What This Means
Building & Foundations
About 45% of soils have significant building limitations, while the rest are generally suitable. Check specific sites carefully — conditions vary across the area.
Septic Systems
About 46% of soils have significant septic limitations, while others are more suitable. A perc test is essential — conditions vary across the area.
