I also heard that since the land they bought was swampy they let construction companies dump excavated dirt there to fill in.

Yes, that is how you reclaim land in a swamp.

They dig water channels to lower the water table and drain the swamp. They then backfill with whatever solid material they can find and let it compress over a few years. Because it's still a swamp, any organic material quickly rots away, leaving nice fertile soil behind.

Boston harbor was reclaimed with literal trash. The city dumped all it's garbage into man made dikes to back fill and create the land. What is now the highest property prices in New England.
