Reliable hydrology for suburban growth

While specific drainage classes are not listed, the high soil score of 67.6 indicates very favorable conditions. The balance of sand and silt usually prevents the severe drainage issues found in heavier clay soils. Observation of local runoff patterns will confirm how your specific site handles rain.
