What the ground in Hemet is like

The USDA soil survey rates mapped ground in Hemet for septic drain-field suitability across roughly 29 square miles. About 88% of the rated ground is classed "Very limited", the survey records severe restrictions for a conventional drain field across most of that ground.

In Hemet, the leading limit is flooding: parts of the mapped ground sit in areas that inundate from time to time. A drain field under water cannot treat or disperse effluent, and floodwater can lift untreated waste into the open. The survey flags that limit on about 81% of the rated ground here.

The limiting features the survey records most often here:

• Flooding80.7%
• Seepage, bottom layer73.1%
• Slow water movement39.1%
• Depth to cemented pan8.6%

This is survey data for mapped areas, not a substitute for a site evaluation on your own lot. Conditions on a single parcel can differ from the map.
