Drainage in Southern Indiana β What Makes It Challenging
Southern Indiana's topography creates natural drainage challenges that many lots haven't been built to handle well. Clay soils with low permeability mean water moves slowly through the ground β it saturates easily and stays saturated. Flat or gently rolling lots near the Ohio River corridor have limited natural slope to drain away from structures.
Older neighborhoods in Jeffersonville, New Albany, and Clarksville were platted and built before modern drainage standards. Original grading has often been altered by landscaping, additions, and settling over decades, creating situations where water that once flowed away from the home now flows toward it.
Indiana gets meaningful precipitation distributed throughout the year β spring tends to be the most concentrated. A home that drains adequately in a normal week may flood during a wet spring because the drainage system was sized for average conditions, not seasonal extremes. We design drainage systems with actual rain events in mind, not just average days.
