Stormwater is rain and melting snow that runs off surfaces that cannot readily absorb water. These surfaces include rooftops, pavement, compacted gravel lots, and even frozen ground. Stormwater runoff picks up pollution, can cause erosion and flooding problems. These problems occur when we alter the land and change the way water moves through the landscape.
As stormwater flows towards receiving waters such as streams, lakes, rivers or soaks into the aquifer, it picks up pollutants. These pollutants include things as sediment, airborne dust, pet waste, oil, grease, fertilizers, chemicals, litter and whatever else we leave on the ground or pour down our storm drains and grates.
As the City grows and more rooftops, driveways, streets and other hard or impervious surfaces are built, the land loses its capacity to soak up and carry away excess water. As a result, rain or snow events that might result in a flood once every 100 years in an undeveloped area can cause flooding every four or five years after development occurred.
A media filter is a type of filter that uses a bed of sand, compost, crushed granite or other material to filter water for drinking, swimming pools, irrigation, stormwater management and other applications. Media filters can remove pollutants in stormwater such as suspended solids, dissolved metals, oil & grease, and phosphorus.
Stormwater treatment wetlands (a.k.a. constructed wetlands) are structural practices that incorporate wetland plants in a shallow pool. As stormwater runoff flows through the wetland, pollutants settle and are broken down by biological process in the plants and soil. Wetlands are among the most effective stormwater practices in terms of pollutant removal, and also offer aesthetic value. Stormwater wetlands are fundamentally different from natural wetland systems. Stormwater wetlands are designed specifically for the purpose of treating stormwater runoff, and typically have less biodiversity than natural wetlands both in terms of plant and animal life.
The stormwater utility fee is based on the demand the property puts on the system. General Information on Redmond's Stormwater Utility and Stormwater Billing is in this publication: Stormwater Utility Fee.
The Stormwater Utility is financed with revenue generated by a stormwater utility fee that is charged to owners of developed property.
Each developed parcel in the City is subject to the stormwater utility charge. Drainage from most properties enters or impacts the City stormwater system in some manner. These facilities, which are generally located on City streets, require continual maintenance and improvement.
The stormwater utility also supports capital improvement projects for flood control, erosion, conveyance improvements, and regional water quality or detention facilities. The utility also monitors the health of local streams, constructs habitat improvement projects, and responds to State and Federal regulatory and permitting requirements.
The City of Redmond offers a wide range of convenient payment options including:

The City has been divided into 68 drainage areas – or watersheds – for study. We are taking a detailed look at each watershed to determine the best way to handle stormwater from existing and future development. Watershed plans will enable us to make better choices about how to plan, maintain, and construct our drainage systems so they can better meet the community's many needs.
We are improving the way we maintain ponds, swales, catch basins, drywells, ditches and culverts. We are mapping the location of each stormwater facility, monitoring their condition and tracking the time it takes to maintain them. This will help us determine which ones are working well, which ones aren't and which ones we need to replace immediately to save money.
PUBLIC INVOLVEMENT AND AWARENESS
We are informing the public about drainage systems, how they function and how to take care of them. This will help reduce threats to water quality and prevent flooding problems.
CAPITAL IMPROVEMENT PROJECTS
Stormwater funds pay for construction of projects by City crews and contractors to repair or rehabilitate failed stormwater facilities and construct new regional facilities to better manage stormwater throughout the City. Stream restoration efforts rely on Stormwater Utility support to repair eroded areas, restore fish habitat, and enhance stream buffers.
