What the ground in Burlingame is like

The USDA soil survey rates mapped ground in Burlingame for septic drain-field suitability across roughly 4.4 square miles. About 79% of the rated ground is classed "Not limited", the survey records few restrictions for a conventional drain field across most of that ground.

In Burlingame, the leading limit is slope: the ground falls steeply enough that a level trench line is hard to hold. A drain field has to sit across the grade without concentrating flow downhill; on steeper parcels that layout gets tighter. The survey flags that limit on about 19% of the rated ground here.

The limiting features the survey records most often here:

• Slope18.7%
• Slow water movement2.9%
• Depth to bedrock2.5%

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.
