Sustainable Integrated Watershed Management in the Tualatin Basin

A Watershed Approach to Improve Water Quality: Case Study of Clean Water Services’ Tualatin River Program1

“…Planting trees, providing land rental payments, and releasing stored water costs a small fraction of the refrigeration option. As of 2007, the riparian portion of the trading option in both urban and rural areas had cost US$4.3 million, a 95% cost savings compared with traditional approaches (Roll et al. , 2008).…”

“…, 2008). The process of prioritizing restoration sites, investing in science‐informed site preparation and maintenance, and basing restoration on regional conservation strategies is likely to produce many additional environmental benefits, such as increased species habitat, removing pollutants from runoff, and helping to control erosion (Roll et al. , 2008).…”

“…Riparian shade credits are created by programs in rural and urban areas of the Tualatin that have planted over 400,000 trees and shrubs a year over the life of the permit (Roll et al. , 2008).…”

“…The urban portion is managed directly by CWS, working with public and private landowners to restore riparian corridors within the urban areas. Some projects are implemented through a volunteer, community tree planting program called the Community Tree Planting Challenge, which set a watershed goal of planting over 1 million trees by 2025 (Roll et al. , 2008).…”

“…Temperature is monitored at the watershed scale. Results are reported annually to DEQ as part of CWS’ permit compliance (Roll et al. , 2008).…”
