SOIL SURVEY

-147-WR4 Map Unit (Gleyed Orthic and Gleyed Cumulic Regosols )This map unit is characterized by imperfectly drained soils developed o ncalcareous, medium textured, fan alluvium . Textures of silt loam with less tha n20% coarse fragments are typical of this map unit . Mottles are usually present i nthe soil profile .Table 56 .

Severe limitations for engineering uses are implied by th esusceptibility to frost heaving and the imperfect drainage .WR5 Map Unit (Gleyed Orthic Regosols )This map unit is characterized by moderately well to imperfectly drained soil sfound on calcareous, stratified, gravelly fan alluvium . Textures are generally gravell ysilt loam to gravelly fine sandy loam with coarse fragment contents greater than 20% .A perched water table is sometimes present .
