This 1979 Washington State legislative act amends the definition of an 'impacted area' for aircraft noise abatement purposes near airports. It expands the eligible zone from three to six miles beyond the paved end of any runway, and from fifteen hundred to thirty-three hundred feet from the runway centerline, within which port districts may undertake noise mitigation programs. Areas meeting these geographic criteria are officially designated as 'impacted areas' subject to noise investigation and abatement efforts.Open full document
