AUG-20-97 WED 09:49 AM WOODWARD CLYDE FAX Na 6125930094 P. 04 <br /> Woodward-Clyde <br /> Mr. Bruce Polaczyk <br /> Hennepin County Department of Pubic Works <br /> December 17, 1996 <br /> Page 4 <br /> RECOMMEi\NDATIONS <br /> Preliminary construction plans for modifying CSAH 15 would have had an effect on four <br /> mounds within the group first identified by T.H. Lewis in 1883. These mounds,numbers 7, <br /> 8. 10,and 12,all are either within the current right-of-way or within the proposed <br /> construction limits. Woodward-Clydc recommended that Hennepin County modify the plans <br /> to avoid effects to the mounds,and to discuss all plans with the Minnesota State Historic <br /> Preservation Office and the Office of the State Archaeologist to ensure compliance with <br /> Minnesota Statute 307.08 concerning private cemeteries. Woodward-Clyde also <br /> recommended additional subsurface testing between stations 280+00 and 286+00 along both <br /> sides of the road,within the construction limits. This area,including portions of the ditch, <br /> appears to consist of relatively undisturbed ground and to have a high potential for containing <br /> buried archaeological habitation material. <br /> On September 20, 1996,Hennepin County redesigned the proposed roadway improvements <br /> to avoid effects to the burial mounds. Retaining walls were proposed near mounds 4,7,8, <br /> and 10 (Figure 3). The retaining walls would have the effect of protecting the mounds from <br /> future erosion. On November 25, 1996,a public hearing was held to discuss the proposed <br /> roadway redesign. City of Orono officials and local landowners were opposed to the new / <br /> design. It was decided that the roadway would be left as it currently exists. Any t/ <br /> improvements would involve only overlays with construction not go beyond current ditch <br /> cuts. <br /> Woodward-Clyde recommends that Hennepin County supply a copy of any future roadway <br /> improvements, including pavement overlays, of CSAH 15 near the vicinity of Brackett's <br /> Point to the State Historic Preservation Office fur comment,to ensure compliance with <br /> Minnesota Statutes 307.8 and 138.31-42. <br /> Sincerely, _ <br /> • <br /> — <br /> Michael Justin j <br /> Project Manager <br /> MAJ:sll <br /> Attachments <br /> Woodward-Clyde Consultants <br /> J YE 13030V INxl2 DOAI)•Dec96VAIN <br />
