Download the data
Every record on this site is downloadable, with the publishing agency named on each row and a link back to the agency record it came from. Take it and use it — the attribution requirements of the underlying agency licences travel with the rows.

How we treat the data
Nothing is invented. If an agency does not publish a parking count, this site does not show one — no estimate, no “N/A”, no dash. A missing field means the agency does not record it.
Every field is traceable. Each attribute records which dataset it came from, down to the individual row, and each ramp page links back to the publisher’s own record.
Sources are used only where licensing is clear. Federal agency output is public domain; state datasets are used where the agency publishes a licence or attribution statement. Where licensing could not be established, the dataset was left out — including the single largest aggregation we found, which would have added several thousand records.
Named places only. Launch sites an agency publishes without a name do not get a page, because a page titled “Boat Ramp” helps nobody.
