Key Takeaways
- On 6 November 2026 the Selangor State Executive Council ordered an immediate halt to all development works in Puncak Alam, Kuala Selangor, while flood mitigation plans and the Environmental Impact Assessment (EIA) are reassessed.
- The order followed a week of flash floods. On 5 November, rain of 102 to 103 mm around the UiTM Puncak Alam campus sent water into Hillpark, Seri Alam and Saujana Perdana and affected more than 1,000 homes.
- Menteri Besar Datuk Seri Amirudin Shari will also order a review of approved development projects, including a requirement for developers to build temporary water retention facilities.
- Two projects near Saujana Aman, of 15 acres and 5 acres, will be inspected after being identified as adding to the overflow.
- No end date, project list or exemption has been published. Puncak Alam is home to industrial parks such as Eco Business Park V, so anyone buying, building or fitting out a factory there should check their own site now.
What Selangor Decided
The decision was made at the state executive council meeting and announced by the Menteri Besar in a statement on Friday, 6 November. The Star reported that all development projects in Puncak Alam will be halted "to facilitate flood mitigation efforts and allow for reassessment of their environmental impact". The Bernama report carried by Malay Mail says the council decided "to immediately halt all development works in Puncak Alam, Kuala Selangor, while flood mitigation plans and the Environmental Impact Assessment are reassessed". FMT carried the same statement.
The same statement also said:
- Jalan Batu Arang in Rawang will be temporarily closed by the Public Works Department (JKR) to repair a collapsed slope.
- Small and large flood mitigation works across the state, especially in high-risk areas, must be expedited rather than follow conventional schedules, because rain is expected almost daily.
- The Drainage and Irrigation Department (JPS) will speed up repairs to affected drains and carry out urgent water diversion works.
- Aid of up to RM1,500 from the National Disaster Management Agency (Nadma) and the state government will go to victims at temporary relief centres.
Earlier the same day, after inspecting a retention pond at the UiTM Puncak Alam campus, Amirudin said the state would look again at approvals already granted. "I will request a review of all approvals we have granted, including imposing a requirement for developers to construct temporary water retention facilities; we certainly do not want them to carry out the work in a shoddy or substandard manner," he said, as reported by Malay Mail.
Why Puncak Alam Flooded
Several areas of Selangor were hit by thunderstorms during the week, and flash floods displaced dozens of families in Kampung Melayu Subang, The Star reported. In Puncak Alam, the Menteri Besar said the flood on 5 November came from unusually heavy rain of 102 to 103 mm on the high ground around the UiTM campus. The runoff spilled into Hillpark, Seri Alam and Saujana Perdana and affected more than 1,000 homes, Harian Metro reported.
Two development projects near Saujana Aman, covering 2.02 hectares and 6.07 hectares (about 20 acres in total), were identified as adding to the overflow and will be inspected. Amirudin said overflow would have happened even without them, but their presence made it worse.
Elsewhere, the state found that embankments of the Sungai Buloh 1 Flood Mitigation Scheme (RTB) had been lowered below their original specifications by vandalism, and that water was overflowing from the West Coast Expressway (WCE). Action will be taken against illegal operations, with demolitions at two identified locations so the sites can be gazetted as water catchment areas or floodplains.
Why It Matters for Factories in Puncak Alam
Puncak Alam is not only a housing town. It holds several industrial parks, including EcoWorld's Eco Business Park V off the Guthrie Corridor Expressway (GCE) and LATAR, Taman Industri Alam Jaya and Alam Perdana Industrial Park. Eco Business Park in Puncak Alam is also one of the sites named for Google's planned data centre campuses, as covered in our Google data centre report.
The industrial market here is active. In the JPPH-registered transactions for Ijok and Puncak Alam, 22 industrial deals worth RM126.39 million were recorded in the 12 months to August 2026, and Eco Perindustrian V (the registered name of Eco Business Park V) was the most active park, with 26 deals in 24 months. Over 24 months, semi-detached factories had a median price of RM3.3 million (RM225 psf of land), detached factories RM7.5 million (RM192 psf of land) and industrial land RM90 psf of land. Registered factory tenancies had a median rent of RM1.52 psf/month.
The statement covers "all development works in Puncak Alam". It does not list projects, it does not mention industrial parks or any exemption, and it gives no end date. Until the state or the Kuala Selangor Municipal Council (MPKS) says more, assume that construction, earthworks or major building works anywhere in Puncak Alam may be affected, and confirm the position for your own site.
What It Means for Buyers, Tenants and Owners
If you bought a factory that is still being built
Write to your developer and ask whether your phase has been told to stop, and what the revised delivery date is. Factories are generally not sold under the statutory sale agreements of the Housing Development Act, so your protection depends on your own sale and purchase agreement. Check the delivery period, the late delivery compensation clause and any clause on delays caused by government orders. If your bank loan is released by stages of work, tell your banker early: a stopped site means stopped progress billings.
If you are building on your own industrial land
Ask your consultant whether your approved building plan or earthworks permit falls under the review. The Menteri Besar has said developers may have to build temporary water retention facilities, so expect questions on drainage, silt control and temporary ponds before work restarts. Allow extra time in your programme, not only extra money.
If you rent, or plan to rent, in Puncak Alam
The order is about development works and the statement says nothing about closing factories that are already operating. Fit-out, extension or new mezzanine works may still need permits, so check with MPKS before you start any building work. When you view a unit, ask the landlord directly whether the premises or the access roads took water on 4 or 5 November, and look at drain levels and loading bay heights yourself.
If you are looking at industrial land
Land in Puncak Alam still trades above the wider district: RM90 psf of land against RM64 psf for Kuala Selangor District in the registered data. Before you sign, ask how long approvals could take while the review runs, and compare the site's level with the roads and drains around it.
Beyond Puncak Alam
The halt is local, but the review of approved projects in high-risk areas is a signal for the whole state. Industrial developers in low-lying parts of Ijok, Kuala Selangor and Klang may face tighter flood conditions on approvals. The Ijok flood of 2 November, when workers were trapped at a factory in Taman Industri Batu 22, involved the same Sungai Buloh river system; see our Ijok flood report. In Klang, residents were told to prepare for a five-day high tide from Saturday, 7 November (Harian Metro).
Practical Next Steps
- Get written confirmation from your developer or contractor on whether your site is affected.
- Keep copies of your approvals and ask your consultant to check the flood mitigation conditions.
- Before renting, ask about flooding on 4 and 5 November and confirm your insurance covers flood.
- Follow official statements from the Selangor government and MPKS on the scope and end date of the halt.
