What this means
What Bakeoven soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Bakeoven soils is neutral: pH 7.0 (most land between 6.7 and 7.0), the range most vegetables, flowers and lawn grasses prefer.
Loamy topsoil (loam, silt loam and similar) covers >99% of mapped Bakeoven acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is very cobbly loam (75% of mapped Bakeoven acres).
>99% of mapped Bakeoven acres is moderately well to excessively drained, which suits most garden plants.
For lawns and yards
On >99% 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 >99% of the acres in mapped Bakeoven soils very limited, 0% somewhat limited and 0% not limited.
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.
