What the island actually is
Built with the lake itself in the late 1960s as the master plan's centerpiece: a guarded bridge, interior lanes, and lots oriented to the water. The culture is electric boats to lakeside dinners, paddleboards off the dock, and the only true waterfront daily life between Malibu and the marinas.
The diligence trio
- County line: confirm which side a specific address sits on — LVUSD vs CVUSD schools, LA vs Ventura assessor, and insurance markets all follow it.
- Lake/dock rights: WLMA rules govern docks, boats, and shoreline work; HOA + WLMA fees stack — model both.
- Waterfront fabric: seawalls, docks, and water-adjacent systems get their own inspections; original-1970s infrastructure prices differently than redone frontage.
