101-Ustic TorriFluvents, loamy. These deep, well drained soils are on terraces and Flood plains along the Inyjor drainageways. Some of the larger areas of Lhese ells are in the .iinvn}' Creek Camp :uul IShu•k Squirrol Creek drainageways xnrl in the Ellicott area. Slope is U to y percent. The average annual precipitation is about 15 Inches, the average annual air temperature is about 48 duln'ecs F, and Lhe average, trust-free period is about 1:36 days. Typically, the surface layer is grayish brown to very dark grayish brown gravelly sandy loam to clay loam li to lti inches thick. The stratified underlying material, to a depth of till inches, ranges from heavy clay loam W sand.

These soils are occasionally Flooded. The hazy rrl of soil blowing in muderatc Ur high. About half of I,he acreage of those soils is used fur ir- rigated corn, bluegrass sod, and alfalfa and for dryfarmed whe:d.. The slow surface Ivnuff reduces Lhe need for in- tensive conservation measures. Must irrigated areas arc in the Ellicott area and the Jimmy Camp Creek area. The rest of the acreage is used as rangeland. 'I'6rsr soils :ur soil od In Ihr prod urliun ul' nal.ivr ~rgrl nl ion nail uldr lia~ gr: v.iug. 'I'hr :mils I'uvnr lull grasses.

The main limitation of these soils for urban use is Lhe hazard of tlourling. Buildings anti roads should not be n built along drainageways and on flood plains. Access roads must be designed to minimize frost-heave damage. Capability subclasses IIIe, nonirrigated, and Ile, ir- rigated.
