''Soil amendment guidelines (from 2010 guide section 3 - placed here by Jen)
{{textbox|1=Soil amendment sizing criteria:
impervious area / soil area = 1
*use 100 mm compost, till to 300 - 450 mm depth
impervious area / soil area = 2
*use 200 mm compost, till to 300 - 450 mm depth
impervious area / soil area = 3
*use 300 mm compost, till to 450 - 600 mm depth
Compost should consist of well-aged (at least one year) leaf compost. Amended soil should have an organic content of 8-15% by weight or 30-40% by volume.

#Subsoil scarification (i.e., decompaction treatment) depth changes from minimum of 10 cm to 45 cm;
#Topsoil/Planting Soil depth for tree pits changed from minimum of 60 cm to 20 cm;
#Total uncompacted soil depth changed from 30 cm to 65 cm for turf/lawn and planting beds, and from 90 to 65 cm for tree pits;
