In the areas where soft till or alluvial clays <br /> and clayey sands will be exposed(such as near Borings#3, #4, #5 and#6),we recommend deeper <br /> ' excavation be performed to extend the excavation at least one footing width below the design <br /> footing grades. If the "Alluvium or Fill" and "Till or Fill" soils aze determined to be fill that was <br /> ' previously placed,they should also be removed from below building foundations. We recommend <br /> these soils be more closely observed and evaluated before filling to grade or constructing the <br /> ' footings. Anticipated minimum excavation depths and excavation bottom elevations for the <br /> footings are indicated in the following tabulation for the respective boring locations. <br /> � <br /> <::'y;>;::>:::`::;:::»:><`;:::>>:;:> <br /> ::>.<:;<:;:�::::;<:`::;:>:>:::::`:`` <br /> ,........ :.:::..:............. ..... <br /> :«;:«:>::.;�.;:;.:;:.; ..:.::.�:>:::.:::.:..:;::.:::.:-.:;::::::.::.,�.;-.:.. <br /> :::;::.:::::�.:::::.. ::.::::.:::::::::::»::::::.:..:...;:.,.:::;:,.;:.:...: <br /> .:......,.:...:.... .::.::,:...:..,....:.::..:...:::;. .. ..... <br /> .::>::�:>:>::::<<;:.::»»<>:>::»:::::»>:;;;::::;:.::;:>:<:>;:.: <br /> .......:::.::.::..:....>..::::._:,.;.:...:..::.....:..�:......... <br /> <:::;:::.:::.:::::::.:;:..::. <br /> ::»::;;::;:«.:»::;::.::;::.;:.:;::.;;::.;;::.;;;;;:;:.; <br /> :>::::>::>;::>::>::;:;.:..;;:; � .... :::>::>:<::<::;::;:::.::::.. :.:.:.<:<::<::<:::<:<::::;:::::>::»::. ........,.::::.,.:.. .�::::::.>:>.:�;<>:>. <br /> :..;<:; .,::,:..:,:.:.:..::...:::»»:::<:><::: <br /> :,::.;:.;:.;;;:::. . ::.;;:.:�.;:.::.:::.:::::.::.;:.;:.::£ .:::: : : <:�::.::,.;::.;.;:.:;.;::.:;.:�:::�..�.�.c+��t+t�:::::;<::<:;::>: <br /> ��:>< <br /> ..... ........ <br /> <:��•.:.. <br /> ;::��::<:>::><::<:::>:::;: <br /> >:� <br /> ' <br /> ?::::�i:::.::.»?>�:::::::�;'::>:::<:::::>:::; <br /> :;;:;;;:;;............... ... <br /> :.:......::.:::::::.:::::.:::::;.;:•.....:::•:::. <br /> :.:::.:...:....:.....:......:•...::.:::..::...:. <br /> .;;;:.;�.;::.;:;::::.::.;:<•;::<•;;;••:•:.»;;:::•>::;;:.:. <br /> .:::;;::::>::�:::»::��<:::>:���> : <br /> ;>a:::.>•.;:..;::::>::::::>:;<:::>::: :;<`:s>::»::•�>:.>:::;:.o-::.;:.::.;::.::,;•:::.;:;.::.;::;;.:.:::.::::::::..:::::.::::::::::::::::... <br /> �i:i?:iii:3ii:iiiiii:;�i°:i;;:i:%�':Yiii;:i:::i;_i:i:i�i:::i::::::::::?i::::?::r..>xiiii::::::i:;?:::•'•::::::i:::i:::;::::?:i:::?fi:::::::t::��'o;:::::::i;::::::::?::;��;:i::.:;;:::i•>x::::::4:::::::;::::i:::::i;i:::>:<.::::>:::�::.:;;::: <br /> .. . .:...�:.>::::.::.::.::::::. .. <br /> •.�.:::::.::. •a:::..:::::p .........v:.....,:::::f::;:.:?:i::Y:::;i:::::[<: :. .::.... r:� 'ik::.�'•: C<:':�i:5'S:::::::i:i;::? . <br /> ;::::.::;;:<.: • . ;;:::,;;;;:;.;:>::,•.;:;:>:: . .01�:>;»s>;>:::::>:>;>;:::�::>:.:::�L`:$Y�.:. .:. ;;;;;;::;;;::;;>:;,;;.�R'��::::::.,�:..:::::::.:. <br /> ::::>:>:>::::::>::�1�?�<::;:::::»<»:::>::>::>::::;;;���#i:.:::::::::.:::::::.:::::::.::,:.:.:::....:...............,...�.� <br /> ' 1 945.7 2* 9431fi* <br /> 2 945.7 4* 9411fi* <br /> , 3 . 946.0 4*� 942*� <br /> 4 948.0 6 942 <br /> ' g 948.9 6C� 941� <br /> ( 947.4 4*(c� 9431f�*� <br /> ' *_Indicases tytat the ^A1luvium or Fill"and "Till or F'r.11"soils ox these locations should be removed if it <br /> is determined that they are fi11.
