Since 2001, Waukesha County has sponsored an annual storm water workshop that focuses on a particular element of construction site erosion control and storm water management.  A planning committee made up of local communities, DNR and other partners helps plan each workshop.  They have consistently been well-received and the information presented can be a useful reference for years to come.  Listed below are links to presentations from some recent workshops:
