About Linne
Moderately deep, well drained soils formed in material weathered from calcareous shale and sandstone. Calcareous throughout. Found on hills and uplands with slopes of 9 to 50 percent.
K factor values are sourced from the USDA Natural Resources Conservation Service (NRCS) SSURGO database.
Using Linne 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
Widespread on the inner Coast Ranges in San Luis Obispo, Monterey, and San Benito counties. Dominant soil on many of the dry interior hillsides used for dryland grain farming and range livestock production.

Linne soil FAQ
What is the K factor for Linne soil?
Linne has a listed K factor of 0.37 in the Rapid RUSLE soil directory. Confirm final values against project specific soil survey data before submitting permit documents.
Where is Linne soil found in California?
Linne is mapped in Monterey, San Benito, San Luis Obispo. County mapping is based on available soil series data and should be verified for the exact project location.
How is Linne used in RUSLE erosion calculations?
Use the Linne K factor as the soil erodibility input in RUSLE or RUSLE2, along with rainfall, slope, cover, and support practice factors for the site.
