LEGISLATORS are expected to demand today that the Government speed up surveys of slopes near bus stops. A territory-wide survey has still not been completed more than a year after a woman was killed and five people injured in a landslide at a bus stop in Tsuen Wan. ''The Government gave the impression last year's survey was to be territory-wide. Instead it just covered the Kwai Tsing and Tsuen Wan area,'' said United Democrats infrastructure spokesman, Albert Chan Wai-yip. He said legislators were angry about being misled. The GEO has since widened the survey to cover all of Hong Kong. The survey's importance took on special significance after two incidents yesterday. Passengers waiting at a bus stop in Western had to run for their lives when heavy rain brought mud and rock crashing down at Baguio Villa, two years after a retaining wall collapsed nearby, killing two people. A blue China Motor Bus (CMB) sign was engulfed by the landslip. In the second incident CMB suspended a bus stop outside Caine Way Mansions in Seymour Road, Mid-Levels, after residents thought a nearby retaining wall was in danger of collapse.
