RE: 9a2' & 6~5 Glacier. Snrinafield - W.o. #6484-RDR
Ag you requested, a site inspection was performed to determi,ne t'r..,
6uitability of the lots for placement of conventional wood fr.'lln(,-:l
single family dwellings on concrete foundations. Based on site "ne:
soil conditions, I make the following recommendations:
At 6893 Glacier, a minimum of 12" of compacted crushed rock is t.;
be placed on the building site.
At 46~~S Glacier, an additional lift of crushed rock is to Ice
placed on the site to bring the minimum depth of crushed rock to
12". '
At both sites, the attached "Procedures" are to be used as a
guideline for placement of the crushed rock.
I hope you find this report adequate for your purposes at this time.
Please contact me if you have Thank you for thi~
opportunity to be of service.
Enclosure: "Proc~dures"
Very truly yours,

Tbe following procedure can be used with the proper controls and materials:
1. Sit; r[Ct'~,"'inn' The site should be properly drained with no free water present, The surface should be capable
of supporting the equipment used without rutting or causing the existing soil to turn into mud dllc to the
operation of equipment. The site should be scalped of all vegetation 10 at least 8" . 12" below original ~"und
surface to extend at Icast 12" or the deplh of the fill beyond the perimeter footing line. Tbe subgrade sb0ujd
be at a uniform elevation with a maximum l' tolerance.
2, fill Malerial & Placement: The gravel or crushed rock fill material should be well graded with a sufficient
amount of roarse and fUle material to fill all voids when rompacted, The material should be free of silt,
overburden or other material which would react adversely to compaction or variations in moisture c<'nlent. The
fill should be placed by end dumping and bladir.g in a manner to prevent separation of rourse and fine materials,
Placement ~ho\.lld be in maximum 6" deep lift) wirh wUlpactiou accolUplblH;d ~u tb~ ~Urr'H.:C uf each layer

foundation of any building or structure shall be placed in accordance with accepted engineering prHcrke, A soils
investigation report and a report of satisfactory placement of flll, both acceptable to the Buildlng Official, shall
be submitted". To comply with this requirement, the following procedure is recommended:
a, Engineer is to lnspect and approve site prior to any excavation or grading being perfurmed.
b, Engineer is to make any additional or special rerommendations for modification of the above
procedures based on specific site conditions.
c, Engineer is to inspect site during the subgtade excavation and preparation.
d, Engineer is to Inspect site during or after completion or the fill placement,
e, Engineer \s to provide report of compliance with this procedure and verification of satisfactory
soil bearing for the proposed structures,
