    Port presents remedies for Sea-Tac Airport noise

    The Port of Seattle held a public open house at Sea-Tac International Airport on April 9, 2011, to present feasibility-stage proposals for reducing airport noise affecting surrounding communities. Mitigation options under consideration included building a hush house to muffle engine run-ups, installing air conditioning in uninsulated single-family homes within the updated 65 DNL noise boundary, providing sound insulation for multi-family and mobile homes, and assisting local jurisdictions with long-term land-use planning. The Port planned to submit its recommended solutions to the FAA by the end of 2011, after which the FAA would conduct a 180-day review to determine which measures it would help fund.
