RACKET CREEK NEAR INDEPENDENCE, KANSAS
Bank erosion is actively eroding and threatening infrastructure within a U. S. Army Corps of Engineers public campground
Rural, sparsely populated Bed material: silts, clay, aluvium, deeply incised Pool-riffle-pool regime, slope less than 1% Average width 30-40 ft 32 ft tall eroding banks are a public safety issue One gully had a series of headcuts up to 4 ft tall.

Willow poles (termed Live Siltation) were then laid on the LPSTP at a rate of 3.5 poles per ft. Basal

Soil dug from the opposite bank of the stream was used to “plant” the Live Siltation & also to
provide a flatter slope for the eroded bank.

Root Production Method (RPM) cRaZy gRoWtH WITHOUT CHANGING GENETICS
(for oaks 0.8 inches @ DBH/year and 4 ft of growth per year are typical
A patented process RPM Method developed by Wayne Lovelace in 1991 Wayne Lovelace has 50 years experience in horticulture RPM Method applied to over 250 different species-trees,
shrubs, & grasses Cost effective – 50 trees per acre vs 300-400 with seedlings 60 acres of planted Mississippi River hardwood floodplain
we observed (50 trees/acre, total 3,000 trees), only 7 trees dead

The RPM method is a 21 step patented process, with plants
grown in bottomless trays. The tap root hits air and stops
growing (air pruned). Plant is repotted twice, mychorrhiza inoculated twice, the rest is
secret !!

Acorns growing on a 6 month old Burr Oak. Typically these trees do not produce acorns during the first 30 years. Wayne says acorn
production coincides with the wasting away of the tap root.

“Kimberley”, a natural cross between a Swamp White Oak & a Burr Oak discovered by Wayne’s wife. Over the last 20 years it has delivered 100 lbs of
acorns per year (not diurnal). 50 Kimberlys per acre=5,000 lbs seed/food.

Stream Project Functions:
Fully functioning both hydraulically & environmentally. Multiple protection redundancy. Longitudinal Peaked Stone Toe Protection provides a robust adjustable bank toe protection. Bendway Weirs move scour & thalweg away from attacked bank, with velocities reduced within weir field & on bank. Live Siltation, pole plantings, & rooted-stock plants provide roughness & reduce near-bank flow velocities. Roots strengthen bank & bind soil. Bank & top bank rooted stock plantings will provide stability and a continuous riparian corridor.
