Minutes - Development Review Board - 04/18/2017
DEVELOPMENT REVIEW BOARD 18 APRIL 2017 The South Burlington Development Review Board held a regular meeting on Tuesday, 18 April 2017, at 7:00 p.m., in the Conference Room, City Hall, 575 Dorset Street. MEMBERS PRESENT: B. Miller, Chair; J. Smith, J. Wilking, M. Cota, F. Kochman, ALSO PRESENT: R. Belair, Administrative Officer; L. Britt, Development Review Planner; B. McKenney, K. & K. Boudreau, J. Painter, S. Ticehurst, P. Wells, M. O’Brien, D. Marshall, D. Cummings, E. Langfeldt, A. Gill 1. Directions on emergency evacuation procedures from conference room: Mr. Miller provided directions on emergency evacuation procedures. 2. Additions, deletions, or changes in order of agenda items: Item #6 was moved to item #5. 3. Comments & Questions from the public not related to the Agenda: No issues were raised. 4. Announcements: There were no announcements. 5. Conditional Use Application #CU-17-04 and Site Plan Review Application #SP‐17‐15 of Roman Catholic Diocese of Burlington – Rice Memorial High School to amend a previously approved plan for a 126,875 sq. ft. educational facility. The amendment consists of constructing a brick walkway to the adjacent property, 99 Proctor Avenue: Mr. Wells explained that the Diocese moved into new quarters in 2011 and noticed a lot of foot traffic (including mothers with strollers) between Rice H.S. and the Lund Home. There was concern because of the rough terrain. The Bishop suggested the walkway. It will be maintained in winter time. No issues were raised. Mr. Cota moved to close #CU-17-04 and #SP-17-15. Mr. Kochman seconded. Motion passed 5-0. 6. Continued Preliminary Plat Application #SD-16-37 of O’Brien Farm Road, LLC, for a planned unit development on 39.16 acres consisting of: 1) 64 single family dwellings, 2) 27 two-family dwellings, and 3) 14 lots, 255 Kennedy Drive: Mr. Langfeldt noted that at the February meeting the DRB had asked for additional information which they have now provided as follows: Re: Proposed Street Types: Mr. Langfeldt showed an image of the “new urban design street type.” There would be material and color change to distinguish the road from the pedestrian way. He showed photos of where this has been done. The streets are essentially “glorified driveways,” not through streets. Mr. Langfeldt said this will be safer because they are narrower and are all dead end streets. The target speed is 15 mph. Mr. Kochman asked if this is authorized under form based code. Mr. Belair said it is. Mr. Kochman said he can see a dangerous potential. Mr. Gill then showed a chart indicating the average projected time between vehicles. Mr. Wilking asked if this design is recommended other than in form based code. Mr. Belair said it is not. Ms. Britt noted that both staff and Public Works support this. Phasing/Construction of Road “B”: Mr. Gill said the existing Kennedy Drive and Hinesburg Road access will serve until Road “B” is constructed (when the large new building is built). He showed maps indicating that level of service remains unchanged and there is no increase in queueing. Mr. Kochman felt the DRB shouldn’t rely on level of service, and they are not obliged to have a “D” level of service get a little bit worse but not enough to get to “E.” He added that this is desirable development with rotten traffic conditions, but people need a place to live. Phasing Plan Update: Mr. Langfeldt showed the phasing plan and noted it is tied to bonding requirements. He also showed the constructing schedule. He expressed concern with differing interpretations of Master Plan language. Mr. Miller said unambiguous language is needed and advised the applicant to work with staff to achieve that. Mr. Wilking said he had no issue with phasing the trails. Ms. Britt said the Master Plan can be amended or the waiver request can be removed from the Master Plan. Mr. Gill asked if they can join Final Plat with revision of the Master Plan. Mr. Belair said they can. Height Waivers: Mr. Gill said they calculated grades on all lots and the height waiver request. He showed a table of heights per unit. They are requesting waivers of 2 feet above those numbers. Mr. Miller asked if the DRB can grant that request. Mr. Belair said they can. He suggested revising the table to include the 2 feet so the DRB can see the maximum heights. Neighbor Concerns: Mr. Langfeldt noted there are 2 neighbors concerned with the development, and there was a meeting with them. As a result of that meeting, some additional screening is proposed. Mr. Kochman asked if the city requested an increase in density. Mr. Langfeldt said that is not what they said. They are trying to reach the underlying density. Mr. Cota said if the city didn’t want that density, it wouldn’t be in the regulations. Mr. Kochman asked if there are criteria for preserving wildlife. Ms. Britt said she has seen references to connections and preserving habitat. She didn’t know if “wildlife corridors” are specifically mentioned. Mr. Miller asked if an existing wildlife area precludes development. Mr. Belair said it does not. Mr. Gill said that is dealt with at Act 250. Mr. Kochman noted there is a priority for development here, but he didn’t want to violate a requirement, if there is one. Ms. Britt said staff doesn’t yet have comments from Public Works or the Arborist, but if the applicant has done everything asked for, it should be OK. Mr. Gill showed a plan indicating the additional plantings. Trail Connection to Old Farm Road: Mr. Gill said the Bike/Ped Committee wants a woodchip path. They will put it in, if the DRB feels it is necessary. Board members said they want the path. Mr. Gill then raised the question of permit duration. He noted the project will take at least 5-6 years to complete. Mr. Belair said in the past, the board has given 5 years with a one-year extension option. Mr. Langfeldt said they would like 5+1+1. Mr. Wilking said he had no issue with multiple one-year extensions. Mr. Gill suggested 7 years with 2 one-year extensions. Members then discussed whether to close the application tonight. Mr. Belair said staff can prepare a decision without closing. He felt that the 45-day requirement put staff in a tight box. Ms. Britt felt there could be a draft of the decision for discussion at the next meeting. Mr. Miller pledged to get it done as quickly as possible. Mr. Cota moved to continue #SD-16-37 to 2 May 2017. Mr. Wilking seconded. Motion passed 5-0. 7. Continued Preliminary and Final Plat Application #SD-17-06 of Donald R. Cummings for a planned unit development consisting of two lots, each developed with a single family dwelling. The project consists of: 1) subdividing the 1.16 acre parcel into two parcels of 0.6 acres (lot #1) and 0.56 acres (lot #2), and 2) relocating the zoning district boundary between the R-1 and R-2 zoning districts in conjunction with the planned unit development, 1811 Spear Street & 25 Harbor Ridge Road: Mr. Marshall noted they are combining 2 properties to allow for redistribution of density. He showed a plan with the 2 parcels of interest. The applicant worked with staff to transfer development density from one lot to the other. Mr. Marshall indicated where the densities would go. The applicant met with the Fire Chief and Marshall regarding access. They also have discussed stormwater management and drainage improvements with the Stormwater staff. Mr. Marshall showed the utility plan with the stormwater mitigation plan. Parts of the drainage way in the right-of-way will be paved as requested by Public Works. Roof runoff from the house on lot #2 would be directed to the retention area. Ms. Smith asked about deed restrictions regarding heights. Mr. Cummings said there are no restrictions in this area. His intention was to enhance views and he took down some trees to improve neighbors’ views. The plan is for the new house to be 5 feet taller than the existing house. There will be deed restrictions, but they prefer these not be part of the DRB review. The Board was OK with this. Mr. Cota moved to close #SD-17-06. Mr. Kochman seconded. Motion passed 5-0. 8. Minutes of 21 March and 4 April 2017: Mr. Cota moved to approve the Minutes of 21 March and 4 April 2017 as presented. Ms. Smith seconded. Motion passed 5-0. 9. Other Business: Mr. Belair presented a request for a 6-month extension to #SD-16-30 of Mary Jo Capotrio. Mr. Cota moved to grant the 6-month extension to #SD-16-30 as presented. Mr. Wilking seconded. Motion passed 5-0. As there was no further business to come before the Board, the meeting was adjourned by common consent at 8:36 p.m. , Clerk _________5/2/2017____________________________ Date Published by ClerkBase ©2019 by Clerkbase.

The amendment consists of constructing a brick walkway to the adjacent property, 99 Proctor Avenue. The Development Review Board held a public hearing on April 18, 2017. The applicant was represented by _____________. Based on the plans and materials contained in the document file for this application, the Development Review Board finds, concludes, and decides the following: FINDINGS OF FACT 1. The applicant, Roman Catholic Diocese of Burlington—Rice Memorial High School, seeks to amend a previously approved plan for a 126,875 sq. ft. educational facility. The amendment consists of constructing a brick walkway to the adjacent property, 99 Proctor Avenue. 2. The owner of record of the subject property is Roman Catholic Diocese of Burlington, Inc. 3. The applications were received on March 7, 2017. 4. The property lies within the Residential 4 Zoning District. 5. The plan submitted consists of one (1) page titled “Rice Memorial H.S. South Burlington, Vermont,” prepared by Forcier Consulting Engineers, PC, dated 4/29/2014 and revised 5/24/2016. CONDITIONAL USE STANDARDS An educational use is allowed in the Residential 4 Zoning District only as a conditional use and hence this application for a brick walkway must be reviewed under the conditional use standards. Pursuant to Section 14.10(E) of the LDRs, the proposed conditional use shall not result in an undue adverse effect on any of the following: (1) The capacity of existing or planned community facilities. (2) The character of the area affected, as defined by the purpose or purposes of the zoning district within which the project is located, and specifically stated policies and standards of the municipal plan. (3) Traffic on roads and highways in the vicinity. #CU-17-04 & #SP-17-15 2 (4) Bylaws and ordinances then in effect. (5) Utilization of renewable energy resources. The Board finds that the proposed brick walkway will not result in an undue adverse effect on any of the above criteria. SITE PLAN REVIEW STANDARDS Section 14 of the Land Development Regulations establish the following general review standards for site plan applications: A. Relationship of Proposed Development to the City of South Burlington Comprehensive Plan. Due attention by the applicant should be given to the goals and objectives and the stated land use policies for the City of South Burlington as set forth in the Comprehensive Plan. The Board finds the project will have no impact on the Comprehensive Plan. B. Relationship of Proposed Structures to the Site. 1) The site shall be planned to accomplish a desirable transition from structure to site, from structure to structure, and to provide for adequate planting, safe pedestrian movement, and adequate parking areas. 2) Parking 3) Without restricting the permissible limits of the applicable zoning district, the height and scale of each building shall be compatible with its site and existing or anticipated adjoining buildings. No structures are being proposed or changes to parking. C. Relationship of Structure and Site to Adjoining Area 1) The Development Review Board shall encourage the use of a combination of common materials and architectural characteristics (e.g. rhythm, color, texture, form or detailing), landscaping, buffers, screens, and visual interruptions to create attractive transitions between buildings of different architectural styles. 2) Proposed structures shall be related harmoniously to themselves, the terrain and to existing buildings and roads in the vicinity that have a visual relationship to the proposed structures. No structures are being proposed. Specific Review Standards A. Access to abutting properties. The reservation of land may be required on any lot for provision of access to abutting properties whenever such access is deemed necessary to reduce curb cuts onto an arterial or collector street, to provide additional access for emergency or other purposes, or to improve general access and circulation in the area. #CU-17-04 & #SP-17-15 3 The proposed walkway will create a connection between the school and a neighboring property. The Board finds that no reservation of land is necessary. B. Utility Services. Electric, telephone and other wire-served utility lines and service connections shall be underground insofar as feasible and subject to state public utilities regulations. Any utility installations remaining above ground shall be located so as to have a harmonious relation to neighboring properties and to the site. No new utilities are proposed. C. Disposal of Wastes. All dumpsters and other facilities to handle solid waste, including compliance with any recycling or other requirements, shall be accessible, secure and properly screened with opaque fencing to ensure that trash and debris do not escape the enclosure(s). Small receptacles intended for use by households or the public (i.e., non-dumpster, non-large drum) shall not be required to be fenced or screened. No new dumpsters, recycling, or composting areas are proposed. D. Landscaping and Screening Requirements. See Article 13, Section 13.06 Landscaping, Screening, and Street Trees. No new landscaping is proposed or required.

The Board began hearing about this application on March 7, 2017 and identified a few issues on which they wanted more information. The applicant prepared a presentation for the April 18, 2017 meeting which addresses most of these issues. Staff provides the following comments which address some issues raised on March 7th as well as some of the new materials provided by the applicant. 1. The applicant has submitted tables for the height waivers requested and staff has provided the applicant with feedback on the formatting of these tables. Staff is supportive of the height waiver requests. 2. Staff continues to think the condition of the master plan regarding the construction of the pedestrian paths requires those paths to be built during what is identified by the applicant as Phase 1A of the proposed project. a. The condition reads: “If off-road pedestrian paths are developed during the first phase of the project construction then the requirements of Section 15.12(M)(5) will not [be] applicable within the Master Plan area.” b. The applicant has listed on their plans “Phase 1A,” which staff thinks makes it identifiable as the “first phase” of the project as outlined in the master plan condition: “1” is the first positive whole number and “A” is the first letter of the alphabet. c. Staff has read the applicant’s concerns regarding this matter; however, staff is bound to read the decision in its plainest meaning and minimize any interpretation, which staff has done. d. Staff considers that to read the condition the way the applicant suggests would mean that the applicant could build all the housing units proposed as part of Phase 1A through Phase 5 before putting in any pedestrian paths, potentially leaving hundreds of people without these additional pedestrian connections for many years. e. If the Board agrees with staff on the meaning of the master plan condition then staff recommends the following possible solutions for the applicant: i. Seek to amend the master plan to either remove the waiver of 15.12(M)(5) or clarify the meaning of the waiver. ii. If the waiver is removed from the master plan decision then the applicant could instead seek that same waiver during preliminary or final plat. 2 3. The applicant updated the plans in response to comments from the Stormwater Section. Staff has not yet received new comments from Stormwater. 4. Staff recommends that, if the Board decides at the close of the hearing on April 18th that it is ready to enter deliberations, the hearing be left open and continued to a future date, so that if new questions arise during deliberations the Board is able to receive new information without having to re-open the hearing.

Issued Permit Duration Request.12. Conclusion: Requested Findings from Development Review Board2 Proposed Street Types •During initial hearings the Board expressed some concern over having a sidewalk flush with a traveled way. •Applicant is providing information that is the basis for this proposed design, including the New Urban Street manual, which is the main driver. •Applicant believes strongly that this design is a great benefit to the community, creating a safe pedestrian prioritized roadway for this neighborhood. •Many cities and towns use this new urban design manual, to create similar environments where the roadway is shared, and traffic is subordinate to pedestrians. 3 New City Lane Street TypeBased on Nat. Assoc. of City Transportation Officials DesignsProposed Street New Urban Design Street TypeApplicant has adapted New Urban Design street‐type to meet City Fire Safety and Public Works Requirements.4 Excerpts: New Urban Design Residential Shared Street 5 Shared Street Examples from New Urban Design Manual6 Proposed Shared Street Rendering7 City Zoning Currently Has Provisions for Lanes; Applicant is Proposing a 20’ LaneO’Brien Brothers has created a hybrid version of this lane, designed for the same purpose, but wide enough to accommodate emergency vehicles, and remove the necessity for another road!8 Bike and Pedestrian Committee Comments •As stated in the excerpt from a February 28themail to the Development Review Board from the South Burlington Bicycle and Pedestrian Committee, the committee “endorses” the grade level sidewalk proposed.•Applicant intends to use two different materials, cement and asphalt, which will result in two colors, as recommended, and shown here (at left). Applicant is also willing to provide a stripe of paint between the sidewalk and road, if requested. This stripe would be a bright color, like yellow or white.9 Shared Street Use (Number of Trips) and Potential Occurrences of Two‐Way Traffic•In response to safety concerns regarding when two cars going opposite directions might pass each other, we looked at how often this might occur.•Applicant’s traffic consultant has analyzed the frequency of trips, and potential occurrence of two cars passing each other (one coming and one going) on each of the proposed shared streets. •Analysis shows that during the AM/PM Peak hours, the busiest road sees one car every 3.5 minutes. •The average time between cars on all three roads (AM and PM Peak Hours Only) is one car (either coming or going) every 5.7 minutes. Off peak hours would no doubt be lower •Statistical models predicting the occurrence of two cars meeting show ZEROoccurrence. •The chance is so small that modeling did not quantify it. •An excerpt detailing report findings follows:10 Shared Street Use (Number of Trips) and Potential Occurrences of Two‐Way Traffic11 Traffic Impact Analysis; Proposed Phasing and Construction of Road B•At the February 7thmeeting the board expressed some concern with the proposed timing of constructing New City Road B and the light on Kennedy Drive. •Applicant has provided a summary memo detailing the findings of a traffic impact study, that supports this phasing will not have any undue, or even, nominal impact on the existing traffic conditions at impacted intersections.•Applicant requests that the Board find at the preliminary plat level that the traffic study is accepted, and that the phasing proposed is accepted. •If the Board will require third party review of the Traffic Study, applicant requests that such review be invoked now for a specific scope of work within the overall traffic study, such that it can be completed in a timely manner.” •The following slides show the impact of the proposed 118 unit project (without Road B) on relevant adjacent intersections. 12 Traffic Impact Analysis; Impact of Construction of 118 Units w/out Road B Kennedy Intersection •Applicant has analyzed the impacts of the entire 118 unit development as proposed on surrounding intersections.

Construction sequencing phases; andb. Amenity Construction timing. •The plans are presented on the following sheets.21 Home Farm Phase I Construction Sequence22 Home Farm Phase I Amenity Construction Timing 23 Recreation and Parks Committee Review •Applicant met with the Recreation committee on March 20th, 2017.•The Committee unanimously endorsed the Applicant’s proposed amenities.•The Committee unanimously endorsed the Applicant’s proposed construction phasing. •The Committee thanked the Applicant for their willingness to install the entire park and all pedestrian improvements so early in the project, and prior to the majority of the units allowed in the Master Plan being built. •Applicant pointed out that all pedestrian and recreation amenities are proposed to be builtat completion of 118 units, only 25% of the total units contemplated within the Master Plan. 24 Construction of Pedestrian Paths•As outlined in the construction phasing plans, pedestrian paths are proposed to be built when the construction of homes and roads immediately around those paths is complete. •This is the plan approved and unanimously endorsed by the Recreation and Parks Committee. •City Staff has raised an issue with this approach in their comments. The issue pertains to an interpretation of a finding of the Master Plan permit issued by the Board. •Applicant does not see any contradiction between what is proposed, and the language of the Master Plan. 25 Construction of Pedestrian Paths•Specifically, the City States in their comments from 03 07 17: •Applicant does not believe that the proposed phasing plan is in any way non‐compliant with the approved Master Plan. The approved Master Plan states: •Applicant considers the current application for 118 homes to be the first phase of project development. •Applicant’s interpretation is also consistent with all previous applications, submissions and discussions that Applicant has had with the Board, where it has clearly stated that the pedestrian amenities would be constructed concurrent to the phases of infrastructure and unit construction for these single family and duplex homes, so as to provide an orderly, logical and above all else SAFE site for construction personnel and the general public.26 Construction of Pedestrian Paths•Staff is suggesting that the “first phase of development” contemplated in the Master Plan permit is the first construction phase (Phase 1A) of the Project. This would mean that all pedestrian trails planned must be built when New City Road C is constructed. •This would result in trails being built in woods, and across a property that still needs to be logged and cleared for construction, where significant roads and 118 homes will be constructed .•This would result in a circular path through 2 acres of woods being opened to the public at Phase 1A, and then when Applicant constructs Phase 2, 2 acres being logged and cleared, and a stormwater system being built in the middle of the trail, only inches from the trail in many points.•Applicant plans to travel from active zones in the south of the parcel to material stockpiles hidden in the north of the parcel throughout construction on haul roads that will be formed, using off‐road dump vehicles. These large vehicles are not designed for safe use in pedestrian areas. Having city residents and the general public crossing haul roads hiking with pets in this environment is simply unsafe.•In most cases with projects this large, communities seek to enforce construction perimeters to keep pedestrians outside of construction zones and safe. Staff is seemingly requiring that we invite people inside construction zones, which is the opposite of normal. There is a major liability issue if this recommendation is followed.•We believe the result of this interpretation is illogical, and therefore the Board will agree that the “first phase of development,” is the entirety of the 118 units currently proposed. And therefore the phasing of trail construction proposed is compliant with the MP.•The Applicant notes this application is the firstand only applicationfiled under the Master Plan. The Applicant also notes that the cover sheet and all of the plans filed with the original application on December 23, 2016 said “Obrien Home Farm Phase I.”•Applicant only removed the “Phase I” title from all of the plans at the request of Staff, who said it was confusing to call the project Phase I, while also calling the construction phases, Phase I, Phase II, etc. 27 Hypothetical Project Map if City Staff Recommendation is FollowedThe Parkdoes not yet exist. Thisentire area needs to be cleared for stormwater treatment. The trails go no‐where, the entire central trail system is not even connected to a public way, and you would need to walk through unmarked woods and active construction to even get to the start of the trail.28 Height Waiver Request •As requested by staff, Applicant is providing a table indicating the maximum proposed height of each of the 118 units proposed. •The height is calculated based on the pre‐infrastructure construction grading. •As indicated at the March 7thmeeting. This results in standard 2‐story homes (in some cases), needing height waivers.•Applicant wishes to reiterate that the waivers requested are only seeking to permit the construction of the homes and architecture shown in Project plans. Despite some of the large numbers requested. •Lastly, Applicant is requesting to add 2’to each number requested, simply because with the scale of this project, it is difficult for us to be accurate within inches, and we would hate to create a situation where a specific site condition now‐unknown changes the calculations causing delays during construction. •Regardless of the height waivers issued, in the end you will have the reasonably sized single family and duplex homes we are showing in our plans. 29 Height Waiver Request•This figure illustrates why using pre‐existing grading can result in the need for height waivers in single family homes•Purple is the existing grade. •Red is the finished grade after infrastructure work. •The orange line is the height measured from pre‐existing grade. •The green line is the height measured after infrastructure construction. Which is the dimension that actually reflects the true height of the buildings.30 Height Waiver Request•Applicant is requesting a 2’ contingency, simply because knowing the exact ups and downs of the purple line for the entire 40 acre site is difficult, and we want to ensure there are no issues when individual permits are filed. An unknown minor undulation like the BLUE line could create a problem without the 2’ contingency.31 Sample Height Waiver Table for Review •Yellow highlighted unit numbers require a waiver. •The waiver requested is the building height as calculated and shown, plus an additional two feet. •In some instances the number of stories requested also requires a waiver, due to the basement level of the home being exposed on the street‐side. •These instances are also highlighted in yellow. 32 Sample Height Waiver Table for Review •As outlined in the graph, the Board should note the wide discrepancy in “height” as calculated using the pre‐existing grades of this site. •The structure of Unit 49 is actually taller than unit 105/106 in terms of its actual constructed height above the foundation.•However, Unit 49 is anticipated to be less than 28 feet tall, and unit 105/106 is expected to be nearly 37 feet tall. •This variance is not related to unit sizes, which are all similar.•This goes both ways, unit 38 is only 11 feet tall, measured by these standards. Despite the building being nearly 26 feet from foundation to roof.33 Digital Renderings of Proposed Homes•Before granting a height waiver it must be demonstrated to the Board that the proposed waiver will not: “detract from scenic views from adjacent public roadways. •The two adjacent existing public roadways from which the project will be seen are Eldredge Street and Old Farm Road. •Digital renderings of the proposed development are provided to show that no scenic views will be impacted, and to demonstrate the size and scale of the project. •In fact, there are no scenic views from Old Farm Road or Eldredge Street, in the area where the project is proposed. And therefore regardless of height, no scenic views will be impacted. •Given that no scenic views currently exist, and that the size and scale of the proposed units is in keeping with the surrounding neighborhoods as shown, we hope the Board will grant the height waivers requested. 34 View From Old Farm Road 35 View From Old Farm Road 36 View From Old Farm Road 37 View From Eldredge Toward Park38 View From Eldredge Toward Park39 View From Eldredge Toward Park40 View From Eldredge Toward Old Farm41 View From Eldredge Toward Old Farm42 View From Eldredge Toward Old Farm43 Neighbor Concerns; Site Conditions and Screening Proposed•At the last hearing our neighbors on Old Farm Road raised some concerns with the impacts of the Project on their views and property. •In response to these concerns, Applicant has carefully reviewed the areas in question. •This review included marking the property line to fully understand where the proposed project is located, in relationship to existing homes. •This review also included an analysis of the slopes in the area, to determine areas where screening would be appropriate. •Due to significant grade changes and existing dense wooded buffers, screening is only appropriate in select locations. 44 Neighbor Concerns; Site Conditions and Screening Proposed•A dense wooded buffer exists along this property line in the red box, and is paired with a significant drop in grade.•Subsequent site sections illustrate this grade change. 45 Neighbor Concerns; Site Conditions and Screening Proposed300’ From Existing Voldman Residence to New HomeApprox. 125’ From Pool To Existing ResidencePool is used only during months when Existing Dense Vegetation Downgradient is in Bloom. Line of Site from residence would look over roof tops, if they could be seen through existing woods, which is unlikely. 46 Neighbor Concerns; Site Conditions and Screening Proposed300 feet from Existing Weiner Residence to Unit 22 Line of Site from residence would look over roof tops, if they could be seen through existing woods, which is unlikely. 47 Neighbor Concerns; Site Conditions and Screening ProposedUnits proposed on New City Road F do have line of site to the existing residences Unit 34 is approximately 130 Feet from the Existing Weiner Residence, and is located on the same plane. While significant mature trees exist on the Weiner lot, they are deciduous, and will provide screening only in summer. Given this, Applicant is providing a hedgerow of evergreen screening, now shown on the landscape plans and in this site section. Applicant notes that the southerly neighbor to this residence is likely about 70 feet from the Weiner residence or about ½ of the distance to the proposed new home. The proximity of homes proposed seems in keeping with current surroundings. 48 Neighbor Impacts Video Links 4Videos from the approximate locations shown in red are linked to the shapes.

However, given the pool location, and the request of the neighbor for additional screening. Applicant is providing evergreen screening at the property line. •Applicant is also providing screening adjacent to unit 34, where the proposed units are on the same plane as the Weiner residence. •Applicant is not proposing any screening adjacent to Units 22, 23 or 33. As shown in the videos, there is an incredibly steep slope here, densely wooded with 50’+ tall evergreen trees. Given this, no screening is necessary. •The amended landscape plan is shown on the next page. 55 Neighbor Concerns, Amended Landscape Plan New evergreen screening shown in red circles56 Landscape Plan Arborist Comments•The City Arborist provided comments in blue. •All comments have been adopted and included in amended landscaping plans. •Applicant is seeking approval of landscape plans as part of preliminary plat, to assist in expediting bidding and eventual bonding.57 Landscape Plan Changes to Accommodate Rear Yard Setback Waivers•At the last hearing we discussed re‐orienting a portion of the park walking trail behind units 63‐68, so the board could grant the requested rear setback waiver. This has been done.•We also discussed adding some additional screening behind units 95 and 96. This is also done. •Before and after screenshots of relevant plans are provided on subsequent slides. 58 Landscape Plan Changes to Accommodate Rear Yard Setback WaiversBeforeAfter 59 Landscape Plan Changes to Accommodate Rear Yard Setback WaiversBeforeAfter 60 Stormwater Utility Comments and Responses •Krebs and Lansing has provided a memo addressing all of the items raised in these comments. •We believe that these answers will be satisfactory to the stormwater utility. •We await their feedback on responses provided. 61 Stormwater Utility Comments and Responses 62 Stormwater Utility Comments and Responses 63 Trail Connection To Old Farm Road•Applicant has confirmed with the bike and pedestrian committee, that they are requesting Applicant construct a wood‐chip path that connects the end of New City Road A with Old Farm Road. •Applicant suggests that this connection is not needed, and that it will facilitate pedestrian traffic to Old Farm Road where there is no sidewalk, or pedestrian infrastructure to safely convey them anywhere else. •Applicant will leave this issue to the Board to decide, and will either construct the wood‐chip path as conditioned in permit approvals or not. 64 Issued Permit Duration Request•Further to Applicant’s submission, applicant wishes to confirm if there is a time limit placed on the findings issued at preliminary and final plat. •Applicant is committed to construction of the entire project proposed, but hopes the Board understands this could take more than five years to complete. •Applicant requests that any decisions be written such that the Applicant has sufficient time to complete the project, and such that any extension requests required can be approved administratively if possible, to expedite any needed extensions.65 Conclusion and Requested Findings•At this point the Applicant believes we have addressed all of the questions and concerns raised by the Board and Staff. •In deciding on this Preliminary Plat, the Applicant requests that the board be as conclusive as possible with regard to: •Unit locations, unit counts and spacing: Applicant must produce extremely complicated erosion control plans, boundary surveys (for all 118 footprint lots), and other engineering plans for Final Plat submission. These plans will be incredibly difficult to alter, and therefore as much certainty as can be provided with regard to the items that will greatly impact this future work is appreciated. Additionally Applicant must estimate the cost of all infrastructure work, which is greatly affected by moving units, changes to roads, etc. •Waivers Requested: Applicant hopes the board can provide conclusive findings for all waivers requested, such that the Applicant can make adjustments to the plans and proceed to final plat with assurance that these details will not change. This is again tied closely to the work required to produce the plans and documents needed at Final Plat. 66 Conclusion and Requested Findings•Traffic Study: Applicant is requesting the Board make findings on the traffic study provided, including the proposed phasing. This is an intricate part of the project that we hope can be confirmed at this time. We would like to avoid a potential delay in the final plat proceedings to coordinate third party review. If additional study will be required by the Board (despite the supported conclusions presented and reviewed by the City engineer) we would request the board do so now so we can get started. •Project Phasing: Applicant is required to produce construction cost estimates for final plat, which must be produced by construction phase. Given this, we request the proposed phasing plan be approved, such that all of this work does not need to be re‐done, should that phasing be changed. •Landscaping Plan: We request the board find the landscaping plan is suitable, such that we can finalize the plans, and begin work on a strategy for bonding the plans and constructing them. •Permit Duration: Applicant believes that the construction of this project could take upwards of five years. Given this, we ask that any decision by the Board allow the applicant sufficient time to build and sell the project, without being required to seek extensions, or continue to come before the board. If this is a component of the preliminary plat findings, we request it be in line with the project timelines. 67 Conclusion and Requested Findings•We remain excited about this project, and the opportunity to create this neighborhood in South Burlington. •Thank you to the Board and Staff for your continued expeditious review. •We look forward to moving on to Final Plat this summer.68 Lamoureux & Dickinson Page 1 Consulting Engineers, Inc. TECHNICAL MEMORANDUM Project: O’Brien Home Farm Date: March 20, 2017 From: Roger Dickinson, PE, PTOE Subject: Requested Supplemental Information related to Traffic Impacts Below are outlined our response to questions and comments at recent DRB hearings for the above Project: Eldredge Street Capacity without New City Road ‘B’ access onto Kennedy Drive An analysis of future traffic conditions without the New City Road ‘B’ / Kennedy Drive access was included in the August 8, 2016 Traffic Impact Analysis for this Project. (top of pg 14 and Table 4). It is easily overlooked, however. With this Project being constructed in discrete phases, there will be a time when Eldredge Street will provide the only means of access to this Project via its existing intersections with Hinesburg Rd and Kennedy Drive. It is presently anticipated that the construction phasing will begin with construction of the residential units in Zone 1, followed by residential units in Zones 3 and 6. Zones 3 and 6 will be served by New City Roads ‘A’ and ‘E’, respectively. Both will ultimately loop to connect with each other and with New City Road ‘B’ in Zones 2A and 2B. The proposed residential units in Zones 1, 3 and 6 include: Table 1 - Proposed Residential Units Residential Unit Type Zone Total Units 1 3 6 Single-Family 28 -- 36 64 Multi-Family -- 44 10 54 Total 28 44 46 118 Extension of New City Road ‘B’ through Zone 2A, and construction of the new City Road ‘B’ / Kennedy Drive intersection, will be done coincidental with the proposed commercial and residential construction in Zones 2A and 2B. The timing of when construction in those zones might start is uncertain. For the purpose of this analysis, however, construction in Zone 2 is presumed to follow completion of the proposed residential units in Zones 1, 3 and 6. The peak hour trip generation of Zones 1, 3 and 6 is shown in Table 2. Figures 1 and 2 show the estimated directional distributions of the additional morning and afternoon peak hour trips that will be generated by Zones 1, 3 and 6 using only Eldredge St for access.

New City Roads ‘C’, ‘D’ and ‘F’ - One Vehicle at a Time Statistical Analysis New City Roads ‘C’, ‘D’ and ‘F’ are cul-de-sacs serving a relatively low number of single family residences. It is proposed that these roads be constructed as narrow (15 ft wide) streets with a concrete sidewalk immediately adjacent. This raised the question of what the probability would be of a vehicle having to wait while another vehicle travels the street in the opposite direction. The probability of one or more vehicles being delayed because the street was being used by another vehicle was calculated by using a computer language known as General Purpose Simulation System (GPSS). The simulations randomly (using the negative exponential distribution) generate vehicles using morning and afternoon peak hour trip rates. Using a first-come first-serve model, a vehicle occupies the street for the amount of time that it would take to travel the entire length of the street at 15 mph. No other vehicle can enter while the street is occupied. Any vehicles that arrive while the street is occupied are held in a queue, and the resulting number of occurrences and delays tabulated. Each simulation consisted of ten runs in order to provide more reliable data. Table 4 presents the results of the simulations. Table 4 - One Vehicle at a Time Statistical Analysis Street Length Travel Time Peak Hour # Vehicles per Hour Avg. Time Between Vehicles # Times A Vehicle Waited Total Delay Time New City Road ‘C’ 350’ 16 sec. AM 8 7.5 min. 0 0 sec. PM 11 5.5 min. 0 0 sec. New City Road ‘D’ 450’ 20 sec. AM 13 4.6 min. 0 0 sec.

The above results indicate that the occurrences of a vehicle being delayed from using New City Roads ‘C’, ‘D’ and ‘F’ while another vehicle travels the street in the opposite direction will be very infrequent.

Re: O’Brien Home Farm ‐ South Burlington Stormwater Section Comments We offer the following line item response to the review comments provided by David Wheeler of the City of South Burlington Stormwater Section. 1. This project is located in both the Potash Brook and watershed. This watershed is listed as stormwater impaired by the State of Vermont Department of Environmental Conservation (DEC). Also, the project proposes to create greater than 1 acre of impervious area and disturb greater than 1 acre of land. It will therefore require a stormwater permit and construction permit from the Vermont DEC Stormwater Division. The applicant should acquire these permits before starting construction. The project will be applying for both an Individual Stormwater Discharge Permit and either an Individual Construction Stormwater Permit or coverage under General Permit 3‐9020. These applications will be filed with the State of Vermont Stormwater Section after we are farther along the local permitting process to ensure the design of the stormwater management, treatment and collection system is presented consistently to both the City and State. 2. The project proposes to impact class 2 wetlands and their buffer. These impacts are only allowed in conjunction with issuance of a wetlands permit by the Vermont DEC. There are no actual class 2 wetland impacts proposed. We presume the buffer impacts referenced are in regards to the outlet pipe from Stormwater Pond B. These type of impacts are typically allowed, but will require a permit from the Wetlands Division. We have begun the process of obtaining a Wetlands Permit for these impacts. 3. As the project proposes to create more than one‐half acre or more of impervious surface, the project is subject to the requirements of section 12.03 of the LDRs. O’Brien Home Farm Response to Stormwater Section Comments March 24, 2017 2 With the exception of the items noted in these comments, we believe the stormwater design is in accordance with section 12.03 of the LDRs. We will continue to work with Stormwater Section and DPW staff to ensure compliance with all applicable regulations. 4. The applicant should confirm that requirements in Section 12.03(C)(1) are met and that the Water Quality Volume is infiltrated using Low Impact Development (LID). The stormwater management system proposes several meet these requirements. The majority of the project flows towards Infiltration Basin “A”. The infiltration basin will treat and infiltrate runoff from approximately 24 acres of project area, including nearly 8 acres of impervious surface. After meeting with David Wheeler, we identified additional areas of the project that are suitable for infiltration. The first two hundred feet of Road A will drain towards the existing Eldredge Street stormwater system. To meet City infiltration requirements, a stormwater collection cross pipe under Road A will be designed as flat perforated pipe (infiltration trench), to facilitate infiltration of the water quality volume. Similarly, stormwater collection cross pipes under Road B will be designed as flat perforated pipe (infiltration trenches) to facilitate infiltration of the water quality volume. These changes will be added to the design prior to Final Plan. Other areas of the project, such as Roads C, D, and F, are unable to meet standards for infiltration due to the presence of high seasonal groundwater or ledge. These conditions have been documented via soil borings. Water quality in these areas will be achieved via the use of grassed channels and permanent pools in the ponds. 5. The applicant should confirm that requirements in Section 12.03(C)(2) are met and that peak runoff rates are not increased during the 1 year storm event. The use of Micropool Extended Detention Ponds, Wet Ponds, Grass Channels, Infiltration Trenches, and an Infiltration Basin will ensure that post development peak flows are maintained at or below pre development levels. HydroCAD stormwater modeling calculations will be provided with the Final Plan submittal. 6. The applicant is required to submit the additional information outlined in Section 12.03(D), so that compliance with the City’s Stormwater Management Standards can be evaluated. Due to the level of detail and sheer volume of calculations required, we are requesting to submit this information at “final” rather than preliminary. This will prevent needless reproduction of work necessitated by minor changes to the design, while eliminating multiple reviews by City Stormwater staff. HydroCAD stormwater modeling calculation, as well as supporting forms, tables, spreadsheets, and plans, will be provided with the Final Plan submittal. 7. Storm drains proposed to be taken over by the City will require a 20’ easement, centered on pipe, free of structures or obstructions. As shown, some of the storm drains are less than 10’ from building foundations. O’Brien Home Farm Response to Stormwater Section Comments March 24, 2017 3 We have worked with Public Works staff to identify an acceptable easement. For the final plan application, Units 97‐118 will be adjusted slightly to enable a 20’ easement between Units 110 and 111. We have presented the attached sketch entitled “Proposed Utility Easement” to Justin Rabidoux who indicated it was acceptable. Any other instances of a storm line running close to a building are in areas where the line will remain private. 8. Tress should not be planted within easements for storm drains proposed to be taken over by the City. The plans will be adjusted at the Final Plan submittal to ensure no trees are planted within stormwater easements for storm lines. 9. The Vermont Stormwater Management Manual (VSMM) indicates that a 12’ wide maintenance access should be provided in order to facilitate equipment access for maintenance of stormwater ponds (section 2.7.1.F). Most of the ponds already show walking paths in the vicinity of the ponds. For the final plan submittal we will clarify and show a minimum of a 12’ wide stabilized surface for maintenance access. The visible gravel surface will remain 5’ wide, but the gravel subbase will be expanded to 12 feet, with a layer of topsoil and a grassed surface. A detail will be provided. 10. Stormwater Management “C” shows outlet structure near forebay berm. The riser should be located so that short‐circuiting between inflow points and the riser does not occur. Section 2.7.1.D of the VSMM recommends maintaining a long flow path through the system. Additionally, it is not recommend to place the Emergency Spill way over the outlet pipe, as depicted on the Sheet C‐9. We agree that the location of the outlet structure for Pond C is shown too close to the southerly forebay of the pond. This pond will have forebays on both ends, so the outlet structure will be relocated to the middle of the permanent pool to minimize short‐circuiting in either direction. 11. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure. The applicant is amenable to such a condition.

CUMMINGS—1811 SPEAR STREET & 25 HARBOR RIDGE ROAD PRELIMINARY & FINAL PLAT APPLICATION #SD-17-06 FINDINGS OF FACT AND DECISION Preliminary & final plat application #SD-17-06 of Donald R. Cummings for a planned unit development consisting of two (2) lots, each developed with a single family dwelling. The project consists of: 1) subdividing the 1.16 acre parcel into two (2) parcels of 0.6 acres (lot #1) and 0.56 acres (lot #2), and 2) relocating the zoning district boundary between the R-1 and R-2 Zoning Districts in conjunction with the planned unit development, 1811 Spear Street & 25 Harbor Ridge Road. The Development Review Board held a public hearing on April 18, 2017. The applicant was represented by Donald Cummings and David Marshall. Based on the plans and materials contained in the document file for this application, the Development Review Board finds, concludes, and decides the following: FINDINGS OF FACT 1. The applicant, Donald R. Cummings, seeks preliminary and final plat approval for a planned unit development consisting of two (2) lots, each developed with a single family dwelling. The project consists of: 1) subdividing the 1.16 acre parcel into two (2) parcels of 0.6 acres (lot #1) and 0.56 acres (lot #2), and 2) relocating the zoning district boundary between the R-1 and R-2 Zoning Districts in conjunction with the planned unit development, 1811 Spear Street & 25 Harbor Ridge Road. 2. The owner of record of the subject properties is Donald R. Cummings. 3. The subject properties are located in the Residential 1 and Residential 2 Zoning Districts. 4. The application was received on February 24, 2017. 5. The plans submitted consists of six (6) pages with the first page titled “Plat of Survey Donald Cummings,” prepared by Civil Engineering Associates, Inc., and dated 12/5/2016. A) Density The zoning district boundary between R1 and R2 cuts through the existing Harbor Ridge Road parcel. By adjusting the boundary line as proposed (i.e. in a westerly direction on Lot 1 and an easterly direction on Lot 2) the existing house on Harbor Ridge Road and the existing house on Spear Street will both be in the R1 Zoning District. The total R1 Zoning District area within the PUD and within which the existing houses will be located is proposed to be 2.05 acres, which is sufficient to accommodate the proposed density of two (2) housing units in that zoning district (1 unit/acre). The total R2 Zoning District area within the PUD is proposed to be 0.73 acres, which is sufficient to accommodate one (1) housing unit in #SD-17-06 2 that district (2 units/acre). The Board finds that the zoning district boundary line adjustment is necessary to advance the project as a PUD and therefore the Board finds the adjustment acceptable. B) PLANNED UNIT DEVELOPMENT STANDARDS Pursuant to Section 15.18 of the South Burlington Land Development Regulations, PUDs shall comply with the following standards and conditions: (A)(1) Sufficient water supply and wastewater disposal capacity is available to meet the needs of the project. A condition of plat approval will be that the applicant receive any necessary permits related to water and wastewater supply from the appropriate permitting agencies. (A)(2) Sufficient grading and erosion controls will be utilized during and after construction to prevent soil erosion and runoff from creating unhealthy or dangerous conditions on the subject property and adjacent properties. This is criterion is covered by the discussion below on stormwater. (A)(3) The project incorporates access, circulation, and traffic management strategies sufficient to prevent unreasonable congestion of adjacent roads. All two (2) proposed lots will be accessible from public roads. The existing two (2) houses already have driveways connecting them to either Spear Street (1811 Spear St.) or Harbor Ridge Road (25 Harbor Ridge Rd.) and when a house is developed on Lot 2 it will have access to Harbor Ridge Road via a shared driveway with 25 Harbor Ridge Road. The Board finds this criterion met. (A)(4) The project’s design respects and will provide suitable protection to wetlands, streams, wildlife habitat as identified in the Open Space Strategy, and any unique natural features on the site. The Board finds that none of the features listed in this criterion are present at the site. (A)(5) The project is designed to be visually compatible with the planned development patterns in the area, as specified in the Comprehensive Plan and the purpose of the zoning district(s) in which it is located. The project is located in low density residential zoning districts with many single family houses. The proposed dwelling unit that could be accommodated on Lot 2 would also be single family. The Board finds this criterion met. (A)(6) Open space areas on the site have been located in such a way as to maximize opportunities for creating contiguous open spaces between adjoining parcels and/or stream buffer areas. The subdivision of the property and the proposed location of a future house would preserve the expanse of open space behind the existing house at 1811 Spear Street. That backyard open space continues through #SD-17-06 3 the yards of several other houses to the north to Westview Drive and to the south to Allen Road. The Board finds this criterion met. (A)(7) The layout of a subdivision or PUD has been reviewed by the Fire Chief or (designee) to ensure that adequate fire protection can be provided. The Fire Marshall received project plans and no comments were submitted. (A)(8) Roads, recreation paths, stormwater facilities, sidewalks, landscaping, utility lines and lighting have been designed in a manner that is compatible with the extension of such services and infrastructure to adjacent landowners. The Board finds this criterion met. (A)(9) Roads, utilities, sidewalks, recreation paths, and lighting are designed in a manner that is consistent with City utility and roadway plans and maintenance standards, absent a specific agreement with the applicant related to maintenance that has been approved by the City Council. For Transect Zone subdivisions, this standard shall only apply to the location and type of roads, recreation paths, and sidewalks. The Board received the following comment from the Public Works Department in an email dated March 27, 2017: My only comment is to have the applicant pave the bottom portion of their driveway that is within the road ROW. Gravel always gets deposited in our road from this property, I’d like to clean it up as much as possible. The Board finds that this decision will contain a condition requiring the paving of the bottom portion of the driveway within the City right-of-way. (A)(10) The project is consistent with the goals and objectives of the Comprehensive Plan for the affected district(s). The project is located in the Southwest Quadrant where the Comprehensive Plan states future land use should remain principally residential and care should be taken to maintain and improve stormwater runoff. The project is residential and stormwater is discussed below. The Board finds the proposed project meets this criterion. C) SITE PLAN REVIEW STANDARDS Pursuant to Section 14.03(A)(6) of the South Burlington Land Development Regulations, any PUD shall require site plan approval. Section 14.06 of the South Burlington Land Development Regulations establishes the following general review standards for all site plan applications: A) Relationship of Proposed Development to the City of South Burlington Comprehensive Plan. Due attention by the applicant should be given to the goals and objectives and the stated land use policies for the City of South Burlington as set forth in the Comprehensive Plan. #SD-17-06 4 The Board finds that this criterion is being met as discussed above. B) Relationship of Proposed Structures to the Site. (1) The site shall be planned to accomplish a desirable transition from structure to site, from structure to structure, and to provide for adequate planting, safe pedestrian movement, and adequate parking areas. (2) Parking (3) Without restricting the permissible limits of the applicable zoning district, the height and scale of each building shall be compatible with its site and existing or anticipated adjoining buildings. (4) Newly installed utility services and service modifications necessitated by exterior alterations or building expansion shall, to the extent feasible, be underground. D) Relationship of Structures and Site to Adjoining Area. (1) The Development Review Board shall encourage the use of a combination of common materials and architectural characteristics (e.g., rhythm, color, texture, form or detailing), landscaping, buffers, screens and visual interruptions to create attractive transitions between buildings of different architectural styles. (2) Proposed structures shall be related harmoniously to themselves, the terrain and to existing buildings and roads in the vicinity that have a visual relationship to the proposed structures. At present no building is being proposed, the plans only show where a single family dwelling could possibly be located on Lot 2. The Board finds the existing mature trees will help create desirable transitions when a building is constructed on the site. The Board finds that the height and scale of the future single family dwelling should be compatible with the site and the neighboring houses, the utilities should be underground to the extent feasible, and the structures within the PUD should relate harmoniously to themselves and the terrain. In addition to the above general review standards, site plan applications shall meet the following specific standards as set forth in Section 14.07 of the Land Development Regulations: 1. Access to Abutting Properties. The reservation of land may be required on any lot for provision of access to abutting properties whenever such access is deemed necessary to reduce curb cuts onto an arterial or collector street, to provide additional access for emergency or other purposes, or to improve general access and circulation in the area. The Board does not consider the reservation of land to be necessary. 2. Utility Services. Electric, telephone and other wire-served utility lines and service connections shall be underground. Any utility installations remaining above ground shall be located so as to have a harmonious relation to neighboring properties and to the site. Pursuant to Section 15.13(E) of the Land Development Regulations, any new utility lines, services, and service modifications must be underground. #SD-17-06 5 3. Disposal of Wastes. All dumpsters and other facilities to handle solid waste, including compliance with any recycling or other requirements, shall be accessible, secure and properly screened with opaque fencing to ensure that trash and debris do not escape the enclosure(s). The applicant is not proposing any new dumpsters or other facilities at this time. 4. Landscaping and Screening Requirements. (See Article 13, Section 13.06) No construction is proposed as part of this application. The Board finds this criterion inapplicable. D) SUBDIVISION STANDARDS 15.10 Lot Layout A. Lots shall be laid out in such a way that they can be developed in full compliance with these land development regulations, and giving consideration to topography, soils, and drainage conditions. B. Except within the City Center FBC District, the following standards shall apply: Corner lots shall have extra width to conform to setbacks on each street. No subdivision showing any reserved strips shall be approved. A width to length ratio of one to five (1:5) shall be used as a guideline by the Development Review Board in evaluating lot proportions. Developments consisting predominantly of square or roughly square lots or lot with an excessive length to width ratio (i.e. spaghetti lots) shall not be approved. Existing Lot 3 will have a ratio of approximately 1:3 and Lots 2 and 3 a ratio of approximately 1:2.5. The existing lot on Harbor Ridge Road currently has a ratio of close to 1:1, therefore the subdivision will create two (2) lots with ratios closer to the recommended 1:5. The existing lot on Spear Street will maintain the same ratio. In combination with the applicant’s request to change the location of the zoning district boundary lines, the proposed lots can be developed in compliance with the land development regulations. The Board finds these criteria to be met. E) WAIVERS The applicant is requesting that the side setback on the north side of Lot 1 be reduced from the required 25 feet to 15 feet to allow for a future possible expansion to the existing house on Lot 1. The side setback along the north side of Lot 1 abuts Lot 2, which is mostly in the R2 Zoning District where only a 10 foot side setback is required. The Board finds the requested 15 foot side setback to be compatible with development patterns of the neighborhood. F) STORMWATER The Board received the following comments from the Stormwater Section in an email dated 4/14/2017: 1. This project is located in the Bartlett Brook watershed. This watershed is listed as stormwater impaired by the State of Vermont Department of Environmental Conservation (DEC). 2. It is understood that the applicant has proposed to install a bioswale to treat stromwater runoff from the proposed development. 3. While not a requirement, the applicant could consider installing a gutter along the back roof of the proposed house in order to direct additional runoff toward the bioswale. #SD-17-06 6 Thank you for the opportunity to comment. The Board encourages, but does not require, the applicant to consider the advice of the Stormwater Section regarding the installation of a gutter if a new dwelling unit is ever built. DECISION Motion by __________, seconded by ___________, to approve preliminary & final plat application #SD- 17-06 of Donald R. Cummings subject to the following conditions: 1. All previous approvals and stipulations will remain in full effect except as amended herein. 2. This project must be completed as shown on the plat submitted by the applicant and on file in the South Burlington Department of Planning and Zoning. 3.

We are requesting that the setback line on the north side of Lot 1 be reduced from 25’feet to 15’. This value is still less than the 10’value associated with the R2 district and what is being use on the undeveloped proposed Lot 2 parcel immediately to the north. The proposed relief from the 25’standard will enable the potential expansion of the existing building footprint in an orderly manner which reflects the current interior layout of the house. The conceptual footprint additions are shown on Sheet C1.1and reflect previous planning efforts with a local architect on how best to enable the existing home to be retained and expanded. 2.Water Service Revision –In working with Mr.John Tymecjki from the Water Department,the proposed water service for the new Lot 2 has been revised to benefit from the higher pressure available from the water main on the west side of Harbor Ridge Road. 3.Stormwater –In speaking with Mr. Dave Wheeler from Stormwater Services,he asked that the proposed use of the bioretention area be supported with a basis of design. This has been completed (see attached letter to Dave Wheeler) and the Ms. Lindsey Britt Page 2 of 2 April 7, 2017 plans have been updated to reflect the level of detail described in the supporting letter. The proposed bioretention system has bene relocated to the east so as to enable the retention of the existing trees located along the west property line. 4.Subdivision Plat –The plat has bene revised to reflect: a.the Lot 1 setback waiver request,, b.the retention of an electrical easement across lot (favoring Lot 1) 5.Sheet C1.0 –Proposed Site Plan –Has been revised to show the proper orientation of the proposed regulation extensions and lot numbers consistent with that originally submitted plat plan. 6.Sheet C1.1 –Proposed Site Plan –Has been revised to show: a.the proper location of the existing sewer service, b.the preferred location for the new water service for Lot 2, c.additional callouts for the abandonment of the portions of the existing sewer service line to be taken out of service, d.orientation of the proposed regulation extensions and lot numbers consistent with that originally submitted plat plan. e.depiction of the existing electrical service. 7.Sheet C2.0 –Details –modifications of the bioretention detail and the inclusion of a yard drain detail. This completes our summary of the recent revisions to the application components.If you should have any questions, please feel free to contact me at 864-2323 x310. Respectfully, David S.

MEMBERS PRESENT: B. Miller, Acting Chair; J. Smith, D. Parsons, J. Wilking, F. Kochman, ALSO PRESENT: R. Belair, Administrative Officer; L. Britt, Development Review Planner; M. Sperry, P. Judge, E. Barfed, S. Livofson, A. Rowe, T. McKenzie, K. Braverman, C. Snyder, B. Williams, G. Maille, J. Leinwohl, K. Sturtevant, J. Duncan, J. Pidgeon, A. Gill, M. Waite, S. Rendall, M. Janswold, R. Rushford, J. Desautels, A. Clayton, J. Duncan Mr. Miller provided emergency exit information. 1. Additions, deletions, or changes in order of agenda items: No changes were made to the Agenda. 2. Comments & Questions from the public not related to the Agenda: No issues were raised. 3. Announcements: No announcements were made. 4. Continued Preliminary and Final Plat Application #SD-1703 of Snyder-Braverman Development Company, LLC, to subdivide a 5.15 acre parcel into three lots ranging in size from 12,589 sq. ft. to 183,150 sq. ft., 6 Market Street: Mr. Snyder advised that the right-of-way has been shifted entirely onto the South Burlington City Center parcel. Mr. Parsons said this is what the Board discussed 2 weeks ago. Mr. Sperry, representing the adjacent property owner, requested bonding or other security. He noted that Century Partners gets a lot of cut-through traffic. He hoped the city would extend Market Street to eliminate that. Mr. Judge said it is a safety concern. Mr. Belair said a bond is not required at this level; this is just the creation of 3 lots with no development involved. DEVELOPMENT REVIEW BOARD 21 MARCH 2017 PAGE 2 Mr. Kochman added that unless a zoning permit is required, a bond is not required. Mr. Sperry said if the Board says nothing, the applicant can say they weren’t told a bond would later be required. Mr. Belair responded that a bond is always required before a street can be constructed. Mr. Snyder read from the regulation 8.04(A) (2) regarding bonding requirements. Mr. Sperry said he would feel better if something got said about it. Mr. Belair said the city’s attorney says that if something is in the regulations, it does not have to be put in the decision. Mr. Wilking then moved to close #SD-17-03. Ms. Smith seconded. Motion passed 5-0. 5. Appeal #AO-1701-01 of Burlington International Airport (BIA)/City of Burlington (COB) appealing the issuance of Zoning Violation #NV-17-01 by the Administrative Officer alleging a zoning violation at 3060 Williston Road: Ms. Sturtevant, representing the City of Burlington, asked for a continuance to a future meeting. She noted this property has tenants, and the Airport is working with the tenants to resolve the issues, so there may not be a need for a hearing. Mr. Belair noted the site plan had been changed without approval. Violations include the placing of 2 dumpsters, a large storage container and outside storage on the property without approval. Ms. Sturtevant said these items have now been removed. Ms. Clayton added that the tenants were given two options: get site plan approval or remove the items. They removed the items. Mr. Belair noted there may also be some tenants in the building who were not approved as required. Mr. Wilking moved to continue Appeal #AO-17-01 to 2 May 2017. Mr. Parsons seconded. Motion passed 5-0. 6. Appeal #AO-17-02 of Burlington International Airport (BIA)/City of Burlington (COB) appealing the issuance of Notice of Violation #NV-17-02 by the Administrative Officer alleging a zoning violation at Valley Road (quarry north of 3060 & 3064 Williston Road): DEVELOPMENT REVIEW BOARD 21 MARCH 2017 PAGE 3 Ms. Sturtevant asked for a continuance. Mr. Belair explained that there is a provision that requires approval for placing of fill. The placement in this case was more than the allowable 20 cubic yards. That placement has now stopped. Ms. Sturtevant said the fill was placed by the Air Guard without notice to the Airport. The Airport had gone through sketch review to place the fill in the quarry. The placement happened in between. Ms. Sturtevant said they are ready with preliminary and final plat and asked for scheduling as early as possible. Mr. Wilking moved to continue Appeal #AO-17-02 to 2 May 2017. Ms. Smith seconded. Motion passed 5-0. 7. Re-opened site plan review application #SP-16-82 of City of Burlington, Burlington International Airport to amend a previously approved plan for an airport complex. The amendment consists of: 1) relocation of taxiway “G,” 2) new aircraft holding bay, 3) relocation of taxiway “A,” 4) reconstruction of taxiways “M” & “H,” and 5) stormwater improvements, 1200 Airport Drive: Mr. Leinwohl said they have a mitigation plan to address the issues raised by the City. He showed a photo and diagram of the holding area and noted that when a plane is parked there awaiting take-off, there is a jet blast that blows snow onto Airport Parkway. The plan to address this is to build an earth berm, 10 feet high. It would be vegetated with landscaping to improve the public side. This would address the issue at one of the holding bays. The other bay abuts property owned by the City of South Burlington, and the Airport would need an agreement with the City of South Burlington to extend the berm. Mr. Leinwohl showed the boundary of the 35 mph velocity. He noted that the wind in the area dissipates at 15 mph for every 40 feet. Mr. Belair said staff would like to know where the velocity drops to zero. He suggested continuing the hearing to that information can be provided. Mr. Leinwohl said they did that research. The velocity is reduced to zero by the time you reach Airport Parkway. He added that the wind would have to be blowing east to west to impact that, which is very unusual. DEVELOPMENT REVIEW BOARD 21 MARCH 2017 PAGE 4 Mr. Wilking noted the berm is very long and asked about truck trips for the building of the berm. Mr. Leinwohl said they haven’t gotten that specific yet. Mr. Wilking said the neighborhood has had a lot of impact from the Airport, and this work could add to traffic, etc. He wanted to know the specifics. Mr. Leinwohl said they can use a lot of material from the construction work to construct the berm, which would reduce trucking. Mr. Wilking asked about the possibility of a blast wall for the entire area. Mr. Leinwohl said that would not be as aesthetically pleasing. Mr. Wilking asked if it could address noise issues. Mr. Leinwohl said it is not a noise controller as it is a different kind of wall. Mr. Kochman questioned the impact on the South Burlington property if the berm is extended or even just from the blast across it. Mr. Wilking said that Cty property is a big gully with not much use. Ms. Clayton said the Airport would love to put a blast wall there, but could do it only if the gully were to be filled in. Regarding traffic during the construction, Mr. Leinwohl showed a plan indicating the project area. He showed the route that trucks would take with material taken out and removed to the quarry. He estimated 5500 truck trips going out in 2017 and 6400 ion 2018. This would average out to 3 trips in and out (round trips) per hour, depending on what phase of building is going on. He showed a graph of estimated truck traffic due to phasing. Regarding materials coming in (stone, pipe, etc.), there are 2 likely routes, depending on which contractor is used (the project has not yet been bid). Traffic would come from either the east or west on Williston Road. Mr. Leinwohl estimated 5 trips per hour through the Williston Road intersection. Mr. Wilking said he would want assurance that the trucks stay on Williston Road and do not go through the neighborhood. Mr. Leinwohl said that will be part of the bidding package. Mr. Kochman asked about night construction. Mr. Leinwohl said there will be night work for one part where the taxiway meets the runway. Ms. Clayton said that will take place between midnight and 5 a.m., when there are no flights. DEVELOPMENT REVIEW BOARD 21 MARCH 2017 PAGE 5 Mr. Wilking asked how noise from trucks backing up near homes can be mitigated. Ms. Clayton said they can have a turn-around instead of having trucks backing up. Mr. Leinwohl said this can be done in “vulnerable locations.” Mr. Belair said that can be a condition. Mr. Wilking said it should be anywhere the noise can travel. Mr. Leinwohl said he wasn’t sure that was feasible from the contractor’s point of view. They have to have back-up indicators, but they can talk about how to minimize that. Mr. Wilking stressed that 2-1/2 months of backing up truck noise is not acceptable. Mr. Leinwohl said they will do whatever they can. Mr. Belair noted one issue with the proposed berm. Part of it would be on an adjacent property owned by the City of Burlington, which would have to apply to have the berm on that property. It would have to be a separate application. Ms. Sturtevant cited the need to move forward. She said they can have a revised site plan and a separate site plan for the adjacent property. Ms. Britt said the City does not want to leave anything unsettled. Mr. Belair said he can’t craft conditions until he has specifics. Ms. Clayton said the original hearing was 17 January, and this is a “real heartbreaker” for the Airport, especially regarding their ability to apply for grants. She asked if Phase 1 can be approved separately. Mr. Wilking noted that the problems created were not addressed by the Airport at the time of the hearing. Mr. Belair suggested excluding the holding bay area from the plan and having the DRB approve the rest. Ms. Clayton said that would allow them to proceed in a timely manner. They will need permits in hand by 1 May. DRB members were OK with removing the holding bays from the application. Mr. Belair said there is no decision written, but it can be created and e-mailed to members and try to expedite the process to less than 2 weeks. Mr. Maille, a resident of the area, stressed that blast walls would not provide noise mitigation. DEVELOPMENT REVIEW BOARD 21 MARCH 2017 PAGE 6 He also noted that the Chamberlin Neighborhood Airport Planning Committee (CNAPC) had identified a bike path on Airport Parkway. He wasn’t sure of the time frame for this, but the concern is that without a berm, there could be a hazard to pedestrians and bikers when that path is created. A full berm across the area would be needed to mitigate the problem. He suggested the possibility of BTV buying the South Burlington land and filling in the gully to make it conducive to building a blast wall. Regarding noise and traffic, Mr. Maille said that during the 2010 project, the noise was “maddening.” It was hard to sleep between 1 and 5 a.m. He also cited the difficulty of getting out of his street today and suggested that it would help to have a traffic light there, even a temporary light during the construction. No other issues were raised. Mr. Wilking moved to close #SP-16-82 with the condition of removing the holding bays and berm from the application. Mr. Parsons seconded. Motion passed 5-0. 8. Conditional Use Application #CU-17-02 of Champlain Water District for approval to allow an accessory structure (water storage tank) to exceed the height of the principal structure by 32 feet, 403 Queen City Park Road; and 9. Site Plan Review Application #SP-17-12 of Champlain Water District to amend a previously approved plan for a municipal water treatment plant. The amendment consists of: 1) constructing a below grade concrete wet well expansion with a pump room and a pipe gallery, 2) constructing a 1.0 million gallon precast concrete filtered water storage tank, and 3) site modifications, 403 Queen City Park Road: Mr. Duncan explained that CWD is making improvements to the plant. Since they can’t take equipment out of service to make the improvements, they are putting in a duplicate system. He noted that 2 floors of the building are below grade, and only one above grade. One other structure will be visible from the road. Mr. Duncan indicated a parking area and fire access road. The road will be shifted to the east side to accommodate the wet well. Parking will be relocated along the east side. Mr. Duncan showed the location of the new tank and new wet well on an overhead photo and indicated where the road will come. DEVELOPMENT REVIEW BOARD 21 MARCH 2017 PAGE 7 Mr. Parsons asked about getting the road aligned with Pine Street. Mr. Duncan said that would require the relocation of 2 poles (Green Mountain Power). He added that the present alignment is more conducive to truck deliveries. Mr. Kochman asked if there are rules for “dog legs.” Mr. Belair said only for streets. He added that Public Works is OK with this alignment. Mr. Duncan noted that the new road will not be for daily use; it will be gated. Mr. Kochman said he doesn’t have a practical problem with it; his problem is with the rules. Ms. Britt said Mr. Conner had no issues with it, and he oversees the writing of the rules. Ms. Lindsey noted that staff did not see a need for conditional use approval and they view this as multiple structures in a complex. This eliminates the need for a height waiver. Mr. Duncan said they will submit a withdrawal of the Conditional Use Application. Mr. Parsons asked about landscaping. Mr. Duncan indicated new plantings. He noted that some scrub brush will be removed and there will be trimming on the other side and under GMP lines. They will screen the dumpsters. No other issues were raised.

The amendment consists of adding one single family dwelling to lot #3, 7 Chaplin Lane: Ms. Britt noted that previous stormwater issues have been resolved. Mr. Kochman noted the applicant is applying for a footprint lot. Ms. Desautels said they will sell with the ability to build a house. Mr. Kochman said he thought that was illegal and will vote against it. Ms. Desautels explained the need for a street sign and said they will get that done. She also noted the new unit will be required to have a sprinkler system. DEVELOPMENT REVIEW BOARD 21 MARCH 2017 PAGE 8 Ms. Bartlett, a neighbor to the north, asked about stormwater. Ms. Desautels indicated the location of a swale that picks up drainage. More detail has been added to the swale (it will be constructed in the spring when the ground thaws). New drainage will be directed to the pond. No other issues were raised. Mr. Wilking moved to close #SD-17-04. Mr. Parsons seconded. Motion passed 4-1 with Mr. Kochman opposing. 11.

Mr. Belair said he can provide a manual to address that when the applicant applies for a permit to build the house. An energy certificate will have to be recorded when the house is finished.
