    IECA Names its Environmental Achievement and Outstanding Professional of the Year for 2015.


    Denver, Colo. – International Erosion Control Association Region One (IECA) names its 2015 winners for the Environmental Achievement and Outstanding Professional of the Year awards. The Bijou Area Erosion Control Project receives the Environmental Achievement Award and John McCullah is named the Outstanding Professional of the Year award recipient.

    The Environmental Excellence Award is the IECA's premier award. It recognizes an outstanding stormwater and erosion and/or sediment control project, program or operation that demonstrates excellence in natural resource conservation and environmental protection. Recipients of this award show a high‐level of environmental benefit by clearly identifying the objectives, methods used, results obtained and details of the benefits to the environment. Accepting the award for the Bijou Area Erosion Control Project will be Stephen Peck, PE, PMP, CPSWQ, QSD. 

    The Bijou Area Erosion Control Project is a complex regional stormwater pump‐and‐treat system in a Federal Emergency Management Agency (FEMA) ‐mapped flood zone. While the issues were complex, the system applied standard construction techniques in a series to provide efficient stormwater quality treatment and flood control in an effective and easily maintainable manner. To maximize the efficiency of the system, the project included a bypass stormwater double box culvert as a key component of the project. The box culvert conveys upper watershed runoff through the highly developed commercial core, and directly into Lake Tahoe, without contributions from the commercial and highway areas (runoff with high constituent loading). This approach allowed for more effective treatment of the commercial area runoff (significantly less flow/volume), which enters the pump‐and‐treat system. The bypass culvert system further included the design and construction of a headwall in the shore zone of Lake Tahoe, a federally protected water body.

    John McCullah is named the winner of the Outstanding Professional of the Year. This award recognizes an IECA member as an individual or organization that demonstrates excellence in their work in the industry and is viewed by his IECA peers as an industry leader through significant engagement with the IECA. McCullah has been in the industry for more than 30 years and during that time he has become a renowned industry expert whose influence spans the globe. In addition to working across the continental United States, McCullah has completed projects in exotic and dramatically different locations such as Malaysia and New Zealand.

    He is a teacher, a scholar, an activist and a professional; and in each of these roles he has made significant positive impacts on the industry in a number of ways over the years. These awards are selected on criteria that reflect quality, skill and environmental benefits. Winners were selected from responses to a “Call for Entries” process. Both winners will be recognized at IECA’s annual conference and expo, Environmental Connection 2016 in San Antonio, Texas on February 17. 

     About IECA

    Founded in 1972, the International Erosion Control Association (IECA) is a non‐profit organization devoted to serving as the premier global resource for the prevention and control of erosion and sediment related problems. IECA is the world's oldest and largest association devoted to helping members' solve erosion and sediment control problems. To sustain its mission, IECA hosts an annual conference for industry professionals, which includes continuing education on the latest technologies and findings, and the  industry's largest exhibit of related materials, products and equipment. In 2012, IECA formed Region One and Region Two. Region One consists of North America, South America and Europe; Region Two consisting of Africa, Asia and Australia.

    Take a cruise through some photos taken during the recent Erosion Control BMP Summit at Shasta College





    We are considering doing even more ‘application and performance’ studies and demonstrations at the Shasta College Erosion Control Training Facility In the near future.


    A couple of new and innovative products we are considering are a recycled polyethylene wattle (remember the DuraWattle was demonstrated at the Erosion Control BMP Summit back in May) and I discovered a newly engineered “rumble-strip-type” construction entrance.   Several manufacturers/vendors have been referred lately to us to do “trials” or studies at Shasta College at our future summits.
    Please let us know if you’d be interested in attending and or exhibiting at the SECOND Shasta College BMP Summit!  We, SC, SWAG, and WCIECA are planning another one for this winter.  Interested ?   Please contact to be put on our “interested list"

    We have some plans to test the mychorrizae fungi applications in establishing native grasses.
     Information, specifications, and guidelines for Using and successfully establishing CA native grasses is a Huge issue given the ‘Drought” and the concept of sustainable erosion control for construction sites only makes sense when you consider that the Construction General Permit  requires (favors) permanent vegetation establishment to get your Notice Of Termination.
    There is also a lot of discussion out there about pre-packaged hydraulic growth medium-type hydromulches with “biotic soil enhancers” and how these products can supplant the need for compost or topsoil applications.  I’d like to do some side-by-side comparative studies on our TEST SLOPES.                        
    Here are some photos how the Shasta College Erosion Control Training Facility looks currently.


    Here are some photos from the Hydromulch-compost study from 2009/2010.

    In the study we looked at the accuracy in the anecdotal theory that "high rates of BFM (4000#/ac) would reduce seed germination and grass establishment."  We constructed approximately 20 plots that has uniform soil prep (trackwalking), broadcast mychorrizae uniformly, then manually applied the CA native seed blend to the soil surface at a rate of 20#/ac.   The seed was then covered with several kinds of commonly used hydromulches - Soil Guard, Flexterra, TeraMulch, hydrostraw, and a cotton mulch. The study is available for free download by scrolling down to NAVIGATION and clicking on WYD Files.

    The plots were visually monitored for photodocumented for density of plant establishment during that first Winter, Summer, and the following Fall seasons. We documented NO discernible ill effects from higher rates.  Actually just the opposite!!! was true.  

    That particular winter had unusually intense storms and the lower rates of hydromulch resulted in quite a bit more erosion - there were small deltas of fine sediment observed at the bottom of the 2000#/ac plots, irregardless of mulch brand.  Subsequently we observed less vigorous and dense establihment on those 2000#/ac plots.

     Note the compost plot on the left, this is just two months after application.

    What is most significant is that we also applied a compost blanket 2" thick.  There was NO reduction of seed establishment, if fact the compost blanket grew the BEST grass, both by covering seed with 2" of compost and by gently raking the seed into the surface - there was no dicernable difference. 

     Hope you enjoy and hope this paper somewhat "lays to rest" the notions that Compost Blankets at 2"-thick and BFM at 4000#/ac will smother seeds.    We must, as EC Specialists, find a balance between veg establishment and effective erosion control during the establishment period.    

    Another observation made at this trial was that weeds did not become established on the plots, even though weeds grew almost everywhere else!  My personal hunch is that adding mychorrizae made the difference.  My theory is that California native, mychorrizal-dependant grasses and mychorrizae will "out compete" many of the commom noxious weeds. This could be another comparative study!!  Native grass establishment with and without mychorrizae. 

    Another potential study will be to do side-by-side comparisons of compost and the "new" biotic soil formulated hydromulches.  These hydromulches could prove to be cost-effective over compost.  Let's try it!!
