At my HS in the 90s students were frequently used to do stuff like this. Ex: this ravine/brush area we want to clean it out and chop some stuff down to make it a "nature center".

Similar in woodshop and metal working - doing stuff to fix the schools infra/bldg.

It's actually the basis of community building. The students take some ownership of the area they work/live in by fixing/building for others.

Wonderful idea.
