Cedar Glen North - Traffic Considerations The ingress and egrees"to the proposed development will be onto Spear Street (T. R. #19) 2,100' South of the Swift Street intersection in South Burlington. The access road, Cedar Glen Drive, will lie West of Spear Street. The sight distance :Forth along Spear St. from the pro- posed intersection is about 950'. The sight distance South . along Spear St., which is essentially tangent at.the intersec- tion point, is more than one fourth mile. From traffic counts conducted by the developer this spring, the peak morning traffic flowon Spear Street approaches 160 vehicles per hour. About 83; of these are travelling northerly as would be expected. The peak evening traffic flow approaches 173 vehicles per hour. Sixty Six percent (666) of that traffic is travelling southerly. The proposed adult neighborhood community Cedar Glen North, will consist of about 220 condominium type living units expected to house an average 1.7 to 1.8 persons per unit. Past experience has shown that there will be less than one vehicle per unit. It is expected that the residents, age 52 and older, will not have the stereotype set patterns; such as, off to work at h 3:00 A'?. It is anticipated that these people may use their vehicles a maximum of twice a day and that this vehicular :nove- ment will be uniform during a 12 hour period 7 AM to 7 PM. Assu_*ning 220 vehicles make 2 trips over a 12 hour period would increase the peak evening hourly traffic to 210 vehicles per hour. This traffic volume should not be considered exces- sive for Spear Street which is capable of handling substantially larger traffic volumes -than that.

(802) 86A 0126 October 1$ , 1972 City of South Burlington 1181 Williston Road South Burlington, Vermont 05401 Attention: Mr. William J. Szymanski, City Manager Re: P. A. Job No. 7223 Gentlemen: In accordance with your letter dated 13 September 1972 requesting a study of two sewers in the Shelburne Road area, we now present our report and drawings showing the results of our studies. To determine the present flows and future capacities Of the existing lines discharging to the Imperial Drive and Laurel Drive sewers, the following gagings and surveys were made. IMPERIA]. DNIVE SEWER On the morning of Tuesday, 26 September 1972 at 11:30 an electronic recording device, manufactured by \I3 Pro- ducts, Inc., was installed in manhole number 2 on Imperial Drive (Scc aLL.iched sketch plan for location) . The recordL c remained in Lhe sewer until 10:10 .,.m. the following Monday, 2 OCLObcr .'.72, during which time a constant recording of t:;e depth of :low through the manhole invert was made. October 11, 1972 City of South Burlington Page 2 The weather during this period was predominently dry although heavy rain did occur on Friday, 29 September during the evening hours. A sudden increase in the recorded depth at about 8:30 p.m. could represent some water entering the sewers from illegal roof or other connections. Throughout the complete period of gaging,the maximum reading which oc- curred fairly regularly in the morning and evening,did not exceed 43% of the scale on the recording tape. When corrected from the conversion curve supplied with the instrument, the flow in the pipe indicates a maximum depth of 30% of the pipe diameter. During the period when the instrument was recording,a survey was made of the road profile and the manholes were opened to measure the depth to each invert. The fall between manholes was thus determined together with the gradient for each length of sewer. From the gradient of the length of sewer immediately upstream of manhole 2, the recording poi::L, a slope of 1 foot fall in 18.2 feet was measured. With this gradient a theoretical velocity of 11 feet per second would result with the pipe flowing full or half full. However, with only 30% of the pipe carrying flow, which was the maximum depth recorded, the proportional velocity reduces to 0.77 of the theoretical half full or full velocity,which is 8.36 feet per second. The theoretical proportional discharge at the same depth of flow is 0.19 of a pipe flowing full. An 8 inch pipe flowing full with this gradient will discharge approxi- mately 180 cubic feet per minute or 1,350 gallons per minute, assuming a friction factor of 0.013 in the Manning formula. The theoretical proportional discharge at the maximum recorded flow was, therefore, 180 x .19 cubic feet per minute which equals 34.2 cubic feet per minute or 256 gallons per minute.. October 11, 1L City of South Burlington Pa go 3 However, the foregoing theoretical values are based on pipes laid at a very constant grade and with good even joints. The sewers in question were not constructed in this fashion, there- fore it was decided that the velocity should be measured over the full length of the upstream sewer. In the sewer length from manhole 2 to 3 the actual velocity at 30% depth of flow was measured at 6 feet per second or 72% of the theoretical velocity. The actual flow passing through the manhole at the measured velocity therefore equals 72% of 256 or 184 gallons per minute.

The estimated full pipe maximum capacity for this length is 328 gallons per minute. If the maximum recorded flow of 184 gallons per minute is deducted from this flow a spare capacity of 144 gallons per minute remains. Assuming each unit of the proposed newdevelo.pment is to house 3 persons and each person returns 100 gallons of sewage daily to the sewer (infiltration included) the daily will equal 300 gallons per unit. Allowing a peak rate of 5 times average flow, this would be equal to a maximum hourly rate of 1,500 gallons per day, per unit, or 1.04 gallons per minute. Spare capacity in this length of sewer will therefore be equal to 144 T- 4 or 138 units, if the pipe is flowing full. With 68% of the sewer permitted as the maximum depth of flow the spare capacity in the sewer will reduce to 262 - 184 = 78 gallons per minute and the number of new units which can then be co mected will be equal to 78 or 75 units. LAUREL DRIVE SEWER The gaging in the Laurel Drive sewer was carried out in the same fashion and with the same equipment used in the Imperial Drive gaging. The equipment was installed in manhole number 2 (See attached sketch plan) on Monday, 2'October 1972 at 12:30 p.m. and gaging was continued until 8:40 a.m. the following Monday, 9 October 1972. The weather was again pre- dominantly dry except for Saturday when fairly heavy rain October 11, 1972 City of South Burlington Page 5 continued throughout the day and during the evening. No obvious increase in flow occurred and it can be assumed that no illegal connections are affecting the flow in these sewer lengths. The maximum depth recorded on the flow recorder tape during the whole period was 52% of scale reading for a period of approximately 30 minutes on Thursday morning be- tween 7 and 8 a.m. When corrected for the instrument,using the curve provided, the depth of flow indicates a maximum of 39% of the pipe diameter. From the gradient of the length of sewer immediately upstream of manhole 2, the gaging point, a slope of 1 foot fall in 82 feet was measured. With this gradient a theoretical velocity of 4.15 feet per second would result with the pipe flowing full or half full. However, with 39% of the pipe depth carrying flow, the maximum recorded theoretical proportional velocity reduces to 3.7 feet per second and the theoretical proportional discharge to 0.32 of a pipe flowing full. An 8 inch pipe flowing full at the above gradient will discharge approximately 86.9 cubic feet minute which is equal to 650 gallons per minute. The theo- retical proportional discharge at the maximum recorded flow was therefore 650 x 0.32 or 208 gallons per minute. The theoretical values are again based on pipes laid true to grade and with good even joints. These sewers,like those in Imperial Drive, do not have velocities equal to the theoretical velocities. The actual velocity recorded with flows at less than half pipe depths was measured at 2.1 feet per second or 57% of the theoretical velocity. The actual maximum flow measured through the gaging manhole was therefore 57% of 208 or 119 gallons per minute.

From the above table it can be seen that the sewer with the smallest carrying capacity is the length between manholes 7 and 8. The estimated full pipe maximum capacity for the length is 232 gallons per minute. This length of sewer is, however, a considerable distance up the line from the gaging point and therefore it would not carry the maximum flow measured. However, assuming this flow did occur at this point, the pipe October 11, 1972 City of South Burlington Page 7 would still have additional capacity for 232 - 119 or 113 gallons per minute. With a maximum hourly rate of 1.04 gallons per minute from each of the proposed new housing units the spare capacity would provide for 1113 or 109 units. Likewise, if the maximum depth is limited to 68% of the full depth the spare capacity will equal 185 - 119 or 66 gallons per minute which is equal to 616 or 63 housing units. SUMMARY To summarize the above data, we estimate that the Imperial Drive and Laurel Drive sewers can handle the follow- ing additional housing units without any major changes except perhaps the shelves should be raised to contain the flow within the pipe channel. IMPERIAL DRIVE LAUREL DRIVE 138 housing units if sewer length MH 1 - MH 2 is allowed to run full. 75 housing units if flow is restricted to 68% of pipe depth. 109 housing units if sewer length MH 7 - MH 8 is allowed to run full. 63 housing units if flow is restricted to 68% of pipe depth. We calculate from the low flows recorded during the night that the infiltration rates into the sewers are as follows: IMPERIAL DRIVE' Infiltration Peak Sewage Flow Total Flow 76 GPM = 41% 108 GPM = 59% 184 GPM Peak hourly water demand at 5 x average rate based on last 3 month period with 80% returned to sewer =105 GPM October 11, 1972 City of South Burlington Page 8 LAUREL DRIVE Infiltration Peak Sewage Flow Total Flow 22.5 GPM = 19% 96.5 GPM = 81 119.0 GPM Peak hourly water demand at 5 x average rate based on last 3 month period with 80% returned to sewer = 98 GPM All of the above information is based on the information currently available. No estimate can be made regarding the infiltration which may occur in these sewers during the spring thaw when the water table is usually considerably higher.

Job No. 7223 Gentlemen: Further to our recent report on the sewers in Imperial Drive and Laurel Drive, we now submit further information on the elevation of the Imperial Drive sewer relative to the existing 12" sewer in Shelburne Road. The information was compiled from actual invert elevations where manhole covers could be removed. The invert of the Shelburne Road sewer opposite Imperial Drive was calculated using a gradient of 2.533% from the lower manhole. The upstream invert could not be obtained because the cover has recently been paved over.

All under.C-round utilities are to be turned over to the City of South Burlinr-ton for maintenance and operation. 3.

Parkirg - there is inadequate parkin`• at Cedar Glen T:orth, Cluster "C". A small parkins lot has been built by the road east of Cluster "C" for their use. Should Cluster "C" lose use of this parkin* lot, parkingr on the roadway will be inevitable . 3 It is oexpected that item .13 above will reveal a myriad of problems which must be solved before the Glenwood project car, proceed, i.e., there :is not a right-of-wav for the sewer to cross Cedar Glen North,_ Cluster "C" property to Laurel Hill.

Burlington, Vermont 05401 Dear Bill: The proposed Glenwood Development (formerly Cedar Glen North) has been a matter of controversy for a considerable length of time. The meeting be- tween you and the residents was made a condition of preliminary plat approval to resolve as much of the controversy as possible and to identify those matters still unresolved. Your memo is not clear as to whether resolution was reached or what remained to be clarified. R. Gucciardi's letter did not clarify the results of the meeting either, but it referenced another meeting to be held. For what reason? I recognize that the legal, technical and neighborhood complexities involved take a lot of your time, but I hope -they can be resolved. There is just enough confusion that I -do not feel I can approve the project at the next step. I am further convinced that more Planning Commission public hearings will be exercises in frustration (for all parties) unless the air is cleared. If it is the intention of the citizens' group to oppose this development no matter what, that is one thing, but if the opposition relates to specific (technical) matters that can be resolved, your activity i.s warranted.. Sincerely, George J. Mona, Planning Commissioner /vm cc: W. Wessel, Chairman, Planning Commission -->S. Page, City Planner May 9, 1978 South Burlington Planning Commission Attention: Mr. William Wessel Chairman Re: Glenwood Development Gentlemen: Per your direction a group of residents from Laurel Hill and Cedar Glenn North met with Bill Szymanski on May 2, 1978. It should be noted that although many topics were discussed no agreements could be reached since pertinent documents were not readily available. It was, however, suggested by Bill that he be allowed to meet with the city lawyer and accummulate the necessary documents and meet with us at a later date. We all agreed that a base line of the entire development (Cedar Glenn North and Glennwood) was essential in order for all parties to understand where the various responsibilities lie. For your information listed below were some of the many topics discussed and not resolved: 1. Has the developer received Act 250 approval? If so, does it reflect the current changes from the original development such as: 140'T- a. Age requirement.Y95'-- b. Drainage. C. Sewage.'', d. Water. e. Type of dwelling. 2. Did the city of South Burlington approve all of the above changes prior to the developer's request for state approval? If so, the documents were not available. Were these changes made known to the public and how/when. Bill Szymanski indicated that the changes were publicized in the newspaper and that he would provide us with the dates. 3. With regard to the sewage, the data developed by the Laurel Hill citizens (see attachment A) which indicated problem areas in the sewage system on Andrews Road, Imperial Drive and Shelburne Road was confirmed by the Paulsen Report dated October 18, 1972. It should be noted that the Paulsen Report also indicated a potential problem in the Oak Hill, Cranwell Drive sewer system. It should be noted that we the citizens asked Bill if a definitive corrective action plan was available. Bill indicated there was no plan and could not tell us when one would be available. However, he did state, the Mr. William Wessel, ChAirman May 9, 1978 Page 2 ,PG-�1 ' l- �\ sewage system would be monitored and when trouble developed they would correct it. We the citizens pointed out to Bill that this t� --Va 7; was not acceptable. We felt that the problems should be defined Q�DN� and corrected prior to further development. In two visits to �rZ.t'461 City Hall we could find no clear paper work to define who has the µ responsibility for the design and scheduling of correcting the sewage problems. It is important to note it is our feeling that without the above mentioned, it would not be possible to develop a realistic bond value. 4. The following question was asked and no answer received. How could Mr. Potter get out of his bond obligation for corrections necessary on Oak Hill/Cranwell Drive and the Andrews/Imperial Drive sewers. The purpose of this question was to insure that we did not get into the same situation in the future. In summary, when we left Bill Szymanski, he promosed to get back with us and provide us the documents which contain the answers to our questions and that he would clearly define the base line from which this new development would proceed. Therefore, we strongly recommend that final approval be withheld until suitable action is taken to resolve the above problems to the best interest of the city and citizens of South Burlington. Very truly yours, ftux". R. . Gucciardi 24 Andrews Road South Burlington, VT 05401 P.S. It should be noted that Mr. George Neal, President of the Cedar Glenn North Cluster "C" Association, was also present at this meeting, he is representing a group of (15) home owners and will address their problems under separate cover to you, therefore, this memo should not be considered to be all inclusive. I understand from Mr. Neal that he has scheduled separate meetings with Bill Szymanski to discuss resolutions to their problems.

Szymanski DATE: May 5, 1978 On Tuesday, May 2,1978, I met with representatives of Cedar Glen North, Cluster "C" and the Laurel Hill neighborhoods. They expressed their concerns as to the work completed to date on the first -phase -of the former Potter Development. That phase of work is mostly complete. A final inspection was never requested, therefore the utilities that were to be city maintained were never inspected and accepted by the City. My records show that there are some funds still being held in escrow for this purpose and for the preparation of the as built -drawings. There were questions regarding the Act 250 permit status and as to the change in the project age limit.restrictions that were removed.,,a few years ago. It is my understanding that all state permits have been issued and the age limit restriction was removed at a District Enviromental hearing a couple of years ago together with the restrictions that were a part of the condition for acceptance of the park land by the City. We discussed the sewer report prepared by Paulsen Associates. I don't feel that there has been any significant change in the area of study to warrent a new study and that the recommendations in the report be followed. Those are that the_area.sewered into the Laurel Hill Drive sewer be limited to a"maximum of 68 units after which the area in question be regauged to see what additional capacity can be'added. The Paulsen report assumes the same flow throughout the section studied. The area in question is consider- ably upstream from the point of gauging. Prior to the use of the Imperial Drive sewer section in question, which'is:at the entrance to the Shelburne Road sewer. That sewer shall be reconstructed as per the Paulsen report. In summary I feel that the portion of the utilities built be inspected by the City and the required corrections made and that the determination be made as to what will be deeded to the City. That corrections be made to the construction drawings showing the as built . That the units to be sewered by the Laurel Hill sewer be limited to 48 additional units and the section of sewer in question be re-evaluated and that the sewer on Imperial Drive be constructed prior to additional units added to that line.

Because of the concern for the s,ifety of our students, it is reciuested that sidewalks he provided in conjunction with the roads to he constructed. This will allow students to walk safely to and from bus stops.

Lucas HOPWOOD My comments pertain to details which can be shown on the final plat or included as a condition of approval. 47 BUSINESS PARK NORTH FINAL PLAT The primary issue remaining is the build -out rate of this sub- division relative to existing and anticipated traffic congestion at* the Kennedy Drive intersections with Kimball Ave. and Williston Rd. The conditions of preliminary plat approval included a provision that development be phased, with appropriate levels of service and decree of phasing to be decided at final plat review. The developer has suggested a timetable for development as follows: 1076 - 3 parcels; 1979 - 3 parcels; 1980 - 2 parcels; 1981 - 2 parcels. I concur with his contention that it is not appropriate to ap-ly a level of service standard for the follovinc reasons: 1) we have not adopted a city --,side functional roadway class- ification system. 2) the developer will be penalized by such a standard as I traffic from outside the community increases, as well as by traffic generated by projects subsequently an-. -roved by the Commission throughout South Burlington. 3) the four year phasing plan will dive the cit-y e fir:-r beseline on which to program improvements to the t",o affected inter- sections. 4) imoosition of a level of service condition. only, -ithout phasing, will force the subdivider to sell and develop tre lots as soon -as possible, before increasing congestion prevents him from co7Tpleting the project. Two cther minor issues can be resolved: first, there -.c-s a cu.-estion on soils of lot 10, viliich cen be allevietr:d by removing. unsuitable soils as necessary and replacing -.ith gocd quality fill; secondly, the alignment of access to lcts 9 and 10 (on »illiston Road), with the National Guard Road has been shown. I co not believe it is feasible or practical to require alignment of these curb cuts :ith one another, given the layout of existing property lines, as :ell as ^rude Houghton's advice that this intersection may still be signallized, despite the offset. ,eo GLErr°,'OOD See encicsed m,?_Tno from �-US and myself, plus letter from George Neal.

PLANNING COM4ISSION APRIL 11, 1978 access and Hinesburg Road is great enough to signallize the access if the city wanted. -:to: Mr. Poger said the access could rake a right angle with Williston Road and then curve and hug the property line. r. Page said Xr. Shaw had felt the only awl -ward movementP7 would be people coming left out of I e property and then turning right into White St. 3;r. Morency felt the signal at Hinesburg Road could give them time to do that. Mr. Schzucker said that the Subdivision Regulations require an angle of 800 on a street with public use, but he said this was a private right of -,.Tay and he asked tti.at the Conmission rot consider the SGO angle when two traffic engineers !rave said it is insignificant. He said the road could be altered later. _<r. �cg;er asked if it would be a hardship to rake it a right angle with 'Williston Road and N'r. Schmuc'_ker said it would. 3%r. Mona felt t^ere should be a large turning radius on the east side of the access ;here it exits to the road. SctiTucker said they would have Brace Boughton lay out the •approach. Mr. `aoclery asked if the building could be ex ended and r.r. Sch:--ucker said they Mould artificially reimpose the line t^at existed when this vas a three -lot subdivision if the Com- ission wanted, to insure that trey could r_ot ea,:nd a lot. i-r. Poger moved to close the public hearing. Mr. Morency seconded the motion, which passed with all in favor. Yr. Levesque cane in. Xr. Foolery moved that the South Burlington Planning Commission approve the preliminary plat application for a 2 lot subdivision of the Morgan _property, draw-n by Y CG, rev. 3 12/78, subject to the following stipulations: 1) The provisions in the "Agreed Statement of Facts", it - 10, shall apply, and be shown on the final plat, as appropriate. 2) Final utilities review shall be performed by the City engineer. 3) The following required imprcve_r ents are waived: streets, curbs, sidewalks, street signs, outdoor lighting, and landscaping. 4) Further development of lot 2 is predicated on level of service "C" conditions during peak pm. rcadway hour for all approaches to the Ni_lliston Road - Dorset St. intersection and the cinesburg Road - Yilliston Road - Patchen Road intersection, and upgrading of the access drive to a city street. 5) The site plan shall be a -••ended easterly side of the access road. ;e Motion was seconded by hi Morency, to show a larger curb radius on the and pissed unanimously. _Continue public bearing on preliminary plat spolication of the Glenwood_ Corporation, Kr.

PUNNING COICiISSION APRIL 11, 1978 capacity but that some improvements would be needed before it could take the lead of the -entire 200 units. Mr. Mona wondered if the improvements should be made before the construction began and Yr. Page said Mr. Szymanski did not think it was necessary to require the improvements until later in the project, when they would be needed. Ifs. Page said the Commission could require bonding at the outset of the project if they wished. Mr. Morency did not think it made ._sense to allow 92 units when the sewer could not handle them. I;',r. Boyle said that there was enough capacity for 60 units going through Cakhill Drive. After they build 50 units, they will take measurements and see if they can build any more. If they cannot, they will go into the Endrews Avenue system which has capacity for a few more units before it will have to nave improvements :jade to it, which they will pay for when the time comes. ?fir. Carl Lisman said it was important to realize that the additional units would not be started until the sewer issue was resolved. AIr. Yona asked if after the first 50 units are built, they would come back to the Commission and discuss the rest. Mr. Lisman said the City Engineer was better qualified to make the decision as to when to stop adding to the line than the Commission. :f`r. Mona did not think it would be prudent of the Commission to authorize -use of non-existent city services and I,r. Wessel said the question was whether the Commission wanted to delegate some authority or not. Mr. Morency felt it was an engineering decision and he wanted to leave it to the City Engineer. Messrs. foolery, 'Vessel and Levesque agreed. ?t',r. Xorency said the Commission could stipulate that Mr. Szymanski check the flow before he issued permits and 14r. Ilona said that would be good. ?:r. Woolery said that the lower end of the ditch on the property seemed to get filled up pretty regularly and he said that with more covered area, the runoff would be faster. Who would take care of clef-ning the drainage ditch? .'r. Boyle said it would clean itself naturally. Ifs. Donald Loser said that when that ditch came out onto his property it was at the surface level and the water was no longer chani.eled and it fanned out onto the back corner of his house lot. He said he would like the plan for runoff water to be appropriate for the maintenance of the property. Mr. Boyle said that could be corrected•at Ifs. Moser's lot line and he said the developer would do it by working on the south end of the drainage parcel. Mr. Woolery asked who would maintain the ditch on the Glenwood property and was told the developer would. A4r. Morency suggested the Commission take a look at the property and a date and time was set for that. Kr. Boyle felt there was less coverage of the land in this plan than in the previous one because the roof area is smaller and the parking lots are gravel. Mr. Wessel asked yr. *loser to beet with the developer and work out a solution for the drainage probelm for the next meeting. Mr. Poger moved to continue the public hearing until April 25, 1978 at 7:30 pm at City Hall. A`r. A;orency seconded the motion, and it passed unanimously. Site Plan Feview, conversion of Robert Hall Building to office buildir. I'.essrs. Bouchard and Pizzagalli Mr. Bouchard said that they would like to revitalize the existing old Robert Hall building for office purposes. The building is 120' x 70' cn a lot with 300' of depth and 200' of frontage. One of tl a present curb cuts (the easterly one) will be closed and t e parking spaces will be rearranged. They have 44 parking spaces and 42 are required. They are also going to landscape a 15' strip of land with trees. As far as the sidewalk, he said that usually a city will pay for Lalf of that and he suggested this be done. To: South Burlington Planning Commission From: Stephen Page, Planner Re: Next Meeting's Agenda Items Date: April 7, 1978 Morgan Subdivision I believe the only issue still unresolved is the location of the access point. I have mailed a packet of information to Bob Shaw of Wilbur Smith Associates, who will be telephoning me Tuesday with his recommendations. Glenwood Bill 3ymanski's memo regarding sanitary sewers, water supply, and storm drainage was sent to you last week. A packet of infor- mation, which addresses many of the questions raised by the Laurel Hill area residents last time, has been sent to the group's re- presentative. Also, I will be meeting with the group prior to Tuesday's meeting. With regard to traffic generation (raised at the last meeting), I estimate this project will account for .4-.8 2 way trips/D.U. during either the morning or evening peak roadway hour. Spear Street, by 1977 counts, carries 2400 + cars per day (24 hours) and during the p.m. peak hour carries approximately 270 vehicles. If roadway width remains an issue, you might consider a stip- ulation that if the road does not work out in practice due to its narrowness, that the city retain the right to require widening to a particular width retroahively. The number of anticipated school children is being re-examined by the School Board - a formal decision will be reached by the Bcerd on the 13th or 14th of this month. Robert Hall Site Plan This proposal is to convert the vacant Robert Hall building for use as an office. Total renovation costs are estimated at $15,000, the bulk of which is devoted to interior work, although there will be some cosmetic work on the building's exterior. Traffic access is improved - 1 curb cut is to be closed. Cir- culation and parking are adequate. Landscaping is improved and exceeds the requirements of the ordinance. No screening is nec- essary. The applicant has agreed to pay half the cost of constructing a sidewalk across the frontage. I feel this is appropriate due to the fact this is a building conversion, not new construction. Bill Szymanski disagrees with me, and would like the entire sidewalk installed by the developer. Total sidewalk cost is estimated at $1,000. M E M O R A N D U M TO: South Burlington Planning Commission FROM: William J. Szymanski, City Manager RE: Glenwood Development DATE: March 31, 1978 1. SEWERS: Enclosed is a summary of a sewer capacity report prepared by Paulsen Associates in October, 1972. This summary was prepared for the Planning Commission in December, 1972. Since there has not been any significant development in the area, that would effect the report, the findings should apply. 2. STORM DRAINAGE: Storm runoff will enter the drainageway flowing northerly as shown in the plan prepared by Engineers Inc. dated January, 1973. The maximum width of channel downstream can be determined by a field survey of the area where this information is requested. 3. WATER: The development is served by the City's high service system from the 24 inch Champlain Water District main on Swift Street, by a 12 inch main southerly on Spear Street and a 8 inch main to the development is approximately 100 PSI. Respectfully submitted, William J. Szymanski City Manager 71 7/7 '�- SUMMARY OF THE PAULSEN ASSOCIATION REPORT ON THE CAPACITY OF THE SEWER LINES SERVING THE POTTER DEVELOPMENT An electronic recording instrument recording sewage flow over a week period was installed in the sewer lines on Imperial Dr. and on Laurel Hill Dr. The gauge on Imperial Dr. recorded a peak flow of 184 gallons per minute. On Laurel Hill Dr. the peak flow was recorded at 119 gallons per minute. Elevations at each sewer manhole on the lines that could serve the Potter Development were taken. From this data slopes and capacities of the lines flowing full and at 68 percent were determined. Additional capacity of lines based on 68 per cent of pipe capacity is used in this summary. It was estimated that the Potter type of development would house an average of three people per unit with a peak sewage flow of 1.04 gallons per minute per unit. The most zritical line serving Laurel Hill South is a length of 62 feet parallel to Shelburne ad.where the sewer makes a 90° turn before it crosses Shelburne Rd. to the main sewer along the west side of the road. This line has a peak capacity of 198 gallons per minute less the peak flow of 184 gallons per minute or a spare of 14 gallons per minute. This would allow an additional 13 units. The next critical section is a 310' length that feeds the 62 foot length along Imperial Dr. This length has a peak flow of 262 gallons per minute, a spare capacity of 78 gallons per minute or 75 additional units. The construction of a new line in this area would increase the sewer capacity in this area by an additional 460 gallons per minute. If this were done the next critical section is a 466 foot length on Andrews Ave. Having a spare capacity of approx- mately 234 gallons per minute or approxamately 225 units. The controlling sewer line serving Laurel Hill North is a section on Laurel Hill Dr. between Black Lantern Ln. and Cranwell Pky. This line has a capacity of 185 gallons per minute. Assuming the peak gauged amount of 119 gallons per minute passes through this line which is a conservative assumption, because the line is up stream a considerable distance, the line would have a spare capacity of 66 gallons per minute or an additional 63 units. The report also states that the sewer serving Laurel Hill South has an infiltration rate of approximately 76 gallons per minute or 41 per cent of the sewerage flow. The sewer serving Laurel Hill North has an infiltration of approximately 22.5 gallons per minute or 19 per .cent of the sewerage flow. Pace 2 ie::►or a ndirn 7:e: Next meeting's Agenda Items Date: I•'larch 23, 1978 (a) The number of curb cuts on "A1's" lot will be progressively, reduced as subdivision and development proceeds, doom to a minimum or one curb cut. The Planning commission still retains the ability, under site plan review, to further restrict access to this lot. This will occur only if the use on this lot changes, or the building is e::panded - which I feel is a certainty in the foreseeable future. Similarly, the service access over the set.:er easement could be obtained zt site plan review as ,cell. (b) the ;11provements to the Dorset St. - 1-;illiston Rd. inter- section are to begin April 24. As we have previously been told, the added capacity to the Dorset Street approach will be consumed by the additional development that has occurred siInce the traffic 1y75 counts +were made Ho—,.jever, the :+illiston Road approaches to this intersection, through i4hich most I-i.das traffic will be flot•:ing, are expected to provide sufficient additional capacity for I-iidas. I feel it is the city's responsibility to ascertain whether these approaches will also be able to accomodate the development that has occurred since the counts :sere taken. (c) with regard to the accident problem in the vicinity of I;cDonaIds, I believe this is of nominal importance to 2�Iidas because this business has little or no noonti.r:ie peaking characteristic, unlike the eateries in the "gaiint1✓t" area to the tlast. I will prepare a map and list of conditions or agreements to X'aciiitate your review, and possible approval of this project Tuesca­ evening. ta�t�er►znt of facts" for more details. Refer to the developer's "s Glenwood T�apcation is restricted to the 92 unit first phase - the balance of the project will be submitted for preliminary and final review at a later date.Eonsequently, we may reach some under- standings about the conceptual lav-out of the entire project, but the scope of this review is limited to the first 92 units. I am satisfied with the layout of the project, except for minor details 1•1hich will be su imitted to you in list form, Tu= sday evening. The plan has been reviewed by the city engineer and Fire Chief. I feel compelled to take issue with the Chief' s recom_-nenoa tion for a 30' traveled way throughout. The developer has met uS halway, as you will see on the drawings, by adding graveled shoulders. I enclose oocuz:.entation for my opinion that the roadways proposed are adEouate in width. Finally, you should be aware that the building permits for this portion of the project (S2 units) are still valid for the original layout- thus, I feel the co-.- should not ta:;e too t in_lexible a stance on the simple physical rearrangement of a previously approved plan.

I would assume that the added family size would be no problem for the existing sewers in Glenwood that extend through Oak Hill Drive to MH #5. The only problem might be this section from Oak Hill Drive to MH #5 in the report and the developer is willing to test to see if adequate capacity exists after build out, of say 50 units. If capacity is limited, the remaining 20 units could be re- designed to plan with the 2nd phase towards Andrews Avenue (MH #9) which of course would mean the coirtrection of the Shelburne Road and Imperial Drive problems outlined in Paulsen's summary. I hope my understanding of the situation is correct and that the present sewers are adequate for approval of phase I, subject possibly to the condition you may wish to make that testing might be required after a partial build out.

Parch 7, 19 78 Mr. William B. Wessel Chairman South Burlington Planning Commission 1175 Williston Road South Burlington, Vermont 05401 Dear Mr. Wessel, On Friday March 3, 1978 Mr. Terrence Boyle Architect for Ceder Glen Development and I had a meeting and review the plans for phase 1 and the following was found to enable us to give proper fire protection. 1. There must be three fire hydrants avalible to each cluster of buildings. Hydrants can be set up to be used for more than one cluster. 2. Hydrants should be set up just off main road but near the road leading in to the clusters. 3. Road around ilands in each cluster must be 30 feet wide to have proper radius to turn equipment around. 4. Distant between buildings should be 30 feet apart. Over all phase 1 is well planned to enable us to give good fire protection but because of all the new construction which has been approved by the planning commision to date, the fire department is inadequate to meet the cities needs. More equipment, addition to present station, and two more paid men should be given serious consideration to assure proper protectionfor the city as a whole.

Business Park North I have met with Gordon McArthur, from the State Highway Department, and Dick Spokes, concerning traffic and on site sewage disposal, respectively. I will have additional information to present on both topics at the hearing. 2.

Chastenay Revised Site Plan This plan is for an apartment and office building (now under construction) at the corner of I-189 and Kennedy Drive, which originally showed 20 parking spaces. In order to save more existing trees, and provide a better approach to the main parking area, it has been proposed that 5 spaces be deleted. I feel this is an improvement over the previous plan, and still affords the required number of spaces (15)• 5. Glenwood Sketch Plan This is a resubdivision proposal for the former Cedar Glen North property, now under new ownership. The project entails 181 new townhouse units, in addition to the 20 existing units. The overall density conforms to the allowed density of 4 units per gross acre. The impact of the first phase (92 units) on the most critical municipal facilities is nominal because: 1) school children have already been factored in by the School Department in their estimates, 2) sewage capacity is adequate at the Bartlett's Bay treatment plant and 3) the distance from any signallized or congested intersection is so great that it would be difficult to assign any incremental impacts on traffic from this project. The situation is unchanged with regard to police and fire protection, although water line sizing and hydrant location will be reviewed by the Fire Chief. In sum, I feel the primary consideration with regard to Phase I is the physical arrangement of parking, roads, and buildings (utilities are already in). As for Phase II, both physical layout and impact on municipal services merit a thorough review. See attached sketch for location and summery of site and fringe conditions. 6. Econolodge and ICV Site Plans The 60 day time clock expires on these projects March 12 and Yarch 17 respectively. I suggest you deny these applications and invite them to reapply when the various deficiencies are cleared up. i• l r , r E M 0 R A N D U M To: Interested Parties From: City of South Burlington Re: Status of Cedar Glen North Development ':ate: 9/19/77 The purpose of this memo is to describe the status of the Cedar Glen North Development, with regard to local approvals and building permits. I General Information The project consists of 220 condominium units on approximately 50 acres and has received preliminary approval. 7.5 acres have been deeded to the city as parkland. A building permit for 92 units has been issued, of which 2V have been built. r cul-de-sac, with storm drains and water main has been constructed and accepted by the city. Sewer and water mains, plus service lines to existing units, have been installed on the north end of the property; these mains have net yet been inspected or accepted by the city. The layout of some roads and tuildings has been modified, with the consent of the Planning Commission, since the original r. . Memorandum To: Interested Parties 9/19/77 Page 2 approval was granted. � plan is on file at City Hall, showing the location of all buil-~ings and site iTTrevs^ents as an r ov.,o p d. II Phase I (Q2 units) nperoval The permit outstanding (for 71 units) is valid only for the building types and locations shown on the plan of record, provided there are no major modifications. Major modifications would include, among other things, rearrangement of roads or substantial navel areas, eas, larger units, more bedrooms per unit, or relocation of units Further construction in this phase is subject to an informal review by the Planning Commission, on a cluster by cluster basis, Landscaping has been installed only in cluster "C" and must be completed for the "hillside" units . Easements and bills of sale for the sewer and water mains must be submitted to the city. Thy following conditions are contained in the findings of ' act as amended by the District Environmental Co^'T�yss;on ^n . : r_l 15, 1977: f h' Memorandum To: Interested Parties 9/19/77 Page 3 1) The construction rate for the balance of Phase I shall not exceed lF units for calendar 1977 and 53 units for calendar 1978. 2) The developer shall remove all restrictions on the use of the parkland to which he is a party. A private road and waiver agreement will be required for all private streets, to protect the city from owning or maintaining these streets until they are upgracea to current municipal design and construction standards. Performance bonds or a suitable escrow agreement must be executed to guarantee the installation of landscaping, sewer, water, storm drainage, and related site improvements which have not yet been completed to the city's satisfaction. III Balance of the nroiect (128 units) Subdivision approval for this portion of the project has ex - Aired. Further development Mans for this portion of the property are subject to major subdivision review under the municipal subdivision regulations.

Burlington, Vt. 05401 RE: Cedar Glen Development - Potter Dear Dick: You have asked me for clarification of my letter of July 16, 1976 pertaining to the Potter Development. It is my understanding that Mr. Potter wishes to lower the age limitation for occupants in the project. It is still my opinion that there is no legal basis for the Planning Commission to review the age question. I have, however, reviewed the land use permit issued by the District Enviro- nmental Commission, and it would appear that the granting of the permit was on the basis that all occupants in the development would be 52 years of age or older. Finding of Fact No. 18 reads: "The proposed development will be an adult community and be restricted to occupants 52 years old or older. No school age children will be allowed." The District Environmental Commission also concluded that the development will not cause an unreasonable burden on the ability of the City to provide educational services. it is my feeling that if Mr. Potter wishes to change the age limitations, he will need approval from the District Environmental Commission. I would recommend that the appropriate authorities be contacted to determine whether the schools can adequately accommodate the projected number of new students resulting from a change in the age limitation. If there is a problem, South Burlington should become a party in the Environmental Commission proceedings. If you have any further questions on this, please let me know. Very truly yours, Ric-iar A.

SLAYTON Mr. Douglas Tudhope, Acting Chairman South Burlington Planning Commission 1175 Williston Road South Burlington, VT 05401 Re: Potter Development Dear Commissioners: In behalf of our client, Mr. Henry Potter, we ask you to consider the following items in recommending to the Council,who will bear the cost to rebuild the sewer lines on Shelburne Road to allow proper flowage from Laurel Hill and the proposed development of the Potter Project. In accordance with the recommendations made by Paulsen Associates, Inc. and subsequent studies by Engineers Inc. about 380' of 8" pipe, 64' of pipe sleeve and 3 manholes are needed. The estimated cost of this project, including engineering is $15,160.00. We recommend that the City undertake this project for the following reasons: 1. The sewer line when built was improperly graded so as to create a condition under which full capacity cannot be obtained. The Paulsen report also indi- cates that substantial amounts of sewer flow is from sump pumps in Laurel Hills, such flow being a result of inadequate storm drainage. 2. Since the town had accepted this construction at a past date, they are now responsible for the proper maintenance and repair (including rebuilding) of this line. Unconfirmed reports indicate that there have been times in the past when these sections of sewer line have functioned improperly. 3. Since Mr. Potter is developing his land in accordance with the zoning and subdivision regulations adopted by the City of South Burlington, and in fact would not be overburdening the sewer line if it were prop- erly constructed, it is the City's responsibility to rebuild this line. IN COLLABORATION WITH RESEARCH PLANNING AND DESIGN ASSOCIATES, INC. COOK PLACE, AMHERST, MASSACHUSETTS 01003 South Burlington Planning Commission Re: Potter Development January 10, 1973 Page 2 4. Oversights in providing adequate storm drainage in past developments has also become a burden for our client, necessitating lifting of storm water at considerable expense and diverting it to provide relief from an existing condition. 5. By providing a park on the property line of Laurel Hill south we are already rectifying a past planning error and should not be unduly burdened with correcting other planning or construction errors not of Mr. Potter's making. 6. This project will greatly benefit South Burling- ton land use and tax base (no school children, privately maintained drives, etc.). 7. This project has been stalled for approximately one year with a considerable loss in taxes to South Burlington. Time consumption has escalated the cost of the project which will be born event- ually by the residents of the development. We respectfully request that the Planning Commission take the above matters into consideration in making a just and equitable recommendation to the Council in this matter. Sincerely ours, Y'c TerJ. BTJB ell: -?0000 300 December 1, 1972 Mr. Henry Potter 1855 Spear Street South Burlington, Vt. 05401 Dear !sir. Potter: Enclosed is a copy of the report of the investigation of the capacity of the sewer lines serving Laurel Hill North and Laurel Hill South. The report was prepared by Paulsen and Associates of South Burlington and a copy %,;as obtained by Charles Diggle of hick.ock and Boardman several weeks ago. In summary the report points out that the most critical section is the 62' for 8 inch sewer parallel to Shelburne Road which has a spare capacity of 198-164 = 14 gallons per minute for 68% pipe capacity. With each unit expected to generate 1.04 gallons per minute this sewer could accumulate 14 = 1.04 = 13 units. The next critical section is on Imperial Drive between ME 1 and MH 2 which has a capacity for 75 additional units. If a new sewer line were constructed as shown on the sketch, the capacity in the area could be increased by 460 G.P.M. The critical length would then be on Andrews Avenue between ME 6 and 7 which has a capacity of appooximately 295 - 61 m 234 G.P.M. or 234 ; 1.04 - 225 units. The sewer serving Laurel Hill North has an additional capa- city of 63 units which is conservative because the assumption is made that the same flow passes through this line as was gauged at the end of the system. If there are additional questions please feel free to call. Very truly yours, William J.

Gentlemen: Mr. Will-iam J. Sz P. A. Job No. 7223 nski, City Manager In accordance with your letter dated 13 September 1972 requesting a study of two sewers in the Shelburne Road area, we now present our report and drawings showing the results of our studies. To determine the present flows and fucure capacities of the existing lines discharging to the Imperial Drive and 1,aurel Drive sewers, the following gagings and surveys were made. IMPERIAL Dlt-WE SEI.TER On the morning of Tuesday, 26 September 1972 at 11:30 an electronic recording device, manufactured by NI3 Pro- ducts, Inc., was installed in manhole nui,iber 2 on Imperial Drive (Sec attached sketch plan forlocation). The record, r rcM"iined in t:-;c sewer until 10:10 :,.m. the following ':o:;c'a�', 2 Octobl r .';72, during which time a constant recordin` of t::e depth of :Io t-hrough the manhole invert was T:,ade. October 11, 14'972 City of South Burlington Page 2 The weather during this period was predominently dry although heavy rain did occur on Friday, 29 September during the evening hours. A sudden increase in the recorded depth at about 8:30 p.m, could represent some water entering the sewers from illegal roof or other connections. 'Throughout the complete period of gaging)the maximum reading which oc- curred fairly regularly in the morning and evening,did not exceed 43% of the scale on the recording tape. .'hen corrected from the conversion curve supplied with the instrument, the flow in the pipe indicates a maximum depth of 30% of the pipe diameter. During the period when the instrument was recordi.ng,a survey was made of the road profile and the manholes were opened to measure the depth to each invert. The fall between manholes was thus determined together with the gradient for each length of sewer. From the gradient of the length of sewer immediately upstream of manhole 2, the recording poiu , a slope of 1 foot fall in 18.2 feet was measured. With this gradient a theoretical velocity of 11 feet per second would result with the pipe flowing full or half full. However, with only 30% of the pipe carrying flow, which was the maximum depth recorded, the proportional velocity reduces to 0.17 of the theoretical half full or full velocity,which is 8.36 feet per second. The theoretical proportional discharge at the. same depth of flow is 0.19 of a pipe flowing full. An 8 inch pipe flowing full with this gradient will discharge approxi- mately 180 cubic feet per minute or 1,350 gallons per minute, assuming a friction factor of 0.013 in the Manning formula. The theoretical proportional discharge at the maximum recorded flow was, therefore, 180 x .19 cubic feet per minute NAiich equals 34.2 cubic feet per minute or 256 gallons per minute.. i October 11, 19, /-- City of South Burlington Page 3 However, the foregoing theoretical values are based on pipes laid at a very constant grade and with good even joints. The sewers in question were not constructed in this fashion, there- fore it was decided that the velocity should be measured over the full length of the upstream sewer. In the sewer length from manhole 2 to 3 the actual velocity at 30% depth of flow -, was measured at 6 feet per second or 72% of the theoretical velocity. The actual flow passing through the manhole at the measured velocity therefore equals 72% of 256 or 184 gallons per minute.

October 11, 1972 City of South Burlington Page 4 From the above tabulation it can be seen that the sewer length with the smallest carrying capacity is the length from manhole 1 to 2. The estimated full pipe maximum capacity for.this length is 328 gallons per minute. If the maximum recorded flow of 184 gallons per minute is deducted 'from this flow a spare capacity of 144 gallons per minute remains.. Assuming each unit of the proposed new development is to house 3 persons and each person returns 100 gallons of sewage daily to the sewer (infiltration vincluded) the daily flow will equal 300 gallons per unit. Allowing a peak rate of 5 times average flow, this would be equal to a maximum hourly rate of 1,500 gallons per day, per unit, or 1.04 gallons per minute.. Spare capacity in this length of sewer will therefore be equal to 144 or 138 units, if the pipe is flowing full. With 68% of the sewer permitted as the maximum depth of flow the spare capacity in the sewer will reduce to 262 - 184 = 78 gallons per minute and the number of new units which can then be co mected will be equal to 8 1 or 75 units. LAUREL DRIVE SEWER The gaging in the Laurel Drive sewer was carried out in the same fashion and with the same equipment used in the Imperial Drive gaging. The equipment was installed in manhole number 2 (See attached sker_ch plan) on Monday, 2'October 1972 at 12:30 p.m. and gaging was continued ur)til 8:40 a.m. the following Monday, 9 October 1912. The weather was again pre- dominantly dry except for Saturday when fairly heavy rain October 11, 1972 City of South Burlington Page 5 continued throughout the day and during the evening. No obvious increase in flow occurred and it can be assumed that no illegal connections are affecting the flow in these sewer lengths. The maximum depth recorded on the flow recorder tape during the whole period was 52% of scale reading for a period of approximately 30 minutes on Thursday morning be- tween 7 and 8 a.m. When corrected for the instrum_ent,using the curve provided, the depth of flow indicates a maximum of 39% of the pipe diameter. From the gradient of the length of sewer immediately upstream of manhole 2, the gaging point, a slope of 1 foot fall in 82 feet was measured. With this gradient a theoretical velocity of 4.15 feet per second would -result with the pipe flowing full or half full. However, with 39% of the pipe depth carrying flow, the maximum recorded theoretical proportional velocity reduces to 3.7 feet per second and the theoretical proportional discharge to 0.32 of a pipe flowing full. An 8 inch pipe.flowing full at the above gradient will discharge approximately 86.9 cubic feet minute which is equal to 650 gallons per minute. The theo- retical proportional discharge at the maximum recorded flow was therefore 650 x 0.32 or 208 gallons per minute. The theoretical values are again based on pipes laid true to grade, and with good even joints. These sewers, like those in Imperial Drive, do not have velocities equal to the theoretical velocities. The actual velocity recorded with flows at.less than half pipe depths was measured at 2.1 feet per second or 57% of the theoretical velocity. The actual maximum flow measured through the gaging manhole was therefore 57% of 208 or 119 gallons per minute. 1 October 11, 1972- City of South Burlington Page 6 TABULATION OF ESTIMATED CAPACITY OF SEWER LENGTHS TRIBUTARY TO LAUREL DRIVE Location Sewer Length Gradient Estimated Capacity Pipe Full Estimated Capacity 68% Pipe Depth Remarks Laurel Dr. MH 1-MH 2 0.847% 432 GPM 355 GPM if MH 2-MH 3 1.22% 520 GPM 41.6 GPM If MH 3-MH 4 1.265% 532 GPM 425 GPM " MH 4-MH 5 1.41% 552 GPM 452 GPM " MH 5-MH 6 0.435% 312 GPM 250 GPM " MH 6-MH 7 0.313% 264 GPM 211 GPM — This length allows for 109 new unit with pipe full or 63 with 68% of pipe depth " MH 7-MH 8 0.238% 232 GPM 185 GPM Cranwell Ave. MH 8-MH 9 1.495% 560 GPM 448 GPM it MH 941H 10 0.502% 332 GPM 266 GPM it MH 10-MH 11 0.637% 372 GPM 298 GPM " MH 11-MH 12 0.426% i 308 GPM 246 GPM Estimated full capacity based on 80% of theoretical capacity to allow for condition of sewer. From the above table it can be seen that the sewer with the smallest carrying capacity is the length between manholes 7 and 8. The estimated full pipe maximum capacity for the length is 232 gallons per minute. This length of sewer is, however, a considerable distance up the line from the gaging point and therefore it would not carry the maximum flow measured. However, assurning this flow did occur at this point, the pipe October 11, 1972 City of South Burlington Page 7 would still have additional capacity for 232 - 11-9 or 113 gallons per minute. With a maximum hourly rate of 1.04 gallons per minute from each of the proposed new housing units the spare capacity would provide for 1�T+ or 109 units. Likewise, if the maximum depth is limited to 68% of the full depth the spare capacity will equal 185 - 119 or 66 gallons per minute which is equal to I or 63 housing units. SUMMARY To summarize the above data, we estimate that the Imperial Drive and Laurel Drive sewers can handle the follow- ing additional housing units without any major changes except perhaps the shelves should be raised to contain the flow within the pipe channel. IMPERIAL DRIVE 138 housing units if sewer length MH 1 - MH 2 is allowed to run full. 75 housing units if flow is restricted to 68% of pipe depth. LAUREL DRIVE 1.09 housing units if sewer length MH 7 - MH 8 is allowed to run full. 63 housing units if flow is restricted to 68% of pipe depth.. We calculate from the low flows recorded during the night that the infiltration rates into the sewers are as follows: IMPERIAL DRIVE Infiltration Peak SeN-.age Flow Total Flow 76 GPM = 41% 108 GPM -- 597. 184 GPM Peak hourly water demand at 5 x average rate based on last 3 month period with 80% returned to sewer ==105 GPM October 11, 1972 City of South Burlington Page 8 LAUREL DRIVE Infiltration Peak Sewage Flow Total Flow 22.5 GPM = 19% 96.5 GPM = 81% 119.0 GPM Peak,hourly water demand at 5 x average rate based on last 3 month period with 80% returned to sewer = 98 GPM All of the above information is based on -the information currently available. No estimate can be made regarding the infiltration which may occur in these 'sewers during the .spring thaw when the water table is usually considerably higher. e Very truly yours, PAULSEN ASSOCIATES, INC. r � � Arthur W.
