Introduction , A.1 Purpose , This preliminary geotechnical evaluation was undertaken to make an evaluation of the site subsurface soils and appazent groundwater conditions relative to construction of a visitors center and paved parking areas at Noerenberg Memorial County Park in Orono, Minnesota. ' The evaluation will then be used by the Hennepin Parks Department of Planning and Engineering to design foundations and prepare grading plans and specifications for the ' project. ' A.2 Scope Three standard penetration test borings were performed in the area of the proposed visitors center. In addition, four power auger test borings were performed in the proposed parking ' areas. As part of our evaluation, several grain size analyses (number 200 wash) were performed on select soil samples for classification purposes. With the results of these borings ' and laboratory tests, this engineering report was prepared addressing our preliminary analysis and recommendations. 1 It should be noted this work was done according to our proposal dated November 11, 1991. A.3 Available Information , Prior to performing our evaluation, a meeting was held at the Hennepin Parks office in Plymouth to discuss the scope of the project. At that time, we obtained a site plan showing , the proposed visitors center and parking areas. The plan was prepared by Hennepin Parks and dated October 31, 1991. � A.4 Locations and Elevations The borings were performed at the locations staked in the field by Hennepin Parks. These aze ' shown on the attached sketch. ' Ground surface elevations at the borings were estimated from the surface topography shown on the available site plan. Thus, the elevations should be considered approximate. , ' �
