It has few limitations. Areas adjacent to levees are subject to lateral seepage in wet years when the water- level i s high . Depth to the water- table is more than 6 feet, but water- may be perched above the stratified substratum after- heavy rains or irrigations . Furrow, border, corrugation and sprinkler irrigation systems are suited to this so i I . Maintaining crop residue on or near- the surface reduces runoff, reduces soil blowing and helps to maintain the water- intake rate and organic matter- content . If this unit is used for homes i to development , general management considerations include rare flooding . Roads and streets should be located above the expected flood level . The map unit is in capability units I (MLRA-17) , irrigated and IVc-1 (MLRA-17) , nonirrigated. This map unit is vegetative so i 1 group A.
