Surface and Subsurface Cont a> tion Report*APN:207-290-03 & 16*Parcel Y 1,2, 3,4&Des.Rem. <br /> The soil is moderately deep to a hardpan and is moderately well drained. <br /> Typically the surface layer is grayish-brown sandy loam about 10 inches deep. The upper <br /> part of the subsoil is brown clay aboutl0 inches thick. The lower part to a depth of inches <br /> is a brown and/or pale brown, hard, silica-cemented hardpan. In some areas the surface <br /> layer is fine sandy loam. <br /> Permeability is very slow in the Madera soil. Available water capacity is low. <br /> Water is briefly perched above the claypan and hardpan after periods of heavy rainfall or <br /> irrigation. The hazard of water erosion is slight. The rate of water intake in irrigated areas <br /> is about 1.5 inches per how. <br /> The main limitations for homesite development are the depth to the very slowly <br /> permeable claypan and hardpan, a high water table, high shrink-swell potential and low <br /> strength in the clayey subsoil. Septic system absorption ability is also highly reduced by <br /> the claypan and hardpan layers. <br /> The characteristics of the two soils to be encountered at various depths below the <br /> ground surface are as follows: <br /> HONCUT SANDY LOAM <br /> Depth Liquid Plasticity Percent Permeability Shrink- <br /> In Inches Material Limit Index Clay (inches/Hour) Swell <br /> 0" -21" Sandy Loam 25-35 5- 15 7- 12 2.0-6.0 Low <br /> 21"- 60" Coarse Sandy 40-60 20 - 35 7- 15 2.0 - 6.0 Low <br /> Loam, Sandy <br /> Loam <br /> MADERA—ALAMO COMPLEX <br /> Depth Liquid Plasticity Percent Permeability Shrink- <br /> In Inches Material Limit Index Clay (Inches/How) Swell <br /> 0" - 12" Sandy Loam 20-30 NP-5 10-20 0.6-2.0 Low <br /> 12" -25" Clay 50-65 25 - 35 40 -60 <0.6 High <br /> 25"—34" Clay 50 - 65 25-35 40-60 <0.6 High <br /> 34' —60" Hard ------- -- --- -------- ------ <br /> DBCP &NURATE CONCENTRATIONS&UNDERGROUND TANKS DATA <br /> Maps entitled "DBCP and Nitrate—Land Use"available in the Environmental <br /> Health Department's office were consulted and contained the following chemical <br /> concentrations in the area of the subject property: <br /> No DBCP samples were taken in the area of the subject property; so no <br /> concentrations of this chemical have been determined in this area. <br /> rnr T.
