Elliott Spawning Channel | Parametrix
​Elliott Spawning Channel 
Renton, Washington

The Elliot Spawning Channel was constructed nearly a decade ago along the Cedar River to mitigate dredging activities at the mouth of the river and in proximity to the Renton Airport. Several areas of the channel banks were severely eroded, and the area had heavy underbrush and woody debris due to flood events. Parametrix provided topographic mapping support for design and hydraulic mapping and hydrographic surveying. Data was converted from LiDAR, bathymetry, and ground survey to GIS and CADD.
