C`UE 2050489.05 Januaiy 4, 2007 Page 4 �'ILL SLOPE AIVI3 I�EEYWAY�: Keywa��s �veie ezca�Tated along the toe of the fill slopes at the eastein aiid �vestein edge of the site. The key��a5� excavation eYtended into the competent native mateiial, and �vas configuted to dip slighdy to��asds its heel of the key. The key�vay extended appiozimately 1.5 to 2 feet into competent foimational mateiials and �vas appio�imately 20 feet �vide. The soils ezposed at the flooi of the key�vays �veie scarified to a depth of 12 inches and moistuie conditioned pxioi to fill placement. Fill mateiial consisting of the on-site silt�� sands weie dien placed as desciibed in the pieceding `Fill Placement' patagiaph. 1�s the elevation of the fills incieased, horizontal beuches weie eticavated into the foimational materials. FILL PLACEP/�E1VT: Fill mateiials consisting of the on-site silty sands weie typically placed by the sciapeis and cxawlei dozers in ielativelp tl�in, unifoim lifts. IVloistuie conditioning was applied as needed and compactive efforts weie then perfoimed by ineans of the �vheel dozeis to at least 90 peicent oF inaYitnum diy deusity. RETAINING WALLS FOUNDATION OBSERVATION: Piioi to the pioposed consttuction of dle ietait�ing walls, die foundations eYcavations foi the walls weie obseived by a representative of oui firm. The eticavations �veie found to eYtend 'uito competent bearing stcata. GENERAL: Foui retainiiig �valls �veie consttucted at die subject site. The walls aie located between Lots 3 and 4, along the iear yaids of Lots 5 tlitough 7, between Lots 16 and 17, and bet�veen SongUiid Avenue and Lot 16. The Letainisig ��alls �veie `Allen Block' type reinforced eaith, segmental block �valls. Representatives fiom oux office observed the constiuction of the ietaining walls, the placement of the geogrid reinfoicement and the placement and compaction oE the backfill soils. SUBDRA.INS: Preceding d1e backfilling of flle ietaii�ing tvalls, subdiains �veie installed at the base of the walls. The subdiains consisted of a foui-inch diametei peifoiated PVC pipe set in a matrix of ciushed iock, wiapped �vith geotechnical filtei fabiic. WALL BACI�FILL: The foui ietaining walls �veie backfilled using native sandy soils. The baclifills weie placed ui thin hoiizontal lifts, wliich weie wateted to neax optimum conditions and compacted in place to at least 90 peicent of znasunum diy densit�� by means of the iecipiocating compactors. C�UE 2050489.05 Janu�y 4, 2007 SITE IIVIPROVEMENTS Page 5 Our field iepresentatives peifoimed peiiodic obseivations of tsench backfill foi wet and diy utilities as well as the piepuation of subgiade and aggiegate base couise mateiials and subsequent asphalt conciete placement in the road�va5�s. In geneizl, flle utilit�� tiench backfill opexations consisted of soils being placed in tl�in unifoim lifts, moistuie conditioned with a �vatei tiuck and compacted to at least 90 peicent of the malimum diy density. The subgtade piepaiations consisted of ininoi cuts and fills to designed giades, �vith die soils being scarified, moistuie conditioned and compacted to 90 peicent of die maumum diy densit�T foY areas of pioposed sidewall�s, and 95 peicent of maYimum diy density foi paved aieas. t�ggiegate base couise materials �veie placed in thin, unifoim lifts, moist�iie conditioned and compacted by means of dual di�um vibiatoijT compactois to at least 95 peicent of dze ma�num diy densit�T. Asphalt conciete placement was motutoied foi tempeiatuie duiing laydo�vn opeiations. The contractar peifoimed compacti�Te effoits of the asphalt conciete using smooth dium vibiatoi5� compactoxs, as well as a pneumatic tiie coinpactor, to attain at least 95 peicent xelative compaction. FIELD ANl� LABORATORY TESTIIVG FIELD TE�TS: Field tests to measuie the ielative compaction of the fills, backfills, subgiade, aggiegate base couises and asphalt conciete, weie conducted in accoidance �vith ASTl��I Test Designation D 2922-91, "Standaid Test Methods foi Density of Soil and Soil-Aggiegate in Place by Nuclear Methods," and ASTNI Test Designation D2950-91, "Test Method of Bituminous Conciete in Place by Nucleai Method." The locations of the field tests �veie selected by ow' technicians in aieas disceined to ezhibit a degxee of ielative coinpaction that �x�as geneially iepiesentative of dlat achieved in flie backfills, subgiade, aggiegate base course and asphalt concrete placeinent. The iesults and appiozimate locations of tlie field tests aie sho�vn on the attached Plate Nos. 1A tlitough 5. OUTSTANDIIVG LOW COMPACTION RE�ULTS: Oui secoids indicate diat theie aie ateas that contain `test iesults Uelo�v the iecomtnended ielative compaction of 95 peicent of ma�num dxy density. These iecoids show that tlitee stteet subgiade, si.z ctub and guttei base, and nine asphaltic conciete tests indicate low compaction �vidl no ietesting peifoimed. Though not necessatily indicative of potential pioblems that could occur �vith low compaction, otu office cannot veiif�T tlzat these aieas were xewoiked and/oY iecompacted to iecommended values. T�venty tests weie iecoided tluoughout flie aieas that weie paved witll asphalt concrete duruig d�is phase of the paving. Of tliese tests, nine tests ��eie above 95 peicent ielative compaction, 5 weie in the 93 to neai 95 C`�1E 2050489.05 Januaiy 4, 2007 Page 6 peicent iange and 4 test was below 93 peicent, but gieatei than 91 peicent. It is oui opinion diat the maiginally low densities iecoided in the asphaltic conciete shot�ld not have a significant effect on the peiformance of the pavement. Elperience has sho�vn fliat unit �Ueights pioduced bjT asphalt cores taken aie t��picallST highei than the �ralues pioduced in the field by the nucleat gauge method. If ietesting is necessaiy, we suggest diis method be utilized. T ARORATORY TE�TS: The maY'ttnuin diy density and optimuin moistuie content of the soils piedoininately encounteied in the eaidlwoik ��eie pexfoimed in oui laboiatoiy U�T ASTIVI Test Designation D 1557-91, "Test Nlethod foi Laboratoiy Compaction Chaiacteiistics of Soil Usu1g l��Iodified Effoit." The tests ��eie conducted in accoiduice with the mediodology piesciibed foi the giain-size distiibution of the soils tested. The iesults of these tests aie piesented on the attached Plate Nos. 14 and 15. Repiesentative samples of the soils piesent within dle foundation zone of the pioposed stcuctures weie tested foi thev- eYpansion potential in accoidance �Uith ASTI��I D 4829-95, "Standaid Test Method foi Etpansion Indel of Soils" and for theie sulfate content in accoidance with Caltrans l�Iethod 417, "1Vlethod of Testing Soils and Wateis for Sulfate Content." These test iesults aue also piesented on Plate No. 15. CONCLUSIONS GENERAL: It is the opinion of Cliristian Wheelei Engineering that the giading addiessed by tlus ieport has been peifoxmed in accoidance with the iecommendations piesented in the iefeienced geotechnical iepoit, the giading iequirements of the City of Cailsbad and dle Unifoim Building Code. This opuuon is based upon out obseivations of the eaithwoik opeiations, the iesults of the density tests taken in the field, and the ma:�imum density tests peifoiined in oux laboiatoiy. It is oui fuither opinion that the site is suitable foi the pioposed construction. Oui iecominendations foi the ininitnuin design of foundations foi the pioposed st�:uctuie, based on the as-giaded conditions, aie piesented in the "Foundations" section of this iepoit. Based upon the field and laboiatoi-�T tests, it is otu opinion diat, �vith the eaception of the areas iepresented by the afoiementioned lo�v compaction test iesults, the suUgiades, aggiegate base couises and asphalt conciete pavements �veie placed and compacted in accoxdance with ow- iecomtnendations, and the Uniform Building Code. AS-BUILT GEOLOGY: The geologic units encounteied during die eaxthwoik opexations weie geneiall�T consistent �vith those anticipated in oui iefeienced iepoit of geotechnical investigation. The e�udl�voik C��i�E 2050489.05 Januaiy 4, 2007 Page 7 opeiations addiessed by tliis iepoxt have, in oui opinion, satisfactoiily initigated the potentially adveise conditions described in die iefeienced iepoit. FOUNDATION RECOMMENDATIONS GENER_AL: It is oui opinion that the pioposed stsuctuie may be suppoited by conventional continuous and spiead footings. Specific details foi the design of the foundations should be piovided bj� the stiuctuial engineei foi the pioject; howevei, the foundation design should incoipoiate dle mit�iinum iecoinmendations piesented in tlle follo�ving paiaglaphs. EXPANSION CI�ARACTERISTICS: The soils piesent �vitivn die zone of influence of the pioposed foundations aie consideied as being non-dettimentall3T ezpansi�7e, �vith an eapansion index less than 50. The iecoimnendations piesented heiein ieflect tlus condition. CONVENTIONAL FOUNDATION�: Conventional spiead footings suppoiting the one- and t��o-stoip single-fatnilST iesidences should be emUedded at least 12 and 18 inches belo�v finish pad giades, iespectivel5�. Continuous footings foi one- and t��o-stoiy sttuctures should have a minimum �viddi of 12 and 15 inches, iespectivel��. Isolated footings should have a minimum �vidth of 24 inches. BEARING CAPACITY: Conventional footings �vith the above recommended minimum ditnensions ma�� be designed for an allowable soil beaiing piesstue of 2,500 pounds pei squaie foot. Tliis value ma�� be incieased by one-tlu�:d foi combinations of tempoiaiy loads such as fllose due to wind oi seisinic loads. FOOTING REINFORCIlVG: Based on the as-giaded soil conditions, �ve iecommend that the rniniinum leinfoicing foi continuous footings consist of at least one No. 4 bai positioned tiv:ee uiches above die bottom of the footing and one No. 4 bai positioned t�vo inches below die top of the footing. Tlus ieinforcement is based on soil chaiacteiistics and is not intended to be ui lieu of ieinfoicement necess�uy to satisfy stcuct�ual consideiations. LATE1tAL LOAD RESISTANCE: Lateial loads against foundations may be iesisted b�� friction between the bottom of the footing and the suppoiting soil, and by the passive piessuLe against fl1e footing. The coefficient of .friction bet�veen conciete and soil map be consideied to be 0.35. The passive iesistance may be consideied equal to an equivalent fluid �veight of 250 pounds pei cubic foot. Tl1is assumes the footings ale pouied tight ag�ist undistuibed soil. If a combination of die passive piessuie and friction is used, fl1e fiiction value should be ieduced by one-d1'v:d. CWE 2050489.05 Januai-�� 4, 2007 Page 8 SE'I'TLEMENT CHARACTERISTICS: The anticipated total and diffeiential foundation settleinent is ezpected to Ue less than about 1 uzch and 1 uich ovei 40 feet xespectivelp, piovided die ieconunendations piesented ui this ieport aie follo�ved. It should be iecognized fllat minoi ciacks noimally occur in conciete slabs and foundatioris due to shtinkage duiing cuiing oi iedistiibution of stiesses, tl�exefoie some ciacks should be anticipated. Such ciacks aie not necessaiily an indtcation of excessive �Teitical movements. FOOTII�tG SETBACI�S: If footings foi structuies aie pioposed adjacent to the top of slopes, tve xecommend diat a minimum hoiizontal setback fiom the outei edge of the footing to the adjacent slope face be piovided. The miniinum setback fiom die slope face recommended is 5 feet fiom slopes 0 to 15 feet high, 10 feet foi slopes 15 to 30 feet high, and 15 feet foi slopes ovei 30 feet. The building setback distance foi die top of slopes ma�� be inodified by using deepened footings. Footing setback is,measuied foim competent soil and should neglect any loose of soft nati�Te soils tlzat map occui at the top of a natuial slope. Footings planned undei the specified setbacks should be piovided specific ievietv by the Geotechnical Consultant piior to constiuction. FOUI�DATION OBSERVATION: In oidei to confiim that the footing eYcavations estend into a suitable beaiing sttattun and to verify dlat the footing dimensions and ieinfoicing steei schedules ue in accoidance with tlie miLvmum iecoinmendations piovided by the geotechnical engineer, Cluistian Wheeler Engineeiing should be contacted to obseive the eYcavations in advance of sttuctural inspections fl�at may be conducted oi iequited by the Building Official. ON-GRADE SLAS RECOMMENDATIONS INTERIOR FLOOR �I,ABS: The minimum flooi slab ducl�less should be not less than four inches. The flooi slabs should be xeinfoiced with at least No. 3 bais placed at 18 inches on center, each �vaST, and the ieinfoicement should estend hoiizontally at least 6 inches into flie footings. Slab ieinfoicuzg should be positioned on chaits oi moitax blocks at mid-height in d1e flooi slab. UNDER-SLAB VAPOR RETARDERS: Steps should be taken to minimize the ttansmission of moistute vapoi fiom die suUsoil tl�xough the viteiioi slabs wheie it can potentially damage the interioi flooi covexings. Local industty standaids typically include the placement of a vapor ietaidei, such as visqueen, between tzvo, 2-inch-tluck layeis of coaLse sand placed dixectly beneath the conciete slab. This is the inost common undei- s11b �Tapoi ietaidei system used ui San Diego County. The vapoi ietatder should be at least 15 inil visqueen ��ith sealed seams and sliould eYtend at least 12 inches do�vn the sides of the inteiioi and peiimetei footings. C�UE 2050489.05 JanuaiST 4, 2007 Page 9 The sand should contain less than 10% passu�g the numbei 100 sie�Te and less than 5% passing the numbei 200 sieve. Although dle spstein desciibed above has liistoiically peifouned adequatel�T, national standaids foi d�e uistallation of vapoi ietaideis belo�v 'viteiioi slabs aie changing as evidenced iu cuiiend5� published standaids including ACI 302, "Guide to Conciete Flooi and Slab Consttuction" and AST1��1 E1643, "Standaid Piactice foi Installation of Watei Vapoi Retatdei Used in Contact with Eaid1 oi Gianulai Fill Undei Conciete Slabs". Radiei than placing the vapoi ietaider bettveen the two sand la5�ers, bodi of these standaids iecommend placing the sand capillaip bieak laSTer onto the subgiade �vith a vapoi ietaidex placed above the sand and tlie conciete placed dii:ecdy onto the vapoi ietaidei. Theie aie advantages and disadvantages to each of these installation piocedtues. An advantage to placulg conciete ditectly onto a vapoi ietaidei is that it eliininates dle layei of sand bet�veen the slab and vapoi ietaidex. Tlvs layei of suid t��pically contains moist�iie pxioi to die placement of conciete and can ieceive moie moistuie duiing the cuiing and constsuction piocesses. This moisture can be ietained in the sand layei fot an etitended peiiod of time until the conciete moisttiue decxeases to the point at which the excess sand moistuie is absoibed by the conciete and tcansmitted up tiv ough the slab. Tlvs piocess can take many months dependu�g upon die enviiomnental conditions. One disadvantage to placing conciete diiectly onto a vapoi ietaidei is that iemoving die sand layei fiom diiectlST beneatli the conciete iestiicts die ability of the conciete to lose moistzue on both flie top and bottom sw'faces duiing the initial ctuing peiiod. Vatiations ui flie diying rate bet�veen die top and bottom surfaces can iesult in incieased conciete ciacking, cuiling, and othei fuiisliing issues. The diying rate diffeiences and theit potential side effects can be iz�itiiinized, hotvevei, widi suitable finislvng and cu�ng pioceduies. Recognizing the stated benefits and 1'vnitations of these standatd belo�v-slab vapoi retaider systems, the o�vner and designei should select the system that they believe is inost suitable foi this pioject consideiing the const�uction schedule and planned flooi coveiings. It should be undeistood that neithei of the desciibed sj�stems piovides a"��ateipioof baiiiei". It should also be undeistood that slab conciete contains fiee �uatei and should be allowed to xeach equilibrium in an envu'onment similai to that anticipated in die completed structuie piioi to installing flooi co�Terings. We iecommend tl�at the flooiing installei peiform standaid moisture vapoi emission tests piioi to the installation of all moistuie-sensittve flooi co�Teiings in accoidance with ASTNI F1869 "Standaid Test Nlediod foi l�Ieasuiing NloistuLe Vapoi Einission Rate of Conciete Subflooi Using Anhydious Calcium Chloiide". C� 2050489.05 Januaiy 4, 2007 Page 10 EXTERIOIZ COIVCRETE FLATWORI�: Ezteiioi slabs should have a riiin.imuin tlucl�iess of foui inches. Reinfoicement and conttol joints should be constiucted in ezteiioi conciete flatwoik to ieduce the potential foi ciacking and movement.
