• Apmay clay loam, 0 - 1 percent slopes — Moffat Soil map # 5 <br />The 2 pond footprint/excavation areas are located on this soil type. <br />Approximately 35.9 acres will be disturbed for the 2 water surfaces. <br />Another 9.8 acres will be disturbed and reclaimed on the pond perimeters. <br />The 2C Horizon of this soil is the target aggregate resource at site. The 2C <br />Horizon material is very to extremely gravelly, non plastic sandy gravel <br />with 15-40% - 2 inch diameter to 10 inch diameter rock. A sometimes <br />thinning and discontinuous Apamy clay loam topsoil of 0 to 8 inches <br />overlies the aggregate material. Average seasonal groundwater may be <br />encountered from 3 to >6 feet BGL. The aggregate deposit is from 15 to > <br />25 feet in thickness and is derived from alluvial sources. The aggregate <br />deposit reflects a series of lateral meander loops to the south which created <br />a stacked river channel bottom and point bar depositional sequence. <br />• Weed sandy loam, 1 —12 percent slopes — Moffat Soil map # 209 <br />This soil type is located on the toe -slope and hillside area to the east and <br />northeast of the Pond #2 footprint excavation area. The hillside toe slope <br />lies along the eastern permit boundary and portions of this soil type will be <br />disturbed by some of pond area excavation and perimeter area concurrent <br />reclamation and road installation. Weed loam soil has some outwash off <br />the slope onto the Apmay clay loam topsoil in the flatter pasture and <br />underlying Apmay 2C aggregate material. Approximately 3 acres of this <br />soil type will be disturbed mostly by the concurrent pond edge reclamation <br />along the eastside (of pond #2) perimeter road. <br />• Fluvaquents — Moffat Soil map # 70 <br />This soil type is shown on the Soil Survey map lying across the south end <br />fence line of the 62 acre site. The Fluvaquents soils are generally found in <br />lower flood plains, oxbows, or depressions in stream terraces (in this case <br />a remnant oxbow). Water table is usually high and soils have a range in <br />characteristic from coarse to fine - loamy sandy to clayey stratified, friable <br />to blocky, hard to sticky and plastic with a basal gravelly C Iayer. The <br />residential water supply well was installed in a pit located in the soil <br />type and rock and gravel was observed to extend from the surface to <br />>25 feet BGL. The area where this soil is shown on the soil map within <br />the permit area has very thin and somewhat discontinuous topsoil/remnant <br />Fluvaquents loam covering the underlying gravelly aggregate target <br />materials. The landowner/applicant has stated the along the south fence <br />the rock and gravel has very little cover soil (<2 inches) and at most places <br />is on the surface. Most of this soil type (if present) will not be disturbed <br />as it is mapped outside the pond footprint areas. A small portion will be <br />disturbed and concurrently reclaimed within the final Pond 31 southern <br />end and the pond edge/road perimeter area.
