EXECUTIVE SUMMARY As proposed, the Boulder Creek and Westbrook developments will not create any new roadway capacity problems along Durston Road. The intersection of Durston Road and Cottonwood Road is currently operating at a poor LOS in the PM peak-hour and the traffic from these developments will add to this problem. It is recommended that a left-turn be installed at this intersection for westbound traffic and that the intersection be converted to four-way STOP control. Alternatively this intersection could be improved by the installation of a modem roundabout. All other nearby intersections will continue to function at acceptable levels of service and no other additional improvements will be required along Durston Road to serve the proposed developments. B. PROJECT DESCRIPTION This document studies the possible effect on the surrounding road system from two proposed residential developments located north of Durston Road between Laurel Parkway and Rosa Way in Bozeman, Montana. The document also identifies any traffic mitigation efforts that the development may require. The site is located north of Durston Road V4mile west of Cottonwood Road. The property would be developed to include up to.233 new residential units. Based on the City of Bozeman Subdivision, Regulations, the developers must study all effected intersections within V2 mile of the proposed development which includes the intersections of Durston Road with Laurel Parkway, Rosa Way, Cottonwood Road, and Flanders Mill Road. Although this development will include the construction of a portion of Oak Street,the section of road I will not connect to the existing sections of Oak Street to east and will not provide access to the development site until additional properties in this area are developed to the east. A traffic impact study was prepared for this project in 2007 which was,then called Laurel Glen Phases 3 & 4. The 2007 traffic study, which anticipated the construction of 270 residential units on the property,recommended the construction of a designated left-turn lane along Durston Road at Cottonwood Road, oad, and that four-way STOP controls be installed at the intersections of Durston Road with Ferguson Road(completed) and Cottonwood Road. C. EXISTING CONDITIONS The proposed development property currently consists of a 70-acre parcel of undeveloped land located north of Durston. Road between Laurel Parkway and Rosa Way. The site is located Abelin Traffic Services Z November 2013 Boulder CreeklWestbrook Traffic Impact Study Bozeman,Montana between.the Laurel Glen Phase 2 Subdivision and the Traditions Subdivision. The topography in this area is flat. See Figure I for a location map of the proposed development. Fi aJr t- Pro os d l v Co meet Site . . r Adjacent Roadways Durston Road is a two-way east/west minor arterial route that provides access to the residential areas to the west of Bozeman. In recent year much of the road has been reconstructed to accommodate development in this area. Currently the road has a three-lane cross-section with a paved width.of 46-feet east of Cottonwood Road and two-lanes paved at 31 feet west of Cottonwood Road. Durston Road also has designated bike lanes. All cross- street between Laurel Parkway and Flanders Mill Road are controlled by STOP signs. The roadway has a posted speed limit of 35 MPH and currently carries 8,600 Vehicles Per Day (VPD). Laurel Parkway is a north/road that was constructed to serve the different phases of the Laurel Glen development. This roadway was constructed with a wide median, turn lanes, and roundabouts at some intersection to provide capacity for future development and future road connections. The roadway has a posted speed limit of 25 MPH and currently carries 2,800 Vehicles Per Day(VPD). Cottonwood Road is a principal arterial north/south route that provides access to the residential developments to the north and Huffine lane to the south. The road has a two-lane cross-section with a paved width of 28-feet near Durston Road. The road has a posted speed limit of 25 MPH north of Durston Road and 40 MPH south of Durston Road. Cottonwood Road currently carries 550 VPD north of Durston Road. . Abelin Traffic Services 2 Noveinber 2013 Boulder CreeklWestbrook Traffic Impact Study Bozeman,Montana Flanders Mill Road in a north/south two-lane road which provides access north to Baxter Lane. The road currently has a paved width of 27 feet and a posted speed limit of 40 MPH. Flanders Mill Road currently carries 2,500 VPD north of Durston Road. Traffic Counts In July 2013 Abelin Traffic Services (ATS) collected turning.movement count data at intersections along Durston Road, as requested by the City of Bozeman. These counts included the intersections of Durston Road with Laurel Parkway, Rose Way, Cottonwood Road, and Flanders Mill Road. ATS also collected 24-hour ADT data on Laurel Parkway, Flanders Mill, and Durston Road. The raw traffic data is included in Appendix A of this report. Level of Service Using the data collected for this project, ATS conducted a Level of Service (LOS) analysis at area intersections. This evaluation was conducted in accordance with the procedures outlined in the Transportation Research Board's Highway Capacity Manual (HCM) - Special Report 209 and the Highway Capacity Software (HCS) version 5.3. Intersections are graded from A to F representing the average delay that a vehicle entering an intersection can expect. Typically, a LOS of C or better is considered acceptable for peak-hour conditions. Table I -2013 Level of Service Summary AM Peak Hour PM Peak Hour Intersection D2!ay Sec. LOS Delay (Sec.)

The LOS calculations are included in Appendix C. Table I shows that most of the existing intersections along Durston Road are currently operating within acceptable limits. However, the intersection of Cottonwood Road and Durston Road is currently experiencing excessive evening peak-hour delay. This issue Abelin Traffic Services 3 November 2013 Boulder Creek/Westbrook Traffic Impact Study Bozeman,Montana will need to be addressed regardless of any additional development within this area. If this intersection were converted to a four-way STOP controlled intersection it would function at LOS C.with 16.8 seconds of delay in the PM peak-hour. If an additional left- turn lane were added to this intersection for westbound traffic, the overall intersection delay would,drop to 14.0 seconds. D. PROPOSED DEVELOPMENT The development currently under consideration for this site includes 70 acres of land located north of Durston Road which would be developed into two residential subdivisions, The Westbrook Subdivision would be located just north of Durston Road and the Boulder Creek Subdivision would be located just north of Annie Street. The Westbrook Subdivision would include 118 single-family residential units. A total of 115 single-family residential units are proposed in the Boulder Creek Subdivision for a total of 233 new residential units. It should be noted that this is a significant decrease for the 270 residential units previously proposed for this property. The developments would each have designated parks and sidewalks throughout the properties. Access to the development sites would be provided through a variety of new connections onto Laurel Parkway,Rosa way, and North Cottonwood Road. Presently these three streets would be the only access points from the developments to Durston Road and the City of Bozeman. As this area continues to develop in the future it is likely that additional road connections will be provided to the north and east. The Westbrook and Boulder Creek development are shown in Figures 2 &3. E. TRIP GENERATION AND ASSIGNMENT ATS performed a trip generation analysis to determine the anticipated future traffic volumes from the proposed development using the trip generation, rates contained in Trip Generation (Institute of Transportation Engineers, Seventh Edition). These rates are the national standard and are based on the most current information available to planners. A vehicle "trip"is defined as any trip that either begins or ends at the development site. ATS determined that the critical traffic impacts on the intersections and roadways would occur during the weekday morning and evening peak hours. According to the ITE trip generation rates, at full build-out the developments would produce 175 AM peak hour trips, 235 PM peak hour trips, and 2,230 daily trips. See Table 2 for detailed trip generation information.

TRIP DISTRIBUTION The traffic distribution and assignment for the proposed subdivisions was based upon the existing ADT volumes along the adjacent roadways and the peak-hour turning volumes. Based on field observations, half of the traffic from the development site will use Durston Road to reach areas to the east in Bozeman. The rest of the traffic will use Cottonwood Road,Flanders Mill Road, and Durston Road to reach other destinations. Traffic is expected to distribute onto the surrounding road network as shown on Figure 4. Figure 4—Trip Distribution 5% 0 Proposed Development Site is a LL Durston Road 50% ca 0 4U1/0 G. TRAFFIC IMPACTS OUTSIDE OF THE DEVELOPMENT Using the trip generation and trip distribution numbers, ATS determined the future Level of Service for the area intersections. The anticipated intersection LOS with the Westbrook and Boulder Creek Subdivisions is shown in Table 3. These calculations are based on the projected model volumes included in Appendix B of this report. Abelin Traffic Services 7 November 2013 Boulder CreeldWestb Bozeman,Montana Table 3 indicates that the construction of the Boulder Creek and Westbrook Subdivisions will not cause any additional roadway capacity problems at locations along Durston Road. The intersection of Cottonwood Road and Durston Road is currently operating at a poor LOS and the Bounder Creek/Westbrook developments will contribute to the need for improvements at this location. There are several options for improving the capacity and LOS at the intersection of Durston Road and Cottonwood Road. If the intersection were modified to a four-way STOP controlled intersection with its current lane configuration the LOS would improve to D with 29.3 seconds of peak-hour delay. If an additional left-turn lane were added for westbound traffic with the four- way STOP control, the overall intersection delay would improve to 19.3 seconds (LOS C) and the intersection would have considerable reserve capacity. With the current road layouts in this intersection, a left-turn lane could be created by widening only the west leg of Durston Road and re-striping the intersection. Alternatively,the capacity related issues at this intersection could be addressed by constructing a modern roundabout at this location. There is sufficiently area to construct a roundabout in this intersection and this type of traffic control is becoming common in this part of Bozeman. If constructed, a roundabout would operate at LOS B with 11.5 seconds of delay and would provide sufficient capacity for this intersection well into the future, Table 3 —Level of Service Summary With the Boulder Creek/Westbrook Developments AM Peak Hour PIVI Peak Hour Intersection Delay (Sec.)

IMPACT SUMMARY & RECOMMENDATIONS As proposed, the Boulder Creek and Westbrook developments will not create any new roadway capacity problems along Durston Road. The intersection of Durston Road and Cottonwood Road is currently operating at a poor LOS in the PM peak-hour and the traffic from these developments will add to this problem. It is recommended that a left-turn be installed at this intersection for westbound traffic and that the intersection be converted to four-way STOP Abelin Traffic Services 8 November 2013 Boulder CreeklWestbrook Traffic Impact Study Bozeman,Montana control. Alternatively this intersection could be improved by the installation of a modern roundabout. All other nearby intersections will continue to function at acceptable levels of service and no other additional improvements will be required along Durston Road to serve the proposed developments.
