Spitz, City Planner Re: Dubois Subdivision Application Date: 7/26/83 Homer and Jackie Dubois have submitted a subdivision and planned development application for 62 single-family lots, eventual construction of 110 multi -family (townhouse) units, and an agricultural open -space system. The site is approx- imately 86 acres and is located north of Highland Terrace, east of Hinesburg Road, and south of Ralph Goodrich's property which in turn is south of Mitel. The applicants also own land west of Hinesburg Road but are not proposing develop- ment on that parcel at this time. REVIEW PROCEDURE. Zoning for the Agricultural and Rural Residential District allows development at 2 units per acre if a lot is greater than 50 acres in size, if public sewer and water are provided, and if both City Council and Planning Commission grant approval. The first two criteria can be satisfied. There is no clear precedent for the third criteria, i.e. procedure for the City Council's review. I would suggest the following: 1) Sketch plan review, at which no formal action is taken, should be under- taken jointly by both City Council and Planning Commission. 2) Both preliminary and final plat reviews require that approvals be granted. The public hearings may or may not be held jointly, as desired, but deliberations and motions of approval or denial should take place separately. Since the Planning Commission is more familiar with the details of development review, I recommend that its action take place before the City Council's at both preliminary and final stages of review. 3) Preliminary plat review by both bodies should focus on overall layout issues and the general planned development criteria (section 6.502 and 19.161). Engineering matters and other specific details should be reserved for final plat review. AGRICULTURAL LAND. The entire agricultural land issue in the State of Vermont is still quite confused. However, Act 250 still does have anagricultural soils criteria, and South Burlington has an agricultural policy in effect which it can apply as deemed appropriate in specific development applications. This property in combination with Goodrich's land has received conceptual approval from Act 250 for a scheme that will retain some agricultural open -space. In contrast, South Burlington's policy would require no agricultural land on Goodrich's industrial property and instead would require a larger open space concentration on Dubois' land. The preferred arrangement is to combine Dubois' two parcels and to reserve all open space on the west side of Hinesburg Road, however, the applicant has been reluctant to accept this arrangement. The amount Of topsoil that he has stripped does not make it easier to satisfy any of the agricultural land schemes. Memorandum Dubois Subdivision Application 7/26/83 Page 2 3 In sum, the City Council and Planning Commission must consider two points: (1) how seriously it wishes to pursue any agricultural preservation scheme, and (2) what layout best satisfies the agricultural land concepts that the City chooses to apply. OTHER ISSUES . Since water and sewer will be extended, proposed lots necessarily are much smaller than existing lots in the area. Compatibility in terms of buffers, street connections, etc. should be considered. Street layout.incudes an unusually large number of cul-de-sacs. Street department and/or City Engineer should review this arrangement. Utilities will be extended. Capacity of the sewage treatment plant must be guaranteed at the appropriate stage of review. Further utility extensions must also be made available.

Eileen Bradley, Merrill Theatres; William Schuele, David Willis, Nancy DeForge, Funding Request - Special Services TRansportation Agency Wayne DeForge explained that they were growing faster than their resources and had thus reorganized their service. Some vehicles and personnel had been eliminated, and the criteria for trans- porting persons had been changed. They will be receiving 3 fully equipped vans through a federal subsidy with only a pay- ment of $2,000 each as a token. They are asking for the same budget'as last year.

He explained that what was needed now was a Finding of Fact that all criteria have been met and also a motion of approval. Mr'. Farrar then moved that the City Council find that the proposed development: CITY COUNCIL March 5, 1984 page 2 Will not resul-; in undue water or air pollution, as the development will be'served by. -City sewers. b) The development has sufficient water available for the foreseeable needs of the development, as it will be served by City water provided by the Champlain Water nistrict c) It will not cause unreasonable soil erosion, as presented in the plans and as will be presented to the Planning Commission d) It will not cause unreasonable highway congestion. Infor- mation presented to the City Council indicated that there was no highway congestion to be expected e) It will not cause an unreasonable burden on the ability of the City to provide educational services. A letter from the school system testifies to this. f) It will not cause an unreasonable burden on the City to provide municipal or governmental services. There was no evidence in the record to indicate there are any unusual services to be provided for this development. g) It will not cause undue adverse effect on the scenic or natural beauty of the area. There are no areas within the de- velopment which have been designated areas of specific scenic or natural beauty. h) Will provide housing types, costs and characteristics appropriate to the housing needs of various social and economic groups. It has been pointed out that areas where the community is lacking is the availability of single family lots. In the total development, one half the lots to be provided are single family. i) Will provide for convenient allocation and distribution of common open space as was shown in the plan presented j) Will provide efficient lay -out and high -quality installation and construction and maintenance of streets and public facilities and will conform with the City's utility plan. Tliis item will be covered under the final review of the Planning Commission. k) Will provide cooperation with adjoining properties in the extension of roadways, drainage facilities and utility lines. provide the maxirmim potential for energy conservation. This item will be covered in the final approval of the Planning Commission. m) Will conform with the Cbmprehensiv�� Plan of the City. I CITY COUNCIL March 5, 1984 page 3 These items have been, or those which have not been will be com- pleted in the final approval of the Planning Commission. Mr. Peters seconded the motion which passed 3-1, Ms. Lansing voting against. Mr. Farrar then moved that the South Burlington City Council approve the p anne unit development application of Horner and Marie Dubois for a 54 unit single family development and a 53 acre multi -family development as depicted on a plat plan entitled "Ledge Knoll Subdivision" prepared by Trudell Consulting En ineers, Inc., dated November 16, 1983, with revisions dated 12�30/83 and 1/18/84, subject to the following stipulations: 1) that approval as granted is for the entire concept with phase I being 57 single family units and phase II being 69 town house units 2) that all existing overhead power be constructed underground, which shall include the removal of all existing power poles 3) that Highland Terrace be extended to Dubois Drive after fifty (50) units are completed within this development 4) That the set -back requirements be established at final plat approval by the Planning Commission; however, those set -backs shall be no less than those set forth within the Residential 2 District 5) that the Planning,Commission give serious consideration to closing Highland Terrace at Hinesburg Road if and when this development is connected to the Green Acres development 6) that the housing design be of differing variations within a construction price range of 75 to 85 thousand dollars 7). that bonds for all streets and waters for the single family phase be posted prior to the start of construction 8) that all open space shall be held in common by-' of the lot and condominium owners and that the land in these common areas cannot be sold unless all owners approve 9) that any residual development rights for the common land be deeded to the City. Mr. Peters seconded the motion. Ms. Lansing asked how much open space was in the total area. Mr. Farrar said approximately 1/3 of the total land development was agricultural corridor and wooded area. CITY COUNCIL March 5, 1984 page 4 In the vote which followed, the motion passed 3-1, with Ms. Lansing voting against-. Mr. Farrar asked Ms. Lansing the nature of her objections to the motions. Ms. Lansing said she did not like the loss of agricultural land and felt they were giving up too much for development. She also didn't like the development so far away from city services. Mr. Farrar noted that the sewer allocation is only for the single family homes. Review Sign Ordinance Committee report and consider amendments to ordinance The findings of the Sign Ordinance Committee were noted�(attache3). Mr.Mi l!J. rsaid they were pleased to have served and that their primary recommendation was not to change but to better enforce the ordinance. Mr. Farrar said he agreed with the recommendations as set forth and that the major consideration was the clarification of the status of nor -conforming signs. He felt that those which exist, as long as they exist in their present form, will be taken care of eventually. If those with non -conforming signs could be encouraged to come closer to conformity, it would be a good idea. Discussion was continued until the next meeting when further information from the City Attorney would be available. Ms. Lansing then moved that the Sign Committee be dissolved with thanks for their efforts. Mr. Farrar seconded with unanimous approval. Funding Request - Visiting Nurse Association Betsy Davis introduced Samual Bogorad, South Burlington's new representative on the Board of Directors. Ms. Davis thanked the City for past support and for considering an increase for this year. She noted the increasing aging population, noting that of the 80% increase in services in South Burlington 40% was to those over 75 years of age. They have suffered federal cutbacks and from pressures from hospitals which are releasing patients earlier or not admitting them at all. Critical items include handicapped transportation, the waiting list for home- maker programs. She felt that without added funds, patients will be harmed. Mr. Bogorad cited two instances in which he had observed the work of VNA at close range and had found it a most heartwarming experience. He said he had never been touched so much by anything since he had. come to South Burlington... and was equally moved by what VNA could not do because of lacK of funding. Mr. Farrar said they would try to weave as reasonable an increase as possible into the budget. He felt it could save money in the long run on insurance premiums. PLANNING COMMISSION MAY 29, 1984 The South Burlington Planning Commission held a regular meeting on Tuesday, May 29, 1984 at 7:30 pm in the Conference Room, City Hall, 575 Dorset St. Members Present Sidney Poger, Chairman; Mary -Barbara Maher, John Belter, Judy Hurd, William Burgess, Peter Jacob Others Present Jane Bechtel, Planner; Richard Ward, Zoning Administrator; James Lamphere, Daniel & Leo O'Brien, Kathleen & Jeff Davis, Steve Moore, Karen Critchlow, Nancy Cote, Doug Ireland, Ray Delaney, Constance Snyder, Rosemary & V.H.

On page 3, in the last paragraph, the following changes should be made: in the fourth line, "they" should read "the Planning Commission", the sentence beginning with "Mr. Heindel" should read that "... the Planning Commission can ask developers...", and the sentence beginning with "He added" should read that "... it would be possible for developers to submit information to Wagneri,Heindel, and Noyes on the development...." Mr. Burgess moved to approve the May 22, 1984 minutes as corrected and Mrs. Maher seconded the motion. All voted in favor. Public hearing on revised preliminary plat application of Daniel O'Brien, for Cardinal Woods Extension, a 107 unit planned development located on Hinesburg Road Mr. Dan O'Brien noted that he had been before the Commission before and that he had obtained preliminary plat approval for 180 units. In reviewing those approved plans, though, it was felt that the density was too high, so they are now requesting 107 units. This will allow for a mix of single family homes, condominiums, and zero lot line homes. Mr. Poger pointed out that a 5' side yard might be better than a zero lot line, since that would allow room for painting the house or other routine maintenance. Mr. Lamphere explained the plan. Hayes Avenue will be picked up and hooked to Hinesburg Road. They would like to separate the two lanes of the street with a25' wide berm with landscaping. The lanes will be 15' wide. They would like to curb only the outermost part of the road. Some concern was expressed about the berm being driven on and Mr. Lamphere mentioned putting gravel areas between the berm and. the road. The other development roads will be private and 24' wide. Mr. Doug Fitzpatrick said they would hook to the existing 12" water main on Hinesburg Road and tie to the line in Cardinal Woods. Sewer will flow by gravity to the Cardinal Woods sewers. Mr. Poger asked the developers to check with the City Manager regarding his memo on the gravel base for the -private roads. Mr. Larry Chetti said he was an adjacent landowner and that there was a low spot on his land that he wanted to be sure would still drain after the 2. PLANNING COMMISSION MAY 29, 1984 development was built. He also asked about screening and was told none was planned 'because the units on both sides of the property line would be of the same type. Mr. Chetti asked whether provisions could be made to accomodate him with utilities in case he developed his land in the future. Mr. Fitzpatrick said that could be done if specific directions were provided. Mr. Chetti asked about access to this development's road network for his future development, but was told the Commission could not force the developer to provide that, although it could ask that such access be left. Ms. Bechtel went through the points noted in her 5/25 memo on this development. Mr. O'Brien noted that when Country Park was constructed, the developers took the sidewalk length equal to the property frontage and slid it down so it would start at Kennedy Drive, instead of running the length of the Country Park frontage and leaving a gap at the corner. Now they have that same gap to deal with. The Commission agreed that this sidewalk should be hooked to the end of the Country Park sidewalk, even though it will again leave a gap when done. Mr. Lamphere asked for a reaction on the divided street. Mr. Poger said the Commission liked the idea and that unless a specific reason were given for needing curbing on the inside next to the berm, the Commission probably would not require it. He said it could be looked into and the developers told if the Commission changed its mind. Mrs. Hurd asked about the deceleration lane and was told the developers wanted to do some further engineering before they decided whether or not that was needed. Mr. Poger felt that if the Commission had required it last time, they would probably require it again. Mr. Jacob moved that the South Burlington Planning Commission approve the Preliminary Plat Application by Daniel J. O'Brien for a 107 unit planned develop- ment on Hinesburg Road as depicted on a plan entitled "Utilities/Preliminarzt Cardinal Woods Extension". prepared by Wi emann- Lamphere Architects dated 22 1.

The applicant shall provide a recreation fee of $200 per unit or �21,400. The fee may be paid on a per, unit basis. 3. PLANNING COMMISSION MAY 29, 1984 7. An erosion control plan and drainage plans shall be presented to the Commission for its approval at Final Application. 8. A construction schedule shall be provided and approved by the Commission at Final Application. 9. The Fire Chief's concerns regarding gravel access roads, hydrant location and installation of hydrants along Hinesburg Road shall be included n the Final Application. 10. Parking shall be provided in the amount of 2 spaces per unit plus "visitor" parking in the amount of 1 space per 6 units in reasonably close Droximity to the units being served. 11. The sewer allocation shall be 33,450 gallons per day based on 67 single family units and 40 multi -family units. 12. This approval will expire 12 months from this date. Mrs. Maher seconded the motion. Ms. Bechtel felt it should be noted that the previous sewer allocation for this project was null and void. It expired recently and this is now considered a separate and new project. Before the motion was amended, there was a stipulation reading "House and yard lines shall be designated at Final Application." Mr. O'Brien objected to that, feeling it would give them less flexibility in the sizing of the homes. He said they would rather deal with that when they received their building permits. Mr. Poger felt the stipulation should be removed, but that at final plat the building envelopes should be shown and that specific plans should be submitted for each house, which will be approved by the Planner, at a later date. The motion carried unanimously. Chairman Poger ruled that the previous application of the O'Brien Brothers for the Cardinal Woods Extension and its sewer allocation have both run out and are therefore null and void. Site Plan Review for Jeff Davis for the-exansion at 1270 Shelburne Road and conversion to retail use Carters Clothing) Mr. Poger noted that this was a new hearing and that whatever had come up at the previous hearing was immaterial. Mr. John Fitzpatrick, attorney representing some neighbors, requested that the Commission ask the City Attorney whether or not the Commission had the right to overrule the court with regard to its findings on the maximum peak hour traffic counts. Mr. Poger repeated that this was a new proposal, which the Commission had to hear. He ruled that unless the other members wished to do so, he would not direct the above question to the Attorney. None of the members wished to ask the question. Mr. Moore, representing Mr.Davis, noted that the proposal included moving the building back so the front yard setback would be 55'. The existing building plus new construction would total 6500 sq. ft. 48 9' x 18' parking spaces are shown, with 2 handicapped spaces, and 3 for loading. Landscaping is mainly in the corner and a new hedge will be added to the west of the existing hedge to fill in the spaces. One 32' wide curb cut is proposed, 150' from Shelburne Rd. Lighting will be on 8' poles and will be down lighting. The parcel is 9/10 of an acre and building coverage is 65%- 4. PLANNING COMMISSION MAY 29, 1984 Mrs. Maher did not like the 4 parking spaces in front. Mr. Poger suggested that that area be graveled and grassed and the spaces paved later if it proved they were needed.

Public hearing on Final Plat Application for Homer and Marie Dubois for Ledge Knoll, a 57 single-family unit planned development, and 53 acres reserved for future use, located off Hinesburg Road Mr. Trudell represented the Dubois family. He said there had been no change in layout, but they had been unable to reach an agreement on a sewer easement with Mr. Goodrich, so they will have to run the sewer to Hinesburg Road and then north and into the Mitel easement. The only other changes are those requested by the Commission at the last hearing. The homes will be clustered and some land left open for agricultural use. The water main will be extended south from its present location, and storm drainage will be on - site. Street trees will be planted. The roads will be 30' wide with curbs and sidewalks on one side. They will be city streets. A connection to Highland Terrace is shown, and additional screening from the Toutant land is shown. Mr. Trudell asked that the phasing schedule be changed to allow 40 units in the first phase. They want to build over 2 years instead of the 4 originally planned. Erosion control was discussed and Mr. Cobb noted that they would not strip all the land at one time. It was noted that the figure for intersection signallization contribution was in dispute and Ms. Bechtel said she would double check it. Mr. Jacob moved that the South Burlington Planning Commission approve the revised Final Plat application by Homer & Marie Dubois for a Planned Unit evelo went as depicted on a 23 page plan entitled "Ledge Knoll Planned Unit Development" dated 11 16 83 and revised 12 30 83 and 1 19 84, as prepared by Trudell Consulting Engineers with the following stipulations: 1.

This approval will expire 3 years from this date. Mrs. Maher seconded the motion. Mr. Cobb noted that the applicant would just as soon deed the open land as well as the development rights to the city, in #9. Ms. Bechtel said the stipulation was intended to do two things. The open land would be held by the landowners, but the city wanted the development rights. Mr. Cobb said that when the back land was developed, they intended to deed the open land, the agricultural corridor and the wooded area to the Association. Until then, they want to keep the land other than the lots sold, in the Dubois name. It was noted that when the development was complete, the single-family lots would have an interest only in their own lots, while the condominium owners would have rights on the open space. Future development rights, such as those which would occur if the land were re -zoned, would be deeded to the city. The motion carried with all voting aye. Other business Ms. Bechtel said that she had been contacted by Queen City Park and Fire District #1 people. They want to have a public hearing sponsored by a city M-1 PLANNING COMMISSION MAY 29, 1984 body, in order to submit an application for a project development grant to the state to do an engineering study of the water system in Queen City Park to determine its useful life and replacement value. They also want a housing survey done, and want to know the best development of any recreation or common land. The deadline is June 15, so the Planning Commission is the only body which will meet in time to meet that deadline. Mr. Jacob moved to sponsor a public hearing on June 14 for Queen City Park Fire District #1 to submit a project development grant to the state. Mrs. Maher seconded the motion and all voted aye. Ms. Bechtel noted that she had vacation plans for the last week in June, and a Commission meeting is scheduled for that week. It was decided to wait until June 12 to make a decision on rescheduling the meeting, or having it anyway. Mr. Poger asked about several items on the Zoning Board agenda. He asked Ms. Bechtel to relay concerns on the bottle redemption center application about the number of uses on the property and the probability of increasing the traffic counts. The meeting was adjourned at 10:00 pm.

The Wellesley Grove water system is acceptable to this Depart- ment. All 24 units are metered, valves are grade level, curbstops and hydrants are acceptable. Before this project is deeded, how- ever, this Department requires a set of reproducible "as built" drawings. Ledgeknoll is also acceptable to this Department and a frontage contract has been signed by Homer Dubois and the Board of commission- ers. Mr. Dubois has already given me a set of Record Drawings.

The minimum distribution water main is 8 inch. 3. Sidewalks ahould be included along Hinesburg Road. 4. Private streets should include a gravel base 30 feet in width and bituminous pavement of 24 feet. 5. I would recommend that the water main located in the grassed median be re- located between the curb and sidewalk so that trees could be planted in the median strip. 6. The 60 foot right-of-way for the public street is not wide enough to allow for a future sidewalk along south side. The right-of-way should be 70 feet. 3) Shelburne Road Project (Carters), N.E. Corner Imperial Drive 1. Sidewalk along Imperial Drive should be constructed on property line. It must be continuous across the entrance drive. 2. Driveway shall include a depressed concrete curb with flairs instead of radii. 4) Ledge Knoll 1. It is unfortunate that a sewer easement can not be negotiated to run the pressure main directly north instead of the Hinesburg Road route. This adds approximately 2,000 more feet to the length and increased cost of energy to pump that extra distance. 2. There should be a manhole and stub at the intersection of Highland Terrace and Dubois Drive with stub extended beyond Dubois Drive to prevent damage to this street when the sewer is extended south to service Highland Terrace. 1'lUMC 11LJ1kIN(� SOU1111 BUR I NGIM PI ANN I.

PLANNING COMMISSION 4 4. MAY 29, 1984 Mrs. Maher did not like the 4 parking spaces in front. Mr. Poger suggested that that area be graveled and grassed and the spaces paved later if it proved they were needed. Mr. Fitzpatrick wondered if this could be considered a multiple use, since there will be retail space plus space for ancillary uses such as storage, but was told it was not considered a multiple use. Ms. Bechtel said the Commission had to decide whether to use ITE traffic counts, or other estimates, such as local data. Mr. Poger said he would like to have traffic information presented tonight, but have another meeting so the public could study the traffic information the Commission has on the project. Ms. Bechtel said Fitzpatrick -Llewellyn had studied 6 retail stores in the area. They had felt that the ITE category of specialty retail centers was not applicable, so they took some counts of their own. They eliminated the high and low stores, and came up with an allowable square footage of 6682. The City requested consultant David Spitz to review the study and he responded that he felt there should be some seasonal adjustment, which would bring the maximum allowable space to 6309 sq. f t. ITB figures would allow a size of 4,587 sq. f t. She noted that these were estimates, and were not absolutes. Mr. Roger Dickinson of Fitzpatrick -Llewellyn said they did not argue with Mr. Spitz, but he noted that they had done the counts on higher than average traffic level days within the week, if not at the high traffic season. Mr. Jacob moved to continue the hearing on the site plan review for Jeff Davis for two weeks, until June 12, 1984 at 7:30 pm at City Hall. Mrs. Maher seconded the motion and all voted for it. Public hearing on Final Plat Application for Homer and Marie Dubois for Ledge Knoll, a 57 single-family unit planned development, and 53 acres reserved for future use, located off Hinesburg Road Mr. Trudell represented the Dubois family. He said there had been no change in layout, but they had been unable to reach an agreement on a sewer easement with Mr. Goodrich, so they will have to run the sewer to Hinesburg Road and then north and into the Mitel easement. The only other changes are those requested by the Commission at the last hearing. The homes will be clustered and some land left open for agricultural use. The water main will be extended south from its present location, and storm drainage will be on - site. Street trees will be planted. The roads will be 30' wide with curbs) and sidewalks on one side. They will be city streets. A connection to Highland Terrace is shown, and additional screening from the Toutant land is shown. Mr. Trudell asked that the phasing schedule be changed to allow 40 units in the first phase. They want to build over 2 years instead of the 4 originally planned. Erosion control was discussed and Mr. Cobb noted that they would not strip all the land at one time. It was noted that the figure for intersection signallization contribution was in dispute and Ms. Bechtel said she would double check it. Mr. Jacob moved that the South Burlington Planning Commission approve the revised Final Plat application by Homer & Marie Dubois for a Planned Unit evelo went as depicted on a 23 page plan entitled "Led a Knoll Planned Unit Development" dated 11 16 83 and revised 12 30 83 and 1 _19 84, as prepared by Trudell Consulting Engineers with the following stipulations: 1. ' schedule: 5. PLANNING COMMISSION MAY 29, 1984 2. Lots will be cleared on a phased schedule and erosion control measures will be agreed upon by the City Planner. 3. That the concerns of the City Engineer memo dated 5/25/84) be addressed prior to permit. 4. That a performance bond of $30,000 for landscaping and an appropriate bond for streets, water and sewer, to be determined by the City Engineer and City Planner, be posted prior to permit. 5. That a recreation fee of 3200 per unit, totalling $11,400 be paid on a per unit phasing schedule. 6. That building setbacks will not be less than 30' in front, 10' on sides and 30' in the rear. 7. That Highland Terrace be extended to Dubois Drive after 50 units. 8. That project II (condominiums) be submitted with a connector street to the Goodrich property and that a second southerly access be provided.__ 9. That the open space which will be held in common by landowners after the condomin um units are built, and any residual development rights in the first phase of 57 lots and upon development of the remaining 53 acres, be deeded to the City. 10. That the applicant pay for signal improvements at Hinesburg Road_ and Kennedy Drive an amount to be determined by the City Planner. 11. That a stop sign be placed at Dubois Avenue for traffic exiting onto Hinesburg Road. 12. A bill of sale will be issued to the City for force main sewer and water line within the Hinesburg Road right-of-way rior to issu ce of buildi permits. 13. This approval will expire 3 years from this date. Mrs. Maher seconded the motion. Mr. Cobb noted that the applicant would just as soon deed the open land as well as the development rights to the city, in #9. Ma. Bechtel said the stipulation was intended to do two things. The open land would be held by the landowners, but the city wanted the development rights. Mr. Cobb said that when the back land was developed, they intended to deed the open land, the agricultural corridor and the wooded area to the Association. Until then, they want to keep the land other than the lots sold, in the Dubois name. It was noted that when the development was complete, the single-family lots would have an interest only in their own lots, while the condominium owners would have rights on the open space. Future development rights, such as those which would occur if the land were re -zoned, would be deeded to the city. The motion carried with all voting aye. Other business Ms. Bechtel said that she had been contacted by Queen City Park and Fire District #1 people. They want to have a public hearing sponsored by a city M E M O R A N D U M To: South Burlington Planning Commission From: Richard Ward, Zoning Administrative Officer Re: Next week's agenda items Date: 1/6/84 1) O'Brien -Business Park North, Lot #8 The report from North Country Planning (David Spitz) was reviewed by Dr. Oppenlander, a copy of his findings are enclosed. The report does not place much detail on the 2800 square foot office complex. The use will be general office area with real estate occupancy in part of the building. General office buildings generate 12.3 average weekday vehicle trip ends per 1000'g.s.f. of building area and 3.59 average weekday vehicle trip ends per employer. Office building - generated trips peak at the same time as adjacent street traffic (7 to 9 A.M. and 4 to 6 P.M.) The applicants attorney represented to the Zoning Board of Adjustment on October 17, 1983 a willingness to provide access to Kimball Avenue. I strongly suggest that a second access be considered by the Planning Commission. fi This office agrees with Attorney Schmucker that the use is grandfathered under the original P.C.D. development of Business Park Noth approval May 23, 1978. At that time traffic data submitted by Bruce Houghton projected around 20 average weekday vehicle trip ends for lot #8. Other than the Palmer office complex none of the other lots are developed however, I understand some have been sold. It has been suggested that if and when other lots are developed the Planning Commission could require access off Kimball Avenue to lot #8, I suggest by that time it will be to late. 2) Homer and Marie Dubois, Hinesburg Road Enclosed is Dr. Oppenlander's review of the traffic report submitted by Trudell Engineering. The major issue would be the installation of a three-phase signal control with left turn movement from Hinesburg Road on a separate phase. A section of the subdivision regulations provides that not more than 50 units be served by a cul-de-sac or a common single access to a major or secondary street. This proposal does not conform to that provision, 57 units are pro- posed. After discussing this with the City Engineer and the fact that this is a five (5) year project I suggest that the street layout is acceptable providing the following conditions are satisfied. 1) that phase IT of this project not be submitted until connector street are completed to the Goodrich property. 2) that a second access be provided to Van Sicklen Road. 3) that Highland Terrace be extended to Dubois Drive. The recreation fee should be paid according to the phasing schedule, the total fee being $11,400, prior to issuing any permits the fee would be $200 per unit. 'Phis E Memorandum Next week's agenda items 1/6/84 Page 2 will be a condition of approval at final plat. Performance bond for utilities and landscaping will also be included at final plat approval. 4 See memo from City Engineer. The sewer allocation for this project is 19,950 g.p.d., the Commission may want to phase this allocation based on the construction schedule, sewer usage would be figured at a rate of 350 g.p.d. per unit. 3) Bourdeau/Rye Sidewalk issue has been resolved. City Engineer agrees to location. 20' gravel access road to northerly property line is proposed. Major issue is location of buildings, this issue will be discussed at the next meeting. Fire Chief Goddette will attend. a 3. PLANNING COMMISSION JANUARY 10, 1984 interconnecting access for lot #,t7, as now or subsequently required by the South Burlington Planning Commission, for ultimate access to Kimball Avenue, to occur and coordinate with site -plan review for lot ft7. 3. That those concerns of the City Engineer -dealing, opening and driveway (memo 1 6 84) be included in the site plan and submitted to the City Engineer for approval prior to issuance of a permit. 4. That if the size of the bank facility changes it shall be subject to review by the Planning Commission. 5. There shall be signs which mark the internal traffic flow direction. 6. That the required number of handicapped parking spaces shall be designated on the plan of record. 7. This approval expires 6 months from this date. Mr. Belter seconded the motion and all voted aye. Conti ue--fAi-bl-ic hearing on preliminary plat application, 57 lot subdivision, (�Mr. Homer Dubois;, Hinesburg Road Mr. Ward noted that the regulations only allowed 50 units if there were just one access point. The applicants were told that requirement would restrict s development on the back portion of the land unless a second access were found. Mr. Trudell, representing the developer, said that adjoining property owner Art `i'outant had t d them about a drainage problem at the last meeting. He went and looked at it tNk next day and has taken care of it. The problem seems to be mainly on Mr. Tou ant's land and drainage will run the way it does now on the property in question. Mr. Ward noted that the City Manager had wanted to give a sewer allocation for the first 27 units of the project, feeling that by the time those units are complete, the sewer plant will have been upgraded. The Commission felt the allocation should be given for the entire 57 units, in case the upgrade does not occur. It was noted that they usually did give an allocation for the entire project. Mr. Ward noted that the level of service at the Kennedy -Hinesburg inter- section would not change as a result of this project and the Commission did not feel the developer should be required to do anything to that intersection. Lowering the speed limit in that area was discussed. Mr. Jacob suggested that that be investigated again. Mr. Jacob moved that the South Burlington Planning Commission approve the preliminary plat application of Homer and Marie Dubois for a 57 unit, single family development as depicted on a plat entitled "Ledge Knoll Subdivision" prepared by Trudell Consulting Engineers, Inc. dated November 16 1983 with revisions dated 12 30 83, subject to the following stipulations: 1. That the legal documents, including public street easeme:its,_utility easements,. easepientg servingadloininE: properties. etc, be submitted for approval by the City Attorney prior to final plat application. 2. That the sewer allocation be 19,950 gpd in accordance with the sewer policy developed by the Planning Commission. 4. PLANNING COMMISSION JANUARY 10, 1984 3. That the project is approved based on the following phasing schedule: Phase I - 15 lots (1984-85) Phase II - 12 lots (1985-86 )� Phase III - 18 lots (1986-87) Phase IV - 12 lots (1987-89) This schedule is not subject to change without Planning Commission approval. < 4. Those concerns of the City Engineer (memo 1/6/84) be addressed prior to submission of final plat application. 5. That screening along the Toutant property line be agreed upon by the City Planner and the developer and be included in the final plat application. 6. That Project II (condominium project) of this project be submitted with a connector street to the Goodrich property that a second southerly access be provided, and that Highland Terrace be extended. Mrs. Maier seconded the motion. Mr. Trudell asked about the second southerly access and was told that the project should eventually have access to Van Sicklen Road, or at least a second way to get in and out. This developer needs to leave a right of way open for another access point. Mr. Ward also felt Highland Terrace should be extended now. If there is a major accident on Hinesburg Road at the entrance to these lots, there would be no way to get in. The Commission agreed it should be extended now, and Mr. ward felt the extension could be to the same r standards the Terrace was now. It should be accessible year-round. The Commission said the Highland Terrace residents should be informed of the planned extension. Mr. Trudell mentioned a cedar hedge as the screening in �5, but Mr. Ward felt scotch pines might survive better and grow faster. This will be checked. The motion passed with all in favor. Continue public hearing on Bourdeau-Rye property, 28 unit planned unit develop- ment. Mr. Gerald Milot and Mr. Daniel J. O'Brien Mr. Ward said the only issue left was the building placement. At the last meeting the Commission had requested that the Fire Chief address them about his concerns. Mr. Milot said that the question of the design of the project had come up during sketch plan and preliminary plat hearings and the Commission had felt the design was adequate. The minutes of this meeting were read. At the final plat stage the Chief sent a letter saying he could not fight fires in the project. iir. Nilot said fir. Fitzpatrick had gone to speak with the Chief, proposing that streets near buildings be widened to 30' so two trucks could pass. An additional fire hydrant can also be added. The roads are now 24' wide. Mr. Goddette said his main concern was how to get around equipment that was already parked in order to fight fires and protect exposures. He noted that he had a truck that was only 8' wide, but had 12' stabilizers, so when that is on the scene, another truck cannot get around it. He said there were usually cars parked on the side of the road, and during the winter he lost space due to snow storage. Mrs. Maher felt the Chief was concerned with the safety of the people who would be living in these units and she felt he and the developer should meet again to see if they could come to a compromise.

BOX 2304 - SOUTH BURLINGTON, VERMONT 05401 Phone (802) 878-5977 December 16, 1983 Mr. Richard R. Ward Zoning Administrator City of South Burlington 575 Dorset St. South Burlington, Vermont 05401 Dear Mr. Ward: In compliance with your request, the report on Traffic for Homer and Marie DuBois, that was prepared by Trudell Consulting Engineers, Inc., has been reviewed in terms of the necessary content for a traffic impact study. In previous correspondence to you, the VAOT outline on the various topics that should be included in a traffic impact study was submitted as recommended guidelines to your office. The review of the above -mentioned impact study was conducted in accordance with the VAOT suggested format. Various comments have been noted in 'red' on the traffic portion of the report by Trudell Consulting Engineers, Inc. On page 4, uncertainty exists in regard to the use of the DHV values in 1988 for the proposed road intersection with Vermont Route 116. Based upon recent directional traffic counts at this location, the distributions are 75 and 25 percent northbound and southbound, respectively, in the morning peak hour. In the afternoon peak hour, the corresponding values are 33 and 67 percent. In addition, a projection factor of 1.09 for the period from 1983 to 1988 is low for Chittenden County. The value of 1.12 for forecasting might be more reasonable for this traffic location. Average peak hour volumes for the design year were used in the traffic study. However, the Vermont Agency of Transportation requires that design hour volumes be utilized in critical movement or capacity analyses. It is unclear in the traffic report as to how design hour volumes were prepared from VAOT machine counts. On page 21, minor errors were detected in the capacity calculations for the proposed access road and Vermont Route 116 during the morning peak hour. On pages 23 and 24, errors were noted in the critical movement analysis - planning determinations. Appropriate corrections have been noted in 'red' on the forms. In addition, it was noted that no changes are required at the intersection of Hinesburg Road and Kennedy Drive. However, the analyses were predicated on a change in number and configuration of traffic lanes. Pertinent comments have been noted in 'red' in the appropriate section of this analysis form. To enhance traffic flows and to reduce vehicular conflicts, three-phase signal control should be initiated with the left - A", turn movement from Hinesburg Road on a separate phase. The necessary I 2 geometric configuration is left -turn and through/right-turn lanes for all approaches at the intersection of Hinesburg Road and Kennedy Drive. On page 25, the evaluation of sight distances was performed for a crossing movement and not a turning movement. For the reported available sight distances, non -interfering approach operating speeds of 35 and 55 mph are available for northbound and southbound movements, respectively. Finally, no safety appraisals were included in this traffic impact study. This topic should be included to make the study complete. If you desire, a meeting can be scheduled with a representative from this engineering firm to discuss the above comments. Please advise if any additional assistance is required for this development application. Thank you. Very truly yours, Joseph C. Oppenlander, P.E. Vice -President JCO:njk TRUDELL CONSULTING ENGINEERS, Inc. December 13, 1983 Mr. Richard Ward Zoning Administrative Officer 575 Dorset St. South Burlington, Vermont 05401 RE: Ledge Knoll Dear Dick: In reply to your review comments of December 2, 1983, may I offer the following: 1. The water main location has been revised along Hinesburg Road to be 7 feet off r.o.w. line. 2. A culvert has been added at the entrance road. 3. Plans have been revised to include typical Town & Country street lamps at the major intersections, cul-de-sac and'on Knoll Circle. 4. Water services have been revised to be 90' off the main. 5. We have added catch basins at station 13+75 on Ledge Knoll and 17+00 on Dubois Drive to achieve spacing of 300'-400' between inlets. 6. Your comment on the cul-de-sac drainage is well taken, so we have revised grades here to pitch back to catch basins, and omit the curb outlet. 7. We have calculated available fire flows to the town house area at 1250 g.p.m. with an 8" line. This is the normal available flow without opening the reservoir valve on Dorset St. At this time we have no idea what type of building will be proposed for this future development. A typical, well thought out plan, of up to 5 units/building would require 1250 g.p.m. To be prudent in our planning, we have decided to increase the main to 10" diameter along Dubois Drive. This will provide 1500 g.p.m. under normal conditions and up to 2000 or more with the Dorset St. valve opened. BOX 308, WILLISTON, VERMONT 05495 (802) 879-6331 December 12, 1983 Page 2 8. Street plantings are all out of the right-of-way and on the individual lots. No plantings will be placed over the water mains. 9. Phasing is expected to follow a pattern: a. Phase I, Lots 1-7, 35-42 (15 lots) (1984-1985) b. Phase II, Lots 43, 57, 25-34 (12 lots) (1985-1986) C. Phase III, Lots 8-17, 44-51 (18 lots) (1986-1987) d. Phase IV, Lots 52-56, 18-24 (]_2 lots) (1987-1989) 10. The estimated costs of street plantings for this project is $24,120. 11. Prints have been supplied to the So. Burlington Water Department. We have received a favorable review from them. 12. We are looking forward to favorable review from Dr. Oppenlander. Hopefully concurrence with the Agency of Transportation position will be the outcome. Changes have been made to the plans where appropriate, and are included in our resubmittal.

Mr. Tyler Hart December 2, 1983 Page 2 12) Dr. Oppenlander will review your traffic data, his comments will be forwarded to you. If you have any questions don't hesitate to call me. Very truly, Richard ward, Zoning Administrative Officer 1U/mCg October 25, 1983 page 5 White Street for an addition of 500 square feet to an existi .k facility, as depicted on a plan entitled "White Street ice, the Merchants Bank," dated September 27, 1983 prepared Steve Moore. with the following stipulations: 1) That a landscaping bond in the amount of $750.00 be posted prior to issuance of a building permit. 2) This approval expires in 6 months. Mrs. Maher seconded, and the motion passed unanimously. Continue discussion and site construction of branch post Shelburne Road lan review of Mr. Gary Farrell, office, Sherwin Williams building Mr. Poger noted that letters had been received from Robert Mitchell and Donald Morley indicating that in their opinions the proposed facility would pose no problems with traffic in the area. Mr. Poger also noted that a letter from the City attorney, dated October 21, 1983, indicates that the Commission has the power to review traffic access even if it goes over boundary lines. Mr. Farrell said they have provided the information asked for and they don't foresee any problems since there is a light and since there is also a second access off Proctor Avenue. He added that they thought the service would be welcomed by people in the area who now have to travel to Burlington. Mr Ward said he had called Joe Openlander to do somell-,tudies in the area, but he was not available and said it would take 3 or 4 weeks. Mr. Jacob then moved that in view of letters received the Com- mission approve the applicatinn of Gary Farrell as far as the post office facility is concerned. Mr. Belter seconded and e motion passed -0 with Mr. Mona abstaining as he did not feel e traffic situation had been-fullV investigated despite the etters. Sketch plan review, two lot subdivision Trevithick property, 1 Spear Street Mr. Ward explained that the new lot will meet City standards. Mr. Poger asked what the access would be, and Mr. Trevithick said that one driveway would serve both lots. Mrs. Hurd asked whether the subdivision would render the back of the lot un- developable. Mr. Poger said it wouldn't as they could be given private access to Spear Street. Sketch Plan review of 57-lot subdivision, DuBois property Mr. Trudell explained that when they appeared before the joint Planning Commission/City Council meeting a number of recommen- dations had been made, and this revised plan is a result of that meeting. October 25, 1983 page 6 He advised that the new plan is more of a grid, eliminating.all of the cul de sacs except the one which had previously been a temporary cul de sac. Development will be done by individual builders. All lots have 100 ft. frontage and the minimum size is 19,000 sq. ft. There is as yet no plan as to what will happen to ownership of the agricultural corridor. Mr. Trudell asked whether they should continue Highland Terrace into the development. Mr. Poger suggested reserving it, but didn't think it would be needed. Mr. Trudell noted that the City Manager was looking for a sewer easement on a particular lot line and asked if they had flexibility to put it within that area. Mr. Ward said he would assume so. Mr. Mona noted that this development's sewer plans will dictate how Green Acres can be developed. It was noted that a master plan is being developed with Green Acres. Mr. Poger said that they can ask for an oversize line so others can hook onto it; the developer will be compensated for this. He noted there are large pieces of property across the road which might be developed and might want to hook on. Mr. Jacob said that the water main must be 12" with no payback allowed. Mr. Trudell said a small piece of land will be deeded with the pump station ad- jacent to Hardy's. Hardy will then have to provide a right-of- way to other properties. Mr Poger advised there will be a $200 recreation fee per unit. Mr. Trudell said they are proposing a 3-year phasing. Mr. Poger said that if the sewage bond issue passes, thay will probably be all right; if not, they may be asked to phase so that more people can get on the line. Mr. Trudell asked whether they must include a 50-ft buffer strip where they abut residential property. Mr Jacob said he didn't feel it was needed and Mr. Poger added that it was the expectation that if the usage of the other lot changes, they would have to provide the buffer. Mr. Ward stressed that the north property line must have a buffer. Mr Trudell said that in Mr. Szymanski's letter a left turn land on Hinesburg Rd. had been advised, but a current traffic evaluathn said it was not necessary. Mr Poger said it would be a tremendous benefit for safety and this should be discussed with Mr. Szymanski. Mr. Jacob said he hoped;the state would wake up and change the speed limit. Mr. Ward said this development might help in that regard. Mr. Trudell noted there will sidewalks on one side of the road. The Commission agreed that this plan looked much better than the previous one. Site plan review application, construction of an office/gara complex, 'Tilley Property, New Engiana Tele Nr. Don McKinnon, Real, Estate Manager for the Phone Company, introduced Dave Usher, Jim Burlage, and Peter Lukacic who explained the proposed project. The site includes 18 acres at the inter- section of Rts. 116 and 89. The building would be 2 stories, with 16,000 sq. ft. of'indoor parking for company vehicles. Mr. Usher said there are very significant changes in the telephone business. They currently have people and functions at 7 locations in the Burlington area, 5 of them leased. They are seeking an MEMORANDUM To: South Burlington Planning Commission From: William J. Szymanski, City Manager Re: Next week's agenda items Date: 10/21/83 7) Homer DuBois, Hinesburg Road 1. Sidewalks on one side of each street and street lighting should be in- cluded. 2. A 20 foot sewer easement should be reserved between lots 11 and 12 for adjacent properties. 3. A left turn passing lane should be included on Hinesburg Road. This and only other Hinesburg Road work will require State approval. 8) New England Telephone Building, Hinesburg Road 1. A by-pass lane to accommodate left turns into the facilities should be considered. However, all work on Hinesburg Road will require State review and approval. 2. Sewage contribution of 6,000 gallons per day will come out of the 50,000 gal per day increase in plant flow allowed in the City's amended pollution permit which is expected to be finalized on November 17, 1983 which is the end of the appeals period. 3. Plan title should read South Burlington not Burinigton. Memorandum Next week's agenda items October 21, 1983 Page 2 7) DuBois subdivision Trudell Consulting Engineers have requested another sketch plan review, in order to save time and money before they file a preliminary plat application. The proposed grid development has been reduced from the original 62 single- family lots to 57 lots. The revised plan reduces the proposed cul-de-sacs from six to one. The area of land involved with the grid development is approximately 37.5 acres of the entire parcel of 86 acres. The maximum density for the 37 acre parcel would be 75 units. I'm assuming.that eventually the 110 multi -family units will be submitted for approval. The maximum overall density permitted is 172 units. Sewer and water must be resolved,the sizing of the pipes should be discussed. Any oversizing should be reviewed by the City Council and Water Department. The sewer allocation for this portion of the project would be 14,250 g.p.d. Some discussion regarding phasing would be appropriate, in light of the fact that presently approval projects have an allocation 10.750 g.p.d. 8) New England Telephone, Tilley land, Hinesburg Road Parcel of land in question is southerly of Interstate 89, bounded by the inter- state and lands of Mitel and Wright. The parcel contains approximately 18 acres and is zoned IAg District. The proposed building contains 55,OOO square feet of office area with a garage area of 16,000 square feet. Average daily traffic to this location will be 300 vehicles, employees are estimated at 295. Peak hours are 7:45 A.M./8:15 A.M. representing 72% of total or 216 trips and 5:00 P.M./5:30 P.M. representing 60% of total or 180 trips. Additional in- formation is expected by Joe Openlander. Only zoning issue is landscaping, I expect a revised plan. All other requirements are conforming. Additional comments are due from Fire Chief and City Engineer. State Highway Department permit will be required. Comments regarding stacking and turn lanes should be directed to the State Highway Department. No formal action should be taken at this meeting. October 12, 1983 Mr. Honer DuBois 1405 Hinesburg 1Zoad South Burlington, Vermont 05401 Re. Stripping topsoil Dear Horner; The Planning CoitaTtission has expressed sow concern that you are stripping top- soil from the are* of your proposed subdivision without first obtaining the necessary State and local permit,,-- This office feels that your grandfathere6 permit for stripping does not include this area. In light of the fact that Dick Trudell has made application for preliminary approval of your proposed 57 lot subdivision, I suggest that you discontinue stripping. If you have any questions please don't hesitate to call me. Very truly, Richard ward, Zoning Administrative Officer RW/mca MEMORANDUM To: South Burlington City Council From: Richard Ward, Zoning Administrative Officer Re: Topsoil stripping on Dubois farm Date: 8/9/83 Be advised that the topsoil removal at the Dubois farm has been occurring for many years. Permits were issued by the State Agency, local ordinances at the time were not in effect. Most of the land stripped has been restored with hay crops planted and harvested. The area is still considered as a prime agricultural area. The land was farmed until a few years ago when the main barn was destroyed by fire. Page 4 ) ) David Spitz has responded to this study recommending a seasonal adjustment and a slightly smaller building size. He also calls attention to the imprecise characteristics of these figures and recommends the Commission not rely on them as absolutes. (see letter 4/9/84) The chart below summarizes the 4 sources of traffic data and corresponding maximum building size. It should be noted that each source, with the exception of the Court, used a size of 37,954 square feet, while the actual lot is 38,225 square feet. The court however, seems to have made mathematical errors in cal- culating ..size. The fourth column reflects the maximum building size if the accurate lot size is used. Maximum Recalculated Source Trips/GFA Bldg. Size Using Actual Lot Size ITE 25/4800 4554 sq. ft. 4587 sq. ft. or 5.21/1000 Court 22/4800 5217 sq. f t. or 4.58/1000 (court calculated 5160) Fitzpatrick- 17/4800 6682 sq. ft. 6730 sq. ft. Llewellyn or 3.55/1000 D. Spitz (seasonal adjustment) 6309 sq. ft. Given the variation in these estimates, and their imprecise characteristics, I recommend not relying on anyone source as an absolute. I do not believe a red- uction in building size by 380 square feet or by 2000 square feet will produce a significant reduction in traffic flow. I do not believe there are grounds to deny this application, however, the Commission may wish to mediate between the residents and the applicant to best meet the residents concerns. I recommend the commission approve the Site Plan as a reasonable use of the property and as meeting all local requirements. I have discussed this application with the City Attorney and he believes this should be viewed as a new application putting aside any issues raised by the courts. rr 4. Homer and Marie, Dubois, Ledge Knoll PUD The applicant has proposed a revised construction phasing schedule for you approval as follows: Original Approval Revised Phase I (1984-85) 15 lots 40 lots Phase II (1985-86) 12 lots 17 lots Phase III (1986-87) 18 lots Phase IV (1987-88) 12 lots TOTAL 57 lots 57 lots Pdyu J The revision is requested due to high upfront costs for sewer and water, and the considerable amount of interest already expressed in these lots. The Commission should discuss whether this schedule is advisable without significant erosion control measures. It is policy to charge applicants for a portion of the signalization improvements at Hinesburg Road/Kennedy Drive. These will cost approximately $20,000. The cost is to be shared among estimated major new developments in the area over a 5 year period (387 trip ends per peak hour). This development is estimated to generate 43 peak hour trip ends through the intersection, (57 units x 75% to the intersection x 1 per unit). Therefore the required amount for this applicant will be 43 ; 387 x $20,000 = $2200. to be placed in escrow and to be applied only to the Kennedy Drive/Hinesburg Road intersection signal improvements. The City Engineer has expressed concerns that should be stipulated. (see memo 5/25/84). All other issues of the Planning Commission and the City Council have -been re- solved and/or are stipulted in the approval motion.

PLANNING COMMISSION DECEMBER 13, 1983 Public hearing, preliminary plat application, 57 lot subdivision of Mr. Homer Dubois, Hinesburg Road Mr. Trudell said the existing 12" main at the edge of the Mitel property would be extended to provide water for this development off Hinesburg Road. Sewer lines will be put in to the pump station on the Mitel site. The portion of the site nearest Hinesburg Road will be the housing development under discussion now. Behind that is a wooded area, which is lower and wet. Behind that area is land left for an agricultural area and a corridor to tie various areas together to facilitate agricultural use. The plan also shows an area being considered for future multi -family use. There are no plans for that area right now. Mr. Trudell said one cul-de-sac had been left in the road layout - the access for the future multi -family area will be through that point. There will be a pump station on a small lot near the cul-de-sac. Some of the lots will have gravity flow north to south, where the pump station will pick up the flow and pump it back south to north toward the Mitel pump station. Water lines inside the development will be 10", to serve any future development of the area. Drainage will go toward the low area behind the housing lots. Mr. Arthur Toutant said he lived on Hinesburg Road adjacent to this area. He owns 7 112 acres and runs a bird farm there. He said that there is almost no percolation in the area, and that for 3 to 4 weeks in the spring the runoff is very heavy. Mr. Trudell said that they would take another look at that. Mr. Toutant said he also wanted to go on record as stating that he had a lot of birds and that at certain times of the year they were very noisy. His 30-40 peacocks make a lot of noise early in the morning during mating season. He said he was planning to raise 5,000 turkeys as well, and that having so many birds produces a lot of manure. It was noted that the agricultural use was grandfathered, but if Mr. Toutant sells any of his land, he will be in violation of the zoning requiring a minimum acreage for this type of use. Mr. Trudell said all the engineering items had been cleared up, but that they would update the plans and bring them back in. It was noted that it might be in the developer's best interests to create a buffer between the house lots and Mr. Toutant's farm. Mrs. Maher moved to continue consideration of the preliminary plat application of Mr. Homer Dubois to the next regularly scheduled meeting, on December 27, 1983 at 7:30 pm at City Hall. Mr. Mona seconded the motion and it passed with all voting aye. Consider request of Attorney Peter Sidel to close off the access road between Indian Creek and Ridgewood Estates Mr. Poger noted that when Ridgewood was approved originally, the Commission had wanted a road to run from Dorset St. to Swift St. When Ridgewood was split into two developments, the Commission was asked to have the access road closed, but they refused. Now they are being asked again. Mr. Sidel said that in the early 1970's the Commission minutes note a concern about a through road in this development. Mr. Poger said it was designed with curves to slow traffic and make it safer. Mr. Sidel said the Indian Creek homeowners had met recently and had agreed with the Ridgewood owners that they would like the access between the two closed. This would promote harmony between the two areas. The residents feel that there is quite a bit of traffic during the day over the road and that the speed of cars has increased, perhaps because there are no homes near a portion of the road. Children are also using this open area for a play area.

The minimum live load capacity is 150 pounds per square foot and the factory finish is a prime coat of led oxide paint. TYPE T — Designed to provide access through a finished floor area, the Type T door is virtually hidden after installation. Specially designed concealed hinges allow consistently close tolerance on all sides between the aluminum plate door leaf and the extruded alumi- num frame. Built-in torsion bars afford ease of operation. The door locks open at 90 degrees; a vinyl grip handle is provided for releas•, ing the hold -open lock and closing the cover with one hand. A neo- prene cushion built into the frame prevents metal -to -metal contact. Doors are built for a minimum live load of 150 pounds per square foot. Molding strips are applied to leaf and frame to receive either t/a" or e;" floor covering. Except for the molding and the ferrule around the lock aperture, the door is entirely concealed. TYPE TO — Similar in design to the Type T above, except double - leaf design for larger openings. TYPE K — Similar in design to the Type T above, except that the leaf is 1/4" aluminum diamond pattern plate. It is ideal for floor ,Irt',rs not covered by composition flooring.

DATE: NOVEMBER 15, 1983 DESCRIPTION The DuBois subdivision consists of about 60 single family .lots served by a paved public street. The lots average % - i acre in size. The site slopes down toward the east averaging 5-8% slopes. Soils on the site are clay. Surface runoff drains to a low wet area on the site, and then northerly. BASIS FOR DESIGN The proposed drainage system consists of drop inlets and subsurface conduits in the roadway. Runoff will be conveyed to the existing wet area. All pipes will be sized to carry runoff from the 10 yr. 24 hr. rainfall. The method of analysis is the S.C.S. Tabular Hydrograph method for Type II storms as outlined in "A Guide to Hydrologic Analysis Using S.C.S. Methods", by Richard H. McCuen. J 1 ) TYPE II STORM 1.0 YR RETURN 24 HR P = 3.6" AREA AVG.

Prepared By: TRUDELL CONSULTING ENGINEERS, INC. Williston, Vermont Date: October 10, 1983 1 Z. Proposed Development The project consists of a residential subdivision located easterly of Route 116 in South Burlington, Vermont. Access to the subdivision will be onto Route 116 about 2000 ft. north of Van Sicklen Road. The access road will be paved with curbs, and will be offered to the City upon completion. Phase I of the project will create 60 single family lots, and is expected to take 5 years to completion. This report addresses the impact of the project through the next 5 years to 1988. /J Z y / r S BURLINGTON p ►OrwT - /✓ POP. 35,531 qr p NO ' CENMAL YCANON" � �M0of LO80c � IM7°O P BtOh 127 yP F4P 7 o 0.-�.- aP`" \ fRgr _ .4 \\ _______�_, J\� Ln 5P �Sq SA 07 2 &� ..... o SA FAP Sa n 1� FA 03 2 � U (J to N eURL1A \\ 7 S4 tyt��.fi„ V MUDOD q0 'r v � \ � � �'( , , ,, F4F 0SF►'fC 1 Ln vent \ N SOUTH BURLINGT N - ,'2 AIR u`. \ r l e S-2 SECTIONS EST POP 441IS � � a 61 o e�ti a ISLAND ":`a'a. ) I 3 `.: FA1' o! t mo0. d f✓j /l ^ o ^ POCK L DYMDLt �- _ M..nw✓' "iA. e�0 • �+ :i{'.

Destination of traffic is determined by available employment opportunities and distance from the site. These two factors are given equal weight. Peak hour trips are then determined for each destination, and each intersection under consideration. The proposed access intersection, and the Route 116-Kennedy Drive intersections are selected for a critical movement analysis. The estimated traffic turning movements are tabulated on exhibits #1, 2, 3, and 4.

Adjust the frame to grade with a minimum of 2 courses of brick set in mortar and mortar the frame to the top of the eccentric cone. H. Service connections from the main line to the property line shall be 6 inch polyvinyl chloride pipe. Cap the ends tightly and mark the end location with a 2 x 4. Run the 2 x 4 from the cap to 1 foot above the surface and mark with the letter "S" (spray paint). SANITARY SEWER 02722- 11 LEDGE KNOLL \ \ 3.07 TESTING SEWERS ) ' A. Test the gravity sewer by a pressurized air test between consecutive manholes. Plug the two ends of the pipe and connect the air control equipment to the tapped end. B. Supply air slowly to the pipe until reaching a constant pressure of 3.5 psi, throttle the air supply so that the pressure remains above 3.0 psi for at least 5 minutes to allow temperture stabilization in the pipe. C. After stabiliztion, adjust pressure to 3.5 psi and shut off air supply. When the pressure reaches 3.0 psi start the stop watch and record the time it takes to reach 2.5 psi. The time must be at least: 4 inch 2 minutes 32 seconds 6 inch 3 minutes 50 seconds 8 inch 5 minutes 6 seconds 10 inch 6 minutes 22 seconds 12 inch 7 minutes 39 seconds D. If laterals are included in the testing, the average of the pipes (using diameter and length) will be calculated and multiplied by 38.2 seconds to obtain the required time. E. If there is ground water above the sewer line the air test pressure will be increased by 0.5 psi for each foot of water above the invert of the pipe. 3.08 TESTING MANHOLES A. Each manhole shall be tested by means of a water test. If a water test was used on the sewer line and the manhole was tested with the sewer, and the line passed, the Engineer may not require an independent manhole test. In any case, there shall be no visible leakage into the base or walls of a completed manhole. B. After the manhole has been assembled in place, all lifting holes and those exterior joints within 6 feet of the ground surface shall be filled and pointed with an approved non -shrinking mortar. The test shall be made prior to placing the shelf and invert. If the groundwater table has been allowed to rise*above the bottom of the manhole, the Engineer may direct it to be lowered for the duration of the test. All pipes and other openings into the manhole shall be suitably plugged and the plugs braced to prevent blowout. SANITARY SEWER 02722- 12 LEDGE KNOLL \ \ C. The manhole shall then be filled with water to the top of the cone section. A period of one hour will be permitted, to allow for absorption. At the end of this period, the manhole shall be refilled to the top of the cone, if necessary, and the measuring time of at least 6 hours begun. At the end of the test period, the the manhole shall be refilled to the top of the cone measuring the volume of water added. This amount shall be converted to a 24 hour rate and the leakage determined on the basis of depth. The leakage for each manhole shall not exceed one gallon per vertical foot for a 24 hour period. Repairs by approved methods may be made, as directed by the Engineer, to bring the leakage within allowable rate of one gallon per foot per day. It shall be the Contractor's responsibility to uncover the manhole, as necessary, and to disassemble, reconstruct or replace it as directed by the Engineer. The manhole shall then be retested and, if satisfactory, interior joints shall be filled and pointed. D. If the Contractor elects to backfill prior to testing, for any reason, it shall be at his own risk and it shall be incumbent upon the Contractor to determine the reason for any failure of the test. No adjustment in the leakage allowance will be made for unknown causes such as leakage of plugs, absorption, etc. i.e., it will be assumed that all loss of water during the test is a result of leaks through the joints or through the concrete. Furthermore, the contractor shall take any steps necessary to assure the Engineer that the water table is below the bottom of the manhole throughout the test. E. If the groundwater table is above the highest joint in the manhole, and if there is no leakage into the manhole as determined by the Engineer, such a test can be used to evaluate the water tightness of the manhole. However, if the Engineer is not satisfied, the Contractor shall lower the water table and carry out the test as described hereinbefore.

Pipe installation by jacking or boring shall be used only upon approval of the Engineer. 02725- 9 FORCE MAIN LEDGE KNOLL � . � _ B. GENERAL 1. Jacking - Installation shall consist of pushing the pipe into the soil and excavating and removing the soil through the pipe. Contractor shall not excavate soil ahead of the pipe, to prevent unsupported excavation ahead of the pipe. The use of water or other liquids to facilitate casing emplacement and spoil removal is prohibited, 2. Boring - Installation consists of pushing the pipe into the soil with a boring auger rotating within the pipe to remove the spoil. When augers, or similar devices are used for pipe emplacement, the front of the pipe shall be provided with mechanical arrangements or devices that shall positively prevent tho auger and cutting head from leading the pipe by more than the length of the cutting head, to prevent unsupported excavation ahead of the pipe. The auger and cutting head arrangement shall be removable from within the pipe in the event an obstruction is encountered. The over -cut by the cutting head shall not exceed the outside diamter of the pipe by more than on -half inch. The face of the cutting head shall be arranged to provide reasonable obsruction to the free flow of soft or poor material. The use of water or other liquids to facilitate casing emplacement and spoil removal is prohibited. B. If an obstruction is encountered during installation to stop the forward action of the pipe, and it becomes evident that it is impossible to advance the pipe, operations will cease and the remainder of the pipe shall be installed by open cut (3.04). C. Bored or jacked installations shall have a bored hole essentially the same as the outside diameter of the pipe plus the thickness of the protective coating. If voids should develop or if the bored hole diameter is greater than the outside diameter of the pipe (plus coating) by more than approximately 1 inch, grouting or other methods approved by the Engineer shall be employed to fill such voids. D. The materials to be used and the method of injection shall be prepared by a Registered Professional Soils Engineer, or by an experienced and qualified company specializing in this work and submitted for approval to FORCE MAIN 02725- 10 LEDGE KNOLL the Engineer before the -start of work.

As presently designed, it would be my opinion that the project complies with Criterion 9(b). In fact, I would like to commend you on this site plan as a good example of how residential and agricultural needs can be mutually satisfied within a project. Furthermore, the agricultural corridors which you have established on this land present the City of Burlington with an opportunity to orient open space associated with future projects on adjoining lands towards these corridors to, in effect, produce an "agricultural/open space district" within and associated with residential and industrial develop- ments. I hope that if you are the engineer for any of these future projects, you will encourage this concept. Thank you for supplying me with this information and for allowing me to be able to conu»ent on this project so early in the planning stages. Sincerely, Robert C.

CITY COUNCIL FEBRUARY 22, 1984 The South Burlington City Council held a Regular Meeting on Wednesday, February 22, 1984, at 7:30 pm, in the Conference Room, City Hall, 575 Dorset Street. Members Present Paul Farrar, Acting Chairman; Leona Lansing, Michael Flaherty, William Peters Member Absent Hugh Marvin, Chairman Others Present William Szymanski, City Manager; D,vid Minnich, Assistant City Manager; Robert Chittenden, State Representative; Bruce O'Neill, Recreation Director; William Schuele, Natural REsources Committee; Ethel Schuele, Fine Arts Committee; Ruth Poger, The Other Paper; Gayle Blood, Mark Abrams, Elizabeth Edwards, Edith Hendley, Nan Frymoyer, Bradford Shaw, Bob Furlong, Lowell Krassner Comments and questions from public not related to items on Agenda There was no discussion in this area. PUBLIC HEARING: Application of Homer & Marie Dubois fora planned unit development located off the east side of Hi_n_e_s_7u_rg Road approximately mile north of Van Sic en Road Mr. Farrar explained that this procedure is required because development of the Southeast Quadrant is allowed at a density of 2 units per acre only if the developer can prove that such development will not have an undue impact on the community. Mr. Trudell, the developer of the parcel, then updated the development plans. He advised that the three parties involved had gone to a hearing regarding 119B,11 and had received the Findings of Fact from that hearing (attached). The findings indicated that development was to be un(1ertaken using agri- cultural corridor concepts. The plan now calls for a 57-lot subdivision on almost 35 acres. The new layoud has no cul de sacs as the first layout had had, and the road is now straighter. There will be a 12" water service which will continue into the project. Sewer service is available at the Mitel pumping station, and Mr. Dubois is now negotiating with Green Acres as to where the sewer easement will be. A right-of-way will connect with the Green Acres parcel. The Planning Commission had asked that the road connect into Highland Terrace, and this has been added to the plans. The project has been submitted to the Agency of Transportation, and a go-ahead has been received pending Act 25C approval. Additional screening has been provided on the border of Mr Toutant's property. CITY COUNCIL February 22, 1984 page 2 Mr. Peters raised the question of development of adjoining land. Mr. Trudell said that Mr. Goodrich things his lot will be de- veloped as industrial, and a buffer strip is planned between the two properties. Mr. Farrar asked whether the approval being sought is for the entire concept or just this first phase. Mr. Trudell said only this phase is being considered now. The remaining parcel will still meet the criteria for PUD development. At present, the second phase development would be condominiums. Mark Abrams of Highland Terrace questioned the extension of Highland Terrace. He read a lead a letter into the record (attached) citing increased traffic and air pollution and reduced safety, especially for the young children on Highland Terrace. It also noted that the extension would give access to only 4 homes, which is a marginal benefit. The extension was requested based on the arising of simultaneous emergencies, and the residents feel this is not likely, especially in view of the dangerous intersection which is a more immediate danger. The asked that if such a road extension is passed that the road be a 12 foot gravel road with chains at each end and a sign indicating for "Emergencies Only". Edith Hendley of Highland Terrace cited the dangerous access that now exists and said that 57 more families competing will make it much worse. Mr Ward noted that the approval included the provision that when the DuBois property was developed, the extension of Highland Terrace would be built. The present development cannot be ap- proved without a second access road. He added that with the extension, there will be better site visibility. Mr. Farrar suggested that in the future, it might be to everybody's benefit if the second access could be put to the north on Green Acres, and it might be better to close the Highland Terrace access and use only the new ones. Ms. Blood wanted to know the type and value of the homes to be built. Mr. Trudell said they do not yet know whether the lots will be sold individually, in groups or to one developer, and the style will depend upon the buyer(s). He felt that the homes would be a minimum of $75,000. Regarding power lines, these will be underground with the exception of a pole and the area near the pipes where vehicle traffic would cause damage. He added that if they can find someone who knows where the pipes are, they would sleeve them. Mr. Furlong questioned why there is to be screening behind the Toutant property and nowhere else. Mr. Trudell noted that Mr. Toutant is planning to expand his bird farm operation. Mr. Schuele questined the selling off of individual lots noting that once you do that, your PUD is not "planned" at all. Mr. Farrar said that approval is only for specific size lots, street locations, etc, not for individual homes. Ying Nu asked how effective the access route to Highland Terrace will be in the early phase of the development. Mr. Farrar said he personally viewed the access to the north as the true secondary access. CITY COUNCIL February 22, 1984 Page 3 Mr. Shaw questioned the sewer capacity noting they are nearing capacity with half of the development. Mr. Farrar advised there will be a bond issue to upgrade the capacity and quality of the Airport Parkway plant. Mr. Furlong asked whether the Mitel allotment has been left in tact although it is not in use. Mr. Szymanski said the Mitel allotment is reserved- He also advised that an easement has been left between the Furlong and Toutant lands so both could hook onto the sewer. Mr. Krassner asked whether the people who buy property in the development will pay for the sewer expansion or if the rest of the citizens will be subsidizing this. Mr. Farrar said the procedure currently is that all citizens pay by means of the bond issue. Mr. Farrar then asked if they had a statement from the School Department on the impact on schools. Mr. Trudell said in a letter of November 14,-1983, Mr. Tuttle indicated no unreasonable burden would be placed on the schools. They also have approval of the Fire Chief. Mr. Farrar then asked about plan for common lands. Mr. Trudell said they would remain in Mr. Dubois name until he develops Phase II. No proposal has yet been made. Mrs. Schuele asked about minimum yardage between homes. Mr. Trudell said there will be 15-20 foot side ye and that other R-2 setbacks would apply (30 foot rear and front). Mr. Ward said he would prepare a proposed motion addressing all of the concerns raised and would have this for the next meeting. Mr..'Trudell advised that the ruling is that the City must be a co -applicant for Act 250 along with Mitel and Green Acres in regard to the sewer which goes through their land. Mr. Flaherty then moved that the hearing be continued until the meeting arc wi h the understanding that there will be a written proposed motion from the Acting City Planner Tor the Council to act upon. Ms. Lansing seconded with unanimous consent. Review of 1984-1985 Budget Mr. O'Neill explained the capital expenditures the -Recreation Department was requesting. These include $5,000 for renovation of the high school tennis courts which need a major overhaul, $2,600 for insulation of the O'Brien Center, and additional funds for painting and repair of the O'Brien building. Mr. Farrar asked that the City Manager report on the potential energy savings from the building insulation at the next meeting. Mr. O'Neill noted that there is a small fee for private use of the building and that there have been a few small donations. There is very little change in the Fine irts budget, mainly an increase in salary for returning summer employees. Mr. Farrar raised the question of overestimating summer help salaries.

June 8, 1984 Mr. Ernest P. Christsianson District Administrator Agency of Environmental Conservation 111 West Street Essex Jct., Vermont 05452 RE: Homer & Marie Dubois Dear Mr. Christianson: Reference is made to your letter of June 5, 1984. Please be advised that the City of South Burlington has approved all 57 lots and allocated sewage flows for all 57 lots. The difference between the estimated quantity in our design brief (27,514 gpd) and the City's allocation (19,950) is as follows: Trudell City 57 Homes @ 450 gpd = 25650 Infiltration estimate = 1864 .8.1'd 27514 gpd 57 Homes @ .350 gpd = 19950 gpd 19950 gpd I have discussed this difference with the City Planner, Jane Bechtel, anticipating that this question would arise. The City's experience has been that single family homes generate less than 350 gpd at the treatment plant and that their allocation is based on their actual experience and is therefore proper, as well as conservative. It is our understanding that the City's figures have been consistently accepted in the past, and we therefore see no reason why they should not be in this case.

December 13, 1983 Mr. Richard Ward Zoning Administrative Officer 575 Dorset St. South Burlington, Vermont 05401 RE: Ledge Knoll Dear Dick: In reply to your review comments of December 2, 1983, may I offer the following: 1. The water main location has been revised along Hinesburg Road to be 7 feet off r.o.w. line. 2. A culvert has been added at the entrance road. 3. Plans have been revised to include typical Town & Country street lamps at the major intersections, cul-de-sac and on Knoll Circle. 4. Water services have been revised to be 90' off the main. 5. We have added catch basins at station 13+75 on Ledge Knoll and 17+00 on Dubois Drive to achieve spacing of 300'-400' between inlets. 6. Your comment on the cul-de-sac drainage is well taken, so we have revised grades here to pitch back to catch basins, and omit the curb outlet. 7. We have calculated available fire flows to the town house area at 1250 g.p.m. with an 8" line. This is the normal available flow without opening the reservoir valve on Dorset St. At this time we have no idea what type of building will be proposed for this future development. A typical, well thought out plan, of up to 5 units/building would require 1250 g.p.m. To be prudent in our planning, we have decided to increase the main to 10" diameter along Dubois Drive. This will provide 1500 g.p.m. under normal conditions and up to 2000 or more with the Dorset St. valve opened. BOX 308, WILLISTON, VERMONT 05495 (802) 879-6331 I December 12, 1983 Page 2 8. Street plantings are all out of the right-of-way and on the individual lots. No plantings will be placed over the water mains. 9. Phasing is expected to follow a pattern: a. Phase I, Lots 1-7, 35-42 (15 lots) (1984-1985) b. Phase II, Lots 43, 57, 25-34 (12 lots) (1985-1986) c. Phase III, Lots 8-17, 44-51 (18 lots) (1986-1987) d. Phase IV, Lots 52-56, 18-24 (12 lots) (1987-1989) 10. The estimated costs of street.plantings for this project is $24,120. 11. Prints have been supplied to the So. Burlington Water Department. We have received a favorable review from them. 12. We are looking forward to favorable review from Dr. Oppenlander. Hopefully concurrence with the Agency of Transportation position will. be the outcome. Changes have been made to the plans where appropriate, and are included in our resubmittal.

As presently designed, it would be my opinion that the project complies with Criterion 9(b). In fact, I would like to commend you on this site plan as a good example of how residential and agricultural needs can be mutually satisfied within a project. Furthermore, the agricultural corridors which you have established on this land present the City of Burlington with an opportunity to orient open space associated with future projects on adjoining lands towards these corridors to, in effect, produce an "agricultural/open space district" within and associated with residential and industrial develop- ments. I hope that if you are the engineer for any of these future projects, you will encourage this concept. Thank you for supplying me with this information and for allowing me to be able to comment on this project so early in the planning stages. Sincerely, Robert C.

Proposed Ihibois Develolnnent Dear Mr. Hart: The application for a permit to construct a new access at the location indicated, as submitted by you for Homer and Marie Dubois, has been received, along with your letter. Regarding the proposed intersection geometry, it should be in accord with detail C of standard B-71., rather than with detail G. Also, note the profile requirements on the same standard sheet. The traffic generated by this proposed development will not adversely impact traffic flows on Vt, Route 116. The intersection of the proposed access drive and Vt. Route 116 will operate at level of service A in 1988 with the proposed development. The intersection of Vt. Route 116 and Kennedy Drive will operate at level of service A for anticipated design hour volumes during the 1988 ANI peak travel period and will operate at level of service C during the 1988 PM peak travel period. Traffic control signals and separate turn lanes will not be required at the intersection of Vt. Route 1.16 and the proposed access location.. However, the exiting traffic from the proposed development should be controlled by stop signs. It appears that the sight distances will be adequate if -the brush along the easterly side of Vt. 116, each sicle of the pro- posed access, is cleared. For the desired line of sight, see note u8 of standard sheet B-71, co1y enclosed. y Mr. Tyler Hart Proposed Dubois Development Page 2 November 18, 1983 I note that in your letter of October 26, 1983 you indicated that you submitted a copy of the Dubois application to the City of South Burlington for review, We would like a copy of their comments. Before any work is done on the proposed access within the highway right-of-way, we must receive and approve detailed plans of the access. In addition, we must receive a copy of the con- ditions, imposed by the land use permit, that pertain to access. erely, . � 0 J.es H. Hoag Utilities Engineer Enc.

CHIEF 863-6455 Plans have been reviewed by the fire department on the Ledge Knoll development that Mr. Dubois is looking for approval off Hinesburg Road. At this time I do not see a problem with the lay out for the single lots, But can see one in thefurture when he would want to build the condos. The problem is that the 8" water main from Hinesburg Road to the circle which would be extended at a later date would not be large enough to supply the amount needed for the size on the condos units. I have talked to Mr. King from Trudell Engineering office and he see"s the problem and feels the same as I do that provisions should be made at this time so that the water main is large enough so not to have a problem when it comes time to build condos. I think if the planning commission has the water main corrected to take care of conds to be built at a later date we will know are needs have been taken care of.

Land Use Code 210 as follows: Peak Hour ain enter ,97 trips/dwelling unit exit to it pm enter .04 if of exit .36 itit Turning movements are estimated by determining the destination of traffic and probability of using available routes from the site. Destination of traffic is determined by available employment opportunities and distance from the site. These two factors are given equal weight. Peak hour trips are then determined for each destination, and each intersection under consideration. The proposed access intersection, and the Route 11.6-Kennedy Drive intersections are selected for a critical movement analysis. The estimated traffic turning movements are tabulated on exhibits #1, 2, 3, and 4.

INTRODUCTION On April 18, 1984, an application for an Act 250 permit amendment was filed by Homer and Marie DuBois of 1405 Hinesburg Road, South Burlington, Vermont for the subdivision of an 86 acre parcel into 57 residential lots and one 53 acre lot and the construction of 4,000 feet of roadway and utilities located off of Hinesburg Road. The sewer line servicing this project will be located on lands owned by co - applicants, Mitel, Inc.; Susan and Linus Wiles; and Richard and Ann Painter and will be conveyed to the City of South Burlington. The tract of land subject to Partial Findings of Fact #4CO530 dated November 12, 1982 and issued to Green Acres, c/o Ralph Goodrich, Homer and Jackie DuBois and William and Sara Mikell consists of 328 acres. The tract of land owned by Homer and Marie (Jackie) DuBois, and subject to this application, consists of 86 acres with 33 acres involved in the project area. The applicants' legal interest is ownership in fee simple. Under Act 250, projects are reviewed based on the 10 criteria of 10 V.S.A., Sec. 6086 (a) 1-10. Before granting a permit, the Board or District Commission must find that the project #4CO530-1 Findings of Fact Page 2 complies with these criteria and is not detrimental to the public health, safety or general welfare. This application is subject to Partial Findings of Fact #4CO530 under subsection 9(B). Decisions must be stated in the form of findings of fact and conclusions of law. The facts we have relied upon are contained in the documents on file identified as Exhibits #1 through #70, and the evidence received at a hearing held on May 25, 1984. At the end of the final hearing, the proceeding was recessed pending submission of additional information. The hearing was finally adjourned on June 27, 1984 upon receipt of all of this additional information. Parties to this application who attended the hearing are: The Applicants by Homer and Marie DuBois, Richard Trudell and Carl Cobb; The Agency of Environmental Conservation by Dana Cole - Levesque, Land Use Administrator and the Vermont Department of Agriculture by Amy Justes. The Entry of Appearance and Pre -Hearing Comments filed by Dana Cole -Levesque, of the Agency of Environmental Conservation were entered into the record. II. FINDINGS OF FACT In making the following findings, we have summarized the statutory language of the 10 criteria of 10 V.S.A., Sec. 6086 (a) : SECTION 6086(a) (1) WATER AND AIR POLLUTION: The Commission finds that this subdivision will not result in undue air or water pollution. This finding depends on and is supported by the findings noted under the subsections of this criterion. SECTION 6086(a) (1) AIR POLLUTION: The Commission finds that this subdivision will not result in undue air pollution. This finding depends on and is supported by the following: #4CO530-1 Findings of Fact Page 3 1. The individual homes will be heated with electric, gas, fossil fuel or wood fired heating systems, which will not cause undue air pollution (Exhibit #9). 2. Open burning is prohibited by the Protective Covenants, Item 8 (Exhibit #61). 3. The project is expected to generate 570 vehicle trips per day which will not result in undue air pollution (Exhibit #9 and testimony of applicant). SECTION 6086(a) (1) (A) HEADWATERS: The Commission finds that this subdivision is not in a headwaters area as defined by this section because stepp slopes and shallow soils exist only on a limited area of the site, the drainage area is 119 acres, the elevation of the site is 338 to 420', this area is not a watershed of a public water supply, and because the site does not supply significant recharge to aquifiers (Exhibit #9). SECTION 6086(a) (1) (B) WASTE DISPOSAL: The Commission finds that this subdivision will meet applicable Division of Protection Regulations and will not result in the injection of waste materials or harmful or toxic substances into groundwater or wells. This finding depends on and is supported by the following: 4. The estimated 19,950 gallons per day of sanitary wastes will be disposed of through connection to the Airport Parkway municipal treatment plant and the South Burlington City Planner has stated that the treatment plant has the capacity available to service this subdivision (Exhibit #64). Connections to this sewer line will be provided for two existing residences (Exhibit #9 and testimony of applicant). A Certification of Compliance has been issued which the Commission accepts as evidence that the disposal of wastes meets the applicable Environmental Protection Rules for connection to a municipal treatment plant and will not result in undue water pollution (Exhibit #67). 5. The site slopes gently eastward and the soils are clays. Stormwater runoff from the curbed roadway will be directed into catch basins designed to remove floatable and settleable solids prior to discharge in the existing wet area. This stormwater water system has been sized to #4CO530-1 Findings of Fact Page 4 carry runoff from the 10 year, 24 hour rainfall (Exhibit #11). A Temporary Pollution Permit has been issued, which the Commission accepts as evidence that the project complies with applicable Water Resources Department Regulations (Exhibit #12). SECTION 6086(a) (1) (C) WATER CONSERVATION: The Commission finds that this subdivision utilizes the best available technology for water conservation in residential buildings. The finding depends on and is supported by the following: 6. The protective covenants require the installation and maintenance of water conserving plumbing fixtures in any house constructed on these lots (Exhibit #61, Items 4.b and 4.c). >ECTION 6086(a) (1) (D) FLOODWAYS: The Commission finds that this subdivision will not be located in the floodway or floodway fringe of anybody of water because there are no bodies of water located within the vicinity of the subdivision (Exhibit #9). SECTION 6086(a) (1) (E) STEAMS: The Commission finds that there are no steams located in the vicinity of this project (Exhibit #9). SECTION 6086(a) (1) (F) SHORELINES: The Commission finds that this subdivision will not be located on a shoreline (Exhibit #9) SECTION 6086(a) (2&3) WATER AVAILABILITY & IMPACT ON EXISTING SUPPLY: The Commission finds that there is sufficient water available to meet the needs of this subdivision and that this subdivision will not place an unreasonable burden on an existing supply. This finding depends on and is supported by the following: 7. This subdivision will utilize 19,950 to 25,650 gallons per day of water. The Commission accepts the letters from the Champlain Water District and the City of South #4CO530-1 Findings of Fact Page 5 Burlington Water Department (Exhibits #15 and #16) as evidence that there is sufficient water available and that the project will not restrict nor encumber present users. SECTION 6086(a) (4) SOIL EROSION & THE CAPACITY OF THE LAND TO HOLD WATER: The Commission finds that it must require additional measures regarding soil erosion by condition to insure that undue erosion should not result and that the land area to be covered by pavement and buildings will not increase runoff significantly. This finding depends on and is supported by the following: 8. The project site slopes gently eastward and drains into an existing wet area (Exhibit #11) 9. The soils are generally clays, of the Vergennes, Covington and Livingston series (Exhibits #71 and #31). 10. Temporary soil erosion controls are depicted on Exhibit #57. They consist of a stabilized construction entrance, hay bale check dams, a temporary sediment pond at the stormwater discharge and hay bales around catch basins. 11. Permanent erosion controls consist of seeding and mulching and the stormwater system. Upon completion of the project the sediment pond will be regraded and stormwater will discharge into rip -rapped swales (Exhibits #56 and #57). 12. The applicant has not detailed erosion controls for the construction of the sewer line. The Commission will require that such plans be identified and will require that the permittee notify the Commission prior to removal of any excess earth material from the site. SECTION 6086(a) (5) TRANSPORTATION: The Commission finds that this subdivision will not cause unreasonable congestion or unsafe conditions with respect to transportation. This finding depends on and is supported by the following: 13. Site distances at the access of the new road onto Route 116 (Hinesburg Road) are 800 feet to the south and 2000 feet to the north. The design speed of Route 116 is 50 4CO530-1 Findings of Fact Page 6 miles per hour and the estimated traffic from the subdivision will be 570 trips per day and approximately 57 evening peak hour vehicle trips per day (Exhibits #9 and #20). 14. The applicant has conducted a traffic study (Exhibit #19) which concludes that the intersection of Route 116 and Kennedy Drive will operate at Level of Service A through 1988 with the traffic from this project, and that the intersection of the proposed road and Route 116 will operate at Level of Service A (Exhibit #20). 15. The Agency of Transportation has stated that the traffic generated by this development will not adversely affect traffic flows on Route 116 and has recommended the installation of a stop sign and removal of brush at the access of the new road with Route 116 (Exhibit #21). The Commission will require that the applicants implement these recommendations. SECTION 6086(a) (6&7) EDUCATIONAL & MUNICIPAL SERVICES: The Commission finds that this subdivision will not place an unreasonable burden on the ability of the municipality to provide educational, municipal or governmental services. This finding depends on and is supported by the following: 16. The South Burlington Superintendent of Schools has stated that the additional students from the 57 homes will not unduly burden the system (Exhibit #23). 17. The South Burlington Fire Chief and Police Chief from the 57 homes have stated that the services of their respective departments can be provided to this subdivision (Exhibits #25 and #26). 18. The applicants will construct the road and all utilities to city specifications and the roadway and utilities will be accepted by the City upon satisfactory completion (testimony of applicant). 19. The City of South Burlington will require that the applicants post a performance bond (Exhibit #63). SECTION 6086(a) (8) AESTHETICS, SCENIC BEAUTY, HISTORIC SITES & NATURAL AREAS: The Commission finds that the subdivision will not have an undue adverse effect on the scenic or natural beauty of the area, aesthetics, historic sites, or rare and irreplaceable #4CO530-1 Findings of Fact Page 7 natural areas. This finding depends on and is supported by the following: 20. Historic sites, necessary wildlife habitat and rare and irreplaceable natural areas will not be affected by this project (Exhibit #28 and #29). 21. The present site is meadowland. The project will be landscaped as outlined on Exhibit #58. The applicants agreed to include in the protective covenants an item which requires the continued maintenance of the landscaping. The landscaping for this subdivision will include approximately 160 trees with a spruce screen between industrial and residential areas. 22. The City of South Burlington has required that the applicants post a $30,000. performance bond for landscaping (Exhibit #63). 23. The applicant plans to install "Town and Country" exterior lighting fixtures. Because these fixtures broadcast beyond the street area to be illuminated, the Commission will require that the applicant submit details for a shielded exterior light fixture and will not approve the "Town and Country" fixtures. 24. The exterior of the residential building will be reviewed by an architecture control committee as required by the protective covenants (Exhibit #62). 25. A project sign, which will be less than 30 square feet and unlighted, will be installed at the entrance and a standard street sign will be installed. The power will be located underground (testimony of the applicant). SECTION 6086(a) (9) CONFORMANCE WITH THE CAPABILITY & DEVELOPMENT PLAN: The Commission finds that this subdivision conforms to the capability and development plan. kThis finding depends on and is supported by the findings noted under the subsections of this criterion. SECT'ION 6086 (a) (9) (A) IMPACT OF GROWTH: The Commission finds that the municipality will be able to accommodate the total growth and rate of growth that will result from this subdivision. This finding depends on and is supported by the following: #4C0530-1 Findings of Fact Page 8 26. The project will be phased over an estimated two years (Exhibit #63) and the Commission concludes that this phasing will provide the City of South Burlington adequate time to plan for provision of services to this project. SECTION 6086(a) (9) (B) PRIMARY AGRICULTURAL SOILS: The Commission finds that this application conforms to Partial Findings of Fact #4C0530 under subcriterion 9 (B) (dated November 12, 1984) and, therefore, that this subdivision will not result in a significant reduction to the agricultural potential of the primary agricultural soils located on the project site. This finding depends on and is supported by the following: 27. The soils on this parcel consist of Vergennes and Covington series, which are considered to be primary agricultural soils for the purposes of Act 250, or approximately 600 of the DuBois property was found to contain primary agricultural soils (Exhibit #5 of 4C0530) . 28. This application proposes the subdivision of approximately 33 acres of the 86 acre tract of land. These 33 acres are located near to Route 116. The applicant has proposed an "agricultural corridor" which will provide continued access from the easterly section of the site to agricultural land located to the north and subject to Findings of Fact #4C0530 (Exhibits #31 and #37) . 29. The Vermont Department of Agriculture has reviewed this application and has concluded that the "agricultural corridor" may produce an "agricultural open space district" within the City and further concludes that the project complies with the Commission's partial findings (4C0530). 30. The Commission finds that the subdivision of approximately 33 acres and the reservation of an agricultural corridor meets the intent of Partial Findings of Fact #4C0530. The Commission's approval is limited solely to fhe 57 lot subdivision. Prior to any further development of this tract of land the Commission will require review under this subsection. Additionally, the Commission will require that the applicant maintain #4CO530-1 Findings of Fact Page 9 the undeveloped primary agricultural soils in a manner which renders these soils continually available for agricultural production and maintains the agricultural corridor in a manner which will accommodate farm machinery. SECTION 6086(a) (9) (C) FOREST & SECONDARY AGRICULTURAL SOILS: The Commission finds that the majority of the soils on the site do not qualify a forestry or secondary agricultural soils because they are primary agricultural soils. SECTION 6086(a) (9) (D&E) EARTH RESOURCES & EXTRACTION OF EARTH RESOURCES: The Commission finds that, as no earth resources have been identified on this site, this subdivision does not involve the interference with nor the extraction of earth resources. SECTION 6086(a) (9) (F) ENERGY CONSERVATION: The Commission finds that the planning and design of the subdivision reflects the principles of energy conservation and incorporates the best available technology for the efficient use or recovery of energy. This finding depends on and is supported by the following: 31. The houses will be constructed with an insulation "R" factor of at least R-19 in the walls, at least R-38 in the roof or cap, and at least R-10 in the foundation walls. Additional measures to conserve energy include solar orientation and double glazed windows (Exhibit #62) 32. The applicants have required these insulation standards in the protective covenants and have encouraged the use of oil and gas fired heating systems (Exhibit #62, Items 4.a), 4.d), 4.e) and 4.f)). SECTION 6086(a) (9) (G) PRIVATE UTILITY SERVICES: The Commission finds that this subdivision does not involve private utilities because the road and utilities will be dedicated to the City of South Burlington upon satisfactory completion. The Commission will require that the applicant maintain all utilities as approved until they are accepted by the City. SECTION 6086(a) (9) (H) COSTS OF SCATTERED DEVELOPMENT: The Commission finds that the subdivision is contiguous to an existing residential settlement. #4CO530-1 Findings of Fact Page 10 SECTION 6086(a) (9) (J) PUBLIC UTILITY SERVICES: The Commission finds that utility service is available to this project, that an excessive or uneconomic demand will not be placed on such facilities or services, and that the provision of such services has been planned on the basis of a projection of reasonable population increase and economic growth. This finding depends on and is supported by the following: 33. The Green Mountain Power Corporation has stated that electric service will be available to this project (Exhibit #33). SECTION 6086(a) (9) (K) DEVELOPMENT AFFECTING PUBLIC INVESTMENTS: The Commission finds that this subdivision will not unnecessarily endanger the public investment or materially jeopardize or interfere with the function of the Vermont Route 116 (see findings under criterion 5). SECTION 6086(a) (9) (L) RURAL GROWTH AREAS: The Commission finds that this project is not located in a rural growth area as defined by the statute. SECTION 6086(a) (10) CONFORMANCE WITH THE LOCAL OR REGIONAL PLAN: The Commission finds that this project conforms to the local plan as evidenced by the letter from III. CONCLUSION OF LAW Based upon the foregoing Findings of Fact, it is the conclusion of this District Environmental Commission that the project described in the application referred to above, if completed and maintained in conformance with all of the terms and conditions of that application, and of Land Use Permit #4CO530-1, will not cause or result in a detriment to public health, safety or general welfare under the criteria described in 10 V.S.A., Sec. 6086(a). #4CO530-1 Findings of Fact Page 11 IV.

Members Present Paul Farrar, Acting Chairman; Leone Lansing, Michael Flaherty, William Peters Mer,,ber Absent Hugh Marvin, Chairman Others Present William Szymanski, City Manager; D,vid Minnich, Assistant City Manager; Robert Chittenden, State Representative; Bruce O'Neill, Recreation Director; William Schuele, Natural REsources Committee; Ethel Schuele, Fine Arts Committee; Ruth Poger, The Other Paper; Gayle Blood, Mark Abrams, Elizabeth Edwards, Edith Hendley, Nan Frymoyer, Bradford Shaw, Bob Furlong, Lowell Krassner Comments and questions from public not related to items on Agenda There was no discussion in this area. PUBLIC HEARING: Application of Homer & Marie Dubois fora planned unit development located ofT the east side of Hinesburg Road approximately mile north of Van Sick en Road Mr. Farrar explained that this procedure is required because development of the Southeast Quadrant is allowed at a density of 2 units per acre only if the developer can prove that -such development will not have an undue impact on the community. Mr. Trudell, the developer of the parcel, then updated the development plans. He advised that the three parties involved had gone to a hearing regarding 119B." and had received the Findings of Fact from that hearing.. The findings indicated that development was to be undertaken using agri- cultural corridor concepts. The plan now calls for a 57-lot subdivision on almost 35 acres. The new layout has no cul de sacs as the first layout had had, and the road is now straighter. There will be a 12" water se -vice which will continue into the project. Sewer service is available at the Mitel pumping station, and Mr. Dubois is now negotiating with Green Acres as to where the sewer easement will be. A right-of-way will connect with the Green Acres parcel. The Plannin_; Commission had asked that the road connect into Highlanci Terrace, and this has been added to the plans. The project his been submitted to the Agency of Transportation, and a go-ahea;i has been received penciin`; Act 25C approval. Additional screening has been provided on the border of Mr Toutant's property. ApAlk.':... February 22, 19814 Page 2 Mr. Peters raised the question of development of adjoining land. Mr. Trudell said that Mr. Goodrich thinks his lot will be de- veloped as industrial, and a buffer strip is planned between t'ie two properties. Mr. Farrar asked whether the approval being; sought is for the entire concept or just this first phase. fir. Trudell said only this phase is being considered now. The remaining parcel will still meet the criteria for PUD development. At present, the second phase development would be condominiums. Mark Abrams of Highland Terrace questioned the extension of Highland Terrace. He read a lead a letter into the record (attached) citing increased traffic and air pollution and reduced safety, especially for the young children on Highland Terrace. It also noted that the extension would give access to only 4 homes, which is a marginal benefit. The extension was requested based on the arising of simultaneous emergencies, and the residents feel this is not likely, especially in view of the dangerous intersection which is a more immediate danger. The asked that if such a road extension is passed that the road be a 12 foot gravel road with chains at each end and a sign indicating for "Emergencies Only". Edith Hendley of Highland Terrace cited the dangerous access that now exists and said that 57 more families competing will make it much worse. Mr Ward noted that the approval included the provision that when the DuBois property was developed, the extension of Highland Terrace would be built. The present development cannot be ap- proved without a second access road. He added that with the extension, there will be better site visibility. Mr. Farrar suggested that in the future, it might be to everybody's benefit if the second access could be put to the north on Green Acres, and it might be better to close the Highland Terrace access and use only the new ones. Ms. Blood wanted to know the type and value of the homes to be built. Mr. Trudell said they do not yet know whether the lots will be sold individually, in groups or to one developer, and the style will depend upon the buyer(s). He felt that the homes would be a minimum of 375,000. Regarding power lines, these will. be unc4erground with the exception of a pole and the area near the pipes where vehicle traffic Would cause damage. He added that if they can find someone who knows where the pipes are, they would sleeve them. Mr. Furlong questioned why there is to be screening behind the Toutant property and nowhere else. Mr. Trudell noted that Mr. Toutant is planning to expand his bird farm operation. Mr. Schuele questtned the selling off of individual lots noting that once you do that, your PUTD is not "planned" at all. Mr. Farrar said that approval is only for specific size lots, street locations, etc, not for individual homes. Ying Lui asked how effective the access route to Highland Terrace will be in the early phase of the development. Mr. Farrar said ha personally vie.�e�j thf, access_ t.() the r� urth a:, the true secondary access. C I'fy C0UINC I1. February 22, 1984 . page 3 Mr. Shaw questioned the sewer, capacity noting they are nearing capacity with half of the development. Mr. Farrar advised there will be a bored issue to upgrade tiie cskedity and rquality the of the Airport Parkway plant. Mr. Furlong el allotment has been left in tact although it is not in use. Mr. Szymanski said the Mitel allotment is reserved_ He also advised that an easement has been left between the Furlong and Toutant lands so both could hook onto the sewer. Mr. Krassner asked whether the people who buy property in the development will pay for the sewer expansion or if the rest of the citizens will be subsidizing this. Mr. Farrar said the procedure currently is that all citizens pay by means of the bond issue. Mr. Farrar then asked if they had a statement from the School Department on the impact on schools. Mr. Trudell said in a letter of November 14,-1983, Mr. Tuttle indicated no unreasonable burden would be placed on the schools. They also have approval of the Fire Chief. Mr. Farrar then asked about plan for common lands. Mr. Trudell said they would remain in Mr. Dubois name until he develops Phase II. No proposal has yet been made. Mrs. Schuele asked about minimum yardage between homes. Mr. Trudell said there will be 15-20 foot side yards and that other R-2 setbacks would apply (30 foot rear and front). is Mr. Ward said he would prepare a proposed motion addressing all of the concerns raised and would have this for the next meeting. Mr.�Trudell advised that the ruling is that the City must be a co -applicant for Act 250 along with Mitel and Green Acres in regard to the sewer which goes through their land. Mr. Flahert the meeting will be a wri or the Counc consent. then moved that the hearin be continued until March 5 1 wi h the un erstandin that there er tten proposed motion from the Acting City P nani ;l t7 act upon. Ms._ Lansing seconded with unanimous Review of 1984-1985 Budget Mr. 01'Neill explained the capital expenditures the -Recreation Department was requesting. These include 1$5,000 for renovation f the high school tennis courts which need a major overhaul, ofor insulation of the O'Brien Center, and additional $the funds for painting and. repair of the O'Brien building. Mr. er report on the potential Farrar asked that the City Manag energy savings from the building insulation at the next meeting. Mr. O'Neill. noted that there his absmall en a few smalprdonations, tee for ivate use °f the buildin� and that t There is very little change in the Fine /rts budget, mainly an increase in salary for returning summer employees. Mr. Farrar raised the question of overestimating summer help salaries. / CI IY COUNCIL The South Burlin-ton City Cou:Icil held a Monday, March 5, 1984, at 7: 30 pill, it, the City Ball, 57' Dorset Street. ? e i+IlS1Tl Paul Par'r:1r' Yi1 L- L".i:n .,(• _E.'- .'ILiC;C1 Marvin, i;hi_lirrnan, I on-.; ... �, , ,-X.,:::ber Absent. - Michael FIah4rr-t'y; Ot:•:crs Presen .

He explained that this was a special case because the proposal is in the Southeast Quadrant which requires dual approval. This meeting will consider the sketch plan; at subsequent meetings, the Planning Commission will review the preliminary plat; if that is approved, the City Council will review and consider ap- proval; if the Council approves, the Planning Commission will then see the final plat. Mr. Mona noted for the record that the application is being reviewed under Sect. 6.60 of the Zoning Ordinance. Dick Trudell, representing the Dubois, explained that there had been a previous proposal for a 3-party development consisting of lands owned by Green Acres, Michael and Dubois. At that time, the 3 parties went to the District Environmental Commission for review under criteria 9B, which is primary agricultural soils, and received a permit under that criteria for a concept of ag- ricultural corridor development. The Dubois parcel is now able to proceed with development. What is planned is a development consisting of 62 single family dwellings and 110 multiple dwelling units. The best agricultural soils have been preserved for ag- ricultural use. The area on the ledge is being utilized for the single family homes. A roadway will run through the two sections, with some smaller streets branching off from it. Au ,ust 2, 1983 page 2 1] Single family lots will be about 1/3 of an acre. The rear lots will be served by a gravity sewer while the front lots will re- quire a pump station. Water will be brought in by an extension of the 12" main from Mitel. The development-will lehave city acres, streets throughout. The total area is approximately with an average density of 2 per acre. The density of the multi- family units will be 10 per acre. Mr. Szymanski said his major concern was with the number of cul- de-sacs at the ends of the smaller streets. These hinder snow removal and school bus maneuvering. He noted there are also too many driveways off the cul-de-sacs, as many as 6 in one instance. Mr. Marvin added Mr Trudellat the lsaidrheruck wouldlght haveatoohave check withlthe in that area. Fire Department on that. Mrs. Hurd asked who would own the agricultural land. Mrs. Maher ed o the r. said she felt theelanddshould be jointly to all dthe tCity. tenantsmightMtieFarrar it up said deedingng even tighter. Mr. Jacob said it was too bad the whole area couldn't be on a grid system of single family dwellings. He felt South Burlington had done its share of condos, and would like to see some good neighborhoods again. Mr. Trudell said they would prefer that arrangement but are trapped by the economics. Mrs. Maher said she had nothing against the mixed neighborhood concept. Mr. Mona asked for the record whether there had ever been before these two bodieeSaaPr�hesathenaexistedhenn SpitZrmaidetiherehhad zoning ordinanc Y not been. Mr. Poger noted that it is preferable to keep a lot of traffic out of a private neighborhood, and it would thus make more sense to put the condos up front. Mr. Trudell said they felt the single family homes are more marketable. Regarding the agricultural issue, Mr. Spitz said the State seems to be going along with their concept. He added the Planning Commission had hoped to tie in better with the 50-acre concept; however, since the State will also be looking at farmland, the th oorich back piece that much smaller lots will hG willbeadjpacenttoclarger lots. stressed Mr. Poger asked whether there are any problems with rights of way. Mr. Trudell said they are in the talking stages, but nothing has been firmed up as yet. Mr. Szymanski asked whether they are planning to tie in with Highland ndTerrace. Terrace were notTrudell pleasedsaid witht some of the neighbors on that idea. Regarding the open land, Mr. Poger stressed that this will have to be tied up. Mr. Spitz noted that the City Attorney has pro- posed a conservation agreement for Shelburne which could apply August 2, 1983 page 3 in this instance. Mr. Mona asked how many feet of sewer line will be involved. Mr. Trudell said about 3,000. Mr. Mona asked whether the project will have to get in line for the sewage treatment plant. Mr. Poger said they will. Mr. Poger said they need some kind of bridge between larger and smaller lots. Mr. Spitz said that in most areas there is a setback standard, usually 50 feet in cases such as this. Mr. Mona noted that this project will almost double the number of homes off Hinesburg Road and he felt that buffers should be considered. Mr. Poger said he didn't feel the question was one -F buffers but of the wisdom of putting 1/3 acre lots next to 7 or 10 acre lots. He added that he didn't think 10 units per acre is a appropriate density for the back part of the develop- ment. Mr. Spitz suggested that judgment should be reserved until the layout is seen. Mr. Poger said the only other question is to review the traffic on Hinesburg Road. He noted that a 35-mph speed limit had been proposed, but had been rejected by the State. Mr. Farrar said that the speed limit question has now gotten slightly more com- plicated. A community can change a speed limit if it can prove the change is necessary. He added that he would like to see that proof gathered this year. Mr. Mona asked whether the owner of the adjacent strip of land to the south has seen the plan. Mr. Trudell said he thought the land was in the process of changing hands. Mr. Mona said he would be concerned with the roadway along so much of the northern boundary of that lot. Mr. Schuele said that as a member of the Natural Resources Com- mittee, he would want to be sure what the plans are to preserve the open land. Mr. Farrar indicated that before he could vote for approval, there would have to be a specific concept. Mr. Mona said he would propose instructing the City Planner to check out the possibility of land owned in common. Mr. Spitz said that since the State would like to see the land kept for agri- culture, they might not want to have to deal with 86 homeowners. Mr. Farrar said tholwhat is really wanted is to preserve the character of the community and to have the land pleasing to look at. A Highland Terrace resident asked what power the two bodies have in enforcing its wishes. Fie noted that a strip of land con- taining a tree line was to be preserved in the Highland Terrace area but was subsequently destroyed. Mr. Poger said that the Zoning Officer had power to enforce but that the Planning Com- mission did not. Mr. Farrar added that if the Planning Com- mission or City Council imposes a stipulation, they can enforce it, but that they cannot enforce something a developer promises if it does not become a stipulation. He noted that in an Act 250 hearing, whatever you say you will do, you must do. Au �t 2, 1983 page 4 Mr. Trudell asked whether the cul-de-sacs are going to be a stumbling block to approval. Mrs. Maher asked whether the cul-de-sac at the end of East Terrace the standardithtsomthe is City wants. Mr. Szymanski said that even there, parked, it is difficult to get the school bus in and out. Nirs. Maher suggested that maybe a large area in the center of or thethe development might be better e 2 culfde-sacsschoolb witharoad on•on�Marvin e then suggested joining side of the property and joining the cul-de-sac with the proposed road on the other. Mr. Trudell said they wanted to maximize the number of homes and this would cut down on homes. Mr. Poger said this was not the Commission's concern; the question was one of traffic flow and public services. Mr. Audette noted that the cul-de-sac at Brookwood is the only one where public vehicles can get 0 feet). Both Mr.e it is larger Szymanskinand the specifications call for (30 feet). Tars. Maher indicated that they liked Mr. Marvin's idea of coni)ect.ing the cul-de-sacs. rger Concerning the question wof ler thelpre-edxisting lotsjacnt to acouldlats, the question was raised whether lots ntly some time be developed ttesaidetheysity couldsnotesince Pheyehave being considered. Mr. Spitz less than 50 acres and thus do not qualify under Section 6.60.

Q. Box 308 14 N. Meadow Road Williston, Vermont Attn: Kim Cooley R(-:,: Homer DuBois Housing Manhole Testing Dear Kim: On December 1.0, 11, and 12, Pipeline Services Company undertook manhole teetlAg at the Homer DuBois Housing Site (Ledge Knoll) on DuBois Drive. Manholes were plugged and filled for 6 hours with a "topping off" of the manholes in some cases after 1 hours time. The following results apply., M11 #10 84" Filled to top of cone - no drop MH #9 138" filled drop to 136"'- M11 #8A 137" filled drop to 132"- D1111 #8 95" filled no drop Mlf i'i 7 118 " filled no drop M11 #6 118" filled no drop MH # 5 103" filled no drop MH #4 114" filled - drop to 112" MH #3 10 5 " filled no drop MH #2 148" filled no drop MH #1 140" filled no drop On January 9th and 10th, Pipeline Services repeated the same procedure on the off site sewer manholes coming from DuBois Drive X-country through Mitell Manufacturing's Site. The following results appiv: MH #1 63" filled drop Jill overnight to 52" (18 hours) MH #2 72� filled - drop to 53� 1.8 hrs. MH #3 110" filled - drop to 94" 18 hours. M11 #4 62" filled - drop to 27" 18 hours. MH #5 50" filled -- drop to 36" 18 hours MH #6 could not fill manhole MH #7 35.5" filled - drop to 25.5 3 hours MH #8 35.5" filled - drop to 23.5" 1.5 hours I cannot explain the difference in performance of the manholes except to say either different pourings or different construction handling. It would appear that the joints in the riser and cone sections are the most prevalent source of leakage; however, in manhole #6, there is a hole AirTesting * ContreteCor, Waterline Testing * T.V. Internal Inspection - Jet FItishing * Reh;tbilitalion -2- which would not allow it to be filled. In manhole Vs 1, 2, and 3 the leakage did not go down sufficiently to determine if the leakage was at a joint. It could, there- fore, be a pressure leak or a leak in the cone section. If I can be of any further assistance, please let me know. Thank you. RGP/cb CC: H.L. DuBois Excavating Sincenly, R hard G. Perez, 2 esident lj'�rmont Pipoline Services, inc.
