Economic, social impacts cited By Eloise Aguiar, ADVERTISER WINDWARD O`AHU WRITER KAILUA - About 300 people packed the multipurpose room at Kailua District Park last night to vehemently tell a City Council committee that they do not want Oahu's next garbage dump in their community. A bid to remove the Waimanalo Gulch site from the final list was declared illegal, and Rod Tam, who heads the City Council's Public Works and Economic Development Committee, said the council will not consider the recommendations of the advisory committee but only the facts and figures presented to the council.
