  1. Bioengineering & “Funnel” Strategy Workshop @ Nichols Road Bridge, Onondaga Creek, NY A completed project needed some “tweaking” and veg. Top bank stone was removed the week before. All stone placement & planting occurred on Tuesday May 15, 2007.

  2. THE LAYOUT & THE PLAN Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  3. Looking US Flow

  4. Blue lines denote water’s edge at base flow bar Nichol Road Bridge Sketch from Mark Schaub

  5. Top layer of stone will be removed from red areas. The US section of the left bank will then be sloped & all areas planted.

  6. Removed stone will be then placed in the brown areas using the trenchfill technology to provide a “funnel” effect to prevent the stream from flanking the existing project.

  7. 100 Black Willow, 2,000 Streamco Willow, 500 Red Osier Dogwood & 100 Sycamore were planted using the Slit Trench & Slit Brush Layering bioengineering methods. 40 RPM container plants (7 species of trees & shrubs) were planted in the green oval areas. Black Willow & Sycamore Extreme Instant Shade shown by the orange lines. Note: Plantings form a grid to flow

  12. TWO-STAGE SLIT TRENCH TECHNIQUE Spoil Dig the trench down into the capillary (vadose) zone {moist area above the permanent water table} Sketches by Derrick Mini-Case study: 1 of 16

  13. Rubber tired backhoe digs 4-5 ft deep trench with a narrow bucket.Pix by Bill Frederick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007 Mini-Case study: 2 of 16

  14. TWO-STAGE SLIT TRENCH TECHNIQUE Water table Mini-Case study: 3 of 16

  15. TWO-STAGE SLIT TRENCH TECHNIQUE Vadose zone {moist area} is shown in pink Water table Mini-Case study: 4 of 16

  16. TWO-STAGE SLIT TRENCH TECHNIQUE Take the last scoop of soil dug from the trench & place it back into the trench. Mini-Case study: 5 of 16

  17. Rubber tired backhoe digs trench (narrow bucket). Pix by Derrick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007 Mini-Case study: 6 of 16

  18. TWO-STAGE SLIT TRENCH TECHNIQUE Place willows & other water-loving species into loose soil at bottom of trench. They are then less likely to fall over when trench is backfilled. Mini-Case study: 7 of 16

  19. Many hands get things done quickly, 2,740 plants planted in about 6 hours. That’s why they call it a workshop. Pix by Derrick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  20. TWO-STAGE SLIT TRENCH TECHNIQUE Partially backfill the trench. Mini-Case study: 9 of 16

  21. TWO-STAGE SLIT TRENCH TECHNIQUE Plant other species that require less water than the willow. In this case Sycamore & Red Osier Dogwood Mini-Case study: 11 of 16

  22. Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007 Partially backfill, then plant species that require less water (Red Osier Dogwood & Sycamore). Pix by Derrick Mini-Case study: 10 of 16

  23. TWO-STAGE SLIT TRENCH TECHNIQUE DONE Completely backfill trench & water plants in Mini-Case study: 13 of 16

  24. Backfill using either the bulldozer…..Pix by Derrick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007 Mini-Case study: 14 of 16

  29. LET’S SEE HOW IT GROWS Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  30. BEFORE 5-15-2007 8:00am. Pix by Derrick Onondaga Creek @ Nichol Road Bridge, LaFayette, NY – project planted 5-15-2007

  31. Black Willow, Streamco Willow, Red Osier Dogwood & Sycamore were planted using the Slit Trench bioengineering method. 40 RPM container plants (7 species of trees & shrubs) were planted in the green oval areas. Plantings form a grid to flow. No matter how water flows through the project, it encounters rows of vegetation (Living Dikes)
