Box 108 Essex Junction, Vermont 05403 ZONING ADMINISTRATOR 868.7958 Re: Traffic Generation from the Larkin/Milot and Pomerleau properties Dear Craig: This letter is in response to Bill Craig's request for us to work up some traffic generation figures assuming full build -out of the Larkin/Milot and Pomerleau properties on Shelburne Road. The Larkin/Milot parcel is approximately 30 acres while the Pomerleau parcel is approximately 40 acres. Both parcels are zoned Commercial 1 which permits such uses as professional offices, retail businesses, hotels, restaurants and service stations. In the summer of 1985, Pomerleau presented a plan for a 160,000 square foot shopping center on his parcel. In October, 1987 Larkin and Milot presented a plan to develop their property into a 22 lot "business park". Milot told the Planning Commission that they want to attract interstate banking concerns, however, he did not rule out the possibility of retail uses. Based on these previous proposals, I suggest you base your numbers on some type of retail shopping center use for both parcels. Assuming a worst -case build -out, of 30%, 522,700 square feet of retail space could be developed on the Pomerleau parcel while 392,000 square feet of commercial/retail space could be developed on the Larkin/Milot parcel. The worst -case estimate for Pomerleau's parcel is much greater than his actual proposal of 160,000 square feet made in 1985. Page Z If you are not opposed, I suggest that you develop traffic numbers for both the worst -case scenario and the scenario incorporating Pomerleau's original proposal of 160,000 square feet. This would give the committee a range of potential traffic generation from a worst -case build -out to a more realistic build - out based on what was previously proposed. If you have any questions, please do not hesitate to contact me.

The report focuses in detail on the following two intersections: US 7 with Laurel Hill Drive and US 7 with K-Mart and Brewer Parkway; but, only alludes to prob,loms/ improvements at other locations, such as US 7 with Swift Street. The following comments are offered relative to this proposed project. t, IIJ,Af 'A > , 1. In general, although the Agency does not completely agree with all estimated 1985 and 1990 design hour volumes (DHV's) without the proposed project, as presented in the report, the volumes do appear to be reasonable. The Agency does not completely agree with the use of ITE Land -Use Code 823 for a shopping center with 200,000 - 299,999 gross square feet for the estimation of generated trips for the proposed project, which has a gross floor area of 160,000 square feet. ITE Land -Use Code 822 for a shopping center with 100,000 - 199,999 gross square feet would appear more reasonable and would result in over 20% more trips during the P.M. peak hour than the trips used for analysis in the report. 2. Level of Service (L.O.S.) analyses for US 7 and Laurel Hill Drive for 1985 and 1990 without the project indicated L.O.S. 'E; and L.O.S.'F', respectively. Using the trip rates for ITE Land Use Code 822, the L.O.S. for the proposed US 7/Project Drive/Laurel Hill Drive intersection with the project would be L.O.S. 'C' and L.O.S. 'C', bordering on L.O.S. 'D' for 1985 and 1990, respectively. 3. Utilizing Planning Critical Movement Analysis for signalized intersections, the L.O.S. at the US 7/K-Mart/Brewer Parkway intersection would appear to be L.O.S. 'B' bordering on L.O.S. 'C' for 1985 and L.O.S. 'C' bordering on L.O.S. 'D' for 1990, without .�. Douglas Page: 2 November 8, FitzPatrick 1985 Novi 115' i985' 3. the proposed project. These levels appear to be better than what is actually experienced at this location. With the proposed project, the levels of service are expected to be L.O.S. 'C' bordering on L.O.S. 'D' for 1985 and L.O.S. 'D' for 1990. Thus, with the project, the expected level of service at this intersection will decrease approximately 1 level for 1985 and 1990 as compared to L.O.S. without the project. Again, these L.O.S. indications may be better than what would actually be experienced. 4. As pointed out in the report, the section of US 7 in the vicinity of the proposed project access does have a high incidence of accidents and represents a high accident location. Additional traffic loadings on US Route 7 without appropriate traffic engineering improvements may only add to the accident problems. 5. The proposed access and signal layout as presented in Appendix F of the report appears to be reasonable, conceptually, except that the slip ramp traffic should possibly be controlled by YIELD signs rather than STOP signs as presently indicated by the stop bars on the layout sheet.. 6. On pages 6 and 7 of the report various geometric improvements are listed as being required to maintain L.O.S. 'C' on US 7 during 1990 DHV conditions upon completion of the proposed project. Item 4 addresses the construction of an interconnecting access directly linking this project with the existing shopping center (K-Mart) to the north. This appears to be a very reasonable improvement which definitely should be pursued. However, no traffic analyses were provided to show the benefits of such an improvement at the intersections of US 7/K-Mart/Brewer Parkway and US 7/Project Drive/Laurel Hill Drive. How much of an improvement, if any, in the L.O.S. would result? Also, on the Proposed Site Plan in Appendix A, there is another access road which appears to run west of K-Mart and touches down wifth Queen City Park Road. If this is a proposed access, what would the traffic impacts (benefits) be relative to intersections on US Route 7 with this access in place? 7. Items 1 and 2 listed on page 7 of the report address improvements incorporated in the proposed Burlington Southern Connector project. As it would appear unlikely that the latter project would be constructed by 1990, the developer would be financially responsible for any improvements cited as necessary to maintain L'.,O.S 'C' rl \ =TO . Douglas FitzPatrickrage: 3 �-,��November 8, 1985 L 7. on US 7. Some rights -of -way have been obtain $v 1� for the Pouthern Connector project, however, them � 5 �985 may be a problem using this land independent of the Southern Connector project. This matter has been referred to the Attorney General's office for consideration. 8. On page 1 of the report reference was made that "existing geometric deficiencies are a greater factor in causing traffic congestion than future increased traffic volumes". Requirement #3 on page 7 of the report states that existing curb radii at other intersections and driveways (not identified) should be increased. Requirement #5 discusses the addition of a left turn lane at the west approach (K-Mart) to the US 7/K-Mart/Brewer Parkway intersection. Again, it should be pointed out that any of these improvements would be the financial responsibility of the developer. The Agency requires that the problem locations must be identified using appropriate analysis techniques. In summary, the Agency feels that additional information is required before a decision can be rendered relative to an access permit to US 7 for the proposed development. First of all., field determinations of actual existing L.O.S. at. the US 7/K-Mart/Brewer Parkway and US 7/Swift Street intersections at a minimum should be obtained. Other "problem" locations may have to be addressed. As pointed out on page 5 of your report, "actual existing levels of service are estimated to be one or two ranges lower than those calculated, primarily due to inadequate geometries which significantly slow traffic flow". Through actual field measurements you should be able to determine the "inadequate geometries" which are affecting the level of service on US 7 and associated streets and driveways and to determine appropriate L.O.S. Also, of prime importance would be the implementation of the access between the proposed development and the K-Mart shopping center. It would appear that this roadway link would not only be beneficial to US 7 traffic flow by reducing trips between the two shopping centers, but, would also appear to be extremely beneficial to both developers by allowing consumers a safe and easy access to shopping facilities without having to travel out onto US 7. The expected reduction in trips should be determined and an analysis performed to calculate the level of service at the US 7 intersections -if this link roadway is constructed between shopping centers. Again, all improvements would be the financial responsibility of the proposed developer. If the other access road that is shown on the site plan is feasible, then a similar analysis should be performed to determine the impacts/level of service at affected locations.

We reviewed the data which we had collected since our original report concerning intersection delays, level of set -vice conditions, and the results of the detailed accident history analysis. Concerning the intersection delays and level of service calculations, our field data indicated that the operating level of service during the P.M. peak hour just before Christmas did not deteriorate below Level of Service C. Our calculations had indicated the same. Mr. Wheatley, however, continues to believe that Level of Service conditions are considerably worse, at Level of Service E and has asked us to expand the field studies and correlate them with actual traffic volumes. He has also suggested that we redo the intersection capacity analyses using the 1985 Highway Capacity Manual methods, which came out shortly after the initial study was completed. As a point of interest, in another recently completed traffic study which we did for the South Burlington Factory Outlet Center, the City requested that we analyze the Shelburne Road/Swift Street intersection. These analyses were done using the 1985 HCM methods and resulted in projected levels of service of L.O.S. E during future DIN conditions. This level of service improved to L.O.S. B upon completion of the proposed Shelburne Road modifications associated with the Southern Connector. We understand from the state that construction of these modifications may start late this year and will take two years to complete. During this two year period traffic conditions on Shelburne Road are expected to be horrendous due to detours and new ramp construction. The results of the detailed accident analyses confirmed that many accidents on this portion of Shelburne Road are caused by the numerous driveways/curb cuts which exist. What we were not able to document as well as we had hoped, was the impact of northbound traffic on Shelburne Road turning right onto Swift Street. Existing volumes in the northbound curb lane at Swift Street are significantly greater than average; apparently due to traffic bound for I-89. Again, our recent analyses show that the proposed Shelburne Road/I-89 interchange modifications will correct this problem. Our next step is to redo the intersection capacity analyses using the new 1985 HCM methods and to correlate, if necessary, these results with expanded field delay measurememnts. I expect that we can complete this in the next week or two and wrap this up.

Wheatley, III Vermont Agency of Transportation 133 State Street Montpelier, Vermont 05602 BE: Traffic Impact Evaluation -Shelburne Road Retail Shopping Center U.S. Route 7-South Burlington, Vermont FILE: 85082 Dear Mr. Wheatley: In response your letter of November 8, 1985 concerning the above -referenced traffic impact evaluation, we wish to offer the following: 1. We have revised the estimated 1985 and 1990 design hour volumes. The new estimates were prepared using a 2.5% annual growth rate, compared to a growth rate of 1.9% used in the initial report. In addition, traffic generation by the proposed Project was recalculated using ITE Land Use Code 822, and additional traffic from a proposed 25,000 sq.ft. expansion of the South Burlington Factory Outlet Center included in the analyses. 2-3. Attached are revised intersection capacity analyses for the segment of Shelburne Road between Swift Street and the Project/Laurel Hill Drive intersection. These analyses were performed using four conditions: a) 1990 without Project b) 1990 with Project c) 1990 w/o Project & w/I-189 interchange modifications d) 1990 w/Project & I-189 interchange modifications The latter two conditions apply only to the Shelburne Road/Swift Street intersection. These analyses were performed using the 1985 Highway Capacity Manual methodology, and as a result are much more detailed than the initial analyses. They do, however, confirm that during the design year of 1990, with this Project, Level of Service C traffic conditions can be maintained on Shelburne Road at the K/Mart-Brewer Parkway and Project/Laurel Hill Drive intersections. It is apparent, however, that the present Shelburne Road/Swift Street intersection creates a severe bottleneck for northbound traffic flow on Shelburne Road. This intersection, as it presently exists, is over -capacity and operates at Level of Service E. The resulting traffic congestion affects the two southerly intersections, and operationally reduces their level of service to E also. Design • Inspection a Studies • Permitting Mr. William K. Wheatley, III FILE: 85082 19 March 1986 Page Two ll � This bottleneck was found to be eliminated by the construction of proposed modifications to the I-189 interchange at Shelburne Road. The projected levels of service at the Swift Street intersection improved to Level of Service B, both with and without this Project. At all intersections, 1990 DHV conditions were analyzed using existing signal timings and cycle lengths. It is our understanding all signals from Home Avenue south to Baldwin Avenue will be replaced as part of the I-189 interchange modifications. This new signal system may allow possible further improvements in traffic conditions beyond what we can project at this time. 4. A detailed accident history analysis was performed, as requested. The results indicate that the majority of accidents (particularly rear -end collisions) on this segment of Shelburne Road occur in the northbound direction. It was also noted,that a significant number of accidents are caused by left -turning vehicles exiting from businesses on the east side of Shelburne Road, whose sight distances are obstructed by queued northbound vehicles. Improvements in northbound traffic flow associated with the proposed I-189/Swift Street intersection modifications should significantly reduce existing accident rates. 5. The method of controlling slip ramp traffic (stop vs. yield) can be determined upon the final design of the proposed intersection. 6-8. The revised intersection capacity analyses determined that maintaining Level of Service C on Shelburne Road during the 1990 DHV with this Project will require the following geometric improvements: 1. Construction of the proposed I-189/Swift Street interchange modifications. 2. Adding a separate right turn exit lane on Laurel Hill Drive. Concerning the potential interconnection between this Project and the adjoining K-Mart shopping center to the north, we agree that such an interconnection would be of benefit in reducing traffic volumes on Shelburne Road. We understand from our Client, however, that while he also agrees and hopes to implement this interconnection, he cannot guarantee that the necessary agreement with the owners of the K-Mart can be worked out. FITZPATRICK-LLEWELLYN INCORPORATED Engineering and Planning Services Mr. William K. Wheatley Z FILE:35032 //� _ 19 March 1986 Page Three. ��) An estimate of the potential volumes of vehicular traffic that mould use this interconnection was obtained by measuring the cross -traffic between the Shelburne Road Plaza (Sears) and the South Burlington Factory Outlet Center on two occasions. It was observed that an average of 11% of the traffic entering one came directly from the other. Applying this percentage to this Project and the K-Mart shopping center, results in a reduction in the volume of traffic on Shelburne Road between these two centers during 1990 DHV conditions of up to 115 vehicular trips per hour. We hope the above, and the attached intersection capacity analyses results, adequately addresses the concerns and comments of the Agency of Transportation relative to this Project. Should you have any questions or if we can be of additional assistance, please feel free to contact us.

"Traffic Impact Evaluation - Shelburne Road Retail Shopping Center, South Burlington, Vermont", by FitzPatrick-Llewellyn Incorporated, dated October 1985. 2. Comment letter from Wilson Wheatley, VAOT, to Douglas FitzPatrick, FLI, dated November 8, 1985, concerning the above evaluation. 3. Letter from Roger Dickinson, FLI, to Wilson Wheatley, dated March 19, 1986. 4. An updated site plan for the above -referenced Project. As discussed last Thursday, the above material is being submitted on behalf of our Client, Mr. Ernest Pomerleau, Pomerleau Real Estate Co., P.O. Box 6, Burlington, Vermont 05402. This Project is still in the preliminary stages and has yet to formally apply for local and state approvals. We do, however, believe it is appropriate at this time to request concurrence from the Vermont Agency of Transportation with the results of the traffic impact evaluation, and preliminary approval of the proposed access onto Shelburne Road opposite Laurel Hill Drive. Should you have any questions, or if we can be of further assistance, please feel free to contact us. Sincerely; FITZPATRICK-�LXWELLYN INCORPORATED ,I Rog r Dickinson, P.E.

Burlington, US 7, LS 75+60 LT Proposed Pamerleau Commercial Dev. Dear Mr. Dickinson: We have completed our review of your revised traffic data/ analyses for this project and offer the following comments: In general, the revised 1985 and 1990 design hour volumes appear reasonable as does the revised traffic estimated to be generated by the proposed development. Conceptually, it would appear that with significant geometric/ traffic engineering improvements along US Route 7 at key intersection locations, acceptable levels of service/delays could be achieved with the proposed project. An interconnect road should be constructed between the proposed project and the adjoining K-Mart shopping center to the north. This improvement would provide much needed relief to US Route 7 traffic conditions and should be mutually advantageous to both developers. A separate right -turn exit lane would be required on Laurel Hill Drive. Detailed construction plans for the proposed access, traffic signal installations, and any other required improvements must be submitted to the Agency for review. Sincerely, Wayne/ G .

Burlington, VT 05401 Dear Jane: Per the Planning Commission's request of last fall, we detained the review process of our Shelburne Road land to assess what might be possible for appropriate development on this parcel. It was indicated at that time that by late spring, the Commission inconjunction with the Regional Planning Commission would have had an opportunity to review the overall analysis of development on Route 7. Since the completion of this study is still some- what in the distance, we are presently at a loss as to how to proceed within the prescribed guidelines of the Planning Commission. We, as you realize, have done extensive traffic analysis and engineering review of this area and would greatly appreciate whatever insight you could provide us on timing and what the wishes of the Planning Commission are at this time. I will look forward to your response. Sincerely yours, Ernest A. Pomerleau EAP/nlb Pomerleau Real Estate Co. P. O.

Our report concludes that this Project will not create an undue adverse impact on existing levels of traffic congestion or traffic safety on adjacent streets or at nearby intersections. IAe look forward to presenting the results of this evaluation to local and state officials, at your convenience.

RJD: amo Design 0 Inspection 0 Studies 0 Permitting SUMMARY AND CONCLUSIONS This Report evaluates potential traffic impacts resulting from the construction of a proposed retail shopping center, having a gross floor area of 1b0,000 sq. ft., on the west side of Shelburne Road in South Burlington. The impact of this Project on existing (1985) and future (1990) levels of traffic congestion was evaluated by observing existing traffic flow, and performing detailed intersection capacity analyses at existing and proposed intersections. The results of these analyses indicate that existing geometric deficiencies are a greater factor in causing traffic congestion than future increased traffic volumes. Rith appropriate geometric improvements, the analyses concluded that it will be possible to maintain Level of Service C traffic conditions on Shelburne Road in the immediate vicinity of this Project during 1990 design hour volumes, including Project generated traffic. Traffic safety impacts were assessed by evaluating the number and locations of accidents which occurred during a five-year period (1979-1983). Existing accident rates at major intersections within the study area were found to be above average, with several intersections being classified as "high" accident locations. The vast majority of these accidents appear to be associated with the presence of large numbers of stopping and turning vehicles. Additional traffic generated by this Project is not anticipated to significantly increase existing accident rates. Again, needed geometric and signal improvements would improve traffic safety on Shelburne Road in this area. Potential impacts of the additional traffic generated by this Project will also be mitigated by the installation of a needed traffic signal at the Shelburne Road/Laurel Hill Drive intersection plus the elimination of the existing Burger King curb cut and access directly onto Shelburne Road. Examination of long-range plans to improve traffic flow on this portion of Shelburne Road indicate that the Southern Connector project, as presently planned, incorporates many of the geometric and traffic signal improvements needed to improve existing traffic conditions and to maintain acceptable levels of congestion and safety for the duration of the study period. -1 - INTRODUCTION Pomerleau Real Estate Company is proposing a retail shopping center on a 40 acre parcel located west of Shelburne Road (U.S. Route 7) and south of Queen City Park Road in South Burlington, Vermont. In conjunction with this development, FitzPatrick-Llewellyn Incorporated was engaged to perform a traffic impact evaluation of adjacent streets and intersections. A preliminary site plan of the proposed shopping center is included as Appendix A. This plan shows the proposed construction of a supermarket ( gross floor area of b0, 000 sq. ft. ) and other retail shopping stores ( dry goods - 100,000 sq.ft.). The entire complex is to be an integrated group of commercial establishments which will be developed and managed as a unit. The primary point of access for vehicular traffic will be from Shelburne Road, at a point directly opposite Laurel Hill Drive. A secondary access has also been shown, which if constructed, would connect with the existing shopping center immediately to the north. Two major areas of concern to local and state officials are addressed herein: Traffic Congestion and Traffic Safety. The objective of this Report is to identify potential impacts created by this Project in each of the above areas of concern for both existing and future traffic conditions. For the purpose of this evaluation, the study area was limited to Shelburne Road (U.S. Route 7) between its intersections with Swift Street and Baldwin Avenue. -2- TRAFFIC CONGESTION Serving a major north -south travel corridor on the Kest side of Vermont, Shelburne Road (U.S. Route 7) functions as a primary urban arterial highway. Presently (1985) almost 25,000 vehicles per day travel Shelburne Road in the immediate vicinity of this Project. This volume of traffic is accomodated by two lanes in each direction, separated by a continuous two-way left turn lane. The total roadway width (curb to curb) equals 60 feet. All major intersections are signalized by an interconnected signal system extending from Swift Street south to Baldwin Avenue. Existing (1985) design hour volumes (DHV) within the study area were determined from the following traffic counts: 1. Automatic Traffic Recorder Count, Shelburne Road (between Queen City Park Road and K-Mart), Vermont Agency of Transportation, April 24 - May 1, 1984. 2. Automatic Traffic Recorder Count, Shelburne Road (between Baldwin Avenue and McIntosh Avenue), Vermont Agency of Transportation, April 24 - May 1, 1984. 3. Turning Movement Data - 1983 DHV, Shelburne Road/K-Mart/Brewer Parkway, Vermont Agency of Transportation. 4. Turning Movement Count, Shelburne Road/Laurel Hill Drive, FitzPatrick-Llewellyn Incorporated, August 14, 1985. 5. Turning Movement Count, Shelburne Road/Burger King, Fitzpatrick -Llewellyn Incorporated, October 1, 1985. 6. Turning Movement Count, Shelburne Road/K-Mart, Fitzpatrick -Llewellyn Incorporated, October 1, 1985. Where the data was generated prior to 1985, as in sources (1-3), the volumes were adjusted by applying a growth factor to give 1985 volumes. The appropriate growth factor for this type of highway was selected from data developed by the Vermont Agency of Transportation. As mentioned above, design hour volumes were developed from the above -referenced data. The design hour volume is defined as the 30th highest hourly traffic volume which occurs on an annual basis and is used as a design parameter in the design of highways, intersections and traffic control parameters. Since large projects, such as this one, seldom are completed, fully occupied and operational within a one year period, traffic volumes are typically projected to a future design g year, and conditions also analyzed for that design year. For this Project, a five-year projection, to 1990, was utilized. Once the DHV's and corresponding turning movements of adjacent street traffic were determined, it was necessary to estimate the volumes and directional patterns of the additional vehicular traffic which this Project will generate. -3- Additional traffic, which Rill be generated by this Project, Has estimated using trip generation rates, as outlined in the "ITE Informational Report, Trip Generation, 3rd Edition". This report outlines results of trip generation studies for various land -use categories during "average weekdays" and periods of peak traffic volumes. Land -use category 823, Retail Shopping Center, 200, 000-299, 999 G. S. F. (G. S. F. = gross square feet of leaseable area), was used, because its land -use description most closely matched that of this Project's, and the floor area range matched the total of this Project's floor area plus that of the adjacent existing shopping center. It is relevant to note that three separate major retail shopping centers, having a combined gross floor area of almost 400,000 sq. ft., presently exist within 1/2 mile of this Project. TABLE 1 PROJECTED -VEHICULAR -TRIP -VOLUMES Average Heekday Vehicle Trip Ends 8,096 VPD A. M. Peak Hour (7: 00-8: 00 a. m. ) Entering 64 VPH Exiting 32 VPH TOTAL 96 VPH P.M. Peak Hour (4: 00-5: 00 p. m. ) Entering 372 VPH Exiting 396 VPH TOTAL 768 VPH The above vehicular trip volumes do not take into account the diversion of existing traffic from Route 7 into the Project or existing traffic presently being generated by the Burger King restaurant. Several origin/ destination studies, performed at major shopping centers, have documented that between 25%-40% of traffic entering and exiting a major retail shopping center, such as this one, represents existing trips diverted from adjacent streets. The lower limit of 25% was used in analyzing potential traffic impacts resulting from this Project. As indicated in Table 1, traffic generated by this Project will typically peak on weekdays during the P.M. peak hour, between 4: 00 p.m. and 5: 00 p.m., of adjacent street traffic. The two peak volume conditions, ocurring simultaneously, will therefore result in the greatest amount of traffic congestion. The directional distribution of traffic entering and exiting the Project during the P.M. peak hour was estimated from existing traffic patterns and turning movements at the major retail shopping center (K-Mart) and fast-food restaurant (Burger King) located immediately to the north of this Project. These patterns indicate that the percentages of northbound/through/southbound turning movements will be b5%/2%/33% and -4- 43%/3%/54% for entering and exiting traffic, respectively. Since traffic flow on an urban street network is typically limited by the capacity at intersections, potential impacts of this Project on existing traffic conditions were determined by performing intersection capacity analyses. P.M. peak hour traffic conditions were analyzed in detail at two intersections within the study area; Shelburne Road/Project/Laurel Hill Drive and Shelburne Road/K-Mart/Brewer Parkway. Analyses were performed for both 1985 and 1990 design hour volumes, and both with and ( without this Project. The methodology used was obtained from the "1a85_ fHighxay_Capacity_Manual, Transportation Research Board, Washington, D.C.". Table 2 below presents the results of these analyses. The detailed calculations are also enclosed as Appendices B-E. INTERSECTION Shelburne Rd./K-Mart/ Brewer Parkway TABLE_2 DESIGN-HOUR-LEVELS_OF_SERVICE 1985 1990 WITHOUT WITHOUT PROJECT PROJECT_ L. 0.

F = Extreme delays or failure Urban streets and intersections are generally designed to maintain Level of Service (L. 0. S. ) C to D during DHV conditions. The above levels of service have been defined to represent reasonable ranges in the degree of traffic loading and resulting vehicular delays and average speed on urban streets and intersections. As indicated above, L.O.S. A represents very low volumes with ample reserve capacity and no vehicular delays, whereas L.O.S. F represents a street or intersection at capacity with extremely long queues and vehicular delays resulting. The above level of service projections require that intersections and their connecting roadways be properly designed and free from influence by any external factors which may adversely impact traffic flow. Our observations of existing traffic flow on Shelburne Road, within the study area, indicate that this is not presently the case. Actual existing levels of service are estimated to be one or two ranges lower than those calculated, primarily due to inadequate geometries which significantly slow traffic flow. For southbound traffic flow, there presently appears to be a bottleneck located at the Shelburne Road/Queen City Park Road intersection, due to the proximity of the I-89 exit ramp, and the resulting lack of "weaving" -5- space. "Heaving" is defined as a lane -change maneuver where vehicles must merge into and/or cross another traffic stream. Major conflicts in this area include vehicles desiring to make right turns onto Queen City Park Road, left turns onto Lindenwood Drive and Brewer Parkway, right turns into K-Mart, with other vehicles. The impediment in traffic flow occurs when, as an example, a vehicle exiting the I-189 ramp desires to make a left -turn at Brewer Parkway, and cannot cross the stream of traffic. This vehicle then stops to await an acceptable gap, thereby blocking other vehicles behind it. Northbound traffic flow appears to be impeded by the lack of adequate curb radii for right turning vehicles, particularly at the Swift Street intersection, where a significant percentage of vehicles turn right. Because these vehicles must slow to almost a stop in order to turn, traffic following in the curb lane also must slow, causing queuing to occur from Swift Street south to Baldwin Avenue during peak traffic periods. The much postponed and maligned Southern Connector project includes proposed modifications to the on and off ramps of I-189, the Swift Street intersection and the existing traffic signal system from Home Avenue south to Baldwin Avenue. In addition, Pine Street will be terminated north of the Southern Connector, thereby eliminating the use of Queen City Park Road and, indirectly, the K-Mart Shopping Center as a major through route. Presently, approximately 23-30% of southbound traffic exiting and 45-50% of northbound traffic entering this shopping center to and from Shelburne Road during the P.M. peak hour represents through traffic taking a shortcut. The Southern Connector Project will correct the problems cited above and allow significantly improved traffic flow on Shelburne Road during peak traffic periods. Examination of the calculated intersection levels of service, as outlined in Table 2, indicate that overall traffic flow at the Shelburne Road/Laurel Hill Drive intersection will be significantly improved by the installation of a traffic signal at this location. In addition, it was determined that the existing Shelburne Road/K-Mart/Brewer Parkway intersection will operate at one level of service range lower than the proposed Shelburne Road/Project/Laurel Hill Drive intersection. This difference is caused by the inclusion of a second left -turn lane, in addition to a left-turn/straight lane and a right -turn lane at the proposed Project exit, thereby reducing the sum of critical volumes at that intersection. If a similar modification could be made at the K-Mart access, the projected level of service at that intersection would remain at L.O.S. C during 1990 DHV conditions with this Project. To summarize, maintaining Level of Service C traffic conditions on Shelburne Road during the 1990 DHV upon completion of this Project will W-C i require the following geometric improvements: E 1. Revise the on -off ramps of I-189 as planned by the Southern Connector project. 2. Add a separate northbound right -turn lane and increase the curb radii at the Shelburne Road/Swift Street intersection. This improvement has also been incorporated into the Southern Connector project. I Increase existing curb radii at other intersections and driveways in the immediate vicinity of this Project. I 4. Construct an interconnecting access directly linking this Project with the existing shopping center to the north. 5. Add a second left -turn lane at the west approach.(K-Mart) of the Shelburne Road/K-Mart/Brewer Parkway intersection. Appendix F details the lane layout and conceptual design of the proposed intersection and traffic signal at the new access road to this Project. -7- TRAFFIC SAFETY The safety of vehicular traffic traveling to and from this Project is largely dependent on the geometric and physical conditions of adjacent streets and on the presence of adequate traffic control devices. Existing geometric conditions Rith respect to the horizontal and vertical alignment of Shelburne Road are excellent. Adequate intersection sight distances and stopping sight distances exist throughout the study area. The only geometric deficienceies noted are the inadequate curb radii at driveways and intersections previously discussed. A five year (1979-1983) accident history of Shelburne Road in the immediate vicinity of this Project Ras obtained from the Vermont Agency of Transportation. These records provide detailed information concerning the precise location, date, time, weather, cause, type, and the number of injuries and/or fatalities of each accident. During the five-year period, 312 accidents occured between McIntosh Avenue and the I-189 eastbound on -ramp. Of these, 24b occured at intersections (+/-150 feet). Since a large majority of accidents occured at intersections, average and critical accident rates for each intersection were calculated based on the total number of intersections involved and the total number of intersection -related accidents. The average accident rate, based on state -Ride data, for a FAP urban intersection, equals 0.571 accidents per million vehicles. The critical accident rate, calculated from this average accident rate and the volume of traffic, Ras determined to be 0.738 accidents per million vehicles, which is equivalent to 38 accidents occuring at an intersection on this portion of Shelburne Road during a five-year period. If the actual accident rate exceeds the critical accident rate, then it can be reasonably concluded that statistically, the highway segment or intersection is a "high" accident location. The actual number of accidents which occured at each intersection during the five year period is given by Table 3, below. TABLE-3 FIVE-YEAR -ACCIDENT -HISTORY -AT -SHELBURNE -ROAD -INTERSECTIONS ---------------------------------------------------- NUMBER OF NUMBER OF NUMBER OF INTERSECTION ACCIDENTS INJURIES FATALITIES Swift Street 47 22 0 Queen City Park Road 53 23 0 Lindenwood Drive 21 6 0 K-Mart/Brewer Parkway 45 13 0 Laurel Hill Drive 33 7 0 Hough Street (closed 1985) 7 4 0 Baldwin Avenue 21 13 0 McIntosh Avenue 19 9 0 W-10 i The above accident information indicates that the Swift Street Queen City Park Road, and K-Mart/Brewer Parkway intersections appear to be "high" accident locations. The primary causes of accidents at these locations include rear end collisions and collisions involving turning movements. The close proximity of signal systems in this area, inadequate curb radii and numerous driveways are all contributing factors to this above average accident rate. Possible improvements, to reduce this accident rate, include better synchronization of signals, increasing curb radii at driveways and intersections, and closing existing curb cuts where possible.

Dear Mr. Dickinson: We have completed our review of your revised traffic data/ analyses for this project and offer the following co:mients: In general, the revised 1985 and 1990 design hour volumes appear reasonable as does the revised traffic estimated to be generated by the proposed development. Conceptually, it would appear that with significant geometric/ traffic engineering improvements along US Route 7 at key intersection locations, acceptable levels of service/delays could be achieved with the proposed project. An interconnect road should be constructed between the proposed project and the adjoining K-Mart shopping center to the north. This improvement would provide much needed relief to US Route 7 traffic conditions and should be mutually advantageous to both developers. A separate right -turn exit lane would be required on Laurel Hill Drive. Detailed construction plans for the proposed access, traffic signal installations, and any other required improvements must be submitted to the Agency for review. Sincerely, Z� 71" Wayne! G .

As you can see, we have not reviewed any plans yet and, in fact, have formally requested Ernie Pomerleau to wait until our computerized traffic impact model is available to evaluate the full traffic impact of this development. Mr. Pomerleau has agreed to postpone his application until the Commission is ready. Clearly, one of our major concerns is the traffic impact. We have developed an ad hoc committee to study the Shelburne Road corridor problems and would like a representative from the City of Burlington to sit on that committee. Perhaps Mark Eldridge or a member of the Burlington Planning Commission would be interested. I will send a letter regarding this soon. Next week, the Planning Commission will be reviewing a proposed agenda for a meeting with the Burlington officials. I am hopeful that a dialogue between our two cities will bring issues of common interest and conflict out into the open. My Planning Commission has requested that the members of the Burlington Planning Commission attend any joint meeting we hold. I will be working with Brenda Torpy to discuss the agenda and possible dates soon. I will keep you posted on future Commission meetings regarding these Shelburne Road developments.

Many officials commented that our response was untimely and suggested that Burlington should have objected long ago. I continue to be of the opinion that the Act 250 hearings are the forum to discuss the regional impact of major development projects. On the other hand, I am sincerely interested in enhancing communications with South Burlington officials. It is in this spirit that I am, at this very early stage, expressing my interest in development proposed on Shelburne Road by Messrs. Pomerleau and Milot. I recently read in That Paper that Tony Pomerleau had begun discussions concerning 160,000 square feet of retail space on property on Shelburne Road. I also understand that Gerald Milot is contemplating a similarly sized development to the south of this site. Clearly, projects of this size will have a regional impact. I would appreciate it if you would advise me of the status of deliberation concerning these projects. 1 would also appreciate it if you would send me copies of agendas and minutes of Planning Commission hearings at which time these projects are discussed.

We obviously would prefer to have a quicker response but in keeping with our efforts to maintain a very cooperative interaction with your department and the community, we will abide by the wishes of the commission, and wait the several months for your review process to be finalized.

Box 6 Burlinqton, Vermont 05401 Dear Mr. Pomerleau: The Planning Commission met on Tuesday, November 19 to discuss the City's traffic standards and the Shelburne Road Corridor study that is being undertaken by the Metropolitan Planning Organization (MPO). It was their unanimous decision to request that you postpone your application for Sketch Plan review until a data base can be developed for Shelburne Road. From this data base, we will plug in the expected traffic projections and directional distribution of a development to analyze the impact on selected intersections. This process is ex- pected to take four to five months. I£ this request is unacceptable to you, the Planning Commission, of course, must hear your application. However, it will hire its own independent consultant to evaluate your study and conduct any independent traffic analysis. We would expect you to reimburse the city for the cost of this analysis regardless of the outcome. Please be aware of Section 11.504a of. the Zoning Regulations which allows the Planning Commission members to designate any intersections that they feel may be affected by a proposed development. It is the Commission's opinion that the present traffic problem is so serious and the impact of a large develop- ment on Shelburne Road may be so great that we would require proof that your development has no adverse impact on inter- sections that are already below level C and will not cause any intersection to fall below level C. Finally, the Commission has requested that you disclose all phases of your plan including any development that you would propose after construction of the so-called South Burlington Connector. While the plan will be evaluated on your present proposal the Commission feels it can only make informed and Ernest Pomerleau November 22, 1985 Page 2 intelligent decisions if it knows the complete story. Please call me at your convenience if you wish to discuss this further. Sincerely, Jane B.

Pomerleau Pomerleau Real Estate P.O. Box 6 69 College Street Burlington, Vermont 05401 Dear Mr. Pomerleau: ZONING ADMINISTRATOR 658-7958 Mary -Barbara Maher asked me to respond to your letter of October 7, 1985 in which you requested our response to your proposal for 160,000 square feet of retail space on Shelburne Road. While we can not claim to represent the entire seven member Commission, the following suggestions may be helpful in your planning process. Clearly, our primary concern is the serious traffic problem on Shelburne Road and our desire to not aggravate it. In fact, any development would be expected to improve the traffic flow. 1) Access to Queen City Park Road is essential. While we under- stand much of this land is rough terrain, it nonetheless would be a critical feature to lessen the Shelburne Load traffic impact. It also would begin to lay the ground work for a South Burlington Southern Connector. 2) We will request a dedication of the land for the proposed Southern Connector. 3) At a minimum we would expect one access opposite Laurel Hill Drive with the Burger King access relocated to that internal location, one access to the Milot-Fayette property and one access to the Just -Gold K-Mart property. The need for right turn southbound lanes and traffic signals must also be investigated. 4) The northbound bottleneck at Swift Street must be resolved. This seems to require acqu i s i t ion of- add i t i.onl--I:I r i(Ili t-of-way for a right -turn lane. 5) We prefer to see n innovative larking clleme that is visuall',' attractive from Shelb e Road. 1✓ti7e recommend that parking be placed at the rear and sides f the huildinq(s) and not in front. The Ernest A. Pomerleau October 18, 1985 Page 2 front should be landscaped, and perhaps have pedestrian/shopper amenties. 6) Finally, you can expect that the Planning Commission will hire its own traffic consultant from outside the Greater Burlington area to generate independent recommendations and analyses. We understand your concern about being proceeding since adjacent projects are not yet ready to come before the Commission. At the smae time, we recognize that while your project alone may require certain traffic, intersection or geometry improvements,(the bandaid approach),the two projects together may require an even greater solution such as the Southern Connector. With this in mind, you should not be surprised if new developments on Shelburne Road are required to contribute substantially to this project. I will gladly discuss any of these items with you further. Please call me at your convenience. Sincerely, J, L/ Jane B.

Box 6 Burlington, Vermont 05402 Dear Mr. Pomerleau, P.O. Box 333 Winooski, Vermont 05404 (802) 655-3661 November 7, 1985 As you are aware, I have been involved in the planning of your Shelburne Road project for over two years. During that time period I became a representative (from Winooski) on the Metropolitan Planning Organization (MPO) and later became chairman of that body. Recently, the northern portion of Shelburne Road in South Burlington has become one of the MPO's highest priorities, and a study has been ini- tiated to consider transportation improvements for that area. The extent of improvements will be affected both by existing traffic and by new traffic from your development and several other large projects. So as to actively and objectively participate in the MPO's efforts on Shelburne Road, I find that I can no longer provide consulting services for your project. I offer that decision with reluctance, because I support this development and feel that there are few more suitable locations in Chittenden County for major commercial uses. Several parting observations on the traffic impact evaluation prepared by Fitzpatrick -Llewellyn and on the recent correspondence between you and the City of South Burlington are offered on the following page. I hope that the Vermont Agency of Transportation, the Metropolitan Planning Organization, the City of South Burlington, existing property owners and developers of new projects will be able to work together to provide the needed improvements for Shelburne Road. Sincerely, lea' David H. Spitz cc: Jane Bechtel LaFleur South Burlington Planning Commission Fitzpatrick -Llewellyn Inc. 11/7/85 D.H.S. Comments on Shelburne Road Traffic Studies 1) It is appropriate to consider both short-range and long-range improve- ments for the Shelburne Road corridor. Size and phasing of new development can be tied to the implementation of such improvements. 2) Specific improvements have already been recommended in the (Burlington) Southern Connector plans, the South Burlington Connector Environmental Impact Statement and in the Fitzpatrick -Llewellyn "Traffic Impact Evaluation, Shelburne Road Retail Shopping Center" (page 7). All of these sources provide relevant input and should be considered. 3) The long-range aspect of the study should at least consider the following: a) The length of a potential Shelburne Road bypass, pre- sumably starting at the Southern Connector/I-189 inter- section and ending at a point to be determined by existing and projected land uses and traffic volumes. The point of intersection with Shelburne Road is a critical point to be determined at an early date. b) The width of the study area, preferably limited to the area between the railroad tracks and Shelburne Road. Any "Super-7" corridor to the east is too grandiose to be included in the current study. c) Design elements of the bypass, particularly number of lanes and use of at -grade intersections versus separated crossings. d) Whether transportation systems management or other tech- niques could actually preclude the need for a bypass, with any improvements provided only along the existing Shelburne Road corridor. My own estimate is that a bypass is necessary at least for the upper portion of Shelburne Road in South Burlington. 4) In the short-range, it is clear that some specific improvements can upgrade current levels of service on Shelburne Road. The benefit to be provided from such improvements and the extent of new development that could be accomodated can be evaluated in advance of a complete long-range study. Particular attention should be given to widening of the Swift Street curb radii and/or adding an extra approach lane to ,Swift Street and I-189. However, I am very skeptical about the benefit from a short term connection to Queen City Park Road. If such a connection is pro- vided, the great majority of traffic would still flow back to the busiest 11/7/85 page 2 D.H.S. portion of Shelburne Road. The long-term connection should be to the Southern Connector/I-189 corridor, and a Queen City Park Road connector would be an expensive, short-term solution. 5) The studies should be undertaken under the control of the City and/or MPO with consulting assistance, as needed, and using available data and general support from the Vermont Agency of Transportation. Local developers have offered to contribute financially to the Shelburne Road studies in order to facilitate their implementation, particularly short-term evaluations of whether some level of development can be accomodated by immediate Shelburne Road improvements. POMERLEAU November 5, 1985 Jane LaFleur City Planner 575 Dorset Street So. Burlington, VT 05401 Dear Jane: I wish to thank you for the time extended to David and I recently to discuss our proposed Route 7 project. As a followup to that meeting, I thought it important to review several of the outstanding issues. 1) As discussed, we still have reservations as to the effectiveness and economic viability of putting in a simple service road to Queen City Park road. We feel that the energy and time would be better expended on resolving the South Burlington connector issue. I would hope that we would some how be able to phase our portion of the project in such a manner that would permit a limited amount of construction to take place with the remaining amount subject to major access improvements. Such an approach, I feel, would act as a very strong catalyst for adjacent property owners and other developers to participate in a mutually beneficial solution. Our feeling is that a simple access road to Queen City Park would not assist any of the traffic movement initially and knowing the State's engineering approaches to new highways, may find no particularly advantageous cost savings in a road initially constructed by the developers. More importantly the vast sums of dollars such an initial road would cost in our perception would be much better expended leveraging the City's portion of the eventual connector rather than going to a road which would be obsolete. 2) With regard to the dedication of land for proposed southern connector, rather than a pure dedication, it might be beneficial to leverage these parcels once again against the City's share of the connector. 3) As indicated in the recently submitted traffic survey with the attached plot plan, the intersection after State review, is a fairly sophisticated one which incorporates as suggested, the Laurel Hill Drive connection and the elimination of a curb cut for Burger King onto route 7, in exchange for one on the new entrance area. We have also expended a great deal of energy in attempting to come up with a variety of designs that interacts appropriately with our adjacent property owner's as well. Pomerleau Real Estate Co. P. O. Box 6, 69 College Street Burlington, Vermont 05402 802/ 863-2841 Jane LaFleur Page II 4) With regard to Swift Street, we have received indications from the State that they are proceeding with a right hand turn lane improvement to this area in the near future. As mentioned, we will attempt to get confirmation on this issue. 5) With respect to parking, I am convinced that we can address the primary concerns of minimizing black top and maximizing berms, landscaping, lighting, in such a manner as to minimize the adverse impact to the aesthetics that parking areas create. As discussed, parking in the rear of a retail facility marks economic disaster and from personal experience with very few exceptions has never worked effectively. I am convinced that this issue can be worked out in such a manner as to address the planner's concerns. 6) We have submitted a traffic survey to you for your review and evaluation, as requested by the Planning Commission in our initial meeting last year. Hopefully, it will at least give a benchmark from which to work since it indicates that we should be able to construct a reasonable amount of retail space without the intersection dropping below a level C. You indicated that it would be mandatory at this point to have the City contract another outside traffic engineer to not only review these figures but to do an entire analysis of the route 7 area as it pertains to our land and the adjacent Fayette/Milot plot. Obviously, without this study we cannot proceed and if no funds are available from the City, we as well as I am certain the Milot people, would be happy to participate in some reasonable manner to expedite this analysis. 7) Additionally, as further discussed, we have contracted with Milot Real Estate a site planner to review the interactions of our two parcels to better illustrate to the Planning Commission an effort to appropriately interface these parcels. 8) We still feel it is important for us to proceed independently although as indicated above, are doing everything possible to assure the City that there will be a proper interaction with adjacent property owners in an effort to provide a well planned sophisticated environment. Since we are anxious to get further clarification as to how we might best proceed, we would be happy to provide whatever additional information you may request. Thank you for your time and consideration. I will look forward to your response. Sincerely yours, Ernest A. Pomerleau EAP/nlb POMERLFAU October 7, 1985 Mary -Barbara Maher 66 Hinesburg Road So. Burlington, VT 05401 Dear Mary -Barbara: As an update to the status of our land on Shelburne Road, I thought it appropriate to write outlining where we are for you and request some insight into our best approach with the Planning Commission prior to our• next preliminary meeting with the Board. We have met with Jane Bechtel Lafleur and Dick Ward who have been very helpful in assisting us to focus on several issues. After this meeting and others with Jerry Milot, we have been restructuring our proposed project to better interact with any future plans on the adjacent property. Essentially, the following is a synopsis of our situation and our questions on how to proceed. 1) We have completed an indepth traffic study with respect to our project as requested illustrating that with appropriate improvements and design, an additional 160,000 sq.ft. of retail space could be constructed. Hov., do vie coordinate this re-ort with the Commission to evaluate the status of this traffic analysis? 2) We have been working for some time on this latest phase of development and have dramatically scaled it down to accommodate traffic, sewage, and topographical concerns. In light of the timing of the adjacent property, we would inquire if it were possible to maintain reasonable autonomy between projects while still being very sensitive and flexible as to the interaction of the two parcels? 3) We withdrew our recent request to visit with the Board for an update to allow ourselves an additional opportunity to better assess the adjacent property plans and to gain other pertinent data. We would greatly appreciate any insight into the Board's philosophy on this area's development to better address our approach on this project if possible. As we both realize any development on Shelburne Road is a very sensitive topic but we have a unique opportunity to deal --with larger parcels,,and while Pomerleau Real Estate Co. P. O. Box 6, 69 College Street Burlington, Vermont 05402 802/ 863-2841 Mary -Barbara Maher Page II providing many challenges, I am convinced can be developed in a manner to be of benefit to the community of South Burlington.

While we can not claim to represent the entire seven member Commission, the following suggestions may be helpful in your planning process. Clearly, our primary concern is the serious traffic problem on Shelburne Road and our desire to not aggravate it. In fact, any development would be expected to improve the traffic flow. 1) Access to Queen City Park Road is essential. While we under- stand much of this land is rough terrain, it nonetheless would be a critical feature to lessen the Shelburne I:oad traffic impact. It also would begin to 'lay the ground work fol a South BUrlingtc�n Southern Connector. 2) We will request a dedication of the land for the proposed Southern Connector. 3) At a minimum we would expect one access opposite Laurel. hill Drive with the Burger King access relocated to that internal location, one access to the Milot- Fayette prop Lty and onr access; to the Just -Gold K-Mart property. The need for right turn southbound lanes inrd traf f is signals must also be investigated. 4) The northbound bottleneck at Swift Street must 1>r resolved.

We understand your concern about being proceeding since adjacent projects are not yet ready to come before the Commission. At the smae time, we recognize that while your project alone may require certain traffic, intersection or geometry improvements,(the bandaid approach),the two projects together may require an even greater solution such as the Southern Connector. With this in mind, you should not be surprised if new developments on Shelburne Road are required to contribute substantially to this project. I will gladly discuss any of these items with you further. Please call me at your convenience. Sincerely, Jane B.

The impact of this Project on existing (1985) and future (1990) levels of traffic congestion was evaluated by observing existing traffic flow, and performing detailed intersection capacity analyses at existing and proposed intersections. The results of these analyses indicate that existing geometric deficiencies are a greater factor in causing traffic congestion than future increased traffic volumes. Rith appropriate geometric improvements, the analyses concluded that it will be possible to maintain Level of Service C traffic conditions on Shelburne Road in the immediate vicinity of this Project during 1990 design hour volumes, including Project generated traffic. Traffic safety impacts Here assessed by evaluating the number and locations of accidents which occurred during a five-year period (1979-1983). Existing accident rates at major intersections Rithin the study area Here found to be above average, Rith several intersections being classified as "high" accident locations. The vast majority of these accidents appear to be associated with the presence of large numbers of stopping and turning vehicles. Additional volumes of traffic generated by this Project is not anticipated to significantly increase existing accident rates. Again, needed geometric and signal improvements Rould improve traffic safety on Shelburne Road in this area. Potential impacts of the additional traffic generated by this Project will also be mitigated by the installation of a needed traffic signal at the Shelburne Road/Laurel Rill Drive intersection plus the elimination of the existing Burger Ring curb cut and access directly onto Shelburne Road. Examination of long-range plans to improve traffic flow on this portion of Shelburne Road indicate that the Southern Connector project, as presently planned, incorporates many of the geometric and traffic signal improvements needed to improve existing traffic conditions and to maintain acceptable levels of congestion and safety for the duration of the study period. -1- INTNODQCTION Pomerleau Real Estate Company is proposing a retail shopping center on a 40 acre parcel located Rest of Shelburne Road (U.S. Route 7) and south of Queen City Park Road in South Burlington, Vermont. In conjunction with this development, FitzPatrick-LleRellyn Incorporated was engaged to perform a traffic impact evaluation of adjacent streets and intersections. A preliminary site plan of the proposed shopping center is included as Appendix A. This plan shows the proposed construction of a supermarket (gross floor area of 60,000 sq. ft.) and other retail shopping stores (dry goods - 100,000 sq.ft.). The entire complex is to be an integrated group of commercial establishments which mill be developed and managed as a unit. The primary point of access for vehicular traffic Rill be from Shelburne Road, at a point directly opposite Laurel Hill Drive. A secondary access has also been shown, which if constructed, would connect with the existing shopping center immediately to the north. Two major areas of concern to local and state officials are addressed herein: Traffic Congestion and Traffic Safety. The objective of this Report is to identify potential impacts created by this Project in each of the above areas of concern for both existing and future traffic conditions. For the purpose of this evaluation, the study area Has limited to Shelburne Road (U.S. Route 7) between its intersections Rith Smift Street and Baldwin Avenue. -2- TRAFFIC -CONGESTION Serving a major north -south travel corridor on the Hest side of Vermont, Shelburne Road (U.S. Route 7) functions as a primary urban arterial highway. Presently (1985) almost 25,000 vehicles per day travel Shelburne Road in the immediate vicinity of this Project. This volume of traffic is accomodated by two lanes in each direction, separated by a continuous two-way left turn lane. The total roadway width (curb to curb) equals 60 feet. All major intersections are signalized by an interconnected signal system extending from Swift Street south to Baldwin Avenue. Existing (1985) design hour volumes (DHV) within the study area were determined from the following traffic counts: 1. Automatic Traffic Recorder Count, Shelburne Road (between Queen City Park Road and K-Mart), Vermont Agency of Transportation, April 24 - May 1, 1984. 2. Automatic Traffic Recorder Count, Shelburne Road (between Baldwin Avenue and McIntosh Avenue), Vermont Agency of Transportation, April 24 - May 1, 1984. 3. Turning Movement Data - 1983 DHV, Shelburne Road/K-Mart/Brewer Parkway, Vermont Agency of Transportation. 4. Turning Movement Count, Shelburne Road/Laurel Hill Drive, FitzPatrick-Llewellyn Incorporated, August 14, 1985. 5. Turning Movement Count, Shelburne Road/Burger King, Fitzpatrick -Llewellyn Incorporated, October 1, 1985. 6. Turning Movement Count, Shelburne Road/K-Mart, FitzPatrick-Llewellyn Incorporated, October 1, 1985. Ahere the data was generated prior to 1985, as in sources (1-3), the volumes were adjusted by applying a growth factor to give 1985 volumes. The appropriate growth factor for this type of highway was selected from data developed by the Vermont Agency of Transportation. As mentioned above, design hour volumes were developed from the above -referenced data. The design hour volume is defined as the 30th highest hourly traffic volume which occurs on an annual basis and is used as a design parameter in the design of highways, intersections and traffic control parameters. Since large projects, such as this one, seldom are completed, fully occupied and operational within a one year period, traffic volumes are typically projected to a future design year, and conditions also analyzed for that design year. For this Project, a five-year projection, to 1990, was utilized. Once the DHV's and corresponding turning movements of adjacent street traffic Here determined, it Has necessary to estimate the volumes and directional patterns of the additional vehicular traffic which this Project Hill generate. -3- The volume of additional traffic which Rill be generated by this Project was estimated using trip generation rates, as outlined in the "ITE Informational Report, Trip Generation, 3rd Edition". This report outlines results of trip generation studies for various land -use categories during "average weekdays" and periods of peak traffic volumes. Land use category 823, Retail Shopping Center, 200, 000-299, 999 G. S. F. (G. S. F. = gross square feet of leaseable area), was used, because its land use description most closely matched that of this Projects, and the floor area range matched the total of this Project's floor area plus that of the adjacent existing shopping center. (It should be noted that three separate major retail shopping centers, having a combined gross floor area of almost 400,000 sq. ft., presently exist within 1/2 mile of this Project). TABLE 1 PROJECTED -VEHICULAR -TRIP -VOLUMES Average Heekday Vehicle Trip Ends 8,096 VPD A. M. Peak Hour (7: 00-8: 00 a. m. ) Entering 64 VPH Exiting 32 VPH TOTAL 96 VPH P. M. Peak Hour ( 4: 00-5: 00 P. m. ) Entering 372 VPH Exiting 396 VPH TOTAL 768 VPH The above vehicular trip volumes do not take into account the diversion of existing traffic from Route 7 into the Project or existing traffic presently being generated by the Burger Ring restaurant. Various traffic studies have documented that between 25%-40% of traffic entering and exiting a major retail shopping center, such as this one, represents existing trips diverted from adjacent streets. The lower limit of 25% reduction was used in analyzing potential traffic impacts resulting from this Project. As indicated in Table 1, traffic generated by this Project will typically peak on weekdays during the P.M. peak hour, between 4: 00 p.m. and 5: 00 p.m., of adjacent street traffic. The two peak volume conditions, ocurring simultaneously, will therefore result in the greatest amount of traffic congestion. The directional distribution of traffic entering and exiting the Project during the P. M. peak hour was estimated from existing traffic patterns and turning movements at the major retail shopping center (K-Mart) and fast-food restaurant ( Burger Ring) located immediately to the north of this Project. These patterns indicate that the percentages of northbound/through/southbound turning movements will be 65%/2%/33% and 43%/3%/54% for entering and exiting traffic, respectively. -4- Since traffic flow on an urban street network is typically limited by the capacity at intersections, potential impacts of this Project on existing traffic conditions Here determined by performing intersection capacity analyses. P.M. peak hour traffic conditions Here analyzed in detail at two intersections within the study area; Shelburne Road/Project/Laurel Hill Drive and Shelburne Road/K-Mart/Brewer Parkway. Analyses were performed for both 1985 and 1990 design hour volumes, and both with and without this Project. The methodology used was obtained from the "1485_ HighHay_Capacity_Manual, Transportation Research Board, Washington, D.C.". Table 2 below presents the results of these analyses.

E = Very long delays L. O. S. C = Average delays L. 0. S. F = Extreme delays or failure Urban streets and intersections are generally designed to maintain Level of Service (L. 0. S. ) C to D during DHV conditions. The above levels of service have been defined to represent reasonable ranges in the degree of traffic loading and resulting vehicular delays and average speed on urban streets and intersections. As indicated above, L.O.S. A represents very low volumes Kith ample reserve capacity and no vehicular delays, whereas L.O.S. F represents a street or intersection at capacity Kith extremely long queues and vehicular delays resulting. The above level of service projections require that intersections and their connecting roadways be properly designed and free from influence by any external factors, which may adversely impact traffic flow. Our observations of existing traffic flow on Shelburne Road, within the study area, indicate that this is not presently the case. Actual existing levels of service are estimated to be one or two ranges lower than those calculated, primarily due to inadequate geometrics which significantly slow traffic flow. For south bound traffic flow, there presently appears to be a bottleneck located at the Shelburne Road/Queen City Park Road intersection, due to the proximity of the I-89 exit ramp, and the resulting lack of "Heaving" space. "Weaving" is defined as a lane -change maneuver where vehicles must -5- merge into and/or cross another traffic stream. Major conflicts in this area include vehicles desiring to make right turns onto Queen City Park Road, left turns onto Lindenwood Drive and Bremer Parkway, right turns into R-Mart, with other vehicles. The impediment in traffic flow occurs when, as an example, a vehicle exiting the I-189 ramp desires to make a left -turn at Brewer Parkway, and cannot cross the stream of traffic. This vehicle then stops to await an acceptable gap, thereby blocking other vehicles behind it. Northbound traffic flow appears to be impeded by the lack of adequate curb radii for right turning vehicles, particularly at the Swift Street intersection, where a significant percentage of vehicles turn right. Because these vehicles must slow to almost a stop in order to turn, traffic following in the curb lane also must slow, causing queuing to occur from Swift Street south to Baldwin Avenue during peak traffic periods. The much postponed and maligned Southern Connector project includes proposed modifications to the on and off ramps of I-189, the Swift Street intersection and the existing traffic signal system from Home Avenue south to Baldwin Avenue. In addition, Pine Street will be terminated north of the Southern Connector, thereby eliminating the use of Queen City Park Road and, indirectly, the K-Mart Shopping Center as a major through route. Presently, approximately 23-30% of southbound traffic exiting and 45-50% of northbound traffic entering this shopping center to and from Shelburne Road during the P.N. peak hour represents through traffic taking a shortcut. The Southern Connector Project Hill correct the problems cited above and allow significantly improved traffic flow on Shelburne Road during peak traffic periods. Examination of the calculated intersection levels of service, as outlined in Table 2, indicate that overall traffic flow at the Shelburne Road/Laurel Hill Drive intersection Hill be significantly improved by the installation of a traffic signal at this location. In addition, it was determined that the existing Shelburne Road/K-Mart/Brewer Parkway intersection Hill operate at one level of service range lower than the proposed Shelburne Road/Project/Laurel Hill Drive intersection. This difference is caused by the inclusion of a second left -turn lane, in addition to a left-turn/straight lane and a right -turn lane at the proposed Project exit, thereby reducing the sum of critical volumes at that intersection. If a similar modification could be made at the R-Mart access, the projected level of service at that intersection would remain at L.O.S. C during 1990 DHV conditions with this Project. To summarize, maintaining Level of Service C traffic conditions on Shelburne Road during the 1990 DHV upon completion of this Project will -b- require the following geometric improvements: 1. Revise the on -off ramps of I-189 as planned by the Southern Connector project. 2. Add a separate northbound right -turn lane and increase the curb radii at the Shelburne Road/Swift Street intersection. This improvement has also been incorporated into the Southern Connector project. 3. Increase existing curb radii at other intersections and driveways in the immediate vicinity of this Project. y. Construct an interconnecting access directly linking this Project with the existing shopping center to the north. 5. Add a second left -turn lane at the west approach (K-Mart) of the Shelburne Road/K-Mart/Brewer Parkway intersection. Appendix B details the lane layout and conceptual design of the proposed intersection and traffic signal at the new access road to this Project. WAI TRAFFIC -SAFETY The safety of vehicular traffic traveling to and from this Project is largely dependent on the geometric and physical conditions of adjacent streets and on the presence of adequate traffic control devices. Existing geometric conditions with respect to the horizontal and vertical alignment of Shelburne Road are excellent. Adequate intersection sight distances and stopping sight distances exist throughout the study area. The only geometric deficienceies noted are the inadequate curb radii at driveways and intersections previously discussed. A five year (1979-1983) accident history of Shelburne Road in the immediate vicinity of this Project was obtained from the Vermont Agency of Transportation. These records provide detailed information concerning the precise location, date, time, weather, cause, type, and the number of injuries and/or fatalities of each accident. During the five-year period, 312 accidents occured between McIntosh Avenue and the I-189 eastbound on -ramp. Of these, 246 occured at intersections (+/-150 feet). Since a large majority of accidents occured at intersections, average and critical accident rates for each intersection were calculated based on the total number of intersections involved and the total number of intersection -related accidents. The average accident rate, based on state-wide data, for a FAP urban intersection, equals 0.571 accidents per million vehicles. The critical accident rate, calculated from this average accident rate and the volume of traffic, was determined to be 0.738 accidents per million vehicles, which is equivalent to 38 accidents occuring at an intersection on this portion of Shelburne Road during a five-year period. If the actual accident rate exceeds the critical accident rate, then it can be reasonably concluded that statistically, the highway segment or intersection is a "high" accident location. The actual number of accidents which occured at each intersection during the five year period is given by Table 3, below. TABLE-3 FIVE-YEAR-ACCIDENT-HISTORY-AT-SHELBURNE-ROAD-INTERSECTIONS NUMBER OF NUMBER OF NUMBER OF INTERSECTION ACCIDENTS INJURIES FATALITIES Swift Street 47 22 0 Queen City Park Road 53 23 0 Lindenwood Drive 21 6 0 K-Mart/Brewer Parkway 45 13 0 Laurel Hill Drive 33 7 0 Hough Street (closed 1985) 7 4 0 Baldwin Avenue 21 13 0 McIntosh Avenue 19 9 0 -8- The above accident information indicates that the Swift Street, Queen City Park Road, and K-Mart/Brewer Parkway intersections appear to be "high" accident locations. The primary causes of accidents at these locations include rear end collisions and collisions involving turning movements. The close proximity of signal systems in this area, inadequate curb radii and numerous driveways are all contributing factors to this above average accident rate. Possible improvements, to reduce.this accident rate, include better synchronization of signals, increasing curb radii at driveways and intersections, and closing curb cuts where possible. -9- Ira:, It �� [INA Iff-1 MEMO To: Jane Bechtel Lafleur From: Ernest A.
