Renton
silt loam

Mapping Symbols: Re

The Renton series consists of poorly drained soils that formed in alluvium in river valleys. Slopes are 0 to 1%. The annual
precipitation is 35 to 55 inches. The frost-free season is about 200 days.

Typical Profile:
Depth from Surface:
0 to 6 Inches: Dark grayish-brown very sandy loam
6 to 60 Inches: Black sand 

Permeability: Moderately rapid in surface and very rapid in subsoil

Rooting Depth: 60 inches + if drained

Depth to Seasonal High Water Table: 1 to 2 feet

Available Water Holding Capacity: Moderate to moderately high

Runoff Potential: Slow 

Erosion and Slippage Hazard: Slight

Use and Management: Primary use of this soil is for row crops, seeded pastures, and urban development. Pasture forage yields are 2.0 tons/acre/year if undrained and 4.0 tons/acre/year if drained with good management. Western Red Cedar, Douglas-fir, Western Hemlock, Red Alder, and Bigleaf Maple are important tree species on this soil. Plant competition is a limiting factor in timbering. The Renton soil has moderate recreational and severe engineering limitations due to its flooding potential.
