The Water Quality Program coordinates the county-wide response to federal and state clean water regulations related to stormwater. The goal of the program is to protect the health of our streams, streamside areas and wetlands by avoiding impacts to streams from County operations and improving water quality.

See a time-lapse video of the 2017 Stark Street Culvert Replacement. The project replaced an undersized fish ladder with a culvert that restored the natural streambed and allows for fish passage.
