Excel Thermal Model
The Dane County Erosion Control and Stormwater Management Ordinance (effective August 22,
2002) states that a stormwater plan required under the ordinance does not have to meet
thermal reduction requirements if the applicant can justify, by use of a model approved
by the Dane County Conservationist, that practices are not necessary because there will
be no post-development runoff temperature increase.
One model that has been approved by the Dane County Conservationist for estimating thermal
impacts is the Temperature Urban Runoff Model (TURM) developed by the University of
Wisconsin and the Dane County Land Conservation Department. Other thermal impact models
may also be used if they are approved by the Dane County Conservationist.
