3 A. EXECUTIVE SUMMARY The Highline Development Traffic Impact Study Columbia Falls, Montana The Highline development is a 13.8acre, 208 unit residential apartment complex located east of 3 rd Avenue in Columbia Falls, MT. At full build-out the project will produce up to 1,383 daily trips within the area. As proposed, The Highline development will increase traffic along 3 rd Avenue and 9 th Street but will not create any roadway capacity problems within the area under normal seasonal traffic conditions. Higher peak summer traffic conditions within the area will create some traffic congestion issues at the intersection of Highway 2 and 3 rd Avenue. It would be desirable to create separated southbound left- and right-turn lanes at the intersection of Highway 2 with 3 rd Avenue to improve traffic flow through the intersection under peak summer traffic conditions with Phase 2 of this development. B. PROJECT DESCRIPTION This document studies the possible effects on the surrounding road system from a proposed residential development located east of 3 rd Avenue in Columbia Falls, Montana. The development includes 208 residential apartment units on 13.8 acres of property on the eastern side of Columbia Falls. This document identifies any traffic mitigation efforts that the development may require. C. EXISTING CONDITIONS The proposed development property currently consists of a 13.8-acre parcel of undeveloped land located at the east end of Bills Lane. Bills Lane is accessed from 3 rd Avenue to the west. The topography in this area is mostly flat. See Figure 1 for a location map of the proposed development. Adjacent Roadways US Highway 2 is a five-lane east/west principal arterial highway which extends from Whitefish through Columbia Falls to Hungry Horse. Near 3 rd Street the road has a paved width of 96 feet with 12-foot driving lanes and sidewalks. The posted speed limit through Columbia Falls is 35 MPH and increases to 45 MPH at the city limits between Nucleus Avenue and 3 rd Avenue. Traffic data from MDT indicates the highway carried 14,300 VPD in Bills Lane is a local east/west route with an urban cross-section and a concrete sidewalk on the north side of the road. The lane has a paved width of 28 feet and a total length of 300 feet. Bills Lane provides access to five residential duplexes along the north side of the road. Bills 100

4 Lane is controlled with STOP signs at the intersection with 3 rd Avenue. Figure 1- Proposed Development Site The Highline = Study Intersection 3 rd Avenue East is a local north/south route which extends north from Highway 2. The road provides access to residential areas north of Highway 2. The road has a rural cross-section and a paved width of 26 feet with a posted speed limit of 25 MPH. 3 rd Avenue has an eight-foot paved pedestrian/bike trail that runs along the east side of the road south of 9 th Street and crosses to the west side of the road north of 9 th Street. 3 rd Ave is STOP controlled at the intersection with Highway 2. Traffic data collected by ATS in 2018 indicates the roadway carries 600 VPD. Nucleus Avenue/ Hwy 486 is a north/south route that extends north from Highway 2 in Columbia Falls and provides access to the commercial areas in the downtown area before extending into the Flathead National Forest. The road has a posted speed limit of 25 MPH through Columbia Falls. Nucleus Avenue has an urban three-lane cross-section at the intersections with 9th Street and a paved width of 55 feet. The intersections of Nucleus Avenue with Highway 2 is controlled with an actuated traffic signal. According to MDT Nucleus Avenue carried 7,500 VPD in th Street East is a local east/west route that provides access to the residential areas and a city park north of Highway 2. The road has a paved width of 22 to 26 feet. The intersection with 3 rd Avenue is controlled by STOP signs on 9th Street. The road has a short inclined section as 101

5 it approaches a STOP controlled T-intersection at Nucleus Avenue. Traffic data collected by ATS in 2018 indicates daily traffic volumes of 200 VPD on 9 th Street. Traffic Data Traffic data for this analysis was collected in June 2018 for the intersections near the proposed development site. Intersection traffic data was collected for the AM and PM peak hours at the intersections of Highway 2 with Nucleus Avenue and 3 rd Avenue and at the intersection of Nucleus Avenue with 9 th Street. Additional 48-hour traffic counts were conducted on 3 rd Avenue and 9 th Street. This data was reviewed for seasonal variation patterns in accordance with the data collected from MDT s annual count stations on Highway 2 west of Kalispell (Station A-24) and Highway 2 north of Columbia (Station A-60). These count stations indicated that data collected in June is 119%-149% of the AADT (Average Annual Daily Traffic) volume in this area. For the purposes of this report the seasonal correction factor of 119% was used to assess the average peak-hour traffic conditions for the area intersections. The raw data is included in Appendix A. Generally, traffic analysis is performed using annual average traffic volumes unless significant seasonal variations exist. In this case, traffic volumes in the Flathead Valley can peak at 124% to 210% of the annual average during the month of July. While it may not be necessary to design roadways based on the heaviest use conditions, these conditions should be considered when developing roadway improvement plans. Historic Traffic Data Abelin Traffic Services obtained historic traffic data for area roadways. This data is presented in Table 1. The traffic data history for this area indicates that traffic volumes on the roadways within Columbia Falls have increased at an annual rate of 1.5% over the last ten years. Traffic volumes on Nucleus Avenue have increased at a lower rate than traffic volumes on Highway 2.

6 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 utilized the Highway Capacity Software (HCS) version 7.5. 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 2 shows the existing LOS for the AM and PM peak hours without the traffic from the proposed development. The LOS calculations are included in Appendix C. The table shows that the existing intersections are currently operating within acceptable limits and are operating with minimal delay under average traffic conditions. No intersection modifications are currently needed in this area to improve capacity. No detailed LOS calculations were made for the intersection of 9 th Street and 3 rd Avenue due to the relatively low traffic volumes on these roads. Based on the peak-hour traffic volumes recorded on 9 th Street and 3 rd Avenue, the LOS at this two-way STOP controlled intersection is LOS A.

PROPOSED DEVELOPMENT The development currently under consideration for this site includes 13.8 acres of land located east of 3 rd Avenue which would be developed into a 208-unit residential apartment complex. The development would include six apartment buildings located at the east of Bills Lane. Access to The Highline residential subdivision will be provided through a connection with Bills Lane to the west. Although the development will be located adjacent to Park Avenue to the east, no connection will be made between The Highline and Park Avenue due to an existing area of wetlands between the properties. The Highline development will include nine acres of open space and a central common with a playground and tennis courts. The project will be constructed in three phases with 1/3 of the units (two building) constructed in each phase. It is anticipated that the first phase of The Highline will be fully constructed Subsequent phases will be constructed based on occupancy and demand. The Highline residential development site plan is shown in Figure

8 E. TRIP GENERATION AND ASSIGNMENT ATS performed a trip generation analysis to determine the anticipated future traffic volumes from the proposed developments using the trip generation rates contained in Trip Generation (Institute of Transportation Engineers, Tenth 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 development would produce 106 AM peak hour trips, 129 PM peak hour trips, and 1,383 daily trips. See Table 3 for detailed trip generation information. Land Use Units Table 3 - Trip Generation Rates AM Peak Hour Trip Ends per Unit Total AM Peak Hour Trip Ends PM Peak Hour Trip Ends per Unit Total PM Peak Hour Trip Ends Weekday Trip Ends per Unit Total Weekday Trip Ends Apartment (ITE # 220) ,383 F. TRIP DISTRIBUTION The traffic distribution and assignment for the proposed development was based upon the existing ADT volumes along the adjacent roadways and the peak-hour turning volumes. Traffic is expected to distribute onto the surrounding road network as shown on Figure 3. 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 Highline is shown in Table 4. The LOS calculations are included in Appendix C of this report. 105

9 Figure 3 Trip Distribution 24% 1% 50% Nucleus Avenue 9 th Street 3 rd Avenue The Highline 25% Table 4 indicates that the construction of The Highline residential subdivision will not cause any roadway capacity problems along Highway 2 or Nucleus Avenue under normal traffic conditions. The development will increase traffic on the local road network by 10% at the intersections on Highway 2, but all intersections will continue to function at LOS C or better at full buildout of the project under average annual traffic conditions. Traffic volumes on 3 rd Avenue will increase to approximately 2,000 VPD, but it is generally expected that local urban roadways can handle over 5,000 VPD. Peak-hour traffic volumes on 9 th Avenue will increase to 500 VPD. Note that the projected LOS at the intersection of Nucleus Avenue and 9 th Street improves slightly with the proposed development due to an increased number of right-turning vehicles driving down the average delay from the low-volume approach.

LOS Nucleus Ave. & 9 th St B 12.1 B Nucleus Ave. & Hwy B 12.6 B Hwy 2 & 3 rd Ave B 16.2 C 106

10 A peak season analysis was also performed by increasing traffic volumes at the affected intersection by 100 percent to evaluate if any LOS issues will occur under heavy summer traffic loading. This analysis indicated that traffic operations at the intersection of Highway 2 with Nucleus Avenue will be largely unaffected. However, the intersection of Highway 2 and 3 rd Avenue may fall to LOS E under these conditions It would be desirable to create separated southbound left and right-turn lanes at the intersection of Highway 2 with 3 rd Avenue to help improve traffic flow through the intersection under peak summer traffic conditions. This improvement will be necessary to help moderate peak summer demand past Phase 1 of the development. H. IMPACT SUMMARY & RECOMMENDATIONS As proposed, The Highline development will increase traffic along 3 rd Avenue and 9 th Street but will not create any roadway capacity problems within the area under normal seasonal traffic conditions. Higher peak summer traffic conditions within the area will create some traffic congestion issues at the intersection of Highway 2 and 3 rd Avenue. It would be desirable to create separated southbound left- and right-turn lanes at the intersection of Highway 2 with 3 rd Avenue to improve traffic flow through the intersection under peak summer traffic conditions with Phase 2 of this development. 107
