Abstract
  • The Tualatin River in northwest Oregon has been designated as water quality limited by the Oregon Department of Environmental Quality. Restoration and enhancement of riparian areas to improve water quality is one task to be pursued by management agencies. This paper examines some of the potential costs and benefits of undertaking riparian restoration and enhancement on two tributaries of the Tualatin. In general, the potential costs are likely to be more identifiable and have market prices associated with them. The potential benefits of riparian restoration are often public or non­exclusive in nature. Measuring and estimating prices for benefits was found to be more difficult. Although costs of restoration depend on the standards adopted, the costs for the two study areas were found to be approximately $6,000 per stream mile at one site and $21,000 per stream mile at the other site. The cost of retiring agricultural land from production was a major influence on the total costs and was significant in explaining the cost difference between the two sites.
