1 WHAT EVERY LANDFILL OPERATOR NEEDS TO KNOW ABOUT EROSION CONTROL

2 ESTABLISHING VEGETATION SEED MULCH THE BASICS SEED BED PROTECTION TURF REINFORCEMENT SOIL TEST!

3 SEED SELECTION CHOOSE SEED APPROPRIATE FOR SOILS, CLIMATE AND SPECIFIC SITE NEEDS SEEK ADVICE FROM QUALIFIED SOURCES

4 MULCH MULCHES CONTROL WEEDS. MULCHES CUT DOWN ON EVAPORATION FROM THE SOIL. MULCHES KEEP SOIL WARMER IN THE AUTUMN AND COOLER IN THE SUMMER. MULCHES PREVENT SOIL EROSION. MULCHES CONTROL DISEASES. David Robson, University of Illinois Extension

5 VEGETATION ESTABLISHMENT BARE GROUND SEEDING LOOSE MULCH CRIMPED MULCH HYDROMULCH BONDED FIBER MATRIX EROSION CONTROL BLANKETS TURF REINFORCEMENT MATS

6 BARE GROUND SEEDING VERY INEXPENSIVE VERY RISKY FAILURE CAN LEAD TO COSTLY REMOBILIZATION PARTICULARLY VULNERABLE ON SLOPING AREAS, CONCENTRATED FLOW AREAS AND ALONG SHORELINES

7 MULCHES LOOSE MULCH CRIMPED MULCH PROVIDE SEED PROTECTION AND ENHANCE VEGETATIVE GROWTH VULNERABLE TO EROSION SAME POSITIVE CHARACTERISTICS AS LOOSE MULCH MUCH LESS VULNERABLE TO EROSION THAN LOOSE MULCHES

8 HYDROMULCHES HYDROSEEDING SEED AND WATER HYDROMULCHING SEED, WATER, MULCH BONDED FIBER MATRIX SEED WATER MULCH AND TACKIFIER FLEXIBLE GROWTH MEDIUMS

9 HYDROMULCHES HIGH PERFORMANCE HYDROMULCH CONTINUING TO EVOLVE

10 EROSION CONTROL BLANKETS TEMPORARY PRODUCTS PROTECT SEED AND DEGRADE AS VEGETATION BECOMES ESTABLISHED PROVIDE UNIFORM COVERAGE

11 The Traditional Range of Techniques offers limited options. Erosion Control Blankets opened a new window.

12 BLANKET TYPES ONE GROWING SEASON (STRAW OR WOOD FIBER) TWO GROWING SEASONS (STRAW/COCONUT) THREE GROWING SEASONS (COCONUT)

13 BLANKET NETTING OPTIONS CLEAR PLASTIC GREEN PLASTIC JUTE/ORGANIC BLACK PLASTIC

14 NETTING CHARACTERISTICS CLEAR PHOTODEGRADABLE WILL BREAK DOWN IN DAYS GREEN SLOWER DEGRADING CAN TAKE 1-2 YEARS TO BREAK DOWN GREEN NETTED PRODUCTS SHOULD NEVER BE USED IN AREAS THAT WILL BE MOWED!

16 SLOPES

17 CHANNELS

18 OTHER CHANNEL OPTIONS

19 TURF REINFORCEMENT MATS PERMANENT REINFORCMENT OF THE ROOT AND STEM STRUCTURE OF THE VEGETATION ABOUT 1/3 THE COST OF RIPRAP

20 TURF REINFORCEMENT MATS VS. RIPRAP ATTRACTIVE APPEARANCE LOWER COST SAFETY SEDIMENT & POLLUTANT FILTRATION LOWER MAINTENANCE COSTS

21 SHEAR STRESS CAN BE DESCRIBED AS THE PULLING OR TEARING ACTION CAUSED BY CONCENTRATED FLOWS SHEAR STRESS TOLERANCE (LBS/FT) BARE SOIL 0.0 SOD 1.0 STRAW EC BLANKET 1.55 ESTABLISHED TURF 2.7 TRM 10.0 TRM 12.0 TRM 14.0

26 RESULTS RIP RAP ESTIMATED INSTALLED COST WAS $2,000,000 INSTALLATION OF TURF REINFORCEMENT MAT COST $400,000

27 BOTTOM LINE PROJECT RESULTED IN A NEW TURF REINFORCEMENT MAT SPECIFICATION FOR THE ILLINOIS DOT!

28 CASE STUDY #2 The Links at Ireland Grove BLOOMINGTON, ILLINOIS NEW GOLF COURSE CONSTRUCTION FOUR PONDS

29 SUPERINTENDENT S WISH LIST NATURAL VEGETATION ALONG SHORELINE NO ROCK! PONDS ARE CENTERPIECE OF COURSE MAKE THEM LOOK NATURAL

42 QUESTIONS (TRUE OR FALSE) 1. SOIL TESTING IS EXPENSIVE AND SHOULD BE AVOIDED. 2. MULCH IS AN ESSENTIAL COMPONENT OF MOST TEMPORARY EROSION CONTROL PRODUCTS. 3. TURF REINFORCEMENT MATS DO NOT INCREASE THE SHEAR STRESS TOLERANCE OF TURF. 4. GABION WALLS CANNOT BE VEGETATED. 5. CELLULAR CONFINEMENT PANELS CAN HELP STABILIZE VERY STEEP SLOPES.
