Stormwater

Project 2

S T O R M W A T E R

Stormwater is water that runs off impervious surfaces such as roads, parking lots, and rooftops, as well as runoff from bare earth that can deliver excess sediment, nutrients and/or bacteria to surface waters. The CWU protects water quality by cleaning streets and treating the stormwater runoff containing bacteria, nutrients, heavy metals, and gas/oil through facilities such as bioswales, rain gardens, and created wetlands. The risk of flooding is also reduced by properly cleaning, sizing, and routing pipe and ditch infrastructure to receiving waters. Development and land disturbing activities are required to manage their stormwater as part of the land use permitting process. 

STORMWATER TECHNICAL ASSISTANCE

Stormwater permits are applied for through Community Development and SmartGov. Public Works provides review, approval and technical assistance to the stormwater permit process.
