Table 16.--Sanitary Facilities (Part 1) 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 listed. 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 septic tanks adsorption fields evaluates the following soil properties at variable depths in the soil: flooding, ponding, wetness, slope, subsidence of organic soils, depth to hard or soft bedrock, depth to cemented pans, permeability that is too fast allowing seepage, and permeability that is too slow or an impermeable layer at shallow depth. The interpretation for sewage lagoons evaluates the following soil properties at variable depths in the soil: flooding, ponding, wetness, slope, organic Unified classes for low strength (PT, OL, OH), depth to hard or soft bedrock, depth to cemented pan, fragments greater than 3 inches in size, and permeability that is too fast allowing seepage.
