Scenario S: Preferred Alternative
Scenario S:Creating Mixed-use Centers Around Major Transportation Areas Is The Primary Driver Of Improved Transportation Performance
• Plan a range of mixed use centers around transit– A few regional
centers– Many neighborhood
centers– Close access to
centers throughout the Vistas

Scenario X: Basecase
Scenario X Land Use Parameters
• Half the housing units and jobs of Scenario A– 202,500 Housing Units
• 80% single family housing• Averaging about ~6 dwelling units per net acre (3-4 per gross), similar to
single family prevalent in the Gold Canyon and San Tan Valley areas– 150,000 Jobs
• Primarily strip commercial with some office • Retail and employment centers located at freeway and arterial
intersections• Small amount of multi-family located around interchanges and
employment centers• Less environmental sensitivity and open space
– More encroachment into washes– Development on slopes– Fewer parks, more golf courses
Scenario X Transportation Parameters
• No regional transit, limited local transit
• Freeways built as planned
• Highway 60 and 79 expanded to 6 lane expressways, but with surface intersections
• Extension of existing major arterials – Follow conventional arterial
pattern of one arterial per mile (use section lines)
