UNIVERSITY OF OREGON NORTH CAMPUS CONDITIONAL USE & WILLAMETTE GREENWAY PERMIT APPLICATION extent practical, through measures that may include reducing impervious surface in the floodplain and adjacent areas. By incorporating ecological and riparian restoration techniques along the Willamette River, flooding impacts can be mitigated. More explicitly, the Riparian Assessment and Management Report prepared by Mason, Bruce & Girard found that vegetated riparian areas reduce the speed and intensity of floodwaters by providing resistance to flows, which in turn reduces downstream flooding and leads to effective flood storage. However, areas that perform these functions within the development site were found to be historically reduced to narrow strips along the river, reducing flood storage function. In order to improve these functions, the Applicant seeks to incorporate as many applicable restoration techniques as possible as funding becomes available. Two techniques proposed in the report include large-scale invasive plant removal, and removal of concrete riprap along the shoreline. The Applicant has established self-imposed regulations regarding setbacks and maximum building coverage which reduce the acreage of impervious surface on the site. For example, the required conservation area setback within the site is 100 feet along the Willamette River and 40 feet along the Millrace. However, along the Willamette River and the Millrace Outfall, the Applicant proposes a riparian enhancement setback of 200-feet for buildings and recreational fields along most of the length of the property, as shown on Sheet L01 Regulatory Plan (Exhibit A). This setback requirement keeps impervious development well out of range of valuable riparian area, and fosters flood storage capacity within the floodplain. Along the Millrace, the Applicant proposes to maintain and enhance the conservation area and to restrict development to uses permitted in a conservation area. The Applicant has established a Regulatory Plan, Sheet L01 Regulatory Plan Exhibit A, that applies more self-imposed, stringent development regulations than is required by code in order to facilitate land in conservation, to manage and enhance waterways, and for viewsheds to be protected. For example, the Applicant has established regulations regarding maximum building coverage. North of the tracks, the Applicant is proposing maximum building coverages well below what is allowed by the code. The applicable S-RP zone states that at least 40% of the portion of the development site shall be shall be landscaped with living plant materials, requiring the building coverage and site elements to be contained within 60% of the development site (implying an allowed building coverage of 40% to 50%). To the west of the Millrace (Area 4), the Applicant proposes a maximum building coverage of 15%; to the east of Riverfront Parkway (Area 6), the Applicant proposes a maximum building coverage of 16%. Between the Millrace and the Riverfront Parkway (Area 5), the Applicant proposes a maximum building coverage of 0.5%, and maximum field coverage of 47%. The maximum building coverage to the south of the tracks is proposed to comply with existing S-RP coverage standards. Based on these findings, the proposal is consistent with Policies G.16 and G.19. Parks and Recreation Facilities Element H.4. Encourage the development of private recreational facilities. H.7. The City of Eugene shall cooperate with the University of Oregon in the resolution of any loss of recreational facilities associated with development in the Riverfront Park.
