Washington State's Substitute House Bill 1915, signed into law on April 30, 1993, expanded the tools available to port districts for addressing aircraft noise impacts on nearby properties. The law allows ports to offer affected property owners a range of remedies, including property acquisition, transaction assistance, soundproofing programs, and mortgage insurance. A key update permits individual properties to receive benefits more than once if they experience increased or changed aircraft noise levels that would have warranted a different level of mitigation.Open full document
