Drainage decisions carry extra weight over karst
Surface water that would simply run off in most places can instead work its way into karst voids around Bowling Green, so a drainage plan here is also, in part, a sinkhole-prevention plan.
What a drainage plan should specify
- Downspout and grading routes that keep water away from known low spots
- Sump and interior drain sizing appropriate to the property's karst exposure
- Response plan if drainage work reveals a developing void
- Sequencing drainage correction before structural repair
- Documentation of the finished grade for future reference
Structural fixes rarely hold without this first
Installing piers or bracing on Bowling Green karst ground without correcting how surface water moves around it is a repair that can be undone by the next heavy rain.
