Since late 2014, we have been focussing much of our effort on reviewing the Common Land Use Planning Process (CLUPP) in an effort to make future planning projects more efficient and successful. One question that has come up is about sub-regional planning. The Yukon Land Use Planning Council is mandated under Chapter 11 - Land Use Planning of the Umbrella Final Agreeement. However, this chapter references sub-regional planning minimally and provides even less guidance for the application of a sub-regional planning process. The need to develop greater clarity with respect to sub-regional planning was expressed by the Council in a submission to the10 Year review of the land claim agreements in 2004 and again in a letter to the First Naton of Nacho Nyak and the Yukon Government October 5, 2017. To explore how sub-regional planning could be a part of regional planning under Chapter 11, we recently contracted Ryder Communications Management to provide this analysis.
