Report (7) Hoggans Park, Tigard, Oregon
GeoPacific Project No. 15-3654
Construction should include typical measures for controlling subsurface water beneath the
homes, including positive crawlspace drainage to an adequate low-point drain exiting the
foundation, visqueen covering the exposed ground in the crawlspace, and crawlspace ventilation
(foundation vents). The homebuyers should be informed and educated that some slow flowing
water in the crawlspaces is considered normal and not necessarily detrimental to the home given
these other design elements incorporated into its construction. Appropriate design professionals
should be consulted regarding crawlspace ventilation, building material selection and mold
prevention issues, which are outside GeoPacific's area of expertise.
We have prepared this report for Westwood Homes, LLC and it should not be relied upon by third
parties without consulting GeoPacific. Within the limitations of scope, schedule and budget,
GeoPacific attempted to execute these services in accordance with generally accepted
professional principles and practices in the fields of geotechnical engineering and engineering
geology at the time the report was prepared. The conclusions and interpretations presented in
this report should not be construed as a warranty of the subsurface conditions.
No warranty, expressed or implied, is made. The scope of our work did not include flood hazard
evaluations, environmental assessments, the presence or absence of wetlands; or potential
hazardous substances in the soil, surface water, or groundwater at this site.
We appreciate this opportunity to be of service.
Sincerely,
