1 1 4.0 MINNESOTA STATE SITE FILES 4.1 Previously Recorded Archaeological Sites 1 A total of 15 archaeological sites have been previously recorded within one mile of the alignment of the Study Area (see Figure 4). Of the 15 archaeological sites, thirteen are pre-contact and consist of: six lithic scatters, two artifact scatters, three single artifact finds, and two American Indian earthworks. The remaining two sites consist of post-contact historic structural ruins with associated artifact scatters. None of the previously recorded sites are listed in the Nation Register Considered Eligible Findings ("CEF") by the SHPO. A total of 19 previously recorded historic architectural properties were identified within the Study Area (see Figure 4). Of the 19 historic architectural 1 properties none are listed on the NRHP or CEF. A summary of the inventoried archaeological and architectural sites is provided in Table 1. Because the Project is located in close proximity to Lake Minnetonka which is a highly sensitive archaeological area, and within one mile of documented Native American earthworks, it has the potential to contain additional pre-contact cultural resources. However, much of the proposed Project and transmission line route lies near or within wetland areas making traditional survey methods nearly impossible in these locations. Under these circumstances, where traditional survey methods prior to the start of construction are difficult to undertake, URS recommends that Xcel Energy has an unanticipated discovery plan in place prior to the start of construction. The unanticipated discovery plan should outline procedures to follow, in accordance with state and federal laws, if archaeological materials or human remains are discovered prior or during construction. The two American Indian earthworks (21HE0184, and 21HEam) located within the cultural resources study area warrant special discussion as they are protected under Minn. Stat. Section 307.08 of Minnesota's "Private Cemeteries" Act. While it is known that not all earthworks contain human burials, they are protected as such until authenticated by the Office of the State Archaeologist (OSA) and the Minnesota Indian Affairs Council (MIAC). Neither of the earthworks located in the cultural resources Study Area have been authenticated. Of the two sites, one is located approximately- away from its nearest point to the Proposed Route width and the other is approximately _ away from its nearest point to the Proposed Route. Given the distance between these sites and the proposed construction activities, no impacts are anticipated. Based on recent aerial photographs, it appears that an existing transmission line passes along the 1 northern boundary of site 21HE0184, and a portion of site 21HEam may have been destroyed by residential development. 1 Orono Project Phase Ia Literature Review April,2011 1 MPUC Docket No. E002/TL-11-223 10 i 1
