The changing demography of homes under the flight path
Homes mitigated by sound insulation systems represent a large portion of the scarce and highly desirable middle-housing market in the three cities within the DNL65 (Burien, Des Moines, Seatac).
This street of thirteen homes is typical of almost every street where people signed Avigation Easements and received sound insulation systems during the Third Runway era.
Not quite…
This street is also typical in that one home (the one with the blue ‘x’) has undergone major reconstruction. In this case due to a significant fire. The repairs passed all building code. However, if tested today, it would not meet the same noise reduction standard of a Port Package. As so often happens, and for reasons usually having to do with cost, the owner and contractor opted for a less effective solution.
Moreover, because the equipment (doors and windows) were updated outside the Port Package program, it is doubtful this home would ever be eligible for reimbursement by any proposed FAA sound insulation repair/replacement program.
