Watershed Protection Department

Originally called the Drainage Utility, the Watershed Protection Department was established in 1991 to manage the City’s creeks, drainage systems and water quality programs. Our focus is reducing the impact of flooding, erosion and water pollution.

To guide us in spending limited funds, we continue to assess the conditions in our watersheds and use the results to rate the severity of problems and prioritize projects.

We are mostly funded by the drainage charge on your utility bill. Some projects also receive bond or grant funding.

Read more about what we do and what we've accomplished in our Fiscal Year 2022 Annual Report.
