Andrie Street Improvements <br />Ramsey, Minnesota <br />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 <br />No. Thickness Base Material <br />(in) Thickness <br />Native <br />Subgrade <br />Material <br />Notes <br />B-1 11/2 5 SP -SM SP 4%2 Feet of Existing Fill <br />B-2 2 5 SP -SM Sp 7 Feet of Existing Fill <br />B-3 2 6 SP -SM SP -SM 4%2 Feet of Existing Fill <br />B-4 3 4 SP -SM SP -SM 4%2 Feet of Existing Fill <br />B-5 2 7 SP -SM SP-SM/SC 4%2 Feet of Existing Fill <br />B-6 2%2 3 SP -SM SP -SM 2 Feet of Existing Fill <br />B-7 2 4 SP -SM SP 4%2 Feet of Existing Fill <br />B-8 1 y2 5 SP -SM SP 4%2 Feet of Existing Fill <br />B-9 1 3 SP -SM SP 4%2 Feet of Existing Fill <br />B-10 1 5 SP -SM SP 4%2 Feet of Existing Fill <br />B-11 2 4 SP -SM SP 4%2 Feet of Existing Fill <br />B-12 2 4 SP -SM SP 7 Feet of Existing Fill <br />B-13 2 4 SP -SM SP 4%2 Feet of Existing Fill <br />B-14 3 4 SP -SM SP 2 Feet of Existing Fill <br />B-15 4 5 SP SP 4%2 Feet of Existing Fill <br />B-16 3 4 SP -SM SP -SM 2 Feet of Existing Fill <br />B-17 4 4 SP -SM SP -SM 2 Feet of Existing Fill <br />B-18 3 4 SP -SM SP 4%2 Feet of Existing Fill <br />B-19 3 4 SP -SM SC/SP-SM 4%2 Feet of Existing Fill <br />B-20 2 4 SP -SM SP -SM 7Feet of Existing Fill <br />B-21 3 4 SP -SM SP -SM 2 Feet of Existing Fill <br />B-22 1 4 SP -SM SP -SM 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. Groundwater was not observed in the remainder 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 climate changes. Also, soil conditions between <br />borings may be conducive to localized seeps or perched water zones that may be permanent or <br />transient. <br />UTILITIES <br />The fill and native soils observed in soil borings were generally suitable for utility support. For utilities <br />with planned invert elevations within the existing fill, we recommend that at least the upper 1 foot of <br />Page 2 of 15 <br />
