Do I Need a Permit for Landscape Grading or Regrading? in Verenigde Staten
Minor grading for garden beds or leveling a small area is usually exempt from permits. However, projects that change drainage patterns across property lines, involve large volumes of fill or cut, affect stormwater runoff to neighbouring properties, or are near waterways and wetlands typically trigger grading permits. Erosion control plans may be required above certain disturbed-area thresholds.

Country-specific detail
US grading permit requirements vary widely by municipality. Many cities require a grading permit when the project involves more than 50 cubic yards of cut or fill, disturbs more than 5,000 sq ft, or changes drainage patterns affecting neighboring properties. The EPA's NPDES Construction General Permit (CGP) requires a Stormwater Pollution Prevention Plan (SWPPP) for sites disturbing one acre or more. Grading within a FEMA-designated floodplain requires both a local floodplain development permit and compliance with NFIP standards. Some jurisdictions require a grading plan prepared by a licensed civil engineer. Erosion and sediment control measures (silt fences, detention basins) are standard permit conditions.
