Linear feature, vegetated, and designed to spread water out over a large surface area. There are also different component types of swales as well.
For more information about this layer please see the <a href='https://www5.kingcounty.gov/sdc?Layer=SW_WQ_SWALE_LINE' rel='nofollow ugc'>GIS Data Catalog</a>.<br /><br />Component Types-Basic biofiltration swale: A long, gently sloped, vegetated ditch designed to filter pollutants from stormwater. Grass is the most common vegetation, but wetland vegetation can be used if the soil is saturated. -Wet biofiltration swale: A variation of the basic biofiltration swale used where the longitudinal slope is slight (1 to 2 percent or less), water tables are high, or continuous low base flow is likely to result in saturated soil conditions. Under such conditions, healthy grass growth is not possible and wetland plants are used to provide the biofiltration mechanism.-Continuous inflow biofiltration swale: A biofiltration swale where water enters the swale continuously at numerous discrete inflows with no single inflow contributing more than about 10% of total swale flow.

Data dervied from multiple legacy data sources and is continually updated
Edits undergo a peer review process wherein the completeness and omission of assets are assessed.
Peer review.
Legacy data were collected with GPS instruments and the locations were not carefully reviewed. The current process for collecting and editing data involves picking visible assets (e.g. a catch basin grate) from the aerial or georeferencing design plans. Snapping is used to position the asset at the intersection of two line features, on a point feature, or at the end of a line feature.
Peer review with aerial imagery.
Mapping practices must adhere to established guidelines in our Standard Operating Procedures (SOPs).
Assets undergo a peer review/QAQC process and are validated with a nightly script.
Assets undergo a peer review/QAQC process.
Data is validated through a nightly script but does not prevent data with errors from being published. These errors should be corrected during the peer review process.
