Eugene needed housing density and mix ECONorthwest Page AB:D PPENDIX ATA AND ADDITIONAL TABLES This appendix presents additional data and tables, which supplements the discussion about variations on Eugene’s housing density and mix in this memorandum. This appendix presents historical housing density and mix data that support the assumptions about density and mix used in ECLA. Table B-1shows average net residential density by structure type for the 2001 to 2008 period. Table C-6 shows that 4,727 tax lots had residential development during the 2001 to 2008 period, adding 6,532 dwelling units. Some tax lots had pre-existing new multifamily dwelling units. The average density for all residential development over the 2001 to 2008 period was 7.2 dwellings per net acre. 13 Table B-1.

Table B-2 shows changes in Eugene’s housing mix from 1990 to 2007. Between 1990 and 2007, the City’s mix of housing did not change substantially. The share of single-family detached units (e.g., single-family houses and manufactured homes) remained at 61% over the 17 year period. The share of attached structures did not change substantially, accounting for 40% of dwellings in 1990 and 39% of dwellings in 2007. The density of 7.2 units per net acre accounts for all development on the 4,727 tax lots shown in Table B-1. While 13 the density analysis focuses on development that occurred between 2001 and 2008, we would underestimate density on these tax lots if we did not account for multifamily dwellings built in phased development prior to 2001. OAR 660-024-0010(6) uses the following definition of net buildable acre. “Net Buildable Acre” consists of 43,560 square feet of residentially designated buildable land after excluding future rights-of-way for streets and roads. While the administrative rule does not include a definition of a gross buildable acre, using the definition above, a gross buildable acre will include areas used for rights-of-way for streets and roads. Areas used for rights-of-way are considered unbuildable. PC AIS, p21
