Below is the Draft Testimony of Mary Vogel,CNU-A, principal of PlanGreen, regarding the Lacamas Northshore proposal that Carolyn Foster covered in her blog earlier in August.

I know that you are concerned with the city’s economy—in the long term, not just today.  I suspect that you believe that the proposed master plan will help the city’s economy.  But I want you to consider some future trends before you make up your minds.

Maureen McAvey, Senior Resident Fellow for the Urban Land Institute (ULI) in Washington, DC  was in Portland last year to discuss the ULI publication “What’s Next? Real Estate in the New Economy“.  The event notice read: A paradigm shift is unfolding over the course of this decade, driven by an extraordinary convergence of demographic, financial, technological and environmental trends. Taken together, these trends will dramatically change development through 2020. My notes indicate that McAvey said:

• More single-family homes are being occupied by renters, changing the feel and politics of suburban communities
• Seventy-five percent of households in the Portland area do not have children under 18
• 47 percent are non-families
• Twenty-somethings on tight budgets prefer places to congregate with friends — in parks, bars, restaurant clusters and building common areas — and can tolerate smaller living spaces.

Arthur C. Nelson, one of the nation’s most prescient housing market researchers, says declining homeownership, tighter lending standards, a sell-off of single-family houses by the nation’s fastest growing demographic — senior citizens—and even rising household sizes due to more multigenerational living will have an impact on the market you may be trying to attract with the single family home portion of the plan.

Nelson, professor of city and regional planning at the University of Utah, reports that the US faces a massive oversupply of large-lot single family houses and an undersupply of multifamily units. By 2020, Nelson sees 1.5 to 2 million homes from seniors coming on the market, and between 2020 and 2030, there will be a national net surplus of 4 million homes that they cannot sell. And Nelson believes those are conservative figures for what has been dubbed “The Great Senior Sell-Off.”

The 2009 American Housing Survey (AHS) found that 28 percent of houses are attached, 29 percent are detached on small lots, and 43 percent are detached on large lots. Three studies — by National Association of Realtors, the Robert Charles Lesser & Co. (RCLCo), and Nelson — all found a nearly identical, imbalance in US housing supply and demand.  Only 24 to 25 percent of Americans would prefer to live in large-lot single-family houses (see graph “Housing preference versus supply”).

Consequently, there’s an oversupply of approximately 28 million units in what developer, professor and author Christopher Lineberger calls “the drivable suburbs.”  Attached housing and small-lot housing, on the other hand, are undersupplied — by about 12 million and 13.5 million units, respectively.

This imbalance is likely to grow in the years to come, reports Nelson. The generation that is currently moving into the housing market — Millennials — is the most urban-oriented cohort since World War II.  Melina Druggall with RCLCo reported at a National Association of Home Builders conference in January 2011 that 81 percent of Gen Y renters want to live in an urban setting.  (Wall Street Journal reported that number as 88% at that time and they were quoted in numerous sources such as Better Cities & Towns and Grist).

Ninety percent of the increase in the demand for new housing will be households without children, and 47 percent will be senior citizens (the latter resulting from the rising tide of Baby Boomers who started turning 65 last year). Both of these demographic groups—the Millennials and the Boomers—lean toward multifamily and away from large-lot SFH.

Referring to a recent National Association of Realtors (NAR) finding on percentage of households that prefer to live downtown or in mixed-use city or suburban neighborhoods, Nelson says “Back in ‘70s or ‘80s, people wanted drivable suburbs. Now 70 percent want to walk to discernable destinations, from transit to grocery stores. This wasn’t the case until recently.”  Nelson believes the most popular locations will be mixed-use, walkable, transit-friendly neighborhoods.

This Lacamas Northshore master plan is being portrayed as both walkable and mixed-use, but the concept plan I’ve seen so far indicates to me that it is not.  The zoning proposal shows a segregation of uses. Business parks, by their very nature, are drive-to!  The single-family and the multi-family seem quite segregated from each other and all are segregated from the shopping area.

As far as economic development is concerned, there is increasing evidence that the kind of high tech, light industrial firms that you hope to attract are choosing to locate near where their employees want to live.  Consider the choice of Amazon to locate adjacent to downtown Seattle and Adobe Systems to locate in downtown San Jose.

I hope you will take into account the “extraordinary convergence of demographic, financial, technological and environmental trends” that ULI talks about before making your decision on this zoning change and the future development that it presages.  I agree that a master plan with changed zoning is what is now most desirable for this area–but NOT the kind of segregation of uses we see in this plan. I urge you to delay approval of a zoning change–until you can get it right!
