FOUNDATION ENGINEERING <br /> <br />4 May 1983. <br /> <br />Mr, Jack Isberg <br />12704 Ehlen Rd., N.E, <br />Aurora, OR 97002 <br /> <br />Project P-127 <br /> <br />Isberg R.V. Park <br /> <br />Dear Mr, Isberg: <br /> <br />We have completed the foundation investigation requested by your architect, <br />Mr. Richard Webb, for the proposed expansion of the Isberg R.V, ParE. Our <br />findings and recommendations are summarized below. <br /> <br />Background <br /> <br />Preliminary plans provided by Mr. Webb indicate that you plan to build a <br />conven)ence store and a fuel island at the Isberg R.V. Park, located on <br /> <br />Ehlen Road at the I-5/Aurora interchange. We understand that the convenience <br />store will be a single story structure with slab-on-grade, framed construc- <br />tion. The fuel island will include construction of a 36 by 66 foot canopy <br />which will be supported by four piers. Footing loads for each pier have <br />been estimated to be about 20 kips. <br /> <br />The purpose of our work was to provide recommendations for site preparation <br />and foundation construction of the convenience store and fuel island. <br /> <br />Subsurface Exploration and Site Conditi.ons <br /> <br />We dug three exploratory test pits cn the site on 2 May using a tractor-mounteJ <br />backhoe. Test Pit 1 was dug near the northeastern corner of the proposed <br />convenience store. Test Pit 2 was dug near the midpoint of the southern wall. <br /> <br />James K, Maitland PhD., P.E., 3930 N.W. Titlicum Place, Corvallis, OR 97330 503/757-7645 <br /> <br /> <br />
