expressed concern about incentives and the statement that incentives could alter the planned character of a PUD. Mr. Conner said incentives can be part of the regulations. He cited how this works in City Center. This satisfies both the State statute and the intent of the statute. Mr. Mittag asked if he is required to build 16 inclusionary units and builds 3-bedroom units, does he have to build only 8. Mr. Conner said yes but with “an asterisk.” The justification is that this provides family housing. Mr. Mittag felt it was counterintuitive as the city wants as many units as it can get. Mr. Conner said housing studies identify affordably family housing as a big gap. He noted the popularity of 4-bedroom units on Market St. Mr. Ostby added that the new O’Brien development has 3-bedroom homes as inclusionary, and they will be perpetually available to families. Ms. Dooley corrected the above statement and noted that three 3-bedroom inclusionary units count as 2 inclusionary units. Mr. Riehle asked what happens with TDRs in the Southeast Quadrant (SEQ). Mr. Conner said that today affordable units don’t have to buy TDRs. That could be continued as an incentive. Mr. Riehle asked what then happens to TDRs. Mr. Conner said this would only apply to the affordable units. You could still use TDRs in the rest of the SEQ. There is also thought of expanding TDRs throughout the whole city. Mr. Gagnon said that at this point he would support TDRs in the whole city. Mr. Conner said it would be helpful to have Commission guidance as soon as the Commission is comfortable with that. Inclusionary requirements need to be incorporated the sooner the better. Mr. Macdonald asked if inclusionary units would be dispersed among building types. Mr. Conner said they need to be thoroughly integrated into the neighborhood but can be in one 6 building type. They cannot all be in one 20 unit building if there is only one such building. They also need to have the same average number of bedrooms as the rest of the development. Mr. Mittag said he wasn’t ready for city-wide inclusionary zoning until he knew the impact on the SEQ. He felt it was a big change to go from voluntary to mandatory. Ms. Louisos stressed that density is not being increased with inclusionary zoning, and the city is not giving up anything. There is no reason not to consider expanding it further. Mr. Mittag felt that combined with PUDs it could make a huge difference. Ms. Ostby said that today the only way to get affordable housing is to tie it to a density bonus. With inclusionary zoning, affordable units are tied into the underlying density. Mr. Conner said that is correct. Under State law, there must be an “incentive,” but that does not necessarily have to be a bonus. Mr. Conner noted that where inclusionary zoning exists in City Center, it does not increase density. Mr. Gagnon moved to direct staff to move ahead with exploring “a” and “b” on staff’s memorandum to have something ready for when work on Articles 10 and 12 is complete. Ms. Ostby seconded. Members discussed the option to remove “increase base density” from the list of incentives. Mr. Conner said he would ask the City Attorney about that. No one element must be in there, and he comfortable there is a good slate of options. The Court might say the city is not meeting the standard. Mr. Conner also noted that the consultant may have other ideas. Mr. Mittag said a property owner might not want to increase the base density. Ms. Ostby was comfortable with removing that option, if possible. In the vote that followed, the motion passed unanimously. c. Consider proposal from Commissioner Ostby to consider a basic vs. expanded Conservation PUD: Ms. Ostby said she was concerned with people who have 50% of their acreage in hazards or level 1 resources in the SEQ. The focus was to be on those parcels being most impacted. She was concerned with expanding it to take out buildable land so that it would never be developed. She said some people would say they shouldn’t conserve anything permanently because the world changes. Mr. Mittag said that once something is on the books, it’s hard to get rid of it. He felt they need every square inch of meadow, etc. from a climate mitigation point of view. He wouldn’t support Ms. Ostby’s idea. 7 Ms. Louisos said this would be a great conversation when they have the Conservation PUD language in front of them. Mr. Chalnick felt a landowner should have the option to conserve land. d. Overview of related amendments to PUD/Subdivision/Environmental Protection standards updates; Commission prioritization: Mr. Conner asked members to review the memo and think about which subject areas they want to delve deeper into. There are some site plan amendments (e.g., many towns give modification authority to the DRB, especially regarding dimensions). Mr. Conner noted that much of Article 9 (SEQ) is based today on how a PUD should be arranged. If you adopt the TND form of PUD, very little remains in Article 9. What does remain is how TDRs and environment protection work. He has heard that some of the SEQ design elements should be city-wide. Mr. Mittag didn’t see how they could delete such an important part of the LDRs unless those protections are transferred to Article 12. Ms. Louisos suggested putting this on a future agenda. Mr. Conner noted the SEQ is almost self-contained. His suggestion would to place rules where they are logically found. The Commission wanted Article 12 to address natural resources in the city. Ms. Ostby said she couldn’t find the portion of the minutes where there was a recommended change from Industrial-Open Space zoning to Mixed Use. She felt they would need to discuss the Official City Map and in particular Swift Street Extension. Mr. Conner said the area referred to in the memo is immediately south of the Interstate. Article 12 standards on that property would have the western portion in a forest block. Ms. Dopp questioned potential development in the NRP. Mr. Conner said that as drafted nothing about the amount of development is proposed to change in the NRP. There might be a slight modification to the building envelope. Mr. Riehle asked when they would get to the items on Mr. Conner’s memo. Ms. Louisos said these will be addressed when they get into PUDs more. Some items are updates; some are new items. Mr. Conner said they are most closely related to PUDs, though some (e.g., changes in State rules regarding subsidiary dwellings) are not. 6. Provide direction on selection of name for new street adjacent to Library/City Hall: Ms. Ostby suggested going to the Marcotte School students for ideas. Members liked that idea. 8 Ms. Dooley spoke to the issue to naming streets for individuals to erase prior racial injustice. She cited Lavinia Bright, the first woman of color to serve in the Vermont Legislature was from South Burlington. Ms. Dopp noted the possibility of former Librarians. Members agreed to go to the Marcotte students with two topic areas: names that are complementary to Garden Street & Market Street, and names for people of historical significance to South Burlington. 7. Meeting Minutes of 23 February 2021: Mr. Gagnon moved to approve the Minutes of 23 February 2021 as written. Mr. Riehle seconded. Motion passed unanimously. 8. Other Business: Mr. Conner reminded members of tomorrow’s I-89 study meeting to provide feedback to CCRPC on evaluation criteria. He encouraged members to attend. As there was no further business to come before the Commission, the meeting was adjourned by common consent at 9:22 p.m. __________________________________Clerk SOUTH BURLINGTON PLANNING COMMISSION I-89 BREAKOUT SESSION MEETING MINUTES 10 MARCH 2021 1 A quorum of the South Burlington Planning Commission participated in a Joint Meeting/Working Session regarding the I-89 Corridor Study facilitated by the Chittenden County Regional Planning Commission on Wednesday, 10 March 2021, at 5:00 p.m. via Zoom remote technology. Minutes for the joint meeting are with the City Council minutes. The Planning Commission held a “break-out” sessions afterwards with the same Zoom remote technology. Present: Eleni Churchill, Paul Conner, Jessica Louisos, Duncan Macdonald, Michael Mittag, Monica Ostby, Charlie Baker (attended part of the meeting) 1. Breakout room to have individualized conversations and feedback regarding I-89 Corridor Study Interchange Evaluation Criteria Mr. Mittag stated concern regarding impact to wetlands, particularly at the 12B location. Requested wetland impact metrics be included. He has walked the area and cannot see how the proposed location of 12B can avoid the destruction of this wetland. Ms. Churchill stated that there is a wetland metric and an updated 12B concept seemed to address wetland issues but will review. Ms. Louisos requests economic access impact as the interchanges connect to areas of growth. She would like to see a sub set metric of how each exchange contributes and/or detracts from supporting SB City Center. Ms. Churchill indicated that she will discuss this with the consultant team. Mr. Mittag suggested underlying assumptions might not have taken into account that we expect more people to work from home This would mean fewer commutes and fewer cars on the road. Also, a lack of transit for rural residents might lead to the use of robotaxis by rural residents making traditional transit less important. might expect more working from home thus taken into account. Also a lack of transit for rural residents. Ms. Churchill explained that due to the uncertainty of how people will travel in a post- pandemic world, the study will recommend monitoring travel patterns and develop triggers to identify when major roadway capacity improvements are needed so they can move forward. Ms. Ostby stated disappointment that a version of exit 14 with the inclusion or assumption of a separate bike/ped bridge to it's south was not presented. Ms. Churchill explained that the isolated bike/ped bridge is being reviewed as part of the I-89 corridor "bundle" and evaluated separately (in the next phase of the study). That it might be a mid-way project that is constructed prior to an exit 14 reconstruction. And that any exit 14 option should include safest bike/ped facilities even if a separate bridge is constructed. Ms. Ostby also asked if truck/commercial traffic impact not only on each exit but the surrounding city roads be considered. Are there areas of SB that would see a rise in commercial traffic? Ms. Churchill indicated that the regional model provides data on overall vehicle traffic but not necessarily on commercial traffic. The project team already developed maps indicating change in volumes for each of the five interchange concepts. Note: The maps are available on the project website (www.envision89.com) and were shared with the City Council Feb 16, 2021. Regarding exit 13, Ms. Ostby stated safety concerns of heavy truck/commercial on a 4 lane boulevard design connecting I-89 to Shelburne Road. She also asked if the land connected to the southern portion of the current 189 might be converted to bike/ped use. Ms. Churchill explained that since it is Federal land it would have to be invested. They will review how to identify commercial traffic safety impact. Mr. Conner suggested that all exits review what Federal lands would be no longer needed with the new designs and what might happen to that land. That even if the land ownership continued to be Federal 2 and was left alone, what impact would it have on a potential quality of life improvement. He suggested adding a metric of "Return of Valuable Land." Ms. Churchill stated that such questions will be directed to the Vermont Agency of Transportation and Federal Highway Administration. Mr. Mittag asked about the cost impact of creating 12B, how many acres would have to be purchased as is this part of the cost estimate. Churchill confirmed the construction estimates do not include ROW or land acquisition expense. Mr. Mittag supported exit 13 given its direct access to the airport, reducing traffic load to exit 14, and asked that this be considered in a weighted evaluation. Mr. Macdonald asked for clarification of the process. Ms. Churchill explained that while the final decisions on which interchange concepts to move forward for further evaluation are made by the I-89 Advisory Committee, they will give preference to the direction received by the City Council. As part of the process the committee will look at midway options such as bike/ped bridge before final interchange work. That major interchange improvements (permitting, design and construction could take 15 to 20 years. Mr. Macdonald suggested that timing to completion is an important metric that should be included. Mr. Macdonald asked for clarification regarding the two future roads shown on the 12B draft, connecting Tilley Drive to Kimball Ave and to Community Drive.. Mr. Conner confirmed both roads are currently on the Official Map, and one, connecting to Kimball Ave, has its northern half currently under consideration as part of a proposed development. Ms. Louisos reminded that there was a suggestion to consider how the scoring might be weighted. This is a topic the full PC will discuss in an upcoming meeting. Further, should any goals be weighted? Ms. Churchill also ask the committee to review the scoring methodology and offer any comments. Mittag asked how to best engage the community. Churchill reviewed the public sessions already held, and future sessions planned including 3/18 and mid April. Ms. Ostby stated that while reviewing exits 14 and 13 can be clear and constructive, evaluating whether to support a new 12B will be highly political, making it more challenging to be objective. Mr. Macdonald stated reviewing a new construction at exit 12B partial vs a partial reconstruction (such as 14 and 13) would be a much heavier left. Ms. Ostby asked if a metric considering the benefit of each interchange to the surrounding cities can be useful. Mr. Baker stated that earlier research confirms that 12B is not more helpful to Hinesburg residents' access to 89 than using the current 12. Considering the fuller option for exit 13 might review benefits to supporting Burlington. Mr. Baker asked that the PC further contemplate if something more can be weighted, and if any considerations are missing. He also mentioned as an example that in the City Council sub group this evening safety was seen as a higher concern than cost. The meeting was adjourned by common consent at 7:09 p.m. __________________________________Clerk SOUTH BURLINGTON PLANNING COMMISSION MEETING MINUTES 16 MARCH 2021 1 The South Burlington Planning Commission held a special meeting on Tuesday, 16 March 2021, at 7:00 p.m., via Go to Meeting remote technology. MEMBERS PRESENT: J. Louisos, Chair; B. Gagnon, T. Riehle, M. Ostby, M. Mittag, D. Macdonald, P. Engels ALSO PRESENT: P. Conner, Director of Planning and Zoning; S. Dooley, J. Bellavance, A. Jensen-Vargas, A. & A. Chalnick, R. Greco, S. Dopp, N. Hyman 1. Agenda: Additions, deletions or changes in order of agenda items: No changes were made to the agenda. 2. Open to the public for items not related to the Agenda: No issues were raised. 3. Planning Commissioner announcements and staff report: Ms. Ostby advised she had attended last night’s City Council meeting at which Interim Zoning was discussed. She felt it was clear the Council is waiting to hear from the Commission, but she felt there were things the City Council could be doing independently which they are not doing and which would be very helpful to the Commission. Mr. Riehle noted there are 224 units in the DRB hopper pending or about to go through. He asked how many units there are in the city now. Mr. Conner estimated 9000. Mr. Riehle said “growth is happening.” Mr. Mittag said there are also projects being built now. Mr. Conner: On Thursday evening there will be a public meeting regarding the CCRPC I-89 study. Next Tuesday, there will be a presentation to the Planning Commission by the Swift/Spear Street Study Group. Materials will be provided in advance. Mr. Conner said he testified at the Senate Transportation Committee last week regarding a bill to formalize the definitions of electric bikes and what level of control municipalities would to have (e.g., use on rec paths). 4. Commission discuss and prepare feedback on I-89 Corridor Study Interchange Evaluation Criteria: Ms. Louisos noted that feedback needs to go to the CCRPC by next Monday. 2 Mr. Riehle said what comes to mind is a “Pandora’s box” regarding Exit 12B which would connect to Tilley Drive and Swift Street over wetlands in both cases as well as other issues. Mr. Mittag said when he brought up the wetland issue, he was told it is not a problem, but when he walked the area he could not see how it can be avoided. Ms. Louisos said she had mentioned that there were no metrics specific to South Burlington. She felt it would be good to know how the options contribute to/detract from City Center. Mr. Riehle said safety re: bike/ped is still his concern and which option is best for that. None seem to him to be good. 14 and 12B seem the most difficult regarding those safety concerns. Mr. Engels thought 13B was a good idea: no cloverleaf with still an on/off to I-89. He also felt the city should have a direct say since all the interchanges are in South Burlington. Mr. Conner reminded members that the reason for the input is the evaluation criteria, to put data behind why one option is selected over another. Mr. Macdonald said he would be OK with 12B, but he didn’t think it will happen. He was OK with 13 but not either option. He felt it is better to do something where there is a “start.” 13 also puts people closer to City Center and on a 4-lane road direct to the Airport. Ms. Louisos said a partial interchange is more feasible from a time-line point of view. Mr. MacDonald questioned whether that is the case. Mr. Conner said that is the interesting question. Pare of the metric is when bridges need to be upgraded/replaced. He felt Exit 13 is probably more of a project that the one over Williston Road. There is also the issue of on-going appeals. Ms. Ostby said there was talk of a time-line and they were told “new” would take longer. She noted all of this is 15 years out and timing should be considered. She also hoped CCRPC can work out the commercial vs. residential traffic issue. She was concerned with converting I-189 to a boulevard because of the high volume of truck traffic. Mr. Conner noted that some options give land back for natural resources, etc. There may be a way to evaluate the amount of truck traffic that is brought closer to or further from homes and what that means for quality of life. Mr. Mittag asked if they will have the opportunity recommend sequencing. He felt 13 would give the city the biggest bang for the buck and it solves some traffic problems. Mr. Conner said there is already some prioritization, doing things that preclude the need for any of the major options. Ms. Dopp said that some time ago she heard a CCRPC person say one of the 3 options would be dropped out. Mr. Conner said the objective is to have options at each intersection, one at 14 and one at 12/13. Ms. Dooley noted that the prospect of appeals was a major factor in the abandonment of the Circ Highway. 3 Ms. Greco felt the CCRPC should focus on non-car options. She felt there is time to mull this over. She noted this was talked about 10 years ago at a meeting. Ms. Dooley said there are now 6 goals and a plan to weigh them all equally. She also noted that Mr. Baker said safety should come first. Ms. Dooley questioned “whose safety?”. Mr. Conner said safety for all users. He heard that one of the Exit 13 options is less safe with the U-turn, though it is much less expensive. Ms. Ostby said a U-turn is so unexpected that people will get “lost” and frustrated and then hurt. People expect an off-ramp. She felt it is what provides the most predictable path for drivers. Ms. Louios felt “familiar design” is a good way to phrase that. Mr. Mittag noted he has asked whether the metrics of loading could change because of people working from home. Ms. Louisos said travel may be less “carcentric” 30 years out. Ms. Ostby noted the trend to autonomous truck traffic and the potential to see more commercial than “people” traffic. Mr. Mittag noted the possibility of seeing drones for deliveries in the future. Members were OK with Ms. Louisos and staff compiling comments for CCRPC. These will be circulated to members. Mr. Riehle asked when the vote will be. Mr. Conner said the CCRPC will attend the meeting on the 29th. He will check in regarding the timeline. Ms. Louisos said it looks like an April to June timeframe. Mr. Mittag asked whether they should do a “ranked” choice of the goals. Ms. Louisos suggested members who want to do that should send their rankings to her. Mr. Chalnick felt the differences in the options were so small. Ms. Ostby said that Charlie Baker had said 12B doesn’t benefit Hinesburg and that the existing Exit 12 is better. She asked if benefit to other towns should be a consideration. Mr. Engels then moved to authorize Ms. Louisos to submit a letter to CCRPC with the Commission’s comments. Mr. Mittag seconded. Motion passed unanimously. 5. Continued Land Development Regulations Work Session: a. Review updated Environmental Protection Standards following Commission guidance and related amendments: Ms. Louisos said she had a discussion with the Council Chair about the timeline and how helpful it would be than when a Commission public hearing is warned there can be a joint meeting with the Council that would include a deeper view of the PUD work as well. The first week in April was talked about for an update, then warning the public hearing. Ms. Louisos added that in the next few meetings she would like to get a draft out for public comment. 4 Ms. Ostby said that while the Commission agreed to focus on Articles 10 and 12, they didn’t agree on a separate public hearing for 10 and 12. Ms. Louisos said that would be a good topic to discuss at a joint meeting with the Council. Mr. Gagnon said 10 and 12 could still go to the Council and they could hold onto it until they get the PUD stuff. Ms. Louisos stressed that the Commission should focus on policy rather than “nitty gritty” word choices, etc. Members then reviewed specific areas as follows: Definitions: It was noted that there are places where there is reference to “forest blocks” instead of “habitat blocks.” Ms. Ostby felt the “historic site” should be defined. Ms. Louisos said “core habitat” may also need to be defined as it is referred to later on. Description of Districts: Ms. Louisos noted that an old city map had been referred to. Now there is specific information as to what to use. Ms. Ostby said they should indicate what the new Natural Resources Map is replacing. Mr. Conner suggested that be done via a memo. Regulations are the regulations in effect. Mr. Mittag said that where “undue adverse affects” is used, reference to the test (304h) should be made. Mr. Conner said he will see how to draft that some way. Mr. Engels asked whether “building envelope” is the building or the lot. Mr. Conner said that as used here it is the are of the lot allowed to be built within. Article 9 Items: Mr. Mittag felt that environmental protections in the Southeast Quadrant (SEQ) are being removed and they shouldn’t be offering less than what was there before. He felt the old language regarding prime ag soils, grasslands and shrub lands should be included as Level 2 resources. Ms. Louisos said that Articles 10 and 12 would be applicable across all districts. Mr. Engels said he read the Interim Zoning Ordinance and it seems to be a “open space ordinance.” He felt they should be looking to improve open space. He felt it was the Commission’s work to turn the work of the Open Space Committee in LDRs. Ms. Louisos said the Committee evaluated individual properties, and the Commission felt it was more important to indicate under what criteria things would be protected. Mr. Gagnon said the Commission has taken data from a number of sources and have written regulations to be more protective of natural resources (e.g., streams and wetland buffers). For the City Council, the Commission is to provide the regulatory piece. Regarding open space, Mr. Gagnon noted there are other tools available (e.g., purchase), and what is needed are underlying regulations for the land to be used and to strike a balance. If an owner wants to conserve or to sell land for development, there should be a mechanism to do both. Mr. Gagnon also noted that the Comprehensive Plan had many goals, some of which conflict with each other: open space vs. affordable housing. The Commission is trying to strike a balance and has written regulations leaning toward protecting resources but not to the exclusion of everything else. Ms. Louisos said that maps 7 & 8 were incorporated into the Comprehensive Plan as a guide for studies and goals which could eventually be part of the LDRs, part of a purchasing plan for the city, etc. She didn’t think anyone ha the sense that maps 7 & 8 were to be regulatory, and they didn’t put a lot of 5 thought into what was on those maps. Articles 10 and 12 are vetting that now. Ms. Louisos noted that the group that compiled those maps did not have consensus. She added that unfortunately those 2 maps replaced map #6 which was referenced in Article 9. She said map 7 shouldn’t have been regulatory in the first place, and the Commission is now being very specific about what is being regulatory. Ms. Louisos also felt the Natural Resources Committee can work on finding specific grasslands to protect. She stressed that the Commission has protected river resources, added the 500- year flood plain, and done work on habitat blocks and connectors. Mr. Mittag said the Commission never discussed dispensing with Chapter 9. It just happened. It is the current regulation that people have relied on, and he felt it would be “highhanded” to dispense with it. He felt that would result in less environmental protection than now. Mr. Gagnon disagreed that things are being given up. He said he personally wouldn’t regulate grasslands. Ms. Ostby said when she looks at the riparian on Map 7 and what the Commission is protecting, everything is covered and the Commission added to it. She also noted that people can petition the Commission to reconsider other things. Mr. Engels noted that what is redlined out in 906B3 is what the DRB used to rule in favor of the neighbors re: Dorset Meadows. Mr. Mittag acknowledged that riparian is covered, but he still felt agriculture, meadowlands and scrub lands are important. Mr. Macdonald said the Commission had a robust discussion as to what was to be protected in hazards, level 1 and level 2. He agreed not to rewrite Article 9. Ms. Louisos added there is no comprehensive mapping of grasslands, and the maps in the Comprehensive Plan were not vetted for LDRs. Ms. Ostby said the Commission “put a stake in the ground” and it is up to the City Council to give a different directive. Mr. Gagnon noted that the definition of agricultural soils covered everything in the city, so the Commission had decided not to use it. He felt the Commission can agree to disagree. Mr. Riehle agreed they should vote and move on. Mr. Mittag cited a difference between “primary” and “prime ag” soils and noted the latter is more restrictive. Primary soils are everywhere. Prime ag are very limited. Ms. Dopp said “prime ag” is a very specific term. She also noted the IZ Committee commented that open space recommendations should be reflected in the LDRs. She suggested reviewing the Committee’s criteria to make their judgments. Ms. Ostby said that is what the Arrowwood Report did, and the habitat blocks are in those parcels. Mr. Chalnick asked about the history of preserving lands in the SEQ. Mr. Conner showed the 2006 plan map and noted there were 3 primary “natural communities”: the Great Swamp, the Cheese Factory Road Swamp and Van Sicklen Avenue areas. He noted that the references in the Comprehensive Plan can’t be from this source and must be from the 2016 map. Mr. Conner then showed the 2016 map #7 6 and the draft map in this meeting’s packet. He identified various elements in each (e.g., wetlands and buffers, 500-year flood plain). He also indicated in the new map features such as habitat blocks, river corridors, steep slopes, etc. Ms. Ostby said from what she saw, nothing from map #7 isn’t covered by more in the current map. She felt great looking at the 2 maps. Mr. Conner then showed map #8 which identifies primary ag soils, 500-year flood plain, Great Swamp as identified by the State, including different types of forests, and “uncommon species.” Ms. Ostby then moved to accept the resources currently listed in Articles 10 and 12 to put forward in the draft for public comment. Mr. Gagnon seconded. The motion passed 4-3 with Messrs. Mittag, Engels and Riehle voting against. Mr. Mittag then moved that rather than accept the changes in Chapter 9.06 that the protections offered in the current regulations, namely prime agriculture soils, grasslands and shrublands be included in the protections in Article 12 under hazards, level 1 or level 2, and not to abandon those protections. Mr. Engels seconded. Ms. Louisos said she didn’t see this as the only way to cover those things, and she didn’t think a whole new section was needed. Ms. Greco asked if there are more or less areas protected. Ms. Louisos said some areas are bigger, and there are different definitions. Mr. Conner noted that the Comprehensive Plan spoke to “primary areas” but the Land Development Regulation gave no direction as to how to interpret that because there is no specific standard for interpretation. The grasslands, prime ag and shrublands in Map 8 were secondary, and were not tested as to relevance. Mr. Conner then enumerated what is now being covered that was not previously covered including: 500-year flood plain, measurements from streams for buffers, no incursion into wetlands, habitat blocks throughout the city, steep slopes over 20%. He said th is is substantially more than is currently protected. Mr. Conner said that to regulate what Mr. Mittag wants would need specific standards or it would be difficult to uphold. Ms. Dooley noted that Mr. Mittag’s motion contradicts what the Commission just approved. Mr. Mittag acknowledged that. Mr. Engels asked Mr. Conner to indicate what protections are lost. Mr. Conner said the text in Chapter 9 refers to a Comprehensive Plan map which refers to statewide data. It is hard to say what is gained or lost. In the vote that followed the motion was defeated 3-4 with Ms. Ostby, Ms. Louisos, and Messrs. Macdonald and Gagnon voting against. Members agreed to pick up at the next meeting from where they have left. Off. 7 As there was no further business to come before the Commission, the meeting was adjourned by common consent at 9:49 p.m. ___________________________________ Clerk Memorandum To: The City of Burlington Planning Director The City of South Burlington Planning Director The Town of Colchester Planning Director The Chittenden County Regional Planning Commission The Vermont Department of Housing and Community Development From: Eric Vorwald, AICP Planning and Zoning Manager RE: Report on Proposed Amendments to the City’s Unified Land Use and Development Regulations including Articles III and X; and Sections 4.9 and 6.6 DATE: March 12, 2021 ________________________________________ Enclosed with this memo, please find proposed amendments to the City of Winooski’s Unified Land Use and Development Regulations.

Memorandum TO: Planning Commission FROM: Eric Vorwald, AICP Planning & Zoning Manager RE: Report on Proposed Amendments to the City’s Unified Land Use and Development Regulations including Articles III and X; and Sections 4.9 and 6.6 DATE: March 12, 2021 ________________________________________ This memo provides information related to proposed amendments to the City of Winooski Unified Land Use and Development Regulations. These amendments specifically impact the following articles and sections: • Article III - Reserved • Article X - Maps • Section 4.9 - Nonconforming Lots, Structures Right of Way (ROW) or Drive, and Uses • Section 6.6 - Site Plan Review These amendments also replace references to “Appendix C” with “Article III”, move the “Building Height and Location Map” from Appendix C to Article X, and delete Appendix C in its entirety. Background In 2016, the City undertook a comprehensive update to the Unified Land Use and Development Regulations (ULUDR). This was the first update in over 20 years. A major component of this update included a new Appendix B, which provides regulations for the Gateway Zoning Districts through the form-based code. While these changes modernized the regulations, staff has identified additional amendments to provide clarity and improve the interpretation of the regulations. Additionally, several conflicts exist that need to be rectified. With this in mind, staff has been reviewing each section of the ULUDR and proposing amendments to the Planning Commission for their consideration. Purpose of Amendments These amendments are being proposed to provide clarity for interpretation of the regulations, and to update and incorporate specific regulations related to the Downtown Core Zoning District, including regulatory references contained within the standards. The City developed and adopted regulations related to the Downtown Core Zoning District over several years including multiple interim zoning Memo to Planning Commission Proposed ULUDR Amendments March 12, 2021 Page 2 of 16 changes. With the complete update and codification of the regulations, the standards for development in the Downtown Core Zoning District were included as Appendix C, but did not include referential updates. The proposed amendments will incorporate the specific use standards for the Downtown Core Zoning District into Article III (which is currently reserved) and adds language related to the process of review for projects in the Downtown Core Zoning District including the City Council review for design consideration in the Act 250 permitting process including references to the master sign plans that have been adopted for the Downtown Core Zoning District. These amendments also add clarification related to site plan review, including properties in the Downtown Core, as well as clarification for non- conformities including properties in the Downtown Core. Finally, the amendments would replace references to “Appendix C” with “Article III” to recognize the relocation of these regulations. These amendments also add the “Building Height and Location Map” currently included in Appendix C to Article X, which includes other zoning maps. Minor map changes update road names and incorporate the entirety of Cascades Way, but do not change any of the specific regulatory requirements associated with the building heights, locations, or development areas. If approved, these changes will result in the elimination of Appendix C as all information will be relocated to other sections of the Unified Land Use and Development Regulations. Proposed Amendments The following pages include the text of Articles III and X; and Sections 4.9 and 6.6 including proposed changes. Proposed additional text is shown in red and underlined. Text that appears with a strikeout is proposed to be deleted. If specific sections are not included, no changes are being proposed in these sections. For the purposes of this amendment, language contained in Article III has been transposed from Appendix C. While all of this text is new to Article III, the construction of the amendments are intended to reflect existing regulatory language that will remain in the context of changes that are being proposed.

City of Burlington, VT 149 Church Street, 3rd Floor Burlington, VT 05401 Phone: (802) 865-7144 www.burlingtonvt.gov/plan TO: Burlington Planning Commission & City Council Ordinance Committee FROM: Scott Gustin, Principal Planner & Zoning Division Manager Meagan Tuttle, Comprehensive Planner, Office of City Planning DATE: March 22, 2021 RE: Proposed CDO Amendment ZA-20-05: Short Term Rentals & Ch. 18 Minimum Housing Code amendments Overview & Background This package of amendments resulted from the 2019 Mayor’s Housing Summit, and the subsequent Council Resolution in October 2019, which directed a Joint Committee of the Planning Commission & City Council Ordinance Committee to create a regulatory framework for short-term rentals that created tiers and disincentivizes the most impactful uses in order to:  Limit the number of housing units converted for short-term rental purposes;  Ensure that conversions contribute to efforts to preserve and expand affordable housing;  Provide some flexibility for homeowners to earn income; and  Recognize that some supply of short-term rentals benefits the Burlington economy. Defining Short Term Rentals A short term rental (or STR) is typically a dwelling unit that is rented in whole or in part to guests for less than 30 consecutive days for overnight stays. It may be an apartment, a house, or just a bedroom within a housing unit. AirBnB exemplifies short term rentals. In the last several years, there has been significant and growing demand for STR’s internationally, and locally. They benefit owners with a source of income that can help subsidize a cost of living that may otherwise be unaffordable. STR’s may also encourage investment in a property. They benefit Burlington’s tourism economy and provide guests with a convenient, and often more affordable, place to stay when traveling. They also generate city and state tax revenue via the Rooms & Meals Tax (RMT). Short term rentals, however, do not come without impacts. Some have the effect of removing dwelling units for long-term occupancy, and they may contribute to rising rental rates and purchase prices. Given the high turn-over of guests, short-term rentals may bring about nuisance impacts such as traffic, noise, and trash to neighborhoods. As the Joint Committee has heard from many of the city’s STR hosts, short-term rentals are uniquely flexible and come in a variety of forms—beyond the major distinction between whole unit and partial unit STR’s. The same dwelling unit may alternate between long- and short-term rental uses within a relatively short period of time. A dwelling unit may serve as one’s primary residence for most of the year, and serve as a short-term rental while the resident is away. A short-term rental may coexist with a number of long-term rentals within a multi-family building. This variability and flexibility needs to be considered within the context of the overarching policy objective: to protect Burlington’s limited housing stock, while affording reasonable opportunity to host short-term rentals within the city. Short Term Rentals in Burlington Burlington has some 10,000+ rental housing units, representing 60% of all housing units. While the June 2019 Housing Summit reported hopeful trends in a slightly increasing vacancy rate and slight slowing annual rent inflation, the city’s housing market remains tight with the long-time rental vacancy rate between 1% and 2%. Short-term rentals have replaced a growing number of dwelling units citywide in recent years. According to data provided by HostCompliance, the number of short term rentals within Burlington increased 26% between 2018 and 2019. The average monthly number of short term rentals within city limits between June and September 2020 was 403 listings, representing 357 unique rentals. As of September 2020, 71% STRs in Burlington are an entire dwelling unit, whereas 29% are partial dwelling units (i.e. bedrooms). This is a change from 67% and 33% respectively in 2019, likely due to COVID-19 concerns. In September 2020, 55% of the city’s STR’s were in single-family properties and 45% in multi-family properties. The COVID-19 pandemic has had wide-ranging impacts on the STR market globally and locally. While the total number of unique properties and listings in Burlington has changed little in 2020, the number of active listings has varied this year due travel restrictions and hosts’ management decisions. Stories shared by STR hosts and data from other sites, such as AirDNA, suggest that many of these listings may currently be inactive, are being rented as an STR for a longer duration (such as for weeks or months), or are being used as temporary accommodations for people who have relocated due to the pandemic. It will be some time before the long-term impacts of COVID-19 on the local STR market are understood. Joint Committee work on STR Proposal The Joint Committee has received information on STRs in the city during meetings spanning more than a year. In response to public and Joint Committee comments, the original draft regulatory framework has been revised in four major ways:  Revision to STR limits within multi-unit buildings to be less than 50% of units, a prohibition on STRs in buildings with 5 or more units, and a related clarification that exceeding these limits results in a “lodging” use.  Allow some degree of off-site hosting for STR’s within multi-unit buildings.  Consider an alternative to Housing Replacement fees, such as an additional fee based on STR income. In either scenario, fees will support the City’s Housing Trust Fund. This additional fee needs to be determined by the City Council, and likely through a charter change.  Specifically enable hosts to short term rent their primary residence, no matter the residential building type. The standard for when the host is required to live on or be the owner of the property hosting an STR(s) emerged as one of the most important policy levers in determining how many STRs would be possible within the city. The Committee deliberated this issue on many occasions, specifically with regard to how permissive the policy should be, and what recourse the City had for changing the policy or curtailing STR use if too many housing units became STRs. As a result, staff provided a proposal for the Joint Committee’s consideration to shift much of the regulatory framework from the Comprehensive Development Ordinance (CDO) to Chapter 18: Minimum Housing Standards (Ch.18) of the City’s Code of Ordinances. This shift would preserve the ability to implement key policy objectives, but leaves a limited role for zoning regulation of STRs. Specifically, Ch. 18 can regulate the number of STRs permitted on a property or in a building as well as host- occupancy requirements where applicable. Ch.18 continues to be the tool to administer life safety standards and the annual rental registration process. Moving STR standards out of the CDO has several benefits, such as avoiding the onerous process of requiring new zoning permits each time a unit switches from long-term and short-term use. But most significantly, it addresses the Committee’s feeling that the policy may need to be adjusted in the future, and eliminates the concern that non-conforming STRs would be exempt from such changes. Because standards in Ch.18 apply at the time of each annual rental registration, any policy changes made since an STR’s last permit renewal would be applicable. Therefore, the limited role for regulating STR’s through the CDO includes allowing STR’s by-right where residential uses are permitted, and creating a definition that points to the specific STR regulations in Ch. 18. This amendment also condenses the definitions for several lodging types into one use/definition, and clarifies that they do not include STRs. Proposed Amendment Amendment Type Text Amendment Map Amendment Text & Map Amendment Purpose Statement The proposed regulatory framework is aimed at minimizing the potential for adverse impacts to the city’s housing stock, while balancing some flexibility for hosts to operate short term rentals. Together with amendments to Minimum Housing Standards in the City’s Code of Ordinances, the proposed amendment is intended to allow the short term rental of bedrooms within a dwelling, and the use of a host’s own dwelling occasionally as a short-term rental, with minimal burden to the host. Per-building caps are applied to whole unit short term rentals operated by off-site hosts so as to limit their proliferation. In an effort to balance the benefits to hosts with the preservation of long-term housing stock, short term rentals would generally be allowed wherever residential uses are allowed; however, in most scenarios, hosts must be a resident of the property. Proposed Amendments CDO Amendments With the shift of much of the regulatory framework to Ch. 18, only limited changes to the Burlington Comprehensive Development Ordinance are now proposed: 1. Amend Article 13 Definitions to define “short term rental”, modify “lodging” definitions Define short term rental as a type of dwelling unit and refer to standards in Ch.18. The STR definition reflects the state’s definition of an STR with regard to length of rental and refers to the Vermont rooms and meals tax. Additionally, the definitions of Hotel/Motel and Hostel are streamlined to a more general “Lodging” definition to reduce redundancy and inconsistencies in how various traditional lodging uses are permitted. 2. Add STRs as a “special residential use” to Appendix A- Use Table and in Article 14- Downtown Code This will establish that short term rentals are allowed anywhere that residential uses are allowed, and will refer to Ch. 18 for specific standards. Ch. 18 Minimum Housing Code Amendments The attached documents detail the related amendments to Ch. 18 Minimum Housing Standards. While Ch. 18 amendments are not normally the purview of the Planning Commission, they are reviewed by the City Council Ordinance Committee. Further, in this instance, the Joint Committee is recommending Ch.18 amendments because they resulted from the Committee’s charge from the City Council to create a regulatory framework for STRs. These amendments include: 1. Establish standards for the number and type of STRs permitted in a building, and when the host is required to be the owner/occupant of the property. Sets limits for the number of bedrooms rented in a Partial Unit STR, and limits for the number of Whole Unit STRs permitted in a building based on the number of units in the building. Additionally, requires host occupancy of the unit in which the STR is located except for in limited cases for STRs in multi-unit buildings of 3 or 4 units. 2. Establish minimum life safety standards for STRs, and requirements for annual rental registration. Defines a limited set of life safety standards for STRs, and additional information to be provided on rental registration applications for housing units to be used as STRs. Relationship to planBTV This following discussion of conformance with the goals and policies of planBTV is prepared in accordance with the provisions of 24 V.S.A. §4441(c). Compatibility with Proposed Future Land Use & Density The STR proposal is intended to protect existing housing from unlimited conversion to short term rental use. Data shows increasing numbers of short term rentals in recent years, largely at the expense of long term housing stock. This increase puts additional pressure on the city’s available housing and degree of affordability. The proposed measures will establish parameters for allowing short term rentals while limiting their adverse impacts on the city’s housing supply and affordability. Impact on Safe & Affordable Housing The proposal will have no impact on the intensity or density of future land use. It will; however, ensure that future short term rentals are compatible with the residential neighborhoods that so many of them occupy. Short term rentals will be allowed wherever residential uses are allowed. Per-building caps will prevent wholesale conversion of residential units into short term rentals. Planned Community Facilities This amendment has no impact on any planned community facilities.
