ESenSS: Environmentally-Sensitive Streambank Stabilization Manual w/ Disc

This manual contains 44 different channel and bank protection techniques in the categories of:

•    River Training
•    Bank Armor and Protection
•    Riparian Buffer and Stream Corridor Opportunities
•    Slope Stabilization

Someone who would be interested in ESenSS:

Watershed hydrologists, highway engineers, soil conservationists, biologists, restoration ecologists, and anyone like yourself who could utilize this tool in restoring stream and river systems, white protecting property and structures with the latest techniques.  

Each year, human activity and infrastructure places a higher impact on our surrounding environment. ESenSS includes increased knowledge of “soft” practices that provide engineers with the ability to restore ecological health and strength within the infrastructures that are so critical and important to human society.

ESenSS is user-friendly, with easy to read descriptions of the latest techniques used.

Detailed Auto-Cad drawings with reasoning behind techniques!

Colored, informative pictures on specific case studies with responsive outcomes!

 

ESenSS also includes the technique-selection software, "Greenbank," which is an innovative program for selecting and ranking appropriate stabilization and protection techniques based on a whole suite of site-specific conditions.

Muck Stabilization

 

Alameda/San Joaquin County

Mitchell's Ravine is (was) a tunnel muck site - a legacy of the  Hetch Hetchy Aqueduct from 1938. The water tunnel is about 600' under ground at this site!  San Francisco PUC-Hetch Hetchy and CA State Parks OHV Division, in conjunction with the RWQCB, were responsible for the collaborative mitigation/reclamation work.  The restoration plan for the 4+ acre site restoration was designed by John McCullah, geomorphologist and CPESC, Salix Applied Earthcare and engineering was completed by Fall Creek Engineering.  Neal Youngblood, Geologist Redwood National Park, provided invaluable expertise since this job was much like removing abandoned logging roads and landings.  Mike Vroman, Hetch Hetchy Right-of-Way Maintenance Manager, provided project oversight.

The waste pile, once entirely filling over 800-feet of the  "Ravine", has eroded episodically for over the last 70 years.  The eroded gravel-sized sediment has caused impacts, such as aggradation and erosion, downstream in downstream Mitchell's Ravine and Corral Hollow Creek. At least half of the "spoils" have eroded and moved downstream - some channel reaches have 'aggraded' by over 9 feet!  The restoration of the channel downstream is a story to be told in another blog, Stay Tuned! 

                                                                                                                                   

The stabilization of the remaining 20-30,000 CY was done onsite using "Landform Grading" strategies.  A 6-foot high rock toe wall was engineered for the left descending bank of the channel (approx. 800 feet) then the spoil material was placed above forming slopes that mimic the natural terrain and geomorphology.  Two natural drainages were continued through the "fill slopes".  See;  "Landforming: An Environmental Approach to Hillside Development, Mine Reclamation and Watershed Restoration", Horst J. Schor, Donald H. Gray, John Wiley & Sons, 2007

Cache Creek Before & After

John and Bruce just finished the 500' of bank repair on Cache Creek.

Do you want to hear more about how to build bank protection at 1/3 the cost $$ - compared to riprap ?

How is bioengineering combined with rock and redirective methods to develop equivelent (to riprap) protection that is Environmentally-sensitive?

How did utilizing Environmentally-Sensitive Biotechnical techniques effect the permitting process?

See how John and Bruce worked around and ultimately protected sensitive plants.

Give us a shout if you want more info.

In the meantime, see some before and after photos of Cache Creek.

 

 

Belly River Update!!!

John is up in Southern Canadian Rockies helping to fix up the Belly River and protect an Alberta Highway.

See photos and note the difference!!  Today he instructed Brush Layering with Soil Flaps (700 g/m2 coir netting), Pole Planting, Fiber Roll installation using "stake and rope method", and much more. 

John reports that this is the "windiest" region in Canada with the Chinooks wailing out of the Rockies.  There are reported 3000 wind generators in region.  Home of the Blood Tribe, largest first nation band in Canada - several members joined the workshop too.
