'Gentlemen: In accordance with your instructions and the outccnrs of discussions in our conference on Tuesday, September 15, 1987, we offer the following: It is our understanding that the proposed developnsnt will consist of tilt-up concrete construction over slab on grade. The structural loads are not known at this tine, butforthepurpose of this report, they are assunad to bs seventy (70) kips for calm loads and three (3) kips per lineal foot for wall loads. 1421 North Hundlev St.. Anaheim. CA 92806 (714) 630-9334 MADISONSWARJX PAFSWSRSHIP -2- W.O. 4422 SCOPE The scope of this report is based on planning information provided us, review of the currently envisioned site development, the geotechnical information contained in the above referenced report, geotechnical evaluation and preparation of this report. No additional field and laboratory work was performed for this report. SITS CBJDITICN.5 The subject site consists of six (6) rough graded vacant lots which cmprise the Western portion of the Palonsr Oaks Development. Msmede alterations to the natural topography consist principally of cuts along the South wall of the East-West trending Canyon De Las Encinas the soil fran which was used to fill along its floor. Existingvegetation consists of heavy chappsral along the Southern flanks of the canyon face. Professional landscaping was employed to protect cut slopes and graded pa&* Site topography is characterized by an East-West trending canyon and alluviated drainags courses descending from the South. Natural slope surfaces vary to as steep as 1:l (over local areas), with more gentle slope surfaces occurring near the ridge tops. Total relief within the property is on the order of one hundred and fifty (150.0') feet to tbres hundred and forty (340.0') feet above sea level. Site configuration is also depicted on the accmpanying site plan. Due- to discrepancies between the present and fonnsd topographic maps, ws suggesttopqraphybs checked. EXtTHMATSRIAIS Earth mterials consist primarily of alluvi~colluvi~ topsoil, artificial fill and bedrock. Alluvi~colluvi~ consists of dark brown silty sands and silty clays. Topsoils consist of dark to light brawn silty sands derived fmn weatheringofthe underlying bedrock. .--I-., T.rs-..-r#-l ..,.,-.A, PALlPl IITALITC llr,P MADISONSQUARE PAPTNSPSHIP -3- W.O. 4422 GEDLCGIC SETPING The project area is underlain by the Socene De1 War Formation (Tdts). This unit is manteled by alluvia, fill, topsoil and terrace deposits. The sedimantary bedrock materials observed on-site are generally gray- white, cross-bedded to massive sandstone. Aseguence of interbedded rusty-gray sandstone and green-gray marine siltstone-claystone occur within the site. Regional dip is approxirrately five (5") degrees to ten (10') degrees to the Worth. Localized folding as well as cross-bedding has resulted in local variations which could affect cut slope stability in sum cases. An ancient landslide ccaplex is present within the property. The approximate extent of these slides are outlined on ths attached geotechnical xkap. There are two (2) prevailing joint patterns: North by North-West and East- West which may play a role in the stability of North-West facing cut slopes. Capping the De1 War Formation at the higher elevations (300f) is the Quantemary Linda Vista Formation (QLvc) which consists of brownish to red sandand gravel terrace deposit. Alluvia (QAL) is present on ths site in minor aunts within the lessor North-South alluviated drainage courses and consist of dsrk brown silty clayey sands and silty clays. Fill (Af) on the site ranges in thickness to twenty-seven (27.0') feet and was placed in 1982-1983 under the observation of ACIICN ENGINEERIffi :CONSULTAW!?S, INC., Anaheim, California. The fill materials are derived frcan on-site borrow areas consisting of alluvium and De1 War Formation. Ground water was not observed during the exploration, however, minor seeps were encountered along clay searm within the ancient slide. Soil materials are further described on the attached Test Pit Logs. CCWCLUSICNS ANU PECCMENDATICNS Uevelopnrsnt of the site as proposed is considered feasible fran a soils engineering standpoint provided that the recamendations stated herein are .n.n., ,-n-T\T.-PI l.llPAl PT\*,cm oIT**n-c Iklr- -4- W.O. 4422 incorporatedinthe design andare inpleamted in the field. GRAUING REXWENDATIONS All existing vegetation shall bs stripped and hauled fran the site in accordance with the attached "Specifications for Grading'. Existing fills, alluvia andweatheredbedrock materials are readily excavatable with conventional earth wing eguipnent. H-V realatively unweathered bsdrock units my require ripping. Overexcavation and reccepaction beneath the proposed buildings will be required. -- Scm of the proposed buildings straddle an existing cut/fill line. -- For the buildings which are to rest partially on fill and partially on cut, either: a. Overexcavated seven (7.0') feet and reccmpact the foundation areas which lie in cut. Excavation should extend a minimm lateral distance Of five (5.0') feet measured from the outside edge of footings. b. Use belled caissons and gradebeam to support the portion lying over fill. A safe bearing value of 2,000 psf. my be used in design. -- The upper two (2.0') feet of the existing fills will require reprocessing. The stability of the existing cuts in part of Lots 13, 14 and 15 do not possess the minti required safety factor of 1.50. In ordertoprovide an adequate factor of safety in the cut slopes a shear key aud buttress is recamended. The specifications for the buttress/shear key are provided in Plate , cross-section A-A' and Geologic Map contained in Appendix B. Cuts as proposed will range in height from thirty (30.0') to forty (40.0') feet. Buttress key widths and depth have been calculated for these slopes APIIC.., PrT\Tl-PII.llPA, PA*ICI IITA*ITC IkIn- MADISONSQJAFE PARTNERSHIP -5- W.O. 4422 and shall be forty (40) and five (5) respectively. -S SUPDRAINS Subdrain systems should be installed at the rear of all buttress and stabilisation fills as shown on Plates A and B, Appendix C. STABILITY OF MKCUTS Cwing to the in&rent weakness of slide/materials along slipplaues, it is possible that during construction of buttresses or shear keys, failures may occur within the excavated temporary backcuts. Ifthiscccurs, the slide materials will have to be removed and replaced with ccapacted fills. It my also bs necessary to construct sm of the largsr buttress in sections or to lay back cuts at a shallower angle. All grading snd/or foundation plans shall be reviewed by ths Soil Engineer. The proposed structures shall be supported by continuous only spread footings placed a minimm depth of twenty-four (24.0") inches below lowest adjacent finish grade utilizing a recamended safe bearing value of 2,000 pounds per square foot. This value is for deadplus live load andmaybe increased by l/3 for total including seismic and wind loads whsre allowed by code. Increases in bearing capacity for increases in footing dimnsions are tabulated below: Ta.?. Mill- Minimum Bearing Increase oepth Width Value W&mm Depth Width (inches) (inches) (Pf) (psf/ft)(psf/ft) Continuous 24 12 2,000 333 500 3,000 Prior to placement of any concrete or steel, the bottomof footings shall be observed and approved by the Soil Engineer. KKPANSIVS SOILS Results of expansion tests indicate that the near surface soils have a low to high expansion potential. The high ret-ndations on the MADISCNS~ARE PARlWSRSHIP -6- W.O. 4422 acccspauying Expansive Soil Rewmnsndations, Plate C, should be considered in design of foundations and slabs. Final design should be based on expansion tests at the cmpletion of grading. The rmximm anticipated post-construction settlement is estimated to be on the order of l/2". Differential settlements are expected to be less than l/4". measured between adjacent structural elements. SIJESIDENCS ANDSHRINKAGS Subsidence over the site is anticipated to be on ths order of 0.1 feet. shrinkage of reworked materials shouldbe in the range of five (5%) percent. LATERAL DESIGN Lateral restraint at the base of footings and on slabs may be assmad to be the product of the dead load and a coefficient of friction of 0.35. Passive pressure on the faceof footingsmayalsobe used to resist lateral forces. A passive pressure of zero (0) at the surface of finished grade. increasing at the rate of 300 pounds per square foot of depth to a mxinim value of 3,000 pounds per square foot may be used for natural soil and catpacted fill at this site. If passive pressure and friction are cmbined when evaluating the lateral resistance, the value of the passive pressure should be limited to 2/3 of the values given above. FImR SLAPS Slabs on grade should be designed according to recamendations for high expansive conditions, as shown on Plate C. Care shouldbe exercised to ensure that reinforcement is placed in the center of the slab. The soil should be kept moist prior to casting the slab. However, if the soils at grade becans disturbed during construction, they should be brought to one hundred and twenty (120%) percent over optimm moisture content and be rolled to a fim, unyielding condition prior to placing concrete. In areas where a moisture sensitive floor covering will be used, a vapor APTBALI PrATrPl I.IIPAl c-T\klCl rITA*ITc l\lP MADISON SpUAF!E PAFdWEPSHIP -7- W.O. 4422 barrier consisting of a plastic film (6 mil polyvinyl chloride or equivalent) slmuld be used. The vapor barrier shouldbe properly lapped and sealed. Since the vapor barrierwillpreventmisture fran draining fran fresh concrete, a better concrete finish cau usually be obtained if at least two (2.0") inches of sand is spread over the vapor barrier prior to placement of concrete. UIILITY LINE mxPILLS It is ret-nded that backfills placed belaw and within five (5.0') feet of buildings and below asphalt concrete pavems nt and portlaud -nt concrete flatwork be compacted to at least ninety (90%) percent of maximsa density. Backfills placed in other areas to bs landscaped need only to be cmpacted to eighty-five (85%) percent of maximm density. All backfills require testing at two (2.0') foot vertical intervals during placement. ENGINEERING CcNsuLTATIONS, TESTING AND INSPECTICN We will be pleased to provide additional input with respect to foundation design once mthods of construction and/or nature of inported soil has been determined. Grading and foundation plans should be reviewed by this office prior to c-ncement of grading so that appropriate reccmaandations, if needed, can be made. Areas to receive fill should be inspected when unsuitable materials have been r moved and prior to placement of fill, and fill should be tested for :-action as it is placed. GENEBAL INFDFMATION This report presents re cumendations pertaining to the subject site based on the assmption that the subsurface conditions do not deviate appreciably from those disclosed by our exploratory excavations.

PREPARATION After the foundation for the fill has been cleared, plowed or scarified, it shall be disced or bladed until it is uniform and free from large clods, brought to a proper moisture content and compacted to not less than ninety (90%) percent of the maximum dry density in accordance with ASTMxD-1557-70 (5 layers - 25 blows per layer; 10 lb. hammer dropped 18": 4" diameter mold). MATERIALS On-site materials may be used for fill, or fill materials shall consist of materials approved by the Soils Engineer and may be obtained from the excavation of banks, borrow pits or any other approved source. The materials used should be free of vegetable matter and other deleterious substances and shall not contain rocks or lumps greater than eight (8") inches in maximum dimension. PLACING, SPREADING AND COMPACTING FILL MATERIALS Where natural slopes exceed five (5) horizontal to one (1) vertical, the exposed bedrock shall be benched prior to placing fill. The selected fill material shall be placed in layers which, when compacted, shall not exceed six (6") inches in thickness. Each layer shall be spread evenly and shall be thoroughly mixed during the spreading to ensure uniformity of material and moisture of each layer. Where moisture of the fill material is below the limits specified by the Soils Engineer, water shall be added until the moisture SPECIFICATIONS FOR GRADING PAGE 2 content is as required to ensure thorough bonding and thorough compaction. Where the moisture content of the fill material is above the limits specified by the Soils Engineer, the fill materials shall be aerated by blading or other satisfactory methods unit1 the moisture content is as specified. After each layer has been placed, mixed and spread evenly, it shall be thoroughly compacted to not less than ninety (90%) percent of the maximum dry density in accorcdance with ASTMID- 1557-70 (5 layers - 25 blows per layer; 10 lb. hammer dropped 18" inches: 4" diameter meld) or other density tests which will attain equivalent results. Compaction shall be by sheepsfoot roller, multi-wheel pneumatic tire roller or other types of acceptable rollers. Rollers shall be of such design that they will be able to compact the fill to the specified density. Rolling shall be accomplished while the fill material is at the specified moisture content. Rolling of each layer shall be continuous over the entire area and the roller shall make sufficient trips to ensure that the desired density has been obtained. The final surface of the lot areas to receive slabs on grade should be rolled to a dense, smooth surface. The outside of all fill slopes shall be compacted by means of sheepsfoot rollers or other suitable equipment. Compaction operations shall be continued until the outer nine (9") inches of the slope is at least ninety (90%) percent compacted. Compacting of the slopes may be progressively in increments of three (3') feet to five (5') feet of fill height as the fill is brought to grade, or after the fill is brought to its total height. Field density tests shall be made by the Soils Engineer of the compaction of each layer of fill. Density tests shall be made at intervals not to exceed two (2') feet of fill height provided all layers are tested. Where the sheepsfoot rollers are used, the soil may be disturbed to a depth of several inches and density SPECIFICATIONS FOR GRADING PAGE 3 readings shall be taken in the compacted material below the disturbed surface. When these readings indicate that the density of any layer of fill or portion there is below the required ninety (90%) percent density, the particular layer or portion shall be reworked until the required density has been obtained. The grading specifications should be a part of the project specifications. The Soil Engineer shall review the grading plan prior to grading. INSPECTION The Soil Engineer shall provide continuous supervision of the site clearing and grading operation so that he can verify the grading was done in accordance with the accepted plans and specifications. SEASONAL LIMITATIONS No fill material shall be placed, spread or rolled during unfavorable weather conditions. When work is interruped by heavy rains, fill operations shall not be resumed until the field tests by the Soils Engineer indicate the moisture content and density of the fill are as previously specified. EXPANSIVE SOIL CONDITIONS Whenever expansive soil conditions are encountered, the moisture content of the fill or recompacted soil shall be as recommended in the expansive soil recommendations included herewith.
