Show I ' ' Officials digesting Spruce report tied to a single factor. It asserts yard watering, runoff waters, leaks in utility service lines and some "surficial" flooding and water used to compact backfill in utility trenches are all suspect. The report recommended several precautions, among them: -Checking utility lines for leakage, and immediately repairing any leaks. -Grading lots to direct surface water away from the house. -Installing gutters with downspouts, with the discharge placed at least 15 feet away from the house, and so it will flow away from the home. -Replacing "permeable" backfill around basements with "impermeable" "im-permeable" soils "properly placed and compacted. -Reducing yard watering. The separate tests in Sunrise Subdivision Sub-division produced results "better than we had initially expected," said the report. It did say, however, that the presence o of collapsible soils still was confirmed in the area. If also recommended a host of precautions before building is begun in the yet-undeveloped subdivision. Most were similar as those for Spruce Street, but some new measures were included: -Assure the soils have stopped settlement set-tlement before excavation begins. -Not allowing gravel bedding for utility lines and ponding as a means of compacting backfill. -Plowing the upper 18 inches of soil around the structure and running "moderate weight rubber tire-mounted equipment over the soil at least twice." By LEE WARNICK Record Editor Cedar City officials are in the process of digesting a host of recommendations contained in the long-awaited Dames and Moore subsidence study on Spruce Street and Sunrise Subdivision. The 20 pages of summaries basically said that Cedar City could continue to safely allow new construction at the two locations, if they require certain precautions before building. But for residents of the four stricken homes on Spruce Street, the news was not as good. "Once settlement resulting from the 'wetting' of collapsible soils starts in developed areas ... it is extremely , difficult to control on a long-term basis," the report said. I It went on to say that subsidence I areas tend to "feed upon themselves," 1 and that even precautionary measures J to prevent additional subsidence "by I themselves, may" not eliminate future I settlements." The two remedial alternatives forwarded for-warded by Dames and Moore are to either move the affected homes or place them over "deep foundations" that extend into "non-moisture sensitive sen-sitive soils." This may or may not require the four homes to be temporarily tem-porarily moved from their foundations, the report continued. For other residents of Spruce Street, the report continued to leave them in suspense concerning their possible susceptibility to subsidence. Dames and Moore felt other homes on the street are not subsiding because: "One, the underlying soils are not as highly moisture sensitive; two, the soils are not moisture sensitive; or three, moisture sensitive soils, if present, have not experienced significant "wetting." The report did not hypothesize on which of the three possibilities they felt most likely. The report also said it feels causes for the Spruce Street subsidence cannot be |
