    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.
