Table 19.--Construction Materials (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 0.00 to 0.99. The closer the value is to 0, the greater the potential limitation.
Values of 0 are absolute limitations based on the soil property criteria used to develop the interpretation. Values
closer to 1.0 have less of a limitation. Limiting features with values = 1 have absolutely no limitation and are not
shown in this report. Rating classes are determined by the most limiting value.
Fine earth fractions and fragment limiting features 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 reclamation material evaluates the following soil properties at variable depths in the soil: the amount
of sand, clay, fragments, the Wind Erodibility Group (WEG), available water (AWC), soil pH, salinity (EC), amount of
sodium (SAR), carbonates and susceptibility of the soil to erosion by water (K-factor).
The interpretation for roadfill source evaluates the following soil properties at variable depths in the soil: shrink-swell
potential expressed as linear extensibility percent (LEP), depth to rock or cemented pan, wetness, slope, soil strength
expressed as AASHTO Group Index Number (AASHTO GIN) and fragment content.
