What This Means
Building & Foundations
Most soils are generally favorable for residential construction. Standard foundations are usually viable, though site-specific evaluation is always recommended.
Septic Systems
About 29% of soils have significant septic limitations, while others are more suitable. A perc test is essential — conditions vary across the area.
