Admasu v Port of Seattle Avigation Easement Class Action Memorandum Opinion

Notes

King County Superior Court Memorandum Opinion by Judge Bruce E. Heller in Kebede Admasu et al. v. Port of Seattle, Cause No. 09-2-22569-9 KNT. Port of Seattle seeks summary judgment against 126 plaintiffs owning 96 properties subject to avigation easements, in a suit by 300+ residents near Seattle-Tacoma Airport for inverse condemnation, nuisance, and trespass based on aircraft noise. Opinion examines avigation easements obtained under RCW 53.54 (Aircraft Noise Abatement), the Port’s voluntary soundproofing/noise insulation program, the 1993 change from ‘full and unrestricted easement for all aircraft’ language, homeowner participation agreements, and sound insulation contracts executed before notaries as free and voluntary acts.
