1 4.2 Previously Recorded Standing Structures Nineteen historic properties have been inventoried within the Study Area as part of various cultural ' resources inventories. Several rural properties within the Study Area were recommended for further evaluation during the previous resource studies but have not been subjected to such studies as of the completion of this literature review. None of the historic properties are located within the 400 foot Proposed Route width, with the nearest being approximately away, and will not be impacted by construction activities. 4.3 Previously Conducted Cultural Resources Surveys The reports for eight cultural resources inventories in the Study Area were reviewed. Another ' report submitted in 2003 was unable to be located during the March 2011 visits to the SHPO. A 1988 Reconnaissance NRHP Survey of 26 Municipalities in Hennepin County for the SHPO covered portions of the cultural resources Study Area documenting several standing structures. Several structures were recorded as potentially eligible for listing in the NRHP;however,none of the properties recorded for the 1988 report relating to this Project will be adversely impacted. Two reports document the Minnesota Trunk Highway Archaeological Reconnaissance Studies of 1993 and 1994. The Project location was covered within one of 8 segments where a 500 foot wide survey corridor was implemented. None of the sites recorded within these reports and relating to this Project are listed as potentially eligible for listing in the NRHP. The 106 Group conducted Phase II evaluations of two structures relating to reconstruction of County State Aid Highway ("CSAH") 6 in 1994. Both of the previously identified properties were found to be not eligible for listing in the NRHP. In 1995,a final report was submitted to the Minnesota Historical Society as part of the Trunk Highway Cultural Resource Program (Mather et. al. 1995) summarizing the results of surveys for several alternatives relating to improvements to U.S. Highway 12. Several archaeological sites were recorded as part of this survey,including 21HE0162,which falls within one of the Alternate Routes for this Project but outside of the 400 foot Proposed Route width. ' In 1997, the 106 Group submitted a Phase I report for the proposed reconstruction of CSAH 6 from Townline Road to U.S. Highway 12. The extreme southern extent of the 16 acre substation parcel was covered as part of this survey with a result of no findings. ' Phase II evaluations were conducted prior to improvements to U.S. Highway 12 in 1998 on two sites outside of the proposed 400 foot route width and existing substation site for the Project,but within the one mile cultural resources Study Area. BRW,Inc. found both sites to be not eligible for listing in the NRHP;however,a reported undocumented Euro-American burial at site 21HE0288 was recommended for monitoring during construction activities. Site 21HE0288 is approximately ' -away from the proposed Project. Orono Project Phase Ia Literature Review April,2011 MPUC Docket No. E002/TL-11-223 13
