The land in the area of the development is zoned Residential District (7). Planned Unit Development is a permitted use in this zoning district. Lot 1 of the Home Farm Development, to be known as Stonington Circle, includes 47 townhouse units on a 8.7 acre lot and Lot 2, to be known as Lancaster Place, includes 60 multi- family units on a 5.0 acre lot. Lot 3 is a 2.0 acre lot to remain open land There will also be approximately 2.7 acres dedicated to the City of South Burlington that will be improved to contain a paved road, curbs, bike path, drainage, water and sewer lines and street trees. The Home Farm Development has been designed to efficiently utilize the land, and is in general conformance with the following standards of Section 26.15 of the South Burlington Zoning Regulations. Al) The multi -families will be designed to have five one bedroom units and ten two bedroom units in each building, and the townhouses will be designed to have up to three bedroom units. The State of Vermont indicates the design water and sewer flow for a three bedroom unit is 450 gal/day/unit, 300 gpd for a two bedroom unit and 150 gpd for a one bedroom unit.. Connection to municipal sewer and water saving devices allow the design flow to be reduced 20% to 360 gal/day/unit, 240 gpd, and 120 gpd respectively. Measurement of actual flows for three bedroom units indicate water and sewage flows of approximately 230 gal/unit/day and approximately 150 gal/unit/day for the two bedroom units. There are a total of 47 townhouse units, 40 two bedroom units, and 20 one bedroom units. The design flow for these units would be no more than 32,493 gallons per day. The sewer flow will likely average 18,750 to 20,000 gallons per day at full buildout. Krebs and Lansing Consulting Engineers met with the South Burlington City Engineer to discuss the capacity of the City sewage collection system. It was our understanding that the City has adequate capacity to treat the daily sewage flow but, there was concern that the sewage collection lines in the vicinity of Kennedy Drive and Hinesburg Drive might be close to capacity. Krebs and Lansing and Heindel and Noyes installed equipment to continuously monitor the sewer line flow at the intersection of Hinesburg Road and Kennedy Drive for a period of eight days. We made the following observations, and have submitted them to the City Engineer, Bill Szymanski, for his review. Page 1 of 7 Narrative O'Brien Home Farm Development 1. The sewer pipe crossing Kennedy Drive has a 10" diameter, City records indicate an 8" diameter pipe. 2. The pipe flow rates range from approximately 9 gpm at night to 500 to 600 gpm flow rates during peak flow times. 3. The maximum flow rate recorded was 900 gpm (likely from simultaneous pump station discharges from adjacent developments). 4. Approximately 90% of the time the pipe carries less than 20% of its capacity and the pipe is carrying approximately 50% of its capacity during peak flow times. Based on a 16 hour day, the average flow from the O'Brien Home Farm Development is projected to be 21 gallons per minute. Using a peaking factor of 5, the peak flow rate is projected to be 105 gpm. Based on our continuous flow observations of the sewer collection pipe crossing Kennedy Drive, we estimate the pipe could flow at least 1200 gal/minute. The existing peak flows measure 500 to 600 gpm. Given this information, we feel the sewage flow from the O'Brien Home Farm Development will not have undue adverse affects on the South Burlington sewage collection infrastructure. (See results of continuous monitoring included as Attachment 1.) A2) The area of the O'Brien Home Farm Development is not located in a flood plain. A3) A stormwater runoff analysis was performed on the proposed development of the O'Brien Home Farm. The site was analyzed from Kimball Avenue on the north, Old Farm Road to the east, Hinesburg Road to the south and the condominium developments to the north. The site was analyzed utilizing the SCS TR55 stormwater model and Haestad Methods Pond Pack version 7 software for the 24 hour, 25 year pre development and post development conditions. The site was analyzed as 5 sub watersheds. With the use of stormwater treatment and detention structures, the following results were obtained for the 24 hour, 25 year storm event. Watershed Pre -Development Peak Runoff (cfs) 1 0.5 2 2.4 3 4.4 4 1.5 5 5.8 Total Pre -Development Runoff 14.6 cfs Post Development Peak Runoff (cfs) 0.5 2.4 3.5 0.6 1.6 8.6 cfs Total Post - Development Runoff Detention basins have been designed utilizing the current Vermont Best Management Practices for Treatment of Stormwater Runoff. The basins will collect and hold the first inch of runoff for 24 hours. The basins will have provisions for them to remain wet, utilizing sumps for polishing of stormwater. Page 2 of 7 Narrative O'Brien Home Farm Development The development has been designed to provide treatment of stormwater runoff from much of the roads and parking via sheet flow over vegetated terrain and grass lined swale. The downslope portions of the site will be banked by vegetated buffers and the 50 foot wide wetland buffers will not be disturbed. In addition, a significant portion of the parking in both Stonington Circle and Lancaster Place will be in covered garages, lessening the potential for pollution causing contaminants. The construction plans for the project include temporary erosion control measures such as stone check dams, rip rap outlets, hay bale and silt fence barriers, stabilized construction entrance, re-establishing vegetation in disturbed areas as soon as possible, avoidance of wetlands and wetland buffers and ongoing inspection and maintenance of erosion control measures. Temporary sedimentation basins have been designed to prevent sediment laden runoff from leaving the site during construction.(See Attachment 2 stormwater analysis and plans.) A4) The Applicant believes the proposed development of the O'Brien Home Farm has been designed in conformance with all local and State regulations. B) The O'Brien Home Farm Development will require water for domestic use and fire flows. Based on a 16 hour delivery day, the average day demand for 47 townhouses and 60 multi -family units is estimated to be 35f gallons per minute. Using a peaking factor of 5, the peak flow rate is estimated to be 175± gpm. A desirable fire flow is estimated to be 1500 to 2000 gpm. We have completed a water distribution model for the development and submitted a Construction Permit for Public Community Water Systems with the State of Vermont Agency of Natural Resources Water Supply Division. (See Attachment 3 water system analysis). The results of our model indicate a fire flow of at least 1500 gpm can be maintained throughout the project. C) The proposed development of the O'Brien Home Farm has been designed to control and direct stormwater runoff into detention basins that will treat and release the runoff at rates equal to or lower than pre -development stormwater runoff levels. The development will preserve all of the wetlands and their buffers shown on the site plan, and will provide a vegetated buffer strip on the down slope sides. Temporary erosion control measures will be established and maintained during construction. These measures include stone check dams in all swales, silt fence installation downslope of construction activities, rip rap pads at storm pipe inlets and outlets, and temporary sedimentation ponds. Permanent erosion control measures include establishing permanent vegetation, paving roads and parking lots, rip rap dispersal pads, and maintaining stormwater collection and treatment facilities. Page 3 of 7 Narrative O'Brien Home Farm Development D) See Attachment 4, traffic report prepared by Roger Dickinson, P.E., Lamoureux & Dickinson Consulting Engineers. E) A letter from the South Burlington School District was previously submitted with the Preliminary Subdivision Plat Review. F) The Applicant feels the proposed development of the proposed O'Brien Home Farm Development will not cause an unreasonable burden on the City of South Burlington to provide municipal or governmental services and facilities. The site is located close to the core of the City in an area designated for high density development. The circulation roads serving the townhouse and multi -family units have been proposed as private roads minimizing municipal road maintenance on the site. The road to be dedicated to the City will be constructed to City standards, every effort will be made to minimize future maintenance costs to the City associated with this segment of road. The buildings and site will be designed to conform with fire codes. The water system will provide adequate hydrants and the circulation road within the development will provide adequate circulation for emergency vehicles. The Applicant believes the project has been designed to restrict the risk of fighting fires or performing emergency rescue to acceptable levels. The site is located in close proximity to the core of the City in areas already patrolled by the South Burlington Police Department. Roads and road intersections will be designed in conformance with State and local regulations. The use of bus services to commute from the site is feasible and will contribute to less congestion. The design of bikeways and pedestrian connections will help to promote safe pedestrian circulation. The compact nature of the development will make routine police patrols quicker and easier. G) A design goal of the O'Brien Home Farm Development has been to avoid important natural resources. Before any design work proceeded, the site was evaluated for wetlands, rare and endangered species, wildlife habitats and special features. See letter from Errol Briggs, Biologist (Attachment 6). The results of the evaluation indicated wetlands, and a small intermittent stream associated with a wetland, were important features. The design study employed was to identify a 50 foot wide buffer around the wetlands and stream and to leave the features and their buffers undisturbed (see site plans). H) See narrative regarding site aesthetics prepared by T.J. Boyle & Associates, Landscape Architect (Attachment 7). The Applicants have employed the University of Vermont Archaeology Consulting program to perform Phase 1 and Phase 2 Archaeological Assessments of the site. These assessments determined an archaeologically sensitive area near the Lancaster Lane portion of the project, as shown on the plans. The design of Lancaster Lane and the Page 4 of 7 Narrative O'Brien Home Farm Development multi -family units avoids the archaeologically sensitive area. No subsurface disturbance is proposed nor is it allowed in this area without prior written approval from the Department of Historical Preservation. I) See narrative regarding open space and conformance with City Recreation Plan prepared by T.J. Boyle & Associates, Landscape Architect (Attachment 7). J) The O'Brien Home Farm Development will provide local streets, Magalloway Street, Hillsborough Drive, and Eldredge Street with a bike path, street trees, curbs and infrastructure constructed to South Burlington road standards connecting Hinesburg Road and Kennedy Drive. The street is partially located in a corridor identified by the City as a future street. The Applicant is working in conjunction with the City of South Burlington and the State of Vermont's engineering consultant, McFarland Johnson, to design a safe and efficient entrance to Kennedy Drive from the development. Magalloway Street is proposed as an intersection with Hayes Avenue to the south and will serve an important function to connect the pedestrian circulation between the existing developments on the south and east sides of Kennedy and Hinesburg Drives. K) The proposed streets loop through land owned by the Applicants. Should there be consideration of future development by adjoining property owners or the City of South Burlington, provisions have been made to accommodate water services and stormwater services and a road profile not exceeding 10% can be provided. The Town Plan identifies a local street link from Hinesburg Road to Old Farm Road as desirable. The proposed Magalloway Street and Hillsborough Drive can accommodate that extension. As indicated in the Findings of Fact for the Preliminary Plat application, the City Engineer has reviewed the plan. L) Compliance with the South Burlington Comprehensive Plan The Applicants feel the proposed development of the O'Brien Home Farm is in conformance with the following sections of the South Burlington Comprehensive Plan: Chapter III Comprehensive Plan Goals The proposed development will advance the goals of the open space preservation, protection of wetlands, provide public landscaping, and provide outdoor recreational facilities. The proposed development is located in an area which has been zoned for high density residential use. The proposed development will be in an area already being used for compact urban development. The layout of the proposed development allows for compact urban densities while providing open space to protect adjacent wetlands and wetland buffers as well as provide land for public recreational use. The multi -family units and the townhouse units will provide quality housing which will be more efficient and use less land than single family housing. The proposed development will be located on or in close proximity to an existing Chittenden County Page 5 of 7 Narrative O'Brien Home Farm Development Transportation Agency bus route which will encourage the use of cost effective, environmentally sound transportation to commute the work, shop or recreational activities. The proposed development will serve to extend a local street, a bikeway and water & sewer infrastructure into an area designated by the comprehensive plan as desirable for compact urban residential development. The development will also provide public recreational spaces, landscaping, protect open space, and is in general conformance with the zoning and subdivision regulations of the City of South Burlington. Chapter IV Population The proposed development of the O'Brien Home Farm would result in the addition of 107 living units. From start to finish, the estimated time to complete the project would be 2.5 to 3.5 years. The estimated occupancy per unit is 2.3 persons. On a three year buildout, this would result in a 82 person increase in the population per year. This would represent slightly less than a .6% yearly growth in the South Burlington population. The comprehensive plan's stated objective is to limit population growth to 1.5% per year to promote a vital and healthy community. Chapter V Land Use The proposed development of the O'Brien Home Farm is in an area shown on Map 6 of the future land use plan to be high density residential use. The proposed development utilizes an average density of seven units per acre and is consistent with the plan's future land use pattern generally consisting of a higher density, compact urban core. Chapter VI HousinE See Attachment Chapter IX Natural Resources Areas of wetlands have been identified on the O'Brien Home Farm. The wetlands and their buffers were identified before any design of the O'Brien Home Farm commenced. The proposed development avoids the wetlands and their buffers. This design study is consistent with the comprehensive statement that ... special care needs to be taken so that the remaining wetlands are carefully protected.... The proposed development of the O'Brien Home Farm will include stormwater detention and treatment basins to treat stormwater using best management practices recommended by the State of Vermont before discharging stormwater into the watershed. In addition, vegetative buffers will be maintained along the downslope side of the development, and temporary and permanent erosion control measures will be employed during construction of the development. Page 6 of 7 Narrative O'Brien Home Farm Development Chapter X Recreation The proposed development of the O'Brien Home Farm will provide a public bikeway from Kennedy Drive to Hinesburg Road and access easements to the open land. These facilities are consistent with the comprehensive plan's goal... to provide for varied recreational needs and interests of its citizens by providing areas and_ facilities for passive recreation, active sports, cultural and educational programs... Chapter XI Path System tem The proposed development of the O'Brien Home Farm will provide a pedestrianibicycle trail connecting Kennedy Drive to Hinesburg Road along the corridor defined on Map 2 of the comprehensive plan. Chapter XII Transportation The proposed development of the O'Brien Home Farm is adjacent to an existing Chittenden County Transportation Authority bus route. The close proximity of the development to the City core will encourage residents of the development to use the bus to commute to work, shopping and recreation. The proposed development of the O'Brien Home Farm will include a bicycle/pedestrian corridor from Kennedy Drive to Hinesburg Road, helping to enhance a more pedestrian friendly environment for residents of the Home Farm and surrounding developments. The proposed development of the O'Brien Home Farm proposes the construction of local roads.. These roads will be designed for low speed use. The proposed road has been designed to allow a connection to Old Farm Road as shown by Map 3 of the South Burlington comprehensive plan. Chapter XVI Ene= Conservation The units proposed for the O'Brien Home Farm will be designed and constructed utilizing guidelines and recommendations from Energy Rated Homes of Vermont. The compact nature of the proposed development compared to a single family house development will create significant energy savings by lowering the surface are of roofs and walls exposed to the cold by approximately 50%. There are additional energy savings in less maintenance of lawns, driveways, and area lighting because the Home Farm Development will occupy approximately 14 acres of land. A single family development with the same number of units would occupy 25 to 50 acres of land. The close proximity of the Home Farm Development to the City core should result in savings of energy costs for gasoline. Residents will be able to use the bus, bike and walk to work, school, shopping and recreation.

Box 64709 Burlington, Vermont 05406-4709 February 9, 2001 Mr. Michael Burke Krebs and Lansing Consulting Engineers, Inc. 10 Main Street Colchester, VT 05446 • Consulting Hydrogeologists • Engineers • Environmental Scientists 802-658-0820 Fax 802-860-1014 Re: Sewer flow monitoring, Feb. 2 to 8, 2001; Corner of Rte. 116 and Kennedy Drive, So. Burlington Dear Mike: Enclosed please find the results of the sewer flow monitoring which Heindel and Noyes performed at your direction in a South Burlington municipal sewer pipe located at the intersection of Route 116 and Kennedy Drive. Method: We collected one week of detailed flow data using a pressure transducer which we placed on the floor of a ten -inch sewer pipe, at a location 2 feet north (downstream) from the manhole at this intersection. Instantaneous liquid levels were recorded by an automatic data -logger at ten-minute intervals between February 1, 11:30 AM, and February 8, 11:20 AM, 2001. Weather: Temperatures during the study week were generally below freezing. A total of 9.5 inches of snowfall was recorded at the Burlington Airport during this week. Because of the cold temperatures, it is unlikely that there was a significant amount of infiltration of surface water into this sewer pipe during the study week. Results: The pressure transducer data indicate that the sewer pipe was flowing well below its capacity during our one -week study. The hydrograph of liquid levels (see page 1 of the Attachment) shows that the liquid levels rarely exceeded 40% of the full diameter of the pipe. Only once during the week did the liquid level exceed half -full; this was on February 2, at 10:10 PM, when the level reached 58% of pipe -full condition. The data indicate that the sewer pipe was less than 36% full for 90% of the time. The average recorded liquid level during the study week was at 20% of pipe -full condition (see statistics at end of summary table in Attachment). Liquid Levels versus Flow Rates: We should point out that in a circular pipe that is not pressurized, such as this gravity sewer pipe, there is not a linear relationship between the liquid level in the pipe (height of water measured up from the bottom) to the flow rate of liquids in the pipe (measured in gallons per M. Burke re: Rte. 116 / Kennedy Dr. sewer pipe; February 9, 2001; Page 2 minute for example), due to the geometry of the pipe. For example, at 58% liquid level (the highest recorded in our study week), the pipe would be at 50% of its calculated flow capacity. At 36% liquid level (the 90th percentile of our recorded liquid levels), the pipe would be at 20% of its flow capacity. At the average liquid level of 20%, the pipe was at about 7% of its flow capacity. The theoretical maximum flow capacity would occur when the pipe is 97% full. Daily Fluctuations: During the week of monitoring, the sewer flows followed a regular pattern without significant variation. Flows were lowest during the early morning hours, and were highest during the daytime. Sewer flows rose and fell sharply, presumably due to the activation of pumping stations upstream. Estimations of actual flow rates: In our experience, it is not possible to mathematically convert the liquid level measurements to accurate flow rates (in gpm, or cfs). This is because "uniform flow" rarely occurs in storm sewers, sanitary sewers, and similar channels due to the effects of pump stations, sediment, solids, and rapidly changing slopes and pipe dimensions. Without uniform flow conditions, the mathematical equations that convert liquid levels to flow rates are not valid or accurate. The most accurate way to determine flow rates over a long period of time is to measure various individual flow rates (using a calibrated weir or some other measuring device) while simultaneously measuring the liquid levels, under several different flow conditions. Then, we could develop a "rating curve" that would mathematically characterize the flow rates over a range of different liquid levels. You indicated that this level of accuracy was not necessary for this particular project, and that the important information needed was relative to the percent of pipe -full capacity in this sewer pipe. Given those cautionary statements about the questionable accuracy of predicting flow rates from liquid levels in this circumstance, we have provided estimated flow rates for this study period, using two standard formulas for uniform flow in culverts and open channels. These calculations provide an estimated range of possible flow rates each time the liquid level is measured, based on the measured liquid level, the known slope and shape of the pipe or channel, and an estimated roughness coefficient. Uniform flow theory assumes that the velocity of flow can be determined, based on the balance between gravity and resistive forces (friction). For a uniform flow to occur, the slope, shape, and depth of the flow must be constant along the length of the channel. Since these conditions do not exist in the sewer pipe that we monitored, these flow calculations must be viewed as estimates only. See the calculation brief at the end of the Attachment, and the calculation results and parameters on the 23-page summary table. Using two different calculation methods —the inlet -controlled culvert formula, and the Manning formula for uniform flow — we have estimated the range of likely flow rates under ideal uniform flow conditions. By both methods, the estimated flow rates are fairly similar. The graph at the end of the Attachment shows both the M. Burke re: Rte. 116 / Kennedy Dr. sewer pipe; February 9, 2001; Page 3 high and low end of this range of estimated flows, for each time the liquid level was measured. Summary: In summary, one week of automated monitoring of the liquid levels in the sewer pipe just north of the manhole in the intersection of Route 116 and Kennedy Drive (February 1 to 8, 2001) shows that 90% of the time, this pipe carries less than 20% of its flow capacity. The maximum instantaneous flows we recorded were about 50% of the pipe's capacity. Actual flow rates cannot be precisely determined from these liquid level measurements because the flow regime was not hydrologically uniform. However, using standard estimating formulas, we have estimated that the flow rates might have ranged from about 9 gpm during overnight hours, to about 500 to 600 gpm during high -flow times, to a single peak of approximately 950 gpm.

O'Brien Home Farm Development Stormwater Analysis and Plans Aft -a Ghent 2 STORMWATER ANALYSIS O'Brien Home Farm A stormwater runoff analysis was performed on the proposed development at the O'Brien Home Farm in South Burlington. The site is generally bounded by Kimball Avenue to the north, Old Farm Road to the east, Hinesburg Road and existing homes to the south, and Kennedy Drive and several condominium developments to the west. The overall project will consist of an area of townhouse style units and an area of multifamily units. A town road from Kennedy Drive to Hinesburg Road will serve the development. Several private roads and drives will serve the individual units. There are a variety of existing soil types on the site including Adams -Windsor sands, Farmington - Stockbridge rocky loam Duane and Deerfield soils, Belgrade and Eldridge soils, and Enosburg- Whatley soils. These soils range from classified as type A to type C soils by the U.S. Soil Conservation Service, indicating a low to moderately high degree of runoff. The site slopes from east to west, at times steeply. The pre development condition was divided into five watersheds corresponding with the natural stormwater discharge points of the property. Study point 1 is located at the intersection of Kennedy Drive and Kimball Avenue; Study point 2 is a culvert crossing under Kennedy Drive north of Windridge Condominiums; Study point 3 is a culvert crossing under Kennedy Drive south of Windridge; Study point 4 is the where Wetland A exits the property, near Wellsley Grove Condos; and Study point 5 is the southwest corner of the property in a swale along Hinesburg Road. All of the proposed development occurs in areas discharging to Study points 3, 4, and 5. The runoff outleting to Study points 1 and 2 is unchanged. An elaborate network of swales, catch basins, piping, and extended detention ponds has been designed to treat stormwater and limit post development runoff to pre development conditions. Extended detention Pond 1 is located east of the new road near Hinesburg Road. This pond will treat and detain the majority of the runoff from the townhouses and 800 feet of the new road. Extended detention Pond 2 is located west of the new road near the Georgetown development. This pond collects and treats runoff from 600 feet of new road and the northeast corner of the townhouse area. Extended detention Pond 3 is located east of the new road near Kennedy Drive. Pond 3 collects the majority of runoff from the multifamily area and 400 feet of new road. Areas of the development flowing to Study points 3, 4, and 5 without being directed to a detention pond are treated via a combination of overland flow over vegetated terrain and grass lined swales. To determine runoff and size the new extended detention ponds the 25 year 24 hour storm event was used. This corresponds to a 24 hour rainfall event and 3.85 inches in Chittenden County. The watersheds were analyzed using TR-55 methods and Haestad Methods PondPack v7 software under pre development and post development conditions. The results were as follows: Page 2 25 YEAR STORM Study Point Pre Development Peak Runoff (CFS) Post Development Peak Runoff (CFS) 1 0.5 0.5 2 2.4 2.4 3 4.4 3.5 4 1.5 0.6 5 5.8 1.6 All post development peak runoff has been reduced to or below pre development levels. In addition to detention and reduction of peak runoff, the extended detention ponds have been designed to comply State of Vermont Best Management Practices for treatment of stormwater runoff. As such, the ponds will: a) collect the first inch of stormwater runoff from the site and release it over a period of 24 hours or more; b) be a wet pond with a permanent pool; c:) have side slopes of 3H:IV; d) contain an 18" sump for sediment collection and storage. homefamwormmo O'Brien Home Farm - Pre Development Stormwater Network Prey Pre4 Pre3 Pr e2 Pre1 A S A 4 A 3 A Z A I d A A A A PreSout Pre4out Pre3out Preiout Prelout Job File: C:\HAESTAD\PPKW\00182\HOMEFARM\HF-PRE3_PPW Rain Dir: C:\HAESTAD\PPKW\RAINFALL\ -------------------------- -------------------------- JOB TITLE -------------------------- -------------------------- O'Brien Home Farm -Pre development S/N: A21FO1106A8B Krebs & Lansing Cons Eng PondPack Ver: 7.0 (325) Compute Time: 08:42:56 Date: 03-06-2002 Table of Contents i Table of Contents ******************** NETWORK SUMMARIES ********************* Watershed....... 25 Executive Summary (Nodes) .......... 1.01 ****************** DESIGN STORMS SUMMARY ******************* chit-25yr.......

O'Brien Home Farm August 9, 2001 Page 1 INTRODUCTION The purpose of this evaluation is to determine the potential traffic congestion and safety impacts of the proposed development of 101 residential units on the O'Brien Horne Farm parcel which is located in the southeast quadrant of Kennedy Drive and Hinesburg Road. This project will develop the northerly portion of that parcel, and will construct a loop road with accesses onto both Hinesburg Road and Kennedy Drive. More specifically, this evaluation will: • Project present and future background design hour traffic volumes along Hinesburg Road and Kennedy Drive south and east, respectively, of their intersection. • Determine the existing and future vehicular trip generation of the project. • Evaluate whether this project will create unreasonable traffic congestion conditions. • Examine existing safety conditions, and evaluate this project's potential impact upon those conditions. PROTECT DATA The O'Brien Home Farm development is being proposed as a planned unit development. The present configuration of those units includes 45 three -bedroom condominium units plus 56 two - bedroom condominium/apartment units, for a total of 101 units. Access will be via a loop road which will access onto Hinesburg Road opposite Hayes Avenue and onto Kennedy Drive just east of Georgetown Condominiums. This road will also be known as Hayes Avenue, and will be built to city standards with curbs and a parallel recreation path. While the Hinesburg Road access will provide unrestricted access, the Kennedy Drive access will be restricted to only right -turn entering and exiting movements. At the two access points for this project, Hinesburg Road is under the jurisdiction of VTrans as Vt. Route 116 and Kennedv Drive O'Brien Home Farm August 9, 2001 Page 2 is under the jurisdiction of the City as a Class 2 town highway. Kennedy Drive has also been designated as a connector link in the National Highway System (NHS). BACKGROUND TRAFFIC VOLUMES Background traffic volumes for this study were obtained from several sources. At the Kennedy Drive / Hinesburg Road intersection, a turning movement count had been most recently performed by McFarland Johnson on November 14, 2000 as part of their engineering design work associated with the proposed reconstruction of Kennedy Drive. At the Hinesburg Road / Hayes Avenue intersection, a new turning movement count was performed by this office on July 9 & 10, 2001. Copies of peak hour summaries for both counts are included as Attachment A. For traffic studies such as this, the design hour volume of the highway is used to determine its capacity and corresponding level of service. The design hour volume (DHV) is defined as the 30`h highest hour of traffic volumes which occur annually. To calculate the DHV, typical practice is to apply what is known as the "K-factor" to the annual average daily traffic volumes (AADT), and factor up the peak hour turning movement volumes at each intersection accordingly. Attachment B presents the DHV calculations and resulting background DHV turning movements at the two aforementioned intersections. PROTECT GENERATED TRAFFIC An estimate of this project's vehicular trip generation was developed using using ITE trip generation rates for residential land -uses'. Although the proposed three -bedroom condominium units could justifiably be categorized as condominiums under ITE land use code #230, they were instead treated as single-family dwellings under ITE land use code #210. Table 1 summarizes the ' Trip Generation, Institute of Transportation Engineers, 6"' Edition O'Brien Home Farm August 9, 2001 Page 3 estimated vehicular trip generation for this project.

TRAFFIC CONGESTION The potential traffic congestion impacts of this project were determined by performing intersection capacity analyses at each intersection. The methodology used to evaluate traffic congestion is outlined in the Highway Capacity Manual'- (HCM). The HCM uses "level of service" to define traffic congestion. There are six levels of service, ranging from A to F. The criteria for each level of service at urban intersections are outlined in Table 2. 2 Special Report P209 - Highway Capacity Manual, Transportation Research Board, 1997 O'Brien Home Farm August 9, 2001 Page 4 TABLE 2 Level of Service l .riterin - Tnrnrcar-r;nr,c Level of Service Avg.

With engineering design for the proposed Kennedy Drive reconstruction underway, analyses were also performed at that intersection using both existing and proposed geometrics. Tables 3 and 4 present the results of the capacity analyses at each intersection. The results provide projected levels of service and average vehicular delays for approach plus the overall intersection. Detailed results are enclosed in Attachments E J.

The above results indicate that although the Kennedy Drive / Hinesburg Road intersection is presently experiencing congestion primarily during the morning peak hour, the Kennedy Drive reconstruction project will correct that. With those improvements, the O'Brien Home Farm PUD will not reduce future overall levels of service at this intersection.

The level of service results at the Hinesburg Rd. / Hayes Ave. intersection indicate that future levels of service will remain well within acceptable ranges, even with the proposed development of the O'Brien Home Farm. On Kennedy Drive, where the project access (Hayes Ave.) intersects, detailed capacity analyses were not performed due to that proposed access being restricted to right -turn movements only, which typically do not experience significant delays. TRAFFIC SAFETY Vehicular traffic safety is influenced by many factors, including road width, pavement conditions, sight distances, lighting, proper signing and pavement markings, speed limits, alignment, number and spacing of driveways, etc. The following discusses several of the more important factors with respect to conditions on the adjacent street network in the immediate vicinity of the shopping center. The existing speed limit on Hinesburg Road in the vicinity of the project is 35 mph. This speed is consistent with the alignment and function of the roadway, particularly given the developed O'Brien Home Farm August 9, 2001 Page 7 nature of the area. Sight distances at both proposed intersections onto Kennedy Drive and Hinesburg Road also exceed the recommended minimum of 385 ft. at 35 mph. Five year accident histories were obtained from VTrans for both Hinesburg Road and Kennedy Drive. From 1995 through 1999, 10 accidents were reported at the intersection of those two streets, 4 accidents on Kennedy Drive between Hinesburg Road and Kimball Avenue, and 5 accidents on Hinesburg Road between Hinesburg Road and Old Farm Road. Considering the function of these roads and their traffic volumes, the foregoing accident history is not indicative of any serious or inherent traffic safety problems. Conflicts at intersections caused by turning vehicles also can influence traffic safety conditions. To minimize such conflicts and preserve the efficiency of through traffic flow, warrants have been established concerning exclusive left- and right -turn lanes at intersections by VTrans. Those warrants were examined at the Hinesburg Road / Hayes Avenue intersection, with the results indicating that exclusive left -turn lanes will be warranted on both the northbound and southbound Hinesburg Road approaches. The calculated storage lengths equal 75 feet in the southbound direction and 100 feet in the northbound direction. Right -turn lanes were found not to be warranted. Copies of the left -turn lane warrant analyses are included as Attachment K. With the proposed access onto Kennedy Drive being limited to only right -turns using a slip -ramp intersection configuration, there will not be a need for any exclusive turn lanes at that location. It is recommended, however, that consideration be given to installing a physical median in Kennedy Drive at this location so as to prevent any possibility of unauthorized left -turn movements. CONCLUSIONS This evaluation has determined the potential traffic congestion and safety impacts resulting from the proposed O'Brien Home Farm PUD. The following outlines our conclusions relating to O'Brien Home Farm August 9, 2001 Page 8 background traffic congestion and safety conditions and this project's potential impacts upon those conditions: ► The existing street network (Kennedy Drive and Hinesburg Road) will have sufficient capacity to serve the additional traffic which will be generated by this project once the Kennedy Drive reconstruction project is completed. Because this project is phased, the full impacts of this project, as presented in the foregoing sections, will not be realized until build -out. ► Existing traffic safety conditions along Hinesburg Road and Kennedy Drive in the immediate vicinity of this project are typical of a developed urban area, and do not indicate the presence or potential for this project to create any adverse traffic safety impacts. ► It is recommended that in addition to the highway impact fee which will be required of this project to mitigate off -site traffic impacts, that exclusive left -turn lanes be constructed on Hinesburg Road at Hayes Avenue to serve this project. It is also recommended that the Kennedy Drive access be configured for right -turn movements only, and that a median be provided to prevent unauthorized left -turn movements.

South Burlington, VT116, L.S. 159+32 October 3, 2001 SPECIAL CONDITIONS All work shall be accomplished in accordance with the attached plan dated August 14, 2001. Act No. 86 of 1987 (30 VSA Chapter 86) ("Dig Safe") requires that notice be given prior to making an excavation. It is suggested that the Permit Holder or his/her contractor telephone 1-888-344-7233 at least 48 hours before, and not more than 30 days before, beginning any excavation at any location. Any work done within the highway rights -of -way that is not addressed by the included plans will be done according to the Vermont Agency of Transportation 2001 Standard Specifications for Construction, with the latest amendments and all applicable VTrans Standards. The Permit Holder shall use methods that will minimize tracking of material onto state highways. If tracking does occur, it will be immediately cleaned up so that traveling conditions and safety of highway users is not compromised. A preconstruction meeting must be held prior to the Permit Holder's employees or contractor beginning work to discuss work to be completed. The Permit Holder is required to notify the District Transportation Administrator five (5) working days in advance of such meeting. The Permit Holder is to have a supervisory representative present any time work is being done in or on the State Highway right-of-way. Roadway shoulder areas will be maintained free of unnecessary obstructions, including parked vehicles, at all times while work is being performed under this permit. All grading within the highway right-of-way associated with the proposed construction shall be subject to inspection and approval by the District Transportation Administrator or their staff. In areas to be grass covered, the turf shall be restored by preparing the area and applying the necessary topsoil, limestone, fertilizer, seed, and mulch to the satisfaction of the District Transportation Administrator. Page Two All work in the State highway right-of-way shall be performed during normal daylight hours and shall cease on Sunday, on all holidays (which shall include the day before and the day following), during or after severe storms, and between December 1 and April 15, without specific, written permission from the District Transportation Administrator. These limitations will not apply for the purposes of maintenance, emergency repairs, proper protections of the work which includes, but is not limited to, the curing of concrete and for the repairing and servicing of equipment. Temporary pavement will be required prior to weekend shutdown after completion of backfilling where an open cut excavation has been made through a roadway subject to vehicular traffic or where construction for any roadway widening for turn lanes has been brought to grade. The temporary pavement shall consist of, at least, 2 inches of compacted bituminous concrete. Temporary pavement shall be properly maintained and shall be replaced with permanent pavement prior to completion of the project or suspension of work for the winter season. (This is a contingency condition in the event the "open cut method" is approved during construction.) The placement, size, shape, and color of all pavement markings will be in accordance with the Manual on Uniform Traffic Control Devices and Vermont Standards. All existing pavement markings that become disturbed or overlaid with pavement shall be replaced with "in kind" (durable or paint) markings. All costs associated with this work shall be borne by the Permit Holder. The Permit Holder shall be responsible to rebuild, repair, restore and make good all injuries or damage to any portion of the highway right-of-way that has been brought about by the execution of the permitted work, for a period of eighteen (18) months after final inspection by the District. Any variance from approved plans is to be recorded on "as-builts" with copies provided to both the Utilities Engineer and the District Transportation Administrator. Upon completion of the work by the Permit Holder, a final inspection will be held. The Permit Holder shall be responsible for all damages to persons and/or property due to or resulting from any work allowed under this permit. The Permit Holder shall defend, indemnify and save harmless the State, the Agency, and all of their officers, agents, and employees from all suits, actions, or claims of any character, name and. description brought for or on account of any injuries or damages received or sustained by any person, persons or property, including all costs or expenses to defend against such suits, actions or claims. Page Three This permit does not become effective until the Owner/Applicant records, in the office of the appropriate municipal clerk, the attached "Notice of Permit Action". The access must be constructed in such a manner as to prevent water from flowing onto the highway. If the access is not constructed satisfactorily, the District Transportation Administrator can order reconstruction of the access at the Owner's ex- pense. This access will serve as the only access to this property and to any future subdivisions of this property unless approved otherwise by the Vermont Agency of Transportation. Curbing or other suitable physical barriers must be installed to control ingress and egress of vehicles to the approved access only. In the event traffic from this project increases to the point where traffic signals, additional lanes for turning or any other modifications are necessary, the expense of such improvements or facilities shall be borne by the Permit Holder, his/her successors, and assigns. The Permit Holder may be required by the Agency to update or provide a traffic study to determine if additional modifications are necessary. The Permit Holder is responsible for access maintenance (beyond the edge of paved shoulder). "Access maintenance" will include, but not be limited to, the surface of the access, the replacement of the culvert, as necessary, the trimming of vegetation, and the removal of snowbanks to provide corner sight distance. In conformance with Title 19 VSA § 1111(0, this access may be eliminated in the future where development has burdened the highway system to such an extent that a frontage road or other access improvements (which may serve more than one property or lot) must be constructed to alleviate this burden. The expense of the frontage road or other access improvements shall be borne by the Permit Holder, his/her successors or assigns of the properties abutting said frontage road or served by the access. The Agency of Transportation shall determine the need of a frontage road or other improvements based upon and justified by standard Agency procedures. The highway crossing shall be installed by jacking or boring in accordance with the attached standard D-20. Open trenches or pits shall be filled at the end of each day. With permission from the District Transportation Administrator, trenches and pits may be left open for short periods of time if properly protected. In no case shall trenches or pits be left open over a weekend. Page Four Where a trench is excavated within the roadbed, all backfill material within 24 inches of the bottom of pavement shall be new material from a source approved by the District Transportation Administrator. All backfill material shall be placed in six inch layers and compacted to not less than 95% of the material's maximum dry density as determined by AASHTO Standard Method of Test, T-99, Method C, using air or mechanical tampers. (This is a contingency condition in the event the "open cut method" is approved during construction.) It is incumbent upon the Permit Holder to verify the appropriate safety measures needed, prior to construction, so proper devices and/or personnel are available when and as needed. Traffic control devices, shall be in conformance with the MUTCD (Manual on Uniform Traffic Control Devices), Agency of Transportation Standards and any additional traffic control deemed necessary by the District Transportation Administrator. Failure to utilize proper measures shall be considered sufficient grounds for the District Transportation Administrator to order cessation of the work immediately. Construction will be performed in such a way as to minimize conflicts with normal highway traffic. Uniformed traffic officers or trained flagpersons, shall be provided when two-way traffic cannot be maintained, and at the request of the District Transportation Administrator whenever it is deemed necessary for the protection of the traveling public.

In response to your letter dated 11-6-01 we offer the following: Intersection of Hinesburg Rd. & Kennedy Drive The background volumes at this intersection have been revised using year 2000 growth factors. We have reviewed the traffic study which was completed for Technology Park. That traffic impact report, which included all phases of that proposed development, estimated that only 10% of project traffic would pass through the intersection of Hinesburg Rd. & Kennedy Drive. The recently permitted Lots 2 & 7 have been approved for a combined 172 p.m. peak hour trip ends and 179 a.m peak hour trips. This will result in an additional 18 trip ends through the intersection of Hinesburg Rd. & Kennedy Drive. These trips have been distributed based on information given in the initial traffic impact report for Technology Park. We have revised the 2006 capacity analyses for this intersection (existing geometry). Arrival type 3 was used for analyses without Kennedy Drive improvements. These analyses were completed using protected plus permissive left turn phasing. Table 1 shows that it is possible to achieve adequate levels of service at the intersection without planned Kennedy Drive improvements.

However, the actual phasing of the project will be market driven. As shown above, it is possible to achieve adequate levels of service at full build out, eliminating the need for interim capacity analyses with alternate phasing. Intersection of Hinesburg Road & Hayes Avenue The background volumes at this intersection have been revised. Previous analyses assumed that the ATR counter on Hinesburg Rd. south of Kennedy Drive was north of Hayes Avenue (worst case scenario). The DHV factor has been revised to show the ATR counter as being south of Hayes Avenue. This resulted in a lower DHV factor. Year 2000 growth factors were then applied to bring the count to 2006 DHV. Hayes Avenue is primarily an access to a residential development. Growth factors were not applied to traffic entering and exiting Hayes Avenue as the number of resident's in this development is not likely to increase with time. The only trucks observed during the p.m. peak hour of the L&D count were traveling through the intersection on Hinesburg Road. The left turn lane warrant has been recalculated using the revised background volumes. The warrant is still met in both the northbound and southbound directions on Hinesburg Road.

This project has one access onto Kennedy Drive and one onto Hinesburg Road. The Hinesburg Road access is directly across from Hayes Avenue. There is currently a southbound right turn lane on Hinesburg Drive for cars turning onto Hayes Avenue. We are proposing to eliminate this southbound right turn lane, as the right turn lane warrant is not satisfied. The northbound and southbound left turn lane warrants at the intersection of Hayes Avenue & Hinesburg Road were both met. We have enclosed for your review and conceptual approval, a sketch of the left turn lane design as well as supporting calculations.

Box 2184 South Burlington, VT 05407 Subject: Home Farm wetland delineations Dear Pat, I delineated the wetlands on the Home Farm parcel on 3 November, and Arthur Gilman and I completed the Corps of Engineers data forms for the project (enclosed) on 14 November. There are three wetlands in the area proposed for the project; all are in drainage swales on the Kennedy Drive side of the property. These wetlands, designated "A", `B" and "C" are in well-defined shallow ravines. These three wetlands are along drains that eventually lead to Potash Brook, passing across a large expanse of poorly to very poorly drained Enosburg & Whatley soils. There is an extensive Class Two wetland along Potash Brook, and it is conceivable that wetlands on the Home Farm site might be connected across Kennedy Drive to those Class Two wetlands. I will try to determine if we are dealing with Class Two or Class Three wetlands this afternoon while in the area on another project, and will contact you once I have visited the site.

Landscaping The required landscape budget based on the South Burlington ordinance for lot 2 (Lancaster Place) is $35,035. The plans indicate value exceeding this amount. The apartment area, the retention of vegetation in the natural open space, and the buffer will contribute additional value to the landscaping. Plants were chosen that are salt tolerant and disease resistant. No invasive plants are specified and plant material native to Vermont make up a large percent of the specified plants. Lancaster Place is surrounded by existing vegetation to remain. Plantings are predominantly shade trees to bring down the scale of the 2-'/2 story buildings and to provide amenity for the residents. Many flowering trees are introduced in the newly cleared open spaces formed by the buildings. Within Stonington Circle the grading has been held back along the north lot line adjacent to the Wellesley Grove Townhouses to retain as much of the existing vegetation as possible. Supplemental planting is proposed in this area to insure privacy of neighbors as shown on L4. Street trees are specified at 2" rather than 2.5" and spaced at 35' on center rather than the city requirement of 60' on center for subdivision streets. The closer spacing of the trees will provide a greater aesthetic benefit, and mitigate the larger caliper size required by the city. Planned street trees are in a "greenbelt" of 7 to 8 feet between the bike path and the curb and all tree pits will be three times the diameter of the root ball. Species have changed from the preliminary design to include Green Ash, Red Oak, Red Maple in addition to Littleleaf Linden as previously shown on the plans. All trees have proven to be reliably salt tolerant and are spaced to accommodate streetlights. H. Site Aesthetics. The site plan was developed to provide an architecturally pleasing arrangement of solid and void arranged around a clear circulation system of roadway and paths. Simple loop systems provide ready access to units, which are oriented to private spaces behind. The plan was arranged to provide for future development to the east as part of an overall plan. T3. Boyle and Assoc iates• Landscape Arc hitects• Planning Consultants Planting is designed to enhance the architecture, provide solar relief and allow solar gain, and structure open space and privacy while providing an attractive setting for resident's enjoyment. Street lighting along the city street is proposed to be cut-off fixtures located at all intersections and driveway entrances, at a mounting height of 13 %2 feet. Fixtures in the apartment area are mounted at a height of 20' to help achieve a better -lighted area with uniformity ratios compliant with the Outdoor Lighting Manual for Vermont Municipalities. All fixtures will have cut-off characteristics to reduce glare and direct illumination away from units and the property perimeter. 1. Open Space The project provides a diversity of open space and recreational opportunities. A bike path along the public streets will not only benefit residents of the proposed development, but also create a pedestrian connection from existing developments in the Hayes Avenue area to those along Kennedy Drive. Significant open space associated with intermittent streams and wetlands provides for a natural area recreation experience in a wooded setting. Lot 3 will remain entirely in its natural condition. Opportunities exist for informal hiking that will connect to future open space components of later developments on the O'Brien Home Farm. T3.
