Surface and Subsurface Cont m nation Report'APN:251-050-03*Parcel Nos-174 Designated Remainder CAPAY CLAY Capay Clay is a very deep and wet soil on a 0%to 2% slope. The soil is of alluvial derivation from mixed rock sources with a high water table as a result of irrigation water. It is at elevations from 25 feet to 140 feet, in a climate with annual rainfall of ten(10) inches and average temperature of 60 degrees Fahrenheit with 270 frost-free days. The soil has a high shrink-swell factor and permeability is generally slow and the available water capacity is high. The soil color of the soil below the ground surface at various depths are listed as follows: 0 to 20 Grayish Brown/Dark Grayish Brown/Dark Brown 20 to 60 Pale Brown The percent of clay, soil type, plasticity index,permeability and density at various depths below the ground surface are listed as follows: DEPTH SOIL TYPE PLASTICITY PERMEABILITY %CLAY DENSITY In Inches) INDEX (Inches/Hour) (Grams/cc) 0 to 20 Clay 20-35 0.06-0.20 40-60 1,30- 1.50 20 to60 Clay/ Silty Clay 20 -35 0.06-0.20 40 - 60 1.30- 1.50 DEPTH SOIL TYPE LIQUID SHRINK AVAILABLE WATER In Inches LIMIT SWELL CAPACITY(In/In) 0" -20" Clay 40-60 High 0,14-0.16 20" -60" Clay/Silty Clay 40-60 High 0.14-0.16 The rate of water intake for the soil is 0.1 inches per hour. The general use for this soil is for irrigated crops and a few homes. Some problems that are associated with development of the property are(1) slow permeability, (2)high shrink-swell potential, (3)high water table and (4) low strength. ZACHARIAS CLAY LOAM The Zacharius series consists of well-drained soils on alluvial fans and low stream terraces. These soils are very deep. They formed in alluvium derived from mixed rock sources. Slope ranges from 0 to 8 per cent. Soils of the Zacharius series are fine-loamy,mixed thermic Typic Xerochrepts and can be found 250 feet north and 350 feet east of the southwest corner of Section 5, T. 3 S., R 5 E., Tracy Quadrangle. 0 to 6 inches; dark grayish brown clay loam,very dark grayish brown moist; weak fine subangular blocky structure; hard, friable, sticky and plastic; many very fine and Caryl and Marie Than 77709 Cnllth r ammera Rnari Tram r'ai;fnmia 95'476. 0091 R'i5- 5910 6
