Both of these streets are classified as minor arterials. There are 67 residential condominium units (ITE Use 230) planned for this subdivision along with 87 detached senior adult housing units (ITE Use 251) resulting in a gross density of 7.06 units per acre. Direct access to the site is located on Locust Grove Road, approximately 660 feet north of Ustick Road. Another access is to the north on Heritage View Avenue through the Heritage Commons Subdivision. A future third access for the site south to Ustick Road may be through the Wanda's Meadow Subdivision on Yellow Peak Lane. That potential connection is currently blocked by an eight -foot strip of land owned by a third party. SUMMARY OF FINDINGS 1. The site will generate 938 daily trip ends with 71 AM peak -hour trips and 94 PM peak -hour trips. 2. The intersection of Ustick Road and Locust Grove Road presently operates at LOS C with an average delay of 34.7 seconds during the AM peak hour and 30.4 seconds during the PM peak. No approach to the intersection operates below LOS D. In 2010, without the traffic added by the subdivision, the Ustick/Locust Grove intersection will operate at LOS D during the morning and evening peak hours; the average delay will be 49.0 seconds and 41.5 seconds, respectively. The westbound left turn will operate at LOS F in both the morning and evening peak hours. The Ustick/Locust Grove intersection with site traffic added in 2010 will operate at LOS D during the morning and evening peak hours; the average delay will be 51.2 seconds and 42.3 seconds, respectively. The westbound left turn will operate at LOS F in both the morning and evening peak hours. — Chalet Marseilles Subdivision � J-U-B ENGINEERS, Inc. 3. The E Monet Street intersection at Locust Grove Road is expected to operate at LOS B with 13.6 seconds average delay per vehicle in the PM peak and 13.3 seconds delay in the AM peak. If the connection to Yellow Peak Avenue is not made, the intersection will still operate at LOS B with an average delay of 12.6 seconds in the PM peak and 13.0 seconds without the connection. 4. If the road connection is made between Chalet Marseilles and Wanda's Meadow Subdivision, Lillyturf Avenue at Ustick Road will operate at LOS C with 20.1 seconds average delay per vehicle in the PM peak and at LOS B with 14.7 seconds delay in the AM peak. RECOMMENDATIONS 1. Construct the connection between Chalet Marseilles and Wanda's Meadow Subdivisions at the earliest possible time. This connection will reduce the number of vehicle trips through the Ustick/Locust Grove intersection. It may also keep the traffic volume on Park Commons Avenue below in the Heritage Commons Subdivision below the 1,000 vehicles per day local street threshold. 2. Consider relocating Monet Street further south along Locust Grove Road to obtain a 125-foot minimum offset from Summerheights Drive. This will reduce conflicts between the traffic from these two streets as well as the adjacent church driveway. 3. Coordinate site improvement to facilitate installation of a southbound through -lane at the intersection of Ustick Road and Locust Grove Road. This lane is needed to maintain all movements within the intersection above LOS F. This improvement is needed with or without the traffic generated by the Chalet Marseilles Subdivision. STUDY OBJECTIVE The purpose of this study is to assess the traffic impacts of the proposed Chalet Marseilles Subdivision on the local road system and evaluate the ability of the system to accommodate the site -generated traffic. This study is to be done in conformance to Ada County Highway District's policies for traffic impact studies. _ Chalet Marseilles Subdivision 2 J-U-B ENGINEERS, Inc. SITE DESCRIPTION Chalet Marseilles Subdivision is a 21.81-acre residential development located at the northwest corner of Ustick Road and Locust Grove Road in Meridian, Idaho (Figure 1). At build -out, the development will consist of 87 senior adult housing units and 67 residential condominium units comprised primarily of four-plex buildings. The gross density will be approximately 7.1 dwellings per acre. Construction will be done in two phases with build -out projected to be in the year 2010. Chalet Marseilles will connect to Locust Grove Road approximately 660 feet north of Ustick Road. The subdivision will also connect to the Heritage Commons Subdivision to the north via Heritage View Avenue. It is likely that Chalet Marseilles will also connect to Ustick Road indirectly through Wanda's Meadow Subdivision via Yellow Peak Avenue. Presently, another property owner owns an eight -foot strip of land that divides the two subdivisions and prevents the connection. It is _ expected that this connection will be made when that parcel of land is developed in the future. _. Chalet Marseilles Subdivision 3 J-U-B ENGINEERS, Inc. Figure 1.

Determine existing traffic conditions and assess operational characteristics of the Ustick Road/Locust Grove intersection. 2. Establish baseline conditions and evaluate the intersection capacities based on the COMPASS 2010 Long Range Transportation Model. 3. Estimate traffic volumes generated by the proposed development using the ITE Trip Generation Manual and distribute the trips to the approach road and adjacent arterial intersections. 4. Evaluate traffic conditions for baseline plus site generated traffic. Chalet Marseilles Subdivision 5 J-U-B ENGINEERS, Inc. 5. Identify capacity limitation of the existing roadway and suggest improvements to mitigate those limitations. Facilities to be evaluated include the intersection of Ustick Road at Locust Grove Road, Locust Grove Road at Monet Street, and Ustick Road at Lillyturf Avenue. ASSUMPTIONS The following are the assumptions used in this traffic study to analyze traffic conditions: 1. The 2010 traffic volume on Ustick Road in the vicinity of the proposed development is approximately 13,400 vehicles per day. This value was determined by using project growth rate through 2030 from COMPASS "Trend" model and applying it to the 4/7/05 ACHD count of 10,975. The projected growth rate is approximately 4% per year. w 2. The 2010 traffic volume on Locust Grove Road in the vicinity of the proposed development is approximately 10,125 vehicles per day. This value was determined by using project growth rate through 2030 from COMPASS "Trend" model and applying it to the 12/13/05 ACHD count of 9,399 in the vicinity of the proposed development. The projected growth rate on Locust Grove, north of Ustick is approximately 1.5% per year. 3. This project is expected to be built out by 2010. The COMPASS "Trend" Long Range Transportation Model prediction was used because the traffic volumes predicted are higher than the "Choice" model, thereby providing a more conservative analysis. TRAFFIC VOLUMES The baseline level of service for the study area was calculated for the 2010 traffic conditions. This .- provides the basis for determining the traffic impacts created by the development. Existing roadway geometry and level terrain classification were used in the analysis. Table 5 2010 Traffic Volumes Street Daily AM Peak PM Peak Usti * Road 13400 947 952 Locust Grove Road 10125 810 911 _, Chalet Marseilles Subdivision 6 J-U-B ENGINEERS, Inc. The COMPASS model shows the 2010 traffic volumes on Locust Grove Road to be less than the volumes recorded in 2005 by ACHD. The growth rate predicted between the 2010 model and the 2030 model were used to calculate 2010 traffic volumes for Locust Grove using the 2005 traffic counts as a base year. Directional splits and peak -hour volumes were calculated using the existing splits and peak -hour percentage of total daily traffic. Site Generated Traffic t The vehicle trips to be generated by the proposed development were determined using the latest edition of the ITE Trip Generation Manual (7th Edition). There are 87 proposed Senior Adult Detached Housing units (Use 251) and 67 Residential Condominium/Townhouse units (Use 230). Using the fitted curve equation for total daily trips generated, a total of 938 vehicle trips per day will be generated by this site. AM peak -hour trips were calculated to be 71 trips and PM peak -hour trips were calculated to be 94 total trip ends. No trip capture is assumed for this analysis. Trip Distribution Existing demographics and directional traffic flows were used to determine future traffic distributions on Ustick Road and Locust Grove Road. The predominant direction of travel from the Chalet Marseilles Subdivision will be to the south and west. The primary access will be Monet Street at Locust Grove Road. A few trips will utilize Heritage View Avenue to the north, but should be very low because of the indirect connection to any functionally classified street. If the connection to Yellow Peak Avenue is made, about 10% of the development's traffic is likely to use this route to avoid traveling through the Ustick/Locust Grove to travel to the west. Most of the new traffic that is likely to travel through the Wanda's Meadow Subdivision to access Ustick Road would be from the Heritage Commons Subdivision. This route is a much more direct route for residents of that subdivision traveling to or from the west than what is available to them now.

If the connection to Yellow Peak Avenue is not made, the traffic volume on Park Crossing Avenue within the Heritage Commons Subdivision could exceed the 1,000 vehicles per day for local streets as specified in ACHD's development policies. The traffic volume predicted on Park Crossing Avenue by the Heritage Commons Traffic Impact Study conducted by Washington Group International is 867 vehicles per day. The connection to Yellow Peak draws traffic out of Heritage Commons Subdivision which counterbalances the additional traffic passing through Heritage Commons generated by Chalet Marseilles. Chalet Marseilles Subdivision 9 J-U-B ENGINEERS, Inc. Baseline Plus Site Traffic Site traffic was added to the baseline traffic to determine the capacity and level of service for the Ustick/Locust Grove intersection and the intersections at the subdivision access points for the build -out year of 2010. Level of service is a measure of average vehicular delay on the controlled approaches at an intersection. Analysis was conducted for AM and PM peak hour conditions. Tables 2, 3 and 4 show the peak -hour traffic volumes for the study intersections for the baseline plus sight conditions in 2010.

The westbound left turn operates at LOS F during the AM and PM peak hours without site traffic. The volume for this movement is approaching 300 vehicles during peak traffic hours. This is the point at which a dual left turn is considered for improving the capacity of a left -turn movement. There is space on Ustick Road to provide an additional left -turn lane, but because of the existing lane alignments, adding the lane may cause other operational issues. Installation of a southbound through -lane will improve the westbound left -turn movement LOS to E. The additional southbound lane reduces the time needed to serve southbound through traffic and makes this additional time available to serve the westbound left -turn lane.

ACHD's development policy calls for local street intersections to be offset by at least 125 feet. The purpose of this policy is to minimize conflicts between vehicles entering or exiting the side streets. There is ample distance between Ustick Road and Monet Street to provide for the offset without losing full access to Monet Street. As presently designed, the offset is about 50 feet between Monet and Summerheights. - There is virtually no offset between Monet and the church driveway.
