The individual doing the observations and providing direction for the excavation and site
preparation work on the property must sign the following statement.
The undersigned design professional (or authorized employee) attests that he/she
observed required moisture stability procedures on this site, and that such procedures
were accomplished before any changes occurred in the moisture content of the sub-
grade under and around the building (where expansive soils were encountered). The
undersignedfurther attests that the sub-grade, as prepared, is adequate to support the
building proposed for this site.
Additional comments:
(Note): A copy of this report shall be kept on site with the approved plans at all
times.
This report shall be followed by an affidavit, signed and stamped by the design

The geotechnical report for the Mountain-gate Subdivision Phases I & II makes
recommendations for placement of building construction ,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 construction process. Positive site
drainage must be provided.

AFFIDAVIT
For Site Investigation Questionnaire
Foundation Sub-Grade Approval for
Residential Building Site in Mountaingate Subdivision
Phases 1 &2
The undersigned hereby affirms that the excavation, structural fill and moisture
stabilization methods for the building site at the address shown above were observed by
me or an authorized employee of my firm and that the, following is true:
1. The geotechnical information for the subdivision, specific to this site, was utilized
as part of the determination 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 is 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) ,Jv,J U-- 0-2(;)J ~\ Lt:f::in for this building site was completed either by
me or by an hLthorized repr~sentative under my supervision. To the best of my
knowledge, the information contained in that report is complete and accurate.
