The Office of Hydraulics and Stormwater Design emphasizes stewardship of California's water resources by providing:
The above link above opens a file which includes the main report with text, tables, equations, and figures. The file is about 976 kilo-bytes and fits on a standard 1.44 M floppy disk. Chapter 5 of the report documents the California Bank and Shore (CaBS) layered rock slope protection (riprap) design method.
Update 1 replaces Appendix A of all 3 prior editions, and it is about 271 kilo-bytes. Three solved problems (CaBS layered RSP design method) were retained along with assumptions, dimensions, calculations, and figure references. The term “bankfull” was replaced with “full channel depth”. Problem-specific and generic figures were revised for clarification. Expressions and steps for changing the minimum dimensions of a MOUNDED Toe were revised. There is a discussion and general procedure for designing a granular filter using the Terzaghi design criteria. In problem 3 (concreted-RSP) terminology is consistent with the Caltrans Highway Design Manual. Figure A-9 was revised, and there is now an equation for estimating concrete volume. Based on 10 years of consultations with engineers in the public and private sectors, there are “Additional Topics” and figures. The “Additional Topics” are : Verifying Individual Rock Weights and RSP-Class, Guidelines for RSP Volume and Weight (with suggested values for porosity of revetments), RSP Toe (Scour and Embedded Depth, Mounded Toe, Bedrock), RSP Tolerance, Method A or Method B, Notes on ASTM Riprap Guide, and RSP (riprap) Monitoring. New Figure A-10 illustrates protruding and non-protruding revetments. New Figure A-11 has alternative dimensions which may be considered for a CaBS mounded toe. New Figure A-12 illustrates a stable toe design in bedrock.
Field-evaluations are documented of riprap sites in five states : Washington, Oregon, California, Colorado, and Mississippi. Appendix C (Jan 2004) stands alone from the main report. There are 90 captioned color photo images with improved quality (300 dots per inch) as contrasted to prior editions. The captions describe design, construction, and maintenance issues of riprap and related features.
The second edition of the final research report, Gabion Mesh Corrosion Field Study of Test Panels and Full-scale Facilities (November 2001) was intended for distribution as a paperless report.
All of the conclusions and all of the recommendations in both editions are identical. For general guidance see CONCLUSIONS (last paragraph of page 99, all of page 100), RECOMMENDATIONS (pages 101 through 105), and APPENDIX A (pages 110 and 126). Owners of the first edition (May 2001) should replace pages 16, 56, and 107. The cover, signature, and Technical Report Documentation pages were changed to reflect the November 2001 date. A few other pages have minor corrections. All of the photos were darkened to improve the images.
Printed (hard-copy) reports are not available from Caltrans.

The Office of Hydraulics and Stormwater Design is the sponsor for water pollution control and temporary construction site BMP special provisions. Any proposed new specifications or significant modifications to the following must be reviewed by the Office of Hydraulics and Stormwater Design for concurrence. Please follow the sponsor request and concurrence process for non-standard special provisions (nSSPs).

Sample Concurrence Memo
In order for Office of Hydrualics and Stormwater Design review and approve the use of the Treatment BMP (TBMP) nSSPs we need a complete package, which includes the following:
In email - submit milestone dates of project especially critical dates our office needs to know.
The Construction BMP Cost Estimator Excel file is used to help prepare information for Construction Division concurrence submittal.
The North Region developed this spreadsheet and other districts are encouraged to use it.
The guidance and specifications being provided are the result of collaboration between members of the pervious pavement team that included various HQ Functions and Industry.
The goal of developing this guidance was to have consistent methods, siting criteria, and material specification, when considering the use of pervious pavement within Caltrans right of way. Caltrans now has the ability to install this type of stormwater feature. Currently pervious pavement can only be considered within Caltrans right of way at non-highway facilities (Rest Areas, Park and Rides, etc.) including Maintenance Vehicle Pullouts on highway facilities.
As described in the guidance, approval from HQ Hydrualica and Stormwater Design and HQ Maintenance is required before pervious pavement can be included in a contract or constructed within Caltrans right of way. By requiring these approvals (gate keeper approach), an evaluation can occur related to appropriate feasibility and maintainability.
When a location is approved for use, it will be tracked similar to a pilot project to evaluate construction methods (potential specification improvements) and maintainability (to assure that proposed maintenance procedures will be adequate).
When pervious pavement is being proposed as a viable BMP the Pervious Pavement Design Guidance will provide the consistency needed for an appropriate evaluation.
This interim guidance covers RUSLE2 Erosion Prediction for SWDR, final stabilization certification, NOT filing, etc. based upon sediment risk. This guidance was developed in response to Action Item 10-15 from the Project Design Storm Water Advisory Team (PD SWAT) meeting of May 11, 2010.
In 2013, the State Water Resources Control Board (SWRCB) issued a National Pollutant Discharge Elimination System (NPDES) permit that regulates stormwater discharges from Caltrans facilities. The permit requires Caltrans to maintain and implement an effective Stormwater Management Plan (SWMP) that identifies and describes the Best Management Practices (BMPs) used to control the discharge of pollutants to waters of the United States.
This Guide describes the process for Caltrans staff to incorporate the BMPs from the SWMP into the planning and design phases of a project. It is important to note that this guide provides only minimum guidelines, and that Stormwater controls other than what are included may need to be incorporated on a project-by-project basis to comply with special requirements from a Regional Water Quality Control Board. This Guide may be updated as needed to reflect changes to the SWMP.
