A complete preliminary plat application was submitted on December 20, 2013 and deemed acceptable for initial review on December 30, 2013. The preliminary plat was reviewed by the DRC on January 8, 15, and 22, 2014. On January 22, 2014 the DRC Staff determined the submittal contained detailed, supporting information that is sufficient to allow for the review of the proposed subdivision. The DRC provided favorable recommendation was forwarded, for consideration, to the City Commission. 101 P13048 Staff Report for the South University District Phase 1 Minor Subdivision Page 8 of 22 Public notice was sent to property owners of record within 200 feet of the subject property via first class mail, on January 9, 2014. One comment letter was received by the Community Development Department on January 7, 2014. The comment letter is attached to this report in Appendix F. On January 24, 2014 this minor subdivision staff report with a recommendation of conditional approval was forwarded to the City Commission. The City Commission is scheduled to make a final decision at their February 3, 2014 public meeting. The final decision for a First Minor Subdivision from a Tract of Record Preliminary Plat must be made within 35 working days of the date it was deemed adequate for review or in this case by March 12, 2014. 4) Compliance with Chapter 38, BMC and other relevant regulations Based on review of the DRC, and the Department of Community Development all applicable regulations appear to be met.

Primary subdivision review criteria are not required for first minors from a tract of record therefore, are not included in this report. Preliminary Plat Supplements A subdivision pre-application plan review was completed by the Development Review Committee on December 11, 2013. With the pre-application plan review application, waivers were requested by the applicant from Section 38.41.060 “Additional Subdivision Preliminary Plat Supplements” for several of the standard preliminary plat supplements due to the nature of this property. The DRC granted the requested waivers. Staff offers the following summary comments on the supplemental information required with Article 38.41, BMC. 102 P13048 Staff Report for the South University District Phase 1 Minor Subdivision Page 9 of 22 38.41.060.A.1 Surface Water Surface waters on the property consist of Mandeville Creek that flows north to south through the center of the property. There are two irrigation ditches on the property, one flowing along South 19th Avenue and one flowing along South 11th Avenue to the Montana State University irrigation reservoir. Connected and unconnected wetlands are present on the property. A Wetlands Delineation report was conducted by Stahly Engineering in May, 2011. Wetlands are located along Mandeville Creek throughout the property. All wetland areas are encompassed within the parkland easement, there are no wetlands within the proposed development area. 38.41.060.A.2 Floodplains Mandeville Creek does not include a mapped 100 year floodplain. The watercourse has a drainage basin of approximately one square mile. Due to the small drainage area and its location within a large master planned park, this creek does not pose a flood hazard to development within the subdivision. 38.41.060.A.3 Groundwater Nine monitoring wells were excavated on the property and monitored during the summer of 2011. Data gleaned from the test wells indicate ground water depths vary from approximately thirteen feet deep to less than one foot in wetland areas. In general, development in Phase 1 is proposed in areas with groundwater depths ranging from six to thirteen feet. Installation of municipal water and sanitary sewer services will reduce any concerns regarding the potential of groundwater degradation from private systems. 38.41.060.A.4 Geology, Soils and Slopes The geotechnical report did not identify any unusual geologic hazards on the property. No significant physical features or topographical conditions have been identified, and no slopes in excess of fifteen percent (15%) grade are evident. Due to gentle slopes on the property large cuts and fills are not anticipated. 38.41.060.A.5 Vegetation No mature vegetation or critical vegetation species are found on the site. The site currently consists of native grasses and pasture. To control the spread of noxious weeds a Memorandum of Understanding with the County Weed District will be required to be submitted with the final plat. The application has a previous noxious weed management plan for the site that was approved by the County Weed Board in February, 2012 and is valid for three years. 38.41.060.A.6 Wildlife The applicant states there are no known endangered species or critical game ranges on site. The past agricultural uses and proximity to the City make the property less desirable to wildlife. Montana Department of Fish Wildlife and Parks was notified of the preliminary plat and did not 103 P13048 Staff Report for the South University District Phase 1 Minor Subdivision Page 10 of 22 provide comment on the proposal. The 50-foot watercourse setback along the Mandeville Creek watercourse and wetlands will protect any riparian environment already established on the property. 38.41.060.A.7 Historical Features A cultural resource study was conducted in April, 2012 by Anthro Research, Inc. and found that no significant cultural, historic or archaeological features exist on the property. 38.41.060.A.8 Agriculture Historically, the subject property has been used for agricultural purposes as part of a larger farmstead until such time that the state highways, streets, and another City and County development have limited the overall use of the property as a viable standalone farming unit. The South University District has been designated for development by the City’s growth policy, municipal zoning, and master planning. 38.41.060.A.9 Agricultural Water User Facilities There are two irrigation ditches on the property, one flowing along South 19th Avenue and one flowing along South 11th Avenue to the Montana State University irrigation reservoir. These ditches are under the jurisdiction of the Middle Creek Ditch Company. All irrigation ditches are located on Lot 3, a remainder lot subject to further subdivision review, and will remain unaltered. The owner’s of the South University District property own one share in the Middle Creek Ditch Company. Conditions of approval three through six are recommended to comply with State statute related to agricultural water user facilities and as requested by the Middle Creek Ditch Company. 38.41.060.A.10 Water and Sewer Water for domestic and fire protection and sanitary sewer service will be provided by connections to the City of Bozeman municipal system. The City Engineering and Water and Sewer Divisions have reviewed the plans and find there is adequate capacity to serve the subdivision. Final approval of the water distribution system and sewage collection/disposal system will be obtained through normal approval procedures of infrastructure and final plat review by the City Engineering Division, Superintendent of Water/Sewer, and Montana Department of Environmental Quality. 38.41.060.A.11 Stormwater Management A preliminary stormwater management plan was provided in the application. Storm water from Phase 1 streets and Lot 1 development will be collected in curbs and gutters and transported in storm sewers to two detention basins located in the Phase 1 public park. Outlet structures control the release rate from the detention basins to preconstruction runoff rates. 104 P13048 Staff Report for the South University District Phase 1 Minor Subdivision Page 11 of 22 38.41.060.A.12 Streets, Roads and Alleys The approved South University District Master Plan provides the planned transportation system for the district. The street network for Phase 1 of the South University District will include dedicated rights of way and public street easements for the perimeter streets surrounding lots 1 and 2. South 11th Avenue, a collector will be widened to its full section along the east side of the subdivision and Campus Boulevard will be constructed along a portion of the frontage of Lot 1. A shared use pathway will be constructed in the State Street right-of-way to the western edge of Lot 1. The City Engineering Division has approved the street layout and the accompanying level of improvements required. Underlying public street easements will be required to be reconveyed in order to accommodate the proposed street layout. A preliminary traffic analysis has been completed and submitted for the residential and commercial component proposed for Lot 1 of Phase 1. The analysis stated that the resulting traffic impacts to the existing city streets were found to be minimal. Planned for group living uses to support Montana State University (MSU), primary travel to and from Lot 1 is anticipated to be by bicycle and pedestrian traffic to and from the university. Traffic generation rates were obtained from counts at the MSU dormitories normalized for students with cars. The trip generation measured was 2.5 trips per day per resident with a car. This results in a total trip generation from this project and future commercial uses of approximately1,960 new Average Daily Trips on South 11th Avenue. Three intersections were analyzed along Kagy Boulevard for capacity impacts; Kagy and 19th, Kagy and 11th and Kagy and 7th. The largest impacts are on the 11th and Kagy intersection, but since this development is located on the under-utilized south leg of this intersection, impacts are negligible. The intersection of 7th and Kagy continues to operate below a LOS “C” and a formal request for an exception to this standard has been submitted and was previously approved by the City Engineer. Kagy Boulevard is proposed to be improved in 2015 in the City of Bozeman 2014-2018 Capital Improvements Plan, thus future traffic projections were only carried out to 2015 with the existing geometry. Future improvements to Kagy Boulevard will improve the overall level of service. Bicycle traffic is accommodated by bike lanes on the collector streets, South 11th Ave and Campus Boulevard. Shared-use pathways and trails are proposed for the balance of the perimeter street rights-of-ways and/or easements, until such time that construction of these streets are required. Traffic calming bulbs are proposed at street intersections to provide reduced speeds, shorter crosswalks, and better sighting of pedestrians entering the street. One allowable access to Lot 1 is via Arianna Way in the Stadium Center Business Park due north of this subdivision. Arianna Way is a private street with public access. Staff recommends condition nine to require monitoring of the future traffic accessing Lot 1 through Arianna Way to determine if the amount of traffic exceeds City thresholds for traffic calming mitigation. A wavier of right to protest a special improvement district is recommended as condition of approval eight in order to complete State Street right of way improvements at such time the overall master plan development of the South University District and future uses have been identified and traffic studies related to those uses have identified the need for State Street to lessen congestion at other intersections in the vicinity. 105 P13048 Staff Report for the South University District Phase 1 Minor Subdivision Page 12 of 22 38.41.060.A.13 Utilities Utility service providers have been contacted and plan to provide service to the subdivision. Service providers indicated they will be able to serve the additional demand. All utilities will be required to coordinate their installation and location with the installation of the infrastructure. Utility easements are required on the final plat. 38.41.060.A.14 Educational Facilities Supplemental information waived by the DRC. The proposed uses identified in the approved South University District Master Plan are not related to school age children. The impacts to Bozeman School District educational facilities are expected to be minimal to nonexistent from this subdivision. 38.41.060.A.15 Land Use Supplemental information waived by the DRC. The subdivision complies with the existing zoning designation of REMU, Residential Emphasis Mixed Use District and the approved South University District Master Plan. 38.41.060.A.16 Parks and Recreation Facilities Supplemental information waived by the DRC. A first minor subdivision is exempt from providing parkland pursuant to Section 38.27.020.B, BMC. 38.41.060.A.17 Neighborhood Center Plan Supplemental information waived by the DRC. A neighborhood center is not required for a minor subdivision. 38.41.060.A.18 Lighting Plan Subdivision lighting is proposed and is in conformance with adopted design standards. Final design of the lighting system is required with the infrastructure plan submittal and shall be in accordance with the City’s adopted Engineering Design Standards and Specifications. 38.41.060.A.19 Miscellaneous Supplemental information waived by the DRC. The subdivision will not impact access to any public lands and there are no identified hazards in proximity to the subject property. 38.41.060.A.20 Affordable Housing Supplemental information waived by the DRC. Workforce housing requirements do not apply to subdivisions creating less than 10 residential parcels. In addition, the Workforce Housing Ordinance (Ordinance 1710) had been suspended by the City Commission. APPENDIX A –ADVISORY CODE CITATIONS The following code provisions are identified for informational purposes as the project moves forward.

The intent and purpose of the residential emphasis mixed-use (REMU) district is to establish areas within Bozeman that are mixed-use in character and to provide options for a variety of housing, employment, retail and neighborhood service opportunities within a new or existing neighborhood, while providing predictability to landowners and residents in uses and standards. There is a rebuttable presumption that the uses set forth for the district will be compatible both within the district and to adjoining zoning districts when the standards of this chapter are met and any applicable conditions of approval have been satisfied. Additional requirements for development apply within overlay districts. 1.It is further the intent of this district to implement the principles of the adopted growth policy: Neighborhoods: a. Create self-sustaining neighborhoods that will lay the foundation for healthy lifestyles; b. Support compact, walkable developments that promote balanced transportation options; c. Have residential as the majority use with a range of densities; d. Provide for a diverse array of commercial and civic uses supporting residential; e. Have residential and commercial uses mixed vertically and/or horizontally; f. Locate adjacent to residential neighborhoods that can sustain commercial uses within walking distance and a wider range of housing types; g. Encourage developments that exhibit the physical design characteristics of vibrant, urban, and pedestrian-oriented complete streets; Sense of Place: h. Support or add to an existing neighborhood context; i. Enhance an existing neighborhood's sense of place and strive to make it more self-sustainable; j. Encourage a new neighborhood commercial center(s) with a unique identity and strong sense of place; k. Develop commercial and mixed-use areas that are safe, comfortable, and attractive to pedestrians; l. Reinforce the principle of streets as public places that encourage pedestrian and bicycle travel, transit, on-street parking and physical elements of complete streets; Natural Amenities: m. Preserve and integrate the natural amenities into the development; n. Appropriately balance a hierarchy of both parks and public spaces that are within the neighborhood; Centers: o. Group uses of property to create vibrant centers; p. Where appropriate create a center within an existing neighborhood; q. Facilitate proven, market driven projects to ensure both long and short-term financial viability; r. Allow an appropriate blend of complimentary mixed land uses including, but not limited to, retail, offices, commercial services, restaurants, bars, hotels, recreation and civic uses, and housing, to create economic and social vitality; s. Foster the master plan development into a mix of feasible, market driven uses; t. Emphasize the need to serve the adjacent, local neighborhood and also the greater Bozeman area as well; u. Maximize land use efficiency by encouraging shared use parking; Integration of Action: 110 P13048 Staff Report for the South University District Phase 1 Minor Subdivision Page 17 of 22 v. Support existing infrastructure that is within and adjacent to REMU zones; w. Add to existing transportation and open space network, encourage pedestrian and bicycle travel; x. Encourage master planned communities with thoughtful development; y. Provide flexibility in the placement and design of new developments and redevelopment to anticipate changes in the marketplace; z. Provide roadway and pedestrian connections to residential areas; aa. Facilitate development (land use mix, density and design) that supports public transit, where applicable; bb. Provide flexibility in phasing to help insure both long and short term financial viability of the project as a whole; Urban Density: cc. Encourage efficient land use by facilitating, high-density, single or multi-story housing, commercial and retail development; dd. Provide transitions between high-traffic streets and adjacent residential neighborhoods and Sustainability: ee. Promote sustainable communities through careful planning. 2. To accomplish the intent of the district, the REMU district may be located within existing and established neighborhoods, or located in new undeveloped areas of the city. Implementation of certain regulations herein may be implemented with regard to the specific characteristics and location of a development site. REMU districts should be located adjacent to or near planned or existing residential development to enhance walking and bicycle use. Adopted Growth Policy Designation: The subject property is planned Residential Emphasis Mixed-Use (REMU). The REMU land use designation category promotes neighborhoods with supporting services that are substantially dominated by housing. A diversity of residential housing types should be built on the majority of any area within this category. Housing choice for a variety of households is desired and can include attached and small detached single-household dwellings, apartments, and live-work units. Residences should be included on the upper floors of buildings with ground floor commercial uses. Variation in building massing, height, and other design characteristics should contribute to a complete and interesting streetscape and may be larger than in the Residential category. Secondary supporting uses, such as retail, offices, and civic uses, are permitted at the ground floor. All uses should complement existing and planned residential uses. Non-residential uses are expected to be pedestrian oriented and emphasize the human scale with modulation as needed in larger structures. Stand alone, large, non-residential uses are discouraged. Non-residential spaces should provide an interesting pedestrian experience with quality urban design for buildings, sites, and open spaces. This category is implemented at different scales. The details of implementing standards will vary with the scale. The category is appropriate near commercial centers and larger areas should have access on collector and arterial streets. Multi-household higher density urban development is expected. Any development within this category should have a well integrated transportation and open space network which encourages pedestrian activity and provides ready access within and to adjacent development. 111 P13048 Staff Report for the South University District Phase 1 Minor Subdivision Page 18 of 22 APPENDIX C – DETAILED PROJECT DESCRIPTION AND BACKGROUND Project Description The proposal includes the subdivision of one existing tract of land of approximately 127 acres into three lots. One lot will be available for initial development and lots 2 and 3 will be restricted to further subdivision review prior to development. This subdivision is a first minor subdivision from a tract of record and does not require Planning Board review or a public hearing. Water and sewer will connect to city services. All stormwater runoff will be managed on site in retention ponds. APPENDIX D – NOTICING AND PUBLIC COMMENT A subdivision pre-application was submitted on November 13, 2013. The pre-application was reviewed by the Development Review Committee (DRC) on November 27, December 4 and 11, 2013 and summary review comments were forwarded to the applicant in preparation of the preliminary plat application and granted numerous supplemental information waivers under 38.41.060, BMC.

The subdivision would create one 9.82-acre parcel on which a 139-unit, 499 bedroom group living (student housing) project with mixed use buildings would be constructed. In addition, two “R” lots would be created, Lots 2 and 3 shown on the plat. The larger “R” lot would be would be approximately 108-acres and the smaller one will have a net area of approximately 3.66-acres. Development of either “R” lot will require further review and installation of public infrastructure improvements. Restrictions will be placed on them until that occurs. In addition to the lots, the subdivision would produce a 9.38-acre public park (net area, secured temporarily by a public park easement), public street right-of-way dedications for portions of South 11th Avenue and Campus Boulevard and public street and access easements. In order to reduce the printed volume and redundancy in submittal of application materials, electronic files have been provided for some of the subdivision application components which have been provided previously. Hard copies of studies such as the Traffic Impact Study or Wetlands Delineation, have already been submitted with the SUD Master Plan and the Stadium View Apartments preliminary site plan and will not be re-submitted at this time. The components for which electronic files are being submitted are noted in the Table of Contents as “Electronic Appendices”. While a number of waivers to the supplemental information required by the environmental assessment (UDC Section 38.41.060) were requested with the subdivision pre-application plan, the majority of the informational requests have been answered anyway by this application. It was felt that in order to provide sufficient information for adequate findings of fact, it was simpler to provide the information. On a related note, a letter was sent on December 6, 2013 to the District 3 Fish, Wildlife and Parks Department requesting comment on this project. As of this writing, a response letter has not been received. Project Summary The SUD Phase 1 Subdivision is within the recently annexed and zoned South University District Master Plan area. A master development plan for the property was approved by the Bozeman City Commission and amended in November of 2013 (hard copies of the SUD Master Plan are on file with the Planning 121 2 Department and an electronic file is provided in the application Appendix). The subdivision site is currently vacant and a Preliminary Site plan for development of the student housing project has been submitted for review. The intention would be to begin construction of the subdivision and site infrastructure the spring of 2014 with occupancy slated for fall of 2015. As noted, the project would provide 139 living units with 499 bedrooms and provide two mixed use building fronting on South 11th Avenue. The architectural features of the mixed use buildings will be different from the residential structures. The lower floor of the northern mixed use building (building 1) will have a mix of commercial uses and administrative spaces. The initial function of the south mixed use building (building 2) will be entirely residential. To simplify repurposing and conversion of the first floor to commercial uses, it is being designed with 12-foot high ceilings on the first floor, interior structural features that will allow simplified conversion to storefronts and interior spaces and window and door treatments to resemble the north building. Parking for the project is enclosed in a central courtyard surrounded by a perimeter of project buildings. The central courtyard is separated into north and south halves by a large open space mall which will provide for on-site recreation opportunities. Pedestrian circulation is provided in all directions and is focused to maximize student movement northeast towards the MSU campus. The west end of the parking courtyard is left unencumbered with buildings so as to allow for potential extension of the parking/open space courtyard concept to serve a future development. Hard surface trails in the State Street, Campus Boulevard and South 14th Avenue public street easements will connect Phase 1 to the park. Primary access to the central courtyard and open space mall will be from South 11th Avenue on the east and from Campus Boulevard on the south. A third street connection to Stadium Drive on the north is proposed. SUD Master Plan Conformance Master Plan conformance can be measured in several ways. First, the Phase 1 Subdivision conforms to the “High Density Residential and Mixed Residential /Commercial” land use designations shown for the project site in the SUD Master Plan Map. As shown in the SUD Master Plan, the transportation circulation pattern for the high density residential areas allows for alternative solutions to the standard street and block pattern in the Bozeman UDC. This first phase subdivision is in conformance with the alternatives shown in the Master Plan. Right-of-way dedications and public access easements for the location of Campus Boulevard and South 14th Avenue would be established by this subdivision; in the same locations shown in the Master Plan. The park plan for the first phase is the same place and is essentially the same plan as shown in the SUD Master Plan. 122 3 Covenants for the Phase 1 subdivision are framed from those provided in the Master Plan and would establish the overall South University District Property Owners Association, as recommended in the Master Plan. Given that there will be only one developed portion of the SUD Master Plan area at this time, bylaws for the owners association are not proposed at this time. The covenants provide sufficient direction for the operation of the SUD until there are other developed portions. On yet another level, the building styles and functions, pedestrian and bicycle circulation solutions and the central parking courtyard are consistent with the Design Manual in the Master Plan. Altogether, the Phase 1 Subdivision is in conformance with the SUD Master Plan. 123 124 125 126 Page 3 (Subdivision Preliminary Plat Checklist – Prepared 11/26/03; revised 9/20/04; revised 5/2/05; revised 7/24/07, revised 11/14/11) SUBDIVISION PRELIMINARY PLAT CHECKLIST These checklists shall be completed and returned as part of the submittal.

Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 1 INTRODUCTION The following narratives serve as a summary report of operational impacts that could be associated with the proposed Phase 1 development of the South University Way Subdivision. The narrative figures and attachments encompass all of the intersections that would potentially be impacted by Phase 1 development, with the primary focus being centered on the intersection of Kagy and South11th Avenue. PROPOSED SITE DEVELOPMENT The proposed development property would be located south of Kagy Boulevard with the northern boundary parallel to Stadium Drive; the eastern boundary located along an extension of University Way; the southern boundary along an extension of Stucky Road from the west; and the western boundary along an internal subdivision street. This property is Phase 1, Lot 1 of a large tract of land east of South 19th Avenue and south of Kagy Boulevard that would eventually be developed at some point in the future. The property is currently zoned as “Residential Emphasis Mixed Use. Phase 1 development will accommodate approximately 480 resident units (bedrooms) contained within an apartment complex on 10.77 acres. In addition to the apartment complex, there would be two residences for occupation by facility staff. Also within the Phase 1 property boundary, it is anticipated that complimentary commercial buildings totaling 22,000 square feet of floor area will be built on 1.82 acres of Phase 1 land at some future date. This Traffic Impact Study (TIS) addresses potential impacts associated with full development of both residential and commercial land uses within the Phase 1 property boundary. Access to the property will initially be served by University Way (extension of S. 11th Avenue). In future development phases, it has been proposed that Stucky Road be connected to University Way, which would provide an alternative access to the Phase 1 property. The Traffic Impact Study addresses potential impacts to 142 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 2 the adjacent street system based upon the initial access conditions that only includes the University Way connection to Kagy Boulevard. EXISTING CONDITIONS Streets & Intersections Potentially impacted intersections located within a mile of the proposed development site are Kagy Boulevard intersections with: S. 19th Avenue, S. 11th Avenue, and S. 7th Avenue. The intersection of S. 19th Avenue and Stucky Road would have minimal potential for impacts associated with the planned access connection to Kagy Boulevard via University Way, but the S. 19th Avenue and Stucky intersection was included in the TIS analysis to serve as a baseline for future phased development traffic impact assessments. Kagy Boulevard is currently a three lane street with bike lanes in both directions. Kagy Boulevard extends from a termini point just west of S. 19th Avenue, past the MSU campus, to rural areas east of Bozeman. S. 19th Avenue extends from a point several miles south of the Kagy Boulevard intersection to an intersection with Interstate 90, on the northern end of Bozeman. South 9th Avenue has various lane combinations along its length. At its intersection with Kagy Boulevard, it provides two thru lanes in each direction with opposing left-turns lanes and additional right-turn lanes on the northbound and westbound approaches. South 11th Avenue extends from its intersection with Kagy Boulevard north, thru the MSU campus, to an intersection with Main Street. It currently operates with one lane for each direction of travel and includes bikes lanes on either side. At its intersection with Kagy Boulevard it accommodates a separate left-turn lane and a thru/right-turn lane on the southbound approach. The northbound approach to that intersection is University Way, which has the same lane configuration as the southbound approach. 143 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 3 South 7th Avenue extends from a point south of Kagy Boulevard to West Grant Street, approximately 0.35 miles north of Kagy. South 7th Avenue serves as a secondary access to surface parking lots, south of the MSU Student Union Building. In that capacity, travel demands are confined to a series of short term traffic surges throughout the day as classes change and events begin and end. The northbound approach to this intersection serves to access corporate offices with a finite demand in the am, pm, and noon hours. The southbound approach has a separate right-turn lane and a thru/left-turn lane, while the northbound approach has a single lane approach. A marked pedestrian crossing of Kagy Boulevard exists on the west side of the intersection. Existing Traffic Volumes Electronic traffic counters were used to count traffic on all approaches to South 11th Avenue and Kagy Boulevard in 2008 as a part of the traffic signal warrant study for that intersection. An hourly summary of traffic volumes from those counts can be found in the appendix. In order to update traffic counts, peak am and pm hour counts were taken in the first week of May 2011 at four key intersections and the results of those counts are illustrated in Figure 1. It should be noted that the peak am hour of traffic at the study intersections occurs between 8:00 and 9:00 am, which is one hour later than the average peak am hour at most intersections within the urban area. Since the turning movement counts were taken on different days of the week, a traffic count balancing routine was used to equalize the traffic demands to a common base. This routine determined that the Monday count at the intersection of Kagy Boulevard and S. 11th Avenue was approximately 8% lower than the counts at the adjacent intersections. Therefore, the Kagy and S. 11th Avenue volumes were adjusted upward and all other counts were rounded-up to the nearest 5 vehicles. Figure 2 illustrates the adjusted counts that represent the existing (2011) am and pm design hour volumes that were used as the baseline for capacity calculations within this study. 144 MARVIN & ASSOCIATES 1300 N.

Existing Capacity Capacity calculations were completed for the three intersections on Kagy Boulevard that would have potential impacts associated with development of the site without a connection between University Way and S. 19th Avenue. Table 1, above, summarizes the results of those calculations using Delay, Level- of-service (LOS), Volume to Capacity (v/c) ratios, and Vehicle Queue projections as Measures of Effectiveness (MOE). All intersections, approaches and 147 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 7 movements currently operate at LOS “C” or better except for the southbound left/thru lane on South 7th Avenue, which operates at LOS “E” with 35.1 seconds delay per vehicle during the peak PM hour, or approximately 0.1 seconds longer than the cutoff for LOS “D”. This approach lane only accommodates 35 vehicles during that hour of the day. DEVELOPMENT TRAFFIC PROJECTIONS Trip Generation The proposed apartment complex that would be constructed in Phase 1 is unlike any of the ITE Trip Generation Report land uses since it would be a cross between a Dormitory and a Mid-rise Apartment. The dwelling units in this development would actually be pods or bedrooms with common kitchen and laundry facilities on each floor or pod cluster. There would be one resident per pod or dwelling unit (bedroom) and one parking space per resident. In some respects this land use would be similar to a dormitory, except that this development would offer an independent life style with the ability to prepare meals on-site. The single occupancy and shared facilities would also make it different than a Mid-rise Apartment building, where more than one person can occupy each dwelling unit. An extensive search was completed to determine trip generation rates for college dormitories and only two case studies were found that would be representative of contemporary facilities. One study was for the New York State University at Oneonta. The traffic study was prepared by Delta Engineering for a new 200 bed dormitory facility. The trip generation rates were determined by collecting data from a similar facility at the University Of Albany, Empire Commons. The data collection only focused on the peak am and pm hours and comparisons were made to ITE Land Use Code 223 Mid-rise Apartments in their report. The other study was for Merrymount College in California, which was used for planning a 255 student dormitory. RBF Consulting performed the study and 148 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 8 determined the peak am and pm trip generation rates after adjusting for extraneous trips unrelated to the dormitories. Recognizing the bi-costal nature of the two reference studies, it was determined that a comparative study at the MSU Bozeman Campus would be necessary to determine if these rates would be applicable. Thus, all of the approaches to the 780 space parking lot for the Roskie-Hedges dormitory complex were counted between the hours of 3:30 and 5:30 pm on May 4, 2011. Between the hours of 3:30 and 4:30 pm it was discovered that the majority of vehicles had student occupants and the total number of vehicles entering and existing was greater than in the following hour period. In the following period, between 4:30 and 5:30 pm, it was noted that the majority of the staff spaces were vacated and significantly fewer student trips were made than in the preceding hour. Table 2, below, presents a summary of the trip generation rates for the Roskie/Hedges parking lot, the two referenced studies, and the ITE Code 223 Mid-rise Apartment trip generation rates. It was assumed that the Roskie/Hedges 3:30 to 4:30 time period counts represent the peak hour for the facility and that those rates could be compared to the Mid-rise Apartment peak hour facility rates. Table 2.

However, the peak am hour rate for MSU Bozeman could be extrapolated by comparing the MSU 4:00-6:00 pm 149 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 9 peak hour rates to the average of the referenced studies, in the same time period, and by comparing the relative differences between am and pm rates. Table 2 provides trip generation rates that were developed from the Roskie/Hedges counts and modified by using comparisons to the other reference sources. It was determined that a rate of 0.20 vehicular trips per resident would be a fair estimate for both the am and pm peak hour, considering the fact that in one case the pm hour rate is less than the am rate while the reverse is true for the other dormitory. For AWT, it was assumed that the peak pm hour would experience approximately 10% of the weekday total, similar to typical traffic variations on arterial streets. The resulting rate of 2.50 for the AWT would be slightly more than the Merrymont Study, but only 57% of the ITE Code 223 rate. Since all of the dormitory reference rates are for vehicular trips at facilities on or near college campuses and there was no data presented for pedestrian and bicycle trips, it is assumed that the difference between dormitories and Mid-rise Apartments, which could be located anywhere within an urbanized area, would be the mode choice. In order to estimate the bicycle and pedestrian mode trips, it was assumed that the difference between the ITE Code 223 AWT of 4.40 and the vehicular rate of 2.50 (4.40-2.50=1.90) would be ped/bike trips as shown in Table 2. For the 22,000 square feet of future commercial development, ITE Trip Generation Report Land Use Code # 814 – “Specialty Retail” was used because it normally provides a relatively conservative estimate of trip generation when specific businesses are unknown. The impact associated with complimentary commercial land uses to residential developments is difficult to quantify because of many unknowns. However, if the commercial facilities are matched to the needs of the residents, the net effect may be a reduction in external vehicular 150 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 10 traffic and an increase in localized pedestrian trips within the boundaries of the development. Table 3, below, summarizes the total vehicular and pedestrian/bike trip generation for initial and future development in Phase 1. The staff residences were treated as Single Family Dwelling Units (ITE Land Use Code 210) and would contribute approximately 19 external vehicular trips on the average weekday. The 480 residents units would generate approximately 1,200 external vehicular trips and 912 pedestrian/ bike trips on the average weekday. Future commercial development would add approximately 975 trips, but approximately 24% of those trips, or 234 trips, would be internal capture trips associated with pedestrian/bike modes made within the confines of the development boundaries. Therefore, the commercial land use would only add 741 average weekday vehicular trips external to the site. In total, this development would generate approximately 1,960 vehicular trips and 912 ped/bike trips that would be new and added to the existing traffic on the surrounding street system. Table 3.

Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 11 Trip Distribution The distribution of vehicular trips was based upon existing directional traffic movements at key intersections adjacent to the development site. Bike/ped distribution was based upon local area attractions and activities and travel distances. Approximately 40% of the vehicular trips would have origins and destinations to the north, on South 11th Avenue, and 40% would have origins and destinations to the north and west, using South 19th Avenue. Only 2% of the trips would be to the north and east, using South 7th Avenue, while 13% would have origins and destinations to the east, using Kagy Boulevard east of South 7th Avenue. The remaining 5% of total vehicular trips would have origins and destinations south of the development and accessed by South 19th Avenue. Pedestrian and bicycle trips would all be directed to and from the north. It was assumed, based upon campus attraction densities and walking routes, that 60% of the ped/bike trips would use South 11th Avenue, while the remaining 40% would use South 7th Avenue. It was also assumed that all ped/bike trips would cross Kagy Boulevard at the South 11th Avenue intersection signal. Traffic Assignment Site traffic assignments were completed using the trip generation projections in Table 2 and the trip distribution percentages discussed in the preceding section. The traffic assignment projection is based on the development of Phase 1 with the University Way access to and from Kagy Boulevard as the only access to Phase 1 development land uses. The traffic assignments shown in Figure 3 illustrate the peak am and pm hour site traffic (vehicular and bike/ped) at the key intersections, along with average weekday vehicular traffic on the street system links. 152 MARVIN & ASSOCIATES 1300 N.

Also shown in Figure 4 are the resultant AWT volumes and the percentage increase over existing traffic that would be attributable to the Phase 1 development. In this case, Kagy Boulevard, west of South 11th Avenue, would have the highest volume of site generated traffic and also the highest percentage increase of any of the area streets at 7%. It should be noted that, normally traffic impacts on streets that are less than 10% are not considered to be significant because daily traffic variations on any street routinely exceed 10%. 154 MARVIN & ASSOCIATES 1300 N.

Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 15 Capacity Capacity calculations (see Appendix) indicate that all approaches and all movements at the key intersections would operate at LOS “C” or better during both the am and pm hour periods, if the Phase 1 South University District development existed today. Table 4, below, present a summary of the MOE’s for each intersection and for each approach lane at each of the intersections. In comparing Table 4 to Table 1, it can be seen that there are slight variations in the LOS, delay and v/c ratios for individual lanes, but for overall intersection operations there would be no change in the LOS, less than a 1 second increase in delay, and no more than a 5% increase in v/c ratios. Queue lengths would vary within individual lanes, but none of the lanes would experience an increase in vehicle queues exceeding available storage or interfere with access movements adjacent to the intersections.

Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 16 Typically, a two lane streets in an urban environment can carry between 6,000 and 9,000 vehicle per day and still operate at LOS “C”. Three lane streets can carry up to 18,000 vehicles while 5 lane streets max-out at approximately 30,000. Thus, none of the surrounding streets’ capacity would be substantially impacted by the development of the Phase 1 property, as proposed. Future Traffic The City of Bozeman’s Capital Improvements Plan indicates that Kagy Boulevard will require reconstruction in the Year 2015. In order to determine if the additional traffic associated with this development would have operational impacts before the target year of 2015, it was necessary to project current traffic volumes to the year 2015 and add site generated traffic to year 2015 projections. From previous counts taken in 2008 and adjusting for seasonal variations, it was determined that traffic growth within the impacted area has been approximately 3% per year. Thus, traffic would increase on area streets by approximately 12.5% over the next four years. Figure 5, on the following page, illustrates the peak hour and average weekday traffic that would exists at key intersections and on street links in the year 2015, if Phase 1 of the subdivision were fully developed at that time. In comparison to Figure 4 traffic volumes, it appears that there would be between 1,500 and 1,750 more AWT on Kagy Boulevard in the year 2015. 157 MARVIN & ASSOCIATES 1300 N.

Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 18 Future Capacity Table 5, below, presents a summary of the MOE’s for each intersection and for each approach lane at each of the intersections. In comparing Table 5 to Table 4, it can be seen that there are slight variations in the LOS, delay and v/c ratios for individual lanes, but for overall intersection operations there would be no change in the LOS, less than a 3.5 second increase in delay, and no more than a 12% increase in v/c ratios. Queue lengths would vary within individual lanes, but none of the lanes would experience an increase in vehicle queues that would exceed available storage or interfere with access movements except for the westbound thru lane at Kagy and S 11th Avenue. The projected queue of 16 vehicles in that lane would exceed the available separation distance between S 11th Avenue and a local access street west of S 11th Avenue by approximately 3 vehicles. However, there is sufficient latitude in the signal timing to allow a queue reduction without degrading other movements entering the intersection.

Year 2015 Traffic Plus Site - Peak Hour Capacity Analysis Summary Intersection MOE NB SB EB WB 159 MARVIN & ASSOCIATES 1300 N. Transtech Way Billings, MT 59102 South University District Phase 1 Development Traffic Impact Study Page 19 CONCLUSIONS The development of the South University District Phase 1 Lot 1 property would not substantially impact the safety and efficiency of any of the area streets or intersections. The southbound, combination thru/left-turn movement at the intersection of Kagy Boulevard and South 7th Avenue currently operates at LOS “E” during the peak pm hour period. That movement currently has a pm peak demand totaling 35 vehicles and there would be no change in that volume as result of the proposed site development. Additional site traffic that would enter the intersection would increase the delay associated with that movement by 0.8 seconds per vehicle or 28.0 seconds for the entire hour, according to the HCM calculations. It should be noted that there are 42 pedestrian that use the crosswalk on the west side of the intersection and each pedestrian crossing creates a gap that the southbound thru/left-turn movement can use to enter the intersection. Thus, the LOS for that movement is likely higher than the calculations would indicate. Because South 7th Avenue is a local street serving drivers that are intimately familiar with traffic conditions and alternative routes are available, it would not be cost-effective to reconstruct or change the operation at this intersection. Future traffic (year 2015) on area streets is projected to increase by approximately 12.5% over current traffic volumes. Even with that amount of growth, in combination with full development of the South University District Phase 1 plan, all of the existing streets and intersections would operate at or above LOS C. Conflicts between the first local access street west of S 11th Avenue and the westbound thru lane queues would only have the potential to occur during a 15 minute period in the peak pm hour. If it is determined that this conflict is detrimental to operations, the signal timing could be adjusted to reduce westbound queue lengths, as a mitigating measure. 160 4FINAL MASTER PLANSITE MAP161
