These are the competing Enfield and Mineola soils and the Montauk , Plymouth and Riverhead . Mineola soils are in a drainage sequence with Hempstead. Riverhead and Montauk soils are on nearby terraces or elevated moraines. Riverhead soils are sandier in the solum and Montauk soils have dense substrata. Plymouth soils have sand or loamy sand textures throughout and all lack the thick dark colored surface horizons that is typical for Hempstead.
Surface runoff is slow to moderate.
Permeability is moderate in the A and Bw horizons and rapid or very rapid in the 2BC C horizons. The lower part of the solum tends to retain higher than normal moisture for short periods due to change in pore space between the solum and substratum. Most areas were originally used for farming but most have been converted to housing developments and similar urban uses since 1940. Most underdeveloped areas are in parks or along older parkways. It is a single contiguous area and is 12,000 to 15,000 acres in extent.
