How to Prepare Your Storm Drain for Chicago Rainy

As Chicago heads into its rainier months, blocked or poorly maintained storm drains can quickly turn routine downpours into street flooding or basement backups. While local infrastructure does much of the heavy lifting, homeowners and property managers can improve flow by preparing drainage paths before the busiest storms arrive.

The goal is simple: keep water moving into the storm sewer system by reducing debris, leaves, and sediment that accumulate around inlets and grates. Even small improvements—like clearing a few inches of buildup and managing runoff from your yard—can make a measurable difference during peak rainfall.
