Firstly, thanks PB for posting! This is a key step in building capacity & knowledge base in our community. The curriculum is based on IMBA guidelines and they are key fundaments to building sustainable trail. There are a number of other sources/guidelines/best management practices incorporated in the curriculum plus lots of local builder's knowledge from long time builders on the Shore including Digger. To respond to the earlier post from Trailsnob; IMBA is a very important advocacy group who has done and continues to do positive things for our sport as well as providing key technical insights to building sustainable trails.
