THE controversial reclamation plans for Lamma's main village came under attack at a stormy meeting yesterday when it was learned that government officials plan to instal sewerage facilities for three times the present population. Fears were expressed that proposals were afoot to dramatically increase the number of people housed on the island. In addition, many residents of fishing huts and houses along a stretch of waterfront set for major reclamation could be compensated with housing off the island, it was revealed at the three-hour meeting. Public opinion was loud and uniformly critical as 14 government officials, who travelled to the island for the public forum, fought for order in a raucous session attended by 70 island residents. Many residents were surprised to hear that a proposed sewage plant would be designed to serve a Yung Shue Wan population of 6,800. The present village population was estimated at 2,000 to 3,000 by officials. ''Who decided that this was necessary?'' asked Tim Dobson, a Lamma resident for 13 years. ''If the residents don't want this, what is the rationale for these projects?'' The Government's plan to reclaim and redevelop Yung Shue Wan harbour would involve the construction of seawalls, roads, the island's first sewage treatment plant and storage facilities for construction waste, building material and dangerous goods. Island residents complained about the noise of construction and the environmental impact of the treatment plant and waste station on water quality in the harbour. Several Chinese restaurant owners expressed concern that government plans to move many eateries into a new multi-storey seafood complex would force them to trade charming sea views popular with weekend tourists for less appealing views of a rubbish dump. The loudest applause greeted suggestions that the Government consolidate industrial development around the huge island power plant, considered an eyesore by most Lamma residents. ''Since the power station has already spoiled that area,'' said one resident, ''why not put all industrial activity there?'' Island resident Liz Glover, who has spearheaded Lamma resistance to the redevelopment scheme, silenced the crowd with the presentation of an elaborate development plan credited to the Hong Kong Beautification Society. Unfolding her professional drawings, she showed a picturesque harbour with swimming pool, barbecue area and a protected beach. The rubbish site and sewage plant were still there, but screened by trees. Residents also complained about the lack of public involvement in the Government's plan. One resident noted that none of the planners were Lamma residents. Government officials struggled to maintain order as they detailed the first phase in the scheme. Engineer Simon C. K. Tam explained that the first phase would involve building seawalls near the existing football pitch, construction of roads and reclamation of 1.2 hectares of land. He said the first phase was set to commence in mid-1995, with a 20-month period of construction expected. ''Two years of misery to anyone living near there,'' retorted resident David Slough. Lamma residents were severely critical of the lack of consultation, with most listing new development at the bottom of priorities. Officials said additional public comment could be made when an ordinance was gazetted in July or August.
