David v. Goliath II: Blanchard v. Nelson on growth along the Snake River Plain
At the NewWest.net planning conference in June of this year, Professor Arthur (Chris) Nelson of the University of Utah raised some eyebrows when he outlined his predictions for the U.S. housing market over the coming decades, and his thoughts on what that meant for Idaho.
USC Professor Richard Green openly disagreed with Nelson’s projections as did BoDo developer Mark Rivers. The Calculated Risk blog also had some critiques, but nothing major.
Nelson’s analysis indicated that Idaho’s population would fill in along the Snake River Plain from it’s western edge in Ontario, OR, over to the eastern side of Idaho ending at Rexburg. For me it’s not how many people will move here, but where they will actually settle. Though Nelson believes growth will fill in along the I-84 corridor, evidence seems to contradict him indicating that growth will instead occur between the Wasatch Front, and move north to Rexburg - skipping the Boise Valley all together. There are good reasons for this.
Wealth is already leaving the Boise Valley for eastern Idaho and the Wasatch Front.
IRS data from 2006 and 2007 show positive migration to Ada County within Idaho. However, those migrating to Ada County from other parts of the state had average adjusted gross incomes of $33,337 annually, while those leaving Ada County for other parts of the state had annual incomes of $40,582. In total, residents worth $139 million moved to Ada County, and residents worth a total of $154 million moved out. That is a loss of $15 million in gross income for Ada County, to other parts of Idaho.
Additionally, in that same period, half of the top ten cities to which Boiseans moved were along the I-15 corridor with Provo, UT ranking first; Salt Lake City (2); Idaho Falls (5); Ogden, UT (7); and Pocatello (8). The more stable economic climate of eastern Idaho and Utah is but one reason why Boiseans are leaving.
There are strong sociocultural linkages between eastern Idaho and Utah.
It used to be said that Idaho had two capitals: Spokane, and Salt Lake City. Indeed, Coeur D’ Alene, ID is part of a two-state metropolitan statistical area (MSA) that includes Spokane and Coeur D’ Alene, and the Logan, UT MSA includes counties in southern Idaho. But physical proximity is not the only connection. The Church of Jesus Christ of Latter Day Saints exudes a strong cultural presence along the Wasatch Front and Eastern Idaho. With the presence of the new Temple in Rexburg and a growing BYU-Idaho campus there as well, the cultural linkages between eastern Idaho and Utah are only getting stronger.
Gaps in the transportation system separate the Boise Valley from eastern Idaho, and eastern Idaho from Utah. The gap between Utah and eastern Idaho, however, is shrinking more quickly.
Traffic patterns along Idaho’s highway system (seen below) show a consistent level of traffic between Ontario, OR and Heyburn, ID. Traffic drops off significantly, though, between Heyburn and American Falls. Traffic flows again pick up significantly between American Falls and Rexburg.
Lower traffic counts also show up on I-84 heading south out of Heyburn, and on I-15 heading south out of Pocatello, much like the reduced counts between Heyburn and American Falls. In this day and age of regional employment exchange will eastern Idaho ultimately align itself along I-84, or I-15?
If America’s foremost planners with the America2050 project have their way, the Pioneer rail line - which runs from Seattle to Chicago by way of Boise and Salt Lake City - will one day run again. But that line also contains another important spur: the link from Salt Lake City to Pocatello. As gas prices rise, airlines will offer fewer flights meaning Boise will inevitably end up with less air service in favor of airlines servicing larger airports such as Salt Lake and Denver. The rail link between Salt Lake and Pocatello, which also mirrors the west coast’s chief north-south land route between Mexico and Canada (CANAMEX) will exert strong pressure on the region to further develop in a north-south manner, and not throughout the Snake River Plain.
With white-collar job growth flat or shrinking in the Boise Valley and the economy in eastern Idaho more stable, strong sociocultural linkages between eastern Idaho and Utah, and a developing transportation network between eastern Idaho and Utah, evidence seems to suggest that the north-south corridor along I-15, rather than the east-west corridor along I-84 seems better poised for long-term economic and population growth. Alas, only time will tell.
