Exceptional Development Opportunity at Westwood Hills Discover a rare opportunity to create four executive estates in one of Napa's most desirable locations. This 4+ acre parcel, situated on the east side of Westwood Hills at 155 Riordan Lane, offers sweeping views of Downtown Napa, the surrounding eastern hills, and the picturesque valley beyond. The property is being offered with a lot line adjustment at close of escrow, with the intent to create four approximately one-acre residential lots. The seller will retain a portion of the property as part of the lot split. The lot line adjustment will take place at the final map stage. With city services available on the property and an exceptional location just minutes from downtown Napa, shopping, dining, and world-class wineries, this property presents an outstanding opportunity for developers, builders, or those seeking to create a private enclave of luxury custom homes. Bring your vision and capitalize on the scarcity of large residential parcels in this sought-after neighborhood. Panoramic views, generous homesites, and close proximity to urban conveniences combine to make this a truly one-of-a-kind offering.
