Dei Ms. Coulson: As requested, this letter provides soil parameters for ret9idng wall design nqutsted by Reraining Walis Company North. The parameters provided bin arc based on cwr gnviow analysis of the siw conditions premred in the rcferenL%d fetter. Wc understand thc walls ace proposed at the top of the existing 2: I (horizontal:venical) fill slopes at the rear of lots 85.86, and 88. Our analysis is based on amaximurn WaIl height ofapproximately 6 &et. The following parameters may be used fbr the design of the proposed Criblock walls. Retained and Foundation Reirrfoxced Zone An inrd m'crion an& of 38O may bc assumed for the reinforcecl zone if hpond crushed aggregate basc mnxerial is used. An allowable bearing capacity of 1.500 psf may be used for design, based on a minimum depth of embedment of 2.5 feet into dcnse, compacted fill measad wnically fiom the outside bottom edge of the foundation member tc, the slop hce. Footing excavations should bc obscrvd by a rcpmsentativc of our firm to evaluate whether the Wing mattrials are as assumcd in our analysis. The inclination of temporary hck-cuts should not exceed 1:1 (horimnta1:vcrtical). We have Dssumed that the soil grade in fkont of the dl will be rnainfaincd to dcsip grade. Surcharge loads and hybostalic prcsswcs were not included b our analysis. If these arc applicable, we should be contacted for revirions to the recommendations provided hcrrin. Backfill material should be compacted to at least YO percent of rhe laboratory maximum dry density in accordance with ASTM D 1557. If importsds MC ucd for wall backfill, they should bc text& by Geotechnics Incozporatcd to compare the &ear s%ength and unit weight Wws to nctual design dues. We recommend the mils used as backfill be predominantly firce draining, graaul~~, free of organic and clay materials, and haw a very low expansion potmlial (Expansion Index of 20 or less). Adequatc drainage should be provided to relieve hydrostatic pressures. The recommendations prescntedherein are considered generally consistent with meduds typically used in southm California, and have been develupcd wing the hree of cpT4 and skill ordinarily exercised, under simiilar circumstanccs, by reputable geoteehnical consuhants practicing in this or similar localities.
