    We will be periodically posting and sending out "Tips" to help you select and apply BMPs in the most effective manner.  These tips are based on my experience - Iv'e actually built them, monitored the applications, and then given a lot of thought on how to make them better.  This is my opinion only.

    This BMP Toolbox is a concept I use for teaching Been waiting 25 years for runoff to flow "through" a straw bale!! If you want effective sediment control then think - "Stokes Law".Even the best geotextiles will "blind" and plug up, then you end up ponding water or they fail. Ask yourself, does a silt fence actually "filter" sediment-laden runoff?


    Still time to sign up for the UC Davis Extension Course: Sustainable Erosion Control:Effective Best of the BMPs  

    This course will present the "art and science"of proper BMP selection and will be presenting new concepts of sustainable erosion control and advanced implementation. Enroll at the following link:


    Repairing Urban Streams - One Day Training at StormCon in Austin  


    This one-day course will be offered as part of the conference  in Austin, Tx on August 3, 2015.

    Instructors:   John McCullah, Watershed Geologist and David Derrick, Potomologist

    This course will deal with some of the tools needed to design and build naturally-functioning stream, river, and creek reaches.  The material will be presented with the extensive use of Case Studies.  John McCullah will present projects utilizing Bioengineering and Environmentally-Sensitive techniques from US, and Canada, to New Zealand, some spanning over 15 years. John will also use some Dirt Time Video Clips to present projects. You can almost smell the diesel and dust!
    Urban stream entrenchment, incision, and degradation are a high-priority, national issue leading to poor water quality, loss of riparian function, loss of aquatic habitat and costly threats to infrastructure. The new provisions of the Clean Water Act are an attempt to deal with these issues.  Post-construction BMPs and revegetation requirements, along with LID and other reductions of hydromodification during development and construction are now required as part of the NPDES program.
    Tire revetment was once "new technology", now known to exacerbate the problems!

    David and John helpng students "read the stream" during a workshop at Shasta College's Stillwater Creek

    Sulphur Creek is Redding CA has received over $1.2 million in grant funding for Urban Salmonid Stream Restoration since 1996.

    Not just urbanization but also other anthropogenic factors such as dams, heavy long-term grazing, highly roaded timber areas, and instream gravel mining.  Urban streams which are “properly functioning”, are often mimicking pre-development conditions - with healthy stream buffers, riparian zones, and instream function that can often ameliorate the effects of urbanization and other anthropogenic land use problems.
    David Derrick will present many projects from his extensive collection of stream projects.  David will have a focus on using the Channel Evolution Model , grade control, and building Engineered Riffles “under compression”.  David also has 2 interesting case studies from the Austin area that also feature grade control.

    Attendees will get extraordinary value in addition, John will provide a free copy of NCHRP Report 544 - Environmentally Sensitive Streambank Stabilization Techniques Manual on CD.  This report, authored by J. McCullah, D. Gray, and D.F. Shields was published on CD and includes over 50 Techniques, from re-directive Rock Vanes and Bendway Weirs to Vegetated Rip Rap and Longitudinal Stone Toe with Live Siltation. It incorporates design considerations, construction specifications and detailed drawings - in AutoCad/Microstation files, and is sold on WYD site for $199.  David will make available his invaluable library of presentations to all attendees.

    Our BMP Summit Was a Huge Success.

     Friday and Saturday, May 1st and 2nd was our first combined effort to bring this summit to Redding. The two-day workshop sponsored by Shasta College, Sacramento Watersheds Action Group (SWAG), and Western Chapter International Erosion Control Association success exceeded our expectations. 

    Our highly acclaimed instructors John McCullah - Mr. DirtTime himself and David Franklin did an awesome job. We counted 55 in attendance, our thanks to everyone who attended.

     Dave Franklin

    Our Showcase Exhibitors were as follows;

    Heavyweight Sediment Control Solutions - Richard Quinley & Kristin Parkinson
    EarthSavers - Lynn Friesner and Howard Schau
    LSC Env. Products - Troy Duxbury and Robert Curl
    HydroStraw - Ed Lee
    Other exhibitors were: Zanker Road Resource Management - Aaron French, Contech Engineered Solutions - Curtis Kruger, Profile Products - Erik Schmidt, Steve Riggs  


     Now the fun starts! Day two-out in the field.




     One of our attendees shared his thoughts with us:

    I understand this was the first Erosion Control Workshop that you have put on at the Shasta College and wanted to give you my feedback. The information and presentations that you and David delivered were extremely relevant and very well done. I find all too often that people get “comfortable” with what they know and/or don’t get opportunities to learn about new solutions. For this reason, I believe the your event went extremely well. Honestly I attended a 5 day conference earlier this year where there were significantly less takeaways than your 2 day event.

     Don't miss the next one, we will be posting when and where it wll be.



    The two-day workshop sponsored by Shasta College, Sacramento Watersheds Action Group (SWAG), and Western Chapter International Erosion Control Association May 1st and 2nd.
    What are the Tools of Compliance?
    This workshop is about the BMPs!  Effective erosion and sediment control is rooted in a fundamental and comprehensive understanding of physical processes and basing the selection of Best Management Practices (BMPs) on those processes.  We will learn why now, with the new regulations (the Construction General Permit), more than ever before your BMPs must be “EFFECTIVE”.  And how, now, the SWPPP developers, the implementers, the contractors, the regulators, and the inspectors must acquire education and training and then demonstrate that knowledge through certifications.  This workshop is intended to de-mystify the BMP selection process, the SWPPP, while learning about the importance of Drainage, Infiltration, Rooting Depth, Grading for Erosion Control, and some Steep Slope applications. 

    Just a walk away is the Shasta College Erosion Control Training Facility featured in many research studies, articles and often the backdrop for the Dirt Time videos series.  This is where we will spend the second day – actually watching and participating in BMP implementation.  Ever wanted to spray hydromulch?  This is your chance!
    Following registration, we will contact you to confirm and answer any additional questions you might have.  Don't have a credit card or would rather register by phone?  Give us a call or email at:  (530) 247-1600 or
    The two-day BMP workshop will offer:
    • Full Day classroom on Friday with John McCullah and David Franklin as your instructors.
    • On Saturday your instruction on BMPs will be out in the field - the Shasta College Erosion Control Training Facility as featured in the Dirt Time Video series
    • There will be a special topic section on road drainage design for low-volume roads, farm and ranch roads, and utility access roads
    • Exhibitors will present New Equipment, Products and Materials
    • a chance to Co-Mingle with other professionals who are on the quest for more knowledge in the world of erosion and sediment control
    • Fully catered Lunch on Friday and Saturday - thanks to Shasta College Culinary Arts
    • Coffee and snacks in the morning.
    After the workshop you will:
    • Understand the physical processes of erosion / sedimentation and accompanying BMPs.  
    • Know the “four" most effective erosion control practices, the relative costs and how to implement them.
    • Feel confident in reviewing and inspecting SWPPPs and BMPs.
    • Have the knowledge to effectively implement a erosion and sediment control plan
    • understand why some BMPs work and some don’t and are a waste of money - money that can be spent on effective strategies.
    • Know how sediment control really works.
    • Install a silt fence with a static slicing machine.
    • Understand how Skimmer Outlets, Baffles and Flocculants can make sediment basins 90% effective
    • How to minimize or eliminate runoff from your site - increase infiltration, decrease discharges, establish vegetation
    • Be able to approach your project with the end in sight - getting stabilization and your Notice of Completion
    Also in Redding - On Thursday - EnviroTech NPDES Services w/David Franklin will also be offering a Class on the Industrial General Permit and Sampling Techniques.
