Ordinance Exhibit DOrdinanceExhibitD DOWNTOWN RIVERFRONT LAND USE COMPONENTS CA 19-1,RA 19-1,Z 19-5,WG 19-3,ST 19-3,and SDR 19-2 April 19,2019 Therefore,this standard is met. (b)Grading and excavating conducted as part of restoration or enhancement projects,and bank and channel reconfiguration shall result in topography that resembles landscapes shaped only by natural processes,for example,incorporating the undulations,meanders and slopes found in such landscapes.For purposes of this standard,straight lines and geometric or angular shapes are not acceptable.Channel and stream bank slopes shall not exceed 25 percent at elevations of 500 feet or less. All grading and park development and enhancement work within the /WR conservation areas is shaped to meet the aesthetic established by this standard using undulating and swooping geometry reflective of the movement of water.In addition,in Phase One of this project permitted under Standards Review (SDR 19-001),approximately 500 linear feet of the steep rip-rap covered bank will be laid back to create more gentle slopes within the new Riverfront Park.The new bank condition provides the opportunity for extensive replanting,removal of a structural bank armament condition, and much better views to the River from the top of the bank. Within this area,however,new public improvements will be constructed including two new overlooks (North Overlook at 5th Avenue and South Overlook near the Steam Plant);construction of pedestrian walks and seat walls;installation of a shade pavilion (5th Avenue);and construction of wood viewing decks and seating structures.These areas will also be served by site lighting,additional park furniture, interpretive art installations and storm water treatment and meadow landscape planting areas.These are all important components of the public improvements to the Riverfront Park envisioned in the EWEB Master Plan and subsequent design work that was heavily informed by public input and long term downtown planning for decades.These fully accessible park elements provide critical visual access to the Willamette River and the landscape beyond and around the park site. From a filling,grading and excavation perspective,the proposed overlooks will likely have the greatest impact to /WR conservation areas.Concept level cross sections shown on Sheet WR 105.1 (Exhibit B.3:Standards Review Plan Set)are the most helpful to identify areas where concrete footings and other support structures will be constructed and their relative heights,depths,and square footage areas.These overlooks provide key arrival points at the River at the end of view corridors identified as critical design components of the Downtown Riverfront redevelopment site. Landscape areas surrounding these overlooks and associated developed park components are largely planted with native species and the additional riparian bank enhancement area created by reducing the slope of the riverbank between the two overlooks more than mitigates for the areas of pavement included as improvements in the area. Therefore,this standard is met. (6)Impervious Surfaces.Within the /WR conservation area,construction of new impervious surfaces shall comply with the following standards (a)Impervious surfaces are prohibited within the /WR conservation area unless they are part of a use approved in accordance with EC 9.4930(3). As noted previously the proposal involves uses pursuant to subsection EC 9.4930(3)(b),specifically construction of public improvements.Therefore,this standard is met.
