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. 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. Please raise your hand to be recognized to speak and the Chair will try to call on each participant in sequence. 3. Once recognized by the Chair, please identify yourself to the Commission. 4. 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 conduct business items. 5. Side conversations between audience members should be kept to an absolute minimum. The hallway outside the Community Room is available should people wish to chat more fully. 6. Please address the Chair. Please do not address other audience members or staff or presenters and please do not interrupt others when they are speaking. 7. Make every effort not to repeat the points made by others. 8. The Chair will make reasonable efforts to allow everyone who is interested in participating to speak once before speakers address the Commission for a second time. 9. 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 sway public opinion on the matter. 10. Comments may be submitted before, during or after the meeting to the Planning and Zoning Department. All written comments will be circulation 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. 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: Continue Review of Forested Habitat Block Applicability DATE: September 29, 2020 Special Planning Commission meeting Note: this memo has been updated from its original date of 9/22 to include staff recommendations for discussion. In March, the Commission had begun review of the applicability of Forested Habitat Blocks based on the Arrowwood Environmental Habitat Block Assessment and Ranking. The Commission elected to remove the following areas from applicability: • Areas within the City Center Form Based Codes District • Areas on pre-existing lots less than 1 acre in size built with a single-family home • Areas within 50’ of an existing building During the spring, staff worked with the consultants from Arrowwood Environmental as well as Jens Hilke from the Agency of Natural Resources to identify key “connectors” between habitat blocks. Those mapped connectors are included in the May 26th Environmental Protection Standards, and the rationale for their selection is discussed in the accompanying memo. At this meeting, Commissioners are invited and encouraged to review the remainder of the Forested Habitat Blocks identified by Arrowwood Environmental and consider whether any additional areas should be exempted from review under the LDRs. These could include areas where other City objectives / priorities may outweigh the presence of the Forested Habitat Block. We have recently added the City’s water & sewer infrastructure to the Interactive Map Viewer. In addition, the planned infrastructure (principally transportation) is available via the Comprehensive Plan (see page 203 for the map), and upon request could add it to the Map Viewer. If Commissioners would like to have any other information or data to assist with this evaluation, please let staff know. Staff recommendations: Staff recommends that the Commission discuss the following areas where forest blocks and planned transportation infrastructure intersect: • The southwestern intersection of Hinesburg Road and I-89, where the City’s Comprehensive Plan envisions a possible Exit 12B. This location is shown on the Official Map and as such would be reserved from private development unless abandoned by the City Council • The connection between Preserve Road in South Village and Upswept Lane in South Point. This connector is a planned roadway and recreation path connection between the neighborhoods, and 2 further would continue as a recreation path across the Underwood Property to Nowland Farm Road (as shown in the Underwood property Master Plan and included in the City’s Capital Improvement Plan). In considering this, the Commission may also wish to discuss the small forested area to the west of this connection. • More generally, The Commission may wish to examine the forested blocks that were among the lower-ranked. In doing so, staff would recommend considering their context in terms of both the built environment and also in terms of connectivity between habitat blocks. The Map Viewer has also been upgraded to include information on the percentage of habitat block (exclusive of hazards) on properties around the City. Under “other layers”, click on “percent of parcel area within Habitat Blocks (overlaps with hazard removed). If Commissioners are prepared to make decisions regarding any of these possible areas, staff would happily accept them. The item is not “critical path” at the moment, but as it relates relatively closely to the prior agenda item, Jessica and staff felt it would be a good time to discuss this. Staff would like to have the Commission’s full draft list in the next 1-2 meetings if not this evening, however, to help having a complete draft for Council and public review in October. 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: PUD applicability Draft; Initial outline of SEQ applicability DATE: September 29, 2020 Planning Commission meeting The Commission has previously, generally reviewed the applicability of Planned Unit Development types cross the City. Below is a table of proposed applicability (from your August 25th memo): PUD Type Allowable Zoning Districts Infill/ Redevelopment Applicable TND / NCD districts Conservation PUD All Zoning Districts where thresholds are exceeded (ie, a parcel contains more than 70% natural resources); R1, R2, SEQ-NR, SEQ-NRT, SEQ-VR, SEQ-VC; TND R1-PRD, R1-LV, R2, R4, R7, Lakeshore, Allen Rd, Swift St, C1-LR, R7-NC, SEQ NR, SEQ-NRT, SEQ-NRT, SEQ-VR, SEQ-VC NCD R12, All C1- Districts, C2, Allen Road, Swift St, R7-NC The table above is reflected in the attached maps [my apologies for the hand-drawn map; we will update this shortly with a GIS-based map]. Staff has also advanced the Commission’s discussed from 2019 regarding modifications to underlying zoning. This summer staff further refined this work to be as closely pertinent to the PUD work as possible. Staff will provide this in a mapped form at your next meeting for your review and consideration. The majority of these modifications are designed to better align types of uses and types/scales of buildings with the Comprehensive Plan. These will inform the applicable PUD also. For example, a TND in a higher- intensity underlying zoning district is proposed to be able to incorporate the underlying zoning district’s uses into the PUD, and would also likely “unlock” additional, larger building types than a TND in a lower-intensity district. Staff also draws the Commission’s attention to the Hill Farm and a couple of adjacent properties on the west side of Hinesburg Road immediately south of I-89. This land is presently zoned Industrial/Open Space. The 2016 Comprehensive Plan’s Future Land Use Map indicates that the property should be re-designated for a mixed-use area, with conservation in the western portion. These properties have been proposed to be eligible for a TND, NCD, and/or Conservation PUD (or some combination thereof). In order to facilitate this, the underlying zoning will need to change to a mixed-use district. Staff will present this with your meeting packet for next meeting. 2 The remainder of this memo was included in the PC’s 9/22 Memo on PUDs: Initial Staff thoughts on PUDs in the Southeast Quadrant (SEQ) and TDR applicability: Staff is continuing to develop how this portion of the regulations would operate. The Commission’s recent (and current) decisions will help to shape staff’s recommendations for how to integrate the specific elements of the SEQ and TDR standards into the updated Regulations. Below, to help with this week’s work on Environmental Protection Standards, is our current working outline: Current Standards: all properties in the SEQ have a base density of 1.2 units per acre. Through transfer of TDRs, receiving areas have a maximum density of 4 units or 8 units per acre. All subdivisions must be PUDs under the current regulations. PUD standards are contained within Article 9 and reference the Subdivision/General PUD standards of Article 15. Possible Future Standards: applicants exceeding the threshold for a PUD would be required to select a PUD type [replacing the existing Article 9 PUD standards]. Pending Commission review of applicability (later this month), these may be a Conservation PUD, a TND, an Infill TND, or a combination. • TND PUD: o Land within the NRP is excluded from being in a TND, but may be included in a Master Plan to allow for be an internal transfer of TDRs and connectivity of trails, working lands, etc. o Hazards and Level I Resources outside the NRP are removed from buildable area as with TNDs citywide o Base density remains 1.2 dwelling units per acre [Commission to discuss whether this includes or excludes Hazards] o All designated buildable areas must have a minimum of 4 units per acre, which must be designated at the Master Plan level. o TDRs may be used to acquire TDRs for all development above 1.2 dwelling units per acre within buildable area, up to the amount allowable via building types o If, in designating buildable areas, there is leftover land (due to TDRs not having been fully applied), remainder of land must either be designated for permanent conservation, or reserved for future use. Reserved areas must be indicated on the Master Plan and are removed from the land use allocations for the PUD until the Master Plan is amended. • Conservation PUD: standards apply per city-wide within the area outside the NRP. [Commission/staff to review whether to apply minimum density, and to determine whether NRP on the parcel should be factored in] 1. NRP Subdistrict amendment: Related to, but not specifically part of the work above, staff recommends the following adjustments to the NRP subdistrict to advance its objectives to foster land conservation: Current: the NRP subdistrict permits one home on parcels up to 15 acres in size, and 3 homes on parcels up to 100 acres in size Proposed: No change in dwelling unit total. Proposed modification to require establishment of a maximum building envelope for all homes (to provide the DRB with guidance on how large a home, lawn, etc. can be within the NRP), and to eliminate the requirement for each allowable dwelling unit to be a single family home (therefore allowing the 3 homes on a 15+ acre parcel to be in either a triplex or a duplex and a single family home).
