What this means
What Vista soil means for gardens, lawns and septic systems
For gardens
Typical topsoil in Vista soils is neutral: pH 6.7 (most land between 6.5 and 6.7), the range most vegetables, flowers and lawn grasses prefer.
Loamy topsoil (loam, silt loam and similar) covers 92% of mapped Vista acres: generally the easiest soil to garden, holding moisture without staying waterlogged. The most common surface texture is coarse sandy loam (87% of mapped Vista acres).
96% of mapped Vista acres is moderately well to excessively drained, which suits most garden plants.
For lawns and yards
Most land is in hydrologic groups B and C, where rain soaks in at a moderate pace.
For a septic system
For conventional septic absorption fields, NRCS rates 96% of the acres in mapped Vista 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.
