What the ground in Bremerton is like

The USDA soil survey rates mapped ground in Bremerton for septic drain-field suitability across roughly 28 square miles. About 97% 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 Bremerton, 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 66% of the rated ground here.

The limiting features the survey records most often here:

• Slope65.7%
• Depth to saturated zone48.5%
• Seepage, bottom layer44.2%
• Depth to bedrock25.3%

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.
