  • Everything you ever wanted to know about Flight Paths

    You can think of any major airport as the most extravagant short-term parking lot imaginable, with an equally extravagant quickie-mart. Both are connected to a 1super-highway. But instead of one on and off ramp, there are many known as Standard Instrument Departures (SIDs) and Standard Terminal Arrival Routes (STARs). SIDs are the flight procedures that

    The current Port of Seattle grant programs began in 2016 with a proposal by Commissioner John Creighton–responding to the uproar over the Flight Corridor Safety Program.

  • Port Package Property Costs

    Occasionally, we post certain pages to the news feed to remind visitors that we are, above all else, an information source. There is a difference between 'data' and 'reports' and information that is useful to those who want to make change. This report tracks the costs paid for by the Port of Seattle on homes, apartments and houses of worship between 1987 and 2024, including where and how they were funded down to each parcel, project and cost center. Anyone interested in the issue of Port Package updates needs to become familiar with these kinds of statistics and begin diving into our library of more than 100 reports, maps and charts. If you don't find what you are looking for, sending us a research request.
