Dear Ms. D'Orazio
This letter has been prepared to verify seasonal high groundwater as determined through regular
monitoring unavailable at the time of the previously issued MTI Geotechnical Engineering Report
(B191122g). Descriptions of general site characteristics and the proposed project are available in the
previous report. Unless otherwise noted in this letter, all initial recommendations, limitations, and
warranties expressed in the previous report must be adhered to.
The following table represents groundwater data collected for the site. It should be noted that these
levels will fluctuate from year to year, and are limited to the data collected.
MTI will continue to monitor these wells on a bi-weekly basis. MTI appreciates this opportunity to
be of service to you and looks forward to working with you in the future. If you have questions,
please call (208) 376-4748.
Respectfully Submitted,
Materials Testing & Inspection
