Hi. Sounds like a good situation. You could think of swales as well to keep most of the
water on the
land, slowly infiltrating.
Bring all the water into a
pond high on the land and attract beneficial insects and creatures which will help stabalize your ecosystem and irrigate with the water.
Both options would lessen your need for high raised beds. The higher the raised beds get the more need for watering your shallow rooted anuals in dry times.
But it all depends on your situation.
