harden soft Ground of a FARP ?

[Dagobert666]

1. Is there a way for me as a mission builder to harden the soil of a FARP?
Maybe with a script?

2. It's no problem to remove houses and trees using the Remove Scenery trigger. But unfortunately, the waist-high grass usually stays where it is. Can I somehow remove this?
