What this means
What Clebit soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Clebit soils is strongly acidic: pH 5.5. Most vegetables and lawn grasses do best around 6.0 to 7.0, so lime is often needed; blueberries, azaleas and rhododendrons like it as it is.
Loamy topsoil (loam, silt loam and similar) covers 96% of mapped Clebit acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is stony fine sandy loam (31% of mapped Clebit acres).
96% of mapped Clebit acres is moderately well to excessively drained, which suits most garden plants.
For lawns and yards
On 73% of mapped acres, rain soaks in slowly (hydrologic groups C and D, including dual groups that are D until drained). Expect runoff and puddles after heavy rain: core-aerate compacted lawns and keep ground sloping away from foundations.
For a septic system
For conventional septic absorption fields, NRCS rates 96% of the acres in mapped Clebit soils very limited, 0% somewhat limited and 0% not limited (4% not rated, such as urban land, pits or water).
Where the soil is very limited (slow permeability, a high water table, flooding, shallow bedrock or steep slopes), alternative systems such as mound or sand-filter designs are common and cost more.
Only a licensed site evaluation or perc test at the actual lot decides whether a system is allowed and which design.
