Geo-Advantec, Inc.

Scope Of Work

As an environmental friendly approach, the City intended to design and construct on-site storm water disposal systems in several streets. Geo-Advantec was employed to perform a geotechnical investigation at Cienega Avenue, Monte Vista Avenue and Via Verde Street. The total length of the project was about 3 miles. We conducted 15 borings using a hollow stem drilling rig and the borings were advanced to a maximum depth of 25 feet. The laboratory tests were performed on the soil samples collected from different layers. Based on the tests results analysis, the preliminary permeability of soil layers at each location was determined and reported. We provided the city with the final profile of soil stratigraphy and their permeability properties. The report assisted the City in determining the future possibilities of using on-site disposal system and would be used as a guide in determining the locations of future field percolation tests.
