The area of the ex-Shek O Quarry site is about 34.5 hectares (ha), including 22 ha of land (mostly man-made slopes) and 12.5 ha of man-made lake (site boundary at Plan 1 in Annex). The Quarry operation ceased in 2011 and the site has been used as a casting basin of immersed tube tunnel units for the Shatin to Central Link railway project since end-2014. The relevant immersed tube project has been completed. Upon the demolition, removal and reinstatement of the site, the relevant land is expected to be handed over to the Lands Department by end-2019. The site is zoned "Undetermined" on the approved Tai Tam and Shek O Outline Zoning Plan, and the Government will review the long-term use of the site in due course. Pending the formulation of the long-term use, the Government has earlier received a short-term tenancy application for the use of the ex-Shek O Quarry site for water sports purposes. The Lands Department is processing the application in accordance with the established mechanism.
