Recommendations for Baseline Assumptions ECONorthwest April 2009 Page 12 ? Data source: The assumption about vacancy rate is based on a point estimate from the U.S. Census, American Community Survey. Housing mix Housing mix is the mixture of housing types (e.g., single-family detached or apartments) within a city. State law requires a determination of the future housing mix in the community and allows that determination to be based on different periods: (1) the mix of housing built in the past five years or since the most recent periodic review, whichever time period is greater, (2) a shorter time period if the data will provide more accurate and reliable information, or (3) a longer time period if the data will provide more accurate and reliable information (ORS 197.296). This memorandum presents housing mix data for two periods (1) housing mix over the 2001 to 2008 period and (2) housing mix over the 1990 to 2007 period. Table 2 shows the housing mix for residential development over the 2001 to 2008 period. We selected this time period over the 1999 to 2008 period because it shows housing mix that occurred since the City’s revised zoning ordinance went into effect in 2001. About 64% of housing developed was single-family detached, 10% was single- family attached, 5% was manufactured, 3% was duplex, and the remaining 18% were structures with 3 or more units. The share of single-family housing varied from a high of 84% in 2001 to a low of 43% in 2007. Table 2.

The share of single-family detached housing was relatively stable over the seventeen-year period, accounting for about 55% of housing stock in Eugene. A caveat about the information presented in Table 3: the data about residential development is both complex and somewhat scant. Each development may have
