Bedding typically strikes to the north and dips gendy to moderately to the east, consistent with our previous findings. The siltstone is dghtly folded and sheared in the central portion of the excavation. A small wedge type failure has fallen into the bottom of the excavadon on the western wall within this sheared zone. The geologic structure mapped within the excavadon is shown on the Geote�hnical Map. The geology exposed in the excavadon is consistent with our previous findings and our previous recommendations rerr�ain valid. The opportunity to be o£service to you on this proje�t is appreciated.

Item 5 Temporary cuts are on bedding planes and will nat create daylighted bedding which would require analysis. See sections. All new grading will produce fill slopes due ta slide removals and replacement with compacted fill. All slapes (fill) will be at a ratio of 2 : 1 or flatter. The grading is not considered remedial. Regarding the locatian of the Restricted-Use-Line, see aur comments under Item 5. Item 6 The location of the "headscarp" of the landslide and the Restricted-Use-Line do indeed cross near the south property line of lot 21. This location was taken from data by Robert Stone and Associated dated December 21, 1970 and referenced in our report dated March 18, 1997. This data was plotted on the grading plan dated January 27, 1997, which was part of our March 18, 1997, report. Our review letter dated July 14, 1997, reviewed a revised grading plan dated June 23, 1997. The "headscarp" was accurately transferred onta the map from the January 27, 1997, map, hawever, the Restricted--Use-Line was nat transferred. The existing pool is outside the "headscarp" and the Restricted-Use-Area. The pool house (a non-habitable structure) appears to be outside the restricted-use-area. 2 r - A she�� k�� was place� a� �he ed�� o� th� pad vn 1�� �� ta r�nder i� � bui1���I� site �St�n�� r�p���� dat�d �ecez�ber 2�, ����j . �'h� ��opo��� g����ng on l�t �� w��� r�m�ve most of �h� 1a�dslide �a�e���l ���t�r�y �f the ���1 h�u��. � smal� ��dge of "��ndslid� debr�s� und�r th� gool hou�� ��u1d p�s��bly r��ain.

Continuous foot�ngs should have minimum re2nforcement af two Number 4 bars placed near the top of the footing and Number 4 bars near the bottom Lateral Resistance Resistance to honzontat forces on foundations may be pro�ided by the combined effect of passive soil pressures and fnctional resistance be�ween concrete and firm soi�s. Lateral soil pressures of 25p pounds per square foat per foot of depth may be used up to 1500 pounds per square foot. A caefficient of fric�on of 0.3 is recommended for the on-site earth materials. Floor Slabs• Concrete floor slabs may be supported by the bedrock or compacted fi�� 50115. To provide uniform support, the top 8 inches of soil should be scanfied and compacted at near opt�muFn moisture cond�tion Due to the moderate expansive potential of the on-site soils, it is recommended that the top 18 inches have a moisture content above op�imum condLtions established 24 hours pnor to pouring the concrete. SZabs should have a minimum thickness of 4 inches and reinforcement of 6 x 6 - W2.9 x W2 9 {6 x 6 - 6/6) welded �vire mesh, or equ�valent, placed at the center of the slab For moisture sensinve floors, a vapor barner membrane covered w�th a minimum 2 inches of clean sand should be placed below the slab , 9 A grade bearn 12 i�ches by 12 in�h�s should be provided across �h� gaarage �ntrances.

If the landslide was recent or the existing safety factor is 1.0, the removal would likely cause movement of the slide. In this case, the landslide is an ancient slide that should be well healed and the existing safety factor is likely to be well above 1.0; however, proof would be difficult to establish accurately. It should be noted that if proposed grading proceeds before the end of the winter storms, this movement will be a greater possibility. t The landslide is a relatively shallow slide with a low angle of the slide plane. In the event that movement does develop, it will be a slow creep and not dangerous to personnel performing the grading. The limits of the slide are shown to be just outside the pool shell ; therefore, movement of the slide during construction should not damage the pool. The limits are shown to be inside the pool equipment shed and this structure could be effected. . 2 � �,�__._ - `� 3 - � � � � � � - - _ ... -- �7za�os�_� - � �Ec_tC!N f Ror�aSET� I7Rcr�aSEtj .$7-2JcTvfL� � �Rc3t�o5�� ���E<rI1/Cr ��.aqL � Sf�� �rfLKL.JA� � � `�O J ^ � � �Q� - - - . � `` , � ` - � � ` ~ ' �� � ` ` � ` QQ ` \ - - �J - - - � ` � �- � � � �r��r�a5� 7r�NNJS �oc.�2T � I� � i � 1 �� � � �- — I � ` � , ~ � � �I 6a ' � � T/� � � � � � � _ � �o _ � � � � � � .

The 2:1 portion of the proposed fil.l, on Lot 20 is now 22 feet high instead of 30 feet as before. On Lot 21, the 2:1 portion is about 29 feet high, roughly the same as before. 3. Drainage of both lots will now be conducted to a paved down drain near the lot boundary, then to a flex block sheet flow dissipator to be constructed on the natural slope below the toe of the new fill. CONCLUSION This new plan is feasible from a geotechnical standpoint, provided the recommendations contained in the referenced report are followed. These recommendations still remain valid for the project. _ Based on available data, and the grading plan having the revised date of June 23, 1997, the site will be safe against hazard from landslide, slippage or settlement. The proposed construction will have no effect on the geologic stability of property outside the build3ng area. 2 r , , Please contact us at your convenience if you have any questions regarding this report.
