CEDD Enhances Landslide Safety Management Following Ombudsman Commendation and Recommendations

CEDD commended by Ombudsman on slope safety work

Regarding the report on the direct investigation into the Government's work on landslide prevention and mitigation and management of government slopes released by the Office of the Ombudsman today (January 8), the Civil Engineering and Development Department (CEDD) welcomed the Office's high commendation and recognition of the department's efforts in implementing the Landslip Prevention and Mitigation Programme (LPMitP) and regulating slope safety. The CEDD accepts the Office's recommendations and will fully implement various initiatives while continuously reviewing their effectiveness. In response to the Office's recommendations, the CEDD will continue to strengthen its overall capability in responding to landslide risks in four areas, namely preparedness, early warning, emergency response and recovery, to keep enhancing slope safety.

On preparedness, applying a risk-based approach under the LPMitP, the CEDD systematically selects government man-made slopes for upgrading works and natural hillside catchments for mitigation measures annually. Starting from 2025, the CEDD has been progressively increasing the annual targets under the LPMitP and optimising the slope selection mechanism to strengthen resilience of slopes to heavy rain. The CEDD will review the LPMitP's targets and effectiveness in response to environmental changes, ensuring the LPMitP's continued efficacy.

The CEDD plans to fully roll out the Smart Slope Catalogue this year, integrating records of mitigation works, maintenance, rainfall endured, and landslides to expand comprehensive monitoring and data management related to slopes. By applying artificial intelligence for big data analysis, the catalogue will improve the functionality and efficiency of slope safety management, thereby better preparing for extreme weather.

On early warning, the CEDD will fully commission the AI Landslip Warning System in the wet season of this year. The system integrates Hong Kong's rainfall data and information in the Smart Slope Catalogue, and applies machine learning and big data analytics, to boost the accuracy of the predicted number of landslides during heavy rain, thereby enhancing the capability for landslide risk assessment and improving the reliability of the issuance of Landslip Warning.

On emergency response and recovery, the CEDD will stay abreast of the technological advancements in slope safety, and developing and introducing innovative technologies. This includes piloting applications of a smart unmanned drone management system on slope monitoring and emergency management to expand data collection and analytics capabilities. The CEDD will also continue to strengthen collaboration with relevant departments, such as sharing on common maintenance issues and assessment of the impact of heavy rain on slopes, with a view to enhancing slope safety and reducing landslide risk.

The Office noted that the landslide incident rate for government slopes is relatively higher and that there are cases of repeated occurrences. In fact, this is mainly related to the categorisation of slopes and their potential impact, reflecting the government's risk-based approach to slope management. The man-made slopes maintained by the government are distributed over an extensive area, possess diversified nature, and have different levels of risks. These include slopes with relatively high, medium, and relatively low potential impacts, categorised mainly by the risk of loss of life in the event of a landslide. To ensure public safety, the government will prioritise landslide prevention works on slopes that pose a higher potential impact. Some of the government slopes that fall into medium or relatively low potential impact categories may not be accorded priority because of their relatively remote locations or a lower risk of loss of life. As such, those government slopes with medium and relatively low potential impacts may also experience landslides under a risk-controlled condition. On the contrary, private man-made slopes are more similar in nature. Most of them are close to private residences and would pose greater impact on the residents in the event of a landslide. They are generally categorised as having relatively high potential impact and receive a higher level of attention. This explains why the overall landslide incident rate for government slopes appears higher, and why landslides may occur repeatedly on some individual slopes with medium or relatively low potential impacts.

In fact, between 2020 and 2024, the annual landslide incident rates for both government and private man-made slopes remained below one per cent (ranging from 0.1 per cent to 0.6 per cent for government slopes and 0.03 per cent to 0.3 per cent for private slopes), which is a very low level. Overall, an average of about 214 incidents were recorded annually over the past decade (2015 to 2024), representing a decrease of nearly one-third compared to the average of about 300 incidents between 1989 and 2014. This reflects the notable results achieved through the ongoing prevention and mitigation efforts.

In response to the landslide incidents triggered by the extreme rainstorm in September 2023, the CEDD has completed a systematic review and study, putting forward a number of recommendations to optimise the LPMitP. New measures include expediting the progress of LPMitP and prioritising, under a risk-based approach, the risk management of man-made slopes located along sole vehicular accesses and those with a greater potential impact on the public's daily lives. The CEDD thanks the Ombudsman for recognising in its report the department's timely review and adjustment of the direction of the LPMitP, acknowledging that such an approach is proactive and effective in adapting to changing circumstances.

The CEDD will continue to closely monitor slope safety in Hong Kong and remains committed to enhancing slope safety management through collaboration, driving Hong Kong's development as a resilient and livable world-class city.

Collecting preferences of Wang Fuk Court flat owners to advance long-term rehousing work

A Government spokesman said today (January 9) that social workers under the "one social worker per household" service of the Social Welfare Department (SWD) are proactively contacting flat owners of Wang Fuk Court, who were affected by the fire. They are comprehensively and systematically gathering each owner's preliminary preferences regarding long-term rehousing to assist in formulating and implementing specific plans.

The Chief Executive previously instructed the Task Force on Emergency Accommodation Arrangements to co-ordinate relevant policy bureaux and departments in studying long-term rehousing solutions. Adhering to the principles of "empathy, reason, and law", with priority given to "empathy", the Task Force aims to address the individual circumstances and preferences of residents while ensuring the efficient use of resources to assist affected households in rebuilding their homes.

The spokesman said, "Social workers from the SWD have been in contact with the residents, listening to their views, understanding their actual situations and needs, and providing necessary assistance. Regarding long-term accommodation, we have noticed differing opinions among flat owners and the community. For example, some hope that the Government will acquire the properties or give priority to Wang Fuk Court flat owners to purchase Home Ownership Scheme flats. Some residents seek local rehousing, while others accept rehousing in different districts. Some propose in-situ redevelopment, but there are also concerns about the lengthy waiting times.

"We hope to systematically and comprehensively collect Wang Fuk Court flat owners' opinions, further listening to and summarising their preferences. This includes identifying key principles that the Government should consider when addressing long-term accommodation arrangements and noting the flat owners’ initial preferences for different long-term rehousing options. This information will serve as a reference for the Government's follow-up actions."

Starting today, social workers under the SWD's "one social worker per household" service will begin contacting flat owners of Wang Fuk Court to gather their initial preferences regarding various long-term rehousing arrangements. The goal is to collect responses from the flat owners by mid-to-late January for analysis.

The spokesman said, "The Task Force will carefully compile and study the different preferences of flat owners and will conduct a comprehensive assessment based on the actual conditions at Wang Fuk Court, including structural safety, technical feasibility, and community planning. We aim to provide affected flat owners with suggestions regarding long-term proposals as soon as possible for their consideration and decision-making."

He said, "The Government and affected flat owners share a same objective: to implement solutions promptly and reassure them as soon as possible."

Following the fire, the Government arranged emergency accommodation for the affected residents of Wang Fuk Court in a short time frame. As of today, more than 4 400 residents are staying in hotels, youth hostels/camps, transitional housing, units from the Hong Kong Housing Society or Po Tin Interim Housing in Tuen Mun. Since December 22 last year, the Support Fund for Wang Fuk Court in Tai Po has provided each flat owner, in tranches, with a two-year rental subsidy up to a maximum of $300,000, giving them more flexibility and options in their accommodation arrangements.
