Following a massive power outage in Southern California, a hydroponic agricultural co-operative experienced a large loss of vegetable crops due to an extreme heatwave. The climate control system’s back-up generator failed during the outage and HMI was asked to assess the extent of the damage and provide a professional opinion as to the cause of loss. HMI had a plant biologist perform extensive testing on the damaged plants and we were able to conclusively determine the cause of loss. HMI also collaborated with forensic accountants to determine the loss of yield, which is a key component of agricultural losses in general. Our findings were conclusive, resolving an insurance claim and providing support for a casualty loss claim as well.
