[1] In December 1903, a legislative council member, Gershom Stewart, suggested that the typhoon shelter be expanded.

The motion was passed but expansion works could not be carried out due to lack of capital.

[2] On 18 September 1906, a typhoon struck Hong Kong, destroying 3,653 boats and killing 15,000 people, most of them fishermen.

[3] In March 1908, the Government finally carried out expansion works on the typhoon shelter, deepening it by 3 metres (9 feet) and expanded it to 30 hectares (75 acres).

[6][7][8] A 2005 government report singled out the Causeway Bay Typhoon Shelter as having "exceptionally high levels" of tributyltin, exceeding 1000 times the baseline concentration measured in the East Lamma Channel.
