What the ground in Los Fresnos is like
The USDA soil survey rates mapped ground in Los Fresnos for septic drain-field suitability across roughly 4.4 square miles. About 62% of the rated ground is classed "Very limited", meaning the soil has one or more features unfavorable for a conventional drain field, and the limits generally cannot be overcome without major soil reclamation, special design or expensive installation.
In Los Fresnos, the leading limit is slow water movement: effluent does not drain through the soil fast enough, so a conventional field can back up or pond when the ground cannot keep pace. The survey flags that limit on about 95% of the rated ground here.
