Washington State Department of Transportation projections continue to outstrip actual traffic trends year after year. There are many reasons for this trend: high gas prices, economic uncertainties, demographic shifts, and (perhaps) an increase in people’s preferences for car-lite lifestyles. Regardless of the reasons, though, it may be time for transportation planners to begin adjusting their expectations. view graphic »

High prices are taking a bite out of northwesterners’ appetite for gasoline. Total gas consumption in 2011 in Oregon and Washington has fallen modestly since the 2002 peak—driven by declines in per capita driving and gains in vehicle efficiency. Measured per person, though, residents of the two states have reduced their use of motor fuel to its lowest levels since the early 1960s—back when three dimes would buy you a gallon of gas. And early trends suggest that per capita consumption in the two states may be headed for a drop of as much as 2 percent in 2012. read more »
Over the last two decades, Clark County has added thousands of new residents to its rural areas. The implementation of Washington’s Growth Management Act in the mid-1990s appeared to have little influence on growth. view graphic »
Rural sprawl slowed on both sides of the Columbia after 2000. Yet Clark County’s rural areas still saw substantial population growth over the decade, while Oregon’s rural areas did not. view graphic »
The greater metro Portland, Oregon, straddles two states, offering an intriguing natural experiment for gauging the effects of different growth management laws. The Oregon side operates under the nation’s oldest and most mature growth management system, while the Washington side is governed by a newer law. Over the last two decades, Clark County, Washington, accounted for the large majority of all rural and exurban housing and population growth in the greater Portland area. read more »
Permeable pavement is one of the most promising green solutions that can help reduce and clean up polluted stormwater runoff. Like conventional pavement, it can be made of asphalt or concrete that’s either poured in place or sold as pavers, and it can be
used in a variety of settings, including on parking lots, low-traffic roadways, driveways, and sidewalks. read more »
