Sea Island is the home to YVR and a charming, residential area of Richmond named Burkeville. Sea Island Real Estate is exclusively found in the neighbourhood of Burkeville, a community established during World War II to house workers in the Boeing aircraft plant and other local aircraft industries located on Sea Island. Students from Burkeville attend Sea Island Primary, Brighouse Elementary and Richmond Secondary.
One of the larger islands that make up the City of Richmond, Sea Island is in the estuary of the Fraser River and offers two public beaches. McDonald Beach, located on the northern end of the island, is a recreational facility, with picnic areas and boat docking available. Iona Beach features a walking trail into the Sturgeon Bank, information on the flora and fauna and allows a natural rather than recreational environment to be enjoyed.
