Pedon Description: 2306904 | Pedon Description: 2306905
Unit (s): 069A, 069B
Classification: Sandy, mixed, mesic, Ortstein Typic Epiaquods.
Drainage Class: Poorly drained.
Parent Material: Sandy eolian and/or fluvial deposits underlain by loamy dense till.
Permeability: Moderate or moderately rapid in the sandy horizons, slow to very slow in the dense till.
Available Water Holding Capacity: Low.
Depth to Bedrock: Greater than 65 inches.
Seasonal High Watertable: Depth: +0.5 to 1.5 feet below the surface. Type: Perched. Months: November to May.
Hydrologic Group: C.
Hydric Soil: Yes (Mattapoisett soils are problem hydric soils, having spodic horizons).
Flooding/Ponding Potential: Frequency and Type: Commonly ponded (A slope only). Duration and Months: Moderately long, November to May.
Potential Inclusions: Ridgebury, Norwell, Saugatuck and Pipestone soils are similar inclusions. Very poorly drained Sippican, Swansea, Scarboro, and Berryland soils are on lower elevations. Moderately well drained Birchwood and Scituate soils are on higher elevations.
Agriculture: Poorly suited for most agricultural uses mainly due to wetness.
Woodland: Poorly suited due to wetness.
Development: Poorly suited due to seasonal high watertables at or near the surface for prolong periods of time and slow permeability of the substratum.
