Below is a summary of the submitted information. . The site will generate 16,400 new vehicle trips per day. Of these 700 will occur during the AM peak hour and 1,241 will occur during the PM peak hour. . The site will access the transportation system via Chinden Boulevard (Us 20/26) at two major locations: Black Cat and a proposed Tree Farm Way intersection across from the Bainbridge Subdivision. . The proposed access points comply with ITD access policy for Chinden Blvd. (US 20/26). The intersections are at Y2 mile spacing. . The project will be phased. Limits of the phasing have not been determined, but the east end of the site will be developed first. This means the Tree Farm Way intersection will serve as the initial access to the site and the Black Cat intersection will be developed as market conditions permit. . The intersection of Black Cat Road and Chinden Blvd. will operate at LOS E under 2010 background traffic conditions. Under total traffic conditions, the intersection will fail to operate as a stop controlled intersection. The intersection will require the installation of a traffic signal and lane widening to operate at an acceptable level of service. . The intersection of Tree Farm Way and Chinden Blvd. will operate at LOS C under 2010 background traffic conditions. Under total traffic conditions, the intersection will operate at LOS F. Based on the assignment assumptions, a signal will be required to achieve an acceptable level of service. . The intersection ofTen Mile Road and Chinden Blvd. will operate at LOS F under 2010 background traffic conditions. This assumes that improvements are made to the intersection as recommended in previous traffic impact studies. Without these improvements, the delay is significantly higher. If site traffic is added the delay increases. . The US 20/26 corridor is currently the subject of a corridor study to determine what improvements are required to accommodate expected regional travel demands. The results of this study will not be available for several months. A review of COMPASS demographics indicates this development is in conformance with the assumptions of the study. '" --,'. . This development provides a local stub road for access to Basco Lane north of the project. Basco Lane will connect to an internal residential collector road. Staff Comments: . The TIS could be underestimating the amount of traffic going east of the site. The TIS has 50% of the traffic going east. Currently 65% of the traffic is from the east. . The TIS indicates the need for traffic signals at the site access intersections with Chinden Boulevard. The applicant will be responsible for the installation costs of those signals. . When the District reviews the preliminary plat, the need for stub streets to the surrounding properties will be closely examined. District staff anticipates that there may be a need for three stub streets to the north, potentially one to the east, and potentially one or two to the west. There is approximately 1 ,OOO-acres of undeveloped property to the north of this site, below the rim. It will be critical that this site provides adequate connectivity opportunities to the undeveloped property. . The applicant is proposing to construct Black Cat Road through the site where it does not exist today. District staff anticipates that this roadway, at a minimum, will need to be a collector street. It may be considered for a 3-lane minor arterial through this site. . It appears that the applicant is proposing an internal street network of residential collectors and local streets. Upon receiving a preliminary plat application, the District will review the applicant's proposal in depth and place conditions on the location and design of the proposed roadways. These comments are provided to help assist the decision of the Meridian City Council in the annexation and rezone request. The District will provide detailed comments and conditions upon submittal of a preliminary plat application. ") ~) ) Legend ~ lliJ""".., ',',", ' ','",,' ,L,,"::':.'.,..
