Morrison Traffic Impact Study llllliiiiii Maierle+urveyors•planners•scientistsBozeman West-Apartments I Bozeman, Gallatin County, Montana Purpose of Report and Study Objectives This traffic impact study summarizes the potential impacts from the proposed Bozeman West - Apartments proposed to be located in Bozeman, Gallatin County, Montana. The information presented in this report is intended to evaluate the safety and operational aspects of the transportation system in the area of the proposed development under existing conditions as well as with estimated impacts. Study recommendations and conclusions are intended to provide guidance with respect to the short- and long term function of the proposed site accesses and the area transportation system. Proposed Development Location The proposed Bozeman West -Apartments project is located in Bozeman, Gallatin County, Montana on Lot B of Certificate of Survey No. 1256A situated in the northeast quarter of Section 2, Township 2 South, Range 5 East, Principal Meridian of Montana. Generally, the property is bordered by Tschache Lane to the south, vacant land to the east and west, and an existing condominium development to the north. The site location is depicted in Figure 1 on the following page. Development Description The proposed Bozeman West - Apartments project is proposed to consist of 216 apartment units as well as a community building and a maintenance building for the site located on a total site area of approximately 440,464 square feet (ft2) or 10.11 acres. The development is estimated to generate a total of 1,433 average weekday trips as well as 110 weekday AM and 136 PM peak hour trips. There are two site accesses to Tschache Lane included with the proposed development. The preliminarily proposed site layout is shown in Figure 2 on page 3. Zoning Lot B of Certificate of Survey No. 1256A is currently zoned R-4 (Residential High Density) under the City of Bozeman's zoning designation. As provided in the City of Bozeman Unified Development Code, "The intent of the R-4 residential high density district is to provide for high-density residential development through a variety of housing types within the city with associated service functions. This will provide for a variety of compatible housing types to serve the varying needs of the community's residents. Although some office use is permitted, it shall remain as a secondary use to residential development. Secondary status shall be as measured by percentage of total building area." 1 :• :• • • _ Q RD r o s e z ui I � `i ► ,_ CL • ;�; > BAXTER LN W' 90 ^� w OAK ST' > Ip Q , w w w -�� t•.

Development Horizon It is anticipated that the proposed Bozeman West -Apartments will be fully developed and occupied by the year 2020, assuming full buildout and occupancy. Therefore, this study will assess any impacts this development may have on the area transportation system within this timeframe. Existing Area Conditions Study Area Area of Influenee The transportation impacts from a development are largely dependent on its location and size as well as the characteristics of the surrounding transportation system. The significant impacts to the adjacent transportation system will generally be within a limited area from the site. The proposed Bozeman West - Apartments is not significantly large in size from a traffic generation standpoint, having fewer than 200 estimated trips during both the weekday AM and PM peak hours. Therefore, it is not anticipated that the development would have significant impacts beyond the proposed site accesses and key intersections within proximity to the proposed project. Study Area Land Use Presently, the proposed site is vacant. As stated previously, the site is bordered by Tschache Lane to the south. Across Tschache Lane from the proposed development is Rose Park - existing, largely undeveloped parkland. Immediately west of the site is vacant land that is also currently zoned R-4, which is adjacent to North 27th Avenue. Across North 27th Avenue to the west is an existing residential area. To the north of the proposed Tschache Lane Apartments is an existing condominium development, Baxter Springs Condominiums. To the east of the site is vacant land that is not within the limits of the City of Bozeman, and it is generally bisected by Catron Creek that travels from south to north through that property. Further east is an existing Home Depot home improvement warehouse. Site Accessibility Transportation!network As stated previously, the study area for the proposed Bozeman West - Apartments development will focus on key intersections within proximity to the proposed site. The roadways and intersections included within this study are noted on the following page. 4 ..

Beginning at Caspian Avenue just west of Davis Lane, Tschache Lane generally travels east-west before terminating in a temporary cul-de-sac east of Sacco Drive, which is east of North 19th Avenue. Adjacent to the proposed Tschache Lane Apartments, the roadway has a top-back of curb to top-back of curb (TBC-TBC)width of approximately 38 feet. North 27th Avenue North 27th Avenue is classified as a collector roadway by the Greater Bozeman Area Transportation Plan 2007 Update (GBATP). Presently, North 27th Avenue links Durston Road to the south of the proposed Tschache Lane Apartments northerly to Baxter Lane. North of its intersection with Baxter Lane, North 27th Avenue changes to Thomas Drive, which is a local roadway primarily serving a number of residential properties on the north side of Baxter Lane. Within the study area from Tschache Lane to Baxter Lane, North 27th Avenue has been built to the City of Bozeman collector standard roadway with a raised center median, which has a TBC-TBC width of 62 feet. This includes a single travel lane, bike lane, and parking on each side of the roadway. 5 Traffic Impact Study No Morrison iiiiiiiii Bozeman West-Apartments I Bozeman, Gallatin County, Montana Maierle rr:o�nrrr+ irrYur+ ,rinrrre+ +r irnr.sl+ Baxter Lane Within the project study area, Baxter Lane is classified as a minor arterial roadway by the GBATP. Baxter Lane serves as an east-west alternate route for commuters from the outlying areas to Bozeman and commercial areas on the North 19th Avenue and North 7th Avenue corridors. It provides a continuous link from Jackrabbit Lane (Montana State Highway 85) easterly to North 7th Avenue. The segment of Baxter Lane in the study area is currently a two-lane, paved roadway. It has a paved surface width of approximately 37 feet, which includes a single travel lane in each direction, eastbound and westbound, as well as a bike lane and parking on the south side. The posted speed limit on Baxter Lane within the study area varies from 40 miles per hour (mph) from North 27th Avenue to approximately 670 feet east of North 27th Avenue. The posted speed limit then changes to 30 mph from that point east to North 19th Avenue. Study Area Intersections Tschache Lane & Proposed West Site Access As shown in Figure 2 on page 3, the west access to the site is proposed as a 26 foot wide City of Bozeman standard boulevard style drive approach. No modifications to Tschache Lane are initially proposed with the project. The proposed traffic control and intersection geometry is provided below: ❑ T-Intersection with Stop Control on the Southbound, Tschache Lane Apartments Approach ❑ Eastbound Approach(From the West)-(1) Left Turn/Through Lane ❑ Westbound Approach(From the East)-(1)Through/Right Turn Lane ❑ Southbound Approach(From the North)-(1) Left/Right Turn Lane ■ Proposed Queue Storage=±125 ft Tschache Lane & Proposed East Site Access Also shown in Figure 2 on page 3, the east access to the site is also proposed to be a T-intersection with stop control on the southbound approach, consisting of two 16 foot wide City of Bozeman boulevard style drive approaches separated by an 11 foot wide raised central median (face-of-curb to face-of-curb). Again, no modifications to Tschache Lane are initially proposed with the project at the east site access. The intersection geometry and traffic control are summarized below: ❑ T-Intersection with Stop Control on the Southbound,Tschache Lane Apartments Approach ❑ Eastbound Approach(From the West)-(1) Left Turn/Through Lane ❑ Westbound Approach(From the East)-(1)Through/Right Turn Lane ❑ Southbound Approach(From the North)-(1) Left/Right Turn Lane ■ Proposed Queue Storage=±100 ft 6 Morrison Traffic Impact Study Maierle orveyors•planners•scientists Bozeman West—Apartments I Bozeman, Gallatin County, Montana Tschache Lane & North 27th Avenue At the intersection of Tschache Lane and North 27th Avenue the east half of the collector roadway section for North 27th Avenue is in place; however, it is closed to traffic.

Counts were conducted during the weekday, AM and PM peak periods at the study area intersections on the dates noted below and are provided in Appendix B. Intersection turning movement count data were adjusted for seasonal variations. ❑ West Oak Street&North 27th Avenue Counts conducted by Sanderson Stewart on Tuesday, March 24, 2015 ❑ Tschache Lane&North 27th Avenue Counts conducted by Morrison-Maierle on Tuesday, March 29, 2016& Wednesday, March 30, 2016 ❑ Baxter Lane& North 27th Avenue Counts conducted by Morrison-Maierle on Thursday, March 31, 2016 ❑ North 19th Avenue&Baxter Lane Counts conducted by Sanderson Stewart on Tuesday,June 16, 2015 ❑ North 19th Avenue&Tschache Lane Counts conducted by Morrison-Maierle on Thursday,April 14, 2016 ❑ North 19th Avenue&West Oak Street Counts conducted by Sanderson Stewart on Tuesday, March 24, 2015 In order to reflect estimated current daily traffic volumes for 2017, it was necessary to adjust the data collected at the above intersections based on traffic volume growth trends within the study area. Evaluation of traffic volume trends on North 19th Avenue, Baxter Lane, and West Oak Street identified an average annual growth rate (AGR) of approximately 2.10% over the four-year period between 2011 and 2015 based on average daily traffic (ADT) data available from the Montana Department of Transportation. This traffic growth percentage was applied to the current daily traffic volumes to account for estimated traffic growth in the area from the time the data was collected at the above intersections to the year 2017. Estimated 2017 current daily traffic volumes are summarized in Figure 9 on the following page. Transit Service Streamline currently provides transit service to Belgrade, Bozeman, Four Corners, and MSU. This service is currently free for all passengers, which creates an incentive for transit ridership. Streamline offers one route that currently provides service along Tschache Lane within the study area - the Redline Downtown route (which primarily serves the Montana State University Strand Union, downtown Bozeman, the Gallatin Valley Mall, and Bozeman High School). Additionally, the Blueline Retail route (which primarily serves the Montana State University Strand Union and downtown Bozeman as well as the Bridger Peaks Town Center and Gallatin Center retail locations) to the east of the proposed Bozeman West - Apartments project on North 19th Avenue. Late night service is made available when Montana State University (MSU) is in session by Streamline Thursday through Saturday, with the Upstream route along North 19th Avenue within the study area. 13 Traffic Impact Study No iiiiiiiii Morrison Bozeman West-Apartments Bozeman, Gallatin County, Montana Maierle engineers surveyors Idnners s[ienli5f5 LEGEND WEEKDAY �'' '�-r •'•'�' XX AM PEAK HOUR p i (XX) WEEKDAY PM PEAK HOUR TURNING '� 73 931 102 At. 60 (167) h MOVEMENTS �., " .% y t (99) (916) (133) f 82 (204) A t, `� J �:� .` 64 (82) 11 3 4 8 't. 4 (7) ,-,i , 88 (110) —► \ (1) (1) (10) 201 (381) - 168 ( ) 43 393 65 0 + 7 �' 17 (72) 84 (89) '3, (122)(1127) (97) 3 (2) ? `1 �' 27 1033 19 10 (79) 392 (266) —0, 32 1 57 _ (59) (947) (8811) 10 (55) 33 (22) �, (41) (4) (60) _ ~� kv R�_ _- 3 4 41 (124) t 7 (40) --0---0- 43 450 23 PROJECT ��t.... 21. !t . 114 (81) �, (70) (1143) (54) LOCATION 2 .4 5 2 66 21 'L 9 (18) , Mj (5) (87) (11) 13 (28) a'.r - ._;, -gap ,1 l, 1 i ,t 2 (2) 1' 4 � r J 23 (13) —► 1 77 30 73 854 231 Z 93 (244) 10 (3) ', (7) (65) (17) (96) (866) (115,6) -0— 190 (470) C 116 (267) h 30 « 48 24 'L 29 (57) (55) (53) (16) -0— 236 (443) 1 4� 62 (183) .? 0 16 (84) 348 (268) —► 59 361 186 1 . 42 (60) 7• (121) (840) (235) t. 42 (25) 384 (254) 19 57 53 30 (17) (3) (35) (40) R ►' r , ►� L Figure 9: Estimated 2017 Current Daily Traffic 14 wi No Morrison Traffic Impact Study Maierle Bozeman West-Apartments I Bozeman, Gallatin County, Montana eng�me�ts�suarveyors•planners•scientists ie & bfsts Existing Trails & Sidewalks A gravel trail was constructed with the Baxter Springs Condominiums development that lies to the northwest of the proposed Bozeman West - Apartments project that provides a link to existing sidewalks on the south side of Baxter Lane. Additional gravel trails are located across Tschache Lane to the south through Rose Park as well as behind the existing retail shopping center between West Oak Street and Tschache Lane on the west side of North 19th Avenue. Sidewalks are located along both sides of Tschache Lane between North 19th Avenue and North 27th Avenue; however, there is a segment that is missing just west of the existing Home Depot store to the eastern boundary of the proposed Bozeman West-Apartments property. Proposed Trails & Sidewalks A connection to the existing gravel trail northwest of the Bozeman West - Apartments project is proposed to be completed as shown in Figure 2 on page 3. Sidewalks are also proposed throughout the development, providing connections between each of the apartment buildings as well as the community and maintenance buildings. As requested by the City of Bozeman, the missing sidewalk segment is included with the proposed improvements from the eastern boundary of the site to the west side of the existing Home Depot store on the north side of Tschache Lane. A mid-block pedestrian crossing has also been included south across Tschache Lane to Rose Park. Projected Traffic Site Traffic Dew ,+ M Tdp Cieneration Trip generation is a measure or forecast of the number of trips that begin or end at the development site. The traffic generated is a function of the extent and type of proposed development. This study utilized trip generation rates found in Trip Generation, 9th Edition published by the Institute of Transportation Engineers (ITE)for estimating average vehicle trip ends based on Land Use Code 220- Apartment. Trip ends are defined as a single or one-directional travel movement with either the origin or the destination of the trip inside the study site. For the apartment land use, dwelling units was used to estimate trip generation. Also, due to the proximity of the proposed development to Streamline transit routes, transit use is estimated to comprise a portion of the total trip generation. The estimated trip generation for the proposed Bozeman West - Apartments development is provided in Table 1 on the following page. Analyses are summarized in Appendix C. 15 Traffic Impact Study Morrison Bozeman West-Apartments I Bozeman, Gallatin County, Montana rle � Maie Table 1: Estimated Bozeman West-Apartments Trip Generation Summary Weekday,Average Weekday Trips Average Weekday, Average AM Peak Hour Trips PM Peak Hour Trips _Estimated Total Site Generated Trips(Apartment Units=Dwelling Units) I Apartment 216 716 716 F 1,432 22 88 i 0 88 48 336 Estimated Transit Use Trips 216 36 36rVer'licle nsit UseR5% Triped ction 72 1 I U 6 I I 7 I Estimated Net New Trips � = = As shown in Table 1 above, the proposed Bozeman West - Apartments development generates an estimated 1,432 average weekday trips as well as average weekday, AM and PM peak hour trips of 110 and 136 vehicles, respectively. Additionally, the estimated traffic generation shown in Table 1 above is comprised of primary purpose trips for both vehicular traffic and estimated transit use. Primary purpose trips are those where the site is the primary origin or destination, which result in new trips on the roadway system. Development Trip Distribution Trip distribution and assignment is the process of identifying the probable destinations, directions, and traffic routes that development related traffic will likely affect. The estimated traffic generated by the development must be distributed and assigned in order to analyze the impacts on the roadway system and intersections within the study area. 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, which bases the trip distribution on existing travel patterns in the area and the area of influence method that assumes trips will originate or terminate within a given area. The primary trip distribution for the proposed Tschache Lane Apartments is shown in Figure 3 on the following page. Modal Split Modal split refers to how the total number of person trips are divided amongst the various means of travel such as automobile (both single occupant and carpool), walking, biking, or transit. In most instances, the automobile is the primary means of travel. However, the other means of travel may account for a portion of the trips generated by a site. 16 W �.1 Q Q 10 1 x Z • � _ ,iBAXTER LN fl _ Ft PROJECT LOCATION 1 ♦1 t iF, r l ' - TSCHACHE LN isub . l= n , Q a) Z z ws,. .t w OAK ST ftLll All LEGEND it I A PRIMARY TRIP DISTRIBUTION PERCENTAGE Traffic Impact Study No Morrison Bozeman West-A arfrnents I Bozeman, Gallatin County, Montana Malerle Vehicular and transit trips have been estimated for the proposed development. Bicycling and pedestrian trips are not assumed to comprise a significant portion of site related trips. Vehicular trips can be further identified as primary purpose, pass-by, diverted, and internal trips. Primary purpose trips have been defined previously. Pass-by trips are those that result from traffic passing on an adjacent roadway that enters the site and then exits, resuming travel in the same direction. As defined in Transportation and Land Development, 2nd Edition (Stover and Koepke, 2002), diverted trips are those that enter and exit a site that are diverted from a route other than the one to which the site has access. These can be both trips diverted from an adjacent route as well as those diverted from another route not adjacent to the site. Internal trips are those that begin and end within the site but do not affect the adjacent roadways. Pass-by, diverted, and internal trips are not estimated to constitute a significant portion of site related vehicular traffic and have therefore been excluded from the analyses. Trip Assignment The assignment of development related 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 along the roadway system and at area intersections. At a minimum, trip assignment must also consider route choice, how the existing transportation system functions, and travel times to and from the site. The resulting traffic assignment for the proposed Bozeman West - Apartments development at the study area intersections is shown in Figure 11 on the following page. The traffic assignment at the proposed site accesses is shown in Figure 12 on page 20. Parking Demand Off-street parking requirements are defined in the City of Bozeman's Unified Development Code (UDC). These requirements define the required minimum number of vehicle and bicycle parking spaces. The off-street parking requirements for the proposed development are shown in Table 2 below.

For a facility with 301 to 400 parking spaces, a minimum of eight of those spaces must be accessible. Additionally, one of the eight accessible spaces must be van accessible. Additionally, per Section 38.25.040.1.b.(4) of the City of Bozeman UDC, "A residential development subject to site plan review may take a ten percent reduction in required parking spaces where the development is within 800 feet of a developed and serviced transit stop. For the purpose of this subsection a transit stop is eligible when it has a shelter installed which meets the standards of and is approved by the transit provider, and service is provided on not less than an hourly schedule a minimum of five days per week." Non-Site Traffic Method of Projection In order to more accurately reflect the potential impacts from development generated traffic it is necessary to develop an estimate of non-site related traffic growth during the analysis period. Three primary means are typically used to estimate growth of non-site generated traffic, including the build-up method, the use of transportation plans or models, as well as the trends or growth rate method. The build-up method takes into account traffic growth due to approved or anticipated to be approved developments in the study area. Transportation plans or models typically provide estimates for traffic volumes for approximately 20 years into the future. The trends or growth rate method involves evaluating the historic traffic growth rates within a study area. The underlying assumption with this method is that historic growth trends will remain approximately the same and continue in the future. Estimated Volumes Estimated background traffic volumes for the 2020 development horizon were established by applying growth projections on the adjacent transportation network evaluated as a part of this study. In determining average annual growth rates (AAGR) in traffic volumes for the transportation network, data was evaluated for growth trends from the year 2006 to 2016. The estimated AAGR rates determined between those years are listed below and were applied to estimated 2017 daily traffic within the project study area. Estimated 2020 background traffic volumes are shown Figure 13 on the following page. ❑ Tschache Lane AAGR=±3.08% ❑ North 19th Avenue AAGR=±1.19% ❑ North 27th Avenue AAGR=±3.08% ❑ West Oak Street at ❑ Baxter Lane AAGR=±3.08% North 19th Avenue AAGR=±5.24% ❑ Thomas Drive AAGR=±6.32% ❑ West Oak Street at North 27th Avenue AAGR=±7.74% 21 Traffic Impact Study Morrison Bozeman West-Apartments Bozeman, Gallatin County, Montana Malerle LEGEND Xx WEEKDAY `r1�i is .._: • AM PEAK HOUR r (XX) WEEKDAYi PM PEAK HOUR EN TURNING ,�• �y! 80 976 112 'L 66 (183) h MOVEMENTS 1 Ts (108) (952) (146) f. 90 (223) 70 (90) 96 (12 4 5 10 'L 5 O � h (1) (1) (12) 220 (417) r 184 (177) —► 47 414 71 0 + 7 19 (79) 92 (97) 7• (134)(1197)(106) r._r 4 (2) h ,.ml , 30 1087 21 ''C 11 (87) 429 (291) —► 35 1 62 _ 36 (24) �, (45) (5) (66) ^r 0 12 (99) - 3 5 �R 4 45 (136) J h f t+ 8 (44) —► 47 476 25 i PROJECT .L J LOCATION 125 (89) '3, (77) (1214) (59) 2 z g :--. 2 72 23 'L 10 (20) (5) (95) (12) -0— 14 (31) y r 13 (47) � 2 2 (2) 1' ; 6 i 25 (14) 1 84 33 r 11 (3) (8) (71) (19) ) 80 891 253 102 (267) ''C Z (105) (897) (171) 208 (515) f i A. 127 (292) 33 53 26 Z 32 (62) 6 (60) (58) (18) 295 (554) 72 (213) 1` +j ,� 7 �- 16 (84) 406 (312) —► 74 374 204 49 (70) ', (141) (870) (257) 480 (318) --► 19 62 53 30 (17) �, (3) (38) (40) fir'rig `;'r •t Is or- Figure 13: Estimated 2020 Background Traffic 22 Morrison Traffic Impact Study M i e r l a Bozeman West—Apartments I Bozeman y engineers•surveyors planners•scientists , Gallatin County, Total Traffic Site-generated traffic from the proposed Bozeman West- Apartments development was combined with the estimated 2020 background traffic volumes to establish the estimated 2020 total traffic volumes that were used in the impact analyses. Estimated 2020 total traffic at the study area intersections is shown in Figure 14 on the following page. The estimated 2020 total traffic at the proposed site accesses is shown in Figure 15 on page 25. ,Transportation Methodologies This section documents the methodologies and assumptions used to conduct the traffic impact analyses for the proposed Bozeman West - Apartments. Study methodology and analyses are based on ITE's Recommended Practices for Transportation Impact Analyses for Site Development. These analyses are used to determine the project's conformance with City of Bozeman policies and evaluate whether the proposed development's impacts are perceptible to the average driver. Shidy Scenades This study presents analyses of the following scenarios: ❑ Existing Conditions ❑ Estimated 2020 Background Traffic ❑ Estimated 2020 Total Traffic Analysis Methodologies Transportation system operating conditions are typically described in terms of "level of service". Level of service (LOS) is the performance measure used 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, which represents the most favorable to the least favorable operating conditions. Level of service for intersections is determined by control delay. Control delay 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. Appendix A lists the delay/LOS criteria listed in the Highway Capacity Manual 2010 (HCM) published by the Transportation Research Board (TRB) for signalized and unsignalized intersections. 23 Traffic Impact Study ■■ Morrison Bozeman West-Apartments Bozeman, Gallatin County, Montana •�„Malerle LEGEND r WEEKDAY �.. ,>t•, \� ' XX AM PEAK HOUR WEEKDAY ` (XX) PM PEAK HOUR NA D �' TURNING ,�� ':- f , ' .�t 80 981 112 66 (183) h MOVEMENTS �. �- (108) (972) (114,6) 90 (223) 77 (117) 99 (121) '` �. 4 5 10.

These analyses are based on HCM analysis methodology for evaluating signalized intersections, which is based on the 'operational analysis" procedure. This technique utilizes 1,900 passenger cars per hour of green per lane (pcphgpl) as the maximum saturation flow of a single lane at an intersection. This saturation flow rate is adjusted to account for lane width, on-street parking, conflicting pedestrians, traffic composition, and shared lane movements. Average delay is calculated by taking a volume- weighted average of all the delays for all vehicles entering the intersection. Two-Way Stop-Controlled(TWSC) Intersections Two-way stop-controlled (TWSC) intersection capacity and level of service analyses were performed using Highway Capacity Software 2010 TWSC Version 6.80 (HCS) developed and maintained by the McTrans Center at the University of Florida. TWSC intersection analyses are based on Chapter 19 of the HCM. 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 "worst approach" are reported. Level of service is not defined for the intersection as a whole. All-Way Stop-Controlled(AWSC) Intersections All-way stop-controlled (AWSC) intersection capacity and level of service analyses were also performed using HCS. AWSC intersection analyses are based on Chapter 20 of the HCM. The HCM methodology for evaluating AWSC intersections is a function of traffic and conditions on each of the approaches and the presence of bicyclists and pedestrians. Average control delay and LOS are reported. Level of service is also defined for the intersection as a whole. Capacity & Level of Service Capacity and level of service analyses were performed for the study area intersections for estimated 2017 current daily traffic volumes (shown in Figure 9 on page 14), estimated 2020 background traffic volumes (shown in Figure 13 on page 22), and estimated 2020 total traffic volumes (shown in Figure 14 on page 24). Evaluations were performed using the existing geometry and traffic control at each of the study area intersections, with the exception of the proposed site accesses, to determine estimated capacity and level of service. The analyses are summarized in the tables on the following pages and detailed results are included in Appendix D. 26 No Morrison Traffic Impact Study Mal, "si Plu�i� Bozeman West—Apartments I Bozeman, Gallatin County, Montana engmecn funeou es irnnat Table 3:Weekday,AM Peak Hour Intersection Operations Summary for West Oak Street&North 27th Avenue Performance Measure LOS A A A A C B D C Estimated 2017 Current Daily Traffic Delay Conditions (slveh) Two-Way Volume to Capacity Stop Control Ratio(vlc) [LO4 -

The UDC additionally states, "A development shall be approved only if the LOS requirements are met in the design year, which shall be a minimum of 15 years following the development application review or construction of mitigation measures if mitigation measures are required to maintain LOS. Intersections shall have a minimum acceptable LOS of"C"for the intersection as a whole." Improvements to Accommodate Estimated 2017 Current Daily Traffic For estimated 2017 current daily traffic volumes, two intersections were identified that were estimated to experience substandard levels of service -West Oak Street and North 27th Avenue as well as West Oak Street and North 19th Avenue. West Oak Street&Moft Av nnue As shown in in Table 3 on page 27 and Table 4 on page 28, southbound left turn movements at the intersection of West Oak Street and North 27th Avenue were estimated to be operating at a substandard level of service during both the weekday, AM and PM peak hours. This intersection was included in the Oak Street Improvements Pre-Design Report prepared by Sanderson Stewart (February 2016). This study identified two alternatives for improvements at the intersection of West Oak Street and North 27th Avenue. One alternative included installation of a traffic signal with some geometric modifications at the intersection. The other included installation of a multilane roundabout. Improvements to the intersection of West Oak Street and North 27th Avenue are included in the City of Bozeman's Fiscal Years 2017-2021 Capital Improvements Program (Adopted December 2015). These improvements are identified as including a traffic signal, roundabout, or other adequate traffic control device when warrants are met. Brief analyses of signal warrant criteria for estimated 2017 current daily traffic, 2020 background traffic, and 2020 total traffic volumes revealed that the minor street volumes (North 27th Avenue) at the intersection of West Oak Street and North 27th Avenue are not estimated to satisfy minimum criteria for installation of a traffic signal as found in the Manual on Uniform Traffic Control Devices, 2009 Edition (United States Department of Transportation - Federal Highway Administration, May 2012) at this time nor are they near meeting signal warrant criteria. 38 �� Morrison Traffic Impact Study Maierle Bozeman West-Apartments I Bozeman, Gallatin County, Montana figlllfflS luf'j UIS ,IA!!I!<!1 1(!f!IS!> An interim measure for mitigating traffic operational issues at an intersection prior to minimum criteria for installation of a traffic being met typically may include installation of all-way stop control (AWSC). Capacity and level of service analyses were performed for the intersection of West Oak Street and North 27th Avenue under AWSC for estimated 2017 current daily traffic volumes. The analyses are summarized in the Table 17 on the following page with detailed results included in Appendix E-1. North 19th Avenue & West Oak Street As shown in in Table 14 on page 36, the intersection of North 19th Avenue and West Oak Street as a whole is estimated to operate at LOS D for the weekday, PM peak hour. However, the average delay for the intersection is marginally over the 35 seconds boundary between LOS C and D; therefore, because of this and that the weekday, AM peak hour is estimated to be operating within acceptable levels of service no additional improvements or mitigation for estimated 2017 current daily traffic volumes is deemed necessary at this time. Improvements to Accommodate Estimated 2020 Background Traffic For estimated 2020 background traffic volumes, three intersections were identified as being outside level of service standards - 1)West Oak Street and North 27th Avenue; 2) Baxter Lane and North 27th Avenue; and 3)West Oak Street and North 19th Avenue. West Oak Street & North 27th Avenue Table 3 on page 27 and Table 4 on page 28 both show northbound left-through and southbound left turn movements at the intersection of West Oak Street and North 27th Avenue estimated to operate at a substandard level of service during both the weekday, AM and PM peak hours. Additionally, southbound through-right movements are projected to operate at LOS D during the weekday, PM peak hour. Applying the interim measure of AWSC utilized for mitigating estimated 2017 current daily traffic volumes, capacity and level of service analyses were performed for the intersection of West Oak Street and North 27th Avenue for estimated 2020 background traffic volumes (shown in Figure 13 on page 22). The analyses are summarized in Table 18 on page 41 with detailed results included in Appendix E-2. Baxter Lane & North 27th Avenue As shown in in Table 8 on page 30, southbound movements at the intersection of Baxter Lane and North 27th Avenue are estimated to operate at LOS D during the weekday, PM peak hour.

This intersection was also included in the Oak Street Improvements Pre- Design Report. This study recommended improvements at the intersection, including the addition of an eastbound through lane as well as a dedicated right turn lane. Capacity and level of service analyses were performed for the intersection of North 19th Avenue and West Oak Street for estimated 2020 background traffic volumes (shown in Figure 13 on page 22). The analyses are summarized in Table 19 on the following page 43with detailed results included in Appendix E-2. Improvements to Accommodate Estimated 2020 Total Traffic For estimated 2020 total traffic volumes, the same three intersections were identified as being outside level of service standards — 1)West Oak Street and North 27th Avenue; 2) Baxter Lane and North 27th Avenue; and 3)West Oak Street and North 19th Avenue. West Oak Street & North 27th Avenue Similar to estimated 2020 background traffic volumes, Table 3 on page 27 and Table 4 on page 28 both show the same movements operating at substandard levels of service under estimated 2020 total traffic volumes. As before, AWSC was evaluated for mitigating operational deficiencies for the intersection of West Oak Street and North 27th Avenue for estimated 2020 total traffic volumes (shown in Figure 14 on page 24). The analyses are summarized in Table 20 on page 44 with detailed results included in Appendix E-3. Baxter Lane & North 27th Avenue As shown in in Table 8 on page 30, there is very little change to average vehicle delays for southbound movements at the intersection of Baxter Lane and North 27th Avenue with the addition of traffic from the proposed Bozeman West - Apartments project. Those movements are again estimated to operate at LOS D during the weekday, PM peak hour. As noted previously, the slightly longer average vehicle delays affect a limited number of vehicles, resulting in a minor benefit being gained through mitigation of substandard traffic operations for that approach. Therefore, improvements to address the level of service for estimated 2020 total traffic volumes on the southbound, Thomas Drive approach at the intersection have not been evaluated. 42 ..

Each has adequate capacity to meet traffic demands. North 19th Avenue and its intersections with Tschache Lane and West Oak Street were identified to have excessive vehicle queues through the capacity and level of service analyses. Southbound left turn movements at the intersection of West Oak Street and North 27th Avenue were assessed to operate at LOS D and E during the weekday, AM and PM peak hours, respectively, for estimated 2017 current daily traffic volumes. No vehicle queues are estimated to exceed the available storage on each of the approaches for either analysis period. The intersection of North 19th Avenue and West Oak Street as a whole was identified as operating at LOS D for estimated 2017 current daily traffic volumes for the weekday, PM peak hour. However, overall average vehicle delay for the intersection was found to be at the boundary between LOS C and D that occurs at 35 seconds per the HCM. At the intersection of North 19th Avenue and Tschache Lane, eastbound left turns as well as westbound movements were estimated to have vehicle queues that exceed the available storage on those approaches during the weekday, PM peak hour. For the intersection of North 19th Avenue and West Oak Street, eastbound through-right turn movements are estimated to have vehicle queues in excess of the available storage length during the weekday, AM peak hour. During the weekday, PM peak hour eastbound movements as well as westbound left turns were identified to experience excessive vehicle queues. Traffic Operations for Estimated 2020 Background Traffic With projected traffic growth in the area, Baxter Lane and North 27th Avenue was the only additional intersection projected to operate outside of acceptable levels of service for estimated 2020 background traffic volumes. Continuing from the 2017 operational analyses, North 19th Avenue and its intersections with Tschache Lane and West Oak Street were identified to have excessive vehicle queues. 46 .. Morrison Traffic Impact Study Iiiiiiiii M s-i e r l e engineers•surveyors•planners�scientists Bozeman West-Apartments I Bozeman, Gallatin County, Montana Southbound left turn movements were forecast to experience a decline in level of service from LOS D to E during the weekday, AM peak hour for estimated 2020 background traffic volumes at the intersection of West Oak Street and North 27th Avenue. Those movements are also estimated to decline from LOS E to F during the weekday, PM peak hour while the through-right movements decline to LOS D during that analysis period. Additionally, northbound left-through movements were predicted to experience substandard levels of service during both analysis periods - LOS D (AM peak) and LOS E (PM peak). No excessive vehicle queues are estimated for either analysis period. The southbound approach at the intersection of Baxter Lane and North 27th Avenue was determined to operate at LOS D during the weekday, PM peak hour for estimated 2020 background traffic volumes. However, there are only a total of 14 estimated vehicles (approximately one vehicle every four minutes) for that analysis period. No additional operational deficiencies or excessive vehicle queues were noted during either the weekday, AM or PM peak hours. No declines in level of service were estimated for the intersection of North 19th Avenue and West Oak Street as a whole for estimated 2020 background traffic volumes. Average vehicle delay was found to increase from 35 to 38.7 seconds during the weekday, PM peak hour. During the weekday, AM peak hour northbound right turns as well as southbound left turn movements may see a decline in level of service from LOS B to LOS C; however, this is still within acceptable standards. No changes in level of service were shown for the weekday, PM peak hour. No additional movements were anticipated to have excessive queuing beyond those identified for the estimated 2017 current daily traffic analyses. In addition to the movements identified in the 2017 analyses, eastbound through-right turn movements at the intersection of North 19th Avenue and Tschache Lane were projected to have vehicle queues exceeding the available storage on that approach during the weekday, PM peak hour for estimated 2020 background traffic volumes. Traffic Operations for Estimated 2020 Total Traffic No additional intersections were projected to operate outside of acceptable levels of service with the addition of estimated traffic from the proposed Bozeman West - Apartments development through the estimated 2020 total traffic operational analyses. The remaining intersections within the study area operate within acceptable levels of service during both the weekday, AM and PM peak hours. Each has adequate capacity to meet traffic demands. Continuing from the 2020 background traffic operational analyses, North 19th Avenue and its intersections with Tschache Lane and West Oak Street were identified to have excessive vehicle queues. 47 Traffic Impact Study ME Morrison Bozeman West-Apartments I Bozeman, Gallatin County, Montana mill Maierle At the intersection of North 19th Avenue and Baxter Lane, the intersection as a whole is estimated to operate within acceptable levels of service for the weekday, AM and PM peak hours. However, during the weekday, PM peak hour estimated vehicle queues may exceed the available storage for westbound left turns, northbound through-right, and southbound through-right movements. Level of service as a whole during the weekday, AM peak hour was estimated to decline to LOS D at the intersection of North 19th Avenue and West Oak Street for estimated 2020 background traffic volumes. No changes were shown for the weekday, PM peak hour, nor was there an increase in estimated average vehicle delay for that analysis period. Again, no additional movements were anticipated to have excessive queuing beyond those identified for the estimated 2017 current daily traffic analyses. Site Accessibility The proposed site accesses to Tschache Lane were both found to operate within acceptable levels of service for estimated 2020 total traffic volumes, having adequate reserve capacity and included queue storage to absorb any impacts resulting from continued traffic growth on Tschache Lane beyond the analysis timeframe include with this study. Parking As shown in Table 2 on page 18, there are a minimum 377 required off-street vehicle parking spaces and 38 bicycle spaces for the proposed Bozeman West - Apartments development. The site layout shown in Figure 2 on page 3 has a total of 380 vehicle and 42 bicycle parking spaces for a total of 422 spaces. As currently proposed, the site has an adequate number of vehicle parking spaces as well as an excess number of bicycle parking spaces. Transit Service Transit service is presently available within the study area and route stops are provided on Tschache Lane during weekdays within relatively close proximity to the proposed Bozeman West - Apartments development at the intersections of North 27th Avenue as well as North 19th Avenue. Pullouts are not currently provided at either location for transit vehicles. Furthermore, shelters are not currently available within the study area for transit riders at route stop locations. 48 Morrison Traffic Impact Study Maierle Bozeman West-Apartments I Bozeman, Gallatin County, Montana Pedestrian & Bicyclist Connectivity A gravel trail links the Bozeman West - Apartments project to existing sidewalks on the south side of Baxter Lane with a connection proposed to Tschache Lane. Additional gravel trails are located across Tschache Lane to the south through Rose Park as well as behind the existing retail shopping center between West Oak Street and Tschache Lane on the west side of North 19th Avenue. As requested by the City of Bozeman, a mid-block pedestrian crossing has been aligned with the proposed gravel trail through the western portion of the Bozeman West -Apartments development to provide access across Tschache Lane to Rose Park. Sidewalks are located along both sides of Tschache Lane between North 19th Avenue and North 27th Avenue; however, there is a segment that is missing just west of the existing Home Depot store to the eastern boundary of the proposed Bozeman West - Apartments property. The missing sidewalk segment is included with the proposed improvements for the development. Sidewalks are also proposed throughout the development, providing connections between each of the apartment buildings as well as the community and maintenance buildings. Need for Any Improvements Site Accessibility As the proposed accesses serving the Tschache Lane Apartments development are estimated to function with acceptable capacity and within satisfactory levels of service for estimated 2020 total traffic volumes, no additional improvement needs were identified as a part of this study. Additionally, the accesses are projected to have adequate reserve capacity as well as included queue storage to absorb any impacts resulting from continued traffic growth on Tschache Lane beyond the analysis timeframe include with this study. Parking Because the proposed site is deficient six vehicle parking spaces, additional off-street parking spaces would need to be added to the proposed layout or an allowable reduction may be requested from the City of Bozeman. The inclusion of a shelter along Redline Downtown route as approved by Streamline transit near the present stop at the intersection of Tschache Lane and North 27th Avenue would be within the 800 foot maximum distance allowed for a transit related parking reduction. 49 Traffic Impact Study No Morrison Bozeman West-Apartments I Bozeman, Gallatin County, Montana Maierle r.rrrreHS .rymt I+I.nri P+. rr.lif. Traffic Operations Through the operational analyses, two intersections were found to require mitigation due to substandard levels of service for the scenarios included as a part of this study -West Oak Street and its intersections with North 27th Avenue and North 19th Avenue. Southbound movements at the intersection of Baxter Lane and North 27th Avenue / Thomas Drive were projected to experience substandard levels of service during the weekday, PM peak with continued traffic growth in the area. However, the limited traffic volume on that approach did not justify mitigation within the timeframes evaluated as a part of this study. Analysis of AWSC at the intersection of West Oak Street and North 27th Avenue identified that the substandard levels of service could be mitigated for estimated 2020 total traffic volumes with modifications to existing pavement markings on the eastbound approach, replacing the dedicated left turn lane with a shared left-through lane. This improvement would be an interim measure until such time the intersection meets warrants for installation of a traffic signal, roundabout, or other adequate traffic control device. At the intersection of North 19th Avenue and West Oak Street, the inclusion of the improvements recommended by the Oak Street Improvements Pre-Design Report prepared by Sanderson Stewart, an additional eastbound through lane as well as a dedicated right turn lane, was forecast to mitigate the overall level of service through the estimated 2020 development horizon. Conclusions & Recommendations The estimated 2020 total traffic volumes utilized in the analyses for the study area include the projected traffic from the proposed Bozeman West - Apartments. No impacts to study area intersections directly resulting from traffic generated by the proposed project were identified that would require mitigation in association with its development. Impacts resulting from traffic generated by the proposed development can be accommodated by the existing transportation system with the recommendations included as a part of this study. 61ite Accessibility Traffic Operations The proposed accesses to/from the Bozeman West - Apartments to Tschache Lane are projected to operate acceptably as single lane approaches. Additionally, no adverse impacts were identified to traffic operations for through traffic on Tschache Lane as a result of development related traffic; therefore, auxiliary lanes would not be required to mitigate any substandard traffic operations. 50 No Morrison Traffic Impact Study IIII� M a i e r l e Bozeman West-Apartments 1 Bozeman, Gallatin County, Montana lI+Ij IIIPIt »IrCf414 I:Idnnl•I4 tl Illl lr}74 Geometrics & Sight Distance ❑ Driveways should be installed in accordance with the City of Bozeman's design standards. ❑ Driveways and internal drive aisles need to be designed for the appropriate vehicles that may access the facility, including emergency and solid waste vehicles. ❑ 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 American Association of State Highway and Transportation Officials(AASHTO)standards. ❑ Stop control should be installed on the southbound site approaches at their intersection with Tschache Lane.

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 particular 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 :510 seconds LOS A—Little or no delay 10.1 —15.0 seconds LOS B—Short traffic delay 15.1—25.0 seconds LOS C—Average traffic delay 25.1 —35.0 seconds LOS D—Long traffic delays 35.1—50.0 seconds LOS E—Very long traffic delays >50.1 seconds LOS F—When the demand exceeds the capacity of the lane,extreme delays will be encountered and queuing may cause severe congestion to the intersection.

Delay is a measure of driver and/or passenger discomfort, frustration, fuel consumption, and lost travel time. The level of service criteria for signalized intersections is presented in Table A-2 below. Table A-2: Level of Service Criteria for Signalized Intersections Control Stopped Dela Per Vehicle Level of Service(LOS)Characteristics s 10 seconds LOS A—Operations with very low delay.This occurs when progression is extremely favorable,and most vehicles do not stop at all.Short cycle lengths may also contribute to low delay. 10.1—20.0 seconds LOS B—Operations with generally good progression and/or short cycle lengths.More vehicles stop than for LOS A,causing higher levels of average delay. LOS C—Operations with higher delays,which may result from fair progression and/or longer cycle 20.1—35.0 seconds lengths. Individual cycle failures may begin to appear at this level.The number of vehicles stopping is significant at this level,although many still pass through the intersection without stopping. LOS D—Operations with high delay,resulting from some combination of unfavorable progression, 35.1—55.0 seconds long cycle lengths,or high volumes.The influence of congestion becomes more noticeable,and individual cycle failures are noticeable. 55.1—80.0 seconds LOS E—Considered being the limit of acceptable delay. Individual cycle failures are frequent occurrences. LOS F—A condition of excessively high delay,considered unacceptable to most drivers.This >80.1 seconds condition often occurs when arrival flow rates exceed the capacity of the intersection.Poor progression and long cycle lengths may also be major contributing causes to such delay. Source: Highway Capacity Manual 2010(Transportation Research Board,2000) of • The City of Bozeman Unified Development Ordinance (UDO) identifies specific standards for transportation facilities and access.The standards pertaining to this study are identified in the paragraphs that follow. Traffic Progression Section 38.24.060.B.3 of the UDO conveys specific requirements for the spacing of potential intersections with traffic signals. This Section states the following: "Traffic progression will be of paramount importance.Consequently,all potential intersections with signals will be placed on quarter-mile points unless otherwise approved by the review authority."

Morrison Traffic Impact Study iiiiiiiii Ms-i e r I e engineers•surveyors•planners.scientists Tschache Lane West Apartments I Bozeman, Gallatin County, Montana Level of Service Standards Level of service standards for arterial and collector streets as well as intersections with arterial and collector streets are stated in Section 38.24.060.B.4 of the LIDO. Those standards are as follows: All arterial and collector streets and intersections with arterial and collector streets shall operate at a minimum level of service "C" unless specifically exempted by this subsection. Level of service (LOS) values shall be determined by using the methods defined by the most recent edition of the Highway Capacity Manual. A development shall be approved only if the LOS requirements are met in the design year,which shall be a minimum of 15 years following the development application review or construction of mitigation measures if mitigation measures are required to maintain LOS. Intersections shall have a minimum acceptable LOS of "Ct for the intersection as a whole. a. Exception: If an intersection within the area required to be studied by section 38.41.060.A.12 does not meet LOS"Cr and the intersection has been fully constructed to its maximum lane and turning movement capacity,then an LOS of less than"C" is acceptable. b. Exception:The review authority may accept an LOS of less than"C"at a specific intersection if: (1) A variance to allow a lesser LOS was approved not more than two years prior to the date an application for development being reviewed is determined to be adequate for review; (2) The request was made in writing with the application; and (3) The circumstances are in the professional judgment of the review authority substantially the same as when the variance was granted.
