PROJECT: Old Corral Pit Spokane, WA

Construction Material Testing Subsurface Exploration
Special Inspection
July 24, 2017
Job Number XI 7428
SUBJECT: Results of Subsurface Exploration of Fill Material
This report presents the results of test pit exploration to evaluate fill materials located at the Old Corral Pit. The work was requested to help determine the extent and depths of the fill material located at the site. A vicinity map, site plan, photographs and test pit logs are attached to this report.
We logged 18 test pits at the Corral Pit on 19 & 20 July 2017 throughout the property. The pits were excavated by County Personnel using a John Deer l 80G with a 36" bucket. The pits were excavated to depths until native materials were observed, to the maximum capability or the excavator, or until caving of the pits did not allow for further excavation. The conditions encountered are described in the test pit logs and are illustrated in the attached photographs.
We appreciate the opportunity to be of service. If you have any questions please don't hesitate to call.
