Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 1 INTRODUCTION The following narratives serve as a summary report of operational impacts that could be associated with the proposed Nexus Point and Graf Street Apartments development. The narratives, figures, and appendix encompass all of the intersections that would potentially be impacted by these developments. Since Nexus Point and Graf Street Apartments developments are adjacent to each other and share accesses to the surrounding street system, this traffic impact study (TIS) addresses impacts of both developments combined. PROPOSED SITE DEVELOPMENT The Graf Street Apartments development is located in the northwest corner of the S 19th Avenue and Graf Street intersection (see Figure 1). The Nexus Point development is located immediately north of the Graf Street Apartments development and extends north to the Genesis Subdivision, south of Stucky Road. Developed property within the Meadow Creek Subdivision exists on the western boundary of the two developments. The Nexus Point development will accommodate 120 apartments in the first Phase of development and 120 apartments, with approximately 16,000 of office space, in Phase 2 of planned development. The Graf Street Apartments development would accommodate 198 apartments in the initial development phase and 262 apartments in Phase 2, at some future date. When fully occupied, the two properties would have 700 apartments and 16,000 sf of office space. Three internal streets would be constructed as part of the development infrastructure, as shown in Figure 1. The developments would have two main accesses to the street system. One on S 19th Avenue at the future extension of Arnold Street from S 11th Avenue to S 19th Avenue and one on Graf Street. Two minor accesses would be created via local street connections on the west side of the developments. MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 2 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 3 This Traffic Impact Study (TIS) addresses potential impacts associated with full development of the Nexus Point & Graf Street Apartments developments and includes all arterial and collector street intersections within a 0.5-mile radius of the development. Those intersections Include S 19th Avenue intersections with Kagy Boulevard, Stucky Road, and Graf Street, along with S 11th Avenue, and S 27th Avenue intersections with Graf Street. EXISTING CONDITIONS Streets & Intersections South 19th Avenue is a Principal Arterial north-south oriented roadway that begins at an intersection with Cottonwood Road, approximately 6 miles south of Graf Street, and continues north approximately 4.5 miles to an interchange with Interstate 90. South 19th Avenue has variable pavement widths and varying speed zones along its length. At its intersection with Graf Street, it is approximately 62’ wide and has two southbound through lanes; two northbound through lanes; and auxiliary northbound and southbound left-turn lanes. An extension of Graf Street from S 19th Avenue to S 3rd Avenue along with traffic signal modifications were recently constructed at S 19th Avenue & Graf Street intersection. North of Graf Street, South 19th Avenue transitions to a two lane road section and then transitions back to a wider section at S 19th Avenue’s intersection with Stucky Road, approximately 0.5 miles north of Graf Street. The intersection of Stucky Road and South 19th Avenue is similar to the Graf Street intersection except that there is only one southbound through lane on the departure side of the intersection and there are no curb and gutter sections along South 19th Avenue. The traffic signal at Stucky Road and South 19th Avenue is fully operational and provides two signal phases for the “T” type intersection. A project to extend Campus Boulevard from S 11th Avenue to S 19th Avenue is planned to be constructed in the summer of 2019 as part of the South University MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 4 District Block 5 development. That project will include pavement widening on the east side of S 19th Avenue, which will complete the east side portion of the future 5-lane roadway section and signal modifications will be made to accommodate the addition of the Campus Boulevard extension. Improvements associated with the Nexus Point and Graf Street Apartments development involves construction of the west side of S 19th Avenue from Graf Street north to the end of the adjacent study property. Graf Street and Stucky Road are both classified as Collector streets within the Urban Transportation Plan. They both provide access to residential and institutional developments west of South 19th Avenue. Both of the intersections have two approach lanes at their intersections with South 19th Avenue. Graf Street is approximately 50’ wide and accommodates a single lane of traffic in each direction with bike lanes and parking on both sides of the street. Stucky Road is approximately 40’ wide at its intersection with South 19th Avenue and tapers back to a width of approximately 28’ west of the intersection. Future improvements to Stucky Road are within Bozeman’s CIP and would include widening west of S 19th Avenue. Kagy Boulevard is currently a three lane street with bike lanes in both directions. Kagy Boulevard extends from a termini point just west of S. 19th Avenue, past the MSU campus, to rural areas east of Bozeman. Improvements to Kagy Boulevard are currently under design by the Montana Department of Transportation (MDT) and construction is slated to begin in the year 2021 or 2022. The proposed improvements include a five lane street section with dual lane roundabouts at three intersections east of S 19th Avenue. Design hour traffic was incorporated into planning of the construction project and already includes total development of the Nexus Point & Graf Street developments as well as all other platted and potential developments that could exist in the design year of 2038. MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 5 South 11th Avenue extends from a point south of Graf Street, thru the MSU campus, to an intersection with Durston Road. South of Kagy Boulevard, it currently operates with one lane for each direction of travel, a center turn lane, and bikes lanes on either side. At its intersection with Kagy Boulevard, it accommodates a separate left-turn lane and a thru/right-turn lane on the northbound and southbound approaches. The eastbound and westbound approaches to that intersection have the same lane configuration and the traffic signal utilizes protected/permissive signal phasing for eastbound left-turns on Kagy Boulevard. Graf Street is a collector street that begins approximately one mile west of S 19th Avenue and extends east to its intersection with S 3rd Avenue. The portion of Graf Street between S 19th Avenue and S 11th Avenue was constructed approximately 2-years ago and has two thru traffic lanes and a center turn lane available to accommodate future development along its length. A single lane roundabout controls traffic at its intersection with S 11th Avenue. Arnold Street is an east-west residential street that begins just east of S. 3rd Avenue and terminates at barricades approximately 0.3 miles west of S. 3rd Avenue adjacent to an elementary school. The site improvements for Allison Subdivision would extend Arnold Street from the east to S 11th Avenue. Future development between S 11th Avenue and S 19th Avenue will eventually extend Arnold Street to the west, intersecting S 19th Avenue at the Arnold Street access to the Nexus Point development. S 27th Avenue does not currently exist north of Graf Street, but a portion of it will be constructed as part of the Gran Cielo Subdivision development improvements in the summer of 2019. Future developments north of Gran Cielo will complete a connection between Graf Street and Stucky Road that will eventually became part of the S 27th Avenue collector street. Graf Street will also be extended to the west along the southern boundary of Gran Cielo Subdivision. These improvements will create a new 4-legged intersection. At the present time, the MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 6 intersection of Graf Street and S 27th Avenue has 2-legs and operates as a sharp horizontal curve in the roadway. Existing Traffic Volumes Mio-vision video traffic counters were used to count traffic at all of the potentially impacted intersections in 2018 and 2019 (see Appendix A). Even though 2018 traffic counts for most of the Intersections were available, the extension of S11th Avenue from Graf to Kagy was not open until late summer of 2018, after traffic counts were completed. In comparing the 2019 counts to the 2018 counts, it could be seen that there was a significant traffic shift created by the S 11th Avenue extension, at all of the intersections, with less traffic on Kagy Boulevard and more traffic on Graf Street and S 11th Avenue. All of the counts were balanced to account for variations attributed to different count days and months. Figure 2 illustrates traffic counts that represent the existing (2019) am and PM hour volumes that were used as the baseline for capacity calculations within this study. Also shown in Figure 2, are the Average Weekday Traffic (AWT) volumes that were calculated using the percentage variations that were extracted from earlier 24 hour counting periods. Pedestrian volumes for each intersection having any significant pedestrian activity are also noted in Figure 2. Even though bicycle traffic was noted during the counting periods, it was not significant enough to factor into the analysis. Speeds Speed data was also collected with the electronic counters, specifically on South 19th Avenue north of Graf Street. Appendix B contains the statistical analysis of speed data for that location. It was determined from the speed statistics that the southbound traffic had an 85th percentile speed of approximately 54 miles per hour (mph) which was identical to the 85th percentile speed of 54 mph in the northbound direction. The posted speed limit of 50 mph appears to be in an acceptable range of 85th percentile speeds. MARVIN & ASSOCIATES 1300 N.

Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 8 Existing Capacity Capacity calculations were completed for the four of the study intersections. Table 1 summarizes the results of those calculations using Delay, Level-of- service (LOS), and Vehicle Queue projections as Measures of Effectiveness (MOE). Capacity calculations can be found in Appendix C of this report. All intersections currently operate at LOS “C” or better. Only one intersection approach operates below LOS “C”. The eastbound approach to S 19th Avenue and Kagy Boulevard operate at LOS “D” in the peak am hour. This approach lane only accommodates 33 vehicles during that hour of the day.

Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 9 DEVELOPMENT TRAFFIC PROJECTIONS Trip Generation The proposed development of Nexus Point & Graf Street Apartments development includes a mixture of apartments and general office buildings. Approximately 700 apartment units and 16,000 square feet of office space comprise the development plans. The current ITE Trip Generation Report is Edition 10, which has a number of apartment land use codes. After careful review of apartments characteristics, it was determined that ITE Land Use Code 221 “Mid-rise Apartments” would best represent the proposed apartment being planned in the Nexus Point and Graf Street Apartments development. Land Use Code 710 “General Offices” was used for the office buildings in Phase 2 of the Nexus Point development. Table 2, on the following page, summarizes the total vehicular and pedestrian/bike trip generation for this development, based upon the above noted ITE Land Use Codes. The 700 apartment units would generate approximately 3,987 trips on the average weekday. During the peak AM hour, there would be 256 trips and during the peak PM hour there would be 313 trips. Adjustments for trip mode were estimated based on walking distance less than a mile to and from surrounding attractors including the MSU campus. A relatively low estimate of 10% of the trips would be made by bicycle or pedestrian modes. The 10% estimate reflects the 2010 census data for work trips by mode, which indicates that 5% of work trips are by bicycle and 9% are made by walking within the Bozeman urbanized area. The 10% estimate for this study was used instead of 14% because the site would not immediately be surrounded by urban development and would be less likely to generate pedestrian and bicycle trips meeting average conditions in the Bozeman urban area, even though the proximity to the MSU campus would probably encourage higher than average bicycle usage.

The ITE Trip Generation Handbook indicates that ICT adjustments are typically evaluated when developments areas range between 100,000 and one million square feet. The combined area of the two study subdivisions is approximately 200,000 square feet and share internal streets and paths. In this case, the mixed use involves a community center which includes services tailored to the needs of the apartment dwellers, such as open space, a pool, and a club house. When considering that the apartments would most likely be occupied by younger age residents, the community center has the potential to attract a substantial number of trips. It was estimated that approximately 5% of the trips would be Internal Capture Trips. MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 11 Adjustments for trip mode and classification results in net vehicular trips of 3,389 AWT, 217 trips in the peak AM hour and 266 in the peak PM hour. Overall, the trip generation rates contained herein would produce the maximum vehicular traffic volumes that could be attributed to this development. Trip Distribution The apartment complex within the study site will not be leased exclusively by students or workers at MSU and lacking any kind of projection on how many students and MSU workers will occupy the apartments, the most accurate method of distributing traffic is to mirror travel patterns from adjacent residential developments. Disaggregation of directional movements at surrounding intersections results in a valid and dependable method of determining the relatively travel demand that exists between origins and external destinations. Therefore, trip distribution for this study was based upon existing directional traffic movements at key intersections adjacent to the development site. The calculated trip distribution percentages are shown in Figure 3. Typically trip distribution percentages are shown on key streets within the study boundaries and not extended to intersections external to the study area. What is not shown, in this case, is the distribution of trips north of Kagy Boulevard on S 19th Avenue that actually include trips that go to or come from the campus on Lincoln Street and on College Street. Ten percent of the trips would be destined to MSU on S 11th Avenue and all of the 4% trips on the Campus Boulevard extension would be destined to MSU. All things considered, trips that would appear as traffic on MSU Campus Streets would be approximately 44%. This indicates that the MSU Campus would be a major attraction for trips to and from the site development. MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 12 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 13 Travel times to and from areas within the development to and from adjacent street accesses were also considered in modeling of directional routing. Figure 3 presents the overall distribution of site generated trips to and from the existing street system. Approximately 43% of development generated trips would be directed to and from the north/west on S 19th Avenue, with 44% of the trips directed to and from the east/north on Kagy, Campus and Graf Street. Minor attractions south of the site would result only in 8% of the total vehicular trips using S 19th Avenue to and from the site. In the future, when S 27th Avenue connects Graf Street and Stucky Road, approximately 4% of the trips would utilize Graf Street to access Stucky Road. Also, when Arnold Street connects S 19th Avenue and S 11th Avenue, 4% of the trips to and from the north and east would use Arnold Street rather than Campus Boulevard. Figure 3. also includes distribution percentages at key intersections to illustrate distribution overlap conditions that occur specifically along S 19th Avenue north of Graf Street and at the intersection of Graf Street and S 19th Avenue. Without the directional turn percentages shown, it would appear that 68% of the site access traffic would turn left onto S 19th Avenue. In actuality, 11% of the trips would be directed to and from the south and 57% would be directed to and from the north. Site access distributions are based on the least travel time paths from the internal subdivision streets to and from the adjacent streets. All of the site access distributions are based on “Unconstrained” conditions, where intersection delays based on capacity constraints are not considered in traffic distribution. Operational constraints are considered in the final traffic assignment analysis. The intersection of Discovery Drive and Arnold Street would only serve trips with an origin or destination on to Stuckey Road (4% of total) and the only segment of the site development that would benefit from routing through the local streets to Stuckey Road would be a small segment of the northwest corner of the Nexus Subdivision representing about 5% of the total development. The distribution on MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 14 Discovery Lane would then amount to approximately 0.2% trips which would be 6 vehicles on the average weekday and 0.5 vehicles in the peak pm hour. It would be meaningless to include this intersection within the study impact analysis for less than one additional vehicle in the peak pm hour. Site Traffic Assignment Site traffic assignments were completed using the trip generation projections in Table 2 and the trip distribution percentages discussed in a preceding section. The traffic assignment projection is based on the development of Nexus Point & Graf Street Apartments with access to S 19th Avenue and Graf Street. It is also assumed that the Campus Boulevard extension west to S 11th Avenue and related improvements to the traffic signal at Stucky Road and S 19th Avenue will be in-place prior to any development within the study site. This assumption is based on knowledge that the project is in the final stages of design and there is a high probability that construction will begin in the year 2020. From our experience with past projects in Bozeman, it is very likely that any significant development within the study site would take 2 to 3 years. If the Campus Boulevard extension is not completed within the next 2 to 3 years, it would likely be due to economic conditions which would also affect the construction schedule of the study development. For these reasons, it is believed that the assumption is valid. If for any reason that the Campus Boulevard extension is not completed prior to full development of the study site, the traffic assignment would only amount to 10 vehicles in the peak pm hour which would not appreciably change any of the study conclusions. The traffic assignments shown in Figure 4 illustrate the peak AM and PM hour site traffic at the key intersections, along with average weekday vehicular site traffic on the street system links.

Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 16 Traffic Redistribution Since the proposed development’s internal streets would connect to existing local streets on the site’s western boundary, there is some potential for existing traffic to use Arnold Street to access S 19th Avenue. Travel time calculations were completed to determine shortest routes using Arnold Street instead of Graf Street or Stucky Road. It was determined that the Arnold Street connection to S 19th Avenue would have a slightly longer travel time than the Stucky Road or Graf Street paths to S 19th Avenue. Therefore, the future Arnold Street Connection would not redistribute traffic from developments west of the site property boundaries. TRAFFIC IMPACTS Existing Plus Development Traffic Volumes Figure 5 illustrates the combination of existing AM and PM design hour traffic volumes and site development generated traffic at each of the key study intersections for the Nexus Point & Graf Street Apartments development. Also shown in Figure 5 are the resultant AWT volumes and the percentage increases over existing traffic that would be attributable to this development. Graf Street west of S 19th Avenue would have the highest percentage increase of any of the area streets at 49%. Graf Street, east of S 19th Avenue, would have an increase of 23% AWT. S 19th Avenue, north of Arnold Street would have the highest volume increase, which would translate into a 20% increase over existing traffic and 13% north of Stucky Road. Both Graf Street and S 11th Avenue east and north of their intersection would see an increase greater than 10% of existing AWT. All of the other existing streets would have percentage increases less than 10%. It should be noted that normally, traffic impacts on streets that are less than 10% are not considered to be significant because daily traffic variations on any street routinely exceed 10%. MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 17 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 18 Existing Plus Site Traffic Capacity Table 3 presents a summary of capacity calculations for existing plus full development site traffic (see Appendix C). Table 3 indicates that almost all of the study intersections would operate at LOS “C” or better during both the AM and PM hour periods, if the Nexus Point & Graf Street Apartments developments existed today. The only movements operating below LOS “C” would be the eastbound approach at the intersection of S 19th Avenue and Kagy Boulevard, which would remain at LOS “D” in the peak AM hour and in the peak PM hour, that approach would also be degraded to LOS “D”. Both of the site access would operate at acceptable levels. All movements at the access intersections would be LOS “A” except for the eastbound Arnold Street access which would operate at LOS “B” in the AM hour and LOS “C” in the PM Hour. In comparing Table 3 to Table 1, it can be seen that there are slight variations in the LOS and delay for individual approaches, but the overall intersection operations would not experience LOS changes. Queue lengths would vary within individual lanes, but none of the lanes would experience an increase in vehicle queues exceeding available storage or interfere with access movements adjacent to the intersections.

Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 21 Future Traffic Volumes Traffic projections for future conditions were developed by incorporating all of the area’s planned development including all in-process platting and in-fill of platted subdivisions. Various design studies were also input to the projections including the Kagy Boulevard improvements; the Campus Boulevard extension project; the South University District development projects; and the Graf Street and S 3rd Avenue intersection improvement projects. Traffic projections included in those projects included the following known developments: Yellowstone Theological Institute Allison Annex Allison Subdivision South University District Phase 2 Apartments South University District Subdivision Block 5 COS 2661A Boylan Addition Kiefer Property MSU Parking Garage MOR Commercial Lot South Towne Square Bozeman Health Sub Area Zimmer-Nash Property Burkhart Property Meadow Creek Subdivision Gran Cielo Subdivision Figure 7 illustrates the traffic volume projections at all of the study intersections, including the site access intersections with S 19th Avenue and Graf Street. The AWT volumes shown in Figure 7 are substantially higher than existing traffic volumes, with S 19th Avenue north of Kagy Boulevard exceeding 31,000 vehicles per day in the year 2038. These volumes may overstate the future demand on S 19th Avenue somewhat because it was uncertain whether the S 27th Avenue collector street corridor would extend north of Stucky Road by the year 2038. That corridor could relieve traffic demand on S 19th Avenue to some extent and change traffic patterns on S 19th Avenue. MARVIN & ASSOCIATES 1300 N.

Capacity calculations (see Appendix C) indicate that all intersections would operate at LOS “C” or better during both the AM and PM hour periods given year 2038 traffic projections and intersection conditions that will exist in the future. The only exceptions would be the southbound thru movement at S 19th Avenue & Stucky Road, which would operate at LOS “D” during the peak PM hour. The Arnold Street eastbound site approach would operate at LOS “F” during the peak AM and peak PM hours. Queue lengths would vary within individual lanes, but none of the lanes would experience an increase in vehicle queues that would exceed available storage or interfere with access movements.

Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 24 CONCLUSIONS The development of the Nexus Point & Graf Street Apartments development property, as proposed, would not substantially impact the safety and efficiency of any of the area streets or intersections if it existed at the present time. The eastbound approach on S 19th Avenue, currently operates at LOS “D” in the AM and PM hours. However, the approach volumes are so low on that approach during the peak hour periods that the overall intersection operates at LOS “C” serving the majority of entering traffic. Considering that the Kagy Boulevard and S 19th Avenue intersection will be reconstructed as a part of the MDT project in the next three to four years, actual development in the Nexus Point & Graf Street Apartments development would not be advanced sufficiently to impact current operations during that short time period. Future traffic (year 2038) on area streets is projected to increase significantly over current traffic volumes. Even with significant growth, in combination with full development of the Nexus Point & Graf Street Apartments development, all of the key intersection would operate at or above LOS “C” and no mitigating measures would be required at the study intersections. At some point prior to the year 2038, alternative control measures may be required at the intersection of Arnold Street and S 19th Avenue. A traffic signal may be warranted by the year 2038. Other measures could be considered such as eliminating left turns from the eastbound and westbound approaches. This would then force site development traffic having a destination north of the site, to use Graf Street, which has more than enough reserve capacity to accommodate the eastbound left turn movement. With the high volume of future traffic projected on S 19th Avenue, MDT may, at some future date, consider a raised median on S 19th Avenue which would then allow elimination of some access movements. However, Arnold Street should operate in an efficient manner during the interim period. MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 Nexus Point & Graf Street Apartments Development Traffic Impact Study Page 25 MDT turn lane warrants were investigated for the southbound right turn movement at the Arnold Street intersection with S 19th Avenue. It was determined that a right turn lane would be warranted for that movements based on the existing plus full development site traffic volumes shown in Figure 5 with the proposed five lane street section. However, the right turn lane would not meet warrants until a point in time after Phase 1 developments are completed and fully occupied. At that point, an evaluation of traffic growth on S 19th Avenue can be reevaluated and a more specific plan could be developed for a traffic signal or roundabout installation. If a future traffic signal or roundabout is constructed, the warrants for an auxiliary right-turn lane would not apply. Thus, provisions should be made for a future traffic signal at the Intersection of S 19th Avenue and Arnold Lane.
