I always understood the definition as "land that was previously used, then 
cleared to prepare for a different use. Lots are usually the site of existing 
structures or similar that were destroyed/demolished. 

With this definition, a vacant lot in a neighborhood (where a building or house 
stood) is definitely a brownfield. 

It is the opposite of greenfield construction - land cleared of native/natural 
habitat to be made ready for use for the first time - bulldozing a forest or 
filling in a swamp for construction. I was unaware of a pollution angle.
