EXHIBITS Page 68 <br />supply exceeds the 1992-2015 residential land demand in all residential categories. <br />Assuming land is consumed evenly over the period, by 1999, there will be at least a 20- <br />year supply of residential land remaining inside the UGB. <br />Undeveloped residential land is considered unbuildable and removed from the supply if it <br />is within 230 KV powerline easements, the floodway, protected wetlands or wetland <br />mitigation sites in Eugene, wetlands larger than 0.25 acres in Springfield or buffers <br />around Class A and B streams and ponds. The remaining buildable residential land is <br />located primarily on the outer edge of the UGB and some of the buildable residential land <br />has development constraints such as slopes, floodplain, hydric soils and wetlands. <br />Development potential is reduced in Springfield on floodplain areas and in Eugene on <br />remaining potential wetlands due to moderate constraints that can support a less intense <br />level of development. <br />Anticipated federal regulations affecting fish habitats in the Pacific Northwest and new <br />applications for regulating under-designated, saturated, hydric soils by Oregon's Division <br />of State Lands, as well as other factors, make a definitive calculation of the buildable <br />land supply difficult. The adopted buildable land supply inventory represents the local <br />jurisdiction's best assessment of the amount of buildable land that will be available <br />within the UGB until the year 2015. <br />Laurel Ridge Record (Z 15-5) Page 631 <br />
