This study explores Transfer of Development Rights (TDR) programs across the United State and their implementation, investigating TDR programming and ordinance development. Some of the key findings from this research include that TDR programs can be effective at preserving agricultural lands as part of a larger toolbox of planning and zoning measures. Broad criteria for successful TDRs include setting specific, clear preservation goals and understanding local real estate markets. Effective TDR incentives include a mix of market-based and regulatory approaches. Intergovernmental TDR agreements are a potential tool to enhance regional collaboration on preservation efforts and are not expressly prohibited by Idaho Code.
