UNIVERSITY OF OREGON <br />NORTH CAMPUS <br />CONDITIONAL USE & WILLAMETTE GREENWAY PERMIT APPLICATION <br /> <br />Natural Hazards (Goal 7) <br />C.31. When development is allowed to occur in the floodway or floodway <br />fringe, local regulations shall control such development in order to <br />minimize the potential danger to life and property. Within the UGB, <br />development should result in in-filling of partially developed land. <br />Outside the UGB, areas affected by the floodway and floodway fringe <br />shall be protected for their agricultural and sand and gravel resource <br />values, their open space and recreational potential, and their value to <br />water resources. <br />The subject property is located within the UGB. Portions of the subject property adjacent to the <br />Willamette River are located within the FEMA regulated floodway and floodplain, as shown in <br />Sheet S01 Existing Conditions (Exhibit A). The proposal does not advance development in ways <br />that are inconsistent with current standards nor does it modify or exempt existing regulatory <br />protection measures. By choosing to provide a riparian enhancement setback of 200 feet from the <br />top of bank for buildings and fields where practicable, the proposal appropriately considers the <br />impacts of potential flooding. <br />In addition, by incorporating ecological and riparian restoration techniques along the riverbank, <br />flooding impacts can be mitigated. More explicitly, the <br />Riparian Assessment and Management <br /> prepared by Mason, Bruce & Girard found that vegetated riparian areas reduce the speed <br />Report <br />and intensity of floodwaters by providing resistance to flows, which in turn reduces downstream <br />flooding and leads to effective flood storage. However, areas that perform these functions within <br />the development site were found to be historically reduced to narrow strips along the river, <br />reducing flood storage function. In order to improve these functions, the Applicant seeks to <br />incorporate as many applicable restoration techniques as possible as funding becomes available. <br />Two techniques proposed in the report include large-scale invasive plant removal, and removal of <br />concrete riprap along the shoreline. Both of these techniques can aid flood storage capacity. <br /> <br />The proposal also supports the need to infill partially developed land by providing the additional <br />services needed by the University in a more cohesive and organized way on a site that is <br />connected to public utilities. Based on these findings, the proposal is consistent with Policy C.31. <br />Willamette River Greenway, River Corridors, and Waterways Element <br />D.2. Land use regulations and acquisition programs along river corridors <br />and waterways shall take into account all the concerns and needs of <br />the community, including recreation, resource, and wildlife protection; <br />enhancement of river corridor and waterway environments; potential <br />for supporting non-automobile transportation; opportunities for <br />residential development; and other compatible uses. <br />Accounting for the needs and concerns of the community are at the foundation of the proposal <br /> <br />and land use process. The ApplicantÈs proposal addresses recreation, resource, and wildlife <br />protection; enhancement of river corridor and waterway environments; emphasis on supporting <br />non-automobile transportation; opportunities for residential development; and other compatible <br />uses. <br />Cameron McCarthy FINAL SUBMITTAL | June 22, 2018 58 <br /> <br />
