Oak protection countywide
The county's oak ordinance covers every species of oak beginning at a modest trunk size — removing even a relatively small oak requires county review, and larger heritage specimens trigger stricter replacement requirements.
California county profile
El Dorado spans Sierra foothills oak country and the Tahoe Basin, and the rules governing a project shift dramatically depending on which side of the ridgeline the parcel sits.
The county's oak ordinance covers every species of oak beginning at a modest trunk size — removing even a relatively small oak requires county review, and larger heritage specimens trigger stricter replacement requirements.
Parcels in the eastern part of the county that fall within the Tahoe Basin need approval from the Tahoe Regional Planning Agency in addition to county permits — a separate agency with its own review calendar, design standards, and environmental thresholds.
Essentially the entire unincorporated county falls within the state fire hazard zone, so fire-resistant construction and defensible space requirements apply to nearly every project, including additions to existing homes and accessory structures.
Which water quality agency governs your project depends on whether it sits in the Tahoe Basin or the western foothills — the standards differ meaningfully, and misidentifying your jurisdiction early in planning can require a significant redesign.
