of construction to help insure all individual structure footing foundations bear on like
materials with suitable strength and low volume change potential. The near surface site
lean clay or properly placed and compacted fill and backfill could also be used for direct
support of exterior flatwork and site pavements. Other opinions and recommendations
concerning design criteria and construction details for the proposed site improvements
--- are included with this report.

Mr. Derbes:
Soilogic, Inc. (Soilogic) personnel have completed the geotechnical subsurface
exploration you requested for the proposed duplexes to be constructed at 712 West Laurel
Street in Fort Collins, Colorado. The results of our subsurface exploration and pertinent
geotechnical engineering recommendations are included with this report.
In summary, the subsurface materials encountered in the completed site borings consisted
of a thin layer of topsoil and vegetation underlain by light brown to light reddish brown
- lean clay with varying amounts of silt and sand. The lean clay showed low volume
change potential with variation in moisture content at in situ moisture and density
_. conditions. The lean clay extended to the bottom of boring B-3 at a depth of
approximately 10 feet below ground surface and to depths ranging from approximately
12 to 13%2 feet below ground surface at boring locations B-1 and B-2. At boring
locations B-1 and B-2, the lean clay was underlain by clayey sand and gravel. The sand
and gravel was dense and extended to the bottom of boring at a depth of approximately
15 feet below present site grads. Groundwater was not encountered in any of the
completed site borings at the time of drilling.
Based on the subsurface conditions encountered, results of laboratory testing and type of
_. construction proposed, it is our opinion the proposed buildings could be constructed with
conventional footing foundations and floor slabs bearing on natural undisturbed lean clay
with low swell potential and/or properly placed and compacted fill and backfill. Careful
evaluation of the proposed foundation bearing materials should be completed at the time
