action was acknowledged by the Oregon Department of Land Conservation and Development <br />pursuant to ORS 197.625(1)(a). <br />➢ Efficiency Gained: 645 dwelling units of Low Density Residential. The reduction to the <br />Medium Density Residential land capacity is reflected in Table 5 below. <br />2. Permit fee Reductions for Secondary Dwelling Units (Low Densitv Residential <br />This measure provides efficiencies on land classified as developed, as well as vacant and partially <br />vacant land. SDUs (a.k.a. "granny flats" or "accessory dwellings") are additional dwellings that <br />are attached to or detached from the primary dwelling but located on the same lot, on property <br />zoned R-1 Low Density Residential. <br />Applicability: Increase the frequency at which SDUs occur in Low Density Residential areas by <br />restructuring permitting fees. <br />Assumptions: SDUS are already permitted in Low Density Residential zones. It is assumed that <br />decreasing the systems development charges for SDUs could increase production of SDUs by <br />some amount. This assumption is, in part, based on the fact that Eugene does not have enough <br />housing that is affordable to lower income households, suggesting that there would be demand <br />for SDUs as smaller housing types in existing developed areas that could be more affordable. <br />Over the 2001-2012 period, Eugene averaged about 8.4 SDUs per year.' A reasonable <br />assumption is that SDU production would increase by 50%. <br />Analysis: With an average of an additional four SDUs produced per year, this measure would <br />result in about 84 additional SDUs produced over the 20 year period. Estimated savings of about <br />21 acres. <br />Table 2.

These SDU restrictions <br />were related to interim protection measures for areas around the University of Oregon, increasing the minimum lot <br />size for an SDU to 6,100 square feet, and adding restrictions on flag lots. Those 2001-2012 SDUs that might not have <br />met these new standards were deducted from the total so that the forecast does not assume that SDUs on those lots <br />covered by the interim protection measures would occur in the future. <br />' This accounts for the decrease in SDUs on an annual basis due to interim protection measures adopted after 2012 <br />for areas around the University of Oregon. <br />Residential Land Supply Study I Final Part IV — Page 6 <br />
