Ago Ramsey, <br />Street Improvements <br />Ramsey, Minnesota <br />N%.� NTI Project No. 15.61197.100 <br />The boring locations and depths were determined by City of Ramsey personnel. The borings terminated <br />at nominal of 10 feet below the existing ground surface. NTI assumes a ground surface elevation equal <br />to zero for every location. Subsurface conditions are summarized in the table below. Please refer to the <br />boring logs for additional information. <br />Table 1: Pavement and Subgrade Summary <br />Apparent <br />Boring Bituminous Aggregate Fill) Subgrade SubgradeNative <br />No. Thickness Base Material l Notes <br />Mater <br />(in) Thickness Material <br />B-1 1 %2 <br />5 SP -SM <br />SP <br />4 %2 Feet of Existing Fill <br />B-2 2 <br />5 SP -SM <br />SP <br />7 Feet of Existing Fill <br />B-3 2 <br />6 SP -SM <br />SP -SM <br />4 %2 Feet of Existing Fill <br />B-4 3 <br />4 SP -SM <br />SP -SM <br />4 %2 Feet of Existing Fill <br />B-5 2 <br />7 SP -SM <br />SP-SM/SC <br />4 %2 Feet of Existing Fill <br />B-6 2 %2 <br />3 SP -SM <br />SP -SM <br />2 Feet of Existing Fill <br />B-7 2 <br />4 SP -SM <br />SP <br />4 %2 Feet of Existing Fill <br />B-8 1 %2 <br />5 SP -SM <br />SP <br />4 %2 Feet of Existing Fill <br />B-9 1 <br />3 SP -SM <br />SP <br />4 %2 Feet of Existing Fill <br />B-10 1 <br />5 SP -SM <br />SP <br />4 % Feet of Existing Fill <br />B-11 2 <br />4 SP -SM <br />SP <br />4 %2 Feet of Existing Fill <br />B-12 2 <br />4 SP -SM <br />SP <br />7 Feet of Existing Fill <br />B-13 2 <br />4 SP -SM <br />SP <br />4 %2 Feet of Existing Fill <br />B-14 3 <br />4 SP -SM <br />SP <br />2 Feet of Existing Fill <br />B-15 4 <br />5 SP <br />SP <br />4 %2 Feet of Existing Fill <br />B-16 3 <br />4 SP -SM <br />SP -SM <br />2 Feet of Existing Fill <br />B-17 4 <br />4 SP -SM <br />SP -SM <br />2 Feet of Existing Fill <br />B-18 3 <br />4 SP -SM <br />SP <br />4 %2 Feet of Existing Fill <br />B-19 3 <br />4 SP -SM <br />SC/SP-SM <br />4 %2 Feet of Existing Fill <br />B-20 2 <br />4 SP -SM <br />SP -SM <br />7Feet of Existing Fill <br />B-21 3 <br />4 SP -SM <br />SP -SM <br />2 Feet of Existing Fill <br />B-22 1 <br />4 SP -SM <br />SP -SM <br />4.5 Feet of Existing Fill <br />GROUNDWATER AND GROUNDWATER CONTROL <br />Groundwater was observed in borings SB -21 and SB -22 at depths of 7 and 8 feet below the ground <br />surface, respectively. <br />Groundwater was not observed in <br />the remainder <br />of our soil borings at the time of <br />our explorations. Groundwater elevations can change due to precipitation events seasonally, changes in <br />topography and site development, and due to long-term <br />climate changes. Also, soil conditions between <br />borings may be conducive to localized seeps or perched <br />water zones that may be permanent or <br />transient. <br />UTILITIES <br />The fill and native soils <br />observed in soil borings were generally suitable <br />for utility support. For utilities <br />with planned invert elevations <br />within the existing fill, we recommend <br />that at least the upper 1 foot of <br />Page 2 of 15 <br />
