EXHIBIT B -SITE DESCRIPTION The following site description information is generally contained within the existing MLRD Permit No. M-83-141 file. Where applicable, add'Rional descriptive information is provided to incorporate subsequent activities/disturbance and establish baseline conditions for the purposes of this Amendment application. (a) Vegetative Cover and Soil Description Soils The soils covering this area have been mapped as the Juget-Rock Outcrop Complex by the Natural Resource Conservation Service (NRCS). This rock complex is composed of approximately 50°~ very gravelly, sandy loam; 30°~ rock outcrop; and, small areas of soils in drainageways that can comprise up to 20% of each delineated area. The Juget-Rode Outcrop Complex consists of shallow, somewhat excessively drained soils that have formed on mountain slopes and ridges in a sandy residuum weathered from granite. It is found on slopes with a gradient of between 9% and 15%, and at elevations between 6,300 and 8,200 feet amsl. A representative profile of the Juget-Rode Outcrop Complex reveals asix-inch surface layer of dark gray, very gravelly, sandy loam and an underlying layer about five inches thick consisting of brown, very gravelly, loamy material on a granitic surface. The soil reaction of the Juget-Rode Outcrop Complex is slightly acid. The soils generally exhibit rapid permeability and low available water capacity. The predominant rode outcropping in the area is the Boulder Creek granite, which ranges from very coarse-grained pink and blade mottled biotRe granite to medium-grained quartz monzonite gneiss. It is commonly a dark gray color and fortes prominent outcrops. The small areas of soils near drainageways are dass~ed as either Peyton or Allens Park soils. The Peyton soils are formed on upland hills and valley side slopes in weli- drained, weathered, loamy and sandy material that has been locally transported. It is found on slopes with a gradient of between 5% and 20°~. A representative profile of this soil reveals a surface layer of dark gray, very gravelly, loamy sand about 11 inches thick. The subsoil is about 32 inches in thickness and is a brown, gravelly, sandy clay loam that grades to a gravelly, coarse, sandy loam. The substratum extends to a depth of 60 inches or more, and is a pale brown, gravelly, sandy loam. Moderate permeability and water capacity, as well as a neutral soil reaction characteristic, are associated with the Peyton soils. The Allens Park soils are formed on mountain slopes in loamy colluvium and residuum weathered from granite. These are moderately deep, well- drained soils found on slopes with gradients of between 15% and 60°~ at elevations between 6,300 and 8,200 feet amsl.
