Intense rainfall over a short duration has made the exit of Jalan SS7/2 onto Jalan Lapangan Terbang Subang dangerous.
Expatriate Al-Muhainim Abdulsalam said the first flood-prone stretch is located about 130m from the Jalan SS7/2 exit.
Water rapidly accumulates during heavy rain and narrows the road into a single lane.
“Whenever it rains, water on the left side of Jalan Lapangan Terbang Subang reaches knee-level,” said Al-Muhainim, who is from Yemen.
He added that another critical point occurs about 730m further up, before the Persiaran Kewajipan ramp, where surface run-off floods the left side of the road that narrows into a single lane too.
Student Nur Damia Osman, who lives in Subang Jaya, said the recurring floods not only disrupt traffic flow but also posed safety concerns.
Residents and road users are urging the authorities to take immediate action to resolve the issue.
Engineer Lim Thiam Chai, who is familiar with the area, said the drainage system needed to be improved.
“An immediate solution is to increase water flow capacity at the affected stretches.
“I urge the authorities to carry out a detailed assessment of the drainage network and implement upgrading works as soon as possible,” he said.
In a May 5 report on the issue by StarMetro, “Fairway makes way for drain”, it was revealed that Kelab Golf Negara Subang (KGNS) had agreed to cede part of its fairway to make way for drainage and irrigation works to address flood woes in Jalan SS7/2.
Checks revealed that Petaling Jaya City Council (MBPJ) oversees part of the road closer to the Jalan SS7/2 exit while the second flood-prone area comes under the purview of Selangor Public Works Department (JKR).
An MBPJ spokesperson said drainage and irrigation works to address floods has begun along Jalan SS7/2 and was due to be completed by Nov 5.
“Works include 1.5m-wide precast U-drains, box culverts, reinforced concrete sump and roadside scupper drains.
“With these measures, the floods should be resolved.”
For the second critical flood area that comes under Selangor JKR, a spokesperson said the immediate plan was to widen the drainage to accommodate the volume of surface run-off.
