Exhibit 1 CMLRB 112 Permit Application <br />Agile Stone Srs[ems. Ina. <br />Approximately 40% coarse fragments (gravel) occur throughout the profile at the sample <br />point though soils with lower coarse fragment contents are common. <br />On average, the soil overlying 60% of this unit in the azea of disturbance is salvageable to <br />a depth of approximately 9". Deeper salvage is restricted by a high coarse fragment <br />layer. The portion of the unit which is salvageable occurs in the southern portion of the <br />azea to be disturbed. It can be visually identified as the area having fewer surficial <br />cobbles and stones and a lower percentage of cactus present. Conversely, the azea <br />proposed to be disturbed which is not overlain with salvageable soils lies along the <br />northem edge of this unit and is overlain with a higher percentage of cobbles and rocks <br />and supports a compazatively vigorous cactus population. <br />Gravel Areas 1B, II and III Soils (Kim loams) occur on a southeast aspect at <br />slopes less than or equal to 1%. These soils appear to have been flood irrigated in the <br />past but have not been cropped recently. Some limited irrigation may have occurred in <br />combination with grazing activities. surficial soil cover over this block averaged 45% <br />vegetation, 25% coarse fragments (gravel), 10% litter and 20% baze ground. Depths to <br />high coarse fragment layers of the soil profiles ranged from 6" to 18", with the shallowest <br />depths associated with the southem portions of the block and the deepest with the <br />northern portions of the block. <br />The dominant soils have a sandy clay loam texture, a pH of 8.0 and an electrical <br />• conductivity of 0.4 mmllos/cm. All micro-nutrient levels aze within acceptable limits. <br />Therefore, this soil is of an acceptable quality for salvage and reapplication to areas to be <br />revegetated. Given the range of depths (6" to 18") to a high coarse fragment layer. This <br />soil is assumed to be salvageable to an average depth of 12" over the Block 1 portion. <br />Block 2 soils have a somewhat elevated concentrations of both macro- and micro- <br />nutrients potentially indicating a more active historic fertilization program. <br />2.5 Map Unit E Gravel Pit, Undisturbed and Visual Berm Area <br />This unit occurs on a neazly level bench, or terrace, below and to the east of Map Unit D <br />and is immediately adjacent to the borders of Tallahassee Creek. Approximately 90% of <br />this unit is overlain with soils 40" deep. The remaining 10% consists of more shallow <br />soils over a concentration of gravels, cobbles, and stones. This mapping inclusion occurs <br />around the borders of the unit with Map Unit D and the slopes leading down to <br />Tallahassee Creek. The dominant soil is the Kim loam as mapped by the SCS. As such, <br />a soil sample was not collected from this unit. <br />The dominant soil of this unit is suitable for salvage to a depth of 18" over 90% of this <br />unit. Salvage may occur over the remaining ]0% of the unit to varying depths <br />opportunistically. The volume available from opportunistic salvage cannot be calculated <br />with certainty. <br />• 6 <br />
