The agreement was reached during the Board of Public Works meeting.

The company will handle post-construction monitoring, according to Brian Jackson, the city's utilities manager.

"They discussed this at the City Council meeting, and they'll be discussing it further at the upcoming City Council meeting," Jackson said. "They're going to gather data that will be utilized to determine our compliance with our designed storm requirements at our CSO (combined sewer overflows."

Also at the meeting, a new contract with Rumpke was approved. The contract extends the company's trash hauling and disposal services through March of 2020.

Mayoral Aide Bob Cooke said prices for the service won't increase for the first year of the extension. For the proceeding years prices will increase based on the consumer price index, not to exceed three percent.
