` 4 Resufts Xerofluvents and Xerothents in the slightly lower landscape positions. Included areas make up about 15 percent of the total acreage. These inclusions are not listed as hydric by NRCS (2004). Permeability is moderately rapid in the Cortina soil. Available water capacity is low. Runoff is slow, and the hazard of water erosion is slight. • Vernalis-Zacharias complex,zero to 2 percent slopes, is not listed as hydric by NRCS (2004). The Vernalis soil is a very deep, well-drained,nearly level soil on alluvial fans. It formed in alluvium derived from mixed rock sources. In a typical profile,the surface layer is brown clay loam about 20 inches thick. The subsoil to a �,• depth of about 62 inches is yellowish-brown and light yellowish-brown clay loam. The Zacharias soil is also a very deep, well-drained, nearly level soil on alluvial fans. It formed in alluvium from mixed rock sources. In a typical profile, the surface layer is brown clay loam about 14 inches thick. The subsoil to a depth of 66 inches is yellowish-brown clay loam. In some areas, the surface layer is silty clay loam. The Vemalis soil makes up about 45 percent of the total acreage, while the Zacharias soil makes up about 40 percent of the total acreage. Included in this unit are small areas 6• of Capay soils on the lower positions and Stomar soils on slightly higher positions. Included areas make up about 15 percent of the total acreage. These inclusions are not listed as hydric by NRCS (2004). Permeability is moderately slow in both the �• Vemalis and Zacharias soils. Available water capacity is high. Runoff is negligible to low,and the hazard of water erosion is slight. • Vernalis clay loam,zero to 2 percent slopes, is not listed as hydric by NRCS (2004). This very deep, well-drained, nearly level soil is on alluvial fans. It formed in alluvium derived from mixed rock sources. In a typical profile, the upper part of the surface layer is brown clay loam about 9 inches thick. The lower part of the surface layer and the upper part of the subsoil are grayish-brown and brown clay loam and pale brown loam about 38 inches thick. The lower part of the subsoil to a depth of 60 inches is pale brown, fine sandy loam. The soil is calcareous between depths of 27 and 60 inches. In some areas,the surface layer is silty clay loam. Included in this unit are small areas of Manteca and Merritt soils in landscape positions similar to those of the Veritas soil and Tinnin soils on the slightly higher parts of the landscape. Also r included, in the slightly lower landscape positions, are small areas of saline-sodic Veritas soils. Included areas make up about 15 percent of the total acreage. These inclusions are not listed as hydric by NRCS (2004).Permeability is moderately rapid V in the Veritas soil. Available water capacity is moderate. Runoff is slow, and the hazard of water erosion is slight. • Vernalis loam,zero to 2 percent slopes,is not listed as hydric by NRCS(2004).
