Due to the <br /> skill of the operator (Danny Gonzalez), it was possible to excavate down to the <br /> end of the pipe from the street side of the fence, resulting in no rutting or <br /> compaction of the wetland by the backhoe. Also, by using a very small bucket, <br /> a minimum amount of material was excavated and even this was sidecast so as not <br /> to impact the wetland. <br /> A concrete pancake was cut and cemented into the end of the pipe. It was the <br /> concensus of Deborah Evans and myself that the hole should be backfilled to <br /> prevent it from filling with water and becoming a safety hazard since it was <br /> about 6 to 7 feet deep. Using very clean sandy loam with some bar run in it <br /> that had recently been excavated from a landscape area at the treatment plant, <br /> it was possible to fill the hole from the street and it was not necessary to <br /> back the dump truck onto the wetland. After rough grading with the backhoe, <br /> the crew and myself graded and leveled the fill using shovels, straightened up <br /> the fence, and swept up the work site. <br /> The entire operation went off without a hitch, thanks to both the skill and <br /> efficiency of the repair crew. I would like to commend both Danny Gonzalez <br /> and Bob Edmiston not only for their efficient skillful work but for the concern <br /> they showed in minimizing any impact to the wetalnd area during the entire <br /> repair operation. <br /> Jack Long <br /> . w <br />
