About Meadowbrook
Deep, moderately well drained soils formed in alluvium and glacial outwash derived from mixed granitic and volcanic rock sources. Found on outwash plains, high terraces, and mountain valley floors at 4,000–7,000 ft elevation.
K factor values are sourced from the USDA Natural Resources Conservation Service (NRCS) SSURGO database.
Using Meadowbrook 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 Sierra, Nevada, and Plumas counties in the broader Sierra Nevada. Supports productive meadow and coniferous forest land uses in the mountain valleys.

Meadowbrook soil FAQ
What is the K factor for Meadowbrook soil?
Meadowbrook has a listed K factor of 0.28 in the Rapid RUSLE soil directory. Confirm final values against project specific soil survey data before submitting permit documents.
Where is Meadowbrook soil found in California?
Meadowbrook is mapped in Nevada, Plumas, Sierra. County mapping is based on available soil series data and should be verified for the exact project location.
How is Meadowbrook used in RUSLE erosion calculations?
Use the Meadowbrook K factor as the soil erodibility input in RUSLE or RUSLE2, along with rainfall, slope, cover, and support practice factors for the site.
