The SHPO responded that while known archeological sitesare located within the project boundaries, none of the sites is within an area proposed forsampling. Two general areas were identified to be within two of the sections contained in TargetNo. 1 and Carty Reservoir Bomb Target AOCs. In addition, a 7-mile stretch of the Oregon Trailcrosses the extreme southern portion of the former Boardman AFR and is considered a highpotential segment for archeological resources (Oregon Parks and Recreation Department [OPRD],2006; Appendix C).The USACE Seattle District contacted the Confederated Tribes of the Umatilla IndianReservation (CTUIR) concerning SI field activities. It was agreed that if any items of culturalsignificance were identified during field activities, the CTUIR Cultural Resources organizationwould be notified promptly.3.2.2 Coordination with Natural Resources OfficesThe Oregon Department of Fish and Wildlife (ODFW) was contacted to determine if there arethreatened or endangered species that could be impacted by field activities or future activities atthe former Boardman AFR. The ODFW indicated that only the Washington Ground Squirrelwould be potentially impacted. They recommended that the field team work closely with TheNature Conservancy, who manages the wildlife recovery area on the FUDS, to avoid impacts(ODFW, 2007; Appendix C).3.2.3 Historical Aerial PhotographsHistorical aerial photographs from 1958 and1965 were reviewed prior to preparation of this SI.The review confirmed the locations of AOCs addressed in this SI.
