About Rincon
Deep, moderately well drained soils formed in alluvium derived from sedimentary rocks. Found on terraces and alluvial fans with slopes of 0 to 9 percent.
K factor values are sourced from the USDA Natural Resources Conservation Service (NRCS) SSURGO database.
Using Rincon 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
Common in the coastal valleys of Santa Barbara and Ventura counties. Used extensively for avocado and citrus orchards.

Rincon soil FAQ
What is the K factor for Rincon soil?
Rincon 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 Rincon soil found in California?
Rincon is mapped in Santa Barbara, Ventura. County mapping is based on available soil series data and should be verified for the exact project location.
How is Rincon used in RUSLE erosion calculations?
Use the Rincon K factor as the soil erodibility input in RUSLE or RUSLE2, along with rainfall, slope, cover, and support practice factors for the site.
