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)
