HomeMy WebLinkAbout17 - Traffic Impact Study - Rosa Apartments Ph 2 & 3 Addendum April 5, 2017 blefin Adam Morse C&H Engineering traffic 1091 Stoneridge Drive services Bozeman, MT 59718 RE: Rosa Apartments TIS Addendum Dear Adam, The City of Bozeman has requested additional information regarding the traffic impacts from the Rosa Apartments residential development in Bozeman. In the review letter dated February 8, 2017,the City requested a review of the projected traffic impacts at the intersection of Durston Road and Cottonwood Road with additional traffic from the Lakes at Valley West Phases 3 &4 to develop a 15-year traffic projection for the intersection. ATS obtained data from the City of Bozeman regarding the Lakes at Valley West project and updated the traffic calculations for the projected traffic volumes. The developments taken into account for this project to develop the 15-year projection now include the Rosa Apartments (194 units),the Valley West subdivision(55 units), Phase III of the Boulder Creek Subdivision(115 units), Westbrook Phases 1-3 (62 units), Westbrook Phase 4 Lot 5 (42 multi-family units), and the Lakes at Valley West Phases 3 &4 (62 units). This data was used to recalculate the projected Level of Service at the Durston Road/Cottonwood Road intersection. This analysis suggests that the intersection will still function at LOS C with all of the developments anticipated in this area over the next 15 years. The detailed LOS summary is shown in the following table. See the attached traffic model and LOS calculations for more details. Future Level of Service Summary AM Peak Hour PM Peak Hour Intersection Delay Sec. LOS Delay (Sec.) LOS Durston Road & 20.4 C 20.2 C Cottonwood Road It is also anticipated that Cottonwood Road will be extended to the north to Baxter Road and Oak Street will be extended past Cottonwood Road within the next 15 years. These new road connections will significantly alter roadway traffic patterns throughout this area. The magnitude of these traffic volume changes require a regional traffic model to evaluate accurately. The Bozeman TMP which is currently nearing completion contains data regarding the existing and projected 2040 traffic conditions on roadways throughout Bozeman. The BTMP takes into account all anticipated land development projects which are expected to occur in this area of Bozeman over the next 25 years. The BTMP suggests that the intersection of Durston Road and Cottonwood Road will function at LOS F/E by 2040 even with a full expansion of Cottonwood Road to a five-lane collector road from Huffine Lane to Baxter Road. However,the BTMP also suggests that the roadways in this area will operate well within their functional capacities through 2040 130 South Howie Street Helena, Montana 59601 406-459-1443 (V/C of 0.43 to 0.79). Therefore, it is likely that the LOS issues projected by 2040 at this location will be correctable with minor intersection improvements which will be identified in the future. The City's plan to improve all of Cottonwood Road to a five-lane facility is appropriate based on the projected traffic volumes for this area. No additional roadway improvements specific to the Rosa Apartments would be necessary to address future traffic volumes. If you have any questions please feel free to contact me at 406- 459-1443.

EXECUTIVE SUMMARY The Rosa Apartments is a 179 unit complex which is proposed south of Oak Street near Rosa Way at 4951 Sherwood Way. The development would include ten buildings constructed in four phases over the next four years. At full build-out the development would produce up to 1,290 new daily trips in this area. As proposed, the Rosa Apartments will not create any roadway capacity problems along adjacent streets or intersection. All nearby intersections will continue to function at acceptable levels of service and no additional improvements will be necessary to serve the proposed development. Phase 1 of the development will not have direct access to Rosa Way. The developer should work with the City to develop an access plan for the site which complies with the City of Bozeman Subdivision Regulations while not necessitating the full construction of Rosa Way with Phase 1 of the project. The developer should also produce a follow-up traffic report describing the regional impacts of the ongoing development in this area and what traffic controls may be necessary to facilitate the future road network. B. PROJECT DESCRIPTION This document studies the possible effect on the surrounding road system from a proposed residential developments located north of Durston Road between Twin Lakes Avenue and Rosa Way in Bozeman, Montana. The document identifies any traffic mitigation efforts that the development may require. The site is located '/z mile north of Durston Road and one block west of Cottonwood Road. The property would be developed to include up to 179 new residential apartment units in ten buildings. Based on the City of Bozeman Subdivision Regulations, the developers must study all effected intersections within '/z mile of the proposed development which includes the intersections of Durston Road with Rosa Way and Cottonwood Road. Although this development will include the construction of a portion of Oak Street,the section of road will not connect to the existing sections of Oak Street east of Flanders Mill Road until further development occurs. C. EXISTING CONDITIONS The proposed development property currently consists of an 8-acre parcel of undeveloped land located north of Sherwood Way between Twin Lakes Avenue and Rosa Way. The site is located just west of the Flanders Creek Subdivision and just east of the Boulder Creek subdivision. The topography in this area slopes to the north. A traffic signal was installed at the intersection of Cottonwood Road and Durston Road in the spring of 2016 which has resolved many of the Abelin Traffic Services 1 November 2016 Rosa Apartments Traffic Impact Study Bozeman,Montana traffic related problems in this area associated with the continuing development of the adjacent properties. See Figure I for a location map of the proposed development. Fi ure 1- Pro osed Develo ment Site I Qse - ' P f 1 it l O�• c .rr 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 years 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 Laurel Parkway and has designated bike lanes. All cross-streets between Laurel Parkway and Flanders Mill Road are controlled by STOP signs, except the intersection with Cottonwood Road which was recently signalized to correct operational issues and improve capacity. The roadway has a posted speed limit of 35 MPH and currently carries 7,500 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 30-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. The City of Bozeman has plans to expand Cottonwood Road between Babcock Street and Durston Road in 2018 which will include intersection widening at Durston Road. Abelin Traffic Services 2 November 2016 Rosa Apartments Traffic Impact Study Bozeman,Montana Twin Lakes Avenue is a north/south local road that passes along the east side of the proposed development site. The road has a paved width of 32 feet and is STOP controlled on all cross streets. Sherwood Way is an east/west local road that passes along the south side of the proposed development site. The road has a paved width of 32 feet. All cross streets with Sherwood Way are STOP controlled. Rosa Way is a north/south local road that is currently built to the southwest corner of the proposed apartment complex. The road has a paved width of 32 feet and is STOP controlled on all cross streets. Rosa Way connects to Durston Road 1,800 feet to the south. Traffic Counts In November 2016 Abelin Traffic Services (ATS) collected turning movement count data at intersections along Durston Road as requested by the City of Bozeman. These counts included morning and evening counts at the intersection of Durston Road with Rose Way. Additional traffic data for the intersection of Durston Road with Cottonwood Road was obtained from the 2016 Bozeman Transportation Master Plan. The raw traffic data is included in Appendix A of this report. Additional Developments Several additional developments are currently underway in this area which will add traffic to the subject intersections. These projects include the Valley West subdivision (55 units), Phase III of the Boulder Creek Subdivision (115 units), Westbrook Phases 1-3 (62 units), and Westbrook Phase 4 Lot 5 (42 multi-family units). Traffic from these projects was taken into account with the future traffic projections for the Rosa Apartments. 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 6.8. Intersections are graded from A to F representing the average delay that a vehicle entering an intersection can expect, with "A"being the least delay. Typically, a LOS of C or better is considered acceptable for peak-hour conditions. Table 1 shows the existing 2016 LOS for the AM and PM peak hours without the traffic from the proposed Rosa Apartments and the other planned developments in this area. Abelin Traffic Services 3 November 2016 Rosa Apartments Traffic Impact Study Bozeman,Montana The LOS calculations are included in Appendix C. The table shows that these intersection are currently operating without significant. The installation of the traffic signal at the intersection of Durston Road and Cottonwood Road has improved the operations at this intersection and has provided significant reserve capacity to accommodate ongoing growth. No road improvements are recommended at this time for any of the study intersections. Table 1 —2016 Level of Service Summary AM Peak Hour PM Peak Hour Intersection Delay (Sec.) LOS Delay (Sec.)

PROPOSED DEVELOPMENT The development currently under consideration for this site includes 8 acres of land located north of Sherwood Way which would be developed into a 170 unit apartment complex. The development would ultimately include ten apartment buildings constructed in five phases and is expected to be completed in 2020. Access to the development sites would be provided through new approaches onto Twin Lane Avenue to the east and Rosa Way to the west. Traffic from the site would filter south to reach Durston Road and the other areas of Bozeman. A section of Oak Street will be constructed along the northern edge of the development site which will connect with a section of Oak Street planned with construction with the Boulder Creek subdivision. Ultimately it is likely that Oak Street will become the primary access road to the site from the east, but it is not known when this connection may occur. The Rosa Apartments site plan is shown in Figure 2. 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, Ninth 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, when completed the development would produce 99 AM peak hour trips, 120 PM peak hour trips, and 1,290 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 and Durston Road to the south and west to reach other destinations. Traffic is expected to distribute onto the surrounding road network as shown on Figure 3. Figure 3 —Trip Distribution Proposed Development Site 5% Durston Road 10 50% W 0 0 0 3 c 0 0 45% U 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 Rosa Apartments is shown in Table 3. These calculations are based on the projected model volumes included in Appendix B of this report and includes the projected traffic from the other proposed projects in this area. Abelin Traffic Services 6 November 2016 Rosa Apartments Traffic Impact Study Bozeman,Montana Table 3 indicates that the construction of the Rosa Apartments and the other planned area projects will not cause any roadway capacity problems at locations along Durston Road. All intersections will continue to function at an acceptable LOS through completion of the project. The existing traffic control configurations along Sherwood Way (STOP controls) will provide efficient access to Rosa Way and Cottonwood Road and should be maintained. It should be noted that the intersection of Durston Road with Cottonwood Road would be nearing capacity along Cottonwood Road by 2020 with the completion of these developments under the current road configuration. However, the City of Bozeman plans to widen Cottonwood Road south of Durston Road and add additional lanes at the intersection in 2018 which will significantly improve the capacity at the intersection and ensure efficient roadway operations for continued development in this area. Future road connection to Oak Street and Cottonwood Road will have a significant impact on the overall traffic flow patterns and traffic control needs in this area. It would be valuable for the developer to provide information to the City regarding the overall impacts of the full build-out of this area in relation to the future road network configuration and traffic controls.

The connection to Rosa Way would not be necessary for efficient traffic flow in and out of the development for Phase 1. However, a secondary emergency or fire access may be necessary for Phase 1 to comply with the City of Bozeman Subdivision Regulations for block length and emergency access. This requirement could be accommodated by constructing portions of Rosa Way as an emergency access only with a gravel surface in Phase 1 which would then be formalized at primary access point for later phases. The developer should work with the City to develop an access plan which would provide continuous emergency access to the development without necessarily requiring the full construction of Rosa Way with Phase 1. H. IMPACT SUMMARY & RECOMMENDATIONS As proposed, the Rosa Apartments will not create any roadway capacity problems along adjacent streets or intersection. All nearby intersections will continue to function at acceptable levels of service and no additional improvements will be necessary to serve the proposed development. Abelin Traffic Services 7 November 2016 Rosa Apartments Traffic Impact Study Bozeman,Montana Phase 1 of the development will not have direct access to Rosa Way. The developer should work with the City to develop an access plan for the site which complies with the City of Bozeman Subdivision Regulations while not necessitating the full construction of Rosa Way with Phase 1 of the project. The developer should also produce a follow-up traffic report describing the regional impacts of the ongoing development in this area and what traffic controls may be necessary to facilitate the future road network.
