Can't recall the exact ones, but apparently we have provincial laws which mandate our municipalities to uphold very prescriptive maintenance standards (mowed turf, etc.) For cemeteries. Those rules complicated our proposal to the point that it made more sense to prioritize other spaces like low use lawn areas in certain parks, at least for now. 

 @0c59af14 thanks, the cemeteries here have issues even affording for people to mow the grass. We were thinking of planting only in certain areas (not over internments) like along fences/borders, entrances/exit garden plots, main office garden, and planting trees in places where there needs to be shade.
