At the very least, this provision adds to the lack of clarity in the code. At worst, it could end up disallowing <br />additional dwellings that were previously permitted in the S-JW, reducing the housing allowed in the <br />neighborhood and exposing homeowners wishing to build a small additional dwelling on their lot to litigation <br />and appeals. <br />Density Requirements and Violation of the Metro Plan <br />During the course of the Council Work Session, it became clear that one goal of excluding SDUs from S-JW was <br />to preserve a density maximum of approximately 14 units per acre even in the face of potential additional code <br />changes.' However, such a goal is in violation of the Metro Plan, and additional ordinances or code changes to <br />further this goal exacerbates the S-JW's existing non-conformance with the Metro Plan. <br />There is no minimum or maximum density requirements specific to the S-JW; S-JW handles the number of <br />dwellings permitted on particular lots differently than elsewhere in the Eugene Code. The density permitted on <br />an individual lot in the zone varies widely dependent on the lot size.9 The underlying Metro Plan designation of <br />the area is Medium Density, which, according to Metro Plan policy A.910 should have density ranges between 10 <br />and 20 units per gross acre, which can translate to 14.28 to 28.56 units per net acre. <br />The S-JW permits densities well below those guidelines-by including only the maximum dwellings per lot, S-JW <br />permits development at densities lower than the guidelines in the Metro Plan (i.e. a 12,499 square foot lot <br />would be permitted to build a single unit, at a density of 3.49 units per net acre. A 4,499 square foot lot would <br />be prohibited from developing at the minimum density of 14.28 units per net acre.) <br />Furthermore, calculations made at the time of the passage of the S-JW indicate that the maximum possible <br />density in the zone, including all pre-existing development with more dwelling per lots than permitted by the S- <br />JW and presuming that all lots are developed to contain the maximum dwellings allowed, is 14.6 units per net <br />acre.11 However, this does not translate into properties being able to develop to the minimum required by the <br />Metro Plan. <br />Given the square footage of the various lots, the average permitted density is 13 units per acre, and the mean is <br />12.5 units per acre. Approximately 64% of the lots in the zone are not permitted to develop at densities above <br />14.28 units per acre, which is the minimum density permitted for Metro-Plan designated medium density areas. <br />neighborhoods. Even if the code permits two dwellings on lots over 6,100 square feet, the specific prohibitions on duplexes <br />prevent that "subset" of dwelling type on most R-1 properties, while continuing to allow two dwellings in a different <br />configuration (for example, a single-family home and SDU) on the lot. <br />' "With the general density perimeter of 14 units per acre, I think that has the chance to increase density beyond that." <br />Councilor Semple, May 23rd City Council Work Session <br />9 A 4,499 square foot lot would be permitted to develop to a maximum density of 9.68 units per net acre, while a 6,000 <br />square foot lot would be able to develop at a density of 14.52 units per net acre. <br />to Eugene-Springfield Metropolitan Area General Plan, 2004 Update Policy A.9, page III-A-7 "Establish density ranges in <br />local zoning and development regulations that are consistent with the broad density categories of this plan.... <br />Medium density: Over 10 through 20 dwelling units per gross acre (could translate to over 14.28 units per net <br />acre through 28.56 units per net acre depending on each jurisdictions implementation measures and land use and <br />development codes)" <br />11 5-JWJefferson Westside Special Area Zone Density and Goal 10 Land Supply Findings, submitted by Paul Conte, October <br />12, 2009. 15.3 units per net acre including all potential lot divisions <br />
