Transit-oriented development is another colossal failure. High-density mixtures of residential and commercial uses located along transit routes are supposed to encourage walking or transit riding rather than driving. A wonderful theory, but in practice few Americans will live without autos. This means developers won't build transit-oriented developments without subsidies.
Ten years after Portland's first light-rail line was built, the city was so disappointed about lack of development along the route that it offered 10 years of property tax waivers to anyone building near rail stations.
One major development along the light rail, Beaverton Round, received $9 million in infrastructure subsidies and tax waivers. But no one wanted to move in, so the developer faced foreclosure. The city was recently forced to put up another $3.4 million to keep the project alive.
Portland's other planning legend is its urban-growth boundary, outside which development is restricted. Drawn in 1979 to include enough vacant land for an estimated 20 years' worth of growth, planners promised to expand the boundary when more land was needed.
By 1990, most vacant land was developed and land prices were rising. But by then the boundary was sacred, and some people loudly opposed any expansion. Although planners added a small amount of land, they decided to accommodate most growth by rezoning existing neighborhoods and urban open spaces to higher densities.
To meet population targets, Portland and 23 suburbs are rezoning neighborhoods of single-family homes for apartments. In these areas, if a house burns down, the owner must replace it with an apartment. Cities are also rezoning golf courses, 10,000 acres of prime farm lands and other open spaces to high-density development. Low densities are forbidden in these zones.
Such zoning is producing high apartment vacancy rates, while single-family home prices have skyrocketed. In 1989, Portland was one of the most affordable U.S. housing markets; since 1996, it has been one of the five least affordable.
Residents say they want less, not more congestion, but planners claim ``congestion signals positive urban development'' and predict their plan will triple congestion. With congestion comes pollution: Planners admit their plan will increase smog by 10 percent.
Planners gained the power to do these things by promising to save Portland from becoming like Los Angeles, the U.S.'s most congested city. Los Angeles is also the nation's densest metropolitan area and the one with the fewest miles of freeways per capita.
After reviewing statistics for 50 major U.S. urban areas, Portland planners concluded Los Angeles ``displays an investment pattern we desire to replicate'' in Portland.
Of course, they didn't say so very loudly.
If your idea of a livable city is Los Angeles - unbearable congestion, air pollution, unaffordable housing and shortages of open space - then by all means use Portland as your model.
If instead you prefer a city with less congestion and pollution and more affordable housing and urban open space, you had better look elsewhere.
