These are the competing Broadbrook , Pittstown , and Rainbow soils and the Birchwood , Mansfield , Narragansett , Poquonock , Quonset , Stissing , Wapping , and Warwick soils. The moderately well drained Pittstown, poorly drained Stissing, and the very poorly drained Mansfield soils are associated in a drainage sequence. Birchwood and Poquonock soils have a sandy over loamy particle-size control section. Narragansett and Wapping soils have hue of 7.5YR or 10YR in the upper part of the B horizon and a friable substratum. Quonset and Warwick soils are on nearby terraces and are underlain by stratified coarse-textured deposits.
Surface runoff is medium to rapid.
Permeability is moderate or moderately rapid in the solum and slow or very slow in the substratum. Many areas are cleared and used for cultivated crops, hay, pasture, and nursery stock. Scattered areas are used for community development. Some areas are wooded. Common trees are red and white oak, gray birch, red maple, sugar maple, and white pine.
