- TDR
- Transferable Development Rights. In order to maintain the agricultural reserve, many large properties
were rezoned in the 1980’s from 1 unit/5 acres to 1 unit/25 acres. In exchange for this rezoning,
the land owners were granted Transferable Development Rights (TDRs), which they could then sell
to developers. Other areas in the county were designated as TDR receiving areas. If a developer
bought a TDR, they could build a development in the TDR receiving area at a higher density than
it was originally zoned.
