These structures must remain structurally sound throughout periods of flooding and be capable of sustaining all forces associated with flooding. The structures should require no more than flushing with a hose to become operational after the flood event has passed. No water damageable materials are allowed. · Closed floodable, wet flood-proofed structures are described as those structures that are necessary for carrying out, or are related to, authorized project purposes and are susceptible to periodic flooding. These structures must remain structurally sound throughout periods of flooding and be capable of sustaining all forces associated with flooding. The structures should require no more than minimal maintenance to become operational after the flood event has passed. No water damageable materials are allowed.
