I just finished two terms on Oregon landscape license board. We offered other options, too. Some college would substitute. And, various self-employment projects. In fact, if someone submitted 6 small projects per year - 4 years worth - that would open the door. And these could be like mowing, thatching a lawn: even single day projects (to my amazement, but that's the way it is, since they still face the test). Do they offer other options like that? You might need to ask.
