Walpole Sandy Loam This map unit is in the Connecticut Valley Major Land
Resource Area.The mean annual precipitation is 37 to 50 inches (940 to 1270
millimeters)and the average annual air temperature is 45 to 52 degrees F.(7 to 11
degrees C.)This map unit is 80 percent Walpole soils.20 percent minor
components.Walpole soils This component occurs on outwash plain terrace,
depression,and drainageway landforms.The parent material consists of sandy and '
gravelly glaciofluvial deposits from gniess,granite,and schist.The slope ranges
from 0 to 3 percent and the runoff class is very low.The depth to a restrictive feature
is greater than 60 inches.The drainage class is poorly-drained. The slowest '
permeability within 60 inches is about 1.98 in/hr.(moderately rapid),with about 5.2
inches (moderate)available water capacity. The weighted average shrink-swell
potential in 10 to 60 inches is about 1.5 LEP (low).The flooding frequency for this '
component is none.The ponding hazard is none.The minimum depth to a seasonal
water table,when present, is about 6 inches. The maximum calcium carbonate
within 40 inches is hone. The maximum amount of salinity in any layer is about 0
mmhos/cm(nonsaline). The Nonirrigated Land Capability Class is 4w Typical ,
