RE: Foundation design modifications for lot 58, Hayden Gardens
This is in response to your request for design assistance for the foundation at the above site.
The areas in question overlie a 24" deep stony fill (see attached report by Braun Intertec)
which was tested by and found to exhibit some deflections (reported to be "slight to moderate"
by Braun, 1/4" by George Arthur).
With the fill in place, it is not possible to determine the exact nature of the underlying soils. It
is safe to assume, however, that the deflections are the result of excessive moisture in the
underlying soils. This is probably due to the excessive rains experienced this winter. It is
also likely that some minor shrinkage of the underlying soils will occur when the water content
in the soils is reduced (by building coverage and by seasonal variations)
. We therefore have provided a design which would tie the garage floor slab to the footing and
stemwall, to keep all elements together in the event of slight movements. We do not
anticipate any noticeable structural problems as a result of the soils problems.
If you have any questions, please feel free to call our office.

Report
~';:,w~n""_"T'. _.,
Met on-site with Mr. Arthur (Hayden Enterprises) and Delta Sand & Gravel representative
to witness proof-roll on building pad #58. Was Informed by Mr. Arthur thot two (2) feet in
depth of native material was removed from the building pad limits and the material replaced
WiUl one (1) foot of 5"-0 and capped wIth olle (1) foot of I 1/2"-0 mixed with some 3/4"'().
The proof-roll was performed at finished grade of base rock, approximate elevation 480.5',
using a partially loaded double axle dump truck weighing approximately 41,000 pounds.
Slight to moderate deflection was visible under the wheel loads along the east half garage
footing. The area included the garage footing from Ule south end to approximately 23 feet
north. No deflection was visible under the wheciloads for the remainder of the building
pad area, indicating a stable base Is presently available. Mr. Arthur was asked to notify I
our office when additional services are needed.
