Standing water after a rain event is to be expected. It takes time for stormwater to infiltrate into the ground, especially after the surface has become saturated. Site grading allows water to flow away from a home’s foundation. In some cases, drainage easements are included in the site design and handle large amounts of runoff. Spring often brings heavy rainfall while the ground is still frozen. This leads to standing water on the frozen ground which is to be expected until the ground thaws.
