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
