Marvin & Associates was retained by Walter Wolf to prepare the TIS in accordance with City of Bozeman subdivision development ordinances. The primary purposes of this study were to address specific traffic impacts related to development of Flanders Mill Subdivision and to provide recommendations regarding the mitigation of any identified impacts. Having reviewed the proposed land use development plan, Marvin & Associates completed an extensive analysis of existing conditions, addressed trip generation, trip distribution and traffic assignment, and evaluated the resulting arterial and intersection capacity impacts, before making recommendations regarding the mitigation of impacts. The study methodology and analysis procedures used in this study employed the most contemporary of analysis techniques, using nationally accepted standards in the areas of site development and transportation impact assessment. Recommendations made within this report are based upon those standards and the professional judgment of the author. SITE LOCATION & DESCRIPTION The Flanders Mill Subdivision is bounded by Flanders Mills Road, on the west; Ferguson Avenue, on the east; Baxter Lane, on the north; and a parcel of property that fronts on Durston Road, on the south (see Figure 1). The preliminary plat for Flanders Mill Subdivision proposes the development of 284 single family residential lots and a cluster of lots with 112 multi-family residential units. Flanders Mill Subdivision TIS Page 2 Flanders Mill Subdivision TIS Page 3 Access to Flanders Mill would involve 15 local street intersections along the three arterial streets boarding the subdivision. The single access to Baxter lane would align with Riatta Street in the Baxter Meadows Subdivision. Four local streets intersecting Ferguson Avenue, south of Oak Street, would align with proposed subdivision streets. In addition to subdivision street accesses, the proposed subdivision improvements would extend two arterial streets through and alongside the subdivision. Oak Street would be extended from Ferguson Avenue west to a new intersection with Flanders Mill Road. Ferguson Avenue would be extended south from Baxter Lane to Oak Street. These two arterial roadway extensions would complete the arterial grid in this portion of Bozeman and would result in a significant redistribution of existing traffic flow. The redistribution of traffic is a key element in the TIS and is addressed within this report. EXISTING CONDITIONS Streets & Intersections Adjacent and potentially impacted public streets would include: Baxter Lane, Davis Lane, Ferguson Avenue, Flanders Mill Road, Harper Puckett Road, Oak Street, Durston Road, Cottonwood Road, and West Babcock Street. Various other area local streets within a one mile radius of the site could also potentially realize minor impacts. Eleven existing intersections would have the greatest potential for impacts. All of those intersections along with two new arterial road intersections have been analyzed within this study. Baxter Lane is an east-west oriented minor arterial that begins at Jackrabbit Lane, north of the Four Corners area and ends at N. 7th Avenue in Bozeman. Baxter lane has variable pavement widths and varying speed zones along its length. Between N. 19th Avenue and N. 7th Avenue, Baxter is classified by the State as Urban Route 1218. Flanders Mill Subdivision TIS Page 4 Davis Lane is a north-south oriented minor arterial that currently extends south from Valley Center Road to Oak Street. Davis Lane was extended one mile south of Baxter to connect Baxter Lane with Oak Street in the recent past. Ferguson Avenue is a north-south oriented collector street, which extends north from Huffine Lane to Oak Street and from Baxter Lane north through the Baxter Measows Subdivision. The existing intersection of Ferguson Avenue and oak Street operates as a 90 degree curve, with only northbound and westbound approaches. Ferguson will be extended south from Baxter as a part of Flanders Mill Subdivision Development. Flanders Mill Road is a paved county road that extends south from Baxter Lane to Durston Road and functions as a collector or minor arterial street due to the lack of north-south connector roadways. A substantial amount of traffic utilizes Flanders Mill Road as a shortcut connection between Baxter and Durston. Harper Puckett Road is a local county road that extends south from the eastern terminus of Cameron Bridge Road, near I-90, to intersect with Valley Center Road. It then continues south, winding some to the east and coming to a “T” intersection with Baxter Lane at the west edge of the Flanders Mill Property. Durston Road is a principal arterial road, which extends from Love Lane, west of Bozeman, through the center of Bozeman to North Rouse, a distance of approximately 5 miles. Durston Road varies in width along its length and at its numerous intersections within the urban area. Oak Street is a principal street that currently extends from Ferguson Avenue to North Rouse, a distance of approximately 3 miles. It has been constructed to principal arterial standards within the past 10 years and has various widths with multiple lanes and wide medians west of N 19th Avenue. Flanders Mill Subdivision TIS Page 5 West Babcock is an arterial street that extends from a point just west of Cottonwood Road to Main Street (Huffine Lane), a distance of approximately 2 miles. West Babcock is a current standard two-lane roadway with bike lanes along most of its length. Cottonwood Road is a north-south arterial roadway that extends from the foothills south of the Bozeman Valley to a point just north of Durston Road, a distance in excess of 8 miles. It currently defines the western boundary of dense urban development within Bozeman. It is a two lane roadway along most of its length and has curb and gutter sections north of Huffine Lane. At its intersection with West Babcock, the intersection has raised medians and auxiliary turn lanes. The majority of potentially impacted intersections are currently two-way stop-controlled. The intersections of Davis and Baxter and Durston and Ferguson are all-way stop controlled. The intersection of Ferguson and Baxter is controlled by a single lane roundabout. Figure 2, on the following page, illustrate the lane configurations and traffic control devices that exist at all of the potentially impacted intersections. The intersections created by the development’s roadway extensions would have lane configurations and controls subject to current standards and potential operational requirements evaluated within this study. Flanders Mill Subdivision TIS Page 6 Flanders Mill Subdivision TIS Page 7 Traffic Volumes Twenty-four hour automatic traffic counts were taken in October 2012 and August of 2013 at nine locations within the area surrounding the proposed project site. The counts provided hourly variations, which were used to determine peak hours and provide base volumes for turning movement projections. Summaries of the counts can be found be Appendix A of this report. The daily peak for area traffic was found to occur between 4:30 and 5:30 p.m. Figure 3 on the following page presents existing (2013) pm peak hour turning movement volumes at potentially impacted intersections. Street segment average daily traffic (ADT) volumes are also depicted in the figure. ADTs were calculated based upon both twenty-four hour and peak hour turning movement count data. Since the majority of pm turning movement counts were taken in August and September of 2013, it can be assumed that the peak hour counts replicate design hour counts, which would be slightly higher than volumes during the winter months. Pedestrian activity was found to be mostly insubstantial at all of the intersections and therefore was not indicated on the turning movement diagrams. Turning movement counts at the intersection of Flanders Mill Road and Durston were taken when the new Meadowlark Elementary School was having its open house and there were numerous pedestrian crossings (both children and adults) which would not be typical during the normal peak pm hour. Observations within the influence area of the project indicated that heavy truck and bicycle traffic, while present at all of the intersection, was not a significant determinant in the analysis of overall operations. Flanders Mill Subdivision TIS Page 8 Flanders Mill Subdivision TIS Page 9 Capacity Peak pm hour existing capacity calculations were completed for the eleven existing potentially impacted intersections using the HCS 2010 and SIDRA software packages. Table 1, on the following page, summarizes the results of the capacity calculations. Measures in the table include control delay (seconds/vehicle), level of service (LOS), volume-to-capacity (v/c) ratio, and 95% queue length. The calculation results showed that all approach movements for each of the potentially impacted intersections currently operate at or above a LOS “C”, with the exception of the Durston Road and Ferguson Avenue intersection. All of the approaches at that intersection operate at LOS “D” except for the northbound approach which operates at LOS “E”. The northbound approach has a volume to capacity ratio (v/c) of 0.85 and the maximum queue is approximately 6 vehicles. All of the other approaches have a v/c of about 0.75 and queues of approximately 4 vehicles. Observations at this intersection confirm that the calculated level of service and queue conditions exist in reality. Traffic signal warrants for existing operations at the Durston Road and Ferguson Avenue intersection were completed (see Appendix F). It was determined that with existing volumes and lane geometry, two of the nine MUTCD traffic signal warrants would be met. Warrant #1 “Minimum Traffic Volumes” would be met at 164% of the minimum values. Warrant # 2 “Four Hour Volumes” would be met at 358% of the minimum values. The intersection of Baxter Lane and Davis Lane was recently converted from two-way stop control to all-way stop control due to recommendations in a previous study. Observations at that intersection with the new control confirmed that measurable improvements in vehicle queue lengths on Davis Lane have been realized.

Within the table, trip generation rates and resulting trip projections for the average weekday, am, and pm peak hour are illustrated. Trip generation calculations for the development were based upon the specific land use information provided by the developer. Trip generation rates were taken from ITE’s Trip Generation Report, 9th Edition. Data for ITE land use codes 210 (Single Family Detached Housing) and Code 220 “Apartments”, which were used to predict generation trip totals for the proposed development. Trip generation calculations indicate that there would be 3,545 average weekday trips (AWT), with 269 and 348 occurring during the peak am and pm hours respectively. Table 2.

When evaluating vehicular impacts, these non-vehicular and transit-related types of trips can often be considered negligible in terms of their potential impacts on site access points. Since the Flanders Mill Subdivision encompasses a large land area and Bozeman has a large population of bicycle and walking enthusiasts, bicycle and pedestrian trip modes could be considered as a portion of total trip generation. The number of alternate mode trips would be approximately 2% for the purposes of this analysis. Trip generation potential can be further refined by determining the number of “new” external trips that would appear, as vehicular traffic, at development access points. It is common that, for developments which contain multiple land uses and/or complementary Flanders Mill Subdivision TIS Page 12 facilities, a portion of trips that would have origins or destinations at such facilities are captured internally. These trips are part of the total trip generation number, but do not have origins or destinations external to the development site, and as such, do not have an impact of the traffic network external to the development. These types of trips are known as “Internal Capture Trips” (ICT). The ITE Trip Generation Handbook contains information regarding procedures for estimating ICT. In the case of Flanders Mill Subdivision, none of the trips were assumed to be ICT trips. Trips can be further categorized as primary purpose, diverted link, or passerby purpose trips. Primary purpose trips are trips for which the development is a primary destination from any particular origin. Diverted link trips are trips made to a development as a secondary destination that must be diverted from a path between the origin and primary destination. Passerby trips are also trips made to a development as a secondary destination, but without a diversion from the primary trip path (i.e., a stop on the way home from work). Passerby trips do not represent “new” trips added to the adjacent street system. Thus, site generated passerby trips must be considered as new external trips (movements) at the site approach or approaches, but do not appear as new trips on the adjacent street system. The ITE Trip Generation Report provides methods for estimating passerby trips for a variety of facilities. In the case of Flanders Mill Subdivision, there are no land uses normally associated with passerby trip attraction. Table 3 presents a summary of net trip generation that could be associated with street system impacts. The net number of external trip would be 3,474 AWT with 264 in the am hour and 341 in the pm hour. Table 3. Trip Mode & Classification Summary Total Ped/Bike Net Veh. ICT Net Ext.

For developments within a large urbanized area, the task is best accomplished through the creation of a computerized transportation model of the urban street system, which includes the proposed development changes. When the creation of a model is not feasible, realistic estimates can be made by determining the distribution of existing traffic volumes on the surrounding street system. The existing distribution can then be applied to newly generated trips, with adjustments made based upon the likely trip origins and destinations associated with the particular development land use or uses. For Flanders Mill, an existing conditions distribution was developed based upon area traffic patterns and an area of influence method, which considers the least travel time routing to external trip producers/attractors beyond the boundaries of the development. In addition to existing conditions, the trip distribution analysis considered the effect that future arterial street extension could have on directional distribution to and from the development. Results of the distribution analysis are summarized in Figure 4, on the following page. Overall, approximately 21% of the trips would be to and from the north; 54% would be to and from the east; 20% would be to and from the south; and the remaining 5% would be to and from the west. The percentages shown in Figure 4 would branch out onto other streets at distances farther from the site and the percentage of total trips on the Figure 4 streets would be diluted substantially at intersections located more than a mile from the subdivision. The percentage trip distributions shown in Figure 4 were used to calculate site traffic assignments on the surrounding street system. Flanders Mill Subdivision TIS Page 14 Flanders Mill Subdivision TIS Page 15 TRAFFIC REDISTRIBUTION Prior to developing site traffic assignments on the existing street system, it was necessary to redistribute existing traffic onto the new arterial street extensions (Oak Street and Ferguson Avenue). Redistributed traffic was calculated by determining existing directional traffic flows that enter and exit the area bounded by Baxter Lane, Davis Lane, Oak Street, Ferguson Avenue, Durston Road, and Flanders Mill Road. Existing traffic flows to and from external origins and destinations in all directions were routed through the study area and traffic volumes for each route were calculated. Travel time comparisons were made for existing routes and the new routes created by the Oak Street and Ferguson Avenue extensions. Whenever travel times were lower for routes using the new street extensions, traffic volumes associated that route were reassigned to the new route. Traffic volumes were essentially subtracted from one street and added to another all along each route. All of the reassigned traffic for each route was totaled and the resultant reassignments were applied to existing traffic flows. Figure 5, on the following page, illustrates the peak pm hour traffic movements at each of the existing system intersections and the average daily traffic (ADT) volumes that would result from the extension of both Oak Street and Ferguson Avenue. It can be seen that there would be substantial changes on Oak Street, Ferguson Avenue, Durston Road and, and Flanders Mill Road. ADT volumes of the new Oaks Street extension would be approximately 2,300 and on the new Ferguson Avenue extension, the ADT would be approximately 1,800. When comparing the volume of traffic entering the intersection of Ferguson and Avenue and Durston Road in Figure 5 with existing traffic in Figure 3, it can be seen that construction of the arterial roadway segments would reduce traffic by approximately 216 vehicles or 17% of the 1269 vehicles that currently enter the intersection in the peak pm hour . Flanders Mill Subdivision TIS Page 16 Flanders Mill Subdivision TIS Page 17 SITE TRAFFIC ASSIGNMENT The assignment of site traffic to a development’s street system and site access points is dependent upon several factors. Two such factors are external directional distribution and localized operational site conditions (i.e., the subdivision layout of streets). The combined calculation of demand and least time accessibility are then used to estimate likely movement volumes at each individual access point. Turning movements at each access point were then calculated through the application of the distribution to full development vehicular trip generation totals. For the Flanders Mill Subdivision, the aforementioned access points consist of 15 new street accesses to Baxter Lane, Flanders Mill Road, and Oak Street. These accesses would serve to distribute newly generated trips from Flanders Mill Subdivision to and from external origins and destinations. The directional distributions illustrated in Figure 4 in combination with 13 internal subdivisions access zones served by the 15 site approaches. Trip tables from each zone to each of the external trip distribution routes were created to determine the directional traffic flow at each of the access points. Both average daily and peak pm hour traffic volumes represented by trips in the trip table were the routed onto the street system. Results of the traffic assignment analysis are illustrated in Figure 6, on the following page. The volumes shown in Figure 6 are site generated traffic volumes only. Thus, the turning movements with zero traffic volumes are intersection movements that would not be impacted by development of this subdivision. Figure 7 presents site generated traffic at the subdivision access points. Two of the access points on Ferguson were combined because of their proximity to other accesses and identical distribution characteristics, which resulted in a total of 13 access points. The highest traffic volume access would be the northern-most access on Ferguson Lane. Flanders Mill Subdivision TIS Page 18 Flanders Mill Subdivision TIS Page 19 Flanders Mill Subdivision TIS Page 20 IMPACTS Traffic Volumes Traffic volume impacts for site developments can be quantified by determining the change in traffic volumes expected at various points within the surrounding network of streets. Site traffic assignments give an indication of what volume of traffic could potentially be added to the street system during the average day (ADT). Yet in almost all cases, it is very difficult to determine ADT on any section of street to within 10% accuracy. Thus, impact analyses on streets with relative percentage increases less than 10% are not normally considered critical. In any case, the percent change in daily traffic can only be used to identify general locations where impacts could be significant. It is the determination of volume changes during peak traffic flow periods that provides specific information on the type and location of impacts that could potentially occur. Figure 8, on the following page, illustrates the relative traffic volume impacts related to development site traffic and the redistribution of existing traffic to the surrounding street system. Figure 9 illustrates existing/redistributed traffic plus site traffic at each of the site access intersections. These figures also show the relative intersection volumes that would result if Flanders Mill Subdivision existed today (2013 traffic volume base). The traffic volumes incorporate the redistributed existing volumes plus the site generated traffic volume assignments. The percentage of ADT attributable to the development along key area streets is calculated using redistributed traffic volumes. Thus, there are definitive percentage increases shown for street sections on Oak Street and Ferguson Avenue that do not currently exist. Substantial volume increases over existing traffic would be realized on Baxter Lane, Harper Puckett Road, Davis Lane, Flanders Mill Road, and Oak Street. The percent increase attributable to subdivision development on other streets would be very minor. Exceptions to increased traffic would be the segment of Davis Lane, south of Baxter Lane, which would likely realize a slight decrease in ADT as a result of the redistribution of traffic created by the extension of Oak Street to Flanders Mill Road and the intersection of Ferguson & Durston, which would have a 10% reduction in total entering traffic. Flanders Mill Subdivision TIS Page 21 Flanders Mill Subdivision TIS Page 22 Flanders Mill Subdivision TIS Page 23 Capacity Table 4, on the following page, presents capacity analysis results for existing/redistributed plus site generated traffic at potentially impacted intersections. The addition of site development traffic and redistribution of existing traffic to the new arterial street extensions to existing (2013 baseline) traffic would only impact two of the eleven existing intersections. The intersection of Baxter Lane and Davis Lane would have reduced LOS on three of the four approaches. The LOS would be reduced from “B” to “C”. However, the v/c ratio would still be in the 0.65 range and there would be ample reserve capacity for substantial future growth. The other impacted intersection would be Durston Road and Ferguson Avenue. In this case, the impacts appear to be positive instead of negative. Redistribution of traffic due to the arterial extension would alleviate traffic demands on the north, east, and west approaches to the extent where the southbound, eastbound, and westbound approaches would go from existing LOS “D” to LOS “C” and the northbound approach would go from existing LOS “E” to LOS “D”. Capacity calculations (see Appendix C) for the new intersection of Oak Street and Ferguson Avenue, based on added site and distribution traffic, indicate that the northbound and southbound approaches would operate at LOS “E” if only single approach lanes were to be constructed at that intersection. The other new extension intersection of Flanders Mill Road and Oak Street would have all approaches operating at LOS “B”, using single lane approaches. Some level of mitigation would appear to be required at the intersection of Durston Road and Ferguson Avenue to enable operations acceptable to City of Bozeman standards. However, it should be understood that the calculations in Table 4 are for 2013 volumes plus full development of the site, which is a theoretical condition that would not exist in reality. The actual conditions that will likely occur would be construction of the arterial street connections eliminating existing capacity problems at that intersection. Additional capacity calculations indicate that all approach would operate at LOS “C” using traffic volumes shown in Figure 5. Also, improvements other than single approach lanes at the intersection of Oak Street and Ferguson Avenue would be required.

Year 2023 PM Hour Capacity Calculations at Key Site Accesses Intersection MOE Intersection Approaches ACCESS 1 at Riatta & Baxter Lane Traffic volumes used in Table 5 access capacity calculations were for future (year 2023) conditions. The through volumes on each street (see Figure 9) were increased by 30% which represents an annual growth rate in excess of 2%. Figure 10 illustrates the year 2023 traffic volumes at each of the subdivision access intersections. Flanders Mill Subdivision TIS Page 26 Flanders Mill Subdivision TIS Page 27 IMPACT MITIGATION As it is currently proposed, Flanders Mill Subdivision development is rather unique in the fact that the subdivision would complete key segments of the arterial street system in this portion of Bozeman and the Oak Street extension would actually bisect the subdivision. When the combined effect of redistributing existing traffic onto the new arterial extensions and adding site generated traffic is taken into account, there would be both negative and positive impacts. Most of the surrounding street system would not be negatively impacted in terms of efficient traffic operations. Impacts at the intersection of Durston Road and Ferguson Avenue would be positive, the reduction in traffic volumes created by the development’s construction of arterial street extensions would to increase the LOS to “C” or better on all approaches of the intersection. Traffic added to the intersection by construction of residences within the Flanders Mill Subdivision would occur over a long term period in concert with continued development of this portion of Bozeman. Thus, indirect impact mitigation at this intersection would be accomplished by construction of the key arterials streets by the developer. The proposed intersection of Oak Street and Ferguson Avenue would operate with the northbound and southbound approaches at LOS “E”, if single lane approach were to be constructed. Capacity calculations were completed to determine if additional lanes on all approaches would improve the anticipated LOS at this intersection. An intersection using 4 through lanes on Oak Street with auxiliary left-turn lanes and single thru lanes on Ferguson Avenue with auxiliary left-turn lanes was tested with stop control on Ferguson (see Appendix F). It was determined that the southbound approach would operate at LOS “D”. Another alternative would be all-way stop and two different concepts were tested: all-way stop with single approach lanes and all-way stop with single through lanes and auxiliary left-turn lanes on all approaches. Both of these concepts resulted in improved LOS. The single approach lane concept resulted in all approach operating at LOS “C” or better and the auxiliary left-turn lane concept resulted in all approaches operating at LOS “B”. Thus, it appears that all-way stop control Flanders Mill Subdivision TIS Page 28 would be required at the intersection of Oak Street and Ferguson Avenue. The number of approach lanes would be dependent upon the City of Bozeman’s arterial construction plan standards for both of these arterial streets. Traffic Signal Warrants Traffic signal warrant analysis was completed for both the Durston Road and Oak Street intersections with Ferguson Avenue (see Appendix F). It was determined that signal Warrant #1 “Minimum Vehicular Volumes” and Warrant #2 “Four Hour Volumes” would be met at both of these intersections. All signal warrant investigations also require an evaluation of alternative intersection controls to ensure that signals are justified in addition to being warranted. In this case both intersections can achieve acceptable levels of service using all-way stop control. In addition to all-way stop controls, roundabout intersections were evaluated and capacity calculations were completed (see Appendix E). Roundabout capacity analysis indicated that both the Oak Street and the Durston Road roundabouts would operate with all approaches at LOS “A” or better. The Oak Street roundabout could be designed for future expansion to accommodate dual circulation lanes, while right-of-way constrictions would make it difficult to expand operations at a Durston Road roundabout in the future. RECOMMENDATIONS Development of Flanders Mill Subdivision would add approximately 3,474 vehicle trips to the surrounding street system on the average weekday. While the level of daily trips can be considered substantial in comparison to existing ADT volumes on the surrounding streets, the impacts will be tempered somewhat by providing new arterial street segments that are needed to serve growing traffic demands in the area. This TIS has identified two existing intersections that would be impacted: Baxter Lane and Davis Lane, which would experience reduced levels of service, and the Durston Road and Ferguson Lane intersection would experience improved levels of services and provide much improved operations for a number years before LOS drops below acceptable Flanders Mill Subdivision TIS Page 29 values in the future. In addition to existing intersection impacts, construction of the Oak Street and Ferguson Road intersection as a part of subdivision development would require enhanced traffic control to achieve acceptable levels of service. All of the proposed subdivision street accesses would operate at acceptable levels of service when the subdivision is fully occupied and year 2023 traffic projections are present on the adjacent streets. Stop control at all of the subdivision access intersections on the surrounding street system would be required. Traffic volumes at those intersections are not significant enough to justify auxiliary turn lanes either on the through streets or on the minor street approaches. The following are recommendations related to traffic operations at the Oak Street and Durston Road intersections with Ferguson Avenue. 1. The typical sections on both the Ferguson Avenue and Oak Street extensions should conform to City of Bozeman standards established for both of these streets as may be detailed in the current transportation plan or required by City policy and practices. Ferguson Road, south of Durston Road provides two through lanes and bike lanes on both sides of the street. Oak Street, east of Davis Lane provides two through lanes in each direction and a wide median section and left-turn lanes at intersections. Anticipated traffic volumes on Oak Street between Ferguson Avenue and Flanders Mill Road within the next 10 to 20 years would not justify such a wide typical section and if not mandated by City of Bozeman standards, the Oak Street typical section could be reduced to two through lanes at a minimum. 2. The intersection of Oak Street and Ferguson Avenue could be constructed with single approach lanes and acceptable levels of service could be achieved using all- way stop control. Eventually this intersection would need to be signalized, however construction of a roundabout would have superior operational characteristics in terms of safety and efficiency and design of this intersection should incorporate a single lane roundabout with provisions for future conversion to a dual lane roundabout. Flanders Mill Subdivision TIS Page 30 3. Two concept improvements could be considered for the intersection of Durston Road and Ferguson Lane in the future. Installation of a traffic signal would improve operations to LOS “B”. Reconstruction of the intersection as a single lane roundabout would improve operations to LOS “A”. The roundabout would provide the best operating environment, but there would be no room for future expansion. A traffic signal would provide substantial operational improvements for vehicular and pedestrian traffic. With the v/c ratio being less than 0.5 its expected life would be in excess of 10 to 15 years before additional lanes would be required. Because of the relative benefits for the costs involved, the traffic signal improvements would appear to be the most favorable improvement of the three. Since this improvement would not be required for a number of years after the subdivision is developed, the City of Bozeman should consider assessing a proportionate share of construction costs to all developments contributing to traffic at that intersection. It should also be kept in mid that even with full development of the Flanders Mill Subdivision the net change in entering traffic volumes at that intersection is a negative 10% of exiting volumes or approximately 129 fewer vehicles in the peak pm hour.
