1-5:Aurora Donald Interchange(Exit 278) Interchange Area Management Plan for Marion County Approval ODOT KN19062 Oregon Department of Transportation—Region 2 2.4.4.3 Critical Habitat The nearest critical habitat, not including the salmonid critical habitat in the Pudding River, is that of Kincaid's lupine (Lupinus sulphureus ssp. kincaidii) located approximately 25 miles west of the study area, and of Fender's blue butterfly(lcaricia icarioides fenderi) located approximately 26 miles to the south (USFWS ECOS).Therefore, critical habitats under the jurisdiction of USFWS would not be impacted by the proposed project. Additional detail for biological resources and habitats is provided in Appendix E. 2.4.5 Open Space and Parks The Aurora Acres RV Resort and associated grassy forested open space and picnic area are within the study area. The RV park and open space area are in private ownership.There are no publicly owned parks or other recreation resources, including trails and wildlife refuges within the study area or within one mile of the study area. The interchange is one of many ways to access Champoeg State Park, approximately 4 miles to the west of 1-5, but interchange improvements will not affect the park. Additionally,there are no planned parks or recreation projects within or near the study area identified in the 2010 Marion County Parks Master Plan (see Appendix G). 2.5 Hazardous Materials Parametrix conducted a Level I hazardous materials corridor study for the project in general accordance with ODOT and American Association of State Highway Transportation Officials guidance. Full details along with associated site photos can be found in Appendix H.The hazardous materials corridor study was conducted to identify potential sources of hazardous substances and/or petroleum products that may include an existing release, a past release, or a material threat of a release of hazardous substances to soil,groundwater, or surface water, and evaluate if the releases could affect the environment or create significant construction impacts. A review of historical information indicated that the project corridor was generally undeveloped until the 1950s when 1-5 was constructed, including the on-and off-ramps at Exit 278. Several businesses are located within the immediate vicinity of the interchange, including two large truck stops, an RV park, and a service station.These facilities were generally developed in the 1980s. Recognized environmental conditions (RECs) identified during the historical data review include the operation of the fueling areas and associated activities adjacent to the interchange for more than 35 years (see Figure 2-6 and Appendix H). • Several sites in the vicinity of the project corridor were identified on regulatory databases, including on the Oregon Department of Environmental Quality's (DEQ) Environmental Cleanup Site Information (ECSI) and Leaking Underground Storage Tank(LUST)databases, and the Spills database.Three sites were identified as having the potential to have impacted the project corridor and were identified as RECs. v The Travel Center of America truck stop is located immediately to the northwest of the interchange. The site has had known past releases to soil,groundwater, and surface water.The property is listed on the DEQ ECSI and LUST databases, and has had a number of spill incidents and known stormwater impacts. Based on the past incidents and operational practices, as well as its close proximity to the interchange area,there is some potential for residual subsurface conditions on or near the property that could impact future constructions activities. Thus,the Travel Center of America site represents a REC to the project corridor. The Leathers Oil site is located at the current Flying 1/Pilot Travel Center property to the southwest of the interchange.The property is listed on the DEQ LUST database and has had a number of spill incidents. Investigation and remedial actions have included a UST decommissioning, groundwater 2-14 July 2020 1274-3012-031
