REASONS FOR RECOMMENDATIONS AND BACKGROUND:
During a heavy rain event on March 27, 2006 a landslide occurred on the slope behind 38 Rosewood Court.
Mobilized landslide debris overtopped an existing concrete retaining wall at the rear of the property and deposited
several hundred cubic yards of slide debris within the landscaped back yard of the property at 38 Rosewood
requiring immediate mitigating actions by the GHAD to control the slide and prevent advancement of the debris into
the residence. Impacted during the event was an existing decorative waterfall and intensively landscaped areas
behind the residence.
In September 2006,consulting engineers produced repair schemes including conventional excavation of the failed
area and rebuilding the slope with drained engineered fill.
Construction repair work was commenced on October 10,2006. In an effort to recover and reuse sufficient on-site
soil to rebuild the slope, additional damage was sustained to the existing downslope landscaping. The existing
waterfall,buried in the slide debris sustained irreparable damage as did adjacent landscaping during the operation.
This operation was necessary to facilitate the repair and alternative methods,including harvesting nearby material
and importing new material, were deemed economically impractical.
On November 21, 2007 remedial landscaping estimates were received from Cagwin & Dorward Landscape
Contractors for the repair of the waterfall and surrounding hardscaping damaged during the soil recovery operation.
Since this damage was sustained during the construction operations,this part of the remedial landscaping is to be
funded under the construction repair portion of the GHAD's annual budget for FY2007/2008.
CONSEQUENCES OF NEGATIVE ACTION:
Without Board approval, the District would be unable o fully restore the site and would not be fullfilling a tenet
of its Plan of Control allowing for this restoration work.
