NO.1 10/18/05 and/or movement of the water to topography not primarily shaped by the presence of water. In a given stream, pond, or other water body, the line of ordinary high water is the line on the bank or shore to which seasonal high water rises annually identified in the field by physical characteristics that include one or more of the following: a. A clear, natural line impressed on the bank by the presence of water, flowing water or waves. b. Changes in the characteristics of soils. c. The presence of water-borne litter and debris. d. The uppermost limit of destruction of terrestrial vegetation by the presence of water, flowing water or waves. If reliable water level data are available for 3 or more consecutive previous years, the line of ordinary high water can be considered the mean of the highest water level for all years for which data is available. Conservation setback distances measured from the line of ordinary high water are as follows: Resource Conservation Setback Category A Streams 120 feet Category B Streams 75 feet Category C Streams 50 feet Category D Streams 25 feet Category E Streams no conservation setback (2) Except as provided in Subsections (5) and (6), the 2 components areas of the /WR conservation area for water features identified as wetlands fiLb.e. Drotected in the Goal 5 Water Resources Conservation Plan are described and defined as follows: (a) The Goal 5 Water Resource Site. (b) The area within the applicable conservation setback. The conservation setback for a particular site is determined based on whether it is a Category A, B or C wetland in the Goal 5 Water Resources Conservation Plan. Conservation setback distances for wetlands are measured horizontally from wetland boundaries established under the "Goal 5 Locally Significant Wetland Sites Within the Eugene Urban Growth Boundary" map or if provided by the property owner, from the jurisdictional wetland boundary accepted by the Oregon Department of State Lands. Conservation setback distances are as follows: Resource Conservation Setback Category A Wetland 50 feet Category B Wetland 25 feet Category C Wetland no conservation setback (3) To determine the /WR conservation area for sites in which wetlands exist along with either an upland wildlife habitat site or a riparian site, the /WR conservation area for each of the individual water features shall be calculated and mapped separately, and the total footprint of all the individual/WR conservation areas combined shall be the /WR conservation area for that site. (4) The /WR conservation area for properties having the S-RN Royal Node Special Area Zone and the /WR Water Resources Conservation Overlay Ordinance - 6
