A November 2001 letter from Northwest Hydraulic Consultants, written on behalf of the Airport Communities Coalition, raises serious technical objections to the Port of Seattle's proposed plan to manage low streamflow impacts from SeaTac Airport's third runway construction on Miller, Walker, and Des Moines Creeks. The letter argues that the Port's analysis contains critical flaws, including an incorrect assumption that virtually all runway runoff infiltrates into adjacent grassed filter strips, and that the use of hourly rather than shorter time intervals in hydrological modeling causes stream impacts to be underestimated and mitigation storage facilities to be undersized. The consultants also express concern that the Port was not adequately addressing outstanding public comments or certification requirements set by regulatory agencies such as the Washington Department of Ecology.
