KUALA LUMPUR: Flood risk has become a key factor in the technical assessment process for all new housing projects nationwide.
Deputy Prime Minister Datuk Seri Fadillah Yusof stated this measure ensures buyers do not become victims of developments in flood-prone areas.
He confirmed all development applications submitted through the One Stop Centre must undergo comprehensive evaluation by technical agencies.
These evaluations include assessments by the Department of Irrigation and Drainage to ensure drainage and flood mitigation aspects are considered.
Approval is only granted after these flood risk factors have been properly addressed.
“This assessment refers to the Flood Mitigation Master Plan and Annual Flood Report,“ Fadillah said during Dewan Rakyat question time.
He explained this ensures local infrastructure can cope with climate change impacts like increased rainfall and rising sea levels.
Fadillah was responding to Datuk Muhammad Bakhtiar Wan Chik from Balik Pulau regarding housing project flood risk status.
He further noted development control considers the State Structure Plan and Local Plan policies.
These plans outline land-use suitability and identify flood-risk zones across Malaysia.
For new projects, he said that the drainage system designs must comply with the Manual for Environmental-Friendly Drainage (MSMA), which emphasises an integrated rainwater management approach, such as 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,” he said.
Fadillah said the improvement of drainage systems in old residential areas would require action from various parties, including state governments and local authorities (PBTs), to evaluate and upgrade the capacity of existing systems.
In addition, he said the 41st meeting of the National Physical Planning Council (MPFN) on April 17, 2023, had agreed that the Environmentally-Friendly Drainage Master Plan (PISMA) would be adopted by all state governments and PBTs 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 added.
Replying to a supplementary question from Muhammad Bakhtiar on the status of Phase 2 of the Flood Forecasting and Warning Programme (PRAB), Fadillah said that a total of 38 major river basins are currently being monitored to strengthen early warnings and protect high-risk residential areas.
Fadillah added that the programme is implemented by the DID under the National Forecasting and Warning System, which can forecast floods up to seven days in advance and issue warnings two days before floods occur.
“The PRAB involves major river basins nationwide, developed in three phases between 2015 and 2030. Phase 1, involving Sungai Kelantan, Terengganu and Pahang, is already operational; Phase 2, involving 33 basins in the Peninsula and five in Sabah and Sarawak, is expected to be completed in 2028,” he said, adding that Phase 3 will comprise 33 basins in Sabah and Sarawak between 2025 and 2030.
So far, he said 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 a supplementary question from Datuk Abdul Khalib Abdullah (PN-Rompin) regarding 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. – Bernama
