Erosion Control
CSI Division 31, Earthwork
Temporary measures, silt fence, inlet protection, sediment basins, installed to keep disturbed soil from washing off a construction site into storm drains, streams, or neighboring properties, typically required by a site's Stormwater Pollution Prevention Plan (SWPPP) under federal and state stormwater regulations.
Why it matters
Sediment leaving a construction site isn't just a housekeeping issue: it's a regulated environmental discharge, and a project that lets erosion control measures fail can face real regulatory fines from the EPA or a state environmental agency, not just a cleanup bill.
On a real project
A site installs silt fence along its downhill perimeter and inlet protection at every nearby storm drain before any significant earthwork begins, inspecting and maintaining those measures throughout construction as the SWPPP requires.
Who this matters most to
A Construction Laborer installs and maintains erosion control measures like silt fence throughout the project, work that has to continue as long as soil stays disturbed. An Environmental/Remediation Specialist oversees SWPPP compliance and documents the required periodic inspections that regulators can request at any time.
Where this goes wrong
A site's silt fence is installed correctly at the start of a project but never inspected or repaired after a storm damages a section of it. Sediment washes through the gap into a storm drain during a later rain event, and a state inspector cites the project for a stormwater violation that a routine inspection would have caught before it became a discharge.
