Surface Water Management
Surface Water Management provides water quality protection for the community by implementing programs to reduce pollution in our rivers, streams and wetlands caused by urban stormwater runoff.
Stormwater runoff is the most significant source of water pollution in our state. It washes pollutants into storm drains and drainage ditches, carrying silt, oil, chemicals, trash and pesticides to the nearest creek, stream or wetland. The polluted runoff can harm fish, aquatic life, and threaten our drinking water.
A Creek Runs Through It
Through watershed protection and planning, Water Environment Services is taking a long-term approach to protecting the health of our water resources.
What does the Surface Water Management program do?
- Maintains stormwater facilities, which capture and filter runoff
- Monitors water quality
- Ensures buffer zones between new development and wetland/creek areas
- Plans and designs regional water quality and flood reduction projects
- Provides long-term watershed planning
- Provides public outreach and partnerships for pollution prevention
Why do I pay a Surface Water Management fee?
Each resident of the community contributes to the cost of the program because we all use the buildings, streets, parking lots and sidewalks that contribute to the need for a surface water management program. Developers also pay for the cost of building the drainage systems and water quality facilities serving their development.
