seeing. Examples include lots that have already been platted for single-family housing or smaller lots within existing single-family areas. The City Council directed staff to exempt sites less than 0.5 acre from the new density requirement. The buildable lands inventory was queried and identified 31 acres that are Medium Density Residential and less than 0.5 acres. As shown in Table 3, the additional capacity from the increased density is reduced to 566 dwellings when the new density is applied only to lots 0.5 acres or greater. This results in about 48 medium density dwellings (or 4.8 acres) remaining. Table 3.

In order to facilitate the increase in average density to 15.4, the R-2 zone must be amended. The minimum density would need to be 12.8 but because the Eugene Land Use Code Chapter 9 provides minimum and maximum densities based on whole numbers rather than fractions of numbers, the City proposes a minimum density of 13. This would address the small amount of remaining need (48 dwellings). Other considerations Although 15.4 dwellings per net acre is already within the allowable density of R-2 zoning (10-28 dwellings per net acre), the City considered whether the remaining land supply is too constrained to support this change and whether there are examples of R-2 subdivisions already meeting this density. Review of the MDR vacant and partially vacant land supply indicates that most of the supply (82%) is on land with less than 5% slope. The next highest slope category is 10-15% slope, at 13% of the supply. Therefore, the slopes of the MDR land in the buildable lands inventory do not initially appear to be a limiting factor for requiring single-family detached housing to be developed at a higher density. Review of R-2 zoned subdivision plats found that about half of the plats approved from 2001- 2014 would need to add a significant amount of additional units to meet the targeted net density for single-family detached development. The other plats either already meet the target net density, would need to increase the number of lots by less than 15%, or were part of a planned unit development which allows for more flexibility in meeting development standards. Timing: Amendments to the R-2 Medium Density Zoning Code are proposed with the adoption of this Residential Land Supply Study. Residential Land Supply Study I Final Part IV — Page 8
