Table P - Water Management
Pacific Southwest MLRA Office Interpretations
The information in this table indicates the dominant soil condition but does not eliminate the need for onsite investigation.
The numbers in the value columns range from 0.01 to 1.00. The larger the value, the greater the potential limitation. The
rating is based on the limitation with the highest value. Only three highest value limitations are lisited. There may be
more limitations.
Fine earth fractions and coarse fragments are reported on a weight basis.
A brief rating criteria summary and abbreviations are listed on the last page of this report.

The interpretation for pond reservoir areas evaluates the following soil properties at variable depths in the soil: slope,
depth to hard or soft bedrock, depth to cemented pans, marly textures, gypsum content and permeability that is too high
allowing seepage.
The interpretation for embankments evaluates the following soil properties at variable depths in the soil: ponding, wetness,
depth to restrictive layer, fragments greater than 3 inches, salinity (EC), Unified classes for high organic content (PT,
OL, OH), Unified classes that are hard to pack (MH, CH), permeability that is too high allowing seepage, and piping as
determined by Atterberg limits of liquid limit (LL) and plasticity index (PI), sodium content (SAR) and gypsum content.
