OUTLET PROTECTION
DEFINITION
STRUCTURALLY LINED APRONS OR OTHER ACCEPTABLE ENERGY DEVICES PLACED AT THE OUTLETS OF PIPES OR PAVED
CHANNEL SECTIONS
PURPOSE
1. TO PREVENT SCOUR AT STORMWATER OUTLETS AND TO MINIMIZE THE POTENTIAL FOR DOWNSIREAM EROSION BY
REDUCING THE VELOCITY OF CONCENTRATED STORMWATER FLOWS
EXTEND RIPRAP TO I-EIGHT OF CULVERT OR
NORMAL CHANNEL DEPTH. WHICHEVER IS SMALLER

DEFINITION
PROVIDE A ROUGH SOIL SURFACE MTN HORIZONTAL DEPRESSIONS CREATED BY OPERATING A TILLAGE OR OTHER
SUITABLE IMPLEMENT ON THE CONTOUR, OR BY LEAVING SLOPES IN A ROUGHENED CONDITION BY NOT FINE - GRADING
PURPOSES
1. TO ND IN SEED BED PREPARATION AND ESTABLISHMENT OF VEGETATIVE COVER.
2. TO REDUCE RUNOFF VELOCITY AND INCREASE INFILTRATION.

DEFINITION
APPLICATION OF PLANT RESIDUES OR OTHER SUITABLE MATERIALS TO THE SOIL SURFACE
PURPOSES
1. TO PREVENT EROSION BY PROTECTING THE SOIL SURFACE FROM RAINDROP IMPACT AND REDUCING THE VELOCITY OF
OVERLAND FLOW.
2- TO FOSTER THE GROWN OF VEGETATION BY INCREASING AVAILABLE MOISTURE AND PROVIDING INSULATION AGAINST
EXTREME HEAT AND COLD.
