Erosion and Sediment Control Plan
Erosion and sediment control drawings for grading permits, showing silt fence, inlet protection, stabilization and phasing. Typical US fees run $500 to $8,000, and most projects take 1 to 3 weeks. Our drawings, calculations and reports are sealed by a Professional Engineer (PE) licensed in the state where your project is located, ready for permit submission.

What the work involves
Most grading and building permits that disturb soil require an erosion and sediment control plan. The engineer locates silt fence, construction entrances, inlet protection, sediment traps or basins, slope protection and stabilization measures, and phases them with grading. On sites under the 1 acre federal threshold, local ordinances often still require these plans.

Do small projects need erosion control?
Many local ordinances require erosion controls on any land disturbance, even below the federal 1 acre threshold. Check your local grading or stormwater ordinance.
What is a construction entrance?
A stabilized gravel pad that knocks mud off tires so it is not tracked onto public roads. It must be maintained and refreshed as it fills with mud.
Who inspects the controls?
Local inspectors and, on permitted sites, the operator's own inspectors per the SWPPP. Failed controls must be repaired promptly.
When can controls be removed?
After the site is permanently stabilized, typically with established vegetation or pavement. Removing them too early can lead to violations.
