California county profile
Inyo County
Most of Inyo is federal land, and the private-land projects that remain often touch sensitive desert habitat or sit near the Owens Lake dust mitigation zone — one of the largest ongoing air quality compliance programs in the country.

What catches people off guard in Inyo County
Owens Lake dust zone
Projects near Owens Lake sit adjacent to one of the largest airborne dust compliance programs in the country; even routine earthwork in that area can intersect with dust control requirements administered jointly by the local air district and a major water utility.
Federal land everywhere
More than nearly all of the county is federal land; private projects adjacent to national parks or Bureau of Land Management areas often require federal agency review that runs on its own timeline, separate from state environmental review.
Desert plant protections
The California Desert Native Plants Act covers the plant palette here — removing cacti, Joshua trees, or other desert species may require a permit even for routine grading or landscape clearing.
Water rights overlay
The Owens Valley's water history is long and legally complex; projects that involve wells, diversions, or any water use may need to navigate state and federal water rights constraints that don't apply in most other California counties.
