Findings Addressing ORS 197.312(5) September 3, 2019 9 <br /> <br /> <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 />5. Minimum Attachment. The standards at EC 9.2751(17)(a)4. are <br />applicable. <br /> <br />Findings: The requirement for a minimum attachment between an accessory dwelling and the primary <br />dwelling to be considered “attached” is related to design because it relates to the plan or scheme for <br />construction of the accessory dwelling. <br /> <br />It is reasonable to provide clarification as to what constitutes attachment to avoid someone from <br />claiming that a 2” by 4” board is sufficient to “attach” the accessory dwelling to the primary dwelling, <br />and only be subject to the standards that apply to “attached accessory dwellings.” Typically, attached <br />accessory dwellings have less external impacts, because they are a part of the primary dwelling, and <br />therefore have a lessor set of standards than detached accessory dwellings. <br /> <br /> <br />Prohibition on Alley Access Lots <br /> <br />9.2741 Special Use Limitations for Table 9.2740. <br />(2) Accessory Dwellings. Accessory dwellings are subject to the standards <br />beginning at EC 9.2750 and EC 9.2751, except that new accessory dwellings <br />are prohibited on alley access lots. <br /> <br />9.2751 Special Development Standards for Table 9.2750. <br />(18) Alley Access Lots in R-1. <br /> (a) General Standards. <br />2. Use Regulations. Alley access lots have the same land use <br />regulations as the base zone except that there is no allowance for <br />an accessory dwelling. <br /> <br />Findings: The prohibition on siting an accessory dwelling on an R-1 lot if the lot does not have street <br />frontage and can be accessed only from an alley is a regulation relating to siting. It relates to the location <br />of buildings, specifically those that are proposed for location on an alley; it relates to the ground that <br />may be occupied by an accessory dwelling. <br /> <br />ORS 197.312(5)(b) specifically makes the allowance of accessory dwellings subject to local regulations. <br />Although this regulation does make an accessory dwelling a prohibited use on some lots, it is reasonable <br />because it is necessary to addresses the impacts of a potential doubling of the number of vehicular trips <br />on city alleys that are not typically improved to a level to support such traffic. It also helps ensure that <br />the increased densities on these inherently small lots do not create “livability” issues that arise when <br />residential neighborhoods become overcrowded with unregulated infill. Livability issues must be <br />balanced with growth for the welfare of a community’s members. Goal 14 is “[t]o provide for an orderly <br />and efficient transition from rural to urban land, to accommodate urban populations and urban <br />employment inside urban growth boundaries, to ensure efficient use of land, and to provide for livable <br />communities.” Development on alley access lots can be more impactful to surrounding properties <br />because they are generally small lots surrounded by homes on three sides. The existing alleys are within <br />the older neighborhoods where there is a traditional grid pattern of blocks and streets along with older <br />homes that limits the location and overall size of alley access lots. The regulation is an effective way to <br />September 16, 2019, Work Session – Item 1
