The Phoenix metropolitan area’s “favored quarter” for employment in 1995 – the metro area’s highest employment densities outside the primary core – extended from Chaparral Road in Scottsdale to Baseline Road in Tempe. Downtown and South Scottsdale’s success can be traced to being adjacent to the favored residential quarter that extends from the area around the Phoenix Mountains through north Scottsdale. In the 1990s, the favored employment quarter has been extending north in Scottsdale through the favored residential quarter. The presence of Arizona State University, proximity to Sky Harbor Airport, and access to the region’s first two freeways contributed to the portion of Tempe north of Baseline Road becoming the largest employment center outside of the primary core in Phoenix. Employment also was above average south of Baseline Road, extending into the secondary favored residential quarter of South Tempe and Ahwatukee – Foothills. Considering residential and economic factors, the Phoenix metro area’s favored quarter stretches from north of Squaw Peak in northeast Phoenix through Paradise Valley, Scottsdale, and Tempe to south of South Mountain in southeast Phoenix.
