We <br /> understand that the city will retain Inter Fluve, Inc. and CDM, separately, to complete the <br /> work To this extent, we have submitted the required information to renew our on-call <br /> contract with the City. Lori Davis was most helpful in this effort. The information was <br /> submitted last week <br /> Our initial proposal was to investigate the restoration site with backhoe test pits. This <br /> met with opposition from the adjacent homeowners who feared excessive damage to the <br /> vegetation. We, therefore, reluctantly drilled hand auger holes with the full realization <br /> that the information gained might not be conclusive. The information from the manually <br /> drilled holes indicated a thin soil layer over "refusal", which is interpreted as bedrock <br /> ~ ' based on drill action and a geologic reconnaissance. Shallow bedrock is observed in the <br /> creek channel above and below Frederick Court. <br /> s <br /> Our discussions with Inter Fluve indicate that the near surface presence of bedrock is <br /> critical to their final design. Therefore, we gave Inter Fluve a proposal to provide: l) <br /> approximately 8 shallow, rubber-tired, backhoe~xcavated test pits (limited to 6 hours), 2) <br /> inspection by an experienced field representative, 3) logs of the test pits, and 4) a brief <br /> report of findings. We understand that the City would prefer that we not use afull--sized <br /> rubber-tired backhoe to limit the environmental site impact and concerns of residents. <br /> Therefore, we are in the process of retaining a small, track-mounted backhoe of the <br /> ~ Kubota variety, commonly used by landscapers. It is imperative that the City realize, and <br /> convey to local property owners, that there will necessarily be some damage to vegetation <br /> a~-Rrso~ws;o,~crsvc~y raq«»w~«~fw,~ o..+a~.ax <br /> <br />
