Summary Purpose of Report & Study Objectives This report summarizes the results of a traffic impact study update conducted by E5 Engineering, PLLC for the proposed Buffalo Run development in Bozeman, Gallatin County, Montana. The objectives of the traffic study are as follows: ▪ Determine the existing vehicular, pedestrian, bicycle, and transit conditions in the study area to establish a base condition. ▪ Assess the impact that the proposed development will have on transportation conditions in the area. ▪ Determine any street, access, bicycle, and pedestrian modifications and/or improvements that will be necessary to effectively accommodate and mitigate future conditions. Study Area The proposed development is located on the site of an existing residence with an outbuilding that includes some limited agricultural use on the north half of the southwest quarter of the southwest quarter of Section 23, Township 2 South, Range 5 East, Principal Meridian of Montana (N ½ SW ¼ SW ¼ of Sec. 23, T2S, R5E, P.M.M.). The project is bounded by Fowler Lane to the west, Meadow Creek Subdivision park land to the east, agricultural land to the north, and mixed residential-agricultural land use to the south. The area offers a mixture of moderate density residential uses and agricultural lands. Vehicle volumes were estimated for the weekday morning and evening peak periods at two existing intersections in the vicinity of the site. The intersections evaluated included the following: ▪ Fowler Lane & Blackwood Road and ▪ South 27th Avenue & Kurk Drive. Alternate Modes of Transportation Pedestrians & Bicyclists Sidewalks are available for pedestrians within the study area on Kurk Drive to the east of the proposed Buffalo Run development as well as throughout the Meadow Creek Subdivision. Other than those included on the fully completed segment of South 27th Avenue between Blackwood Road and Kurk Drive, no dedicated bicycle facilities are currently included within the study area. No pedestrian or bicyclist facilities are currently provided on Fowler Lane. Transit Streamline transit service does not currently have any routes that provide direct service within the study area. 2 Traffic Impact Study Update – Buffalo Run October 2021 Proposed Development The proposed development of Buffalo Run evaluated as a part of this study is to include 180 multifamily units, 29 rowhouses, and 28 duplex units for a total of 237 proposed residential dwelling units. The development will also include a community center for use by the residents within Buffalo Run as well as their invited guests. Primary access to the development is proposed via Kurk Drive that would include an extension from the west boundary of Meadow Creek Subdivision (west of South 30th Avenue) westerly to Fowler Lane. The proposed project is estimated to generate 1,200 average weekday vehicular trips as well as 92 and 101 vehicular trips during the weekday, AM and PM peak hours at full build-out. Pedestrian and/or bicyclist related trips were also estimated at 13 and 15 trips during the weekday, AM and PM peak hours at full build-out, respectively. It is anticipated that the proposed Buffalo Run development will occur over the next five-year period with full build-out and occupancy projected by the fall of 2026. Traffic Operations COVID-19 Effects on Availability of Count Data Due to the coronavirus disease 2019 (COVID-19) pandemic, reliable counts of existing traffic volumes within the study area were not able to be obtained at the time of initial study preparation for the proposed Buffalo Run development. Estimated Traffic Volumes Traffic volume estimations for the study area intersections were developed through vehicle trip generation projections and evaluation of previous modeling. The total estimated traffic volumes for the existing intersection of Fowler Lane and Blackwood Road were developed from modeling completed as part of the Transportation Planning Study for South 27th Avenue & the Montana State University Innovation Campus prepared by Morrison-Maierle in June 2014 and the application of estimated average annual growth rate (AAGR) percentages of fourteen percent (14%) and five percent (5%) for Fowler Lane and Blackwood Road, respectively, to arrive at estimated 2021 traffic volumes. Traffic volume estimates were generated for the intersection of South 27th Avenue and Kurk Drive through trip generation projections and traffic assignment for existing and remaining residential development from Meadow Creek Subdivision within the vicinity of the intersection projected to pass through the intersection for average weekday as well as AM and PM peak hour vehicular trips. Existing Conditions Capacity and level of service (LOS) analyses were performed for existing traffic conditions based on existing traffic control and intersection geometry. The analyses of existing traffic operations found that each of the study area intersections are currently operating within acceptable levels of service (LOS C or better). No specific crash experience concerns were identified at any of the study area intersections. Projected Traffic No substandard traffic operations or other transportation related impacts were identified through the year 2026 analyses for estimated non-site or total traffic conditions with the inclusion of the proposed Buffalo Run development at any of the study area intersections. 3 Traffic Impact Study Update – Buffalo Run October 2021 Proposed Study Area Development Proposed Development Plan Buffalo Run Bozeman, LLC is proposing the Buffalo Run development that is to include 180 multifamily units, 29 rowhouses, and 28 duplex units for a total of 237 proposed residential dwelling units. The development will also include a community center for use by the residents within Buffalo Run as well as their invited guests. Primary access to the development is proposed via Kurk Drive that would include an extension from the west boundary of Meadow Creek Subdivision (west of South 30th Avenue) westerly to Fowler Lane. The proposed development is located on the site of an existing residence with an outbuilding that includes some limited agricultural use on the north half of the southwest quarter of the southwest quarter of Section 23, Township 2 South, Range 5 East, Principal Meridian of Montana (N ½ SW ¼ SW ¼ of Sec. 23, T2S, R5E, P.M.M.). The project is bounded by Fowler Lane to the west, Meadow Creek Subdivision park land to the east, agricultural land to the north, and mixed residential-agricultural land use to the south. The area offers a mixture of moderate density residential uses and agricultural lands. The proposed site plan is shown in Figure 1 below. The site location and study area are shown in Figure 2 on the following page. Figure 1: Overall Site Plan 4 Traffic Impact Study Update – Buffalo Run October 2021 Figure 2: Site Location & Study Area 5 Traffic Impact Study Update – Buffalo Run October 2021 Off-Site Roadway Improvements Fowler Lane With the development of Buffalo Run, Fowler Lane is proposed to be paved from Blackwood Road north to Stucky Road. Adjacent to the proposed development, Fowler Lane would be completed to a City of Bozeman minor arterial standard. The currently proposed street section for Fowler Lane is shown in Figure 3 below. Figure 3: Currently Proposed Fowler Lane Typical Section Adjacent to Buffalo Run (Looking North Along Centerline) South 27th Avenue The western half of South 27th Avenue between Kurk Drive and West Graf Street that is currently missing is proposed to be completed with the development of Buffalo Run. The proposed improvements would generally match a City of Bozeman collector roadway standard with consideration to the existing typical section between Kurk Drive and Blackwood Road installed with the Meadow Creek Subdivision development. The existing fully built section includes a single travel lane in each direction, northbound and southbound, separated by a raised median. Left turn lanes are included at primary intersections. The existing fully built section and the area where the western portion is proposed to be completed can be seen in Figure 4 on the following page. Development Horizon It is anticipated that the proposed Buffalo Run development will occur over the next five-year period with full build-out and occupancy projected by the fall of 2026. 6 Traffic Impact Study Update – Buffalo Run October 2021 Figure 4: Existing South 27th Avenue Corridor within Meadow Creek Subdivision 7 Traffic Impact Study Update – Buffalo Run October 2021 Transportation Elements of the Proposed Development Trip Generation Estimated trip generation for the proposed development was derived utilizing rates published by the Institute of Transportation Engineers (ITE) in the Trip Generation Manual, 11th Edition. The rates were based on multifamily housing (low- and mid-rise) land uses with a general urban/suburban setting or location and the proposed number of dwelling units as the independent variables. Based on the ITE trip generation rates, the proposed project is estimated to generate 1,200 average weekday vehicular trips as well as 92 and 101 vehicular trips during the weekday, AM and PM peak hours at full build-out. Pedestrian and/or bicyclist related trips were also estimated at 13 and 15 trips during the weekday, AM and PM peak hours at full build-out, respectively. The estimated project trip generation for the proposed development is presented in Table 1 below and is provided in Appendix B.

Various methods are available for estimating trip distribution, including the analogy, trip distribution model, area of influence, origin-destination (O-D), and surrogate data methods. This study utilizes a combination of the analogy method that bases the trip distribution on existing travel patterns in the area, and the O-D method that considers likely trip origins and destinations. Figure 5 on the following page shows the estimated primary trip distribution with the development proposal for Buffalo Run. 8 Traffic Impact Study Update – Buffalo Run October 2021 Figure 5: Primary Trip Distribution Traffic Assignment The assignment of development traffic provides the information necessary to determine the level of site related impacts to the area roadway system and intersections. It involves determining the volume of traffic and its movements within the transportation system. At a minimum, trip assignment must also consider route choice, how the existing transportation system functions, and travel times to and from the development. The resulting traffic assignment within the study area is shown in Figure 6 on the following page. 9 Traffic Impact Study Update – Buffalo Run October 2021 Figure 6: Site Traffic Assignment 10 Traffic Impact Study Update – Buffalo Run October 2021 Pedestrians & Bicyclists Sidewalk connections are proposed within the proposed Buffalo Run development and on the adjacent roadway network that would provide connectivity among the residential units as well as the community center. A shared-use pathway is proposed within the development as well along with an included segment on the east side of Fowler Lane adjacent to the site. Provisions for bicycle parking are included in accordance with City of Bozeman regulations. The incorporated pedestrian and bicyclist facilities would link to existing available features within the Meadow Creek Subdivision development to the east. The proposed pedestrian and bicyclist facilities can roughly be seen in Figure 1 on page 3. Transit Service As transit is not currently available nor is service to the immediate area proposed in the future within the development timeframe of Buffalo Run no specific improvements are proposed with the project. Existing Conditions Study Area Land Use Currently, the site of the proposed Buffalo Run development is the site of an existing residence with an outbuilding that includes some limited agricultural use on the north half of the southwest quarter of the southwest quarter of Section 23, Township 2 South, Range 5 East, Principal Meridian of Montana (N ½ SW ¼ SW ¼ of Sec. 23, T2S, R5E, P.M.M.). The project is bounded by Fowler Lane to the west, Meadow Creek Subdivision park land to the east, agricultural land to the north, and mixed residential-agricultural land use to the south. The area offers a mixture of moderate density residential uses and agricultural lands. Transportation Network Some of the key characteristics of the existing roadways and intersections within the study area are listed in the sections that follow and are provided in Table 2 on page 11. All roadways are under the jurisdiction of the City of Bozeman except Fowler Lane, which is jointly under City of Bozeman and Gallatin County jurisdiction. Study Area Roadways Fowler Lane Fowler Lane is functionally classified as a minor arterial by the Bozeman Transportation Master Plan (BTMP) prepared by Robert Peccia & Associates and Alta Planning + Design dated April 25, 2017. Within the vicinity of the proposed Buffalo Run development, the roadway provides a link between South 19th Avenue to the south where it intersects with Hyalite Canyon Road and Stucky Road to the north where it currently ends in a T-intersection. The BTMP does identify a future extension of Fowler Lane north to West Garfield Street. Within the study area, Fowler Lane is a currently a two-lane, gravel roadway with a surface width of approximately 24-feet. The posted speed limit on the roadway is thirty-five miles per hour (35 mph). 11 Traffic Impact Study Update – Buffalo Run October 2021 Kurk Drive Kurk Drive as an east-west local residential street within Meadow Creek Subdivision from its western terminus at Ainsworth Park (the western boundary of the subdivision) east to its intersection with Lance Drive. It has a top-back of curb to top-back of curb width of approximately 35-feet. This allows for single travel lanes in each direction with available space for on-street parallel parking on both sides of the roadway. A five-foot wide boulevard sidewalk is included on the south side of the roadway from the western end of the roadway to South 27th Avenue. Boulevard sidewalk is provided on both sides of the roadway east of South 27th Avenue for approximately 740-feet. The speed limit on Kurk Drive is 25 mph by statute. South 27th Avenue The BTMP classifies South 27th Avenue as a collector roadway, serving as a north-south primary route within the vicinity of the proposed Buffalo Run. It is presently constructed within Meadow Creek Subdivision from Blackwood Road to the south and northerly to West Graf Street. Recently, South 27th Avenue has also been extended north of West Graf Street to Cielo Way within the Gran Cielo Subdivision development. The full collector roadway section of South 27th Avenue was installed between Blackwood Road and Kurk Drive with a top-back of curb to top-back of curb width of approximately 62-feet. The roadway includes single travel lanes in each direction along with dedicated bike lanes in each direction separated by a raised median. The speed limit is 25 mph by statute. Turn lanes are provided at key primary intersections. Only the east half of the roadway was installed with the Meadow Creek Subdivision development from Kurk Drive north to West Graf Street. Boulevard sidewalks are installed on both sides of the roadway between Blackwood Road and Kurk Drive, and they are also included on the east half completed section from Kurk Drive to West Graf Street. Study Area Intersections The existing intersections evaluated as a part of this study and their current traffic control plus configurations are summarized in Table 2 below.

Other than those included on the fully completed segment of South 27th Avenue between Blackwood Road and Kurk Drive, no dedicated bicycle facilities are currently included within the study area. No pedestrian or bicyclist facilities are currently provided on Fowler Lane. Streamline transit service does not currently have any routes that provide direct service within the study area. Traffic Volumes COVID-19 Effects on Availability of Count Data Due to the coronavirus disease 2019 (COVID-19) pandemic, reliable counts of existing traffic volumes within the study area were not able to be obtained at the time of initial study preparation for the proposed Buffalo Run development. Estimated Traffic Volumes Traffic volume estimations for the study area intersections were developed through vehicle trip generation projections and evaluation of previous modeling. The total estimated traffic volumes for the existing study area intersections are summarized in Figure 7 on page 14. The two existing intersections included as a part of this traffic impact study update utilized the following methodology for estimating existing traffic volumes: Fowler Lane & Blackwood Road Estimated traffic volumes were developed from modeling completed as part of the Transportation Planning Study for South 27th Avenue & the Montana State University Innovation Campus prepared by Morrison-Maierle in June 2014. Modeled volumes were derived through historic data from previous transportation master plans and the application of estimated average annual growth rate (AAGR) percentages of fourteen percent (14%) and five percent (5%) for Fowler Lane and Blackwood Road, respectively, to arrive at estimated 2021 traffic volumes. South 27th Avenue & Kurk Drive Traffic volume estimates were generated for the intersection of South 27th Avenue and Kurk Drive through trip generation projections and traffic assignment for existing and remaining residential development from Meadow Creek Subdivision within the vicinity of the intersection projected to pass through the intersection for average weekday vehicular trips. Estimated trip generation for the existing and residential development was based on the following lots within the subdivision: ▪ Block 9 | Lots 13 and 22-33 ▪ Block 10 | Lots 1-6, 7B, 8B, 9B, 10B-1, 11A-1, and 12-26 ▪ Block 11 | Lots 1-16 ▪ Block 12 | Lots 1-14 ▪ Block 14 | Lots 1-22 The estimated trip generation for the above lots was developed using the ITE Trip Generation Manual, 11th Edition using Land Use Code 210 – Single-Family Detached Housing and Land Use Code 220 – Multifamily Housing (Low- Rise) with a general urban/suburban setting or location and the number of dwelling units as the independent variables. The total estimated trip generation for the above lots within Meadow Creek Subdivision is summarized in Table 3 on the following page and is included in Appendix B. 13 Traffic Impact Study Update – Buffalo Run October 2021 Table 3: Estimated Trip Generation for South 27th Avenue & Kurk Drive Intersection Volumes from Meadow Creek Subdivision Average Weekday Trip Ends Weekday, AM Peak Hour Trip Ends Weekday, PM Peak Hour Trip Ends Land Use ITE Code Quantity Enter Exit Total Enter Exit Total Enter Exit Total Single-Family Detached Housing 210 106 DU Total Estimated Vehicle Trip Ends 533 533 1,066 21 58 79 66 39 105 Total Estimated Walk and/or Bike Trip Ends 2 2 4 4 4 8 Residential Condominium / Townhouse 220 3 DU Multifamily Housing (Low-Rise) Total Estimated Vehicle Trip Ends 11 11 22 0 2 2 1 1 2 Total Estimated Walk and/or Bike Trip Ends 0 1 1 1 0 1 Total Units = 109 DU Total Estimated Vehicle Trip Ends = 544 544 1,088 21 60 81 67 40 107 Total Estimated Walk and/or Bike Trip Ends = 2 3 5 5 4 9 DU = Dwelling Units Crash Experience Traffic safety conditions in the study area were documented by reviewing the crash history of the study area intersections using data provided from the MDT crash database. Public crash information for the period 2015 through 2019, the latest five years available, were reviewed. MDT reported one crash within the study area occurring at or near intersections over the five-year period. This one crash was near the intersection of Fowler Lane and Blackwood Road at night in August 2018. Limited data is available through the public crash information provided by MDT. Additional crash information such as type; weather, roadway, and lighting conditions; number of vehicles, pedestrian, or bicyclist involvement; age and gender of drivers; and other potentially contributing conditions can be obtained through a review of the specific crash reports. Projected Traffic Through Traffic Projections Growth Rate Projections Estimated traffic volumes for the 2026 analysis year due to growth within the study area were forecast by applying AAGR percentages to estimated existing 2021 traffic volumes. An assumed AAGR value of 14.00% was applied to through movements on Fowler Lane at its intersection with Blackwood Road. Turning movements from and onto Blackwood Road at that intersection utilized an assumed AAGR of 5.00%. No growth is anticipated for the intersection of South 27th Avenue and Kurk Drive without additional development in the area. Projected Through Traffic Volumes Estimated 2026 through traffic (background) volumes from growth rate projections within the study area are shown in Figure 8 on page 15. 14 Traffic Impact Study Update – Buffalo Run October 2021 Figure 7: Estimated 2021 Existing Traffic Volumes 15 Traffic Impact Study Update – Buffalo Run October 2021 Figure 8: Estimated 2026 Through Traffic Volumes 16 Traffic Impact Study Update – Buffalo Run October 2021 Total Traffic Projections Estimated 2026 total traffic volumes include the combination of projected non-site traffic with forecast volumes for the proposed Buffalo Run development, which are provided in Figure 9 on the following page. Transportation Analyses Analysis Scenarios To identify significant project impacts, the following scenarios for study area intersections were evaluated: ▪ Estimated Existing Conditions (2021) Consists of an operational analysis of year 2021 counts estimated as part of this study. ▪ No Build Scenario – Estimated 2026 Through Traffic Volumes Consists of projected, non-site through traffic volumes resulting from growth outside as well as within the study area. ▪ Full Buildout Scenario – Estimated 2026 Total Traffic Volumes Consists of estimated 2026 through traffic volumes in combination with forecast traffic from the proposed Buffalo Run development. Analysis Methodologies Operations The intersection analyses employ methodologies based on empirical research conducted by the Transportation Research Board (TRB) and other authorities, utilizing level of service (LOS) as the performance measure to evaluate the cumulative effects of such things as travel speed, traffic volumes, roadway and intersection capacity, travel delay, and traffic interruptions. Operating conditions are designated as LOS A through LOS F, representing the most to least favorable. LOS for intersections is determined by control delay, which is defined as the total elapsed time from when a vehicle stops at the end of a queue to the time the vehicle departs from the stop line. The total elapsed time includes the time required for the vehicle to travel from the last-in-queue position to the first-in-queue position, including deceleration of vehicles from the free flow speed to the speed of vehicles in the queue. LOS characteristics based on varying durations of average vehicle delay as listed in the Highway Capacity Manual, 6th Edition | A Guide for Multimodal Mobility Analysis (HCM) published by the TRB are summarized in Appendix A. The methodology used to determine the level of service for unsignalized intersections is based on Chapter 20 of the HCM for two-way stop controlled (TWSC) and Chapter 21 for all way stop controlled (AWSC) intersections. The LOS criteria are applicable for both two-way and all-way stop-controlled intersections. The TWSC analyses were performed using HCS TWSC Version 7.9 developed and maintained by the McTrans Center at the University of Florida. The HCM methodology for evaluating TWSC intersections is based on gap acceptance and conflicting traffic for vehicles stopped on the minor street approaches. The critical gap (or minimum acceptable gap) is defined as the minimum time interval in the major street traffic stream that allows entry for one minor street vehicle. Average control delay and LOS for the minor street approach(es) is/are reported. LOS is not defined by the HCM for the intersection because major street traffic volumes and operations may skew the results of the LOS analyses. 17 Traffic Impact Study Update – Buffalo Run October 2021 Figure 9: Estimated 2026 Total Traffic Volumes 18 Traffic Impact Study Update – Buffalo Run October 2021 The AWSC analyses were performed using HCS AWSC Version 7.9 that is also developed and maintained by the McTrans Center. The HCM methodology for evaluating AWSC intersections is based on traffic conditions on each of the approaches to the intersection as well as driver perception and consensus. Average control delay and LOS for each approach and the whole intersection are reported. Study Scenario Analyses Intersection capacity and LOS analyses for the study scenarios were performed using the existing geometry and traffic control at each of the study area intersections except for Kurk Drive and its intersections with Fowler Lane and South 27th Avenue. Fowler Lane and its intersection with Kurk Drive would be a new intersection evaluated as a two-way stop- controlled intersection with single lane approaches, having stop control on the westbound Kurk Drive approach. The analyses for estimated 2026 total traffic conditions at the intersection of South 27th Avenue and Kurk Drive incorporate the improvements proposed with the Buffalo Run Development while maintaining all way stop control. The analyses are summarized in the following figures and detailed results are included in Appendix C. ▪ Figure 10: Traffic Operations Summary for Estimated 2021 Existing Conditions – Page 19 ▪ Figure 11: Traffic Operations Summary for Estimated 2026 Background Traffic Conditions – Page 20 ▪ Figure 12: Traffic Operations Summary for Estimated 2026 Total Traffic Conditions – Page 21 Assessment of Impacts Traffic Operations Each of the study area intersections are currently operating within acceptable levels of service and are projected to continue to do so. No additional mitigation measures at any of the included study area intersections are necessary to accommodate projected traffic contributions from the proposed Buffalo Run development based on the analyses performed as a part of this traffic impact study update. Alternative Modes of Transportation Existing Conditions Previous sections noted sidewalks are available for pedestrians within the study area on Kurk Drive to the east of the proposed Buffalo Run as well as throughout the Meadow Creek Subdivision development. Other than those included on the fully completed segment of South 27th Avenue between Blackwood Road and Kurk Drive, no dedicated bicycle facilities are currently included within the study area. No pedestrian or bicyclist facilities are currently provided on Fowler Lane. Streamline transit service does not currently have any routes that provide direct service within the study area. Proposed Development Sidewalk connections are proposed within the proposed Buffalo Run development. The sidewalks proposed with the project would provide connections to the adjacent roadways. As transit is not currently available nor is service to the immediate area proposed in the future within the development timeframe of Buffalo Run no specific improvements are proposed with the project. 19 Traffic Impact Study Update – Buffalo Run October 2021 Figure 10: Traffic Operations Summary for Estimated 2021 Existing Conditions 20 Traffic Impact Study Update – Buffalo Run October 2021 Figure 11: Traffic Operations Summary for Estimated 2026 Background Traffic Conditions 21 Traffic Impact Study Update – Buffalo Run October 2021 Figure 12: Traffic Operations Summary for Estimated 2026 Total Traffic Conditions 22 Traffic Impact Study Update – Buffalo Run October 2021 Crash Experience From data provided in the MDT crash database, no significant crash trends were identified at any of the study area intersections Further review of the data from the specific crash reports may provide insight for additional crash information such as type; weather, roadway, and lighting conditions; number of vehicles, pedestrian, or bicyclist involvement; age and gender of drivers; and other potentially contributing conditions. Site Accessibility As shown in the traffic operations analyses, the proposed extension of Kurk Drive to Fowler Lane included with the proposed Buffalo Run development is projected to function with acceptable capacity and within reasonable levels of service. Additionally, forecast average weekday traffic volumes on Kurk Drive are within City of Bozeman guidelines for local streets. Compliance with Applicable Local Codes The proposed Buffalo Run development improvements should be installed in accordance with City of Bozeman and Gallatin County requirements, as applicable. Conclusions & Recommendations Analysis of trip generation estimates, traffic operations, and considerations for alternative modes of transportation reveal that the proposed Buffalo Run development will have minimal impact on the area traffic operations. As with any development, there will be an increase in traffic volumes with the buildout of the proposed Buffalo Run. Residents in Meadow Creek Subdivision are likely to note an increase in traffic volumes on Kurk Drive that can be managed with existing intersection traffic control in-place along the corridor. Based on the analyses included herein, the following are recommended as appropriate: Study Area Roadways Fowler Lane With the development of Buffalo Run, Fowler Lane is proposed to be paved from Blackwood Road north to Stucky Road. Adjacent to the proposed development, Fowler Lane would be completed to a City of Bozeman minor arterial standard. The currently proposed street section for Fowler Lane is shown in Figure 3 on page 5. Kurk Drive Kurk Drive is proposed to be extended from its current western terminus adjacent to Ainsworth Park to Fowler Lane with the proposed Buffalo Run project. Within the proposed development, Kurk Drive would be completed to a City of Bozeman local street standard. South 27th Avenue The western half of South 27th Avenue between Kurk Drive and West Graf Street that is currently missing is proposed to be completed with the development of Buffalo Run. The proposed improvements would generally match a City of Bozeman collector roadway standard with consideration to the existing typical section between Kurk Drive and Blackwood Road installed with the Meadow Creek Subdivision development. 23 Traffic Impact Study Update – Buffalo Run October 2021 Study Area Intersections No substandard traffic operations or other transportation related impacts were identified through the year 2026 analyses for estimated non-site or total traffic conditions at any of the study area intersections. Site Circulation ▪ Internal roadways should be designed for the appropriate vehicles that may access the facility, including emergency and solid waste vehicles as well as buses, as necessary. ▪ Adequate sight distance must be preserved at driveways, internal intersections, and crosswalks for driver, pedestrian, and bicyclist safety in accordance with City of Bozeman and AASHTO standards. ▪ Stop control is recommended for site accesses to Kurk Drive as well as on the northbound approaches of the two north-south roadways within the proposed Buffalo Run development. Alternative Modes of Transportation Pedestrians & Bicyclists The proposed sidewalk and pathway connections within the proposed Buffalo Run development will allow for circulation within the development, ties to the existing network within Meadow Creek Subdivision, and provide initial improvements for future non-motorized use on Fowler Lane. Transit Service No specific additional improvements for transit service features are proposed within the Buffalo Run development. Improvements & Traffic Control Guidance Included recommendations for mitigation and the proposed Buffalo Run development improvements should be installed in accordance with City of Bozeman requirements, the most current editions of the Montana Public Works Standard Specifications, Gallatin County transportation standards, and the Manual on Uniform Traffic Control Devices. 24 Traffic Impact Study Update – Buffalo Run October 2021 References 1.

Appendix A Level of Service Concepts, Analysis Methodologies, & Standards of Significance Appendix A: Level of Service Concepts, Analysis Methodologies, & Standards of Significance | A-1 Traffic Impact Study Update – Buffalo Run October 2021 Unsignalized Intersection Level of Service The method presented in the Highway Capacity Manual, 6th Edition | A Guide for Multimodal Mobility Analysis (HCM) published by the Transportation Research Board (TRB) for evaluating unsignalized, stop-controlled intersections is based on the average total delay for each impeded movement. As used here, total delay is defined as the total elapsed time from when a vehicle stops at the end of a queue until the vehicle departs from the stop line. This time includes the time required for the vehicle to travel from the last-in-queue to the first-in-queue position. The average total delay for any minor movement is a function of the service rate or capacity of the approach and the degree of saturation. The resulting delay is used to determine the level of service as shown in Table A-1 below. Table A-1: Level of Service Criteria for Stop-Controlled Intersections Average Control Delay Level of Service (LOS) Characteristics  10 seconds A Little or no delay 10.0 – 15.0 seconds B Short traffic delay 15.0 – 25.0 seconds C Average traffic delay 25.0 – 35.0 seconds D Long traffic delays 35.0 – 50.0 seconds E Very long traffic delays > 50.0 seconds F When the demand exceeds the capacity of the lane, extreme delays will be encountered, and queuing may cause severe congestion to the intersection.
