1.0 INTRODUCTION <br />1.1 Project Description <br />Final Grade, Inc. (Final Grade) is preparing to reconstruct the failed slope at 2807 Casco <br />Point Road in Orono, Minnesota. We understand that Barr Engineering previously <br />evaluated the slope failure and presented the owner with several different design options <br />to repair the slope failure. <br />Final Grade retained Haugo GeoTechnical Services to perform a geotechnical exploration <br />to evaluate the suitability of site soil and groundwater conditions and provide our opinion <br />on the proposed slope reconstruction at the site. <br />1.2 Purpose <br />The purpose of this geotechnical exploration was to characterize subsurface soil and <br />groundwater conditions and provide our opinion on the proposed slope reconstruction at <br />the site. <br />13 Site Description <br />The project site is located at 2807 Casco Point Road in Orono, MN. The site currently <br />contains one residential home that is located about 55 feet northeast of the crest (top) of an <br />existing slope along Lake Minnetonka. <br />The house area and backyard of the project site is relatively flat with the surface elevations <br />at the soil boring locations ranging from about 970 feet to 9691h feet. The slope is relatively <br />steep and is indicated at about 40 degrees on the Barr Engineering documents provided. <br />The height of the slope from the crest to Lake Minnetonka is about 30 feet. The slope face <br />generally contains small trees and brush with an existing stairway to Lake Minnetonka. <br />Portions of the slope face failed during a period of heavy rain in June 2014. The slope <br />failure was not repaired and portions were covered with plastic sheeting. <br />1.4 Scope of Services <br />Our services were performed in accordance with the Haugo GeoTechnical Services, LLC <br />proposal 16-0978 dated November 15, 2016. Our scope of services was performed under <br />the terms of our General Conditions and limited to the following tasks: <br />• Completing two (2) standard penetration test soil borings and extending each to a <br />nominal depth of 40 feet. <br />• Recording GPS coordinates of the soil boring locations and elevations. <br />• Visually/manually classifying the samples recovered from the soil borings. <br />• Performing laboratory tests on selected samples. <br />1 <br />
