Wednesday rain causes visible runoff into Lake Mendota

Controlling construction erosion

Grant Feature #1: Construction erosion inspections with Dane County

Did you know that construction erosion is a serious and ongoing threat to our lakes? Controlling construction erosion is one of 14 recommended actions to reduce algae blooms in the Yahara CLEAN Strategic Action Plan for Phosphorus Reduction. It is also one of eight focus areas in Plan 2020: A Clear Path Forward, Clean Lakes Alliance’s strategic operating plan.

With every failed, missing or improperly installed erosion-control measure, the risk of dirty runoff entering our lakes rises each time it rains. Whether this leads to a muddy street or a dirt-choked storm sewer drain, a mismanaged construction project can spell big trouble for water quality.

Jeremy Balousek with Dane County Land and Water Resources

About the talk

Dane County’s Science-based Approach to Regulating Construction Site Erosion

Since 1995 Dane County has implemented performance and science based erosion control standards on construction sites. Jeremy Balousek will discuss the advantages of using performance based requirements and how the county uses factors such as rainfall energy, soil types, slopes, and other site conditions to model the potential soil loss from construction sites. He will show how Dane County sets and implements performance standards based on the potential soil loss to limit the amount of soil that may leave a construction site. Examples of the success and lessons learned from this approach will be presented.

About the series

Yahara Lakes 101 is a series of educational events open to the public and a great chance for residents to learn more about the science behind the issues that affect our lakes. Each month we feature a different expert to make the science accessible and interesting to non-technical audiences. Yahara Lakes 101 is produced in partnership with the UW-Madison Nelson Institute for Environmental Studies, with hosting sponsor The Edgewater, presenting sponsor First Weber Group, supporting sponsor The Evjue Foundation, and media sponsor The Isthmus.

Yahara 101 is held both indoors and outdoors (weather permitting) at The Edgewater. Come at 7:30 a.m. for a meet-and-greet and to enjoy your coffee, pastries, and fruit. The program begins at 8 a.m., and class is dismissed by 9 a.m.
