Soil & Terrain Characteristics

Lehigh County spans the Great Valley and South Mountain sections. The Great Valley floor has deep, well-drained limestone soils ideal for agriculture but prone to karst features. South Mountain areas have shallow, rocky soils over Precambrian gneiss and quartzite. The transition zone between these geologies creates variable soil conditions across relatively short distances.

County-Specific Considerations

The Lehigh Valley's rapid development has converted many formerly agricultural properties to residential use. Older septic systems in the rural western and northern townships may predate modern Act 537 regulations. Karst terrain in the limestone belt requires careful site evaluation to avoid sinkhole-prone areas for drain field placement.
