The California Environmental Quality Act (CEQA), Sierra County zoning code (Title 15) and Sierra County environmental review (Title 38) may require the preparation of environmental documents concerning a proposed grading project. Supplemental studies and reports may be deemed necessary by the Planning Director due to the project site’s location on or proximity to steep slopes, unstable soils, potential wetlands, sensitive habitat, cultural resources, or other constraints. Any required environmental review must be completed before the grading permit application will be deemed complete and a permit issued.
