Did you know leaves that collect on our streets every fall can harm our waters?
More than 50% of the annual amount of phosphorus in urban stormwater can come from leaves in the street! When it rains, stormwater flows through leaf piles in streets creating a “leaf tea” that is rich in dissolved phosphorus. This "leaf tea" travels through storm sewers making its way to our lakes, rivers and streams. Too much phosphorus can lead to toxic algae blooms, low oxygen levels and green murky waters, none of which are good for animals living in the water or those of us who use it for recreation.
In the fall, timely removal of street leaf litter can reduce the amount of phosphorus in urban stormwater by 80% compared to no leaf removal! Communities across Dane County are working hard to reduce stormwater pollution to protect our waters, but they can't do it alone. You can help!
4. Help spread the Leaf-free Streets message in your neighborhood! Sign up for a yard sign and check out the Leaf-free Streets Toolkit for resources.
The City of Madison and United States Geological Survey (USGS) are partnering on a study to determine the effectiveness of various street leaf removal efforts in reducing phosphorus to our waters. Click on the video link above to learn more or view the USGS Leaf Collection Study website (USGS).
If you rake, follow your municipality's Leaf Collection Guidelines. Contact them for more information.
