Particular attention has been paid to the areas adjoining Wellesley Grove Condominium project and the southwest corner of the development at Hinesburg Road. For review, the author had plans provided by the applicant, Pat O'Brien, prepared by Krebs and Lansing Consulting Engineers, Inc. A full set of development plans and pre- and post- development stormwater plans were available and utilized. Also provided were calculations for the 25-year storm event, under both pre- and post -development conditions. Different computer models were used in the preparation of this report, and that prepared by the applicant. TR-55, Urban Hydrology for Small Watersheds, was used in the preparation of this report. This model has long been the standard for calculating peak discharges and is authored and maintained by the Natural Resources Conservation Service (formerly Soil Conservation Service) of the USDA. The applicant used PondPack, a private domain software package that uses the same computational model as TR-55 for its basis, though it is more flexible in its application. Other in-house computer models were also used in the preparation of this report. Study point 5 was selected as an area of particular interest to the adjoining property owners of Wellesley Grove condominium owners. Study point 5 is at the Southwestern corner of the development, at an existing, poorly defined ditch along Hinesburg Road. Currently this point receives discharge from approximately 5.5 acres of the O'Brien Home Farm, a mix of woods and meadow. An undetermined area further to the south and west drains along Hinesburg Road to this area as well. Following construction of the initial phase of the development, the study point will receive drainage from approximately 17.25 acres, 12 of which are not yet proposed for development. Approximately half of the developed portion of the new drainage area drains to a stormwater detention pond (Pond 1) and the other half drains directly overland to study point 5. The portion draining directly overland to study point 5 immediately abuts the property line separating Wellesley Grove from the O'Brien property. A small Swale is proposed along this property line to carry runoff away from Wellesley Grove and toward Hinesburg Road. LineWriaht Daniei R. Maxon O'Brien Home Farm Runoff Analysis July 9 2001 Discussion: Results from the independent calculations prepared for this report are in some cases similar, and in others, different from those of the applicant. At study point 5, pre - development peak discharge value for the 25 year storm was found to be significantly lower than that provided by the applicant (3 cfs v. 5.8 cfs). This difference can likely be attributed to different assumptions made in pre -development land cover conditions. The computer models' input variable for cover condition is the CN (Runoff Curve Number). The lower the CN value, more infiltration, and hence, less runoff, is modeled. Determining cover conditions is critical to the results generated by the respective computer models. The model is extremely sensitive to the cover conditions input, as different cover conditions generate different amounts of runoff. A given site would generate more runoff as conditions range from healthy forest (CN = 30) through poor forest to healthy meadow through poor pasture, and into turf, and finally, pavement (CN = 98). I believe it is critical to use conservative values for pre -development conditions, as these generate the "target" for post development peak discharge, and potential errors inherent in any theoretical modeling could result in excessive discharge to adjoining property or waterways if the "target" is not low enough. For existing cover conditions input to the model, I used slightly more conservative assumptions than the applicant. For the open space, I used meadow: defined as continuous grass, protected from grazing, and generally used for hay. The applicant used fair pasture: defined as continuously grazed, with 50-75% ground cover. For the wooded portions of the drainage area, I used woods, good condition, defined as woods protected from grazing, with litter and brush adequately covering the soil. The applicant used woods, fair condition, defined as woods that are grazed but not burned, with some litter covering the soil. (Definitions from Urban Hydrology for Small Watersheds, Technical Release 55, Engineering Division, SCS, USDA: June 1986.) Changing the CN value obtained from these differences while holding all other variables constant is sufficient to change the peak discharge value over 100% (see appendix 3). This difference in weighted CN value (53 with meadow and good forest v. 62 for fair pasture and fair woods) is primarily responsible for the significantly different "target" values for post development peak discharge. For post -development peak discharge, my results tracked well with the applicant's. We both ended up with similar post -development peak discharge values. After routing two of the three sub -drainage areas through the pond, and combining the pond discharge value coincident with the overland flow peak discharge at study point 5, I obtained a peak discharge value of 3.4 cfs, slightly less than the applicant's value of 3.8 cfs. Given the complete development of two of the three sub -drainage areas, and the extreme regulation provided by the stormwater detention, there is less input data subject to interpretation. Given the results of the post -development peak discharge values, the fact that we arrived at significantly different pre -development peak discharge values is unlikely to have an affect on runoff characteristics along Hinesburg Road following completion of this initial Ane Wm ht Daniel R. Maxon = O'Brien Home Farm Runoff Analysis July 9 2001 phase of the project. However, if future development in the approximately 12 acres of undeveloped land that currently drains into the pond should occur, and changes to the pond outlet are made which allow the peak discharge to increase much above what the current design calls for, runoff along Hinesburg may increase during a 25 year storm, relative to what is experienced today. I also examined flow quantities and velocities in the proposed swale adjacent to Wellesley Grove. Some concern had been raised by residents that runoff from the development will exacerbate existing water problems. Currently there is some sheet flow coming off Drainage area Pre4, and an existing swale points toward the eastern -most units of Wellesley Grove. This swale begins at the property corner that lies between Study points 4 and 5 (IP24) and appears to carry approximately half the drainage area of Pre4, though it was not utilized as a study point. Following development, runoff from the area of sheet flow will be diverted by the swale adjacent to the property line. The existing swale will continue to carry runoff from the development, a small area in the northern end of the so-called SWCom drainage area. Runoff to this swale will be significantly less than pre -development quantities. Runoff within the new Swale along the property line should prove to be easily contained within the swale, and at non -erosive velocities, even during a 25 year storm event. Study point 4 discharges to a wetland area on the development site, which extends into the area between Wellesley and Georgetown. Potential runoff changes were qualitatively examined here. Reduction in drainage area leading to this point from 21 acres to 2.3 acres, with very limited grading and addition of minimal impervious area, will result in a appreciable reduction in peak discharge levels for the 25 year storm event. The applicant's calculations show a reduction from 2.4 to 1.4 cfs. Given the apparent split in area Pre4 discussed above, I suspect the pre -development discharge at Study point 4 to be something less than the 2.4 given in the applicant's report, though still not below the expected post -development peak. LineWrIaht Daniel R. Maxon O'Brien Home Farm Runoff Analysis July 9, 2001 Conclusions and Recommendations: At Study point 5: I believe the applicant has over -estimated the pre -development peak discharge value for the 25 year storm event. Though this should have little, if any, impact following completion of Phase I, care should be exercised in review of future phases of the project. Earthwork should continue along Hinesburg Road to the west-northwest as far as the culvert carrying flow under the access drive to Wellesley Grove Condominiums. There appears to be approximately 3-4 feet of drop between the property line and the culvert, sufficient to better define the ditch through this area, and better convey stormwater runoff. At the property corner between Study points 4 and 5: When final grade is accomplished in this area, care should be taken to insure runoff from the northern end of drainage area SWCorn does not reach the existing swale just on Wellesley Grove property and immediately behind the nearest Wellesley housing unit. This may entail the construction of a small berm if grades do not allow continuation of the proposed swale along the property line. LineWrignc Daniel R.

Mr. Farley moved to approve the Consent Agenda subject to the stipulations in the Administrator's memo of 6 July. Mr. Cameron seconded. Motion passed unanimously. 4. ;Public Hearing: Preliminary Plat Application #SD-01-34 of Daniel & Lee O'Brien, DBA Forest Park Realty Corp. and The O'Brien Family Limited Partnership for a 101 unit planned residential development and a six lot subdivision, Hinesburg Road and Kennedy Drive: Mr. Dinklage noted that the Board received a letter from Tom Crowley, President of Georgetown Homeowners' Association indicating that they had agreed on a chain link fence. A letter was also received from Mark Hall representing Wellesley Condominium Association asking for time to do a traffic study and stormwater survey. The Board also received a traffic study done by the applicant. Patrick O'Brien then presented the plan. He said the proposal is to subdivide the property into 6 lots. Lot # 1 would be 8.1 acres and would contain the Stonington Circle town homes. Lot 42 would be 5.3 acres and would consist of the Lancaster Lane apartment buildings. Lots 3 & 4 would remain open and would be given to the city for recreation purposes. The remaining parcels would. be left in their natural state. Mr. O'Brien indicated a future potential connection to Old Farm Road. Mr. Belair noted this is on the official city map. Mr. O'Brien noted that the maximum allowable density is 111. They propose 101 units. DEVELOPMENT REVIEW BOARD 10 JULY 2001 PAGE 3 Mr. Dickinson then addressed traffic. He said that traffic would access onto both Hinesburg Rd. and Kennedy Drive. Trip generation was calculated on the basis of the town houses being single family houses and the apartments being condos. The estimate for AM peak hour trip ends is 66 and for PM peak hour trip ends is 90. Mr. Dickinson said they estimate that 73% of the cars will go via Hinesburg Rd; 27% would go via Kennedy Dr. The Kennedy Dr. access would be limited to right turns only both in and out. By adding the proposed trips to the Hayes Ave. intersection, the level of service would be at "C". With today's conditions, the Kennedy Dr./Hinesburg Rd. intersection would be at level of service "E." With the proposed improvements, it would go to "D." Mr. Dickinson said they feel this project would have a minimal impact on level of service. Mr. Dickinson then outlined some recommendations to mitigate the added traffic: a. incorporate a median on Kennedy Dr. to prevent left turn movements b. add a left turn lane on Hinesburg Rd. for southbound traffic entering this project c. make sidewalk and bike path connections (Mr. O'Brien noted there will be an 8 ft. bike path in this community and showed the route). Ms. Weiner noted the city has traffic calming plans for the Old Farm Rd. area and asked how much traffic from this development would be turning south. Mr. Dickinson estimated about 2-3%. Ms. Barnard of Wellesley Grove said that even now turning left onto Hayes Ave. is a problem. She asked if that can be incorporated as part of this project. Mr. Dickinson said they probably would do that and make it symmetrical. The applicant indicated they would do this. Ms. Barnard noted that Wellesley Grove has hired a traffic consultant and would like to have this hearing continued to allow review of that study. Mr. Young asked for a diagram of what the intersection would look like. Mr. Dickson said that is not now available. Mr. Dinklage said that would be discussed in detail at Final Plat. Mr. Hiltz asked if more cut through traffic to Hinesburg Rd. is anticipated. Mr. Dickinson said the design would discourage this as would change of grade. Mrs. Maher asked what the median would look like. Mr. Dickinson said it would be a curbed island and would be done by the firm doing the Kennedy Dr. improvements. DEVELOPMENT REVIEW BOARD 10 JULY 2001 PAGE 4 Ms. Von Olsen asked about school buses and delivery trucks. Mr. Dickinson said the streets would be city streets built to city standards. Ms. Wright asked if the median would have an impact on Georgetown. Mr. Dickinson said it would not. Ms. Wright said the proposed future road includes blocking off the end of Old Farm Rd. She asked what will happen to cut -through traffic at that time. Mr. Dickinson said that is not part of this project and was not analyzed. Mr. O'Brien said the design of the road does take into consideration the grade of Old Farm Rd. Mr. Sporzynski said an 8 foot bike path has been asked for. He said the Bike Path Committee would much rather see the bike path on the east side of the street and would prefer a 10 ft. path. Mr. Dinklage noted that the city would have to complete the link between the 2 ends of the bike path. Ms. Wright was concerned that there isn't that much property at Georgetown for an 8 ft. path. Mr. Dinklage said the Board would eventually deal with that. The aim is to get bike traffic to the traffic light so they can cross safely. Mr. Kupferman asked about the semi -circular road. Mr. O'Brien said that is to connect to potential future development. Mr. Kupferman was concerned with building a road behind Georgetown that Georgetown has no access to and having a road that serves only a small group of homes. He said he would like to see what the whole area would look like. Mr. O'Brien indicated that they will contribute 2 small open space parks. Mr. Dinklage questioned whether the city wants the parks and who would be responsible for maintenance. A member of the audience asked about access to the open space lot behind Lancaster Lane. Mr. O'Brien said the intent is to have an area that will stay in its natural state. It would be for walking, etc. This land goes all the way to the bike path. There is also an easement that goes to the park. There would be a footpath, maybe a few benches. The city could do with it as it wishes. Mr. Schmitt asked about potential future build -out. Mr. Dinklage said that is not part of this proposal. Mr. Kupferman noted the open space is a class C wetland and asked what kind of use the open space piece could have. Mr. O'Brien said it would be basically a natural area. The use would be up to the city. Ms. Yankowski said there would be a lot of buildings, people and traffic and she didn't see a way for any wildlife to get between the 2 wetland pieces. DEVELOPMENT REVIEW BOARD 10 JULY 2001 PAGE 5 Ms. Yankowski also asked where the water would go that won't go into the wetlands or into Potash Brook. Mr. O'Brien said they would have a presentation on that. Mr. O'Brien said they estimate the project will generate 51 school -age children and have submitted this number to the School Board. The Homeowners Association would own and maintain the retention ponds. Mr. Dinklage said the city is undertaking an initiative to ensure that regular maintenance s being done, to these facilities. Mr. O'Brien noted that there would be no dumpsters in the Stonington Circle. In the other area, dumpsters would be enclosed in structures. Mr. Dinklage asked about the adequacy of parking for the condo area. He noted there are problems elsewhere in the city and that the applicant is asking for a parking waiver. Mr. Dinklage suggested that the required number of spaces might not be enough. Mr. O'Brien said they had miscalculated in their submittal. In Stonington Circle, parking is adequate. In Lancaster, they had left out the underground parking in garages. There are now 2 spaces per unit plus one for every 4 units as visitor parking. Mr. O'Brien showed the area for visitor parking. Mr. Dinklage noted that in many rental units there are as many as 4 cars per unit with 4 working adults living in the units. This creates a problem for the city. Ms. Gorarum asked if 4 cars per unit doesn't also affect traffic. Mr. Dinklage said it does. Mr. O'Brien then enumerated the waivers they are seeking: a. setbacks for front yard on Lancaster Lane b. setback on Stonington Circle for building #11 c. eliminate the requirement for a place to store recreational vehicles Ms. Wright asked about the appearance of the buildings. Mr. O'Brien said they would be similar in style to Wellesley Grove with the exception of walkout basements. They would be in the $180,000 price range. Mr. Dinklage said the Board wants a commitment that what is shown at final plat is what is actually built. Ms. Yankowski said that in light of the request for setback waivers, it sounds as if there are too many buildings proposed. She said if there were fewer buildings, there could be more parking. DEVELOPMENT REVIEW BOARD 10 JULY 2001 ' : C-90 Mr. O'Brien also noted they are asking for a height waiver for the 12-plexes on Lancaster. There would be 3 stories above and 1 below grade, similar to the Chatham Grove buildings. Mr. Dinklage asked why a waiver is needed. Mr. O'Brien said they worked on 8-plexes but couldn't get underground parking, and 12-plexes use up less land. The waiver would be for up to 45 ft. (5 ft. waiver). Mr. Boyle then showed the contours of the area and the building concepts for the condos. He indicated the existing treeline and the treeline that would exist after construction. A berm would be created to be sure water does not leave the property. Mr. Boyle then reviewed planting including screening of parked cars so light from headlights does not leave the property. Mr. Hiltz questioned whether pines would thin out in time. Mr. Boyle said they could use spruce. Ms. Barnard asked about lighting in the parking lot. Mr. Dinklage said there is a city standard that requires light not to leave the property. Mr. Boyle said there would be 20 ft. poles in the project and 24 ft. light poles on the street. Mr. Boyle indicated they will consider something other than lindens for the street trees. Ms. Wright asked about protecting wildlife. Mr. O'Brien said that before final plat and the state permit process, they will address endangered animal and plant species. Other animals will get along with people. A member of the audience asked why the city would want to own a piece of wetland. He noted that it would not be usable and the applicant would not have to pay taxes on it. Mr. Dinklage said it is possible this area could be expanded when other pieces of contiguous land are developed. He said the city has indicated they would like to receive this land. Mr. Boucher suggested making two of the 8-plexes into a 12-plex and eliminating one building. Mr. O'Brien said they want a -variety of building options. Mr. Burke then presented a stormwater plan. He indicated that Wellesley Grove has hired a consultant but no comments have been received yet. Soils range from ledge to stony loam to sand. Slopes go from shallow to steep. There are also 5 sub -watersheds on the property. Mr. Burke indicated their analysis was for a 25- year, 24-hour storm. He then showed the discharge points and how water would be redistributed through pipes, swales, etc. He said that water would not run directly from pavement untreated into the wetland. The run-off rate in all relevant locations would be reduced. DEVELOPMENT REVIEW BOARD 10 JULY 2001 PAGE 7 Mr. Dinklage said the application would be continued so staff can review new information just received. Mr. Boucher moved to continue the application until 21 August. Mr. Schmitt seconded. Motion passed unanimously. 5. Public hearing: Final plat application #SD-01-33 of Homestead Design, Inc., to amend a planned residential development consisting of 296 residential units and an 18-hole golf course, Dorset St. The amendment consists of minor modifications to decks, grading, buildings, etc., for the Glen Eagles project, Park Road: Mr. Nedde showed 2 versions of the final plat. He said the changes are housekeeping issues. There had been a cedar hedge proposed as a buffer to city -owned wooded area. The applicant now proposes a cedar 2-rail fence. There will be stairs from the deck of Unit 20. The decks on 2 units will be enlarged. There will be minor grading changes. Mr. Belair said staff had no issues. Mr. Cameron moved to approve Final Plat Application #SD-01-33 of Homestead Design, Inc., subject to the stipulations in draft motion dated 10 July 2001. Mr. Schmitt seconded. Motion passed unanimously. 6.

Dear Ray & all Boardmembers: Please consider this a formal request for a waiver of the front yard setback requirement of 30'. The waiver is necessary for the following buildings: Stonington Circle: Building #11 Proposed setback 14' Lancaster Lane: Building #19 Proposed setback 15' Building #79 Proposed setback 15' Building #80 Proposed setback 15' In designing this development, the decision was made very early on to protect the wetlands on this property and establish buffer zones around them for further protection. By granting this setback waiver, you will enable us to build on more of the land that is not as environmentally sensitive as the lands within and adjacent to the wetlands. It is also important to note that none of these proposed setbacks will effect the views, access or safety of the adjoining properties.

The City's Official Map designates a general area on the O'Brien property as "proposed parks and open spaces." The City has some legal rights related to the purchase and development of these designated lands. However, in this case, the map only shows a general area rather than any specific lands. There is a clear need to provide for public parks in this area. This need is articulated in the Comprehensive Plan, which calls for a "neighborhood park" in this area, and the Capital Budget. The Comprehensive Plan defines a "neighborhood park" as being optimally between 5 and 10 acres, with a focus on "informal active and passive recreation" rather than the types of organized activities and sports that create more parking and usage demand. The City's adopted standard in the Capital Budget for parkland is 7.5 acres per 1,000 residents. Full build -out of the O'Brien parcel as currently zoned would support roughly between 949 and 1,044 new residents, which works out to a demand for about 7 to S acres of parkland. 1 have shown a calculation based on both the 2000 Census data for average household size in the City (2.31), and a smaller household size more typical for the type of multi -family units proposed. 2000 Max. # of Average HH Potential Smaller Potential Zoning Acres units size population HH size population R-7 59.5 416 2.31 961 2.1 874 R-4 9 36 2.31 83 2.1 76 Total 68.5 452 2.31 1,0441 2.1 949 1 1VEMO Standard for park Projected land per 1,000 Acres Household size population residents (acres) required Smaller size (2.1) 949 7.5 7.1175 2000 Census (2.31) 1,044 7.5 7.83 City Attorney Steve Stitzel and l would recommend the Planning Commission conduct a site visit to the property soon to determine what area that is not currently proposed for development would be most suitable for park land. The site visit would be conducted as a noticed public meeting, so anyone who would like to participate may do so. Once an area of roughly 7 to 8 acres has been designated, the City will survey the area and the Planning Commission will need to propose an Official Map amendment. The amendment process is the same as for zoning amendments, with Planning Commission holding a public hearing and forwarding the proposed change to City Council. if the Official leap change is made prior to final plat submittal by O'Brien Brothers, they will need to show the designated area on their submittals. Actual acquisition of the land will need to be negotiated between the City and the O'Brien Brothers. 2 Results of Sewer Line Flow Monitoring at the Intersection of Hinesburg Road and Kennedy Drive, South Burlington 211101 Through 219101 Attachment 1 Liquid Level Monitoring: Percent Full 100% 90% , 80% 70% , 60% 50% L a 40% 30% 20% IT 10% AV P 0% 2/1 0:00 2/2 0:00 2/3 0:00 2/4 0:00 2/5 0:00 2/6 0:00 2/7 0:00 2/8 0:00 2/9 0:00 Date/Ti me U:\PROJECTS\KREBS SEWER\SBSEWER.xis 2J9/01 1000 d a a c 0 C9 M d �a E W W 10 2/1 0:00 Estimated Flows (Assuming Uniform Flow; Actual Flows may be Significantly Different) 2/2 0:00 2/3 0:00 2/4 0:00 2/5 0:00 2/6 0:00 2/7 0:00 2/8 0:00 Date/Time 2/9 0:00 U:XPROJECTSIKREBS SEWER\SBSEWER.xis 2/9/01 PAGE,1 OF 24 .

Stormwater Analysis and Plans Attachment 2 STORMWATER ANALYSIS O'Brien Home Farm SUMMARY: A stormwater runoff analysis was performed on the proposed development at the O'Brien Home Farm in South Burlington. The site is generally bounded by Kimball Avenue to the north, Old Farm Road to the east, Hinesburg Road and existing homes to the south, and Kennedy Drive and several condominium developments to the west. The overall project will consist of an area of townhouse style units and an area of multifamily units. A town road from Kennedy Drive to Hinesburg Road will serve the development. Several private roads and drives will serve the individual units. There are a variety of existing soil types on the site including Adams -Windsor sands, Farmington - Stockbridge rocky loam Duane and Deerfield soils, Belgrade and Eldridge soils, and Enosburg- Whatley soils. These soils range from classified as type A to type C soils by the U.S. Soil Conservation Service, indicating a low to moderately high degree of runoff. The site slopes from east to west, at times steeply. The pre development condition was divided into five watersheds corresponding with the natural stormwater discharge points of the property. Study point 1 is located at the intersection of Kennedy Drive and Kimball Avenue; Study point 2 is a culvert crossing under Kennedy Drive north of Windridge Condominiums; Study point 3 is a culvert crossing under Kennedy Drive south of Windridge; Study point 4 is the where Wetland A exits the property, near Wellsley Grove Condos; and Study point 5 is the southwest corner of the property in a swale along Hinesburg Road. All of the proposed development occurs in areas discharging to Study points 3, 4, and 5. The runoff outleting to Study points 1 and 2 is unchanged. An elaborate network of swales, catch basins, piping, and extended detention ponds has been designed to treat stormwater and limit post development runoff to pre development conditions. Extended detention Pond 1 is located east of the new road near Hinesburg Road. This pond will treat and detain the majority of the runoff from the townhouses and 800 feet of the new road. Extended detention Pond 2 is located west of the new road near the Georgetown development. This pond collects and treats runoff from 600 feet of new road and the northeast corner of the townhouse area. Extended detention Pond 3 is located east of the new road near Kennedy Drive. Pond 3 collects the majority of runoff from the multifamily area and 400 feet of new road. Areas of the development flowing to Study points 3, 4, and 5 without being directed to a detention pond are treated via a combination of overland flow over vegetated terrain and grass lined swales. To determine runoff and size the new extended detention ponds the 25 year 24 hour storm event was used. This corresponds to a 24 hour rainfall event and 3.85 inches in Chittenden County. The watersheds were analyzed using TR-55 methods and Haestad Methods PondPack v7 software under pre development and post development conditions. The results were as follows: Page 2 25 VEAR STORM Study Point Pre Development Peak Runoff (CFS) Post Development Peak Runoff (CFS) 1 1.0 1.0 2 3.3 3.3 3 4.4 4.2 4 2.4 1.4 5 5.8 3.8 All post development peak runoff has been reduced to or below pre development levels. In addition to detention and reduction of peak runoff, the extended detention ponds have been designed to comply State of Vermont Best Management Practices for treatment of stormwater runoff. As such, the ponds will: a) collect the first inch of stormwater runoff from the site and release it over a period of 24 hours or more; b) be a wet pond with a permanent pool; c:) have side slopes of 3H:IV; d) contain an 18" sump for sediment collection and storage. homefarmstorm.wpd 5- 4 3- 2- 0- Hydrograph Pond 125 Year Storm 10 20 30 40 Time (hrs) Currently Plotted Curves POND1 IN POND1 OUT 3 3 O 2 1 0 Hydrograph POND2 25 Year Storm 10 20 30 40 Time (hrs) Currently Plotted Curves POND2 IN POND2 OUT M H 3 3 0 2- 1 M Hydrograph POND3 25 Year Storm 20 Time (hrs) We M Currently Plotted Curves POND3 IN POND3 OUT a� W 327.5 327.0 326.5 326.0 Elev. vs. Time POND1 OUT 25 10 20 30 40 Time (hrs) Currently Plotted Curves POND1 OUT 25 326.5 - 326.0 - > 325.5 aD W 325.0 324.5 324.0 - Elev. vs. Time POND2 OUT 25 10 20 30 Time (hrs) M Currently Plotted c,urVE s .............

Box 64709 Burlington, Vermont 05406-4709 802-658-0820 Fax 802-860-1014 February 9, 2001 Mr. Michael Burke Krebs and Lansing Consulting Engineers, Inc. 10 Main Street Colchester, VT 05446 Re: Sewer flow monitoring, Feb. 2 to 8, 2001; Corner of Rte. 116 and Kennedy Drive, So. Burlington Dear Mike: Enclosed please find the results of the sewer flow monitoring which Heindel and Noyes performed at your direction in a South Burlington municipal sewer pipe located at the intersection of Route 116 and Kennedy Drive. Method: We collected one week of detailed flow data using a pressure transducer which we placed on the floor of a ten -inch sewer pipe, at a location 2 feet north (downstream) from the manhole at this intersection. Instantaneous liquid levels were recorded by an automatic data -logger at ten-minute intervals between February 1, 11:30 AM, and February 8, 11:20 AM, 2001. Weather: Temperatures during the study week were generally below freezing. A total of 9.5 inches of snowfall was recorded at the Burlington Airport during this week. Because of the cold temperatures, it is unlikely that there was a significant amount of infiltration of surface water into this sewer pipe during the study week. Results: The pressure transducer data indicate that the sewer pipe was flowing well below its capacity during our one -week study. The hydrograph of liquid levels (see page 1 of the Attachment) shows that the liquid levels rarely exceeded 40% of the full diameter of the pipe. Only once during the week did the liquid level exceed half -full; this was on February 2, at 10:10 PM, when the level reached 58% of pipe -full condition. The data indicate that the sewer pipe was less than 36% full for 90% of the time. The average recorded liquid level during the study week was at 20% of pipe -full condition (see statistics at end of summary table in Attachment). Liquid Levels versus Flow Rates: We should point out that in a circular pipe that is not pressurized, such as this gravity sewer pipe, there is not a linear relationship between the liquid level in the pipe (height of water measured up from the bottom) to the flow rate of liquids in the pipe (measured in gallons per M. Burke re: Rte. 116 / Kennedy Dr. sewer pipe; February 9, 2001; Page 2 minute for example), due to the geometry of the pipe. For example, at 58% liquid level (the highest recorded in our study week), the pipe would be at 50% of its calculated flow capacity. At 36% liquid level (the 90th percentile of our recorded liquid levels), the pipe would be at 20% of its flow capacity. At the average liquid level of 20%, the pipe was at about 7% of its flow capacity. The theoretical maximum flow capacity would occur when the pipe is 97% full. Daily Fluctuations: During the week of monitoring, the sewer flows followed a regular pattern without significant variation. Flows were lowest during the early morning hours, and were highest during the daytime. Sewer flows rose and fell sharply, presumably due to the activation of pumping stations upstream. Estimations of actual flow rates: In our experience, it is not possible to mathematically convert the liquid level measurements to accurate flow rates (in gpm, or cfs). This is because "uniform flow" rarely occurs in storm sewers, sanitary sewers, and similar channels due to the effects of pump stations, sediment, solids, and rapidly changing slopes and pipe dimensions. Without uniform flow conditions, the mathematical equations that convert liquid levels to flow rates are not valid or accurate. The most accurate way to determine flow rates over a long period of time is to measure various individual flow rates (using a calibrated weir or some other measuring device) while simultaneously measuring the liquid levels, under several different flow conditions. Then, we could develop a "rating curve" that would mathematically characterize the flow rates over a range of different liquid levels. You indicated that this level of accuracy was not necessary for this particular project, and that the important information needed was relative to the percent of pipe -full capacity in this sewer pipe. Given those cautionary statements about the questionable accuracy of predicting flow rates from liquid levels in this circumstance, we have provided estimated flow rates for this study period, using two standard formulas for uniform flow in culverts and open channels. These calculations provide an estimated range of possible flow rates each time the liquid level is measured, based on the measured liquid level, the known slope and shape of the pipe or channel, and an estimated roughness coefficient. Uniform flow theory assumes that the velocity of flow can be determined, based on the balance between gravity and resistive forces (friction). For a uniform flow to occur, the slope, shape, and depth of the flow must be constant along the length of the channel. Since these conditions do not exist in the sewer pipe that we monitored, these flow calculations must be viewed as estimates only. See the calculation brief at the end of the Attachment, and the calculation results and parameters on the 23-page summary table. Using two different calculation methods — the inlet -controlled culvert formula, and the Manning formula for uniform flow — we have estimated the range of likely flow rates under ideal uniform flow conditions. By both methods, the estimated flow rates are fairly similar. The graph at the end of the Attachment shows both the M. Burke re: Rte. 116 / Kennedy Dr. sewer pipe; February 9, 2001; Page 3 high and low end of this range of estimated flows, for each time the liquid level was measured. Summary: In summary, one week of automated monitoring of the liquid levels in the sewer pipe just north of the manhole in the intersection of Route 116 and Kennedy Drive (February 1 to 8, 2001) shows that 90% of the time, this pipe carries less than 20% of its flow capacity. The maximum instantaneous flows we recorded were about 50% of the pipe's capacity. Actual flow rates cannot be precisely determined from these liquid level measurements because the flow regime was not hydrologically uniform. However, using standard estimating formulas, we have estimated that the flow rates might have ranged from about 9 gpm during overnight hours, to about 500 to 600 gpm during high -flow times, to a single peak of approximately 950 gpm. Please call me or Craig Heindel if you have any questions. Sincerely, d _ John Per i Hydrogeologist [UAPROJ ECTSWrebs_SeweAburke tdoc] 100% 90% 80% 70% 60% U. �.

The site is generally bounded by Kimball Avenue to the north, Old Farm Road to the east, Hinesburg Road and existing homes to the south, and Kennedy Drive and several condominium developments to the west. The overall project will consist of an area of townhouse style units and an area of multifamily units. A town road from Kennedy Drive to Hinesburg Road will serve the development. Several private roads and drives will serve the individual units. There are a variety of existing soil types on the site including Adams -Windsor sands, Farmington - Stockbridge rocky loam Duane and Deerfield soils, Belgrade and Eldridge soils, and Enosburg- Whatley soils. These soils range from classified as type A to type C soils by the U.S. Soil Conservation Service, indicating a low to moderately high degree of runoff. The site slopes from east to west, at times steeply. The pre development condition was divided into five watersheds corresponding with the natural stormwater discharge points of the property. Study point 1 is located at the intersection of Kennedy Drive and Kimball Avenue; Study point 2 is a culvert crossing under Kennedy Drive north of Windridge Condominiums; Study point 3 is a culvert crossing under Kennedy Drive south of Windridge; Study point 4 is the where Wetland A exits the property, near Wellsley Grove Condos; and Study point 5 is the southwest corner of the property in a swale along Hinesburg Road. All of the proposed development occurs in areas discharging to Study points 3, 4, and 5. The runoff outleting to Study points 1 and 2 is unchanged. An elaborate network of swales, catch basins, piping, and extended detention ponds has been designed to treat stormwater and limit post development runoff to pre development conditions. Extended detention Pond 1 is located east of the new road near Hinesburg Road. This pond will treat and detain the majority of the runoff from the townhouses and 800 feet of the new road. Extended detention Pond 2 is located west of the new road near the Georgetown development. This pond collects and treats runoff from 600 feet of new road and the northeast corner of the townhouse area. Extended detention Pond 3 is located east of the new road near Kennedy Drive. Pond 3 collects the majority of runoff from the multifamily area and 400 feet of new road. Areas of the development flowing to Study points 3, 4, and 5 without being directed to a detention pond are treated via a combination of overland flow over vegetated terrain and grass lined swales. To determine runoff and size the new extended detention ponds the 25 year 24 hour storm event was used. This corresponds to a 24 hour rainfall event and 3.85 inches in Chittenden County. The watersheds were analyzed using TR-55 methods and Haestad Methods PondPack v7 software under pre development and post development conditions. The results were as follows: Page 2 25 YEAR STORM Study Point Pre Development Peak Runoff (CFS) Post Development Peak Runoff (CFS) 1 1.0 1.0 2 3.3 3.3 3 4.4 4.2 4 2.4 1.4 5 5.8 3.8 All post development peak runoff has been reduced to or below pre development levels. In addition to detention and reduction of peak runoff, the extended detention ponds have been designed to comply State of Vermont Best Management Practices for treatment of stormwater runoff. As such, the ponds will: a) collect the first inch of stormwater runoff from the site and release it over a period of 24 hours or more; b) be a wet pond with a permanent pool; c:) have side slopes of 3H:IV; d) contain an 18" sump for sediment collection and storage. homefarmstorm.wpd I 4 U 0 3 2 1 0 Hydrograph Pond 125 Year Storm 10 20 30 40 Time (hrs) Currently Plotted Curves POND1 IN �.�. ._ POND1 OUT 130, 3 0 LL 2 1 0 Hydrograph POND2 25 Year Storm 10 20 Time (hrs) 30 Currently Plotted Curves POND2 IN POND2 OUT 5 0 3 3 0 U- 2 Hydrograph POND3 25 Year Storm 20 30 40 Time (hrs) Currently Plotted Curves POND3 IN POND3 OUT a� W 327.5 327.0 326.5 326.0 iff Elev. vs. Time POND1 OUT 25 20 30 40 Time (hrs) Currently Plotted Curves POND1 OUT 25 10 Elev. vs. Time POND2 OUT 25 20 30 Time (hrs) Currently Plotted (;urVE:S ~~ M POND2 OUT 25 ........... .... .
