CC - Transportation Memo K I TT E LS O N 101 S CAPITOL BOULEVARD,SUITE 301 BOISE,ID Ic & ASSOCIATES P 208.3 826832 F 208.338.2685 MEMORANDUM Date: May 13, 2022 Project#:27301 To: Paige Bankhead, El Ada County Highway District From: Sonia Hennum Daleiden, PE PTOE & Katie Popp cc: Mike Maffia, Perserve West Capital Project: Eagle Road/Ustick Road Multifamily Residential Development Subject: Transportation Impact Study Scope of Work and Assumptions This memorandum documents the requested transportation information for the proposed Multifamily Residential Development located on Ustick Road between Centrepoint Way and Cajun Lane in Meridian, Idaho. The information presented in this memorandum was developed based on conversations with Preserve West Capital (the applicant) and the Idaho Transportation Department (ITD) and the Ada County Highway District (ACHD). Figure 1 shows the proposed site plan and Figure 2 shows the site vicinity of the development. The site in question was previously approved with a different development in 2018/2019 however that development has not been constructed. Given that the site had a previous approval, Kittelson has coordinated with ACHD and ITD on what transportation information is required for the proposed new use on the site. Based on these conversations, ACHD requested the following items be addressed in this memorandum: ■ Project Description ■ Trip Generation Comparison ■ Parking Analysis ■ Cut-Through Trip Evaluation FILENAME.,H.127127301 -EAGLE USTICKMULTIFAMILYRESIDENTIAL IREPORTISCOPING MEM0127301-EAGLE USTICK MUL 77FAMIL Y RESIDENTIAL TRANSPORTATION MEMO V2.DOCX Eagle/Ustick Road Multifamily Residential Development Transportation Memo Project#.27301 May 13,2022 Page 2 PROJECT DESCRIPTION The previously approved site consisted of an 89,000 square foot VillaSport health and fitness facility. The site proposed three access points: one at Centrepoint Way and one at E Picard Street,with a right- in right-out access on Ustick Road. Since the 2018 study,the right-in right-out access to Ustick Road has been constructed and named Cajun Lane. The proposed Eagle Road/ Ustick Road Multifamily Residential Development is located on approximately 10 acres of land south of Ustick Road between Centrepoint Way and Cajun Lane in Meridian, ID.To replace the previously approved VillaSport,the development proposes 259 multifamily residential dwelling units and is classified as a mid-rise residential development per the ITE Trip Generation Manual, 111" Edition. Future commercial and retail development is also proposed on the site between Cajun Lane and Eagle Road (SH 55) but is not included as part of this study. The site is currently zoned C-G (commercial general), which allows for multi-family residential development with a Conditional Use Permit ("CUP"). Buildout of the proposed multifamily residential development is expected by 2024. The Multifamily Residential Development will provide four accesses upon buildout: two access points on Centrepoint Way, which intersects with Ustick Road, and two access points on Cajun Lane, which intersects with Ustick Road at a right-in/right-out access (see Figure 2).The new site proposal accesses differ from the previous proposal slightly with the development of Cajun Lane but are otherwise in similar locations as the 2018 study.

The proposed Eagle Road/ Ustick Road Multifamily Residential Development will consist of 259 total dwelling units, which meets ITE specifications for the 221 — Multifamily Housing (Mid-Rise) land use code. The previously approved development application proposed an 89,000 square foot VillaSport health and fitness facility. Table 1 shows a comparison of the trip generation assumed in the 2018 VillaSport transportation impact study to trip generation calculations for the proposed multi-family residential development. A description of the trip generation rate calculations and assumptions can be found in the 2018 TIS (Reference 2). Table 1.Trip Generation Comparison ITE D.

As can be seen from the table, the proposed multifamily residential development is expected to generate fewer trips than that of the existing approved VillaSport development. The multifamily development is projected to generate 1,651 fewer daily trip ends, 80 fewer weekday AM peak hour trip ends, and 166 fewer weekday PM peak hour trip ends compared to the currently approved use for the site.

Boise,Idaho Eagle/Ustick Road Multifamily Residential Development Transportation Memo Project#.27301 May 13,2022 Page 7 CUT-THROUGH TRIP ANALYSIS An existing single-family development located south of the proposed site is connected to the proposed development at Centrepoint Way and Cajun Lane.That residential development is boarded to the south and west by fencing and does not connect to the roadway network except at the same locations as this proposed multifamily development. Because of this, unless going to specific visit one of the residences in the south development, there would be no reason for traffic from the proposed multifamily residential development to use the internal roadways to the south. The only connections that the multifamily residential development will likely use are highlighted in Figure 4. 29 bon 1 F � w k Y... 1 M 1 I e 5 S i .4 =:.fit. �-,�• Figure 4: Cut Through Analysis Kittelson&Associates,Inc. Boise,Idaho Eagle/Ustick Road Multifamily Residential Development Transportation Memo Project#.27301 May 13,2022 Page 8 A COMPASS model and existing traffic volumes were used to develop a trip distribution pattern (shown in Figure 5) and resulting site trip assignment (shown in Figure 6) to further assess the actual number of site trip potential on the segments shown in Figure 4.The most likely traffic on the segments shown on Figure 4 will come from people traveling outbound south on Eagle Road, which provides access to 1-84. Because the access is right-in right-out only, an inbound cut through along these segments is only possible from southbound traffic on Eagle Road. As can be seen in Figure 6, the proposed site contributes 30 outbound trips in the AM peak and 15 outbound trips in the PM peak at the Seville Road and Eagle Road access. Inbound traffic at the same access contributes 3 trips in the AM peak and 9 trips in the PM peak. Given the small number of additional trips from the proposed site that utilize the Seville Lane and Eagle Road access for inbound and outbound traffic, we conclude that cut through traffic in the existing residential development segments (E Seville Lane, N Cajun Lane, E Picard Lane,and E Picard Street) will not be a significant concern. We trust this memorandum provides the information requested for ACHD's review of the proposed multifamily residential development.
