KUALA LUMPUR, Oct 22 — Flood risk has now been made one of the key factors in the technical assessment process for all new housing projects nationwide to ensure that buyers do not become victims of developments in flood-prone areas, said Deputy Prime Minister Datuk Seri Fadillah Yusof.
All development applications submitted through the One Stop Centre (OSC) must undergo a comprehensive evaluation by technical agencies, including the Irrigation and Drainage Department (DID), to ensure that drainage and flood mitigation measures are considered before approval is granted.
“This assessment refers to the Flood Mitigation Master Plan and Annual Flood Report to ensure that local infrastructure can cope with the impact of climate change, which has led to increased rainfall intensity and rising sea levels,” he said during the question time in the Dewan Rakyat today.
Fadillah, who is also the Energy Transition and Water Transformation Minister, was responding to Balik Pulau MP Datuk Muhammad Bakhtiar Wan Chik's query on the flood risk status of housing projects so that buyers do not end up purchasing homes in flood-prone areas in the future.
He added that development control also takes into account the State Structure Plan (RSN) and Local Plan (RT), which outline policies and land-use suitability, including the identification of flood-risk zones.
For new projects, drainage system designs must comply with the Manual for Environmental-Friendly Drainage (MSMA), which emphasises an integrated rainwater management approach, including retention ponds and eco-friendly elements, to reduce the risk of flash floods.
"However, for older housing developments before the enforcement of MSMA, most areas lack adequate flood control systems and are more exposed to risks whenever there is unusually heavy rainfall,” Fadillah said.
Improving drainage systems in old residential areas will require action from various parties, including state governments and the local authorities, to evaluate and upgrade the capacity of existing systems.
In addition, the 41st meeting of the National Physical Planning Council (MPFN) on April 17, 2023, had agreed that all state governments and local authorities would adopt the Environmentally-Friendly Drainage Master Plan (Pisma) as a guide for the planning and implementation of more systematic and sustainable land development projects.
“Pisma serves as a reference for upgrading and building drainage systems and for planning future developments in a more structured way to reduce flash flood risks and control pollution caused by development,” he said.
Replying to Bakhtiar's supplementary query on the status of Phase Two of the Flood Forecasting and Warning Programme (PRAB), Fadillah said 38 major river basins are currently being monitored to strengthen early warnings and protect high-risk residential areas.
The programme is implemented by the DID under the National Forecasting and Warning System, which can forecast floods up to 7 days in advance and issue warnings two days before they occur.
"The PRAB involves major river basins nationwide, developed in three phases between 2015 and 2030. Phase One, involving Sungai Kelantan, Terengganu, and Pahang, is already operational; Phase Two, involving 33 basins in the Peninsula and five in Sabah and Sarawak, is expected to be completed in 2028,” Fadillah said.
He noted that Phase Three will comprise 33 basins in Sabah and Sarawak between 2025 and 2030.
So far, the PRAB monitors 1,798 hydrology telemetry stations, 614 flood warning systems, and 197 monitoring cameras operating around the clock in flood hotspots, with 3,683 high-risk locations identified.
Replying to Rompin MP Datuk Abdul Khalib Abdullah's supplementary query on the proposal to create an integrated flood risk map data portal for each housing project, Fadillah said that historical flood data, risk areas, and technical development information have been channelled to the OSC and state technical committees.
"This data can be referred to by buyers or developers to know about the status of an area, while the DID is expanding collaboration with state governments to ensure development planning takes into consideration flood risks and appropriate mitigation measures,” he said.
