FML, Inc. <br />' <br />STS Project 93589 <br />August 28, 1985 <br />-10- <br />3. Floor Slab Design <br />1 <br />garage <br />The floors for the <br />four- lex units w <br />p ill be a tuck -under <br />design with slab on -grade <br />floors, at approximately the present <br />round sur <br />face rface elevations. <br />We recommend that the existing topsoil <br />be stripped, and the loose <br />surficial soil be surface compacted or <br />removed and replaced using <br />proper densification in the area of the <br />garage floor slab. Where <br />fill materials will be required to sup- <br />port floor slabs, the fill <br />should be compacted to at least 95% of <br />the maximum Modified Proctor dry density. This would include <br />- <br />backfill against foundation walls and utility trenches below floors <br />and under sidewalk areas. <br />4. Pavement Design <br />The predominant soil type in the natural soil areas which will <br />comprise the roadway subgrade materials for this project will be <br />' silty fine sand. Recommendations for stripping in paved areas and <br />densification of surficial soils or fill materials have been pre- <br />viously discussed. For a subgrade consisting of silty fine sand, <br />we recommend that a Hveem Stabilometer value of 50, or a California <br />-� Searing Ratio (CBR) value of 20 be used for designing the pavement <br />t thickness. The fine v 1 pavement design should be based on traffic <br />loading, frequency and volume, as well as soil types. <br />EXISTING FILL AREAS <br />1. Earthwork <br />Within the area of known existing fill deposits, some development <br />is anticipated. Two four-p,lex buildings will be located near the <br />northern end of the existingfill <br />area, and bituminous drives and <br />parking areas are anticipated. Utilities on the site will connct <br />with existing utilities in Victoria Avenue, and will extend through <br />the fill area. <br />1 <br />
