Usually the only solution for managing a hilly lot is the construction of a retaining wall. While these walls can be constructed from many materials, by far the most durable are masonry (brick, block, or stone).
While the idea is to retain the soil behind the wall, you don’t want to retain water there. Consider adding gravel at the base of the wall on the uphill side and leaving weep holes every few feet in the base of the wall. This will allow ground water to drain down and through the wall instead of building up pressure behind it.
