- "Richmond is located on a floodplain. A ‘floodplain’ is: 'land adjacent to a watercourse that is susceptible to flooding', such as from periods of high tide. In addition, isolated instances of flooding can occur in any community as a result of unanticipated weather events. To protect Richmond from the possibility of flooding due to high tides or river floods, the City has constructed a comprehensive system of dykes on Lulu Island. These dykes are over 49 km in length and protect an area of 12,805 ha."
