Findings Addressing ORS 197.312(5) September 3, 2019 10 <br /> <br /> <br />limit traffic on the city’s alleys, many of which are unimproved, and to address livability concerns <br />associated with overcrowding. <br /> <br /> <br />Minimum Lot Size <br /> <br />9.2751 Special Development Standards for Table 9.2750. <br /> <br />(17) Accessory Dwellings. <br />(a) General Standards for Attached Accessory Dwellings. Except as <br />provided in subsection (c) below, accessory dwellings that are within the <br />same building as the primary dwelling shall comply with all of the <br />following: <br />1. Lot Area. To allow an accessory dwelling, flag lots shall contain at <br />least 12,500 square feet, excluding the pole portion of the lot, and <br />shall have a minimum pole width as required under EC <br />9.2775(5)(e). All other lots shall contain at least 6,100 square <br />feet. <br /> <br />(c) Area-Specific Accessory Dwelling Standards. The following standards <br />apply to all new attached or detached accessory dwellings in the R-1 <br />zone within the city-recognized boundaries of Amazon Neighbors, <br />Fairmount Neighbors and South University Neighborhood Association: <br />1. Lot Area. To allow for an accessory dwelling, the lot shall contain <br />at least 7,500 square feet. <br /> <br /> <br />9.2775 Residential Flag Lot Standards for R-1, R-2, R-3 and R-4. <br />4) Use Regulations. Residential flag lots have the same land use regulations <br />as the base zone except: <br />(b) Accessory dwellings are not allowed on flag lots less than 12,500 <br />square feet. <br /> <br />Findings: Lot area minimum standards are regulations relating to siting because they set out the <br />necessary specifications for sites on which an accessory dwelling can (and cannot) be placed (identifying <br />“the local position of a building to be constructed” or “the space of ground to be occupied by a <br />building”). <br /> <br />Regarding EC 9.2751(17)(a)1. and EC 9.2775(4)(b), requiring that a flag lot be at least 12,500 square feet <br />to allow for an accessory dwelling is reasonable because flag lots are already serving as a form of infill in <br />a neighborhood, and a potential for doubling that impact again with an accessory dwelling raises <br />concerns about impacts on surrounding properties and Goal 14 livability. Similar to alley access lots, flag <br />lots are typically created out of what was the backyard of a single-family dwelling. Limiting the size of <br />lot area where accessory dwellings are permitted potentially lessens impacts on surrounding properties. <br />The provision that all other lots contain at least 6,100 square feet is reasonable because it provides for <br />little more than adequate room for a primary and accessory dwelling with a reasonable amount of <br />yard/open space (and possibly parking) without causing overcrowding. The City has a responsibility to <br />balance the need for affordable housing and the efficient use of land with the need for communities to <br />be livable. <br />September 16, 2019, Work Session – Item 1
