Rain and more rain. The past two winters in Oregon have far exceeded historical rainfall averages. The extra water pools, ponds, and courses across the land, but most of it still needs to drain to our streams and rivers. As we alter our land uses, building house, roads, and other structures, new problems and concerns arise regarding drainage of surface water. These problems and concerns have become more prevalent by the encroachment of urbanization on our rural lands. Recently, several problems have arisen in the urban/rural interface; in one instance, considerable fill soil was brought in before new housing was constructed causing flooding of an existing house. Attention needs to be given to the potential effect the additional fill will have on the natural drainage course. Whose problem is this? How do we come to a resolution? Was there a problem in the first place? Drainage issues can lead to property damage and civil suits. In order to avoid problems we need to understand our drainage rights in Oregon.
