declassify Klang Valley landslide 'hazard map'
20/12/2009 The Star By SARBAN SINGH
TAMPIN: With the rainy season causing fears of more landslides, the
Cabinet has decided to make public a report on a “hazard map” covering a
100 sq km area in the Klang Valley.
Works Minister Datuk Shaziman Abu Mansor said the report, which among
others identifies 216 “risky slopes” in the Ampang-Ulu Klang area, had
been submitted to Kuala Lumpur City Hall and the Ampang Jaya, Selayang and
Kajang municipal councils for remedial action.
A mudslide at Taman Jasa Utama in Batu Caves last month.
He said the area under scrutiny spanned Cheras to Taman Melawati in Ulu
“We decided to make the report public because we want the authorities to
take remedial action immediately. This is necessary to prevent further
landslides,’’ he told reporters here after presenting financial awards to
students who excelled in the UPSR exam.
The Government had commissioned the study in 2006 following a spate of
landslides in the Klang Valley, notably in the Bukit Antarabangsa area.
The study was completed in January this year.
On Dec 4, the Cabinet declassified the Bukit Antarabangsa landslide
report. The incident claimed the lives of five people in December last
year, with 14 bungalows destroyed and hundreds of residents displaced.
Shaziman said a total of 583 slopes were checked under the study.
He said the report would also allow the authorities to better plan
development in the areas concerned.

“The report is general (in nature) and done at the macro-level. But it
will be a good reference for those living in the area as well as for
developers,” he said.
Although the report was not as detailed, with global positioning system
(GPS) used to map out the areas, he said experts were able to identify
tension cracks, erosions and unstable boulders.
“For a detailed report, a thorough study on the stability of the slopes
needs to be done and these cover its geological aspects,” he said.
Shaziman also said he had received on Thursday the findings on the roof
collapse at Stadium Sultan Mizan Zainal Abidin in Gong Badak, Terengganu.
The proposed Damansara 21 hillslope project in Medan Damansara.
“Ten independent investigators, including one from the Public Works
Department, were roped in to establish the cause of the collapse and have
come up with proposals for repair work.
“I will brief the Cabinet and we shall take it from there,” he said.
About 60% of the stadium’s roof collapsed on June 2. The RM300mil stadium
had been opened in May last year.
