On average, since inception, 89.34 monthly Illicit Discharge Detection and Elimination (IDDE) assessments are made through site visits. Since inception, only one significant event has occurred which involved a spill of heating oil during a winter storm when a overflow mechanism failed. The resulting effect was the cleaning of approximately a half mile of the city stream network.
Program Changes since 2007
In 2007, most people were not aware of what IDDE was. In 2019, all field personnel in contact with citizens are looking for potential problems and reporting concerns to the Stormwater Program Manager either directly or through department supervisors. Due to the average retention of 9.72 years of service for the 71 employees (91 employees including seasonal), annual training occurring during the Flagger Training Course typically is a refresher course.
