1 Bioengineering & “Funnel” Strategy 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 Onondaga Nichol Road Bridge, LaFayette, NY – project planted THE LAYOUT & THE PLAN

3 Looking US Flow

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

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

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

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 Onondaga Nichol Road Bridge, LaFayette, NY – project planted Rubber tired backhoe digs trench (narrow bucket). Pix by Derrick 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 Onondaga Nichol Road Bridge, LaFayette, NY – project planted 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

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 Nichol Road Bridge, LaFayette, NY – project planted 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 Completely backfill trench & water plants in Mini-Case study: 13 of 16 DONE

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

29 Onondaga Nichol Road Bridge, LaFayette, NY – project planted LET’S SEE HOW IT GROWS

30 Onondaga Nichol Road Bridge, LaFayette, NY – project planted BEFORE :00am. Pix by Derrick

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)

69 Site – soil conditions are not ideal. Fill soil is a clay fragipan, when dry is like concrete. (Extremely dry summer -2007) Slit-Trench Black Willow-low mortality & outstanding growth, many 9 to 10 ft tall. When planted most 2-3 ft tall. Slit-Trench Streamco Willow-low mortality & outstanding growth, many 9 to 14 ft tall. Slit-Trench red osier dogwood – medium mortality, very good growth Slit-Trench & Slit Brush Layering Sycamore – high mortality, few if any survived Extreme Instant Shade Sycamore – all dead. Slit Brush Layering Willow – med mortality, decent growth, not very tall. Slit Brush Layering Red Osier Dogwood – low to medium mortality- dominating with lush growth. Pole Plantings in existing stone bank – low mortality, ~6-8 ft growth. RPM rooted stock trees – outstanding shrub growth, beaver browse on several trees, mixed performance on remainder of trees, many surviving not thriving, with a couple showing fast growth, ft tall. RESULTS AFTER TWO GROWING SEASONS
