I have a question here @Arcanestomper , if we go for the first options, can we replace it with better build options later on after asking herbalist for better build idea aside from flooding ? (not to mention possibility of get another rare herbs from that region if he noticed it, which make this place even more value that the clan will want to invest in it protection)
You can change how you handle the valley later, but it will be harder to make that change after this vote.
