The SFIP does, however, pay for losses from mudflow and land subsidence as a result of erosion that are specifically insured under the definition of flood, Section II.A.1.c and Section II.A.2.
Note: The adjuster should recognize and immediately report potential structural instability of the insured property to the NFIP DSA or the WYO company and recommend that a qualified licensed expert conduct an on-site inspection of the insured building. The expert should provide a comprehensive report detailing causation of the settlement/subsidence including photographs of the structure.
