In a Facebook post, Yeoh said an urgent meeting was held this morning to address the flooding and it was attended by all relevant agencies and chaired by Kuala Lumpur mayor Fadlun Mak Ujud.

She added that several mitigation and rectification measures are underway, including increasing the capacity of the second ESCP pond and carrying out desilting and maintenance on the first ESCP pond.

Other measures being carried out include maintaining all unlined drains on site, removing collapsed structures, installing new Jersey Barriers, and flushing drainage systems.

“The Selangor public works department (JKR) has also stepped in this morning with additional machinery to expedite repair works,” Yeoh said.

The minister added that the control centre set up by City Hall (DBKL) will operate round the clock during this period.

“The development order for this project was issued on Oct 3, 2022,” she said.

Earlier today, DBKL issued a stop-work order for the project, under the purview of the national landscape department, after heavy rain damaged aluminium panels and sent mud flowing onto the nearby road, Jalan Abang Haji Openg.

DBKL also issued a compound notice to the contractor, in view of the situation and the potential safety risks to residents.

Fadlun had ordered a review of all slope development works in the Bukit Kiara Federal Park area nearby, and called for new guidelines for phased and controlled earthworks to be introduced.

JKR had been instructed to carry out a detailed technical investigation to determine the root cause of the flooding that led to the collapse of a retaining wall near the project yesterday.

The department has also been directed to assess the structural integrity of the affected area and recommend additional mitigation measures.
