The Petone, at the mouth of the valley, was proposed as the initial site for the settlement of Wellington by the Wellington Company. However the chosen site was prone to river flooding and so early settlement was relocated to the present Wellington City. A small settlement remained at the Petone site as the whole valley was believed to be well suited as farm land. Almost the whole valley was subsequently clear felled and converted to pasture. A small remanant of the early podocarp forest is preserved in Bartons Bush in Upper Hutt.
