Madison Engineering 895 Technology Blvd, Suite 203 Bozeman, MT 59718 December 11, 2017 Re: Gran Cielo Subdivision Traffic Impact Study Addendum Subsequent to submittal of a Traffic Impact Study (TIS) dated October 24, 2017 for the proposed Gran Cielo Subdivision, the City of Bozeman Planning staff reviewed the study and requested additional information in a memo dated November 18, 2017. Item number 9 in that letter indicated that there are several development projects within the vicinity of the subdivision that were not included in future traffic projections that need to be included in the analysis. The three developments mentioned in the letter are all contained within the boundaries of the Meadow Creek Subdivision. Since there were no TIS reports prepared for the individual projects listed, it was determined that the entirety of Meadow Creek Subdivision should be included in the analysis A TIS for Meadow Creek Subdivision was completed by Robert Peccia and Associates in 2005. That study indicated that the subdivision would generate 5,382 trips on the average weekday with 414 in the peak am hour and 530 in the peak pm hour. Trip distribution and traffic assignment analysis completed with that study no longer apply to 2017 conditions because of new street links that have been created and additional development in the southern areas of Bozeman. Therefore, trip distribution percentages determined for the Gran Cielo subdivision were used to assign Meadow Creek Subdivision traffic. Attached Figure 7 was created to illustrate the additional traffic that would be attributed to Meadow Creek Subdivision on the area street system. Since a portion of Meadow Creek Subdivision has already been developed, it was necessary to subtract existing traffic from the overall trip generation totals, as noted in Figure 7. The resultant trip generation from future development of Meadow Creek Subdivision would be 3,682 average weekday trips (AWT) with 284 in the AM hour and 362 in the peak PM hour. The Meadow Creek Subdivision traffic assignment volumes shown in Figure 7 were added to traffic shown in Figure 6 of the original TIS for Gran Cielo Subdivision. Figure 6 Revised is attached and represents an estimate of year 2032 traffic volumes with full occupation of the Gran Cielo Subdivision. MARVIN & ASSOCIATES 1300 N.

Box 80785 Billings, MT 59108-0785 Phone: 406-655-4550 FAX: 406-655-4991 Page 2 Capacity calculations (Revised Appendix C-3 attached) were completed for future conditions based upon the peak am and peak pm volumes, as shown in Figure 6 Revised. Table 4 Revised, below, is a summary of the capacity calculations results. In comparing Table 4 Revised to the original Table 4, it can be seen that some of the levels of service (LOS) for individual movements have changed at the two intersections on S 19th Avenue. The most appreciable difference would be at the Stucky Road and S 19th Avenue intersection during the peak pm hour, where the overall intersection LOS would drop from LOS “C” to LOS “D”.

Box 80785 Billings, MT 59108-0785 Phone: 406-655-4550 FAX: 406-655-4991 Page 3 From this supplemental TIS analysis it appears that the addition of the Gran Cielo Subdivision, as proposed, would not substantially impact the surrounding streets or intersection operations, if it existed at the present time. However, future operations at the intersection of Stucky Road and S 19th Avenue would experience increased delays during the peak pm hour periods, if Gran Cielo is fully developed at the same time as all other area developments are in-place. It should be noted that future area street improvements have the potential to mitigate these impacts if implemented within the next 15 years. An extension of S 27th Avenue from Stucky Road to Garfield street would draw appreciable traffic demand from S 19th Avenue, which could allow acceptable operation at the Stucky Road and S 19th Avenue intersection in the year 2032. In the event that that the S 27th Avenue connection is not completed in that time period, dual left turn lanes for eastbound traffic on Stucky Road and an exclusive southbound right-turn lane on S 19th Avenue could be considered when future improvements to Stucky Road is designed.

Marvin & Associates was retained by Madison Engineering 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 the Gran Cielo Subdivision development and to provide recommendations regarding the mitigation of any identified impacts. Having reviewed the proposed land use development plan, Marvin & Associates completed an 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 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 Gran Cielo Subdivision development property is bounded on its southern border by Graf Street and agricultural land on the remaining boundaries. (See Figure 1). The property consists of 39.8 acres in R-3 zoning and 8.95 acres zoned R-4. No specific plans have been developed within the overall subdivision layout, but it is estimated that approximately 743 residents would occupy the multi-family lots at full development. This TIS was prepared to evaluate the newly proposed development’s impacts on the roadway system as it currently exists and in the future. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 2 Access to the Gran Cielo Subdivision property would initially be provided from an extension of Graf Street to the west and from an extension of S 27th Avenue to the north. Two new street accesses would connect to Graf Street and four accesses would connect with S 27th Street. The City of Bozeman’s transportation plan indicates that at some future date, S. 2th would be extended from Graf Street to Garfield Street, south of the site. No specific plans were set forth for a future extension of Graf Street to the west. The transportation plan also indicates that Stucky Road will be reconstructed to provide three traffic lanes west of S 19th Avenue in the future. Potential traffic impacts associated with the initial development of Gran Cielo Subdivision property would be confined to intersections of Graf Street and Stucky Road on South 19th Avenue. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 3 EXISTING CONDITIONS Streets & Intersections Adjacent and potentially impacted public streets within a one half mile distance of the development include South 19th Avenue and the intersections of Graf Street and Stucky Road with South 19th Avenue. 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 this intersection. North of Graf Street, South 19th Avenue transitions to a two lane road section and then transitions back to a wider section at the intersection with Stucky Road, approximately 0.5 miles south 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 is no curb and gutter on 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. 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 Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 4 approximately 40’ wide at its intersection with South 19th Avenue and tapers back to a width of approximately 28’ west of the intersection. Traffic Volumes Hourly electronic traffic counts were taken in August 2017 on Stucky Road and two additional counts were taken on S 19th Avenue and on Graf Street in 2015. Additional counts were also taken on S 19th Avenue in 2016. The counts provided hourly variations, which were used to determine peak hour conditions and provide base volumes for average weekday projections on intersecting roadways. Summaries of the counts can be found be Appendix A of this report. The weekday peak hour traffic volumes were found to occur between 4:30 and 5:30 pm and between 7:30 and 8:30 am. Peak AM & PM turning movement counts were taken at both the Graf Street and Stucky Road intersections with South 19th Avenue in September of 2017. Average weekday traffic (AWT) volumes were calculated on street links using proportional turning movement volumes in relation to the AWT volume electronic counts. Figure 2 presents existing am & pm peak hour turning movement volumes at the potentially impacted intersections. Street segment average weekday traffic volumes are also depicted in this figure. The existing Intersection of S 27th Avenue and Graf Street was also counted, but that intersection only involves westbound left turn movements and northbound right turn movements and serves very few vehicles. No pedestrian activity was noted during the counting periods, but bike traffic was relatively substantial at the intersection of Stucky Road and South 19th Avenue. There were 12 bikes turning left onto South 19th Avenue and 6 bikes turning right onto Stucky Road from South 19th Avenue during the peak pm hour period. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 5 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. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 6 Capacity Peak am and pm hour existing condition capacity calculations were completed for the potentially impacted intersections using the HCS 2010 and SigCInema software packages (see Appendix C). Table 1 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 approaches at each of the potentially impacted intersections currently operate at or above a LOS “C”. Since there is no intersection control at the intersection of S 27th Avenue and Graf Street, it was not possible to calculate capacity. Thus, the free flow conditions would result in LOS “A”.

Within this 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. The R-3 zone would accommodate 6.5 units per acre and the R-4 zone would have 10.4 units per acre. Using a density of 2.0 units per unit resulted in approximately 784 apartment residents. Trip generation rates were taken from ITE’s Trip Generation Report, 9th Edition. Table 2 indicates that initial development of Gran Cielo Subdivision property would generate approximately 2,656 average weekday trips (AWT) with 215 trips in the am hour and 292 trips during the peak pm hour. Land use developments typically produce multi-modal trips that include pedestrian, bicycle, and transit trips, in addition to other vehicular trips. 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.

Gran Cielo Subdivision Trip Generation * ITE Trip Generation Report, 9th Edition Code 220 "Apartments" Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 8 area bicycle and pedestrian trip modes would probably not initially account for an appreciable number of trips. As future development in the surrounding area becomes denser, use of alternative modes will increase. However, it was assumed that none of the trips would be associated with pedestrian and bike modes. 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 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). In the case of Gran Cielo Subdivision Development, there are no diverse land uses that could create ICTs in the future. Therefore, no internal capture trips were applied to external trip numbers. 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 proposed development would not be conducive to attraction of passerby traffic and it was assumed that none of the trips could be classified as passerby trips. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 9 TRIP DISTRIBUTION There are various methods available for determining the directional distribution of trips to and from site developments. 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 this development, an existing condition distribution was developed based upon area traffic patterns. Results of the distribution analysis indicated that 81% of the trips would be distributed to and from the north, 12% would be directed to and from the south, 7% would be to and from the east, and the remaining 5% would be to and from the west. SITE TRAFFIC ASSIGNMENT The assignment of site traffic to the surrounding 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. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 1 0 For the Gran Cielo Subdivision Development, the aforementioned access points consist of accesses on S 27th Avenue and Graf Street and all of the trips would be funneled thru the Graf Street and S 19th Avenue intersection. With a future extension of S 27th Avenue to Stucky Road, traffic assignments would be substantially different (see “Future Operations” section of this report). Average weekday and peak hour site generated traffic was routed onto the street system. Resulting traffic volume assignments are illustrated in Figure 3 with volumes that are associated with full development of the study subdivision. The highest site traffic volumes would occur on Graf Street. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 1 1 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 weekday (AWT). Yet in almost all cases, it is very difficult to determine AWT 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 4 illustrates the relative traffic volume impacts related to development site traffic. Figure 4 also illustrates year 2017 background traffic volume plus initial site traffic at each of the potentially impacted intersections. Traffic volumes would increase on all of the potentially impacted streets, yet none of the streets east and south of the Graf Street and S 19th Avenue intersection would exceed the level of significance associated with a 10% increase. The highest percent increase attributable to initial development would be approximately 900% on a short section of Graf Street immediately east of South 27th Avenue. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 1 2 Capacity Table 3 presents capacity analysis results for year 2017 background traffic plus site generated traffic at the potentially impacted intersections. The addition of site development traffic to background traffic would not in itself substantially impact any of the existing intersections. In comparing Table 3 with Table 1, it can be seen that some of the movements at Stucky Road and S 19th Avenue would have a decreased LOS from “B” to “C” but the LOS on all legs of the intersection would remain the same as exists. The addition of two legs to the Graf Street and S 27th Avenue intersection would result in LOS “A” on all legs except for LOS “B” on the Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 1 3 southbound approach. The calculations assumed that stop control would be on S 27th Avenue, since Graf Street would have the highest volume of traffic. Future Operations Future traffic volumes were calculated using an annual growth rate of 2% per year and applied to the year 2017 through traffic volumes on S 19th Avenue. Through traffic on Graf Street west of S 19th would be dependent upon future development west of S 27th Street, which is speculative at this time.

Traffic Growth on Graf Street east of S 19th Avenue includes a number of known developments: University Districts Apartments Phases 2 and 3, University District Lot 5 commercial/residential subdivision, and the Yellowstone Theological Institute on the north side of Graf Street. Traffic projections for those developments along with traffic reassignment calculations for the Graf Street and 11th Avenue extension projects were used to develop year 2032 traffic volumes. All of the above noted assumptions were used to determine potential traffic volumes on the impacted street system. Figure 5 presents the full subdivision development traffic assignment for the Gran Cielo Subdivision development. Gran Cielo Subdivision Traffic Impact Study MARVIN & ASSOCIATES 10/24/2017 1 5 Figure 6 presents the combined background traffic and full development traffic volumes at the potentially impacted intersections. It can be seen that Traffic on Graf Street, immediately east of S 27th Avenue, would actually be less than the volumes shown in Figure 4. This is due to the fact that approximately 67% of the site traffic would use S 27th Avenue to access Stucky Road which would have a travel time advantage for trips to and from the north. An extension of S 27th Avenue north of Stucky Road was not considered, since timing of those improvements would probably be dependent upon future development scenarios between Stucky Road and Garfield Street. .

Capacity calculations for the Stucky Road and South 19th Avenue intersection were based on future lane geometry and traffic signal modifications that would be developed as a condition of extending Stucky Road east of S 19th Avenue.

It can be seen that some of the movements at the Stucky Road and S 19th Avenue intersection would operate at LOS “D” in the future, but all of the approach legs would operate at LOS “C”. CONCLUSIONS & RECOMMENDATIONS Development of Gran Cielo Subdivision Development property, as detailed in this report, would add 2,656 vehicle trips to the surrounding street system on the average weekday when the subdivision is fully developed. The TIS has determined that this development will have minimal impacts to traffic operations on South 19th Avenue and at the intersections of Stucky Road and South 19th Avenue if it existed today. Analysis of future traffic growth on the surrounding street system along with planned system improvements indicate that the Stucky Road and S 19th Avenue intersection would have some movements operating below the ideal LOS. However, the impacts would not be sufficient to cause any of the intersection approaches to suffer a LOS less than “C” When design of improvements to Stucky Road are begun, dual left turn lanes on the eastbound approach to the South 19th Avenue intersection should be considered. Time saved by using dual left turns would allow all movements within the intersection to operate at LOS “C” or better. The intersection of S 27th Avenue and Graff street should be controlled using stop signs on the on the S 27th Avenue northbound and southbound intersection approaches. Stop control should also be used on each of the internal street accesses to both Graf Street and S 27th Avenue.
