Wet areas that persist after rainfall
If the ground stays soft for days, start with why does my yard stay wet for days?. That page is about leftover saturation, not only the puddle you could photograph during the storm.
Low spots and runoff direction matter because they decide whether new rain keeps feeding the same soil. Grading and swales change that direction. A surface drain collects what still ponds.
When a French drain may not be the answer
A French drain is the wrong first move if the yard is a bowl that still fills from above, or if a downspout is still emptying into the wet zone. It is a candidate when the surface is no longer the whole story and groundwater has nowhere to go.
French drain vs. grading is the decision page written for that fork. French drain installation is the service page once a trench is actually the fit. Yard drainage is the hub if you are not ready to pick.
Surface drainage and slope, without invented terrain
We do not describe Freeport’s soils, flood maps, or typical lots as verified facts here. What we can say is the same homeowner logic used on the Rockford pages: find the source, find the low point, find an outlet that will not create a new wet area.
If you searched Freeport because you are west of the metro, this is still that company, that phone number, and that exterior scope.
Services for a slow-drying Freeport yard
Grading and yard drainage first when shape is the issue; a French drain when the soil is holding water.
