  3. Austin Student Demographics • UT enrollment • 1960: 20,396 • 1975: 42,589 • 2008: 50,006 • 2005 Campus Area Housing • UT campus: 7K • West Campus: 12K • North Campus: 5K • Total= 35K • West Campus zoning • Many years of latent demand http://www.ci.austin.tx.us/demographics/

  6. Density Issues • Lower Urban Density (sprawl) • Imperative for car usage, higher daily vehicle miles traveled per capita • Decreased car gas mileage due to congestion • Public transportation is inefficient • Higher Infrastructure costs • Roads (asphalt) • Water conveyance (pumping and materials) • Single Family homes have poor energy efficiency compared to multi-family • Surface area, materials use , capital energy cost • Sprawl displaces farming, higher food transportation costs to the urban area
