Oregon Administrative Rules › Chapter 141 - DEPARTMENT OF STATE LANDS › Division 86 - WETLAND CONSERVATION PLAN › Section 141-086-0200 - Definitions

Current through Register Vol. 63, No. 7, July 1, 2024
(1) "Cowardin class
			 or subclass" means the wetland classification according to the U.S. Fish and
			 Wildlife Service's
Classification of Wetlands and Deepwater Habitats of
			 the United States
, Cowardin et al., 1979.
(2) "Director" means the Director of the
			 Oregon Department of State Lands or designee.
(3) "Department" means the Oregon Department
			 of State Lands.
(4) "Georeferenced"
			 means linking geographic data to known coordinates on the surface of the
			 earth.
(5) "GIS" or "Geographic
			 Information System" means a system of hardware, software and data storage that
			 allows for the analysis and display of information that has been geographically
			 referenced.
(6) "HGM class and
			 subclass" means the hydrogeomorphic classification of the wetland based upon
			 its landscape position and hydrology characteristics, according to the HGM
			 classification developed by the Department.
(7) "Indicator" means the soil, vegetation,
			 and hydrology characteristics or other field evidence that indicate that
			 wetlands are present.
(8)
			 "Inventory" means a systematic survey of an area to identify, classify and map
			 the approximate boundaries of wetlands, and includes the supporting
			 documentation required by these rules.
(9) "Mapping" means representing the
			 identified wetlands and their approximate boundaries on a map.
(10) "Offsite Determination" means a wetland
			 determination conducted without field verification using NWI maps, soils maps,
			 and aerial photographs.
(11) "Other
			 Waters" means waters of the state other than wetlands, such as streams and
			 non-vegetated ponds.
(12) "Probable
			 Wetland" or "PW" means an area noted during the course of LWI development that
			 appears to meet wetland criteria but is less than one half of an acre in size
			 or is small and of undetermined size, and is mapped as a point rather than a
			 polygon on the LWI maps.
(13)
			 "Sample Plot" means a specific area on the ground where soils, vegetation and
			 hydrology data are recorded on a field data form per OAR 141-90-0035(14) in
			 order to make a wetland determination.
(14) "Statewide Wetlands Inventory" or "SWI"
			 means an inventory that contains at minimum the location, type (e.g.
			 classification) and approximate extent of wetlands in the State of Oregon. This
			 inventory is continually revised as additional information is received or
			 obtained by the Department.
(15)
			 "Stream" means a watercourse created by natural processes, or one that would be
			 in a natural state if it were not for human-caused alterations. Stream includes
			 a channelized or relocated stream.
(16) "Visually confirm" or "visual
			 confirmation" means to walk over and/or visually check an area to make a
			 wetland determination and map wetlands and other waters.
(17) "Wetlands" means those areas that are
			 inundated or saturated by surface or ground water at a frequency or duration
			 sufficient to support, and that under normal circumstances do support, a
			 prevalence of vegetation typically adapted for life in saturated soil
			 conditions (ORS 196.800(16)).
(18) "Wetland Delineation Report" means a
			 written document that contains the methods, data, conclusions and maps used to
			 determine if wetlands and/or other waters of the state are present on a land
			 parcel and, if so, describes and maps their location and geographic extent. A
			 wetland determination report documenting wetland presence or absence is
			 included within this definition (OAR 141-090 et seq.).
(19) "Wetland Determination" means a decision
			 that a site may, does, is unlikely to, or does not contain wetlands. A
			 determination does not include the precise location or boundaries of any
			 wetlands determined to be present (OAR 141-090 et seq).
(20) "Wetland Mosaic" means a complex of
			 several wetlands that are interspersed between areas of non-wetland each less
			 than one half of an acre in size, or less than one tenth of an acre in size for
			 a WCP, making them difficult to map.
