A collaboration between Illinois-Indiana Sea Grant, the Chicago Metropolitan Agency for Planning, the Metropolitan Planning Council, and several other agencies across Illinois and Indiana, the new Outdoor Water Use Manual is now available from NWPA. Completed as part of a larger goal to help reduce and curb outdoor water use, the manual provides necessary information on discretionary water use, costs to utilities and municipalities, and steps to develop more efficient outdoor water use policies and plans.
 

The manual comes just as the height of the summer season has led some areas to enact strict watering policies or, in the recent case of Lake Forest, institute a temporary ban on outdoor watering altogether. 

 
Peter Wallers of the NWPA writes on page four of the manual, “The significance of this guide and what separates it from the average lawn care guide is its emphasis on efficient lawn care, using as little water and fertilizer as possible while achieving maximum performance for your lawn.” 
 
By providing information and planning steps for proper water and fertilizer usage, the manual offers not only steps for reducing current use levels, but gives municipalities a way to plan for sustainably meeting their needs well into the future.

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.Watch the 3-part video series at the link in bio.(Photo credit: Liz Spitzer, Illinois State Geological Survey, Coastal Research Group)
