While the cause of the sinkholes was still being determined, residents said that they had alerted DBKL to look into flooding issues prior to the incident.
Desa Angkasa condominium building executive Sarah Bakri said that water would flood the building during heavy rain.
“The situation has only worsened since 2014,” she said when met at the site.
Sarah added that their security guards had noticed the first sinkhole around 3.30pm on Sunday and DBKL was notified.
“Two hours later we were shocked to see another sinkhole,” she said.
During a site visit, Kuala Lumpur mayor Datuk Nor Hisham Ahmad Dahlan said that long-term measures would be implemented but currently, they had to determine if there was any further ground movement.
“Based on that, we will see if there is any need to evacuate residents.
“A coordination meeting would be held soon with the other departments, utility companies and relevant agencies,” he said.
DBKL officers would also be stationed around the clock to monitor the site.
Nor Hisham said the second sinkhole appeared about two hours after the first caused a portion of the road and the outer wall of an apartment block in Taman U-Thant to cave in.
A water pipe, which had burst in the incident, had also been fixed and water supply restored to affected residents.
A portion of the road, however, remains closed.
DBKL also said that sinkholes reported at Jalan Cheras and Jalan Gombak on Sunday were being repaired.
