Diagnostic Guide: Why Is My Yard Wet?
Not every wet yard needs a French drain. This guide helps identify the source of water problems, from roof runoff to subsurface seepage, and suggests appropriate evaluation steps before contacting a professional.
Identifying Roof Runoff Issues
A common cause of wet yards is roof runoff discharged beside a foundation because downspouts are short, disconnected, blocked, or poorly routed.
Inspect downspout outlets to ensure they direct water away from the structure. Solid-pipe extensions can provide closed conveyance for roof water.
Sources
Diagnosing Ponding and Grading
Possible causes of ponding to investigate include altered grading and low side yards between houses, fences, or retaining walls. These are diagnostic possibilities, not assumptions about a specific property.
A field evaluation is necessary because grading, fill, and construction compaction may not be resolved by county-scale maps.
Subsurface Seepage and Soil Constraints
Seepage may emerge downslope where shallow soil, rock layers, or fill interfaces redirect water. Soggy lawn areas often result from low infiltration, compaction, or a lack of a viable outlet rather than just heavy rain.
Soil conditions must be checked parcel by parcel using official resources like the USDA NRCS Web Soil Survey.

Karst and Floodplain Risks
In the Cave Springs area addressed by Rogers regulations, proposed infiltration systems may require municipal review. Floodplain status is address-specific and affects what drainage work is permissible.
A qualified local provider can help determine if a project requires special permits due to these constraints.
Frequently asked questions
Why does my yard stay wet after rain?
Wet yards can result from roof runoff, poor grading, trapped water in low areas, or subsurface seepage due to soil constraints. A qualified local provider can diagnose the specific cause.
Do I need a French drain for a wet yard?
Not necessarily. A French drain is one possible subsurface collection tool, but roof-water routing, grading, or surface swales may address the issue better depending on the source.
Can I install a rain garden where water already stands?
No. A rain garden should not be placed where water already ponds because restricted percolation can prevent proper drainage.
How do I check my soil conditions?
Use the USDA NRCS Web Soil Survey for official maps, but a field evaluation is necessary because grading, fill, and construction compaction may not be resolved by county-scale maps.
What if my property is in a karst area?
Karst sensitivity is an active planning issue in parts of the market. Proposed infiltration systems may require municipal review or alternative designs.
