🚧 Construction Update: McCarty Park Trash Rack Improvements

Construction to install the new trash rack and debris interceptors at McCarty Park begins the week of August 10th. These improvements will help reduce the risk of flooding caused by debris buildup on the trash rack.

During construction:
Please be aware of trucks entering and leaving the work site at the intersection of 82nd St. and W. Arthur Ave. and along S. 82nd St.

The sidewalk on the south side of W. Arthur Ave. will be closed between 81st St. and 82nd St. Please use the sidewalk on the north side of W. Arthur Ave.

🌦️ Rain is on the way!
Before the rain starts, take a few minutes to empty your rain barrel so it's ready to capture incoming rainfall. Every gallon stored helps reduce stormwater runoff, ease pressure on our sewer system, and protect local rivers and Lake Michigan.

🍃 Quick tip: Check your rain barrel diverter for leaves and debris to prevent clogs and keep water flowing properly.

A 2026 Wisconsin Initiative on Climate Change Impacts, or WICCI, report found that the climate in the state will, “continue to become warmer and wetter, requiring coordinated action across communities, businesses, industries, and natural resource managers.”

Vavrus, who is the co-director of WICCI, said the state is seeing an “upward trend” in days where there’s a minimum of two or more inches of rain.

“We’re certainly seeing more extreme events overall, and we’re expecting more certain kinds of extreme events in the future, particularly more heavy rainfalls,” Vavrus said.

“The main reason we expect heavier rainfalls in a warming climate, as we’ve seen already, is because warmer air can hold more moisture,” Vavrus added. “That’s just a physical fact.”

Flood mitigation efforts are moving forward in the region as climate models predict heavier rainfalls will likely become more frequent in the state.
