, �� � J-736-02 Page 3 The suitability of various soils for placement as structurat fill depends largely on the fines content (soil finer than the No. 20U mesh sieve) and the .noisture cont�:nt �t the timc of placement. This was discusse�i further in our December 20, 1978 report (see pages 8 through 11). If fill is to be placed during wet weather months, we recou�enc'. importing a clean, well-graded sand and gravel for use as structural fill. Consideration of East Wall Footing We understand the east wall line is planned to be located 15 feet west of the east propertp line and that the site grade is presontly about 10 feet in e]evation abcve the adjacent east proper`y. This would allow for a recou�eRded fill slope of 1.5 H:1V trom t.op af slab to the ground at the property. However, this situation woul.d require extending the f.00ting at least some 3 to 4 feet below top of slab. We reco��end that the footing baFe be extended below the plane of a 2H:1V s;ope projected from the outside bottom edge of r,he footing to the East property line. In addition, a minimum k foot horizontal distanc� should be maintained between the bottom edge of the footing and the 1.5H: 1V f.ill slope to allow for adequate soil cover against the footing. We wi11 include a detail depicting these recou�endati.�n's in our forthc��ming report. Drainage Considerationa Because of the nature of L-he fill soils, drainage of svrface water by infiltratian would be very slow. In our opinion, a w=11 desi�ned storm water system with catch basins in lower elevation areae would adequately handle surface runoff. We further recoun.�end that the exterior ground surface adjacent to the planned stx��ctuie be adequately sloped away from the building so that ponding of. water does not occur. Recotmoendations for Addi.tional Services We recor�end Hart-Crowser f. Asaociates, Inc. be provided the opportunity for a general review of final design and specifications. It is also recot�nended that we be rctained to provide continuing geotechnic9l engineering services �iuring the aite preparation and faundation excavation phases of this work. This is to observe compliance with the design concepta, specificatione or reco�ends- tions and to allow design changes in the event that sc�bsurface conditions differ from that anticipaCed prior to start of conetruction. �
