FLOW_LEVEL From King County	Description 2005 SWDM Flow Control Application designation. Domain Basic Flow - Areas where King County has determined that maintaining peak flows is sufficient to protect natural and constructed conveyance systems. Conservation Flow - The default designation until a County-approved plan or study has determined that natural and manmade conveyance systems within the area are not sensitive to development-induced increases in runoff volume and durations. Flood Problem Flow - Areas where the County has determined that a higher than average level of flow control is needed to prevent aggravation of existing documented flooding problems.
OBJECTID From ESRI	Description Internal feature number. Domain Sequential unique whole numbers that are automatically generated.
Shape From ESRI	Description Feature geometry. Domain Coordinates defining the features.
Shape.STLength() From Esri	Description Feature geometry. Domain Coordinates defining the features.
SHAPE From ESRI	Description Feature geometry. Domain Coordinates defining the features.

1/24/2005	This dataset was created by rating the King County Water and Land hydrological basins by several flow related characteristics such as flooding problems and runoff/drainage issues. The basins were given an overall score and then dissolved to create larger areas with the same score/designation. The incorporated areas (as of 1/03/05) and areas overlapping the forest production districts were removed.
