Sensitive Area Ordinance Streams

King County 1998 Sensitive Area Ordinance Streams One vector digital data King County, WA King County None withheld Streams are defined in the Sensitive Areas Ordinance (SAO) as those areas of King County where surface waters produce a defined channel or bed. A defined channel or bed is an area that demonstrates clear evidence of the passage of water and includes but is not limited to bedrock channels, gravel beds, sand and silt beds and defined-channel swales. The channel or bed need not contain water year-round. This definition is not meant to include irrigation ditches, canals, storm or surface water runoff devices or other entirely artificial watercourses unless they are used by salmonids or used to convey streams naturally occurring prior to construction in such watercourse. To provide guidelines for development. King County classifies streams into the following categories: Class 1 streams are those inventoried as "Shorelines of the State" under King County's Shoreline Master Program. Class 2 streams are those smaller that Class 1 streams that flow year-round during years of normal rainfall or those that are used by salmonids. Class 3 streams are those that are intermittent or ephemeral during years of normal rainfall and are not used by salmonids. Unclassified streams are those for which a water course has been identified but for which the defining characteristics of a Class 1, 2, or 3 stream have not been determined. Further study is necessary to classify these streams. The overall policy objective for strem management in King County is no net loss of stream functions and values. A detailed description of development standards for streams is given in the Sensitive Areas Ordinance and administrative rules. For exceptions, exemptions, and mitigation procedures for streams, please refer to the SAO and administrative rules. In general, the minimum required native vegetation buffer width for each stream class as measured from the ordinary high water mark is a follows: Class 1 Streams - 100-foot buffer Class 2 Streams used by salmonids - 50-foot buffer. A study may be required to determine salmonid use. Class 3 Streams - 25-foot buffer unknown publication date Complete None planned -122.542282 -121.671119 47.785043 47.130446 Not applicable enviro streams Not applicable King County, WA Pacific NW Washington state None King County data are made available with the understanding that they shall be used exclusively by the obtainer or his/her authorized agents. Digital products may not be reproduced or redistributed in any form or by any means without the express written authorization of King County. Because of seasonal variations in streamflow, the map folio does not represent a conclusive statement on stream classes. The majority of area have been field checked only once at a specific time of year. Weather conditions and stream flow affect the ability of field workers to locate fish. Research was also limited by environmental factors such as steep slopes and heavily vegetated areas that prevented access, and by restricted access to private property. This set of maps represents a compilation of the most thorough research on the location of and presence of salmonids in streams in King County as of 1990; however, some streams are not shown on these maps and many streams require further study to determine a final classification. Studies that are incomplete at this time, but will add to this information base, are the Washington Rivers Information System, on a Geographic Information System, managed by Washington Department of Wildlife and funded by Bonneville Power Administration; and a detailed survey of Newaukum Creek by Trout Unlimited.

The 1987 edition and earlier editions of the Sensitive Areas Map Folio used the Washington Department of Natural Resources (DNR) Water Type Maps as a basis for stream categorization. The 1990 edition uses the new stream classification system (described above) defined by the Sensitive Areas Ordinance (SAO). The DNR system is based on the potential for fish habitat as well as water use characteristics, while the SAO system depends on the actual documented existence of salmonids in a stream or documented evidence of the perennial or intermittent nature of a stream. Both classification systems define Type I or Class 1 streams as Shorelines of the State. Although the DNR Type II-VI streams may coincide with SAO Class 2, 3, and Unclassified streams, the DNR system does not translate consistently to the SAO classification system. Because the SAO classification system requires a knowledge of the actual presence or absence of salmonids, additional research was necessary on streams that had previously been mapped and on streams added to the maps. Sources used for the 1990 maps were: 1) The State Shorelines Act maps and regulations were used to identify all Class 1 streams. 2) A Catalog of Washington Streams and Salmon Utilization, published in 1975 by the Washington Department of Fisheries, and personal interviews with WDOF field biologists in 1990 provided locations of anadromous fish bearing waters, included in Class 2 streams. 3) Data from the King County Water Management Basin Reconnaissance Program maps, field notes and basin plans published since the 1987 map folio edition were incorporated. 4) Washington Department of Natural Resources Water Type Maps were used to identify streams for which fish use has not been determined but channels have been identified. The Water Type maps are the primary source for identification of Unclassified streams east of the Forest Zone line. 5) Field work was conducted from April through July, 1990, primarily in the Snoqualmie River Basin, upper Green River, and portions of the Enumclaw Plateau, areas which had not been previously surveyed intensively. The fieldwork consisted of mapping stream channels, and determining, where possible, the presence of salmonids, and whether or not the stream was perennial. withheld withheld withheld withheld withheld 1990 Convert to SDE feature class from 12/21/2005 Holly Orr DDES Metadata imported. withheld 20100712 11163900 Vector Simple FALSE 5452 TRUE FALSE coordinate pair 0.001000 0.001000 survey feet D_North_American_1983_HARN Geodetic Reference System 80 6378137.000000 298.257222 1.000000 Explicit elevation coordinate included with horizontal coordinates SAOSTREAM_line Line feature attribute table ESRI Feature Class 5452 OBJECTID Internal feature number.
