Gday im doing a design for someone, dont have heaps of experience with swales, just wondering if I can build a swale through the path of where a gum tree is to be chopped down, also does stump grinding remove the entire root mass of a gum tree to make this possible to work. Most of the gum trees in query are 30-40cm thick and about 10-15metres tall.
Am concerned about leakage of swales from remnant gum roots. Soil is hard clay pan soil of victoria
Any feedback much appreciated.
