Table 15.--Building Site Development (Part 2) 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 local roads and streets evaluates the following soil properties at variable depths in the soil:
flooding, ponding, wetness, slope, organic Unified classes for low soil strength (PT, OL or OH), amount of clay, depth to
hard or soft bedrock, depth to thick or thin cemented pans, fragments greater than 3 inches in size, soil bulk density
and the potential of the soil to cave.
The interpretation for shallow excavation evaluates the following soil properties at variable depths in the soil: flooding,
ponding, wetness, slope, subsidence of organic soils, shrink-swell potential expressed as linear extensibility percent
(LEP), potential frost action, depth to hard or soft bedrock, depth to thick or thin cemented pan, fragments greater than
3 inches in size and soil strength expressed as the AASHTO group index number (AASHTO GI).
