The study area was extended west of Interstate 15 (I-15) based on comments received from the public during prior local studies and from elected public officials during informal consultation before scoping for the Draper Transit Corridor Project began. The study area is located primarily in the cities of Sandy and Draper and includes parts of White City, South Jordan, and Bluffdale. The project study area is shown in Figure 1-2, Project Study Area, at the end of this chapter. This chapter explains the purpose of and need for the Draper Transit Corridor Project. The chapter describes the background of the project, including the results of related studies conducted to date; the transportation problems in the study area; and the regional and local transportation needs that led UTA and FTA to identify the Draper Transit Corridor Project as a potential solution to the existing Draft Environmental Impact Statement Chapter 1: Purpose and Need | 1-1 Draper Transit Corridor Project transportation problems. The chapter also identifies the local and regional goals and objectives that will be used to evaluate project alternatives. 1.2 Summary of Project Purpose and Need 1.2.1 Purpose of the Project The purpose of the Draper Transit Corridor Project is to provide high-quality, high-capacity rapid transit service in the highly congested north-south travel corridor between Draper and downtown Salt Lake City as specified in the Wasatch Front Regional Council’s (WFRC) Wasatch Front Regional Transportation Plan: 2007–2030 (2030 RTP) (WFRC 2007a). The proposed project is intended to extend fixed-guideway public transportation service and benefits in the study corridor by providing faster, more-reliable transit services than what can be achieved by operating buses in mixed-flow traffic. The proposed project would provide more-reliable mobility for transit-dependent people (such as people of limited income, students, and retirees), encourage more pedestrian access to transit and less reliance on park-and-ride access at the existing end-of-the-line station, better serve reverse-peak travel movements for employment and educational access, serve rapidly developing areas, and decrease travel times to key urban area destinations. 1.2.2 Need for the Project The Draper Transit Corridor Project is needed because the travel What is travel demand? demands of residents and commuters in the study area in 2030 are Travel demand is the expected number expected to be greater than the capacity of the existing transportation of transportation trips in an area.

Transit Corridor study area is changing land-use patterns, including the development of new activity centers and other attractions such as major employers and shopping centers. The need for the project results from the following factors: • Increasing vehicle congestion. Past and projected increases in traffic congestion in the Draper Transit Corridor study area are due to increases in regional and corridor population and employment. Between 2005 and 2030, the amount of time that 1-2 | Chapter 1: Purpose and Need Draft Environmental Impact Statement Draper Transit Corridor Project drivers spend in traffic in the Sandy and Draper areas is projected to increase by 115%, or more than double. As people travel more miles within an area, traffic slows down and is more likely to operate under stop-and-go conditions. • Lack of reliable travel times.

For people who live or work in the study area but do not live close enough to walk to an existing TRAX station, the travel choices are limited to automobiles, local bus service, or travel by auto to a TRAX light-rail station. • Need for operational efficiency. UTA’s increasingly scarce operating resources require more-efficient transit service. Light- rail trains can carry more passengers per unit of labor cost than buses can, which improves the efficiency of the transit system. • Need to support local plans for transit-oriented development. Sandy and Draper Cities have identified land-use and development goals and objectives for residential, commercial, retail, and industrial development that endorse extending rail transit service to help accommodate forecasted regional population and employment growth, alleviate highway congestion during peak periods, and limit the expansion of local arterial roads. • Limited highway system capacity. There are limited opportunities for expanding highways and major roads east of I-15. Travelers on both I-15 and the arterial streets through Draft Environmental Impact Statement Chapter 1: Purpose and Need | 1-3 Draper Transit Corridor Project Sandy and Draper are already experiencing more congestion and longer delays during peak travel times. • Increasing adverse health effects due to air pollution. The amount of time that vehicles spend in traffic (vehicle-hours per square mile) in the Draper Transit Corridor study area is projected to increase, and this will lead to greater air pollution emissions per square mile. This more-intense exposure to air pollution can have negative health effects, even if overall air pollution levels are falling. 1.3 Needs Assessment The following sections provide data that support the need for the Draper Transit Corridor Project. 1.3.1 Population and Employment Growth in the Study Area The study area is located in the steadily growing southeastern part of Salt Lake County. The study area has experienced rapid growth in the past decade and is expected to continue this growth through 2030. As indicated in WFRC’s 2007–2030 Regional Transportation Plan, the population along the entire Wasatch Front is projected to increase by 42% between now and 2030 (from 955,541 to 1,357,637). 1.3.1.1 Population Growth Table 1.3-1 presents the forecasted population for the cities of Sandy and Draper. Sandy has a more established housing base, and population is projected
