agencies from using land from publicly owned parks, recreation areas (including recreational trails), wildlife and water fowl refuges, or public and private historic properties, unless there is no feasible and prudent alternative to that use and the action includes all possible planning to minimize harm to the property resulting from such a use. Several wetlands and roadside ditches are present within the TAMP study, but the wetlands are not classified or delineated on national or local wetland inventories. Small pockets of wetland vegetation would be impacted by the project; mitigation for lost wetlands would be required as part of project construction. Consultation with the National Marine Fisheries Service through the Federal Aid Highway Program programmatic biological opinion process also will be required. The consultation would consider potential effects due to changes in base and peak stream flows caused by new impervious surface and potential impacts to water quality within the study area as well as in waters downstream of the study area discharges (including Senecal Creek, Mill Creek, the Pudding River, the Willamette River, and the Columbia River). There are no critical fish or wildlife habitats designated within the study area, and no Endangered Species Act-listed fish, animal, or plant species are present within the project area. The project would remove some riparian vegetation adjacent to a non-fish-bearing stream and mitigation for lost riparian vegetation would be required. Only one historic resource was identified in the Oregon Historic Sites Database; the Big Eddy-Chemawa No. 1 (Historically Oregon City-Chemawa No. 3) Bonneville Power Administration Transmission Line, constructed in 1955, is eligible for listing in the National Register of Historic Places (NRHP). No adverse impacts to the towers are anticipated by the proposed interchange improvements. Two locations of historic debris scatter and/or farmstead features were identified during an archaeological survey conducted for the TAMP project.These areas/features are recommended for further evaluation for their potential for listing in the NRHP. Section 4(f) applies to archaeological sites that are on or eligible for the NRHP and that warrant preservation in place, including those sites discovered during construction; thus, if this archaeological site is eligible for listing and is important to be left in place, a Section 4(f) evaluation could be necessary. There are no designated public open space or scenic areas in the vicinity of the interchange. Impacts to natural and historic resources are minimal and mitigation requirements are identified in the TAMP. Goal 5 has been met. STATEWIDE PLANNING GOAL 6: To maintain and improve the quality of the air, water and land resources of the state. The TAMP documents that the project area is in attainment for all air quality requirements and the project does not require an air quality analysis. The project triggers stormwater management requirements due to the addition of new impervious surface, full depth roadway reconstruction, and the alteration of drainage patterns. Along with stormwater treatment, the project triggers stormwater detention requirements because the receiving waters drain a watershed smaller than 100 square 1-5:Aurora Donald Interchange(Exit 278)TAMP:Supporting Findings for Marion County Adoption 8
