WebIn addition to the following, it should be noted that exceptions to typical values of soil properties occur often. All foundations must have a factor of safety applied for design purposes (typically between 2 and 4). Foundations typically need to be taken down to a depth where seasonal changes and plant life will not affect the soil properties.

WebPermeability is the rate at which fluid can move through the soil. Hydraulic conductivity is the flow of water in a porous medium. Permeability is the amount of water that can pass through a porous material. The hydraulic conductivity symbol is “K”. The symbol used to represent Hydraulic permeability is P. WebThe potential for surface water runoff is medium. Saturated hydraulic conductivity is moderately high to high (4.23 to 14.11 micrometers per second). Permeability is moderate. The depth to a seasonal high water table is more than 183 cm ... Particle size data are on file for several pedons of the Worthen soils at the NRCS MLRA Office Region 11.
