The new senior housing project in Yucca Valley had a minor setback Sunday. According to County Fire Captain Mark Murphy, the pre-fab units were being stored on wood cribbing, about 3 and a half feet off the ground, near the basketball courts behind the Yucca Valley Community Center. Murphy said the wood cribbing, which is like stacked “Lincoln Logs” was leaning, and one of the apartment units fractured and collapsed about 3:15 p.m. due to the poor support structure of the cribbing. Murphy said because several of the other units were leaning and were in danger of falling, the contractor had to bring a crane back to the site and restack the cribbing and the pre-fab units.
