Our current project is located on a plot of land that 3/4 of it was developed into commercial retail. It "appears" that the last quarter had electricity and water mains laid out for a future commercial development, however it has grown over with grassy vegetation. The site has now been rezoned and a mixed use commercial/residential 10 story building is going to be constructed.
My question is since it has grown to look some what like a greenfield is it classified as undeveloped or is it previously developed since it has been graded previously and does appear to contain some infrastructure below the "green field".

Thank you to anyone who helps!
