To address potential flooding from Super Typhoon Ragasa, the Drainage Services Department (DSD) has implemented a number of special operational measures.
 
The DSD, the Civil Engineering & Development Department (CEDD) and the Home Affairs Department (HAD) held a joint press conference today to release the latest flood risk assessment and brief the public on the corresponding response measures.
 
According to the latest forecast by the Observatory, a storm surge of about 2m is expected on the morning of September 24, with the maximum coastal water level generally reaching around 3.5 to 4m above chart datum, and reaching as high as 4 to 5m above chart datum in Tolo Harbour.
 
The DSD has increased the number of emergency response teams to a total of 200 to handle flooding and clear drainage channels in different districts across the city, and deployed powerful pumping robots on standby in advance at multiple locations with higher risk of flooding.
 
In addition, the DSD and the CEDD have provided sandbags to the public, with more than double the usual number distributed. For coastal low-lying or windward residential areas with higher risks, the DSD and the CEDD have deployed temporary water-filled barriers at Po Yick Lane and Pak Shing Street near Kwong Fuk Bridge along the Lam Tsuen River in Tai Po. They have also set up sandbag walls along the Tseung Kwan O waterfront.
 
The DSD has been maintaining close liaison with Shenzhen Authority. At present, there is no discharge plan for the time being. Should a discharge regulation be implemented during the typhoon, Shenzhen Authority will provide timely notification.
 
Members of the public should stay vigilant about the risks brought by storm surge and overtopping waves, take defensive measures as early as possible, and avoid the affected locations as far as practicable.
 
The DSD urges the public to call the 24-hour Drainage Hotline at 2300 1110 to report blocked public drains or flooding for prompt assistance.
