The geotechnical repOli for the Mountaingate Subdivision Phases I & II makes
recommendations for placement of building constmction on each site. The report also
recommends that site preparation during wet weather conditions be avoided unless
special measures are taken to mitigate soft soil conditions and moisture collecting in or
around the foundation areas during and after the constnlCtion process. Positive site
drainage must be provided.

Foundation Sub-Grade Approval for
Residential Building Site in Mountaingate Subdivision
Phases 1 &2
The undersigned hereby affimls that the excavation, structural fill aod moisture
stabilization methods for the building site at the address shown above were observed by
me or an authorized employee of my finn and that the following is tlUe:
L The geotechnical infoffi1ation for the subdivision, specific to this site, was utilized
as part of the detem1ination for foundation preparation and drainage requirements.
2. The foundation sub-grade is capable of supporting a minimum of 1500 psf, and is
adequate to support the building proposed for this site.
3. The moisture content of the excavation was adequately maintained during the site
preparation process and the site i~ adequately graded and drained for discharge to
an approved location in order to maintain stable moisture content throughout the
construction process and thereafter.
4. The accompanying report titled "Site Investigation Questionnaire for Consulting
Design Professionals" containing field observations and instructions made on
(date) for this building site was completed either by
me or by ~m authorized representative under my supervision. To the best of my
knowledge, the information contained in that repOlt is complete and accurate.

Inspection of Foundation Fill .
. At your request, we have inspected the in-place density of granular fills place on the subject foundation pad.
The fill consists of approximately 4 to 1 O-inches of %.inch minus dense-graded crushed aggregate.
According to our field-testing' we have determined that the average dry density equals or exceeds 95% of the
maximum as determined by ASTM 0698.
We recommend approval of the fouodation fill, as constructed, by the building official.
Thank you forthe opportunity to be of service. Please call us if you have questions or need further assistance.
Respectfully,
