10 Id. The Court stated:
With particular reference to apartment houses [namely residential neighborhoods made up of single family homes on their own lots], it is pointed out that the development of detached house sections is greatly retarded by the coming of apartment houses, which has sometimes resulted in destroying the entire section for private house purposes; that in such sections very often the apartment house is a mere parasite, constructed in order to take advantage of the open spaces and attractive surroundings created by the residential character of the district. Moreover, the coming of one apartment house is followed by others . . . .

We, the people of the Portland area metropolitan service district, in order to establish an elected, visible and accountable regional government that is responsive to the citizens of the region and works cooperatively with our local governments; that undertakes, as its most important service, planning and policy making to preserve and enhance the quality of life and the environment for ourselves and future generations; . . . do ordain this charter for the Portland area metropolitan service district, to be known as Metro.

Const. art XI, � 14.

The Metro Council shall adopt a “fair share” strategy for meeting the housing needs of the urban population in cities and counties based on a subregional analysis that provides for:
� a diverse range of housing types available within cities and counties inside the UGB;
� specific goals for low- and moderate-income and market rate housing to ensure that sufficient and affordable housing is available to households of all income levels that live or have a member working in each jurisdiction;
� housing densities and costs supportive of adopted public policy for the development of the regional transportation system and designated centers and corridors;

These mandated changes demand adherence to certain regionwide affordable housing policies, including: (1) minimum densities shall be required in all residential zones; (2) at least one accessory unit shall be allowed within any detached single family dwelling; (3) in order to implement 2040 Growth concept, densities shall be increased in rail station areas; and (4) a performance standard requiring a density bonus shall be adopted. Id. � 1.3.4.1–.4. In addition, these changes demand that an Affordable Housing Functional Plan be developed containing requirements that cities and counties adopt numerical “fair share” targets.

139 Portland, supra note 134, at 2. The report on the Seattle area unfavorably contrasted the low-density development in greater Seattle with that in the Portland metro region: “But growth does not have to mean sprawl. If greater Seattle increased the average density of its developed areas to that of greater Portland’s (excluding Clark County, Washington), suburban development would cover only a fifth as much land—saving about 135,000 acres.” Seattle-Tacoma, supra note 136, at 2. The report on Vancouver, British Columbia showed a pattern of growth far more compact than that of either Seattle or the Oregon part of Portland. Vancouver, supra note 137, at 2.

See generally Population Research Ctr., Portland State University Components of Population Change for Oregon’s Counties: April 1, 1990 to April 1, 2000 (2000) (citing U.S. Census data for Clackamas, Multnomah, and Washington Counties, within which TriMet provides transit service), http://www.upa.pdx.edu/CPRC/90–00-census.PDF (last visited Feb. 7, 2003).
141 This figure was calculated by summing the total vehicle miles traveled (VMT) on state highways in Clackamas, Multnomah, and Washington counties, which encompass the TriMet service area. Or. Dep’t of Transp., Oregon VMT (Oregon Vehicle Miles of Travel for State Owned Highways) (2002), http://www.odot.state.or.us/tdb/traffic_ monitoring/vmt.htm (last visited Feb. 7, 2003). TriMet’s service boundary encompasses about 600 square miles compared with the 3027 square miles in the three counties. See TriMet, Facts About TriMet 1 (2002), http://www.trimet.org/news/pdf/factsheet02. pdf (last visited Feb. 7, 2003). But because the vast majority of the regional population—and driving—falls within the urban area served by TriMet service, it is unlikely the geographic mismatch makes a significant difference in regional VMT trends.
142 Charles Schmidt observes:
[Clean Air Act] violations in Portland have dropped from an average of 100 per year in the 1970s to none since 1987. . . .
Says William Schroer, a project manager with Apogee Research in St. Paul, Minnesota, “Portland has held per-capita VMT steady over the past three years, an impressive accomplishment in an economy that is growing at twice the national average. Among other things, it means that in Portland, increases in driving are not currently eating into the decreased emissions benefits that technology has brought.
