REASONS FOR-RECOMMENDATIONS AND BACKGROUND:
During the winter rains of 2006 a landslide occurred on the slope directly behind 38 Rosewood Court within the
Blackhawk GHAD. Landslide debris entered the rear yard of the property and within several feet of the residence.
Emergency stabilization measures were taken to prevent the landslide from advancing into the residence structure.
The slope and property were temporarily winterized and monitored through the ensuing months.
ENGEO,Inc., a consultant to the District was tasked with evaluating the slide and recommending repair schemes.
On September 14, 2006 a report was issued by ENGEO recommending a geo-synthetic reinforced engineered soil
repair.
Grading operations commenced on October 2, 2006. During grading operations it was determined that the
underlying soil materials beneath the slide were not competent to support the reinstallation of the slide repair
material and it was recommended that additional material be excavated and replaced as engineered fill to support the
slide repair. This additional operation was initiated adding additional costs to the repair. The repair was completed
on December 2, 2006, prior to significant rains.
CONSEQUENCES OF NEGATIVE ACTION:
Without Board of Supervisors' approval,the Blackhawk GHAD will be unable to compensate the Contractor for this
additional work.
