Trees benefit cities by providing shade, purifying the air, absorbing rain water and creating natural habitats in our urban environments. However, each fall leaves create a phosphorus rich layer on the ground that is a major source of nutrient pollution to our lakes. The City of Madison and the United States Geologic Survey have been conducting a research project for the last 5 years in an attempt to quantify impacts of leaf management on water quality. This talk will cover results to date and describe how YOU can reduce leaf impact on the lakes.
Phil Gaebler is a water resources engineer for the City of Madison. He focuses primarily on ways to reduce the impact of stormwater on the lakes and streams near the City of Madison. This includes designing green infrastructure, detention basins, and innovative treatment technologies. In his role at the City, he also works on public outreach for many projects and is always looking for ways to effectively share how citizen actions can impact water quality.
