Resources From Caltrans
Storm Water Quality Manuals and Handbooks
www.dot.ca.gov/hq/construc/stormwater/manuals.htm
Caltrans has produced a number of manuals which incorporate state and federal requirements for pollution prevention and water quality control and utilize best management practices.
These documents provide direction in preparing Storm Water Pollution Prevention Plans (SWPPP) and Water Pollution Control Programs (WPCP) and are designed for contractors, resident engineers and construction staff.
Document templates are included.
Construction Site BMP Fact Sheets
www.dot.ca.gov/hq/construc/stormwater/factsheets.htm
The two dozen construction site best management practices fact sheets in the SS (soil stabilization), SC (sediment control) and TC (tracking control) series describe techniques that can be used to control erosion.
From one to twelve pages in length, the fact sheets use simple illustrations and an outline format to present practical information on the purposes, appropriate applications and limitations of various techniques.
The fact sheets are all included in the Storm Water Quality Handbooks, Construction Site Best Management Practices Manual, March 2003, 257 pages,
www.dot.ca.gov/hq/construc/stormwater/CSBMPM_303_Final.pdf.
Highway Design Manual
Chapter 870 - Channel and Shore Protection - Erosion Control, May 2001, 57 pages
www.dot.ca.gov/hq/oppd/hdm/pdf/chp0870.pdf
The Highway Drainage Design chapters of the Highway Design Manual contain useful information, particularly Chapter 870, Channel and Shore Protection - Erosion Control.
The chapter lists resources and describes the department's design philosophy and design concepts.
Includes detailed figures and design formulas.
Construction Storm Water Pollution Prevention Bulletin
Storm Water Management Program
www.dot.ca.gov/hq/env/stormwater/publicat/const/
These bulletins are designed to aid all projects in complying with the National Pollutant Discharge Elimination System permit requirements through the use of best management practices.

Resources From Out-of-State
Erosion Control Handbook for Local Roads
Minnesota Local Road Research Board and Federal Highway Administration, 2003, 122 pages
www.lrrb.gen.mn.us/PDF/200308.pdf
Describes effective erosion control practices for low-volume roads.
Lengthy sections on erosion control during construction and permanent erosion control illustrate a wide variety of techniques.
Although written in accord with Minnesota regulations, most of the information is applicable to California, and can be used to navigate the National Pollutant Discharge Elimination System (http://cfpub2.epa.gov/npdes/) permit process.
Erosion Control with Recycled Materials
Timothy Barkley, Public Roads, March/April 2004
www.tfhrc.gov/pubrds/04mar/03.htm
Describes how the Texas Department of Transportation teamed up with the Texas Commission on Environmental Quality to pioneer the use of compost for erosion control.
Poor soil conditions prevail in much of the Lone Star state and re-vegetation following road construction is difficult.
A specification for compost was developed and a successful demonstration project was launched, proving the technique would work even in 40 mile-per-hour winds.
Economic benefits include a substantial market for compost (TxDOT is now the country's largest consumer of compost), while the environment gains from the diversion of organic materials, including manure, from landfills.
Compost Utilization for Erosion Control
University of Georgia College of Agricultural and Environmental Sciences, August 2001, 8 pages
pubs.caes.uga.edu/caespubs/pubcd/B1200.htm
Composting for erosion control is innovative and cost effective, uses recycled organic materials and can substantially reduce soil loss and prevent sediments from reaching water sources.
This paper describes proper specifications for compost and the two basic methods for using it, compost blankets and compost filter berms.
Soil Erosion Control after Wildfire
Colorado State University Cooperative Extension, April 2002, 6 pages
www.ext.colostate.edu/pubs/natres/06308.html
Fire season is here, and wildfires often make soil repel water, increasing the rate of runoff and soil erosion.
This fact sheet describes control techniques including reseeding, contour log terraces, straw wattles, silt fences, check dams, water bars and culverts.
Free Library Services
Public agency employees are encouraged to contact the Institute of Transportation Studies Library for reference services and loans.
Specialized services are provided free, to employees of California-serving public transportation agencies at the local, state and regional levels, and federal agencies located in-state, with funding from the California Local Technical Assistance Program (LTAP).
