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 Create viewpoints that reach from the adjacent new development site out to river overlooks within the park. Integrate history and culture into the landscape via art-based interpretive element: Provide opportunities for activities,play,and programming within the park to encourage visitors from the community and around the world to experience and engage in the landscape of the river. Create a safe and inclusive park experience at any time of day or night for park visitors. The proposed development of a Riverfront Park within the subject site seeks to provide the maximum possible amount of landscaped area,open space,and vegetation as a core tenet of its use.As shown on Sheets WR 101.1 and 101.2 (Exhibit B.3),the Riverfront Park site is approximately three acres of linear park land along approximately 1,500 linear feet of the Willamette River. All proposed enhancement work is scheduled to occur above the ordinary high-water line.The proposed landscape design varies from native riparian enhancement approaches,to urban landscape forms using set percentages of native plants and an architectural design approach.The landscapes are restorative and educational in some areas,and more structural as support to hardscape and building design in others.Lawn area will provide open spaces for viewing and play,while stormwater treatment area plantings are designed for water quality treatment within an urban landscape setting. The Riverfront Park includes three types and locations of riparian enhancement in order to provide the maximum possible landscaped area,open space,and vegetation between the development and the river: 1)Riparian Enhancement -Grading and Planting The park site is narrow at the north and south ends to accommodate existing buildings on the river,namely the EWEB Headquarters buildings to the north and the decommissioned EWEB Steam Plant to the south.The site widens between these areas,allowing for a grading back of the bank to create a gentler slope;installation of a fabric encapsulated stabilization system; seeding;and replanting with native riparian species.This work will result in a rich and diverse river's edge habitat and will maintain the roughness needed to allow for slower water through this area. 2)Riparian Enhancement -Non-Native Species Removal,Pruning,and Planting In the narrower areas of the site,riparian enhancement activities will be limited to removal of non-native invasive species;pruning of trees to remain for tree health and improved views; and planting in the voids of the existing bank armament structures to promote new growth on the river bank. 3)Conservation Area Enhancement -Grading,Access,and Replanting At the very north end of the site between the EWEB North headquarters building and the Peter DeFazio Bridge,the project will construct an accessible path and renovate an area above the bike path with new native plantings.The area is currently overgrown with many non-native invasive species and has several concrete paths for viewing the river.This area is located within the Goal 5 Resource Conservation Setback for the Willamette River and as such will be revegetated with native riparian species.An accessible path will bring park visitors to the top of the bridge and provide additional seating and viewpoints along the way. In addition,the Riverfront Park plaza space is intended to support and be supported by a variety of development types surrounding the space.Permitted uses,such as restaurants,a hotel,and other City of Eugene 51FINALSUBMITTALJuly 22, 2019, Work Session – Item 3
