With direct access to over 1,100 miles of waterways leading to the San Francisco Bay, this is boating at its best. Ask about the boat for sale. Inside, a marble style ceramic floor in the foyer opens to a light-filled open floorplan with soaring ceilings. The kitchen shines with stainless steel appliances and abundant cabinetry, while the great room delivers an immersive entertainment experience with a professional-grade 11.1 channel Dolby Atmos surround sound system (available for purchase). The downstairs primary suite (~725 sq ft) offers a private retreat, complemented by a formal dining room and a versatile bonus room (potential 4th bedroom). Step outside to a large deck framed by lush landscaping—perfect for waterfront entertaining. The oversized 4-car shop-style garage (~930 sq ft, ~29’ x 32’) with 10’6” ceilings and a 10’ x 10’ RV door is ideal for boats, vehicles, or hobbies, plus side yard trailer storage. A rare opportunity to own a true Delta waterfront entertainer’s dream.
