The Redmond Urban Watersheds Initiative (RUWI) is a joint effort
of the Washington State Department of Ecology, United States
Environmental Protection Agency, and the City of Redmond to explore ways
to reduce stormwater-related impacts to the City's surface waters.
For this project, the RUWI team examined the relationships between land
use and pollutants generated by stormwater systems in
Redmond. To do this, the RUWI team:
- Summarized the history of stormwater management in Redmond.
- Examined interrelationships among land-use, impervious surface,
and surface water quality across Redmond watersheds.
- Examined the relationship between Bellevue, Washington's (an
adjacent city) storm-event water quality data (1988-1993) and
watershed impervious surface levels.
- Applied EPA's water quality duration curve methodology to
Redmond's streamflow and surface water quality data.
- Explored the relationship between several additional
landscape-levels, watershed land-use variables, and surface water
quality.
- Modeled alternative futures for Redmond's land-use and applied
them to future surface water quality.
The reports were completed in late 2008. Link to
