What's happening now?

In 2021, the City started a pilot project using an innovative stormwater management technology called Continuous Monitoring and Adaptive Control (CMAC). CMAC is a cost-effective cloud-based software system that controls a valve placed on the outfall of stormwater detention ponds. Using this technology, the City can protect Monticello Creek by releasing water from the ponds in a way that more closely mimics how water flows in forested conditions. These projects are designed to have minimal visible impacts on neighborhoods.

The City has installed CMAC technology at two stormwater detention ponds in Monticello Creek Watershed. In 2023, the City Plans to install two additional systems. As part of this pilot project, King County will also install systems at two different ponds they own and manage within the upper portions of the watershed.
