Final Erosion Prediction Procedure for Caltrans RUSLE2

A process is presented for estimating surface erosion on slopes in conjunction with selecting soil stabilization and sediment control BMPs. Methods for collecting and documenting climate, soil, topography, vegetation, and BMP selection are given. The Revised Universal Soil Loss Equation (RUSLE2) is used to estimate erosion for pre-construction, construction, and post construction phases.

Compost Reconnaissance Study

This study consists of a literature search and several technical memos intended as a "mythbusters" to remove institutional roadblocks preventing greater use of compost on Caltrans projects. The study is available upon request from the HQ Office of Hydraulics and Stormwater Design.
