Legislators have threatened to summon the head of the Urban Renewal Authority to explain why the body has failed to come up with an operating plan nine months after it was established. They have also decided to complain to the Chief Secretary on the slow progress of urban renewal projects. At a meeting of the Legco planning, lands and works panel yesterday, lawmakers accused authority chairman Lau Wah-sum of failing to attend meetings to 'avoid his responsibility'. Democrat James To Kun-sun said: 'It is stated in the law that he should come to explain what's happening in his authority. It's time for the public to know the truth.' The panel has instructed Mr Lau to turn up for a meeting on February 8, which a spokesman for the authority said yesterday he would attend. The lawmakers said the authority must also provide a timetable on proposed projects. The Urban Renewal Authority Ordinance states that the chairman and managing director of the authority must attend Legco meetings when requested to answer lawmakers' questions. But Mr Lau was not at two meetings he was asked to attend after the authority was established in May to replace the Lands Development Corporation. Billy Lam Chung-lun, managing director of the authority, denied Mr Lau was avoiding the legislature. He said the slow progress was due to complicated issues such as resettlement and land purchases. The legislature passed a motion last month condemning the authority for its efforts on slum clearance and renewal projects. The authority has a brief to redevelop 200 slums in 20 years. But it has only come up with an 'early project' to redevelop three sites in Wan Chai, Tai Kok Tsui and Shamshuipo at a cost of $2.6 billion. It has yet to devise a long-term strategy. Chan Yuen-han of the Federation of Trade Unions and Emily Lau Wai-hing of The Frontier criticised the authority for failing to fulfil a promise made by the Government before the creation of the body to expedite 25 projects announced by the former corporation. Deputy Secretary for Planning and Lands Cheung Siu-hing said the projects were still a priority and would be included in the authority's first five-year plan.
