UNIVERSITY OF OREGON NORTH CAMPUS CONDITIONAL USE & WILLAMETTE GREENWAY PERMIT APPLICATION determined that the edge of the river and riparian buffer were most critical in terms of restoration priorities because of the need to protect the river and provide beneficial shade to aquatic species 11 dependent on cooler water. In addition, most ecological functions need at least a 100- to 200- 12 foot riparian buffer, with 200 feet accommodating the functions more optimally. A 200-foot setback allows more area for: Providing shade and cover that is beneficial to fish, birds, and animals (and not good for most 13 invasive plants), ; Removing the existing fill and re-grading the river bank to a more natural slope, allowing trees 14 to better access water, improving groundwater recharge, and improving views and access to the river; Improving flood storage function, removing sediment and contaminants, improving erosion 15 control, and increasing channel stability; Providing habitat for sensitive species; Passive recreation, such as soft trails; 16 Outdoor teaching related to ecology; and Creating a buffer from other potential uses, such as recreational fields and the bike path. After the Conceptual Study, in response to stakeholder and wider community feedback gathered throughout the process, the university revised and clarified the Master Site Plan and Conditional Use Permit application in the following ways for the area north of the railroad tracks. All of these commitments are well beyond what the code would require (as further described in the description of the Master Site Plan (Section 5). Created a riparian enhancement setback of 200 feet from the top of bank (of the Willamette River and Millrace Outfall) for buildings and recreational fields, expanding opportunity for riparian restoration; Further reduced the proposed coverage (maximum footprint) of potential buildings (from 18% to 15% in Area 4, from 2% to 0.5% in Area 5, and from 25% to 16% in Area 6). This reduces the potential scale and quantity of buildings; Further reduced the proposed height of potential buildings proposed east of the Frohnmayer Bridge from 45 feet to 37 feet. This also helps to reduce the scale of buildings; Reduced the quantity of potential recreational fields from five to three to allow for a 200-foot minimum setback . This would still accommodate the necessary types of physical education classes and field sports, but not the anticipated demand. This greatly increases the distance of the fields and potential field lights from the 100-foot required conservation area; Added an additional bike path option further from the riverÈs edge, outside the 100-foot required conservation setback; Committed to treating stormwater runoff from potential fields; 11 Riparian Assessment and Management Report by Mason, Bruce & Girard, 2018, pg. 10. 12 UO Riverfront Botanical Survey Presentation, 2012, Professor Bitty Roy, Institute of Evolution and Ecology and Biology Department. 13 UO Riverfront Botanical Survey Presentation, 2012, Professor Bitty Roy, Institute of Evolution and Ecology and Biology Department. 14 Riparian Assessment and Management Report by Mason, 2018, Bruce & Girard, pg. 11. 15 Riparian Assessment and Management Report by Mason, 2018, Bruce & Girard, pg. 10-11.
