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 Planned construction projects involve (1)mass grading for the streets and utilities and riparian enhancement for the park area,and (2)park construction and further infrastructure development. The mass grading project will include riparian enhancement of the riverbank to lay back the bank to a gentler slope and grading to achieve design subgrade for the park area,streets,and utilities.The design includes provisions for managing environmental contamination that may be encountered below the soil surface.Contaminated media will be removed to below the proposed subgrade surface and the area will be capped to prevent direct exposure.Excavated contaminated soil will be managed in accordance with DEQ requirements.Anticipated management options include the beneficial reuse of soil as site fill below development surfacing (roads,sidewalks,concrete slabs)or disposed offsite at a landfill. The park construction and infrastructure development projects will involve excavation,relocation and removal/abandonment of existing utilities,roadway subgrade preparation,road and sidewalk construction,and park construction including a retaining wall and new pedestrian and bike paths. Final surfaces include concrete or asphalt paving,concrete walls,and imported topsoil over existing soil subgrade.Site development features will prevent contact with any remaining low-level contamination that may remain at the site,improving the health of the site.Construction of bike and pedestrian paths will improve a critical bike commuting corridor,which offsets vehicle traffic in downtown Eugene. In addition to the physical improvements discussed above,the planned construction projects change the land use from a public utility operations yard to mixed-use development and park,thus activating the area and creating a cleaner and safer human environment.Additionally,future development of the site will be required to adhere to existing policies and Best Management Practices (BMP)in the Citv of Eugene Stormwater Management Plan.Compliance with BMP's will be ensured through the building permit process. The proposal includes amendments to EC 9.6792 Stormwater Quality regulations,as included in Exhibit A:Code Amendments.The proposed amendments will not have an impact on the City's existing water quality protection level,which complies with State and Federal regulations.The proposed amendments ensure that treatment for stormwater quality will be ensured consistent with current EC standards and the administratively adopted City of Eugene Stormwater Management Manual.The proposed amendments modify current regulations to allow for the combined stormwater treatment facilities from both public and private development,to the extent that added capacity can be achieved in the shared system to be constructed on the subject site. The proposed amendments do not negatively affect the environmental factors specified in Goal 6. Therefore,the proposed amendments are consistent with Statewide Planning Goal 6. Goal 7 -Areas Subject to Natural Hazards:To protect people and property from natural hazards. Goal 7 requires local governments to adopt comprehensive plans to reduce risk to people and property from natural hazards such as floods,landslides,earthquakes,tsunamis,and wildfires.The City protects people and property from natural hazards through various land use and building code requirements.The proposal does not alter these protective provisions,nor does it propose development in areas identified to be unsuitable for development.Therefore,the proposed amendments are consistent with Statewide Planning Goal 7. Goal 8 -Recreation Needs:To satisfy recreational needs of the citizens of the state City of Eugene FINAL SUBMITTAL 21July 22, 2019, Work Session – Item 3
