About Yokohl
Moderately deep, well drained soils formed in colluvium and residuum weathered from metavolcanic rocks and schist. Found on rolling to steep foothills on the western flank of the Sierra Nevada and Tehachapi Mountains.
K factor values are sourced from the USDA Natural Resources Conservation Service (NRCS) SSURGO database.
Using Yokohl in a RUSLE calculation
For a California construction project, use the soil K factor with rainfall erosivity, slope length and steepness, cover management, and support practice inputs. The K factor represents the soil erodibility portion of the model, so selecting the soil series that matches the site is important for defensible stormwater documentation.
In a SWPPP workflow, the practical question is not just what soil type is mapped near the project. It is whether the mapped series, K factor, and drainage assumptions match the site evidence well enough to support the RUSLE or RUSLE2 calculation.
California Distribution
Mapped in Tulare and Kern counties on the interior foothills bordering the southern San Joaquin Valley. Used primarily for range livestock production; supports blue oak and annual grasses.

Yokohl soil FAQ
What is the K factor for Yokohl soil?
Yokohl has a listed K factor of 0.32 in the Rapid RUSLE soil directory. Confirm final values against project specific soil survey data before submitting permit documents.
Where is Yokohl soil found in California?
Yokohl is mapped in Kern, Tulare. County mapping is based on available soil series data and should be verified for the exact project location.
How is Yokohl used in RUSLE erosion calculations?
Use the Yokohl K factor as the soil erodibility input in RUSLE or RUSLE2, along with rainfall, slope, cover, and support practice factors for the site.
