67 Flats & Juniper Square Traffic Impact Study – Category I Prepared for: Dominium 2828 N Central Avenue, Suite 1100B Phoenix, AZ 85004 Prepared by: Project Number: 21.5281 September 7, 2022 Lōkahi, LLC 10555 N. 114th Street, Suite 105 Scottsdale, AZ 85259 09/07/22 Alan Heathcoat, P.E. Principal Engineer Glendale Transportation 09/09/2022 12:57:18 PM APPROVED 1 67 Flats & Juniper Square Traffic Impact Study – Category I 1. Introduction and Executive Summary 1.1. Purpose of Report and Study Objectives Lōkahi, LLC (Lōkahi) was retained by Dominium to complete a Traffic Impact Study for the proposed 67 Flats (multi-family) and Juniper Square (senior living) developments. The proposed multi-family and senior family residential developments will be located on the northwest corner of 67th Avenue and Maryland Avenue in Glendale, Arizona. The proposed development will include the following two (2) land uses: 67 Flats Multi-Family 384 dwelling units 12 one-bedroom units 204 two-bedroom units 168 three-bedroom Juniper Square Senior Living 221 dwelling units 66 one-bedroom units 131 two-bedroom units 24 three-bedroom See Figure 2 and Appendix A for the proposed site plan. The objective of this Traffic Impact Study is to analyze the traffic related impacts of the proposed development to the adjacent roadway network. 1.2. Executive Summary This report presents the analyses and results of a traffic study prepared for the proposed 67 Flats and Juniper Square developments. The proposed development is anticipated to open in the year 2024. 2 67 Flats & Juniper Square Traffic Impact Study – Category I This Traffic Impact Study includes: • Level of service analysis for the existing conditions weekday AM and PM peak hours • Trip Generation for the proposed development • Level of service analysis for the build out year (2024) weekday AM and PM peak hours • Level of service analysis for the build out year + 3-year (2027) weekday AM and PM peak hours • Turn lane warrant analysis The following intersections are included in this study: • 69th Avenue and Ocotillo Road (1) • 67th Avenue and Ocotillo Road (2) • 67th Avenue and Driveway A (3) • 67th Avenue and Driveway B (4) • 69th Avenue and Maryland Avenue (5) • Maryland Avenue and Driveway C (6) • Maryland Avenue and Driveway D (7) • 67th Avenue and Maryland Avenue (8) Existing Conditions The capacity and level of service for the study area intersection were evaluated for the existing conditions. All study area intersections operate with movements at a level of service (LOS) D or better with the exception of the following: 67th Avenue and Ocotillo Road (2) • EB left AM and PM peak hours operates at LOS F • EB shared through-right PM peak hour operates at LOS E • WB left AM and PM peak hours operates at LOS F Trip Generation The trip generation for the proposed 67 Flats and Juniper Square developments was calculated utilizing the Institute of Transportation Engineers (ITE) publication entitled Trip Generation, 11th Edition. ITE Land Use 220 – Multifamily Housing (Low-Rise) and 252 Senior Adult Housing – Attached were used to calculate the trips generated by the proposed development. 3 67 Flats & Juniper Square Traffic Impact Study – Category I Trip Generation – Proposed Development The proposed 67 Flats and Juniper Square developments is anticipated to generate a total of 3,201 weekday trips, with 185 AM peak hour trips and 241 PM peak hour trips. Future Conditions Year 2024 (build out) and Year 2027 (built out + 3 years) analyses were completed with the build out of the proposed 67 Flats and Juniper Square developments. Utilizing Maricopa Associations of Governments (MAG) socioeconomic projections, existing traffic volumes grown by an annual growth rate of 2.0% to determine the year 2024 and 2027 traffic volumes. Year 2024 Capacity analysis was completed for both the AM and PM peak hours for the year 2024, with the build out of the proposed 67 Flats and Juniper Square developments. All movements at the study intersections operate at a LOS D or better, with the exception of: 67th Avenue and Ocotillo Road (2) • EB left AM and PM peak hours operates at LOS F • EB shared through-right PM peak hour operates at LOS F • WB left AM and PM peak hours operates at LOS F • WB shared through-right PM peak hour operates at LOS F 67th Avenue and Driveway B (4) • EB left AM and PM peak hours operates at LOS F • WB shared left-through-right PM peak hour operates at LOS E Delays are typical during peak hours for minor-to-major turning movements, especially at stop- controlled intersections. Drivers familiar with the area often choose to use alternative routes during peak hours or drive at different times to avoid potential delay. The existing upstream signals will also help to provide gaps in traffic to allow for turns at these stop-controlled intersection. Therefore, improvements to mitigate LOS E and F at the above intersections are not recommended as part of this study.

The results of the year 2027 build capacity analysis reveal that the study intersections operate with a level of service (LOS) D or better, or are maintained at the year 2024 build level of service. Turn Lane Warrant Analysis Based on the MCDOT right turn lane warrant criteria, a right turn lane is warranted at Driveway A, and not warranted at Driveway B. Additionally, a southbound right turn deceleration lane is not warranted at the intersection of 67th Avenue and Maryland Avenue (8). Recommendations • 67th Avenue and Driveway A (3) Buildout of a full access driveway and a southbound right turn deceleration lane with 150 feet of storage and 100 feet of straight-line taper. • 67th Avenue and Driveway B (4) Buildout of a full access driveway • Maryland Avenue and Driveway C (6) Buildout of a full access driveway • Maryland Avenue and Driveway D (7) Buildout of a full access driveway As with any new development and potential change in traffic patterns, the following is recommended: • Monitor and Adjust Signal Timing Monitor traffic patterns in the area and if necessary, adjust nearby signal timing 5 67 Flats & Juniper Square Traffic Impact Study – Category I 2. Proposed Development The study area is located in the City of Glendale, Arizona. The site is located on the northwest corner of 67th Avenue and Maryland Avenue.
