pollution abatement, and recreation. However, the amount of floodplain restoration that could be done on this site is dependent on political and community support and economic viability. Given the volume and unknown quality of much of the fill material, the strong flow of the river as it pushes against the outer bank of this curving portion of the river, and the economic value of this site, it is unlikely to be considered a high priority site for ecological restoration alone. However, there are a number of important things that could be done to enhance both ecological functions and human experiential values in highly complementary ways. A significant length of riverfont exists between the EWEB headquarters and the steam plant building, providing approximately 800 feet of bankline available for potential modifcation, especially above the Ordinary High Water Mark. C. Recommendations for improving the ecological function of the current design proposal that explore various interactions and tradeoffs among design and ecological function based on modifications of bank topography and river edge complexity. In the full report, we used the design concept representative sections created by Rowell Brokaw Architects to assess the expected effects of the proposed EWEB Riverfront Master Plan on aquatic functions of the Willamette River ecosystem in comparison to current and historical site conditions. This summary assumes that the baseline configuration of the master plan has been retained. Based on current master plan documents, there has been a moderate increase in upper bank excavation, which would increase the 10 -year and 20 -year floodplain extent and potential riparian functions of these areas. Given that the master plan has incorporated these recommendations, we have omitted the remainder of this Section C from the summary report. Readers who wish to review this section should refer to the full report. 16
