Dear Commissionens:
I wish to enlange the building envelope on Iot #2 Cottonwood Hollow
Suhdivision in order to allow an elongated "Solar ef f icient" design. Also,
the house nestles into the side of the hill and will r'equlre deep excavation
at the rean of the "walk out" downstairs, The presence of extremely lar'ge
bouldens may necessitate shifting the house to avoid immovable nock, Thank
you for^ your attentlon on thls matter,
Yours sincerel

Gent leuen,
As requested, Irincoln*DeVore personnel have recently coupleted atest Pit excavation evaluatlon at the above referencedl site todtteruine the condition of the foundation bearing roils. Our
concluaiona and reconhendlatlonr for the ciLe are presented below:
EgiI ElaeSif,iqaiieni fhe soils on thir slte are qulte varlablerranging fron aoattered cobbles and gravels in a low plastic claynatrix in the upper 2-l/2 feet to a nedlua to largc bouldera ln avery sandy clay natrix. These soils have low expansiveptoperties. Thc allowable hearing capacitiea of the soilr are
2600 pef maximum and {00 ptf niniuutr,
UaU=pa0S Etlli The soils encountered in our teat horinga appearto be native to the aite. Ill building foundlations nust penetrate
any [an-nade fills which are present at the aite at thlc tlne, aswell aE eny fills t{hich rerult frou the excavaLion process.Carefull examlnatioD of the open etccavationtrill be necessary todetermine' the ptesencc or abaence of man-made fillg. The opene*travation nuat be exauinedl prior to the placenent of concrete toe8tabliEh that fiaterials of, proper detlgn bearlng oapacity have
becn exposed aud.'that no toft spoti or ilebrlE are present in thefoundatioa area, A 24 hour notice ,ls required f,or al l f ieldexanlnatlons to enable Lincolu-DeVore to cchedule persobnel andprovlde service when ueeded. ..

Eeun0aLisn Iygg EggqBEEu0Eli A properly designed shallowfoundation system based upon the above allowable soll bearlngtrtpatritiGt would be eppfoptlett for thla tlt!. Llncoln-DcVore hasnot been provided uith a set of coustruction drawlngc for thisstructure, therefore, we cannot provide precice foundatiou
