CISEC EXAMPREP CERTIFICATION
EVALUATION EXAM QUESTIONS AND
ANSWERS 2026
◉ Rock check structures: Purpose + Requirements
Answer: For concentrated flows:
Slows down runoff to allow for deposition
Captures suspended particles along the way
Erosion control IF spaced properly
Must have a low point (for overflows) and end points must be higher
than overflow ("Smile")
◉ Check structures as an EC measure
Answer: Top of the DS structure must be in-line with the bottom of
the US structure to minimize erosion
◉ Inspecting inlet barriers
Answer: Look for debris on top of inlet barrier (indicates overflow
occurred)
Look for sedimentation behind the barrier (lack of sedimentation
entirely or uniformly indicates a failure to block at that location)
, ◉ On grade conditions
Answer: When runoff is diverted AWAY from drain inlet
◉ Inspecting curb and gutter barrier bags
Answer: Are appropriate sized rocks used in bags?
Is there overflow around the bag or underneath?
Is the bag too full/compact? Possible tearing?
Is there proper spacing between bag and inlet?
◉ Sediment Containment Systems (SCS)
Answer: Purpose: Contain runoff long enough for deposition of
suspended particles
Must properly trap and contain waters and embankments must be
stabilized against erosion
◉ Types of drainage methods
Answer: Filter bag
Riser pipe outlet structure
Skimmer outlets
◉ Filter Bag
Answer: Needs replacement when full
