A caveat about the information presented in Table 4: the data about
<br />residential development is both complex and somewhat scant. Each
<br />development may have idiosyncrasies, such as factors that limit
<br />development density or footprint (such as a stream). Moreover, it is
<br />typical to see cycles in building: for example, a lot of single-family units
<br />get built so then a lot of multi -family follows. For example, the achieved
<br />mix over the 2001 to 2008 period (69% single-family housing types and
<br />31% attached housing types) was the result of an unusual housing market
<br />bubble. Similarly, the mix of housing developed over the 2009 to 2012
<br />period (39% single-family housing types and 61% attached housing types)
<br />was the result of a historic downturn in the housing market. It seems
<br />unlikely that either will be repeated over the 20 -year period. ECO
<br />recommends looking at building trends broadly and on average over a
<br />several -year period (e.g., for the entire 2001 to 2012 period), rather than on
<br />a shorter -term basis.
<br />Table 5 shows changes in Eugene's housing mix from 1990 to 2011, based
<br />on U.S. Census data. Between 1990 and 2011, Eugene increased its housing
<br />stock by 47%, adding 22,361 dwelling units. Between 1990 and 2000, the
<br />mix of housing did not change substantially. In 2011, the share of single-
<br />family detached units (e.g., single-family houses and manufactured
<br />homes) was 56%, down from 59% in 2000.
<br />Over half of new dwellings built in Eugene over the 1990 to 2011 period
<br />were attached housing types (e.g., single-family attached and structures
<br />with two or more units), accounting for more than 11,400 new units built.
<br />The share of attached structures increased slightly, accounting for 40% of
<br />dwellings in 1990 and 46% of dwellings in 2011.

<br />homes in parks or on single lots. Includes all dwellings within city limits.
