EXHIBITS Page 72 <br />A.5 Develop a monitoring system that measures land consumption, land values, housing type, <br />size, and density. Reports should be made to the community on an annual basis. <br />A.6 Eugene, Springfield, and Lane County shall encourage a community dialogue, when the <br />annual monitoring report on land supply and housing development is made public, to <br />address future Periodic Review requirements that relate to meeting the residential land <br />supply needs of the metropolitan area. <br />A.7 Endeavor to provide key urban services and facilities required to maintain a five-year <br />supply of serviced, buildable residential land. <br />A.8 Require development to pay the cost, as determined by the local jurisdiction, of extending <br />public services and infrastructure. The cities shall examine ways to provide subsidies or <br />incentives for providing infrastructure that support affordable housing and/or higher <br />density housing. <br />Residential Density <br />Findings <br />14. Housing costs are increasing more rapidly than household income. With rising land and <br />housing costs, the market has been and will continue to look at density as a way to keep <br />housing costs down. <br />15. Recently approved subdivisions are achieving lot sizes on flat land averaging 7,400 <br />square feet in Eugene and 7,800 square feet in Springfield. Comparing the net density' of <br />all Eugene-Springfield metropolitan single family-detached units in 1986 and 1994 <br />indicates that in 1986 the net density was 4.12 units per acre which equates to a 10,573 <br />square foot lot while in 1994, the net density was 4.18 units per acre or a 10,410 square <br />foot lot. These trends indicate that development in low-density is achieving assumed <br />density expectations. <br />16. Although single-family detached lot sizes are decreasing, the Metro Plan targeted <br />residential densities for all new development are not being achieved at this time. The <br />Metro Plan assumes a net density of 8.57 units per acre (note: translation from 6 units per <br />gross acre) for new development over the planning period. For new dwelling units <br />constructed during 1986 to 1994, the net density was 7.05 units per acre based on the <br />Regional Land Information Database of Lane County (RLID). The estimated average <br />overall residential net density for all residential development has climbed from 5.69 units <br />per acre in 1986 to 5.81 units per acre in 1994. <br />a Density (Net): The number of dwelling units per each acre of land, excluding areas devoted to dedicated streets, <br />neighborhood parks sidewalks, and other public facilities. <br />s Density (Gross): The number of dwelling units per each acre of land, including areas devoted to dedicated streets, <br />neighborhood parks, sidewalks, and other public facilities. <br />Laurel Ridge Record (Z 15-5) Page 635 <br />
